The object of the present invention relates to a device for facilitating the installation of walling and/or wall-insulation, which has a grid structure containing longitudinal supports and lateral supports connecting these longitudinal supports to each other positioned at a distance from each other with main axes at an angle to the longitudinal supports.

Numerous solutions have become known of for producing the walling of buildings and other structures made from various materials, such as bricks and post-hardening materials, such as concrete, and for the provision of the walling with subsequent insulation.

Shuttering structures made from prefabricated elements have been put to use in recent times in the case of the use of post-hardening building materials. Among others, such a solution is disclosed by patent specification registration number HU 154.380. However, the deficiency of such auxiliary devices is that they cannot be used for the construction of brick walls or for the subsequent insulation of reinforced concrete walling. A further disadvantage of such solutions is that they cannot be economically used for the production of smaller structures and buildings.

The walls of structures made from traditional construction elements, such as bricks are even today made using bricklayer workstations created by erecting scaffolding. Such scaffolding structures are disclosed in, among others, patent specifications registration numbers HU 79.551 and HU 81845. The essence of these is that temporary scaffolding consisting of longitudinal and lateral supports is assembled next to the position of the wall to be produced and the higher parts of the wall are laid from this scaffolding.

The disadvantage of the given solution, however, is that they do not help in establishing a straight wall, they only help the persons performing the work to reach the parts of the wall above the height a person can reach so that they can build this too. However, the disadvantage of the manually laid wall is that due to deviations from the desired plane, when plastering the bare wall a significant amount of plastering material needs to be used in order to correct the faults caused by deviations from the desired plane, which considerably increases the labour and material requirement of the construction work, i.e. this unjustifiably increases the production costs of the structure. The same problems arise during the subsequent insulation of various buildings, such as residential buildings. In the course of this the insulation elements used have to be affixed to the side of the wall to be protected, then rendering has to be applied to the heat insulation cladding. However, if the external surface of the basic wall is not planar then the planar deficiencies have to be corrected with the help of the adhesive and/or rendering material, which in this case also involves extra labour and materials use.

The objective with the device according to the invention was to overcome the deficiencies of the known solutions and to create a device that facilitates the production of walling and subsequent heat insulation that can be quickly and simply installed and dismantled similarly to scaffolding, and with its use the fapade surface of the walling to be produced can be created so that it is in a single plane, or so that the external surface of the heat insulation elements to be subsequently applied to an existing wall are also installed in a single plane.

The recognition that led to the device according to the invention was that if elements with a unique structure that have a suitably established base surface are connected to each other in a unique way so that the independent base surfaces comprising a unified whole with respect to essentially a single vertical and horizontal direction form a suitably adjustable contact surface, then the construction elements of the wall structure to be established can be fitted up to this surface, or the insulation elements forming the heat insulation cladding can be installed at the appropriate spacing, so that their sides facing the base surface are essentially positioned in a single plane and so that after the device is dismantled a wall surface is created that has a planar fapade surface that meets expectations that does not require subsequent work demanding further significant labour, and in this way the task can be solved.

In accordance with the set objective device according to the invention for facilitating the installation of walling and/or wall-insulation, - which has a grid structure containing longitudinal supports and lateral supports connecting these longitudinal supports to each other positioned at a distance from each other with main axes at an angle to the longitudinal supports, is established in such a way that the inner support surfaces of the lateral supports forming a given grid structure are positioned in a single support plane, and, furthermore, that the individual grid structures are supplied with at least one connection device and/or position-fixing fitting suitable for connecting them together along their neighbouring longitudinal supports, and each two neighbouring grid structures are secured to each other with the use of one or more connection devices and/or one or more positionfixing fittings, where the position-fixing fitting has a first connection element and a second connection element, the first connection element of the position-fixing fitting is rigidly connected to at least one of the longitudinal supports of the grid structure and/or to at least one of the lateral supports of the grid structure, and the second connection element of the position-fixing fitting is stably secured to a carrying surface supporting the grid structure and/or to the walling to be insulated.

A further feature of the device according to the invention may be that the connection device contains a threaded shank and at least one nut collaborating with the threaded shank, furthermore a connection opening is established in at least one longitudinal support and/or in at least one lateral support of the grid structure, the threaded shank of the connection device passes through the connection openings of neighbouring grid structures, and the neighbouring grid structures are, in this way, linked next to one another.

In the case of a different embodiment of the device the first connection element of the position-fixing fitting has a pin member, where the pin member is supplied with a connecting-threaded part, and the connecting-threaded part of the pin member is supplemented with at least one clamping nut, while the second connection element of the position-fixing fitting has a fixing piece, where the fixing piece has a connection ring that has a conical threaded protrusion or accommodation opening as a continuation of the pin member. Optionally the pin member of the position-fixing fitting is made to pass through the connection opening and is secured to the longitudinal support or the lateral support of the grid structure with the clamping nuts.

From the point of view of the device it may be preferable if the position-fixing fitting is coupled with an anchoring body, and the connection ring of the fixing piece of the position-fixing fitting is connected to the anchoring body that runs through the accommodation opening, and the anchoring body is secured to the supporting surface. In the case of yet another different embodiment of the invention at least one of the outer longitudinal supports of the grid structure is coupled with a spacer piece, where the spacer piece has a base member with a support surface facing towards the walling and/or the wall insulation to be constructed, and a brace member that has a main plane at an angle of between 70 to 110° to the support surface of the base member, and guide passages with their longitudinal axes in the main plane are arranged in the brace member. Optionally the pin member of the position-fixing fitting is inserted into the guide passage of the spacer piece, and is firmly secured there with clamping nuts, while the conical threaded protrusion of the position-fixing fitting is firmly secured into the walling to be insulated.

In the case of yet another different embodiment of the device the inner surfaces of the longitudinal supports of the grid structure are positioned in a plane different to the supporting plane carrying the inner support surfaces of the lateral supports, and in this way the inner surfaces of the longitudinal supports form an accommodation zone with a depth serving for receiving the base member of the spacer piece, where the depth between the internal surface of the longitudinal support and the supporting plane carrying the internal support surfaces of the lateral supports is at least as large as the thickness of the base member of the spacer piece.

In the case of another embodiment of the invention the inner surfaces of the longitudinal supports of the grid structure and the inner support surfaces of the lateral supports are positioned in the same support plane, an accommodation groove of a depth sufficient for receiving at least a part of the base member of the spacer piece is established near to the longitudinal outer edge of the longitudinal supports of the grid structure, running at least partly all along the longitudinal outer edge, where the depth of the accommodation groove is at least as large as the thickness of the base member of the spacer piece.

In the case of yet another embodiment of the device a shaped seating flange protruding from the support plane is located on the lower part of the grid structure, in the vicinity of the lower edge of the lower lateral support.

From the point of view of the invention it may be preferable if a height-adjustment fitting is positioned protruding downwards out of the lower end of the spacer piece. The height-adjustment fitting has a base resting on the supporting surface, an adjustment extension protruding from the base, and a threaded connection element secured to the grid structure, in addition one or more receiving tabs suitable for supporting the grid structure are arranged at the lower end or in the proximity of the spacer piece.

The most important advantage of the device according to the invention is that as a consequence of the novel interconnection of the uniquely designed grid structure, and its unconventional adjustable securing, an extensive support surface may be created in a short time, using simple structural elements, which serves as a base surface for construction elements or heat insulation elements to rest against without any further levelling adjustment being necessary so that the constructed wall structure or fa ade surface of heat insulation cladding essentially forms a single plane.

Another advantage resulting from this is that in addition to the process of constructing the wall taking less time, it results in a more precise and faultless surface that does not require the correction of bricklaying faults with a thick layer of plaster. In this way, on the one part, the overall amount of labour invested to construct the wall structure and, on the other part, the amount of plastering material used can be reduced. Therefore these advantages may result in a reduction in unit cost and an increase in productivity.

Another feature that may be viewed as an advantage is that the device is easy to put together and the assembly of the components does not require specialist knowledge either.

It is also an important advantage that when using the device according to the invention the heat insulation elements to be secured to the walling can also be fixed using an adhesive foam, such as polystyrene foam, as a result of the bottom and side supporting effect of the device, in this way the heat insulating ability of the entire wall structure can be significantly improved as compared to heat insulation elements secured with cement-based adhesives.

Further details of the device according to the invention will be explained via exemplary embodiments with reference to figures, wherein: Figure 1 depicts a side view of a possible version of the device according to the invention in partial cross-section,

Figure 7 depicts a detail of a version of the grid structure belonging to the device according to the invention.

Figures 1 and 2 show a version of the device according to the invention that is suitable for facilitating the construction of space-dividing walls 2. Here the grid structure 10 is installed directly onto the supporting surface 1. In the case of this embodiment of the invention, however, it is important for the supporting surface 1 to be a horizontal, smooth surface, and have suitable load-bearing ability, and it should also be suitable for securing the anchoring body 34 serving for securing the grid structure 10 into it firmly and rigidly. Such a supporting surface 1 may be, for example, the concrete foundation of a building structure, or even a reinforced concrete floor structure.

It may be observed that the grid structure 10 contains two parallel, preferably vertically positioned, longitudinal supports 11, and lateral supports 12 positioned between and across the longitudinal supports 11. The angle between the main axes l la of the longitudinal supports 11 and the main axes 12a of the lateral supports 12 here is the 90° angle“a”. Naturally, the angle“a” may deviate from 90° between certain limits, but from the point if view of production technology and use a perpendicular angle“a” is the most preferable. In the case of the given embodiment the lower edge 12c of the bottommost lateral support 12 of the grid structure 10 rests upon the horizontal base-forming support surface 1. In the present case both the longitudinal supports 11 and the lateral supports 12 are aluminium section, which may be connected to each other with adhesive or cohesive bonding. It must be noted here that the grid structure 10 may be made of any material, but the basic material must be able to suitably withstand greater physical effects, especially impacts caused by the construction elements when the walling 2 is being laid.

It is also visible in figure 2 that the main axes 12a of the parallel lateral supports 12 are located at a distance“T” from each other, therefore it is possible to reach through the grid structure 10 in certain places. Essentially the lateral supports 12 serve the purpose of guides up to which the construction elements comprising the walling 2 can be installed against while the walling 2 is being laid. Therefore their density of installation, i.e. the magnitude of the distance“T” may depend on the size of the construction elements used to create the walling 2.

Figure 1 , however, shows that the inner surface l lb of the longitudinal supports 11 facing the walling 2 to be constructed and the inner support surface 12b of the lateral supports 12 facing the walling 2 fall in the same single support plane“TS”. This support plane“TS” forms the base of the fa5ade surface of the walling 2.

Figure 2 better illustrates how two neighbouring grid structures 10 are connected to one another. In the case of the given embodiment connection openings 13 are established in the longitudinal supports 11 of the grid structure 10. The threaded shanks 21 of the connection devices 20 pass through these connection openings 13, with the threaded shanks 21 having nuts 22 at their ends. It should be noted here that the surfaces of the longitudinal supports 11 of the grid structure 10 in the vicinity of the connection opening 13 may be provided with orienting pieces - not indicated in the figures - that aid precise connection.

It may also be observed in figure 1 how the support plane“TS” formed by the inner surfaces 11b of the longitudinal supports 11 of the grid structure 10 and the inner support surfaces 12b of the lateral supports 12 are set to a vertical position. It can be seen that in the case of this embodiment a connection opening 13 is located in the vicinity of the upper end of at least one of the longitudinal supports 11 of the grid structure 10 that is perpendicular to both the main axis l la of the longitudinal support 11 and the main axis

12a of the lateral support 12. Therefore this connection opening 13 is also perpendicular to the support plane“TS”. The pin member 31a of the first connection element 31 of the position-fixing fitting 30 is inserted into this connection opening 13. It must be noted here that the connection openings 13 cooperating with the connection device 20 and the position-fixing fitting 30 may also be positioned in the lateral supports 12 and not only in the longitudinal supports 11.

Incidentally the position-fixing fitting 30 consists of three parts. The one is the first connection element 31 , the second is the second connection element 32, and the third is the clamping nut 33. The second connection element 32 is established as the continuation of the first connection element 31. The pin member 31a of the first connection member 31 has connecting-threaded parts 3 lb. The first connecting-threaded part 3 lb is at the end of the pin member 31a located towards the inner surface l ib of the longitudinal support 11. While the second connecting-threaded part 3 lb is located at the part of the pin member 3 la located towards the fixing piece 32a of the second connection element 32. In this case, in the interest of facilitating assembly, the pin member 3 la of the first connection element 31 has a thread throughout its entire length, and so here the connecting-threaded part 31b runs along the entire length of the pin member 31a.

The fixing piece 32a of the second connection element 32 has a connection ring 32c in which the accommodation opening 32d is established. The anchoring body 34 is inserted into the accommodation opening 32d established in the connection ring 32c forming the fixing piece 32a of the second connection element 32 of the position-fixing fitting 30, the end of which anchoring body 34 opposite the second connection element 32 is secured into the hard supporting surface 1 in such a way that it cannot move.

The use of the device shown in figures 1 and 2 takes place in the following way. First of all two grid structures 10 need to be positioned next to one another onto the flat supporting surface 1, and the threaded shanks 21 of the connection device 20 need to be threaded through the connection openings 13 of the neighbouring longitudinal supports 11 that are parallel to the main axis 12a of the lateral support 12. Then the nuts 22 need to be screwed onto the two ends of the individual threaded shanks 21. In this way two neighbouring grid structures 10 can be secured together by clamping together the longitudinal supports 11 next to one another by using the connection devices 20.

Following this a clamping nut 33 has to be screwed in until the connecting-threaded part 31b of the pin member 3 la belonging to the first connection element 31 of the positionfixing fitting 30 located closer to the fixing piece 32a of the second connection element 32. Then after assembling the first two connected grid structures 10 the first connection element 31 of the position-fixing fitting 30 needs to be threaded through the connection opening 13 perpendicular to the support plane“TS” and located at the upper end of the longitudinal support 11 in such a way that the fixing piece 32a of the second connection element 32 and the clamping nut 33 located closer to it are positioned on the side of the grid structure 10 opposite the support plane“TS”.

Following this another clamping nut 33 needs to be screwed onto the connecting- threaded part 31b of the pin member 31a of the first connection element 31 that protrudes towards the support plane“TS” of the grid structure 10. Finally the first end of the anchoring body 34 needs to be guided through the accommodation opening 32d located in the supporting protrusion 33c forming the fixing piece 32a of the second connection element 32 of the position-fixing fitting 30, while the second end of the anchoring body 34 needs to be secured into the supporting surface 1. In this way now the two grid structures 10 secured together with connection devices 20 are standing on the supporting surface 1.

In the course of setting the support plane“TS” formed by the inner surfaces 11b of the longitudinal supports 11 and the inner support surface 12b of the lateral supports to the vertical the clamping nuts 33 need to be adjusted on the pin member 31a of the first connection element 31 of the position-fixing fitting 30 so that the grid structure 10 itself gets closer to or more distant from the connection ring 32c of the fixing piece 32a forming the second connection element 32 of the position-fixing fitting 30. So when the support plane“TS” has been set to the vertical and the clamping nuts 33 on the connecting- threaded part 31b are tightened, the grid structures 10 can be secured to the anchoring body 34 secured into the supporting surface 1 so they are unable to move, and therefore the grid structures 10 can be maintained in the desired vertical position. Following this further grid structures 10 can be connected to the grid structures 10 that are already standing and adjusted in the way described above with the difference that these can be added one-by-one to those already installed and adjusted.

After linking up and adjustment of the desired number of grid structures 10 essentially the vertical grid structures 10 standing next to one another forming the support plane“TS” create that reference surface along the length of the walling 2 to be constructed up to which the individual construction elements can be laid thereby constructing the walling 2 that has a substantially flat facade surface.

Moving over now to the device disclosed in figures 3 to 6, an embodiment is presented there with the help of which wall insulation 3 can be produced on the fapade surface of an already existing walling 2 in such a way that the external surface of the wall insulation 3 opposite the walling 2 forms a single plane irrespective of the irregularities of the fapade surface of the original walling 2. This is important because the application of the external rendering that follows the installation of the wall insulation can be performed in a much simpler way, more quickly, more effectively, and with the use of less material.

Figures 3 and 4 show a device in the case of which the grid structures 10 are also assembled from two longitudinal supports 11 and lateral supports 12 located between them. Flere too the parallel main axes 12a of the lateral supports 12 are arranged at a given distance“T” from each other. The main axes 11a of the longitudinal supports 11 and the main axes 12a of the lateral supports 12 are at the 90° angle“a” to each other.

However, the fundamental difference here is that, as shown in figure 4, the inner surfaces 11b of the longitudinal supports 11 are recessed by the depth“M” as compared to the support plane“TS” formed by the inner support surfaces 12b of the lateral supports 12.

The other significant difference is that here spacer pieces 40 link the neighbouring grid structures 10 to each other, and the grid structures 10 do not rest up against the supporting surface 1 , instead, as shown in figure 3, they rest on the receiving tabs 45 located at the lower ends 44 of the individual spacer pieces 40. Another significant difference is that the adjustment of the gap between the support plane“TS” formed by the lateral supports 12 of the grid structure 10 and the walling 2, serving as the space for the wall insulation 3 elements and of the vertical position of the support plane“TS” here is realised with the help of a position-fixing fitting 30 that is of a different design to the previous one, which is illustrated in detail in figure 5.

Another important difference is that here the position-fixing fitting 30 is not secured to the grid structure 10, instead it is inserted into the guide passages 43 of the spacer piece 40. Incidentally the spacer piece 40 comprises a base member 41 and brace member 42.

Figure 5 well illustrates that the main plane“FS” of the brace member 42 is at the perpendicular angle“b” to the support surface 41a of the base member 41 of the spacer piece 40 facing the walling 2. It can also be observed that those guide passages 43 are established in the brace member 42 of the spacer piece 40 through which the pin member 31a of the first connection element 31 of the position-fixing fitting 30 pass through. Naturally the longitudinal axis 43a of the guide passage 43 also lies in the main plane“FS” of the brace member 42, and is perpendicular to the support surface 41a of the base member 41.

The position-fixing fitting 30 comprises the first connection element 31 and the second connection element 32, which form an organic unit with each other. The pin member 3 la of the first connection element 31 has a connecting-threaded part 31b, which the clamping nuts 33 may be connected to. The fixing piece 32a of the second connection element 32 is a conical threaded protrusion 32b which is suitable for being screwed into the walling 2 and being temporarily secured there.

Figure 4 illustrates the relationship between the thickness“V” of the base member 41 of the spacer piece 40, and the depth“M” between the inner surface l ib of the longitudinal support 11 of the grid structure 10 and the support plane“TS”. In the interest of the given device being useable the depth“M” must be at least the same value as the thickness“V” of the base member 41 of the spacer piece 40. The reason for this is that in this case the accommodation zone l id delimited by the inner surface l ib of the adjacent longitudinal supports 1 1 of the two neighbouring grid structures 10, and the support plane“TS” formed by the inner support surface 12b of the lateral supports 12 and the threaded shank 21 forms a straight block shape with precisely the dimensions, or slightly greater dimensions into which the parts of the base member 41 protruding to the side in the one or the other direction from the brace member 42 of the spacer piece 40 fit.

In the case suitable dimensions are selected the plane“S” carrying the support surface 41a of the base member 41 of the spacer piece 40 and the support plane“TS” formed by the inner support surfaces 12b of the lateral supports 12 of the grid structure 10 comprise a single plane.

Returning now to figure 3, it also shows that the height-adjustment fitting 50 is located at the lower end 44 of the spacer piece 40. The height-adjustment fitting 50 in the case of this embodiment consists of a base resting on the supporting surface 1, a threaded connection element 53 secured to the lower end 44 of the spacer piece 40, and an adjustment extension 52 pivotally connected to the base 51 and connected to the threaded connection element 53 with a thread. The task of the height-adjustment fitting 50 is to make it possible to adjust the grid structure 10 to the horizontal as compared to the supporting surface 1 , in other words so that the lower edge 12c of the bottommost lateral support 12 of the grid structure 10 can be set to be horizontal irrespective of the unevenness of the supporting surface 1.

Moving over now to figure 6, it shows a side view of the grid structure 10. It can also be seen here that the inner surface 11b of the longitudinal support 11 and the inner support surfaces 12b of the lateral supports are not located in the same plane, and the accommodation zone l ld forming the difference is filled by the wing of the base member 41 of the spacer piece 40. It can also be observed, however, that a shaped seating flange 14 is located at the lower edge 12c of the bottommost lateral support 12 of the grid structure 10.

The task of the shaped seating flange 14 is to support the insulation panels located in the bottommost row when the wall insulation 3 is being constructed, and to maintain them in a position so that the foam material used for fixing can be easily placed between the walling 2 and the insulation panels forming the wall insulation 3. It should be noted here that the shaped seating flange 14 is preferably adjustable, in this way in the case of wall insulations 3 of various thicknesses it can always be adjusted to suitably support the initial insulation panels of the wall insulation 3.

The device presented in figures 3 to 6 is used as follows. First of all the spacer pieces 40 must be positioned along the walling 2 to be insulated with the help of a size template equal to the width of the grid structure 10. For this the individual spacer pieces 40 must be set on the base 51 of the height-adjustment fitting 50, then the pin member 31a of the first connection element 31 of the position-fixing fitting 30 must be threaded through the guide passages 43 located in the brace member 42 of the spacer piece 40 in such a way that the conical threaded protrusion 32b forming the fixing piece 32a of the second connection element 32 faces the walling 2.

A clamping nut 33 must be screwed onto the connecting-threaded part 31b, from the conical threaded protrusion 32b, of the pin member 3 la that has been pushed through the guide passage 43, then the first connection element 31 of the position-fixing fitting 30 must be secured into the walling 2 with the help of the conical threaded protrusion 32b of the second connection element 32.

After the first connection element 31 has been secured a clamping nut 33 must be screwed onto the connecting-threaded part 3 lb of the pin member 31a of the first connection element 31 still freely protruding from the guide passage 43 in the brace member 42 of the spacer piece 40. In this way the spacer piece 40, on the one part, stands on the supporting surface 1 and, on the other part, is connected to the walling 2. In such a case it is possible to make the support surface 41a of the base member 41 of the spacer piece 40 and the plane“S” carrying it vertical so that the support surface 41a is positioned at the desired distance from the walling 2.

This operation may be performed with the clamping nuts 33 screwed onto the connecting-threaded part 3 lb on the pin member 3 la of the first connection element 31 of the position-fixing fitting 30. The nut near to the support surface 41a of the base member 41 of the spacer piece 40 must be adjusted so that the distance between the walling 2 and the support surface 4la is appropriate. Then the adjustment extension 52 of the height- adjustment fitting 50 must be rotated around the threaded connection element 53 so that the lower ends 44 of the spacer pieces 40 lie in a horizontal plane.

When this position setting takes place then a grid structure 10 can be installed between two neighbouring spacer pieces 40 in such a way that the bottom of the grid structure 10 rests upon the receiving tabs 45 located at the lower ends 44 of the individual spacer pieces 40, while the inner surfaces l ib of the longitudinal supports 1 1 of the grid structure 10 come into contact with the side of the base member 41 of the spacer piece 40 opposite the support surface 41 a.

With the grid structure 10 in this position the accommodation zone l ld of the longitudinal support 1 1 entirely accommodates the one wing of the base member 41 of the spacer piece 40, and in this way the plane“S” of the spacer piece 40 and the support plane “TS” formed by the lateral supports 12 of the grid structure 10 lie in the same plane.

After a grid structure 10 has been positioned on each of the two sides of a spacer piece 40, the clamping nuts 33 can be screwed onto the connecting-threaded part 3 lb of the brace member 42 of the spacer piece 40, which connecting-threaded part 3 lb protrudes out of the guide passage 43, and by tightening these and the clamping nuts 33 on the support surface 41a of the base member 41 of the spacer piece 40 the grid structures 10 can be firmly secured to the spacer pieces 40 in such a way that the support planes“TS” facing the walling 2 and the planes“S” provide a single flat base surface for the wall insulation 3 to be installed.

After the device used as a template has been assembled the individual insulation panels can be passed through the openings between the lateral supports 12 of the grid structure 10 into the space between the device and the walling 2. The first row can be laid onto the shaped seating flange 14 protruding under the bottommost lateral support 12 of the grid structure 10 or from its lower edge 12c. As a consequence of the shaped seating flange 14 the insulation panels laid in this first row rest in the space between the walling 2 and the device so that their upper edge tilts towards the support plane“TS” of the grid structure 10. In this way the foam materials used for fixing the panels can be easily injected in between the walling 2 and the insulation panel. On continuing the gluing process the slightly expanding adhesive foam material pushes the insulation panel up against the lateral supports 12 of the grid structure 10 od the device, and so after the adhesive has set and the device has been dismantled, irrespective of the irregularities of the walling 2, wall insulation 3 is established so that its side opposite the walling 2 is substantially flat, which can then be easily rendered using a small amount of material.

When dismantling the device first the external clamping nuts 33 have to be removed from the connecting-threaded part 3 lb of the first connection elements 31 of the individual position-fixing fittings 30, protruding from the brace member 42 of the spacer piece 40. After this the grid structures 10 can be lifted off the receiving tabs 45 of the spacer pieces 40. Finally by turning the adjustment extension 52 of the height-adjustment fittings 50 of the spacer pieces 40 the bases 51 can be released, and so the spacer pieces 40 can be pulled from the walling 2. In this way only the second connection elements 32 supporting the first connection elements 31 of the position-fixing fittings 30 are secured in the walling 2. After these have been unscrewed the first connection elements 31 can also be removed from the walling 2, and so the wall insulation 3 can now be rendered.

For the sake of completeness it must be noted here that the pin member 3 la of the first connection element 31 of the position-fixing fitting 30 may also be a commercially available threaded rod. In this case the connecting-threaded part 3 lb essentially runs along the entire length of the pin member 3 la of the first connection element 31.

Moving over now to figure 7, this shows a detail of another version of the grid structure 10. This also includes the longitudinal support 11 and the connected lateral support 12. The only difference is that a part of the inner surface 11b of the longitudinal supports 11 lies in the support plane 'TS” formed by the inner support surfaces 12b of the lateral supports 12. In addition the accommodation zone 1 Id is established so that a groove with the depth“M” is made in the inner surface l lb of the longitudinal support 11 along the longitudinal external edge 1 1 c. Apart from this the use and assembly of the grid structure 10 is the same as that presented in the case of figures 3 to 6. The device according to the invention made be used to good effect in all places where walling or wall insulation needs to be made simply, quickly, effectively in good quality in such a way that it has a flat fa9ade surface.
