PANEL FOR WALL OR SLAB FOR DRY CONSTRUCTION WITH A PROFILE ARRANGED PERIPHERALLY WITH A SLOTTING RECESS, AND MANUFACTURING PROCESS

THEREOF

Technical field

The present disclosure pertains to prefabricated and industrialised manufacture, in particular a prefabricated wall panel, preferably light, and slab, the respective fittings and the industrial manufacturing and assembly procedure.

Background

In recent years there has been a major contribution by various industrialised systems, namely using concrete, metal and wood, to increase the speed, efficiency and thoroughness of the construction. Objectively, some of the main purposes of light prefabricated construction can be referred to: sustainability; low consumption of fossil fuel; weight/resistance ratio; thermal inertia; with a diversity of types, features and products.

Today various construction systems appear which are very different from the traditional systems - in the case of wood, for example, the traditional system involving logs or self- supporting panels or frameworks. The latter, having served as the point of departure for the first attempt to implement an industrialised wood construction system - the General Panel System (1941) - by Konrad Wachsmann and Walter Gropius, had the limitation of constituting a closed system, without the features of flexibility, adaptability and combination with other systems. Today, the new technologies - mainly CNC digital ones - allow open systems, quite often based on unit series logics, to constitute an unavoidable, desirable reality in terms of business and industrial strategy - this is also how the technology of the present disclosure fits in. These strategies are aimed at the obtaining of products endowed with high resistance and typification and which can be combined with other construction systems.

General description

The present disclosure pertains to prefabricated construction, in particular a wall panel or slab for a building which includes two main faces which are parallel to each other each being made up of a permanent formwork board and lateral and end faces each comprising a profile arranged longitudinally to said faces, forming a rim in which said rim includes a longitudinal recess for a slot to receive one or more longitudinal parts for slotting into the recess of the lateral face profile of another panel and which, in its interior, includes a filling which was deposited and cured, with the aid of vents, in said permanent formwork boards and the filling is preferably light. A permanent formwork is a formwork that stays in place after curing.

The panel may be assembled in modular structures very effectively, allowing the great spaciousness of the interior spaces, speed of implementation, low costs and simple assembly, in particular, 100% dry assembly of the whole construction, for example, dispensing with the use of mortar and the present solution is endowed with higher architectonic and construction quality.

The aforementioned characteristics allow greater lightness to be obtained, a lower material cost, more space for the possible installation of insulations and technical infrastructures and more space for any possible structural reinforcements.

The point of departure of the disclosure is light concrete panels, namely using EPS, rice husks, cork particles, wood fibres or hemp straw and/or fibres. The improvement is related with the introduction, at an industrial production stage, of a profile, for example, an extruded aluminium profile, on the perimeter of the panel. This profile, studied in depth to comply with various requirements in terms of watertightness, waterproofing and binding with the other materials, ensures the compliance of the fully dry construction (main concept which underlies these projects), replacing other bonding processes between parts. The panel is made up, broadly speaking, of 3 elements: 1) Profile, for example, an aluminium extruded one, which serves as an exterior rim; 2) Boards, for example, made of Calcium Silicate, Magnesium Oxide, Black Agglomerate cork, Glass, Fiber-cement or Plywood which will serve as permanent formwork and, simultaneously, the panel finish; 3) filling, for example, made of lightweight concrete, for example, combined with expanded polystyrene (tm) or hemp fibre and/or straw, filling with phosphogypsum or polyurethane foam. The profile 1) and boards 2) as a whole constitute a consistent, watertight mould which will contain the filling 3) until its solidification. This product leaves the factory ready for application (without the need for any additional finish).

It is possible to use polymeric fillings, preferably expandable, as they allow the greater adhesion and filling of spaces and a reduction in any slack between the parts of the panel. In the event that the polymeric filling is compression-resistant such as, for example, polyurethane foam, light panels are obtained which are highly stress-resistant which is particularly surprising if we bear in mind the resistance characteristics of the polymeric material itself compared with concrete. A polymeric filling should preferably be used which is intumescent, for example, intumescent polyurethane foam.

In the event that the boards (main faces of the panel) are glass, the filling may include embedded decorative elements or be pigmented in uniform fashion or with decorative patterns, for example, pigmented concrete. In addition, or alternatively, the filling may be transparent so as to allow the passage of light, e.g., polyethylene foam.

The profile, e.g. extruded in aluminium - central element of the differentiation of the solution and the technology - has a relevant feature: it is characterised by preferably having, throughout the external perimeter of the panel, a female cross section. This option allows greater freedom in terms of panel assembly. Alternatively, the profile/rim may have a female cross section, the recess for a slot, only on the two lateral faces of the panel, simplifying manufacture in those cases in which only the lateral affixation of the panels is required.

There is the use of a slot profile, a longitudinal part, e.g. a quadrangular tubular part whose thickness is variable in line with the mechanical requirements for binding between panels. The fact it is tubular also ensures that we can more freely pass technical cables inside the joints between panels as if it was a mini-cross section. Alternatively, the longitudinal part (s) of the slot may be solid.

The potential variety - of dimension and material - of the permanent formwork board, and filling thereof, allows giving different characteristics and qualitative levels to the different solutions obtained from the present disclosure - namely strength, robustness, lightness, low cost and ease of assembly.

The manufacturing of the panels by means of batteries which are also purpose-built to this end, the use of formwork reinforcements, namely on the permanent formwork boards and these reinforcements are only necessary until the partial curing of the filling of the panel.

The panels may be manufactured at the factory or in-situ, alongside the construction work, by means of mobile units.

The manufacturing process encompasses the following steps:

- having available the structural elements of the panel, possibly with the exception of one of the lateral or end faces, to facilitate filling by means of the respective opening (alternatively, a hole may be used on one of the faces which shall later be sealed);

- having available a formwork reinforcement, preferably in the form of a separator, namely on the permanent formwork boards as they are the largest faces; - filling of the interior space of the panel faces;

- where necessary, install the missing lateral or end face;

- wait for the total or partial curing of the filling;

- dismantle the formwork reinforcement separators;

- remove the panels.

The panels are preferably assembled vertically to receive the filling. Preferably, the panels are arranged in stacks which accumulate horizontally and are kept attached by means of compression.

The means of compression may be screws e.g. of the dywidag™ type, straps, hydraulic pistons or frames, suitable for maintaining the panels and their formwork boards under pressure until the filling has been sufficiently cured for the panels to be self-supporting.

The panels are filled by a filling system, individually (one by one) or in groups. If the panels are filled individually, the panels require individual reinforcements to avoid the breakage of the permanent formwork boards owing to the weight of the filling.

Separators may be used inside the battery which must be endowed with a high-relief whose thickness corresponds to the thickness of the aluminium profile. Its form must be such that it can be fit in between the unevenness of the exterior rim. The aim will be to ensure the position of the permanent formwork boards so as to avoid their breakage.

The separator may be just a sheet with thickness to offset the unevenness between the profile and the formwork board in the recess area to receive the formwork board. Preferably, the separator will have twice the thickness of the profile on the external part of said recess in such a way that one single separator is sufficient to install between two panels as the existing unevenness will be the accumulation of two unevenness zones. On the external faces of the top panels a sheet or separator may be used which preferably has the thickness of the profile on the external part of said recess so as to offset the aforementioned existing unevenness.

Alternatively, the separator may be strengthened, having on each of its faces unevenness to complement the attendant unevenness to be found between the profile and the formwork board in the recess area to receive the formwork board. Preferably, the unevenness will have the same thickness as the thickness of the profile on the external part of said recess. Preferably, the separator is strengthened in such a way that the filling of the panels can be carried out independently as the individual filling of a panel may cause any formwork boards to break which are not supported to withstand the weight of the filling itself. Self-evidently, if the panels are simultaneously or more or less simultaneously filled, this issue is not raised and the single separator may be used (51). The reinforced separator may comprise two sheets with said unevenness, containing in its interior a set of reinforcement bars or, alternatively, it may be a solid part.

The panels are preferably filled vertically. After the curing of the filling is sufficiently advanced for their movement, the panels are preferably rotated horizontally to be stacked up and transported.

It is disclosed a panel for wall or slab for dry construction comprising two main faces parallel between them, two end faces and two lateral faces, for leaning against or slotting into other panels,

wherein the main faces are each a permanent formwork board, and the lateral and end faces each have a constant cross section profile arranged longitudinally to each said lateral face forming a rim peripheral to the panel,

wherein said profile of the lateral faces comprises a slotting longitudinal recess for receiving one or more longitudinal parts for slotting into a slotting longitudinal recess of a lateral face of another said panel, and wherein the main, lateral and end faces define an interior region, said interior region comprising a filling obtained by depositing and curing on said permanent formwork boards.

Main faces are the name given to the two opposite faces with the largest area on the panel. The faces adjoining the main faces constitute a set of four faces which are peripheral to the main faces as the panel substantially has a parallelepiped shape.

Lateral faces is the name given to the faces that are arranged on the faces of the panel to lean against the panel or slot the panel into other panels. End faces is the name given to the faces of the panel that may, or may not, serve for leaning against the panel or slotting the panel into other panels.

The panel may be arranged horizontally, in other words, laid down, or vertically, in other words, standing up. If the panel is arranged vertically, the lateral faces may be on the left and right and the end faces above and below or the lateral faces may be above and below and the top faces on the left and right.

Detailed description

The present embodiments have the option of vertical application in the materialization of the walls, but also horizontally in the materialization of the flooring and roof boards, dispensing with the need for any other material - namely a finish - besides the primary structure which constitutes the structural skeleton of the constructions. These characteristics, as well as affording it great construction autonomy, ensure great cleanliness, thoroughness and organisation at the works' site, also deriving from its dry construction properties. Assembly and implementation at the works' site benefit from the extra lightness of said elements. It is worth noting that the present embodiments may dispense with the aforementioned primary structure which would be assumed in this case and namely in buildings with one or two storeys, by the panels themselves.

Figure la shows a sectional view of an embodiment of the panel (1). Figure lb shows a diagrammatic representation of a profile (2) of the panel. Figure lc shows a diagrammatic representation of the slot between two panels (1) and the slotting part (6).

Figure 2a shows an elevation view, for example, of an exterior wall of a building, of an embodiment of a structure which includes: panel assembled as a wall (11), supported on a panel assembled as a slab (12) which, in turn, is supported on a beam (4) which, in turn, is supported by columns (5). It should be noted that in this case the adaptor part was not used, as the slab (12), the beam (4) and the separation between the slab (12) and the beam (4) would not be visible from the exterior. Figure 2b displays a cross- section of the embodiment.

Figure 2c shows an external elevation view, for example, of an exterior wall of a building, of an embodiment of a structure which includes the panel assembled as a wall (11), being assembled internally on pillars (5). The adaptor part (3) was applied to this case. Figure 2d shows a cross-section of this embodiment.

Figure 2e shows an external elevation, for example, of an exterior wall of a building, of an embodiment of a structure which includes the panel (11) assembled as an exterior wall, being assembled outside the rest of the structure and optional interior panels. Figure 2f shows a cross-section of this embodiment, showing the simultaneous, but optional, assembly of panels (11) assembled as interior panels in accordance with embodiment 2a/2b above. The adaptor part (3) is also optional in this case. Figure 3 shows a sectional view of an embodiment of a structure with a panel assembled as a wall (11), a panel assembled as a slab (12), a beam (4) and an adaptor part (3) which, in turn, includes a skirting section (31), an upper support section (32) for the wall (11) as a panel, a vertical flashing section (33) for protecting the joint between the slab (12) and the beam (4) and the joint between the beam (4) and the wall (11) as a panel of the immediately lower storey in which the upper support section (32) includes a longitudinal protrusion to slot into the profile recess of said end face of the wall panel..

Figure 4 shows a sectional view of an embodiment of a structure as set out above in which the adaptor part (3) also includes a drip edge section (34).

Figure 5 shows a sectional view of an embodiment of a structure as set out above in which the adaptor part (3) also includes a lower support section (35) for the wall (11) on the panel in the immediately lower storey of the building and a ceiling trim section (36) in which the lower support section (35) includes a longitudinal protrusion to be slotted into the profile recess of the end face of the wall panel on the immediately lower storey of the building.

Figure 6 displays a Diagrammatic representation of the sectional view of an embodiment of a structure with the adaptor part (3) in which the lower support section (35) is only prolonged as far as the region of the longitudinal protrusion and, in particular, the longitudinal protrusion has a transversal width lower than the transversal width of the profile recess and a transversal depth equal to the transversal depth of the profile recess.

It is possible to obtain configurations on a curve by means of the juxtaposition of panels in small straight segments, namely using narrower modular configurations.

Figure 7 shows an image of an interior room carried out using slab and wall panels. Figure 8 shows an image of an interior room carried out using slab and wall panels.

Figure 9 shows an image of the exterior of a building carried out using slab and wall panels.

Figure 10 shows a battery image (stack) for filling with two panels subject to a reinforcement or compression structure and two separator versions (51, 52). The reinforcement or compression structure serves to avoid or break the filling boards owing to the weight of the filling until the curing occurs. Self-evidently, the filling battery may be a number of panels, with only two being represented in the figure for the sake of simplicity.

The single separator (51) of Figure 10a has a thickness to offset the unevenness to be found between the profile and the formwork board in the recess area to receive the formwork board. Preferably, between the panels the separator (51) will have twice the thickness of the profile on the external part of said recess in such a way that a single separator is sufficient to place between two panels. On the external faces of the end panels, the separator (53) shall preferentially be endowed with the thickness of the profile (it is no longer double thickness) on the external part of said recess.

The reinforced separator (52) of Figure 10b has, on each of its faces, an unevenness to complement the attendant unevenness to be found between the profile and the formwork board in the recess area to receive the formwork board. Preferably, the unevenness will have the same thickness as the thickness of the profile on the external part of said recess. Preferably, the separator is reinforced in such a way that the filling of the panels can be carried out independently as the individual filling of an individual panel may make those formwork boards break which are not supported to withstand the weight of the filling itself. Self-evidently, if the panels are filled simultaneously or almost simultaneously, this issue is not raised and the single separator may be used (51). In a complementary way to the embodiments above, the permanent formwork boards substantially extend over the whole lateral part of the profile, so that the panels present a uniform lateral face (see fig. 11, upper slotting) in this profile and slotting configuration. As an alternative, this profile and slotting configuration can be adequate to both permanent formwork boards. This profile and slotting configuration is particularly adequate to slabs formed by the panels of the present embodiments.

In a complementary way to the embodiments above, the profile (102a, 102b) can be executed in a material able to be sawed or cut, as for example wood, RPC or magnesium oxide. Figure 12 shows a sectional view of an embodiment of the panel (100), with a schematic representation of the main faces with permanent formwork boards (110), of the profile (102a, 102b) of the constant cross section arranged longitudinally on a lateral or end face, and the filling (120) cured on said permanent formwork boards (110). A cross section of the wood profile can be obtained from a single part or from the conjugation of three parts joined among them (as in Fig. 12). This conjugation, preferentially achievable in materials such as wood, or magnesium oxide, is composed, in an embodiment, of a part of a rectangular cross section whose larger dimension configures the profile width, and of two other parts, of substantially equal geometric dimension among them, which are fixed to the former by bonding or mechanical fastening at the opposed ends of the section of the latter (for instance, by screw, nail, staple, among others). The distance existing between these two equal parts establishes the recess dimension. These parts can, additionally, have a longitudinal groove (123) for the waterproofing element slotting, as in the remaining embodiments. The formwork boards can be fixed to the profile by bonding or mechanical fastening (for instance, by screw, nail, staple, among others).
