BACKGROUND ART There are different types of buildings in the above-mentioned technical field, which are easy to handle and haul, and are described in SE-B-426 253, US-A-3 1 ? 3 186 as well as EP-0-506 502.

Removable buildings often has a metal frame construction, which is made of steel profiles, which are welded together to obtain the fame work of the building. Sheets are subsequently welded to this construction all around and doors and other openings are made, depending on what the building will be used for. The floor often is made of thick sheets and the entire construction must be welded together by means of a plurality of welding points.

These buildings are expensive to produce, the material costs being high and also, a lot of work is required to produce them and a great proficiency is required of the people producing these buildings. Also, special tools are required to produce the buildings. Also, they are difficult to handle, because they are heavy and bulky. The hauling and the packing of these turn key buildings are often expensive, problem-ridden moments and increase the cost of the delivery to the final erection site, located in any part of the world. Also, these transports constitute environmental hazards, since large amounts of fuel are required to carry these buildings to all parts of the world.

Also, it is difficult, when using this technique, to obtain an aestheticly attractive building at a cheap rate, since it is necessary to fasten the sheets either at the outer or the inner side of the frame. Insulation and other special building measures often are required in order to obtain a functioning building and these toils are very time-consuming and consequently expensive to carry out.

The flexibility as regards the production technique is also limited with this known technique and custom-made solutions are often required to meet the requirements of the purchaser as to outer and inner design as well as the requirements of the purchaser as to a stable and functioning building. This means, that the cost estimates of producing the buildings will not be satisfactory as regards the production costs in the factory.

When a kit of already known constructions is delivered to a site in a certain country, there often are, exactly at that site, neither the required tools nor the required proficiency and expertise necessary to carry out the welding, the erection and the mounting in a completely satisfactory way.

BRIEF DESCRIPTION OF THE INVENTION The object of the present invention is to eliminate the above-mentioned drawbacks with the production of buildings, particularly designed for accomodating technical plants having a substantial weight.

A main object of the invention is to produce a building, which despite a light weight construction is able to support heavy loads on floors and walls as well as to resist high stresses arising due to wind, snow, rain, cold and heat loads.

Another object of the invention is to produce a building, which it is easy to transport and handle, either as a turn key building or as a so called flat pack, i. e. packed as flat building section parts.

An additional object of the invention is to produce a building at a low cost, which has a high quality and satisfactory finish. strength and stability also being obtained.

Another object of the invention is to produce a building, which it is easy to quickly modify depending on the requirements.

An additional object of the invention is to produce a building, which can be handled by means of a truck without extra loading measures as well as can be easily lifted by means of a crane without a lot of fuss.

One object of the invention is to produce a building, which it is easy to EMC-suppress by means of guiding lists in all the joints between the building elements.

An additional object of the invention is to produce a building, which can be erected on feets and which consequently can be erected without having to carry out any particular foundation work.

Another object of the invention is to be able to transport the building without or with a minimum of packing measures and materials without subjecting the building to damages or serious scrapings, since it can be easily packed and transported in an ISO standard container, either as a turn key building or as a"flat pack".

In accordance with the inventive idea the above-mentioned problems are solved by mounting corner angle profiles at the corners of the building, the angular legs of the corner angle profiles being fastened to the walls, as well as the entire weight of the building being received at its corners by means of surfaces, fastened to the lower ends of the corner angle profiles a short distance from the lowermost edge of the comer angle profiles, and the corner angle profiles extending along substantially the entire height of the walls.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION In Fig. 1 an embodiment of the invention is shown in perspective, namely a building 1 having a roof 2 as well as walls 3,4,5,6 and a floor 7, short side 3 having a door opening 8. Walls 3,4,5,6 and floor 9 comprise frame structures 10, each comprising crossbars 11 made of wood, plastic, metal or any other suitable material, the hollow spaces in the frame structures 10 being filled with a relatively thick insulating material, preferably an extruded polystyrene, functioning as an insulating core 15, as well as at each side of this material an outer 13 and an inner 14 relatively thin layer of suitable materials, preferably metals and/or plywood, being fastened to frame structure 10 by means of eg. screws, nails or rivets in order to obtain sandwich laminated building panel elements 12. Walls 3,4,5,6 and floor 9 are joined together and subsequently corner angle profiles or irons 20 are mounted along corners 16,17,18,19 of building 1 by fastening them to those walls 3,4,5,6, which are positioned adjacent each other along the respective comers 16,17, 18,19, roof 2 subsequently being mounted. AD this can be done either in a factory or the parts of the building can be packed up, being provided with fittings and fastening materials, e. g. screws, fittings and possibly simple hand tools, designed for the construction of the building at its site, into a so called flat pack to be hauled to the site. Corner angle irons 20 each one has two surfaces 23,24 at its lowermost end 22, which are fastened at right angles to the longitudinal direction of the corner angle profiles and extend to a position below the building. Surface 23 is positioned a small distance upwards from lowermost end 22 of the corner angle profile and is designed to receive the respective corners 16,17,18,19 of building 1, and surface 24 is positioned along lower edge 25 of corner angle profile 20 and is designed to, jointly with lowermost end 22 of each corner angle profile 20, constitute erection feet 26 of the building.

Building 1 will be particularly stable, easy to lift, easy to handle and haul due to the combination of the substantial sheet stiffness and the small weight of building panel elements 12 and the strength and design of the corner angle profiles 20, the corner loads of building 1 being received on surfaces 23, positioned a distance from lowermost end 22 of corner angle profiles 20.

The dimensions of floor 7 are roughly the same as the inner dimensions of building 1, lower edge 27 of floor 9 being positioned along lower edges 28,29,30,31 of the respective walls 3,4,5,6.

Fig. 2 shows an embodiment of a corner of the building seen in cross-section and from above. It is shown, how corner angle profile 20 is fastened by means of screws 32,33 to outer sides 13 of building panel sheets 12, as well as how a screw 34 holds together wall frames 10. Surface 23, which receives the corner loads of building 1 and is shown with dashed lines, extends to a position below the building.

Fig. 3 shows corner angle profile 20 with holes 34 for screws 32, 33 as well as a larger hole 35 with threads, designed for a removable fastening of a fitting, designed for lifting the entire building, e. g. by using a crane, which fitting is easy to remove, when the building finally has been erected, and it is also easy to mount it again later, in case it is necessary to lift the building, e. g. when it is to be moved.

Fig. 4 shows a cross-section along line A-A in Fig. 3. Surface 24 is fastened by means of e. g. welding to lower ends 22 of corner angle profiles 20 and constitutes erection feet 26 of the building and extends from the corners of corner angle profile 20 to a position below building 1.

Fig. 5 shows a cross-section along line B-B i Fig. 3. Surface 23 is in the same way as surface 24 fastened e. g. by means of welding to corner angle profiles 20 but positioned at a certain distance upwards from their lower ends 22 and extends from the corners of corner angle profiles 20 to a position below the building 1.

Fig. 6 shows an embodiment of surfaces 23,24, designed to receive the comers of the building as well as the foot of the building. These surfaces 23,24 consist of the upper and the lower surface of a part 28, similar to a square tube, which part is fastened to lower part 22 of the corner angle profile. This part 28, similar to a square tube, is in this case obtained by welding two similar parts together and is used as stable platforms for the corner loads of building 1 and efficient erection feet 26 for building 1.

Fig. 7 shows, how a building according to the invention can be lifted e. g. by means of a crane using the fittings, mounted in holes 35 in the upper ends of corner angle profiles 20.

Fig. 8 shows, how an additional floor frame 39, made of metal, e. g. aluminum or the like, can be mounted below the sandwich laminated building element, which is used as floor 7, when exceptionally heavy floor loads are present. They will in this way reinforce the construction of the building via the corner angle profiles and their surfaces 23.

Fig. 9 shows a cross-section of an ISO standard container and how two buildings 1 according to the invention can be placed in it and be hauled, no packing means but the container being required.

Fig. 10 shows a longitudinal cross-section of an ISO standard container and how six flat packs of the parts included in the invention are accommodated in such a container. Lifting points 40 are arranged on additional frame 39 on each side of the center of the long side or the short side, to be able to handle building 1 by means of a crane.

Since the building according to the invention consists of a small amount of parts, it is easy to make holes in the floor, the walls and the roof and furthermore only two persons are able to easily and quickly erect the building by using simple hand tools.

Intergated erection prevent pressure damages from below and the buildings is so protected against moisture damage from below.

The sanwich panels are in their standard design made of two galvanized and painted sheets of steel, an insulating core being inserted between said sheets, the core being made of e. g. self-extinguishing extruded polystyrene, EPC. Various types of panel materials can be used.

All the joining surfaces are sealed against dust and moisture, when the sandwich panels are mounted. Also, the roof panels are sealed by using an additional outer sealing compound.

The wall and roof panels can be color adjusted and be provided with outer decorative panels, made of various materials and having a special layout.

The building can be handled by a lifting truck from the long sides as well as the short sides.

The invention can of course be modified in many different ways within the frame work of the inventive idea. defined by the enclosed claims.
