Load-bearing wall element and a method for forming a load-bearing corner pillar from wall elements

The invention relates to a load-bearing wall element according to the preamble of claim 1.

The invention also relates to a method for forming load-bearing corner pillars from wall elements according to the invention.

10 According to the prior art, construction methods are used in which factory-made non-load-bearing room elements are installed on the finished frame at the construction site. The disadvantage of this technique is that, firstly, the non-load-bearing elements break easily during transport and, secondly, they take up a lot of space during the transfer phase. In practice, the entire building cubic volume has to be transferred from the factory to the construction site at the highest cost.

The object of the present invention is to obviate the disadvantages of the prior art 20 and to provide a completely new wall element and a method for forming a load-bearing corner pillar from wall elements.

The invention is based on the fact that the wall elements are formed from outwardly opening C-profiles so that the outermost C-profiles of the element 25 are narrower and made of a thicker material than the C-profiles forming the actual wall. In addition, the profile depth of the outermost C-profiles is lower than the actual wall profiles. According to the method of the invention, the load-bearing corner pillars 30 are formed by welding the outermost C-profiles of two adjacent wall elements together.

More specifically, the load-bearing wall element according to the invention is characterized by what is set forth in the characterizing part of claim 35.

The method according to the invention, in turn, is characterized by what is set forth in the characterizing part of claim 5.

The invention provides considerable advantages.

By means of the invention, the steel plate-structured wall elements can be easily moved in a small space to the construction site itself. In addition, rooms made of load-bearing elements can be erected without a separate subframe. The invention also offers the possibility of quickly and reliably connecting wall and floor elements. In addition, the basic structure of the wall elements per se is suitable for the structure of the intermediate base elements 10.

The invention will now be examined in more detail with the aid of exemplary embodiments according to the accompanying figures.

Figure 11 shows a perspective view of a hotel room assembled from 10 elements according to the invention.

Figure 1 shows a horizontal section of a corner at the junction of two wall elements according to the invention. The individual wall element 1 consists of a corner part 2 and a wall part 6. The corner part 15 in turn consists of a vertical 3 to 4 mm steel plate C-cassette 3 with a profile depth of 40 mm. The width of the C-cassette 3 is typically about 100 to 200 mm, more preferably about 150 mm. Cassette 3 opens to the outer wall side. Insulating material 4 is installed inside the cassette and a fire protection plate 5 is installed on the inner wall side 20. The profile depth of the cassettes 3 is about 5-15, preferably about 10 mm smaller than the profile depth of the other cassettes 8 to allow installation of the fire protection plate 5. The wall part 6, on the other hand, consists of a plurality of vertically mounted steel sheet cassettes 8, the profile depth of which is suitably 50 to 60 mm. These cassettes also have a C-profile and open to the outer wall side. The width of the cassettes 8 is typically about 400 to 800 mm, preferably about 600 mm. A 13 mm gypsum board 7 is installed on the room-side wall of the wall element 1, and on the outer surface inside the profile 30 cassette insulation 9.

The two adjacent wall elements 1 are connected to each other by welding the steel plate cassettes 3 together so that the end side of the first cassette 3 joins the inner surface of the second cassette 3 35. In this case, the steel plate cassettes 3 form a load-bearing corner pillar.

According to Fig. 2, the partition wall of the two rooms B 9 61 7 4 consists of two wall elements 1, between which an additional insulating layer 11 is placed to improve the sound insulation. The steel sheet cassettes 8 of each wall element 1 are connected to each other by riveting. The joints 10 remain under the gypsum board 7 5. On the inner surfaces of the rooms there is still a fiberglass cloth attached to the surface of the gypsum board 7, which in turn is painted in the desired color.

According to Fig. 3, no additional insulation according to Fig. 2 is used in the partition wall 10 of the corridor and the room. Otherwise, the structure corresponds to the partition structure of two rooms.

According to Fig. 4, the outer wall element 48 consists of the base wall element 1 illustrated in Fig. 1 and an additional 100 mm insulator 40 placed on its outer surface 15 and a wind protection plate 41 placed on its outer surface. A collar 42 and an outer cladding are further placed on the outer surface.

According to Fig. 5, the corner parts 2 of the wall element form a load-bearing corner pillar, which can be fastened to the base profile 20, for example by welding, by fastening to the base profile of the intermediate layer of the next layer by means of lugs 52. The wide tab 52 of the cassette 3 is attached by welding to the outer surface of the cassette 3. The lug 52 is plate-like 25 and has a height approximately twice its width.

According to Figure 6, the wall elements 1 according to the invention are attached to the steel bottom circumferential profile 20 of the base element 36, for example by welding. The base circumferential profile 20 is formed of a 6 mm U-profile 24 which surrounds the base element 36 formed of a plurality of hollow core elements 21. The seams of the various hollow core elements 21 are filled with filler 23. The thickness of the hollow core elements 21 35 is typically 200 mm. The base element 36 is further coated with a leveling compound and finished with carpet 51 or some other suitable finishing material.

According to Fig. 7, the elements 1 and 36 of two adjacent rooms are connected to each other by means of a fastening plate 45 welded to the lower surface of the bottom circumferential profile 20. The mounting plate 45 is 6 mm thick and extends over the entire area to which the U-5 profile 24 on the lower surface of the base element 36 extends.

According to Fig. 8, the concrete slab 25 of the passage is supported on the bottom element 36 by means of a support slab 47 welded to the lower surface of the bottom circumferential profile. The aisle slab 25 is typically a 10,200 mm thick reinforced concrete slab. As shown in the figure, the aisle-room partition is completely on top of the base element 36.

According to Fig. 9, the outer wall element 48 according to Fig. 4 is connected to the upper base 26 by screwing the sheet metal cassette 8 of the edge 15 of the upper base 26 to the uncoated upper part of the outer wall element 48 with gypsum board 7. In addition to the interconnected sheet metal cassettes 8, the upper base 26 comprises cassette insulators 9 inside the cassettes 8 and an upper base insulator 27, which is suitably 300 mm thick blown wool. Both the cassettes 8 and their joints 10 can be realized by the same technique as the corresponding parts of the wall elements. Attached to the load-bearing corner portions of the exterior wall element 48 are brackets 49 for connecting the roof supports 28 to the exterior wall element 48. According to conventional technique, the lower surface of the water roof 30 has a wind protection plate 29.

According to Fig. 10, the midsole 31 consists of a base element 36 according to Fig. 6 and a sheet metal cassette plate 8 mounted below it, which corresponds to a cassette frame 30 of the upper base. The midsole 31 is mounted on the outer wall 48 between the wall elements 1 according to the invention. The actual fastening is done with a steel fastening plate 52, with which the load-bearing corner parts of the wall elements 35 are connected to the bottom circumferential profile 20 of the intermediate base 31.

According to Fig. 11, the finished room consists of a base element 8 5 61 7 6 36, and wall elements 1 attached to it. leaves a ready opening for HVAC bushings. In the solution of the figure, such an opening is left in the leftmost corner of the bathroom. According to the figure, the hollow core slabs 35 are covered with a leveling compound 50 and a finishing coating 51, such as a carpet, 10 parquet or a plastic mat. The corner parts 2 form load-bearing corner pillars and by means of the lugs 52 the intermediate base of the next layer can be attached to the corner pillars from its own bottom circumferential profile.

Although welding has been described above as a preferred fastening option, other fastening methods such as riveting, bolting, etc. may also be considered.
