Load-bearing room element structure and method of combining elements

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

5

The invention also relates to a method for joining two overlapping room element structures according to the invention.

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 building-10 site. The disadvantage of this technique is that the non-load-bearing elements break easily during transport.

DE-A-1 953 657 discloses a transport container structure in which a load-bearing element 15 is formed by means of a complex bottom circumferential structure and L-pillars attached to it. The structure is cumbersome to manufacture and is not suitable for room construction that requires finished surfaces. In addition, the fixed solution of the elements to be superimposed is slow and expensive with the presented solution.

The object of the present invention is to eliminate the disadvantages of the prior art and to create a completely new load-bearing room element structure and a method for connecting two element structures.

The invention is based on the fact that the room element structure is formed by at least 25 wall elements formed by C-profiles opening outwards on three walls of the element, which are connected to each other at the corners and the corner joints are fitted inside the supporting corner pillars. The corner pillars are L-profiles with a cross-section, the edges of which are turned in like C-profiles. The corner posts have a smaller profile depth and are made of a thicker material than 30 C profiles,

According to the method of the invention, the overlapping elements are fastened to each other by supporting the lower element pillars via a support plate to the upper flange of the Z-profile of the upper element and connecting the lower pillars over the flange to the upper 91906 2 pillars by means of a fastener.

More specifically, the load-bearing room element structure according to the invention is characterized by what is set forth in the characterizing part of claim 1.

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, steel plate-structured wall elements can be easily moved in a small space at the element factory. In addition, the room elements can be combined on site without a separate subframe. The invention also offers the possibility of connecting the wall and floor elements to each other quickly and reliably. In addition, the solution according to the invention maintains its load-bearing capacity even in fire situations for the time defined by the norms.

The invention will now be examined in more detail with the aid of the exemplary embodiments according to the accompanying Figures 20.

Figure 1 shows a horizontal horizontal section of a partition wall structure formed by two element structures of a room 91 906 4 according to the invention. The wall structure 1 consists of a corner pillar 2 and a wall element 6. The corner pillar 2 can be thought of as formed by a C-cassette opening in the direction of the room and bent at an angle of 90 ° in the middle.

If necessary, an insulating material and a fire protection plate 5 with a thickness of suitably 10 mm are installed inside the column 2 on the inner wall side of the stiffener 3. The profile depth of the columns 2 is about 5 to 15, preferably about 10 mm smaller than the profile depth of the wall elements 6, in order to enable the installation of the fire protection plate 5. The wall element 6, on the other hand, consists of a plurality of vertically mounted steel sheet cassettes 8 mounted side by side, with a profile depth suitably of 50 to 60 mm. These cassettes are 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 if necessary cassette insulation on the outer surface inside the profile. If necessary, a fiberglass cloth is attached to the surface of the gypsum board 7 on the inner surfaces of the rooms 15, which in turn is painted to the desired color.

The wall elements 6 are not attached to the corner pillars 2, but can in principle move inside the pillars 2. As a result, small movements of the frame do not translate directly into movement of the wall elements 20 and thus the noise level is reduced. The C-cassettes 8 of the wall elements are in turn connected to each other, for example by riveting. The connection of the two wall elements 6 inside the column 2, formed by the end of the inner side of the first wall element 6 and the end of the second wall element 6, is realized in a corresponding manner before the connection is installed inside the column 2. This is possible because the lightweight wall elements 6 can be guided, even when joined together, to such an extent that the corner joint can be threaded inside the column 2. In the figure, the outer wall structure with its thermal insulation and windbreaks remains above the wall structure.

According to Figure 2a, the corner pillar 2 is a steel plate of 3 to 4 mm and with the C-cassette analogue 30 the profile depth d can be defined as 50 mm. The width k of the column 2 is typically about 120 to 180 mm, preferably about 150 mm. With the C-cassette analogue, the width of the unbent Οι cassette would naturally be about 300 mm. The width h of the stiffener 3 is in turn ti 91906 5 typically 25 to 35 mm, preferably about 30 mm.

According to Figure 2b, the height H of the column is about 2600 to 3000 mm, preferably about 2800 mm, depending on the desired room height.

According to Figure 3a, a steel plate 22 in the shape of the outer cross-section of the column 2, which is suitably about 10 mm thick, is welded to the end of the column. The purpose of the steel plate 22 is to act as a support structure when connecting the column 2 to the floor structures. According to Figures 3b and 3c, the outer edge of the column 2 is chamfered in order to keep the weld seam 10 between the column 2 and the steel plate as level as possible with the surface of the structure.

According to Fig. 4a, the supporting frame of the room element consists of pillars 2 welded on the steel frame 13 of the floor element 13. Cross supports 11 and horizontal supports fixed between the upper ends of the pillars 2 are used to support the pillars 2. The pillars 2 are fastened at their upper end with side brackets 19 to the frame of the next floor element and to the column of the next element.

According to Figure 4b, a V-support is further used at the end of the room element to support the element laterally. The V-support 15 is fixed at its lower end substantially in the middle of the steel frame 13 and the upper ends to the middle stages of the pillars 2, respectively. The end brackets at the ends of the columns 2 are slightly larger than the side brackets 19 shown in Figure 4a.

According to Figure 5, the floor element consists of one or more hollow core slabs 21 and a surrounding frame 13. A coating 23 is placed between the Z-profile frame 13 and the hollow core slab. The coating 23 is also applied to the top surface of the slab 21 in a suitable layer of about 25 mm. The thickness of the tiles 21 is suitably about 200 mm. The Z-profile 13 consists of horizontal upper and lower folds 20 and 30 vertical intermediate parts 26 connecting them. : The intermediate part 20, on the other hand, has a vertical dimension substantially equal to the thickness of the slab 91 9 G 6 6, i.e. about 200 mm high. The lower fold 20 of the Z-profile of the frame 13 folds under the plate 21 and the upper fold 24 away from the plate 21. The upper fold 24 of the Z-profile is used as a planar surface on which the column structures 2 and the wall elements 6 rest. The outer edge of the upper fold 24 extends to the same level as the outer surface of the pillars 2. The wall elements 6 are supported at their lower part by L-profiles 25 on the upper flange 24 of the Z-profile 24. Correspondingly, an L-profile 27 is used as a stiffener in the upper part of the wall element 6. The suspended ceiling 29 is supported

The structure according to Figure 6 consists in principle of the structure according to Figure 5, which is connected to its mirror image. The structures are supported by each other e.g. with the connection 35 of the horizontal supports 9. An insulating material 33 is traced between the wall structures.

According to Fig. 7, the joint 15 on the side of two overlapping room elements is realized by side fasteners 19 at the upper ends of the pillars 2, which are provided with a hole for bolt fastening. The thickness of the Z-profile 13 is suitably 6 mm. The side bracket 19 is preferably fastened at a distance of 50 mm to the upper end of the column structure and the fastening distance to the upper column 2 remains 100 mm. As shown in more detail in Figure 3, a steel plate with a thickness of 20 mm is suitably left between the Z-profile 13 and the lower pillar 2. The dimensions of the side bracket (width x height x depth) are thus suitably 100 x 166 x 5 mm3.

According to Fig. 8, the end connection of the element is otherwise corresponding to the side connection, except that the end bracket 17 is provided with holes for two bolts and in addition the portion extending to the upper 25 pillars 2 is 60 mm longer.

According to Fig. 9, the fastening of the brackets 17 and 19 to the column 17 is carried out with a bolt of, for example, type M16X30.

As shown in Figure 10, the room element typically consists of two side walls 39, an outer end wall 41 and an inner end wall. With the exception of the inner end wall 43, the wall structures are formed of C-cassettes that open away from the room space.

Il 7 919G6 In this way, a flat surface is obtained in the direction of the room, to which it is easy to attach, for example, gypsum board. Either another corresponding element or an external wall element is installed outside the side walls, so the surface does not have to be finished. On the other side of the outer end wall 41 there is always an outer wall element. The situation is different for the inner end-5 wall 43. The inner end wall 43 of the outer side should be finished in the whole voyage, since this surface forms a channel wall. The inner end wall 43 forms a part of the inside of the bathroom element, so to finish the wall surface does not need the whole length.

According to Fig. 11, the bathroom corner of the room element is designed so that the C-cassette of the side wall 39 normally extends inside the pillar 2 and the C-cassette opens away from the room. On the side of the inner end wall 43, in turn, the finished surface is formed on the side of the outer wall, and the C-cassette 8 opens in the direction of the room. In this case, the C-cassette does not naturally enter the column structure, but rests on the side surface of the column 2 15. The outer surface of the inner end wall 43 is realized as a retrofit of gypsum board 47 with a thickness of 13 mm. A fire protection plate 45 with a thickness of suitably 10 mm is also installed between the gypsum board 47 and the column 2.

The solution of Figure 12 differs from the solution of Figure 11 in the implementation of the inner surface 20 of the inner end wall 43. The inner surface of the inner end wall 43 is in principle implemented in the same way as the side walls, with the exception that the wall structure is pulled inwards, whereby the end cassette of the inner wall falls on the side wall column stiffener 3.

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