Load-bearing room element structure as well as in the 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 thereto. The structure is difficult to manufacture and is not suitable for room construction that requires finished surfaces. In addition, the fixed connection of the elements to be superimposed on each other is slow and expensive with the presented solution.

The object of the present invention is to obviate the disadvantages of the prior art and to create a completely new load-bearing room element structure and a method for combining 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 element walls, 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-sections with a cross-section, the edges of which are turned inwards 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 connected on site without a separate subframe. The invention also makes it possible to connect wall and floor elements quickly and reliably. In addition, the solution according to the invention retains its load-bearing capacity even in fire situations for the period defined by the norms.

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

Figure 1 shows a horizontal section of a corner of a partition wall structure formed by two room 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 considered to be formed of a C-cassette opening in the direction of the room, which is 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 allow 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 outside of the outer wall. 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 inside the profile on the outer surface. If necessary, a fiberglass cloth is still 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 the movement of the 20 wall elements 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 formed inside the column 2, formed by the inner end 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 by bending, even when connected, to the extent that the corner joint can be threaded inside the column 2. In the figure, the outer wall structure with its thermal insulation and windscreens remains above the wall structure.

According to Fig. 2a, the corner column 2 is made of 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 Fig. 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 top of the column. The purpose of the steel plate 22 is to act as a support structure when connecting the columns 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 top of the steel frame 13 of the floor element. 15 cross-supports 11 and horizontal supports fixed between the upper ends of the pillars 2 are used to support the pillars 2. The columns 2 are fastened at the top with side brackets 19 to the frame of the next floor element and to the column of the next element.

According to Figure 4b, at the end of the room element, a V-support 15 is additionally used to support the element laterally. The V-support 15 is attached at the lower end substantially to the center of the steel frame 13 and at the top 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, as well as a frame 13 surrounding it. A coating 23 is placed between the frame 13 formed of the Z-profile and the hollow core slab 23. The coated 23 is also applied to the top of the slab 21. The thickness of the tiles 21 is suitably about 200 mm. The Z-profile 13 consists of horizontal upper and lower folds 24 and 30 and a vertical intermediate part 26 connecting them. The upper and lower folds are approximately equal in horizontal dimension, slightly larger than the width d of the pillars 2, i.e. approx. 50 mm. : The intermediate part 20, in turn, has a vertical dimension substantially equal to the thickness 9 'of the slab! 906 6 in size, ie approx. 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. Correspondingly, an L-profile 27 is used as a stiffener in the upper part of the wall element 6. The ceiling 29 is supported in place on the tongue 31 of the wall structure 6. The horizontal support

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. a joint 11a 35 of the horizontal supports 9. Insulation material 33 is arranged between the wall structures.

According to Figure 7, the joint 15 on the side of the two overlapping room elements is realized by side brackets 19 at the tops of the pillars 2, which are provided with a hole for the bolt mounting. 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 top of the column structure and as a fastening distance to the upper column 2 and 100 mm. As shown in more detail in Fig. 3, a steel plate with a thickness 20 of 10 mm is 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 out of the room.

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 outer 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 interior 43 walls 43. Sisåpååtyseinån 43 of the outer side should be finished in the whole voyage, as kåytåvån This implies surface to form a wall. Sisåpååtyseinån sisåpuolen 43 forms a part of the bathroom element, so viimeisteltyå seinåpintaa is not needed all the way.

10 As shown in 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 column 2 and the C-cassette opens out of 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 naturally does not 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 implemented as a retrofit plasterboard 47 with a thickness of 13 mm. A fire protection plate 45 with a thickness of suitably 10 mm is still installed between the gypsum board 47 and the column 2.

The solution of Fig. 12 differs from the solution of Fig. 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, except that the wall structure is pulled inwards, in which case the end cassette of the inner wall is located at the pillar stiffener 3 of the side wall.

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