Description

BACKGROUND OF THE INVENTION

This invention relates to a wall system frame assembly comprising substantially two types of metal sections, by means of which the walls of a building can be erected in a simple manner.

It is conventional to erect building walls of frame structures consisting of metal sections, which have been coupled together. However, in the past, it has not been possible to form a wall system without using a great number of different sections and utilizing special tools and machines. This in its turn, significantly increased the difficulty in transporting materials, as well as requiring relatively large staff of specially trained personnel. Consequently, the overall costs of forming the wall system tended to be exceedingly high.

The present, by comparison, renders it possible in a simple and work-saving manner to erect building wall systems which comprise a relatively few standardized elements.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A wall system frame assembly according to the present invention includes a first type of section, generally designated support section 1, and a second type of section generally designated connecting section 2. These sections can be complemented by third and fourth types of sections 3 and 4 respectively. The various types of sections comprising the preferred embodiment are each made of aluminium according a some conventional method.

The support section 1 has a substantially H-shaped configuration formed by two pairs of oppositely directed leg members which are provided with confronting leg surfaces having inwardly directed projections 5 formed on the ends thereof. Each support section 1 is further provided with at least one pair of parallel extending flange members on one outside portion and symmetrically positioned on either side of the section center of support section 1, which flanges support projections 6 directed inwardly toward each other. A web portion 7 of support section 1 is located about 10 mm from the section centre, and a pair of guide edges 8 are arranged about 10 mm on the opposite side of the section centre within the section.

Connecting section 2 has a substantially H-shaped configuration including two pairs of oppositely directed leg members of which opposed, outer leg surfaces formed with are provided with outwardly directed projections 9 in the form of hooks, which are countersunk slightly in relation to the lateral surfaces of connecting section 2. Connecting section 2 further includes a tongue-like locking section 10, which is drawn integral with connecting section 2 and is inclined inwardly to the section centre from a leg end on each side of the web portion 11 (FIG. 3). Owing to the design of the legs, an outer and an inner stop member 12 and 13, respectively, are formed in the respective leg end of section 2.

For a better understanding, the present invention is described in the following as the wall system can be imagined as being erected.

Support sections 1 are cut to predetermined lengths, and are mounted in pairs on parallel to the side of each other. Specific lengths 2 of the second type of connecting section 2 are positioned in suitably-spaced relationship and are attached by snapping between the support sections 1. In the preferred embodiment, the connecting sections 2' have a length of substantially 50 mm. Due to the fact that the projection 6 upon said snap-attachment of the connecting section 2' is located between the hook 9 and the outer stop member 12, the support section 1 is fixed relative to the connecting section 2'. In order to prevent unintentional inward bending of the legs of connecting section 2' after the mounting, and in order to frictionally lock connecting section 2' to support section 1, the tongue-like locking sections 10 are bent upward against the stop member 13 (FIG. 2). For the wall system now being erected, one support section 1 forms the outside of the wall and one further support section 1 forms the inside of the wall.

In order to support and attach the bottom support section or sill 1' (FIG. 1) to the wall system, preferably parts of a third type of section 3, which is generally designated as the attachment section, and which is fixed to the support section and ground 14 at equally spaced, intervals forming a row well leveled in height. This is carried out preferably so, that the fixing portion of the attachment section consists of a threaded metal rod 15, which is cast in the support (ground) and onto which a nut 16 has been screwed to desired levelled height on which rod is the section 3 rests. The shape of the section 3 is shown in FIG. 2 as including a substantially straight middle portion and a pair of L-shaped end portions attached to either end of the middle portion to provide good guidance in the lateral direction of the sill 1'. The sill further can be locked to the attachment section 3 by means of a plate 17 and nut 18, as shown in FIG. 2.

The mounting of upright support sections 1", which are comprised in the wall system and, like the sills 1' are formed of double support sections 1, is carried out in such a manner, that lengths 2" of the connecting section 2 are snappingly attached to the leg ends of the support section 1. Said lengths 2" of the connecting section 2 have in the preferred embodiment shown a length of substantially 20 mm and are attached by snapping in the places to be of the upright support sections 1". The uprights now are moved down over the connecting sections 2", so that these connecting sections are located in the space 19 of the particular support section 1 in question. The space 19, thus, is the one formed between the web portion 7 of the support section 1 and the pair of guide edges 8. The respective tongue-like locking section 10, which is easily accessible between the legs of the support section 1, is bent as stated previously for locking the lengths of connecting sections 22 to the sills 1'. The support section 1 and the lengths 2" of connecting section 2 also can be attached to each other by rivets.

The wall sheets 20 constituting the wall surfaces have such a width, that their edges extend in between the leg members of each of the opposed support sections 1 comprised in two uprights 1" positioned to the side of each other. The sheets 20 are mounted in the wall system by simply being moved down from above between the uprights and the support section leg members thereof before support sections 1 generally indicated by the horizontal girders 1'" of the same type as the sills and uprights are mounted. The sheets 20 are locked in a suitable manner to the sections, and the space between the sheets is filled with some type of insulation (not shown).

A horizontal girder 1'" or a horizontally attached window part 1.sup.IV are mounted as follows.

The horizontal girder 1'" or the horizontal window part 1.sup.IV consist, as mentioned before, of the parallel extending support sections 1, which are coupled together by means of specific lengths of the connecting section 2 having a length of substantially 50 mm. The girder or part is cut to a length corresponding to the distance between adjacently positioned upright support sections 1". At the ends of the support sections forming the girder 1'", the 20 mm long lengths 2" of the connecting sections 2 are inserted into the respective space 19, and the girder 1' is attached between the uprights 1". The lengths 2" of the connecting section 2 now are knocked or pressed against the uprights 1", so that the leg members of the connecting sections 2" snappingly engage with the inwardly directed projections 6 of the respective main section 1. After the girder has been finely adjusted, the locking sections 10 are knocked into locking position. The locking can be completed by riveting or screwing.

A window glass 21 (FIGS. 1 and 3) to be mounted between, for example, the window part 1.sup.IV and the girder 1'", is mounted as follows. The window glass 21, which is slightly wider but slightly smaller in height than the opening formed between the uprights 1" and the girder and, respectively, window part, is moved with one edge in between the legs in the intended support section for one upright 1", brought with the opposite edge into flushing alignment with the corresponding intermediate space between the leg members of the opposite upright 1", and is moved back some distance so that the two vertical edges of the window glass now are between the leg members of the respective support section. The window glass is thereafter lifted so that its upper edge is located between the section legs concerned in the girder 1'". A receiving section 4 with a length corresponding to that of the window part 1.sup.IV thereafter is laid on said part, and the window glass is lowered to rest on blocks 22 laid into the receiving section 4. The section 4 has such a height that with the glass resting on the blocks 22 the upper edge of the glass still is between the legs of the girder 1'". Suitable rubber strips 23 complete the mounting of the window glass 21. As appears from FIG. 3, the receiving section 4 has a substantially U-shaped configuration, the ends of the legs of which are designed in the same manner as the leg ends of the support section 1, so that a uniform type of mounting for the rubber strips 22 is obtained. The receiving section 4 further is provided with a pair of parallel extending guide flanges 24, which together with the projections 5 guide the receiving section 4 so as to prevent its lateral displacement relative to the support section 1.

It should have become apparent from the above description of the wall system according to the invention, that the system is of unique simplicity due to its extremely few parts, rendering the invention subject matter clearly superior to the known art.

The support section 1 also can be given the configuration as shown in FIG. 4, at which the guide edges 8 are replaced by an additional web portion 8'. On one side of the section, between the web portion 7 and the web portion 8', a part has been cut off, forming an opening through the respective leg members to permit access to the space 19 and to form projections 6.

The projections 5, which at this alternative have a simpler shape, and the projections 6 upon onhooking of the section 2 will be located between the hooks 9 and stop members 12 of said section.
