In many types of buildings, such as conference apartments, sports halls and the like, so-called rows of windows or window walls consisting of parallel pipe columns and their supporting, frameless glass parts, usually multilayer panes, which cannot be opened. The glass parts are fastened to the columns by means of strips, and in order to prevent the passage of heat, members of heat-insulating material are arranged between the glass parts, whereby these members form a fastening between the strips and the columns.

The pipe columns are provided on one side on both sides with a rear breadth, a longitudinal gutter with a base dimension larger than the opening of the jewelery. The insulating members comprise a foot arranged to fit said trough and a block of substantially uniform thickness protruding from the foot, which along its longitudinal side surfaces has a groove for the mounting bracket.

Embodiments of this type used heretofore have required a great deal of fitting work, and it is an object of the present invention to provide such an embodiment of the components in question that the installation work is considerably reduced.

2,59846

The invention is characterized in that the protruding member has the shape of a substantially uniform block, and that the bottom surface of the foot is formed substantially as a parallelogram with a distance between sides parallel to the sidewalls of the block approximately equal to the bottom of the gutter and substantially equal to the other two sides of the parallelogram. than the width of the gutter opening.

The leg is rounded at the obtuse corners of the trapezoid with the intention of making it easier to turn the leg to secure it to the chute.

The side walls of the block are best provided with at least two pairs of grooves located on different levels, so that glass sections of different thicknesses can be handled in a simple manner, e.g. triple and double glazing panes, respectively.

The invention is described below by way of example with reference to the accompanying drawing.

Figure 1 shows a cross-section of a pipe column with an insulating member under installation.

Figure 2 shows a top view of the detail of Figure 1.

Figure 3 shows a cross-section of a pipe column in which the glass parts are mounted.

Fig. 4 shows a view similar to Fig. 2, but with the insulating member turned to the correct position for receiving the glass parts, i.e. in the same position as in Fig. 3.

Window walls of the type referred to herein are well known and need not be described. They comprise a series of vertical, sometimes somewhat inclined, columns extending from the top to the bottom of the window opening and supporting fixed glass sections which are attached to the columns by means of strips which are screwed or clicked onto the columns. At large spans, in this type of structure, columns and moldings usually have to be made of metallic, usually light metal, and then very precise must be made so that any direct metallic contact between the outside of the wall and its inside is avoided. Otherwise, high heat losses and also the risk of compaction run-off, or ice formation on the inside of the columns, are obtained.

These so-called in order to avoid cold bridges, members of insulating material have been used, which are first attached to the columns and to which 3,59846 the glass-fixing strips are then attached, usually by means of screws.

According to the invention, columns and insulating members are now formed in such a way that they can be attached to the columns later, without the use of pre-drilling or other fitting work, and then the strips to the insulating members, also without much fitting work.

The columns consist of metal tubes of square or rectangular cross-section and are provided with a longitudinally extending trough 11 on the other, outwardly pivoting side. This is double-sided back-cut so as to have the shape of a roughly lying C. Parallel to and outside the chute, there are grooves for the seals 13 (see Figure 3).

There are a plurality of thermally insulating members in each column - comprising a leg 14 formed to fit in the chute 11 and a substantially uniformly thick block 15 protruding from the leg.

Figures 1 and 2 show the member in the first step when it is mounted on a column. The leg 14 has a bottom surface formed essentially as a parallelogram, where the distance between the sides 17 parallel to the side walls 16 of the block is approximately equal to the bottom dimension of the trough 11.

The distance between the two other sides 18 of the parallelogram is substantially equal to the width b of the opening of the trough 11. The member can then, as shown in Figure 2, push the sides 18 into the trough 11 parallel to the tongue opening walls and can then be turned approximately 45 °. securely attached to the chute. To facilitate this turning, the leg 14 is rounded at the obtuse angles 19 of the trapezoid. The leg 14 is further formed in a stepped manner so that a part of its upper side is cut off along each side 17. The distance between the upper steps 17a is equal to dimension b, and here too the obtuse corners are rounded. The thickness of the foot inside the sides 17a corresponds to the depth of the trough 11.

The glass parts 20 are then placed against the seals 13, in the form of three-pane insulating panes, as shown in Fig. 3, and it is self-evident that the respective seals are along the upper and lower horizontal frame parts of the window opening. The glass parts extend almost to the block 15, and seals 21 are placed on the outer 4,59846 glass surfaces.

The block 15 is provided with longitudinally extending grooves 22 in its parallel side walls for co-operation with a strip 23 which fastens the glass parts to the column. The strip 23 is provided with flanges 24 pivotable towards the column, which in the installed position surround the top of the block and are provided with strips 25 for co-operation with the grooves 22.

This strip can be snapped onto the blocks or pushed in the longitudinal direction of the column so as to obtain the desired adhesion between the strips 25 and the grooves 22.

The block is provided with two pairs of grooves so that double-glazed insulating panes or otherwise made glass sections with a smaller thickness can be used with the same components.

This installation can take place completely without tools, and it is clear that the finished structure lacks completely through-going, metal parts.

The strip 23 does not have to be continuous in the longitudinal direction of the column, but is sufficient in the form of shorter pieces which are mounted on top of each block. These short strip pieces can be glued or nailed to the blocks.

The strip pieces 23 are provided with two outwardly directed flanges 26, on which the cover strip 27 can be snapped onto in a known manner.
