CZ186697A3 - Metallic frame for dry internal building up - Google Patents

Abstract

The frame has at least one preferably C-shaped stirrup firmly connected with it on its vertical section, supporting door hinges. One stirrup (11) is provided in the area of at least one, preferably several door hinges (5). The door hinges with their threaded bolts (7) extend to the stirrup and are preferably screwed to the frame and also the stirrup. Preferably, the stirrup in the area of its ends is connected to the frame by welding. The screw-in end of the threaded bolt (7) is formed as a thread cutter, and cuts a thread in the hole of the stirrup when the hinge is screwed into position.

Description

Technical field,

BACKGROUND OF THE INVENTION The invention relates to a metal frame for dry interior construction with at least one C-shaped, C-shaped, rigidly connected frame, which is provided on its vertical section and carries the door sticks.

Current_technologies

Frames that are fastened to masonry are normally completely rear filled with mortar or the like. In this case, the hinge mounting points extending from the frame level inwards to the masonry are completely surrounded and can easily absorb the weight of the door or the stresses generated by the forces when moving the two. ___ - -:::

Γ1.

DE-17 59 109 A discloses a plastic frame which is formed of two hollow bodies with a groove on the masonry side between them, wherein cores are inserted into the hollow bodies to reinforce the frame. The hinges are pushed through a bolt through one of the hollow bodies and its core up to the groove and there they are fastened by a nut. The frame is fastened to the masonry by means of brackets, which brackets are more or less held together in the region by connecting the bolts to the nut. On the side wall of masonry surround stirrups and connected thereto by means of examples of ^_ voltage spikes.

This fastening by means of the yokes is only preliminary and the frame, as can be seen from the drawing, is consequently normally without

- 2 gaps filled and the stirrups that are no longer needed are covered with plaster, thus eliminating the problem of introducing door forces into the frame and masonry. This dry frame is completely unsuitable for dry indoor construction.

The frames for dry interior construction mentioned at the beginning are similar to normal frames, but in their vertically arranged sections they usually have three stirrups which are connected, for example, bolted to vertically arranged C-shaped profiles, which hold the plasterboard from which they dry. the built-in inner walls essentially consist. These calipers are provided differently from the calipers in said file, since they do not enclose any masonry, but must rest on the ridges of the C-shaped profiles in order to be connected thereto. Since these brackets must fasten the frame not only during assembly, but must permanently carry it, they are connected to the frame firmly and permanently, especially by making the connections possible, but also releasable connections.

As a rule, construction is carried out by first fixing the C-shaped pillars, i.e., the posts, to the ceiling and the floor, then moving the frame into position and clamping it to the C-shaped profile with its brackets, then inserting the gypsum plasterboard. boards behind the level of the frame and ultimately are hardly screwed into the fixing points. The insertion thread is either made of frame material, but often the threaded sleeve is welded on the wall side, the sleeve having a threaded section and a centering extension provided on the wall side. This housing has a corresponding axial length.

The hinge mounting points are further provided in a normalized position at the frame level, but are surrounded by gypsum tone panels, usually at a distance. Increasingly, noise and noise reduction and fire protection for dry-erected interior walls are increasingly requiring the user and the manufacturer of such walls to be able to use doors with better sound-damping or fire prevention properties or other heavy loads in such situations. door.

In this case, due to the increasing weight of the door, mechanical problems occur because of the fixing points in the course of

In * W 'operation, they either release the level of the frame on which they are spot-welded, from the wall, or release from the level of the frame.

In both such cases, the door is initially difficult to move, then difficult to close normally and ultimately unusable.

Substance_of the invention

It is an object of the present invention to solve this problem.

The object is solved by providing one yoke in the region of at least one, preferably more door hinge, that this or these hinge hinges engage or extend with their threaded bolts or bolts. The brackets are preferably connected to the frame in the region of their ends, preferably welded. Thus, at least one yoke is provided at least in the region of at least one door hinge, but preferably in the region of at least two door hatches. These hinge bars extend with their threaded bolts up to the yoke and are fixed at both frame and yoke level. by screwing.

By means of this arrangement according to the invention, it is achieved that the door forces are introduced directly into a vertical C-shaped profile which holds a dry-built wall.

Frame level fastening serves to reinforce the assembled frame and keeps the frame level firmly on the gypsum board associated with it.

According to a preferred arrangement, all, as a rule, three brackets are arranged in the region of the fastening points and serve to fasten the other door masts as well. This further increases the strength.

According to another advantageous embodiment, a through hole is provided in the yoke and the tip of the bolt with the thread of the door hinge is thread-tapped. By means of this measure, the manufacturing cost of the frame according to the invention can be reduced to the cost of such conventional frames.

The invention is explained in more detail below on the basis of a preferred embodiment in conjunction with the drawing.

The figure shows a horizontal section through the frame arm that carries the door hinges in the region of one such door hinges.

An example of the invention

The metal frame 1 consists essentially of a profile 2 which is bent to a C-shape and into which a gasket 3 is inserted.

Fixing points 4 for door hinge 5 are provided in standardized areas. These door hinge 5 consists of a pivot (i, about whose axis a door (not shown) rotates) and a threaded bolt 7 which is screwed into a corresponding opposite thread of the respective fastening Places 4.

According to the invention, a bracket 11 is also provided in the region of the fastening point 4, which serves for mounting the frame J on a column 10 of dry-built walls 8. According to the prior art, the brackets 11 having only a slight axial length since many of the fastening points 4, as already mentioned, have such a large installation depth that it would be difficult to thread the gypsum board 9.

The yoke 11 has a substantially C-shaped shape and is joined to the frame 1 at its ends, preferably welded. The spine of this C-shape is facing the pillar 10 and connected to it, for example by means of screws.

The yoke 11 according to the invention and flush with the axis of the fastening point 4 has an opening in which the threaded bolt 2 forms a thread at its self-tapping end, which simultaneously serves to fasten the threaded bolt 7 to the yoke. In the frame T and in the yoke 11 and when screwing the door barriers 5, there is no need to take into account the position of the threads.

Thus, on the one hand, the door forces are introduced directly into the yoke 11 and hence into the C-shaped profile of the pillar 10 and, on the other hand, the stiffness of the frame 2 in the most stressed area of the door is substantially increased.

Significant simplification of assembly can be achieved if, as shown, the mounting point 4 in the direction of the masonry does not extend beyond the end of the outer profile of the frame 1, which is made possible by fastening the threaded bolt 7 in the yoke. and between the frame 1 and is drilled through the threaded bolt 7 when screwed in, but may be. also provided with a matching hole.

The invention is not limited to the illustrated embodiment, but may be varied in various ways. For example, other fastening means may be provided on the yoke 11, for example threaded sections or cage nuts. The invention can be applied to frames 1 of all dimensions and arrangements, if the frame 1 is not fastened to solid masonry but to columns, carriers or the like by means of brackets 11. These brackets 11 may also not have the shape shown but may be wing-shaped or otherwise as required by the installation situation.
