Abstract

Wall element, for use in buildings, incorporates a frame composed of four layers arranged symmetrically to the element's centre plane, shaped for mutual form locking connection with the edge of an adjacent similar element; the two middle layers of the four are also present inside the frame. Each of these two middle layers is made up from strips running vertically, spaced so that the strips of one middle layer seal the intervals between those of the other layer, with an edge overlap. By this means space is provided in the interior for the optional introduction of servicing ducts from both sides, and this can be effected on site, if necessary.

Description

The invention relates to a wall element for buildings with a frame of four to the wall element center plane symmetrically arranged layers, soft due to mutual offset the form fit with Form a narrow side provided for a neighboring element and of which the two middle layers also are present inside the frame.

A similar wall element according to DT-AS 17 84 623, in which a middle layer inside the frame is drawn through has the major disadvantage that the drawn through middle layer allows the attachment of lines inside the elements is a hindrance and the attachment of such lines only on one side Allowed to pass lines from one side to the other or to allow of inserting lines of larger cross-section strips removed from such a middle layer, so the element loses part of its static strength.

In the case of wall elements made up of layers, intermediate layers are often missing, so that for fastening of installation lines only the cover layers are available and therefore during the prefabrication of the Elements the lines have to be fixed before the element is closed. So you can Do not freely dispose of the elements when building, but must designate the line-supporting elements and install in certain places. An arrangement according to the magazine »Building Materials ”, Issue 4/1960, p. 122, with the special cable ducts between the otherwise cable-free elements must be provided. For elements with no middle layer, according to the magazine »Building Materials Export ”from December 1961, p. 115, there are also specially perforated vertical bars in the holes if necessary inserted horizontal beams proposed as anchoring points of lines which, however, also requires the routing of the cables to be taken into account when manufacturing the elements. In In all of these cases, subsequent installation of the line on the construction site is hardly possible or only with a very large amount Effort possible.

For other elements in layer construction, e.g. B. according to DT-Gbm 18 51355 leave the middle Layers no rooms suitable for lines open.

There have there, for example diagonal struts like. T Ih.rpnnt be what statically not permissible and around-SÄeÄnderungendes assembly of the elements are not possible on the building or insufficient

'"Sir invention has for its object to provide a wall element of the type mentioned, the bending in the interior space for de optionally be.dsem- ° attachment of cables to the central layer

_n fet and the line assembly is permitted not only in the element factory but also on the construction site.

^{D: 1} se object is achieved according to the invention in that in a wall member of the genannten'Art initially Every of the two center layers of film strips, soft in the vertical direction at a distance next to each other so extend that de Sch.chtstreifen of a middle layer, the distances between the Seal the layer strips of the other middle layer by overlapping the edges.

It is possible to use cables of certain cross-sections on the construction site or during the prefabrication into the distances between the individual layer strips on both sides of the middle level of a To accommodate the element, so that the problem of

Passing through the layer is solved. because one each line can be attached to the side on which it is ultimately intended to flow. . ".- ,,

Although one should have expected the benefits of the invention at least by an increased material

It has been shown that on average this is not the case for the middle class applies but even save a lot of material compared to a roughly equally solid construction

can. ",

So you can while maintaining all the structural advantages of previous corresponding elements in addition a plus in static properties and advantages in terms of the feasibility of lines either Save material or at most require the same amount of material.

If one also takes into account that the structure of the middle layer in the invention is very simple can go on, there is also an advantage in terms of work technology, because at the points of overlap no absolute precision is required, as was previously the case at the butt joints or at Tongue and groove was the case.

Since none of the middle layers goes completely through, but rather each is interrupted, the outer Maintain the dimensional precision of each element without the same absolute precision being required inside.

The invention is described below with reference to the drawing, for example. It shows

F i g. 1 shows a schematic horizontal section with a diagrammatically connected part of an inventive Wall element and

F i g. FIG. 2 shows a view, broken twice, of an element according to FIG. 1.

The frame 1 of the element is made up of the four layers 10, 11, 12 and 13, which are arranged symmetrically in area to the center plane ME of the element. By offsetting these frame layers, positive connection points to neighboring elements can be created.

In Fig. 2 only the layers 10 and 12 of the frame 1 are visible.

The two middle layers 12 and 13 also extend inside the frame 1. It can be seen in front

fr

particularly in Fig. 1. that the layers are built up 12 and 13 from single layer strip 120, 120a and 120 ', 121, 121a, 121 b and 121'.

The individual layer strips belonging to the same layer 12 or 13 are arranged at a distance from one another, the layer sires 120, 120a and 120 'of the middle layer 12 closing the distances between the layer strips 121, 121a, 1216, 12Γ of the middle layer 13 with edge overlap . Lines Ll, L 2, L 2 'and L 3 thus find Matz on both sides of the middle layers 12 and 13.

In the case of conventional elements with the same frame structure, only one of the two central shafts and this without interruption have been provided inside the element so that for lines such as L 1 in FIG. 1 was only on one side of the ME center plane. This meant that lines opening out on the other side could only be passed over after the middle class had broken through. In contrast, with the wall element according to the invention, the line belonging to one side can already be used

ίο arrange in advance on the correct side, such as the z. B. with line L 1 or L 2, L 2 'in F i g. 1 can be seen.
