Description

The invention relates to wall elements as load-bearing, plate-like parts of a limited space for the creation of repeatable prefabricated buildings, equipped and designed with means integrated at least partially in the plates for connection or coupling with further wall plates of the same or similar design, the parts for connecting or Coupling required recesses in the wall plates limited to the supporting parts and covered by any insulating layer and here the wall plates are rectangular and arranged vertically, the connection of intersecting intermediate wall plate combinations by two each formed at the crossing connection point of the interlocking or overlapping, mirror image Recesses are made in the joints of the two intermediate wall panel combinations, and the wall panels are preferably made of a reinforced concrete layer and a, generally outwardly insulating layer exist. The Belgian patent BE-A-852817 discloses a method for producing prefabricated buildings by putting individual panels together.

This method has the disadvantage of plug-in slots extending over half the height of the board, one slot engaging from above and the other from below into the pair of boards to be connected.

The intended depth of these slots means that when joining a corner joint, the upper plate must be raised over half the height of the lower plate in order to allow the slots to be joined. The same difficulties are naturally also present during dismantling, so that the use of these elements requires the use of additional lifting means.

Regarding the system of this training, it should be noted from a static point of view that the stopping point is moved approximately in the middle of the height of the wall plate and thus there is clearly an increased risk of tipping, at least during assembly or disassembly. In this case, it must be expected that there is a risk of a breakout in the direction of the plate boundary for the overlapping plate if it is tilted.

US-A-3 962 839, which is based on DE-A-2 338 390 (both Ickes), relates to wall elements which, in the area of their upper horizontal boundary, are covered by overlapping or engaging, vertically directed recesses or recesses open on both sides and / or approaches with other, correspondingly designed wall elements are pluggable detachable or joinable.

The only assembled plates - z. B. 14, 14 'and perpendicular to this 15 - in connection with the high weight of these plates can be described as quite satisfactory, although it is assumed that subsidence or foundation - z. B. also earthquakes - are not always fully absorbable. The assembly and disassembly require great care because the recesses can be damaged or destroyed by tilting.

The French script, CAHIER DU CSTB, No. 97, F 3 1969 indicates a system which has the connection of two panels in the same direction with the connection of an intermediate wall branching perpendicularly from it. The criterion of this training is that the rectified slabs have reinforcements that protrude into a free space in the joint area, which additionally receives an anchor from the slabs arranged perpendicular to it, and then the free space is again filled with concrete. The connection thus produced has the disadvantage of being unsolvable, so that disassembly requires at least the partial destruction of this assembly.

To summarize the concerns and disadvantages of the prior art, it is the object of this invention

Wall elements, d. H. To name wall panels according to the type described at the outset, which are suitable for forming a limited space which can also be expanded by further cells, without the necessity of using, in particular, adhesive or hydraulic binders, and in which the necessary recesses are arranged in the upper region of the wall panels themselves and these are limited to a minimum, whereby the height of the wall panels should correspond to the floor height.

The solution to this problem according to the invention provides
that the directional, outwardly flush butt joint of two wall plates is carried out together with the intermediate wall plate, which is arranged at right angles between the joint, by easily detachable coupling means which engage in a holder of this plate pointing upwards from the recess and project laterally from the two wall plates,
that the directional butt joint of two wall panels directed perpendicular to the first-mentioned wall panels, together with the butt-standing intermediate wall panel assigned vertically to the joint of these wall panels, is achieved by easily detachable coupling means engaging in a free space, projecting laterally from the intermediate wall panel, the free space being provided in both identical recesses arranged in mirror image to one another in the wall panels are formed with upward-pointing brackets,
that the wall plate and that of this rectangular the upstanding wall plate of the two pairs of wall plates of the same direction form a corner connection, and this is achieved by an easily detachable coupling means which projects out of the recess of the plate and which protrudes laterally from the wall plate, and that coupling means are arranged exclusively in the upper corner region of the wall plates and that after Recesses open at the top and to the sides in the case of non-intersecting wall panels are only arranged in wall panels in one direction at the connection points.

Finally, as mentioned in relation to the main features of the invention, the required recesses to be provided in the outer wall panels are located in the upper horizontal corner regions of these panels and are opened towards the vertical.

As a rule, the open area of the load-bearing layer is covered to the outside by the insulating layer according to the preamble, so that the composite is flat on the outside.

Furthermore, this means that the composite formed from the wall panels is connected only in the region of its upper limit by releasable coupling means.

In addition to the connections between two at least identical wall plates of the same type, which provide an arrangement of the intermediate wall plate to be connected at right angles between the two outer wall plates by releasable coupling means arranged in the recesses, a further form of connection of such an intermediate wall directed perpendicular to two wall plates is provided. In this case, in the joint area of the two wall panels standing against each other, in the upper corners, a mirror-image-shaped recess is provided, which together with the other forms a uniform free space.

A partition wall plate is arranged perpendicular to this joint, into which the releasably connectable coupling means projecting from the three plates.

The design of the corner connection from the insulated wall panels usually to be referred to as outer wall panels or the wall panel combinations formed therefrom provides that one panel of the wall panels which are assigned at right angles to one another is flush with the top of the other panel. In the other plate, which is assigned to the head side of this plate at right angles, a recess is provided, in the free space of which the coupling means connected to the two plates are arranged so as to be releasably releasable to one another.

In this connection it may be important to point out again that the corner connection is also evenly sealed to the outside by the insulating layer.

For the connection of the intermediate wall panels connected at right angles to the wall panels, which can also be referred to as inner wall panels, it should be noted that crosswise connections can be formed in the case of intermediate wall panel combinations of several, rectified units oriented at right angles to one another. Here, a uniform free space is created in the joint area of the same pairs of plates from two mirror-inverted recesses, which is open once starting from the upper horizontal and once starting from the lower horizontal, usually after joining together already by connecting the intermediate wall plates to the outer wall panels their sufficient fixation is given.

For the formation of the different butt joints, it should be noted
that a cantilever beam is arranged in each of the wall plates leading to the joint, and each of these beams is connected to a mandrel guide sleeve half protruding into the free space formed by the recess,
that a conical mandrel corresponding to the position of the mandrel guide sleeve halves is provided in the recess of the intermediate wall plate, and that the conical mandrel and the mandrel guide sleeve halves can be non-positively fixed to one another by means of clamping wedges.

The connecting mandrel is introduced into the intermediate wall plate and is arranged with its center approximately in the center of its recess.

In view of the two-part design of the mandrel guide sleeves, the halves of which are U-shaped, and in connection with the fact that two not completely avoidable gaps in the intermediate wall plate to the two rectified wall plates arise, the mandrel preferably has a rectangular shape which deviates from the square basic shape Cross-section.

The two mandrel guide sleeve halves, each of which is fixed in the opposing wall plates by means of a support and anchor loops or the like, engage in the space formed by these recesses in the intermediate wall plate and in this case encompass the mandrel.

The two plates are non-positively fixed as already indicated above.

The second butt joint, which provides for the right-angled, butt connection of an intermediate wall plate to the joint of two rectified wall plates, is characterized by
that in the intermediate wall plate, in the direction of its longitudinal extension to the butt joint, a cantilever is arranged, which in turn is connected to the mandrel guide sleeve provided in the space provided by the recess, and
that a conical half-mandrel is fastened in the joint-forming boundaries of the wall plates, which together form the half-mandrel pair, and the mandrel guide sleeve can be guided over the conical half-mandrels and can be fixed with this by means of clamping wedges.

The criterion of this training is therefore a mandrel division, the half mandrels in the butt-forming delimitations of the recesses of the two wall plates and are fastened to one another in a fixed manner, and together form a half-mandrel pair, approximately square overall cross-section.

Via this half-mandrel pairing, the mandrel guide sleeve arranged in a cantilever from the intermediate wall can be inserted from above. The connection is thus fixed in position by the wedging.

To establish the corner connection between two wall plates or wall plate combinations aligned in the same way, note that
that a cantilevered carrier is arranged in the wall plate, with which, in turn, an assignable mandrel guide sleeve, in this case forming the corner connection, is connected in the recess of the wall plate via the conical mandrel fastened there, and
that the mandrel guide sleeve and the conical mandrel can be non-positively fixed to one another by wedges.

This corner connection also agrees almost identically with the explanations already described, so that further explanation is unnecessary.

For the formation of balconies directed to one side, it is provided that one of the first wall plate combinations connected at right angles to one another and one intermediate wall plate arranged between the wall plate combination perpendicular to this are each formed with a cantilever arm.

Finally, it should be noted that openings of any size - including yoke-like - can be provided in all wall and partition wall panels, and the wall panels generally have storey height.

Apart from the usual openings for doors, windows or the like, the yoke-like design of wall and partition wall panels is particularly interesting, since they enable the formation of larger, coherent spaces that extend beyond the longitudinal extension of the panel unit.

The invention thus fully meets the requirement of the task.
