Building block

The invention relates to a building block according to the preamble of claim 1 *

In a known module of this type (DE-OS 2o 05 642) the connector is I-shaped and protrudes with a of the two angled end sections from above into an associated one , vertically running opening, while the web with its ends on the associated longitudinal edges of the inner and outer part rests. The other end section protrudes vertically upwards and is used to connect the module an overlying building block of a wall. For this purpose is the other end section inserted into an adapted opening on the lower longitudinal edge of the inner and outer part * When filling of this building block, the web lies transversely to the direction of filling of the potting material, so that it has a relatively large contact surface and obstructs the free flow of the filler material. The crossbars are due to the pressure of the filling material

'' exposed to unfavorable force conditions. This can lead to damage to the connector. ,the Connectors are-; particularly stiff and therefore relatively expensive. . Due to the unfavorable force * \ *. ' their end sections can be relatively easily removed from the webs and the fastening of the connector ends in the recesses the associated openings are torn out so that the inner and outer parts are no longer securely connected to one another and the module can be damaged as a result. Since the web rests on the longitudinal edges of the inner and outer part, a horizontal gap remains between building blocks arranged one above the other with a gap corresponding to the thickness of the webs Height. Such a gap can have the insulating effect of such building blocks. ···:. ··,. ··. ·· .:.;

produced masonry or its soundproofing or the like and must be treated separately when plastering. About damage and an injury There is a risk of upward movement through the inside «and Outer part protruding through one end of the Connectors formed to prevent connecting parts during «transport and storage * can Plug connector »only on site at the construction site« into the Inner and outer parts are inserted so that the bearings attitude and the production costs of a masonry formed from such building blocks »made considerably more difficult will. After all, it is also difficult and time-consuming to put the building blocks on top of one another because they must be aligned very precisely against one another in order to insert the connecting parts into the associated openings of the to be able to plug the lower longitudinal edges of the inner and outer part.

The invention is based on the object of a module to train this type so that the connector and i £ re connection with the inner and outer parts have a high resistance against the tensile and bending forces acting on them due to the pressure of the Püllmateriales and that the handling such building blocks on the construction site is facilitated.

In the case of a module with the features of the generic term, this object is achieved according to the invention by the features of the characterizing part of the claim!

Since the connectors both with the ends of the webs as

abg e bo-related
with their end sections lying over their entire height in the associated recesses, they are in the interior and exterior

Outer part anchored very firmly. You can therefore not go out the recesses are torn out and thus the module according to the invention is not damaged. Since the Web of the building blocks are in the direction of filling of the filler material, they have a high resistance to deformation the pressure exerted by the filler material »so that they cannot deform significantly even under unfavorable conditions »The web in the filling direction also hinders the flow of material when filling the hollow space * · IHfB not »so that this is filled out better and more precisely can be. In addition, building blocks according to the invention be placed on top of each other without gaps, so that no horizontal gaps remain that have to be plastered separately and affect the properties of the building blocks, such as sound insulation »sound insulation or the like * The recessed arrangement the web ends and the end sections in the associated openings and the profiled design of the connecting parts also has the advantage that the building block does not have any protruding corners and edges that could cause injuries or damage the component. The block can therefore already be in the Factory assembled. In addition, the building blocks can be quickly and easily assembled on the construction site Move one on top of the other, as they ^ due to the tongue-like groove Simply align the connecting parts to one another and subsequently to adapt to the respective structural conditions Can be shifted against each other without a grid.

Preferred designs and developments as well as further advantages and essential details of the invention are from the features of the subclaims, the following description and the drawings. The drawings show a schematic representation of an example of the building block or shuttering block according to the invention. It shows:

The module 1 shown in FIGS. 1 to 4 consists of an inner part 2 and an outer part 3, which is at a distance from and parallel to this, and which are connected to one another with connectors ^. The inner and outer parts 2, 3 each have an approximately rectangular outline and are made of foamed plastic, in particular of rigid polystyrene foam. To increase the insulating effect of the building block 1, the outer part 3 is preferably greater than the inner part 2. The inner and outer parts 2, 3 each have a circumferential rib 9, on their one end face 5, 6 and one longitudinal edge 7, 8. 10 and on its other end face 11, 12 and its other longitudinal edge 13, I ¹ * each have a circumferential groove 15, 16 each with the same cross section. The webs and grooves form tongue and groove-like connecting parts for connecting the building block 1 with the same or similar building blocks to form masonry, in particular a wall 17 (FIG. Lo). For this purpose, the building blocks 1 are placed in a row next to and on top of each other on a foundation 36, the grooves 15, 16 of the respective subsequent building blocks 1 being inserted into the rib 9, Io of the building blocks 1 that were previously moved. As a result, the building blocks are precisely aligned with one another, so that the cavities 18 present between the inner and outer parts 2, 3 essentially form a common cavity in the masonry 17. This is filled with flowable filling material,

preferably plastic concrete »decays as soon as the masonry or the wall 17 is pulled up to over a storey height. That. Filling material is brewed into the cavity 18 in a known manner with a pump.

Due to the nutfederartxge connection between the mutually associated ribs S, Io and the grooves 15, 16, the building blocks can be aligned with one another easily and very precisely in a short time. The building blocks can be shifted against each other through the uninterrupted grooves 15, 16, whereby a gridless building system is formed, which can be easily adapted to the respective building conditions.

In the case of the module 1, eight identically designed connector prebinders k (FIGS. 7 to 9) are preferably provided, which are each equally spaced from one another. The number and spacing of the connectors Ί depends on the length of the building blocks, so that, for example, in the case of a shorter building block, fewer connectors can be provided at a greater distance from one another. The connectors H are made of fireproof material, such as galvanized sheet metal, so that they ensure fire protection. They preferably have T 'shape with a flat, rectangular land ¹ Ia at both ends in flange-2o and

gtwa__ £ slightly broad opposite directions of angled Enaoscnnitte 19, 28 passes, which together form the ends 27 of the connector 10. The plug connectors k can, however, also be U-shaped or Z-shaped, each with only one end section angled in the same or in opposite directions.

The connector 4 lies with its ends 20 and the end sections 19, 28 in adapted T-shaped, slot-shaped recesses 21 of the inner and outer parts 2, 3. The recesses 21 consist of an opening 21a that is open at the top and in the direction of the cavity 18 for the ends 2o (FIG. 8) of the web 4a and two openings 21b and 21c lying at right angles to this for the end sections 19 and 28. The openings 21b, 21c are located approximately in the outside 31 of the rib 9 x the outer part 3 both of the same size, so that when assembling the connector it is not necessary to pay attention to a specific assignment of the end sections 19, 18 to the opening 21b, 21c. The recesses 21 are preferably undersized in relation to the thickness of the ends 27 of the plug connectors 4 - including beads 26, 30 (FIGS. 6, 7, 9) provided on the plug connectors 4. As a result, the ends 27 of the plug connectors 4 are held in the inner and outer parts 2, 3 with a press fit or press fit, so that they are securely held in the recesses 21 even in the event of greater temperature fluctuations and the effects of forces. These can be formed by appropriately designed approaches, such as noses, projections or the like, with a foaming mold when the Ixinenond outer part 2, 3 is foamed. However, they can also be attached subsequently in the foamed inner and outer parts 2, 3 by milling, punching, slitting or the like .

The openings 21b, 21c each have a predetermined distance a, a ¹ from the outer surfaces 22 of the inner and outer parts 2, 3 (FIG. 2, lo). In the case of building block 1, which has a length of about 1 m, a width of about 0.?. ^ M and a height of about 0.25 m, this distance is at least about 10 mm.

As a result, the ends 27 of the connector 4 are inserted so deeply into the inner and outer parts 2, 3 that the connector ends 27 under tensile force can be avoided. Because of this position of the recesses 21, no cold bridges can form in the area of the connector 4 "if the connector is made of a thermally conductive material such as metal" between the outer surfaces 22, 23 of the inner and outer parts 2, 3 * the relatively high ones Temperature fluctuations can be exposed and the connector end sections 19 »28, namely still remains a relatively wide insulating layer of the thickness a _/ a ^t * In addition, the inner and outer parts 2, 3 have uninterrupted outer surfaces 22, 23 that can be easily processed, e.g. plastered .

The recesses 21 are preferably in the upper and lower edge area R or * R (Pig. lo) of the inner and Outer part 2,3. As a result, the recesses are only provided in a relatively narrow edge area, while the largest Part between the longitudinal edges 7, 13 or 8, 14 of the inner and outer part have no recesses, so that the flexural rigidity of the building block through the recesses is not affected.

On the upper narrow longitudinal edges 7, 8 of the inner and outer Outer part 2, 3 are for receiving the connector ends eight opposite each other. Recesses 21 intended. There is a corresponding number of recesses also present on the lower longitudinal edges 13, 14. So are

in the building block 1 per running meter there are about 16 connectors, whereby the building block has very good strength properties, so that the inner and Outer part 2, 3 ifl the area between the connectors 4 can only bend within permissible limits.

In order to avoid protruding parts and slots that are too deep, the building block 1 is preferably designed so that the outwardly pointing edges 4, 4 "of the connector 4 are approximately flush with the base 24 of the grooves 15, 16 or the feet 25 of the ribs 9, Io of the associated end faces 5, 6 _S 15, 16 or the associated longitudinal edges 7, 13, 8, 14 of the inner and outer parts 2, 3 lie.

The plug connectors 4 of the module 1 are preferably made of flat material, in particular of galvanized sheet steel, so that they can be manufactured easily and at low cost. To increase the strength, each connector 4 preferably has two ^{longitudinal beads 26 running directly adjacent to the edges 4 f} , 4 ″ and transverse beads 3 o located on the end sections 19-28. The longitudinal beads 26 extend over the entire length of the connector and run parallel to its edges 4 ', 4 ". The transverse beads 3o each extend over almost the entire length of the end sections 19, 28. They run between the Longitudinal beads and with a small distance parallel to them. When the connector 4 is manufactured, the stamped part 4b shown in FIG. 6 is first manufactured. It shows at both ends 27 a tab-like, rectangular central part 28b, which extends between the longitudinal ribs 26. This is partially punched out of the punched part 4b, so that it only has a longitudinal edge 29a (Fig. 6) is connected to the punched part 4b.

Then the one end sections 19 are equal by 90 °

The other, partially punched-out end pieces 28b are then also bent outwardly by 90 ° around the bending axis 29 in the opposite direction.

Through the transverse beads 30 and the end sections 19 protruding ends of the longitudinal beads 26 have both end sections 19> 30 high strength *

In the web 4a of the connector 4 (Fig. 6 to 9) are preferably two with approximately the same distance from each other and through openings 32 lying from the end sections 19, 28 for one quick-release screw (not shown) or the like. With these, neighboring building blocks, such as an end block and a subsequent one Winkelstein to be connected to each other. This creates, for example, an end stone on a corner stone of a masonry anchored so that he is when backfilling the cavities can't move away from this.

Due to the one-piece design of the connector 4, it can be manufactured without material waste. His Production from flat material is easy, as only relatively simple operations such as cutting, beading, bending, and notching are required. The length of the connector 4 can be varied in a simple manner by

For example, the end sections 19 are bent more or less wide. It is particularly advantageous that the building blocks according to the invention are due to their web 4a in the filling direction and the hook-like anchoring and recessed position of the connector ends 27 in the associated angled recesses21 of the inner and outer parts 2,3 tensile and bending forces caused by the concrete pressure can take up very cheaply. The connector webs 4a have in

The recessed position of the connector ends 27 (V v / also avoids injuries when moving the modules and • when transporting protruding parts as well as damage to the connector itself the

Building blocks, so that these are very precisely and completely can be filled. Since the connector ends 27 opposite: over the associated groove base 24 and the associated

Rib foot 25 of the connecting parts 9, Io, 15, 16 are set back, the blocks can be moved without gaps. It is also advantageous that the connectors 4 '■ due to their lateral distance from the inner and outer parts 2, 3 are easily adapted to the requirements of the respective static structural strength, the required sound insulation or structural conditions, if necessary, on site can. Overall, this results in a very simple, highly variable and, moreover, extremely inexpensive to manufacture module 1.

Like Pig. 4 shows, the building block can also be designed as an L-shaped corner stone, the long leg 33 of which is, for example, one meter long and the short leg 35 'measured from the outer corner edge of the corner stone to the end face 35 of the short leg _{3 has} a length of 0.5 m, for example. The width of the inner part 36 de3 corner stone kk , like that of the inner part 2 in the case of building block 1 according to Pig.l, is 50 mm and the width of the outer part 37, corresponding to that of the outer part 3 of the building block 1, is preferably 70 mm. As in the case of building block 1, webs 4a that are adjacent to one another now have a spacing of approximately 125. Of course, any other suitable dimensioning is possible.
