Description

The invention relates to a connecting element for connecting prefabricated house elements, for example prefabricated wall elements, prefabricated floor elements or prefabricated roof elements, etc., to each other.

The invention also relates to a connector for connecting such connecting elements.

In addition, the invention relates to a precast element.

Finally, the invention also relates to a prefabricated system for connecting elements of a system that comprises the aforementioned connecting elements and a connector.

In prefabricated houses, walls, roofs and, if necessary, also floors are constructed from prefabricated elements that are connected to each other in a variety of ways, for example, using screws, nails, gluing, etc. and their combinations.

A special composite element, which is particularly suitable as a prefabricated element for prefabricated houses, is known from A1858 / 2009 of the applicant. A corresponding composite element is described in FIG.

Due to the special design of these composite elements, it is difficult to connect them together in an optimal way by traditional known methods.

In particular, these composite elements from A1858 / 2009 due to the fact that there is no need to install insulating materials from the outside, as with traditional prefabricated elements, are also suitable so that it can again be dismantled and built on relatively different difficulties the location of a once built house.

The objective of the invention is to provide the ability to easily connect prefabricated elements for prefabricated houses, in particular for prefabricated elements, which are known from A1858 / 2009.

In addition, the object of the invention is to enable subsequent disassembly of houses from prefabricated structures in a simple manner.

This problem is solved by the aforementioned connecting element due to the fact that in accordance with the invention, the connecting element has at least one side surface, as well as an end surface connected to this at least one side surface, the connecting element being adapted to be mounted on the element prefabricated so that these at least two surfaces encompass the element of the prefabricated at least one outer surface, and connecting the element is configured to fasten the at least one side surface to the prefabricated structure element, and the connecting element on the outer side of the at least one side surface has at least one recess extending in the longitudinal direction from the end surface, as well as in the outer side of the end surface of at least one additional recess, and these recesses are made to accommodate a connector that connects two connecting elements of two elements prefabricated, and these elements of the prefabricated are arranged so that the side surfaces of the connecting elements that have a recess, facing each other with the outer sides.

In this case, the outer side should be understood as the side facing away from the prefabricated structural element, and the mounted inner side is facing the prefabricated structural element and adjacent to the prefabricated structural element.

Thanks to the installation of the connecting elements of the invention according to the prefabricated elements, the prefabricated elements must no longer be directly connected to each other, and the connecting elements are connected to each other by means of corresponding connectors. These connectors, if desired, can again be disconnected without breaking, so that the building can be dismantled again. With traditional methods, disassembly without destruction or at least without damage is not possible.

The connecting element is especially stably held on the prefabricated element if it has two side surfaces that are preferably connected to each other and are located at an angle of preferably 90 ° to each other, and the connecting element can be attached to the prefabricated element by two side surfaces designs.

From the point of view of high stability of the connection, it is also preferable if the connecting element can be attached with an end surface to the element of the prefabricated structure.

In addition, it is envisaged that the first and / or second recess has a cross-section which, in the direction extending from the outer side of the side surface that has this recess, is at least partially expanded.

The connector for connecting the two connecting elements due to this configuration of the cross-section of the recesses is protected against slipping in the direction of the outer side, so that the connecting elements can no longer be disconnected from each other in this direction.

For fastening the connecting element to the prefabricated structure element, it is provided that at least one hole is provided in one or preferably both side surfaces through which the connecting element can be connected to the prefabricated element, preferably by means of dowels.

In principle, it would be possible to glue the connecting elements with the elements of the prefabricated structure. Screwing would also be possible.

Due to the use of dowels and pre-made holes in the surfaces, these holes preferably have locking devices, so that the dowel after insertion, even if it has not yet been fixed, can no longer fall out, however, the better possibility of positioning the connecting element on the prefabricated structure is provided .

In addition, it is envisaged that the openings of the two side surfaces are offset with respect to each other in the longitudinal direction of the connecting element.

In this case, the longitudinal direction is understood to mean the direction along the lateral surface, from the end surface to the free end. Due to the displacement of the holes of one side relative to the holes of the other side, it is ensured that the dowels of one side do not intersect with the dowels of the other side.

To ensure high stability of the connection, it is provided that the holes in the side surface, which has a recess, are located outside this recess.

The foregoing is also preferred for composite elements that are known from A1858 / 2009. Moreover, it is preferable if the element of the prefabricated structure, which on its outer and inner sides consists of wooden structural elements, has openings located in at least one of the side surfaces so that the dowels inserted through these openings enter with engagement only into wooden structural elements .

After the wooden structural elements are thus located outside, it is also preferable if the openings are maximally outside.

In particular, for such an element of a prefabricated structure, which on its outer and inner side consists of wooden structural elements and the wooden structural elements inside have cavities, preferably if the dowels have openings.

Dowels can, after mounting in a tree, be filled with, for example, foam, as described in A1858 / 2009, then this foam also partially fills the cavities in the wooden structural elements, so that a particularly stable connection is formed between the connecting elements and the prefabricated structural element.

In addition, it is also preferable if holes are provided on the end surface through which the connecting element can be connected to the prefabricated element, preferably by means of dowels. The same principles apply here as with holes / dowels in the side surface or, respectively, the side surfaces.

In addition, it may also be provided that at least one threaded hole is provided in said at least one recess in the end surface for screwing a connector inserted into the recess.

In practice, the connector is inserted into both recesses in adjacent connecting elements, another connector is put on this inserted connector (the supporting surface of the connectors is flush), and then screwed through both connectors from above, and both of these connectors are screwed to the lower connecting elements . For example, a side wall can then be mounted on the dome protruding at the top of the upper connector.

Screwing on the connector or connectors to the connectors is not necessary, but increases the stability of the connection.

Preferably, if the recess in the lateral surface on its side facing away from the end surface has an extension into which the latch can be inserted, and this latch has a threaded hole.

By means of this lock, for example, it is possible to adjust the height of the floor formed from the elements of the prefabricated structure, as will be described in detail below.

To connect the two connecting elements, as described above, a connector is provided, while the connecting elements on the outer sides of those side surfaces that have a recess are adjacent to each other, and the connector has a support plate and a dome of the connector protruding from this support plate, and the support plate protrudes on both sides of the dome of the connector with identical symmetrical transverse planes, and the dome of the connector has a cross section that is adapted to the cross section hole formed contiguous recesses or, respectively, corresponds to it.

The connector with its dome of the connector is inserted into the hole formed by the sockets or, respectively, the recesses of both side surfaces of the connecting elements, so that the elements of the prefabricated structure can no longer be parted in the lateral direction. With the support plate, the connector is adjacent to the end surfaces of the connecting elements, namely, the support plate in the recesses is adjacent to the end surfaces, so that the connector dome cannot slip through the hole.

In the base plate, the connector preferably has holes for mounting the connector in threaded holes in the recesses in the end surfaces of the connecting elements. The holes in the connector are usually through holes.

It is particularly preferred if the connector has an opening that penetrates the connector, starting from the base plate, along the entire dome of the connector.

This hole also represents a through hole, which serves for several purposes. For example, through this through hole, you can level the height of the floor from the elements of the prefabricated structure or center the two connectors relative to each other, as will be described in more detail below.

In addition, it is preferable if the connector on the base plate, on the side facing away from the dome of the connector, has a socket for a centering element, while the centering element has a threaded hole, which in the inserted state of the centering element is approximately above the piercing hole of the connector.

With the help of the centering element, it becomes possible to center the connector, additionally worn on the connector, relative to the first connector, i.e. the worn connector after slipping can no longer slip or can only to a small extent.

To enable fixation, it is provided that the diameter of the threaded hole of the centering element is smaller than the diameter of the threaded hole of the retainer. Thus, on one side of the connector, a latch can be inserted into the connecting elements, this latch can then be screwed to the centering element through a screw hole of the corresponding length adapted to the diameter of the thread of the centering element, this screw being inserted through the threaded hole of the latch. Thus, for example, the roof element can be screwed to the side wall beneath it.

In the prefabricated element of the invention, the connecting element is located on the prefabricated element in such a way that at least one side surface and the end surface of the connecting element are flush adjacent to the two outer surfaces of the prefabricated element.

Therefore, the elements of the prefabricated structure must be suitably cut so that the connecting elements can be positioned so that they then end flush with the element of the prefabricated structure. Flush means that the outer sides of the end surface and one or both side surfaces form one common surface with the side surfaces of the precast element, that is, lie in the same common plane.

For optimal, stable fastening of the elements of the prefabricated structure to each other, it is advisable if at least one corner of the element of the prefabricated structure, preferably at each corner, is located at least one connecting element. In the case of a rectangular prefabricated element, for example, a connecting element is provided at each of the four corners. If the corner is connected to another precast element, the connecting element is exactly at that corner. The connecting element then covers the lateral surfaces and the end surface of the three outer surfaces of the precast element. In the case of one free angle in the prefabricated structural element, two connecting elements are located next to each other, with recesses facing each other in the side surfaces, so that another connector can be put on this system (two connecting elements connected by a connector).

So that, in particular, it is possible to stably connect to each other larger elements of the precast, it can also be provided that at least one connecting element is located on at least one side that connects the two corners of the precast. Opposite elements of the prefabricated structure can accordingly also be connected to each other on the sides, and not just at the corners.

The connecting elements are arranged on the prefabricated structure element in such a way that in the mounted state of the prefabricated elements, the connecting elements are arranged vertically.

In this case, “vertically” means that the end surface is at the top and bottom, and the side surfaces respectively pass from top to bottom.

Preferred are prefabricated elements, which consist of two wooden structural elements connected to each other by means of a filler, while preferably wooden structural elements have grooves.

The system of the invention for attaching prefabricated elements to each other includes connecting elements, as well as connectors, as described above.

For the manufacture of a floor formed from prefabricated structural elements, the system includes several threaded rods fixed for rotation on floor plates, a latch screwed to these threaded rods, and two lugs connected to each other by two connecting elements and one element connector are mounted on this latch prefabricated structure.

The threaded rods are installed according to a predetermined raster on a plane, for example, on a concrete slab, etc., and then the elements of the prefabricated structure are put on these threaded rods on which the clamps are mounted.

The latches after donning the elements of the prefabricated structure are installed in the connecting elements without the possibility of rotation in the respective sockets of the connecting elements. A threaded rod can rotate through the through holes of the connectors (in the dome of the connector) using a suitable tool, for example, a 6-sided socket wrench, so that the latch moves up or down, and so the floor moves up or down. Thus, it is possible to level the floor of the building.

Optimally, it can be carried out if the threaded rods are mounted on the floor plates by means of hinges.

After the floor is completely leveled, the area under the floor, including the threaded rods, is concreted, so that the weight load no longer lies on the locks. Threaded rods are the only components of the system that cannot be reused when disassembling a house.

The connector can also be designed so that the dome of the connector protrudes from both sides of the support surface; fastening one connector to another (screwing in the connecting elements) is then not necessary, but the possibility of centering is also absent.

Figures 1 and 2 show the components of the system of the invention for attaching prefabricated elements 100 to each other. The system primarily includes connecting elements 1, which are connected to the elements of the prefabricated structure, as well as connectors 200, through which the connecting elements 1 can be connected to each other.

Figure 1 shows a separate system in the area of the floor formed from the elements of the prefabricated structure, with the floor plate 31, on which the threaded rod 30 is mounted rotatably. The latch 15 is screwed onto the threaded rod 30. Preferably, the threaded rods 30 are mounted on the floor plates 31 by hinges.

In addition, centering elements 213 are also shown, the function of which will be described in further detail below.

The threaded rods are installed according to a predefined raster on a plane, for example, on a concrete slab, etc., and these threaded rods, on which the clamps are mounted, are then put on the elements of the prefabricated structure.

The latches after donning the elements of the prefabricated structure are installed in the connecting elements without the possibility of rotation in the respective sockets of the connecting elements. A threaded rod can rotate through the through holes of the connectors (in the dome of the connector) using a suitable tool, for example a 6-sided socket wrench, so that the latch moves up or down, and so the floor moves up or down. Thus, it is possible to level the floor of the building.

After the floor is completely leveled, the area under the floor, including the threaded rods, is concreted, so that the weight load no longer lies on the locks. Threaded rods are the only components of the system that cannot be reused when disassembling a house.

Figures 3 and 4 now show a connecting element 1 from various perspectives in detail. The connecting element 1 has two side surfaces 2, 3, as well as an end surface 4 connected to the side surfaces 2, 3.

The connecting element 1 on the outer side 2a of said one side surface 2 has at least one recess 5 extending longitudinally from the end surface 4, and at least one other recess 7 in the outer side 4a of the end surface 4.

The recesses 5, 7 are made to accommodate a connector 200, which connects to each other two connecting elements 1 of two elements 100 of the prefabricated structure. In this case, the recesses 5, 7 have a cross section, which in the direction from the outer side 2a of the side surface 2 is at least partially expanded.

The connector 200 is also shown in FIGS. 3 and 4. The connector 200 has a support plate 201 and a connector dome 202 protruding from this support plate 201, with the support plate 201 extending on both sides of the connector dome 202 with identical symmetrical transverse planes 201 ′, 201 ″ . The dome 202 of the connector has a cross section that is adapted to the cross section of the hole formed by adjacent recesses 5, 7, or, respectively, corresponds to it.

As soon as the two connecting elements 1 with the outer sides 2a of those side surfaces 2 that have a recess 5 are adjacent to each other, the connector 200 is inserted into the hole formed by the sockets or, respectively, the recesses 5 of both side surfaces 2a of the connecting elements with its dome 202, so that the connectors or, accordingly, the elements of the prefabricated structure can no longer be parted in the lateral direction. With the support plate 201, the connector 202 is adjacent to the end surfaces 4 of the connecting elements 1, namely, the support plate 201 in the recesses 7 is adjacent to the end surfaces 4, so that the connector dome 202 cannot slip through the hole.

The connecting member 1 can be attached to the prefabricated member 100 in the corner region of the prefabricated member 100, as shown in FIG. 6, by means of two side surfaces 2, 3 and an end surface 4.

For this, both side surfaces 2, 3 have openings 10, 11, in a specific example, 4 openings on each side, through which the connecting element 1 can be connected to the element 100 of the prefabricated structure by means of dowels 20 (see FIG. 5 and FIG. 6) . The holes 10 in the side surface 2, which has a recess 5, are located outside the recess 5. Also on the end surface 4, there are (two) holes 12, through which the connecting element 1 can be connected to the element 100 of the prefabricated structure using dowels 20.

Due to the use of dowels 20 and pre-made holes 20 'in the surfaces, these holes preferably have locking devices, so that the dowel after insertion, even if it has not yet been fixed completely, can no longer fall out, however, a better possibility of positioning the connecting element on prefabricated element.

As can be clearly seen in FIGS. 5 and 6, the openings 10, 11 of both side surfaces 2, 3 are displaced relative to each other in the longitudinal direction of the connecting element 1, so that the dowels on one side do not intersect with the dowels on the other side.

If a prefabricated structure element is used, as described in FIG. 15, it is preferable if the dowels 20 have holes 21. After fixing, the dowels 20 can be filled, for example, with foam, as described in A1858 / 2009, then this foam partially fills through the holes 21 also cavities in wooden structural elements, so that a particularly stable connection is formed between the connecting elements and the precast element.

The connecting elements 1 are located on the element 100 of the prefabricated structure so that at least one side surface 2 and the end surface 4 of the connecting element 1 are adjacent flush with the two outer surfaces of the element of the prefabricated structure.

Therefore, the elements of the prefabricated structure must be suitably cut so that the connecting elements can be positioned so that they then end flush with the element of the prefabricated structure. Flush means that the outer sides of the end surface and one or both side surfaces form one common surface with the side surfaces of the precast element, that is, lie in the same common plane.

Under the outer surfaces of an element of a prefabricated structure should be understood surfaces that limit this element, for example 6 outer surfaces in the case of the element, which is shown, for example, in Fig.15.

Figures 7 and 8 now show the fastenings of two prefabricated elements 100 to each other, while the prefabricated elements shown are provided for manufacturing a floor for a building. The image is not fully consistent with reality, but serves to better understand. Both connecting elements 1, which are shown here removed, are mounted on the elements 100 of the prefabricated structure, as described.

Now, the elements 100 of the prefabricated structure are arranged so that the side surfaces 2 of the connecting elements 1, which have recesses 5, face the outer sides 2a to each other, as this can be seen in Figs. 7 and 8.

The connector 200 can now be inserted from above into the hole, which is formed by two recesses 5, and the support plate 201 is laid in the recesses 7. The assembled structural elements 100 thus connected can no longer be extended laterally.

In the example shown, in the recess 7 in the end surface 4 of the connecting element 1, threaded holes 8 are provided for screwing the connector 200 inserted into the recess 7. The connector 200 has holes 210 in the support plate 201, by means of which it can be mounted in the threaded holes 8 in the recesses 7 in end surfaces 4 of the connecting elements 1.

But it is not specifically the connector 200, as shown in Fig. 8, that is directly screwed to the connecting elements 1, but after the insertion of the connector 200, as indicated in Fig. 8, another connector 200, as shown in Fig. 9, is put on the inserted connector shown in Fig. 8, and this connector through the holes 8 through the first connector is screwed to the connecting elements.

A side wall may then be mounted to the connector 200 in FIG. 9 with the upward projecting dome 202 of the connector.

The recess 5 in the side surface 2 on its side facing away from the end surface 4 has an extension 5 '(Figs. 3, 4, 6) into which the latch 15 can be inserted, and this latch 15 has a threaded hole 15' (Fig. 12).

The connector 200 has an opening 211 that permeates the connector 200, starting from the base plate 201, along the entire dome 202 of the connector. This hole 211 is a through hole.

Now, figure 10 shows the system, as in figure 9, again with the "removed" the second element of the prefabricated structure. Here we can clearly distinguish once again the threaded rod 30 on the plate 31. The latch 15 is mounted in the connecting elements 1 (only one is shown) in the corresponding socket 5 'without rotation. Through the through hole 211 of the connector, a threaded rod 30 can be rotated using a suitable tool, for example a 6-sided socket wrench, so that the latch 15 moves up or down, and thus the floor moves up or down. Thus, it is possible to level the floor of the building.

After the floor is completely leveled, the area under the floor, including the threaded rods, is concreted, so that the weight load no longer lies on the locks. Threaded rods are the only components of the system that cannot be reused when disassembling a house.

The connector 200 on the base plate 201, on the side facing away from the connector dome 202, has a socket 212 (FIG. 3, FIG. 7) for the centering element 213 (FIG. 1, FIG. 2). The centering element 213 has a threaded hole (not shown), which in the inserted into the socket 212 state of the centering element 213 is located approximately above the hole 211 penetrating the connector 200.

The centering element 213 embedded in the socket 212 protrudes beyond the support plate 201 of the connector 200, so that another connector 200 can be put on this centering element 213 and, thus, already pre-positioned (Figs. 1, 2).

In order to enable the centering and fixing of the connector, it is provided that the diameter of the threaded hole of the centering element 213 is smaller than the diameter of the threaded hole 15 'of the latch 15. Thus, on one side of the connector, a latch can be inserted into the connecting elements, for example from above, as shown in FIG. .2, this latch 15 may, by means of a screw 40 of an appropriate length adapted to the diameter of the thread to the diameter of the thread of the centering element 213, this screw 40 being inserted through the threaded hole 1 5 'of the latch 15, screwed to the centering element 213.

The corresponding situation, shown in Fig. 2 in an exploded view in the area of the roof-side connection, is shown again in Fig. 12, here already in the assembled and, if necessary, screwed condition.

Figure 11 once again shows the situation in the free angle of the precast element in the floor area. As can be distinguished here, two connecting elements are introduced into the element of the prefabricated structure, which face each other with their recesses 5. The installation of the connecting elements on the free corner makes the sense that a protruding upward connector 200 can be installed on which the side walls 400 can be respectively mounted. The prefabricated structures 100, which are provided for forming the side walls 400, are specially cut to overlap the floor on the side, so that the use of elements 100, as shown in FIG. 15, foam insulation may form around the entire perimeter between the wooden structural elements.

On Fig schematically shows the floor for the building, consisting of individual elements 100 of the prefabricated structure. For optimal stable fastening of the elements of the prefabricated structure to each other, it is advisable if at least at the corners of the element of the prefabricated structure there is a connecting element. In the case of a rectangular prefabricated element, for example, a connecting element is provided at each of the four corners. If the corner is connected to another precast element, the connecting element is exactly at that corner. The connecting element then covers the lateral surfaces and the end surface of the three outer surfaces of the precast element. In the case of one free angle in the prefabricated structural element, two connecting elements are located next to each other, with recesses 5 facing each other in the side surfaces 2a, so that another connector can be put on this system (2 connecting elements connected by a connector).

So that, in particular, it is possible to stably connect to each other larger elements of the prefabricated structure, it may also be provided that at least one connecting element 1 is located on at least one side that connects the two corners of the element 100 of the prefabricated structure, as also shown in FIG. 13. Opposite elements of the prefabricated structure can accordingly also be connected to each other on the sides, and not just at the corners.

Then here the end surface and the side surface cover the outer wall / surface of the precast element, the second end surface extends into the precast element, for which this element must be appropriately cut.

The connecting elements 1 are located on the elements 100 of the prefabricated structure in such a way that they are in a mounted state of the elements 100 of the prefabricated structure are standing, as can be seen in the already described figures, as well as in Fig. 14, which shows a house with a floor, side wall, roof and pediment.

Preferred are prefabricated elements, which consist of two wooden structural elements connected to each other by means of a filler, while preferably wooden structural elements have grooves. Such a prefabricated structural member is described in FIG.

On Fig shows a composite element / element 100 of the prefabricated structure, which consists of an external wooden structural element 1001, as well as at a distance from it from the internal wooden structural element 1002, while between the two wooden structural elements 1001, 1002 is a filler 1003.

Preferably, the filler 1003 is an insulating material, for example, polyurethane foam (PUF) is used, due to which the composite element has very good heat-insulating properties and there is no need to install additional insulation on the outside of the composite element.

For the composite element 100, each of the two wooden structural elements 1001, 1002 has recesses 1005 on its side adjacent to the filler 1003, these recesses being made in the form of grooves.

In the manufacture of the element according to the invention, the intermediate space between the wooden structural elements 1001, 1002 is filled with filler 1003, for example, foamed. Thanks to this, the filler also falls into the recesses of the wooden structural elements that face the (space filled with filler) intermediate space. Then, when the filler hardens, an extremely stable connection is obtained between the wooden structural elements and the filler. In this case, a self-supporting composite element is formed, which is simple to manufacture and in which the occurrence of heat / cold bridges can be prevented, since nails, screws, etc. are not needed to connect two wooden structural elements. More details are contained in the applicant application A1858 / 2009.
