Abstract

The device (30) has a laminar base plate (32) that is temporarily connected with one of wooden units (29l, 29r) e.g. wooden beams. Empty conduits (14l, 16l, 18r, 20r) run out from the base plate and exhibit a spatial progression, such that screws (22hl, 22vl, 22hr, 22vr), which enter an empty conduit end facing the base plate, take up a screw path. The screw path penetrates from one of the wooden units to the other wooden unit. The spatial progression in a Cartesian coordinate system corresponds to a progression of space diagonals. Independent claims are also included for the following: (1) an inserting unit for producing a screw channel in a laminar concrete unit (2) a wooden/concrete-connection unit with an inserting part (3) a wooden/concrete-connection structure such as wall-and/or-cover part exhibiting two wooden/concrete-connection units.

Description

The present invention relates to an assembly jig for a connection of two at least partially flat juxtaposed wooden elements and an insert element for generating screw channels in a flat concrete element. Further, the present invention relates to a wood / concrete composite element with at least one such insert element and to a wood / concrete composite structure with at least two wood / concrete composite elements and to the corresponding connection methods.

In the construction of new houses, workshops and in the refurbishment of old buildings, there is a great need for statically perfect connections of wooden beams / frames with concrete elements and simple wood / wood connections. Such concrete elements are combined with the wooden beams / wooden frames to form so-called wood / concrete composite structures and are used as walls or coverings. These wood / concrete composite structures have the advantage over pure wood construction that they are still comparatively light despite the proportion of concrete and despite the wood content still have a sufficiently high heat storage mass. Furthermore, such structures significantly improve the acoustic properties of a building and also have a good fire resistance. With the improved soundproofing, they also reduce noticeable vibrations of floors and therefore stiffen the building statically outstanding. Apart from these technical advantages, the visible wooden beams also satisfy the aesthetic wishes of the client.

For connecting individual wood / concrete composite elements to these wood / concrete composite structures, there are many more or less expensive solutions known. One solution, for example, provides for the formation of in-situ concrete bags, which, however, have to be concreted out in situ on a dry construction site, which is otherwise rather free of concrete in timber construction. However, the use of concrete is usually undesirable on such a dry construction site and always associated with a comparatively high outlay. In addition, crossed double-threaded screws are used here. However, these bottom-mounted screws are visible, which may detract from the aesthetic appeal of these composite structures. In principle, it is also possible to insert steel parts in the concrete slabs, which must be welded after assembly of the composite elements. However, in wood construction, the risk of fire during welding is relatively high.

All currently known solutions, therefore, the flaw depends on the fact that they provide statically perfect composite structures, but the material and labor required to create these composite structures but high and thus the entire composite structure is relatively expensive.

Based on this prior art, the present invention therefore has the object to solve the problem of connecting wood / wood composite elements, wood / concrete composite elements for the creation of wood / concrete composite structures with simpler means and more cost-effective.

1. a) eine flächige Grundplatte, die geeignet ist mit einem in xy-Richtung verlaufenden Randbereich des Betonelements bündig abzuschliessen;
2. b) mindestens ein von der Grundplatte ausgehendes Leerrohr, dessen Hohlraum den Schraubenkanal darstellt, wobei das Leerrohr so einen räumlichen Verlauf aufweist, dass eine an dem der Grundplatte gegenüberliegenden Ende des Leerrohrs eintretende Schraube einen Schraubweg nimmt, der über die seitlichen Randbereiche des Betonelements hinausgeht.

This object is achieved with respect to the insert element according to the invention by an insert element for the production of screw channels in a flat concrete element whose expansion in the x and y direction is large against the expansion in the z direction. This insert element comprises:

1. a) a flat base plate, which is suitable to be flush with a running in the xy direction edge region of the concrete element;
2. b) at least one emanating from the base plate empty tube, the cavity of which represents the screw channel, wherein the empty tube has a spatial course, that at the base plate opposite the end of the empty tube entering screw takes a screw that goes beyond the lateral edge regions of the concrete element.

In this way, it is possible to keep clear with the insert element in the concrete element a screw channel, whereby the screws, which are provided for connecting the wooden beams adjacent arranged wood / concrete composite elements, on the one hand when screwing are guided and on the other hand a later Schraubweg is marked in the wooden beams , This Schraubweg is essentially given by the required static properties of this connection and can be adjusted individually for each type of composite structures by a corresponding arrangement of the conduits (previously). With the beyond the lateral edge regions of the concrete element extending screw so that the safe and proper connection of the wooden beams can be achieved. In addition, this configuration of the insert element allows the screws to be screwed into the empty tubes from above, which simplifies the assembly of the screws through the empty tubes considerably compared to the overhead work known in the prior art.

The static properties of a connection of the wooden beams, which can be achieved by screwing the screws through the conduits, can be achieved particularly well if the spatial course of the conduits in a Cartesian coordination system with the directions x, y and z a course of a spatial diagonal ( or with several conduits also several spatial diagonals) corresponds. This is basically to be understood that in a compound with, for example, four screws, the four screw tips and the four screw heads an octagonal, essentially represent cuboid composite. Accordingly, it is also expedient with regard to the computability of the connection and the uniform distribution of tensile and compressive moments on the screws, if the spatial course through an angle of 30 to 60 °, preferably in the range of 45 °, to each of the three directions x, y and z is coined.

For the connection of the wooden beams, it is particularly important that the screws can be screwed with a manageable amount of force and have an X-shaped arrangement to each other. For this purpose, it is advantageous to provide two conduits, which are aligned substantially orthogonal to each other, wherein the predetermined by their screw channels screw paths are crossing free. By this consciously a little asymmetrical arrangement of the conduits is just reliably avoided that meet the screws on their Schraubweg in the wooden beam. For the connection of two wooden beams this means in an expedient development of this idea that an asymmetrical orientation of the conduits is provided in such a way that the prescribed by two abutting with their base plates insertion elements screw essentially the four space diagonals of a cuboid, preferably a cube, describe , where the screw paths are crossing-free. As already explained above, in this connection with four screws, an octagonal, essentially parallelepipedic compound formed by the four screw tips and the four screw heads is formed (note: crystallographically, one would speak here for a cubic lattice of the <111> directions).

Thus, the one or more conduits of the insert elements during the concreting concrete element can not be closed (unintentionally), the base plate opposite the end of the empty tube with a removable lid can be designed lockable.

In order to make it universally applicable to the insert element for a variety of different thicknesses of the concrete element (expansion in the z direction), can be provided in an advantageous development of the invention to make the empty tube telescopically adjustable in its length.

Screwing the screws through the conduits into the wooden beams requires a comparatively high pressure of the screwing tool on the screw head, which may not protrude significantly beyond the thread cross section of the screw. In order to facilitate this pressure and the orientation of the screwing tool, it is provided in a further embodiment of the present invention to provide the base plate opposite end of the empty tube with a flange to which a required for driving screws through the screw channels tool can be coupled.

Figure 1 shows a perspective view of two wood / concrete composite elements 2, 4, which must be connected to form a wood / concrete composite structure. Each wood / concrete composite element 2, 4, has a concrete slab 6, which runs in the diagram in the xy plane and is significantly longer in the x-direction as well as in the y-direction than they strong in the z-direction. The concrete slab 6 is in the drawing on wooden beams 8, wherein the adjacently arranged wooden beams 8l and 8r are to be connected to create a wood / concrete composite.

FIG. 2 now shows, in an enlarged detail view, the two wood / concrete composite elements 2, 4. On each of the wooden beams 8l and 8r there is an insert element 10l and 10r. The insert elements 10l, 10r have a flat base plate 12l, 12r which in each case terminate flush with the lateral edge region of the concrete elements 6 extending in the xy direction. The insert elements 10l, 10r have been fastened here with screws not shown here on the wooden beams 8l and 8r before the concrete slab 6 were concreted. Furthermore, they each have two empty tubes 14l, 16l or, 18r, 20r which emanate from the base plates 12l, 12r and whose cavities represent a screw channel for a screw 22. This screw 22 is shown in Figure 2 in an enlarged view (relative to the remaining contents of Figure 2) on the left edge of the picture. The empty tubes 14l, 16l and 18r, 20r have a spatial course in such a way that the at the base plates 12l, 12r opposite ends 24 of the conduits 14l, 16l and 18r, 20r entering screws 22 takes a Schraubweg over the lateral edge regions of the concrete elements 6 goes out, which is shown in Figure 3 and will be explained in more detail below. The spatial course of these conduits 14l, 16l and 18r, 20r has in the registered in Figure 1 Cartesian coordination system with the directions x, y and z the course of a room diagonal, if one imagines a substantially cuboid (cubic in the embodiments) composite whose eight vertices is formed by the four screw ends and the four screw heads.

Basically, the spatial course depending on the selected cuboid composite can be characterized by angles of 30 to 60 °. Especially for static reasons and because of the better predictability of the load moments in the three directions of the Cartesian coordinate system, an angle of about 45 ° is selected for the spatial course, as is the case here in the exemplary embodiments.

In order that the screws 22 can each be freely screwed by the screws along the other screw paths, the two empty tubes 14l, 16l and 18r, 20r are provided, which are aligned substantially orthogonal to each other, but have a certain asymmetrical arrangement, so that their through the screw channels pre-drawn screw paths are crossing free. For example, the distance of the empty tube 18r from the lower edge of the base plate 12r is substantially smaller than the distance of the empty tube 20r from the upper edge of the base plate 12r. This can also be clearly seen on the insert element 101 positioned on the other side, the position of which results from the rotation of the insert element 10r by 180 ° in the xy plane.

FIG. 3 shows the cutout according to FIG. 2 after a connection of the two wood / concrete composite elements 2, 4 to a wood / concrete composite structure 26. The asymmetrical alignment of the empty tubes 14l, 16l or 18r, 20r is clearly recognizable two with their base plates 12r, 12l abutting insert elements 2, 4 predetermined screw paths essentially the four space diagonals of a cuboid, preferably a cube, describe, the screw paths are crossing free. The screw 22vl is here passed through the empty tube 14l when screwing. Accordingly, the screws 22hl, 22vr and 22hr have been screwed through the empty tubes 16l and 18r and 20r, respectively. Although the heads of the four screws 22vl, 22hl, 22vr and 22hr are not discernible in FIG. 3, it is easily conceivable that the four visible screw ends and the four screw heads represent the vertices of a substantially cubic body and the four screws 22vl, 22hl , 22vr and 22hr follow the four space diagonals of this essentially cubic body.

Figure 4 shows a sketch of Schraubwegen T1 to T4 for a cubic Elemementarzelle with an edge length of 10 cm. The screw T1 to T4 each extend at an angle of 45 ° to all three directions x, y, z. The positions of the initial locations S1 to S4 of the screw paths T1 to T4 and the end locations S1 'to S4' when the screw paths T1 to T4 strike a plane parallel to the xy direction for z = 10 cm are shown in FIG. As a result of the asymmetrical arrangement of the initial locations S1 to S4, the screw paths T1 to T4 run through the unit cell without crossing (unlike the four space diagonals of the unit cell meeting in the center Z). Although the graphic representation according to FIG. 4 could have a slightly distorting effect, it is still understandable that the four initial locations S1 to S4 and the four end locations S1 'to S4' represent the vertices of a substantially cubic composite, as described above has already been addressed. Of course, it is clear that this cubic composite due to the internal arrangement of the four starting points S1 to S4 expands outwardly in the z-direction with progressive extension of the screw T1 to T4. For the end points S1 'to S4' therefore a screw length 1 was assumed, which corresponds to the length of the spatial diagonal of the unit cell.

So that the four conduits 14l, 16l, 18r, 20r of the insert elements 101, 10r during concrete concreting the concrete slabs 6 can not be (inadvertently) closed, the ends 24 of the conduits 14l, 16l, 18r, 20r can be closed with a removable, but not shown here lid. In order to use the insert elements 10l, 10r universally for a variety of different thicknesses of the concrete slab 6 (expansion in the z direction), the conduits 14l, 16l, 18r, 20r are telescopically adjustable in length in not shown here.

Since screwing the screws through the conduits into the wooden beams a comparatively high pressure of a screwing not shown here on the screw head 28, which does not protrude significantly beyond the thread cross-section of the screw 22 in the illustration shown in Figure 2, it may be to facilitate This Andrucks this orientation of the screwing be provided to equip the ends 24 of the conduits 14l, 16l, 18r, 20r with a flange not shown here, to which for driving the screws 22 through the screw channels (cavities of the conduits 14l, 16l, Depending on the dimensions of the wood / concrete composite elements 2, 4 and / or the required static properties of the connection of adjacent wood / concrete composite elements 2, 4, a suitable number of such integrated insert elements 10l, 10r is provided, which in Figure 1 by in the concrete slabs 6 sym bolisch drawn holes is represented.

FIG. 5 shows, in strong analogy to FIG. 3, a connection of two wooden beams 291, 29r with the aid of an assembly jig 30. The assembly jig 30, unlike in the exemplary embodiment according to FIG. 3, is now configured in one piece and therefore has a substantially square base plate 32, from the (analogous to the embodiment of Figure 3) now more the four conduits 14l, 16l, 18r and 20r protrude. The empty tubes 14l, 16l, 18r and 20r give Here, due to their spatial orientation, the screw paths for the four screws 22vl, 22hl, 22vr and 22hr, wherein the letters attached to the reference numeral 22 represent, through which the conduits 14l, 16l, 18r and 20r, the respective screw was screwed. Also in this embodiment, the diameter of the head 28 of the screw 22 is only about as large as the diameter of the screw 22 itself.

In a manner not shown here, openings may also be present in the base plate 32, in which other screws for temporary fixing of the assembly jig 30 on the two wooden beams 291, 29r can be arranged. An alternative or additional fastening method can also be achieved by means of screw clamps. After screwing the four screws 22vl, 22hl, 22vr and 22hr through the four empty tubes 14l, 16l, 18r and 20r, these temporary fixing means can be released again and the assembly jig 30 can be inserted elsewhere.

Like the insert elements 12l, 12r, the assembly jig 30 can also be made entirely of metal or a correspondingly stable plastic. In the case of the assembly jig, the conduits 14l, 16l, 18r and 20r may each be supported in their own position by additional means, for example by supporting webs. However, other means may also be provided which also support the empty tubes 14l, 16l, 18r and 20r with one another and thus contribute to the stability of the assembly jig 30.
