Description

The invention relates to a wood-concrete connection kit with the features of the preamble of claim 1.

For example, in a renovation of old buildings is occasionally poured to a sound insulation and / or static reinforcement of an existing wooden ceiling, which also forms a floor of an upper floor, concrete on the wooden ceiling. However, a static reinforcement is only achieved or at least substantially improved if the concrete rests not only on the wooden ceiling but shear-resistant connected with it.

For such a shear-resistant connection proposes the European patent application EP 0 432 484 A2 a special screw having a wood screw thread extending over a part of a length of a screw shaft and having a non-threaded screw shaft between a screw head and the wood screw thread. The unthreaded screw shank has a radial flange at a distance from the screw head. The special screw is screwed through boards of a wooden ceiling into a wooden beam of the wooden ceiling until the radial flange rests on the boards. Subsequent to the boards of the wooden ceiling poured concrete surrounds a protruding from the boards part of the screw shaft and the screw head, so that a shear-resistant bond between the concrete and the wooden ceiling is achieved.

To produce a shear-resistant connection between a wooden ceiling and a poured onto the wooden ceiling layer of concrete proposes the international patent application WO 2015/097 663 A1 Angles made of metal strips whose legs are arranged at right angles to each other and stiffened by a metal strip, which connects the two legs at an angle of 45 °. The angle is placed on a wooden ceiling so that one leg rests on the wooden ceiling and the other leg is perpendicular to the wooden ceiling upwards. To a mounting on the wooden ceiling is a screw perpendicular to the two legs connecting metal strips and thus at an angle of 45 ° to the two legs of the angle by a Hole in a center of the metal strip connecting the two legs and a hole at a corner of the angle, where the two legs meet, screwed into the wooden ceiling. Concrete poured onto the wooden ceiling encloses the angle, creating a shear-resistant bond between the concrete and the wooden ceiling.

The object of the invention is to propose a wood-concrete connection kit for producing a shear-resistant composite between a wooden ceiling and poured concrete on the wooden ceiling.

This object is achieved by the features of claim 1. The wood-concrete connection kit according to the invention has anchors, each with one or more screw holes for passing a screw to a setting of the anchor on a wooden ceiling. The through hole has an abutment for a screw head. The abutment for the screw head may be, for example, an annular stepped or frusto-conical diameter reduction of the through-hole. However, the abutment does not necessarily have to be arranged in the through hole, but can also connect to it. The anchors can be cast around with concrete. By "anchor" is meant a component castable with concrete, which due to its shape and possibly its surface finish has hold in the concrete. If the anchor is arranged as intended on a wooden ceiling, it holds concrete, which is or is poured onto the wooden ceiling and enclosing the anchor, parallel to an upper side of the wooden ceiling, on which the anchor is arranged, so that a shear-resistant connection between the concrete and the wooden ceiling, when the anchor is fixed to the wooden ceiling. In addition, the anchor can give the concrete hold against lifting off the timber ceiling and / or in another direction. The wooden ceiling can generally also be understood as a substrate on which the anchor is arranged, is arranged or is to be arranged.

A base made of wood, associated concrete and the wood-concrete connection kit together form a wood-concrete composite according to the invention.

Furthermore, the wood-concrete connection kit according to the invention has an anchor connector for connecting a plurality of anchors. The armature connector and the armatures have cooperating attachment means by which the armatures are connectable to the armature connector. Preferably, the anchor by means of fastening devices without tools, for example by plugging, connectable to the anchor connector. By means of the anchor connector can be several anchors, the are connected by means of fastening means with the anchor connector or to arrange together on the wooden ceiling. The anchors can be attached to the wooden ceiling via the anchor connector. Preferably, however, the anchors are themselves mounted on the wooden ceiling, regardless of a possible attachment of the anchor connector on the wooden ceiling. The anchor connector is used in particular for a simple arrangement of the anchor at designated locations on the wooden ceiling.

Preferably, the anchor connector of the wood-concrete connection kit according to the invention anchors, which are fastened with the fastening means on the anchor connector, in a straight line and / or at regular intervals or a regular surface arrangement, for example, at regular longitudinal and transverse distances. "Regular" means equal or unequal distances, but repeating in regular patterns. As a result, joints are set at which the wooden ceiling shear-resistant connected to the concrete.

A likewise preferred embodiment of the invention provides that the anchor connector holds at least two anchors, which are fastened to the anchor connector with the fastening devices, aligned identically. For example, the anchor connector holds anchors secured thereto with fasteners longitudinally or transversely of the anchor connector. It is also possible that anchor can be fastened with the fastening devices oriented opposite to the anchor connector. If the anchor connectors have slanted screw holes, screws can be screwed against one another diagonally through the screw holes of the anchors into the wooden ceiling.

For example, the anchor connector is in the form of a straight strip to which the anchors can be fastened with the fasteners in a straight line and at equal distances and / or the same or opposite orientation. The strip can be rolled up for storage and delivery and rolled out when laying on the wooden ceiling.

An embodiment of the invention provides connectors as fastening means for the anchor on the anchor connector. The connectors can be performed, for example, on the type of plug and coupling, as dovetail connections or as T-slots and T-bars. A connecting or plugging direction can be vertical, oblique, longitudinal or transverse to the anchor connector. The examples serve to illustrate possible attachment means without limiting the invention to the examples.

An alternative embodiment of the invention provides snap connector as a fastening device for the anchor on the anchor connector. Snap connectors function similarly to snaps, although they are rather deviantly designed or shaped. Snap connectors allow the anchors to be connected to the anchor connector by compression, with the anchors snapping into place on the anchor connector. By pulling apart, the anchors can be released again from the anchor connector. Instead of snap connectors, the armature and armature connector may also include detent connectors which snap-lock, rather than snap, and snap the anchors to the armature connector, but which are no longer releasable by being pulled in the opposite direction to snap. A solubility by a relative movement of the armature to the anchor connector in a direction other than opposite to the direction of engagement can be given. The snap connectors and / or snap connectors may be present instead of the connectors or in addition to the connectors.

An embodiment of the invention provides predetermined separation points of the anchor connector between the fastening devices. These are, for example, thin, narrow and / or notched points of the anchor connector, at which the anchor connector can be separated by hand without tools. This allows in a simple manner a separation of an anchor connector in a desired length of an arbitrarily long anchor connector. The anchor connector may, but need not, have a desired break point between all fasteners. The predetermined separation points can also be provided after a plurality of fastening devices.

An embodiment of the invention provides that the anchor connector fastening holes for fixing with, for example, nails or screws on the wooden ceiling, so that the anchor connector does not slip after its arrangement on the wooden ceiling until or during casting of the concrete.

An embodiment of the invention provides an adhesive on the anchor connector for fixing on the wooden ceiling. For example, one side of the anchor connector is provided with a self-adhesive layer of adhesive, which is covered for example with a protective film. In addition to the adhesive, the anchor connector may have mounting holes.

A development of the invention provides that the anchor connector has an elastic base, for example an elastic foam layer or an elastomer layer, which is provided with the adhesive to compensate for unevenness of the wood ceiling and / or produce a seal, for example, if to protect against moisture Foil is laid on the wood before attaching the wood-concrete connection kit. In this case, a leak could occur in the region of the screw, which can be prevented by an elastic pad on the anchor connector.

In a preferred embodiment of the invention, the anchor connector apertures such as holes covering the mouths of the screw holes of anchors, which are connected to the fastening means with the anchor connector. Screws for securing the anchor can be screwed in this embodiment of the invention through the screw holes of the anchor and the openings of the anchor connector in the wooden ceiling, on which the anchor connector is arranged with the anchors.

A development of the invention provides that the wood-concrete connection kit has sheaths, which are aligned with the screw holes on the armature connector facing away from the anchor attachable. The cladding passes through the concrete, so that the screw holes of the anchors are still accessible even after concreting. This is an advantage, for example, if the anchors are embedded in a prefabricated concrete part, which is later laid on the wooden ceiling or other substrate. Through the cladding tubes and the screw holes of the anchors, the precast concrete part can be screwed to the wooden ceiling or the other subsoil.

In a preferred embodiment of the invention, the screw holes of the anchor extend obliquely to the anchor connector when the anchors are secured in the intended manner by means of the fastening means to the anchor connector. This screws through the screw holes obliquely screwed into the wooden ceiling, which allows a transfer of greater thrust in one direction between the timber ceiling and the concrete.

A refinement of the above embodiment of the invention provides that armatures oriented opposite one another can be fastened to the anchor connector with the fastening devices. "Opposite oriented" means that the screw holes of different anchors are oppositely oriented obliquely. This allows anchors to be slanted in one direction and other anchors slanted in one direction Fasten the opposite direction in the wooden ceiling screwed screws on the wooden ceiling.

An embodiment of the invention provides receptacles for Armierungsstäbe to the anchors. The recordings may be, for example, slots or notches, possibly even holes. The recordings can also be in cross-section Ω-shaped bracket or grooves for snapping a reinforcing rod. Reinforcing bars attached to or in the receptacles are held by the anchors at a distance above the timber ceiling when the anchors are arranged with the anchor connector in the intended manner on the timber ceiling. As a result, reinforcing bars or reinforcing mesh can be arranged at an intended height above the timber ceiling in a concrete layer cast on the wooden ceiling. Armierungsstäbe or reinforcements are also referred to as reinforcing bars or reinforcements. They are usually made of steel, are poured into the concrete and increase its tensile strength, depending on the position and arrangement of its flexural rigidity and torsional rigidity.

An embodiment of the invention provides one or more supports for a reinforcement of the concrete, ie in particular for the placement of reinforcing bars or a reinforcing grid. The reinforcement can rest loosely on the support, or the support can also be designed, for example, to snap in the reinforcement or as a hole for inserting a reinforcing rod. The list is exemplary and not exhaustive. The support holds a reinforcement lying on it with a distance above the timber ceiling or generally the ground on which the wood-concrete connection kit is or will be, so that the reinforcement is completely enclosed by the concrete and concrete between the reinforcement and the Wooden ceiling or generally located underground.

Preferably, the support for the reinforcement is at least as high as the anchor. By this is meant that the armor resting on the support is at least one level above the timber ceiling or generally above the ground on which the wood-concrete connection kit is placed, or becomes as high as a maximum height of the anchors the wooden ceiling or in general the underground. This avoids that the anchors are in the way when placing the reinforcement.

An embodiment of the invention provides a particular straight L-profile, U-profile or C-profile with in particular over a length of the profile constant cross section as an anchor connector. Here is a leg of the L-profile or one of the two Legs of a U-profile connecting web provided for fixing on the timber ceiling or generally on the ground, and the one or more of the wooden ceiling or the ground generally upstanding leg of the profile serve as a support for the reinforcement. Under a C-profile is to understand a U-profile, the legs are lower than its bridge is wide.

On one of the base side 7 of the armature 4 far end, the screw holes 6 have a cylindrical countersinking, which merge at its base with a frusto-conical taper into a smaller diameter of the screw holes 6. The cylindrical counterbore forms a plug-in receptacle 8 for inserting a cladding tube 9, and the taper an abutment 10 for a screw head 11 of a screw 12 for fixing the anchor 4 on the timber ceiling 2. In the median plane between the two screw holes 6, the anchor 4 has a groove as a receptacle 13 for reinforcing bars 14 on. In FIG. 1 are the grooves that form the receptacles 13 for the reinforcing bars 14, drawn with dashed lines. Material and geometry of the anchor 4 are not mandatory for the invention, other materials and geometries than those described are possible. Likewise, the armature 4 may have only one screw hole 6 or more than two screw holes 6 and / or the screw holes 6 may have an angle other than 45 ° to the base side 7 of the armature 4, for example, also perpendicular to the base side 7. The screw holes 6 may be provided at locations other than the anchor 4 as described.

The anchor connector 5 is a straight sheet metal strip, which in FIG. 2 drawn as an item in view. The anchor connector 5 has at equal distances from each other parallel, strip-shaped elevations 15 with dovetail-shaped cross-sections, which are arranged transversely to the anchor connector 5. The dovetail-shaped elevations 15 of the anchor connector 5 interact with corresponding grooves 16, which are also dovetail-shaped in cross-section, in the base sides 7 of the anchors 4. The elevations 15 and the grooves 16 form fastening means 17, by means of which the anchors 4 are connectable to the anchor connector 5. In the exemplary embodiment, the fastening devices 17 are plug connectors, with which the anchors 4 can be plugged and pushed onto the anchor connector 5 by being pushed transversely to the anchor connector 5. The anchors 4 are by hand can be connected to the anchor connector 5 without tools. There are other connectors, also with other plug-in direction and other fasteners as connectors for connecting the armature 4 with the anchor connector 5 possible. The fasteners 17 hold the anchor 4 in a straight line at equal intervals and with the same or - if the armature 4 is rotated by 180 ° about a vertical axis on the anchor connector 5 - opposite orientation on the anchor connector 5. The two screw holes 6 of Anchor 4 connected to the anchor connector 5 are in two parallel planes perpendicular to the armature connector 5 forming sheet metal strips and extending in its longitudinal direction, equal or opposite obliquely to each other. The receptacles 13 for the reinforcing bars 14 forming grooves of the anchor 4 are aligned.
