Definitions

  • the invention relates to a wood-concrete connection kit with the features of the preamble of claim 1.
  • 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.
  • 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.
  • 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.
  • anchor is meant a component castable with concrete, which due to its shape and possibly its surface finish has hold in the concrete.
  • the anchor 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.
  • 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.
  • the wood-concrete connection kit 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.
  • the anchor by means of fastening devices without tools, for example by plugging, connectable to the anchor connector.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • one side of the anchor connector is provided with a self-adhesive layer of adhesive, which is covered for example with a protective film.
  • the anchor connector may have mounting holes.
  • 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.
  • an elastic base for example an elastic foam layer or an elastomer layer
  • 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.
  • 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.
  • 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 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.
  • wood-concrete connection kit 1 for producing a shear-resistant composite between a wooden ceiling 2 and a cast on the wooden ceiling 2 layer of concrete or a finished laid on the wooden ceiling 2 layer of concrete.
