Definitions

  • the invention relates to a set for joint construction for trafficable concrete surfaces of concrete slabs, which are produced on site, with simultaneouslyzargen for the enclosure of adjacent concrete slabs, each having a specific for covering the vertical end faces of the concrete slabs, substantially vertically oriented central leg, the top in a horizontally angled upper end leg and down into a likewise horizontally angled lower Aufstandsschenkel.
  • the invention comprises navigable traffic areas made of locally produced concrete slabs and in particular a device for bridging and forming dilatation and contraction joints in order to dissipate the resulting stresses by thermal deformation in the concrete covering and thereby avoid damage such as cracks and flaking.
  • the peculiarity consists of the multifunction of relatively thin closing frames that encircle the concrete slabs.
  • Such joints constructions are required for trafficable concrete pavement surfaces, for example, roads, airfields, aprons, terraces, roofs and especially for parking decks on roofs. Since the traffic areas are exposed to the weather, in particular extreme temperatures of + 60 ° C to -30 ° C especially on the surfaces in summer and in winter, measures must be taken to compensate thermally induced changes in length. In particular, when the concrete slabs are made on thermally insulated and sealed roof surfaces, they must be able to expand and contract independently without transferring stress to the underlying seal. For this purpose, between the concrete slabs circumferentially arranged dilatation and Contraction joints provided.
  • joint chambers must be closed elastically, so that no sand, dirt, water or snow can penetrate, which could hinder a tension-free deformation of the concrete slabs and can lead to cracks and flaking. It is therefore necessary to permanently and safely close these joint chambers with an elastic material.
  • Object of the present invention is to improve a joint construction of the type mentioned above for drivable traffic areas made of concrete slabs, so that at low cost production a long service life is guaranteed and as possible no maintenance costs.
  • the solution according to the invention is that the closing frames are provided in the upper region of the central leg near the drivable surface of the concrete slab, each with a horizontal, lateral claw groove, the open sides of the claw grooves of adjacent concrete slabs opposite to each other at the distance of the joint width provided between the concrete slabs joint chamber , and that the joint chamber is covered by an expansion joint profile seal in the form of a hollow chamber profile made of elastic material substantially flush with the drivable surface of the upper end leg of the concrete slabs, wherein the expansion joint profile seal projects down into the region of the claw grooves and laterally projecting anchoring lips which in engage the claw grooves. As a result, it is permanently secured in their position.
  • the claw grooves according to the invention are formed in a simple and cost-effective manner in the fashionzargen.
  • the expansion joint profile gasket is produced as an extruded profile in a simple manner and inexpensively as an endless strand and prefabricated for the object-specific use in the factory to the concrete slab size and delivered to the site.
  • the expansion joint profile seal is pressed in a simple manner from above into the joint chambers, wherein the hollow chamber profile reducing the width of the profile sealing strand by lateral Squeezing allows, so that the laterally projecting anchoring lips are first pressed together so far that they fit into the narrow joint chamber inside to expand laterally when reaching the claw grooves laterally into the claw grooves and dig.
  • the expansion joint profile seal is completely securely anchored in the claw grooves of theinzargen within the joint chamber and it remains even under extreme stress by moving vehicles or by different weather conditions.
  • This joint construction can now work as a dilatation and contraction joint, that is, the joint chamber can be narrower or wider, without the expansion joint profile seal is too loosened or excessively squeezed, because the hollow chamber profile allows large strains and compressions and always remains safe through the lateral anchoring lips anchored in the claw grooves.
  • the invention therefore ensures that no dirt, sand or other debris can penetrate into the joint chambers and cause damage there, for example by filling the joint chamber with material which restricts or prevents the expansion of the concrete slabs and would then lead to deformations and damage to the concrete slabs ,
  • the introduction of the expansion joint profile gasket requires no complex means or steps and can therefore be carried out very inexpensively.
  • To introduce the expansion joint profile seal in the joint chamber thus requires only a small force.
  • the expansion joint profile seal is compressed laterally so that it can be inserted into the joint chamber.
  • the lower sloping leg is adapted to the sloping surface of the lateral anchoring lip of the expansion joint profile seal, so that the anchoring lips can slide unhindered into the claw grooves and dig into it.
  • the upper leg of the claw grooves is aligned horizontally, so even with strong upward forces on the expansion joint profile seal no force components that compress the expansion joint profile seal and could affect their solid anchorage in the claw groove.
  • the meetzargen made of chrome-nickel steel or plastics. This measure protects them against corrosion in the long term. In addition, these materials facilitate the shaping of thebetweenzargen, in particular the formation of the claw groove according to the invention.
  • a concrete stop film is attached to the undersides of the lower horizontal uprising legs of the complicatzargen, which insulates emerging cavities on uneven roof surfaces and Lunken so that the liquid concrete can indeed flow into the cavities below the treads, but not in the expansion joint chamber to be kept clear.
  • the concrete stop film is preferably glued to the lower tread leg of the complicatzarge
  • a further advantageous embodiment of the invention provides that Zargeneck,e are arranged at the corners of the rectangular or square concrete slabs, which are formed by contzargen by miter cuts and notches. Except for the latter features, these Zargeneck,e do not differ from circuitzargen, which has bent at right angles.
  • the Zargeneck,e thus consist of a bent at right angles modified central leg and miter cuts each divided into two sections withschekel and Aufstandsschenkel, each meeting at right angles.
  • the Zargeneck,e are designed as well as the document.
  • the four ends of the central moldings are glued to the adjacent expansion joint gaskets.
  • the stability of the connection can be further improved by the central molding is provided at its ends with pins, which serve to connect the central molding with adjacent sealing gasket profile gaskets.
  • the invention also includes a configured according to the features described above, consisting of two such conversationzargen Zargenbauteil for a trafficable traffic area made of concrete, because the core of the invention manifests itself in the design of Zargenbaumaschinemaschine, especially in the Klauennuten.
  • the Zargenbauteil invention is characterized by the fact that two are initially connected as an assembly aid by means of plastic screws preferably made of polyamide firmly together, so that their central leg and the claw grooves are opposite, with inserted spacers guarantee the exact distance of the joint chamber.
  • the closing frames are thus connected together in a position that they later occupy in the trafficable traffic area, whereby they can be installed in the planned plate and joint grid assembly stable.
  • the Zargenbaumaschine be placed on site at the appropriate place and connected to each other.
  • suitable butt connectors are provided which provide a simple connection by snapping two Allow frame lengths. Only unevenness of the footprint must be compensated by underlying wedges.

  • the spacers can also be made of plastic.
  • the invention also includes prefabricated central crossing components, in which four Zargeneck GmbHe are connected to each other, so that their central leg and the Klauennuten face each other, with inserted spacers guarantee the distance of the joint chambers.
  • the central crossing components are delivered pre-assembled to the construction site and placed on the floor according to the dimensions of the concrete slabs to be cast.
  • the straight sides between the central crossing components are then filled with frame members which are adapted in length to the dimensions of the concrete slab, whereby concrete concrete frames are produced with liquid concrete.
  • the resulting formwork are poured with liquid concrete, making sure that no concrete gets into the joint chambers.
  • the spacers and the plastic screws can be pulled out of the joint chambers or cut out so that the joint chambers are then completely free of material which could impair their purpose.
  • the expansion joint profile seal is pressed from above into the joint chamber until it engages and is securely anchored.
  • the invention also includes a central molding, which corresponds in shape and function of the expansion joint profile seal. It is designed to accommodate the same deformation as the expansion joint profile seal.
  • the central molding is formed cross-shaped with four equal-length legs, the legs ensure a positive connection to adjacent expansion joints profile seals.
