Definitions

  • the invention relates to a reinforcement for concrete structures on structural joints in one and / or two concrete components, which reinforcement has at least one receptacle for a joint tape made of rubber, plastic or the like.
  • construction joints are due to the specific construction of a component, e.g. B. building or a bridge, whereas the expansion joints are required to compensate for the expansion or contraction of components that are due to the different temperatures.
  • an expansion joint is provided at intervals of 24 to 25 m.
  • rubber-elastic tapes so-called joint tapes, are arranged in these joints.
  • joint tapes For economic reasons, these joint tapes must already be inserted in the formwork for the concrete component.On the one hand, easy assembly of the joint tape is desired and fixing the position of the joint tape while covering it with concrete is expedient, and at the same time an injury to the joint tape, such as holes through it, which are used to attach the same thing to the reinforcements with a wire rope. Another difficulty is that part of the joint tape, u. between the one that should protrude into the other structural component to be manufactured later, on the one hand must not be embedded in the first component and on the other hand should not be injured either.
  • a joint insert for concrete construction is known from DE-B-1 259 546, the joint strip having webs running in the center and on both sides thereof, which are arranged in the region of the subsequent joint. These webs carry expanded metal formwork for the joint to be formed.
  • Such a construction simplifies the formwork work, since expanded metal is provided instead of wooden cladding, a position fixing for an exact orientation of the joint tape, based on the normal formwork, cannot be achieved here, since there is no additional support for the joint tape, so that undesirable warping or od . The like.
  • a further joint tape is known from CH-A-559 294 and US-A-3,884,000, which has a reinforcement made of steel bars at its two ends provided parallel to the longitudinal extension.
  • steel brackets are provided, each of which engages in corresponding recesses in the region of the longitudinally extending steel reinforcements and which are simultaneously fastened to the steel reinforcement to be provided in the concrete with a solder wire.
  • such a joint tape holder has the disadvantage that such brackets are provided at relatively short intervals, by means of which the transverse extent of the joint tape is ensured, which ensures that Reinforcements must be fastened with a wire wire, so that an exact positioning of the joint tape is possible, but there is a particularly high amount of work.
  • brackets are provided at relatively short intervals, by means of which the transverse extent of the joint tape is ensured, which ensures that Reinforcements must be fastened with a wire wire, so that an exact positioning of the joint tape is possible, but there is a particularly high amount of work.
  • the required number of fixings for the joint tape is not provided, so that in spite of this construction there are inexactly oriented joint tapes in daily use.
  • a joint formwork element is known from EP-A-0 532 908, which has a basket-like structure made of a steel grid mat.
  • the joint tape is to be added to this basket.
  • approximately normal bracing angles are welded, which carry the actual formwork elements made of expanded metal.
  • Such a formwork element solves the task of precisely positioning the joint tape before the actual concreting process, there are considerable disadvantages.
  • a large number of angles must be welded on both sides to the basket-like structure that is to carry the joint tape, so that the formwork elements can be positioned exactly and at the same time are able to absorb the pressure exerted on them by the flowable concrete.
  • the object of the present invention is to provide a reinforcement for concrete structures that allows a simple and quick positioning of a joint tape, which due to its constructive design allows a particularly labor-intensive covering of the joint tape with concrete and that at the same time can be created particularly easily and with little effort.
  • the reinforcement according to the invention in particular made of steel, for concrete structures on structural joints in one and / or two concrete components, which reinforcement has at least one receptacle for a joint band bridging the joint made of rubber, plastic or the like with a large number transversely to the longitudinal direction of the Joint tape arranged bracket, which are connected via reinforcements oriented in the longitudinal direction of the tape, wherein on both sides for receiving formwork elements, which in particular have perforations, for. B.
  • expanded metal plates consists essentially in that the brackets directly and / or in the longitudinal direction of the joint tape further reinforcements, which are directly connected to the brackets, carry the formwork elements and that the brackets with the receptacle and the area, which has the formwork elements and / or the additional reinforcement that supports the formwork element (s) is formed in one piece.
  • a reinforcement is created which on the one hand carries a joint tape and on the other hand has formwork elements for the joint, so that the arrangement of the joint tape can be carried out together with the formwork elements.
  • bracket carry the joint tape directly or with the mediation of a further reinforcement running along the joint tape
  • a particularly simple bracket is given, which at the same time allows a simple aerodynamic design, so that there is also a reinforcement that is particularly simple and with low workload can be produced, with an exact positioning of the formwork is guaranteed together with the joint tape.
  • a reinforcement can be designed so fluidly in terms of flow technology that a desired full-surface area is required during the filling process with concrete Wrapping the joint tape in the area to be concreted can be easily achieved.
  • the joint tape can be fixed stationary and exactly in terms of work, depending on the distance between the U-shaped areas of the brackets. if necessary, the joint tape can also be inserted after positioning the reinforcement on site. Furthermore, it is ensured that the flow resistance for the liquid concrete can be kept extremely low, since only the U-shaped or V-shaped regions of the bracket represent flow baffles.
  • the U-shaped or V-shaped area of the receptacle corresponds essentially to the transverse extent of the joint tape, the same can be held exactly in position not only in the longitudinal direction but also in the transverse direction, so that the joint tape bends during work are particularly easy to avoid.
  • bracket has on both sides of the U-shaped or V-shaped area at least one other U-shaped or V-shaped area oriented opposite to the U-shaped or V-shaped area with a further leg that is transverse to the legs of the U's or V's runs around, there is an approximately threefold lyra loop through the steel reinforcement, which can be obtained by a simple bending process, with the middle lyra loop, i.e. the middle U-shaped bracket, used to hold the joint tape and the other legs either directly or over lengthways reinforcement of the joint tape can carry the formwork elements.
  • the U- or V-shaped area corresponds only to a part of the transverse extent of the joint tape and has legs at the ends of the U's or V's that run transversely to the joint tape and which have the formwork elements, then an extraordinarily simple reinforcement is provided, which is particularly easy to produce can be guaranteed and sufficient protection of the joint tape for certain requirements.
  • another receptacle is then applied at the same time which, like the first receptacle, only supports the formwork on one side.
  • the further reinforcement can then be fastened to the first reinforcement with solder wire, so that an exact positioning of both the joint tape and the reinforcement on structurally difficult joints is ensured with the simplest means.
  • the bracket has an approximately U-shaped or V-shaped area which carries legs which are arranged in the interior of the U's or V's, with a receptacle for the joint tape being formed with the two legs, a receptacle for the joint tape can be provided are formed, the z. B. with a vertical orientation of the joint tape up and down is open, so that on the one hand the positioning of the joint tape can be given by the further reinforcement and furthermore a simple complete flow around the joint tape can also be completely guaranteed in the lower and upper region of the joint tape.
  • this reinforcement provides a particularly simple construction of a construction joint.
  • the joint tape can be held in the receptacle by a clamp seat, this clamp seat can be done before the reinforcement is installed, so that the reinforcement can be positioned together with the joint tape on the one hand, and on the other hand there is also the possibility of re-installing the joint tape Insert the steel reinforcement into the receptacle and then fix the joint tape by deforming the bracket.
  • the bracket 7 is approximately lyre-shaped and has a receptacle in the form of the U-shaped area 8, which receives the joint tape 9 in its entirety. This U-shaped area is adjoined by two further reversely oriented U-shaped areas 10, from which legs 11 strive. These legs are provided approximately in the central area of the U-shaped area 8.
