Definitions

  • the invention relates to a reinforcement connection according to the preamble of claim 1 and to a holder according to the preamble of claim 7.
  • Reinforcement connections of this type are known in a wide variety of designs and are used in a particularly simple manner to attach a concrete component, e.g. Connect another concrete component (e.g. concrete wall) in such a way that this connection area is bridged by a connection reinforcement in the concrete.
  • the reinforcement connection is fastened with its box-like storage element to the inner surface of the formwork of the concrete component to be created first.
  • holders have already been proposed for this purpose, which fix or hold the respective storage element on the formwork using permanent magnets.
  • additional holding elements bent from sheet metal strips are required, which leads to an arrangement which is relatively complicated to handle.
  • the invention has for its object to show a reinforcement connection and access holder, which enables the reinforcement connection to be fastened to a steel formwork in a substantially simplified manner.
  • a reinforcement connection according to the characterizing part of claim 1 and a holder are formed according to the characterizing part of claim 7.
  • the block-like or strip-like body forming the holder is preferably formed on a third circumferential side also adjoining the first circumferential side and opposite the second circumferential side in such a way that the distance between the second and third circumferential sides decreases with increasing distance from the first circumferential side. This makes it possible to remove the holder from the concrete of the first concrete component without difficulty.
  • 1 is the storage element of a reinforcement connection made of sheet steel by bending.
  • the storage element 1 has a dovetail-shaped cross section, which is formed by the base 2 and the two legs 3 and narrows towards the side opposite the base 2.
  • the connecting parts forming sections 4 'of the reinforcing bars 4 are housed, which are passed through the floor 2 with their other sections 4 ⁇ forming the anchoring areas.
  • each leg 3 has, at a distance from the associated bend 6, a triangular bead 7 protruding beyond the outside of the respective leg and extending in the longitudinal extent of the storage element 1.
  • the reinforcement connection is arranged in the interior of a formwork shown by formwork walls in such a way that it lies with the cover 5 against the inner surface of a formwork wall 8.
  • the formwork wall 8 is part of a reusable steel formwork.
  • Holders 9 in the form of permanent magnets are used in the embodiment according to FIG. 1 to hold the reinforcement connection or the storage element 1 on the formwork wall 8.
  • Each permanent magnet or holder 9 is shaped such that it has a cross section in a cross-sectional plane perpendicular to its longitudinal extent, which is characterized by the following cross-sectional and circumferential sides:
  • the circumferential side 12 has a recess 13 with two surfaces, specifically with the surface 14 adjoining the circumferential side 12 and with the surface 15 adjoining the surface 14.
  • the surfaces 14 and 15 run parallel or perpendicular to the circumferential side 10. It is essential, however, that the recess 13 forms a projection 14 'with the surface 14 as a contact surface which engages behind the respective bead 7 of the storage element, so that the Storage element 1 can be attached to the formwork wall 8 with the aid of the holder 9. It goes without saying that preferably at least one holder 9 is provided on each longitudinal side of the storage element 1.
  • the holders 9 can be removed from it, specifically by unscrewing them in the opposite direction of arrow A.
  • the latter is carried out using a suitable tool which can be attached to a tool engagement surface formed on the peripheral side 10.
  • the block-like or strip-like holder is designed continuously as a permanent magnet.
  • the holder 9 from a non-magnetic material, for example from plastic, in which case permanent magnets are then embedded in the material of the holder, preferably in such a way that they are essentially exposed on the peripheral side 10 of the holder 9 Form magnetic pole or are covered only with a thin layer of the material of the holder 9.
  • the nose-like projection formed on the peripheral side 12 and the surface 14 is either continuous over the entire length of the holder 9 trained, or but interrupted, so that the surface 14 is a continuous contact surface or a correspondingly several contact surface for the thickness 7 are formed.
  • Fig. 2 shows an embodiment which differs from the embodiment of Fig. 1 essentially in that each holder 9a has a nose-like projection 16 cooperating with the bend 6 of the storage element 1 on its peripheral surface.
  • Each holder 9a has a cross-section in a cross-sectional plane perpendicular to its longitudinal extent, which is characterized by the following cross-sectional and circumferential sides:
  • the nose-like projection 16 is formed, namely from the portion 19 'of the circumferential side 19 and from the adjoining circumferential side 21.
  • Der Section 19 ' which forms the side of the projection 16 which faces away from the peripheral side 17, forms an angle with the peripheral side 21 which is approximately the same, slightly smaller than the angle which the bend 6 with the adjacent partial region 3' of the respective leg 3 includes.
  • the projection 16 is, for example, a continuous projection that extends like strips over the entire length of the respective holder 9 extends. Instead of a single projection 16, two or more than two projections 16 can also be provided offset with respect to one another in the longitudinal direction of the holder 9.
  • Each holder 9 consists of a housing 22 which is made of ferromagnetic material and has the shape described above, including the at least one projection 16, on its outer circumference. At least one recess 23 is provided in the housing 22, which is open to the flat peripheral side 17 and into which a permanent magnet 24 is inserted such that it has a pole in the region of the open side of the recess 23 and with its other magnetic pole in the region the closed side of the recess 23 is provided.
  • the permanent magnet 24 is spaced from the side surfaces of the recess 23.
  • the space thus formed between the permanent magnet and the material of the housing 22 is filled with plastic 25 or another mass which has a low magnetic conductivity compared to the material of the housing 22.
  • a plurality of recesses 23, each with a magnet 24, or one or more slot-shaped recesses 23, each with at least one, preferably elongated magnet 24, are provided in the longitudinal direction of the holder.
  • the holder 9 Due to the magnetic field generated by the at least one permanent magnet, the holder in question and thus also the storage element is held on the inner surface of the formwork wall 8.
  • the holder 9 has the advantage, among other things, that the respective housing 22 forms a magnetic pole piece, and thus the magnetic field of each permanent magnet 24 is closed over a short distance in the area of the peripheral side 17 via the formwork wall 8, so that a permanent magnet 24 has a given thickness optimal hold results.
  • the holder 9 can of course also be produced in a manner similar to the holder 9a with a housing forming a pole piece. Regardless of the particular shape and other design of the holder 9 or 9a, it is expedient to provide this on its outer surface with a coating which counteracts integration into the concrete.
