Definitions

  • the invention relates to a kit for producing a transport anchor, in particular for cavity walls or double or multiple concrete walls, each with opposing concrete shells.
  • the invention further relates to an arrangement of lifting anchor shackle with this kit.
  • the invention also relates to a method for producing a transport anchor and the use of an unwinder for a method for producing a transport anchor.
  • Double walls and other precast concrete components are prepared in precast concrete plants for use on construction sites.
  • Transport anchors are required for transport to the construction site, which are cast into the concrete.
  • the transport anchors for transporting double walls can be bent from steel bars or coiled steel, for which bending machines are often available in precast concrete plants.
  • bending machines are often available in precast concrete plants.
  • self-bent transport anchors do not meet the legal requirements for the necessary operational safety or security against being pulled out due to the lack of reinforcement of the bent products.
  • the bracing of the transport anchors can be improved by attaching additional struts to the steel that has been pre-bent with automatic bending machines.
  • transport anchor filament anchor
  • the transport anchor essentially comprises a clevis and a crossbar or a cross brace.
  • the parallel, opposite ends of the load bracket serve as anchoring legs for embedding in concrete in a concrete shell. They are connected to one another by a center section of the yoke that is generally curved once or several times and are held apart or at a predetermined distance from one another by the cross brace. This stiffening is intended to prevent the anchoring legs from contracting and tearing out of the concrete shells when the wall is lifted.
  • the cross brace is movably attached to the anchoring legs. To determine the position, locking is carried out with a detachable holding device.
  • the DE 10 2016 119352 A1 provides a transport anchor with a ready at which the crossbar is made of concrete.
  • a fixing element can connect the anchor legs to one another, preferably by welding. This fixing element enables the anchoring legs to be shortened or prevents them from floating up.
  • the U.S. 3,971,552 A relates to a clamping device for pipelines, which has a support with V-shaped clamping jaws.
  • the KR 102 008 511 B1 relates to a clamping device for pipelines, which has a support with a curved clamping jaw.
  • a disadvantage of these clamping devices is that the clamping process is time-consuming and thus also lengthens the assembly time, which can make a mass product unprofitable.
  • kit according to claim 1 an arrangement of kit and lifting anchor shackle according to claim 7, a manufacturing method according to claim 10 and a use according to claim 11.
  • Advantageous embodiments are claimed in the dependent claims.
  • the invention relates to a kit for producing a transport anchor, in particular for cavity walls or double or multiple concrete walls, each with opposite concrete shells.
  • the transport anchor has a clevis with one or more anchoring legs, each associated with a concrete shell or concrete wall, and a cleat middle section, via which the two anchoring legs are connected to one another.
  • external load handling and/or transport means can be coupled or engaged with the middle section of the yoke.
  • the manufacturing process becomes more efficient with the kit according to the invention.
  • a manufacturer of precast concrete parts who needs reliable transport anchors for transporting the precast concrete parts can provide the clevis themselves on their own bending machines and then use a purchased cross brace.
  • the clevis of the transport anchor can be pre-bent with the bending machine.
  • a kit according to the invention with a cross brace, a holding device and a fixing device for manual and/or automated assembly of the holding device and cross brace on the clevis is required.
  • a worker can precisely assemble a tested transport anchor for double walls without any special prior knowledge or tools.
  • a stiffening cross brace the safety of the self-bent transport anchor can be improved so that it can meet legal requirements.
  • the bar steel or the coiled steel for the clevis and the cross braces can be transported separately and be stored separately at the final assembly site.
  • the space required for the separate storage of cross braces and unbent steel is significantly reduced compared to a fully assembled transport anchor.
  • a truck with bar steel or also with coiled steel transports at least 25 tons.
  • a truck with finished double wall anchors could transport a maximum of 10 tons, then the truck is already fully loaded.
  • the construction kit which enables safe transport anchors to be manufactured on site in the precast concrete plant, can relieve the traffic routes due to the reduced need for transport.
  • the kit according to the invention enables a cross strut to be fitted in a clevis without welded joints.
  • the kit's retaining device also prevents or makes it difficult to slip along the anchoring legs. There is no longer any need for relatively complex welded joints or other materially bonded joints. Welded joints are known to be weak points, even in the case of lifting anchors that are manufactured in accordance with standards (cf. E DIN EN 13155). Welding should therefore generally be avoided with operationally reliable anchors.
  • a holding device which comprises or encompasses an anchoring leg assigned to a first concrete shell and an anchoring leg assigned to a second concrete shell, the holding device having a frictional holding contact or other adhesive contact or adhesive contact with the anchoring leg assigned to the first concrete shell and/or that assigned to the second concrete shell Anchoring legs formed.
