Definitions

  • the invention relates to an assembling device and a method for assembling anchor bolts. More particularly, the invention relates an assembling device and a method for assembling anchor bolts in a concrete reinforcing mesh.
  • Anchor bolts are commonly used fasteners for attaching structures, such as wall elements, for example, to a concrete foundation. Different types of anchor bolts are used, but typically all of them consist of a threaded end, to which a nut and washer can be attached for the external load.
  • a common apartment building comprises a lot of anchor bolts.
  • one store having a quite small area in a building may contain about 100 or more anchor bolts.
  • assembling anchor bolts in a concrete reinforcing mesh before casting concrete is very laborious and time consuming project.
  • anchor bolts are assembled by welding or tying due to a lack of better assembly method.
  • Welding or tying anchor bolts in a concrete reinforcing mesh are very slow procedures requiring lot of working hours, which naturally increases costs. Also, the outcome may not be satisfactory in many cases, but anchor bolts may come off or get into a wrong position during casting.
  • underfloor heating pipes may cause troubles and increase costs.
  • the underfloor heating pipes must be assembled in concrete reinforcing mesh before anchor bolts and welding anchor bolts can easily break these pipes. Replacing and/or repairing are laborious and time consuming project. Due to this many builders have given up assembling underfloor heating, which on the other hand may slow down and hinder drying of concrete. At the worst, this may cause damages to the building because of the moisture in structures.
  • An assembly device for anchor bolts according to the present invention is characterized by the features of claim 1.
  • an assembly device for an anchor bolt comprises a fastening part for fastening the assembly device in a concrete reinforcing mesh, and supporting part supporting an anchor bolt in the assembly device, wherein the fastening part and supporting part are connected together in a substantially perpendicular position.
  • the fastening part has a form of centric shapes for enabling easy fastening of the assembly device.
  • Centric shapes such as, but not limited to circles, ovals, squares, rectangles, stars or others shapes, may provide a firm structure to the assembly device for keeping it in right position during casting, but still leaving good space for the user to easily fasten the assembly device by hand or by using a fastening tool in concrete reinforcing mesh.
  • the supporting part comprises at least one hanger part for supporting an anchor bolt in the device.
  • the anchor bolt may be firmly supported in the assembly device and it may better stay in its position during casting.
  • the supporting part comprises means for adjusting the height of the assembly device.
  • This embodiment can be advantageous for using one assembly device for different types of anchor bolts, especially when the height of the anchor bolt varies.
  • this embodiment provides means for adjusting the depth that anchor bolt will sink in concrete in case the concrete reinforcing mesh or the concrete foundation level varies, for example.
  • the assembly device comprises locking means for locking an anchor bolt in the assembly device.
  • This embodiment may enable a user to prepare the assembly by inserting anchor bolts in the assembly devices beforehand and transfer them to an assembly location without a fear that the anchor bolts will detach from the devices, which could cause extra work.
  • by locking the anchor bolts in the assembly device it may provide more secure positioning for the anchor bolts during casting.
  • the assembly device further comprises a removable protecting part for protecting threads of the anchor bolt during casting. This embodiment helps the casting process, when there is no fear of spoiling the anchor bolts with concrete.
  • At least the protecting part has a high-visibility color for helping to locate anchor bolts in the concrete foundation after casting.
  • Adding a high-visibility color to the assembly device may also help workers on a foundation site to locate anchor bolts even in difficult circumstances, such as among snow, and not to accidently step on them or kick them.
  • a method for assembling anchor bolt in concrete foundation according to the present invention is characterized by the features of claim 8.
  • a method for assembling anchor bolt in a concrete foundation having an assembly device comprises at least following steps of:
