Definitions

  • the invention relates to a holding device with the features of the preamble of claim 1, as is known for example from US-A-4000 591.
  • a box-shaped or box-shaped holder of the anchor is proposed, the cylindrical, conical transition anchor foot not having to be inserted into the receiving box from above, as in the subject of the application, but from the side.
  • the holding device 1 according to the invention shown in the drawing is intended for pouring into concrete or the like, in particular concrete slabs, and has a transport anchor 2 and a holding foot 3, which can be placed on the formwork floor or fastened to a formwork wall before the concrete is poured.
  • 4 holes 8 are formed in the base plate, through which the holding foot 3 can be fixed immovably on the formwork wall by means of nails, wire, screws or similar fastening parts.
  • a recess 9 is also formed with an insertion opening 10 for the transport anchor 2.
  • the insertion opening 10 is preferably significantly larger than the cross section of the transport anchor 2 and adjoins the insertion opening 11 of the recess 9.
  • the holding foot 3 ⁇ is designed essentially as a bent wire part and has two supports 19 formed from wire and a U-shaped wire bracket (20) which is preferably fastened to the two supports 19 by welded connections.
  • the support 19 has a U-wire bracket 20 receiving cross strut 21, which U-wire bracket 20 forms the base part, the ends of which are bent approximately at right angles, so that the legs 6 'are formed, onto which the plastic caps 7 are pushed.
  • the holding feet 3.3 ⁇ Due to the advantageous design of the holding feet 3.3 ⁇ , there is on the one hand large free spaces for void-free pouring or pouring with concrete, and on the other hand, the holding feet 3.3 ⁇ allow through the different and striving in different directions bent parts a good anchorage in the concrete, so that an absolutely firm hold of the holding device 1 is ensured in the concrete. Another advantage is that the holding feet 3.3 ⁇ with the obliquely flared side walls 5 and legs 6.6 ⁇ stacked tightly one above the other and can thus be stored and transported in an extremely space-saving manner.
