Definitions

  • the invention relates to a concrete beam which has a T-profile at least on the upper part.
  • Such beams are manufactured in standard sizes, with reusable formwork being provided for each size.
  • a box-shaped concrete profile is formed on the upper flange of the T-profile.
  • the tipping stability is also increased.
  • Another advantage is the fact that the web height remains relatively small, so that the web thickness does not have to be increased unnecessarily. Furthermore, compacting with the vibrating bottle is achieved very cheaply.
  • the box is hollow on the inside and provided with a lost formwork, in particular filled with rigid foam.
  • a lost formwork in particular filled with rigid foam.
  • rigid foam instead of the rigid foam, another formwork made of sheet metal, for example, can also be used.
  • the method for producing the concrete girder according to the invention is preferably carried out in several sections, the girder being first concreted without a box section, then formwork surfaces on both sides of the top layer and one between them lost formwork can be attached and then the box section is concreted.
  • the drawing shows an embodiment of the invention, namely the cross section through a double-T-shaped concrete beam.
  • the beam 1 is a standard beam with the web 2, the beam 3 and the top 4.
  • a box-shaped hollow section 5 is concreted on the top 4, the inner cavity 6 of which is filled with rigid foam.
  • the standard support 1 is first pre-concreted, whereupon the rigid foam 6 is then placed on the top cover 4 and, as shown in broken lines, 4 simple formwork boards 7 are arranged on the side of the top cover. Then the hollow box section 5 is then concreted onto the upper block 4.
