  • the two wall strips are connected together in parallel and at a distance from one another by a series of transverse bars which extend transversely across the distance between the wall strips.
  • the cross bars are bent at the mutually facing edges of the wall strips, so that, for example, results in a U-shaped cross-section whose vertical legs are formed by the wall strips and whose connecting leg forms the open bottom portion of the formwork element.
  • the open floor area allows concrete, with all its components, to pass unhindered and connect to the underlying structure.
  • the invention has for its object to provide a simple and inexpensive to produce formwork element.
  • the inventive design a formwork element is created, which is simple and inexpensive to produce.
  • the concrete permeable openings ensure that concrete with all its constituents can pass through the floor area substantially unhindered, so that there is no segregation of the concrete at the interface of the floor area in the area of the openings coarse constituents take place in the interior and thus a monolithic connection with an extension of the waterway (WU) through the floor area is possible.
  • WU waterway
  • the formwork element according to the invention may be provided in a simple manner with a water barrier, which is connected by means of a sloping stiffening support to the bottom area.
  • the inclined stiffening support is expediently installed so that the stiffening support and the water barrier device act as a triangular support, causing a stiffening of the entire formwork element, so that the formwork element is stiffened in a way that also easily transported a greater length (up to 10 m) , eg can be lifted by a crane without the formwork element is bent or damaged.

  • the stiffening beams 13a, 13b extend obliquely to the bottom region 4, but also run obliquely to the walls 2, 3 and the joint plate 12.
  • the stiffening support 13a, 13b with the bottom portion 4 form an angle between 30 and 60 °.
  • the stiffening beams 13a, 13b are preferably strip-shaped and permeable to all constituents of the concrete, so that they do not hinder the filling of the concrete between the walls 2, 3.
  • the stiffening carriers are preferably so-called D-carriers (single carriers) and consist of bar material.
  • Each stiffening beam 13a, 13b includes a top chord 14a in the form of a metal bar, a bottom chord 14b in the form of a metal bar, and a diagonal 14c in the form of a metal bar connecting top chord 14a and bottom chord 14b.
  • the diagonal 14c is preferably a wave-shaped bent rod, which is connected in its wave troughs and wave crests with each of the upper and the lower chord.
  • the stiffening carriers are fastened, preferably welded, to the bottom region 4, preferably in the bending edge 7a, 7b, between the bottom region 4 and the walls 2, 3 with their lower flange 14b. With their top flange 14a they are attached to the water barrier device 11, preferably welded. In this way forms the water barrier 11 and the stiffening beams 13a, 13b a triangular support, on the one hand stiffens the walls 2, 3 and the bottom portion 4 and on the other hand ensures a firm and secure position arrangement of the water blocking device 11.
