FIELD: construction.
SUBSTANCE: invention relates to the field of construction and may be used in erection of light cast in place and precast slabs of low-rise buildings and structures. The slab comprises perforated support beams made of C-shaped or Σ-shaped profile, and a solid concrete filling between them. Perforation is made in the form of extended holes, the large axis of which is located on one line stretching along the wall of the support beam. According to the first version, on upper bends of the profile there are slots for concrete filling, and according to the second version of the upper part between the wall, the shelf and the bend there is a wooden bar. There are methods proposed to erect slabs and a forming element.
EFFECT: technical result consists in reduced material intensity of a structure and reduced time for assembly and disassembly of forms.
