The invention relates to the construction, in particular to processes for installation of cast-in-situ floor with prestressed reinforcement, and can be used during the installation of cast-in-situ floors of buildings and structures.In the process for installation of cast-in-situ floor with prestressed reinforcement is carried out erection of vertical load-bearing structures of the building, is installed the floor formwork, is placed therein nonprestressed and prestressed reinforcement. The prestressed reinforcement is laid in the form of solid pieces along the full length and/or width of the building. On the perimeter of the building, from the outside, to the vertical load-bearing structures is carried out fastening of vertical struts/frames, is carried out tension of prestressed reinforcement with the transfer of force from it to the struts/frames, is concreted the floor and, upon concrete reaching the stripping strength, is carried out stripping of the floor with the transfer of tensile force to the concrete. |
