ABSTRACT:
The invention relates to an open type box-unit with multi-purpose application for the complex industrial construction of prefabricated houses, of buildings with different numbers of stories, and to molding apparatus for its production. The box-unit has a floor and roof structure with a spatially reinforced concrete framework consisting of two longitudinal frames and transverse frames; the cross bars of the longitudinal frames have a reinforced cross section asymmetrical to the cross section of the columns and an uninterrupted reinforcement in a closed shape. At modular distances in the cross bars of the longitudinal frames there are provided critical zones with cross sections doubled with regard to the cross bars and the columns of the end transverse frames. These critical zones are designed for the connection of the reinforcement of the cross bars and the columns of the middle frames having variable cross sections. The molding facility comprises lower forms split in sections along the transverse axis of which there are form members connected with a system of hydraulic units. On an inverted U-shaped plain girder there are horizontal forms sectional in a transverse direction with upper forms on a system of stabilized Nurnberg shears there are external and internal sectional vertical forms. The molding facility is equipped with grouting units.
