The frame prefabricated spatial with joints on screw couplings
Abstract
The general characteristics of the structural system of a fully assembled frame made of “H”elements are described. The “H” element is a frame of two racks, each one floor high, connected monolithically with a crossbar. Structural cells with a longitudinal, transverse or cross arrangement of bearing frames are assembled from these elements. The joints of the racks with crossbars are rigid and are located in the middle of the floor height. The overall spatial stability of the frame is provided by the arrangement of frame elements, as well as the use of various kinds of connections. Floor slabs are prefabricated. The joints of the frame racks are prefabricated-monolithic with the use of combined couplings. Connections of “H” elements on screeds with the use of strands made of smooth reinforcement or screw reinforcement rolled products.
