METHOD FOR MANUFACTURING OF CAST IN PLACE AND PRECAST NODE OF PILLAR CONNECTION WITH CROSSBAR

摘要

FIELD: construction.SUBSTANCE: each crossbar is concreted with support cantilevers, in a groove is made in the pillar. Connecting elements of the crossbar are made in the form of a steel rope with clamp couplings pressed at its ends. Concrete extraction is continued until the working reinforcement of the pillar is exposed. The crossbar comprises support cantilevers from a steel rolled shape with protrusion outside the limits of the crossbar end. Each of rope elements is preliminarily folded in two to form a loop protruding beyond the end of the crossbar. Ends of rope elements are solidified in the body of the crossbar. Then crossbars are installed into the design position relative to the pillar. Afterwards in the pillar recess they bend the loops of ropes, which are inserted between the working reinforcement of the pillar, and then spread into the design position. Additional reinforcement rods are placed inside the loops of the ropes. Afterwards the formwork and the node of connection are installed in the volume of the recess and filled with concrete.EFFECT: lower labour intensiveness of assembly, increased operational capabilities and reliability.9 dwg
