イストスラブ版。[Claims for Utility Model Registration] (1) Single T-shaped or double T-shaped small beams in the floor cross section, and rib-shaped forming of said small beams within a plate formwork in which each molded part of the lower half of the slab is connected. The prefabricated truss reinforcing bars, which have been curved in an arc shape, are placed vertically in the section, and the truss reinforcing bars are rolled down until they become horizontal.
In this state, concrete is poured up to the majority of the slab, and after the poured concrete has developed the required strength, the pressing force of the assembled truss reinforcing bars is released to introduce prestress. In the cast-jyoist slab version, the assembly truss reinforcing bars are attached to the upper chord member made of single or double reinforcing bars, and the lower chord member made of single reinforcing bars at each required position, and connecting hardware is attached at each required position.
This is a semi-precast cast joist slab version using prefabricated truss reinforcing bars, characterized in that diagonal members are connected between the same connection fittings of the upper and lower chord members. (2) The connecting fitting is constructed by bending a pair of cylindrical tubes with a broken circular cross section at both ends of the flat plate part, and each tube is fitted and clamped by the upper chord member, and the free end of the cylindrical tube is 2. The semi-precast cast joist slab plate according to claim 1, wherein an edge is welded to the flat plate part, and an end of the diagonal member is welded to the flat plate part. (3) The connecting fitting has a vertical plate extending from one end of the cylindrical tube with a cut-off circular cross section, and the cylindrical tube is fitted into and gripped by the lower chord member and the upper chord member, and the other end edge of the cylindrical tube is attached to the lower chord member and the upper chord member. 2. The semi-precast cast slab plate according to claim 1, wherein the diagonal member is welded to a vertical plate, and an end portion of the diagonal member is welded to the vertical plate.
