SPACE TRUSS WITH PROVISIONAL CONCRETE FORM FOR CIVIL ENGINEERING WORK SUCH AS BRIDGE FLOOR

摘要

PROBLEM TO BE SOLVED: To simplify the assembling and disassembling works and removal work by omitting the preparation and arrangement of reinforcements of a haunched bridge floor to be carried out in the construction site.;SOLUTION: This space truss is constituted of three-dimensional welding reinforcements 1 formed by combining longitudinal reinforcements 11, transverse reinforcements 12, and web reinforcements 13 and a concrete slab 2 of reinforcements formed to have a specified size by placing concrete in the lower part of the three-dimensional welding reinforcements 1. The space truss has a structure in which the end of the three-dimensional welding reinforcements 1 stick out of the concrete slab 2 and protrusions 21 are formed by thickening the ends of the concrete slab 2.;COPYRIGHT: (C)2001,JPO
