Tendon fixing system of long span fire resistance deck strained at deck end and construction method of the same

摘要

The present invention can prevent deformation in the long span by giving a bending displacement amount upward without damaging or damaging the deck plate at the end of the deck, The present invention provides a tension-fixing system for a long-span refractory deck which is tension-fused in a trench and a method of construction thereof.The tension member fixing system of a long span refractory deck subjected to tension fixation at a deck end according to a preferred embodiment of the present invention is a tension member fixing system for controlling deflection of a deck plate main body supported by H beams opposing each other with a tension member, A supporter for a tension member which is joined to two places of the concrete filling cores which are opened upward of the deck plate main body; A tail fin reinforcing angle joined to both side end side edges of the deck plate body; And a tension member fixing hole joined to the rear edge reinforcing angle in a direction perpendicular to an arrangement direction of the deck plate main body; The opposite ends of the tensile material are inserted into the respective tensile member fitting grooves of the supporter for supporting the tensile material installed at two places, and then the upwardly bending force is generated in the deck plate body by tensing the tensile material.
