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

摘要

The present invention relates to a long span refractory deck which is capable of applying an upward bending displacement amount without damaging or damaging a deck plate, automatically adjusting the direction of placement of a tension member at a fixing point, And a method of constructing the same. The tension member fixing system of a long span refractory deck subjected to tension fixation in a beam according to a preferred embodiment of the present invention is a tension member fixing system for controlling deflection of a deck plate body supported by mutually opposing H- A pair of reinforcing bars supported on the deck plate body by two bolts and opposed to each other at two places of the concrete filling cores which are opened upwardly of the deck plate main body; a steel bar connecting latches respectively connected to the pair of steel bar supporting plates; Wherein the steel rods for tensioning of the tension members, both ends of which are sandwiched between them, are constituted by upward point elements of the deck plate; And a tension member fixing bracket for fixing the tension member to the upper flange of the H-shaped beam so that the upper flange is self-directionally aligned along the arrangement direction of the tension member; Wherein the tension member is installed such that both ends of the tension member are connected to the tension member fixing bracket side and at the same time are brought into contact with the lower surface of the tension member point steel bar provided at two places in the remaining section so that the upward supporting force is exerted.
