Construction methods and buried joint structure and buried joint construction bracket assembly of buried joint structure

摘要

PROBLEM TO BE SOLVED: To realize a cut-off function in a relatively small girder joint gap part at a low cost.;SOLUTION: In a concrete parapet (breast wall) 110 and a concrete slab 120 positioned freely movably across a girder joint gap part G, concrete on an upper surface near the girder joint gap part G is removed to form a parapet (breast wall) construction hole 111 and a slab construction hole 121, a metal fitting assembly 10 which comprises a frame plate 11, a frame plate 12, a trapezoidal buffer material 32, anchor attaching ribs 13 and height adjusting structures 14 or the like, is inclined and face each other across the girder joint gap part G is arranged, is buried by placing site placed concretes 113, 123, and is then covered with a bituminous sheet 140, an asphalt pavement leveling layer and an asphalt pavement surface layer. Further, a secondary cut-off structure 30 for sealing by filling a seal material from a cloth bag 31 with a rubber sheet into a triangular space between the frame plate 11 and the frame plate 12 is constructed and a buried joint structure 100 is obtained.;COPYRIGHT: (C)2013,JPO&INPIT
