EXECUTION METHOD OF JOINT SECTION IN BRIDGE-SURFACE PAVEMENT OF HIGHWAY BRIDGE, ETC.

摘要

PROBLEM TO BE SOLVED: To facilitate the removal operation of a joint filler, and to improve the efficiency of the execution of works by forming a joint filler in the laminated board of a resin foam and a rigid heat-insulating board in a method of construction, in which the joint filler is removed after the construction of a paving body and an injecting joint filler is filled. ;SOLUTION: A required joint filler 7 is disposed beforehand along the curb concrete or wheel guard concrete 2 of a highway bridge, etc. A required paving body 10 is constructed and the joint filler 7 is removed, and a removed space section is filled with an infecting joint filler and the infecting joint filler is finished. In the execution method of the Joint section of the bridge-surface pavement, the joint filler 7 is formed in a laminated board consisting of a resin foam 8 and a rigid heat-insulating board 9. When the joint filler 7 is arranged, the surface of the resin foam 8 is faced oppositely to a concrete 2 surface, and the surface of the heat-insulating board 9 is faced oppositely to the side face of the paving body 10. When the joint filler 7 is removed, the resin foam 8 is dissolved and treated or incinerated and treated by solvent spray or a gas burner and a space section is formed. Accordingly, the residual rigid heat- insulating board 9 can be extracted easily.;COPYRIGHT: (C)1997,JPO
