Sidewalk precast slab of fully-assembled bridge and construction method of sidewalk precast slab

Abstract

The invention relates to the technical field of sidewalk construction of bridge in civil engineering. The invention discloses a sidewalk precast slab of a fully-assembled bridge and a construction method thereof. The sidewalk precast slab comprises a rectangular plate-shaped precast slab main body made of steel bars and concrete, an inserting protruding block is arranged on the first side face, inthe width direction, of the precast slab body, an inserting notch matched with the inserting protruding block in shape is formed in the second side face, away from the first side face, of the precastslab body in the width direction, and the inserting notch is used for being connected with the inserting protruding block on the adjacent precast slab body in a clamped mode. A lap joint cantilever is arranged on the third side face, in the length direction, of the precast slab body. A lap joint bearing arm is arranged on the fourth side face, away from the third side face, of the precast slab body in the length direction, the lap joint cantilever and the lap joint bearing arm are symmetrically arranged with the center of the precast slab body as the center, and the lap joint bearing arm is used for being connected with the lap joint cantilever on the adjacent precast slab body in an embedded mode. The precast slab and the construction method have the effects of convenience in manufacturing, quickness in mounting, good construction quality and the like.

Description

technical field [0001] The invention relates to the technical field of bridge sidewalk construction in civil engineering, in particular to a sidewalk prefabricated slab for a fully assembled bridge and a construction method thereof. Background technique [0002] At present, the sidewalk prefabricated slabs of existing bridges are mainly used for non-motorized vehicles, and the sidewalk prefabricated slabs present a rectangular plate-like structure. figure 1 As shown, the layout of the sidewalk after laying the sidewalk prefabricated panels is as follows figure 2 shown. [0003] The manufacture of sidewalks in the prior art is mainly completed by prefabrication. Since the prefabricated panels of sidewalks are relatively simple rectangular plates, they can be prefabricated rapidly during the prefabrication process. However, due to the simple rectangular plate shape, when the sidewalk prefabricated panels are installed, the lack of fixing devices between the sidewalk prefabr...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sidewalk prefabricated board of a fully assembled bridge and its construction method in view of the defects in the shape, installation and use of the rectangular plate-shaped sidewalk prefabricated board in the prior art, which has the advantages of convenient manufacture, installation Fast, good construction quality and other effects, it solves the problems existing in the prior art such as weak bonding between sidewalk prefabricated panels and sidewalk prefabricated panels, joint cracking and water seepage, etc.
