Prefabricated block for bridge expansion joint and using method thereof

Abstract

The invention discloses a prefabricated block for a bridge expansion joint and a using method thereof. The prefabricated block comprises a steel plate, lifting hooks, a prefabricated slab, a frameworkand a socket, wherein the lifting hooks are symmetrically arranged on the two sides of the prefabricated slab, the steel plate is fixedly connected with the framework, the lifting hooks rare fixedlyconnected with the framework, the socket is located in the middle of the cross section of the prefabricated slab, one ends of the lifting hooks penetrate through the positions near the upper parts ofthe side surfaces of the prefabricated slab, and the other ends of the lifting hooks penetrate through the positions near the lower parts of the side surfaces of the prefabricated slabs, the lifting hooks are of inclined structures on the side surface of the prefabricated slab, and the lower surface of the steel plate coincides with the upper surface of the prefabricated slab. The prefabricated block can be reused, the working efficiency is high, waste materials are prevented from blocking the expansion joint, the construction environment is protected, the flatness of the expansion joint afteruse is high, and the phenomenon that the vehicle jumps when the vehicle passes through the expansion joint is avoided, and due to the fact that the rigid processing mode of the prefabricated block isadopted at the expansion joint, the expansion joint can have a good flatness and initial compaction degree when a paver passes through the expansion joint.

Description

technical field [0001] The invention relates to an auxiliary device for bridge deck construction, in particular to a prefabricated block used for bridge expansion joints. Background technique [0002] In the construction of bridge expansion joints, the construction method of reverse slotting is generally adopted. Before construction, the expansion joints must be treated before the asphalt surface structure can be paved on the bridge. During the actual construction, the treatment of bridge expansion joints is mostly too random, so that the expansion joints are covered with road waste materials, which makes the expansion joints lose part of their use functions; some use sand filling to facilitate the construction of asphalt from the bridge deck, resulting in The flatness is not ideal, resulting in the phenomenon of jumping from time to time. Contents of the invention [0003] The purpose of the present invention is to develop a prefabricated block for bridge expansion joint...
