Bridge assembly type expansion joint device construction method

Abstract

The invention relates to a bridge assembly type expansion joint device construction method which comprises the following steps that 1, a temporary supporting piece is built between the ends, close to each other, of two adjacent beam bodies used for building a bridge, wherein the temporary supporting piece comprises a supporting plate and two baffles arranged on the two opposite side walls of the supporting plate correspondingly; the two ends of the supporting plate extend to one ends of the two adjacent beam bodies correspondingly, the baffle is vertically arranged, the lower end of the baffle abuts against the upper surfaces of the beam bodies, and the supporting plate is provided with a positioning piece used for limiting the supporting plate from disengaging from the beam bodies; 2, concrete is poured on the upper surface of the beam body to form a concrete bridge floor, and a reserved groove used for installing an expansion joint device is formed in the beam body area corresponding to the supporting plate; and 3, after the concrete is solidified and cured, when the expansion joint device needs to be installed, positioning of the supporting plate by the positioning piece is canceled, the supporting plate is taken down, the reserved groove is cleaned, and then the expansion joint device is installed in the reserved groove. The method has the effect of improving the negative effect caused by grooving in the prior art.

Description

technical field [0001] The present application relates to the field of expansion joint devices, in particular to a construction method for bridge-assembled expansion joint devices. Background technique [0002] At present, on large bridges, multiple expansion joint devices are generally installed to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge building materials, so as to reduce the probability of safety accidents [0003] The construction process of the expansion joint device in the related art is as follows: 1. Groove in the gap reserved between two adjacent beam bodies, and deal with the sundries in the groove and the gap; 2. Straighten out the reserved steel bars in the groove; Install the expansion joint device in the groove, and weld the reserved steel bars on the expansion joint device and the reserved steel bars in the groove firmly; 4. Pour concrete in the area where the steel bars in the groove and the reserve...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that in the related technologies, in order to ensure the stable installation of the expansion joint device, the expansion joints are generally treated after the bridge deck concrete is paved and hardened. At that time, since the pavement has been laid, it is necessary to use a cutting machine to cut grooves on the concrete bridge deck. On the one hand, dust will pollute the environment, and on the other hand, the cut concrete needs to be processed, which is time-consuming and laborious.
