Abstract

The invention discloses a prefabricated integral resin concrete expansion device which comprises a first unit, a second unit and a waterproof adhesive strip. The first unit and the second unit have the same structure; the first unit comprises expansion joint profile steel and a resin concrete base, two layers of anchoring ribs with preset included angles are welded to the expansion joint profile steel, and the expansion joint profile steel and the two layers of anchoring ribs are prefabricated on the resin concrete base; the expansion joint profile steel on the first unit and expansion joint profile steel on the second unit are connected through the waterproof adhesive strip. The prefabricated integral resin concrete expansion device is exquisite in structure, small in buried depth and small in structural size, installation notches are shallow, it is not needed to prearrange embedded parts on a girder body or reserve installation notches in the girder body, installation can be realizedon a surface pavement layer of a bridge, the girder body structure is not damaged, the integrated design is not influenced, and the prefabricated integral resin concrete expansion device is especially suitable for thin-walled girder bodies.

Description

technical field [0001] The invention belongs to the technical field of highway bridges, and in particular relates to a prefabricated integral resin concrete expansion device and a construction method thereof. Background technique [0002] The expansion device of the highway bridge is the component installed in the last process of the bridge construction, which directly bears the repeated load of the vehicle wheel, especially when the bridge deck is uneven, it will be subject to a great impact. At the same time, because of its long-term exposure to the atmosphere, the use environment is relatively harsh, and the durability is poor, so the highway bridge expansion device is the most vulnerable and difficult to repair component in the bridge structure. Due to the performance problems of the materials used, the unreasonable structure, the lax construction quality control and the low precision of the installation process, the expansion joint device generally fails early.
