Abstract

The invention provides an integrated integral installation comb plate expansion joint device and a construction method. The expansion joint device is long in service life and high in on-site installing operation efficiency and achieves comfort driving. The integrated integral installation comb plate expansion joint device is installed on notches of beam bodies at the two sides and used for connecting the beam bodies at the two sides. The integrated integral installation comb plate expansion joint device comprises a comb plate, anchoring beams, a sliding plate and a water stop rubber belt; the comb plate comprises a movable end comb plate body and a fixed end comb plate body, a rotating hinged base is arranged below the movable end comb plate body, and the rotating hinged base and the movable end comb plate body are connected into a whole through movable end anchoring bolts and hinged to the corresponding anchoring beam; the sliding plate is arranged under the fixed end comb plate body and connected with the other anchoring beam through detachable bolts, and the fixed end comb plate body and the sliding plate are anchored to the beam bodies through fixed end anchoring bolts. The two ends of the water stop rubber belt are connected with the side walls of the two anchoring beams respectively.

Description

technical field [0001] The invention relates to the technical field of traffic engineering construction, in particular to an integrated installation comb plate expansion joint device and a construction method. Background technique [0002] The traditional comb-tooth plate expansion device is mainly composed of large and small fixed comb-tooth plates, anchor bolts and rubber waterstops. The large and small fixed comb-tooth plates are assembled on site and fixed directly on both sides of the expansion joint through anchor bolts. On the beam body, the installation accuracy is low; the anchor bolts are the main stress-bearing components. Under long-term loads, the anchor bolts are easy to loosen or fall off, which affects driving safety; It is not easy to pour densely, which affects the service life; the comb plate is in rigid contact with the beam body, which cannot adapt to the corner of the beam body under load, which affects driving safety. Contents of the invention [00...
