Problems solved by technology

[0005] The purpose of the present invention is to provide a bridge expansion joint filling and strengthening member, which solves the problem that the previous bridge expansion joint filling and strengthening structures in the prior art are all integrated structures, and only the partial surfaces in the expansion joints have better connection and Support, unable to reinforce the whole. The one-piece structure is composed of steel bars connected, but the steel bars also have a raised structure. When the upper shield plate falls, it is easy to puncture the tire and cause a safety accident.

Embodiment 1

[0031] refer to Figure 1-5 , a bridge expansion joint filling and reinforcing member, comprising two symmetrically arranged beam bodies 2 and an expansion joint 1 between the two beam bodies 2, the top position between the two beam bodies 2 has a top plate 4, the top plate 4 Both sides are connected with the two beam bodies 2 through the first connecting mechanism 3, and both sides of the bottom of the top plate 4 are connected with the second connecting mechanism 5 through the support portion 6;

[0032] The first connecting mechanism 3 includes a connecting plate 306 that is fixedly connected to one side of the beam body 2. Both sides of the bottom of the connecting plate 306 are rotatably connected with mounting plates through the lugs 304. Attach the bolt rods to the mounting plate. Both sides of the plug-in board 305 are fixedly connected with T-shaped plug-in rods 301, and both sides of the inner cavity of the movable top plate 401 are provided with T-shaped sockets that...

Embodiment 2

[0040] As a further improvement of the above technical solution, when the bridge encounters earthquakes and typhoons during use, in order to ensure the normal use of the bridge, the device is adjusted according to the method described in this embodiment.

[0041] The second connecting mechanism 5 includes two connecting rods 506, one end of the connecting rod 506 is slidably connected with the first slider 507, and the other end is fixedly connected with the connecting block 505; the support part 6 includes two vertically arranged vertical rods 601 and The support plate 603, the vertical rod 601 is slidably connected with a second slider, one end of the support plate 603 is hinged with the second slider, the support plate 603 on the same side is rotationally connected by a pin shaft, and the pin shaft is fixedly connected with the adjustment groove 604, the adjustment groove 604 is provided with two rollers 605, the two rollers 605 are connected by compression springs, the roll...

Abstract

The invention relates to the technical field of bridges, in particular to a bridge expansion joint filling and reinforcing member, which solves the problem in the prior art that the previous bridge expansion joint filling and reinforcing structures are all-in-one structures, and only part of the surface in the expansion joint has better performance. The connection and support cannot be used to reinforce the whole. The one-piece structure is composed of steel bars, but the steel bars also have raised structures. When the upper shielding plate falls, it is easy to puncture the tires and cause safety accidents. The utility model relates to a bridge expansion joint filling and reinforcing member. The top plate is inserted into the beam body through the connecting plate, the mounting plate is rotated through the lug seat to fit the side wall of the beam body, and the bolt is fixedly connected with the beam body, and then the connecting rod is connected through the connection. The block is connected with two beam bodies. When the two beam bodies squeeze each other to reduce the expansion joint space, the squeeze spring and the top plate slide in the beam body, absorb the buffer force, provide effective support and reinforcement, and prevent the top plate from falling off. , and easy to install and connect.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a bridge expansion joint filling and reinforcing member. Background technique [0002] Bridge expansion joints are usually set between two beam ends, between beam ends and abutments or at the hinged position of the bridge. The purpose of setting expansion joints is to adjust the gap between the superstructure caused by vehicle loads and changes in bridge building materials or temperature. Displacement and connection. The expansion joints should be able to expand and contract freely, be firm and reliable, and the vehicles should run smoothly without sudden jumps and noises; they should be able to prevent blockages; installation, inspection, maintenance, and removal of dirt should be simple and convenient. Where the expansion joints are set, the railings and the deck pavement must be disconnected. [0003] The Chinese patent with the application number CN201610367701.8 discloses ...
