Embodiment Construction

[0020] Such as figure 1 As shown, the present invention provides a new pre-embedded unit type ultra-long life multi-directional displacement bridge telescopic device, including a main tooth plate and an auxiliary tooth plate, and the main tooth plate and the auxiliary tooth plate respectively include a tooth plate part 1 and a comb tooth part 7. The main tooth plate is installed on the first bridge girder body, and the auxiliary tooth plate is installed on the second bridge girder body. The comb tooth parts 7 of the main tooth plate and the auxiliary tooth plate cross each other and have gaps, and are located between the first bridge girder body and the second bridge girder body. Above the gap between the girder bodies of the second bridge.

[0021] A box body 2 is fixed on the lower surface of the tooth plate part 1, and the box body 2 includes a horizontal plate 21 and a vertical plate 22 which are sequentially connected into a closed square structure. Adjusting grooves, e...

Abstract

The invention relates to a novel pre-embedded unit type super-long-lifetime multidirectional displacement bridge expansion device. The device comprises a main toothed plate and an auxiliary toothed plate, wherein the main toothed plate and the auxiliary toothed plate respectively comprise a toothed plate part and a comb tooth part; a box body is fixed on the lower surface of the toothed plate part; the box body is filled with concrete; the box body comprises transverse plates and longitudinal plates which are sequentially connected to form a closed square structure, the transverse plates and the ;longitudinal plates outside each toothed plate part are provided with a plurality of adjusting grooves; a height adjusting plate is arranged in each adjusting groove and fixed to an embedded plate; shear nails are connected to the bottom of the embedded plate. The box body can be vertically adjusted relative to the height adjusting plates so that the height of the box body can be adjusted, and then the height of each toothed plate can be adjusted. The device has the advantages of fast installation, no need of slotting, no construction waste, immediate installation and immediate communication, material saving, time saving and labor saving.

Description

technical field [0001] The invention relates to the technical field of bridge expansion joints, in particular to a novel pre-embedded unit type ultra-long-life multi-directional displacement bridge expansion device. Background technique [0002] At present, the expansion joints produced in the same field have the following disadvantages: [0003] 1. Expansion joints cannot be pre-embedded in the beam body, and steel bars need to be removed and added during installation. The process is cumbersome, and it cannot be quickly leveled with the road surface. [0004] 2. The main tooth plate and the auxiliary tooth plate are installed separately, and the installation process is cumbersome. It is necessary to connect the main tooth plate and the auxiliary tooth plate on site, which prolongs the construction time on site. [0005] 3. The rubber waterstop of the expansion joint cannot be replaced. Contents of the invention [0006] The technical problem to be solved by the present ...
