Reinforced bridge expansion joint structure

Abstract

The invention relates to a reinforced bridge expansion joint structure which comprises a bottom rack, a fine adjustment mechanism, a bearing frame, a height adjustment mechanism and a clamping and locking mechanism, and can solve the following problems that a, a traditional bridge expansion joint can only aim at a bridge floor structure with one thickness in the using process, and when bridge floors with different thicknesses need to be used, expansion joint structures of different specifications need to be produced, the consumed time is long, and the production cost is high, and b, the gap distance in a traditional bridge expansion joint structure is fixed, the expansion and contraction degrees of concrete in a bridge are different according to factors of different regions, different climates and the like, so that the widths of the bridge expansion joints are different, meanwhile, when the bridge expansion joint structure is in direct contact with concrete, due to the fact that the contact area is small, the attachment degree of the concrete on the surface of the bridge expansion joint structure is unstable, falling is easily caused, the action effect of the bridge expansion joint structure is poor, and use of a bridge is affected.

Description

technical field [0001] The invention relates to the field of reinforced bridge expansion joints, in particular to a reinforced bridge expansion joint structure. Background technique [0002] Reinforced bridge expansion joints are a kind of deformable structure that meets the deformation requirements of the bridge deck. It is usually set between the ends of the two girders, and at the hinged position between the two ends and the bridge abutment or bridge. The reinforced bridge expansion joints can be adjusted by vehicles. The displacement and connection between the concrete structures caused by the load and bridge building materials can also prevent the bridge deck concrete from causing cracks in the bridge deck structure due to climate temperature changes, which will cause the bridge deck structure to break and affect the driving speed and safety. , Seriously, it will cause driving safety accidents. [0003] At present, the following problems exist in the use of reinforced ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a reinforced bridge expansion joint structure, which can solve the following problems in the use of reinforced bridge expansion joints: a. The traditional bridge expansion joints can only be used for bridge deck structures of one thickness, When it is necessary to target bridge decks of different thicknesses, expansion joint structures of different specifications are required, and the production of expansion joint structures of different specifications takes a long time, a large workload and high production costs. b The internal gap distance of the traditional bridge expansion joint structure is Certainly, according to different regions, different climates and other factors, the degree of thermal expansion and contraction of the concrete inside the bridge is also different, so the width of the bridge expansion joints is also different. At the same time, when the bridge expansion joint structure is in direct contact with the concrete, due to the small contact area , the adhesion of concrete on the surface of the bridge expansion joint structure is unstable, and it is easy to cause falling off, resulting in poor effect of the bridge expansion joint structure and affecting the use of the bridge
