Embodiment Construction

[0020] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] to combine Figure 1-3 As shown, the telescopic unit components of the bridge include a movable plate 1 and a fixed plate 2, one end of the movable plate is a comb end 3, and the fixed plate 1 and the movable plate 2 are connected through a comb structure. The comb-tooth structure spans the gap at the end of the beam as a whole, so that the structure is reasonably stressed and durable. The ends of the comb teeth form a slope shape, and the garbage between the comb teeth is forcibly pushed ou...

Abstract

The invention discloses a bridge telescopic unit member and a bridge telescopic device. The bridge telescopic unit member can rotate horizontally and vertically and swing via deformation of a displacement column main body, thereby sufficiently meeting the displacement of the upper structure of a bridge under the action of external force and simultaneously meeting the damping requirement. Meanwhile, the use of center bolts is reduced, the overall strength of the displacement column main body is improved, and the situations of cracking and the like are reduced; the bridge telescopic device composed of the bridge telescopic unit member is independent in assembly function, long in service life, better in operating stability and beneficial to monitoring the quality of the links of manufacturing, installation, replacement, detection and the like.

Description

technical field [0001] The invention relates to the technical field of arrangement, construction or connection of expansion joints, in particular to a bridge expansion unit component and a bridge expansion device. Background technique [0002] The expansion device is one of the important functional components of the bridge. By installing the expansion device between the beam end and the beam end of the bridge, and between the beam end and the abutment, it can effectively adjust the load caused by the vehicle, the environmental characteristics and the physical properties of the bridge building materials. The resulting structural displacements lead to bridge damage issues. The telescopic device should meet the following conditions: fully meet the displacement of the bridge superstructure under the action of external force; must be firm, reliable and durable; be able to resist mechanical wear and collision; ensure smooth and safe traffic; keep. [0003] In the prior art, the ...
