Abstract

The invention relates to the technical field of bridge accessories, in particular to a dual-waterproof replaceable telescopic device. A telescopic section is arranged in the middle of an upper W-shaped rubber strip, and the upper W-shaped rubber strip can perform heat expansion and cold contraction together with a beam body without being damaged by the beam body through the structure of the telescopic section; pressing blocks for fixing are symmetrically arranged on the two sides of the upper W-shaped rubber strips, and therefore the stability of the upper W-shaped rubber strip is improved, and replacement is convenient; the dual-waterproof effect of the telescopic device is realized through the upper W-shaped rubber strip and a lower U-shaped rubber strip, the waterproof performance is improved; and by means of the upper W-shaped rubber strip and the lower U-shaped rubber strip made of an elastic material, the telescopic device can be suitable for structures with irregular shaped sections, and a positioning assembly is convenient to replace.

Description

technical field [0001] The invention relates to the technical field of rail transit bridge accessories, in particular to a double waterproof replaceable telescopic device. Background technique [0002] At present, in the laying process of track bridges, there is usually a certain gap between the beam body and the beam body. The cross-sectional shape of the gap may be a nonlinear structure. For the deformation space generated by the thermal expansion and contraction of the beam body, However, if this gap is not treated, rainwater will fall along the bridge gap in rainy and snowy weather, thereby affecting the underlying foundation, thereby reducing the service life of the bridge structure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double waterproof replaceable telescopic device for the above-mentioned technical deficiencies. The telescopic section is arranged in the center of the upper W-shaped rubber stri...
