Abstract

The invention relates to a basalt fiber comb plate as well as a telescopic component and a telescopic device using the comb plate. The comb plate comprises a comb plate body; the front end of the combplate body is provided with a guide structure used for being in guide moving fit with the front guide rail in the left-right direction. The rear end of the comb plate body is provided with a front comb plate telescopic section used for extending into the position between two corresponding adjacent rear comb plates, a front comb plate step groove is formed in the top of the front comb plate telescopic section, and the top of the front end of the comb plate body is turned leftwards or rightwards to form a front comb plate gap blocking edge used for blocking the upper side of the corresponding rear comb plate step groove. The technical problem that in the prior art, impurities easily fall into the rear side of the front comb plate and the front side of the rear comb plate, and consequently blocking is caused is solved.

Description

technical field [0001] The invention relates to a basalt fiber comb board in the field of bridge construction, a telescopic member and a telescopic device using the comb board. Background technique [0002] In the process of road construction, bridges are the main means of crossing obstacles such as rivers, deep valleys, and roads. Due to thermal expansion and contraction caused by temperature changes, the bridge deck will produce longitudinal expansion and contraction deformation. Freely deformable telescopic devices are installed between the platforms to ensure the smoothness of the bridge deck and protect the structure. [0003] Existing telescopic devices such as "a kind of comb-type telescopic device and telescopic member" disclosed in Chinese patent CN110241719A, the comb-type telescopic device, that is, the comb-type telescopic device includes a front telescopic member and a rear telescopic member, and the front telescopic member includes a length along the The front...
