Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a comb-plate type telescopic device that is easy to install. Background Technology

[0002] Bridge expansion joints are joints installed at the hinge points between two beams or between a beam and an abutment to prevent bridge deck deformation. While bridge expansion joints solve the problem of bridge deck deformation, they leave gaps on the bridge deck, affecting vehicle traffic. To avoid affecting vehicle traffic, comb-tooth plate expansion devices are installed at the locations connecting the gaps between two beams or between a beam and an abutment.

[0003] Existing telescopic comb plates are installed between two bridge decks using a large number of bolts. The installation process of rotating multiple bolts is too cumbersome, making the installation of the comb plate telescopic device inconvenient and requiring a certain amount of time and effort to operate. Therefore, a comb plate telescopic device that is easy to install is proposed. Utility Model Content

[0011] Beneficial effects

[0012] This utility model provides a comb-plate type telescopic device that is easy to install. Compared with the prior art, it has the following advantages:

[0013] (1) This utility model rotates two threaded rods, which drive the gear to rotate. The gear drives the two toothed plates to move towards the middle. The two toothed plates drive the two rectangular plates to move towards the middle and insert into the rectangular hole through the moving plate.

It is more convenient to operate and saves installation time and effort.

[0014] (2) By rotating the threaded rod, the threaded rod will drive the fixing plate and the reinforcing plate to move downward through the threaded sleeve. The reinforcing plate will be inserted into the reinforcing groove, so that the reinforcing plate will limit the support plate and the comb plate again through the splicing plate, which can effectively improve the sturdiness of the comb plate installation.

A movable plate 11 is fixedly connected to the opposite side of the two toothed plates 10. A rectangular plate 12 adapted to the rectangular hole 6 is fixedly connected to the opposite side of the two movable plates 11.

[0023] It should be noted that the sliding can be stopped by moving the splicing plate 5 on the comb plate 4 to contact the tooth plate 10. At this time, the rectangular hole 6 and the rectangular plate 12, the reinforcing groove 18 and the reinforcing plate 17 are aligned.
