Description

Technical Field

[0001] This utility model relates to the field of building expansion joint technology, specifically to an expansion joint device for preventing beams from falling off. Background Technology

[0002] Bridge expansion joints are installed to accommodate bridge deck deformation and are typically located between the ends of two beams, between a beam end and an abutment, or at hinged joints of the bridge. Bridge expansion joints can regulate displacement and connections between the superstructure caused by vehicle loads and bridge construction materials.

[0003] According to a public announcement of an anti-falling beam expansion joint device (Announcement No.: CN215366807U), the anti-falling beam expansion joint device of the present invention can limit the displacement of the bridge beam end during an earthquake, and the beam end will not separate at the expansion joint position, thereby preventing the beam end from falling and improving safety performance.

[0004] However, in actual use, the comb plates of the above-mentioned equipment are subjected to loads from vehicles, pedestrians, etc., and the comb plates are prone to breakage after long-term use, which affects the use of the comb plates; in view of this, we propose an anti-fall beam expansion joint device.

[0005] The purpose of this utility model is to provide an anti-fall beam expansion joint device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a beam-prevention expansion joint device, comprising a fixing plate, a positioning hole on the upper surface of the fixing plate, a support mechanism on the outer side of the fixing plate, and a promoting mechanism on the outer side of the fixing plate, the support mechanism comprising:

[0007] A toothed plate is fixedly installed on the side wall of a fixed plate, and a support block is installed on the side wall of the fixed plate. A groove is formed on the side wall of the fixed plate.

[0008] A reset spring, one end of which is fixedly connected to one end of a groove, and the other end of which is fixedly connected to a support plate. A semi-circular protrusion is fixedly installed on the upper surface of the support plate.

[0009] Preferably, the promoting mechanism includes a trapezoidal block, which is fixedly installed on the side wall of the fixed plate, and a round rod is fixedly connected to the inner wall of the trapezoidal block.

[0010] Preferably, the trapezoidal block has a circular hole on its side wall, and the circular rod passes through the surface of the trapezoidal block.

[0011] Preferably, the number of toothed plates is set to several, and the several toothed plates are fixedly installed on the side wall of the fixed plate in a linear array.

[0012] Preferably, the shape of the groove is adapted to the shape of the support plate, so that the support plate can slide inside the groove.

[0013] Preferably, the toothed plate, the support block, and the trapezoidal block are on the same vertical horizontal plane, so that the support block and the trapezoidal block can ensure the stable use of the toothed plate.

[0014] Preferably, there are two fixing plates, and the toothed plates on the two fixing plates are staggered and support each other, which further enhances the load-bearing capacity.

[0015] Compared with the prior art, this utility model provides an expansion joint device to prevent beams from falling off, which has the following beneficial effects:

[0016] 1. This anti-fall beam expansion joint device is equipped with a support mechanism. The toothed plate is supported by the support plate, and the return spring makes the support plate support the two fixed plates. Secondly, it supports the toothed plate. In response to the expansion and contraction deformation of buildings, bridges and other structures under the influence of temperature changes, loads and other factors, the support plate can compress the return spring to ensure that the width of the expansion joint can be adjusted accordingly. The semi-circular protrusion on the support plate facilitates the deformation between the two fixed plates, thereby ensuring the stable use of the toothed plate.

[0017] 2. This anti-fall beam expansion joint device is equipped with a promotion mechanism. The trapezoidal block is placed directly below the toothed plate, and together with the support plate, support block and trapezoidal block, it stably supports the toothed plate. The round rod connects multiple trapezoidal blocks to promote the stability of the overall structure and ensure the stable use of the toothed plate. Attached Figure Description

[0024] In one embodiment of this utility model, the toothed plate 301 is fixedly installed on the side wall of the fixing plate 1, the side wall of the fixing plate 1 is provided with a support block 306, the side wall of the fixing plate 1 is provided with a groove 302, one end of the return spring 303 is fixedly connected to one end of the groove 302, the other end of the return spring 303 is fixedly connected to the support plate 304, and a semi-circular protrusion 305 is fixedly installed on the upper surface of the support plate 304.

[0025] In addition, the promoting mechanism 4 includes a trapezoidal block 401, which is fixedly installed on the side wall of the fixing plate 1. A round rod 402 is fixedly connected to the inner wall of the trapezoidal block 401. A round hole is opened on the side wall of the trapezoidal block 401, and the round rod 402 passes through the surface of the trapezoidal block 401.

[0026] In this embodiment of the invention, a plurality of toothed plates 301 are provided, and the plurality of toothed plates 301 are fixedly installed on the side wall of the fixing plate 1 in a linear array. The shape of the groove 302 is adapted to the shape of the support plate 304, so that the support plate 304 can slide inside the groove 302. The toothed plates 301, the support block 306, and the trapezoidal block 401 are on the same vertical horizontal plane, thereby ensuring the stable use of the toothed plates 301.
