Description

Technical Field

[0001] The utility model relates to the technical field of bridges, and specifically, to a quick-change water stop belt expansion device. Background Art

[0002] The expansion device is arranged between the beam ends or between the beam end and the abutment, and is an important part of the bridge structure. On the one hand, it can transmit vehicle loads to ensure smooth and stable driving; on the other hand, it can adapt to the longitudinal and transverse expansion and displacement of the bridge; on the other hand, it can prevent rainwater, mud, sand and gravel and garbage from polluting the beam body, pier and bearing.

[0003] Although it does not need to bear too much load, the vehicle driving will repeatedly impact and vibrate the expansion device, and the repeated vibration will cause changes in the structure or performance of the rubber material components; and the expansion device is exposed in the natural environment for a long time, and temperature, ultraviolet rays, rain and snow, etc. will accelerate the aging of the rubber material components. Therefore, the water stop belt in the expansion device is a vulnerable component with a high replacement frequency. There are some problems in the existing expansion devices:

[0004] (1) The problem that the water stop belt in the existing expansion device is easily squeezed and damaged by sharp objects such as stones;

[0005] (2) The problem that the water stop belt in the existing expansion device is exposed in the natural environment for a long time, and is accelerated in aging and damage due to adverse factors such as vibration, temperature, ultraviolet rays, rain and snow.

[0006] (3) The problem that it is difficult to replace the water stop belt in the existing expansion device and the working efficiency is low. Content of the Utility Model

[0007] In view of the problems in the related art, the utility model provides a quick-change water stop belt expansion device to overcome the above technical problems existing in the existing related art.

[0008] For this purpose, the specific technical solution adopted by the utility model is as follows:

[0009] A quick-change water stop belt expansion device includes a plurality of first embedded steel bars. A fixing component is arranged on the first embedded steel bars, and an expansion component is arranged inside the fixing component. The fixing component includes a plurality of first special-shaped steels, the first special-shaped steels are arranged at one end of the first embedded steel bars, and special-shaped grooves are formed in the first special-shaped steels.

[0010] Further, in order to better ensure the expansion effect of the water stop belt, the expansion component includes a water stop belt, the water stop belt is arranged in the special-shaped groove, and rubber protrusions are arranged on both sides of the water stop belt.

[0011] Further, the rubber protrusions are adapted to the special-shaped grooves.

[0012] Furthermore, the waterstop is composed of a rubber sandwich layer and a stiffening plate. The rubber sandwich layer is provided in the middle of the waterstop, and the stiffening plate is arranged inside the rubber sandwich layer.

[0013] Furthermore, in order to better ensure the fixing effect of the telescopic assembly, a plurality of adsorption ports are opened in the special-shaped groove. One end of the adsorption port is provided with a conveying channel, and the conveying channel is opened inside the first special-shaped steel. The adsorption port is communicated with the conveying channel.

[0014] Furthermore, in order to better ensure the fixing effect, a treatment cavity is opened inside the first special-shaped steel, and the conveying channel is communicated with the treatment cavity. The treatment cavity is connected with an air extraction one-way valve and a pressure relief one-way valve.

[0015] Furthermore, in order to better facilitate quick replacement, the air extraction one-way valve and the pressure relief one-way valve are communicated with the treatment cavity.

[0016] The beneficial effects of the present utility model are as follows: By setting the telescopic assembly, a stiffening plate can be arranged in the waterstop, solving the problem that the waterstop is squeezed and damaged by sharp objects such as stones. In the structure where the stiffening plate on the waterstop is coated with rubber, when the waterstop is damaged and aged due to reasons such as repeated impact vibration, temperature, ultraviolet rays, rain and snow for a long time, the stiffening plate can also play a waterproof role, thereby increasing the service life of the telescopic device. By setting the fixing assembly, the installation and disassembly directions of the waterstop are set vertically, and there is sufficient operation space for installation and disassembly, greatly reducing the operation difficulty of replacing the waterstop, and multiple fixings can also be carried out, so as to better ensure the installation efficiency and disassembly efficiency of the waterstop.
