Description

Maintenance-free water-stopping sealing rubber belt

Technical Field

The utility model belongs to the technical field of bridge expansion joints, and particularly relates to a maintenance-free water-stopping sealing rubber belt.

Background

The water-stop sealing rubber belt for the bridge expansion device adopted in the market at present is V-shaped, and is shown in figure 1: two spherical bulges at the upper end of the V shape are clamped in the deformed steel groove, and the bridge beam plate drives the change of the gap width of the expansion device through expansion with heat and contraction with cold. As shown in fig. 2: in order to prevent rainwater from flowing directly from the telescoping device to the bottom of the bridge, the two ends of the telescoping device are usually tilted in conventional designs. The sealing rubber belt of the water stop of the conventional modulus type expansion device is assembled with the section steel like a long pocket, the water stop effect can be completely achieved, rainwater, sewage and the like can be effectively prevented from flowing into the beam bottom from the expansion device and corroding beam bottom components. But also because of the special shape of the water-stopping sealing rubber belt structure for the modular expansion device, the road garbage is very easy to store in the expansion joint of the expansion device. The expansion joint position of the bridge expansion joint device in normal use needs to be regularly closed to check and clean rubbish in the joint, so that the use performance of the expansion joint device cannot be influenced. The rubbish in the seam of the telescopic device needs to be cleaned by a professional person for closing the way, which wastes time and labor and influences the traffic, so that regular inspection and cleaning are difficult to achieve. When the expansion joint of the expansion device is larger due to weather reasons, the tire of the running vehicle is easier to be provided with larger hard objects like a screw rod and a nut. Sundries such as iron blocks fall into the gaps of the telescopic device. Road garbage in the gap is more and more compact under the rolling of the tires of passing vehicles. When the weather changes the temperature and risees, the gap of telescoping device diminishes, and closely knit road rubbish in the gap is not in time cleared up, and thrust can directly transmit the deformed steel that the expansion joint was used between roof beam and roof beam on, can produce two kinds of consequences, 1. Deformed steel can be deformed and is broken weld even drops with the anchor muscle because the anchor part of telescoping device is all in the concrete, and the maintenance can't be at all, can only change, if change untimely, can cause very big potential safety hazard for passing the vehicle. 2 because the expansion joint of the expansion device is filled with compact road garbage, the expansion function is lost, and the phenomena of jacking of the main beam or cracking of the abutment back wall can be caused.

In conclusion, the traditional V-shaped water-stopping sealing rubber belt for the bridge expansion device is easy to store garbage, easy to damage and short in service life. 2. Have their own application drawbacks, but are not changed. The problem that exposes in its use leads to the national transportation department to need to invest in a large amount of manpower, material resources and fund to change the telescoping device every year, causes the waste on a large amount of funds for the relevant department of country.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a maintenance-free water-stopping sealing rubber belt which comprises a rubber belt body, wherein the rubber belt body is symmetrically arranged, two fixed ends are arranged on the outermost side of the rubber belt body, a working part is arranged in the middle of the rubber belt body, and the fixed ends and the working part are integrally formed.

Further, the fixing end is provided in an ear shape.

Furthermore, be connected with the deformed steel on the stiff end, the stiff end joint is in the recess in the deformed steel.

Further, the working part is of a hollow rectangular structure and is divided into an upper layer and a lower layer.

Compared with the prior art, the utility model has the following beneficial effects:

1. after the water-stopping sealing rubber belt is used for the telescopic device, garbage on a road is not easy to enter a telescopic gap of the telescopic device, and even if the garbage enters the telescopic device, the garbage can be automatically cleaned out due to the elastic property of rubber, the gap of the telescopic device can be basically free from regular cleaning and maintenance, and the telescopic function of the telescopic device can be always ensured.

2. The utility model has the function of automatically cleaning road garbage, so that the problems of profile steel deformation, anchoring rib open welding, profile steel falling and the like caused by thermal expansion when the gaps of the telescopic device are filled with the road garbage like a conventional telescopic device are solved, and the service life of the telescopic device can be prolonged exponentially.

3. The utility model adopts a rectangular structure and is divided into an upper layer and a lower layer, even if the first layer is damaged, the second layer can also play a role of water stopping, and the structure of the utility model is equivalent to that of two water stopping adhesive tapes for conventional expansion devices, so the service life of the utility model is also doubled and surpassed that of a sealing water stopping belt for the conventional expansion devices.
