Description

 Bridge joint foreign matter prevention device {PROTECT CONTAMINATION OF THE BRIDGE JOINT}

The present invention is to provide a device for preventing the introduction of foreign matter in the bridge joint

 To apply to bridge joints.

Not applicable

   In the existing bridge type joints, foreign materials are introduced into the gaps between the joints,

   Recruitment device is full of debris, shortening the life of joint, and frequent maintenance

   It is expensive to repair and the road environment gets worse due to the introduction of foreign substances in the joint.

   The present invention is intended to avoid introducing foreign matter into the joint.

  Knowing the problems of bridge joints while driving a vehicle for many years,

  When overseas bridge joint technology is applied in Korea while checking the installation case of joint

  The problem caused by the introduction of foreign matter into the bridge joint has not been solved.

  In order to solve this problem, the invention was invented through various methods.

This design is an attempt to be applied for the first time in Korea.

In the future, various foreign matters will be connected to all bridge type joints, both domestic and overseas.

Since it is not drawn in, it is possible to apply this equipment to foreign countries

The opportunity is to make back export opportunities.

-Clean the environment of the bridge joint

-Extend the life of bridge joints

-Reduce noise when driving

-It can be applied to repair as well as new installation.

-Easy to construct

-It can also contribute to the prevention of vehicle safety accidents caused by foreign objects in bridge type joints.

Various existing bridge types prior to application of this device to bridge joints

About the problems that occur in the actual application by making a model of the joint

Through several tests, the test was completed for durability and abrasion resistance.

As a result, the invention is invented.

   Next, the present invention will be described in detail with reference to FIG. 1.

     Bridge type joints are all bridges due to seasonal factors

     Contraction and extension are repeated.

     1 is a side view illustrating the connection portion of the bridge joint

     In the summer, the joint ① contracts.

     In winter, the device ① is extended to prevent foreign substances from entering.

     The device ③ reduces the impact on the device when the vehicle is driving.

     The device ④ is to make the slide function of ① easy.

     The device ② is to support the device ①.

     It is possible to install and install the equipment separately and connect the equipment for installation.

      And since it can be assembled, it can be modified according to the bridge type joint shape.

Claims (2)

    Device is used between the bridge joints to prevent foreign substances from entering.     It is also applicable to overseas bridge joints.
