Lock Metal Wall Expansion Joint

To ensure the normal operation of the expansion joint cover device and prolong its service life, the maintenance and maintenance of the normal expansion joint cover is an indispensable important link. Therefore, the maintenance work of the expansion joint cover should be as follows:

1. Combined with the daily maintenance work of the building, often clean the backlog of sand, stone chips and other debris in the sealing rubber belt to prevent the expansion joint cover device from affecting the freedom of expansion and contraction when the expansion joint cover device is stressed, and the sealing rubber belt is pierced by large stones. Once water leakage is discovered, the tape should be replaced in time.

2. Frequently check whether the joints of the wall paving on both sides are damaged or cracked, causing leakage. Once discovered, it should be repaired in time to avoid affecting the anchoring strength between the deformation joint device and the beam and slab.

3. Always check whether the top surface of the expansion joint cover device is flat. If abnormal unevenness occurs, further check whether the sliding pressure bearing or sliding pressure bearing is damaged, and if it is damaged, it should be replaced in time. The design has fully considered the convenience of parts replacement, and passed actual tests, which is completely feasible.

4. In the daily maintenance, if excessive uneven displacement is found between the joints of the expansion joint cover device, you can check whether the components of the displacement control system are damaged in time. If any parts are found to be damaged, they should be replaced in time. It is a standard component, easy to replace. However, in general, the strength and durability of the displacement control system have been fully considered in the design, and this phenomenon is not easy to occur.

5. The expansion joint cover device is a steel structure. Although it has been treated with better protection before leaving the factory, it is normal for corrosion after a period of use due to the influence of the environment. At this time, the maintenance part should be re-anti-rust treatment on schedule. , To ensure the durability of the expansion joint cover device.
