    The building from the roof, walls, floors and other floors above all the components are disconnected.

    Because the foundation of the building is affected by the temperature change in the ground, it is not necessary to disconnect.

    Expansion joint width is generally 2 cm to 3 cm, and there are thermal insulation materials in joint.

    The distance between the two expansion joints is clearly defined in the specification of the building structure.


    III

    Q: What are the structural requirements of type steel expansion joint?

    A:

    1 - In the two directions of being parallel and being perpendicular to the axis of the bridge are free to flex.

    2 - Firm and reliable.

    3 - There is smooth and there has no sudden jump or noise when the vehicle is passing by.

    IV

    Q: What are the matters should be attention to about the type steel expansion joint?

    A: The following matters should be attention to:

    1 - If the position of the embedded steel bars on the beam plate is incorrect or there is no pre embedded reinforcement, you need to use the reinforced fill bar.

    2 - Clean and link the anchor after cutting.

    3 - The welding seam of reinforcing steel should be enough and the welding should be firm.

    4 - The surface elevation of concrete should be correct .

    5 - If you want the effective telescopic performance, you should ensure the anchor should be firm.

    6 - The curing time of concrete should be enough.

    Don't open the traffic because of the lack of maintenance time.
