When the telescopic seam in place to install with the crane lifting, should check the crane hook, prevent decoupling, lifting should be strictly in accordance with the manufacturers for crane hoisting, and in accordance with the design drawings to rolled steel. In the fixed process using the method of controlling the cable telescopic device in line and straight, with the length is more than 3m or Aluminum Alloy steel I-beam has enough rigidity are laid on the joints on both sides. To control the elevation along the vertical direction of steel joints with 1m spacing and placed on both sides of the joint construction with wedge type steel joints will be flat, and then use the 3M ruler with self-made door frame by precise leveling the steel wedge, should be in the process of levelingWhen the expansion joint is in position, the center line and elevation of the expansion joint should be adjusted, and the elevation is determined according to the measured road surface elevation in the 5m range on both sides of the seam.

The supply of the expansion joint of GQF-C type, GQF-Z type, GQF-F type, GQF-L type expansion device is composed of two side beams (C type, Z type, F type, L type of hot rolled section steel) and the rubber sealing belt。 It has the advantages of simple structure, convenient installation, suitable for the expansion of 0~80mm Bridge

A single group type expansion joint material: steel edge beam with steel rolling 16Mn, the Ministry is C shaped rubber sealing strip. The chloroprene rubber manufacturing, has good aging resistance, scratch resistant performance.

Solid anchor parts: there are three kinds of anchor bolts, anchor ring, anchor plate structure, design engineers can design the thickness of the bridge panel design, spacing is generally 20cm, the factory can also be designed according to the design engineer of a specific design.
