Installation, debugging, installation of telescopic device, less than.

A telescopic device should be installed before the flatness inspection, flatness of steel should be controlled within 3mm. The expansion device is installed before the deal with the smoothness of the check,

The actual beam temperature determination of the on-site construction, according to the design of the temperature set the width value, adjust the installation beam temperature field measurement of the actual temperature, according to the construction design given set the width value, a width value of a width value.

The expansion device before installation, check whether the gap between the beam width expansion clean, whether it meets the requirements, expansion device of telescopic device before installation, check whether the gap between the beam width expansion clean, whether it meets the requirements, and sew, then put the fixture intact. For installation. And sew uniform then, install the fixture intact. For installation.

If the assembly is long telescopic device at the scene, the first docking two joints on the plane at the same level. Weld with double groove with open, double-sided welding, welding and welding to the top, side, bottom layer. Finally welding welding, ensure the quality of export by the same double groove. Open, double-sided welding, welding and welding to the top, side, bottom layer. Finally welding welding, ensure the quality. The connecting plate reinforcement; and the timely removal of welding slag, weld surface will be removed, after the inspection can be installed. And the connecting plate 200 x 50 x 16 reinforcement;
