Check whether the gap between the beam is in line with the requirements, if not in line with the need for processing has reached the requirements. Check the gap between the beam is in line with the requirements, if not in line with the need to handle has reached the requirements.

The check whether the corresponding embedded bar with a telescopic device anchoring ring, such as the existence of dislocation, phase torsion problems should be adjust the anchor ring. Check whether the corresponding pre buried steel and anchor ring expansion device, such as the existence of dislocation, phase torsion problems should be adjust the anchor ring.

How to ensure the effective connection of embedded steel ring and the welding seam, should be based on the actual size, preparation of a number of different specifications to ensure that the effective welded steel ring and embedded parts, should be based on the actual gap size, steel plate as liners. Steel as liners.

Check the concrete beam and the top beam at the end of the existence of defects, the defect should be reinforced. The top of the beam and end beam inspection of concrete defects, the defect should be reinforced.

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;
