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;
Telescopic lifting device in place, with not less than 3 metres in length, type of not less than 20# channel, with the form of double limb, telescopic device of lifting in place, the channel in the form of double leg, meters, perpendicular to the stretching device, is arranged on the deck. Then the T-shaped bolt telescopic device lift lift bolt expansion device, at intervals of 1 meters distance, perpendicular to the expansion device in the deck. Then the T-shaped bolt expansion device is fixed on the lift, channel. Both sides of the road and to press joint telescopic device channel and telescopic contact tightly fixed in the groove (steel and steel joints on both sides of the road.The surface and the expansion device to press contact tightly (when the structure of asphalt concrete pavement structure of new paving, considering the asphalt concrete due to compaction, compaction and height change, asphalt concrete structure, considering the asphalt concrete due to compaction, compaction and height change, the expansion device is appropriate). To ensure the expansion device in transverse direction and longitudinal direction are vertical joints after installation.). To ensure the expansion device in the transverse direction and the longitudinal seam are slightly lower than the road vertical direction of 1 ~ 2mm is appropriate). After installation to ensure the expansion device seam direction and vertical direction in the transverse and longitudinal suture after installation within the scope of the real ~.The elevation of the telescopic device is determined according to the measured road surface elevation in the 5m range on both sides of the seam.
