Supply V-type galvanized metal type bridge expansion W-type bridge expansion device manufacturers

Supply V-type galvanized metal type bridge expansion W-type bridge expansion joints installed manufacturers a, during installation, according to the actual temperature value to determine the mounting width. b, expansion joints installation process, you must use the expansion joint device neatly arranged, to maintain a certain inclination. Telescopic device to ensure the highest plane and finished flush with the deck. c, construction methods ① clean up a notch, so as to achieve design width and depth, clear and displacement have reinforced box buried interference, reserved open pit must be greater than the width of expansion joints installed. ② Check whether the beam between the telescopic device installation space meet the temperature requirements, otherwise, the application level jack, adjust the clamp until it meets the design requirements, adjusted immediately after the placement of special fixtures. ③ joints central location settings lifting apparatus, the telescopic device security within the notch and retractable top surface of the deck means the same elevation. Also note that slope aspect should also be consistent with the deck. ④ telescopic device after lifting the reserve tank, its center should be reserved space end of the beam center line on the positive, the length and width of the bridge on the positive. ⑤ on the telescopic device to adjust the line segments, and each stringer gap uniform. ⑥ telescopic device again in the box or anchor plate at vertical welding Ф16 reinforcement height above position, horizontal welding Ф16 steel bar width positioning. ⑦ after anchoring telescopic device is properly seated, they can anchor bars and reservation slot reserved telescopic device side welded steel telescopic device to ensure that the fixed line and leveling, as long as every 2 to 3 anchor tendons welding a welding you can, and then press the steps above welding anchor rib on the other side. After the two sides reached fixed, you can rest anchoring tendons further welding welding, ensure reliable anchor. When welding anchor tendons do not pay attention to the side beams and the beam welding of any construction to prevent deformation of twisted steel beams. ⑧ telescopic device if the sub-installation, the seams must be welded, welding should be professionals, each beam welding is completed, then step ⑦ anchored. ⑨ A slot reserved for the slot dimensions and production templates, the template should be put away after blocking tight to prevent water slurry flows into the displacement tank, expansion joints on flat stamped plate to prevent falling into the rubber seal with mortar, in the inspection apparatus after whether the correct flatness and neutral position, and are in line with the requirements of the gap before poured concrete, and concrete vibrators fully compacted, with particular attention to the displacement tank and the reserve pit base can not stay empty. To be removed after the concrete curing fixed card templates and expansion joints on. ⑩ before concrete expansion joints does not reach 80% of the strength, expansion joints can withstand external loads.
