Bridge expansion joints transmission bridge expansion joints J-75 multi-stitch comb plate drive mechanism bridge type bridge expansion joints device is determined by the control arm, a joystick and other ancillary pieces of composition. Joystick from beams in through the web, where and has a cylindrical bearing with, shown in Figure 5-4. Mechanical movement bridge expansion joints transmission mechanism will be as follows: the beam embedded in the body of the box led to the control arm, control arm forcing the lever rotates, pushing the joystick to slide axially along the bridge beams, beams, while promoting the lateral stringers parallel movement. Bridge expansion joints rubber seals by Yan-shaped rubber strip with stainless steel clip strip and clamp blocks. Side of the block is about to rubber bridge expansion joints with tooth pattern is pressed into the inner recesses of the SCB clip comb plate joints, clamp bands every certain distance from the outer edge of the longitudinal sleeve to clamp blocks, with a stainless steel bolt through the clamp block 80 comb plate joints, the rubber grip on the stringers beneath the flange, as shown in Figure 5-5 XF-type bridge expansion joint device bridge expansion joints belong to the oblique-bearing bridge expansion joint device is determined by the Ministry of Railways research CRCC the hospital, Hebei Hengshui City Rubber Co., Ltd. and Shijiazhuang Traffic Survey and Design Institute in 1993 jointly developed the Modular series. Structural characteristics and principles of bridge expansion joints: bridge expansion joints, mainly by the side beams, the beams, the sealing rubber band, diagonal support beams, pressure and compression mount, displacement control box and anchor steel components. Its side beams and the beams are made of shaped steel domestic extruded. Its cross section is arranged as shown in Figure 5-12. SF comb plate joints, Tianjin comb plate joints, the manufacturer provided by the Engineering Rubber Co., Ltd. Hengshui HaoTong. Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
