TS-type bridge expansion joint device bridge expansion joints, Tianjin and the Tianjin Municipal Engineering Institute of Highway Management Office jointly developed, bridge expansion joints to adapt to the amount in the range of 80 ~ 800mm of Modular products. Its structure is mainly composed of the following components: a bridge expansion joint sealing waterproofing system from neoprene sealing tape, layering and layering bolt constitute bridge expansion joints, shown in Figure 5-7. 2, bridge expansion joints and anchoring systems side edge beam beams and anchoring system for the whole group weldment bridge expansion joint strip, that is, from the edge of the beam body, side beam anchors (anchor plate and anchor ring), box (package Extension Box welded on the anchor bolts, single slit is no such member) component. 3, the elastic support system expansion joints connected by a rigid main beams and support beams in the middle, upper and lower bearing pads, control spring, namely the middle beam horizontal arrangement, each intermediate beam spacing of 1600mm fixed number of roots support beams (beams - - Editor's note), and to ensure the stability of motion in the middle of the beam. Girder bridge expansion joints installed in the sliding elastic support pad. 4 lateral displacement control system bridge expansion joints lateral displacement control system consists of the guide sleeve, sliding shaft and intermediate beam given their rings. The system is oriented gqfz intermediate girder type bridge expansion joints for movement, while the middle beam transverse displacement control its maximum displacement, holding beam ends neatly arranged cqfc40 type bridge expansion joints, sealing tape to ensure that each absorbed ± 50mm shift amount. Control Systems Control Systems bridge expansion joints displacement SG-type bridge expansion joint device is divided into two in parts: First, anchor bolts provided in the side and bottom surfaces of the beams supporting the activities beams, both to control the whole match the maximum amount of displacement ; the second is provided on the web bolt retainer split-beam, the bridge expansion joints to limit the gap when stretched to the maximum value from the bolt, compression to a minimum when touching the spring seat to control. In addition, the bridge expansion joints within the web in the spring seat set mandrel rod, together with specially designed springs to control the displacement equidistant between units (ie, the guarantee of uniformity of each slit stretching method - manufacturers Note) constructed As shown in Figure 5-10. gqfz type bridge expansion joints, Hao-engineering rubber (certified), bridge expansion joints supplied by Engineering Rubber Co., Ltd. Hengshui HaoTong. Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) in the field of construction materials at the site devoted boundless enthusiasm and passion, Hao-engineering rubber has been customer-centric, the concept of creating value for customers, quality, service to win the market, and sincerely hope to cooperate with the community to create a successful, create brilliant.
