Hengshui Hao Tong | GQF-C40 bridge expansion | Pingliang bridge expansion project by Hao-rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, spherical steel bearing TS type bridge expansion joint device TS-type bridge expansion joint device, Tianjin and the Tianjin Municipal Engineering Institute of Highway Administration jointly developed to meet the amount of stretching in the range of 80 ~ 800mm modulus Series products. The structure is mainly composed of the following components: a waterproof seal system consists of neoprene sealing tape, layering and layering bolt constitute, shown in Figure 5-7. 2, side beams and side beams and anchoring systems anchoring system for the whole group, weldments, from the edge of the beam body, side beam anchors (anchor plate and anchor ring), the box (package extension box welded anchor bolts, single seam no such member) components. 3, elastic support system elastic support system consists of rigid beams and support beams in the middle, upper and lower bearing pads, control spring, namely the middle beam transverse arrangement, each intermediate beam spacing of 1600mm fixed number of roots support beam (beam - Editor's note), and to ensure the stability of motion in the middle of the beam. Support beams installed in the sliding elastic support mat. To prevent the lower bearing support beam left pad embedded with the elastic support beam supporting the upper end of the support beam compression pad to keep the ends of the supporting beams have a lasting clamping force. Between the support beams, set up a low-stiffness control spring between the support beams and side beams cabinet, to form an elastic chain effect. 4 lateral displacement control system lateral displacement control system consists of the guide sleeve, slide the middle of the beam axis and given their rings. The system is designed for the intermediate beam sports-oriented, middle beam transverse displacement when GQF-Z80 bridge expansion device, control its maximum displacement, keep the beam ends neatly arranged bridge expansion devices, each sealed with a guaranteed amount of displacement of the absorption ± 50mm. SSF-type bridge expansion joint device rubber seals rubber seals from bird-shaped rubber band and clip block (or layering), with the upcoming rubber bands pressed into the clamp block (or layering) of the grooves, clamp block (or clip strip) at a certain distance from the outer edge of the longitudinal modulus type E-type bridge expansion, steel bolt through the clamp block the rubber bands clamped beneath the middle of the beam or side beam flange GQF-C40 bridge expansion, as Figure 5-9 SSF-type bridge expansion joint device shows the maximum amount of displacement of 640mm. From 80 ~ 640mm, 80mm for the level to divide more than 640mm telescopic amount can be individually designed according to the needs.
