Support mechanism single slit type bridge expansion joint device from the direction parallel to the bridge bridge expansion joints, using thick steel plate welded longitudinal steel beams (currently used in the overall shape of profiled steel, referred stringer) and parallel to the bridge axis direction The lateral support girder (referred to as beam) formed. The side sill and the side sill and the side is divided into different forms of cross-section of the stringer. For single stitch, located only side rails, no stringers and beams in its construction layout shown in Figure 5-1. Expansion joint support mechanism multi-slit apparatus shown in Figure 5-2. J-75 multi-slotted expansion joint device, due to the need to construct on the stringer to Figure 5-3 arrangement is connected to the contact with the beam. That is the number of beams in each group and the number of roots equal stringers. 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 weldment Modular bridge expansion, that is, from the edge of the beam body, side beam anchors (anchor plate and anchor ring), box (the box on the package extension welded anchor bolts, single slit is 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 c80 control spring bridge expansion 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 during bridge expansion c60, control its maximum displacement, keep the beam ends neatly arranged, guaranteed ± 50mm displacement of the absorption band of each seal.
