Integrally rolled channel steel comb tooth type expansion joint device and construction method
The invention relates to the technical field of expansion joints, in particular to an integrally rolled channel steel comb tooth type expansion joint device and a construction method. The problems that according to a traditional expansion joint structure, concrete in an anchoring area is crushed, an expansion joint steel beam deforms and loosens, and a notch is prone to being filled with sundries are solved. The expansion joint device is installed on a prefabricated bridge deck slab, the expansion joint device comprises a groove-shaped steel beam, anchoring steel plates and polymer concrete, the groove-shaped steel beam is fixed to the multiple anchoring steel plates, and the multiple anchoring steel plates are evenly placed on the prefabricated bridge deck slab and fixed through the cast-in-place polymer concrete; the expansion joint devices are meshed with each other through the groove-shaped steel beams. The expansion joint device is clear and scientific in force transmission, simple in structure, convenient to produce and simple in field installation procedure, and meanwhile a large amount of later maintenance cost can be saved.
本发明涉及伸缩缝技术领域，具体为一种整体轧制槽型钢梳齿式伸缩缝装置及施工方法；解决了传统伸缩缝结构存在的锚固区混凝土被压碎、伸缩缝钢梁变形松动、槽口易填满杂物等问题。本伸缩缝装置安装于预制桥面板上，所述伸缩缝装置包括槽型钢梁、锚固钢板和聚合物混凝土，所述槽型钢梁固定于若干锚固钢板上，若干锚固钢板均匀放置于预制桥面板上，并通过现浇的聚合物混凝土固定；所述伸缩缝装置之间通过槽型钢梁相互啮合。本伸缩缝装置传力清晰科学，结构简单便于生产，现场安装工序简洁，同时可节省大量的后期养护成本。
