Large seamless anti-seismic expansion joint for bridge
The invention relates to a large seamless anti-seismic expansion joint for a bridge. The large seamless anti-seismic expansion joint comprises an expansion joint framework, a water seepage groove drainage assembly, a constant-section device, an aggregate assembly and a surface layer smoothing spring net. The expansion joint framework comprises a base and a lateral vertical steel plate; the constant-section device assembly comprises a joist body telescopic lifting device; the waterproof device comprises a water seepage and drainage diversion trench, an EVA plate (or an EP plate) and a fixing piece. The device has the beneficial effects that through the constant-section device, when a bridge deforms, the joist body can stretch and retract between the two expansion joint frameworks, and the stretching and retracting change between bridge gaps is absorbed; the joist bodies are horizontally combined to transfer force to complete lifting and stretching, and the aggregate assembly of the expansion joint is kept flush with the road surface.
本发明涉及一种桥梁大型无缝式抗震伸缩缝，包括伸缩缝骨架及渗水槽排水总成、恒等截面装置、骨料总成及表层抚平弹簧网；所述伸缩缝骨架包括底座及侧向竖直钢板；恒等截面装置总成包括托梁体伸缩升降装置；防水装置包括渗水排水导流槽、EVA板(或EP板)以及固定件；本发明的有益效果是：通过恒等截面装置，在桥梁变形时，托梁体可以在两根伸缩缝骨架之间伸缩，吸收桥梁缝隙间的伸缩变化；托梁体之间水平结合传力完成升降及伸缩，保持伸缩缝的骨料总成与路面齐平。
