Unit beam type multidirectional displacement telescopic device
The invention discloses a unit beam type multidirectional displacement telescopic device. The device comprises unit beams, a damping displacement support, an inverted buckle chain plate, a concrete end supporting bracket, an inhaul cable device, a limiting device and a water stopping device, wherein the unit beams are fixed to the supporting brackets on the two sides of the beam end respectively and supported by the damping displacement supports, and the limiting devices and the inhaul cable devices are arranged between the movable unit beams to control transverse deformation; the unit beams are mutually staggered, mutually guided and mutually slide and stretch, so the joint-crossing stretching function of the stretching device is realized; the reverse buckling chain plates are connected to the ends of the telescopic unit beams and arranged between the fixed unit beams, the bottoms of the reverse buckling chain plates are buckled with the fixed unit beams, the unit beams and the reverse buckling chain plates form a beam-crossing seam structure plane flush with the road surface, and therefore smooth passing of vehicles is guaranteed. The device is advantaged in that driving comfortis improved, the structural size of a bridge expansion joint mounting groove is reduced, shock absorption and noise reduction are achieved, the requirements for multi-directional displacement of a beam body and large-span bridge structure displacement are met, and mounting, replacement and maintenance are facilitated due to the unitized design.
本发明公开单元梁式多向变位伸缩装置，包括单元梁、减震变位支座、倒扣链板、混凝土端支撑托架、拉索装置、限位装置、止水装置；单元梁分别固定在梁端两侧支撑托架上，采用减震变位支座支撑，活动单元梁之间设置限位装置和拉索装置，控制横向变形；单元梁相互交错、相互导向、相互滑动伸缩，实现伸缩装置的跨缝伸缩功能；倒扣链板连接在伸缩单元梁端部，置于固定单元梁之间，底部与固定单元梁相互扣接，单元梁和倒扣链板形成与路面平齐的跨梁缝构造平面，从而保证车辆的平顺通行。本发明提高行车舒适性，减少桥梁伸缩缝安装槽结构尺寸，减震降噪，满足梁体产生多向变位以及大跨径桥梁结构变位需求，且单元化设计便于安装更换维修。
