Polyurethane elastomer seamless expansion device and construction process thereof
The invention discloses a polyurethane elastomer seamless expansion device and a construction process thereof, and belongs to the field of bridge structures, gaps of an original expansion joint structure are filled with filler, and the filler and the organic cementing material are used for bonding and fixing, so that concrete is convenient, the blank of the original gaps is filled, and the stability of the structure is ensured; a polyurethane elastomer is laid on the upper portion of the whole structure, a spring box-steel plate device is arranged, and the requirement for large-size deformation of the bridge expansion joint can be met. The cross-joint steel plate is arranged in the middle of the structure to resist pressure, and the defects that a traditional expansion joint structure is insufficient in structural rigidity, insufficient in anchoring component strength and prone to damage to different degrees in the operation process can be overcome, so that the strength of a bridge structure with a large span is improved, and the service life of the bridge structure is prolonged.
本发明公开了一种聚氨酯弹性体无缝伸缩装置及其施工工艺，属于桥梁结构领域，本发明在原有的伸缩缝结构的缝隙内填充有填充物，并用有机胶结材料进行粘接固定，方便混凝土的同时，填补了原有缝隙的空白，保证了结构的稳定性；整体结构上方铺设聚氨酯弹性体、并且设置弹簧箱‑钢板装置，能够满足桥梁伸缩缝较大尺寸的形变。在结构中间设置跨缝钢板抗压，能弥补传统伸缩缝结构本身构造刚度不足、锚固的构件强度不足，在营运过程中产生不同程度的破坏的缺点从而增加跨径较大的桥梁结构的强度、使用寿命。
