Combined type semi-continuous UHPC bridge floor connecting plate telescopic device and construction method thereof
The invention provides a combined type semi-continuous UHPC bridge deck connecting plate telescopic device and a construction method thereof. The combined type semi-continuous UHPC bridge deck connecting plate telescopic device comprises a bridge abutment-main beam and a bridge deck continuous seamless structure based on corrugated steel bars and arranged between the bridge abutment-main beam. A semi-continuous UHPC board used for connection is arranged between the bridge abutment and the main beam, and a T-shaped area from the interior of a UHPC board groove to the bottom of the combined pavement layer is made of polyurethane materials. According to the technical scheme, the rigidity of the wiring position can be effectively improved, the overall vertical rigidity and strength of the connecting structure are improved, and the connecting structure is matched with the vertical rigidity of a bridge floor.
本发明提供了一种组合式半连续UHPC桥面连接板伸缩装置及其施工方法，包括桥台‑主梁以及桥台‑主梁之间的基于波折形钢筋的桥面连续无缝构造；所述桥台与主梁之间设置有用于连接的半连续UHPC板，UHPC板槽内至组合式铺装层底部的“T形区域”均为聚氨酯材料。应用本技术方案可有效提升接线处的刚度，提高连接结构的整体竖向刚度和强度，使其与桥面的竖向刚度匹配。
