Prepressing device and prepressing method for cast-in-place bracket of continuous rigid frame bridge
The invention belongs to the technical field of building construction, and particularly relates to a continuous rigid frame bridge cast-in-place bracket pre-pressing device and a pre-pressing method.The continuous rigid frame bridge cast-in-place bracket pre-pressing device comprises a bridge pier body and a plurality of bracket bodies, the bracket bodies are poured on the side wall of the bridge pier body through concrete, and I-shaped steel is installed above each bracket body; the I-shaped steel is used for supporting the bracket body, a plurality of supporting frames are arranged above the I-shaped steel, a pre-pressing mechanism is arranged between every two adjacent supporting frames, and the pre-pressing mechanisms are used for pre-pressing the cast-in-place bracket; through the use of the pre-pressing mechanism, the pressure can be automatically controlled according to the force borne by the bracket body on site, the inelastic deformation of the bracket body is eliminated, the bracket body and the I-shaped steel cannot be damaged, and the situation that when a jack is used for pre-pressing the bracket, pre-pressing data needs to be accurately controlled is also avoided; and the problem that concrete is likely to crack when errors occur is solved, and convenience is brought to continuous construction of the subsequent continuous rigid frame bridge.
本发明属于建筑施工技术领域，具体的说是一种连续刚构桥现浇托架预压装置及预压方法，包括桥墩本体和多组托架本体，多组所述托架本体通过混凝土浇筑在桥墩本体的侧壁，每组托架本体的上方均安装有工字钢，所述工字钢用以对托架本体支撑，所述工字钢的上方设置有多个支撑架，相邻所述支撑架之间设置有预压机构，预压机构用以对现浇托架进行预压；经过预压机构的使用，能根据现场托架本体所能承受的力来自行控制压力，消除了托架本体的非弹性形变，不会对本身的托架本体以及工字钢造成毁坏，也避免了使用千斤顶来对托架进行预压时，需要精确控制预压数据，出现错误时可能导致混凝土脱裂的问题，为后续连续刚构桥的继续施工带来了便捷性。
