Integral falling frame dismantling method
The invention discloses an overall landing frame dismantling method, and relates to the technical field of overall landing frame construction. Comprising the following steps that before beam body concrete is poured, when top plate steel bars are bound, embedded parts are installed according to the designed position, and it is ensured that positioning is accurate; and the escalator well outer wall intruding into the horizontal projection range of the bailey beam is chiseled away, and the constant strength is restored to the original state after the support is dismantled. Field filling sand bags in the corresponding range of the lowering area are leveled; after beam body construction is completed, flange plate outer side formworks, side formwork area formworks and steel pipe supports are dismantled firstly; the overall falling frame device and the falling frame limiting device are installed, and pre-tightening trial hoisting is conducted; and the sand box is unloaded, the sand box, the transverse connecting system and the steel pipe buttress are dismantled, and the strip-shaped foundation is chiseled away. According to the dismantling method, the influence on the structure is reduced, the support is dismantled in a staged circulation mode, damage to the structure is reduced, and the stability of the structure is guaranteed; according to the overall falling frame dismantling method, waste generated is few, and pollution to the environment is reduced.
本发明公开了整体落架拆除方法，涉及整体落架施工技术领域。包括如下步骤：浇筑梁体混凝土前，顶板钢筋绑扎时，按设计位置安装预埋件，且确保定位精确；凿除侵入贝雷梁水平投影范围内的扶梯井外墙，待支架拆除完毕后等强恢复至原状。将下放区域对应范围的场地填筑砂袋进行平整；待梁体施工完成后，先拆除翼缘板外侧模、侧模区域模板及钢管支架；安装整体落架装置、落架限位装置，进行预紧试吊；砂箱卸载，拆除砂箱、横向连接系、钢管支墩，凿除条形基础。本发明的拆除方法，降低了对结构的影响，采用分阶段循环的方式进行支架拆除，减少了对结构的破坏，保证了结构的稳定性；整体落架拆除方法产生的废弃物少，减少了对环境的污染。
