Support changing structure for dismantling partition wall of foundation pit and partition wall dismantling construction method
The invention discloses a support changing structure for dismantling a partition wall of a foundation pit and a partition wall dismantling construction method. The support changing structure comprises a force transmission component and support components arranged at the two ends of the force transmission component. The force transmission component penetrates through the partition wall, the two ends of the force transmission component are located in the basement structures on the two faces of the partition wall respectively, and the force transmission component and the corresponding basement structures are fixed through corresponding support components. During construction, when basement structures on the two sides of a partition wall are constructed, shear-resistant profile steel and a bottom plate are pre-buried in the basement structure needing to be provided with a second type of support component; then, the partition walls are dismantled layer by layer from top to bottom, and a support changing structure is constructed; after the partition wall is dismantled to a bottom plate on the lowermost layer of the basement structure, a post-cast strip formed at the position where the partition wall is dismantled is poured and sealed; and when the post-cast strip reaches the design strength, all the support changing structures are dismantled and recycled. Components of the basement structures on the two sides of the partition wall are used as force transmission supports, force transmission is clearer and more reliable, and the basement structures can be effectively connected and transmit horizontal force.
本发明公开了用于拆除基坑分隔墙的换撑结构及分隔墙拆除施工方法，包括传力构件，以及设置在传力构件两端的支座构件；传力构件穿过分隔墙，两端分别位于分隔墙两面的地下室结构内，均通过相应的支座构件与相应的地下室结构固定。施工时，在施工分隔墙两侧的地下室结构时，在需要设置第二种支座构件的地下室结构内预埋抗剪型钢和底板；然后，从上向下逐层拆除分隔墙并施工换撑结构；在将分隔墙拆除至地下室结构最下层的底板后，浇筑并封闭拆除分隔墙部位形成的后浇带；当后浇带达到设计强度后，拆除并回收所有换撑结构。本发明利用分隔墙两侧地下室结构的构件作为传力支座，传力更明确，更可靠，能够有效地使地下室结构实现连接并传递水平力。
