Foundation pit partition wall support changing structure and support changing construction method for dismantling foundation pit partition wall
The invention discloses a support changing structure for a partition wall of a foundation pit and a support changing construction method for dismantling the partition wall of the foundation pit, and the support changing structure is arranged between two structural columns, two structural beam plates or one structural column and one structural beam plate and comprises H-shaped steel and a first support and/or a second support; the first support is connected with a corresponding structural column through a steel anchor plate; the second support is of a steel corbel structure; the distance between each first support and the foundation pit partition wall is within half of the span distance of the corresponding structural columns. During construction, a foundation pit partition wall and a basement structure are constructed firstly, and a second support is arranged; dismantling the foundation pit partition wall from top to bottom when dismantling conditions are met; dismounting to the top surface of each structural beam plate needing to be subjected to construction support replacement, and arranging corresponding first supports and H-shaped steel; and finally, the post-cast strip is cast, and after the requirement is met, the recovered H-shaped steel is dismantled. When the method is implemented, large or special equipment is not needed; the formed structure is clear in force transmission, high in operability, high in implementation speed, economical in material consumption and capable of being recycled.
本发明公开了基坑分隔墙换撑结构及拆除基坑分隔墙的换撑施工方法，设置在两根结构柱之间、两个结构梁板之间，或者一个结构柱和一个结构梁板之间，包括H型钢，及第一支座和/或第二支座；第一支座通过钢锚板与相应的结构柱连接；第二支座为钢牛腿结构；每一第一支座与基坑分隔墙的距离均在相应的所述结构柱跨间距的一半以内。施工时，先施工基坑分隔墙及地下室结构，设置第二支座；满足拆除条件，自上而下拆除基坑分隔墙；拆至每一需施工换撑的结构梁板的顶面，设置相应第一支座和H型钢；最后，浇筑后浇带，当达到要求后，拆除回收H型钢。本发明实施时无需大型或特殊设备；形成的结构传力明确，可操作性强，实施速度快，用料经济，可实现回收。
