Foundation pit supporting steel formwork for constructional engineering
The invention discloses a constructional engineering foundation pit supporting steel formwork and relates to the field of foundation pit protection, the constructional engineering foundation pit supporting steel formwork comprises a concrete block, side grooves are formed in the periphery of the upper end of the concrete block, mounting base mechanisms are fixedly connected to the inner walls of the side grooves in a clamped mode, and lifting mechanisms are fixedly connected to the upper sides of the mounting base mechanisms; and one side of the lifting mechanism is fixedly connected with a steel plate overturning mechanism. The telescopic shear type frame is gradually unfolded after being stressed, so that the folded side baffle sets are gradually unfolded, the two second hydraulic cylinders push the horizontal side baffle sets to be attached to the inner wall of a foundation pit, supporting of the inner wall is achieved, the two telescopic multi-stage arms increase horizontal stress on the backs of the first square plate and the second square plate correspondingly, and the structural strength of the unfolded horizontal side baffle sets is improved; the number of the steel formworks is reasonably planned according to the length of the inner wall of the foundation pit, each steel formwork is rapid to unfold and contract, a large amount of time and energy are not needed, mounting and dismounting are convenient, and the dismounting and mounting period is greatly shortened.
本发明公开了一种建筑工程基坑支护钢模板，涉及基坑防护领域，包括混凝土块，所述混凝土块的上端四周分别设置有侧槽，所述侧槽的内壁固定卡接有安装底座机构，所述安装底座机构的上侧固定连接有升降机构，所述升降机构的一侧固定连接有翻转钢板机构。本发明通过伸缩剪式架受力后逐渐展开，使得折叠的侧挡组逐渐展开，两个第二液压缸推动水平侧挡组贴合基坑内壁，实现对内壁的支撑，两组伸缩多级臂分别在第一、二方板的背部增加水平应力，提高展开后水平侧挡组的结构强度，根据基坑内壁长度合理规划该钢模板的数量，每个钢模板展开和收缩快速，无需大量时间和精力，安装拆卸方便，大幅缩短拆装周期。
