Basement exterior wall single-face formwork supporting system and construction method thereof
The invention discloses a basement exterior wall single-face formwork supporting system. The basement exterior wall single-face formwork supporting system comprises multiple split screws and steel pipe inclined struts. An embedded steel bar is welded to one end of each split screw, and the other ends of the embedded steel bars are connected with the inner side of an underground supporting pile. One ends of the steel pipe inclined struts are fixedly connected with the side of a basement exterior wall, and the other ends of the steel pipe inclined struts are connected with the top ends of steelbar ground anchors pre-buried on the inner sides of a basement bottom plate. Hanging net grout spraying is arranged on the outer side of the underground supporting pile, and a full rack is arranged atthe top of the basement bottom plate. In the basement exterior wall single-face formwork supporting system, during basement exterior wall single-face formwork construction, inclined steel pipes withgood rigidity are used for transmitting transmitted horizontal lateral pressure to the ground anchors, horizontal force is converted into pressure to the building ground and shear force to the groundanchors, embedded bars on the supporting piles and the split screws planed on the concrete side face of the exterior wall are used for connecting and butt welding, an exterior wall formwork is reinforced, operation is overall safe and firm, stability is good, and the phenomenon that formwork exploding and formwork expanding happen during concrete pouring is avoided.
本发明公开了一种地下室外墙单面支模支撑体系，包括若干根对拉螺杆与钢管斜撑，每根对拉螺杆的一端均焊接有植筋钢筋，且植筋钢筋的另一端与地下支护桩的内侧相连接，钢管斜撑的一端与地下外墙的侧边固定连接，钢管斜撑的另一端与预埋在地下室底板内侧的钢筋地锚的顶端相连接，地下支护桩的外侧设置有挂网喷浆，地下室底板的顶部设置有满堂架；本发明中地下外墙单面支模施工时，利用刚度较好的斜向钢管将外墙传来的水平侧压力传至地锚上，将水平力转化为对楼地面的压力和对地锚的剪力，利用支护桩上植筋和外墙混凝土侧面上种上对拉螺杆进行连对焊，加固外墙模，整体安全牢固，稳定性好，避免了混凝土浇筑时发生爆模、涨模现象。
