The invention relates to the technical field of building construction, and discloses a plugging method for an outer wall bolt hole. When an outer wall formwork is installed, a split bolt is sleeved with a positioning sleeve, and after concrete pouring is completed and the formwork is removed, the positioning sleeve is taken out of an outer wall. The taken-down positioning sleeve can be used for construction next time, and the construction cost is reduced. A plug is inserted into the end, located on the outer side of the outer wall, in the bolt hole, the end face of the plug is coated with a waterproof layer, and the sealing effect is guaranteed. The bolt hole is filled with a foaming agent, and an inner side hole opening of the bolt hole is filled with micro-expansion mortar so as to plug the bolt hole. The micro-expansion mortar can improve the strength of a wall body at the bolt hole, and the wall body has enough bearing force. According to the plugging method, the two sides of the bolt hole do not need to be plugged at the same time, and the construction efficiency is improved while the plugging leakproofness is guaranteed. In addition, the bolt hole plugging operation can be operated by means of a climbing frame, lifting of an attached lifting scaffold cannot be affected, and normal operation of other construction is guaranteed.
本发明涉及建筑施工技术领域，公开一种外墙螺栓孔的封堵方法，安装外墙模板时，在对拉螺栓上套设定位套管，混凝土浇筑完成并拆除模板后，将定位套管由外墙中取出。取下的定位套管可供下次施工使用，降低施工成本。在螺栓孔内位于外墙外侧的一端插入堵头，并在堵头端面处涂刷防水层，保证密封效果。在螺栓孔内填充发泡剂，并在螺栓孔的内侧孔口处填充微膨胀砂浆，以封堵螺栓孔。微膨胀砂浆能够增加螺栓孔处墙体的强度，保证墙体有足够的承受力。本发明无需在螺栓孔两侧同时进行封堵，保证封堵严密性的同时提高了施工效率。此外，本发明的螺栓孔封堵作业借助爬架即可操作，不会影响附着式升降脚手架的提升，保证其他施工正常进行。
