Screw hole plugging joint and construction method thereof
The invention discloses a screw hole plugging joint and a construction method thereof. The screw hole plugging joint comprises an outer wall and a screw hole horizontally formed in the outer wall, a plugging block is arranged in the screw hole, the plugging block is in a columnar shape with one end thicker than the other end, one end of the plugging block is matched with the screw hole in shape, the other end of the plugging block is thinner than the diameter of the screw hole, an air vent in the length direction is formed in the middle of the plugging block, a gum injection gap is formed between the plugging block and the outer wall, a waterproof air-isolating film is pasted to the indoor side of the screw hole, and polyurethane waterproofing paint is brushed to the outdoor side of the screw hole. The plugging block is directly prefabricated, the plugging block is placed in the screw hole, then gum injection is carried out, compared with the mode that sand, cement, gum, an expanding agent and water are injected into the screw hole after being stirred, the method has the advantages that the construction is easy, the operation is convenient, the plugging tightness degree of the screw hole is good, rainwater invasion can be avoided in the waterproof problem, and the later-period maintenance cost is saved.
本发明公开了一种螺杆洞封堵节点及其施工方法，包括外墙、水平开设在外墙上的螺杆洞，所述螺杆洞内设置有封堵块，所述封堵块呈一端粗于另一端的柱状，封堵块的一端与螺杆洞的形状匹配，另一端细于螺杆洞的直径，所述封堵块的中部具有沿长度方向的透气孔，封堵块与外墙之间具有注胶，螺杆孔的室内侧粘贴防水隔气膜，螺杆孔的室外侧涂刷聚氨酯防水涂料，直接预制封堵块，将封堵块放入螺杆洞内，再进行注胶，相比于用砂、水泥、胶、膨胀剂和水搅拌后在注入螺杆洞内，具有施工简单，操作方便，且螺杆洞的封堵严密程度好，并且防水问题上能够避免雨水侵入，节省后期的维修成本。
