Blocking method for reserved hole of cantilever steel beam
The invention relates to building construction, in particular to a plugging method for a reserved hole of a cantilever steel beam. Comprising the following steps: S1, manufacturing a reserved box; s2, prefabricated blocks are manufactured; s3, scabbling treatment is conducted on the shear wall connecting part, a slope is formed through scabbling, and the slope faces the outer side; s4, mounting a cantilever steel beam and a reserved box; s5, shear wall steel bar binding and water and electricity pre-burying construction are conducted; s6, after shear wall steel bar binding and water and electricity pre-burying acceptance check are qualified, shear wall formworks are combined; s7, after construction of the main body structure is completed, the overhanging outer frame and the overhanging steel beam are dismantled, the reserved box is dismantled, the reserved hole is cleaned up, chiseling is conducted, and water is sprayed to wet an interface; and S8, the reserved holes are blocked through precast blocks, and caulking treatment is conducted through waterproof mortar. The prefabricated box is in a square horn mouth shape and is high inside and low outside, the situation that external seepage water permeates into a wall through an interface is avoided, and the construction quality is guaranteed; and during plugging, a plugging template does not need to be erected, so that the problem of difficult template removal is avoided, and the construction efficiency is improved.
本发明涉及建筑施工，特别是一种悬挑钢梁预留洞的封堵方法。包括如下步骤：S1、制作预留盒；S2、制作预制块；S3、剪力墙接茬部位进行凿毛处理，凿毛形成找坡，坡向外侧；S4、悬挑钢梁和预留盒安装；S5、剪力墙钢筋绑扎及水电预埋施工；S6、剪力墙钢筋绑扎及水电预埋验收合格后，合剪力墙模板；S7、主体结构施工完毕后拆除悬挑外架及悬挑钢梁，拆除预留盒且将预留洞清理干净并凿毛，洒水湿润界面；S8、用预制块对预留洞进行封堵，使用防水砂浆进行嵌缝处理。本发明的预制盒采用方喇叭口形，内高外低，避免了外部渗水通过界面渗入墙内的情况，保证施工质量；封堵时，不需要支设封堵模板，避免了拆模难的问题，提高了施工效率。
