Plugging and reinforcing method for prefabricated shear wall cantilever I-steel reserved hole
The invention provides a plugging and reinforcing method for a prefabricated shear wall cantilever I-steel reserved hole, and relates to the technical field of reserved hole plugging. The method comprises the steps that sleeves are installed in an upper shear wall and a lower shear wall at the position of an I-shaped steel reserved hole respectively, and grouting holes are formed in the upper shear wall. And after the cantilever I-shaped steel is detached, the threaded rod is in threaded connection in the sleeve. And a heat preservation plate is used for blocking an outer side end opening of the I-shaped steel reserved hole, an inner side formwork is used for blocking an inner side end opening of the I-shaped steel reserved hole, an expansion bolt is arranged in the I-shaped steel reserved hole, and the two ends of the expansion bolt are fixedly connected with the heat preservation plate and the inner side formwork correspondingly. Grouting materials are injected into the I-shaped steel reserved hole through the grouting holes, the inner side formwork is dismantled after the grouting materials are formed, and plugging and reinforcing of the I-shaped steel reserved hole are completed. The characteristics of the fabricated shear wall are combined, the plugging effect is better, and the performance of the wall body is guaranteed.
本发明提供一种装配式剪力墙悬挑工字钢预留洞封堵加固方法，涉及预留孔封堵技术领域。本方法包括在工字钢预留洞位置的上、下剪力墙内分别安装套筒，并在上剪力墙上开设注浆孔。悬挑工字钢拆除后，在套筒内螺纹连接螺纹杆。使用保温板对工字钢预留洞的外侧端口进行封堵，使用内侧模板对工字钢预留洞的内侧端口进行封堵，并在工字钢预留洞内设置膨胀螺栓，将膨胀螺栓的两端分别与保温板、内侧模板固定连接。通过注浆孔向工字钢预留洞内注入灌浆料，待灌浆料成型，拆除内侧模板，完成工字钢预留洞的封堵加固。本发明结合了装配式剪力墙的特性，封堵效果更好，并保障了墙体本身的性能。
