PC structure grouting sleeve connection construction method
The invention belongs to the field of structural connection of fabricated buildings, particularly relates to a PC structure grouting sleeve connection construction method, and aims to solve the technical problems that the field connection quality is difficult to meet the design requirement due to less research on the existing field connection construction process of the fabricated building structure and lack of strict field construction quality control regulations and specifications. According to the scheme, one end of grouting sleeve connection is connected through sleeve grouting, when a component is hoisted, a ribbed steel bar reserved in a base layer needs to be inserted into a reserved sleeve of a PC component, then the position of the steel bar is adjusted through the modes of perpendicularity, elevation, positioning and the like, the component is temporarily fixed, after the strength of a grouting material meets the requirement, grouting material mixtures are injected through grouting holes, grouting is stopped when grout flows out of the grout outlets, and the grouting holes and the grout outlets are blocked. The basic materials of the grouting materials are cement, and the grouting materials also comprise an additive, fine aggregate and other materials, and a proper amount of water is added and stirred.
本发明属于装配式建筑的结构连接领域，尤其是PC结构灌浆套筒连接施工工法，针对现有对装配式建筑结构现场连接的施工工艺研究较少，缺少严格的现场施工质量控制规程和规范，使得现场连接质量难以达到设计要求的技术问题，现提出以下方案，本发明中的灌浆套筒连接为一端利用套筒灌浆连接，当吊装构件时，需在PC构件预留套筒中插入基层预留的带肋钢筋，然后通过垂直度、标高、定位等方式调整钢筋的位置，对构件临时固定，当注浆材料强度达到要求后，将灌浆料拌合物通过灌浆孔注入，当出浆口流出浆液后停止注浆，并将灌浆孔和出浆孔封堵。灌浆材料的基本材料为水泥，此外还有外加剂、细骨料和其他材料，加入适量的水搅拌。
