Piston type grouting sleeve suitable for precast concrete component and using method
The invention relates to the field of prefabricated buildings, in particular to a piston type grouting sleeve suitable for a concrete prefabricated component and a using method. The piston type grouting sleeve is arranged at the connecting end of the concrete prefabricated part and comprises a sleeve body arranged in the concrete prefabricated part, the first end of the sleeve body is connected with a first plug, the second end of the sleeve body is connected with a second plug, and a grouting hole and a grout outlet hole are formed in the sleeve body between the first plug and the second plug. The piston is installed in the sleeve and located on the side, close to the grouting hole, between the grouting hole and the grout outlet, and the grouting hole is located between the piston and the first plug. The first end of the connecting steel bar is connected with the piston, a through hole is formed in the middle of the second plug, and the second end of the connecting steel bar is inserted into the through hole of the second plug; and the first plug is connected with a stress connecting steel bar in the precast concrete component. A series of problems generated in the production, transportation and hoisting processes due to reserved exposed reinforcing steel bars are solved, and on-site cast-in-place wet operation is avoided.
本发明涉及装配式建筑领域，是一种适用于混凝土预制构件的活塞式灌浆套筒及使用方法。活塞式灌浆套筒设在混凝土预制构件的连接端，活塞式灌浆套筒包括置于混凝土预制构件内的套筒，在套筒第一端连接有第一堵头，在套筒的第二端连接有第二堵头，在第一堵头和第二堵头之间的套筒上设有注浆孔和出浆孔；活塞安装在套筒内，活塞位于注浆孔和出浆孔之间靠近注浆孔的一侧，注浆孔位于活塞和第一堵头之间；连接钢筋的第一端和活塞相连接，在第二堵头的中部设有通孔，连接钢筋的第二端插在第二堵头的通孔内；第一堵头和混凝土预制构件内的受力连接钢筋相连接。解决了预留外露钢筋导致的在生产、运输、吊装过程中产生的一系列问题，避免现场现浇湿作业。
