Oil pressure anchoring type steel bar connecting sleeve and connecting method
The invention relates to the technical field of prefabricated concrete member construction, in particular to an oil pressure anchoring type steel bar connecting sleeve and a connecting method.The two ends of two sleeves connected in a threaded mode are fixedly connected with a steel bar in a threaded mode, and a piston in a second sleeve is pushed to move from the rear end to the front end by injecting oil into the first sleeve for pressurization; when the reinforcing steel bar is inserted into the front end of the wedge-shaped buckle, thrust is formed at the tail end of the wedge-shaped buckle, the wedge-shaped buckle is gradually tightened when moving outwards along the front end, the reinforcing steel bar inserted into the front end is meshed and fixed, and when the reinforcing steel bar is subjected to external tension, the reinforcing steel bar and the second internal thread on the wedge-shaped buckle can drive the wedge-shaped buckle to move outwards together; the inner diameter of the front end is gradually shrunk outwards, so that the occlusal force can be increased when the reinforcing steel bars to be connected are subjected to external force, reliable reinforcing steel bar fixation is formed, sleeve grouting is omitted, the reinforcing steel bars are firmly connected, and the tightness of sleeve reinforcing steel bar connection is improved.
本发明涉及预制混凝土构件施工技术领域，尤其涉及一种油压锚固式钢筋连接套筒及连接方法，本申请通过螺纹连接的两个套筒，两端分别与钢筋以螺纹固定连接，通过在第一套筒内注油加压，推动第二套筒内的活塞在后端向前端移动，对楔形卡扣的末端形成推力，楔形卡扣沿前端向外移动时逐渐收紧，对插入到前端的钢筋进行咬合固定，并且钢筋受到外部拉力时，因与楔形卡扣上的第二内螺纹进行了固定，会一并带动楔形卡扣向外移动，而前端的的内径向外是逐渐收缩的，所以待连接钢筋受外力时会增加咬合力，形成可靠的钢筋固定，从而达到了免去套筒灌浆实现钢筋连接紧固，提高套筒钢筋连接的紧密性。
