Connecting structure for prefabricated part, prefabricated part and prefabricated pile combination
The invention discloses a connecting structure for a prefabricated part. The connecting structure comprises an embedded connecting sleeve, a tightening part and an insertion stress rib, wherein the embedded connecting sleeve is provided with a conical plugging channel of which the aperture is gradually increased in the depth direction of the sleeve, the tightening part is matched with the conical inserting channel and comprises more than two arc-shaped clamping blocks which are sequentially arranged in the circumferential direction, the insertion stress rib can prop open the arc-shaped clamping blocks originally gathered in the conical insertion channel to be inserted into the embedded connecting sleeve in the forward direction and are gathered by the arc-shaped clamping blocks along the conical insertion channel to lock the insertion stress rib in the reverse direction, the minimum arc radius of the inner wall of each arc-shaped clamping block is 0.8-1.3 times of the radius of the insertion stress rib, originally gathered arc-shaped clamping blocks are encircled to form a quasi-circular hole with more than two sections of arcs on any cross section, and the connecting structure for the prefabricated part has the advantages of being high in connecting reliability and good in stability. The invention further discloses the prefabricated part comprising the connecting structure for the prefabricated part and a prefabricated pile combination.
本发明公开了一种预制构件用连接结构，其包括：预埋式连接套筒，开设有孔径沿筒深方向逐渐增大的锥形插接通道；束紧部件，与所述锥形插接通道相适配且包含两个以上沿周向依次排列的弧形夹持块；以及插接受力筋，其能够撑开原本聚拢在锥形插接通道的弧形夹持块以正向插入所述预埋式连接套筒内且被各弧形夹持块沿锥形插接通道聚拢以逆向锁止插接受力筋；其中，所述弧形夹持块的内壁最小圆弧半径为插接受力筋半径的0.8倍～1.3倍；原本聚拢的弧形夹持块环绕形成一个在任意横截面上具有两段以上圆弧的类圆形孔。此种预制构件用连接结构具有连接可靠性高，稳定性好的有点。另外，本发明还公开了包含前述预制构件用连接结构的预制构件和预制桩组合。
