Prefabricated part connecting piece and concrete prefabricated part connecting structure
The invention discloses a prefabricated part connecting piece and a concrete prefabricated part connecting structure. The connecting piece comprises a stopping piece, a positioning snap ring, a connecting plug and an elastic component for supporting the positioning snap ring; the connecting plug comprises a connecting end and a plugging end; the plugging end is provided with a necking part, an upper reducing part and a lower reducing part; the outer diameter of the upper reducing part is gradually increased downwards in the axial direction, and the outer diameter of the lower reducing part isgradually decreased downwards in the axial direction; the upper reducing part is provided with at least one circumferential annular groove which is formed by recessing inwards from the outer surface of the upper reducing part; and the inner wall of the positioning snap ring is provided with a contact part used for being tightly held on the outer surface of the upper reducing part and a supportingpart formed at the lower end of the inner wall and used for abutting against the inner side portion of the lower groove edge of the circumferential annular groove. The connecting piece disclosed by the invention can increase the pulling resistance, the moving distance of the connecting plug is reduced, and then the gap between the two prefabricated parts is reduced.
本发明公开了一种预制构件连接件及混凝土预制构件连接结构,所述连接件包括止挡件、定位卡环、插接头、以及支撑所述定位卡环的弹性部件;所述插接头包括连接端和插接端,所述插接端具有缩颈部、上变径部和下变径部;所述上变径部的外径沿轴向方向向下逐渐增大,所述下变径部的外径沿轴向方向向下逐渐减小;所述上变径部具有至少一道从其外表面向内凹进而形成的周向环形槽;所述定位卡环的内壁具有用于抱紧在所述上变径部的外表面上的接触部,以及形成在内壁下端处以用于抵接所述周向环形槽的下槽边的内侧部位的支撑部。该连接件可增加抗拔性,减少插接头活动距离,进而减小两个预制件之间的空隙。
