Prefabricated concrete connecting piece and prefabricated concrete pile
The invention discloses a prefabricated concrete connecting piece and a prefabricated concrete pile. The prefabricated concrete connecting piece comprises an inserting rod, an umbrella rib cylinder, a first fixing sleeve and a second fixing sleeve, wherein the inserting rod comprises a base and an inserting head arranged on the base; the umbrella rib cylinder comprises a sleeve-shaped umbrella rib cylinder body and a plurality of elastic umbrella rib teeth uniformly distributed at one end of the umbrella rib cylinder body, the elastic umbrella rib teeth are outwards expanded in the radial direction of the umbrella rib cylinder body from one end of the umbrella rib cylinder body to the free end of the umbrella rib cylinder body, and the end face of the free end of each elastic umbrella rib tooth is an abutting face; the umbrella rib cylinder sleeves the inserting head and is fixedly connected with the inserting head through the umbrella rib cylinder body; an annular clamping groove is formed in the inner side wall of the second fixing sleeve, a clamping face is arranged in the annular clamping groove, and the abutting face of each elastic umbrella rib tooth abuts against the clamping face when the inserting rod is inserted into the second fixing sleeve. The prefabricated concrete connecting piece has the advantages of being simple in structure, high in connecting strength and tensile bearing capacity, low in cost and the like.
本发明公开了预制混凝土连接件和预制混凝土桩,其中连接件包括,插杆、伞骨筒、第一固定套筒和第二固定套筒;插杆包括底座和设置在底座上的插头;伞骨筒包括套筒状的伞骨筒本体和均布在伞骨筒本体一端的多个弹性伞骨齿,弹性伞骨齿由伞骨筒本体一端向自由端沿伞骨筒本体径向方向向外张开,弹性伞骨齿的自由端的端面为抵接面;伞骨筒套在所述插头上,并通过伞骨筒本体与插头固定连接;第二固定套筒的内侧壁上设有环形卡槽,环形卡槽内设有卡接面,插杆插入第二固定套筒中时,弹性伞骨齿的抵接面与所述卡接面抵接。该预制混凝土连接件具有结构简单,连接强度和抗拉承载力高,以及成本低等优点。
