Sleeve for connecting prefabricated concrete uplift pile reinforcing steel bars
The invention relates to a sleeve for connecting prefabricated concrete uplift pile reinforcing steel bars, which comprises a hollow cylinder body, an inner cavity of the upper part of the hollow cylinder body is provided with internal threads, an inner cavity of the lower part of the hollow cylinder body is of an inverted conical structure, and at least three wedge-shaped clamping pieces are arranged in the inner cavity of the lower part of the hollow cylinder body. According to the sleeve for connecting the prefabricated concrete uplift pile reinforcing steel bars and the reinforcing steel bars, the prestressed reinforcing steel bars in the pile head are connected with the extension reinforcing steel bars through the sleeve, no matter how the pile head is damaged, as long as pile head concrete can be stripped and the prestressed reinforcing steel bars in the pile head are exposed, the reinforcing steel bars in the pile body can be in lap joint with the main reinforcing steel bars; and the problems of time consumption, labor consumption and material consumption caused by conventional welding connection are avoided.
本发明涉及一种用于预制砼抗拔桩钢筋与钢筋连接的套筒，包括：中空筒体，所述中空筒体的上部分内腔具有内螺纹，所述中空筒体的下部分内腔呈倒锥形结构，所述中空筒体的下部分内腔内设有至少三个楔形卡件。本发明提供的用于预制砼抗拔桩钢筋与钢筋连接的套筒，将桩头内部的预应力钢筋与接长钢筋采用套筒连接，无论桩头如何破坏，只要能剥除桩头混凝土，露出内部预应力钢筋，既可以将桩身内部钢筋与主体钢筋搭接，避免了常规焊接连接带来的费时、费力、费材料问题的发生。
