Snap-type connectors and connecting piles

Abstract

The invention discloses an ejecting clamping type connecting piece and a connecting pile. The ejecting clamping type connecting piece comprises a large nut sleeve, a small nut sleeve, a connecting piece and an insertion rod. The large nut sleeve is connected with the connecting piece in a threaded mode. A plurality of bent ejecting sheets are arranged on the side, contained in the large nut sleeve, of the connecting piece in an annular-array mode, and the included angles between the bent ejecting sheets and the inner side wall of the large nut sleeve are larger than 0 degree. One side of the insertion rod is connected with the small nut sleeve in a threaded mode, an annular groove is formed in the outer circumference face of the other side of the insertion rod, the groove face of the side, far away from the small nut sleeve, of the annular groove is set to be a stop face which is used for limiting the bent ejecting sheets connected to the annular groove in a clamped mode. According to the ejecting clamping type connecting piece and the connecting pile, due to the structural arrangement of the connecting piece, an upper connecting pile body and a lower connecting pile body are fixedly connected, and the technical problem of shaking of the connection between the upper connecting pile body and the lower connecting pile body which are fixedly connected is solved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a snap-on connector and a connecting pile. Background technique [0002] During the use of pipe piles, pipe piles of different lengths need to be selected according to different usage requirements, which requires pipe piles to be connected to each other to form a longer length of pile body. At present, both ends of the existing pipe piles are provided with steel plates, and the pipe piles are connected by mutual welding. After the connected pile body is pressed into the ground when the pile is pressed, because the soil contains salt, especially chlorine salt, it will corrode the steel plate exposed to the soil, causing the joint between the pipe pile and the pipe pile to break, thus This makes the connection between the pipe piles disconnected. In addition, the way of connecting through the welding of steel plates is relatively complicated and the connection is ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned solution improves the existing technology to a certain extent, but in this solution, when connecting the pipe piles, there is a gap between the two pipe piles, so that during the use of the pipe piles, there will be shaking between the two pipe piles. In turn, it will affect the connection strength between the two pipe piles, resulting in unqualified products
