In order to solve the technical problems, the utility model provides the anti-pulling and anti-pressing connecting joint for the precast pile, which has the advantages of simple structure and low cost, can ensure the connection of the precast pile to be convenient and ensure the pile forming quality.
The technical scheme adopted by the utility model is as follows: a prefabricated pile resistance to plucking resistance to compression joint, including upper sleeve, link and lower sleeve; the upper sleeve and the lower sleeve are tubular structures, the upper sleeve is fixedly connected with the upper part of the connecting piece, and the side wall of the lower part of the connecting piece is provided with a plurality of resilience deformation joints which are arranged along the axis in a square manner; the bottom of the connecting piece is provided with a clamping hook; the inner hole of the lower sleeve is a stepped hole, and the diameter of the middle part of the inner hole is larger than that of the upper end of the inner hole; the outer diameter of the clamping hook is larger than the diameter of the upper end of the inner hole of the lower sleeve, and the clamping hook can be hooked on the step surface of the inner hole of the lower sleeve to realize the connection of the upper sleeve and the lower sleeve.
In the precast pile anti-pulling and anti-compression connecting joint, the upper sleeve is in threaded connection with the upper part of the connecting piece; the plurality of rebound deformation joints on the side wall of the lower part of the connecting piece are evenly distributed along the circumference square.
In the anti-pulling and anti-compression connecting joint for the precast pile, the cross section of the clamping hook is wedge-shaped, the excircle at the bottom of the clamping hook is smaller than the excircle at the top of the clamping hook, and the top of the clamping hook and the side wall at the lower part of the connecting piece form a step surface.
Compared with the prior art, the utility model has the beneficial effects that: the utility model has simple structure, can quickly realize the connection of the precast pile by only connecting the upper sleeve with the lower end of the steel bar of the upper precast pile, connecting the lower sleeve with the upper end of the steel bar of the lower precast pile and connecting the upper sleeve with the lower sleeve by the connecting piece, has convenient operation, high production efficiency and reliable connection, does not need welding and can ensure the pile forming quality.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1-2, the present invention comprises an upper sleeve 1, a connecting member 2 and a lower sleeve 3; the upper sleeve 1 and the lower sleeve 3 are tubular structures.
The connecting piece 2 comprises a tubular or cylindrical threaded part 21, and the upper sleeve 1 is in threaded connection with the upper part of the connecting piece 2. The lower side wall of the connecting piece 2 is provided with a plurality of elastic deformation joints 24 which are arranged along the axis in a square shape. The bottom of the connecting piece 2 is provided with a hook 22; the cross section of the clamping hook 22 is wedge-shaped, the excircle of the bottom of the clamping hook is smaller than that of the top of the clamping hook, and the top of the clamping hook and the side wall of the lower part of the connecting piece form a step surface. The inner hole of the lower sleeve 3 is a stepped hole, and the diameter of the middle part of the inner hole is larger than that of the upper end; the external diameter of pothook 22 is greater than the diameter of lower sleeve hole upper end, and pothook 22 can hook in the step face 31 department of lower sleeve hole, realizes upper sleeve 1 and the connection of lower sleeve 3.
As shown in FIG. 3, when the utility model is assembled, the upper sleeve 1 is screwed with the connecting piece 2; then, the lower part of the connecting piece 2 is aligned to the central hole of the lower sleeve 3, the clamping hook 22 is pressed into the central hole of the lower sleeve 3, the clamping hook 22 contracts towards the center due to the fact that the side wall of the lower part of the connecting piece 2 is provided with the plurality of rebound deformation joints 24 which are arranged along the axis in a square mode, when the clamping hook 22 reaches the step surface 31, the clamping hook 22 rebounds and is clamped at the step surface 31, and connection of the upper sleeve 1 and the lower sleeve 3 is achieved.
The utility model aims to replace the traditional welding and other connection modes, as shown in figure 4, an upper sleeve 1 and a lower sleeve 3 are respectively connected with steel bars 41 of two precast piles 4, the precast piles are positioned and connected in the manufacturing process, steel fittings for connection are processed in factories, the upper precast pile is connected on site, and then the upper precast pile and the lower precast pile are centered in the vacant sites, so that the upper precast pile and the lower precast pile are firmly fixed, and force transmission, pressure resistance and pulling resistance are realized. High efficiency, no need of end plates, and solves the problems of the prior construction quality, environmental pollution and the like. All the connecting components are produced in advance, the quality is guaranteed, the generated environmental pollution is less, after the connecting components are produced and reach the standard strength, the qualified products are firstly inspected, and after the connecting components are qualified, the connecting components are transported to a construction site in batches for on-site connection construction.
