Embodiment Construction
[0030] The following is attached Figure 1-2 The application is described in further detail.
[0031] A mechanical connection structure for uplift piles disclosed in the embodiments of the present application. refer to figure 1 and figure 2 The connection structure of the prefabricated pile 8 includes an end plate 2 and a connecting pin 1. The end plate 2 is set as a square shape consistent with the shape of the end of the prefabricated pile 8, and the four corners of the end plate 2 are provided with transition arcs to reduce stress. The end plate 2 is provided with a communication hole 6 corresponding to the hollow of the prefabricated pile 8 , and the communication hole 6 is circular to further reduce the stress on the end plate 2 .
[0032] refer to figure 1 , the end plate 2 is provided with four reinforcement holes 7, and the four reinforcement holes 7 are equally divided around the communication hole 6. The anchor reinforcement on the prefabricated pile 8 can be an...

The invention relates to the field of precast piles, and discloses a mechanical connecting structure for an uplift pile. The mechanical connecting structure comprises a connecting pin and end plates arranged at the two ends of a precast pile, the edge of each end plate is provided with a connecting groove, each connecting groove comprises an upper groove and a lower groove, the upper grooves are close to a pile body, each upper groove communicates with the corresponding lower groove, the size of the upper grooves are larger than that of the lower grooves, and the connecting pin comprises two upper parts and a middle part; and when the two precast piles are connected and aligned, the two end plates are attached, at the moment, the two upper portions of the connecting pin are embedded in the upper grooves of the two end plates correspondingly, and the middle of the connecting pin is located in the lower grooves of the two end plates at the same time. The mechanical connecting structure has the advantages that the two precast piles are rapidly and stably connected; and 2, the larger the separation trend of the precast piles is, the larger the deformation degree of the upper part of the connecting pin is, so that the locking force is larger, and the effect of stably connecting the two precast piles can be achieved.
Description
technical field [0001] The present application relates to the field of uplift-resistant prefabricated piles, in particular to a mechanical connection structure for uplift-resistant piles. Background technique [0002] At present, reinforced concrete prefabricated piles are prefabricated in prefabricated component processing plants, after curing, after reaching the design strength, they are transported to the construction site, driven into the soil with a pile driver, and then the foundation of the cap beam (slab) is poured on the top of the pile. . [0003] The Chinese patent whose notification number is CN100436722C discloses a prestressed high-strength concrete square pile. Square end plates are arranged at both ends of the square pile. Bevels are arranged on the four sides of the end plate. Threading holes; the stirrups of the reinforcement cage are welded continuously to the main reinforcement in a spiral shape, and the main reinforcement is steel strand or steel rod; t...
