Description

Technical Field

[0001] The utility model relates to the technical field of building pile foundation engineering, in particular to a pile top and cap connection piece provided with a stable clip. Background Art

[0002] In the existing connection method between the pile top and the pedestal of the precast concrete pile, ordinary steel bars are processed through various processes. The ordinary steel bars need to be preheated and burned red, extruded into shape by a mold, and then made into thread patterns. The entire connecting piece is complicated to process and the cost is high. In addition, the existing connecting piece has poor tensile strength after installation. Therefore, in view of the above problems, a pile top and pedestal connecting piece with a stable clip is designed to better meet the actual use needs. Utility Model Content

[0003] The utility model aims to provide a pile top and cap connection piece provided with a stable clip, so as to solve the problems of complex processing, high cost and poor pull-out resistance of the connection piece proposed in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pile top and pedestal connector provided with a stabilizing clip, comprising a prestressed tendon, on which a stabilizing clip body is installed, the stabilizing clip body is installed in cooperation with a stabilizing nut, and the stabilizing nut is arranged on the outside of the prestressed tendon.

[0005] Preferably, a rough head is provided at the lower end of the prestressed tendon, and the diameter of the rough head is larger than the diameter of the inner hole of the stabilizing clip body. Through the action of the rough head, the position of the prestressed tendon and the stabilizing clip body can be conveniently limited to ensure the stability of the connector assembly.

[0006] Preferably, the stabilizing clip body and the prestressed tendon are connected by a sleeve connection, and the cross-section of the stabilizing clip body is a trapezoidal structure, and the opening of the stabilizing clip body is a C-shaped arc structure. The trapezoidal cross-sectional structure of the stabilizing clip body can provide basic guarantee for the positioning and installation of the stabilizing clip body.

[0007] Preferably, anti-skid teeth are provided inside the stabilizing clip body, and the anti-skid teeth are in contact with the prestressed tendons to achieve an anti-skid effect. Friction is generated by the contact between the anti-skid teeth and the prestressed tendons, thereby ensuring the stability of the connection between the stabilizing clip body and the prestressed tendons.

[0008] Preferably, an external thread is provided on the outer side of the stabilizing nut, and a card slot is provided on the stabilizing nut. The stabilizing nut is also provided with an installation groove with a trapezoidal cross-section, and the installation groove and the stabilizing clip body are nested and connected. Through the action of the installation groove, the clamping effect of the stabilizing clip body can be achieved, thereby ensuring the anti-pullout effect of the entire connecting piece.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the pile top and base connecting piece provided with a stabilizing clip adopts a combined installation structure, which can facilitate the mass production and later installation of the entire connecting piece, thereby greatly reducing the difficulty of production and effectively saving production costs, and the entire assembly is simple to install, which greatly reduces the difficulty of construction, and after installation, the trapezoidal structure of the stabilizing clip body cooperates with the installation groove on the stabilizing nut, which can greatly improve the pull-out resistance of the connecting piece, and is more stable and reliable than the traditional cylindrical structure.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-Figure 3 The utility model provides a technical solution: a pile top and a cap connection piece provided with a stabilizing clip, comprising a prestressed tendon 1, a stabilizing clip body 2 is installed on the prestressed tendon 1, the stabilizing clip body 2 is installed in cooperation with a stabilizing nut 4, and the stabilizing nut 4 is arranged on the outside of the prestressed tendon 1.

[0016] A thick head 101 is provided at the lower end of the prestressed tendon 1, and the diameter of the thick head 101 is larger than the inner hole diameter of the stabilizing clip body 2; the stabilizing clip body 2 and the prestressed tendon 1 are sleeve-connected, and the cross-section of the stabilizing clip body 2 is a trapezoidal structure, and the opening of the stabilizing clip body is a C-shaped arc structure; anti-skid teeth 3 are provided on the inner side of the stabilizing clip body 2, and the anti-skid teeth 3 are in contact with the prestressed tendon 1 to achieve an anti-skid effect; an external thread 401 is provided on the outer side of the stabilizing nut 4, and a card slot 402 is provided on the stabilizing nut 4, and a mounting groove 403 with a trapezoidal cross-section is also provided on the stabilizing nut 4, and the mounting groove 403 and the stabilizing clip body 2 are nested.

[0017] When using the pile top and cap connection member provided with a stabilizing clip, if Figure 1-Figure 3 As shown, first assemble the entire connector, first (put an open C-shaped arc-shaped stabilizing clip from the thick end of the prestressed tendon 1 into the thick end 101 of the prestressed tendon 1) or design it as a circular whole with two arc-shaped structures according to actual construction needs, and use rubber bands or straps to combine the two semicircular stabilizing clip bodies 2 into a circular whole and bind them to the prestressed tendon 1, and at this time, the lower end of the stabilizing clip body 2 is in contact with the thick end 101, and then the prestressed tendon 1 is installed in coordination with the opening on the top of the pile, and the stabilizing nut 4 is sleeved on the prestressed tendon 1, so that the stabilizing nut 4 passes through the outer thread. The groove 401 is assembled with the opening on the pile top and is tightened by engaging the slot 402 with a wrench. At this time, the stabilizing nut 4 and the stabilizing clip body 2 are just nested and assembled until the stabilizing nut 4 and the pile top are assembled, thereby realizing the installation of the entire connecting piece. In actual use, when the connecting piece is subjected to tension, the stabilizing nut 4 can be used to wrap and hold the stabilizing clip body 2, thereby realizing the anchoring effect, effectively ensuring the pull-out resistance of the entire connecting piece, thereby ensuring the stability of the connection between the pile top and the base. This is the working principle of the pile top and base connection piece with a stabilizing clip.
