Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of structural connectors between square pile reinforcement and foundation reinforcement, specifically a simple, reliable, low-cost, and quick-connecting connector between square pile reinforcement and foundation reinforcement. Background Technology
[0002] As is well known, existing square piles are used as foundation piles by being hammered into the ground. When the exposed height of the square pile reaches the required height, the reinforcing steel of the square pile is connected to the reinforcing steel of the pile cap. However, after the square pile is hammered into the ground, there is still a certain height of exposed upper part of the square pile. At this time, it is necessary to break the concrete at the upper part of the square pile, cut off the excess square pile reinforcing steel, and retain the square pile and square pile reinforcing steel at the set exposed ground height. Then, the square pile reinforcing steel is connected to the pile cap reinforcing steel through a connector. The existing square pile reinforcing steel and pile cap reinforcing steel are connected by welding, which has low connection stability. The existing threaded connector connection structure also requires the outer periphery of the pile cap reinforcing steel or square pile reinforcing steel to be machined with threads, which makes the installation process cumbersome and slow. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a simple, reliable, low-cost, and quick-connecting connector for square pile reinforcement and foundation reinforcement.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A connector for square pile reinforcement and foundation reinforcement, comprising square pile reinforcement and foundation reinforcement, characterized in that the square pile reinforcement and foundation reinforcement are connected by a connector assembly, the connector assembly including a connecting sleeve, a retaining spring, a spring, and a compression nut. The connecting sleeve has a square pile reinforcement insertion hole and a foundation reinforcement insertion hole. The square pile reinforcement insertion hole is a frustum-shaped hole, with the smaller end of the frustum-shaped hole located on the outside of the connecting sleeve, and the larger end of the frustum-shaped hole communicating with the foundation reinforcement insertion hole. A retaining spring is provided inside the square pile reinforcement insertion hole. The spring consists of at least three cone-shaped clips. The spring is placed inside the insertion hole of the foundation reinforcement. The end of the spring contacts the clip. The connecting sleeve outside the insertion hole of the foundation reinforcement has external threads. The connecting sleeve has a compression nut that mates with the external threads. The upper end of the compression nut has a compression sealing plate, which is integrally connected with the compression nut. The compression sealing plate has a through hole for the foundation reinforcement. The lower end of the foundation reinforcement has a snap-fit head, which snaps onto the compression sealing plate and is locked onto the connecting sleeve by the compression nut.
[0006] The height of the pier head of the foundation reinforcement described in this utility model is greater than the distance between the spring after compression and the end face of the connecting sleeve, ensuring that the compression sealing plate on the compression nut is always tightly pressed against the pier head of the foundation reinforcement.
[0007] The sleeve nut of this utility model has a vertical insertion hole on its side, which is connected to the insertion hole of the foundation reinforcement and the through hole of the foundation reinforcement. The width of the vertical insertion hole is not less than the diameter of the foundation reinforcement, which facilitates the lateral insertion of the pier head reinforcement.
[0008] The sleeve nut of this utility model has a T-shaped insertion hole on its side. The T-shaped insertion hole is connected to the insertion hole of the foundation reinforcement and the through hole of the foundation reinforcement. The T-shaped insertion hole is for the side of the foundation reinforcement with the pier head to be inserted.
[0009] This utility model, due to the above-mentioned structure, has the advantages of simple structure, reliable quality, low cost, and quick connection. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings:
[0015] As shown in the attached figure, a connector for square pile reinforcement and foundation reinforcement includes square pile reinforcement 1 and foundation reinforcement 2. The square pile reinforcement 1 and foundation reinforcement 2 are connected by a connector assembly 3. The connector assembly 3 includes a connecting sleeve 4, a retaining spring 5, a spring 6, and a compression nut 7. The connecting sleeve 4 has a square pile reinforcement insertion hole 8 and a foundation reinforcement insertion hole 9. The square pile reinforcement insertion hole 8 is a frustum-shaped hole, with the smaller end of the frustum-shaped hole located on the outside of the connecting sleeve 4, and the larger end of the frustum-shaped hole communicating with the foundation reinforcement insertion hole 9. A retaining spring 5 is provided inside the square pile reinforcement insertion hole 8. It consists of at least three cone-shaped cards. A spring 6 is placed inside the insertion hole 9 of the foundation steel bar. The end of the spring 6 contacts the retaining ring 5. The connecting sleeve 4 outside the insertion hole 9 of the foundation steel bar is provided with external threads. The connecting sleeve 4 is provided with a compression nut 7 that mates with the external threads. The upper end of the compression nut 7 is provided with a compression sealing plate 10. The compression sealing plate 10 is integrally connected with the compression nut 7. The compression sealing plate 10 is provided with a through hole 11 for the foundation steel bar. The lower end of the foundation steel bar 2 is provided with a snap-fit head 12. The snap-fit head 12 of the lower end of the foundation steel bar 2 is snapped on the compression sealing plate 10 and locked on the connecting sleeve 4 by the compression nut 7.
[0016] Furthermore, the height of the pier head of the foundation steel bar 2 is greater than the distance between the spring 6 after compression and the end face of the connecting sleeve 4, ensuring that the sleeve sealing plate 10 on the sleeve nut 7 is always tightly pressed against the pier head of the foundation steel bar 2.
[0017] Furthermore, the side of the compression nut 7 is provided with a vertical insertion hole 13, which is connected to the foundation reinforcement insertion hole 9 and the foundation reinforcement through hole 11. The width of the vertical insertion hole 13 is not less than the diameter of the foundation reinforcement 2, which facilitates the lateral insertion of the pier head reinforcement.
[0018] Furthermore, the side of the compression nut 7 is provided with a T-shaped insertion hole 14, which is connected to the foundation reinforcement insertion hole 9 and the foundation reinforcement through hole 11. The T-shaped insertion hole 14 is for the side of the foundation reinforcement 2 with the pier head to be inserted.
[0019] When the exposed ground height of the square pile after being hammered is higher than a set height, the concrete at the top of the square pile needs to be broken up, and the excess square pile reinforcement 1 needs to be cut off, retaining the square pile and square pile reinforcement 1 at the set exposed ground height. Then, the square pile reinforcement 1 is connected to the foundation reinforcement 2 through a connector. The specific connection method is as follows: First, the end of the foundation reinforcement 2 is vertically made into a foundation reinforcement 2 with a pierced head. The height of the pierced head of the foundation reinforcement 2 is greater than the distance between the spring 6 after compression and the end face of the connecting sleeve 4. Then, the side of the foundation reinforcement 2 with the pierced head is inserted into the compression nut 7. Then, the square pile reinforcement 1 is inserted into the square pile reinforcement insertion hole 8 of the connecting sleeve 4. The clips are respectively clamped in the circumferential direction of the square pile reinforcement 1. The spring 6 is placed on top of the clips and the connecting through hole is pulled upwards. Under the action of the square pile reinforcement insertion hole 8 and the clip 5, the square pile reinforcement 1 is tightly clamped into the connecting sleeve 4. Then, the installation is completed. The compression nut 7 of the pile cap steel bar 2 with the pier head is fitted onto the outside of the connecting sleeve 4. Rotating the compression nut 7 tightly presses the pile cap steel bar 2 onto the connecting sleeve 4. The spring 6 pushes the pile cap steel bar 2 upwards and presses the retaining spring 5 downwards. Therefore, the stability of the square pile steel bar 1 and the pier head steel bar after connection is very high, and the installation is fast. When processing the connecting sleeve 4, only the square pile steel bar insertion hole 8 and the pile cap steel bar insertion hole 9 need to be opened. The outer wall of the connecting sleeve 4 is processed with external threads, and the inner wall does not need to be threaded, which saves costs. Moreover, the mechanism of the compression nut 7 can better press the pile cap steel bar 2 tightly onto the connecting sleeve 4, which increases the stability of the connection. The pile cap steel bar 2 only needs to be pierced, and there is no need to tap it. Therefore, the overall processing cost is low and the installation speed is fast. Due to the above structure, this utility model has the advantages of simple structure, reliable quality, low cost and fast connection.
