Description

Technical Field

[0001] The utility model relates to the technical field of concrete solid square piles, in particular to an anti-pullout device for concrete solid square piles. Background Art

[0002] Concrete solid square pile is a kind of prefabricated pile, and its cross section is generally square. The cross section of the pile body generally remains unchanged along the length of the pile. Its advantages are that the length and cross section can be selected within a certain range according to the actual needs of the site, and because it is prefabricated on the ground, the production quality is guaranteed.

[0003] When the lower end of the front pile is mostly a conical solid structure, when it is inserted into the foundation, it mainly relies on the gravity of the concrete solid square pile itself to prevent it from shaking. At present, the surface structure of ordinary solid square piles is relatively simple, so it is easy to tilt under the action of external force, which makes the square pile easy to loosen after installation. Therefore, an anti-pullout device for concrete solid square piles is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the outer structure of ordinary solid square piles is relatively simple, which is easy to warp under the action of external force, thereby causing the square piles to become loose after installation. The utility model provides an anti-pullout device for concrete solid square piles.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A pull-out resistant device for a concrete solid square pile comprises a square pile body, a connection mechanism is cast inside the square pile body, a connecting column is arranged on one side of the connection mechanism, a conical block is fixedly mounted on one end of the connecting column, a rotating groove is provided on the side wall of the conical block, an anti-pull-out mechanism is arranged in the rotating groove; the anti-pull-out mechanism comprises a connecting shaft, both ends of the connecting shaft are rotatably mounted in the rotating groove of the conical block, and a reverse plug plate is fixedly mounted on the connecting shaft.

[0007] Preferably, the connection mechanism comprises a support plate, a plurality of L-shaped anchor rods are fixedly mounted on one side of the support plate, and a connection tube is fixedly mounted on the other side of the support plate, and one end of the connecting column is arranged in the connection tube.

[0008] Preferably, an inner wall of the connecting pipe is provided with an internal thread, and an outer wall of the connecting column is provided with an external thread, and the connecting column is threadedly installed in the connecting pipe.

[0009] Preferably, positioning holes are provided on the side walls of the connecting tube and the connecting column, and positioning bolts are inserted and installed in the positioning holes, and a positioning nut is provided on one side of the positioning bolt.

[0010] Preferably, a plurality of the rotation grooves are provided, and the plurality of rotation grooves are annularly distributed on the side wall of the conical block. Limiting baffles are fixedly installed in the plurality of rotation grooves, and the limiting baffles are arranged on one side of the reverse insertion plate.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the square pile body and the conical block are inserted into the foundation, and then the provided reverse insertion plate will be stuck into the soil of the foundation. In this way, when the square pile body tilts upward, the provided reverse insertion plate can increase the force required for the concrete square pile to tilt due to being inserted into the formation, thereby increasing the difficulty of prying and pulling up the square pile body, increasing the stability of the concrete square pile, and reducing the probability of its loosening.
