Description

Technical Field

[0001] The utility model belongs to the technical field of concrete square piles, and more specifically relates to a solid square pile without end plates. Background Art

[0002] Generally, metal end plates are provided on both end surfaces of a solid square pile. The end plates are used to connect two square piles to make the sides of the two short square piles longer, thereby meeting the installation requirements. The connection between the two square piles is achieved by welding the two opposite end plates, but the rear end plates will still be exposed after welding. After the square piles are buried underground, the end plates are easily corroded, which affects the connection strength between the two square piles.

[0003] The patent technology with publication number CN108824420A discloses a solid square pile connection sleeve without end plates, in which connection sleeves are arranged at both ends of the square pile. When two square piles are connected, an anchor steel bar is used to thread the connection sleeves on the end faces of the two square piles, thereby realizing the connection of the two square piles.

[0004] However, according to common sense, after the anchor steel bar is first connected to the connecting sleeve of one of the square piles, it cannot be threadedly connected to the connecting sleeve of the other square pile. If two opposite sections of threads (left-hand and right-hand threads) are used at both ends of the anchor steel bar, the end faces of the two square piles cannot be brought into contact with each other during connection. Therefore, it is impossible to connect two square piles using the threaded connection method of the anchor steel bar, and the technical solution is unclear. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a solid square pile without end plates, which has a good connection effect and is not afraid of corrosion.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a solid square pile without end plates, wherein T-shaped ring grooves are arranged on both end faces of the square pile, an opening is arranged on one side of the T-shaped ring groove, and the opening is connected to the T-shaped ring groove and the side face of the square pile, and after the end faces of two adjacent square piles are fitted together, the two T-shaped ring grooves form an "I"-shaped ring groove, and the two openings correspond to each other to form an entrance, and a plurality of "I"-shaped connecting blocks are arranged in the "I"-shaped ring groove.

[0007] Furthermore, a stopper is filled in the T-shaped ring groove on one side of the opening, and the stopper is integrated with the square pile.

[0008] Furthermore, the cross section of the “I”-shaped connecting block is fan-shaped and matches with the “I”-shaped ring groove.

[0009] Furthermore, a blocking block is arranged in the inlet, and one side of the blocking block is in contact with an “I”-shaped connecting block placed in an “I”-shaped ring groove at the corresponding inlet.

[0010] Furthermore, a positioning rod is provided on one end surface of the square pile, and a positioning hole is provided on the other end surface.

[0011] Furthermore, a metal piece having a T-shaped ring groove is embedded in the T-shaped ring groove, so that the inner wall of the T-shaped ring groove is smoother.

[0012] Compared with the prior art, the utility model has the following beneficial effects: after the end faces of the two square piles are in contact, the two openings are aligned, and then the "I"-shaped connecting block is placed from the entrance into the "I"-shaped ring groove, and then one of the square piles is rotated, and the "I"-shaped connecting block is rotated and pushed into the interior of the "I"-shaped ring groove through the block on one side of the square pile opening, and then the other "I"-shaped connecting blocks are placed in the "I"-shaped ring groove in turn, until the last "I"-shaped connecting block is directly placed at the position corresponding to the "I"-shaped ring groove and the entrance, and then the entrance is blocked with a blocking block, thereby realizing the connection of the two square piles through a number of "I"-shaped connecting blocks, without metal end plates, with good connection effect and no fear of corrosion.
