Description

Technical Field

[0001] The utility model belongs to the technical field of concrete piles, and more specifically relates to a solid square pile with a hollow end plate. Background Art

[0002] Metal end plates are generally set at both ends of concrete piles. The main functions of the metal end plates are two: one is the anchoring effect when prestressed steel bars are tensioned, and the other is to weld the two metal end plates together when the piles are connected. Generally, hollow end plates are set at both ends of hollow square piles, and solid end plates are set on solid square piles. However, there are also solid square piles that use hollow end plates. For example, the existing patent with publication number CN202610797U discloses a prestressed solid concrete precast pile, in which a metal end plate with a circular / square hollow in the middle is set on the end face of the solid concrete pile body, and the metal end plate is connected to the steel cage inside the pile body.

[0003] Among them, when using hollow end plates, a number of auxiliary steel bars will be arranged in the pile body, and the cross-sections of the positions of the auxiliary steel bars correspond to the hollows on the end plates, and these auxiliary steel bars are placed in the pile body in a single form. When the pile body is poured with concrete, support plates are arranged in the hollows of the end plates at both ends in the pile body mold. The shape of the support plates is adapted to the hollows. The support plates are placed in the hollows, and the ends of the auxiliary steel bars are passed through the support plates. The ends of the auxiliary steel bars can be supported by the support plates. After the concrete is poured and initially solidified, the support plates are removed, and after the pile body is completely solidified, the excess auxiliary steel bar segments extending out of the end faces of the pile body are cut off.

[0004] Obviously, the above method has the problem of requiring cutting of auxiliary steel bars, which affects production efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a solid square pile with a hollow end plate, in which a mounting structure for the ends of the auxiliary steel bars is arranged in a body provided with auxiliary steel bars to prevent the ends of the auxiliary steel bars from extending out of the end face of the pile body. There is no need to cut the auxiliary steel bars at a later stage, thereby improving production efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a solid square pile with a hollow end plate, comprising a pile body, a hollow end plate and a plurality of auxiliary steel bars, a plurality of mounting structures are arranged on the side of the hollow end plate in contact with the pile body, the mounting structures are connected to the ends of the auxiliary steel bars, the mounting structures include a mounting plate, one end of the mounting plate is connected to the hollow end plate, the other end of the mounting plate is provided with a hanging ring, the other end of the mounting plate extends to the hollow part of the hollow end plate, so that the hanging ring is located in the hollow part.

[0007] Furthermore, a fastening bolt is provided between the mounting plate and the hollow end plate, and the fastening bolt passes through the mounting plate and is threadedly connected to the hollow end plate.

[0008] Furthermore, a gasket is provided between the fastening bolt and the mounting plate.

[0009] Furthermore, a waist-shaped hole is provided on the mounting plate, and the fastening bolt passes through the waist-shaped hole.

[0010] Furthermore, a baffle is provided on the side of the hanging ring away from the end surface of the pile body.

[0011] Furthermore, a plurality of hanging rings are arranged on the mounting plate, and connecting strips are arranged between the plurality of hanging rings.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when placing auxiliary steel bars in the mold, they can be positioned and supported by hanging rings. After the concrete is poured, the ends of the auxiliary steel bars can be kept from exposing the end faces of the pile body. There is no need to cut the auxiliary steel bars at a later stage, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
