Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped prefabricated piles, in particular to an integrally formed special-shaped prefabricated pile end plate. Background Art

[0002] During the construction of special-shaped prefabricated piles, due to the special shape of their end faces, the end hoop plates cannot be set synchronously with the end plates during construction. Instead, hoop plates are set around the outer surface of the pile head after forming, and the joints of the hoop plates are further welded. At the same time, the contact parts of the hoop plates and the end plates are connected by welding, or the hoop plates are not set directly.

[0003] Since the end hoops are not set synchronously during the prefabrication, only the end face of the pile head is under pressure during the prefabrication process, which results in uneven stress distribution in the pile head. Therefore, when the pile head is hammered into the foundation in the subsequent construction, the pile head will be damaged due to force deviation during the hammering process due to the uneven stress distribution in the construction process. Further, the end hoops are set after the forming process, which makes the connection between the end hoops and the pile head less tight, that is, the protective effect on the pile head is poor, and the protective effect is not obvious. There is also a risk of pile head damage when the pile head is hammered into the foundation. This is why some special-shaped prefabricated piles are not directly equipped with hoops.

[0004] Based on the above situation, we proposed an integrally formed special-shaped prefabricated pile end plate. Utility Model Content

[0008] A plurality of steel bar pull rods are distributed at intervals on the inner side of the hoop plate, and two ends of the steel bar pull rods are respectively welded between the inner surfaces of the hoop plates in a relative state.

[0009] Preferably, the plate bodies of the hoop plate are an integrated structure, and the hoop plate is formed by stamping and extending the outer edge of the panel, that is, the hoop plate and the panel are an integrated structure.

[0010] Preferably, the plate bodies of the hoop plate are of split structure, that is, the hoop plate is formed by enclosing a plurality of split plates, the split plates and the panel are of an integral structure, and the adjacent plate edges of the enclosed split plates are welded and fixed.

[0012] Due to the functions of the face plate and the hoop plate, the end face and outer surface of the precast pile head are in a synchronously compressed state, ensuring uniform stress distribution in the pile head during the solidification and forming process of the precast pile. Furthermore, in the process of being hammered into the foundation after forming, the pile head can be ensured to be uniformly stressed, thus avoiding damage to the pile head caused by force deviation, which is conducive to the construction and use of special-shaped precast piles.
