Description

Technical Field

[0001] This utility model belongs to the field of prestressed pipe pile technology, and relates to pile heads suitable for non-welded connections. Background Technology

[0002] Prestressed concrete piles are commonly used in engineering projects, especially in many new energy photovoltaic projects, such as the transformer substation foundations and electrical primary and secondary equipment foundations of floating photovoltaic projects. During construction, when multiple piles for the same equipment are designed to have the same pile top elevation, the pile top elevation error is large due to on-site pile driving, causing problems with the connection between the superstructure and the piles. At the same time, the project site may be affected by limitations such as construction power supply and weather conditions, making it impossible to adjust the pile top elevation by welding. In this case, it is of great significance to find a more convenient pile top connection joint that is also applicable to different pile top elevations and reduces the construction period. Utility Model Content

The pile head is composed of two symmetrical half pile heads, which are connected by external hexagonal bolts. A gap is set between the two half pile heads. Each half pile head includes a top plate, a vertical connecting plate, and a vertical arc plate.

[0005] It also includes prestressed pipe piles, with the pile head fitted onto the outer wall of one end of the prestressed pipe pile.

The two vertical connecting plates are connected together to the vertical curved plate, which is also connected to the top plate. A vertical stiffening plate is connected between the top plate and the vertical curved plate.

[0009] The outer contour of the top plate is a regular polygon. The center of the circumcircle of the top plate coincides with the center of the vertical arc plate. The diameter of the circumcircle of the top plate is greater than the outer diameter of the vertical arc plate, and the inner diameter of the vertical arc plate is equal to the diameter of the circular cavity in the middle of the pile head.

[0010] The diameter of the outer circle of the pile head is 400~600cm, and the diameter of the vertical arc plate is 200~400cm.

[0011] External hex bolts are installed on the vertical connecting plates, and the two adjacent vertical connecting plates on the two half-pile heads are connected by matching external hex bolts.

[0012] The vertical connecting plate and the vertical curved plate have the same length, both 200~250cm. The width of the vertical connecting plate is 90~100cm, and the thickness of the vertical curved plate is 10~15cm.

[0013] The vertical connecting plate, vertical curved plate, vertical stiffening plate, and top plate are all made of steel.
