Abstract
The utility model provides a prestressed triangular pile. A pile body is cast by using concrete, main ribs are placed in parallel in the pile body along the axial direction, a reinforcement cage woven by using the main ribs and spiral stirrups is wrapped by a concrete protective layer, the cross section of the pile body is triangular, and the main ribs are two or more prestressed main ribs. A through hole is formed in the pile body, the through hole penetrates the sections of two ends of the pile body and is coaxial with the pile body, and the section of the pile body is of a hollow triangle. The two or more prestressed main ribs are uniformly arranged around the through hole. The prestressed main ribs are arranged in a triangle and are coaxial with the pile body or the through hole. Three vertex angles of each of the pile body and the concrete protective layer are arc chamfers. An end plate is arranged at each of two ends of the pile body, a hoop is welded on each end plate, and the end plates are welded on the prestressed main ribs and the spiral stirrups. One end of the pile body is provided with a pile tip. The prestressed triangular pile is simple in structure and firm, and saves raw materials.

At present, normally used pile body is cylindric or flat column in the building field, and reinforcement cage structure is unstable, and anti-bending strength and torsional property are relatively poor, and concrete use amount is larger.
Summary of the invention
The purpose of this utility model provides a kind of prestressing force triangular pile, and is simple in structure, solid firm, saves raw material.
The technical solution of the utility model: prestressing force triangular pile; pile body is formed by pouring concrete, parallelly vertically in the pile body is placed with main muscle, in the reinforcing cage that concrete cover is woven into main muscle and spiral stirrup is wrapped in; the cross section of pile body is triangle, and main muscle is prestressing force master muscle.
Be provided with through hole in the described pile body, through hole is through the cross section at pile body two ends and coaxial with pile body, and the cross section of pile body is hollow triangle.
The number of described prestressing force master muscle is two or more, and be evenly arranged in through hole around.
The arrangement of described prestressing force master muscle is triangular in shape, and coaxial with pile body or through hole.
Three drift angles of described pile body and concrete cover are the circular arc chamfering.
The two ends of described pile body are equipped with end plate, and cuff is welded on the end plate, and end plate is welded on prestressing force master muscle and the spiral stirrup.
One end of described pile body is provided with pile top.
The beneficial effects of the utility model: because pile body adopts the triangulo column shape, and is provided with several prestressing force master muscle in the pile body, prestressing force master muscle is triangle arrangement, so that pile body is more solid firmly, reliability and durability, saved simultaneously raw material, reduced the cost of producing and using; Owing to be provided with through hole in the pile body, through hole is through the cross section at pile body two ends, and coaxial with pile body, like this so that in the situation of the same bearing capacity of assurance, saved concrete use amount; Because three drift angles of pile body and concrete cover are the circular arc chamfering, be convenient to reduce the concrete wearing and tearing of drift angle in the construction; Owing at the two ends of pile body end plate is installed, cuff is welded on the end plate, and end plate is welded on prestressing force master muscle and the spiral stirrup, makes the two ends of pile body in use not easy to crack, has guaranteed efficient and the quality of construction; Owing to be provided with pile top at an end of pile body, make that to enter bearing stratum in the construction darker, increased bearing capacity of pile.
