Abstract
The utility model relates to a prestressed concrete polygonal solid or hollow pile which comprises a concrete pile body and a prestressed reinforcement which is arranged in the pile body along the length direction of the pile, wherein steel end plates which are connected with the prestressed reinforcement are arranged at two ends. The utility model is characterized in that the shape of the cross section of the pile body is a solid regular polygon or a regular polygon with hollow holes, and the shape of each steel end plate is a regular polygon which is identical with the shape of the cross section of the pile body. The utility model overcomes the defects of small compactness and low strength existing in the current pile body, effectively improves the bearing capacity, the shear resistance and pressure resistance and crack resistance in the process of construction, and has obvious advantages of saving the energy, protecting the environment, saving the materials, reducing the cost, increasing the concrete strength of the pile body and improving the work efficiency.
Description
Technical field
The utility model relates to the foundation construction technical field in the construction work, the solid or hollow pile of especially a kind of prestressed concrete polygonal.
Background technology
The present prestressed concrete pile of extensive use in the construction work, ubiquity bearing capacity and anti-shearing force are low, the resistance to compression cracking resistance is poor, and problem such as wastage of material is serious.
In addition, the two ends of a concrete pile all need the steel end plate, and the major function of steel end plate has two: the anchorage effect when being prestressed reinforcement of tensioning, another is welding is played in stake when connecting on the structure effect.So present steel end plate causes waste because of being that monoblock consumes great deal of steel.
The utility model content
The purpose of this utility model provides the solid or hollow pile of a kind of prestressed concrete polygonal, to satisfy demands of applications in the construction work, overcomes the deficiency that above-mentioned prior art exists.
Solid or the hollow pile of this prestressed concrete polygonal, constitute by the concrete pile body and along the prestressed reinforcement that is arranged in the pile body of length direction of stake, there is the steel end plate that is connected with prestressed reinforcement at two ends, the shape of cross section that it is characterized in that pile body is solid or the regular polygon of hollow hole is arranged that the profile of steel end plate is the regular polygon identical with the pile body shape of cross section.
The shape of cross section of above-mentioned regular polygon pile body is square, regular hexagon, octagon or inequilateral octagon or the like.
Hollow hole on the above-mentioned regular polygon pile body is formed by being positioned at RC hollow hole of pile body cross section or a plurality of hollow holes that are evenly distributed on the pile body cross section.Said a plurality of hollow hole can be 2～10.There are a garden shape through hole or one and the identical shaped polygon through hole of steel end plate profile in the center of above-mentioned steel end plate.
The utility model has overcome the defective that compactness is little, intensity is low that existing pile body exists, and has effectively improved bearing capacity, anti-shearing force and construction resistance to compression cracking resistance.And have energy-conserving and environment-protective, economical with materials, reduce cost, strengthen concrete strength of pile, the remarkable advantage of increasing work efficiency.
