Abstract
Pretensioning steel strand wire concrete tubular pile consists of annular tubular concrete pile body and end plate. Inside the tubular concrete pile body there equips steel bar framework. The prestressing force main reinforcement in the steel bar framework is steel strand wire, whose end crosses the stretching hole at the end to produce anchor. The screwy reinforcement helically encircles to fix prestressing force main reinforcement and set-up reinforcement as a whole. Because the quality of steel strand wire material is steady, it can not only insure the quality of the high strength prestressing force concrete tubular pile, but also the pile is provided with the advantages of high material strength, strong prestressing force, high bending strength and good carrying capability.
Description
Technical field
The invention belongs to the pile foundation Foundation Design technology in the building field, is a kind of prestressed concrete pipe pile with pretensioning type strands.
Background technology
Building foundation engineering is the foundation of building, pile foundation become the structure building various buildings, particularly highrise building, heavy factory building in the bad area of soil property and have specific (special) requirements the base form that extensively adopts.The quality of stake directly influences the quality of pile foundation, because pile foundation quality is nonconforming, it is non-rare to cause brewageing major accident.At present, China coastal cities, buildings such as construction industry factory building, civilian construction and bridge, power station, harbour, warehouse are used most often prestressed concrete pipe pile.Existing Pretensioned spun concrete piles, its main muscle all adopts rod iron to make, because the rod iron quality of materials is stable inadequately, be easy to generate the brittle failure phenomenon, moreover rod iron adopts the anchoring of heading technology, and heading technology affects greatly the rod iron performance, the rod iron mechanical performance index will be reduced, the construction quality and the application life of building can be had a strong impact on like this.The skeleton master muscle that also has a kind of prestressed concrete pipe pile is to substitute traditional rod iron with steel wire, though it can save a large amount of steel and concrete, but its intensity is not reach quality requirement far away, and it can cause and stay serious accident potential to building operations.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art and defective, for building trade provides a kind of prestressed concrete pipe pile with pretensioning type strands.
The technical solution used in the present invention is for achieving the above object: this prestressed concrete pipe pile with pretensioning type strands is made up of annular tube shaped concrete pile body and end plate, tubular coagulation soil pile body is built-in with cage of reinforcement, the prestressing force master muscle of this cage of reinforcement is a steel hinge line, and its end is passed the stretchable holes that is arranged on the end plate and made prestressed anchor; Be provided with bearing rod at described prestressing force master muscle side; Spiral bar with helical form around prestressing force master muscle and bearing rod are interconnected into cage of reinforcement.
Prestressing force master muscle of the present invention substitutes traditional rod iron with steel hinge line, because the quality of materials of steel hinge line is stable and intensity is high, not only can guarantee the quality of high strength prestressed concrete pipe pile, and this stake has strength of materials height, prestressing force is big, and flexural strength is big, the characteristics that bearing capacity is strong.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is that the B of Fig. 1 is to view.
The specific embodiment
As shown in the figure, this steel hinge line prestressed concrete pipe pile is made up of annular tube shaped concrete pile body 6 and end plate 5.End plate 5 is covered in the end of pile body 6.The pile body of concrete tubular pile is built-in with cage of reinforcement, and the prestressing force master muscle 1 of this cage of reinforcement is a steel hinge line, and prestressing force master muscle is uniform arrangement; Its side can be provided with bearing rod 2 according to the structure needs, with spiral bar 3 with helical form around an integral body that each prestressing force master muscle 1, bearing rod 2 is fixedly connected into cage of reinforcement.End plate 5 is provided with stretchable holes, and prestressing force master muscle passes this stretchable holes and makes prestressed anchor 4.Pour concrete on cage of reinforcement earlier during manufacturing, matched moulds carries out the stretch-draw of prestressing force master muscle then, by centrifugal, the steam-cured tubulose prestressed concrete pipe pile of promptly making.
