Abstract
The invention relates to a stretching system for a concrete tubular pile, and the stretching system comprises a tubular tile mould and a steel wire cage which is arranged inside the tubular tile mould, wherein two ends of the steel wire cage are respectively provided with a head end head plate and a tail end head plate. The stretching system for the concrete tubular pile is innovatively characterized in that an external stretching plate is fixedly arranged at the head end of the tubular tile mould and the head end head plate is connected with an internal stretching plate; a locking screw rod is fixed in the center of the stretching plate and the locking screw rod extends out of the external stretching plate to be locked together with a locking nut through screw threads. In the invention, the internal stretching plate is connected with the head end head plate, the pull force is applied to the locking screw rod by matching the locking nut with the external stretching plate, and the head end head plate is pulled to move through the internal stretching plate which is connected with the locking screw rod; the steel wire cage is uniformly stressed so that the quality of the molded tubular pile is ensured; and the stretching system has the advantages of less subassemblies and low production cost.
Description
Technical field
The present invention relates to a kind of concrete tubular pile tensioning system, the concrete tubular pile tensioning system that particularly a kind of stretch-draw is effective.
Background technology
Along with the development of concrete technology, the technology of concrete tubular pile also reaches its maturity, and except that being applied to industry, civil buildings, also is widely used in each field such as bridge, harbour, railway or hydraulic engineering.
When carrying out the production of concrete tubular pile; Need carry out prestressed stretch-draw to the wire basket in the pipe pile die; Stretching force is directly delivered on the end plate in the present tensioning system, and its unbalance stress is prone to produce eccentric; The prestressing force of wire basket PC rod is inconsistent after the moulding, and the tension of pile tube, anti-pressure ability and shear resistance all are affected.
Number of patent application 201020003653.2 discloses a kind of tubular pile pre-stress stretching device; It has gusset piece through bolt on the end plate of wire basket; And the other end of gusset piece is connected with coupling head, and the inner nut built-in through coupling head connects with tie down screw.Through inner nut and coupling head cooperation gusset piece is applied pulling force by tie down screw during stretch-draw, make stretching force evenly be delivered on the end plate, each point prestressing force basically identical, Forming Quality is better.Its shortcoming is: tie down screw is connected with end plate through coupling head, inner nut, gusset piece, and parts are many, and manufacturing cost is higher, and the pile tube that caliber is bigger is particularly evident.In addition, adopt bolt thread locking between gusset piece and the end plate, need disassemble when putting, more time-consuming, influence integral body put an efficient.
Summary of the invention
The technical problem that the present invention will solve provides the effective concrete tubular pile tensioning system of a kind of stretch-draw.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of concrete tubular pile tensioning system; Comprise pipe pile die, and be located at the wire basket in the pipe pile die, the two ends of said wire basket are respectively first end plate and tail end plate; Its innovative point is: the head end of said pipe pile die is fixed with outer stretch-draw plate; Said first end plate is connected with interior stretch-draw plate, said in stretch-draw plate center fixation one tie down screw is arranged, behind the protruding outer stretch-draw plate of said tie down screw with locking nut screw-threaded coupling.
Further; Said first end plate is connected with interior stretch-draw plate through quick detaching structure; Its concrete structure is: be connected with some interior stretch-draw crab bolts on the said first end plate; Be evenly distributed with the corresponding connecting hole of some and interior stretch-draw crab bolt on the stretch-draw plate in said; Said connecting hole is formed by being communicated with transitional pore and locking hole, and the aperture of said transitional pore is greater than the outer end diameter of interior stretch-draw crab bolt, and the aperture of said locking hole is greater than the body of rod external diameter of interior stretch-draw crab bolt and less than the outer end diameter of interior stretch-draw crab bolt.
The invention has the advantages that: interior stretch-draw plate is connected with first end plate; Adopt locking nut to cooperate tie down screw is applied pulling force with outer stretch-draw plate; Interior stretch-draw plate through being connected with tie down screw spurs first end plate, and wire basket is stressed evenly, pile tube quality after the assurance moulding; And the tensioning system assembly is few, and cost of manufacture is low.
First end plate is connected with interior stretch-draw plate through quick detaching structure; During use; Interior stretch-draw crab bolt screw-threaded coupling is on first end plate, and stretch-draw crab bolt in the transitional pore of interior stretch-draw plate is aimed at makes the end of interior stretch-draw crab bolt stretch out transitional pore; The stretch-draw crab bolt was transferred in the locking hole in the stretch-draw plate can make in rotating again, and the aperture that utilizes locking hole realizes fixing first end plate and being connected of interior stretch-draw plate greater than the body of rod external diameter of interior stretch-draw crab bolt and less than the outer end diameter of interior stretch-draw crab bolt.Only need reverse during dismounting to make first paragraph header plate and interior stretch-draw plate break away from, and need not demounting bolt, can improve and put an efficient.
