Description

A kind of straining device of producing for pile tube

Technical field

The utility model relates to pile tube and manufactures field, more particularly, relates to a kind of straining device of producing for pile tube.

Background technology

Prestressed concrete pipe pile is widely used in the fields such as industry, civil buildings, harbour, railway, in prestressed concrete pipe pile manufacture process, need to carry out prestressed stretch-draw to the steel reinforcement cage in pipe pile die, prestressed concrete pipe pile is generally single manufacture at present, and production efficiency is lower.

In prestressed high-strength concrete pile production process, comprised a very important operation---tension process.Tension process is to adopt hydraulic jack, and by tensioning screw rod, stretch board is connected with end plate, and pulling force is delivered on longitudinal reinforcement, the prestress value of reinforcing bar is reached: 994MPa.Prestressing force reaches after numerical value, by tensioning screw rod upper locking nut, tensioning screw rod is longitudinally being locked in die face.Meanwhile, in concrete-pile, longitudinal reinforcement stress remains to concrete hardening always, is present in concrete-pile always, thereby makes prefabricated pile have higher resistance to compression, bending strength performance.

In traditional tension process, tensioning equipment is generally five covers, this tradition stretch-draw external member possesses following defect: 1, when steel reinforcement cage that lifting assembles, at stretch board and tensioning screw rod, enter in the process of mould, because traditional stretch board weight (heavier) and tensioning screw rod weight act on steel reinforcement cage end simultaneously, easily cause the steel reinforcement cage cage phenomenon of faling apart, have a strong impact on concrete-pile workmanship; 2, for stretch board and tensioning screw rod, be positioned in advance the mounting means that steel reinforcement cage (band end plate) is installed in mould, when defect is fastening bolt, muscle power expends large, steel reinforcement cage and when distortion, produces the cage that falls apart; 3, this tensioning equipment is not established special position for dismounting plate end to end, has increased the workload of plate handling process end to end, makes production efficiency and security step-down, the waste working time.

In addition, prestressed concrete pipe pile is generally single manufacture at present, and production efficiency is lower.

Through retrieval, have for the tensioning equipment in pile tube production process in prior art and carry out improved technical scheme openly, Chinese Patent Application No. 201210163499.9, the application day for announcing is on September 19th, 2012, invention and created name is: the tension tool of simultaneously manufacturing many prestressed concrete pipe piles, this application case relates to a kind of tension tool of simultaneously manufacturing many prestressed concrete pipe piles, comprise the fixed head and the latch that are located at respectively pipe pile die two ends, described latch is provided with the tensioning screw rod that stretch-draw is used, described tensioning screw rod is provided with for locking the locking nut of tensioning screw rod, one end that described tensioning screw rod is positioned at pipe pile die is provided with the stretch board being connected with steel reinforcement cage end plate, also comprise the jockey between two steel reinforcement cage head and the tail in pipe pile die, the middle part of described jockey is provided with the through hole that diameter is identical with pile tube internal diameter, described jockey is provided with and prevents that concrete from flowing into the hermetically-sealed construction of this jockey inside.This application case has good practicality using concrete pump and build when pipeline carries out concreting, can carry out stretch-draw to steel reinforcement cage, do not affect and build building and its good seal performance of pipeline yet, but this application case is Shortcomings part still: because stretch board weight (heavier) and tensioning screw rod weight act on steel reinforcement cage end simultaneously, easily cause the steel reinforcement cage cage phenomenon of faling apart, have a strong impact on concrete-pile workmanship; In addition, do not establish special position for dismounting plate end to end, make production efficiency and security step-down, the waste working time.
