Abstract
The utility model provides a prestressed concrete is stretch -draw subassembly of sheet pile for no reason, includes the tentioning screw rod of being connected with the stretch -draw machine, is located outer stretch -draw tailboard of concrete pile mould and the tentioning head board of being connected with the tentioning screw rod, stretch -draw tailboard or tentioning head board or both all set up the hardy hole that corresponds with prestressing tendons, and the hardy hole is the through -hole, and calabash aperture diameter corresponds with prestressing tendons, and calabash macropore diameter corresponds with the prestressing tendons pier nose. The utility model provides a stretch -draw subassembly, the hardy hole that will be located the end plate originally uses with tentioning head board and stretch -draw tailboard direct bonding, and has saved the use of end plate to reduce the loaded down with trivial details process of preparation end plate, practiced thrift the cost.
Description
Technical field
The utility model belongs to prestressed concrete prefabrication component technology field, is specifically related to the stretch-draw assembly of a kind of prestressed concrete sheet pile for no reason.
Background technology
Concrete-pile is widely used in the foundation engineering of all kinds of building, at present, the prestressed-concrete pile that China mainly uses mainly contains pile tube and square pile, the primary structure of these two kinds of stakes is similar, mainly comprise steel reinforcement cage, concrete, end plate, the parts such as anchor ear plate, concrete and steel reinforcement cage form pile body, steel reinforcement cage is then by non-prestressing tendon, presstressed reinforcing steel and tie hoop composition, the two ends of pile body are pile crown, traditional pile crown is made up of end plate and anchor ear plate, end plate is arranged on the both ends of pile body, anchor ear plate and end plate are by weld or the mode such as riveted joint is fixed together, thus further by end plate anchor ear on pile body.
In prior art for the tip plate configurations of pile tube as shown in Figure 1, for disc, the hardy hole 2 of multiple rounded distribution is provided with on the surface at end plate 1, hardy hole quantity, position and presstressed reinforcing steel quantity, position are identical, wherein cucurbit aperture 21 diameter is corresponding with presstressed reinforcing steel diameter, and cucurbit macropore 22 diameter is corresponding with presstressed reinforcing steel pier nose.As shown in Figure 2, in prior art, stretch-draw assembly comprises the tensioning screw rod 3 be connected with stretching machine, the tensioning head plate 4 be connected with tensioning screw rod 3, be arranged in the stretch-draw tailgate (figure is not depending on going out) outside mould, connect tensioning head plate 4 and the set bolt 5 of end plate 1, tensioning head plate 4 arranges the screw corresponding with set bolt 5.
When tensioned prestressing bar, end plate plays an important role.But, there is following problem when utilizing end plate to carry out stretch-draw: the processing and fabricating program of (1) end plate is many, material and processing charges high; (2) need when end plate is assembled with anchor ear plate to weld or rivet, add operation, take cost of labor and device resource; (3) end plate material is thick and heavy, and anchor ear sheet material matter is gently thin, all easily causes anchor ear plate to be out of shape, affect finished peg quality in the process assembled, transport, store and use; (4) include end plate in finished peg, add the cost of finished peg.
In sum, in prestressed-concrete pile, reduce the use of end plate, can reach and save finished peg production cost, improve finished peg quality, reduce production process, the object of enhancing productivity.
Summary of the invention
The purpose of this utility model is just the stretch-draw assembly providing a kind of prestressed-concrete pile without the need to end plate for solving the deficiencies in the prior art.
The purpose of this utility model realizes with following technical proposals:
The stretch-draw assembly of a kind of prestressed concrete sheet pile for no reason, comprise the tensioning screw rod be connected with stretching machine, the tensioning head plate being positioned at the stretch-draw tailgate outside concrete-pile mould and being connected with tensioning screw rod, described stretch-draw tailgate or tensioning head plate or both the hardy hole corresponding with presstressed reinforcing steel is all set, hardy hole is through hole, cucurbit hole diameter is corresponding with presstressed reinforcing steel, and cucurbit diameter macropores is corresponding with presstressed reinforcing steel pier nose.
Hardy hole internal diameter is internal thread.
Described hardy hole quantity is corresponding with presstressed reinforcing steel.
Described cucurbit macropore establishes internal thread.
Described hardy hole internal thread is corresponding with set bolt.
The stretch-draw assembly that the utility model provides, is directly combined the hardy hole being originally positioned at end plate with stretch-draw tailgate with tensioning head plate, and eliminates the use of end plate, thus decreases the cumbersome process making end plate, has saved cost.
Accompanying drawing explanation
Fig. 1 is prior art end plates structural representation;
Fig. 2 is the stretch-draw assembly schematic diagram having end plate stake in prior art;
Fig. 3 is the stretch-draw assembly schematic diagram of the utility model sheet pile for no reason.
Detailed description of the invention
The stretch-draw assembly of the utility model prestressing force sheet pile for no reason, as shown in Figure 3, hardy hole 2 on original end plate is arranged on tensioning head plate 4 or stretch-draw tailgate, and cucurbit macropore 22 is set to internal thread, hardy hole quantity is corresponding with presstressed reinforcing steel 6, when such the utility model uses, first presstressed reinforcing steel is passed cucurbit macropore, then move in cucurbit aperture, because cucurbit hole diameter is less than pier nose diameter, therefore presstressed reinforcing steel is fixed by cucurbit aperture, then the cucurbit macropore of tensioning head plate or stretch-draw tailgate is passed with set bolt, reinforce and be connected with mould, described tensioning head plate and stretch-draw tailgate are arranged at outside mould.
