Description
Technical Field
The invention relates to the field of prestressed steel strand equipment, in particular to a bridge prestressed whole-bundle steel strand pressing and conveying device.
Background
The bearing capacity of the concrete precast bridge is controlled by the steel strands which penetrate through the reserved holes and are subjected to the accurately controlled tensioning process, so that the number of the steel strands arranged on each precast beam is accurately calculated according to the total load borne. For the threading process of the steel strands, the beam-making field in China adopts a 'bundling threading process' in the early stage, and each steel strand is pre-sized, arranged in order and bundled into a bundle; and then the steel strand is pulled by a winch to penetrate into the reserved hole, and as disordered winding does not exist, stress of each steel strand is basically uniform during tensioning, and the optimal bearing capacity of the whole beam body can be achieved. However, the operations of "restraint making" and "restraint pulling" are all completed manually, which is a quite labor-consuming process.
Since the efficiency of the 'single reeving process' produced later is several times that of the 'bundling reeving process', and the single reeving machine has simple structure and low price, the single reeving process is rapidly popularized to all precast beam fields in the country under the drive of the economic benefit of the market. The serious hidden trouble of the process is as follows: because the superposition influence of the 'spiral line' on the outer surface of the steel strand and the 'hyperbolic' drooping radian of the reserved hole forces a single steel strand to generate unpredictable 'disordered winding' in the penetrating process, the steel strand is a steel cable stranded by seven steel wires together, the outer diameter of the steel strand is actually a spiral line with a longer pitch, the single rope penetrating process is in actual operation, when the steel strand penetrating the reserved hole is crowded gradually, the spiral lines are just like rifles in a gun bore, the steel strand penetrating after extrusion rotates and winds, the enveloping outer diameter of the whole steel strand is increased undoubtedly, but the reserved hole diameter of the beam body is fixed and unchanged, when S bending occurs in the reserved hole or various adverse factors are accidentally superposed, the conveying resistance of the steel strand is greatly increased, in order to forcibly penetrate the last steel strand, only the conveying force is increased, due to the strong conveying force and the rotation, the steel strands can obliquely drill through the cement layer of the beam body along the spiral line, and the steel strands are drilled outwards from the middle of the beam body or inwards from adjacent reserved holes.
When the situation occurs, when the last steel strand cannot be penetrated, an operator can select to retract the drilled part, then forcibly penetrates a steel strand at the other end, the last steel strand cannot be completely penetrated due to extrusion of the penetrated steel strand in the reserved hole, the operator often selects how deep the operator can penetrate, how deep the operator can penetrate is often caused, and then the operator cuts off the broken pieces, so that the fraud behavior which is difficult to find from the outside can bring potential hidden troubles to the whole route.
In addition, except the above-mentioned circumstances, the unordered winding of steel strand wires causes the steel strand wires that penetrate to differ in length, and according to the steel strand wires of 65Mn alloy steel material of manual, its elastic modulus E is up to more than 200, in the condition of fixing the both ends of the higher 65Mn steel strand wires of stranded elastic modulus together, exerts the critical pulling force of elastic deformation, the condition that the stress of the shorter steel strand wires is big, the stress of longer steel strand wires is little, even not atress at all appears.
In addition, the speed of a single rope penetrating process is very high, the length manually cut by a civil worker is difficult to control, in order to be stable, long and short, the steel stranded wires at two ends of the beam body are provided with the allowance of about 1 meter, the allowance is calculated according to the waste of 0.5 meter at each end of the steel stranded wires, each beam is provided with hundreds of steel stranded wires, the whole line is provided with thousands of steel stranded wires of bridges, and the waste is really a very striking number.
In order to avoid the defects and problems of a single reeving process and a bundling reeving process, at present, the requirement for whole-bundle reeving of domestic T-beams and box beams is strong, and production enterprises urgently need a mature device for production so as to improve the prestress precision and the reeving efficiency under the anchor and improve the production quality.
