Description
Technical field
The present invention relates to architectural engineering prestressed Construction Technology field, particularly a kind of prestressing force intelligent tensioning method.
Background technology
At present, architectural engineering prestressed stretch-draw mainly uses manual operation oil pump control stretching force to carry out stretch-draw.This kind pre-
Stress tension method exists following not enough:
Tension stress value deviation is big, two ends pre-stress rib stretching force is asynchronous, stress applying is asynchronous, the anchoring time is short,
Discharge rate is fast, controls error big；Elongation measure not in time, inaccurate；There is measurement error and record in on-the-spot record data
Mistake；There is potential safety hazard etc. in workman's in-site measurement, operation.
Summary of the invention
For the deficiency of above-mentioned arrangement and method for construction, invention provides a kind of presstressed reinforcing steel intelligent tensioning method, this pre-should
Power muscle method for stretching, can accurately control stretching force, symmetrical synchronous tension, not affected by anthropic factor, environmental factors, stretch-draw matter
Amount height, safety is good.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
One prestressing force intelligent tensioning method of the present invention, uses prestressing force automatic Tensioning equipment and computer control system thereof
Replace manual operation control carry out stretch-draw, it is characterised in that: prestressing force intelligent tensioning system mainly by program control main frame, jack,
Oil pump, front controller, oil pressure sensor, stay-supported type displacement sensor, arch displacement measurement sensor and wireless-transmission network
Deng composition, it is with stress as Con trolling index, and elongation error is as check and correction index, and system gathers every stretch-draw by sensing technology
The operating pressure of equipment and the stretch value of steel strand wires, transfer data to system host in real time and be analyzed judging, simultaneous tension
Equipment receives system command, it is achieved stretching force and loading velocity the most accurately control, and system, always according to pre-set programs, is sent out by main frame
Go out instruction, each mechanical action of Synchronization Control every equipment, be automatically performed whole stretching process.
As a preferred technical solution of the present invention: after the most complete stretch-draw observing and controlling operation completes, system is automatic
Storage measuring and control data, main frame can be directly connected to printer output tension data form, it is possible to data are passed through wireless-transmission network
Teletransmission is to the network platform or output to office computer, by special report program, according to user require to generate character file and
Form.
The present invention is reached to provide the benefit that: changes artificial pressure fuel pump meter reading and controls stretching force, manual measurement
Control technological deficiency such as stretching force and the manometric calibrated error of elongation existence and pressure gauge reading error is relatively big, Pressure gauge
Reading is unstable, manual pressure control operating error be difficult to greatly accurately to control stretching force, manual measurement stretch value error in reading big,
Manually fill in stretch-draw record, verity is difficult to ensure that etc., really realizes stretch-draw, mud jacking " accurate, stable, automatic, safety and height
Effect ".Achieving intelligent operation and automatically monitoring, tension data automatic report generation, data are detailed, it is impossible to change, allow owner, prison
Manage relieved, this tension of prestressed tendon method, can accurately control stretching force, symmetrical synchronous tension, not by anthropic factor, environmental factors
Impact, stretch-draw quality is high, and safety is good.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, with the reality of the present invention
Execute example together for explaining the present invention, be not intended that limitation of the present invention.In the accompanying drawings:
