Abstract
The invention discloses an automatic prestress tensioning control system. The control system comprises an intelligent tensioning oil pump, an intelligent jack and a control system body, wherein the intelligent tensioning oil pump and the intelligent jack are both controlled by the control system body. The control system body comprises a computer, a force transducer and a displacement sensor, the computer is used for controlling the intelligent tensioning oil pump and the intelligent jack, and the force transducer and the displacement sensor are used for measuring beam body data. The control system body further comprises a storage module used for storing data in the tensioning process. Not only can two bundles of steel strands be tensioned symmetrically and synchronously, but also the two ends of one bundle of steel strands can be tensioned and stopped synchronously, and the single end can be tensioned automatically with pause in a grading mode, and namely the control system can be used for a equipment combination under the working condition; the value accuracy of the automatic prestress tensioning control force can be up to +/-1.5%, and automation control over the tensioning process is achieved without being affected by human factors.
Description
Technical field
The present invention relates to a kind of prestressing force automatic tensioning control system.
Background technology
Key link in pre-stress construction is mainly to this technique of the stretch-draw of presstressed reinforcing steel, the stress loss that between the mensuration of the elongation value of stretching that has prestressed reinforcement wherein relating generally to and duct, phase mutual friction produces, also be included in the stress loss that when prestressing force is carried out to stretch-draw, its anchoring produces simultaneously, and coagulation scholar is carried out to stress loss and the loss of concrete shrinkage and creep loss stress relaxation that elastic compression is brought.In the construction application of current reality, elongation value of stretching measurement is not very accurate.Artificial steel ruler measurement is the Main Means that Extension Values of Prestress Reinforcements is measured, and the error on reading is appearance thereupon just, and such error is all bigger than normal in the ordinary course of things.Measuring process is slow, and situation about being caused by man's activity is more.Therefore, existing prestressing force pull system, error is larger, and stretching mode is more single.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, and a kind of prestressing force automatic tensioning control system is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of prestressing force automatic tensioning control system of the present invention, comprises intelligent tensioning oil pump, intelligent jack and control system, and described intelligent tensioning oil pump and described intelligent jack are all by described control system control.
Further, described control system comprises computer, load cell and displacement transducer, and described computer is used for controlling described intelligent tensioning oil pump and described intelligent jack; Described load cell and described displacement transducer are for the measurement to beam volume data.
Further, described control system also comprises memory module, in order to store the data in stretching process.
The beneficial effect that the present invention reaches is:
The present invention both can realize the symmetrical synchronous tension of two bundle steel strand, can realize again single bundle steel strand two ends synchronous tension, synchronization stall, also can realize single-ended automatic Tensioning, classification pause stretch-draw, can be used for the device combination under above-mentioned operating mode; The control value precision of prestressing force automatic Tensioning can reach ± and 1.5%, realized stretching process automation control, be not affected by human factors.
