Synchronous computer controller device for overall tension and construction method

Abstract

The invention discloses a synchronous computer controller device for overall tension and a construction method. The device comprises a mechanical system, a hydraulic system and a control system, wherein the mechanical system comprises a tensioned space cable structure, a steel tension cable and a tension tool, wherein the steel tension cable is connected with the tensioned space cable structure and the tension tool respectively; the hydraulic system comprises a hydraulic pump station, a hydraulic jack group and various hydraulic valves; the hydraulic jacks are connected with the hydraulic pump station; tensile force is applied to the tension tool; the control system comprises a computer and a main control cabinet; the main control cabinet is connected with a computer, the hydraulic systemand the mechanical system respectively; and the main control cabinet comprises a communication control board, a PLC (Programmable Logic Controller), a phase sequence control relay, various interface boards, a transmission line and a remote monitoring sensor. The device has the advantages of simple manufacturing process, economical efficiency, reasonable manufacturing cost, easiness and convenience for operating, high synchronous control accuracy and the like.

Description

technical field [0001] The invention relates to the technical field of building tensioning construction, in particular to an overall tensioning device and construction method for a prestressed space structure. Background technique [0002] In the modern large-scale building roof cable net structure, the traditional method of building a full house scaffolding to construct the roof not only occupies a huge space and affects the construction of other processes under the roof, but also wastes a lot of materials and prolongs the construction period; modernization The construction method of hoisting the roof cable net requires more than ten cranes to operate simultaneously to meet the structural construction and architectural design requirements, which will inevitably invest a lot of money and increase the construction cost. The above two construction methods are not as good as the synchronous overall tensioning construction method using many hydraulic jacks (the number depends on...

[0002] In the modern large-scale building roof cable net structure, the traditional method of building a full house scaffolding to construct the roof not only occupies a huge space and affects the construction of other processes under the roof, but also wastes a lot of materials and prolongs the construction period; modernization The construction method of lifting the roof cable net requires more than ten cranes to run at the same time to meet the requirements of structural construction and architectural design, which will inevitably invest a lot of money and increase construction costs.

The above two construction methods are not as good as the synchronous overall tensioning construction method using many hydraulic jacks (the number depends on the number of radial cable nets on the roof)
