Embodiment Construction

[0038] Below in conjunction with accompanying drawing, the specific embodiment of a kind of prestressed steel structure member system performance test verification of the present invention is described:

[0039] Such as figure 1 As shown, a prestressed steel structure rod system includes a fixed end anchor plate 1, a steel rod 2, a steel strand 3, a tension end anchor plate 4, a tension jack 5, a first end sealing plate 6, The second end sealing plate 7, the first connecting plate 8, the second connecting plate 9, the stress sensor 10, the displacement sensor 11 and so on.

[0040]When the steel rod 2 is loaded, when the stress sensor 10 on the steel rod 2 measures the maximum deformation of the steel rod 2, the controller program automatically starts the prestressing system, and when the displacement sensor 11 measures the feedback steel rod 2 reaches zero deformation Program control can stop applying prestress; it can also continue to apply prestress. When the sensor measur...

Abstract

The invention discloses a prestress steel structure tool rod piece system. The prestress steel structure tool rod piece system comprises an intelligent controller, a software system, a tool rod and a prestress system. Under the condition that the same material is used, the prestressed steel structure tool rod piece system scheme can reduce the material consumption of the structure, so that the structure is designed to be thinner and lighter; the permanent prestress value of the prestress steel structure tool rod piece system is small, long-term adverse stress can be avoided, and the prestress loss changing along with time can be greatly reduced; the prestress steel structure tool rod piece system is a dynamic prestress system and is particularly economical and effective under the condition that the ratio of live load to dead load is high. The high-strength steel is fully utilized, the weight of the steel rod piece is reduced, the strength is improved, and the turnover use of the steel member is improved, so that high-quality development such as energy conservation, environmental protection and construction safety is realized.

Description

technical field [0001] The invention belongs to the technical field of prestressed steel structures, and in particular relates to a prestressed steel structure tool bar system. Background technique [0002] The prestressed steel structure can save 10% to 40% of steel than the traditional steel structure, and can use a large amount of high-strength steel, which is lighter, stronger, better and more economical. [0003] At present, prestressed steel structures are mainly used in the field of building structures, and are rarely used in temporary structures and mechanical equipment. Prestressed steel structure technology needs to be developed and innovated. For example, make full use of high-strength steel, reduce the weight of steel rods, improve the turnover of steel components, and achieve controllable stress and deformation, so as to achieve the goals of energy saving, environmental protection, and construction safety. Among them, the research and development of prestressed...
