Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 It is a schematic diagram of a steel truss system without prestressed cables in the prior art; figure 2 It is a schematic diagram of a steel truss system with prestressed cables only on one vertical bar; Figure 3-Figure 5 It is a schematic diagram of three embodiments of the self-adaptive load-bearing prestressed steel truss system of the present invention. In these 5 comparative diagrams, mark 1 represents the inner chord, mark 2 represents the outer chord, mark 3 represents the web, mark 4 represents the first prestressed cable, and mark 5 represents the second prestressed cable.

[0027] Such as Figure 3-Figure 5 As shown, the three embodiments are only different in the setting positions of the prestressed cables. The adaptive load-bearing prestressed steel truss system in each embodiment includes an inner chord 1 and...

Abstract

The invention relates to a self-adaptive bearing-type prestressed steel truss system, comprising an inner chord member and an outer chord member, wherein a web member is connected between the inner chord member and the outer chord member, and prestressed inhaul cables are arranged in the inner chord member and the outer chord member. The self-adaptive bearing-type prestressed steel truss system fully utilizes the characteristics of a steel component and the inhaul cables to organically form a novel prestressed steel truss system with high structural rigidity and high bearing capacity, which can self-adaptively regulate the working state and the stressing state of all components according to the loaded condition of the system, and is particularly suitable for bearing repeated lateral load.

Description

technical field [0001] The invention relates to a prestressed steel truss, in particular to an adaptive load-bearing prestressed steel truss system suitable for resisting repeated loads. Background technique [0002] The development of contemporary society and the improvement of human material and cultural living standards continue to put forward new standards and requirements for the function and aesthetics of buildings. Designers are increasingly favoring large and lightweight architectural shapes. For example, in modern design, designers often hope that one dimension of building components is larger, while the other two dimensions are smaller, which creates a contradiction between structural stiffness, bearing capacity and component cross-sectional dimensions . [0003] Traditionally, for components subjected to unidirectional lateral loads, prestressed cables can be installed on the side of the tensile edge of the component to apply prestress to improve the internal for...
