String truss structure with load-relieving effect and implementation method

Abstract

The invention discloses a string truss structure with a load-relieving effect and an implementation method. The string truss structure comprises an upper string truss, a plurality of stay bars, a guy cable, a spherical joint fixed support and a sliding hinge support, wherein the spherical joint fixed support comprises a lower part supporting structure, a pre-embedded base plate, a reverse T-shaped sliding plate, a plurality of pre-embedded reinforcing steel bars, a fixed spherical joint, a plurality of columnar rolling bearings, an anchoring device, a plurality of damping springs and a support. The string truss structure with the load-relieving effect and the implementation method provided by the invention have the advantages of high material utilization rate, good stress performance, safety and simplicity for constructions, superior safety performance and the like.

Description

technical field [0001] The invention belongs to the technical field of large-span prestressed steel structures of building structures, and in particular relates to a string tension truss structure with load relaxation function and an implementation method. Background technique [0002] The string truss structure was first proposed by Professor M. Saitoh of Nihon University in 1986. This structure is a new type of hybrid roof system different from the traditional structure. The self-balancing hybrid structure composed of cables and intermediate compression struts is also a relatively successful long-span prestressed spatial structure in the development of hybrid structural systems. [0003] The string truss structure is characterized by a simple system, clear force, and various structural forms, giving full play to the advantages of rigid and flexible materials, and it is simple and convenient to manufacture, transport, and construct, so it has been well applied. In recent y...

Problems solved by technology

[0008] However, there are still some limitations in the application of the load mitigation system. The specific performance is: using a certain degree of deformation to relieve the force of the structure, resulting in a narrow application area, so it is more suitable for flexible structures; the application of vertical load mitigation devices using constant weights There are many, and there are few studies on horizontal load relaxation devices using springs; the application in suspensive structures is even rarer
