Abstract

The invention relates to a cable force test device for a space cable structure, and the device comprises a support which serves as a vertical bearing member of the cable force test device; the net rack platform is supported by the support, the net rack platform is formed by connecting net rack rod pieces and bolt balls through high-strength bolts, and the bolt balls comprise an upper chord ball and a lower chord ball; the inhaul cable is arranged below the net rack platform, and two ends of the inhaul cable are connected with a lower chord ball of the net rack platform; the supporting rod is arranged below the net rack platform, the lower end is connected with the inhaul cable body, and the upper end is connected with a lower chord ball of the net rack platform; the tensioning tool is arranged on the inhaul cable and used for tensioning the inhaul cable to generate prestress; the platform reinforcing device is arranged above the net rack platform and is connected with an upper chord ball of the net rack platform; and the platform displacement monitoring system is arranged on the net rack platform. The cable force testing device can be used for cable force testing experiments of different cable structural forms, and is low in testing site requirement, high in adaptability, safe, convenient, simple in structure replacement, high in economical efficiency and worthy of engineering popularization.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a test device for building structures, in particular to a cable force test device for a space cable structure. Background technique [0002] In recent years, with the rapid development of construction technology, cable structures have been widely used in modern construction projects and bridge construction projects. The application of prestressed cables can reduce the structure size, shorten the construction period, save materials, and have advantages such as economic advantages, which are widely used, especially in stadiums, exhibition halls, large-span coal shed construction, and large-span bridges. [0003] The safety of the cable structure has also become very important, and the detection of the cable force is an important means to ensure its safety. In the engineering construction and the work of the cable after the construction is completed, the cable force detection of ...
