Problems solved by technology

The following problems still exist in the existing reaction force frame supporting device: (1) the structure is complex and the function is single, most of them can only provide one-way reaction force, and cannot provide two-way reaction force of tension and compression; (2) the scope of application is small, most of them can only meet the single Point loading requirements make it impossible to carry out multi-point loading tests; (3) Poor installation, disassembly, and adjustment performance affect the low efficiency of the reaction force frame

Abstract

The invention relates to a pull rod type planar counter-force device. The pull rod type planar counter-force device comprises a first left upright, a second left upright, a first right upright, a second right upright, a first groove-type cross beam connected between the first left upright and the second left upright, a first anchoring beam, a second groove-type cross beam connected between the first right upright and the second right upright, a second anchoring beam, a box-type longitudinal beam, a first high-strength pull rod which connects the first groove-type cross beam with the box-type longitudinal beam and a second high-strength pull rod which connects the second groove-type cross beam with the box-type longitudinal beam. According to the pull rod type planar counter-force device, the high-strength pull rods are adopted, the beam-type counter-force frame tension and compression two-way supporting function is achieved, the installation is convenient, the adjustable performance is strong, the application range is wide, and the pull rod type planar counter-force device can be used for multiple types of civil engineering structures and component testing research.

Description

technical field [0001] The invention belongs to the field of structural test devices, and in particular relates to a pull rod type planar reaction force device. Background technique [0002] The load reaction device and the pedestal are one of the key conditions to meet the load design of the civil engineering structure test, realize the load diagram, the structural force and boundary conditions, and ensure the normal test loading. The reaction frame is the most commonly used load reaction device in civil engineering structural tests, and it is an inseparable load support device for carrying out experimental teaching tests and various scientific research tests. The following problems still exist in the existing reaction force frame supporting device: (1) the structure is complex and the function is single, most of them can only provide one-way reaction force, and cannot provide two-way reaction force of tension and compression; (2) the scope of application is small, most of ...
