Annular specimen tensile testing device and realizing method thereof

Abstract

The invention discloses an annular specimen tensile testing device and a realizing method thereof. The annular specimen tensile testing device comprises tensile equipment, a first connection joint, a second connection joint, a first connection plate, a second connection plate, a first separation disc, a second separation disc, an annular specimen, a first equipment bolt, a second equipment bolt, a first connection bolt, a second connection bolt, a first fixing bolt, a second fixing bolt, a first limiting bolt and a second limiting bolt. The annular specimen tensile test device has the advantages that the structure is simple, and the design is scientific and reasonable; compared with the traditional tensile disc which is customized to different annular specimens, the device is suitable for performing tensile test on the annular specimen with multiple modulus diameters, the suitability is strong, and the repeated utilization is realized; the connection structure of the parts is simple, the force transfer path is clear, and the load can be effectively applied to the specimen.

Description

technical field [0001] The invention relates to the technical field of civil engineering building structure tests, in particular to a ring-shaped sample tensile test device and a realization method thereof. Background technique [0002] In recent decades, with the improvement of the social and economic level, the construction industry has made great progress, which is reflected in the renewal and advancement of architectural concepts and theories, the development and replacement of building materials and equipment, and the improvement and innovation of building construction technology methods. In order to better adapt to the new development situation and the subjective and objective requirements for building structures, a large number of old buildings are faced with the problem of demolition, reconstruction and reinforcement. For the reinforcement and repair of concrete structures in construction engineering, methods such as enlarging the section, outsourcing steel reinforce...

Problems solved by technology

However, the existing device has high manufacturing costs, low applicability, and is difficult to recycle. It can only load samples of specific specifications and sizes. Therefore, it is necessary to customize a new loading device for samples of different specifications and sizes, and once After use, it cannot be compatible with tensile tests of other specimen sizes, resulting in great waste, which is contrary to the concept of low-carbon and energy-saving
