Problems solved by technology

The current creep research is done through common static tensile test equipment, but the existing static tensile test equipment is more complicated in design, not only costly, but also very troublesome to maintain, and has a great influence on the tensile force. The detection is not direct and accurate enough, which affects the accuracy of the creep test

Abstract

The invention discloses a concrete tension-compression dual-function dynamic creep test device, and relates to the field of building tests. The concrete tension-compression dual-function dynamic creeptest device comprises a base and a top plate; a plurality of stand columns are connected between the base and the top plate; a tension sensor is vertically connected to the center of the top of the base and connected with a control computer through a data line; an end plate is connected to the top of the tension sensor; a hydraulic cylinder is vertically embedded in the center of the top plate and connected with an end plate; and concrete columns are fixed to the two end plates through a plurality of fixing bolts. The concrete tension-compression dual-function dynamic creep test device is simple in structure, low in cost, good in stability in use, very direct and accurate in detection of tensile force and high in creep test precision.

Description

technical field [0001] The invention relates to the field of building tests, in particular to a dual-function dynamic creep test device for concrete tension and compression. Background technique [0002] Concrete creep refers to the deformation of concrete that increases with time in addition to elastic deformation under load. The creep of concrete is an inherent characteristic of the material itself, and it is an important factor to be considered in the design and calculation of concrete structures. The current creep research is done through common static tensile test equipment, but the existing static tensile test equipment is more complicated in design, not only costly, but also very troublesome to maintain, and has a great influence on the tensile force. The detection is not direct and accurate enough, which affects the accuracy of the creep test. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a concrete t...
