Concrete temperature stress testing machine with separable mold and vibration

Abstract

The invention discloses a concrete temperature stress testing machine achieving mold separable vibrating. The testing machine comprises a main testing machine body, a concrete sample mold detachably connected with the main testing machine body, and a deformation measurement device. According to the concrete temperature stress testing machine achieving mold separable vibrating, mounting and demounting of the concrete sample mold and the main testing machine body are convenient, the concrete sample mold can be independently poured and vibrated after being demounted, the concrete sample mold is mounted on the main testing machine body for relevant temperature stress testing after the vibrating quality requirement is met, the pouring quality of concrete is greatly improved, and the credibility and comparability of the test result are better.

Description

technical field [0001] The invention relates to the technical field of concrete temperature stress and deformation testing, in particular to a concrete temperature stress testing machine with separable and vibrated molds. Background technique [0002] Concrete Temperature Stress Testing Machine (TSTM) has the function of simultaneously measuring the elastic modulus, creep, relaxation, cracking stress and characteristic fracture temperature of concrete and other material mechanical parameters. It can simulate different constraints in the laboratory and establish engineering structures. the relationship between. The concrete temperature stress testing machine (TSTM) is an effective test device for comprehensively evaluating the crack resistance of concrete. [0003] The current concrete testing machine and the specimen mold are fixed and cannot be disassembled, that is, the concrete specimen must be poured on the testing machine, and the concrete in the specimen mold is vibra...

AI Technical Summary

Problems solved by technology

As we all know, concrete is a kind of artificial synthetic material, which has great natural discreteness. The size of concrete temperature stress test specimens is relatively large, mostly 150mm*150mm*1500mm. The concrete is fully vibrated, which will affect the quality of the concrete; and long-term vibration will also affect the performance of the testing machine

Although the same mix ratio can be controlled during different batches of tests, the quality of the concrete is not good, and the test results naturally vary greatly

Due to poor vibration quality, the reliability of the test results is low, and the test results of different batches of concrete are poorly comparable

In addition, due to the poor quality of concrete, the current concrete temperature stress testing machine only tests for homogeneous concrete, and cannot carry out related temperature stress tests on the combination of new and old concrete.
