A kind of back-shaped concrete member for test

Abstract

The invention discloses a concrete member for a hui-shaped test. The concrete member comprises a concrete member body, wherein the middle part of the concrete member is in a hollow structure; the concrete member is provided with concrete-member prepared hole channels; a screw is arranged in the prepared hole channels in a penetrating manner; the two sides of the screw are provided with nuts; the loading size is controlled by reading of a vibrating-string frequency meter. The concrete member disclosed by the invention has the advantages that due to adoption of the loading method in the technical scheme, the stressing is reliable, a loading device is simple in structure and convenient to operate, and the loading process of the concrete member in the test can be greatly simplified; the size of the load value is effectively controlled, and a loading appliance can be repeatedly used; the concrete member can be loaded, and simultaneously the complex erosion environment can be simulated; the bending performance and the erosion rule of the upper part and the lower part of the concrete member can be compared under the condition with same environment and load.

Description

technical field [0001] The invention relates to the field of concrete component tests, in particular to concrete components for comparative tests under the coupled action of simulated erosion environment and long-term constant load. Background technique [0002] At present, most of the studies on the flexural performance tests of concrete members under load are carried out by means of heavy loading, hydraulic loading or mechanical loading. Due to the relatively small space of equipment for artificially simulating the erosion environment (such as carbonization chambers, salt spray chambers, etc.), coupled with the fact that the loader is large in size, occupies a large area, and is inconvenient to move or adjust after loading, it is difficult to carry out Simultaneous long-term loading of concrete members in erosive environment simulation tests. In addition, when conducting comparative tests on the flexural performance of concrete with different mix ratios and structural req...

Due to the relatively small space of equipment for artificially simulating the erosion environment (such as carbonization chambers, salt spray chambers, etc.), coupled with the fact that the loader is large in size, occupies a large area, and is inconvenient to move or adjust after loading, it is difficult to carry out Simultaneous long-term loading of concrete elements in erosive environment simulation tests

In addition, when conducting comparative tests on the flexural performance of concrete with different mix ratios and structural requirements, it is difficult to achieve a high degree of consistency in the stress of two independent concrete members
