Description

Anti-dislocation preparation device for researching reinforced concrete bending resistance prism test block The utility model belongs to the technical field of concrete material performance research equipment, and particularly relates to an anti-dislocation preparation device for a prism test block for researching the bending resistance of reinforced concrete. Background At present, concrete is used as one of the most commonly used materials in the construction industry and is widely applied to various structural engineering. In the manufacture of concrete test pieces, conventional concrete test piece boxes are typically used to carry only a single type of concrete. Although these test pieces boxes can hold and shape concrete, there are often certain problems in performing different performance concrete casting. For example, when reinforcing a common concrete member, reinforcing performance concrete needs to be added, but due to the property difference of the two types of concrete, the traditional test piece box cannot accurately and uniformly combine the two types of concrete during pouring, namely, the concrete to be reinforced is ensured not to deviate or misplacement, so that the concrete sizes of the reinforcing layers are the same, and the test result cannot accurately reflect the actual performance after reinforcement. Meanwhile, in the using process of the common concrete piece, the bending resistance is easy to be reduced due to the factors of uneven stress, environmental change and the like. In order to improve the durability and the service life of a concrete structure, reinforcement technology is continuously developed in recent years, and research on the bending resistance of the reinforced concrete becomes an important research direction. The existing concrete bending resistance research is mostly dependent on standardized test blocks, but the existing preparation device has the problems that effects of different reinforcement modes cannot be accurately simulated, the preparation process is complex and the like, and the depth and the breadth of the research are limited. In view of the above problems, there is an urgent need in the art for a reinforcement device that can effectively fix concrete and avoid misalignment or offset to ensure accurate pouring and reinforcement of different concretes. Disclosure of utility model Aiming at one or more of the defects or improvement demands of the prior art, the utility model provides an anti-dislocation preparation device for researching the bending resistance of reinforced concrete prism test blocks, so as to solve the problems that in the prior art, when the prism test blocks are prepared, common concrete pieces are easy to deviate or misplace in the process of pouring the reinforced concrete, and the test blocks are poor in molding quality and inaccurate in test result.
