Columnar forming device for concrete materials

Abstract

The invention relates to a columnar forming device for concrete materials. The columnar forming device comprises a casting mould which is generally of a tubular structure, wherein the casting mould is divided into two semicircles by taking the center line as a base point, namely an upper mould and a lower mould respectively, and the upper mould and the lower mould have same structures and are connected with each other. The columnar forming device is light in dead weight and easy to assemble and disassemble, and can be used for greatly reducing the amount of testing labor and saving the manpower. In addition, as the assembling parts of the device are few and the size and length are reasonable, the uniformity of a concrete testing block can be effectively improved so as to achieve the purpose of improving the testing precision.

Description

technical field [0001] The invention relates to a columnar molding device for concrete materials. Background technique [0002] Separate Hopkinson (Hopkinson) pressure bar system test equipment is one of the most important test methods in the series of tests to study the dynamic mechanical properties of materials. This equipment is mainly used for the experimental research of dynamic mechanical properties of plain concrete, fiber concrete, and other types of concrete materials. [0003] The processing efficiency and production quality of the concrete test blocks used in the test directly determine the progress of the test and the validity and reliability of the test data. [0004] First of all, the existing concrete rod pouring mold has the disadvantages of heavy weight, cumbersome assembly and disassembly process, etc., which makes the pouring and vibration of the concrete test block a lot of manpower and time-consuming, which affects the test efficiency and restricts the ...

AI Technical Summary

Problems solved by technology

[0004] First of all, the existing concrete rod pouring mold has the disadvantages of heavy weight, cumbersome assembly and disassembly process, etc., which makes the pouring and vibration of the concrete test block a lot of manpower and time-consuming, which affects the test efficiency and restricts the test process;

[0005] Secondly, the size of the existing mold is relatively long, and the drop of the concrete mixture is relatively large when it is poured into the mold, and it is easy to segregate after being vibrated by the vibrating table, which affects the uniformity of the concrete test block and greatly reduces the objectivity of the test results;

[0006] Finally, since the existing mold is assembled in 4 parts, the surface of the bar after demolding is not smooth, which adds unnecessary difficulty and workload to the later processes of cutting and grinding the bar
