Description

Technical Field

[0001] The invention relates to the field of concrete testing equipment, and in particular to a detachable testing concrete mould and a use method thereof. Background Art

[0002] At present, the experimental specimen molds used in existing laboratories mainly include assembled templates and bulk splicing templates. During the use of assembled templates, demoulding is generally difficult due to the serious adhesion between the specimen and the inner wall of the mold, while the bulk splicing template has too many parts and the assembly steps are complicated. Moreover, both types of experimental molds have technical problems of demoulding and inconvenient transportation. In the experiment, in order to enhance the firmness and anti-leakage of the experimental mold, each surface of the experimental mold needs to be fixed to form a whole. It is very inconvenient to carry the mold, and it is also very laborious to carry the test block and the mold together. At the same time, during the demoulding process, both molds need to be used with a demoulding gun and an air pump. Summary of the invention

The two first side plates are located on opposite sides of the bottom plate, and their lower sides are rotatably connected to the bottom plate through a rotating shaft. A positioning protrusion 5 is vertically arranged on the two side edges of the first side plate. Two second side plates are located on the other two sides of the bottom plate, and the lower sides of the second side plates are rotatably connected to the bottom plate through a rotating shaft. Positioning grooves 6 that match the positioning protrusions are provided on the second side plates at positions corresponding to the positioning protrusions. The first side plate is connected to the second side plates by the positioning protrusions extending into the positioning grooves. The cover plate is located above the side plate, and a limiting groove 7 is provided on the upper side edge of the first side plate along its length direction. A limiting block 8 is provided on the lower side surface of the cover plate at a position corresponding to the limiting groove. The limiting block is fixedly connected to the cover plate and can extend into the limiting groove to fix the cover plate above the first side plate and the second side plate.
