Description

Technical Field

[0001] The present application relates to the technical field of concrete moulds, and in particular to a rapid demoulding device for preventing a sprayed concrete test block from being twisted. Background Art

[0002] Cubic test blocks, also known as shotcrete test blocks, reflect the compressive strength of concrete. The compressive strength of concrete test blocks is an important indicator of the quality of concrete construction in a project. Whether the test block production method and molding quality are appropriate is very important.

[0003] During the construction process, when spraying concrete test blocks, the traditional plastic molds are not rigid enough and the impact force is large when spraying the test blocks, which often leads to distortion of the sprayed concrete test blocks. Severe deformation directly affects the subsequent compressive strength test. In addition, since the sprayed concrete test blocks are relatively large, many of them cannot be removed smoothly by air pressure demolding. Forced demolding will damage the mold or the test block. Therefore, the traditional plastic molds for spraying concrete need to be improved and developed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0031] The rigidity of traditional plastic molds is not enough, and the impact force when spraying test blocks is large, which often causes the sprayed concrete test blocks to twist and deform. Severe deformation directly affects the subsequent compressive strength test. In addition, due to the large size of the sprayed concrete test blocks, many of them cannot be removed smoothly by air pressure demolding. Forced demolding will damage either the mold or the test block. This application is used as a forming mold for sprayed concrete test blocks. After the two movable side panels are closed, they are fixed by rotating the buckle. The operation is simple and convenient, and the test block molding is standard, avoiding the test block distortion problem caused by the insufficient rigidity of the plastic mold; the test block demolding process is convenient and quick, and you only need to open the buckle of the movable side panel and put down the movable side panel to take out the test block; due to the simple demolding of the test block and the high strength and rigidity of the steel plate, the utility model device has a high reuse rate. Before each use, you only need to clean it, close the movable side panel, and brush on the release agent before use.
