Detailed Description
The core of the utility model is to provide a concrete test piece sample preparation mould so as to solve the problem that the test piece cannot meet the test requirement or the test data deviation caused by damaging the appearance quality of the test piece in the mould stripping process.
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 and 2, fig. 1 is a schematic perspective view of a concrete sample preparation mold according to an embodiment of the present utility model; fig. 2 is a cross-sectional view of a concrete test piece sample preparation mold provided in an embodiment of the present utility model.
The embodiment of the utility model discloses a concrete test piece sample preparation mould, which comprises a box body 1 with an opening at the upper part, a moving plate 2 arranged at the bottom of the box body 1, and a screw rod 3 screwed on the bottom plate of the box body 1.
Wherein, the movable plate 2 is in clearance sliding fit with the side wall of the box body 1. One end of the screw rod 3 is abutted with the moving plate 2, the other end of the screw rod 3 extends out of the box body 1, and the screw rod 3 is used for driving the moving plate 2 to move towards the opening direction of the box body 1.
In the concrete test piece sample preparation mold provided by the embodiment of the utility model, in the practical application process, the side wall of the box body 1 and the movable plate 2 are uniformly coated with the release agent, then concrete is poured into the mold for uniform vibration, and after the predetermined strength is reached, the movable plate 2 is driven to move towards the opening direction of the box body 1 by screwing the screw 3, so that the concrete test piece is ejected out of the box body 1 to finish the demolding.
