The specimens used for concrete strength tests are:
In order to judge the pass/fail of the test results using the same standards, it is required to use the same shape, and the dimensions etc. are specified in detail in the JIS standard. By filling concrete into a container with a predetermined shape and a bottom cover and allowing it to harden, concrete strength test specimens satisfying the aforementioned JIS standards were created.
(See Publication No. 10929).

題点があつた。[Problem to be solved by the invention] After the preparation is completed, a preparation container for concrete strength test specimens (hereinafter simply referred to as preparation container) is prepared.
The concrete strength test specimen inside was removed by cutting the container, but there was a problem in that cutting the container with a predetermined strength was a difficult task.

なか作成できないという問題点があつた。 In addition to standardizing the dimensions mentioned above, it is also required that the flatness of the bottom of the concrete strength test specimen be within a predetermined value (for example, 0.02 mm).
This flatness basically depends on the state of the top surface of the bottom cover, and on the other hand, a wall-shaped and groove-shaped guide part for holding the cylindrical body is formed by machining on this top surface. The flatness of the top surface often decreases as a result of this machining, making it difficult to create concrete strength test specimens with bottom surfaces that meet the above requirements. There was a problem.

目的とする。 Therefore, in the present invention, by forming a cutting line on the circumferential surface of the cylindrical body portion of the preparation container, it is possible to facilitate the cutting operation of the preparation container when taking out the specimen for concrete strength testing, and to achieve a predetermined flatness. By creating a single smooth flat plate with a diameter and placing it over the top of the bottom cover, it is possible to reliably create a specimen for concrete strength testing whose bottom surface flatness meets the required value. The purpose is to do so.

In the present invention, since a cut line is formed on the circumferential surface of the cylindrical body of the preparation container, it is possible to easily cut the preparation container and take out the concrete strength test specimen inside after the concrete has hardened. In addition, since a smooth flat plate formed separately from the bottom cover of the preparation container is used as a member to determine the flatness of the bottom surface of the concrete strength test specimen, it is relatively easy to maintain the flatness within a predetermined value. This smooth flat plate can be used repeatedly, unlike disposable containers.
The manufacturing cost of concrete strength test specimens can be reduced.
