Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection devices, in particular to a mold for detecting the performance of fair-faced concrete. Background Art

[0002] Fair-faced concrete is a manifestation of architectural modernism, also known as decorative concrete due to its highly decorative effect; the basic idea is that after the concrete is poured and formed, there is no need for any painting, tiling, stone pasting and other materials.

[0003] Common fair-faced concrete is mostly cuboid. In order to verify the quality performance of fair-faced concrete, it is necessary to make test blocks of different thicknesses for fair-faced concrete and then conduct performance tests.

[0004] Existing fair-faced concrete molds are generally directly made of plastic material to form a cavity with an opening, and columns are also arranged in the cavity to pour fair-faced concrete test blocks in the shape of a cuboid with mounting holes in the cavity.

[0005] However, the fair-faced concrete test block solidifies directly in the mold cavity, and the column is also inside the fair-faced concrete test block. Directly pulling out the fair-faced concrete test block from the cavity is likely to damage the test block; such a mold is not convenient for workers to take out the fair-faced concrete test block from the cavity, delaying the subsequent detection efficiency of the quality performance of the fair-faced concrete test block. Summary of the Utility Model

[0006] In view of the above problems, the utility model provides a mold for detecting the performance of fair-faced concrete, aiming to improve the demolding efficiency of fair-faced concrete test blocks and the detection efficiency of the quality performance of fair-faced concrete test blocks.

[0007] In order to achieve the above invention purpose, the technical scheme adopted by the utility model is as follows:

[0008] Provide a mold for detecting the performance of fair-faced concrete, including: a mold body, in which a pouring cavity is arranged; a cover plate for covering the pouring cavity; a column rotatably arranged on the cover plate, with one end inside the pouring cavity and the other end outside the pouring cavity for workers to twist, so as to loosen the column from the test block; a lifting plate liftably arranged in the pouring cavity; a lifting component for driving the lifting plate to move upward in the vertical direction, so as to push the test block out of the pouring cavity.

[0009] Further, the mold further includes: an installation cylinder vertically arranged on the cover plate, and the column is arranged in the installation cylinder through threaded connection.

[0010] Further, the cover plate is hinged to the mold body.

[0011] Further, the mold further includes: a hand-held rod, which is installed perpendicular to the column and is disposed at one end of the column away from the casting cavity.

[0012] Further, along the vertical direction, a visible window is provided on the mold body, and a transparent glass plate is installed in the visible window; along the vertical direction, scale lines are further provided on one side of the visible window.

[0013] Further, the mold further includes a plastic film, which is laid in the casting cavity, between the test block and the inner wall surface of the casting cavity, and also between the column and the test block.

[0014] Further, the mold further includes a bracket. The mold body is disposed on the bracket, and the lifting member is disposed below the bracket. The piston rod of the lifting member passes through the bracket and is connected to the lifting plate.

[0015] The beneficial effects of the present utility model are as follows: In the present utility model, the column is rotatably disposed on the cover plate, with one end in the casting cavity and the other end outside the casting cavity. The fair-faced concrete specimen is in the casting cavity, allowing the staff to twist the column repeatedly to loosen the column from the test block, facilitating the staff to take out the column from the test block; in the present utility model, the lifting plate can also be driven by the lifting member to move upward along the vertical direction to push the test block out of the casting cavity, thereby taking out the test block from the mold. By using the present utility model, the demolding efficiency of the fair-faced concrete specimen can be effectively improved, and the rate of subsequent fair-faced concrete performance detection can be increased.
