Abstract

The invention relates to a lever-type apparatus and method for measuring the demolding performance of concrete. The existing concrete demolding device is complicated in structure, the evaluation method is compilicated in operation, time and manpower are wasted, the expense is high, and the demolding performance of the concrete is difficult to evaluate comprehensively. Concrete and a mold of the concrete are vertically arranged on a base, the middle part of a pressing rod is hinged to the top end of a stand column, the other end of the pressing rod is hinged to one end of a first connecting rodby virtue of a pulling rod, the other end of the first connecting rod is hinged to one end of a second connecting rod by virtue of a force measuring sensor, and the other end of the second connectingrod is separately detachably connected with an upper pressing plate or a lower pressing plate. When in operation, a limiting ball is firstly rotated to make the lower end of the second connecting rodbe separately connected with the upper pressing plate or the lower pressing plate in a threading manner, the pressing rod drives the pulling rod to move upwardly, the pulling rod pulls the upper pressing plate or the lower pressing plate upwardly successively by virtue of the first connecting rod, a force measuring sensor and the second connecting rod until the upper pressing plate or the lower pressing plate and the concrete bonded with the upper pressing plate or the lower pressing plate move relative to each other in a mold. The lever-type apparatus and method are used for measuring the demolding performance of the concrete.

Description

technical field [0001] The invention specifically relates to a device and method for measuring the demoulding performance of concrete in a lever type. Background technique [0002] With the rapid development of the catering industry, kitchen waste oil continues to increase, and the phenomenon of waste oil returning to the dining table occurs from time to time, which has aroused widespread concern. Therefore, all walks of life began to seek technical solutions for waste oil treatment. In the field of civil engineering, waste oil is due to It is rich in oil and is used to produce concrete release agent. Concrete release agent refers to a substance applied on the construction formwork before concrete pouring, so that the formwork will not stick to the concrete surface after pouring, easy to remove the formwork, and will not affect the smoothness of the concrete surface. Its main function is to form a film on the surface of formwork and concrete to isolate the two, so it is als...
