Abstract

A lever-type device and method for measuring the release performance of concrete. The existing concrete demoulding equipment has a complex structure, and the evaluation method is cumbersome to operate, time-consuming, laborious and expensive, and it is difficult to comprehensively evaluate the demoulding performance of concrete. The concrete and its mold of the present invention are vertically arranged on the base, the middle part of the pressure rod is hinged on the top of the column, the other end of the pressure rod is hinged with one end of the first connecting rod through a pull rod, and the other end of the first connecting rod is connected with the second connecting rod through a load cell. One end of the connecting rod is hinged, and the other end of the second connecting rod is detachably connected with the upper pressing plate or the lower pressing plate respectively; when the method of the present invention is in operation, the limit ball is first rotated so that the lower end of the second connecting rod is threaded with the upper pressing plate or the lower pressing plate respectively. Connection, the pressure rod drives the pull rod to move upward, and the pull rod pulls the upper or lower pressure plate upward through the first connecting rod, the load cell and the second connecting rod in turn, until the concrete bonded to the upper or lower pressure plate is in the concrete mold There is relative motion. The invention is used for measuring the release performance of 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...
