Concrete plastic test mold auxiliary clamp

Abstract

The invention discloses a concrete plastic test mold auxiliary clamp which comprises a magnetic base, wherein a force applying device is arranged on the top surface of the magnetic base. By matching the magnetic base, a releasing device, a locking device, a fastening device, the force applying device, a clamping device, a limiting device and a telescopic device, a plastic test mold can be fixed toa vibrating table stably. By matching the releasing device, the locking device, the fastening device, the force applying device and the clamping device, the auxiliary clamp can clamp and fix the plastic test mold from a side surface without being limited by shape and dimension of the plastic test mold, so that the auxiliary clamp is good in adaptability. By matching the clamping device and the telescopic device, the auxiliary clamp can clamp and fix the plastic test mold from the top surface, so that the auxiliary clamp is more stable, and the accuracy of a test result is improved. By matching the force applying device and the clamping device, it is convenient for an experimenter o mount and replace the plastic test mold, the test speed is increased, and the practicality of the concrete plastic test mold auxiliary clamp is improved.

Description

technical field [0001] The invention relates to the field of concrete plastic mold trial auxiliary fixtures, in particular to a concrete plastic mold trial auxiliary fixture. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, compacted and cured. In the process of research and use of concrete, it is necessary to test the compressive strength of concrete. The test data is obtained through experiments. Specifically, a cube with a side length of 150 mm is made under standard curing conditions (temperature 20 ± 2 ℃, relative humidity above 95%), cured to the age of 28d, the ultimate compressive strength measured by the standard test method is called the standard cubic compressive strength of concrete, and concrete test molds are needed in the test process. Some test ...

Problems solved by technology

[0003] In the process of concrete forming, it is necessary to put concrete into the test mold and place it on the vibrating table to vibrate. After the vibrating table is energized, the electromagnet on it is energized to generate magnetic force. The cast iron test mold can be fixed by using the magnetic force, but the plastic test mold Because the material of the mold is plastic, the electromagnet cannot attract the plastic test mold, so during the vibration process, the plastic test mold will jump violently on the vibrating table, and it is easy to fall off the vibrating table, resulting in the failure of the test, so Urgent need to design a concrete plastic mold trial auxiliary fixture
