Anti-seismic device for testing concrete compressive strength

Abstract

The invention discloses an anti-seismic device for concrete compressive strength testing. The anti-seismic device comprises a protective cover and a detection table, wherein the detection table is arranged on a base and comprises a shear fork mechanism, a lower fixing base and an upper fixing base, the lower fixing base and the upper fixing base are the same in structure, the lower fixing base isfixedly connected with the base through bolts, the upper fixing base is located over the lower fixing base and arranged oppositely, the shear fork mechanism is located between the upper fixing base and the lower fixing base, after the protective cover is closed, the detection table is positioned in an inner cavity of the protective cover. The anti-seismic device is advantaged in that a phenomenonthat broken stones splash to injure people can be effectively avoided through the protective cover, an air pump can suck out dusty air in the protective cover, and the air filter can filter the dustyair, so the dusty air is prevented from polluting the environment, the detection table has an anti-vibration function, in the vibration resistance process, the shear fork mechanism converts vibrationin the vertical direction into driving force in the horizontal direction, a spring arranged on the sliding rod in a sleeving mode consumes the driving force, and therefore the damping effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of concrete testing, and in particular relates to an anti-seismic device for testing the compressive strength of concrete. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is prepared in a certain proportion from cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary. It is a kind of artificial stone made of concrete. The concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. However, it needs to be tested in many aspects before the concrete is used. Anti-seismic device. There are some problems in the existing anti-seismic device. The specific problems are as follows: in the process of testing the concrete, gravel splashes and dust will be generated due to the impact, and the use of water spray to reduce dust will cause the...
