Concrete sample impact resistance detection device

Abstract

The invention discloses a concrete sample impact resistance detection device, and relates to the technical field of concrete. The concrete sample impact resistance detection device comprises a bottomplate and an outer frame guard plate. A square hole is formed in the middle of the bottom plate, guide rail columns are fixedly connected to the inner top wall of the outer frame guard plate, and force application springs matched with the guide rail columns are fixedly connected to the inner top wall of the outer frame guard plate. According to the invention, by arranging the force application springs and the guide rail columns, the impact accuracy of an impact block can be ensured when the impact resistance of a concrete sample is detected, and the force application springs can ensure that the impact block obtains a relatively high speed in a relatively short distance, and therefore, the purpose of providing a large impact force under the condition that height of the device is low is achieved; and through arrangement of the square hole, when the concrete sample is impacted and crushed, fragments can directly fall into the square hole, a U-shaped protective plate can prevent the impacted fragments from splashing to injure people, a collecting box can collect the fragments, and the purpose of reducing the sweeping burden of workers is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a device for detecting the impact resistance of concrete samples. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete which is made of cement as the cementitious material, sand and stone as the aggregate; mixed with water in a certain proportion and stirred, also known as ordinary concrete, which is widely used in civil engineering. Ordinary 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, and uniformly stirred, compacted and cured. . Concrete is mainly divided into two stages and stat...
