Description

Concrete detects resilience method measuring device
Technical Field
The invention relates to the technical field of concrete detection equipment, in particular to a concrete rebound method measuring device.
Background
The concrete is an artificial stone which is prepared by taking cement as a main cementing material, mixing with water, sand and cobble, doping chemical additives and mineral admixtures when necessary, mixing according to a proper proportion, uniformly stirring, compacting, forming, curing and hardening, and the strength and carbonization value of the concrete need to be detected after the concrete is solidified.
The rebound method is the most widely used structural concrete compressive strength detection method in China at present; the principle is that a spring-driven heavy hammer is used to strike the concrete surface by means of a striking rod, the rebound distance of the heavy hammer is measured, and the rebound value (the ratio of the rebound distance to the initial length of the spring) is used as an index related to the strength to estimate the strength of the concrete.
The carbonization of concrete refers to the process of gradually changing the original alkaline calcium hydroxide into neutral calcium carbonate under the action of carbon dioxide and water in the atmosphere, and can adopt a chemical test method, firstly, the surface of the concrete to be detected is perforated, then the inside of the hole is cleaned up, and the prepared phenolphthalein agent is smeared or dripped into the concrete, and after 1-2 minutes of the phenolphthalein agent is smeared or dripped into the concrete, the reaction is carried out, if the concrete turns red, the concrete is not carbonized; if the concrete does not change color, the concrete is carbonized, and the interface size of the carbonized and non-carbonized junction in the concrete is measured, so that the accurate carbonization depth is obtained.
The existing measuring method is that a manual hand-held resiliometer is used for detecting concrete, a measured value is manually read and recorded, then holes are drilled on the surface of the concrete manually, impurities in the holes are cleaned, phenolphthalein agent is dripped into the holes, and the interface size of the junction between carbonization and non-carbonization in the concrete is manually measured, so that the detection of the strength and the carbonization value of the concrete is realized;
however, the time is consumed by manual measurement, the measurement efficiency is lower, secondly, when the measurement point is higher, an auxiliary tool for ascending is needed to assist an inspector, and when the inspector holds the resiliometer to measure the measurement point at a high position, the body can not be balanced by holding the fixed object by two hands, and the inspector is easy to fall off from the auxiliary tool for ascending, so that certain potential safety hazards are caused, and further, due to construction reasons, impurity particles are left on the surface of concrete, and if the impurity particles are not removed, the detection result is influenced.
