Concrete detection rebound method measuring area seal device

Abstract

The invention discloses a concrete detection and rebound method area measuring seal device, which comprises a square bottom plate and a square hollow frame, and a 4*4 seal grid is fixed inside the hollow frame, wherein the side length of the seal grid inside the hollow frame is 240mm And each grid size is 60*60mm, the four corners of the hollow frame are provided with installation through holes and the frame thickness of the hollow frame is 5mm, and the front of the bottom plate is provided with the internal seal of the central control frame The grids correspond to 4*4 mounting slots one by one, and a rotating motor is installed inside each of the mounting slots, and a circular grinding disc is fixedly connected to the output end of the rotating motor. The stamp can not only perform pre-grinding operations on the survey area, but also perform rapid stamping operations on the survey area, which is convenient for inspectors to quickly draw survey areas at different heights to ensure the safety and health of inspectors.

Description

technical field [0001] The invention relates to the technical field of concrete performance detection equipment, and more specifically, relates to a concrete detection rebound method measurement area stamp device. Background technique [0002] The rebound method to detect the compressive strength of concrete is the most widely used method in the on-site inspection of concrete structures in my country. The relevant technical regulations stipulate that when random testing is performed on concrete components in batches, the number of random inspections should not be less than 30% of the total number of components in the same batch , and should not be less than 10 pieces; for general components, the number of measurement areas for each component should not be less than 10; each measurement area should read 16 rebound values, and 16 measurement points are required to be in the measurement area of ​​0.04 square meters Evenly distributed within the range, the size of the survey area ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned prior art detection equipment has the following disadvantages: due to the large number of measurement areas, the grid drawing method is very cumbersome, time-consuming, and the work intensity of the detection personnel is high; many detection tasks will be performed at high places on the construction site (generally 3-5 meters) ), it is not only difficult to operate when drawing lines, but also has certain potential safety hazards; in addition, the wall surface of the measurement area is not smooth, and the bottom surface such as loose layer and laitance is prone to appear, which will affect the later detection results. Grinding discs smooth the wall, but the work efficiency is low in the whole process, and a large amount of dust will be generated, which will affect the health of the construction workers. In addition, for the survey area map, it is necessary to reserve 200-500mm from the corners of the surrounding areas. distance, the existing drawing tools are inconvenient to accurately control the distance
