Description

Measuring Assistance Apparatus for Rebound Hardness Position Marking for Structural Safety Diagnosis}

The present invention relates to a measuring aid for displaying the position of a Schmidt hardness measuring point for the safety diagnosis of a structure, and more particularly, to a number of applications applied to measuring the rebound hardness of a Schmidt hammer used for measuring the rebound hardness for the safety diagnosis of buildings, etc. It relates to a measuring aid for displaying the position of a Schmidt hardness measuring point for structure safety diagnosis, which is convenient in displaying the position of a dog's measuring point and can accurately indicate the position of the measuring point regardless of the surface condition of the measuring surface.

In general, safety diagnosis of buildings and civil structures is conducted to protect humans from disasters. is influenced by the anthropogenic factors of

Therefore, due to these factors, buildings and civil structures are often designed and built insufficiently even though they should be designed and built to sufficiently withstand slippage, settlement, applied load, wind, and earthquake, and also due to various factors, human It can also act as a safety hazard.

Therefore, in this case, safety diagnosis is performed for each item such as on-site inspection and professional overview, design criteria, basic data, etc., where technicians visit the site and investigate. It is true that it is insufficient in terms of securing safety.

Therefore, management systems and devices that professionally evaluate buildings are being developed and used, and in particular, the rebound hardness measurement method is used for safety inspection of concrete structures.

The method for measuring rebound hardness as described above uses a Schmidt hammer. In the impact test for measuring rebound hardness, deviations in measured values occur depending on whether or not the aggregate is protruded, the distance from the reinforcing bar, and the roughness of the impact surface. In order to reduce the measurement error, draw four parallel horizontal lines using chalk and a ruler at an interval of 3 cm each in the horizontal direction on the concrete surface of the measurement target, and then draw 4 horizontal lines perpendicular to the horizontal line at an interval of 3 cm each along the vertical direction. , draw 5 vertical lines, and measure the hardness inside the concrete structure by hitting the Schmidt hammer at the orthogonal points (20 points) of each horizontal and vertical line.

However, whenever the hardness of a concrete structure is measured, drawing 5 (longitudinal) × 4 (lateral) orthogonal straight lines at 3 cm intervals is very cumbersome in terms of work, relies on the operator's manual work, and takes a long time to measure. has a downside

Therefore, in recent years, in order to solve this disadvantage, Korean Patent Registration No. 10-1229305 uses stamps of a stamp type arranged at regular intervals in the horizontal and vertical directions to mark a plurality of dots on a plane at once. that has been suggested However, this technique has a disadvantage in that the measurement point can be displayed only when the surface condition of the measurement surface is good.

In addition, a sticker-type measuring point display device using an adhesive has been previously filed as Utility Model Registration No. 200224542, but it has a disadvantage that it is difficult to attach and use when the surface of the concrete structure at the measuring point is rough or dusty.
