Description

A device for rapidly and accurately arranging survey areas and survey points

technical field

The utility model relates to the field of construction, in particular to a device for auxiliary arrangement of measuring points and measuring areas when testing the strength of concrete.

Background technique

In the field of construction, non-destructive testing of concrete compressive strength is an important indicator when testing building structures or components. When testing the compressive strength of concrete, the commonly used methods are the rebound method and the ultrasonic method. No matter which method is used, the layout of the measuring area and measuring points needs to be carried out according to the building structure or components to meet the non-destructive testing standards for concrete strength. requirements. However, up to now, in the non-destructive testing of concrete, no special equipment and devices have been proposed for the layout of the measuring area and measuring points. In actual work, the operators need to use a variety of simple tools such as elastic wires, tape measures, and rulers, and cooperate with multiple people to complete the layout of the measurement area and measurement points. It is time-consuming and labor-intensive to draw the measurement area and point map; and when drawing the measurement area and point map, it is often impossible to ensure that the corresponding measurement areas of the two relative test surfaces are on the same horizontal line or/and vertical line, resulting in the use of a ruler for measurement There is a certain error (slightly larger) in the value of the test distance between the two relative measurement intervals, which makes the measured ultrasonic velocity value too fast, and the estimated concrete strength value is too large, which affects the accuracy of the test.
