Problems solved by technology

[0003] Since it is difficult for the ultrasonic detector to accurately measure the strength of the concrete, the core drilling method is not easy to sample, so the rebound method is often used during construction, which can more conveniently and accurately detect whether the concrete density is qualified, but the use of the rebound method A concrete rebound te

Abstract

The invention belongs to the field of engineering detection, and particularly relates to a concrete density detector for municipal engineering detection. The concrete density detector comprises a rebound apparatus, the lower portion of the outer surface of an external column is fixedly connected with the inner wall of the rebound apparatus, and a display meter is fixedly connected to the upper surface of the external column; an inner cavity of the display meter is fixedly connected with an inner cavity of the rebound apparatus through an electric wire, a lifting handle is fixedly connected to the axis of the external connection column through an open hole, and the bottom end of the lifting handle is fixedly connected with the inner cavity of the rebound apparatus through a connection column. When the device is used, a user can easily apply force to the device, different from a common rebound apparatus, the rebound apparatus part of the device is provided with four groups of test points, four groups of data can be obtained after the device is used for testing once, the average density of concrete at the position can be obtained through simple calculation of a display meter, more accurate and reliable data can be obtained, the test range is expanded, and the use is more convenient.
