Abstract

The invention discloses a concrete compactness detection device, which comprises a ring body composed of a first semi-ring and a second semi-ring which have the same structure, and an adjusting seat connecting the first semi-ring and the second semi-ring; the fixing seat comprises a seat body and a seat stand arranged on the seat body, one end of the seat body is hinged to the other end of the first half ring, and the other end of the seat body is hinged to the other end of the second half ring; the knocking device is arranged on the seat stand, the knocking device comprises a swinging hammer and a driving mechanism for controlling the swinging hammer to swing, and the swinging hammer is used for knocking concrete needing to be detected; the measuring device is arranged on the ring body and used for collecting sound generated when the knocking device knocks the concrete, and the measuring device comprises a plurality of sound sensors and a displayer connected with the sound sensors; wherein one end of the first half ring is connected with the adjusting seat in a hinged mode, and one end of the second half ring is detachably connected with the adjusting seat.

Description

technical field [0001] The invention belongs to a building construction detection device, and in particular relates to a detection device and a detection method of concrete compactness. Background technique [0002] In actual engineering construction, the quality of concrete has a pivotal impact on the quality of the entire project. The hardened concrete should have sufficient strength and durability indicators to bear the load and resist the erosion of the environment. This important indicator is the density of the concrete. The density of concrete refers to the proportion of the volume of the solid material part of the concrete to the total volume, indicating the degree of filling of the solid material in the concrete volume, that is, reflecting the density of the concrete. The better the overall performance. [0003] At present, there are generally three common methods for testing the compactness of CFST columns: [0004] 1. Core drilling method, that is, drilling cores...

Problems solved by technology

This method is costly and is seriously affected by the construction environment, so it is theoretically strong but not very feasible in the actual construction process

[0006] 3. The percussion method, which is suitable for the general survey of the concrete quality of the column core, depends entirely on the technology and experience of the technicians, and is greatly affected by subjective factors; and the percussion method lacks theoretical basis and data for archiving, which is not convenient for construction technology management and quality inspection technology management; in addition, for concrete-filled steel pipe columns with large wall thickness, it is difficult to make accurate judgments by the percussion method

[0008] The present invention is provided with a movable ring that can be deployed, and is connected by a connecting structure that can be quickly installed and disassembled to ensure that it forms a circular ring and is installed on the outside of the steel pipe concrete column, which is convenient for installation and use of the device; The pressure of the concrete column enables the device to be supported, thereby avoiding the device from falling and making it safer to use. However, the above-mentioned device still has the problem of insufficient installation stability during use. Simply relying on the compression piece to fix it will easily lead to unstable fixation, making the device fall to the ground. The end where the impact hammer is located is inclined, and the use of the impact hammer requires manual lifting, which is not accurate enough, time-consuming and laborious, and still needs to be strengthened
