Description

Technical Field

[0002] The main structure of a building refers to a plane or space system that is connected by several components and can withstand the impact in a house. It is an organic system based on the foundation, accepting, bearing and transmitting all the upper loads of the construction project, and maintaining the integrity, stability and safety of the upper structure. In short, the main structure of a building is the skeleton of the building, bearing the weight and stability of the building.

[0003] In addition, depending on the structural form of the building, the main structure of the building may also include wall panels, shear walls, frame columns, frame beams, concrete walls and other components. These components are interconnected to form an organically connected system as a whole, jointly bearing various loads of the building to ensure the stability and safety of the building. In construction projects, the construction quality of the main structure of the building is directly related to the safety, stability and service life of the building. Therefore, during the construction process, the construction and inspection of the main structure must be carried out in strict accordance with the design requirements and specifications to ensure that the construction quality of the main structure meets the standards and requirements.

[0004] With people's attention to engineering quality, as well as the rapid development and maturity of non-destructive testing technology, the application of non-destructive testing technology in construction projects has increased.

It can be said that it has its place in the construction, acceptance and use of projects. Application number: CN202122561351.8, provides a bearing strength identification and detection device for the main structure of a building, which replaces the tester's hand-pressing of the rebound tester by pressing the component on the rebound tester. It only needs to turn the drive wheel, which is easy to operate.

[0026] The rotation of the output end of the first motor 35 drives the rotation of the rotating screw 33, and then drives the lifting frame 34 to rise or fall, which can meet the measurement requirements of different height positions.

[0027] A first motor 35 for driving the rotating screw 33 to rotate is provided at the bottom of the inner wall of the placement box 31.
