Description

Technical Field

[0002] Lightweight ceramsite concrete wall panels are a type of lightweight aggregate concrete made of ceramsite, cement, sand, foaming agent and water, with a built-in steel grid, cast in a mold, and cured by high-pressure sterilization. It has the advantages of light weight, high strength, heat preservation, heat insulation, and sound insulation. It is suitable for non-load-bearing internal partition walls in construction projects in areas with an earthquake intensity of 8 degrees or less. Lightweight ceramsite concrete wall panels are prone to cracking when affected by improper construction, material problems, environmental factors, and load effects. In this case, it is necessary to regularly inspect and repair lightweight ceramsite concrete wall panels, and the inspection of lightweight ceramsite concrete wall panels is generally carried out using an ultrasonic detector.

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the application and with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, a lightweight ceramsite concrete wallboard crack detection device is provided, including: an ultrasonic detector 1, specifically a wall crack ultrasonic detector, which is an instrument specially used to detect cracks inside a concrete structure. It adopts ultrasonic detection technology and can quickly and accurately detect cracks inside the concrete, providing a reliable basis for structural safety assessment. A probe 2 is fixedly connected to the surface of the ultrasonic detector 1, a connecting strip 3 is fixedly connected to one side of the ultrasonic detector 1, a shell 4 is fixedly connected to the side of the connecting strip 3 away from the ultrasonic detector 1, a scale is set on the surface of the shell 4, two sets of ring buckles 8 are set on the surface of the shell 4, and the ring buckles 8 are used to place a marker pen. The shell 4 is hollow and slidably provided with two sliding blocks 6, and the two sliding blocks 6 are relative to each other. A ruler 7 is fixedly connected to each other on one side wall away from each other. The cross-section of the sliding block 6 is larger than that of the ruler 7. The sliding block 6 and the ruler 7 are arranged in a T-shape. The sliding block 6 and the ruler 7 arranged in the T-shape can be used to firmly clamp the ruler 7 inside the shell 4 to prevent the ruler 7 from falling off easily. The end of the ruler 7 away from the sliding block 6 extends to the outside of the shell 4. Sliding grooves 5 with the same shape as the ruler 7 are provided at both ends of the shell 4. Scales are provided on the ruler 7. By combining the shell 4 and the ruler 7, a telescopic ruler can be integrated on the surface of the ultrasonic detector 1, so that measurement marking can be conveniently performed without the need to prepare an additional ruler. The size can be reduced when not in use, thereby reducing the number and size of tools carried by operators and facilitating operation.

[0023] like Figure 4 As shown, one end of the ruler 7 extending to the outside of the shell 4 is fixedly connected to a support plate 12, and the height of the support plate 12 is greater than the height of the shell 4. The support plate 12 can be used to contact the wall, thereby supporting the shell 4 and the ruler 7 on both sides to prevent the shell 4 and the ruler 7 from easily tilting and distorting, thereby ensuring accurate readings.

[0024] like Figure 3 As shown, a rough layer 13 is provided on the outer side of the sliding block 6, and the rough layer 13 cooperates with the inner cavity of the housing 4. The rough layer 13 can increase the roughness of the surface of the sliding block 6, so that the sliding block 6 will slide only when it is pulled by sufficient external force, and will not slide easily, thereby ensuring the stability of the ruler 7.

[0025] like Figure 1 As shown, the diameters of the two sets of ring buckles 8 are different, and the ring buckles 8 with different diameters can be used to connect different types of markers, thereby meeting different usage scenarios and ensuring the scope of application.

[0026] like Figure 5 As shown, the connecting strip 3 further includes: a connecting sleeve 9 and a connecting strip 10. The connecting sleeve 9 is fixedly connected to the surface of the ultrasonic detector 1. The connecting strip 10 is clamped inside the connecting sleeve 9. The end of the connecting strip 10 away from the connecting sleeve 9 is fixedly connected to the shell 4. The connecting strip 10 and the connecting sleeve 9 are interference fit.

[0027] like Figure 1 As shown, a handle 11 is fixedly connected to the surface of the ultrasonic detector 1. The handle 11 is located on a side away from the connecting strip 3. The handle 11 can be used to increase the holding points of the ultrasonic detector 1, thereby facilitating people's holding operation and using.

[0028] The working principle is: when carrying the measuring device, the shell 4 and the marker pen can be connected to one side of the ultrasonic detector 1 through the connecting strip 3 composed of the connecting sleeve 9 and the connecting strip 10, so that a variety of tools can be concentrated together for easy carrying. When not needed, the concentrated tools can be removed, which is quick and convenient. When in use, the marker pen can be removed from the inside of the ring buckle 8, and then the strip ruler 7 can be pulled out from the inside of the shell 4, thereby forming a ruler for measurement marking on the surface of the ultrasonic detector 1. The marking line can be drawn using the ruler and the marker pen. The drawing tools are concentrated on the surface of the ultrasonic detector 1 as a whole, and the operator does not need to carry the drawing tools additionally. It is easy to use, can reduce the number of tools, simplify the operating steps, and improve work efficiency.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
