Description

Technical Field

[0001] This invention relates to the technical field of health status testing of timber structures, and in particular to a method and equipment for testing the health status of timber structures. Background Technology

[0002] During use, timber structures require regular health checks to ensure their safety. Most existing testing methods involve destructive methods such as bending or compressing the timber structure. For example, a timber strength testing device proposed in the authorized patent application CN202120904940.9, while effective in detecting the health of timber structures, causes significant damage. Another method uses ultrasound to detect the health of timber structures, such as the ultrasonic non-destructive testing equipment for timber proposed in the authorized patent application CN202022103209.4. While this avoids damage, the density of different types of wood varies, requiring comparison of the detected data with other data to arrive at the final result. This process is time-consuming and labor-intensive, resulting in poor practicality. Therefore, improvements to existing equipment are needed. Summary of the Invention

5. A timber condition detection apparatus as claimed in claim 4, wherein, The detection device includes a third electric cylinder (21), a spring (22) and a high-definition camera (23). The third electric cylinder (21) is installed at the front end of the arc-shaped clamp (4) on the front side, and the rear end of the third electric cylinder (21) passes through the arc-shaped clamp (4) on the front side. The front end of the high-definition camera (23) is connected to the rear end of the third electric cylinder (21) through the spring (22), and a supplementary light is provided on the high-definition camera (23).

6. A timber condition detection apparatus as claimed in claim 5, wherein, The thermal imaging device includes a display screen (24), a thermal imaging monitor (25), and a connecting cable (26). The bottom end of the display screen (24) is rotatably mounted on the top of the housing (9), and the bottom end of the thermal imaging monitor (25) is connected to the battery (14) via the connecting cable (26).

7. A timber condition detection apparatus as claimed in claim 6, wherein A method for detecting the health status of timber structures using timber structure health status testing equipment includes the following steps: Step 1: Wipe the surface of the wooden structure to remove dust. Step 2: Attach the high-definition camera (23) to the surface of the wooden structure, take a high-definition video of the surface of the wooden structure through the high-definition camera (23), and display the video on the display screen (24) so ​​that the staff can observe the cracks on the surface of the wooden structure. Step 3: The two sets of arc-shaped clamps (4) are closed and fitted onto the wooden structure, and air is injected into the pressurizing device to seal the top and bottom of the two sets of arc-shaped clamps (4), so that a closed space is formed between the two sets of arc-shaped clamps (4); Step 4: Inflate the two sets of curved plates (4) with air, and at the same time detect the air pressure changes in the two sets of curved plates (4) to detect the air permeability and looseness of the wood structure. At the same time, use a thermal imaging monitor (25) to detect the temperature changes around the two sets of curved plates (4) to find the location of gas leakage around the two sets of curved plates (4). Display the air pressure detection results and temperature change images on the display screen (24) so ​​that the staff can detect the health status of the wood structure by observing the cracks on the wood structure, the air pressure changes in the two sets of curved plates (4), and the location and direction of hot gas leakage.
