Description

Technical Field

[0001] The utility model relates to the field of building exterior decoration, and more specifically to a metal profiled plate rib clamp pulling force detection device. Background Art

[0002] At present, in the exterior decoration of large-scale venues, exhibition halls and other public buildings, the roofs mostly use metal corrugated plate systems, and metal clamps are set on the ribs of the metal plates. Various types of outer panels, such as decorative panels or solar photovoltaic panels, can be installed on the clamps to meet the building appearance or power generation needs.

[0003] After the outer layer is installed, the wind suction force on the roof will be transmitted to the metal clamp through the outer layer of the roof, and then transmitted to the metal corrugated sheet system below through the metal clamp. The clamp and the metal corrugated sheet of the roof resist the upward pulling force transmitted by the outer layer through the clamping force of the clamp and the friction between the two. However, there is currently a lack of mechanical calculation formulas in this regard. Most tests are conducted using experimental methods, and the test values ​​are obtained before application. However, since there is no unified standard for the test method, it cannot truly reflect the actual mechanical properties of the clamp under different layout conditions. Therefore, there will be a large deviation in the test results, which will pose a hidden danger to engineering applications. Utility Model Content
