The invention discloses a device for anti-impact detection on an enclosure system outside a building. The device comprises a pneumatic impact gun (1) with a barrel (6), an air compressor (2), a lifting seat (3) and an electric control gear (4). The lifting seat (3) is provided with a ranging laser (7) and a projection laser (8) thereon. The outlet of the barrel (6) is faced toward a test piece (9) on a test piece box (10). The ranging laser (7) measures the distance from a shell to the test piece (9) and marks a theoretical point of impact. The electric control gear (4) calculates the flight time of the shell based on the distance measured by the ranging laser (7) and the shell firing speed calculated from the set pressure of the pneumatic impact gun (1). The actual falling height of the shell is further calculated to obtain a deflection angle of the projection laser (8). The electric control gear (4) automatically adjusts the deflection angle of the projection laser (8). Laser is fired to be projected onto the test piece (9) to mark an actual point of impact. Based on the actual point of impact, the accurate positioning of the pneumatic impact gun (1) is facilitated. The accurate detection on the anti-impact performance of a random point of the test piece is realized. The device of the invention can be applied to the field of anti-impact detection on enclosure systems.
Description
technical field [0001] The invention relates to an anti-impact detection device for a building outer protection system. Background technique [0002] With the development of science and technology, various modern buildings are displayed in front of people, such as glass walls, metal packaging and so on. At present, many new buildings adopt metal structure roofing systems, especially steel structure buildings, and their roofing systems naturally also adopt metal structure roofing systems. Enclosure systems are common in various building systems, including various building metal and non-metal panels, doors and windows, roof lighting components and other exposed components used for wall or roof enclosure. [0003] The building envelope system will inevitably be impacted by foreign objects in the process of use, such as the impact of domestic sundries driven by strong winds, so it is very necessary to test its impact resistance performance. An important guarantee for safe use ...
