Technical Field
The invention relates to a metal roof multi-pressure wind-resistant detection device.
Background
With the development of science and technology, various modern buildings are displayed in front of people, such as glass walls, metal body packages and the like. At present, many new buildings adopt a roofing system with a metal structure, especially a steel structure building, and the roofing system naturally also adopts the roofing system with the metal structure. Composite metal roofing systems are becoming more and more widely used in various industrial, sports, entertainment, exhibition halls, retail supermarkets and other buildings.
The wind resistance of a building with a metal structure, particularly a metal roof, directly influences the safety and the service life of the building, and the life and the production are concerned. At present, the means for detecting a metal roof system is limited, particularly, a wind pressure resistant simulation test and detection are carried out on a metal roof, and the performance index of the whole roof panel is mainly tested under the same pressure. In fact, when wind blows to the building surface, the stress on the edge, eave or ridge is large, the wind pressure borne by other areas is far smaller than that in the areas, and the pressure difference of the high and low areas of the wind pressure is 1-3 times, so that the existing wind resistance detection equipment cannot effectively detect the real wind resistance of the metal roof.

The technical scheme adopted by the invention is as follows: the detection device comprises a box body with an open upper part, the box body is divided into at least two parts by a partition plate, closed air bag type pressurization detection cavities are arranged in each divided part of the box body, a detection test piece is placed at the top of the box body to cover and close the open part of the box body, the detection test piece is fixedly connected with the box body through a locking device, each air bag type pressurization detection cavity is connected with a fan, so that outside air is sent into each air bag type pressurization detection cavity to be pressurized respectively until the detection test piece is broken by the air bag type pressurization detection cavities, and detection data of different parts of the detection test piece are obtained.
And air valve adjusting assemblies are arranged between the fans and the box body to independently control the pressure in the air bag type pressurization detection cavities, so that different testing pressures are applied to different parts of the detection test piece.
The air bag type pressurization detection cavity is covered by a plastic film to form an air bag.
The detection test piece is a metal roof panel.
The box body is matched with the size of the detection test piece.
The invention has the beneficial effects that: the invention comprises a box body with an open upper part, the box body is divided into at least two parts by a partition board, closed air bag type pressurization detection cavities are arranged in each part of the box body, a detection test piece is placed at the top of the box body to cover and close the open part of the box body, the detection test piece is fixedly connected with the box body through a locking device, and each air bag type pressurization detection cavity is connected with a fan so as to send outside air into each air bag type pressurization detection cavity to be respectively pressurized until the detection test piece is broken by the air bag type pressurization detection cavity, so that detection data of different parts of the detection test piece are obtained; the invention overcomes the defects of the prior art, at least two air bags are formed by at least two closed air bag type pressurization detection cavities which are separated, at least two fans are respectively and independently driven to respectively generate different pressure values, and the air bags act on the same test piece, so that the real wind pressure condition of the metal roof can be effectively simulated.
