Metal roof multi-pressure wind resistant detection equipment

Abstract

The invention discloses metal roof multi-pressure wind resistant detection equipment. The equipment includes a box (1) with an opening upper part, the inside of the box (1) is divided into at least two parts through a partition plate (2), each separated part of the box (1) is internally equipped with a closed air bag type pressurization detection cavity (51, 52), a test piece (8) is placed at the top of the box (1) to cover and close the opening of the box (1), the test piece (8) is fixedly connected to the box (1) through a securing device, each air bag type pressurization detection cavity (51, 52) is connected to a fan (31, 32), so that external air can be sent into the air bag type pressurization detection cavities (51, 52) for pressurization respectively until the test piece (8) is burst apart by the air bag type pressurization detection cavities (51, 52), thus obtaining detection data of different parts on the test piece (8). The equipment provided by the invention can be widely applied to the field of wind resistant performance detection.

Description

technical field [0001] The invention relates to a metal roof multi-pressure wind resistance detection device. 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. Composite metal roofing systems are more and more widely used in various industries, sports, entertainment, exhibition halls, retail supermarkets and other buildings. [0003] Metal structure buildings, especially the wind resistance of metal roofs, directly affect the safety and life of the building itself, which is related to life and production. At present, there are limited means of testing metal roof systems, especially for wind pressure simulation tests and testing of metal roofs, mainly to te...

AI Technical Summary

Problems solved by technology

In fact, when the wind blows to the surface of the building, the force on the edge, eaves or ridge is greater, while the wind pressure on other areas is much smaller than the above areas, and the pressure difference between the high and low areas of the wind pressure is 1 to 3 Therefore, the existing wind resistance testing equipment cannot effectively test the real wind resistance performance of metal roofs
