Metal building element dynamic wind load simulation test device

Abstract

The invention discloses a metal building element dynamic wind load simulation test device. The simulation test device comprises an upper box body(1), a lower box body(2), a seal element (3), a fan (4), a reversal valve(5), a flutter valve (6), a regulating valve (7) and a control device, wherein a reversing device (500) is arranged in the reversal valve(5), the reversal valve(5) comprises a valveair inlet, a valve air outlet, a first valve air inlet and air outlet and a second valve air inlet and air outlet, the air outlet of the fan (4) is communicated with the valve air inlet, the air outlet thereof is communicated with the valve air outlet, the second valve air inlet and air outlet are communicated with the upper box body(1), when the reversing device (500) is in a first reversing state, the valve air inlet is communicated with the first valve air inlet and air outlet and the valve air outlet is communicated with the second valve air inlet and air outlet; and when the reversing device (500) is in a second reversing state, the valve air inlet is communicated with the second valve air inlet and air outlet and the valve air outlet is communicated with the first valve air inlet and air outlet. The simulation test device of the invention can be used in the detection field of metal curtain walls and roofs.

Description

technical field [0001] The invention relates to a dynamic wind load simulation test device for metal building components. 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. At present, the existing metal roof system of this kind of buildings usually adopts metal roof panels with internal support and fixing structures to obtain beautiful and stable use requirements; by setting various internal support fixings and various fasteners, it can also obtain There is a flexible placement space between ...

AI Technical Summary

Problems solved by technology

At present, domestic testing methods for metal roofing systems are limited, especially large-scale equipment is mainly used for wind pressure simulation tests and testing of metal roofing, and the performance indicators of the roof panels are mainly tested, and the test specimens required for testing are large in size, such as A test piece of 7.5m×2.5m is required for testing. Not only is the equipment complex, the investment is high, the cost is high, and the floor area is large, but the detection work cycle is long, the efficiency is not high, and the simulation and detection effect of the anti-fluctuation wind pressure is not good. it is good
