Abstract

The invention discloses a device for testing the fireproof performance of an external facade of a building. The device comprises a simulation main wall with a window in the lower part, a combustion chamber, a combustor assembly arranged inside the combustion chamber, simulation wing walls arranged at two sides of the simulation main wall, a net rack arranged in a space formed by the simulation main wall and the two simulation wing walls, a heat flux sensor for measuring the intensity of heat flux, a thermocouple sensor hole site for measuring the temperature, and an environmental wind supply device located in front of the two simulation wing walls, wherein the combustion chamber is arranged beside the simulation main wall and is provided with an opening communicating with the window; and the heat flux sensor and the thermocouple sensor hole site are arranged on the net rack. The device is a simulation test device for the fireproof performance of the external facade of the building in different environmental wind speed environments for different forms of the external facades of high-rise or super high-rise buildings. Compared with the prior art, the device has the advantages that important test models can be provided for the coupling action influences of external facades forms of the buildings and the external environmental wind speeds on open overflow flame characteristics and the influences on the fireproof performance of the external facade, and the bank in the industry is filled.

Description

technical field

[0001] The invention relates to the technical field of fire protection engineering, in particular to a test device for the fire performance of building facades. Background technique

[0002] With the continuous development of my country's economy, high-rise / super high-rise buildings continue to emerge, and their fire safety issues are also increasingly valued. After a fire breaks out in a high-rise / ultra-high-rise building, the incompletely combusted components of the fuel form overflow flames through the vertical openings of the external wall such as windows, which is likely to ignite the combustible thermal insulation materials on the external wall, or cause the upper glass curtain wall to rupture, thus causing multiple accidents. Floor fire spread. Many fire accidents at home and abroad in recent years have shown that it is difficult to put out fires in high-rise buildings, and it is difficult to quickly control the fire, which can easily lead to heavy pr...

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0034] Such as Figure 1-6As shown, the present invention provides a kind of simulated test device related to different environmental wind speeds, different high-rise and super high-rise building facade structure form fire performance tests, which includes simulated main wall 1, simulated wing wall 2, combustion chamber 3, net Frame 5, regulating mechanism. A window 6 is opened at the lower part of the simulated main wall 1 , and the combustion chamber 3 is arranged beside the simulated main wall 1 , and an opening communicating with the window 6 is provided on it. The combustion chamber 2 is used for simulating combustion, so that a flame is generated and overflows to the simulated main wall 1 through the window 6 . Specifically, a burner assembly is provided...
