Technical field

The present invention relates to external true environment wind to act on the heated fire spread behavior of lower typical building heat preservation plate material and building A kind of technical field of alien invasion structure design, and in particular to Architecture Outer Curtain Wall/wall coupling arrangement under the conditions of variable environment wind Heat preservation plate material Spread Characteristics test device.

Background technique

Since the 21th century, energy problem has become one of the principal element for restricting social sustainable development.It is adjoint China's new building quantity is significantly increased, and building trade carries out energy conservation comprehensively.A large amount of high molecular polymer thermal insulation materials, example Such as: hard polyaminoester (Rigid polyurethane, RPU), extruded polystyrene (Extruded polystyrene, XPS) With the cystosepiments such as molded polystyrene (Expand polystyrene, EPS) because its superior thermal and insulating performance is extensive Applied in modern architecture wall.But since these high molecular polymer thermal insulation materials usually itself have combustibility.Once Construction wall sag of protecting coating or breakage, the thermal insulation material in interlayer can be ignited rapidly after encountering open fire, to generate fire Sprawling behavior, formed the three-dimensional burning of large area, and can be generated in combustion process a large amount of poison gas cause life danger and Property loss generates great social danger and influence.The many fire disaster accidents occurred in recent years such as on 2 9th, 2009 The Shanghai teacher apartment that Harbin " longitude and latitude 360 " Gemini mansion fire disaster accident of generation, on November 15th, 2010 occur London high-rise apartment building building " Glan Fei Erta " fire disaster accident that fire disaster accident and on June 14th, 2017 occur.It is above-mentioned The generation of accident is all because construction wall heat preservation is wiped caused by expecting to be ignited.The design of modern architecture space abnormity More and more common, outer enclosed structure of the curtain wall as building directly influences the expression of building visual effect.Building body wall Except not only have outer window system, while also having glass curtain wall, stone curtain wall, ceramic plate curtain wall, metal curtain wall and wood-based plate curtain wall concurrently Equal curtain wall systems.So that there are many complicated outer curtain wall/wall coupling arrangements in building.Outer curtain wall/wall coupling arrangement Presence the fire spread behavior of wall heat insulation material will be made more complicated.Firstly, since routine building curtain wall is encapsulated and is built It builds except main structure, once wall heat insulation material is ignited, the presence of outer curtain wall becomes " protection face " of fire, it will resistance Hinder and increase the difficulty of fire-fighting fire extinguishing rescue.Become secondly, there is certain irregular annular between building curtain wall and wall body structure Cross section air interlayer space, so that the vertical long and narrow vent passages that outer curtain wall/wall coupling arrangement is dangerous.Along with wall The development of the body thermal insulation material middle and later periods intensity of a fire, high-temperature flue gas will accumulate flowing in outer curtain wall/wall configuration interlayer space, and Interaction feedback is formed with fire spread behavior.It is strong to will finally change the fire spread developing characteristics of wall heat insulation material, Thermal feedback Degree, plume turbulence structure, smoke-filling movement and flow field, flue gas product and its transport rule.
