Based On The Architectural Design To Discuss The Residential Building Facade Of The Fire Spread The Vertical

At present, researchers and specifications were usually pay attention to designing non-combustible performance of building external wall thermal insulation material to protect fire on residential building fa?ade. However, the view of fire protection from the architectural design itself was few and far between.This article put forward the method of architecture design and integration of the design elements of the fa?ade to prevent fire spreading without depending on the premise of non combustible insulation materials. Main work and conclusions are as follows:(1) By means of numerical simulation software FDS to simulates and analyzes theinfluence of different form of residential flat on building facade fire spreading. Thecomparison of temperature, velocity and CO concentration is used to illustrate theeffect of L plane form and grooves flat form on the building fa?ade. Standard flatform(rectangular plane) is compared to observe whether it can prevents or slowsfire spreading on residential building facade. Moreover, the article comparestemperature, velocity and CO concentration of fire spreading and researches theinfluence on fire spreading by changing the depth or wide of groove type plane.(2) The FDS was used to compares the temperature, velocity and CO concentration inordinary window and the bay window when fire spreading on residential buildingfa?ade. FDS was used to simulate the three types of bay window: the first typewas fixed the eave under the window had 400 mm distance between the wall whilechange the distance between the eave on the window and the wall in 500 mm,600mm, 700 mm respectively. The second type was fixed the eave on the windowhas 400 mm distance between the wall while change the distance between the eaveunder the window and the wall in 500 mm, 600 mm, 700 mm respectively. The thirdtype was both change the distance between the eave on the window and the wallas well as the eave under the window and the wall in 500 mm, 600 mm, 700mmrespectively. The three types were used to compare the temperature, velocity andCO concentration in firing and concluded their effects to fire spreading. What’smore, by comparing the temperature, velocity and CO concentration, FDSsimulated the different rate between the height of the bay window and the heightof the windowsill wall and the different rate between the width of bay window and the width of wall between window, and analyzed their effect on fire spreading on residential building fa?ade.Rectangular plane form of housing construction is chose as an example. The article integrates the design of bay window, balcony and fire overhangs and puts forward the opinion that architectural design methods can effectively block or slow down the fire spreading on residential building fa?ade.
