Research On Building Energy-saving And Fire-resistant Window Technology

Building energy-saving and fire-resistant Window is a new type of building exterior Window,which has become one of the most important aspects in the construction of the outer protection structure.In recent years,the frequent fire of high-rise buildings threatens the safety of people's lives and property,and directly endangers the stability of the society.The National Ministry of Housing and Urban and rural construction,the State administration of quality inspection and quarantine and revised the relevant standards,in order to promote the building energy-saving and fire-resistant Window application.Building energy-saving and fire-resistanty Windows not only requirements to meet the requirements of fire resistance,but also to meet the requirements of energy-saving building Window,at present,building energy-saving and fire-resistanty Windows in the domestic still at the beginning,energy-saving and fire-resistanty Window System of the components of the subsystem has a significant impact on.Based on the analysis of the domestic and foreign research status of building energy-saving and fire-resistanty Window system,the Thermal theory of building energy-saving and fire-resistanty Window and the fire-resistant testing criterion,the paper subsystem of building energy-saving refractory Windows,The glass subsystem is simulated and analyzed by Therm and Window finite element software is used to analyze the effect of hardware deformation on the sealing performance of building energy-saving refractory Windows-and the whole Window performance of energy-saving and fire-resistanty Windows is simulated and fire-resistant experiments are carried out,which provides ideas for the design of energy-saving.Profile subsystem research.In terms of Thermal performance,the influence of the number of cavity and cavity structure on the Thermal performance of building energy-saving refractory Windows is analyzed by Therm software.The profile series determines,the Window type size is certain,increasing the number of profile cavities will not affect the Thermal performance of building energy-saving and fire-resistanty Windows;The change of the shape cavity structure will cause the change of the relative position between the frame and the glass,and the change of the position of the insulating strip and the glass will cause the change of the isotherm.Fire resistance,the aluminum alloy profile itself does not have fire-resistant properties,and it is difficult to process the aluminum alloy profile surface to meet the fire resistance requirements,it is usually in the aluminum alloy profile cavity filled with refractory and Thermal insulation of the expanded graphite base materials to achieve the purpose of fire-resistant profiles.Glass subsystem Research.Using Window software to simulate and calculate the different kinds of fireproof insulating glass,the Thermal performance of two glass single chamber fireproof glass and three glass two-chamber fireproof Glass are simulated and calculated with the K value of insulating glass.The fire performance of two kinds of glass is analyzed and compared,we find that three glass two cavities fireproof glass containing monolithic fireproof glass The Thermal performance is much higher than the two glass single cavity fireproof glass containing composite fireproof glass.Sealing subsystem Research.The influence of the locking device and the hinge on the deformation performance of the Casement window is analyzed by the finite element software.The greater the number of lock-closed points,the more uniform the position distribution,the smaller the deformation of the doors and windows under the action of wind load;hinge installation number and location of the sash to the drop of the influence,according to the size of the sash correct choice of hinge specifications and quantity,and reasonable layout hinge position to reduce the gravity of the window sash subsidence,when the Flat open window to install two hinge,it is recommended to open the door and window hinge installation,two hinge installed in the distance close to the top and below the window frame,the installation of three hinge,the proposal to open doors and windows Hinge installation,the middle hinge installed in the distance from the top hinge 1/4 At the same time,the gap seal of the building energy-saving refractory window needs to be sealed in three parts,the seal between the window frame and the wall,the seal between the window frame and the sash,the seal between the glass and the window frame fan.Research on the whole Window performance.The Therm and Window software are used to simulate and analyze the whole Window Thermal performance of the design scheme,and the fire Resistance experiment of the Window products and the design of energy-saving fireproof Windows are provided.
