Description
Technical Field
The invention belongs to the technical field of fireproof windows, and particularly relates to a heat-insulation fireproof window.
Background
Along with the rapid development of modern city construction, the requirements on fire prevention, heat preservation and the like of buildings are more and more emphasized, particularly, the density of buildings in modern cities is high, the fire resistance of the buildings is an important aspect for guaranteeing personal safety, and the national standards GB50016-2014 'fire standards for building design' and GB16809-2008 'fire windows' are specified in detail in the aspect of fire windows. Meanwhile, the window is used as an external connection outlet of a building and is one of building structures with the largest heat dissipation, and particularly, the window has a large indoor and outdoor temperature difference in winter in China, so that the window is required to have good heat insulation performance while being fireproof. On the other hand, the temperature difference between the indoor and outdoor sides or the temperature difference between day and night can cause the metal frame of the window to expand with heat and contract with cold to generate deformation or gaps, which requires the sealing part of the window to have good compression-resistant recovery and elastic deformation capacity.
At present, the qualified fire windows generally adopt steel materials, and the steel has higher strength, hardness and melting point, and has better fire resistance, water resistance, air tightness and wind pressure resistance. However, steel fire windows also have some disadvantages: (1) the steel has a large heat conductivity coefficient, is not beneficial to indoor heat preservation of the window, has poor compression resistance recovery and elastic deformation performance although a sealing part is added, particularly has large indoor and outdoor temperature difference in northern areas, and has unsatisfactory heat preservation performance of the steel window; (2) the corrosion resistance of the steel is poor, and the steel is easily affected by condensation and frosting after being exposed in indoor and outdoor environments for a long time; (3) the steel surface color is darker and has irregular texture, can plate one deck zinc on the steel surface usually, elegant appearance, however after steel welding is polished, the zinc layer on surface can have wearing and tearing of different degree, influences outward appearance pleasing to the eye and corrosion resisting property.
In the aspect of improving the heat conductivity coefficient and the heat insulation performance of a window, scientific research technicians carry out more work, and a special space is reserved in a window frame or a vertical column for fixing glass and is used for filling a fireproof heat insulation material. For example, patent CN201811111147.2 discloses a bridge cut-off aluminum alloy heat preservation fireproof window, including bridge cut-off aluminum alloy framework and the double glazing that sets up in its inside, the double glazing middle part is equipped with the vacuum cavity, double glazing's side is equipped with the mounting groove, is equipped with the refractory material layer in the mounting groove, and the both sides wall of aluminum alloy framework is equipped with the pouring recess that is used for pouring polyurethane insulation material, and the refractory material layer can prevent fires, and intensity is than higher again, and its connection is stable, is difficult for droing, and this bridge cut-off aluminum alloy heat preservation fireproof window's thermal insulation performance is.
Patent CN201620059117.1 provides an energy-conserving heat preservation section bar and including the energy-conserving heat preservation fire window of this section bar, and this energy-conserving heat preservation section bar is made by inorganic fiber reinforced resin, and inorganic fiber reinforced resin is formed by inorganic fiber and resin complex, is equipped with the cavity on energy-conserving heat preservation section bar, and is equipped with one or more fire prevention inflation strips on the inner wall of cavity. This energy-conserving heat preservation fire window includes: window frame, casement, fire prevention glass and fire prevention core, fire prevention core is made by energy-conserving heat preservation section bar. The energy-saving heat-preservation fireproof window is high in safety performance, has good sound insulation, heat insulation and heat preservation performance, and meets the door and window energy-saving requirements of various places on building energy conservation.
At present, although the heat-insulating fireproof materials filled in the fireproof window frame are various in types, the existing industrial or natural materials are basically selected, and no sealing heat-insulating material with excellent compression-resistant recovery and elastic deformation performance is used in the regions with very low temperature or great day-night temperature difference in China, so that the fireproof window has tiny gaps due to the deformation of the metal frame during expansion with heat and contraction with cold, and the heat-insulating performance of the fireproof window is seriously influenced.
