Description
Technical Field
The invention belongs to the technical field of building external windows and fireproof windows, and particularly relates to an ultralow-energy-consumption heat-insulation fireproof window and application thereof.
Background
Windows used in buildings are classified into different kinds according to functions, such as fire windows, exterior windows of buildings, etc. These differently acting windows tend to vary widely in technical requirements and even conflict.
For example, according to the requirements of GB/T31433-2015 general technical conditions for building curtain walls and doors and windows, the qualified building outer window is required to have certain wind pressure resistance, airtight performance, watertight performance, heat insulation performance and air sound insulation performance.
The existing common building external window adopts a broken bridge aluminum window. The broken bridge aluminum window is light and handy, can lighten the bearing capacity of the building outer wall and hardware, has excellent heat preservation performance, but has poor fire resistance.
Because the bridge cut-off aluminum window uses not only a large amount of aluminum alloy, which is not fire-resistant, but also inside it inevitably requires hard plastic as a connecting member, and the hard plastic used also needs to be plastic of low thermal conductivity but inflammable, such as nylon.
0008.
For another example, according to the requirements of GB 16009-2008 fire protection window, qualified fire protection window needs to have excellent wind pressure resistance, air tightness and fire resistance. Fire protection windows are generally classified as insulating fire protection windows (class a) and non-insulating fire protection windows (class C) according to their performance. The window frame and the window sashes of the heat-insulating fireproof window are made of steel materials which are not easy to burn, and the fireproof glass of the heat-insulating fireproof window is made of multi-layer composite fireproof glass. The multi-layer composite fireproof glass is formed by stacking low-radiation glass, argon gas separation chamber, ultra-white glass, fireproof liquid and ultra-white glass in a laminated mode, and has excellent fireproof performance, but poor light transmittance, the overall thickness of the glass reaches more than 60mm, and due to the fact that the overall thickness of the glass reaches more than 60mm, due to the fact that the steel window frame is provided with the window frame and the window sash, the fireproof window is heavy.
This makes current insulated fire protection windows mainly used for indoor fire separation or fire doors, but not for building exterior windows. Firstly, because the fire window is not required to have watertight performance and thermal insulation performance in the related national standard, secondly, because the self weight of the thermal insulation fire window is based on, the hardware matched with the fire window is not required to bear the weight of glass for a long time, and the outer wall of a building is not required to bear the weight of the whole fire window for a long time, so that the fire glass or the fire window is easy to fall off wholly, and the safety is poor.
Meanwhile, as the contradiction between energy and environment is increasingly prominent, the total energy consumption and the uplink pressure of the energy consumption intensity of the building are continuously increased, the energy efficiency level of the building is continuously improved, and the method is a necessary choice for implementing green development in most cities.
From a worldwide perspective, ultra-low energy consumption buildings are becoming a trend of building energy conservation. The ultra-low energy consumption building is an emerging modern building, and the heat exchange between the interior and the exterior of the building is interrupted by utilizing the passive heat insulation structure of the building, so that the energy consumption for refrigerating and heating in the building is greatly reduced.
In order to establish an ultra-low energy consumption building system adapting to characteristics of summer hot and winter cold areas in China, the demonstration application of the ultra-low energy consumption building in the summer hot and winter cold areas in China is better guided, and residences in Shanghai and urban and rural construction management members specially make "Shanghai ultra-low energy consumption building technology guidance (trial run) in Shanghai" in 2019 (hereinafter referred to as "guidance").
The guide rule has higher technical requirements on performance indexes of the ultra-low energy consumption building exterior window, such as sun shading coefficient, visible light transmittance, heat transfer coefficient and the like.

The cross section of the shape maintaining insert core is U-shaped with an opening facing the outside, and the shape maintaining insert core is filled with the first fireproof expansion sealing strip 14. The form-maintaining insert is not blocked in front of the first fire-protecting intumescent seal 14, but the first fire-protecting intumescent seal 14 is exposed to the open flame on the straight side, thereby exerting its function, and at the same time, the form-maintaining insert is exposed to the open flame later than the last line of defense.

The glass restraint strap is further provided with a clamping jaw integrally formed with the glass restraint strap, wherein the clamping jaw is used for clamping the heat-insulating fireproof glass 3, so that the heat-insulating fireproof glass 3 is prevented from falling down after the window sash 2 is burnt, and one clamping jaw is generally required to be arranged on the indoor side and the outdoor side of the heat-insulating fireproof glass 3.
The glass support bottom block is arranged at the bottom of the heat-insulating fireproof glass 3, the glass support bottom block is a hard block made of a fireproof material which is not pulverized after being burned, and the glass support bottom block is in direct contact with the bottom of the heat-insulating fireproof glass 3 and is in contact with the wall plate of the form maintaining inserting core, wherein only one layer of wall plate of the window sash 2 is arranged between the glass support bottom block and the form maintaining inserting core. The glass backing block must be hard and not sintered to avoid bursting of the insulating fire-resistant glass 3 by falling into contact with metal.
As an alternative embodiment of the invention, the first fire-resistant intumescent weather strip 14 may be replaced by a fire-resistant potting compound. The fireproof filling material is a filler with heat insulation effect and capable of absorbing a large amount of heat, can keep the window frame 1 and the window sash 2 from yielding or melting in a short time, has the effect of caulking and sealing, and is used for prolonging the time required for burning the window frame 1 and the window sash 2 and preventing heat from being transferred into a room.
