Description

Technical Field

[0001] The utility model relates to the technical field of glass windows, in particular to a fireproof window. Background Art

[0002] Fireproof windows are a type of fireproof isolation equipment with good fireproofing and sound insulation properties. Their main function is to prevent the fire from spreading to other rooms after a fire occurs. Since fireproof windows are made of fire-resistant materials, they have high fireproofing properties and can effectively seal the fireproof area, blocking the spread of fire and smoke, thereby ensuring the safety of people and property; at the same time, they can effectively isolate harmful gases and smoke to ensure the safety of people's escape; the use of fireproof windows can effectively improve the fire safety level of the building, meet the fire protection requirements of the building, and cooperate with other fire protection facilities to form a complete fireproof isolation system. The application of fireproof windows can effectively prevent fires and combustion accidents, reduce the incidence of disasters and the losses caused by secondary disasters.

[0003] Fireproof windows are an important component of clean rooms. Their main function is to prevent the fire from spreading to other rooms after a fire occurs. At present, the wall panels in clean areas generally use special color-coated steel sandwich panels. The fireproof windows themselves must not only play an observation role, but also have corresponding fire resistance. However, the current fireproof windows are mainly composed of fireproof glass and metal frames. The main purpose of the design is to prevent the spread of flames when a fire occurs and ensure the safe evacuation of personnel. The fireproof glass used is mainly single-layer or multi-layer composite glass. These glasses can resist flames for a certain period of time, but do not have good thermal insulation properties and smoke exhaust effects.

[0004] Based on the above situation, we propose a fireproof window to solve the above problems. Utility Model Content

[0005] The utility model provides a fireproof viewing window to solve the problem in the prior art that the fireproof viewing window only prevents fire but does not insulate heat or prevent smoke exhaust.

[0006] The technical problem solved by the present invention is achieved by the following technical solutions:

[0007] A fireproof window, comprising:

[0008] The window keel comprises two mutually parallel longitudinal keels and two mutually parallel transverse keels connected end to end;

[0009] Insulation layers, disposed on both sides of the window keel for fireproofing and heat insulation, comprising a first insulation layer and a second insulation layer, an insulation cavity being defined between the first insulation layer and the second insulation layer, and the second insulation layer comprising two groups of fireproof glass layers and a laminated glass layer disposed between the two groups of fireproof glass layers;

[0010] The smoke-proof strip is arranged on the side wall of the window keel and is used to fill the gap to prevent smoke from passing through.

[0011] Preferably, a decorative layer is provided on the side wall of the window keel close to the isolation cavity, and the decorative layer is made of stainless steel.

[0012] Preferably, a raised portion is provided on the transverse keel, and the raised portion is used for plugging with the external wall panel.

[0013] Preferably, fireproof structural adhesive is filled between the window keel and the insulation layer.

[0014] Preferably, reinforcing ribs are provided inside the window keel.

[0015] Preferably, the window keel is made of high-temperature resistant metal material.

[0016] The beneficial effects of the utility model are as follows: through the cooperation of the insulating layer and the insulating cavity, heat transfer can be delayed, the spread of fire can be prevented, and the dual properties of fire prevention and heat insulation can be combined, thereby improving the use effect. In addition, under the action of the smoke-proof strips on both sides of the window keel, the smoke-proof strips expand when encountering fire and fill the gap between the window keel and the wall panel installation, thereby preventing smoke from spreading outward through the gap.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0024] Reference Figures 1-4 As shown, a fireproof window comprises a window keel 1 formed by connecting two mutually parallel longitudinal keels 11 and two mutually parallel transverse keels 12 end to end. The length of the window keel 1 can be customized according to the area of the fireproof window. An insulating layer is provided on both sides of the window keel 1 for heat insulation and fire prevention in the event of a fire. The insulating layer comprises a first insulating layer 2 and a second insulating layer 3. An insulating cavity 4 is provided between the first insulating layer 2, the second insulating layer 3 and the window keel 1. The insulating cavity 4 reduces the spread of heat radiation, prevents high temperature from invading adjacent spaces, and avoids rapid temperature increases in adjacent areas. The second insulating layer 3 comprises two groups of fireproof glass layers 31 and a laminated glass layer 32 provided between the two groups of fireproof glass layers 31. The laminated glass layer 32 can be a laminated glass with a thickness of 20 mm. It can be composed of two or more layers of glass with one or more layers of transparent organic polymer interlayer film sandwiched between them. Since the glue layer in the middle of the laminated glass usually has a low thermal conductivity, it is difficult for heat to be quickly transferred through the glue layer, thereby playing a role in heat insulation. In addition, the interlayer restricts the air convection between the two glass layers, making it difficult for heat to be quickly transferred through convection, thereby increasing the overall fireproof and heat-insulating capabilities. The first insulating layer 2 can also be made of fireproof glass, which can separate different areas when a fire occurs and prevent the spread of fire. While preventing fire, it cooperates with the fireproof glass layer 31 in the second insulating layer 3 and can provide a relatively clear field of view, making it easier for people to observe the fire scene and facilitate escape and rescue operations. Fireproof and heat-insulating are achieved through the multi-layer structure in the first insulating layer 2 and the second insulating layer 3, further improving the use effect.

[0025] In addition, a smoke-proof strip 5 is provided on the side wall of the window keel 1. The smoke-proof strip 5 is used to expand in the event of a fire to prevent smoke from spreading outward through the gap. The smoke-proof strip 5 can be made of special fire-proof materials, such as expanded graphite, ceramic fiber, silicone, etc. When a fire occurs, these materials will undergo physical or chemical changes at high temperatures and expand rapidly in volume, thereby sealing the gap between the window keel 1 and the wall panel to prevent the penetration of smoke and heat. For example, expanded graphite will expand dozens or even hundreds of times when heated, forming a sealed barrier to effectively block smoke and flames, thereby reducing the entry of smoke into the clean room.

[0026] Further, refer to Figure 2 As shown, a decorative layer 6 is provided on the side wall of the window keel 1 close to the insulating cavity 4, which can be used to decorate the window keel 1. When viewing the inside and outside of the fireproof window through the insulating layer, the decorative layer 6 covering the window keel 1 makes it more beautiful. The decorative layer 6 is made of stainless steel, which is not easy to rust and has a longer service life.

[0027] Further, such as Figure 4 As shown, in order to facilitate the installation of the fireproof window, a raised portion 7 is provided on the transverse keel 12, and the raised portion 7 is used to be plugged into the external wall panel. During installation, the raised portion 7 on the transverse keel 12 is inserted into the internal groove of the wall panel for plug-in connection, which is convenient for installation and highly operable.

[0028] Further, such as Figure 4 As shown, a fireproof structural adhesive 8 is filled between the window keel 1 and the insulating layer. The fireproof structural adhesive 8 is usually composed of organic or inorganic materials, including resin, filler, additives, etc. The fireproof structural adhesive 8 can form a fire barrier when a fire occurs, preventing flames and smoke from spreading through the gap between the window keel 1 and the insulating layer, thereby improving the fireproof performance of the entire window system. In addition, the fireproof structural adhesive 8 has good bonding properties, which can enhance the connection strength between the window keel 1 and the insulating layer and improve the overall structural stability of the window.

[0029] Furthermore, the interior of the window keel 1 is provided with reinforcing ribs 9, which can increase the rigidity and bending resistance of the window keel 1, making it less likely to deform or break when bearing loads, thereby further improving the service life of the window keel 1.

[0030] Among them, the material of the window keel 1 can be high-temperature resistant metal material, such as galvanized sheet, which is formed by bending. Compared with conventional aluminum profiles, it has better heat resistance and is not easy to deform when a fire occurs.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
