[0002] Glass flooring refers to a special type of flooring that uses high-strength, high-safety glass as the main load-bearing surface for floor decoration or structure. It has good light transmission and decorative effect, while also having load-bearing capacity and safety. It is often used in viewing platforms, exhibition venues, or modern buildings.
[0003] Current glass floor designs focus more on their mechanical structural performance, such as load-bearing capacity, impact resistance, and durability, to ensure their safety and stability in daily use. However, they lack consideration for the fire resistance of the floor. For example, the "glass floor" disclosed in patent document "CN101718143A" focuses more on the light transmission and anti-slip properties of the glass floor, while neglecting the fire resistance of the glass floor.
[0004] In this patent, the glass floor may lose its load-bearing capacity due to thermal expansion, softening or cracking in high temperature or fire environments, and cannot effectively prevent the spread of flames and high temperatures, thus posing a potential threat to personnel safety and building fire resistance.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] Please refer to Figure 1-3 ;
[0024] Current glass floor designs primarily focus on light transmission, slip resistance, and mechanical properties, but pay less attention to fire resistance. This can lead to the glass softening and cracking under high temperatures or in a fire, causing it to lose its load-bearing capacity. Therefore, there is a need for a heat-insulating and fire-resistant glass floor with safe performance.
[0025] This application discloses a heat-insulating and fireproof glass floor, including a steel frame 1, a fireproof board 2, and a fireproof cotton pad 3. The steel frame 1 is used to fix and connect to the exterior wall. The fireproof board 2 is installed on the side and bottom of the steel frame 1. The fireproof cotton pad 3 is installed on the upper surface of the steel frame 1 and the fireproof board 2. A plurality of fireproof glass bodies 4 are provided on the fireproof cotton pad 3. The fireproof glass bodies 4 are bonded together by glass glue 5.
[0026] Specifically, the fire-resistant insulated glass floor of this application achieves a combination of load-bearing, heat insulation, and fire resistance through a multi-layered structural design of a steel frame 1, fireproof board 2, fireproof cotton pad 3, and fireproof glass body 4. In this embodiment, the steel frame 1 adopts a frame structure, made of high-strength carbon steel or stainless steel, with a surface treated for corrosion resistance, and is securely connected to the exterior wall by expansion bolts or chemical anchors. In some other embodiments, the steel frame 1 adopts a grid structure. In this embodiment, the fireproof board 2 includes calcium silicate board and fiber-reinforced cement board, fixed to the sides and bottom of the steel frame 1 to form a robust fire barrier. The fireproof cotton pad 3 is made of high-density fireproof rock wool or ceramic fiber cotton, laid on top of the steel frame 1 and fireproof board 2, providing heat insulation and flexible support for the fireproof glass body 4. The fireproof glass body 4 has transparency and mechanical properties. Regarding mechanical strength, in this embodiment, the number of fireproof glass bodies 4 is not limited. The fireproof glass bodies 4 are bonded together with glass glue 5. More specifically, high-temperature resistant silicone glass glue 5 can be used for bonding and sealing to prevent flames and heat from spreading through gaps. During assembly, the operator first fixes the steel frame 1 to the exterior wall, then installs the fireproof boards 2 on the sides and bottom of the steel frame 1 in sequence, then lays fireproof cotton pads 3 to ensure even coverage, and finally installs the fireproof glass bodies 4 one by one and seals the joints with glass glue 5 to form a high-strength, high-temperature resistant, and transparent fireproof glass floor structure, meeting the requirements of building safety and aesthetics.
[0027] In the event of a fire, the steel frame 1, serving as the main load-bearing structure of the entire floor, maintains structural stability under high temperatures. The fireproof board 2, fixed to the sides and bottom of the steel frame 1, directly blocks the intrusion of flames and high-temperature gases. The fireproof cotton pad 3, located between the steel frame 1 and the fireproof glass body 4, effectively blocks heat transfer to the upper layers during a fire, while providing cushioning support for the fireproof glass body 4 to prevent it from cracking due to thermal expansion or impact. The fireproof glass body 4 rapidly absorbs heat and expands, forming an opaque heat insulation barrier that blocks heat radiation and flame spread, while maintaining mechanical strength to ensure the floor's stability. The load-bearing capacity is superior. Compared to ordinary non-fireproof glass floors, this insulated fireproof glass floor has significant technical advantages in terms of safety. Ordinary glass floors usually crack rapidly due to thermal expansion in high-temperature environments, leading to falling fragments and structural failure. However, this insulated fireproof glass floor can maintain its integrity at high temperatures, effectively blocking the spread of flames, heat radiation, and smoke. In addition, the steel structure of ordinary glass floors is prone to losing its load-bearing capacity due to high temperatures in a fire. However, the steel frame 1 of this insulated fireproof glass floor is protected by fireproof boards 2 and fireproof cotton pads 3, which can significantly delay the time of structural failure and maintain overall stability.
[0028] In this embodiment, the fireproof glass body 4 includes an outer glass layer 41 and an inner glass layer 42. A PVB film layer 43, such as a polyvinyl butyral film layer, is disposed inside the outer glass layer 41. A PVB film layer 44 is disposed inside the inner glass layer 42. A space for installing a fireproof layer 45 is provided between the outer glass layer 41 and the inner glass layer 42. Further, the fireproof layer 45 includes a transparent high-temperature resistant film 451, a transparent fireproof heat-absorbing gel layer 452, and a fireproof expansion coating 453. The outer glass layer 41 is bonded to the transparent high-temperature resistant film 451, the transparent high-temperature resistant film 451 is bonded to the transparent fireproof heat-absorbing gel layer 452, and the transparent fireproof heat-absorbing gel layer 452 is bonded to the fireproof expansion coating 453.
[0029] Specifically, when a fire occurs, even if the outer glass 41 breaks due to heat or external force, the PVB film layer 43 can effectively adhere to the glass fragments, preventing them from flying and protecting personnel safety. The outer glass 41 is bonded to the transparent high-temperature resistant film 451, which maintains its integrity under high-temperature conditions during a fire, acting as the first line of defense to block some heat radiation and flame intrusion. The transparent fire-resistant heat-absorbing gel layer 452 can rapidly absorb heat and expand during a fire, forming an opaque heat-insulating barrier that significantly reduces the transfer of heat and flames to the inner glass 42. The fire-resistant intumescent coating 453 undergoes a chemical reaction at high temperatures, further expanding to form a dense protective layer that blocks the invasion of flames and high-temperature gases. In this embodiment, the fire-resistant glass body 4 can effectively block flames, heat radiation, and smoke during a fire, buying more time for personnel evacuation and fire rescue, while also preventing secondary injuries to personnel from broken glass, thus improving the safety of the building.
[0030] In some other embodiments, the thickness ratio of the transparent high-temperature resistant film 451, the transparent fire-retardant heat-absorbing gel layer 452, and the fire-retardant intumescent coating 453 is 1:5:1; further, the transparent high-temperature resistant film 451 comprises a polyimide film with a thickness of 1.5mm-2.5mm; the transparent fire-retardant heat-absorbing gel layer 452 comprises a silica-based fire-retardant gel with a thickness of 7.5mm-12.5mm; and the fire-retardant intumescent coating 453 comprises an inorganic silicate coating with a thickness of 1.5mm-2.5mm.
[0031] Specifically, in this embodiment, the polyimide film has a thickness of 2.0 mm, the silica-based fire-retardant gel has a thickness of 10 mm, and the inorganic silicate coating has a thickness of 2.0 mm. The polyimide film is bonded to the silica-based fire-retardant gel, and the silica-based fire-retardant gel is bonded to the inorganic silicate coating to form a composite fire-retardant layer 45. When a fire occurs, the 2.0 mm thick polyimide film, as the surface material, has excellent high-temperature resistance and flame-retardant properties. In the early stages of a fire, it can quickly form the first protective barrier, preventing flames from directly contacting the internal materials and effectively reducing the penetration of heat radiation; the 10 mm thick silica-based fire-retardant gel is bonded to the inorganic silicate coating. As the core insulation layer, the silica-based fire-retardant gel can absorb a large amount of heat energy in high-temperature environments, significantly reducing the rate of heat transfer. At the same time, its gel-like properties may expand and fill when heated, further blocking the penetration paths of flames and smoke, ensuring that the internal temperature remains within a safe range. The 2.0mm thick inorganic silicate coating will expand or carbonize under high temperatures in a fire, forming a dense protective barrier that can block the intrusion of flames and high-temperature gases. It also provides additional protection for the silica-based fire-retardant gel, preventing it from failing due to direct heat, thereby significantly improving the fire resistance and overall safety of this fire-resistant insulated floor.
[0032] In this embodiment, the thickness of the fireproof glass body 4 is in the range of 50mm-79mm, so as to be better applied in this heat-insulating and fireproof floor. Preferably, the thickness of the fireproof glass body 4 is in the range of 63mm, and the corresponding size of the fireproof glass body 4 is 1284mm x 1914mm.
