Technical Field
[0001] The utility model relates to the technical field of fire-resistant windows, and specifically to a fire-resistant window structure. Background Art
[0002] At present, the casement window is one of the most common window types on the market. As modern buildings are getting taller and taller, the fire protection requirements for windows are gradually increasing. Since casement windows have fast heat conduction, in order to prevent the glass window from cracking due to heat during a fire, a fireproof strip needs to be installed inside the window sash. After the fireproof strip expands due to heat, it can play a heat insulation role for the glass window and protect the glass window.
[0003] For example, the Chinese utility model patent with the patent application number "CN202221210523.5" provides a non-broken bridge inward-opening fire-resistant window, and the fireproof strip is arranged between the reinforcement plate in the installation groove and the glass window. When a fire occurs, the fireproof strip on the reinforcement plate expands due to heat and can fill the space between the glass window and the bottom of the installation groove, playing a heat insulation role for the glass window.
[0004] However, this patent has deficiencies. In order to fix the fireproof strip, reinforcement bars and screws are arranged on the reinforcement plate, and both the reinforcement bars and the screws penetrate through the fireproof strip. This will cause that when the top of the fireproof strip expands due to heat, it will be blocked by the reinforcement bars and the tops of the screws, and the top surface of the fireproof strip cannot correctly fit the bottom of the glass window, resulting in a decline in the heat insulation performance of the fireproof strip.

Detailed implementation manners
[0028] To make the purpose, technical solution and advantages of the present technical solution clearer and more understandable, the present technical solution will be further described in detail below in conjunction with specific implementation manners. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present technical solution.
[0029] Please refer to Figures 1 - 10, the present utility model provides a technical solution: a refractory window structure, including a window sash 1, a glass window 2, a reinforcement plate 3 and a fireproof strip 4. The glass window 2 is fixed to the top of the window sash 1 by sealant. The bottom of the glass window 2 extends into the first assembly cavity 11. The reinforcement plate 3 is in an L-shaped structure and is installed at the bottom inside the first assembly cavity 11. The fireproof strip 4 is arranged between the reinforcement plate 3 and the glass window 2. Please refer to Figures 2 - 4 , a first limiting member 12 is fixedly arranged at the bottom of the cavity of the first assembly cavity 11, and a second limiting member 31 is fixedly arranged on the side wall of the reinforcement plate 3. Through the first limiting member 12 and the second limiting member 31, the bottom of the fireproof strip 4 can be fixed on the reinforcement plate 3. Therefore, when the fireproof strip 4 expands due to heat, it will not move and will not break away from the reinforcement plate 3. The first end of the fireproof strip 4 is detachably connected to the first limiting member 12, and the second end of the fireproof strip 4 is detachably connected to the second limiting member 31. Therefore, the fireproof strip 4 can be conveniently installed, disassembled or replaced. The top surface of the fireproof strip 4 is a complete plane. Therefore, when the top of the fireproof strip 4 expands due to heat, it will not be hindered and can correctly fit the bottom of the glass window 2, ensuring that the fireproof strip 4 has good heat insulation performance.
[0030] Please refer to Figures 2 - 3 , the first limiting member 12 includes a first support plate 121, a first limiting plate 122 and a second limiting plate 123. Both the first limiting plate 122 and the second limiting plate 123 are in a C-shaped structure. Therefore, the first limiting plate 122 can hook the top of the left side of the fireproof strip 4, and the second limiting plate 123 can hook the bottom of the left side of the fireproof strip 4, preventing the left side of the fireproof strip 4 from moving when heated and expanding. Please refer to Figures 2 - 4 , the second limiting member 31 includes a second support plate 311 and a third limiting plate 312. The third limiting plate 312 is in a C-shaped structure. Therefore, the third limiting plate 312 can hook the top and bottom of the right side of the fireproof strip 4, preventing the right side of the fireproof strip 4 from moving when heated and expanding.
[0031] Please refer to Figure 3 and Figure 5 , a first assembly groove 41 is provided at the first end of the fireproof strip 4. Please refer to Figures 4 - 5 , a second assembly groove 42 is provided at the second end of the fireproof strip 4. Just align the first assembly groove 41 and the second assembly groove 42 with the first limiting member 12 and the second limiting member 31 respectively, and then push the fireproof strip 4 to move, then the operation of installing the fireproof strip 4 can be completed.

The guiding component 5 includes a baffle 51, the top surface of the baffle 51 abuts against the bottom surface of the glass window 2, and the end of the fireproof strip 4 abuts against the side wall of the baffle 51. When the fireproof strip 4 expands due to heat, the baffles 51 on both sides can block the fireproof strip 4 and guide the fireproof strip 4 to expand upward, and finally correctly fit against the bottom surface of the glass window 2.
[0033] Please refer to Figure 1 and Figure 6 , a third assembly groove 511 is provided at the first end of the baffle 51, and a fourth assembly groove 512 is provided at the second end of the baffle 51. Just align the third assembly groove 511 and the fourth assembly groove 512 with the first limiting member 12 and the second limiting member 31 respectively, and then push the baffle 51 to move, and the operation of installing the baffle 51 can be completed. Similarly, by pulling the baffle 51 outwards, the baffle 51 can be disassembled, and the operation of installing, disassembling or replacing the fireproof strip 4 can be completed.
[0034] Please refer to Figures 1 - 2 , a second assembly cavity 13 is further provided inside the window sash 1. A reinforcement component 6 is provided in the second assembly cavity 13. The reinforcement component 6 includes a reinforcement frame 61, two first buffer members 62 and four second buffer members 63.

The four second buffer members 63 are respectively arranged at the four corners of the reinforcement frame 61. When the bottom of the window sash 1 is hit, the first buffer member 62 and the second buffer member 63 can absorb the impact force. Even if the bottom of the window sash 1 is damaged, the reinforcement frame 61 can withstand the impact, improving the strength of the present utility model. The inside of the reinforcement frame 61 is filled with heat insulation cotton 7, so the reinforcement component 6 can further play a role in heat insulation.
[0035] Please refer to Figures 1 - 3 and Figures 5 - 6 , the guiding component 5 further includes a plug board 52. A slot 32 is provided on the reinforcement plate 3. The shape of the slot 32 matches the shape of the plug board 52, and the plug board 52 can slide along the slot 32. The first buffer member 62 located above can be connected to the plug board 52. At this time, the reinforcement plate 3, the guiding component 5 and the reinforcement frame 61 can all be fixed to the first buffer member 62, and there can be no relative displacement between them, ensuring the stability of the present utility model during use.
[0036] Please refer to Figures 1 - 3 and Figures 6 - 9, the first buffer member 62 includes a first connecting plate 621, two first elastic bending plates 622, two second connecting plates 623, and screws 624. A first threaded hole 521 is provided in the middle of the insertion plate 52, a second threaded hole 33 is provided in the bottom surface of the reinforcing plate 3, a third threaded hole 14 is provided in the bottom of the first assembly cavity 11, and a fourth threaded hole 6211 is provided in the middle of the first connecting plate 621. If screws 624 are screwed into the first threaded hole 521, the second threaded hole 33, the third threaded hole 14, and the fourth threaded hole 6211, the reinforcing plate 3, the guiding assembly 5, and the reinforcing frame 61 can be fixed together with the first buffer member 62. In the present utility model, the first buffer member 62 located below and the first buffer member 62 located above are mirror-symmetric in structure, and the first buffer member 62 located below is fixed to the bottom of the window sash 1 by screws 624. If the screws 624 are unscrewed, the reinforcing plate 3, the guiding assembly 5, and the reinforcing frame 61 can be separated from the first buffer member 62 located above and can all be disassembled from the window sash 1. Please refer to Figures 1 - 2 , Figure 8 and Figure 10 , the second buffer member 63 includes two third connecting plates 631 and a second elastic bending plate 632.
[0037] In the present utility model, the second connecting plate 623 is fixedly connected to the reinforcing frame 61, the two third connecting plates 631 are respectively fixedly connected to the reinforcing frame 61 and the side wall of the second assembly cavity 13, and the two ends of the second elastic bending plate 632 are respectively fixedly connected to the two third connecting plates 631. When the bottom of the window sash 1 is impacted, the impacted part of the window sash 1 can transmit the force to the reinforcing frame 61 through the second buffer member 63, and then transmit it to the middle of the window sash 1 through the first buffer member 62. During this process, both the first elastic bending plate 622 and the second elastic bending plate 632 can generate elastic deformation to absorb the impact force, ensuring that the middle part of the window sash 1 is not damaged, and further ensuring that the fireproof strip 4 is not damaged. In addition, when the impact force is large, the first elastic bending plate 622 and the second elastic bending plate 632 can also break. When the first elastic bending plate 622 and the second elastic bending plate 632 break, they also absorb the impact force to further protect the middle part of the window sash 1 from being damaged.
