Description

Technical Field

[0001] This application relates to the field of glass, and more particularly to a heat-insulating and fire-resistant glass. Background Technology

[0002] Fire-resistant glass primarily functions to control the spread of fire or isolate smoke during fires. It is a type of fire-resistant material used as a preventative measure, and its fire-resistant effect is evaluated based on its fire resistance performance. It is a special type of glass that undergoes special processing and treatment to maintain its integrity and heat insulation properties during specified fire resistance tests. The base glass for fire-resistant glass can be float glass, tempered glass, or, for composite fire-resistant glass, monolayer fire-resistant glass.

[0003] Fire-resistant insulated glass typically consists of two layers of glass. The edges of the glass are sealed with a special flame-retardant strip, and a fire-retardant adhesive is poured into the middle. After curing, it becomes a transparent gel and bonds to the glass. When exposed to high temperatures, the transparent, gel-like fire-retardant adhesive in the middle of the glass quickly hardens, forming an opaque fire-resistant and heat-insulating board, thereby preventing the spread of flames and preventing high temperatures from being conducted to the other side of the flames.

[0004] However, this type of heat-insulating and fire-resistant glass has poor weather resistance and is prone to problems such as glue leakage, bubbles, and yellowing after being left for a long time. Summary of the Invention

[0005] The purpose of this application is to provide a heat-insulating and fire-resistant glass to improve its weather resistance and extend its service life.

[0006] The heat-insulating and fire-resistant glass provided in this application adopts the following technical solution: A heat-insulating and fire-resistant glass includes two tempered glass panes arranged in parallel. A sealing strip is provided at the edge of the two tempered glass panes to connect the two panes. The two tempered glass panes and the sealing strip form a receiving cavity. The receiving cavity is further provided with a plurality of blades arranged in parallel. The blades are provided with cavities that communicate with the receiving cavity. The cavities are filled with fire-resistant expanding material.

[0007] By adopting the above technical solution, when the heat-insulating and fire-resistant glass is subjected to high temperatures, the fire-resistant expansion material inside the blades expands due to heat and fills the cavity, thereby forming a heat-insulating and fire-resistant layer. This prevents the spread of flames and high temperatures, maintaining good fire resistance. The fire-resistant expansion material is normally stored inside the blades and does not come into contact with the tempered glass on both sides. The cavity will not experience problems such as glue leakage, bubbles, or yellowing due to the aging of the fire-resistant adhesive. As a result, the weather resistance of the heat-insulating and fire-resistant glass is improved, thereby extending its service life.

[0008] Optionally, the fire-resistant expansion material is sodium silicate.

[0009] By adopting the above technical solution, sodium silicate expands tenfold when heated, which can quickly fill the cavity.

[0010] Optionally, a retractable assembly connecting all blades is provided on one side of the receiving cavity. The retractable assembly includes a movable block disposed at the end of the blade. A groove is provided on the side of the sealing strip facing the receiving cavity. The movable block is slidably connected in the groove. A drive screw rotatably connected to the sealing strip is provided in the groove. A slider connected to the movable block is also slidably connected in the groove. The drive screw passes through the movable block and the slider, and the drive screw is threadedly connected to the slider. A drive motor for driving the drive screw to rotate is provided on the side of the sealing strip away from the receiving cavity. A belt connecting the two drive screws is provided between the two drive screws.

[0011] By adopting the above technical solution, the retractable assembly drives the slider to move via a drive motor. The slider drives the moving block to move, and the moving block simultaneously drives the blade to move, so that the blade can move within the receiving groove. When the heat-insulating and fireproof glass is heated, the fire-resistant expansion material inside the blade expands and fills the receiving groove. The movement of the blade can quickly fill the receiving groove with the fire-resistant expansion material, thereby quickly achieving the fireproof effect.

[0012] Optionally, a connecting block is provided between adjacent moving blocks. A connecting groove is provided on the outer side wall of the connecting block. A stop block is provided in the middle part of the connecting groove. Positioning blocks are provided on both sides of the stop block and are slidably connected in the connecting groove. The positioning blocks are fixedly connected to the corresponding moving blocks. The moving block farthest from the drive motor is fixedly connected to the slider.

[0013] By adopting the above technical solution, when the drive screw drives the slider to move away from the drive motor, the slider drives one of the moving blocks to move. The moving block moves relative to the connecting block, so that the positioning block slides away from the stop block. When all the positioning blocks abut against the side wall of the connecting groove away from the stop block, all the moving blocks are separated by a certain distance. Thus, the blades are evenly distributed in the receiving cavity, which facilitates the filling of the receiving cavity with fireproof expansion material.

[0014] Optionally, the sealing strip is provided with an angle adjustment component, which is connected to the blade.

[0015] By adopting the above technical solution, the angle adjustment component can adjust the blade angle. When the blade is evenly spread inside the receiving cavity, the angle adjustment component adjusts the blade rotation, thereby adjusting the light transmittance of the heat-insulating and fireproof glass. When it is necessary to store the blade, all blades are adjusted to be perpendicular to the tempered glass. Then the retraction component drives all moving blocks to move towards the drive motor, thereby reducing the distance between the blades and storing the blade.

[0016] Optionally, the blade is rotatably connected to the moving block, an adjustment cavity is provided in the sealing strip, the angle adjustment assembly includes a rack disposed in the adjustment cavity, a gear is provided on the blade that meshes with the rack, a torsion spring is provided between the blade and the moving block, an electric telescopic rod is hinged to the side of the rack away from the gear, the end of the electric telescopic rod away from the rack is inclined and hinged to the sealing strip.

[0017] By adopting the above technical solution, when the gear and rack are not meshed, all blades are perpendicular to the tempered glass, which reduces the distance between the blades. When the blade angle needs to be adjusted, the electric telescopic rod extends, and the rack moves to the side where the gear is located. When the rack meshes with the gear, the electric telescopic rod continues to extend, and the rack slides in a direction parallel to the slide groove, thereby driving the gear to rotate, thus adjusting the blade angle.

[0018] Optionally, the two tempered glass pieces are provided with caps at the ends near the drive motor. The two tempered glass pieces are inserted into the caps and abut against the inner wall of the caps. The caps are provided with snap-fit ​​blocks inside, and the sealing strip is provided with snap-fit ​​grooves for accommodating the snap-fit ​​blocks on the side away from the receiving cavity.

[0019] By adopting the above technical solution, the cap shell is snapped into the tempered glass through the snap-fit ​​block and snap-fit ​​groove, thereby protecting the drive motor. When the blade is stored, the cap shell can cover the blade, thereby improving the overall aesthetics.

[0020] Optionally, the cap shell is equipped with a temperature sensor and a controller, and the temperature sensor, the drive motor and the electric telescopic rod are all electrically connected to the controller.

[0021] By adopting the above technical solution, when the temperature sensor detects that the indoor temperature exceeds 200°C, the controller controls the drive motor to start, thereby spreading the blades evenly into the receiving groove. Finally, the electric telescopic rod adjusts the angle of the blades so that the blades are parallel to the tempered glass. When the fire-resistant expansion material is heated, the fire-resistant expansion material can quickly contact the tempered glass and fill the receiving cavity.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The fire-resistant expansion material is normally stored inside the blades and does not come into contact with the tempered glass on both sides. The cavity will not produce problems such as glue leakage, bubbles and yellowing due to the aging of fire-resistant adhesive. As a result, the weather resistance of the heat-insulating fireproof glass is improved, thereby extending the service life of the heat-insulating fireproof glass. 2. When the heat-insulating and fire-resistant glass requires good light transmission, the retractable assembly will retract the blades. When the heat-insulating and fire-resistant glass needs to block light, the retractable assembly, together with the angle-adjusting assembly, will drive the blades to block the light, while facilitating the rapid filling of the cavity with fire-resistant expansion material.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0025] Example: A heat-insulating and fire-resistant glass, referring to Figure 1 and Figure 2 The device includes two parallel and spaced tempered glass panes 1, with a sealing strip 2 between them. The sealing strip 2 is distributed along the edge of the tempered glass panes 1 and is fixedly connected to the two tempered glass panes 1. The two tempered glass panes 1 and the sealing strip 2 together form a receiving cavity 3. A fixing frame 8 is fixed on the outside of the sealing strip 2, distributed along the sealing strip 2. The fixing frame 8 is U-shaped. The sealing strip 2 is also provided with a cap 4 that abuts against the fixing frame 8. The two ends of the cap 4 abut against the ends of the fixing frame 8. The two ends of the cap 4 are fixedly connected to the side wall of the sealing strip 2 near the two ends of the cap 4. The sealing strip 2 has a snap-fit ​​groove 21, and the snap-fit ​​block 41 is inserted into the snap-fit ​​groove 21. The cap 4 can cover part of the tempered glass panes 1.

[0026] Inside the cavity 3, there are multiple blades 5 arranged sequentially from top to bottom. Each blade 5 has a cavity inside. On both sides of the blade 5, there are multiple through holes 51 that connect the cavity and the cavity 3. The cavity is filled with fire-resistant expanding material, which is sodium silicate. Sodium silicate expands tenfold when heated, and can quickly fill the cavity 3.

[0027] The fire-resistant expanding material is normally stored inside the blade 5 and does not come into contact with the tempered glass 1 on both sides. When the heat-insulating and fire-resistant glass is subjected to high temperature, the fire-resistant expanding material inside the blade 5 expands due to heat and fills the cavity 3, thereby forming a heat-insulating and fire-resistant layer, which in turn prevents the spread of flames and high temperature.

[0028] The receiving cavity 3 is also equipped with a retractable assembly 6 for driving the blade 5 to move. The retractable assembly 6 includes a moving block 61, with a moving block 61 at each end of the blade 5. A sliding groove 22 is provided on the side of the sealing strip 2 facing the receiving cavity 3. The moving block 61 is inserted into the sliding groove 22 and slides along the sliding groove 22. A connecting block 62 is provided between two adjacent moving blocks 61. A connecting groove is provided on the outer wall of the connecting block 62. A stop block 63 located in the middle of the connecting groove is fixedly connected to the connecting block 62. Positioning blocks 64 are provided on both sides of the stop block 63 and are slidably connected in the connecting groove. The positioning blocks 64 are fixedly connected to the adjacent moving block 61.

[0029] A drive screw 65 parallel to the slide groove 22 is also provided inside the slide groove 22. The drive screw 65 passes through all the moving blocks 61 and connecting blocks 62 in the same slide groove 22. The drive screw 65 is rotatably connected to the sealing strip 2. A drive motor 66 mounted on the sealing strip 2 is provided inside the cap 4. The output shaft of the drive motor 66 is fixed coaxially with one of the drive screws 65. A belt is provided between the two drive screws 65 to connect them. A slider 67 is threadedly connected to the drive screw 65. The slider 67 is slidably connected in the slide groove 22, and the slider 67 is fixedly connected to the moving block 61 farthest from the drive motor 66.

[0030] The retractable assembly 6 drives the slider 67 to move via the drive motor 66. When the slider 67 moves away from the drive motor 66, it drives one of the moving blocks 61 to move. The moving block 61 moves relative to the connecting block 62, causing the positioning block 64 to slide away from the stop block 63. When all the positioning blocks 64 abut against the side wall of the connecting groove away from the stop block 63, all the moving blocks 61 are separated by a certain distance, so that the blades 5 are evenly distributed in the receiving cavity 3, which facilitates the filling of the receiving cavity 3 with fire-resistant expansion material. Conversely, when the slider 67 moves towards the drive motor 66, the connecting block 62 and the moving block 61 move closer to each other. The moving block 61 is set in an I-shape so that the connecting block 62 can be inserted into the moving block 61 until the positioning block 64 abuts against the stop block 63, which allows the blades 5 to move closer to each other, making it convenient for the blades 5 to be stored.

[0031] Reference Figure 2 and Figure 3The blade 5 is rotatably connected to the moving block 61. The sealing strip 2 also contains an angle adjustment component 7 for adjusting the angle of the blade 5. The angle adjustment component 7 includes a gear 71 fixed to one end of the blade 5 on a coaxial axis. An adjustment cavity 23 is provided on the side of the sealing strip 2 closest to the blade 5. Inside the adjustment cavity 23 is a rack 72 that can mesh with the gear 71. The internal volume of the adjustment cavity 23 is larger than that of the rack 72. Multiple parallel electric telescopic rods 73 are hinged to the side of the rack 72 away from the gear 71. The ends of the electric telescopic rods 73 away from the rack 72 are inclined and hinged to the sealing strip 2. A torsion spring 74 is fixedly connected to the other end of the blade 5, and the torsion spring 74 is also fixedly connected to the moving block 61.

[0032] When the electric telescopic rod 73 extends, the rack 72 meshes with the gear 71. The electric telescopic rod 73 continues to extend and rotates under the action of resistance, causing the rack 72 to slide along the direction of the slide groove 22, thereby driving the gear 71 to rotate. The blade 5 rotates accordingly. When the electric telescopic rod 73 retracts, the rack 72 separates from the gear 71, and the torsion spring 74 drives the blade 5 back to its original position.

[0033] When the blades 5 are evenly spread inside the receiving cavity 3, the angle adjustment component 7 can adjust the light transmittance of the heat-insulating and fireproof glass. When it is necessary to store the blades 5, the angle adjustment component 7 adjusts all the blades 5 to be perpendicular to the tempered glass 1. Then the retraction component 6 drives all the moving blocks 61 to move towards the drive motor 66, thereby reducing the distance between the blades 5, thereby storing the blades 5 and covering them with the cap 4.

[0034] The temperature sensor and controller are also installed inside the cap shell 4. The temperature sensor, drive motor 66 and electric telescopic rod 73 are all electrically connected to the controller.

[0035] When the temperature sensor detects that the indoor temperature exceeds 200°C, the controller controls the drive motor 66 to start, thereby spreading the blade 5 evenly into the receiving groove. Finally, the electric telescopic rod 73 adjusts the angle of the blade 5 so that the blade 5 is parallel to the tempered glass 1. When the fire-resistant expansion material is heated, the fire-resistant expansion material can quickly contact the tempered glass 1 and fill the receiving cavity 3.

[0036] The implementation principle of this application embodiment is as follows: When no fire occurs, the retractable assembly 6 drives the blade 5 to position inside the heat-insulating and fireproof glass, thereby adjusting the light transmittance of the heat-insulating and fireproof glass. When a fire occurs, the temperature sensor transmits the indoor temperature to the controller. The controller controls the drive motor 66 to adjust the position of the blade 5 so that the blade 5 is evenly spread into the receiving groove. Subsequently, the controller controls the electric telescopic rod 73 to adjust the angle of the blade 5 so that the blade 5 is parallel to the tempered glass 1. When the fire-resistant expansion material is heated, the fire-resistant expansion material can quickly contact the tempered glass 1 and fill the receiving cavity 3.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
