Abstract
Description
Technical Field
[0001] This application relates to the field of building curtain wall technology, and in particular to a fireproof structure based on building curtain walls. Background Technology
[0002] Building curtain walls typically refer to the non-load-bearing exterior wall cladding of a building, mainly composed of panels and supporting structures. Currently, glass curtain walls are commonly used in office buildings and other similar structures.
[0003] In related technologies, building curtain walls include horizontal beams, vertical beams, and glass. Grooves are provided in both the horizontal and vertical beams. The horizontal edges of the glass are fixed within the grooves in the horizontal beams, and the vertical edges are fixed within the grooves in the vertical beams, thus securing the glass between the horizontal and vertical beams. When a fire occurs in the building, the temperature rises rapidly, causing the curtain wall glass to crack and fall quickly. The fire can easily spread from the outside of the curtain wall to the upper glass, further cracking the upper glass, and eventually into the upper interior, resulting in a rapid spread of the fire. Summary of the Invention
[0004] To help improve the fire resistance of curtain wall glass, make it less prone to breakage, and slow down the spread of fire to a certain extent, this application provides a fire-resistant structure based on building curtain walls.
[0005] The fire-resistant structure based on building curtain walls provided in this application adopts the following technical solution:
[0006] A fire-resistant structure based on a building curtain wall includes horizontal beams, vertical beams, and curtain wall glass disposed between the horizontal beams and vertical beams. An installation groove is formed on the side of the horizontal beam closest to the lower curtain wall glass. A glass box is disposed within the installation groove, and the glass box stores fire-retardant coating. The fire resistance of the glass box is lower than that of the curtain wall glass. A baffle is disposed on the inner wall of the installation groove away from the curtain wall glass. The length direction of the baffle is parallel to the length direction of the horizontal beam. The baffle is located below the glass box and is used to guide the fire-retardant coating onto the curtain wall glass.
[0007] By adopting the above technical solution, when a building catches fire, the temperature rises rapidly. Because the fire resistance of the glass box is lower than that of the curtain wall glass, the glass box breaks before the curtain wall glass. The fire-retardant coating inside the glass box flows out and flows along the baffle towards the curtain wall glass. Then, the fire-retardant coating flows downward from the curtain wall glass and coats its surface. The fire-retardant coating has good fire-retardant properties, thereby improving the fire resistance of the curtain wall glass. This makes the curtain wall glass less likely to break during a fire, and to a certain extent, it prevents the fire from spreading upward and slows down the spread of the fire.
[0008] Preferably, the baffle rotates on the inner wall of the mounting groove on the side away from the curtain wall glass. The rotation axis of the baffle is parallel to the length direction of the crossbeam. The cross-section of the baffle is adapted to the cross-section of the mounting groove. The baffle rotates in a direction closer to or further away from the mounting groove. An adjustment mechanism for adjusting the baffle to close or open the mounting groove is provided inside the crossbeam. A limit block is provided on the crossbeam. The limit block is located below the rotation axis of the baffle. The side of the limit block closer to the glass box is used to abut against the side of the baffle away from the glass box.
[0009] By adopting the above technical solution, the baffle rotates towards the mounting groove, and the baffle is adjusted by the adjustment mechanism to close the mounting groove, thereby facilitating the protection of the fire-retardant coating inside the glass box. In the event of a fire, as the temperature rises, the glass box breaks before the curtain wall glass. The baffle is adjusted by the adjustment mechanism to open the mounting groove. Under the action of the fire-retardant coating and the weight of the baffle itself, the baffle rotates away from the mounting groove until it abuts against the limiting block. At this time, the side of the baffle closest to the curtain wall glass tilts downward to guide the fire-retardant coating, so that the fire-retardant coating can flow onto the curtain wall glass, providing a certain degree of protection for the curtain wall glass. This improves the fire resistance of the curtain wall glass to a certain extent, making it less likely for the curtain wall glass to break in a short time, and helps to slow down the spread of fire.
[0010] Preferably, the adjustment mechanism includes a rod slidably disposed on the inner wall of the mounting groove and an adjustment component disposed on the crossbeam. The rod slides toward or away from the baffle. The baffle has a slot on its side wall near the rod for insertion and engagement with the rod. The adjustment component is used to adjust the rod to slide toward or away from the slot. When the rod is inserted into the slot, the baffle closes the mounting groove.
[0011] By adopting the above technical solution, the baffle is rotated towards the mounting groove, aligning the slot and the rod on the baffle. The rod is then slid towards the baffle using the adjusting component, allowing it to engage with the slot, thus sealing the mounting groove and protecting the glass box. In the event of a fire, as the temperature rises, the rod is slid away from the baffle using the adjusting component, disengaging it from the slot. At this point, the baffle rotates away from the mounting groove under its own weight until it abuts against the limiting block, facilitating the flow of fire-retardant coating to the curtain wall glass. This improves the fire resistance of the curtain wall glass, making it less prone to cracking in a short time and slowing the spread of fire to some extent.
[0012] Preferably, the glass box is movably placed in the mounting groove, the limiting block slides on the crossbeam, the sliding direction of the limiting block is parallel to the length direction of the crossbeam, the limiting block slides toward or away from the baffle, the side of the limiting block away from the glass box is an arc surface, the side of the arc surface near the baffle is inclined upward, and a first spring is provided between the crossbeam and the limiting block to push the limiting block to slide toward the baffle.
[0013] By adopting the above technical solution, the baffle is rotated in the direction away from the mounting groove, which facilitates the placement of the glass box and provides convenience for the installation of the fireproof structure. When the baffle is rotated in the direction closer to the mounting groove, the baffle first slides relative to the arc surface of the limiting block, pushing the limiting block to slide in the direction away from the baffle, compressing the first spring, until the baffle rotates above the limiting block, and the first spring pushes the limiting block to slide in the direction closer to the baffle, which helps to limit the rotation angle of the baffle in the future.
[0014] Preferably, the adjustment assembly includes an adjustment rod slidably disposed in the mounting groove, a pull rope disposed on the adjustment rod, a pulling member disposed in the crossbeam, and a pushing member disposed in the crossbeam. The sliding direction of the adjustment rod is vertical, and the adjustment rod is located above the glass box. One end of the adjustment rod near the glass box is used to abut against the glass box. One end of the pull rope is disposed on the adjustment rod, and the other end slides through the crossbeam and is disposed on the insertion rod. The pull rope is used to pull the insertion rod to slide away from the baffle. The pulling member is used to pull the adjustment rod to slide towards the glass box. The pushing member is used to push the insertion rod to slide towards the baffle. When the adjustment rod slides towards the glass box, the pull rope pulls the insertion rod to slide away from the baffle. The pulling force of the pulling member is greater than the pushing force of the pushing member. The depth of the mounting groove is greater than the thickness of the glass box. The baffle is provided with a lifting member for pushing the glass box to slide towards the adjustment rod.
[0015] By adopting the above technical solution, the glass box is placed into the mounting slot, and then the baffle is rotated towards the mounting slot to align the slot with the insertion rod. Then, the lifting component pushes the glass box towards the adjusting rod, and the glass box gradually slides away from the adjusting rod. At this point, the tension of the pull rope on the insertion rod decreases. The pushing component then pushes the insertion rod towards the baffle, allowing the insertion rod to engage with the slot, thereby sealing the mounting slot and securing the glass box. When the glass box breaks, the resistance force of the glass box against the adjusting rod decreases. The small mechanism allows the adjusting rod to slide closer to the baffle by pulling the puller. At this time, the pull rope pulls the insert rod to slide away from the baffle, causing the insert rod to disengage from the slot. Then, under the action of the fire-retardant coating and the weight of the baffle itself, the baffle rotates away from the mounting slot to open the mounting slot until the baffle rotates to abut against the side of the limiting block near the glass box. At this time, the baffle is in an inclined state, and the fire-retardant coating flows along the baffle onto the curtain wall glass, which helps to improve the fire resistance of the curtain wall glass, making it less likely to break in a short time and slowing down the spread of fire to a certain extent.
[0016] Preferably, the pulling member includes a tension spring for pulling the adjusting rod to slide towards the glass box, one end of the tension spring being disposed on the adjusting rod and the other end being disposed inside the crossbeam.
[0017] By adopting the above technical solution, the pulling member pulls the adjusting rod to slide towards the glass box, which helps the pull rope pull the insertion rod to slide away from the baffle, so that the insertion rod is disengaged from the slot. This facilitates the rotation of the baffle away from the installation groove, helps to open the installation groove, and allows the fireproof coating to flow onto the curtain wall glass. As a result, the curtain wall glass is less likely to break in a short time, which slows down the spread of fire to a certain extent.
[0018] Preferably, the pushing member includes a second spring for pushing the insertion rod to slide in a direction close to the baffle, one end of the second spring being disposed on the insertion rod and the other end being disposed inside the crossbeam.
[0019] By adopting the above technical solution, the second spring pushes the insertion rod to move towards the baffle, so that the insertion rod and the slot can be inserted and matched, thereby facilitating the sealing of the baffle mounting groove and helping to protect the glass box.
[0020] Preferably, the lifting member includes a screw threaded through the baffle, the rotation axis of the screw being perpendicular to the plane of the baffle, and the side of the screw near the glass box being used to abut against the glass box.
[0021] By adopting the above technical solution, the screw is rotated and screwed in the direction closer to the glass box, so that the screw abuts against the glass box, so that the glass box can push the adjusting rod to move away from the baffle; at the same time, it is convenient to fix the glass box.
[0022] Preferably, a receiving groove is formed on the inner wall of the mounting groove, the receiving groove is located above the baffle, the distance from the inner wall of the receiving groove away from the baffle to the bottom wall of the mounting groove is greater than the thickness of the glass box, a receiving plate is hinged on the inner wall of the receiving groove near the baffle, the receiving plate can rotate into or out of the receiving groove, the receiving plate is used to support the glass box, a torsion spring is sleeved on the hinge shaft of the receiving plate, the torsion spring is used to drive the receiving plate to rotate in the direction away from the receiving groove until it abuts against the inner wall of the receiving groove near the baffle, one end of the torsion spring is set in the receiving groove, and the other end is set on the receiving plate.
[0023] By adopting the above technical solution, when the glass box is placed into the installation slot, the glass box moves upward along the installation slot, gradually pushing the receiving plate to rotate towards the receiving slot. The glass box continues to move upward, so that the receiving plate is completely rotated into the receiving slot. Then the glass box separates from the receiving plate. At this time, the torsion spring drives the receiving plate to rotate away from the receiving slot until it abuts against the inner wall of the receiving slot near the baffle. Then the glass box is lowered and placed on the receiving plate, so that the receiving plate supports the glass box. Thus, it is not necessary to hold the glass box continuously during the process of rotating the baffle to close the installation slot, which provides convenience for the operator.
[0024] Preferably, the baffle has a groove on the side near the curtain wall glass, a scraper is movably disposed in the groove, the length direction of the scraper is parallel to the length direction of the crossbeam, and a connecting rope is provided between the scraper and the bottom wall of the groove.
[0025] By adopting the above technical solution, when the baffle rotates away from the installation groove, the baffle gradually tilts. At this time, the scraper slides out of the groove and falls along the curtain wall glass. When it falls, the scraper falls downward with the fireproof coating, which helps to smooth the fireproof coating.
[0026] In summary, this application includes the following beneficial technical effects:
[0027] When a building catches fire, the temperature rises rapidly. Because the fire resistance of the glass box is lower than that of the curtain wall glass, the glass box breaks before the curtain wall glass. By adjusting the baffle through the adjustment mechanism, the mounting groove is opened. Under the action of the fire-retardant coating and the weight of the baffle itself, the baffle rotates away from the mounting groove until it abuts against the limit block. At this time, the side of the baffle closest to the curtain wall glass tilts downward to guide the fire-retardant coating, so that the fire-retardant coating can flow onto the curtain wall glass, providing a certain degree of protection for the curtain wall glass and improving its fire resistance to a certain extent. This makes the curtain wall glass less likely to break in a short time and helps to slow down the spread of fire. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0035] This application discloses a fireproof structure based on a building curtain wall. (Refer to...) Figure 1 and Figure 2 The fire-resistant structure based on the building curtain wall includes a horizontal beam 1, a vertical beam 2, and curtain wall glass 3 fixedly installed between the horizontal beam 1 and the vertical beam 2. An installation groove 4 is provided on the side of the horizontal beam 1 near the lower curtain wall glass 3. The installation groove 4 has a rectangular cross-section, and its length is parallel to the length of the horizontal beam 1. In this embodiment, two installation grooves 4 are symmetrically provided along the curtain wall glass 3. A glass box 5 is movably placed inside the installation groove 4. The glass box 5 is a glass box with certain cracks to facilitate breakage in a fire. The glass box 5 has a rectangular cross-section, and the depth of the installation groove 4 is greater than the thickness of the glass box 5. Fire-retardant coating is stored inside the glass box 5. The quality and fire resistance of the fire-retardant coating can be selected according to actual needs. The fire resistance of the glass box 5 is lower than that of the curtain wall glass 3, causing the glass box 5 to break before the curtain wall glass 3 under the same fire conditions.
[0036] Reference Figure 2 and Figure 3 A baffle 6 is rotatably mounted on the inner wall of the mounting groove 4 on the side away from the curtain wall glass 3. The length direction of the baffle 6 is parallel to the length direction of the crossbeam 1. The baffle 6 is located below the glass box 5. A rotating shaft is coaxially mounted on the baffle 6. The rotating shaft is rotatably mounted on the inner wall of the mounting groove 4 on the side away from the curtain wall glass 3. The rotation axis of the baffle 6 is parallel to the length direction of the crossbeam 1. The baffle 6 rotates in the direction of approaching or moving away from the mounting groove 4. The cross-sectional area of the baffle 6 is adapted to the cross-sectional area of the corresponding mounting groove 4 so that the mounting groove 4 can be closed when the baffle 6 is in a horizontal state. An adjustment mechanism 7 is provided in the crossbeam 1 for adjusting the baffle 6 to close or open the mounting groove 4.
[0037] Reference Figure 4 and Figure 5 Mounting seats 17 are distributed at both ends of the mounting groove 4 along its length. The mounting seats 17 are fixed to the side of the crossbeam 1 near the lower curtain wall glass 3. A groove 18 is provided on the side of the mounting seat 17 near the baffle 6. A limiting block 8 is slidably arranged in the groove 18. The limiting block 8 is located below the rotating shaft of the baffle 6. The sliding direction of the limiting block 8 is parallel to the length direction of the crossbeam 1. The limiting block 8 slides towards or away from the baffle 6. The side of the limiting block 8 away from the glass box 5 is an arc surface, which is inclined upward on the side near the baffle 6. The side of the limiting block 8 near the glass box 5 is a slope, which is inclined downward on the side near the curtain wall glass 3. The slope of the limiting block 8 near the glass box 5 is used to abut against the side of the baffle 6 away from the glass box 5. When the side of the baffle 6 away from the glass box 5 abuts against the side of the limiting block 8 near the glass box 5, the side of the baffle 6 near the curtain wall glass 3 is inclined downward, thereby guiding the fireproof coating onto the curtain wall glass 3.
[0038] Reference Figure 4 and Figure 5 A first spring 10 is provided in the groove 18 to push the limiting block 8 to slide toward the baffle 6. The extension direction of the first spring 10 is parallel to the sliding direction of the limiting block 8. One end of the first spring 10 is fixed on the bottom wall of the groove 18, and the other end is fixed on the side of the limiting block 8 away from the baffle 6.
[0039] In use, push the limiting blocks 8 on both sides away from the baffle 6 by hand to slide them away from the baffle 6, pushing the limiting blocks 8 into the groove 18 and compressing the first spring 10. Then rotate the baffle 6 away from the mounting groove 4 to open the mounting groove 4. Then release the limiting blocks 8, and the first spring 10 pushes the limiting blocks 8 out of the groove 18. Next, place the glass box 5 containing fire-retardant coating into the mounting groove 4, and then rotate the baffle 6 towards the mounting groove 4. The baffle 6 gradually slides relative to the arc surface of the limiting blocks 8 and pushes the limiting blocks 8 towards the groove 18, compressing the first spring 10. When the baffle 6 rotates to above the limiting blocks 8 and disengages from them, the first spring 10 pushes the limiting blocks 8 out of the groove 18. Rotate the baffle 6 to a horizontal position to close the mounting groove 4. The baffle 6 is fixed in position by the adjusting mechanism 7 to close the mounting groove 4, thereby realizing the installation of the glass box 5 and facilitating the protection of the glass box 5 when not in use.
[0040] When a fire occurs, as the temperature rises rapidly, the glass box 5 cracks before the curtain wall glass 3. At this time, the fire-retardant coating inside the glass box 5 flows out. The adjusting mechanism 7 adjusts the baffle 6 to open the mounting groove 4. Under the weight of the baffle 6 and the fire-retardant coating, the baffle 6 rotates away from the mounting groove 4 until the side of the baffle 6 away from the glass box 5 abuts against the inclined surface of the limiting block 8, causing the side of the baffle 6 closest to the curtain wall glass 3 to tilt downward. At this time, the baffle 6 guides the fire-retardant coating. Due to the impact force when the fire-retardant coating flows out, it coats the surface of the curtain wall glass 3, thus providing a certain degree of protection for the curtain wall glass 3. The fire-retardant coating has good fire-retardant properties, which can improve the fire resistance of the curtain wall glass 3, making it less likely to shatter in a fire, and to a certain extent preventing the fire from spreading upward and slowing down the spread of the fire.
[0041] Reference Figure 4 and Figure 5 To facilitate the opening or closing of the mounting groove 4 by adjusting the baffle 6, first grooves 19 are symmetrically provided on the inner walls of both sides of the mounting groove 4 along its length. A fixing rod 20 is fixed on the bottom wall of the first groove 19. The adjustment mechanism 7 includes a plug rod 71 slidably sleeved on the fixing rod 20 and an adjustment component 72 provided on the crossbeam 1. The sliding direction of the plug rod 71 is parallel to the length direction of the crossbeam 1. The plug rod 71 is slidably sleeved on the fixing rod 20, making it difficult for the plug rod 71 to detach from the first groove 19. The plug rod 71 slides towards or away from the baffle 6. The two side walls of the baffle 6 near the plug rod 71 are respectively provided with slots 9 for insertion and engagement with the corresponding plug rod 71. The adjustment component 72 is used to adjust the sliding direction of the plug rod 71 towards or away from the slot 9. When the plug rod 71 is inserted and engaged with the corresponding slot 9, the baffle 6 is in a horizontal state and the mounting groove 4 is closed.
[0042] Reference Figure 2and Figure 5 The bottom wall of the mounting groove 4 has a second groove 21, the length of which is vertically oriented. The second groove 21 is located in the middle of the mounting groove 4. The adjustment assembly 72 includes an adjustment rod 721 slidably disposed in the second groove 21, a pull rope 722 fixedly connected to the adjustment rod 721, a pull member 723 disposed in the second groove 21, and a push member 724 disposed in the first groove 19. The sliding direction of the adjustment rod 721 is vertically oriented. The adjustment rod 721 is located above the glass box 5. The end of the adjustment rod 721 near the glass box 5 is used to abut against the glass box 5. The pull rope 722 and the insertion rod 71 are connected one by one. Correspondingly, one end of the pull rope 722 is fixedly connected to the side of the adjusting rod 721 away from the glass box 5, and the other end slides through the crossbeam 1 and is fixedly connected to the side of the corresponding insert rod 71 away from the baffle 6. The crossbeam 1 is provided with a first channel 22 for the pull rope 722 to slide through. One end of the first channel 22 is connected to the second groove 21, and the other end is connected to the corresponding first groove 19. When the adjusting rod 721 slides toward the direction closer to the glass box 5, the pull rope 722 pulls the insert rod 71 to slide away from the baffle 6. The baffle 6 is provided with a lifting member for pushing the glass box 5 to slide toward the direction closer to the adjusting rod 721.
[0043] Reference Figure 2 and Figure 5 The pull member 723 is used to pull the adjusting rod 721 to slide towards the glass box 5. The pull member 723 includes a tension spring 7231 for pulling the adjusting rod 721 to slide towards the glass box 5. The tension spring 7231 is sleeved on the adjusting rod 721. One end of the tension spring 7231 is fixedly connected to the side of the adjusting rod 721 away from the glass box 5, and the other end is fixedly connected to the inner wall of the second groove 21.
[0044] Reference Figure 2 and Figure 5 The pusher 724 is used to push the insert rod 71 to slide towards the baffle 6. The pusher 724 includes a second spring 7241 for pushing the insert rod 71 to slide towards the baffle 6. The second spring 7241 is movably sleeved on the corresponding fixed rod 20. One end of the second spring 7241 is fixedly connected to the side of the insert rod 71 away from the baffle 6, and the other end is fixedly connected to the bottom wall of the first groove 19. The thrust of the second spring 7241 is less than the tension of the tension spring 7231, and the thrust of the second spring 7241 is greater than the thrust of the first spring 10.
[0045] Reference Figure 3 and Figure 4The lifting component includes a screw 11 threaded through the baffle 6. The rotation axis of the screw 11 is perpendicular to the plane of the baffle 6. The screw 11 is located in the middle of the baffle 6. A clamping strip 23 is rotatably connected to the side of the screw 11 near the glass box 5. The cross-sectional area of the clamping strip 23 is smaller than the cross-sectional area of the glass box 5. The clamping strip 23 is used to abut against the glass box 5.
[0046] When it is necessary to close the mounting slot 4 with the baffle 6, rotate the baffle 6 until the slot 9 is aligned with the insertion rod 71. Then rotate the screw 11 so that the screw 11 drives the clamping strip 23 to move towards the glass box 5 in the mounting slot 4. The clamping strip 23 pushes the glass box 5 to slide towards the adjusting rod 721. Then the glass box 5 gradually comes into contact with the adjusting rod 721 and pushes the adjusting rod 721 to slide away from the baffle 6, stretching the tension spring 7231. At this time, the tension of the pull rope 722 on the insertion rod 71 decreases. The second spring 7241 pushes the insertion rod 71 to move towards the baffle 6, so that the insertion rod 71 is inserted into the slot 9 until the glass box 5 comes into contact with the bottom wall of the mounting slot 4, thus closing the mounting slot 4 with the baffle 6 and fixing the glass box 5 so that the glass box 5 is not prone to unnecessary shaking. When the glass box 5 breaks, it no longer abuts against the adjusting rod 721. At this time, the tension spring 7231 pulls the adjusting rod 721 to slide towards the baffle 6. Since the tension of the tension spring 7231 is greater than the thrust of the second spring 7241, the pull rope 722 pulls the insertion rod 71 to slide away from the baffle 6, causing the insertion rod 71 to disengage from the slot 9. At this time, under the gravity of the baffle 6 and the fireproof coating, the baffle 6 rotates away from the mounting slot 4 to open the mounting slot 4.
[0047] Reference Figure 2 and Figure 3 The mounting groove 4 has two receiving grooves 24 on opposite sides. The arrangement direction of the two receiving grooves 24 is perpendicular to the length direction of the crossbeam 1. The receiving grooves 24 are located above the baffle 6. The distance from the inner wall of the receiving groove 24 away from the baffle 6 to the bottom wall of the mounting groove 4 is greater than the thickness of the glass box 5. A receiving plate 25 is hinged to the inner wall of the receiving groove 24 near the baffle 6. A hinge shaft is coaxially fixed on the receiving plate 25. The hinge shaft rotates on the side of the corresponding receiving groove 24 near the baffle 6. The hinge axis of the receiving plate 25 is parallel to the length direction of the crossbeam 1. The receiving plate 25 is used to receive the glass box 5. The two receiving plates 25 are located on both sides of the screw 11. The receiving plates 25 can rotate into or out of the receiving groove 24. A torsion spring 26 is sleeved on the hinge shaft of the receiving plate 25. The torsion spring 26 is used to drive the receiving plate 25 to rotate out of the receiving groove 24 and abut against the inner wall of the receiving groove 24 near the baffle 6. One end of the torsion spring 26 is fixed on the receiving plate 25, and the other end is fixed on the inner wall of the receiving groove 24. When the glass box 5 is placed on the receiving plate 25, the glass box 5 is disengaged from the adjusting rod 721.
[0048] When it is necessary to place the glass box 5 into the mounting groove 4, align the glass box 5 with the mounting groove 4, move the glass box 5 upward, and the glass box 5 will first slide relative to the arc surface of the limiting block 8 and push the limiting block 8 into the groove 18. Then, it will separate from the limiting block 8 and enter the mounting groove 4. Then, the glass box 5 will gradually come into contact with the receiving plate 25 and push the receiving plate 25 to rotate towards the direction closer to the receiving groove 24, so that the receiving plate 25 rotates into the receiving groove 24. Then, the glass box 5 will separate from the receiving plate 25. Then, the torsion spring 26 will drive the receiving plate 25 to rotate away from the receiving groove 24 to a horizontal position. At this time, the glass box 5 can be lowered so that the glass box 5 is placed on the receiving plates 25 on both sides. The glass box 5 is not in contact with the adjusting rod 721. Then, the baffle 6 can be rotated towards the direction closer to the mounting groove 4. It is not necessary to hold the glass box 5 with your hand all the time, which provides convenience for the operator.
[0049] Reference Figure 2 The inner wall of the mounting groove 4 is covered with a heat insulation layer (not shown in the figure). The heat insulation layer can block the normal solar temperature and facilitate the storage of fireproof coating inside the glass box 5. In the event of a fire, the temperature is much higher than the normal air temperature, and the heat insulation layer cannot block the high temperature, which may lead to the breakage of the glass box 5.
[0050] Reference Figure 2 and Figure 3 A slide groove 12 is provided on the side of the baffle 6 near the curtain wall glass 3. A scraper 13 is movably installed in the slide groove 12. The length direction of the scraper 13 is parallel to the length direction of the crossbeam 1. A connecting rope 14 is fixed between the scraper 13 and the bottom wall of the slide groove 12. Multiple connecting ropes 14 are provided and arranged along the length direction of the scraper 13 to help the scraper 13 fall smoothly. The length of the connecting rope 14 is greater than the height of the curtain wall glass 3.
[0051] When the baffle 6 rotates away from the mounting groove 4 and comes into contact with the limiting block 8, the baffle 6 opens the mounting groove 4. At this time, the baffle 6 tilts and the scraper 13 slides along the slide groove 12 toward the curtain wall glass 3, which enables the scraper 13 to scrape the fireproof coating on the curtain wall glass 3 evenly and accelerate the flow speed of the fireproof coating.
[0052] Reference Figure 4 and Figure 5A transmission rope 27 connects the side of the insertion rod 71 away from the baffle 6 to the corresponding limiting block 8. The transmission rope 27 slides through the crossbeam 1 and the mounting base 17. The crossbeam 1 and the mounting base 17 have a second channel 28 for the transmission rope 27 to slide through. One end of the second channel 28 is connected to the first groove 19, and the other end is connected to the corresponding groove 18. When the insertion rod 71 slides towards the baffle 6, the transmission rope 27 pulls the limiting block 8 towards the groove 18, moving the limiting block 8 into the groove 18, which helps to make the fireproof structure look simple. When the insertion rod 71 slides away from the baffle 6, the tension of the transmission rope 27 on the limiting block 8 decreases, and the first spring 10 pushes the limiting block 8 to slide away from the groove 18 so as to abut against the baffle 6 and limit the rotation angle of the baffle 6.
[0053] The implementation principle of this application embodiment is as follows: During installation, the glass box 5 containing fire-retardant coating is aligned with the mounting groove 4, and the glass box 5 is moved upward. The glass box 5 gradually slides relative to the arc surface of the limit blocks 8 on both sides, pushing the limit blocks 8 to slide towards the corresponding groove 18, so that the limit blocks 8 move into the groove 18. Then the glass box 5 enters the mounting groove 4 and disengages from the limit blocks 8. The first spring 10 pushes the limit blocks 8 to move out of the groove 18. Then the glass box 5 gradually pushes the receiving plate 25 to rotate towards the receiving groove 24 until the glass box 5 moves upward and disengages from the receiving plate 25. At this time, the torsion spring 26 immediately drives the receiving plate 25 to rotate away from the receiving groove 24 until it abuts against the inner wall of the receiving groove 24 near the baffle 6. Then the glass box 5 is gradually released, so that the glass box 5 moves down onto the receiving plate 25. At this time, the glass box 5 does not abut against the adjusting rod 721.
[0054] Then, rotate the baffle 6 towards the mounting groove 4, pushing the scraper 13 to the side of the slide groove 12 away from the curtain wall glass 3. The baffle 6 gradually slides relative to the arc surfaces of the two limiting blocks 8, pushing the limiting blocks 8 into the groove 18, compressing the first spring 10. Then, the baffle 6 disengages from the limiting blocks 8, and the first spring 10 pushes the limiting blocks 8 out of the groove 18. Rotate the baffle 6 to a horizontal position to close the mounting groove 4, aligning the slot 9 with the insertion rod 71, and keeping the scraper 13 still on the side of the slide groove 12 away from the curtain wall glass 3. Then, rotate the screw 11 to drive the clamping strip. 23 is screwed into the glass box 5, causing the glass box 5 to move towards the adjusting rod 721. The glass box 5 gradually moves upward against the adjusting rod 721, and the tension of the pull rope 722 on the insertion rod 71 decreases. The second spring 7241 pushes the insertion rod 71 to move towards the baffle 6. At this time, the transmission rope 27 pulls the limiting block 8 to move towards the groove 18 until the glass box 5 abuts against the bottom wall of the mounting groove 4. The adjusting rod 721 is completely moved into the second groove 21, and the insertion rod 71 is inserted into the slot 9. The limiting block 8 is located in the mounting base 17, thereby realizing the installation and protection of the glass box 5.
[0055] In the event of a fire, as the temperature rises rapidly, glass box 5 cracks before curtain wall glass 3. At this point, the fire-retardant coating inside glass box 5 leaks out. After glass box 5 cracks, the resistance force on adjusting rod 721 decreases. Tension spring 7231 pulls adjusting rod 721 towards the baffle 6, and pull rope 722 pulls insert rod 71 away from baffle 6, causing insert rod 71 to disengage from slot 9. At this time, the tension of transmission rope 27 on limiting block 8 decreases, and first spring 10 pushes limiting block 8 out of groove 18. Then, under the weight of baffle 6 and the fire-retardant coating itself, baffle 6 moves away from mounting groove 4. The direction is rotated until the side of the baffle 6 away from the glass box 5 abuts against the inclined surface of the limiting block 8. Since the side of the baffle 6 closest to the curtain wall glass 3 is tilted downward, the mounting groove 4 is opened, and the fireproof coating on the baffle 6 flows quickly to the curtain wall glass 3. At the same time, the scraper 13 gradually moves towards the direction closest to the curtain wall glass 3 and moves down along the curtain wall glass 3, which helps to spread the fireproof coating on the curtain wall glass 3 evenly. The fireproof coating is applied to the surface of the curtain wall glass 3, which has a certain protective effect on the curtain wall glass 3 and can improve the fire resistance of the curtain wall glass 3, making the curtain wall glass 3 less likely to shatter in a fire and slowing down the spread of fire to a certain extent.
[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
