Fireproof structure of high-rise glass curtain wall

Abstract

This utility model relates to the field of fireproof structures, specifically to a fireproof structure for high-rise glass curtain walls, including a fireproof mounting frame for fireproof installation and a rear mounting frame threadedly connected to the rear side of the fireproof mounting frame. This fireproof structure for high-rise glass curtain walls utilizes a first composite expansion strip, a second composite expansion strip, and a spray mechanism. When the glass curtain wall body encounters high temperatures, the first and second composite expansion strips rapidly expand, forming a hard, carbonized heat insulation layer that effectively seals the gaps between the curtain wall and the fireproof mounting frame and the rear mounting frame. Simultaneously, when the temperature is too high, heat enters the glass sphere through the perforations. After the glass sphere breaks due to the high temperature, the piston rod on the rear side loses the obstruction of the glass sphere and, through spring rebound, pushes the piston rod and its tip to puncture the coolant bladder. This causes the coolant bladder to rupture and spray the internal coolant through micro-atomizing nozzles onto the surface of the glass curtain wall body, achieving cooling and fire prevention.

Description

Technical Field

[0001] This utility model relates to the field of fireproof structures, specifically to a fireproof structure for high-rise glass curtain walls. Background Technology

[0002] Fire-resistant structures for high-rise glass curtain walls are passive fire protection systems specifically designed for high-rise buildings. Through the synergistic effect of materials, construction, and physical mechanisms, they prevent the spread of flames, reduce heat radiation transmission, and ensure the stability of the building structure during a fire, thus buying time for evacuation and fire rescue. Their core lies in achieving self-triggered fire protection functions without relying on electronic sensors or active control systems, but rather by utilizing the thermal responsiveness of materials, structural mechanics, and fluid dynamics principles.

[0003] A search revealed a utility model of a high-rise building glass curtain wall structure with announcement number CN216195796U, relating to the field of building technology. This high-rise building glass curtain wall structure includes a basic frame, a connecting column installed on one side of the basic frame, a locking structure installed on one side of the connecting column, an adjustment mechanism installed inside the locking structure, a glass panel installed on the inner side of the locking structure, and sealing gaskets installed at both ends of the locking structure. The locking structure includes an upper fixing column, a lower fixing column at the lower end of the upper fixing column, and a connecting plate installed at one end of both the upper and lower fixing columns. During the installation of the basic frame and glass panel, the locking structure is more time-saving and labor-saving compared to the traditional bolt-fixed method, improving the installation efficiency of the glass panel and basic frame. Furthermore, the adjustment mechanism can be adjusted according to different sized glass panels, facilitating the installation of glass panels of different sizes on the basic frame, making it highly practical.

[0004] The high-rise building glass curtain wall structure in the aforementioned patent lacks a fire-resistant structure, which leads to uncontrolled fire spread, obstructed evacuation, reduced structural stability, and difficulties in fire rescue.

[0005] Therefore, it is necessary to invent a fireproof structure for high-rise glass curtain walls to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a fireproof structure for high-rise glass curtain walls. When the main body of the glass curtain wall encounters high temperatures, the first composite expansion strip and the second composite expansion strip rapidly expand to form a hard carbonized heat insulation layer, effectively sealing the gaps between the curtain wall and the fireproof installation frame and the rear installation frame. At the same time, when the temperature is too high, heat enters the outside of the glass ball through the slots. After the glass ball breaks due to high temperature, the piston rod on the rear side loses the obstruction of the glass ball. Through the spring rebound, it pushes the piston rod and the tip to puncture the coolant bladder, causing the coolant bladder to break open and spray the coolant inside through the micro atomizing nozzle onto the surface of the main body of the glass curtain wall to achieve cooling and fire prevention. This solves the problem in the high-rise building glass curtain wall structure mentioned in the above-mentioned patent in the background art that does not have a fireproof structure, resulting in uncontrolled fire spread, obstructed personnel evacuation, reduced structural stability, and difficulties in fire rescue.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fireproof structure for high-rise glass curtain walls, including a fireproof installation frame for fireproof installation;

[0008] The rear mounting frame is threaded to the rear side of the fireproof mounting frame. The fireproof mounting frame and the rear mounting frame are inlaid with a first composite expansion strip and a second composite expansion strip. The glass curtain wall body is installed inside the fireproof mounting frame and the rear mounting frame.

[0009] The spray mechanism is fixedly installed on the upper rear side of the rear mounting frame for fire prevention and cooling. The spray mechanism includes modular plates, which are fixedly connected to the upper rear side of the rear mounting frame. The rear side of the modular plate has a slot, and glass balls are placed inside the modular plate. A fixing sleeve is fixedly connected to the rear side of the modular plate, and a spring is fixedly installed inside the fixing sleeve. A piston rod is fixedly connected to the front end of the spring, and a pointed tip is fixedly connected to the front end of the piston rod. A coolant bladder is provided inside the modular plate, and a conveying chamber is opened at the lower part of the interior of the modular plate. A micro atomizing nozzle is fixedly installed at the lower end of the conveying chamber.

[0010] Preferably, the first composite expansion strip and the second composite expansion strip are closely attached to the front and rear outer sides of the glass curtain wall body.

[0011] Preferably, the module plates are evenly spaced on the rear side inside the rear mounting frame, and the conveying cavities are evenly spaced on the inner side of the module plates.

[0012] Preferably, the slot is connected to a glass ball inside the module plate, and the glass ball is located between the piston rod and the tip.

[0013] Preferably, the piston rod is slidably connected to the module plate, and the pointed end is in contact with the coolant bladder.

[0014] Preferably, the glass curtain wall body includes an outer glass layer located inside the fireproof mounting frame, a fireproof layer covering the back of the outer glass layer, and an inner glass layer covering the back of the fireproof layer. The outer glass layer is tempered glass, the fireproof layer is made of nano-silicone fireproof adhesive, and the inner glass layer is wired glass.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This invention, through the arrangement of a first composite expansion strip, a second composite expansion strip, and a spraying mechanism, can not only effectively seal the gaps between the curtain wall and the fireproof installation frame and the rear installation frame, but also achieve cooling and fire prevention when exposed to high temperatures. When the glass curtain wall body encounters high temperatures, the first and second composite expansion strips rapidly expand to form a hard carbonized heat insulation layer, effectively sealing the gaps between the curtain wall and the fireproof installation frame and the rear installation frame. At the same time, when the temperature is too high, heat enters the glass ball through the slots. After the glass ball breaks due to high temperature, the piston rod on the rear side loses the obstruction of the glass ball and pushes the piston rod and the tip to puncture the coolant bladder through the spring rebound, causing the coolant bladder to break open and spray the coolant inside onto the surface of the glass curtain wall body through micro atomizing nozzles to achieve cooling and fire prevention.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 A fireproof structure for a high-rise glass curtain wall is shown, including a fireproof mounting frame 1 for fireproof installation;

[0028] The rear mounting frame 3 is threadedly connected to the rear side of the fireproof mounting frame 1. The fireproof mounting frame 1 and the rear mounting frame 3 are inlaid with the first composite expansion strip 2 and the second composite expansion strip 4. The glass curtain wall body 6 is installed inside the fireproof mounting frame 1 and the rear mounting frame 3.

[0029] The spray mechanism 5 is fixedly installed on the upper rear side of the rear mounting frame 3 for fire prevention and cooling. The spray mechanism 5 includes a module plate 501, which is fixedly connected to the upper rear side of the rear mounting frame 3. A slot 502 is formed inside the rear side of the module plate 501. A glass ball 503 is placed inside the module plate 501. A fixing sleeve 504 is fixedly connected to the rear side of the module plate 501. A spring 505 is fixedly installed inside the fixing sleeve 504. A piston rod 506 is fixedly connected to the front end of the spring 505. A pointed tip 507 is fixedly connected to the front end of the piston rod 506. A coolant bladder 508 is provided inside the module plate 501. A conveying chamber 509 is formed at the lower part of the module plate 501. A micro atomizing nozzle 510 is fixedly installed at the lower end. When the glass curtain wall body 6 encounters high temperature, the first composite expansion strip 2 and the second composite expansion strip 4 expand rapidly to form a hard carbonized heat insulation layer, which effectively seals the gap between the curtain wall and the fireproof installation frame 1 and the rear installation frame 3. At the same time, when the temperature is too high, the heat enters the outside of the glass ball 503 through the slot 502. After the glass ball 503 is broken by high temperature, the piston rod 506 on the rear side loses the obstruction of the glass ball 503. The spring 505 rebounds and pushes the piston rod 506 and the tip 507 to puncture the coolant bladder 508, so that the coolant bladder 508 breaks open and sprays the coolant inside through the micro atomizing nozzle 510 onto the surface of the glass curtain wall body 6 to achieve cooling and fire prevention.

[0030] like Figure 2 and Figure 3As shown, the first composite expansion strip 2 and the second composite expansion strip 4 are closely attached to the front and rear outer sides of the glass curtain wall body 6. When the glass curtain wall body 6 is exposed to high temperature, the first composite expansion strip 2 and the second composite expansion strip 4 expand rapidly to form a hard carbonized heat insulation layer, which effectively seals the gap between the curtain wall and the fireproof installation frame 1 and the rear installation frame 3.

[0031] like Figure 3 and Figure 4 As shown, the module plates 501 are evenly distributed on the rear side inside the rear mounting frame 3, and the conveying cavities 509 are evenly distributed inside the module plates 501. Through multiple module plates 501 and multiple conveying cavities 509, the internal coolant can be evenly sprayed onto the curtain wall surface for cooling treatment.

[0032] like Figure 4 As shown, the slot 502 is connected to the glass ball 503 inside the module board 501. The glass ball 503 is located at the front end of the piston rod 506 and the tip 507. The slot 502 can transfer heat into the surface of the glass ball 503. When the glass ball 503 is exposed to high temperature, it will break, so that the piston rod 506 and the tip 507 can extend and retract to puncture the coolant bladder 508.

[0033] like Figure 4 and Figure 5 As shown, the piston rod 506 is slidably connected to the module plate 501, and the tip 507 is in contact with the coolant bladder 508. When the piston rod 506 is no longer blocked by the glass ball 503, it is pushed back by the spring 505 on the rear side, which punctures the coolant bladder 508 with the tip 507, causing the coolant inside the coolant bladder 508 to spray out.

[0034] like Figure 1 and Figure 6 As shown, the main body 6 of the glass curtain wall includes an outer glass layer 601, which is located inside the fireproof mounting frame 1. The back of the outer glass layer 601 is covered with a fireproof layer 602, and the back of the fireproof layer 602 is covered with an inner glass layer 603. The outer glass layer 601 is tempered glass, the fireproof layer 602 is made of nano-silicone fireproof adhesive, and the inner glass layer 603 is wired glass. The tempered glass of the outer glass layer 601 not only enhances impact resistance but also provides fire protection. The fireproof layer 602 in the middle is made of nano-silicone fireproof adhesive, which provides fire protection. Finally, the inner glass layer 603 is made of wired glass to enhance impact resistance and improve the overall structural stability.

[0035] The working principle of this practical system is as follows: First, the glass curtain wall body 6 is placed in front of the rear mounting frame 3 and the second composite expansion strip 4. Then, the fireproof mounting frame 1 is installed on the front side of the rear mounting frame 3 and fixed with bolts. In the event of a fire in daily life, the high temperature causes the internal first composite expansion strip 2 and second composite expansion strip 4 to expand rapidly, forming a hard carbonized heat insulation layer, effectively sealing the gaps between the curtain wall and the fireproof mounting frame 1 and the rear mounting frame 3 to form a fireproof effect. When the temperature is too high, the heat enters the module panel through the slot 502. Inside the glass ball 501, the glass ball 503 is subjected to high temperature and breaks. The piston rod 506 on the rear side is no longer blocked by the glass ball 503. The spring 505 rebounds and pushes the piston rod 506 and the tip 507 to puncture the coolant bladder 508. The coolant bladder 508 is broken and the coolant inside enters multiple delivery chambers 509. It is then sprayed on the surface of the glass curtain wall body 6 through micro atomizing nozzles 510 to achieve cooling and fireproofing treatment. In this way, the use process of the fireproof structure of the high-rise glass curtain wall is completed.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
