Description

Technical Field

[0001] This utility model relates to the field of curtain wall buildings, specifically a fireproof sealing device for curtain wall buildings. Background Technology

[0002] A curtain wall is the exterior wall cladding of a building. It is a lightweight wall structure with decorative effects commonly used in modern large and high-rise buildings. A curtain wall consists of panels and a supporting structural system. It has a certain displacement capacity relative to the main structure or a certain deformation capacity. It is a building envelope structure or decorative structure that does not bear the function of the main structure. In the field of construction, with the widespread application of curtain wall buildings, fire safety has become a critical issue.

[0003] A search revealed an existing patent (publication number: 202121295243.4) that discloses a fire-stopping structure between curtain wall layers, including a floor slab and a fire-stopping structure. A steel pipe shell assembly is pre-embedded in the top of the floor slab, and a water supply pipe is installed inside the steel pipe shell assembly. Multiple nozzles are installed at the bottom of the water supply pipe. While this patented technology reduces costs through the use of a web and offers better fire-stopping performance, it suffers from a drawback: the fixing mechanism needs to be inserted between the decorative curtain wall and the building's exterior wall for fixation. This requires auxiliary tools or manual support for placement before fixing, making the process cumbersome and difficult to implement.

[0004] Therefore, those skilled in the art have provided a fire-stopping device for curtain wall buildings to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical problems to be solved To address the shortcomings of existing technologies, this application provides a fire-stopping device for curtain wall buildings, which solves the problem that when fixing the curtain wall to the building, external tools or manpower are needed to support the curtain wall before it can be connected to the building through the fixing mechanism, resulting in a cumbersome process and difficulty in installation and fixing.

[0006] 2. Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A fire-stopping device for curtain wall buildings includes a building wall and a curtain wall body. A vertical blocking body is provided on the side of the building wall, and a horizontal blocking body is fixedly connected to both ends of the vertical blocking body. A groove is formed on the side of the horizontal blocking body away from the vertical blocking body. The groove of the horizontal blocking body is trapezoidal in shape. A first fireproof layer is fixedly connected inside the groove of the horizontal blocking body. A second fireproof layer is fixedly connected to the side of the first fireproof layer. A third fireproof layer is fixedly connected to the side of the second fireproof layer. Fixing plates are fixedly connected to the four corners of the side of the curtain wall body. Limiting blocks are fixedly connected to the sides of the fixing plates. Fixing frames are provided on both the left and right sides of the limiting blocks, and limiting rods are slidably connected inside the fixing frames. With the above technical solution, when fixing the curtain wall body to the building wall, only pushing the curtain wall body is needed to initially fix it, thereby limiting the position of the curtain wall body. Then, the curtain wall body can be reinforced a second time by external fixing mechanisms. This not only solves the problem that fixing the curtain wall to the building requires external tools or manpower to support the curtain wall before it can be connected to the building by fixing mechanisms, which makes the process cumbersome and difficult to install, but also allows for a second limiting of the curtain wall body, preventing the external fixing mechanisms from deforming under high temperatures, which could weaken the fixation of the curtain wall body and cause it to fall off.

[0007] Furthermore, the vertical plug body has multiple threaded holes inside, and the side of the building wall has multiple threaded holes. The vertical plug body is fixedly connected to the building wall through the threaded holes and expansion bolts. The vertical plug body and the horizontal plug body are fixed by welding. Through the above technical solutions, the vertical blockage body can provide stable support for the entire sealing body, preventing the sealing body from shifting or shaking due to external forces or factors such as thermal expansion and contraction, ensuring the stability of the sealing body between the curtain wall body and the building wall, and guaranteeing the reliability of fireproof sealing.

[0008] Furthermore, the first fireproof layer is made of an elastic fireproof sealing strip, the second fireproof layer is made of a ceramic fiber fireproof blanket, and the third fireproof layer is made of an expandable graphite sealing strip. Through the above technical solutions, the elastic fireproof sealing strip is tightly embedded in the groove due to its own elasticity, and its outer surface protrudes from the groove, closely adhering to the surface of the curtain wall body and the building wall to prevent air circulation. The ceramic fiber fireproof blanket can continuously block heat transfer, and the expandable graphite sealing strip can expand under high temperature conditions to achieve self-adaptive sealing.

[0009] Furthermore, the side of the transverse block is provided with a positioning frame, the positioning frame is L-shaped, and the positioning frame has multiple threaded holes inside. The interior of the building wall has multiple threaded holes, and the positioning frame is fixedly connected to the building wall through the threaded holes and expansion bolts. Through the above technical solution, the positioning frame can limit and fix multiple fireproof layers, ensuring that the positions of multiple fireproof layers fit the horizontal block.

[0010] Furthermore, the interior of the vertical block has multiple vent holes, and each end of the vent hole is provided with a filter screen. The filter screen is fixedly connected to the vertical block and is made of fire-resistant material. The filter screen is attached to the vertical block with high-temperature resistant adhesive. Through the above technical solution, the vents ensure that their function of balancing air pressure is not affected, and the filter prevents smoke and sparks from passing through the vents, thereby improving the fire resistance of the entire fireproof sealing device and reducing the spread of fire hazards.

[0011] Furthermore, the fixing plate is fixedly connected to the curtain wall body by bolts and threaded holes, and a push block is fixedly connected to the side of the limiting block away from the fixing plate. The push block is triangular in shape. Through the above technical solution, the pusher can push the limiting rod to move, so that the limiting block enters between the two limiting rods and is limited and fixed by the limiting rods.

[0012] Furthermore, the fixing frame has threaded holes inside, and the fixing frame is fixedly connected to the building wall through the threaded holes and expansion bolts. The fixing frame is L-shaped. Through the above technical solution, the fixing frame can be fixed to the building wall, and then the curtain wall body is initially limited, completing the limitation before fixing the curtain wall body and the secondary fixing of the curtain wall body.

[0013] Furthermore, a baffle is fixedly connected to one end of the limiting rod, a spring is sleeved on the outside of the limiting rod, and the baffle and the fixing frame are fixedly connected to both ends of the spring, respectively. A groove adapted to the limiting rod is opened inside the limiting block. Through the above technical solution, the spring can pull the baffle to move, thereby moving the limiting rod into the limiting block and completing the initial fixation between the curtain wall body and the building wall.

[0014] 3. Beneficial effects This utility model provides a fireproof sealing device for curtain wall buildings. It has the following beneficial effects: 1. This utility model provides a fireproof sealing device for curtain wall buildings. Through the arrangement of a fixing plate, fixing frame, limiting rod, spring, limiting block and push block, the device can initially fix the curtain wall body to the building wall by simply pushing the curtain wall body, thereby limiting the position of the curtain wall body. Then, the curtain wall body can be reinforced by an external fixing mechanism. This solves the problem that fixing the curtain wall to the building requires external tools or manpower to support the curtain wall before it can be connected to the building by the fixing mechanism, which makes the process cumbersome and difficult to install. It also provides secondary limiting of the curtain wall body, preventing the external fixing mechanism from deforming under high temperature, which would weaken the fixation of the curtain wall body and cause the curtain wall body to fall off.

[0015] 2. This utility model provides a fireproof sealing device for curtain wall buildings. Through the arrangement of horizontal and vertical blocking bodies, a first fireproof layer, a second fireproof layer, a third fireproof layer, ventilation holes, and a filter, the structure of the device is stable. When sealing the curtain wall body, it can horizontally cover the gaps. Even after the position of the curtain wall body shifts, it can still effectively prevent the leakage of air and smoke. It avoids the fact that some fireproof components are prone to flowing at high temperatures, losing their sealing function, and lacking durability, requiring frequent replacement and maintenance, which increases building maintenance costs and safety hazards.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific implementation method 1: Please see Figure 1 , Figure 2 , Figure 3 This embodiment of a fire-stopping device for a curtain wall building includes a building wall 1 and a curtain wall body 2. A vertical blocking body 3 is provided on the side of the building wall 1, and horizontal blocking bodies 4 are fixedly connected to both ends of the vertical blocking body 3. A groove is formed on the side of the horizontal blocking body 4 away from the vertical blocking body 3. The groove of the horizontal blocking body 4 is trapezoidal in shape. A first fireproof layer 5 is fixedly connected inside the groove of the horizontal blocking body 4. A second fireproof layer 6 is fixedly connected to the side of the first fireproof layer 5, and a third fireproof layer 7 is fixedly connected to the side of the second fireproof layer 6. Fixing plates 15 are fixedly connected to the four corners of the side of the curtain wall body 2. Limiting blocks 16 are fixedly connected to the sides of the fixing plates 15. Fixing blocks 16 are provided on both the left and right sides of the limiting blocks 16. The frame 11 has a sliding connection to a limit rod 12 inside. The fixing plate 15 is fixedly connected to the curtain wall body 2 by bolts and threaded holes. The limit block 16 is fixedly connected to a push block 17 on the side away from the fixing plate 15. The push block 17 is triangular in shape. The fixing frame 11 has a threaded hole inside. The fixing frame 11 is fixedly connected to the building wall 1 by the threaded hole and expansion bolts. The fixing frame 11 is L-shaped. A baffle 13 is fixedly connected to one end of the limit rod 12. A spring 14 is sleeved on the outside of the limit rod 12. The two ends of the spring 14 are fixedly connected to the baffle 13 and the fixing frame 11, respectively. The limit block 16 has a groove inside that matches the limit rod 12.

[0020] This embodiment of a fireproof sealing device for curtain wall buildings, through the arrangement of a fixing plate 15, a fixing frame 11, a limiting rod 12, a spring 14, a limiting block 16, and a push block 17, allows the device to initially fix the curtain wall body 2 to the building wall 1 simply by pushing the curtain wall body 2, thereby limiting the position of the curtain wall body 2. Then, an external fixing mechanism can be used for secondary reinforcement of the curtain wall body 2. This solves the problem of the need for external tools or manpower to support the curtain wall before it can be connected to the building through a fixing mechanism, which is cumbersome and difficult to install. It also provides secondary positioning of the curtain wall body 2, preventing the external fixing mechanism from deforming under high temperatures, which could weaken the fixation of the curtain wall body 2 and cause it to detach.

[0021] The working principle of the above embodiment is as follows: In use, the vertical block 3 is fixed to the building wall 1. During fixing, expansion bolts are placed inside the vertical block 3 through the threaded holes inside the vertical block 3 and the threaded holes in the building wall 1 to fix the vertical block 3. After fixing, it is fixed to the fixing bracket 11 with bolts. Then, the fixing plate 15 is fixed to the curtain wall body 2 with bolts. After fixing, the operator moves the curtain wall body 2 so that the limiting block 16 enters between two adjacent fixing brackets 11. When entering, the push block 17 enters between two adjacent limiting rods 12 and pushes the two... The limiting rod 12 moves, and then the limiting block 16 enters the interior of the two fixing brackets 11 and continues to push the limiting rod 12 to prevent it from moving. When the inner groove of the limiting block 16 moves to the position of the limiting rod 12, the spring 14 continues to pull the baffle 13 to move, thereby moving the limiting rod 12. Then the limiting rod 12 moves into the groove of the limiting block 16, thereby limiting and fixing the limiting block 16, thus completing the initial limiting of the curtain wall body 2. After that, the staff can use the external fixing mechanism to perform secondary reinforcement and limiting of the curtain wall, thereby completing the installation of the curtain wall body 2. Specific implementation method 2: Please see Figure 4 , Figure 5 In this embodiment, a fireproof sealing device for a curtain wall building is provided. The vertical blocking body 3 has multiple threaded holes inside, and the building wall 1 has multiple threaded holes on its side. The vertical blocking body 3 is fixedly connected to the building wall 1 through the threaded holes and expansion bolts. The vertical blocking body 3 and the horizontal blocking body 4 are fixed together by welding. The first fireproof layer 5 is made of elastic fireproof sealing strip, the second fireproof layer 6 is made of ceramic fiber fireproof blanket, and the third fireproof layer 7 is made of expandable graphite sealing strip. The side of the horizontal blocking body 4 is provided with a positioning frame 8, which is L-shaped and has multiple threaded holes inside. The building wall 1 also has multiple threaded holes inside. The positioning frame 8 is fixedly connected to the building wall 1 through the threaded holes and expansion bolts. The vertical blocking body 3 has multiple ventilation holes 9 inside, and filter screens 10 are provided at both ends of each ventilation hole 9. The filter screens 10 are fixedly connected to the vertical blocking body 3 and are made of fireproof material. The filter screens 10 are adhered to the vertical blocking body 3 with high-temperature resistant adhesive.

[0023] This embodiment of a fire-resistant sealing device for curtain wall buildings is characterized by the following: through the arrangement of horizontal blocking body 4, vertical blocking body 3, first fireproof layer 5, second fireproof layer 6, third fireproof layer 7, ventilation holes 9, and filter screen 10, the structure of the device is stable. When sealing the curtain wall body 2, it can horizontally cover the gaps. Even after the position of the curtain wall body 2 shifts, it can still effectively prevent the leakage of air and smoke. This avoids the fact that some fire-resistant components are prone to flowing at high temperatures, losing their sealing function, and having insufficient durability, requiring frequent replacement and maintenance, which increases building maintenance costs and safety hazards.

[0024] The working principle of the above embodiment is as follows: In use, the first fireproof layer 5 enters the groove of the horizontal block 4. Since the first fireproof layer 5 is an elastic fireproof sealing strip, it makes initial fixed contact with the horizontal block 4 through elasticity. Then, the second fireproof layer 6 is fixed to the first fireproof layer 5. After the fixing is completed, the third fireproof layer 7 is fixed to the second fireproof layer 6. Then, the positioning frame 8 is fixed to the building wall 1 by expansion bolts. After fixing, the positioning frame 8 provides limiting support for the third fireproof layer 7. Then, the curtain wall body 2 is fixed to the building wall 1. After fixing, due to the third fireproof layer 7 is an expandable graphite sealing strip. The third fireproof layer 7 is tightly attached to the curtain wall body 2 and the building wall 1 to seal the gaps. In the event of a fire, the first fireproof layer 5, the second fireproof layer 6 and the third fireproof layer 7 of different materials work together to block high-temperature smoke and prevent fire at the fire location. At this time, the filter 10 allows the air to circulate slowly on both sides of the vertical block 3, keeping the air pressure balanced. This prevents smoke or flames from flowing abnormally through the gaps due to excessive air pressure difference, enhances the reliability of the fireproof sealing, and prevents the air pressure from gradually increasing and potentially breaking through the sealing material, causing the fire to spread.
