Description

Technical Field

[0001] This utility model relates to the field of building structure engineering technology, and in particular to a fireproof smoke duct support mechanism for prefabricated buildings. Background Technology

[0002] With the rapid development of prefabricated buildings, fire-resistant flues, as an important component of buildings, have attracted much attention for the stability and fire resistance of their supporting structures. Currently, prefabricated buildings use prefabricated components for rapid assembly, but the supporting structures of fire-resistant flues suffer from problems such as complex installation and insufficient fire resistance. In recent years, with the improvement of building fire protection standards, the development of supporting mechanisms with higher fire resistance and convenient installation has become an urgent need for the industry.

[0003] Traditional support devices have complex structures and require specialized tools for installation, making construction difficult and inefficient. Furthermore, disassembling the support device is difficult during flue maintenance or replacement, increasing maintenance costs and time. The current solution is to reserve sufficient maintenance space in the design, use a flexible connection between the support device and the flue, and set up clearly marked installation interfaces to facilitate quick location and operation by maintenance personnel.

[0004] However, there are still cases where, during a fire, the support device is made of ordinary metal materials, which soften and deform under the high temperature of the fire, losing its support function and causing the flue to lose support, thus creating a safety hazard. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a prefabricated building fireproof flue support mechanism, which aims to improve the problem that the support device in the prior art uses ordinary metal materials, which soften and deform under high temperature in a fire, loses its support function, and causes the flue to lose its support.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a prefabricated building fireproof flue support mechanism, comprising two support plates and a flue shell, wherein multiple fire-resistant steel columns are fixedly connected between adjacent support plates, and a fireproof mechanism is provided between adjacent support plates to improve the fireproof effect of the flue shell; quick-installation mechanisms are provided on the upper and lower sides of the flue shell, and connecting mechanisms are provided on the left and right sides of the top support plate; the fireproof mechanism includes a ceramic fiber felt shell, the outer wall of which is disposed between adjacent support plates, and rock wool boards are fixedly connected to the upper and lower sides of the inner wall of the ceramic fiber felt shell; multiple installation grooves are provided on the opposite sides of the two rock wool boards, and fireproof pads are fixedly connected inside the multiple installation grooves; gel boards are fixedly connected to adjacent sides of the two rock wool boards, and multiple carbon columns are fixedly connected to the opposite sides of the two gel boards; and anti-compression components are respectively provided on the opposite sides of the two rock wool boards.

[0007] The above technical solution enables fireproofing and heat insulation of the outer wall of the flue shell by filling it with ceramic fiber felt. Then, the connection of rock wool board and multiple fireproof pads further improves the fireproofing effect, effectively isolating heat transfer. At the same time, the connection of multiple carbon columns improves the internal toughness of the fireproof structure, thereby effectively preventing the deformation of the frame and avoiding the flue shell from losing support.

[0008] As a further description of the above technical solution: The quick-installation mechanism includes two rotating shafts, with adjacent sides of the two rotating shafts rotatably connected to the upper and lower sides of the flue shell, respectively. A connecting plate is rotatably connected to the outer wall of the rotating shaft, and multiple positioning pins are fixedly connected to the rear side of the connecting plate. Multiple positioning grooves are opened in the middle of the front side of the two support plates, and the rear ends of the multiple positioning pins are respectively engaged with the corresponding positioning grooves. A locking bolt is threaded to the front side of the connecting plate, and the end of the locking bolt is threaded to the front side of the support plate.

[0009] The above technical solution allows the connecting plate to align with the front side of the corresponding support plate after the flue shell is flipped, enabling multiple positioning posts to engage with the positioning grooves, thus achieving rapid installation, simplifying the flue shell installation process, and improving installation efficiency.

[0010] As a further description of the above technical solution: The pressure-resistant component includes multiple pressure-resistant plates, with adjacent sides of the multiple pressure-resistant plates respectively fixedly connected to the opposite sides of the two rock wool boards, and multiple arc-shaped grooves are provided on the opposite sides of the multiple pressure-resistant plates.

[0011] The above technical solution improves the resistance to external pressure by creating the pressure-resistant plate and the arc-shaped groove.

[0012] As a further description of the above technical solution: The connecting mechanism includes multiple connecting seats, with adjacent sides of the multiple connecting seats respectively fixedly connected to the left and right sides of the top support plate, and expansion bolts threadedly connected to the bottom of the connecting seats.

[0013] The above technical solution facilitates the connection and installation of the mechanism at the mounting position by connecting the connecting seat and the expansion bolt.

[0014] As a further description of the above technical solution: The quick-release mechanism also includes two washers, the inner walls of which are respectively fixedly connected to the middle of the corresponding locking bolts.

[0015] The above technical solution reduces the rotational damage to the connecting plate caused by the locking bolts when the gasket is connected.

[0016] As a further description of the above technical solution: The outer wall of the flue shell is disposed on the inner wall of the ceramic fiber felt shell, and the external dimensions of the flue shell match the internal dimensions of the ceramic fiber felt shell.

[0017] The above technical solution improves the compatibility of the connection when the external dimensions of the flue shell match the internal dimensions of the ceramic fiber felt shell.

[0018] As a further description of the above technical solution: The fireproof mechanism also includes two basalt fiberboards, with adjacent sides of the two basalt fiberboards fixedly connected to the opposite sides of the two support plates.

[0019] The above technical solution improves the wear resistance of one side of the support plate by connecting basalt fiberboard.

[0020] As a further description of the above technical solution: The fireproof mats are arranged at equal intervals, and the two rock wool boards are designed symmetrically.

[0021] The above technical solution improves the uniformity of fire protection by arranging multiple fireproof mats at equal intervals.

[0022] This utility model has the following beneficial effects: 1. In this utility model, the filling of ceramic fiber felt shell enables the outer wall of the flue shell to be wrapped and covered, achieving a preliminary fireproof and heat insulation effect. Subsequently, the connection and fixation of rock wool board and multiple fireproof pads further improves the fireproof purpose and effectively isolates the heat transfer. At the same time, the connection of gel board and carbon column improves the internal strength of the fireproof mechanism, thereby effectively preventing the deformation of the frame, extending the service life of the structure, and avoiding the situation where the flue shell loses its support.

[0023] 2. In this utility model, by sliding the flue shell, the connecting plate can be aligned with the front side of the corresponding support plate after flipping, so that multiple positioning columns can be engaged with the positioning groove to achieve the purpose of rapid installation. Then, under the rotation of the locking bolt, the connecting plate can be connected and locked with the support plate, thereby simplifying the installation process of the flue shell and shortening the construction cycle.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a prefabricated building fireproof flue support mechanism, comprising two support plates 1 and a flue shell 3. Multiple fire-resistant steel columns 2 are fixedly connected between adjacent support plates 1, thereby improving the support effect of the frame mechanism and enhancing its stability under high-temperature environments. A fireproof mechanism 4 is provided between adjacent support plates 1 to improve the fireproof effect of the flue shell 3. Quick-installation mechanisms 5 are provided on both the upper and lower sides of the flue shell 3, improving efficiency. Connecting mechanisms 6 are provided on both the left and right sides of the top support plate 1. The fireproof mechanism 4 includes a ceramic fiber felt shell 401, the outer wall of which is provided on both support plates 1. Between adjacent support plates 1, rock wool boards 402 are fixedly connected to the upper and lower sides of the inner wall of the ceramic fiber felt shell 401. This allows multiple fireproof pads 404 to be used in conjunction with the rock wool boards 402 to further improve the fireproof effect. Multiple installation grooves 403 are provided on the opposite sides of the two rock wool boards 402. Fireproof pads 404 are fixedly connected inside the multiple installation grooves 403. Gel boards 405 are fixedly connected to adjacent sides of the two rock wool boards 402. Multiple carbon columns 406 are fixedly connected to the opposite sides of the two gel boards 405. The connection of multiple carbon columns 406 can improve the toughness of the structure and extend the service life of the structure. Anti-compression components 407 are respectively provided on the opposite sides of the two rock wool boards 402. Specifically, multiple fire-resistant steel columns 2 are fixedly connected between the two support plates 1. These fire-resistant steel columns 2, with their high-temperature resistance and high strength, enhance the support capacity of the frame structure, ensuring the stability of the frame under high-temperature conditions. The fireproof mechanism 4 installed between the two support plates 1 has a ceramic fiber felt shell 401 as its core component. The outer wall of this felt shell is installed between the two support plates 1, utilizing the low thermal conductivity of ceramic fibers to initially block heat transfer. Rock wool boards 402 are connected to the upper and lower sides of the inner wall of the ceramic fiber felt shell 401. The non-combustible nature and good thermal insulation of rock wool further enhance the fireproof performance. Multiple mounting grooves 40 are provided on the side of the rock wool board 402 away from the ceramic fiber felt shell 401. 3. The fireproof pad 404 fixed in the groove works in conjunction with the rock wool board 402 to enhance the fireproof effect. The gel board 405 connected to the opposite side of the two rock wool boards 402 assists in heat insulation through its own material properties. The multiple carbon columns 406 connected to the outside of the gel board 405 utilize the high strength and toughness of carbon materials to enhance the overall structural toughness, reduce structural damage caused by high temperature or external force, and extend service life. In addition, the anti-pressure component 407 is set on the side of the two rock wool boards 402 away from the ceramic fiber felt shell 401 to withstand external pressure and ensure the stability of the fireproof mechanism 4. The quick-installation mechanism 5 on the upper and lower sides of the flue shell 3 enables quick installation and disassembly, improving the efficiency of use.

[0028] Reference Figure 1 , Figure 3 and Figure 5 The quick-installation mechanism 5 includes two rotating shafts 501. The adjacent sides of the two rotating shafts 501 are rotatably connected to the upper and lower sides of the flue shell 3, respectively. A connecting plate 502 is rotatably connected to the outer wall of the rotating shaft 501, so that multiple positioning posts 503 can be aligned with the front side of the support plate 1 when the connecting plate 502 rotates. Multiple positioning posts 503 are fixedly connected to the rear side of the connecting plate 502. Multiple positioning grooves 504 are opened in the middle of the front side of the two support plates 1. The rear ends of the multiple positioning posts 503 are respectively engaged with the corresponding positioning grooves 504. Thus, the positioning effect during installation can be improved by the engagement of the positioning posts 503 and the positioning grooves 504. A locking bolt 505 is threadedly connected to the front side of the connecting plate 502. The end of the locking bolt 505 is threadedly connected to the front side of the support plate 1. Then, the construction efficiency of the flue shell 3 can be completed by the rotation of the locking bolt 505. Specifically, two rotating shafts 501 are rotatably connected to the upper and lower sides of the flue shell 3, respectively. The connecting plate 502 rotatably connected to the outer wall of the rotating shaft 501 can rotate around the rotating shaft 501. Rotating the connecting plate 502 allows multiple positioning posts 503 fixedly connected to its rear side to align with multiple positioning slots 504 opened in the middle of the front side of the support plate 1. When the rear ends of the multiple positioning posts 503 are respectively engaged in the corresponding positioning slots 504, the precise positioning of the flue shell 3 during installation is achieved through the cooperation of the positioning posts 503 and the positioning slots 504, reducing installation deviation. The locking bolt 505 threaded on the front side of the connecting plate 502 has its end threadedly connected to the front side of the support plate 1. By rotating the locking bolt 505, the fastening force generated by the thread transmission is used to firmly connect the connecting plate 502 and the support plate 1, thereby fixing the position of the flue shell 3. By operating the process of positioning first and then fastening, the installation steps of the flue shell 3 are simplified, the installation time is reduced, and the construction efficiency of the flue shell 3 is effectively improved.

[0029] Reference Figure 1 , Figure 4 and Figure 5 The pressure-resistant component 407 includes multiple pressure-resistant plates 4071, with adjacent sides of the multiple pressure-resistant plates 4071 respectively fixedly connected to the opposite sides of two rock wool boards 402. Multiple arc-shaped grooves 4072 are provided on the opposite sides of the multiple pressure-resistant plates 4071. The connecting mechanism 6 includes multiple connecting seats 601, with adjacent sides of the multiple connecting seats 601 respectively fixedly connected to the left and right sides of the top support plate 1. Expansion bolts 602 are threadedly connected to the bottom of the connecting seats 601. The quick-installation mechanism 5 also includes two washers 506, with the inner walls of the two washers 506 respectively fixedly connected to the middle of the corresponding locking bolts 505. Specifically, the connection of multiple pressure-resistant plates 4071 reduces the pressure damage to the rock wool board 402 caused by external forces. The opening of multiple arc-shaped grooves 4072 improves the toughness of the pressure-resistant plates 4071. The connection between the connecting seat 601 and the expansion bolt 602 improves the flexibility of the installation position. The connection of multiple washers 506 reduces the rotational damage to the front side of the connecting plate 502 caused by the locking bolt 505.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the flue shell 3 is set on the inner wall of the ceramic fiber felt shell 401, and the external dimensions of the flue shell 3 match the internal dimensions of the ceramic fiber felt shell 401; the fireproof mechanism 4 also includes two basalt fiber boards 408, and the adjacent sides of the two basalt fiber boards 408 are respectively fixedly connected to the opposite sides of the two support plates 1; the multiple fireproof pads 404 are all arranged at equal intervals, and the two rock wool boards 402 are all designed symmetrically; Specifically, by matching the external dimensions of the flue shell 3 with the internal dimensions of the ceramic fiber felt shell 401, the compatibility between the flue shell 3 and the ceramic fiber felt shell 401 can be improved. The connection of the basalt fiber board 408 can improve the compressive and wear-resistant effect on the outer wall of the support plate 1. The multiple fireproof pads 404 are all arranged at equal intervals, so that the fireproof effect can be uniformly improved.

[0031] Working principle: Two support plates 1 are fixedly connected by multiple fire-resistant steel columns 2. The high temperature resistance and high strength of the fire-resistant steel columns 2 enhance the support stability of the frame in high-temperature environments. The multi-layer structure synergistically improves the fire resistance of the flue shell 3. A ceramic fiber felt shell 401 is installed between the two support plates 1, wrapping the outer wall of the flue shell 3. The low thermal conductivity of the ceramic fiber provides initial fireproofing and heat insulation. Rock wool boards 402, connected to the upper and lower sides of the inner wall of the ceramic fiber felt shell 401, further block heat transfer due to their non-combustible nature and excellent heat insulation properties. A fireproof pad is fixed in the mounting groove 403 on the side of the rock wool board 402 away from the ceramic fiber felt shell 401. Board 404, in conjunction with rock wool board 402, further enhances the fireproof effect. Gel board 405 connected to the opposite sides of the two rock wool boards 402 can assist in heat insulation. Multiple carbon columns 406 connected to the outside of gel board 405 enhance the internal strength of fireproof mechanism 4 through their own high strength and toughness, preventing the frame from deforming due to high temperature or external force. The pressure-resistant component 407 set on the side of rock wool board 402 away from ceramic fiber felt shell 401 can withstand external pressure and ensure the stability of fireproof mechanism 4. In addition, the quick-installation mechanism 5 on the upper and lower sides of flue shell 3 facilitates quick installation and disassembly. The connecting mechanism 6 on the left and right sides of the top support plate 1 provides a connection base for other components. All mechanisms work together to ensure the stable operation of flue. Furthermore, by sliding the flue shell 3, the connecting plate 502 is flipped, aligning the multiple positioning posts 503 fixed on its rear side with the multiple positioning slots 504 opened in the middle of the front side of the support plate 1, achieving rapid positioning. After the rear ends of the multiple positioning posts 503 are engaged with the corresponding positioning slots 504, the initial installation connection of the flue shell 3 is completed, reducing installation deviation. The locking bolts 505 threaded on the front side of the connecting plate 502 are threaded at their ends with the front side of the support plate 1. By rotating the locking bolts 505, the fastening force generated by the thread transmission is used to firmly connect the connecting plate 502 and the support plate 1, completing the final fixation of the flue shell 3. Thus, the structure of first positioning by engaging the positioning posts 503 with the positioning slots 504, and then fastening by the locking bolts 505, simplifies the installation process of the flue shell 3, shortens the construction cycle of the flue shell 3, and improves construction efficiency.
