Description

Technical Field

[0001] The invention relates to the technical field of fireproof equipment, in particular to a fireproof steel partition based on composite nano-silicon glass. Background Art

[0002] Fireproof steel partitions can withstand direct attack of flames for a certain period of time (such as 1 hour, 2 hours, etc.) without losing their integrity, effectively limiting the spread of fire. At the same time, the high strength of steel itself means that even in high temperature environments, fireproof steel partitions can still maintain a certain degree of structural stability, providing the necessary support for buildings and effectively blocking fires.

[0003] Composite nano-silicon glass is usually made of multiple layers of glass and inorganic expandable nano-silicon fireproof adhesive through a special process. Nano-silicon fireproof adhesive is a special fireproof material that is transparent at room temperature, but expands and carbonizes when exposed to high temperatures, forming a protective layer with excellent thermal insulation properties.

[0004] A Chinese patent with application number 201910316468.4 discloses a glass fireproof partition, comprising a first fireproof glass and a second fireproof glass; a first frame, which is arranged on a first side of the first fireproof glass and the second fireproof glass; and a second frame, which is arranged on a second side of the first fireproof glass and the second fireproof glass; wherein, a fastener is included between the first frame and the second frame, and when the fastener applies a longitudinal force between the first frame and the second frame, a lateral force is applied to the first frame and / or the second frame, thereby improving the sealing between the frame and the fireproof glass, and indirectly improving the fire protection level of the glass fireproof partition.

[0005] However, since fireproof gaskets have strong expansion characteristics, they often encounter problems such as local expansion and difficulty in accurately controlling the amount of expansion in actual use. Local expansion will cause uneven expansion, resulting in uneven pressure distribution on the sealing surface, ultimately affecting the sealing effect. At the same time, excessive expansion may cause excessive pressure on the frame and glass, causing structural deformation or damage. Summary of the invention

[0024] Compared with the existing known technologies, the technical solution provided by the present invention has the following significant effects:

[0025] 1. Through the arrangement of expansion components and auxiliary sealing mechanisms, if a fire occurs, the thermal expansion liquid continues to expand as the temperature rises. After being transmitted by the movable plate, support rod, connecting plate and sleeve, the second elastic member is further compressed. The movable plate cooperates with the second elastic member to apply appropriate pre-compression force to the fireproof gasket. When the fireproof gasket expands due to heat, it can expand more evenly at high temperature to prevent sealing problems caused by uneven pressure on the sealing surface. Even when the fireproof gasket is deformed or even slowly melted at high temperature, the movable plate and the second elastic member can still continue to apply pressure to the fireproof gasket to prevent problems such as poor sealing.

[0026] 2. Through the arrangement of the expansion assembly and the auxiliary sealing mechanism, when the expansion force of the fireproof gasket is large, the movable plate and the second elastic member can absorb the excess expansion force, thereby preventing the fireproof gasket from causing structural deformation or even damage to the first connecting frame and the composite nano-silicon glass.

[0027] 3. Through the arrangement of the isolation component, the expansion component, the limiter and the sprayer, as the thermal expansion liquid continues to expand, the conical component continuously applies downward pressure to the connecting ring, and finally applies the downward pressure to the piston ring. When the downward pressure of the piston ring breaks through the limiter, the medium in the outer cavity quickly enters the inner cavity, and the fire extinguishing agent enters the sprayer from the three-way pipe and is finally sprayed out from the spray hole. The sprayed fire extinguishing agent isolates the surrounding side of the first connecting frame from the air to prevent the spreading fire from directly acting on the fireproof partition, which not only further extends the fireproof life of the first connecting frame, but also isolates the air at the connection between the composite nano-silicon glass and the first connecting frame, thereby increasing the service life of the first fireproof gasket and cooperating with the auxiliary sealing mechanism to enhance the sealing and smoke barrier properties of the connection between the two.

[0028] 4. By limiting the diameter of the spray hole, most of the fire extinguishing agent is sprayed on the side close to the fire source, and a small part of the fire extinguishing agent is sprayed on the connection between the composite nano-silicon glass and the first connecting frame, thereby improving the utilization rate of the fire extinguishing agent, enhancing the air isolation effect around the first connecting frame, and further extending the fire protection life of the first connecting frame.

[0029] 5. Through the arrangement of guide parts and the like, when the fire extinguishing agent is sprayed out from the spray hole, the guide parts guide the spraying direction of the fire extinguishing agent, so that multiple streams of the sprayed fire extinguishing agent form a spiral structure, and the spray barrel begins to rotate under the action of the guide parts and the fire extinguishing agent. Due to the action of centrifugal force, the initial velocity of the fire extinguishing agent sprayed out from the spray hole is further increased, thereby increasing the coverage area of ​​the fire extinguishing agent and improving the effective action area of ​​the isolation component on the first connecting frame.

DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] Embodiment 1

[0054] Since fireproof gaskets have strong expansion characteristics, they often encounter problems such as local expansion and difficulty in accurately controlling the expansion amount in actual use. Local expansion will cause uneven expansion, making the pressure distribution on the sealing surface of the fireproof glass and the frame uneven, affecting the sealing effect. At the same time, excessive expansion may produce excessive pressure on the frame and glass, which may cause structural deformation or damage in severe cases. In response to the above problems, this embodiment proposes a fireproof steel partition based on composite composite nano-silicon glass.

[0055] Depend on Figures 1 to 3 A composite nano-silicon glass 1 and a connecting component are provided, wherein the connecting component is used to connect two adjacent composite nano-silicon glasses 1 into one, wherein the composite nano-silicon glass 1 includes two or more layers of glass and one or more layers of nano-silicon fire retardant adhesive. The connecting component includes a first connecting frame 2 and a second connecting frame 3, wherein the first connecting frame 2 is arranged on a side between two adjacent composite nano-silicon glasses 1 where fire is prone to occur, and the second connecting frame 3 is arranged on the other side and opposite to the first connecting frame 2, and further includes a seal 4, an expansion component 5, an auxiliary sealing mechanism 6 and a fastener 7.

[0056] It should be noted that the side prone to fire is mainly where a large number of electrical equipment or flammable materials are gathered, such as offices or storage rooms; at the same time, the first connecting frame 2 and the second connecting frame 3 are matched differently for different places of use. If there are factors prone to fire on both sides of the partition, the connecting component is two symmetrically distributed first connecting frames 2, and the composite nano-silicon glass 1 is located between the two first connecting frames 2.

[0057] refer to Figure 2 and Figure 3 As shown, the seal 4 is arranged between the connecting component and the composite nano-silicon glass 1, and the seal 4 can expand at high temperature. The seal 4 includes a first sealing gasket 41 and a second sealing gasket 42. The first sealing gasket 41 and the second sealing gasket 42 are both made of fireproof materials, such as expanded graphite gaskets.

[0058] refer to Figure 3 and Figure 5 As shown, the first connecting frame 2 includes a shell 21 having a first mounting groove 22 , one end of the first sealing gasket 41 is clamped in the first mounting groove 22 , and the other end is in contact with the composite nano-silicon glass 1 .

[0059] refer to Figure 3 As shown, the second connecting frame 3 includes a glass pressing plate 31, which has a second mounting groove. One end of the second sealing gasket 42 is clamped in the second mounting groove, and the other end is in contact with the composite nano-silicon glass 1. The side of the glass pressing plate 31 away from the second sealing gasket 42 is clamped with an exterior panel 32.

[0060] refer to Figure 3 As shown, the fastener 7 is used to connect the first connecting frame 2 and the second connecting frame 3. The fastener 7 includes a bolt 71 and a nut 72. The bolt 71 penetrates the second connecting frame 3 and the first sealing gasket 41 and extends into the first mounting groove 22. The nut 72 is arranged in the first mounting groove 22 and is threadedly connected to the bolt 71.

[0061] refer to Figure 2 As shown, the expansion assembly 5 is disposed in the first connecting frame 2, and when the first connecting frame 2 is subjected to high temperature, the expansion assembly 5 can expand.

[0062] refer to Figure 4 and Figure 6 As shown, the expansion assembly 5 includes a liquid storage portion 51 located on the inner wall of the shell 21 away from the first mounting groove 22, and a heat expansion liquid is arranged in the liquid storage portion 51. Two mounting plates 52 are fixedly connected to the inner wall of the shell 21 and are respectively located on the upper and lower sides of the liquid storage portion 51. A moving plate 53 in contact with the liquid storage portion 51 is slidably connected between the two mounting plates 52. The four corners of the moving plate 53 away from the liquid storage portion 51 are respectively fixedly connected to the first elastic member 54. The first elastic member 54 includes a mounting rod fixedly connected to the moving plate 53. The shell A mounting block is fixedly connected to the inner wall of 21, the mounting rod is slidably connected to the mounting block, and a pre-tightening spring is coaxially sleeved on the mounting rod, one end of the pre-tightening spring is connected to the movable plate 53, and the other end is connected to the mounting block. The first elastic member 54 has a certain pre-tightening force on the movable plate 53 to maintain the shape of the liquid storage portion 51 and prevent uneven distribution of the thermal expansion liquid in the liquid storage portion 51. A support rod 55 is fixedly connected to the side of the movable plate 53 away from the liquid storage portion 51, and a connecting plate 56 is fixedly connected to the end of the support rod 55 away from the movable plate 53.

[0063] refer to Figure 7 As shown, the auxiliary sealing mechanism 6 is arranged in the first connecting frame 2 and cooperates with the expansion component 5. When encountering high temperature, the expansion component 5 can expand and enable the auxiliary sealing mechanism 6 to strengthen the extrusion force on the sealing member 4.

[0064] refer to Figure 7 and Figure 8As shown, the auxiliary sealing mechanism 6 includes two through holes 61 opened on both sides of the shell 21, and the two through holes 61 are respectively located on both sides of the first mounting groove 22. A movable plate 62 in contact with the first sealing gasket 41 is slidably connected in the through hole 61. The thickness of the movable plate 62 is greater than the thickness of the through hole 61. A connecting rod 63 is fixedly connected to the side of the movable plate 62 away from the first sealing gasket 41. A positioning plate 64 is fixedly connected to the inner wall of the shell 21. A sleeve 65 is threadedly connected to the positioning plate 64. One end of the connecting rod 63 away from the movable plate 62 slides in the sleeve 65. A second elastic member 66 is coaxially arranged between the sleeve 65 and the movable plate 62. The second elastic member 66 is a strong spring. The strong spring is coaxially sleeved on the connecting rod 63. A fixed plate is coaxially fixed to one end of the sleeve 65 close to the connecting rod 63. One end of the strong spring is connected to the fixed plate, and the other end is connected to the movable plate 62.

[0065] refer to Figure 8 As shown, a threaded groove matching the positioning plate 64 is provided on the outer wall of the sleeve 65, a spiral track 67 is provided at one end of the sleeve 65 away from the connecting rod 63, and connecting holes matching the sleeve 65 are respectively provided at both ends of the connecting plate 56, and connecting blocks matching the spiral track 67 are arranged in the connecting holes.

[0066] During use, first determine the matching method of the connecting components according to the application scenario. If the fire partition is used to isolate the office from the fire passage or corridor, because the fire passage and corridor usually do not have electrical equipment or flammable items, the connecting component can be a combination of a first connecting frame 2 and a second connecting frame 3. The first connecting frame 2 is located on one side of the office. If there are factors that are prone to fire on both sides of the fire partition, then the connecting component is a combination of two first connecting frames 2. The two first connecting frames 2 are symmetrically distributed and the composite nano-silicon glass 1 is located between the two first connecting frames 2.

[0067] After the fireproof partition is installed, if a fire occurs, the heat-expanding liquid in the liquid storage part 51 gradually expands as the temperature rises, the liquid storage part 51 is deformed and causes the movable plate 53 to overcome the elastic force of the first elastic member 54 and slide between the two mounting plates 52, and the support rod 55 drives the connecting plate 56 to slide toward the side close to the sleeve 65. Under the action of the spiral track 67 and the connecting plate 56, the sleeve 65 rotates. At this time, the sleeve 65 and the positioning plate 64 are relatively displaced, and the sleeve 65 squeezes the second elastic member 66, so that the second elastic member 66 is further compressed, and the movable plate 62 has a stronger pressing force on the first sealing gasket 41.

[0068] Through the arrangement of the expansion component 5 and the auxiliary sealing mechanism 6, if a fire occurs, the thermal expansion liquid continues to expand as the temperature rises, and is further compressed through the transmission of the movable plate 53, the support rod 55, the connecting plate 56 and the sleeve 65. The second elastic member 66 is further compressed, and the movable plate 62 cooperates with the second elastic member 66 to apply an appropriate pre-compression force to the fireproof gasket. When the fireproof gasket expands when heated, it can expand more evenly at high temperatures to prevent sealing problems caused by uneven pressure on the sealing surface; when an inferior fireproof gasket is deformed or even slowly melted at high temperatures, the movable plate 62 and the second elastic member 66 can also continue to apply pressure to the fireproof gasket to prevent problems such as poor sealing. When the expansion force of the fireproof gasket is large, the movable plate 62 and the second elastic member 66 can offset the excess expansion force to prevent the fireproof gasket from causing structural deformation or even damage to the first connecting frame 2 and the composite nano-silicon glass 1.

[0069] Embodiment 2

[0070] The main functions of the fireproof partition are fire prevention, heat insulation and smoke barrier. In the event of a fire, the fireproof partition itself is also a supporting member. In order to increase the supporting time of the fireproof partition, and on this basis, the sealing and smoke barrier properties of the connection between the composite nano-silicon glass 1 and the first connecting frame 2 are improved.

[0071] refer to Fig. 9 As shown, it also includes an isolation component 8, which is located in the first connecting frame 2 and cooperates with the expansion component 5. When the thermal expansion liquid expands to a preset position, the isolation component 8 can be triggered and spray the fire extinguishing agent to the outside of the first connecting frame 2.

[0072] refer to Fig. 9 , Fig.10 and Fig.11 As shown, further supplementing the structure of the isolation component 8 is that a support plate 23 is fixed in the shell 21, and the isolation component 8 includes a cylinder 81 fixed on the support plate 23, and a cylindrical partition 82 is coaxially fixed in the cylinder 81, and the partition 82 divides the cylinder 81 into an inner cavity 811 and an outer cavity 812 that are interconnected, and a fire extinguishing agent is arranged in the inner cavity 811, and the top of the inner cavity 811 is conical, so as to facilitate the fire extinguishing agent to be sprayed out from the top of the cylinder 81, and a piston ring 83 that slides up and down is coaxially arranged in the outer cavity 812, and a third elastic member 84 is arranged between the piston ring 83 and the bottom of the cylinder 81, and the third elastic member 84 is a telescopic spring, and the elastic force of the telescopic spring is relatively large, and a piston plate 85 that slides up and down is coaxially arranged at the bottom of the inner cavity 811, and a plurality of circumferentially evenly distributed limiting members 86 are arranged on the inner wall of the outer cavity 812, and the piston ring 83 contacts the limiting members 86.

[0073] To supplement the structure of the limit member 86, the limit member 86 includes a limit column slidably connected to the inner wall of the outer cavity 812, and a corresponding limit hole is opened on the inner wall of the outer cavity 812. The limit column slides in the limit hole and is connected to the limit hole through a limit spring. The contact surface between the limit column and the piston ring 83 is an arc surface. When the downward pressure of the piston ring 83 is greater than the lateral force of the limit column, the limit column shrinks into the limit hole and the piston ring 83 moves downward rapidly.

[0074] refer to Fig. 9 and Fig.10 As shown, a three-way pipe 87 connected to the inner cavity 811 is coaxially arranged on the top of the cylinder 81, one end of the three-way pipe 87 is connected to the inner cavity 811, and the pipe diameter matches the minimum diameter of the cone, and spraying parts 88 are respectively arranged on both sides of the first connecting frame 2, and the two spraying parts 88 are respectively connected to the other two ends of the three-way pipe 87 through hoses, and a plurality of circumferentially evenly distributed positioning rods 89 are slidably connected to the top of the cylinder 81, and one end of the positioning rod 89 located inside the cylinder 81 contacts the piston ring 83, and the other ends of the plurality of positioning rods 89 are fixedly connected to the same connecting ring 891, and a conical part 892 is coaxially fixed on the support rod 55, and the conical surface of the conical part 892 contacts the connecting ring 891. In the present embodiment, the conical part 892 is a conical block, and in other embodiments, the conical part 892 may be a triangular block, and the cross-section of the triangular block is a right triangle, and its hypotenuse contacts the connecting ring 891.

[0075] refer to Fig.12 As shown, the spray member 88 includes a cylindrical spray barrel 881, a cavity is formed inside the spray barrel 881, a connecting pipe 882 connected to the cavity is coaxially fixed to the side of the spray barrel 881 close to the shell 21, a mounting hole matching the connecting pipe 882 is provided on the side wall of the shell 21, a plurality of circumferentially evenly distributed spray holes 883 are provided on the circumferential side of the spray barrel 881, and the connecting pipe 882 is connected to the three-way pipe 87 through a hose.

[0076] During use, if a fire occurs, the thermal expansion liquid in the liquid storage portion 51 gradually expands as the temperature rises, the liquid storage portion 51 is deformed and causes the movable plate 53 to overcome the elastic force of the first elastic member 54 and slide between the two mounting plates 52, and the support rod 55 drives the connecting plate 56 to slide to the side close to the sleeve 65. Since the conical member 892 is in contact with the connecting ring 891, when the support rod 55 moves to one side, the connecting ring 891 is continuously pressed down by the conical member 892, and the positioning rod 89 continuously presses down the piston ring 83. When the downward pressure of the piston ring 83 reaches a certain level, the piston ring 83 breaks through the limit member 86 and moves rapidly. At this time, the medium in the outer cavity 812 moves rapidly into the inner cavity 811, and the piston plate 85 moves upward rapidly in the inner cavity 811 under the push of the medium, and the fire extinguishing agent enters the spray barrel 881 from the three-way pipe 87 and the hose, and is finally sprayed out from the spray hole 883.

[0077] Through the configuration of the isolation component 8, the expansion component 5, the limiter 86 and the sprayer 88, as the thermal expansion liquid continues to expand, the conical component 892 continuously applies downward pressure to the connecting ring 891, and finally exerts the downward pressure on the piston ring 83. When the downward pressure of the piston ring 83 breaks through the limiter 86, the medium in the outer cavity 812 quickly enters the inner cavity 811, and the fire extinguishing agent enters the sprayer 88 from the three-way pipe 87 and is finally sprayed out from the spray hole 883. The sprayed fire extinguishing agent isolates the air around the first connecting frame 2 to prevent the spreading fire from directly acting on the fireproof partition, which not only further extends the fireproof life of the first connecting frame 2, but also isolates the air at the connection between the composite nano-silicon glass 1 and the first connecting frame 2, thereby increasing the service life of the first fireproof gasket, and cooperates with the auxiliary sealing mechanism 6 to enhance the sealing and smoke barrier properties of the connection between the two.

[0078] Embodiment 3

[0079] Considering that when the spraying member 88 extinguishes the fire and isolates the air on the surrounding side of the first connecting frame 2, the fire source and the area with higher temperature are basically the outside of the first connecting frame 2, and the connection between the composite nano-silicon glass 1 and the first connecting frame 2 does not require too much fire extinguishing agent, further optimization is made on the basis of the above embodiment.

[0080] The connecting pipe 882 is fixedly connected to the mounting hole, and the diameter of the spray hole 883 on one side close to the first sealing gasket 41 is smaller than that on the other side.

[0081] By limiting the aperture of the spray hole 883, most of the fire extinguishing agent is sprayed on the side close to the fire source, and a small part of the fire extinguishing agent is sprayed on the connection between the composite nano-silicon glass 1 and the first connecting frame 2, thereby improving the utilization rate of the fire extinguishing agent, enhancing the air isolation effect around the first connecting frame 2, and further extending the fire protection life of the first connecting frame 2.

[0082] Embodiment 4

[0083] In order to further improve the efficiency of the isolation assembly 8 in isolating the air around the first connecting frame 2, further improvements are made on the basis of the above embodiment.

[0084] refer to Fig.13 As shown, the connecting pipe 882 is rotatably connected to the mounting hole, and a plurality of circumferentially evenly distributed guide members 884 are fixedly connected to the circumferential side of the spraying tube 881 , and the positions of the guide members 884 match the spray holes 883 .

[0085] In this embodiment, the guide member 884 is an arc-shaped guide plate, and an arc-shaped channel is formed between the arc-shaped guide plate and the spray hole 883. When the fire extinguishing agent enters the arc-shaped channel from the spray hole 883, the spraying direction of the fire extinguishing agent changes.

[0086] During use, when the fire extinguishing agent is sprayed out from the spray hole 883, the spraying direction of the fire extinguishing agent changes under the action of the guide member 884. When the fire extinguishing agent is sprayed out from multiple spray holes 883 at the same time, the spray barrel 881 starts to rotate.

[0087] Through the arrangement of the guide member 884 and the like, when the fire extinguishing agent is sprayed out from the spray hole 883, the guide member 884 guides the spraying direction of the fire extinguishing agent so that multiple streams of the sprayed fire extinguishing agent form a spiral structure, and the spray barrel 881 begins to rotate under the action of the guide member 884 and the fire extinguishing agent. Due to the action of the centrifugal force, the initial velocity of the fire extinguishing agent sprayed out from the spray hole 883 is further increased, thereby increasing the coverage area of ​​the fire extinguishing agent and improving the effective action area of ​​the isolation component 8 on the first connecting frame 2.

[0088] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
