Description

Technical Field

[0001] This utility model relates to the field of tunnel fireproof board technology, and in particular to a tunnel reinforcement fireproof and explosion-proof board. Background Technology

[0002] A tunnel is a relatively enclosed tubular space. In order to prevent the reinforced concrete inside the tunnel from heating up rapidly in a fire and reducing its strength, and to avoid burning the cables and other facilities buried in the walls, fireproof boards are often installed on the top of the tunnel. Tunnel fireproof boards usually refer to the boards used to protect the concrete structure of the tunnel from fire, and are basically made of magnesium oxide board and calcium silicate board.

[0003] A search revealed that Chinese Patent Announcement No. CN219034764U discloses a special fireproof board for tunnel roofs. The board includes a flexible component that prevents the fireproof boards from warping due to mutual expansion and compression when two adjacent fireproof boards expand due to heat, through the reserved splicing gap. The guide limiting block not only increases the guidance of the insert during installation, but also limits the front and rear positions of the insert.

[0004] In actual use, the fireproof board will undergo large and prolonged deformation in places with large temperature differences between day and night or extreme temperatures. At this time, the board will be stretched or squeezed for a long time, which will greatly reduce the service life of the tough components and make them brittle. This will affect the sealing effect of the splicing gaps. To solve the above problems, a tunnel-reinforced fireproof and explosion-proof board is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tunnel-reinforced fireproof and explosion-proof panel, which aims to improve the problem in the prior art that when the panel undergoes long-term thermal expansion and contraction deformation, the lifespan of the tough components used will be greatly reduced, affecting the performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tunnel-reinforced fireproof and explosion-proof plate, comprising an arc-shaped plate body, a V-shaped groove formed on the upper surface of the arc-shaped plate body, a guide arc rod fixedly connected to the left side surface of the arc-shaped plate body, a guide arc hole formed on the right side surface of the arc-shaped plate body, a filling arc plate fixedly connected to the left side surface of the arc-shaped plate body, a rubber strip fixedly connected to the right side of the upper surface of the filling arc plate body, a groove formed at the bottom of the right side surface of the arc-shaped plate body, and a concave arc strip fixedly connected to the left inner wall surface of the groove.

[0007] As a further description of the above technical solution:

[0008] The size of the guide arc rod is adapted to the size of the guide arc hole, and the length of the guide arc rod is longer than that of the guide arc hole.

[0009] As a further description of the above technical solution:

[0010] The bending direction of the filling arc plate is the same as the bending direction of the arc plate body.

[0011] As a further description of the above technical solution:

[0012] The right surface of the rubber strip is fixedly connected to the left surface of the arc-shaped plate.

[0013] As a further description of the above technical solution:

[0014] A slot is provided on the right side of the upper surface of the filling arc plate.

[0015] As a further description of the above technical solution:

[0016] The width of the filling arc plate is greater than the width of the groove.

[0017] As a further description of the above technical solution:

[0018] The bottom end of the concave arc strip and the top end of the filling arc plate are on the same horizontal plane.

[0019] As a further description of the above technical solution:

[0020] The arc-shaped plate is composed of a base plate, a waterproof layer, an elastic layer, a sound-absorbing layer, and a fireproof layer. The base plate is located at the top, the waterproof layer is fixedly connected to the bottom surface of the base plate, the elastic layer is fixedly connected to the bottom surface of the waterproof layer, the sound-absorbing layer is fixedly connected to the bottom surface of the elastic layer, and the fireproof layer is fixedly connected to the bottom surface of the sound-absorbing layer.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the guide arc rod and guide arc hole can guide and limit the installation between the arc-shaped plates, and leave gaps between adjacent plates to avoid cracking or deformation caused by excessive thermal expansion. The gaps are sealed by the cooperation of the filling arc plate, rubber strip, groove and concave arc strip to prevent flames from affecting the upper structure through the gaps. At the same time, the concave arc strip and filling arc plate can deform relatively freely, which can also extend the service life of both.

[0023] 2. In this utility model, the elastic layer can absorb and disperse impact energy, providing a buffering effect, effectively reducing the damage of shock waves to the structure, and can absorb part of the stress through its own elastic deformation when the arc-shaped plate undergoes thermal expansion and contraction, thus extending the service life of the arc-shaped plate. The sound-absorbing layer can effectively reduce noise pollution in the tunnel. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1-2 One embodiment of this utility model is a tunnel-reinforced fireproof and explosion-proof panel, comprising an arc-shaped panel 1. A V-shaped groove 2 is formed on the upper surface of the arc-shaped panel 1. The V-shaped groove 2 can increase the local flexibility of the material, allowing the material to expand more easily along the direction of the V-shaped groove 2 when heated, thereby reducing stress concentration in other directions. This can reduce stress concentration caused by thermal expansion, thereby improving the overall stability and durability of the material. A guide arc rod 3 is fixedly connected to the left side surface of the arc-shaped panel 1, and a guide arc hole 4 is formed on the right side surface of the arc-shaped panel 1. The size of the guide arc rod 3 is adapted to the size of the guide arc hole 4, and the length of the guide arc rod 3 is longer than that of the guide arc hole 4.

[0033] When installing multiple curved panels 1, the guide arc rod 3 of the right curved panel 1 can be inserted into the guide arc hole 4 of the left curved panel 1 to quickly limit the two panels, making it convenient to complete the installation of the panels quickly. At the same time, the guide arc rod 3, which is longer than the guide arc hole 4, can keep a gap between the two panels, avoiding excessive compression between the panels when thermal expansion and contraction occurs, which could cause the panels to crack or deform and affect the service life of the fireproof and explosion-proof panels.

[0034] Reference Figures 3-4 A filling arc plate 5 is fixedly connected to the left side surface of the arc-shaped plate 1. A groove 9 is provided on the right side of the upper surface of the filling arc plate 5. The groove 9 can reduce the connection area between the filling arc plate 5 and the arc-shaped plate 1, so that the filling arc plate 5 can better deform downward when thermal expansion and contraction occur. The bending direction of the filling arc plate 5 is the same as the bending direction of the arc-shaped plate 1. When the filling arc plate 5 is heated, the distance between molecules increases, causing the material to expand along its length direction. For the arc-shaped plate, this length direction is the tangent direction of the arc. Therefore, the filling arc plate 5 will also deform and move upward more. A rubber strip 6 is fixedly connected to the right side of the upper surface of the filling arc plate 5. The right side surface of the rubber strip 6 is fixedly connected to the left side surface of the arc-shaped plate 1. The rubber strip 6 can pull the filling arc plate 5, so that when the filling arc plate 5 recovers its deformation after thermal expansion and contraction, it can quickly recover under the action of the elastic deformation force of the rubber strip 6, thereby improving the service life of the filling arc plate 5.

[0035] A groove 7 is formed at the bottom right side surface of the curved plate 1. The width of the filling curved plate 5 is greater than the width of the groove 7. When two curved plates 1 are spliced, the filling curved plate 5 will enter the interior of the groove 7 without affecting the splicing between the two curved plates 1. A concave curved strip 8 is fixedly connected to the inner left side surface of the groove 7. The bottom end of the concave curved strip 8 is at the same level as the top end of the filling curved plate 5. When the filling curved plate 5 enters the interior of the groove 7, its upper surface will fit against the bottom surface of the concave curved strip 8. At this time, the filling curved plate 5 will cooperate with the concave curved strip 8 to seal the gap left between the two plates to prevent compression. The filling enhances the overall fire resistance of the spliced ​​panels. When thermal expansion occurs due to temperature, the filling arc plate 5 and the concave arc strip 8, having sufficient deformation space, will expand and compress towards the joint, ensuring a sealing effect at the gaps. Furthermore, the free deformation also extends the service life of the filling arc plate 5 and the concave arc strip 8. During cold contraction, they will slightly separate without affecting the performance. Guide arc rods 3, guide arc holes 4, filling arc plates 5, grooves 7, and concave arc strips 8 can also be installed in the front and rear directions of the arc-shaped panel 1 to assist in the installation and use of the two spliced ​​panels.

[0036] Reference Figure 5The arc-shaped panel 1 is composed of a base plate 11, a waterproof layer 12, an elastic layer 13, a sound-absorbing layer 14, and a fireproof layer 15. The base plate 11 is located at the top and is made of high-strength aluminum alloy plate. Its main function is to provide structural support and impact resistance, and protect the layers below from mechanical damage. The waterproof layer 12 is fixedly connected to the bottom surface of the base plate 11. The waterproof layer 12 is made of polyurethane coating to prevent moisture penetration and protect the internal structure from moisture and corrosion. The presence of the waterproof layer 12 can extend the service life of the entire fireproof and explosion-proof panel, especially in humid or rainy environments. The elastic layer 13 is fixedly connected to the bottom surface of the waterproof layer 12 and is made of elastic polymer material. Its main function is to absorb and disperse impact energy and provide a buffering effect. In the event of an explosion or impact, the elastic layer 13 can effectively reduce the damage of the shock wave to the structure and enhance the overall explosion-proof performance.

[0037] The sound-absorbing layer 14 is fixedly connected to the bottom surface of the elastic layer 13. Its main function is to absorb and reduce noise and improve the acoustic environment inside the tunnel. The sound-absorbing layer 14 can effectively reduce noise pollution inside the tunnel. The fireproof layer 15 is fixedly connected to the bottom surface of the sound-absorbing layer 14. The fireproof layer 15 can be made of materials such as gypsum board, calcium silicate board, ceramic fiber board or intumescent fireproof coating. Its main function is to provide fire protection and prevent the spread of flames and high temperatures. The fireproof layer 15 can delay the spread of fire in the event of a fire, buying valuable time for personnel evacuation and fire rescue.

[0038] Working principle: When splicing fireproof and explosion-proof panels, the guide arc rods 3 of two adjacent panels can be inserted into the guide arc holes 4 of the other panel to quickly complete the initial positioning of the panels, facilitating rapid splicing and simple operation. After splicing and installation, the filler arc plate 5 will enter the groove 7 and keep in close contact with the bottom surface of the concave arc strip 8, ensuring that the gaps between the two panels are filled to prevent thermal expansion and cracking. When the temperature is high or a fire occurs, the spliced ​​panels will provide fire protection for the tunnel concrete structure. At the same time, when the arc plate 1 expands due to heat, it can deform towards the gaps to avoid excessive compression between the panels, which could cause the panels to burst or deform. The concave arc strip 8 and the filler arc plate 5 can deform relatively freely, which can also extend the service life of the filler arc plate 5 and the concave arc strip 8.

[0039] Meanwhile, when the infilled arc plate 5 and the concave arc strip 8 expand and deform due to heat, they will expand and squeeze towards the joint, further enhancing the protection effect at the gap and preventing flames from breaking through the bottom fireproof layer 15 and affecting the upper structure through the gap. At the same time, the elastic layer 13 can absorb some stress through its own elastic deformation when the board expands and contracts with heat, reducing the internal stress concentration caused by temperature changes and further improving the service life of the arc plate 1. The sound-absorbing layer 14 can improve the acoustic environment in the tunnel and effectively reduce noise pollution in the tunnel.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
