[0002] Fireproof tunnel panels are a special building material, mainly used for fire isolation and protection inside tunnels. They have excellent fireproof properties and can effectively prevent the spread of fire and ensure safety inside tunnels.

[0003] Although the existing fireproof tunnel panels can prevent fires during use, it is not convenient to limit the panels during installation. A lot of effort is required to align the panels when fixing them. At the same time, the fireproof effect of the panels is not good. When isolating the flames, damage may occur, causing the fire to spread rapidly, thereby reducing the ease of installation and fireproof effect of the traditional fireproof tunnel panels. Thus, a fireproof tunnel panel is introduced. Utility Model Content

[0012] As a preferred technical solution of the utility model: the number of the expansion bolts and the thread grooves are both several, and the several expansion bolts and the thread grooves are respectively located on the inner wall of the fireproof panel.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When installing the fireproof board, the fireproof tunnel board aligns the clamping block at the bottom of the backing board strip with the clamping groove at the top of the fireproof board, and the staff presses it. The clamping block will retract after being pressed, so that the clamping block can be easily moved to the inner wall of the clamping groove for clamping.

Then, the staff needs to apply appropriate pressure to make the clamping block 5 shrink after being compressed, so that it can be smoothly embedded in the inner wall of the clamping groove 11 to achieve clamping and fixation. Next, the staff will install the expansion bolt 3 to ensure that the expansion bolt 3 is tightly connected to the security fireproof board 1 and the backing strip 2 respectively through a threaded connection, so as to achieve a firm fixation of the security fireproof board 1 and the backing strip 2.

[0026] In the above structure, the anti-corrosion measures of the fireproof board 1 are taken by the anti-corrosion layer 9 to ensure that the fireproof board 1 will not be corroded during long-term storage. In addition, the metal mesh 8 is used to absorb the heat generated by the flame, and then transfer the heat to the thermal insulation layer 7, which effectively isolates the heat. Finally, the adhesive layer 6 is used to fix the positions of the thermal insulation layer 7, the metal mesh 8 and the anti-corrosion layer 9 to ensure that the three will not separate during the placement process, thereby ensuring the stability of the fireproof effect.

[0027] In a preferred embodiment, the clamping block 5 is adapted to the inner wall of the clamping groove 11 , and the clamping block 5 is clamped to the inner wall of the clamping groove 11 .

[0028] In the above structure, the clamping block 5 contracts after being subjected to pressure, so that the clamping block 5 can enter the inner wall of the clamping groove 11 more smoothly, and is also clamped and fixed with the inner wall of the clamping groove 11 at the same time.

[0029] In a preferred embodiment: a threaded groove 4 is provided at the bottom of the backing strip 2 , and the fireproof panel 1 is fixedly assembled with the backing strip 2 by means of expansion bolts 3 and the threaded groove 4 .

[0030] In the above structure, the fireproof board 1 and the backing strip 2 are fixed by the expansion bolts 3 to prevent the boards from falling during placement.

[0031] In a preferred embodiment, the clamping block 5 is made of rubber, and the single long side of the fireproof board 1 is an 85-degree slope.

[0032] In the above structure, the snap-in block 5 is made of rubber, so that the snap-in block 5 will shrink and rebound after being subjected to pressure. At the same time, the single-side angle of the security fireproof board 1 is eighty-five degrees, so that the gap between the two groups of security fireproof boards 1 when installed will not be greater than three millimeters, making the multiple security fireproof boards 1 more tightly connected.

[0033] In a preferred embodiment, the expansion bolt 3 is made of stainless steel, and the heat insulation layer 7 is located between the adhesive layer 6 and the metal mesh 8 .

[0034] In the above structure, the device can be better fixed by the expansion bolts 3 after installation.

[0035] In a preferred embodiment: the adhesive layer 6, the thermal insulation layer 7, the metal mesh 8 and the anti-corrosion layer 9 are all adapted to the inner wall of the preservation fireproof board 1, and the adhesive layer 6, the thermal insulation layer 7, the metal mesh 8 and the anti-corrosion layer 9 are all tightly fitted to the inner wall of the preservation fireproof board 1.

[0036] In the above structure, the adhesive layer 6, the heat insulating layer 7, the metal mesh 8 and the anti-corrosion layer 9 are just matched with the inner wall of the fireproof board 1 during assembly, and the inner wall of the fireproof board 1 is in a sealed state during assembly.

[0037] In a preferred embodiment, there are a plurality of expansion bolts 3 and a plurality of thread grooves 4 , and the plurality of expansion bolts 3 and the thread grooves 4 are respectively located on the inner wall of the fireproof panel 1 .

[0038] In the above structure, the fireproof panel 1 is fixed by fixing the fireproof panel 1 by making different numbers of expansion bolts 3 installed during installation due to different widths of the fireproof panel 1 .

[0039] Working principle: During the installation process, first align the snap-in block 5 at the bottom of the backing strip 2 with the snap-in groove 11 at the top of the fireproof board 1, and then apply pressure by the staff. When the snap-in block 5 is under pressure, it retracts to facilitate smooth snap-in to the inner wall of the snap-in groove 11, thereby achieving a preliminary connection between the two. Next, the staff installs the expansion bolt 3, which is threadedly connected to the fireproof board 1 and the backing strip 2, respectively, so as to firmly fix the fireproof board 1 and the backing strip 2. The single-side angle of the fireproof board 1 is designed to be 85 degrees. Ensure that when two sets of security fireproof panels 1 are installed, the spacing between them will not be greater than three millimeters to ensure that multiple security fireproof panels 1 have higher tightness when connected. The security fireproof panels 1 are treated with anti-corrosion through the anti-corrosion layer 9 to ensure that they will not corrode under long-term storage. At the same time, the metal mesh 8 has a flame absorption function, which can absorb heat and transfer it to the insulation layer 7, and the insulation layer 7 isolates the heat. In order to ensure the stability of the insulation layer 7, the metal mesh 8 and the anti-corrosion layer 9 during the placement process, we fix them with an adhesive layer 6 to prevent them from detaching and affecting the overall fireproof effect.
