Description

Technical Field

[0001] This utility model relates to the field of fireproof slot box technology, specifically a composite fireproof slot box. Background Technology

[0002] Fireproof cable trays are safety devices used to prevent cable lines from catching fire due to external fires or internal faults, and to prevent the spread of fire. They feature excellent heat insulation, fire resistance, non-combustibility, non-explosiveness, water resistance, oil resistance, chemical corrosion resistance, good weather resistance, non-toxicity, high mechanical strength, light weight, high load-bearing capacity, and high safety and reliability. After the fireproof cable tray is in use, if the cables inside catch fire, they can self-extinguish due to the lack of oxygen caused by the sealed structure. External fires will also not affect the cables inside the tray due to the non-combustible nature of the tray material.

[0003] Fireproof cable trays are safe, reliable, and easy to install. They can be machined by sawing, drilling, planing, etc. They are suitable for fire-resistant separation during cable laying and are an ideal material to effectively prevent the spread of flames when cables catch fire.

The aluminum alloy fireproof cable tray includes a fireproof cable tray, a top cover, and a sealing fireproof sleeve. The top cover is slidably connected to the upper end of the fireproof cable tray, and the sealing fireproof sleeve is slidably connected to the fireproof cable tray. The fireproof cable tray is provided with partitioned slots, and the fireproof cable tray is also provided with a tightening strap and a buckle. This enables the aluminum alloy fireproof cable tray to have excellent protective performance during use, while ensuring the overall good fire resistance of the aluminum alloy fireproof cable tray. It also ensures the overall connection stability of the aluminum alloy fireproof cable tray during use, and effectively avoids the problem of other cables being affected by the spontaneous combustion or damage of a single cable, thus improving the safety and efficiency of the aluminum alloy fireproof cable tray.

[0006] 1) The traditional composite fireproof cable tray has a complex and difficult structure, and the assembly of the cable tray is not conducive to the fire protection of the internal cables. In the event of a fire, it is not possible to extinguish the fire in time and reduce the fire.

[0007] 2) Traditional composite fireproof channels are cumbersome to assemble, with complex combinations and difficult splicing during the assembly stage. Utility Model Content

The bottom of the snap-fit ​​base 18 is vertically attached to the top surface of the corresponding top cover 13.

[0035] The adjustment opening 17 and the snap-fit ​​base 18 are used to fix the corresponding top cover 13 on the cover body, and are combined into one piece.

[0036] In this embodiment, a connecting strip 19 is vertically installed in the middle of the U-shaped bracket 14.

[0037] The connecting strip 19 and U-shaped bracket 14 are used to achieve lateral transmission and binding effect at one end of the wire hole.

[0038] In this embodiment: the concave box 12 has a closed cavity installed inside the box body, the U-shaped bracket 14 has a cable transmission cavity 141 in the middle, and a clamping mechanism 2 for positioning is provided at the top center of the cable transmission cavity 141.

[0039] The clamping mechanism 2 includes a fastening screw 21 located at the top center of the U-shaped bracket 14 for limiting the position, and a sealing cap 22 located at the top center of the fastening screw 21.

[0040] The use of U-shaped bracket 14 and fastening screw 21 to tighten ensures that the inserted cable is directly transferred to the surface of U-shaped bracket 14 to achieve lateral movement.

[0041] In this embodiment: the top two sides of the sealing cover 22 are provided with side wall strips 23, the top surface of the side wall strips 23 is provided with a concave cover, and the surface of the concave cover is provided with a plurality of adjustment grooves 24 in sequence. The top center of the adjustment groove 24 is provided with a screw base 25 vertically, and the top center of the screw base 25 is provided with a connecting rod 26 vertically.

[0042] The screw base 25 is used to make the forward and backward displacement of the rod body of the connecting pole 26.

[0043] In this embodiment: a transverse frame 27 is provided at the middle of the top of the connecting pole 26, and limiting strips 28 are provided on both sides of the transverse frame 27. Assembly holes 29 are sequentially opened at the middle of the top of the limiting strips 28, and a plurality of mounting grooves 291 are sequentially provided on the surface of the assembly holes 29. The surfaces of the plurality of mounting grooves 291 are sequentially arranged on the surface of the transverse frame 27.

[0044] The structure of the mounting slot 291 is used to assemble one end of the corresponding transverse frame 27 with the external support structure, and the mounting slot 291 is used for limiting the position.

[0045] In this embodiment: A transverse mechanism 3 is installed in the middle of the top of the U-shaped bracket 14.

[0046] The U-shaped bracket 14 is used to implement the corresponding combination of limit positions in the support state, and the adjustment cavity 32 is used to facilitate heat conduction to the outside.

[0047] In practical use, the first step is: installation as a self-sealing expansion fireproof slot box;

[0048] At this time, the user uses the box state of the concave box 12 as protection for the pre-embedded wires. The wires utilize the cavity effect of the adjusting opening 17 to transfer heat and achieve the corresponding heat transfer of the wires.

[0049] At this point, the cable sheath utilizes the following materials: the outer layer is galvanized steel with a thickness of 2 mm, coated with fire-retardant steel structure paint; the inner layer is a non-metallic fire-retardant layer with a thickness of 10 mm. The fireproof cable tray must have good ventilation. When the tray overheats, the previously open ventilation holes, impregnated with special fire-retardant paint, become clogged and expand into a thick carbonized layer covering the optical cable. The small cover on the mesh automatically falls down, covering the mesh surface, causing the combustion medium to extinguish itself due to lack of oxygen. The fire resistance rating is F2, and the fire resistance duration is greater than 60 minutes.

[0051] With the support of the U-shaped bracket 14, the side wall strips 23 are used to place them back and forth.

[0052] The screw base 25 is positioned at one end against the top of the side wall strip 23 to limit the movement, and the corresponding horizontal frame 27 is fixed to the top surface by connecting the upright 26.

[0053] At this time, the limiting hole on the hole position of the limiting strip 28 and the mounting hole 29 on its surface is inserted and fixed.

[0054] According to the corresponding assembly frame 31, it is directly moved laterally and gradually installed and fixed on the surface of the adjustment cavity 32, directly fitting into the top cavity of the U-shaped bracket 14. According to the surface of the side wall strip 23, according to the threaded state of the fastening screw 21, it directly penetrates to the top two sides of the U-shaped bracket 14.

[0055] Lateral transfer is achieved according to the surface of the sidewall strip 23.
