Problems solved by technology

[0004] However, there are still many problems in the existing single-track single-curtain steam-mist inorganic fire-proof rolling doors, such as the material on the fire surface is not high in temperature resistance, and only absorbs heat but does not release heat. Off-line, there is a gap between the curtain surface and the guide rail, which cannot prevent the smoke from overflowing

Embodiment 1

[0022] As shown in the figure, a single-track single-curtain steam-mist type inorganic super fire-proof rolling door is produced, including inorganic curtain surface 1, guide rail 2, seat plate 3, reel 4, fire-proof rolling door machine 5, fire-proof rolling shutter controller 6 and spray System 9: The curtain surface 1 is sequentially set as a smoke-blocking decorative cloth 11, a fireproof cloth 12, a fireproof blanket 13 and a reflective cloth 14 from the fire-receiving surface to the back-fire surface; the curtain surface 1 is connected by multiple splints 15 and multiple bolts 16 fixed; the curtain surface 1 is longitudinally provided with a plurality of steel wire ropes 17; the guide rail 2 is made of cold-rolled steel plate, and the inside of the fire-receiving side is provided with a smoke-proof device 7; the seat plate 3 is made of angle steel; the reel 4 is made of fireproof The rolling door machine 5 is driven, and the sprinkler system 9 includes a water spray pipe 9...

Embodiment 2

[0024] Further, on the basis of Example 1, the laminated structure of the curtain surface 1 is arranged sequentially from the fire-receiving surface to the back-fire surface as a smoke-blocking decorative cloth 11 , a reflective cloth 14 , a fireproof cloth 12 , a fireproof blanket 13 and a reflective cloth 15 . In this way, a single-track single-curtain steam-mist type inorganic super fire-resistant rolling door can be made that can better reflect heat and slow down temperature rise.

Embodiment 3

[0026] Further, the thickness of the smoke-blocking decorative cloth 11 that constitutes the curtain surface 1 in Embodiment 1 and Embodiment 2 is made into 0.4mm, the thickness of the fireproof cloth 12 is made into 2mm, the thickness of the fireproof blanket 13 is made into 9.4mm, and the thickness of the reflective cloth 14 is made into Become 0.2mm; The clamping plate 15 that connects fixed curtain surface 1 adopts galvanized steel plate, and the spacing of clamping plate 15 is made into 450mm, and the spacing of bolt 16 is made into 450mm; The spacing of steel wire rope 17 in curtain surface 1 is made into 450mm; Water spray pipe 91 The distance apart from the backfired side of the curtain is set to 200mm, and the aperture of the spray hole 92 on the spray pipe 91 is made as 2mm, and the hole pitch is made as 50mm. In this way, a single-track single-curtain steam-mist type inorganic super fire-proof rolling door with practical application value has been made.

Abstract

A single-track single-shutter steam fog type inorganic special-grade fireproof rolling shutter door comprises an inorganic shutter surface, a guide rail, a seat plate, a reel, a fireproof door roller, a fireproof rolling shutter controller and a spraying system. The single-track single-shutter steam fog type inorganic special-grade fireproof rolling shutter door has the benefits as follows: the shutter surface is formed by stacking multiple layers of materials with corresponding functions, can reflect heat, and effectively reduces temperature rise; the shutter surface is hung by steel wire ropes, so that the service life can be prolonged, and the defects that common sewing threads are not resistant to high temperature, and easy to break when being encountered with fire can be avoided; a layer of reflective cloth is additionally arranged inside the shutter surface, so that heat entering the shutter surface can be effectively reduced; the spraying system is arranged on the side unexposed to fire, so that the temperature rise can be effectively reduced; a smoke-proof device is additionally arranged inside the guide rail, so that sealing strips can expand after being heated to extrude and seal gaps between the shutter surface and the guide rail; an expansion spraying device is additionally arranged inside the guide rail, so that water inside a lug groove cavity of the guide rail can expand after being heated to extrude and puncture the bottom wall with a small hole to be jetted towards the shutter surface, therefore, the temperature of the shutter surface is reduced, and the fireproof time is effectively prolonged.

Description

technical field [0001] The invention relates to a fire-proof rolling door, in particular to a monorail single-curtain steam-mist type inorganic super fire-proof rolling door. Background technique [0002] Compared with ordinary rolling doors, fire-resistant rolling doors have higher requirements on fire protection. They must meet the requirements of national standards and regulations for TF3 fire protection ratings. The temperature rise of the back-fired surface is used as the judgment condition, and the fire-resistant rolling shutters with a fire resistance limit of not less than 3H are special grades. Fireproof Shutter. [0003] In order to meet the requirements of super fire protection, various products have been produced. The more popular ones are aerosol fire shutter door, evaporation fire shutter door, monorail single curtain steam mist inorganic fire shutter door, water service type fire shutter door, etc. These shutter doors have their own characteristics. , general...
