Description
Technical field
The utility model relates to the back-fire relief bands of cable fire-proof engineering field more particularly to a kind of cable tunnel vent in the air
Structure.
Background technique
With the development of society, to be that we live essential for the use of electric power, the laying of cable and cable tunnel are close
It is inseparable, however cable is usually because the reasons such as excessive, short-circuit, insulating layer damage of load cause fire, and intensity of a fire ferociousness, sprawling
Speed is fast, causes huge property loss and security risk.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of cable tunnel fire in the air is provided
The back-fire relief band structure of door, the back-fire relief band structure of cable tunnel vent in the air improves the flameproof effect of cable tunnel, can be with
The isolation of fire generation area is opened, property loss when fire occurs is reduced, improves security performance.
A kind of resistance of cable tunnel vent in the air that in order to achieve the above purposes, the technical solution adopted by the utility model is:
Fiery band structure includes cable tunnel, back-fire relief band, bolt, bracket, cable, flexible organic fire prevention calking layer, fire-proof plate, back-fire relief
Packet filling wall；Back-fire relief band is equipped in the cable tunnel, which is 2000-3000mm；Back-fire relief band both ends
Bracket is arranged in being bolted 3-6 on two abutment walls of cable tunnel, distance of the bracket apart from back-fire relief with boundary is
150mm；It is shelved with cable on the bracket, the cable surface is in being coated with cable fire-refractory coating, and adjacent cable in back-fire relief band
Between be equipped with flexible organic fire prevention calking interlayer in bracket and separate；Bracket outer end on two abutment wall of cable tunnel is fixed
There is fire-proof plate；It is built in back-fire relief band both ends by water-resistant type inorganic fireproofing plugging between the fire-proof plate and cable tunnel abutment wall
There is fire retardant package to fill wall, it is 600mm which, which fills distance of the wall apart from back-fire relief with boundary,.
Preferably, the equal length of the length of the fire-proof plate and back-fire relief band.
The beneficial effects of the utility model are: the back-fire relief band structure of cable tunnel vent in the air improves cable tunnel
Flameproof effect, can by fire generation area completely cut off open, reduce fire occur when property loss, improve safety
Energy.
Detailed description of the invention
Fig. 1 is the back-fire relief band structure schematic top plan view of cable tunnel vent in the air.
Fig. 2 is the back-fire relief band structure diagrammatic cross-section of cable tunnel vent in the air.
Wherein: 1 is cable tunnel, and 2 be back-fire relief band, and 3 be bolt, and 4 be bracket, and 5 be cable, and 6 is stifled for flexible organic fire prevention
The bed of material, 7 be fire-proof plate, and 8 fill wall for fire retardant package.
Specific embodiment
In conjunction with attached drawing 1-2, the utility model is described in further detail.
As shown in Figs. 1-2, the back-fire relief band structure of a kind of cable tunnel vent in the air includes cable tunnel 1, back-fire relief band
2, bolt 3, bracket 4, cable 5, flexible organic fire prevention calking layer 6, fire-proof plate 7, fire retardant package fill wall 8；In the cable tunnel 1
Equipped with back-fire relief band 2, which is 2500mm；2 both ends of back-fire relief band pass through on two abutment walls of cable tunnel 1
Bolt 3 is fixed with 4 row's brackets 4, and distance of the bracket 4 apart from 2 boundary of back-fire relief band is 150mm；Cable is shelved on the bracket 4
5, which has between adjacent cable 5 in bracket 4 equipped with flexibility in being coated with cable fire-refractory coating in back-fire relief band 2
Machine fire prevention calking layer 6 is spaced apart；4 outer end of bracket on 1 liang of cable tunnel abutment wall is respectively and fixedly provided with fire-proof plate 7；The fire prevention
There is fire retardant package to fill wall by water-resistant type inorganic fireproofing plugging masonry in 2 both ends of back-fire relief band between 1 abutment wall of plate 7 and cable tunnel
8, it is 600mm which, which fills distance of the wall 8 apart from 2 boundary of back-fire relief band,.
When it is implemented, the equal length of the length of the fire-proof plate 7 and back-fire relief band 2.
