Description
Technical field
The utility model relates to cable fire-proof engineering field more particularly to a kind of cable duct back-fire relief band structures.
Background technique
Cable duct is the underground exterior-protected structure to lay and replace electric power or telecommunication cable facility, however cable usually because
Lead to the generation of event of fire for reasons such as excessive, short-circuit, the insulating layer damages of load, and the intensity of a fire is violent, rate of propagation is fast, causes
Very big property loss.
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 duct back-fire relief band knot is provided
Structure, cable duct back-fire relief band structure design is rationally, easy for construction, has the function of good back-fire relief, reduces when fire occurs
Property loss.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: cable duct back-fire relief band structure includes
Cable duct, back-fire relief band, bolt, bracket, cable, the first flexible organic fire prevention calking layer, fire rated partition, fireproof fibre filled layer,
Second flexible organic fire prevention calking layer, capping plate；The cable duct is rectangular configuration；Back-fire relief band is equipped in the cable duct, it should
The length of back-fire relief band is 1000-2000mm；Back-fire relief band both ends are in being bolted 3-6 on cable duct two sidewalls
Bracket is arranged, is shelved with cable on every row's bracket, in passing through the first flexible organic fire prevention calking layer on bracket between adjacent cable
It is spaced from each other；Two pieces of fire rated partitions are equipped in the middle part of the back-fire relief band, the distance between two pieces of fire rated partitions are 100-
200mm；Fireproof fibre filled layer is filled between two pieces of fire rated partitions, which sets in cable periphery
There is the second flexible organic fire prevention calking layer；Capping plate is equipped at the top of the cable duct.
Preferably, the cable surface is in being painted with cable fire-refractory coating in back-fire relief band.
Preferably, the bracket and back-fire relief are with being 100-200mm at a distance from boundary.
The beneficial effects of the utility model are: cable duct back-fire relief band structure design is rationally, and it is easy for construction, have good
Back-fire relief function reduces property loss when fire occurs.
Detailed description of the invention

9, plate 10 is covered；The cable duct 1 is rectangular configuration；It is equipped with back-fire relief band 2 in the cable duct 1, the length of the back-fire relief band 2 is
1500mm；2 both ends of back-fire relief band are in being fixed with 3 row's brackets 4, every row's bracket 4 by bolt 3 on 1 two sidewalls of cable duct
On be shelved with cable 5, be spaced from each other between adjacent cable 5 in passing through the first flexible organic fire prevention calking layer 6 on bracket 4；
Two pieces of fire rated partitions 7 are equipped in the middle part of the back-fire relief band 2, the distance between two pieces of fire rated partitions 7 are 150mm；Two pieces of resistance to fire screens
Fireproof fibre filled layer 8 is filled between plate 7, which, which is equipped with the second flexibility in 5 periphery of cable, has
Machine fire prevention calking layer 9；Capping plate 10 is equipped at the top of the cable duct 1.
When it is implemented, 5 surface of cable is in being painted with cable fire-refractory coating in back-fire relief band 2.
When it is implemented, the bracket 4 is 100mm at a distance from 2 boundary of back-fire relief band.
