Description
Technical field
The utility model relates to a kind of building ventilation pipeline, and more particularly, it relates to and a kind ofly stops the coated system of the cable fire-proof of fire spreading.
Background technology
At present at power cable, in the laying of the multiple cable such as communication cable, often need many cables directly to concentrate in together and carry out intensive laying, or need as by embedding for electric power cable etc. with building as the arrangement such as inner, especially in the environment such as switchgear house, often many electric power cables need to be arranged in the small space of cable closely, or at the sleeve pipe of the outer coated one deck PVC material of power cable, but when breaking out of fire, because electric power cable arrangement is intensive or be embedded in the interior of articles such as building, very easily cause that electric power cable large area is on fire burns, and easily cause electric shock accidents.Therefore how cable fire-proof is effectively protected.
In prior art, Chinese Patent Application No. CN200920194587.9 open " a kind of clad type fireproof ventilation pipe structure ", it includes iron duct, suspension rod, shaped steel, body of wall, iron duct is outer by the capable lightgage steel joist of a L with tapping screw is coated baud plate, connection seam crossing between iron duct after coated is connected with seam lath by the second L-type lightgage steel joist, and the iron duct after connection is fixed on body of wall by shaped steel and suspension rod.The structure of this utility model, the iron duct after coated baud plate plate not only has good fire line, as air supply duct, effectively can reduce the loss of energy, reach energy-conservation object, and easy construction, quick, can not pernicious gas be produced when fire.Although but this structure adds fire line to a certain extent, itself still can use iron sheet, and iron sheet is inner at airduct, does institute known, and iron sheet is relative to other some fire prevention materials, and environmental requirement is higher to external world for it.In the environment that air humidity is larger, iron sheet easily gets rusty and comes off, if when being applied to the fire prevention airduct of electric power cable, there is certain potential safety hazard.
Therefore, the applicant researches and develops for some fire prevention materials and improves, and earlier application has " fire-proof magnesium composite board ", and application number is CN201210204415.1.Meanwhile, the applicant, by the utilization of this new material, applies for a kind ofly stopping the coated system of the cable fire-proof of fire spreading.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of stops the coated system of the cable fire-proof of fire spreading, when cable breaking out of fire, this system can by coated for fire in pipe box, prevent that these cables are on fire backwardly outer to be spread, thus calamity of avoiding that big fire occurs, greatly reduce damage by fire, improve fail safe.Also can protect cable after extraneous fire occurs, still can maintain its effect.
For achieving the above object, the utility model provides following technical scheme: a kind ofly stop the coated system of the cable fire-proof of fire spreading, comprise body, body is at least spliced by 2-section pipe cover, pipe box is bonded by inorganic glue by some fire-proof magnesium composite board, the junction of adjacent pipe box is provided with sealing strip, is provided with the steel tank for putting cable in pipe box.
By adopting technique scheme, during installation, cable is placed in steel tank, if during cable short circuit initiation fire, this system can by coated for fire in pipe box, prevents that these cables are on fire backwardly to be spread outward, thus calamity of avoiding that big fire occurs, greatly reduce damage by fire, improve fail safe.
The utility model is set to further: described pipe box adopts two-layer compound plate structure, and every layer of composite plate thickness is 20mm.
By adopting technique scheme, the structure of double layer composite board, add pipe box thickness, its fire endurance being extended, saving from damage under test, the fire endurance of 2 hours can be had, thus when breaking out of fire, extend its diffusion time, fully provide and find potential safety hazard and attack time, reduce loss during breaking out of fire.
The utility model is set to further: described sealing strip and pipe box adopt screw to be connected with glue.
By adopting technique scheme, connect more firm between pipe box, the connected mode of glue, is equivalent to increase a sealing ring in its junction.
The utility model is set to further: the opposite side of the corresponding steel tank of described pipe box is provided with steam vent.
By adopting technique scheme, this steam vent is less, and in routine use, cable dissipate heat, avoids temperature in pipe box too high, easily have an accident.
The utility model is set to further: described sealing strip is provided with the suspension bracket for being hung by pipe box.
By adopting technique scheme, be convenient to this system and install, the mode of installation can be dexterousr.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation that the utility model can stop the coated system of the cable fire-proof of fire spreading;
Fig. 2 is the front view that the utility model can stop the coated system of the cable fire-proof of fire spreading.
Accompanying drawing marks: 1, pipe box; 2, sealing strip; 3, steel tank; 4, suspension bracket; 5, steam vent; 6, fire-proof magnesium composite board; 7, cable.
Embodiment
Can stop that the coated system embodiment of the cable fire-proof of fire spreading is described further referring to figs. 1 through Fig. 2 to the utility model.
But the utility model can realize in various different formats, and the utility model should not be construed as and is limited to exemplary embodiment set forth herein.There is provided exemplary embodiment to contribute to more fully understanding the utility model.
As shown in Fig. 1 to 2, a kind ofly stop the coated system of the cable fire-proof of fire spreading, comprise body, body at least overlaps 1 by 2-section pipe and forms, and pipe box 1 is surrounded by some fire-proof magnesium composite board 6, and it is rectangular on cross section, adjacent two composite plates adopt M4 self-drilling connection, and spacing is about 20mm.The junction outer surface of two pipe boxes 1 is provided with sealing strip 2.Sealing strip 2 also adopts fire-proof magnesium composite board 6 to make, and its specification is that 100mm*9mm is thick.The steel tank 3 for putting cable 7 is provided with in pipe box 1.Sealing strip 2 outer surface bottom pipe box 1 is provided with the suspension bracket 4 for being hung by pipe box 1, the maximum allowable stress of this suspension bracket 4 is 10N/
.
During installation, be placed in steel tank 3 by cable 7, if during cable 7 short circuit initiation fire, this system can by coated for fire in pipe box 1, prevents that these cables 7 are on fire backwardly to be spread outward, thus calamity of avoiding that big fire occurs, greatly reduce damage by fire, improve fail safe.
