Abstract
The utility model belongs to a cable bridge frame, in particular to a heat dissipation and flame resistant cable bridge frame, including a flute profile bridge frame main body and a cover plate of the bridge frame inserted into the main body, wherein the cover plate of the bridge frame is a mesh plate which is uniformly arranged with heat dissipation through holes on a certain part, and fire-retardant coating is coated on the inner and outer sides of the mesh plate of the cover plate of the bridge frame. The utility model has such beneficial advantages that the cable bridge frame is in particular suitable for indoor cable installation. The fireproof thermal baffles, which are added in the flame resistant cable bridge frame flute box and the inner layer of the cover plate, increases the fire resistance of the cable bridge frame; when a fire occurs, the cable bridge frame can keep a relative long operation time of the cables, to ensure the emergent needs and reduce the loss caused by the fire. The heat dissipation through holes of the cover plate of the bridge frame have good heat dispersion, and make the heat produced by the cables dissipated, ensuring the current carrying capacity of the cables. In case of a fire, because the cover plate of the bridge frame is coated with a flame retardant coating which can be thermally expanded, the coating would quickly expands and foams under the action of heat, as a result, the heat dissipation through holes are closed off to realize the effect of fire retardance and isolation, and thus to prolong the working time of the cables.
Description
Technical field
The utility model relates to the power engineering cable testing bridge, relates in particular to a kind of heat radiation fire-resisting cable crane span structure with excellent heat dispersion performance.
Background technology
Cable testing bridge is as the support body extensive use in power engineering of cable.The obturator that the fire-resisting cable crane span structure that present people generally use is pegged graft and formed by main body and cover plate, the heat that produces when working long hours owing to cable can not in time distribute, and has reduced the ampacity of cable to a great extent.Because inside does not have refractory slab, fire resistance is poor again.When breaking out of fire, it is short that cable is kept the operating time, can not guarantee emergency requirement, increases the loss that fire causes.Especially can not adapt to the requirement of fire-protection rating, those skilled in the art demand a kind of perfect heat-dissipating, fire resistance cable testing bridge up to standard urgently.
The utility model content
The utility model is in order to overcome the defective in the above-mentioned technology, thus provide a kind of fire resistance strong, help cable and produce the heat radiation fire-resisting cable crane span structure that distributing of heat reaches energy-saving and cost-reducing effect.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of heat radiation fire-resisting cable crane span structure, comprise flute profile crane span structure main body and the crane span structure cover plate that is plugged on the main body top, it is characterized in that: described crane span structure cover plate is coated with fireproof paint for the local mesh plate that is laid with the heat radiation through hole inside and outside the mesh plate of described crane span structure cover plate.
Described crane span structure main body internal layer is provided with fire-proof heat insulation board.
Described crane span structure main body outer surface scribbles the refractory coating that can meet thermal expansion.
The internal layer of described crane span structure cover plate except that mesh plate is connected with fire-proof heat insulation board, and its surface scribbles the refractory coating that can meet thermal expansion.
The beneficial effects of the utility model are: the utility model is particularly useful for house cable to be used.Fire-resisting cable crane span structure groove box and cover plate internal layer increase fire-proof heat insulation board, have improved the fire resistance of cable testing bridge, when fire takes place, can keep the work of cable long period, guarantee emergent needs, reduce the loss that fire causes.Heat radiation through hole on the crane span structure cover plate, the heat that cable is produced therefrom sheds, and prevents heat accumulation, guarantees the ampacity of cable, has good performance of heat dissipation.If breaking out of fire, because the crane span structure cover plate is coated with the refractory coating that can meet thermal expansion, coating expands rapidly, foams and the through hole shutoff of will dispelling the heat under the heat effect, plays the back-fire relief isolation effect, prolongs cable and keeps the operating time.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment technology of the present utility model is described in detail:
See accompanying drawing, a kind of heat radiation fire-resisting cable crane span structure comprises flute profile crane span structure main body 1 and the crane span structure cover plate 2 that is plugged on the main body top, described crane span structure cover plate is the local mesh plate 4 that is laid with heat radiation through hole 4-1, the heat radiation through hole can be circular hole, ellipse, stripe shape, multiple shapes such as rib type.The heat radiation through hole is according to construction requirement design perforate size, density, to satisfy good performance of heat dissipation.Mesh plate 4 can be made integral body with the crane span structure cover plate, but also split is manufactured.Be coated with fireproof paint 3 inside and outside the mesh plate of crane span structure cover plate.Crane span structure main body internal layer is provided with fire-proof heat insulation board 5.Crane span structure main body outer surface also scribbles the refractory coating 3 that can meet thermal expansion.The internal layer of described crane span structure cover plate except that mesh plate is connected with fire-proof heat insulation board 6, and its surface scribbles the refractory coating 3 that can meet thermal expansion.If breaking out of fire, the coating that can meet thermal expansion with the louvre shutoff, plays the back-fire relief effect of heat insulation after expanding rapidly, foam under the heat effect.After crane span structure main body internal layer increased fire-proof heat insulation board, fire resistance period reached 60min, doubles than original fireproof bridge frame fire resistance period, reaches national fire resistance A grade standard.Increase louvre on the crane span structure cover plate, the heat that cable is produced therefrom sheds, and guarantees the ampacity of cable.
The above only is preferred embodiment of the present utility model, is not that structure of the present utility model is done any type of restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
