Description
Technical field
The utility model relates to power transmission and distribution equipment technical field, particularly relates to a kind of fireproof bridge frame structure.
Background technology
Crane span structure is for field of power distribution for supporting and lay the device of fixed cable, when laying all kinds of power cable, the illumination overhead line such as distribution, control cables, all needs to use fireproof bridge frame and prevents the accident of unexpected initiation fire from occurring. Now metal fireproof bridge frame in the art is typically used in metal crane span structure appearance coating flame retardant paint, utilizes the flame retardant paint of coating to play fp effect, and the flame retardant paint structure of fireproof bridge frame is comparatively single, and fp effect is not fine. Need to be improved by existing cable testing bridge, to improve the fire resistance of fireproof bridge frame, and ensure fireproof bridge frame good integral strength, it is possible to meet fire-protection rating and require that higher occasion uses.
Summary of the invention
For overcoming the deficiencies in the prior art, the fireproof bridge frame structure that the utility model provides a kind of bulk strength height, fire resistance is good.
The utility model is reach the technical scheme that above-mentioned technical purpose adopts to be: a kind of fireproof bridge frame structure, comprise cable channel and the cover sheet of metal, described cable channel comprises base plate and two side plates, the junction of the base plate of described cable channel and two side plates is respectively provided with the groove of an outwardly convex, described groove is provided with the through hole of evenly setting, the inner side of the base plate of described cable channel and two side plates is provided with fireproof coating layer and fire proof heat-insulation layer, two side plate edges of described cable channel are provided with folding flange, described cover sheet is provided with the card groove of the outwardly convex corresponding with described flange, the inner side of described cover sheet is provided with fireproof coating basic unit, it is provided with fire-proof and thermal-insulation dividing plate between two card grooves inside described cover sheet, the outer side of described cable channel and cover sheet is respectively equipped with fireproof coating basic unit and corrosion protection coating.
The base plate of described cable channel is provided with the stamped female convex tendon strengthening intensity.
Two side plates of described cable channel are provided with locking open holes.
The beneficial effects of the utility model are: after adopting said structure, by arranging the groove of outwardly convex in the base plate of cable channel, and the inner side of cable channel is provided with fireproof coating layer and fire proof heat-insulation layer, cover sheet arranges the card groove of the outwardly convex corresponding with the flange on cable channel side plate, and between two card grooves inside cover sheet, fire-proof and thermal-insulation dividing plate is set, fireproof coating basic unit and corrosion protection coating on the outer side of cable channel and cover sheet, make cable channel and the cover sheet bulk strength height of formation crane span structure, distortion it is not easy when installing and using, fireproof coating basic unit and fire proof heat-insulation layer unitized construction guarantee that crane span structure fire resistance is good, the fire-protection rating height of crane span structure.
