Abstract
The fireproof cable bridge rack of plastic alloy includes a troughed rack and upper hood plate over the troughed rack, and features the organic heat isolating lining of non-inflammable material inside the troughed rack. In case of fire, the bridge rack can dissipate heat outwards while absorbing heat to lower temperature and retard fire so as to reach excellent fireproof effect. The present invention is superior in the smart utilization of the fireproof characteristic of organic heat isolating lining and the reasonably improved cable bridge rack first.
Description
Technical field
The present invention relates to a kind of fire-proof cable bridge rack of plastic alloy.
Background technique
Number of patent application is that to disclose " a kind of anti-corrosion, fire-retardant cable bridge frame and assembly thereof " this crane span structure be raw material with commercially available unsaturated polyester glass fiber reinforced plastics for moulding for 9610460.2 application for a patent for invention.Though advantages such as it is fire-retardant, anticorrosion, in light weight that crane span structure itself has when meeting fire trouble, but are difficult to effective flameproof protection effect is implemented in the protection of cable.
Summary of the invention
The objective of the invention is to provide a kind of fire-proof cable bridge rack of plastic alloy, and this crane span structure meets when fire is suffered from and not only can in time outwards dredge heat, and have absorbing and cooling temperature and flame retardant efficiency, and flameproof effect is good.
Fire-proof cable bridge rack of plastic alloy of the present invention comprises troffer body and the upper cover plate of being located at troffer body top, its
Be characterised in that: described troffer body inner side surface is provided with by difficulty combustion organic material and makes organic insulation blanket.
When meeting fire trouble, rise near the air temperature in the crane span structure body of naked light, and produce hot air flow, to two side flow, discharge heat along crane span structure, to avoid burning cable because of local heating; When intensity of a fire aggravation, cause the organic insulation blanket temperature in the cable bridge support body to arrive 120 ℃～200 ℃, organic insulation blanket begins softening and heat absorption, can effectively reduce the temperature of environment; Tie carbon at last, the thermal-protective material that becomes high-quality is with the protection cable.
Remarkable advantage of the present invention is, utilized dexterously organic insulation blanket temperature rise and sinter into carbon chemical change process produced helps the frpf characteristic, with the structure of reasonable improvement cable testing bridge, thereby provide a kind of safe, economic novel fire-proof cable bridge rack for the user.
Description of drawings
Fig. 1 is an embodiment of the invention organigram.
Embodiment
Fire-proof cable bridge rack of plastic alloy of the present invention comprises troffer body 1 and the upper cover plate 2 of being located at troffer body top, and it is characterized in that: (1) described upper cover plate has exhaust hole 3, and its top is provided with exhaust passage 5; (2) described troffer body inner side surface is provided with by difficulty combustion organic material and makes organic insulation blanket 4; (3) described troffer body and upper cover plate thereof are made by the metallic material that the surface scribbles fire resistant coating.
In order more to help the discharge of amount of localized heat, be equipped with inorganic heat insulation dividing plate 7 between described troffer body and the upper outlet body, with air outlet flue 8 in forming and middle air outlet flue 9 with exhaust hole 6.
For better protection cable, also be provided with inorganic insulation blanket 10 on described organic insulation blanket inner side surface.
Above-mentioned organic insulation blanket can be made by PVC material or the mixture or other organic materials that contain PVC.
Above-mentioned inorganic heat insulation dividing plate and inorganic insulation blanket can be made by gypsum board respectively.
When the crane span structure proper functioning, the temperature rise of cable is carried out cold and hot air exchange by interior air outlet flue 8, exhaust hole 6, middle air outlet flue 9, exhaust hole 3, exhaust passage 5 and is cooled off.When meeting fire trouble, rise and generation hot high pressure air-flow near the temperature in the crane span structure body of naked light, on the one hand along the middle air outlet flue 9 of crane span structure to two side flow, on the other hand when air displacement is big, exhaust hole by inorganic heat insulation dividing plate returns string to interior air outlet flue 8, along two side flow of interior air outlet flue 8, some exhaust hole 3 through upper cover plate is discharged to the two ends of exhaust passage 5 again.In case crane span structure is being burnt, the fire resistant coating of upper cover plate promptly forms foam can seal the crane span structure body automatically, invade in the crane span structure body to stop flame, and, simultaneously, the exhaust hole that leads to the exhaust passage on the upper cover plate also is in blocked state.In addition, after arriving 120 ℃～200 ℃, organic insulation blanket temperature just begins to soften, heat absorption and knot carbon, and the thermal-protective material that becomes high-quality at last is with the protection cable.Can produce a large amount of flue gases simultaneously, again this be located a large amount of heat energy and be sent to low temperature area from the high-temperature zone.The inorganic insulation blanket of being located on organic insulation blanket inner side surface 10 also provides last protection barrier for cable fire-proof with inorganic heat insulation dividing plate 7.
The present invention is novel, and is reasonable in design, safe and reliable, and market prospects are considerable.
