Abstract
Based on the principle of multilayer heat insulation, the tray is mfd. with flame-resistance performance more excellent. The tray is composed of side plate made of steel sheet by cold bending and forming, bottom plate and top plate of steel ladder frame. Both of inside and outside of the tray are painted by expanding coating, the inorganic material is hung in the tray, an air passageway is in it, the air holes are placed correspondingly on the casing and inorgnaic heat-proof grough body, the connection units is hermetical. Ventilation and heat radiation can normally be realized as well as multilayer heat insulation under fire condition, so as to protect the cable.
Description
The present invention relates to a kind of common cable colony and lay the cable Fire resistant channel of usefulness.Belong to the cable fire-proof technical field, be applicable to the place of fire protection requirement, the usefulness of fireproofing of cable protection.
The cable fire accident is frequent the generation along with the raising day by day of skyscraper and industry, civil electricalization, and property loss that it causes and casualties can't be added up.Therefore caused the great attention of fire department, mandatory requirement must be taked fire-resistant measure to colony's cable laying.
From domestic and international cable fire accident illness that has not attacked the vital organs of the human body: the cable fire probability that causes from outside burning things which may cause a fire disaster is about 3/4ths of sum, and this has just shown the necessity that outside refractory protection should be arranged cable.The measure that prevents ignition of cable in existing technology divides following a few class substantially:
1, adopts fire-resisting cable, 2, adopt fire-proof cable bridge rack
Fire-resisting cable, price is higher, is not suitable for colony and lays, and can only resist fire one time, is subjected to must change behind the fire, therefore, is restricted on engineering is promoted.
Fire-proof cable bridge rack is a kind of to be not less than 1.5 millimeters thick
The shaped steel shell is a supporting mass, and the cladding thermal insulation board reaches in the housing
Heat radiation cover plate formation is set up at the top of shaped steel shell.But this veriety fire resistance is relatively poor, and the volume heaviness is installed inconvenience, and steel consumption is big, and reason such as cost an arm and a leg is limited on actual the use.
So far for this reason, yet there are no the light-duty fire-resisting cable pallet of side-vented formula that constitutes with thin steel sheet that is not more than 1.5 millimeters thick and composite heat-insulated material.
The purpose of this invention is to provide a kind of light-duty fire-resisting cable pallet that has the ventilation hole sheet metal to make side plate and the composite heat-insulated material formation that has the guard that dispel the heat, it adopts the simultaneously heat insulation way of multilayer insulation layer, good ventilation and heat condition is arranged when possessing operate as normal, reduce influence ampacity.When fire, have heat insulation function again concurrently, guarantee that cable can normally move when fire.
The object of the present invention is achieved like this: adopt the multilayer insulation layer to play the method for heat-blocking action simultaneously, reach the effect of protecting cable:
Whole pallet is divided into three layers, and one deck is the supporting shell that both sides have ventilation hole, the equal coated expanding fire-proof paint layer in the outside within it, and one deck is the composite heat shield that has the guard that dispels the heat, one deck is an air heat-insulation layer.
The fire-resisting cable pallet constitutes flute profile by shaped steel, in suspend inorganic heat dam and adding a cover, it is characterized in that: its shell constitutes with three thin-walled cold rolled shapes and ladder, and its section is
Flute profile, two side blows have ventilation hole and outlet knock down hole, the equal coated fireproof paint lacquer of both sides and bottom inside and outside wall, the flute profile inboard is provided with inorganic heat dam, shell both sides and cell body leave air duct, and suitably there are being 30 to 60 millimeters ventilation holes of diameter corresponding with the outlet knock down hole of cell body both sides apart from dashing
Cover plate is stamped on the top of shape housing, for sealed type connects, is electrically connected and adopts the copper braid over braid between adjacent cells.
The characteristics of the light-duty fire-resisting cable pallet of this ventilated type are the effects of adopting multilayer simultaneously heat insulation, reach the optimum efficiency of fire, simultaneously, pallet weight significantly alleviates, and is easy for installation, with low cost, good looking appearance helps engineering and promotes, and possesses more excellent economic benefit and social benefit.
Below in conjunction with drawings and Examples the utility model is described in detail
Fig. 1 is the present invention. structural representation
Fig. 2 is the present invention. section of structure
Fig. 3 is the present invention. the composite material heat dam structure chart that has the guard that dispels the heat
Fig. 4 is the view of heat dam shown in Figure 3
Fig. 5 is the cross section half sectional view of heat dam shown in Figure 3
Fig. 6 is a ultrathin cover plate view of the present invention
By shell (1), the composite material that has the guard that dispels the heat does not have trough (2) referring to figs. 1 through Fig. 6 the present invention, ultrathin cover plate (3), and sealed type gusset piece (4) constitutes.Shell (1) is by 1.5 millimeters punching press convex patterns (5), and dark 1.5 millimeters, and with the uniform 4 millimeters group holes of a determining deviation (6), central authorities are furnished with outlet knock down hole (7), use again
The shape steel constitutes
Shape ladder, and then seal base become
Shape.The equal coated G60-GD of the inside and outside wall of shell expanding fire-proof paint, thickness are 0.5 to 0.7 millimeter.
Heat-insulation composite material cell body (2) is composited with inorganic binder and glass fibre, thick 5 millimeters, cell body both sides axis dashes ventilation hole (10) is arranged for per 250 millimeters, its hole is looked, the product specification is 30 to 60 millimeters, shape heat radiation shutoff guard (11) is set on the ventilation hole, and corresponding with the outlet knock down hole.Air heat-insulation layer (12) is arranged between shell and the heat insulation cell body, and its spacing is 20 to 30 millimeter, shell and heat dam by
Shape steel (8), bolt and heat insulating washer (13) connect, and heat insulating washer is
Shape, bolt directly contacts with cable in order to prevent to be heated.
Cover plate (3) adopts the sheet metal of 1 millimeters thick and is pressed with the curvature of the spinal column strengthens decorative pattern, and its section is
Shape.
The usefulness of sealed type gusset piece (4) for connecting between the unit.Being electrically connected between the unit is bar shaped copper braid over braid.
For the advantage of this new construction clearly is described, the below effect of summary each parts when fire:
When the light-duty fire-resisting cable pallet of ventilated type when being subjected to fire action, flame at first acts on shell (1), this moment, the expansion coating of shell began expanded foamedly, its expansion ratio is about 50 times of former coating layer thickness.The rapid shutoff of ventilation hole of shell both sides prevents that flame from entering cell body at this moment, and the expansion coating of steel plate inboard also begins foaming and intumescing when temperature raises gradually, and shutoff extremely is arranged on the heat radiation mesh on the inorganic heat dam, and isolated heat inwardly transmits.Its conductive coefficient of heat-barrier material that is composited with inorganic binder and glass fibre is very little, and heat conduction is slower, and temperature sharply raises in the pallet so can not make within a certain period of time, thereby has guaranteed cable insulation not to be destroyed and keep normal operation.
The light-duty fire-resisting cable pallet of this ventilated type is by relevant test: temperature is no more than 150 degree in the ambient temperature 900 degree left and right sides grooves, keep and examined in 1 hour, reach designing requirement, by no matter analyzing more this pallet at fire resistance, bearing capacity, installation all obviously is better than other products, will bring more excellent economic benefit and social benefit after the enforcement.
