Tegillum makes entire cable serving doubling by elastic component, and the side open end of cable serving is packed into protective layer, protective layer
Entire cable serving is strutted, and the bending part of cable serving is made to be softened to form an angle less than 90 degree, electricity
A cable protection chamber is formed among cable serving and the protective layer of bottom, one or more cable core is set to cable protection
It is intracavitary.
The medial surface that the cable core part is embedded in cable serving as a preferred technical solution, opens up first recessed
In slot, the cable serving other side for corresponding to cable core offers corresponding second groove, and the extension end of cable core is in cable
It is buckled into after serving doubling in the second groove of the other side, the first groove and the equal semicircular in shape shape of the second groove, first, second
Groove forms a completely circular structure after fastening, and cable core is built in the completely circular structure.
One layer of fire-proof and thermal-insulation cotton is bonded in first groove and the second groove as a preferred technical solution,
Layer.
The elastic component is an elastic memory sheet metal as a preferred technical solution, the mutual doubling of when nature,
The elastic component struts shape in an angle by the protective layer of bottom.
The bottom open end two sides of the cable serving are bonded one layer of refuge floor respectively as a preferred technical solution,
Adjacent refuge floor contacts with each other after cable serving fastening.
The refuge floor includes fire insulation serving as a preferred technical solution, and a storage is formed among fire insulation serving
Water cavity, water storage cavity inner storing water.
The hardness of the protective layer is greater than the hardness of cable serving, the outside of protective layer as a preferred technical solution,
The lateral surface of face and cable serving is coated with one layer of fireproof coating layer.
It is provided with more than one link at the top of the cable serving as a preferred technical solution, cable passes through
Link is suspended on top.
The beneficial effects of the present invention are: the present invention uses the structure of triangle, using the protection structure of base triangle, protect
Core wire and other two sides inside shield are damaged after protective layer reaches fire endurance using the fire resisting of protective layer elder generation, so that
Automatic buckling clamps cable serving under the action of the elastic member, continues the core wire inside protection, continues to bear flame calcination, increase
Add fire resistance period.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the schematic diagram of internal structure of refuge floor of the invention；
Fig. 3 is structural schematic diagram of the present invention after sag of protecting coating.
Specific embodiment
As shown in Figure 1, this composite fire cable, the triangle including cable serving 2 and a protective layer 11 splicing composition
The cable main body of shape, the base area of triangle structure is big, can be very good the calcination for first bearing bottom flame, as electricity
Protection at the top of cable uses.
2 middle of cable serving insertion, one elastic component 6 of setting, cable serving 2 make entire cable by elastic component 6
The side open end of 2 doubling of serving, cable serving 2 is packed into protective layer, and protective layer struts entire cable serving 2, and
So that the bending part of cable serving 2 is softened to form an angle less than 90 degree, the protection of cable serving 2 and bottom
Layer is intermediate to form a cable protection chamber 21, and one or more cable core 3 is set in cable protection chamber 21.
Wherein, cable core 3 is partially submerged into the first groove that the medial surface in cable serving 2 opens up, and corresponds to cable
The cable serving other side of core offers corresponding second groove 8, and the extension end of cable core 3 is buckled after cable serving doubling
Enter in the second groove 8 of the other side, the first groove and the equal semicircular in shape shape of the second groove 8, shape after the first, second groove fastens
At a completely circular structure, cable core 3 is built in the completely circular structure, is bonded with one layer in the first groove and the second groove 8
Fire-proof and thermal-insulation cotton layer 4.
Elastic component 6 is an elastic memory sheet metal, the mutual doubling of when nature, the protection which passes through bottom
Layer struts shape in an angle, elastic component doubling in nature, in this way when the protective layer of bottom bears flame calcination damage
Afterwards, protective layer breakage under the clamping force of elastic component falls off, and entire cable serving layer fastens at this time, is carried out using two face
Continue to prevent fires.
In the present embodiment, the bottom open end two sides of cable serving 2 are bonded one layer of refuge floor 7, adjacent refuge floor 7 respectively
Contacted with each other after the fastening of cable serving 2, after cable core 3 is closed by the refuge floors of two sides, can be used as inside into
One step flameproof protection, using multiple protective mode, safety is higher.
As shown in Fig. 2, refuge floor 7 includes fire insulation serving 71, a water storage cavity 72, water storage are formed among fire insulation serving
Intracavitary water storage, after cable serving fastens, the refuge floor of two sides is contacted with each other, and can prevent the flame of lower part from breaking to cable core
Bad, in addition refuge floor can be very good to transfer heat to the water in water storage cavity close to internal core wire, realize heat dissipation.
Wherein, the hardness of protective layer 11 is greater than the hardness of cable serving, the outer quilt of the lateral surface and cable of protective layer 11
The lateral surface of layer 2 is coated with one layer of fireproof coating layer 9, and the hardness of protective layer has to be larger than the hardness of cable serving, and
Elastic component can be strutted enough.
In the present embodiment, more than one link 5 is provided at the top of cable serving, cable is suspended on top by link
Portion, the present invention, particularly suitable for indoor top, are used by link as suspended cables, are reduced bottom space and are occupied.
In addition, protective layer is separated with cable serving in order to prevent, therefore it is arranged in the two sides of protective layer more than one convex
Concave point 12 is arranged in the medial surface of cable serving in point 1, and salient point 1 is buckled into compression is protected in concave point 12 and under clamping force effect
Sheath.
The beneficial effects of the present invention are: the present invention uses the structure of triangle, using the protection structure of base triangle, protect
Core wire and other two sides inside shield are damaged after protective layer reaches fire endurance using the fire resisting of protective layer elder generation, so that
Automatic buckling clamps cable serving under the action of the elastic member, continues the core wire inside protection, continues to bear flame calcination, increase
Add fire resistance period.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
