Plate 3113 is fixedly connected with connector 36.
The installation of the fire prevention component 30 is convenient in the setting of the first fixed fire-proof plate 3113, provides just for site operation
Benefit.
In the embodiment of the present application, the value range of the thickness H1 of the first fire-proof plate component 311 are as follows: 28.5mm≤H1≤36mm.
First fire-proof plate component 311 plays the role of preliminary fireproof, and therefore, thickness should not be too thin, if too thin can not play
Fireproof purpose is set greater than and above-mentioned fire prevention purpose can be realized equal to 28.5mm.Certainly, the first fire-proof plate component 311
Thickness also should not be blocked up, therefore the blocked up whole assembly that will affect pipeline, the thickness of the first fire-proof plate component 311 is set
It is set to and is less than or equal to 36mm.
With continued reference to Fig. 4, for convenience transport and assembly of the first fire-proof plate 3111, the first fire-proof plate 3111 includes three layers
The fire-resistant composite panel 3111a being stacked, the first fixed fire-proof plate 3113 include the fixation fire-resistant composite panel of trilaminate stack setting
3113a, three layers of fire-resistant composite panel 3111a and three layers of fixed fire-resistant composite panel 3113a are fixedly connected with connector 36, and a fire prevention is multiple
The fixed fire-resistant composite panel 3113a of plywood 3111a docking one.The mode that self-tapping screw can be used in three layers of fire-resistant composite panel carries out group
Dress can also be assembled, within the scope of protection of this application using other modes.
Further, the transport and assembly of the first fire-proof plate component 311 for convenience, each of the first fire-proof plate 3111 prevent
Fiery composite plate 3111a with a thickness of h1,9.5mm≤h1≤12mm, fixed fire-resistant composite panel 3133a and the fire-resistant composite panel
The consistency of thickness of 3131a.
It, can be using following setting in order to realize better flameproof effect: in three layers of fire-resistant composite panel, steel from the bottom to top
The thickness of plate is gradually reduced, and the thickness of three's entirety still will meet 28.5mm≤H1≤36mm.Because of underlying steel plate
Thickness it is sufficiently thick, when generating the biggish intensity of a fire, underlying steel plate plays resisting for first layer, will not be excessive because of the intensity of a fire
And generate deformation.
The fire-resistant composite panel is a kind of clad steel plate, and internal layer is the cement core layer of adding of fiber, and outside is 0.5mm thick
There is hole galvanized steel plain sheet.
In the embodiment of the application, thermal insulator 312 is asbestos.Asbestos are also known as " asbestos fibre ", for that can split into richness
The general name of flexible filametntary certain silicate minerals.Chemical formula: 3MgO2SiO2·2H2O, in threadiness, green-yellow or
White splits into white when wadding, silky luster, fiber high resilience, and asbestos have acidproof, alkaline-resisting and heat resistance, and is heat
With the non-conductor of electricity.Therefore, the thermal insulator 312 of the application uses asbestos material, can preferable heat-insulating, fire-preventing.
Further, the value range of the thickness H3 of thermal insulator 312 are as follows: 120mm≤H3≤150mm.Likewise, thermal insulator
312 thickness should not be too thin, if the too thin purpose that can not play isolation temperature, is set greater than equal to 120mm, can be realized above-mentioned
Isolation temperature purpose.The thickness of certain thermal insulator 312 also should not be blocked up, the blocked up whole assembly that will affect pipeline, therefore,
The thickness of thermal insulator 312 is set smaller than equal to 150mm.
Combined with Figure 1 and Figure 2, in the embodiment of the application, one end away from fire resistant flexible band 35 of thermal insulator 312 is set
There is auxiliary fire guard 34, one end of the auxiliary fire guard 34 is connect with thermal insulator 312, and the other end is connect with first pipe 40.
That is, thermal insulator 312 is during installation, both ends do not connect directly with the end of first pipe 40 and second pipe 50
It connecing, 312 one end of thermal insulator is connected by fire resistant flexible band 35 in second pipe 50, and another section is connected by auxiliary fire guard 34,
The auxiliary fire guard 34 is similar with the effect of fire resistant flexible band 35, stops to the transmitting of heat.
In the embodiment of the application, first pipe 40 and the adjacent end face of second pipe 50 are convexly equipped with the first company respectively
Section 41 and the second linkage section 51 are connect, water blocking tape component 10 connects first linkage section 41 and the second linkage section 51, water blocking tape component
10, the end face of the first linkage section 41, the second linkage section 51, the end face of first pipe 40 and second pipe 50 and the first fire prevention
Board group part 311, which encloses, to be set to form fire protection space, and the second fire-proof plate component 313 and thermal insulator 312 are located in the fire protection space.
The fire protection space of such setting, not only can fire prevention component 30 and water blocking tape component 10 convenient for assembly, but also make whole
It is compact-sized.
Further, thermal insulator 312 is installed on the first fire-proof plate component 311 towards the surface of the second fire-proof plate component 313.
When component 30 is prevented fires in assembly, first the first fire-proof plate component 311 is assembled, then assembles thermal insulator 312 in the first fire prevention
The surface of board group part 311, then in assembly fire resistant flexible band 35, finally again assembling the second fire-proof plate component 313 can be complete
The whole assembly from entirety.The upper and lower surface of thermal insulator 312 can be connected to the upper surface and of the first fire-proof plate component 311 respectively
The lower surface of two fire-proof plate components 313 is only installed at the it is of course also possible to use similar shown in diagram with the application
The upper surface of one fire-proof plate component 311.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
