Dress, within the scope of protection of this application.
In the embodiment of the application, thermal insulation barriers 312 are 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：3MgO·2SiO2·2H2O, 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 insulation barriers 312 of the application use asbestos material, can preferable heat-insulating, fire-preventing.
Further, the value range of the thickness H3 of thermal insulation barriers 312 is：120mm≤H3≤150mm.
Likewise, 312 thickness of thermal insulation barriers should not be too thin, if the too thin purpose that can not play isolation temperature, is set greater than
Equal to 120mm, you can realize above-mentioned isolation temperature purpose.The thickness of certain thermal insulation barriers 312 also should not be blocked up, blocked up meeting shadow
The whole assembly in speaking pipe road 50, therefore, the thickness of thermal insulation barriers 312 is set smaller than equal to 150mm.
Combined with Figure 1 and Figure 2, in the embodiment of the application, thermal insulation barriers 312 are set away from one end of fire resistant flexible band 35
There are auxiliary fire guard 34, one end of the auxiliary fire guard 34 to be connect with thermal insulation barriers 312, the other end is connect with first pipe 40.
That is, thermal insulation barriers 312 are when mounted, both ends do not connect directly with the end of first pipe 40 and second pipe 50
It connecing, 312 one end of thermal insulation barriers 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 transmission 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 insulation barriers 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 insulation barriers 312 are 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 insulation barriers 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 insulation barriers 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, it is of course also possible to use it is similar illustrate with the application in it is shown, be only installed at the
The upper surface of one fire-proof plate component 311.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
It is every under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes
It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
