Wall 3331b can be inverted T shaped steel member, and two the second strip-shaped holes run through two bottom wings of the T-type structure.
Further, the first linking arm 3331a and the second linking arm 3331b are mutually perpendicular to.Guarantee the second fire-proof plate component
313 with the installation requirements of second pipe 50.
In the embodiment of the present application, the value range of the thickness H2 of the second fire-proof plate component 313 are as follows: 28.5mm≤H2≤36mm.
Second fire-proof plate component 313 is located at the top of the first fire-proof plate component 311, and the second fire-proof plate component 313 plays most
Heat-insulated effect eventually, therefore, thickness equally should not be too thin, if the too thin purpose that can not play isolation temperature, is set greater than
In 28.5mm, above-mentioned isolation temperature purpose can be realized.Certainly, the thickness of the second fire-proof plate component 313 also should not be blocked up,
The blocked up whole assembly that will affect pipeline, therefore, the thickness of the second fire-proof plate component 313 is set smaller than equal to 36mm.
In order to facilitate transporting and assembling, the second fire-proof plate component 313 is arranged including trilaminate stack, and the fire prevention being fixedly connected
Composite plate, the second limited post 335 are convexly equipped in the fire-resistant composite panel for closing on the second active connection 333.Three layers of fire-resistant composite panel
It is fixedly connected with connector 36.
Further, each fire-resistant composite panel of the second fire-proof plate component 313 with a thickness of h2,9.5mm≤h2≤12mm.
It is more inconvenient during transport and assembly if the second fire-proof plate component 313 is set as the plate of monolith, because
This, the fire-resistant composite panel being arranged using trilaminate stack can be convenient transport and assembly.The thickness of each layer of fire-resistant composite panel is wanted
Meet 9.5mm to 12mm, so that whole thickness meets fire prevention demand.
The mode that self-tapping screw can be used in three layers of fire-resistant composite panel is assembled, and can also carry out group using other modes
Dress, within the scope of protection of this application.

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.
