[0038] In one embodiment, the step A1 includes: First, select a suitable type of connector 5 according to the diameter of the first pipe 61 and the diameter of the first interface of the three-way pipe 64, and then use the selected connector 5 to connect the first pipe 61 and the first interface of the three-way pipe 64 together; First, select a suitable type of connector 5 according to the diameter of the second pipe 62 and the diameter of the second interface of the three-way pipe 64, and then use the selected connector 5 to connect the second pipe 62 and the second interface of the three-way pipe 64 together; First, select a suitable type of connector 5 according to the diameter of the third pipe 63 and the diameter of the third interface of the three-way pipe 64, and then use the selected connector 5 to connect the third pipe 63 and the third interface of the three-way pipe 64 together.

[0039] In one embodiment, the connector 5 includes one or more sealing gaskets, which are used in connecting pipes to prevent leakage at the pipe connections.

[0040] In one embodiment, the three-way pipe 64 can be connected to pipes of different diameters through the interface of the connector 5 (such as selecting sealing gaskets of different models).

[0041] In one embodiment, the color and coating of the connecting member 5 (eg, sealing gasket) are consistent with those used for the metal pipe 6 .

[0042] Reference Figure 1In one embodiment, the first pipe 61 is used as the first vertical pipe section, the second pipe 62 is used as the second vertical pipe section, and the third pipe 63 is used as the horizontal pipe. After the first pipe 61, the second pipe 62, the third pipe 63, and the three-way pipe 64 are assembled, the centerline of the first pipe 61 coincides with the centerline of the second pipe 62, and the centerline of the first pipe 61 and the centerline of the third pipe 63 form a 90° angle.

[0043] The first interface seam of the three-way pipe 64 is connected to the first pipe 61 through the connecting piece 5 and the connection is sealed, and the connecting piece 5 is located at the center of the seam; the second interface seam of the three-way pipe 64 is connected to the second pipe 62 through the connecting piece 5 and the connection is sealed, and the connecting piece 5 is located at the center of the seam; the third interface seam of the three-way pipe 64 is connected to the third pipe 63 through the connecting piece 5 and the connection is sealed, and the connecting piece 5 is located at the center of the seam.

[0046] Reference Figure 1 and Figure 3 In one embodiment, the auxiliary fixing layer is a metal plate 3; the metal plate 3 is arranged on the back-fire surface A of the first support plate of the support body 1, and the metal plate 3 is used to prevent the first support plate 11 from breaking; In the S2 step, the first pipe 61, the second pipe 62 and the third pipe 63 are respectively fixed on the fire surface B side of the first support plate of the support body 1 using the fixing component 4, and ensure that the fixing component 4 is connected to the metal plate 3 on the non-fire side of the first support plate 11.

[0047] In another embodiment, the metal plate 3 may also be provided on the non-fire surface C of the second support plate for connection and fixation by the fixing assembly 4 ; the test components may also be fixed to the fire surface D side of the second support plate through the fixing assembly 4 .

[0048] Reference Figure 3In one embodiment, the metal plate 3 is a T-shaped metal plate, which is arranged on the unfired surface A of the first support plate to prevent the test component from falling off due to the first support plate 11 being subjected to force or heat cracking. At the same time, since the T-shaped metal plate is arranged on the unfired surface A of the first support plate, this arrangement effectively avoids the metal plate 3 from affecting the test results of the test component by absorbing heat and radiating energy.

[0049] Reference Figures 1 to 4 In one embodiment, the third pipe 63 is installed on the first support plate 11 and the metal plate 3 through the fixing assembly 4; specifically, the third pipe 63 is fixed using the fixing assembly 4 at two locations. When fixing, the fixing ring 41, the long spike 42, the first fastening nut 43, and the third fastening nut 45 are assembled together in advance. Then, the fixing ring 41 is put on the pipe body of the third pipe 63, and the long spike 42 is set through the first support plate 11 and the metal plate 3, and then the second fastening nut 44 is installed; wherein, preferably, by adjusting the limit positions of the second fastening nut 44 and the third fastening nut 45, the fixed distance between the third pipe 63 and the first support plate 11 can be adjusted; preferably, the fixing ring 41 of the fixing assembly 4 at the first location is 150 mm horizontally away from the third interface joint of the three-way pipe 64; the fixing ring 41 of the fixing assembly 4 at the second location is 150 mm horizontally away from the nearest end of the third pipe 63 (refer to Figure 1 , for example, the horizontal distance between the fixing ring 41 and the left end of the third pipe 63 is 150 mm).

[0050] Similarly, the first pipe 61 is also mounted on the first support plate 11 and the metal plate 3 by the fixing assembly 4. Specifically, the first pipe 61 is fixed at one location using the fixing assembly 4. Preferably, the fixing ring 41 of the fixing assembly 4 at this location is 150 mm vertically away from the nearest end of the first pipe 61 (refer to FIG. Figure 1 , such as the vertical distance between the fixing ring 41 and the upper end of the first pipe 61 is 150 mm).

[0051] Similarly, the second pipe 62 is also mounted on the first support plate 11 and the metal plate 3 by the fixing assembly 4. Specifically, the second pipe 62 is fixed at one location using the fixing assembly 4. Preferably, the fixing ring 41 of the fixing assembly 4 at this location is 150 mm vertically away from the nearest end of the second pipe 62 (refer to FIG. Figure 1 , such as the vertical distance between the fixing ring 41 and the lower end of the second pipe 62 is 150 mm).

[0052] In one embodiment, after the step S3, the step S4 is also included, namely: S4, the end inlets and outlets of the horizontal pipes and vertical pipes of the component are sealed with fireproof cotton. This measure can prevent the burner flame or the combustion flame of the outer coating of the pipe from entering the interior of the pipe through the pipe port during the test.

[0053] In one embodiment, after the step S4, the step S5 is further included, namely: S5, placing the vertical pipe of the component at the vertex edge of the burner 7 (refer to Figure 1 , such as being placed at the edge of a corner of a "triangular burner viewed from above"), this arrangement allows the pilot flame to directly contact the surface of the vertical pipe.

[0054] In one embodiment, the present invention has the following advantages: (1) The back-fire surface A of the first support plate of the present invention is provided with a metal plate 3. The fixing assembly 4 is combined with the first support plate 11 and the metal plate 3 to achieve stable fixation of the metal pipe 6, which can effectively prevent the pipe from collapsing during the test and effectively avoid test failure.

[0055] (2) The present invention can flexibly adjust the fixed distance between the pipe and the support plate through the long nail 42, the second fastening nut 44 and the third fastening nut 45, so that the fixing component 4 can fix pipes of different diameters.

[0056] (3) The present invention uses the connector 5 to enable the three-way pipe 64 to connect pipes of different diameters.

[0057] (4) During the test, the inlets and outlets at the ends of the vertical and horizontal pipes are sealed with fireproof cotton to prevent the burner flame or the combustion flame of the pipe's external coating from directly entering the pipe through the external port of the pipe during the test.

[0058] (5) During the test, the bottom vertical pipe is placed at the top edge of the burner 7 so that the pilot flame can directly contact the surface of the bottom vertical pipe.

[0059] The component fire resistance performance test assembly method of the present invention can achieve stable fixation of the "coated metal pipe 6" and successfully complete the fire resistance performance test of the "coated metal pipe 6".
