[0072] Reference Figures 1 to 4In one embodiment, in step S2, the component is a coated metal pipe 6 used for fire resistance testing.
[0073] In one embodiment, the metal pipe 6 is a stainless steel pipe or a cast iron pipe; however, the metal pipe 6 is not limited to the stainless steel pipe or cast iron pipe mentioned in this invention.
[0074] In one embodiment, the nominal diameter of the metal pipe 6 is 40mm to 450mm. The "support body 1, metal plate 3, and fixing component 4" of the present invention can achieve the fixing of large-diameter metal pipes.
[0075] In one embodiment, the metal pipe 6 is coated with a coating, which is one or more of the following: antistatic coating, anti-corrosion coating, wear-resistant coating, heat-reflective coating, high-temperature resistant coating, ultra-smooth coating, and antibacterial coating.
[0076] Reference Figures 1 to 4 In one embodiment, the metal pipe 6 includes a first pipe 61, a second pipe 62, a third pipe 63, and a tee pipe 64; before the metal pipe 6 is fixed to the support body 1, the assembly of the metal pipe 6 needs to be completed; the assembly process of the metal pipe 6 includes the following steps:

[0080] First, select a suitable type of connector 5 based on the diameter of the first pipe 61 and the diameter of the first interface of the tee pipe 64. Then, use the selected connector 5 to connect the first pipe 61 and the first interface of the tee pipe 64 together.
[0081] First, select a suitable type of connector 5 based on the diameter of the second pipe 62 and the diameter of the second interface of the tee pipe 64. Then, use the selected connector 5 to connect the second pipe 62 and the second interface of the tee pipe 64 together.
[0082] First, select a suitable connector 5 based on the diameter of the third pipe 63 and the diameter of the third interface of the tee pipe 64. Then, use the selected connector 5 to connect the third pipe 63 and the third interface of the tee pipe 64 together.
[0083] In one embodiment, the connector 5 includes one or more sealing gaskets used in pipe-to-pipe connections to prevent leakage at the pipe connections.
[0084] In one embodiment, the tee pipe 64 can be connected to pipes of different diameters through the connector 5 (such as a sealing gasket of a different model).
[0085] In one embodiment, the color and coating of the connector 5 (such as a sealing gasket) are consistent with those used on the metal pipe 6.
[0086] Reference Figure 1 In one embodiment, the first pipe 61 is used as a first vertical pipe section, the second pipe 62 is used as a second vertical pipe section, and the third pipe 63 is used as a horizontal pipe section. After the first pipe 61, the second pipe 62, the third pipe 63, and the tee 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 forms a 90° angle with the centerline of the third pipe 63.
[0087] The first joint of the tee pipe 64 is connected to the first pipe 61 via the connector 5 to achieve a seal at the joint, and the connector 5 is located at the center of the joint; the second joint of the tee pipe 64 is connected to the second pipe 62 via the connector 5 to achieve a seal at the joint, and the connector 5 is located at the center of the joint; the third joint of the tee pipe 64 is connected to the third pipe 63 via the connector 5 to achieve a seal at the joint, and the connector 5 is located at the center of the joint.

[0090] Reference Figure 1 and Figure 3 In one embodiment, the auxiliary fixing layer is a metal plate 3; the metal plate 3 is disposed on the unexposed 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 cracking.
[0091] In step S2, the first pipe 61, the second pipe 62, and the third pipe 63 are fixed to the fire-exposed side B of the first support plate of the support body 1 using the fixing component 4, and the fixing component 4 is connected to the metal plate 3 on the unexposed side of the first support plate 11.

[0093] Reference Figure 3 In one embodiment, the metal plate 3 is a T-shaped metal plate, which is disposed on the unexposed surface A of the first support plate to prevent the test component from falling off due to the first support plate 11 cracking under stress or heat. At the same time, since the T-shaped metal plate is disposed on the unexposed 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.
[0094] Reference Figures 1 to 4 In one embodiment, the third pipe 63 is mounted on the first support plate 11 and the metal plate 3 via the fixing assembly 4. Specifically, the fixing assembly 4 is used to fix the third pipe 63 in two places. During fixing, the fixing ring 41, the long nail 42, the first fastening nut 43, and the third fastening nut 45 are pre-assembled together. Then, the fixing ring 41 is fitted onto the pipe body of the third pipe 63, and the long nail 42 is positioned to pass through the first support plate 11 and the metal plate 3. Then, the second fastening nut 44 is installed. Preferably, the fixing distance between the third pipe 63 and the first support plate 11 can be adjusted by adjusting the limiting positions of the second fastening nut 44 and the third fastening nut 45. Preferably, the fixing ring 41 of the first fixing assembly 4 is 150mm away from the horizontal distance of the third interface joint of the tee pipe 64; the fixing ring 41 of the second fixing assembly 4 is 150mm away from the horizontal distance of the nearest end of the third pipe 63 (refer to...). Figure 1 For example, the horizontal distance between the fixed ring 41 and the left end of the third pipe 63 is 150mm.
[0095] Similarly, the first pipe 61 is also mounted on the first support plate 11 and the metal plate 3 by the fixing component 4; specifically, the first pipe 61 is fixed in one place using the fixing component 4; preferably, the fixing ring 41 of the fixing component 4 is 150mm vertically from the nearest end of the first pipe 61 (refer to...). Figure 1For example, the vertical distance between the fixed ring 41 and the upper end of the first pipe 61 is 150mm.
[0096] Similarly, the second pipe 62 is also mounted on the first support plate 11 and the metal plate 3 by the fixing component 4; specifically, the second pipe 62 is fixed in one place using the fixing component 4; preferably, the fixing ring 41 of the fixing component 4 is 150mm vertically from the nearest end of the second pipe 62 (refer to...). Figure 1 For example, the vertical distance between the fixed ring 41 and the lower end of the second pipe 62 is 150mm.
[0097] In one embodiment, after step S3, step S4 is further included, namely: S4, sealing the end inlets and outlets of the horizontal and vertical pipes of the component with fireproof cotton. This measure can prevent the burner flame or the flame of the external coating of the pipe from entering the pipe through the pipe port during the test.
[0098] In one embodiment, after step S4, a step S5 is further included, namely: S5, positioning the vertical pipe of the component at the apex edge of the burner 7 (refer to...). Figure 1 (e.g., placed at the corner edge of a burner viewed from above as a triangle), this arrangement allows the ignition flame to directly contact the surface of the vertical pipe.
[0099] In one embodiment, the present invention has the following advantages:
[0100] (1) The unexposed surface A of the first support plate of the present invention is provided with a metal plate 3. The fixing component 4, combined with the first support plate 11 and the metal plate 3, realizes the stable fixing of the metal pipe 6, which can effectively prevent the pipe from collapsing during the test and effectively avoid test failure.
[0101] (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.
[0102] (3) The present invention enables the tee pipe 64 to connect pipes of different diameters through the connector 5.
[0103] (4) During the test, the inlet and outlet of the vertical and horizontal pipes are sealed with fireproof cotton to prevent the burner flame or the flame of the external coating of the pipe from entering the pipe directly through the external port of the pipe.
[0104] (5) During the test, the bottom vertical pipe is placed at the top edge of the burner 7 so that the ignition flame can directly contact the surface of the bottom vertical pipe.
[0105] The present invention provides a component fire resistance performance test assembly method, which can achieve stable fixation of "coated metal pipe 6" and successfully complete the fire resistance performance test of "coated metal pipe 6".
