[0036] like Figure 1-3As shown, the utility model embodiment of a prefabricated steel structure building wall panel fire prevention node structure includes a first node structure and a second node structure, the first node structure is used to connect the flat seam type joint 1 of the enclosure wall panel 3, the second node structure is used to connect the raised seam type joint 2 of the inner partition wall panel 4, and the electromechanical opening of the inner partition wall panel 4 is provided with a fire prevention structure. The prefabricated steel structure modular building is assembled from a plurality of single module units. The enclosure wall panel 3 of the module unit is composed of a corrugated plate 5, bulk rock wool 6, and a metal rock wool insulation wall panel 7, and the inner partition wall panel 4 directly adopts a metal rock wool insulation wall panel. After the module unit is prefabricated in the factory, it is transported to the installation site for assembly, and usually two types of joint forms are formed: a flat seam type joint 1 and a raised seam type joint 2. By setting the first node structure at the flat seam type joint 1 and setting the second node structure at the raised seam type joint 2, the entire building becomes a complete whole, ensuring the overall fire prevention performance. It is usually necessary to install various electromechanical pipelines inside a building, so it is necessary to open an electromechanical installation hole on the inner partition board 4 and set a fireproof sealing structure in the electromechanical installation hole to further improve the fireproof performance.

[0037] Specifically, Figure 2 As shown, the first node structure includes a first insulation wall panel 9 and a first bending part 10. The enclosure wall panel 3 is composed of a corrugated plate 5, bulk rock wool 6 and a metal rock wool insulation wall panel 7. A steel frame column 8 is provided at the end of the enclosure wall panel 3. When assembling the enclosure wall panel 3, there is a flat seam type joint 1 between adjacent steel frame columns 8, which affects the fire resistance of the building. A first insulation wall panel 9 is arranged on the side of the steel frame column 8 close to the metal rock wool insulation wall panel 7, and both ends of the first insulation wall panel 9 are respectively fixed to the adjacent steel frame column 8 by self-tapping screws, so as to connect the steel frame columns 8 of the adjacent enclosure wall panels 3. The material of the first insulation wall panel 9 is metal rock wool, and the thickness is the same as that of the metal rock wool insulation wall panel 7 on the enclosure wall panel 3. The ends of the first insulation wall panel 9 and the metal rock wool insulation wall panel 7 are in an open state. The overflow of the rock wool inside may easily cause air pollution and pose a fire hazard. Therefore, a first bending part 10 is arranged on the side of the first insulation wall panel 9 away from the steel frame column 8. The two ends of the first bending part 10 are fixed to the metal rock wool insulation wall panel 7 on the adjacent enclosure wall panel 3 by automatic screws, so that the first bending part 10 wraps the two ends of the first insulation wall panel 9 and the ends of the metal rock wool insulation wall panel 7 on the enclosure wall panel 3 to prevent the rock wool from overflowing.

[0038] Preferably, for aesthetics, a first decorative cover 11 is provided on one side of the first bending member 10 away from the first thermal insulation wallboard 9. Both ends of the first decorative cover 11 are firmly fixed to the metal rock wool thermal insulation wallboard 7 of the adjacent enclosure wallboard 3 by using sealant.

[0039] Specifically, Figure 3As shown, the second node structure includes a second insulation wall panel 12 and a second bending piece 13. When the two inner partition panels 4 are assembled in parallel, a raised joint 2 will be formed at the open end of the inner partition panel 4, which affects the fire resistance of the building. A second insulation wall panel 12 is arranged at the raised joint 2 of the inner partition panel 4, and the second insulation wall panel 12 is flush with the open end of the inner partition panel 4. Compared with the prior art, wrapping the open end of the inner partition panel 4 saves more space. A second bending piece 13 is fixed at both ends of the second insulation wall panel 12, and the second bending piece 13 is fixed to the inner partition panel 4 with self-tapping screws. During installation, first fix the second bending piece 13 to the inner partition panel 4, and then fix the second insulation wall panel 12 to the second bending piece 13.

[0040] Preferably, a blocking bent piece 14 is provided at the open end of the inner partition board 4. The inner partition board 4 is usually made of a metal rock wool insulation wallboard. The open end of the inner partition board 4 is prone to cause internal rock wool to overflow, which is easy to pollute the air and poses a fire hazard. Therefore, a blocking bent piece 14 is fixed to the open end of the inner partition board 4 using a self-tapping screw to wrap and block the open end of the inner partition board 4.

[0041] Preferably, in order to further enhance the sealing effect, a sealant is filled in the gap between the sealing bending member 14 and the inner partition wall board 4 to form a sealing layer, which is not shown in the figure.

[0042] Preferably, a second decorative cover 15 is provided on the sealing bending piece 14. The second decorative cover 15 covers the second thermal insulation wallboard 12 and the sealing bending piece 14, and both ends of the second decorative cover 15 are fixed to the sealing bending pieces 14 on both sides by using sealant.

[0043] Specifically, Figure 4 As shown, the fireproof sealing structure includes a fire barrier sheet 17 which is arranged in the electromechanical opening connected to the wire tube 16 .

[0044] Specifically, Figure 5 As shown, the fireproof sealing structure also includes a blocking layer 20, which is arranged in the electromechanical opening connected to the water pipe 19. The blocking layer 20 is formed in the gap between the electromechanical opening and the water pipe 19 by using a sealing fireproof material.

After being prefabricated in the factory, the modular units are transported to the installation site for assembly.

[0046] When the enclosure wall panels 3 are assembled, a flat seam type joint 1 is formed between the steel frame columns 8. The first insulation wall panel 9 is installed on the side of the steel frame column 8 close to the metal rock wool insulation wall panel 7 using automatic screws, and the two ends of the first insulation wall panel 9 are connected to the adjacent steel frame column 8. Then the first bending member 10 is installed, and the two ends of the first bending member 10 are fixed to the metal rock wool insulation wall panel 7 on the adjacent enclosure wall panel 3 using self-tapping screws, and finally the first decorative cover 11 is installed. The two ends of the first decorative cover 11 are firmly fixed to the metal rock wool insulation wall panel 7 of the adjacent enclosure wall panel 3 using sealant.

[0047] When the inner partition board 4 is assembled, a convex joint 2 is formed at the end. The sealing bent piece 14 is installed at the end of the inner partition board 4 using self-tapping screws, and the gap between the sealing bent piece 14 and the inner partition board 4 is filled with sealant to form a sealing layer. The second bent piece 13 is fixed to the inner partition board 4 using self-tapping screws, and then the second insulation wall board 12 is fixed to the second bent piece 13 using self-tapping screws. Finally, the second decorative cover 15 is covered on the second insulation wall board 12 and the sealing bent piece 14, and the two ends of the second decorative cover 15 are fixed to the sealing bent pieces 14 on both sides using sealant.

[0048] According to the electromechanical drawings, electromechanical installation holes are opened on the inner partition board 4 and electrical pipelines are installed. After the wire pipe 16 is fixed to the inner partition board 4 using a pipe bracket, the socket bottom box 18 is installed. The fire barrier 17 is installed inside the socket bottom box 18, and finally the socket panel is installed.

[0049] According to the electromechanical drawings, electromechanical installation holes are opened on the inner partition board 4 and water pipes 19 are installed. The gap between the inner partition board 4 and the water pipe 19 is blocked with a sealing fireproof material to form a blocking layer 20. After the blocking is dense, valve pipe fittings 21 are installed and subsequent construction is carried out.
