[0016] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0017] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A structural schematic diagram of a preferred embodiment of the fireproof steel-plastic door and window profile provided by the utility model; Figure 2 for Figure 1 The structural schematic diagram of the protection tube shown; Figure 3 for Figure 1The structural schematic diagram of the special-shaped steel is shown. The fireproof steel plastic door and window profile includes a protection tube 1, both sides of the protection tube 1 are connected with a connection block 7, a flame retardant groove 5 is provided inside the protection tube 1, the bottom of the protection tube 1 and the bottom of the connection block 7 are provided with a connection groove 3, a flame retardant mechanism 4 is provided inside the flame retardant groove 5, the flame retardant mechanism 4 is used to block the combustion path, and an anti-corrosion mechanism 8 is provided on the flame retardant mechanism 4, and the anti-corrosion mechanism 8 is used to reduce the corrosion of the liquid generated inside the flame retardant mechanism 4 due to the temperature difference.

The interior of the special-shaped steel 42 is a hollow through hole, and a water absorption plate 82 is inserted into the placement groove 81.

[0020] refer to Figure 1 , Figure 2 As shown in the figure, a fireproof strip installation groove 6 is opened on the top of the connecting block 7, and a fireproof rubber strip 2 is installed inside the fireproof strip installation groove 6.

[0021] It should be noted that the protective tube 1 is made of PVC material, and the protective tube 1 and the special-shaped steel 42 are made by using the steel-plastic co-extrusion process. There is no need to install a structural connection between the special-shaped steel 42 and the PVC protective tube 1, and they are directly tightly combined through the steel-plastic co-extrusion process. At the same time, the PVC material outside the special-shaped steel 42 can improve the corrosion resistance of the steel. The protective tube 1 and the connecting block 7 are an injection-molded one-piece, the special-shaped steel 42 and the connecting side plate 41 are a melt-cast one-piece, and the fireproof rubber strip 2 is clamped inside the fireproof strip mounting groove 6.
