[0016] Compared with the prior art, the beneficial effects of the present invention are: the energy-saving and heat-insulating safety steel structure exterior wall can improve the sealing of the joints between multiple polystyrene boards, prevent heat from escaping from the joint gaps, so that the entire steel structure exterior wall can reduce the indoor heat dissipation when used in winter, and can block the outdoor heat from entering the room when used in summer, thereby achieving the effect of energy saving, heat preservation and heat insulation. The specific contents are as follows: (1) When multiple polystyrene boards are spliced ​​together through the splicing connector, the control airbag is squeezed by the second splicing block, so that the air in the control airbag enters the sealing airbag through the connecting pipe, thereby causing the volume of the sealing airbag to expand and closely fit with the outer side of the first splicing block, thereby improving the sealing of the splicing between the multiple polystyrene boards and preventing heat from escaping from the splicing gap to the outside. As a result, the entire steel structure exterior wall can reduce the dissipation of indoor heat when used in winter, and can block the outdoor heat from entering the room when used in summer, thereby achieving energy-saving, heat preservation and heat insulation effects; Through the coordinated arrangement of the hollow horizontal control panel and the hollow vertical control panel, multiple first steel sections and second steel sections can be separated to prevent heat from forming a thermal bridge through the first steel section and the second steel section and conducting heat outward, thereby improving the overall thermal insulation effect of the steel structure exterior wall. By installing a rock wool layer on the outside of the first steel section and the second steel section, the thermal bridge effect between the first steel section and the second steel section can be further reduced.

[0017] (2) By symmetrically arranging two rows of hollow horizontal control panels and hollow vertical control panels, the interior of the entire steel structure exterior wall is hollow, so that an air layer can be formed in the hollow area. In this way, the air layer can play a buffering and heat-insulating role, preventing indoor heat from dissipating to the outside in winter and blocking outdoor heat from entering the room in summer.

[0018] (3) Through the coordination of vertical reinforcing bars, horizontal supporting steel bars in an "I"-shaped structure, and auxiliary supporting steel bars in an inverted "V"-shaped structure, the horizontal stability of the installation between the two rows of hollow horizontal control panels and the hollow vertical control panels can be improved, thereby improving the safety performance of the entire steel structure exterior wall during use.

[0019] (4) Apply sound insulation paint between two rows of metal meshes. The combination of metal meshes and sound insulation paint increases the number of pores in the sound insulation paint, which in turn enables these pores to reflect and absorb sound multiple times, thereby achieving a better sound insulation effect. The entire steel structure exterior wall is well used in steel structure buildings close to traffic roads to prevent external traffic noise from entering the interior.
