[0002] Equipment noise control employs an enclosed steel frame structure, typically constructed with metal profiles surrounding a soundproof enclosure. The enclosure frame is typically constructed from cast metal profiles and connected to the frame for a secure, rigid fit. To ensure a secure connection between the columns and the frame, welding is often used on-site. However, this creates numerous fire hazards and is inconvenient for specialized requirements. This significantly complicates on-site fire prevention and management. Furthermore, deformation of the welded steel frame is difficult to correct. Therefore, a new weld-free steel frame connection structure is urgently needed to address these challenges. Utility Model Content

The outer frame connecting rod 2 is arranged on the outside of the steel frame column 1, and a plurality of inner joints 5 are fixedly provided on the outside of the steel frame column 1. The inner joints 5 are fixed to the adjacent two side walls of the steel frame column 1. One end of the outer frame connecting rod 2 is sleeved on the outside of the inner joint 5, and the adjustment rotating shaft 3 is arranged in one end of the outer frame connecting rod 2. The adjustment rotating shaft 3 passes through the outer frame connecting rod 2 and the inner joint 5. The eccentric wheel 4 is symmetrically arranged on both sides of the adjustment rotating shaft 3, and the eccentric wheel 4 is arranged on the outside of the outer frame connecting rod 2. A fixed base plate 12 is provided under the steel frame column 1, and the fixed base plate 12 is fixedly connected to the steel frame column 1. A plurality of connecting bolt holes 13 are provided at both ends of the top wall of the outer frame connecting rod 2, and a plurality of bolt through holes 14 are provided in the inner joint 5.

[0023] During specific use, determine the position of the steel frame column 1, and then connect the fixed base plate 12 below the steel frame column 1 to the ground by screws or other means, thereby installing and fixing the steel frame column 1. First install a steel frame column 1, and then put one end of the outer frame connecting rod 2 on the outside of the inner joint 5 on the outside of the steel frame column 1, so that the positioning hole 6 and the connecting hole 7 overlap. At this time, pass the adjustment rotation shaft 3 through the positioning hole 6 and the connecting hole 7, so that the connecting square shafts 9 at both ends of the adjustment rotation shaft 3 extend from the positioning hole 6.
