Description

Technical Field

[0001] The utility model relates to the technical field of angle steel towers, in particular to an angle steel tower connecting component. Background Art

[0002] Angle steel towers are a common high-rise structure widely used in communications, electricity and other fields. Their connecting components, as an important part of the angle steel tower, are of great significance to ensuring the overall stability, bearing capacity and service life of the angle steel tower. Existing angle steel towers usually use bolts and nuts to connect themselves to the angle steel tower foundation. As the use time increases, the nuts will become loose to a certain extent, which will cause safety hazards.

[0003] The Chinese patent discloses an anti-loosening angle steel tower connection structure (authorization announcement number CN213269193U). The patented technology sets a fixing device. When assembling the angle steel tower, the connection can be made through the bolt column, and the connection is made through the screw top. The washer is fixed at the bottom end of the screw top to prevent the washer from loosening and play a shock-absorbing role. When fixed by the first nut and the second nut, the two washers are rotated in both directions to prevent the bottom nut from loosening and play a role of common limiting. The anti-rust paint can prevent the nut from rusting. The device embodies practicality; by setting a tightening device, the fixing bolt is fixed to the periphery of the bolt column, and multiple bolts are set, the purpose of which is to enhance the stability of the equipment. The first limiting groove and the second limiting groove are recessed downward and can be fixed on the screw top and hidden inside, enhancing the overall aesthetics and preventing the main body of the equipment from loosening. The third nut is used to fix the fixing bolt. The angle steel is fixed by the bolt column. The angle steel is fixed by passing through the concrete slab. The device embodies practicality;

[0004] However, it has certain disadvantages: its nut rotation structure is mainly achieved by adding washers and nuts and fixing the nut top inside the groove. Adding washers and nuts increases the stability between the bolts and nuts by increasing friction. Fixing the nut top inside the groove cannot prevent the nut from rotating. Therefore, its method of preventing the nut from loosening due to rotation due to vibration is not reliable. Utility Model Content
