Technical Field
[0001] This utility model belongs to the field of steel structure technology, and in particular relates to a reinforcement component for outer ring plate and box column in steel structure buildings. Background Technology
[0002] The connection between the outer ring plate and the box column is a common structural form in steel structure buildings, especially in beam-column connections. The rigid connection between the outer ring plate and the box column can limit the rotational deformation of the beam end, making the structural node close to the "rigid connection" effect, thereby improving the overall stiffness of the structure.
[0003] The outer ring plate is usually welded to the perimeter of the box column. When the structure is under load, the outer ring plate can transfer the bending moment and shear force at the beam end to the box column, forming a rigid connection between the beam and column. After the outer ring plate is welded and fixed to the box column, if it is frequently subjected to dynamic loads, such as crane beams or large-span roofs, fatigue cracks may occur at the weld due to stress cycle. To address this, a reinforcement component for the outer ring plate and box column in steel structure buildings was designed. This component uses a combination of short-faced and long-faced perforated angle irons to reinforce the weld between the outer ring plate and the box column with tensile force. At the same time, after the outer ring plate and the box column are fixedly connected, they receive additional fixing force to reduce fatigue cracks caused by stress cycle. Utility Model Content

The cavity is threaded with positioning bolts 8. The short-faced perforated angle iron 3 and the long-faced perforated angle iron 5 are fixedly connected to the box column 1 by positioning bolts 8. The surface of the positioning bolt 8 is slidably connected with a washer 9. The washer 9 can buffer the force between the surface of the short-faced perforated angle iron 3 and the long-faced perforated angle iron 5 and the positioning bolt 8, and can prevent the surface of the short-faced perforated angle iron 3 and the long-faced perforated angle iron 5 from being worn. The surface of the long shank bolt 4 is slidably connected with a circular washer 10. The circular washer 10 is located at the top of the inner cavity of the long-faced perforated angle iron 5 and below the washer 7. The surface of the box column 1 is welded with a ring plate 11. The surfaces of the ring plate 11 and the outer ring plate 2 are both fixedly connected with a edging 12 by bolts. Example 2
[0025] Figure 1-5This invention illustrates a steel structure building reinforcement assembly for an outer ring plate and a box-shaped column, comprising: an outer ring plate 2 welded to the surface of a box-shaped column 1; a short-faced perforated angle iron 3 disposed at the top of the outer ring plate 2; a long-shank bolt 4 threadedly connected to the inner cavity of the short-faced perforated angle iron 3; a long-faced perforated angle iron 5 fixedly connected to the outer ring plate 2 by the long-shank bolt 4; the long-faced perforated angle iron 5 located at the bottom of the outer ring plate 2; a nut 6 threadedly connected to the surface of the long-shank bolt 4, the nut 6 located below the outer ring plate 2; and two washers 7 slidably connected to the surface of the long-shank bolt 4, the two washers 7 being located at the bottom of the inner cavity of the short-faced perforated angle iron 3 and the top of the inner cavity of the long-faced perforated angle iron 5, respectively. The inner cavity of the angle iron 5 is threaded with positioning bolts 8. The short-faced opening angle iron 3 and the long-faced opening angle iron 5 are fixedly connected to the box column 1 by positioning bolts 8. Limiting heads 13 are welded to opposite sides of the two edging 12. The inner cavity of the two limiting heads 13 is slidably connected with support bolts 14. The two limiting heads 13 are slidably connected with a pull rod 15 through the support bolts 14. The pull rod 15 can provide additional tension between the outer ring plate 2 and the ring plate 11, and can provide upward support for the outer ring plate 2, thereby making the connection between the outer ring plate 2 and the box column 1 more stable. A circular piece 16 is welded to the left end of the support bolt 14, and the pull rod 15 is fixedly connected to the inner cavity of the limiting head 13 through the circular piece 16.
[0026] Working principle: When using this utility model, the user uses long-shank bolts 4 to fix the short-faced perforated angle iron 3 and the long-faced perforated angle iron 5 to the upper and lower sides of the outer ring plate 2 respectively, and uses nuts 6 to fix the short-faced perforated angle iron 3 and the long-faced perforated angle iron 5 to the surface of the long-shank bolts 4. Then, the positioning bolts 8 are used to fix the short-faced perforated angle iron 3 and the long-faced perforated angle iron 5 to the surface of the box column 1. This causes the weld between the outer ring plate 2 and the box column 1 to be subjected to an inward tensile force, so that the outer ring plate 2 and the box column 1 are subjected to a fixing force other than welding. This allows the outer ring plate 2 and the box column 1 to obtain additional fixing force after being fixedly connected, thereby reducing the occurrence of fatigue cracks due to stress cycle.
[0027] In summary, the reinforcement components for the outer ring plate and box column in this steel structure building, through the combined use of short-face perforated angle iron 3 and long-face perforated angle iron 5, can strengthen the tensile force at the weld between the outer ring plate 2 and the box column 1, and provide additional fixing force between the outer ring plate 2 and the box column 1 in addition to welding. This achieves the purpose of providing additional fixing force after the outer ring plate 2 and the box column 1 are fixedly connected, thereby reducing fatigue cracks caused by stress cycles.
