Technical Field

[0001] The utility model relates to the technical field of steel structure connection and discloses an H-shaped steel beam-column four-sided slope connection node. Background Art

[0002] H-shaped steel has been widely used in the field of modern steel structures due to its structural characteristics, especially in the application of beam and column components. The unique "H" shaped cross-section design of this material not only gives it excellent load-bearing capacity, but also provides good stability and rigidity.

[0003] Especially in the design and construction of sloping roof structures, H-shaped steel has shown its unique advantages. Traditional construction methods mostly use H-shaped steel beams and box columns to connect four-sided slopes. Although this method is relatively easy to construct the beam-column connection node, it will cause material waste. In addition, the four-sided slope connection method of H-shaped steel columns and H-shaped steel beams is relatively complex and takes a long time to construct, which restricts the application of this form.
