Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wind-resistant column corner bracing nodes of portal steel frame workshops, in particular to a wind-resistant column corner bracing node structure. Background Art
[0002] Wind-resistant columns are structural components of the gable walls of single-story industrial buildings. Their primary function is to transmit the wind loads of the gable walls. These loads are transmitted to the roof system and the entire load-bearing structure through hinged connections with steel beams, and to the foundation through connections with the foundation. Currently, to ensure that the steel beams do not experience out-of-plane torsion, inclined corner braces are typically added between the wind-resistant columns and the main beams to form a triangular stability system. The corner braces are typically connected to the steel beam stiffeners. However, in large-span, large-area portal steel frame buildings, the windward surface of the wind-resistant columns is excessively large, and the wind loads are typically also extremely large. The strength of the inclined corner brace nodes is generally insufficient to withstand such high wind loads, posing a potential safety hazard. Consequently, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content
[0003] In view of the deficiencies in the prior art, the present invention provides a wind-resistant column corner bracing node structure, which solves the problems raised in the background art.
[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a wind-resistant column corner brace node structure, including an H-shaped steel wind-resistant column, the top of the H-shaped steel wind-resistant column is assembled and fixed to the H-shaped steel main beam, the top of the H-shaped steel main beam is fully welded to the purlin, the side of the H-shaped steel wind-resistant column is assembled and fixed to the vertically arranged corner brace member, and the upper side wall of the corner brace member is assembled and fixed to the H-shaped steel main beam.
[0005] The above-mentioned corner bracing member includes an H-shaped steel corner brace, and the upper side wall of the H-shaped steel corner brace is fully welded with a connecting plate, and the connecting plate is assembled and fixed to the stiffening plate on the H-shaped steel main beam through a bolt connection.
[0006] The H-shaped steel corner brace side walls and the H-shaped steel wind-resistant column side walls are assembled and fixed by bolt connectors.
[0007] The lower end of the H-shaped steel main beam is fully welded with a fixing plate, and the lower end of the fixing plate is assembled and fixed to the H-shaped steel wind-resistant column through a bolt connector.
[0008] One side of the H-shaped steel main beam is assembled and connected with an H-shaped steel secondary beam, and the lower side of the H-shaped steel secondary beam is assembled and fixed with the H-shaped steel corner brace.
[0009] Reinforcement plates are welded on the upper and lower sides of the connection positions of the above-mentioned H-shaped steel corner braces and H-shaped steel wind-resistant columns.
[0010] The utility model provides a wind-resistant column corner brace node structure. It has the following beneficial effects: the wind-resistant column corner brace node structure uses vertically arranged H-shaped steel corner braces instead of commonly used diagonal braces, which can effectively improve the strength of the upper end node of the wind-resistant column and is suitable for large-span and large-area portal steel frame factories. The H-shaped steel corner braces can be arranged in two ways: internal reinforcement and external reinforcement. Under special conditions, they can be arranged internally and externally at the same time to further improve the structural strength of the node connection position. In addition, the vertically arranged H-shaped steel corner braces are connected to the H-shaped steel wind-resistant columns and H-shaped steel main beams in an assembled manner, which can greatly improve construction efficiency.
