Description

Technical Field

[0001] The utility model relates to the technical field of steel columns for high-rise buildings, in particular to a cross-shaped steel column which is convenient for connecting with steel plate walls. Background Art

[0002] Steel structures are increasingly used in modern construction projects, especially in high-rise buildings and large-scale structural projects. Large concrete steel columns are increasingly being used, with cylindrical and cross-shaped steel columns being the most common. The inner and outer concrete components of cylindrical steel columns are different and unconnected, preventing them from generating a combined force. The concrete in cross-shaped steel columns, on the other hand, contacts each other, allowing for a combined force. Consequently, cross-shaped steel columns are becoming increasingly common in construction. The connection between the cross-shaped steel columns and the steel plate walls is crucial during construction. Traditional cross-shaped steel columns, when connected to steel plate walls, have the ends of the steel plate walls protrude into the concrete of the cross-shaped steel columns, leaving a certain distance between them and the cross-shaped steel columns. This creates localized stress concentration and a loose connection at the junction, impacting the overall structural stability and seismic performance. Therefore, there is an urgent need for an improved design to optimize the connection between the steel columns and the steel plate walls to enhance their overall performance. Furthermore, a stiffening plate is usually arranged on the inner side of the cross-shaped steel column. When a high reinforcement ratio is used on the outer periphery of the cross-shaped steel column and the steel bars are large and dense, ordinary stiffening plates will make pouring and vibration difficult, and the concrete will be difficult to vibrate and compact.

[0012] In a preferred solution, a plurality of stiffening plates are fixed on both sides of the non-connected steel plate wall, and the plurality of stiffening plates are intermittently arranged along the height direction of the cross-shaped web;

[0019] The utility model provides a cross-shaped steel column that is convenient for connecting steel plate walls. By adopting the above technical solution, compared with the existing technology, it has the following beneficial effects:

[0020] 1. This utility model can enhance the strength of the connection structure: by arranging T-shaped steel plates on the flanges, the component strength is effectively enhanced. Furthermore, the steel plate wall can be welded together with the cross-shaped webs to form a whole, providing a reliable connection and improving the overall load-bearing performance. Furthermore, there is ample space between the T-shaped steel plates and the cross-shaped webs, facilitating concrete vibration construction.

[0022] 3. The utility model can improve the performance of concrete vibration. A steel-concrete structure with large and dense steel bars is arranged around the periphery of the cross-shaped steel column. If conventional stiffening plates are arranged, it is difficult for the vibrating rod to reach the bottom and the concrete to be poured to the bottom, resulting in a cavity in the steel-concrete structure. By improving the shape of the stiffening plates, the inner cavity of the stiffening plates is made arc-shaped, and the flow cross-section of the inner cavity is increased, which facilitates the passage of concrete and the vibrating rod, ensures the pouring quality, makes the pouring construction more convenient, and solves the problems of difficult pouring, loose vibration and cavity. It reduces the difficulty of on-site construction and saves construction time.

[0023] 4. The utility model has a wide range of applications: This design is suitable for high-rise buildings, large steel structure projects and other structural fields that require high strength, high stability and high seismic resistance, and has broad application prospects.
