Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a connection structure of a solid steel frame column and a separated steel frame column. Background Art

[0002] Supertall buildings play an increasingly important role in modern urban development. They not only symbolize a city's skyline but also reflect a country's architectural expertise and economic strength. As building height increases, structural design faces greater challenges, particularly in ensuring structural safety and stability while also considering economic efficiency. Solid-web steel columns were widely adopted as the inner skeleton of megacolumns in the early stages of supertall building construction due to their excellent integrity and high load-bearing capacity. However, as building height increases, the cost of using solid-web steel columns also increases, prompting engineers to seek more economical solutions.

[0003] Through precise calculations and analysis, it was discovered that after a certain number of floors, solid steel columns can be transformed into split steel columns. This transformation is based on a deep understanding of building load distribution and a precise grasp of the properties of different types of steel. By optimizing cross-sectional shape and material usage, split steel columns can effectively reduce steel usage while ensuring structural safety, thereby saving costs. Utility Model Content

[0004] The purpose of the utility model is to provide a connection structure of a solid steel column and a separated steel column, so as to solve the problem that the prior art is difficult to ensure the overall strength of the connection position of the separated steel column and the solid steel column.

[0005] To achieve the above objectives, the specific technical solution of the connection structure of a solid steel frame column and a separate steel frame column of the present invention is as follows:

[0006] A connection structure for solid-web steel columns and detachable steel columns includes a solid-web steel column and a detachable steel column. The upper end of the solid-web steel column is connected to the detachable steel column via a connector. The connector includes a first connector connected to the longer ends of the solid-web and detachable steel columns, and a second connector connected to the shorter ends. Connecting the solid-web and detachable steel columns via the connector enhances the stability and load-bearing capacity of the overall structure. This allows the two different types of steel columns to function together, reducing steel usage while meeting safety requirements, thereby effectively saving costs.

[0007] Furthermore, the connectors are welded from a higher-grade steel than the original steel columns. Using a higher-grade steel than the original steel columns significantly improves the strength and toughness of the connection, enabling it to better withstand the loads transferred from the solid-web and split-web steel columns and reducing the risk of connection failure due to stress concentration.

[0008] Furthermore, the first connecting device and the second connecting device are both H-shaped steels that are narrow at the top and wide at the bottom. The top size of the first connecting device and the second connecting device is consistent with the size of the separated steel column, and the bottom size of the first connecting device and the second connecting device is consistent with the size of the solid steel column. By designing the first connecting device and the second connecting device as H-shaped steels that are narrow at the top and wide at the bottom, they can better adapt to the cross-sectional changes of the solid steel column and the separated steel column, achieve smooth force transmission, and reduce stress concentration. At the same time, because the top of the connector is consistent with the size of the separated steel column and the bottom is consistent with the size of the solid steel column, the connector can closely match the two different types of steel columns, improving the stability and reliability of the connection.

[0009] Furthermore, the height of the second connecting device is consistent with that of the first connecting device. Since the widths and cross-sectional areas of the two connecting members are different, when they are used as connecting members for solid-web steel frame columns and split-web steel frame columns, they need to maintain the same height to jointly bear loads from different directions.

[0010] Furthermore, the connector is made of Q420 steel. Q420 steel is a high-strength, low-alloy structural steel with high yield strength and tensile strength. Using Q420 steel as the material for the connector significantly improves its load-bearing capacity and deformation resistance.

[0011] The connection structure of the solid steel frame column and the separated steel frame column provided by the utility model has the following advantages:

[0012] Connectors are used to connect solid-web steel columns with split-web steel columns, allowing the two different types of steel columns to work together, tightly fitting them together and improving the stability and reliability of the connection. While maintaining the same strength, converting solid-web steel columns to split-web steel columns significantly reduces steel consumption compared to conventional, full-section solid-web steel columns.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] See Figure 1-5 The present invention provides a connection structure between a solid steel column and a separate steel column, for use in super-high-rise building construction. The connection structure includes a solid steel column 1 and a separate steel column 2. The solid steel column 1 is an H-shaped steel column, one large and one small, connected by a steel plate. The separate steel column 2 is two H-shaped steel columns, one large and one small, not connected by a steel plate. The solid steel column 1 and the separate steel column 2 are connected by a connector 3. The connector 3 includes a first connector 31 connected to the longer ends of the solid steel column 1 and the separate steel column 2, and a second connector 32 connected to the shorter ends. The first connector 31 and the second connector 32 are both H-shaped steel columns that are narrow at the top and wide at the bottom. The top size of the first connector 31 and the second connector 32 is consistent with the size of the separate steel column 2, and the bottom size of the first connector 31 and the second connector 32 is consistent with the size of the solid steel column 1.

[0021] When in use, the connector 3 is welded with a steel material one grade higher than the original steel column, and then welded from the inside out. A through-hole is reserved at the connection position between the connector 3 and the solid steel column 1 and the separated steel column 2, and the welding standard adopts a first-class weld. The connector 3 is fixed to the upper end of the solid steel column 1, and the bottom of the first connecting device 31 is connected to the top of the larger H-shaped steel in the solid steel column 1, and the bottom of the second connecting device 32 is connected to the top of the smaller H-shaped steel in the solid steel column 1. After fixing, the bottom of the large H-shaped steel of the separated steel column 2 is connected to the bottom of the first connecting device 31, and the bottom of the small H-shaped steel of the separated steel column 2 is connected to the bottom of the second connecting device 32. The connector 3 is completely fitted with the connection parts of the solid steel column 1 and the separated steel column 2 to ensure a safe and stable connection.

[0022] See Figure 2 The height of the second connecting device 32 is consistent with that of the first connecting device 31. Both the first connecting device 31 and the second connecting device 32 are H-shaped steels with a narrow upper end and a wide lower end. The first connecting device 31 and the second connecting device 32 are non-contact settings. The bottom and top of the first connecting device 31 are longer than the length of the second connecting device 32. It is used to fully fit with the larger H-shaped steel in the solid-web steel frame column 1 and the separated steel frame column 2. After being welded and fixed, it ensures the safety and stability of the connection position.

[0023] The connection structure of this application has the following beneficial effects:

[0024] Connectors connect solid-web steel columns to split-web steel columns, allowing the two different types of steel columns to work together, tightly fitting them together and improving the stability and reliability of the connection. While maintaining the same strength, the split-web steel column significantly reduces steel consumption compared to a conventional, full-section solid-web steel column.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
