Description

Technical Field

[0001] This utility model relates to the field of spherical space frame technology, and in particular to a seismic bracing device for spherical space frame steel structures. Background Technology

[0002] Earthquakes are natural disasters characterized by their suddenness and unpredictability. Therefore, the seismic resistance requirements of buildings are particularly important. Generally, building seismic resistance consists of three parts: structural seismic resistance, non-structural component seismic resistance, and seismic resistance of mechanical and electrical equipment. Currently, there is an increasing amount of mechanical and electrical equipment used in buildings. When encountering natural disasters like earthquakes, this equipment is prone to falling, leading to secondary earthquake-related disasters within the building and potentially causing safety accidents. Therefore, the supports used to hold cable trays need to have good seismic resistance.

[0003] Existing seismic bracing is mainly used in concrete structures, but its application in spherical space frame steel structure buildings has not been addressed. Furthermore, spherical space frame steel structures are difficult to fix and inconvenient to install. To address the shortcomings of existing technologies, we propose a seismic bracing device for spherical space frame steel structures. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4As shown, a seismic bracing device for a spherical space frame steel structure is disclosed. This device, through a fixed connection structure and support components, enables the spherical space frame to achieve a stable seismic resistance. The main body of the space frame is composed of four sets of steel frame supports. Each set of steel frame supports is connected by spherical connectors 1 at both ends. The spherical connectors 1 are interconnected with the upright steel frame 4 through connecting slots 2, thereby installing the four sets of steel frame supports into a spherical space frame structure. The main body of the space frame is supported by the four sets of steel frame supports. The fixed connection frame 5 is fitted onto the four sets of steel frame supports. The internal steel frame 4 is fixed using a fixed connecting frame 5. The steel frame 4 is fixed by inserting into the movable slot 11 inside the fixed connecting frame 5 and by installing a sleeve 10. The fixing bolt 12 is connected from the outside of the mounting sleeve 10 to the mounting hole 13 on the surface of the steel frame 4, thus positioning the steel frame 4. The fixed connecting frames 5 can be connected by a support frame 6 to improve the stability of the device. The two ends of the support frame 6 are connected to the connecting slot 9 and reinforced by connecting bolts 14. This improves the internal stability of the device. The installation structure of the connecting slot 9 and the mounting sleeve 10 makes the assembly of the main body of the grid frame more convenient.

[0022] Example 2, as Figures 1-4 As shown, a spherical grid steel structure seismic support device is provided. Each group of steel frame support members is equipped with a connecting column 7 on the outside to enhance the connection stability of the device. The connection between the column 7 and the steel frame 4 is completed by inserting the connecting slot 9 on the surface of the fixed connecting frame 5 into the inside of the column 7. The column 7 is assembled using the bottom support base 15 and the limiting block 16. The fixing effect of the limiting block 16 makes the column 7 more capable of supporting and fixing the steel frame support members, thereby improving the seismic performance of the device.
