Description

Technical Field

[0001] This utility model relates to the field of connection structure technology, specifically a dome steel structure connection structure. Background Technology

[0002] A steel dome is a type of dome-shaped building that uses a steel structure as its main supporting structure. It consists of a steel frame and a glass covering. The steel frame typically uses lightweight steel components, which are welded and connected to form the overall framework of the dome. The glass is fixed to the steel frame using a special method, forming the covering layer of the entire dome. Steel domes are widely used in various large public buildings, such as commercial centers, exhibition halls, stadiums, and airports. Their unique structure and design make these buildings visually more magnificent and spectacular, while also providing excellent lighting and views. Due to the varying curvature of the dome, the connection method between the dome and the supporting steel columns also varies. Traditionally, welding is the most common method. However, since the dome is composed of multiple steel frames, it is necessary to change positions to replace them. Working at heights carries a high risk of injury. To facilitate the connection and installation of the dome's steel structure, a new dome steel structure connection structure is proposed.

[0004] Although it solves the problem that the existing dome support connection structure cannot simultaneously connect the top and bottom of multiple dome supports, and cannot automatically lock at the bottom while connecting;

[0005] However, the existing connection structure does not solve the problems of the inconvenience of sequentially inserting steel frames to form a dome and the difficulty of quickly disassembling and maintaining the support frame during use. It also does not provide stable support for the dome and avoid the situation where construction workers frequently walk around when working at heights, thus affecting the safety and convenience of dome connection and installation.

The connector 7 is suspended in mid-air by hoisting. Then turn on the drive motor 2, which drives the gear 3 to rotate. Under the mutual meshing of the gear 3 and the gear ring 4, and the sliding cooperation between the movable ring 5 and the bearing ring frame 1, the gear 3 drives the movable ring 5 to rotate through the gear ring 4. The movable ring 5 drives the mounting seat 8, the limit block 10, and the support. The frame 9 and the support seat 11 are rotated to the installation position in sequence. Then, the steel frame 6 is taken out in sequence, the plug 12 is inserted into the inside of the connector 7, and the bottom is inserted into the support seat 11. With the cooperation of multiple sets of steel frames 6 and connector 7, and with the cooperation of steel frames 6 and support seat 11, multiple sets of steel frames 6 are assembled into a dome, thereby completing the installation and connection of the dome. This realizes the convenient sequential insertion of steel frames to form a dome, avoids the situation where construction personnel have to walk around frequently when working at height, and improves the safety of dome connection and installation.

The support frame 9 provides support for it, so that the adjusting arm 15 rotates and contacts the steel frame 6. The adjusting arm 15 provides support for the steel frame 6, thereby increasing the stability of the dome. After that, the locking pins 18 are reinserted and tightened to fix the sliding rod 17 and the sleeve 13. If maintenance is required for a certain set of support frames 9, simply pull the support frame 9 upward.

After multiple sets of steel frames 6 are assembled into a dome, the locking pins 18 are unscrewed, and the sliding rod 17 is moved. The sliding rod 17 slides inside the sleeve 13 and drives the sleeve 13 to rotate. The sliding rod 17 drives the adjusting arm 15 to rotate around the movable shaft 14 through the hinge shaft 16. The support frame 9 provides support for it, so that the adjusting arm 15 rotates and contacts the steel frame 6. The adjusting arm 15 provides support for the steel frame 6, thereby increasing the stability of the dome. After that, the locking pins 18 are reinserted and tightened to fix the sliding rod 17 and the sleeve 13. If a set of support frames 9 needs to be maintained, simply pull the support frame 9 upward. The support frame 9 will drive the limiting block 10 to be pulled out from inside the mounting base 8, so that the support frame 9 is separated from the mounting base 8. After maintenance, the above operation is repeated in reverse to install it back. The above is the complete usage of the dome steel structure connection structure.
