However, this device is prone to shaking of the upper support after being subjected to vibration, which affects the stability of the building beams or the roof. There is an urgent need for a column-top connection structure for large-span buildings to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a column top connection structure for a large-span building, including a large-span building column body 1, a connecting cylinder 4 at the upper end of the large-span building column body 1, a building connecting beam 5 fixedly connected to the upper end of the connecting cylinder 4, an upper sliding head 9 fixedly connected to the lower end of the building connecting beam 5, a lower sliding seat 10 fixedly connected to the upper end of the large-span building column body 1, and four sets of seismic-resistant components between the building connecting beam 5 and the large-span building column body 1, one set of seismic-resistant components including two positioning tubes 7, a spring 8, multiple mounting seats 11, multiple fixing sleeves 12, and... Multiple rotating balls 14 and two positioning tubes 7 are respectively fixedly connected to the upper ends of the building connecting beam 5 and the large-span building column body 1. A spring 8 is fixedly connected to the lower end of the building connecting beam 5. Multiple mounting seats 11 are respectively fixedly connected to the upper and lower ends of the building connecting beam 5 and the large-span building column body 1. Multiple fixed sleeves 12 are respectively fixedly connected to the upper and lower ends of the mounting seats 11. Multiple rotating balls 14 are respectively rotatably connected to multiple fixed sleeves 12. This design solves the problem that the original device is prone to shaking of the upper support after being subjected to vibration, thus affecting the stability of the building beam or ceiling.

[0023] As the first embodiment of this utility model: a limiting stop tube 3 is fixedly connected to the surface of the large-span building column body 1. Fixed ribs 2 are fixedly connected to both the front and rear ends of the large-span building column body 1. The limiting stop tube 3 installed on the surface of the large-span building column body 1 can limit the connecting cylinder 4 to the surface of the large-span building column body 1. The connecting cylinder 4 can be fixedly connected to the large-span building column body 1 by bolts. The fixed ribs 2 installed on the surface of the large-span building column body 1 can enhance the overall strength of the large-span building column body 1, enabling it to stably fix the building connecting beam 5. Fixed rib plates 6 are fixedly connected to both the left and right ends of the building connecting beam 5 and the connecting cylinder 4. Multiple sets of rotating balls 14 cooperate and rotate together. The fixed rib plates 6 installed at both ends of the building connecting beam 5 and the connecting cylinder 4 can enhance the firmness of the building connecting beam 5 and the connecting cylinder 4. When the building connecting beam 5 is connected to the large-span building column body 1, the multiple sets of rotating balls 14 can cooperate and connect, thereby reducing the impact on the building connecting beam 5 and the large-span building column body 1. The sliding seat 10 and the upper sliding head 9 cooperate with each other. The large-span building column body 1 and the limiting stop tube 3 are fixedly connected by threads. The upper sliding head 9 swings within the sliding seat 10, and the impact is absorbed by the spring 8 and multiple rotating balls 14, thereby increasing the toughness of the building connecting beam 5 and the large-span building column body 1. The surfaces of the sliding seat 10 and the upper sliding head 9 are provided with a lubricating oil layer, which can reduce the wear between the sliding seat 10 and the upper sliding head 9, thereby increasing the service life of the upper sliding head 9 and the sliding seat 10. Multiple limiting baffles 13 are fixedly connected to the upper end of the large-span building column body 1. The limiting baffles 13 installed on the large-span building column body 1 can limit the rotating balls 14 to be installed in the fixed sleeve 12.

[0024] As a second embodiment of this utility model: First, the connecting cylinder 4 is fitted onto the surface of the large-span building column body 1, and then the connecting cylinder 4 and the large-span building column body 1 can be fixedly connected by bolts. At the same time, the upper sliding head 9 is positioned in the lower sliding seat 10. When the building connecting beam 5 and the large-span building column body 1 are shaken by external impact, the building connecting beam 5 and the large-span building column body 1 can absorb the impact under the elastic force of the spring 8. At the same time, multiple rotating balls 14 rotate and cooperate with each other to prevent the building connecting beam 5 and the large-span building column body 1 from shifting.
