Description

Technical Field

[0001] The present invention relates to the technical field related to quick-assembly buildings, and particularly relates to a seismic joint structure for quick-construction buildings. Background Art

[0002] In the face of sudden natural disasters or the process of emergency rescue and disaster relief, it is often necessary to quickly build a building that can be applied to medical housing construction on site. Most of the structures of the currently common temporary hospitals are modular structures made by processing containers. Although such temporary buildings can meet common usage requirements, at most two modules can be transported by a flatbed truck, and the transportation occupies a large space, with strong limitations in use. It cannot be freely built according to the actual space requirements of the site like a quick-assembly building of steel structure type. The main reason restricting the development of the quick-assembly building of steel structure type is that each connection node is fixed by screwing bolts one by one, which is very troublesome to install and has a low production and installation efficiency on site.

A driving device and a locking device are installed in the column head 4;

[0020] The driving device includes driving platforms 5 arranged in parallel. An inclined first driving connecting rod 7 is arranged between the two driving platforms 5. Two groups of driving brackets are arranged on both sides of the first driving connecting rod 7. Each group of driving brackets is composed of two connecting rods 6. The two driving platforms 5 are connected and fixed into a whole through the connecting rods 6. Axial seats 8 are vertically installed at both ends of the first driving connecting rod 7. A turntable 9 that can rotate by fitting against the inner side surface of the column head 4 is installed on one side of the axial seat 8. A shaft tube 10 concentric with it is installed on one side of the turntable 9. One end of the shaft tube 10 passes through the column head 4 that is rotationally connected and matched with it and is screwed and connected with a nut 11. A driving gear 12 is fixedly installed on the shaft tube 10;

[0021] The locking device includes a shaft disc 13. A rotating shaft 14 that can slide in clearance with the key groove thereof is installed in the shaft disc 13. The upper end of the rotating shaft 14 passes through a positioning table 15 that slides in clearance with the key groove thereof and is axially butted with a driving platform 5 below. The positioning table 15 is rotationally connected and matched with the column head 4. A circle of external threads is arranged on the outer circumferential surface of the shaft disc 13. One of the driving platforms 5 above is rotationally connected and matched with the lower bottom surface of the upper column 2;

[0022] The column sleeve 3 as a whole is a tubular structure with an opening at the end facing the column head 4. A screw hole 16 that can be spirally matched with the shaft disc 13 is arranged at the bottom of the column sleeve 3. Slide grooves 17 for the shaft tube 10 to pass through are respectively opened on both sides of the column sleeve 3. A rack 18 that can be meshed and matched with the driving gear 12 is milled on one side of the slide groove 17;

[0023] The lower end of the rotating shaft 14 passes through the shaft disc 13 and is fixedly connected to the limit disc 19. A spring 20 is sleeved on the rotating shaft 14, and the upper and lower ends of the spring 20 respectively abut between the positioning platform 15 and the shaft disc 13.

[0024] The positioning platform 15 is an overall turntable with a concave cross-section. Second driving link rods 21 that can be rotationally connected and matched with it are respectively installed on both sides of the lower bottom surface of the positioning platform 15. The end of the second driving link rod 21 is installed with a third driving link rod 22 that is rotationally connected and matched with it.

[0026] The following further elaborates on the usage method and its principle of the technical solution part in this specific embodiment with reference to the attached drawings:

[0027] During docking, first vertically hoist the upper column 2 above the lower column 1, and then gradually lower the upper column 2 so that the column head 4 gradually moves into the column sleeve 3. During the process of the column head 4 being inserted into the column sleeve 3, the shaft tube 10 and the driving gear 12 gradually enter the chute 17 until the driving gear 12 starts to contact the rack 18 in the chute 17 and at the same time the shaft disc 13 also contacts the screw hole 16. As the column head 4 further descends, the driving gear 12, by means of the meshing cooperation with the rack 18, drives the first driving link rod 7 to deflect around the turntable 9 through the turntable 9 and the shaft seat 8. During the deflection of the first driving link rod 7, the driving platform 5 is driven to rotate through the driving bracket. Among them, the lower driving platform 5 drives the positioning platform 15 and the shaft disc 13 to rotate together during rotation. During the rotation of the shaft disc 13, it gradually screws into the screw hole 16. During the rotation of the positioning platform 15, the tooth 26 is gradually inserted and clamped on the inner wall of the column sleeve 3 through the second driving link rod 21 and the third driving link rod 22.
