Problems solved by technology
Due to the lack of corresponding technical standards for the external floating eaves and ceiling system, the external overhanging eaves of some space structures adopt the indoor ceiling technology, resulting in large-scale collapse and injury of the suspended ceiling under strong wind conditions

Embodiment
[0043] refer to figure 1 As shown, the external overhanging ceiling system structure of the space structure provided by this embodiment includes a support column 1 , a main keel 2 , an auxiliary keel 3 , a movable hinge mechanism 4 and a Z-shaped connector 5 .
[0044] Wherein, one end of the support column 1 is fixed on the ceiling support 100 of the lower string ball node, the other end of the support column 1 and the main keel 2 are fixedly installed by bolts, and the auxiliary keel 3 is connected with the main keel 1 through the movable hinge mechanism 4 , to realize arbitrary up and down rotation, and the auxiliary keel 3 is also framed with the Z-shaped connector 5 through the other end of the movable hinge mechanism 4, so as to realize the three-dimensional adjustment of the ceiling system.
[0045] It can be seen that the structure of the external overhanging eaves and ceiling system of this space structure uses support columns to replace the traditional suspenders and...

The invention discloses a structure and a construction method of a space structure external cornice ceiling system. The structure includes a support column, a main keel, an auxiliary keel, an articulation mechanism and a Z-type connector. One end of the support column is fixed to a ceiling support of a lower chord ball joint, and the other end of the support column is fixedly installed on the mainkeel by bolts. The auxiliary keel is connected with the main keel through one end of the movable articulation mechanism so as to realize arbitrary up-and-down rotation. The auxiliary keel and the Z-type connector form a frame through the other end of the movable articulation mechanism so as to make the ceiling system adjustable in three dimensions. According to the space structure external cornice ceiling system, the support column instead of the traditional boom is connected with a lower chord ball joint plate of a net rack to withstand external wind load. Meanwhile, the space structure external cornice ceiling system adopts a 'joint' movable connecting plate articulation mechanism to realize three-dimensional adjustment of the ceiling. Therefore, all the movement caused by the stresseddeformation of the net rack can be accommodated, and the hyperboloid shape of the ceiling is satisfied.
Description
technical field [0001] The invention relates to the technical field of building assembly, in particular to a system structure and a construction method of a space structure external overhanging eaves and suspended ceiling. Background technique [0002] At present, the external overhanging ceiling system of large-span space structures such as large-scale terminals, stadiums, and exhibition halls has been widely used. The external floating eaves and ceiling system of the long-span space structure must not only be able to bear the external wind load, but also accommodate all the movements caused by the deformation of the grid structure (snow load, wind load, temperature internal force, earthquake load, etc.). Due to the lack of corresponding technical standards for the external floating eaves and ceiling system, the external overhanging eaves of some space structures adopt the indoor ceiling technology, resulting in large-scale collapse and injury of the suspended ceiling under...
