Research on Installation and Construction Technology of Square Pyramid Bolt-sphere Joint Grid in Plateau Alpine Area
The orthogonal square pyramid grid structure is a kind of spatial bar structure with excellent overall stiffness and economic index.By arranging the bars according to the rules and connecting them with the bolt-sphere joints,the grid form is formed,which can maximize the span of the building space.In plateau alpine areas,the infrastructure construction is relatively weak and often accompanied by adverse environmental factors such as low temperature,large temperature difference and strong wind,which has a negative impact on the construction of large-span structures.Therefore,this paper starts from the initial stage,the high-altitude scattered assembly stage and the roof panel laying stage to study the construction technology of the square pyramid bolt-sphere joint steel structure in the plateau alpine area.
