Unfoldable cylindrical lattice shell structure with six rigid plate folding units

Abstract

The invention discloses an unfoldable cylindrical lattice shell structure with six rigid plate folding units. The unfoldable cylindrical structure is composed of multiple truss folding arch units which are connected in the length direction; each truss folding arch unit is provided with a rigid roof plate unit system; a rigid roof plate unit is arranged on two adjacent rectangular pyramid basic units in the folding arch unit; each rigid roof plate unit consists of six triangular plates and is rectangular after being unfolded, every two of the six triangular plates are collinear and intersect at one vertex, and according to anticlockwise direction, the six triangular plates are respectively a first triangular plate, a second triangular plate, a third triangular plate, a fourth triangular plate, a fifth triangular plate and a sixth triangular plate. Compared with the existing structure, the unfoldable cylindrical lattice shell structure can be unfolded and folded according to needs, and is convenient in unfolding and folding process and good in structural stability; by virtue of the rigid roof structure, the unfoldable cylindrical lattice shell structure is relatively light in self weight, flexible to unfold and fold, the structure rigidity is increased, and the unfoldable cylindrical lattice shell structure is simple in structure construction and convenient in design and construction, and is especially suitable for medium and small span buildings.

Description

technical field [0001] The invention relates to a folded cylindrical reticulated shell structure with rigid roof panels, in particular to an expandable cylindrical reticulated shell structure with six rigid plate folding units. Background technique [0002] The folding structure roof conforms to the contemporary architectural concept, and is a major development trend of the large-span space structure, and it is more and more favored by people. Folding structures have aroused great interest of modern architects because of their advantages such as short construction period, easy relocation and reusability. However, it is rarely used in long-span structures. The main reasons are as follows: (1) The node design of folded grid structures is generally complicated, and there is still a lack of simple, practical, and low-cost node designs suitable for engineering applications; (2) In addition to the axial force, the members of the folded grid structure are subject to a certain bend...

However, it is rarely used in long-span structures. The main reasons are as follows: (1) The node design of folded grid structures is generally complicated, and there is still a lack of simple, practical, and low-cost node designs suitable for engineering applications; (2) In addition to the axial force, the members of the folded grid structure are subject to a certain bending moment, the mechanical performance is not good, and the cost is high; (3) The stiffness of the folded grid structure is very poor, and the displacement is difficult to meet the use requirements
