Problems solved by technology

Therefore, generally speaking, no matter how rich the experience is, no matter how high the theoretical level is, the rationality of the structural form cannot be completely and objectively guaranteed, and it is quite difficult to find a reasonable structural form for more complex construction projects.

Embodiment Construction

[0013] Below with reference to accompanying drawing of description, the specific embodiment of the present invention is described in more detail:

[0014] Such as figure 1 As shown, a movable truss with a high-order curved shape is composed of a linkage mechanism and a cable. The linkage mechanism is composed of a plurality of four-bar linkage mechanisms 5. Two connecting rods 2, the third connecting rod 3 and the fourth connecting rod 4 are composed, and one end of the first connecting rod 1 is rotationally connected with one end of the second connecting rod 2, and the other end of the second connecting rod 2 is connected with the third connecting rod 3 is rotationally connected, the other end of the third connecting rod 3 is rotationally connected with one end of the fourth connecting rod 4, and one end of the fourth connecting rod 4 is rotationally connected with the other end of the first connecting rod 1. The four connecting rods The lengths of the first connecting rod 1...

Abstract

The invention discloses a truss structure with a high-order curve shape, comprising a connecting bar mechanism and an inhaul cable, wherein the connecting bar mechanism is obtained by interconnection of n four-connecting bar mechanisms by n-1 joints; the four-connecting bar mechanism is obtained by rotary connection of a first connecting bar, a second connecting bar, a third connecting bar and a fourth connecting bar; lengths of the first connecting bar and the fourth connecting bar are the same; lengths of the second connecting bar and the third connecting bar are the same; and lengths of the first connecting bar and the fourth connecting bar are longer than those of the second connecting bar and the third connecting bar. Because lengths of the first connecting bar and the second connecting bar in the connecting bar mechanism are different, in the movable truss, the joint of each sub connecting bar mechanism becomes arc during deformation; the corresponding geometrical shape is arc; and curvatures of the arcs change during the movement of the truss, so that the movable truss can form a geometrical shape with high-order curve.

Description

technical field [0001] The invention relates to a truss structure, in particular to a truss structure with a high-order curved shape. Background technique [0002] Long-span roof structures generally adopt curved structures, and curved structures are “shape-resistant” spatial structures that are closely related to architectural performance. The choice of curved surface structure not only affects the safety and economy of the building, but also directly affects all the requirements for the building such as usability and aesthetics. Currently, the curved surface structures that can be selected are limited to relatively simple geometric shapes (cylindrical, oblate spheroid, hyperbolic paraboloid, etc.), which cannot meet the ever-growing architectural performance requirements. The assumption of curved surface structure is artificial, and its rationality is closely related to the diversity, experience and knowledge level of designers, and the range of choices is also very narro...
