Embodiment Construction

[0021] Such as Figure 1-3 As shown, the present invention includes an arch rib 1, a stay cable 2, a strut 3, a single-layer reticulated shell and a reticulated shell rod 4;

[0022] The arch rib 1 adopts a staggered string structure, that is, the arch rib is an intersecting parabola, and the projection of the intersecting parabola on a plane is a rectangular diagonal;

[0023] The number of the single-layer reticulated shells is four, the single-layer reticulated shells are arranged between intersecting parabolas, and the projections of the four single-layer reticulated shells on the plane are four triangles formed between the diagonals of the rectangle;

[0024] One end of the dragline 2 is connected to the upper end of the strut 3, and the other end of the dragline 2 is connected to the arch rib 1 or another strut;

[0025] The lower end of the strut 3 is connected to the arch rib 1, and the upper end of the strut 3 is connected to one end of the cable 2;

[0026] The two...

Abstract

The invention discloses an assembling type string-tensioning arch rib latticed shell structure suitable for a rectangular plane. The assembling type string-tensioning arch rib latticed shell structure comprises parabolic string-tensioning arch ribs along the diagonal direction of the rectangular plane and four single-layer rigid latticed shells between the arch ribs, wherein the single-layer rigid latticed shells with triangular planar projection between the arch ribs are selected from a part of a cylindrical latticed shell and the single-layer rigid latticed shells are hinged with the arch ribs through pin shafts. According to the assembling type string-tensioning arch rib latticed shell structure, through the pre-stress tension, a pretension force is established in a stay rope and a support rod; the structure is simple; the appearance is beautiful; the force-transferring path is clear; the flexural rigidity of the arch ribs can be fully utilized; the prefabricating construction can be conveniently performed.

Description

technical field [0001] The invention relates to a space structure of civil engineering, in particular to an assemblable string-arch rib reticulated shell structure suitable for a rectangular plane. Background technique [0002] Suspension dome is an important spatial structure system, which is widely used in long-span spatial structures because of its beautiful shape and simple and reasonable structural form. [0003] The suspension dome is composed of the upper single-layer reticulated shell, the lower vertical struts, radial rods or stay cables and hoop stay cables, in which the upper end of each ring strut is hinged with the ring nodes corresponding to the single-layer reticulated shell. The lower ends of the rods are connected to the nodes of the next ring of the single-layer reticulated shell by radial cables, and the lower ends of the struts of the same ring are connected together by annular cables, so that the entire structure forms a complete system, and the force tr...
