Problems solved by technology

[0008] In order to overcome the deficiencies in the prior art, the present invention provides a chord tube shell structure system, which forms a chord tube shell structure system by arranging struts and cables at appropriate positions of the cylindrical reticulated shell. On the one hand, due to the The setting increases the rigidity of the overall structure, which solves the problem that the single-layer cylindrical reticulated shell or the double-layer cylindrical reticulated shell with small thickness is difficult to span a large span due to poor stability; Layer or double-layer cylindrical reticulated shell with small thickness reduces the amount of steel used and the difficulty of structural construction is also greatly reduced

Embodiment Construction

[0021] Such as figure 1 As shown, the chord shell structure includes a shell 1 , a stay cable 2 , a strut 3 , an anchor node 4 , a turning node 5 , and a support node 6 . The stay cable is connected to the shell through the anchor node, and connected to the lower end of the strut through the turning node. The upper end of the strut is connected with the shell.

[0022] The cylindrical shell can be a single-layer cylindrical reticulated shell or a double-layer reticulated shell with a small thickness, and its span size and cross-sectional shape can be determined according to the building. This embodiment uses a single-layer cylindrical reticulated shell, such as figure 1 , 4 shown.

[0023] The grid size of the cylinder shell can be determined according to the structural span, and the form of the grid can be a one-way diagonal bar orthogonal square grid, a cross diagonal bar orthogonal square grid, a joint square grid, a three-way grid or other grids Arrangement method, th...

Abstract

The invention discloses a shell-structure system of a sting-supported cylinder, which comprises a shell, a supporting rod, an inhaul cable, an anchoring node and a turning node. The shell can adopt a net-shell structure with single-layer cylinder surface or with double-layer cylinder surface. The inhaul cable can be connected to the node in the cross cylinder-shell space or to a support. The inhaul cable is connected with the lower part of the supporting rod through the turning rod, and the upper part of the supporting rod is connected to the shell so as to form the shell-structure system of a string-supported cylinder. The shell-structure system of a sting-supported cylinder has the advantages of overcoming the bad stability of single-layer cylinder shell or the thiner double-layer net shell and small striding ability through fully making use of the good compression performance of the shell and high-strength tensile performance of cable material, the shell-structure system of a sting-supported cylinder, being a structure system with large spanning ability, good stability, rationality, economy and convenient application, being universally applied to the common industrial and civil buildings, in particular to the structure system with large span such as convention center and stadium.

Description

technical field [0001] The invention relates to a novel structural system in a building structure, more specifically, to a string-supporting cylindrical shell structure system in a building structure consisting of a cylindrical shell, a stay cable and a brace. Background technique [0002] Cylindrical reticulated shell is a kind of reticulated shell structure commonly used in engineering. It has the advantages of beautiful architectural shape of reticulated shell structure, reasonable structural force, mature calculation and design software, and high degree of mechanization of processing. However, when the building requires a large structural span, it is difficult to achieve a large span due to the poor stability of the single-layer cylindrical reticulated shell or the double-layer cylindrical reticulated shell with a small thickness. Or multi-layer cylindrical reticulated shells, there are also the following deficiencies: [0003] (1) The thickness of the reticulated shell...
