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
The present invention relates to the new structure system in a kind of building structure, more particularly, relate to a kind of chord branch barrel shell structure system of forming by barrel shell, drag-line and strut in a kind of building structure.
Background technology
Cylindrical reticulated shell is a kind of latticed shell structure commonly used in the engineering, the architectural image grace, structure stress that it has a latticed shell structure rationally, calculation Design software maturation, processing mechanization degree advantages of higher.But when the building requirements structural span is big, the double-deck cylindrical reticulated shell that individual layer cylindrical reticulated shell or thickness are less is because self plane external stability is poor, thereby be difficult to realize bigger span, and when adopting bigger bilayer of thickness or multilayer cylindrical reticulated shell, also have following several respects deficiency:
(1) the net thickness of the shell is bigger, thereby makes the structural steel amount increase, and structural cost improves;
(2) net shell rise hour, the bearing horizontal thrust is big, causes burden to design of substructure.
(3) connection rod member in net shell node place is many, the joint structure complexity;
(4) because the net thickness of the shell is big, and rod member is long, assembled on site work is difficult for.
(5) because the number of plies is many, node is complicated, the inconvenience of must constructing;
Summary of the invention
In order to overcome deficiency of the prior art, the invention provides a kind of chord branch barrel shell structure system, it by the appropriate location at cylindrical reticulated shell strut is set and drag-line forms chord branch barrel shell structure system, on the one hand because the setting of drag-line, make overall structure rigidity increase, solved the less double-deck cylindrical reticulated shell of individual layer cylindrical reticulated shell or thickness owing to poor stability is difficult to cross over problem than large span; On the other hand, because barrel shell partly adopts individual layer or the less double-deck cylindrical reticulated shell of thickness, reduced steel using amount, the structure construction difficulty also reduces greatly.Because the setting of drag-line can be provided with pretension in drag-line, reduce the bearing horizontal thrust simultaneously, reduce the design of substructure burden.
Technical scheme of the present invention is as follows:
A kind of chord branch barrel shell structure system comprises barrel shell, strut, drag-line, anchorage node and turnover node.Described drag-line by anchorage node be connected with barrel shell, described drag-line by the turnover node be connected with the strut lower end, be connected with barrel shell on the described strut.
Described barrel shell can adopt the individual layer cylindrical reticulated shell structure, also can adopt the less double-deck cylindrical reticulated shell structure of thickness.
Described anchorage node can be arranged on barrel shell stride between or barrel shell support node place.
Described strut vertically can single vertical layout along barrel shell, or V-shaped layout.
Described strut can single-rowly be arranged along barrel shell span direction, or V-shaped layout.
The invention has the beneficial effects as follows, make full use of the good pressurized performance of barrel shell structure and the high-strength examining tensile behavior of cable body material, overcome the Double-level Reticulated Shell poor stability of individual layer barrel shell or thinner thickness, the shortcoming that span ability is little, form that a kind of span ability is big, good stability, economy rationally, the structural system of easy construction, can generally be applicable to general industrial and civilian construction, be specially adapted to large-span space structure systems such as conference and exhibition center, stadiums.

The specific embodiment
As shown in Figure 1, string props up the barrel shell structure and comprises barrel shell 1, drag-line 2, strut 3, anchorage node 4, turnover node 5, support node 6.Drag-line is connected with barrel shell by anchorage node, is connected with the strut lower end by the turnover node.The strut upper end is connected with barrel shell.
Barrel shell can adopt individual layer cylindrical reticulated shell or the less Double-level Reticulated Shell of thickness, and its span size, shape of cross section size can be determined according to building.Present embodiment adopts the individual layer cylindrical reticulated shell, shown in Fig. 1,4.
The big I of barrel shell size of mesh opening is determined according to structural span, the form of grid can adopt unidirectional brace quadrature square mesh, intersection brace quadrature square mesh, lamella, three-way grid or other grid arrangements, present embodiment adopts unidirectional brace quadrature square mesh, as shown in Figure 1, 2.
Strut can determine preferably that as calculated present embodiment is provided with 3 groups according to the span size along the group number that the span direction is provided with.Every group of strut can single-rowly be arranged along the span direction, shown in Fig. 4 (a), also can V-shapedly arrange, shown in Fig. 4 (b).
Strut vertically can singlely be arranged along barrel shell, shown in Fig. 5 (a), also can V-shapedly arrange, shown in Fig. 5 (b).
Drag-line can every two with a plurality of grids arrange vertically that along barrel shell present embodiment arranges one every three grids, as shown in Figure 1, 2, 3.
The anchorage node that drag-line is connected with barrel shell can be arranged on barrel shell and stride a position, also can be arranged on barrel shell support position place.Present embodiment is arranged on barrel shell and strides a position, shown in Fig. 1,2,3,4.
