Abstract
The invention relates to one form of spatial structure field application, concretely a cross braiding structure having top opening. The structure is formed by combining a plurality of plane truss units (1) which surround the top opening to form the shape of the top opening; and any plane truss unit is welded with an intersected plane truss unit. The structure of the invention has high bearing force, light self-weight, good appearance regularity, and beautiful shape.
Description
Technical field
The present invention relates to a kind of form that use in the space structures field, be specially top opening cross braiding structure.
Background technology
Building structure is the skeleton that bears, transmits the suffered various power of building.In recent years, space structures is because big from heavy and light, bearing capacity, development rapidly, people have been developed multiple novel space structures form.
When people when considering the novel space structures form of development, often be confined to the combination of various element of construction, as traditional thin shell structures, folded structure that constitutes by the plate shell unit, the latticed shell structure that constitutes by beam element, the space truss structure that constitutes by bar unit, suspended-cable structure that constitutes by cable elements etc., and the form of structure that forms by two or more unit combination, as the tension string beam structure that beam element and cable elements combine, cable dome structure that bar unit and cable elements combine or the like.
Along with the fast development of China's physical culture, cultural undertakings, the construction demand of physical culture, cultural building is also unprecedentedly surging.Often span is huge for a large amount of sport buildings, because the needs of match itself need be offered huge hole at dome, these construction conditionses have proposed great challenge all for the layout of structure simultaneously.
Summary of the invention
The invention provides a kind of top opening cross braiding structure, this braiding structure reconfigures the common planar trussed construction, arrange, is about to Plane truss element according to open-topped trend, around layout, intersect mutually, form the braiding shape, stressed jointly, constitute open-topped shape.
The technical scheme that the present invention takes is as follows: this braiding structure is combined by a plurality of Plane truss element, and a plurality of Plane truss element are looped around top open part, surrounds open-topped shape.Any one Plane truss element with the welding of its Plane truss element of intersecting, the crossover node of two Plane truss element ends is supported on the bearing.
When open top was shaped as circle or ellipse, Plane truss element was tangentially arranged.Angle between two adjacent arbitrarily Plane truss element is smaller or equal to 90 degree.
When open top was shaped as polygon, Plane truss element was arranged along polygonal length of side direction.
Described opening shape can be a polygon, also can be circular, oval or other shapes.
In this structure, the unit of plane frame becomes cross one another form around aperture arrangement, makes structure expand to three-dimensional stress by two-dimensional state, and Plane truss element can be communicated with, and also can block at opening annex place.
The present invention has the following advantages:
1) because the present invention is the combination of classical truss structural, given full play to the stressed uniform advantage of plane frame, structural bearing capacity is big, from heavy and light;
2) because the present invention is the combination of trussed construction, belong to the high order statically indeterminate system, rigidity is big, and resistance to overturning is good, and anti-seismic performance is good;
3) since the present invention when actual loading, many truss structures integrated carrying, thus can better adapt to local overload, mal-conditions such as unsymmetrical load, strong for asynchronous lifting or uneven settlement of foundation repellence in installing;
4) because trussed construction of the present invention centers on the open top symmetric arrangement, so overall structure is handsome in appearance, timing is strong, better regularity.

The specific embodiment
The invention will be further described below in conjunction with Fig. 1～6:
Embodiment 1:
As shown in Figure 2, the open top in the present embodiment is shaped as circle, and Plane truss element 1 evenly arranges along the tangential direction of circle, each Plane truss element with weld at the intersection point place with its Plane truss element that intersects.Simultaneously, structure can independent bearing also can constitute the dome structure of structure in seat supports such as crossover node 3 places of two Plane truss element ends and pillars.
Plane frame is around circular hole trend, and hoop arranges that each truss structure intersects mutually, promptly constitutes the interlacing structure.Truss can be according to stressed needs, and the form that is arranged to lead directly to also can be blocked at opening part, to avoid too complicated stressed of opening part.
The quantity of Plane truss element, intersecting angle, can be according to practical structures stressed and outward appearance needs arrange that the angle of cut of every adjacent two Plane truss element is all less than 90 degree in the present embodiment.
The structure of Plane truss element as shown in Figure 1, a is a pricncipal rafter, b is the truss lower chord, c is a truss web, the connected mode between the three is hinged.
Embodiment 2:
The structure of present embodiment and embodiment 1 is basic identical, difference only is the open-topped rectangle that is shaped as, and as shown in Figure 3, single Plane truss element is arranged along the length of side direction of rectangle, two adjacent Plane truss element become 90 degree, and weld at the node place that intersects.
Embodiment 3:
The structure of present embodiment and embodiment 1 is basic identical, and difference only is the open-topped hexagon that is shaped as, and as shown in Figure 4, single Plane truss element is arranged along hexagonal length of side direction.
Embodiment 4:
The structure of present embodiment and embodiment 1 is basic identical, and difference only is the open-topped polygon that is shaped as, and as shown in Figure 5, single Plane truss element is arranged along polygonal length of side direction.
Embodiment 5:
The structure of present embodiment and embodiment 1 is basic identical, and difference only is the open-topped ellipse that is shaped as, and as shown in Figure 6, single Plane truss element is arranged along oval-shaped tangential direction.
