Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, referring to the drawings and enumerate excellent
Embodiment is selected, the utility model is further described.However, it is necessary to illustrate, many details listed in specification
Just for the sake of making one or more aspects of the reader to the utility model, there are one thorough explanations, specific even without these
Details can also realize the utility model these aspect.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of roofing Elements of Space Grid Truss, which is characterized in that the roofing Elements of Space Grid Truss by several Pin length not
Structure of the one sub- Elements of Space Grid Truss splicing composition plane for ellipse, an every Pin Elements of Space Grid Truss is by top boom 10, lower boom 9, web member 8
Several quadrangular pyramid units of composition are spliced；The top boom 10, lower boom 9, web member 8 each rod piece between pass through
Bolt sphere connects, and the bolt sphere is divided into bolt sphere 6, lower bolt sphere 7, and upper bolt sphere 6 connects web member 8 and top boom 10,
Lower bolt sphere 7 connects web member 8 and lower boom 9, and an every Pin Elements of Space Grid Truss is as shown in fig. 6, shown in fig. 6 is every Pin
The planar structure schematic diagram of Elements of Space Grid Truss.In order to more intuitively show the structure of Fig. 1, A-A faces and B-B faces structure in Fig. 1 are provided
Sectional view, as shown in Figure 5, Figure 6.
Preferably, the roofing Elements of Space Grid Truss elliptic plane size is 81*68.4m.
Preferably, the bolt ball surface is uniformly and symmetrically distributed several bolts hole, the bolt hole be used for web member 8 or
The upper and lower chord member 9 of person connects.
As shown in Figure 3, Figure 4, bolted spherical node net is formed after the bolt sphere is connect with upper and lower chord member 9 and web member 8
Frame, the grid structure with bolt-sphere joints are made of bolt sphere, rod piece 16, sleeve 18 and high-strength bolt 15；The rod piece 16 winds up
Containing conehead, high-strength bolt 15 is connected as a single entity bolt sphere, sleeve 18 and rod piece 16 from inside for bar 10 or lower boom 9 or web member 8,
The correspondence of high-strength bolt 15 is screwed into bolt hole.It, should be by the positioning stove bolt on sleeve 18 after Elements of Space Grid Truss high-strength bolt 15 fastens
Tighten locking.
