Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model unit truss body.
In figure: 1- unit truss body, 11- bolt sphere, 12- Drag link, 13- brace, 14- digonal link.
Specific embodiment
The technical solution of the utility model is described further below in conjunction with attached drawing, but required protection scope is not
It is confined to described；
The utility model provides a kind of steel structure net rack for gymnasium roof, as shown in Figure 1, including several nets
Frame cell cube 1, each unit truss body 1 are cube frame structure, and each unit truss body 1 includes being set to the cube
The bolt sphere 11 of frame apex and the Drag link 12 being set at the cube frame seamed edge, Drag link 12 and bolt sphere 11 it
Between first pass through screw thread pair connection weld together again.
Using the utility model technical solution, composition rack list is connected with a plurality of pull rod by using multiple bolt spheres
First body makes construction personnel in assembled roof construction, both can directly sling multiple unit truss bodies on building masonry wall
Several unit truss body assembly can also be become corresponding cell cube component on the ground in advance by assembly, then by these units
Body component is sling carries out assembly on building masonry wall, keeps the operation of construction personnel more flexible, and can according to need choosing
It is carried out with corresponding simple machine, without the heavy mechanical equipment for using expense high, advantageously reduces and be constructed into
This, in addition, the form-factor of each unit truss body is easily accomplished unanimously, convenient for assembling, to be applicable to a variety of roof structures
Consolidation service decreases the auxiliary process time for the assembled raw material that corresponding operating personnel searching matches, is conducive to shorten
Construction period improves construction efficiency, and pull rod first passes through screw thread pair with bolt sphere and connect, then welds together, and both ensure that rack
It is assembled also to facilitate progress for the overall structural strength and bearing capacity of cell cube.
