Abstract
The utility model discloses a kind of large-span truss structure, it relates to a kind of trussed construction.It comprises the plane web member that winds up, facade web member, upper chord, lower chord, lower edge plane web member, be provided with between upper chord and intersect and the parallel plane web member that winds up, be provided with between lower chord and intersect and parallel lower edge plane web member, parallel facade web member is provided with between the upper chord of homonymy and lower chord, the upper chord of heteropleural and lower chord are provided with the facade web member of intersection, and in the described plane web member that winds up, facade web member, upper chord, lower chord, lower edge plane web member, any three form triangle rock-steady structure.The utility model structure is simple, and good stability, cross section torsional property is good, practical.
Description
Technical field
The utility model relates to a kind of trussed construction, be specifically related to a kind of large-span truss structure.
Background technology
There are some defects in traditional large-span truss structure: due to web member and chord member self, make the cross section resistance to torsion of the pole of truss poor, and the stability of truss is not high yet, reduce its enabling capabilities, application life is not long, greatly reduces its result of use, and the scope of application is wideless.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind of large-span truss structure, and structure is simple, and good stability, cross section torsional property is good, practical.
To achieve these goals, the utility model realizes by the following technical solutions: a kind of large-span truss structure, comprise the plane web member that winds up, facade web member, upper chord, lower chord, lower edge plane web member, be provided with between upper chord and intersect and the parallel plane web member that winds up, be provided with between lower chord and intersect and parallel lower edge plane web member, parallel facade web member is provided with between the upper chord of homonymy and lower chord, the upper chord of heteropleural and lower chord are provided with the facade web member of intersection, the described plane web member that winds up, facade web member, upper chord, lower chord, in lower edge plane web member, any three form triangle rock-steady structure.
As preferably, in described upper chord, lower chord, a pole adopts three-dimensional hinged, and all the other poles adopt two to hinged, this is because space truss longitudinally has certain flexible under load effect, longitudinally not to impose restriction power like this along space truss.
As preferably, the described plane web member that winds up, facade web member, upper chord, lower chord, lower edge plane web member all adopt square tube or pipe.
Described facade web member can be replaced annulus, also can increase the stability of truss.
The beneficial effects of the utility model: structure is simple, and good stability, cross section torsional property is good, practical.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is plane structure schematic diagram of the present utility model;
Fig. 2 is one section of three-dimensional structure diagram of the present utility model.
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
With reference to Fig. 1-2, this detailed description of the invention is by the following technical solutions: a kind of large-span truss structure, comprise the plane web member 1 that winds up, facade web member 2, upper chord 3, lower chord 4, lower edge plane web member 5, be provided with between upper chord 3 and intersect and the parallel plane web member 1 that winds up, be provided with between lower chord 4 and intersect and parallel lower edge plane web member 5, parallel facade web member 2 is provided with between the upper chord 3 of homonymy and lower chord 4, the upper chord 3 of heteropleural and lower chord 4 are provided with the facade web member 2 of intersection, the described plane web member 1 that winds up, facade web member 2, upper chord 3, lower chord 4, in lower edge plane web member 5, any three form triangle rock-steady structure.
It should be noted that, in described upper chord 3, lower chord 4, a pole adopts three-dimensional hinged, all the other poles adopt two to hinged, this is because space truss longitudinally has certain stretching under load effect, like this along the longitudinal power that do not impose restriction of space truss.
In addition, the described plane web member 1 that winds up, facade web member 2, upper chord 3, lower chord 4, lower edge plane web member 5 all adopt square tube or pipe.
This detailed description of the invention, by three-legged structure or circular frame structure, substantially increases the stability of truss, and adopts pipe or square tube, its cross section torsional property is good, and result of use is better, substantially increases its application life, and it is relatively simple for structure, easy to use and reliable, practical.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
