Its use to the greatest extent.Also, research and practical earthquake show under earthquake shock effect that excessive displacement and acceleration responsive will cause knot
Structure destroys, and traditional truss structure does not have anti seismic efficiency, and structural stability is poor.In recent years, novel truss system is towards light weight
Change direction fast development, the truss structure of the rigid flexible system constructed with cable wire and carbon fibre member bar occurs, its advantage is that weight
Gently, structural behaviour is excellent, antifatigue etc., but specifically includes in practical engineering applications there is also some drawbacks：Only due to cable wire
It can bear, be unable to resistance to compression, therefore cable wire can only be arranged in and be solely subjected to tensile stress and without compression according to results of structural analysis
Above there is certain limitation at position in application；And assembly technology is complicated, and assembly process is lengthy and tedious；In use process, cable wire is easy
There is relaxation, prestressing force is caused to decline, and then influences the rigidity and bearing capacity of structure.
Utility model content
In view of the shortcomings of the prior art, the utility model provide it is a kind of be made of light section component it is light from energy dissipating from return
Type girder system, to solve the problem of that traditional truss fails material its use to the greatest extent from great consumption steel, and guarantee the rigidity of structure with
Under the premise of bearing capacity, meet the requirement of self- recoverage energy-dissipating and shock-absorbing.
The technical scheme in the invention for solving the above technical problem is：One kind is from energy dissipating from return light truss body
System comprising by light-duty steel member is welded or bolt consolidation form list Pin statically determinate truss, multiple list Pin statically determinate truss solid matters are passed through
Hingedly and more Pin statically determinate truss systems are fixedly connected to form, the list Pin statically determinate truss is the triangle of multiple light section components composition
Shape is disposed adjacent the single truss structure to be formed in the same plane.
Further, the light-duty steel member is combined steel pipe, and combined steel pipe includes the circular outside interconnected
Steel pipe and the inside steel pipe being set in external steel pipe.
Further, the inside steel pipe includes being set to external steel pipe centre and from each other using hinged side
Four center steel pipes of formula connection, center steel pipe periphery are evenly arranged with four peripheral steel pipes, peripheral steel pipe and adjacent center
Steel pipe just connects and external steel-pipe welding.
Compared with prior art, the advantages of the utility model has be：
1. the utility model on the basis of guaranteeing stiffness and strength, alleviates self weight, and have using light section structure rod piece
There is the function that can occur centainly to deform and reset, when in the girder system, mitigates integrally-built self weight significantly, drop
The low requirement to basis reduces the requirement to construction machinery under certain condition, mitigates operation intensity, while still improving and making
Industry efficiency；And the girder system is applicable to the bigger building structure of span due to alleviating self weight；
2. the truss structure of the utility model ties up to the space utilization rate for improving material to a certain extent；
3. in the girder system of the utility model each rod piece only by axle power and gravity laod effect under be not in tension and compression
Opposite sign can guarantee that each rod piece when large deformation occurs for structure, still there is clearly stress relationship；
4. in earthquake, since hinged between four, center of the light section structure rod piece steel pipe of composition girder system produces
Raw certain deformation（Displacement）The kinetic energy generated in absorption and dissipation seismic process, has the advantages that energy-absorbing damping.

Fig. 2 is the more Pin statically determinate truss structural schematic diagrams of the utility model；
Fig. 3 is light section member section structural schematic diagram.
Specific embodiment
The utility model is described further in the following with reference to the drawings and specific embodiments.
It is as shown in Figure 1, 2 a kind of from energy dissipating from return light truss system comprising welded by light-duty steel member 11
Or bolt consolidation composition list Pin statically determinate truss 1, multiple 1 solid matters of list Pin statically determinate truss form more Pin statically determinate truss systems 2, the list
Pin statically determinate truss 1 is that the triangle 13 that multiple light-duty steel members 11 form is disposed adjacent the single purlin Pin to be formed in the same plane
Frame.11 end of light-duty steel member is welded or the connection composition triangle 13 of bolt consolidated node 12, multiple triangles 13 exist
The single truss structure to form planar strip shape is disposed adjacent in same plane；Interval is set at the triangle fixed point of single Pin statically determinate truss 1
Rigid contact 14 and hinge joint 15 are set, rigid contact 14 and hinge joint 15 are formed for just connecing between list Pin statically determinate truss 1 and hingedly
More Pin statically determinate truss systems 2.
Further, the light-duty steel member 11 is combined steel pipe, and combined steel pipe includes the circular outer of interconnection
Portion's steel pipe 111 and the inside steel pipe being set in external steel pipe 111.
