Summary of the invention:
Characteristics of this program are applying prestressing force using " hinge " (the containing rigid hinge, semi-rigid hinge, flexible hinge) that is set to node,
To reach the bearing capacity for improving works, and the purpose of saving steel, the support end of all kinds of hinges must be solid and reliable, absolutely not
It can be displaced.
This programme to structural unit body apply prestressing force (pressurization), and at node " hinge " consolidate after, the structure list
First body has good stability.The works for being readily transported and assembling, and assemble has prestressing force feature.
This programme adaptability is extensive, and structural unit body can be assembled into the truss compared with large span, also can be by structural unit
Body is assembled into rack, latticed shell structure.Structural unit side is depending on that can be of a straight line type, with acclive linear type or shaped form.Its
I-shaped, square, square type, ladder type, triangular form or combined X-Y two-dimensional space can be presented in section, or is in X-Y-Z tri-
Dimension space.With preferable flexibility, variability.
The combined application of prestressed " hinge " and portal-rigid frames can be applied.
Structures and enclosed structure with extra space also can be assembled in this programme structural unit body.
A large amount of engineering practices show that the prestressing force of cable wire can be made when we apply prestressing force to a girder system
For lower edge, and it is made to generate compression.This external force intervention can also promote entire girder system to generate corresponding adjustment,
That is the upper chord node of truss has microlitre and the appearance of tensile stress；And the adjustment of web member ess-strain.--- this be truss from
The adjustment of stress, to keep the monolithic stability of truss.This phenomenon shows our the appropriateness interventions to girder system, will not destroy
The stability of truss whole system.It is simultaneously also to improve girder system bearing capacity, and the important means to save material.
For the understanding of above-mentioned phenomenon；--- our interventions to the appropriateness of structural unit body must be improved
Its bearing capacity, the important means to save material.
Therefore obtaining one has the structural unit body for stablizing prestressing force effect, and performance can apply prestressed " hinge " and tie
Effect in the combination of structure object has important actual benefit.
To the Preliminary study of this programme see Figure of description, it can be seen that from diagram and the hinge being located at the node that winds up imposed
Prestressing force can make to wind up to generate tensile stress；Prestressing force is imposed to the hinge being located at lower-chord panel point, lower edge can be made to generate compression.
Therefore the works (such as grid structure) combined by structural unit body will receive structural unit body after bearing external loads first
Prestressed resistance, after only exhausting this prestressing force, the material (steel) of composed structure object is just born from external loads
Effect.
Structural unit body is more than when bearing external loads and affects the variation winded up with lower edge power, can similarly promote
The stress of c and c ' series rod piece generates the change of sign.
But also it should be seen that keeping b, b ' series and a, a ' system of lower-chord panel point of diagonal web member d, d ' series and upper chord node
The direct channel for arranging " power " is most important, is the key that guarantee that structural unit body works normally.
