Description
Technical field
The present invention relates to architectural engineering component, be a kind of combinative folded plate formula space truss beam.
Background technology
In architectural engineering in widely used steel construction, H profile steel is the principal mode of spandrel girder, requires to increase floor height, perforate on web, increase ribbed stiffener with welding, arrange bracing frame etc. generally according to using.Prolonged application finds, the deficiency of this H profile steel spandrel girder is: the anti-flexion capabilities of web of H profile steel is relatively low, limited by height and thickness ratio, when needing bigger shear-carrying capacity, anti-bending bearing capacity or requirement to have higher stability, web thickness must be increased, but, the result increasing web thickness is that steel using amount strengthens, weight is significantly increased, particularly local bearing capacity is unable to reach identical requirement, needing other parts to coordinate in engineer applied, on web, perforate easily reduces the bearing capacity of web for the method for drawing-in wire, and increases construction cost；When anchoring with concrete, the placement location of reinforcing bar needs strict design, designs and constructs the most high.
Summary of the invention
It is an object of the present invention to provide a kind of combinative folded plate formula space truss beam, it can solve the problem that the deficiencies in the prior art.
The present invention is for achieving the above object, it is achieved through the following technical solutions: a kind of combinative folded plate formula space truss beam, including upper wing bar and lower wing bar, several first oblique web and several second oblique web is connected between upper wing bar and lower wing bar, first oblique web one end is connected with upper wing bar, the other end is connected with lower wing bar, one end of second oblique web is connected with lower wing bar, the other end is connected with upper wing bar, several first parallel distributions of oblique web, several second parallel distributions of oblique web, the first angle α between the first oblique web and upper wing bar1More than 90 °, between each first oblique web and each second oblique web, the second angle α is set2, the second angle α2For acute angle.Cavity is set in the middle part of upper wing bar, in cavity, fills mortar or concrete.The cross section of upper wing bar is square type.The cross section of upper wing bar is c-type.The cross section concave groove type of upper wing bar.First oblique web one end and second oblique web one end are overlapped mutually merging and are connected with upper wing bar, and it is the first oblique web or the width of the second oblique web that the first oblique web and the second oblique web intersect the width L1 of overlapping.First oblique web one end and second oblique web one end are overlapped mutually merging and are connected with lower wing bar, and it is the first oblique web or the width of the second oblique web that the width L2 of overlapping is intersected in first oblique web one end and second oblique web one end.First oblique web one end and second oblique web one end are intersected, and arrange the 3rd angle α between the width of first oblique web one end and second oblique web one end intersecting lens and upper wing bar3.Second angle α2It it is 30 ° ~ 90 °.3rd angle α3It it is 35 ° ~ 65 °.
The invention has the advantages that: it is in addition to having fabulous stability in the large, the most fabulous local stability, each section of bearing capacity making girder truss is the most identical, when engineer applied, it is not necessary to increase other parts, girder truss can directly be used alone, reduce construction costs, and improve construction quality.Girder truss of the present invention is under web thickness same as the prior art, bearing capacity height 20%-40%, owing to the thickness of web is less, and fills the material such as mortar or concrete in upper wing bar and lower wing bar, steel using amount 20%-28% can be reduced while increasing the bearing capacity of girder truss.Girder truss Torsion bearing capacity 40%-60% higher than prior art of the present invention, shear-carrying capacity height 20%-30%, anti-bending bearing capacity height 40%-60%, in use middle need not arrange the rib increasing Torsion bearing capacity, also without arranging any structures such as bracing frame, making engineering design and construction simple, cost is greatly reduced.
