Description
Technical field
This utility model relates to architectural engineering component, is a kind of folded plate type girder truss.
Background technology
In architectural engineering in widely used steel construction, H profile steel is the principal mode of spandrel girder, wants generally according to using
Ask increase floor height, perforate on web, increase ribbed stiffener with welding, bracing frame etc. is set.Prolonged application finds, this H
The deficiency of shaped steel spandrel girder is: the anti-flexion capabilities of web of H profile steel is relatively low, is limited, when needs are bigger by height and thickness ratio
Shear-carrying capacity, anti-bending bearing capacity or requirement when having higher stability, it is necessary to increase web thickness, but, increase web thick
The result of degree is that steel using amount strengthens, and weight is significantly increased, and particularly local bearing capacity is unable to reach identical requirement, at engineer applied
Other parts of middle needs coordinate, and 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.
Utility model content
The purpose of this utility model is to provide a kind of combinative folded plate formula space truss beam, and it can solve the problem that prior art
Not enough.
This utility model for achieving the above object, is achieved through the following technical solutions: a kind of folded plate type girder truss, including on
Wing bar and lower wing bar, connect several first oblique web and several second oblique web, Mei Ge between upper wing bar and lower wing bar
One oblique web one end and each second oblique web one end are intersected and are connected with upper wing bar or lower wing bar, several first oblique abdomens
Be parallel to each other between plate distribution, several second oblique web mutual equality distributions.Between the first oblique web and the second oblique web
Second angle α is set2, the second angle α2It it is 45 °-75 °.The cross section of upper wing bar is square type.The cross section of upper wing bar is c-type.On
The cross section of wing bar is concave groove type.Merging is overlapped mutually with upper wing bar even in first oblique web one end and second oblique web one end
Connecing, it is the first oblique web or second oblique that the width L1 of overlapping is intersected in first oblique web one end and second oblique web one end
The width of web.First oblique web one end and second oblique web one end are overlapped mutually merging and are connected with lower wing bar, and first is oblique
It is the first oblique web or the width of the second oblique web that the width L2 of overlapping is intersected in web one end and second oblique web one end.
First oblique web one end and second oblique web one end are intersected, and first oblique web one end and second oblique web one end are intersected
3rd angle α is set between the width of line and upper wing bar3.3rd angle α3It it is 30 ° ~ 70 °
This utility model advantage is: it has fabulous stability in the large and local stability, makes each of girder truss
Section bearing capacity is the most identical, when engineer applied, it is not necessary to increasing other parts, girder truss can directly be used alone, and reduces engineering
Cost, and improve construction quality.Girder truss described in the utility model, under web thickness same as the prior art, carries
Power height 20%-40%, owing to the thickness of web is less, and fills the materials such as mortar concrete in upper wing bar and lower wing bar, can
While increasing the bearing capacity of girder truss, reduce steel using amount 20%-28%.Girder truss Torsion bearing capacity described in the utility model
Higher 405-60% than prior art, shear-carrying capacity height 20%-30%, anti-bending bearing capacity height 40%-60%, in use centre are not required to
The rib increasing Torsion bearing capacity is set, it is not required that arrange any structures such as bracing frame, makes engineering design and construction simple, become
Originally it is greatly reduced.
