It is below in conjunction with accompanying drawing and specifically real for the purpose of this utility model, technical scheme and advantage is more clearly understood
Mode is applied, the utility model is described in further detail.It should be appreciated that embodiment described herein
Only to explain the utility model, the scope of protection of the utility model is not limited.
A kind of truss 10 as shown in Figure 1, including：At least two first top booms 11, at least first lower boom 12,
Connect the first web member 13 of the first top boom 11 and the first lower boom 12, be connected the second web member 14 of two first top booms 11；
First top boom, the 11 curved setting, first lower boom 12 are located at the lower section of two first top booms 11, and described
The section of truss 10 is in del.
The truss 10 is the support beam structure formed by rod member, for bearing pressure or pulling force.Present embodiment
The plane that first lower boom 12 of truss 10 and two first top booms 11 are formed in the same plane, does not make space
The truss 10 of stereochemical structure so that truss 10 is not only only capable of planar stress, but in whole solid space all directions all
Energy stress, makes whole truss 10 have greater stiffness；And the section of truss 10 is in inverted triangle, using the stability of triangle,
Improve the stability of truss 10；In addition, the 11 curved setting of the first top boom, the bearing capacity of truss 10 is further increased,
The big situation of span can be met, built suitable for multispan.First lower boom 12 is straight-bar, facilitates the first lower boom 12 and column
Connection.
Further, the section of the truss 10 is in isosceles triangle.
The projection of i.e. described first lower boom 12 is positioned at the centre of two first top booms 11, the first lower boom 12 to two
The distance of first top boom 11 is equal so that truss stress balance, stability are higher.
Further, the distance between described lower boom 12 of first top boom 11 and first, increased from truss both ends to centre
Greatly.
Because two first top booms 11 are arc, when the distance between the first top boom 11 and the first lower boom 12 are by two
Hold to centre and increase, i.e., described first top boom 11 is arch, the distance between the first top boom 11 and the first lower boom 12 two
Small broad in the middle, arch, which is set, makes the bearing capacity of the first top boom 11 stronger.
Further, first lower boom 12 is provided with pedestal (not shown).

It is larger in the span of truss 10, therefore present embodiment is additionally provided with intercolumniation link 33, the intercolumniation link 33 connects located at side column
Connect between frame 31 and center pillar link 32.The quantity of the intercolumniation link 33 can also make the appropriate adjustments according to span size, when
When span is larger, intercolumniation link 33 can suitably increase.
Further, the pulling force or pressure that need to be carried due to side column link 31 and center pillar link 32 are bigger, therefore, side
Post link 31 is with center pillar link 32 by two the second top booms, 301, two the second lower booms 302 and some connections each second
3rd web member 303 of the lower boom 302 of top boom 301 and/or second forms, and the side column link 31 and center pillar link 32
Section it is rectangular.
Further, the pulling force or pressure carried by intercolumniation link 32 is relatively small, therefore, the intercolumniation connection
Frame 32 is by two top booms 301 and a lower boom 302 and some each lower booms 302 of second top boom 301 and/or second of connection
The 3rd web member 303 form, and the section of the intercolumniation link 33 is triangular in shape.
Further, the link 30 is generally aligned in the same plane interior with the truss 10.
That is, each link 30 is welded to connect with truss 10, is located at same plane, reduces the thickness of roof system, is ensured
The stability of roof system, and welding robot can be used directly and welded, avoid using gusset plate, reduce artificial input and cost
Input, and ensure that crudy.
Further, the supporting construction 40 is the gable supporting construction located at the lower section of truss 10 at both ends.
The truss 10 in any of the above-described embodiment is used due to the roof system of present embodiment, ensure that the stress of truss 10 most
It is excellent, while each truss 10 is connected using link 30, the stability under loading of truss 10 is not only ensure that, and eliminate substantial amounts of branch
Support structure, it is only necessary to retain the gable supporting construction of the lower section of both ends truss 10, without setting tie-rod, horizontal support in addition or hanging down
The complicated supporting constructions such as allotment support, reduce steel using amount, and simplify technical process.
As shown in figure 3, present embodiment merely illustrates the supporting construction 40 of the one end of truss 10.
As shown in Figure 6 and Figure 7, the roof system of present embodiment also includes the steel column 50 on the first top boom 11, described
Length direction uniform intervals of the steel column 50 along the first top boom 11 are set.
The steel column 50 is moulding steel column, can be by setting and adjusting the length and set location of moulding steel column, to adapt to
Different architectural image requirements, and connected each steel column 50 by connection beam 52, so as to have stronger adaptability.
Further, the steel column 50 of present embodiment is vertically installed on two first top booms 11, by adjusting steel column
50 length, meets modeling requirement.
Further, in addition to steel column support bar 51, the steel column support bar 51 are located between each steel column 50.
In order to ensure the strength and stability of steel column 50, steel column support bar 51, the steel column are set between each steel column 50
Support bar 51 is arranged in a crossed manner, improving stability.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
