Abstract
The invention discloses a fish belly type longspan vierendeel truss structure which comprises upper chords, lower chords and a plurality of flaky web members, wherein the upper chords and the lower chords are arranged in the up and down manner, and the upper and lower chords and the flaky web members are rigidly connected to form an integral truss; the upper and lower chords are made from at least two pieces of closed section steel; the upper chords are located on a same horizontal plane and are supported and connected by horizontal upper chord supporting rods; the lower chords are in downward protruding arc-shapes; the flaky web members are annular. No diagonal web members are arranged, so that the structure is concise in shape; the plane is not limited to be linear and can be an arc-shaped, so that the modeling requirement can be realized well; the upper and lower chords are made from the structural steel which is combined with the rigid flaky web members, so that integral torsion can be effectively prevented to prevent overturn; the web members are rigidly connected with the chords, so that the structure has the relatively good redundancy; the vertical plane is in a fish belly shape, so that the structure meets a bending moment distribution rule, is reasonable in stress, has the relatively good rigidity and stability and is suitable for steel structures such as longspan overbridges, and corridors.
Description
Technical field
The present invention relates to a kind of fish-bellied type large span open-web truss structure, belong to large-span steel designed and calculated technical field.
Background technology
Large-span steel overline bridge, vestibule are widely applied in Modern Public Building and means of transportation.Form of structure choose and whether structure design proper directly determines overline bridge, the cost of vestibule, rigidity and stability, be also related to degree of safety and the comfortableness of the pedestrian of its carrying.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of fish-bellied type large span open-web truss structure, makes the simple for structure of overline bridge, vestibule, have good rigidity and stability.
For solving the problems of the technologies described above, the invention provides a kind of fish-bellied type large span open-web truss structure, it is characterized in that, comprise upper chord, lower chord and multiple sheet web member; Upper chord is positioned at top, and lower chord is positioned at below, and upper chord, lower chord and multiple sheet web member are rigidly connected integrally truss;
Upper chord, lower chord adopt the section profiled bar of remaining silent respectively being no less than two;
Many upper chords are in same level, and by winding up, horizontal support bar carries out support and connection;
Lower chord is the arc to lower convexity;
Sheet web member ringwise.
One end width that sheet web member is connected with upper chord is greater than the width of the one end be connected with lower chord, forms the annular of inverted triangle.
Only connected by sheet web member between upper chord, lower chord, in certain inclination angle between each sheet web member.
Overall truss end and bearing are rigidly connected, hinged or be slidably connected.
When overall truss end and bearing adopt be rigidly connected time, overall truss end is strengthened by end casing.
Upper chord is straight-bar or bow.
The projection of described lower chord middle part is straight-bar, and end becomes bow and is connected to the strong point.
Many upper chords each other, many lower chords are isometric or non-isometric each other.
The beneficial effect that the present invention reaches:
Fish-bellied type large span open-web truss structure of the present invention, is applicable to the steel work such as large span overline bridge and vestibule.
(1) do not have diagonal web member, profile is succinctly attractive in appearance, saves cost;
(2) plane is not restricted to linear pattern, can be arc-plane, better can realize modeling requirement;
(3) upper and lower chord member is shaped steel, is combined with rigid sheet web member, is highly resistant to overall torsion, prevents from toppling, have good rigidity and stability;
(4) web member and chord member just connect, and structure has good redundancy;
(5) facade is fish-bellied type profile, meets Bending moment distribution rule, reasonable stress, has good rigidity and stability.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, fish-bellied type large span Vierendeel truss of the present invention comprises pricncipal rafter 1, truss lower chord 2 and sheet web member 3, pricncipal rafter 1 is positioned at top, truss lower chord 2 is positioned at below, and upper chord 1, lower chord 2 and annular slice web member 3 are rigidly connected integrally truss.
Upper chord 1, lower chord 2 adopt the section profiled bar of remaining silent respectively being no less than two, and many upper chords 1 are in same level, and by winding up, horizontal support bar 4 carries out support and connection.Lower chord 2 is arc, the fish-bellied type shape in outwardly convex.
Ringwise, one end width be connected with upper chord 1 is comparatively large, and one end width be connected with lower chord 2 is less, forms the annular of inverted triangle for sheet web member 3.Only having sheet web member 3 to connect between upper chord 1, lower chord 2, can be certain inclination angle between each sheet web member 3.
Truss end according to support condition arrange just connect or hinged, the connected mode such as be slidably connected.When with bearing adopt just connect time, truss end is strengthened by end casing 5, thus makes total have good rigidity and stability.
Pricncipal rafter 1 can be straight-bar, also can be bow, and each upper chord can be isometric or non-isometric.
The projection of truss lower chord 2 middle part is straight-bar, and end becomes bow and is connected to the strong point; Each lower chord 2 can be isometric or non-isometric.
The structure of fish-bellied type large span open-web truss structure of the present invention is as following steps.Wherein relate to the type selecting of specific product, as whether component form of fracture, top-bottom chord line style, end arrange box reinforcement, and sheet web member incline direction etc., should be not limited to limit the scope of the invention.
(1) sheet web member 3 is prefabricated in the factory, and pricncipal rafter 1, truss lower chord 2 are prefabricated in the factory by transportation lengths;
(2) each mill work is transported to building-site;
(3) pricncipal rafter 1, truss lower chord 2, sheet web member 3 are assembled into overall truss in building site, can aloft assembly, also can after installation on ground completes Integral lifting;
(4) truss end is connected with braced structures;
(5) truss vertical deformation, torsional deflection etc. are detected.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
