Abstract
The invention discloses a triangular steel tube truss structure which comprises upper chord members, lower chord members, structural web members, upper wind bracing web members, support legs, H-section steel and guardrails. Flanges are welded at two ends of each upper chord member, the upper chord members are connected with one another by bolts, flanges are welded at two ends of each lower chord member, the lower chord members are connected with one another by bolts, steel plates are welded on the upper chord members and the lower chord members respectively, flanges and steel plates are welded at two ends of each structural web member, flanges and steel plates are welded at two ends of each upper wind bracing web member, the structural web members are connected with the upper chord members and the lower chord members by bolts, the upper wind bracing web members are connected with the upper chord members and the lower chord members by bolts, the support legs are welded with the upper chord members, the H-section steel is connected with the upper chord members by bolts, and the guardrails are welded with the H-section steel. The triangular steel tube truss structure has the advantages that the triangular steel tube truss structure is reasonable, machining procedures can be reduced, the labor intensity can be lowered, the work efficiency can be improved, steel consumption can be decreased, and the production cost can be saved.
Description
Technical field
The present invention relates to a kind of triangle steel tube truss structure.
Background technology
Only be subject to the desirable hinge system that waits straight-bar of nodal load effect to claim trussed construction.It is that the abstract simplification of engineering structures that meets at any by some bar axles forms.Truss is seen at first practicality on construction wooden bridge and roof truss.Truss can be classified by different features.One, according to the profile of truss, be divided into: 1. parallel chord truss (is convenient to arrange double-decker; Be beneficial to standardized production, but stick force distribution is even not); 2. curved chord truss (as parabola shaped girder truss, outward, just as the bending moment diagram of simply supported beam under evenly distributed load, stick force is evenly distributed, and materials'use economy is constructed more complicated); 3. triangular truss (it is more inhomogeneous that stick force distributes, structure difficult arrangement, but inclined-plane meets roof drainage needs).Two, with truss how much building forms, divide: 1. simple truss (increasing successively diploid by a basic hinge knot triangle forms); 2. combine truss (being constituted jointly by the simple composition rule of geometrically stable system by several simple trusses); 3. complex truss (other statically determinate truss that is different from first two).Three, by suffered horizontal thrust, divide: 1. without the girder frame of thrust (with corresponding real girder construction comparison, empty rate large, top-bottom chord bending resistance, the main shearing resistance of web member, reasonable stress, uses material economy); 2. the arch truss (span ability is strong for arch ring and the spandrel structure good integrity that combines as a whole, constructability, saves Steel material) that has thrust.Triangle steel tube truss structure of the present invention, rational in infrastructure, reduced manufacturing procedure, reduced labour intensity, improved operating efficiency, reduced rolled steel dosage, saved cost of production.
Summary of the invention
The object of this invention is to provide a kind of triangle steel tube truss structure.
The object of the invention is to be achieved through the following technical solutions:
Triangle steel tube truss structure of the present invention, comprises upper chord, lower chord, structure web member, upper wind brace web member, support leg, i iron and guardrail.Upper chord two ends are welded with flange, between upper chord, be bolted, lower chord two ends are welded with flange, between lower chord, be bolted, on upper chord, be welded with steel plate, on lower chord, be welded with steel plate, structure web member two ends are welded with flange and steel plate, upper wind brace web member two ends are welded with flange and steel plate, structure web member and upper chord and lower chord are all bolted, and upper wind brace web member and upper chord and lower chord are all bolted, support leg and upper chord welding, i iron and upper chord are bolted, guardrail and i iron welding.
As seen from the above technical solution provided by the invention, triangle steel tube truss structure of the present invention, rational in infrastructure, reduced manufacturing procedure, reduced labour intensity, improved operating efficiency, reduced rolled steel dosage, saved cost of production.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of triangle steel tube truss structure;
Fig. 2 is triangle steel tube truss structure side-looking structural representation;
Fig. 3 is triangle steel tube truss structure wind brace structural representation.
The specific embodiment
Triangle steel tube truss structure of the present invention, its preferably the specific embodiment as shown in Figure 1, Figure 2, Figure 3 shows, triangle steel tube truss structure comprises upper chord 1, lower chord 2, structure web member 3, upper wind brace web member 4, support leg 5, i iron 6 and guardrail 7.
Upper chord 1 two ends are welded with flange, between upper chord 1, be bolted, lower chord 2 two ends are welded with flange, between lower chord 2, be bolted, on upper chord 1, be welded with steel plate, on lower chord 2, be welded with steel plate, structure web member 3 two ends are welded with flange and steel plate, upper wind brace web member 4 two ends are welded with flange and steel plate, structure web member 3 is all bolted with upper chord 1 and lower chord 2, upper wind brace web member 4 is all bolted with upper chord 1 and lower chord 2, support leg 5 and upper chord 1 welding, i iron 6 is bolted with upper chord 1, guardrail 7 and i iron 6 welding.
Triangle steel tube truss structure of the present invention has following innovative point:
The upper chord of triangle steel tube truss structure, lower chord, structure web member and upper wind brace web member all adopt steel pipe, can effectively reduce rolled steel dosage, have saved cost of production.
Beneficial effect of the present invention
Rational in infrastructure;
Reduce manufacturing procedure, reduced labour intensity;
Improved operating efficiency;
Reduce rolled steel dosage, saved cost of production.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.
