Abstract
The invention discloses a kind of V-arrangement truss, comprise two upper chords, a lower chord and Duo Gen web member, described web member is arranged between described upper chord and described lower chord, the two ends of described web member are respectively connected with described lower chord with described upper chord by a connected node, and the shape of cross section of this truss is V-arrangement; The axis of described upper chord is planar arc or broken line, and the axis of described lower chord is straight line or planar arc or broken line, and two described upper chords and a described lower chord are intersected in support node in end.The present invention, while the requirement that can meet longitudinal broken line shape and the linear roof system moulding of transverse arc, decreases the quantity of connected node, increases Large Column Spacing, the stick force of upper chord is evenly distributed, materials'use economy, effectively can reduces cost.And the present invention is peculiarly shaped, graceful, has artistry, enhance the aesthetics of building.
Description
Technical field
The present invention relates to a kind of building structure roof structure, more particularly, relate to a kind of V-arrangement truss.
Background technology
Truss is a kind of form of structure of extensive use in engineering.Trussed construction form conventional in engineering has inverted triangular truss, plane frame, wherein inverted triangle truss lateral rigidity is low, two struts needing layout more between winding up, and plane frame moulding is single, when architectural image needs to form broken line moulding, these two kinds of truss are all difficult to meet the demands.
Summary of the invention
The present invention provides a kind of V-arrangement truss for solving in known technology the technical problem that exists, and this truss not only can meet the requirement of longitudinal broken line shape and the linear roof system moulding of transverse arc, can also reduce cost.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of V-arrangement truss, comprise two upper chords, a lower chord and Duo Gen web member, described web member is arranged between described upper chord and described lower chord, the two ends of described web member are respectively connected with described lower chord with described upper chord by a connected node, and the shape of cross section of this truss is V-arrangement; The axis of described upper chord is planar arc or broken line, and the axis of described lower chord is straight line or planar arc or broken line, and two described upper chords and a described lower chord are intersected in support node in end.
Described connected node adopt in cast steel node, tubular joint and welded hollow spherical joints any one; Described support node adopt in cast steel node, tubular joint and welded hollow spherical joints any one.
Described upper chord, described lower chord and described web member are round steel pipe or square steel pipe.
The advantage that the present invention has and good effect are: by adopting the structure of strut between cancellation two upper chord, while the requirement that can meet longitudinal broken line shape and the linear roof system moulding of transverse arc, decrease the quantity of connected node.Two upper chords intersect at a point respectively in two ends, only using a lower chord, increasing post distance when ensureing that upper chord quantity is constant.The outer bending moment diagram just as simply supported beam under evenly distributed load of this truss, makes the stick force of upper chord be evenly distributed, materials'use economy, effectively can reduce cost.And the present invention is peculiarly shaped, graceful, has artistry, enhance the aesthetics of building.

Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 4, a kind of V-arrangement truss, comprise two upper chords, 1, lower chord 2 and Duo Gen web member 3, described web member 3 is arranged between described upper chord 1 and described lower chord 2, the two ends of described web member 3 are respectively connected with described lower chord 2 with described upper chord 1 by a connected node 5, and the shape of cross section of this truss is V-arrangement; The axis of described upper chord 1 is planar arc or broken line, and the axis of described lower chord 2 is straight line or planar arc or broken line, and two described upper chords 1 and a described lower chord 2 are intersected in support node 4 in end.Web member 3 is arranged according to trussed construction, can only arrange vertical web rod or diagonal web member, also can arrange vertical web rod and diagonal web member simultaneously.
In the present embodiment, the axis of upper chord 1 is planar arc, the axis of lower chord 2 is straight line, web member 3 is vertical web rod, a upper chord 1 and a lower chord 2 and the bending moment diagram of figure with simply supported beam under evenly distributed load being connected vertical web rod formation between which, the stick force of upper chord is evenly distributed, and force-bearing situation is good.
Upper chord 1, lower chord 2, web member 3 can adopt round steel pipe or square steel pipe; Adopt round steel pipe in the present embodiment.Support node 4 and connected node 5 can adopt cast steel node, tubular joint or welded hollow spherical joints.Support node 4 adopts welded hollow spherical joints in the present embodiment, and connected node 5 adopts tubular joint.
In above-mentioned V-arrangement truss, all described upper chords 1, lower chord 2, web member 3 are and are welded to connect.
Above-mentioned V-arrangement truss, by the make of the upper chord of uniqueness, lower chord and web member, enhances the lateral rigidity of roof system.Eliminate the strut between two upper chords, decrease the quantity of connected node, meet the needs for architectural image in roof design preferably.Can realize roof system cross section is arc line shaped moulding, and longitudinal profile is fold-line-shaped moulding, meets roof system moulding and instructions for use.
Although be described the preferred embodiments of the present invention by reference to the accompanying drawings above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, can also make a lot of form, these all belong within protection scope of the present invention.
Claims (3)
