Abstract
The invention relates to a truss system used for a cold-formed thin-walled steel structure. The truss system comprises a truss chord member and a truss web member and further comprises a ridge node plate, wherein the ridge node plate is respectively connected with the truss chord member and the truss web member. Compared with the prior art, the truss system has the advantages of being capable of improving truss system node rigidity and strength and the like.
Description
Technical field
The present invention relates to a kind of trussing, especially relate to a kind of trussing for cold bending thin wall steel work.
Background technology
Under load action, truss member mainly bears axial tension or pressure, thereby can make full use of the intensity of material, in the time that span is larger, comparable solid web girder is saved material, alleviate deadweight and increase rigidity, therefore be applicable to compared with the load-carrying members of large span and tall and slender structure, as roof truss, bridge, power transmission line column, satellite launching tower, hydraulic gate, gantry etc.
Be used for traditional girder system of cold bending thin wall steel building roofing as shown in Figure 1, trussing is directly fixed chord member of truss 2 and truss web 3 with location structure bolt 1 conventionally at ridge place.This connected mode makes force localization in the end of chord member, due to rod member thinner thickness, node rigidity a little less than, under Concentrated load, easily there is local compression buckling failure in this place.
Summary of the invention
Object of the present invention is exactly to provide a kind of trussing for cold bending thin wall steel work that improves trussing Nodes Rigidity and strength in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
For a trussing for cold bending thin wall steel work, comprise chord member of truss and truss web, also comprise ridge node plate, described chord member of truss is connected by this ridge node plate with truss web.
Described ridge node plate comprises upper flat plate and lower hem, and upper flat plate is an angle of 90 degrees with lower hem and is connected.
Described upper flat plate is provided with upper flat plate perforate.
Described chord member of truss is provided with two, after the end of two chord member of truss connects by location structure bolt, then is connected with ridge node plate by upper flat plate perforate.
Described chord member of truss is fixed on the upper flat plate of ridge node plate by self-drilling screw.
Described self-drilling screw is provided with 2～6.
Described truss web is bolted on the upper flat plate of ridge node plate by location structure.
Compared with prior art, the present invention, by chord member and the web member of the fixing truss of ridge node plate, has increased the lifting surface area of Nodes, has improved the Rigidity and strength of Nodes, and the ability of trussing Nodes opposing external force and distortion strengthens.
Brief description of the drawings
Fig. 1 is the structural representation of traditional girder system;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the structural representation of ridge node plate of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 2, a kind of trussing for cold bending thin wall steel work, comprises chord member of truss 2, truss web 3 and ridge node plate 5, and described chord member of truss 2 is connected by this ridge node plate 5 with truss web 3.
As shown in Figure 3, ridge node plate 5 comprises upper flat plate 51 and lower hem 52, and upper flat plate 51 is an angle of 90 degrees with lower hem 52 and is connected.Described upper flat plate 51 is provided with upper flat plate perforate 53.
Described chord member of truss 2 is provided with two, after the end of two chord member of truss 2 connects by location structure bolt 1, then is connected with ridge node plate 5 by upper flat plate perforate 53.Described chord member of truss 2 is fixed on the upper flat plate 51 of ridge node plate 5 by self-drilling screw 4.Self-drilling screw can arrange 2～6 as required, and the present embodiment adopts 4 self-drilling screws.Described truss web 3 is fixed on the upper flat plate 51 of ridge node plate 5 by location structure bolt 1.
Compared with chord member and the web member of directly fixing truss with location structure bolt, employing ridge node plate can increase the lifting surface area of Nodes, has improved the Rigidity and strength of Nodes, and the ability of panel point place opposing external force and distortion strengthens.
