Abstract
The invention relates to a closed combination section of a hollow flange of a cold-bend thin-wall steel member. The closed combination section is characterized in that: the closed combination section is formed by connecting two single-limb hollow flanges; the section of each single-limb hollow flange is a hollow polygonal closed section; and the two single-limb hollow flanges are connected to form the closed combination section of the hollow flange of the cold-bend thin-wall steel member. In the range of section parameters of the single-limb hollow flange, the relative height hS/h of a flange section closed area is equal to 1/6 and 1/2, wherein h is the height of the section of the cold-bend thin-wall steel member, and hS is the height of the flange section closed area. The closed combination section is high in bearing capacity and ductility, full in stiffening and difficult to deform locally, and is suitable for bearing the action of axial compression, bending moment and bending loads.
Description
Technical field: the present invention relates to a kind of light gauge cold-formed steel shape member, specifically is a kind of light gauge cold-formed steel shape member hollow wing edge compound section.
Background technology: the light gauge cold-formed steel shape member has cross section moulding flexible characteristic, can obtain higher bearing capacity by the flakiness ratio of control steel member section composition plate, thereby reach the purpose that makes full use of material.Existing light gauge cold-formed steel shape cross section is clod wash hollow wing edge beam section HFB, 1993, Australia at first proposes and has produced in batches a kind of light gauge cold-formed steel shape member hollow wing edge beam HFB (Hollow Flange Beam), and its cross section characteristics are to make its two edge of a wing form closed triangle by welding after the clod wash.HFB is processed by the cold forming of light gauge cold-formed steel shape veneer, and forms the closed edge of a wing with resistance welding technology, and hollow wing edge beam is able to extensive use with higher torsional rigidity and processing and manufacturing process economically and reasonably.But, hollow wing edge beam HFB cross section two triangle hollow wing edge height accounts for overall depth of section, and generally to be no more than 1/6, two hollow wing edge part more flat, and cross section two equatorial moment of inertias differ comparatively great disparity, so generally be unfavorable for bearing shaft pressuring load and press-bending load, its member used be restricted.
Summary of the invention: the purpose of this invention is to provide a kind of being beneficial to and bear shaft pressuring load and press-bending load, the closed compound section of light gauge cold-formed steel shape member hollow wing edge that supporting capacity is strong.Technical scheme of the present invention is: the present invention includes light gauge cold-formed steel shape member hollow wing edge, it is characterized in that the hollow wing edge is to be connected to form by two single limb hollow wing edge, each single limb hollow wing edge cross section is a hollow polygon closed section, two single limb hollow wing edge cross sections link together and constitute the closed compound section of light gauge cold-formed steel shape member hollow wing edge, and single limb hollow wing edge cross section parameter scope is: cross section, edge of a wing closed area relative altitude h
S/ h=1/6～1/2; h
a/ h=0～1/3, wherein h is light gauge cold-formed steel shape member section height, h
SBe hollow wing edge cross section closed area height, h
aBe polygon hollow wing edge closed section vertical edges height.
The present invention is controlled at 1/6～1/2 with the ratio that closed section height partly in single limb edge of a wing accounts for overall depth of section, cross section, the closed edge of a wing of single limb can be the polygon closed section, form edge of a wing welding polygon closed section, make putting more energy into of composition plate more abundant, carry out more in the cross section, also can elect cross section, the closed edge of a wing of single limb as the triangular closed cross section, increase, differ the comparatively problem of great disparity so solved cross section two equatorial moment of inertias because the height in triangular closed cross section accounts for overall depth of section proportion.By theory analysis as can be known, hollow wing edge closed section member of the present invention has performance advantages such as supporting capacity is strong, ductility good, put more energy in the cross section fully, the difficult generation of local distortion, is suitable for bearing axial compression, moment of flexure and press-bending load action.
