Abstract
The invention relates to a closed section for a hollow flange of a cold-bend thin-wall steel member. The closed section comprises a flange of the cold-bend thin-wall steel member, and is characterized in that: the section of the flange of the cold-bend thin-wall steel member is a hollow polygonal closed section, and in the range of section parameters, the relative width bS/b of a flange section closed area is equal to 0 and 1/2, and the relative height hS/h of the 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, b is the width of the bottom edge of the flange section, hS is the height of the flange section closed area, and bS is the width of the closed area from the flange section edge to a webplate. The closed section is high in bearing capacity, full in stiffening and difficult to deform locally, and is suitable for bearing the action of bending moment, axial compression 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 cross 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 closed edge of a wing beam 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, a kind of light gauge cold-formed steel shape member hollow wing edge closed section 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 light gauge cold-formed steel shape member hollow wing edge cross section is a hollow polygon closed section, the cross section parameter scope is: hollow wing edge cross section closed area relative width b
S/ b=0～1/2, hollow wing edge cross section closed area relative altitude h
S/ h=1/6～1/2; Wherein h is a light gauge cold-formed steel shape member section height, and b is a hollow wing edge breadth of section, h
SBe hollow wing edge cross section closed area height, b
SBe the closed area width of section edges to web.
The present invention partly is transformed into the closed hollow wing edge of polygon with triangular closed hollow wing edge, (Hollow Flange Section-2), the ratio that HF2 hollow wing edge part highly accounts for overall depth of section is controlled at 1/6～1/2, make putting more energy into of composition plate more abundant, carry out more in the cross section, or the height of triangular closed hollow wing edge intermediate cam shape is accounted for overall depth of section proportion increase, form hollow wing edge welding triangular closed cross section HF1 (Hollow Flange Section-1), the ratio that HF1 hollow edge of a wing part height accounts for overall depth of section is controlled at 1/6～1/2; 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.
Description of drawings: Fig. 1 is the specific embodiment of the invention 1 structural representation
Fig. 2 is the specific embodiment of the invention 2 structural representations
The specific embodiment 1: the polygonal cross-section of present embodiment is a hollow pentagon closed section, the present invention includes light gauge cold-formed steel shape member hollow wing edge 1, light gauge cold-formed steel shape member hollow wing edge cross section is that two base angles are the hollow pentagon closed section at right angle, and the cross section parameter scope is: hollow wing edge cross section closed area relative width b
S/ b=1/2, hollow wing edge cross section closed area relative altitude h
S/ h=1/3; Wherein h is a light gauge cold-formed steel shape member section height, and b is a hollow wing edge breadth of section, h
