Abstract
The utility model provides an improved light U-steel whose cross-section forms a star shape and web width far exceed the width of two pleurals. An inner protruding barcode flange is milled by rolling on the back face of the web, and the even number path barcode flange is a slant set and any each neighbour barcode flange is contrary slant, a continuous triangle tooth form is composed according to the length direction of the light U-steel, but the end of each other has a separation distance to enhance substantially bulk strength, and cause the mechanical properties of flexural resistance, tensile character, and anti-fold character more superior.
Description
The utility model relates to a kind of light weight lip channel-section steel, especially a kind of web system at light weight lip channel-section steel of finger is established several oblique outstanding strip flange, and according to the triangular tooth that the length aspect the forms continuous fluctuating configuration that distributes, with the raising bulk strength, and then increase flex resistance, the anti-improved light weight lip channel-section steel of opening mechanical propertys such as property and fold resistance.
General light weight lip channel-section steel is mainly used in the skeleton of making unrestrained building material plates, and on other structural steelframes.The design of this light weight lip channel-section steel must be considered fundamentals such as weight, cost, intensity and application property, but can't take into account fully usually, and is wherein least desirable with the intensity item especially.See also Fig. 1: the stereogram of commonly using light weight lip channel-section steel.This section of commonly using light weight lip channel-section steel is
Shape is a maximum with the width of web.See also Fig. 2: the stereogram of commonly using light weight lip channel-section steel deformation state.When commonly using light weight lip channel-section steel and be applied to unrestrained building material plates skeleton or structural steel, because web intensity own there is no special reinforcement, easily overweight and dash forward external force influence because of institute's weighing load, and generation web buckling phenomenon, the Security of heavy damage integral skeleton structure, substituted if change, then very labor intensive, material resources, time again, but in addition not there is good plan again.
The purpose of this utility model is to provide a kind of improved light weight lip channel-section steel, it mainly establishes the web system of light weight lip channel-section steel the adjacent oblique outstanding strip flange in even number road, and according to the triangular tooth that the length aspect the forms continuous fluctuating configuration that distributes, to improve bulk strength, increase mechanical propertys such as flex resistance, anti-opening property and fold resistance, and then take into account fundamentals such as weight, cost, intensity and application property.
The purpose of this utility model reaches as follows:
A kind of improved light weight lip channel-section steel, it is a strip, its transverse section then is
Shape, wherein the wideest with the width of web, form the recessed strip chase in even number road at the web back side, correspondingly the web another side presents outstanding relatively strip flange, this even number road strip flange is all oblique setting, and any two strip flanges adjacent one another are all are opposite oblique, and its length direction along light weight lip channel-section steel constitutes the triangular tooth that rises and falls continuously configuration that distributes, the spacing but adjacent strip flange end each other all is separated by.
Advantage of the present utility model is: the web of improved light weight lip channel-section steel of the present utility model has strip chase and the strip flange that rises and falls and distribute and dispose continuously along its length, no matter therefore in the vertical or horizontal strip flange that all has, light weight lip channel-section steel intensity can be increased substantially, obtain better bending resistance, resist mechanical propertys such as opening, resist folding, and needn't increase raw material thickness and weight.
When making light weight lip channel-section steel, can carry out roller system strip chase and strip flange with the automated machine processing mode simultaneously, so the cost of labor that it increased is very limited.
Illustrated simple declaration:
Fig. 1 is a stereogram of commonly using light weight lip channel-section steel.
Fig. 2 is a stereogram of commonly using light weight lip channel-section steel deformation state.
Fig. 3 is the stereogram of the improved light weight lip of the utility model embodiment channel-section steel.
Fig. 4 is the stereogram of the improved light weight lip of the utility model embodiment channel-section steel web and strip flange.
The utility model will be further described as follows in conjunction with the accompanying drawings: at first, see also Fig. 3 and Fig. 4, the improved light weight lip channel-section steel 1 of present embodiment is mainly used in aspects such as unrestrained building material plates skeleton and structural steel, and the section of this light weight lip channel-section steel 1 is
Shape, wherein the width with web 2 is a maximum, the labial lamina that surpasses far away, side plate, adopt running roller to carry out rolling at web 3 dorsal parts, make the even number road toward the strip chase 3 that is recessed, then the another side opposite position promptly is outstanding strip flange 4, this even number road strip flange 4 is all oblique setting, but any two strip flanges 4 adjacent one another are all are opposite oblique, make its length direction constitute the triangular tooth distribution that rises and falls continuously and dispose, but adjacent strip flange 4 end does not each other join along light weight lip channel-section steel 1, but the spacing of being separated by, via this roller manufacturing mode, light weight lip channel-section steel 1 intensity is increased substantially.
Claims (1)
1, a kind of improved light weight lip channel-section steel, it is a strip, its transverse section then is
