Abstract

The utility model provides bended web welding I-steel, which comprises a web, an upper flange and a lower flange, wherein, the two flanges are respectively welded with the upper and the lower parallel edges of the web. The web is a longitudinal bended web whose plate body is convex-concave interphase to form a convex edge and a flute which are evenly perpendicular to the flanges, and the convex edge of the front surface of the longitudinal bended web is corresponding to the identical regional back surface which namely is the flute, vice versa. The formed convex edge and the flute are evenly perpendicular to the flanges. The web whose plate body is convex-concave interphase can be made of planar metal sheet materials through cold rolling or hot rolling. Because the web of the traditional welding I-steel is reconstructed by the utility model, the anti-shearing bearing ability of the web is efficiently enhanced, and the integral load intensity of the welding I-steel is greatly enhanced. Meanwhile, cross braces used for enhancing the anti-shearing instability intensity of the web in the use of the traditional welding I-steel are also saved, and thus materials are saved and welding amount of work is reduced.

Description

Bent body web welding H-bar

Technical field

The utility model relates to a kind of welding H-bar, is specially bent body web welding H-bar.

Background technique

At present, the structure of welding H-bar comprises web, and with two edges of a wing up and down that two parallel edges about the web weld respectively, the web and two edges of a wing are perpendicular; Because two surfaces were all the planar metal sheet material on plane before and after web wherein was, in the higher occasion of some loads, this web is because anti-shearing bearing capacity is lower, so just very likely produce unstable failure, perhaps make total bigger distortion even permanent deformation take place around the member axis direction.And in order to have improved the anti-shearing bearing capacity of web, perhaps make the bigger loading intensity of the whole acquisition of welding H-bar, generally the method for Cai Yonging is the size that increases section, perhaps adopts the additional floor perpendicular to the edge of a wing that web is cut apart, thereby increases the anti-shearing unstability intensity of web; Also have plenty of the higher material of working strength and make I-steel, yet these two kinds of means all can increase the cost of total unit length or manufacturing process that need be special, so expensive consumptive material.

Summary of the invention

In order to improve the loading intensity of welding H-bar under the situation that does not increase material, or obtain the identical loading intensity of welding H-bar made with the more material of use with less material, the utility model provides a kind of bent body web welding H-bar.

Technological scheme described in the utility model is as follows: a kind of bent body web welding H-bar comprises web, with web two parallel edges, two edges of a wing up and down of welding respectively up and down; Web is a vertical bent body web; Described vertical bent body web is meant: be all the comparing of planar webs on plane with two surfaces, existing front and back, the plate body convex-concave of this web is alternate, and the fin of front surface is groove corresponding to the rear surface of same area, vice versa, and the fin that forms and groove are all perpendicular to the edge of a wing.So-called bent body just is being meant that the plate body convex-concave of web is alternate.The alternate web of this plate body convex-concave can be made through cold rolling or hot rolling with planar metal sheet material.

The utility model is by transforming the web of traditional welding I-steel, not only improved the anti-shearing bearing capacity of web effectively, and improved the whole loading intensity of welding H-bar widely, also saved the floor that uses for the anti-shearing unstability intensity that improves web during the traditional welding I-steel uses simultaneously, thereby saved material, reduced the welding job amount.

Embodiment

A kind of bent body web welding H-bar comprises web 1, with web two parallel edges, two edges of a wing 2 up and down of welding respectively up and down; Web be the alternate and fin that forms of a plate body convex-concave and groove all perpendicular to the vertical bent body web on the edge of a wing, the fin of its front surface is groove corresponding to the rear surface of same area, vice versa.

Embodiment 1: with planar metal sheet material as web, weld with the edge of a wing, again web is handled through existing cold-rolling process, make above-mentioned vertical bent body web, fin and groove the past, the rear surface of formation are seen, be all consecutive intervals, and be positioned at the middle part of web plate body, and the weld apart from the web and the edge of a wing has certain distance, and also promptly near two surfaces of the web the weld on the web and the edge of a wing still are the planes.So just be made into above-mentioned bent body web welding H-bar.

Embodiment 2: with planar metal sheet material as web, weld with the edge of a wing, again web is handled through existing hot rolling technology, make above-mentioned vertical bent body web, fin and groove the past, the rear surface of formation are seen, be all consecutive intervals, and be positioned at the middle part of web plate body, and the weld apart from the web and the edge of a wing has certain distance, and also promptly near two surfaces of the web the weld on the web and the edge of a wing still are the planes.So just be made into above-mentioned bent body web welding H-bar.

Embodiment 3: will handle through existing hot rolling technology as the planar metal sheet material of web, make above-mentioned vertical bent body web, fin and groove the past, the rear surface of formation are seen, be all consecutive intervals, and run through whole web, again should vertical bent body web and edge of a wing welding, promptly made above-mentioned bent body web welding H-bar.In this case, the welding line on the web and the edge of a wing is a curve.

Embodiment 4: will handle through existing cold-rolling process as the planar metal sheet material of web, make above-mentioned vertical bent body web, fin and groove the past, the rear surface of formation are seen, be all consecutive intervals, and run through whole web, again should vertical bent body web and edge of a wing welding, promptly made above-mentioned bent body web welding H-bar.In this case, the welding line on the web and the edge of a wing is a curve.

Embodiment 5: with planar metal sheet material as web, weld with the edge of a wing, again web is handled through existing cold-rolling process, make above-mentioned vertical bent body web, the fin of formation and groove the past, rear surface are seen, be discontinuous interval, be still to be planar metal sheet material between fin and the groove, and be positioned at the middle part of web plate body, and certain distance is arranged apart from the weld on the web and the edge of a wing, also promptly near two surfaces of the web the weld on the web and the edge of a wing still are the planes.So just be made into above-mentioned bent body web welding H-bar.

Embodiment 6: will handle through existing cold-rolling process as the planar metal sheet material of web, make above-mentioned vertical bent body web, fin and groove the past, the rear surface of formation are seen, be discontinuous interval, be still to be planar metal sheet material between fin and the groove, and run through whole web, and again should vertical bent body web and edge of a wing welding, promptly made above-mentioned bent body web welding H-bar.In this case, the welding line on the web and the edge of a wing is a curve.
