Abstract
The invention provides I steel. The I steel comprises a top part, a rib part and a bottom part, wherein the rib part is vertically connected with the top part and the bottom part to form an I-shaped steel material, the rib part has two sides, and at least one side of the rib part comprises a reinforcement part. The rib part is additionally provided with the reinforcement part, so that the strength of the I steel is high, the structure is strong, the stability is high, and the I steel is suitable for more engineering.
Description
Technical field
The present invention relates to steel field, relate in particular to a kind of i iron.
Background technology
I iron also claims girder steel, is that cross section is I-shaped rectangular steel.Its specification represents with the milli number of waist wide (the b) * waist of high (h) * leg thick (d), as " work 160 * 88 * 6 ", represents that waist high is 160 millimeters, and leg is wide is 88 millimeters, and waist is thick is the i iron of 6 millimeters.The specification of i iron also available model represents, model represents the cms that waist is high, as work 16#.The high identical i iron of waist, wide and waist is thick if any several different legs, need add a, b on model the right and c is distinguished, as 32a#, 32b# and 32c# etc.I iron divides common i iron and i iron, and the specification of the common i iron of hot rolling is 10#-63#.The common i iron specification of hot rolling through the supply of both sides of supply and demand agreement is 12#-55#.I iron is widely used in various building structure, bridge, vehicle, support, machinery etc.No matter existing i shaped steel is plain edition or light-duty because sectional dimension is all relatively high, narrower therefore the moment of inertia of two main sleeves of pair cross-section differs larger.Therefore, generally only can be used directly in and in its web plane, be subject to curved member or formed lattice primary structure member.To axis compression member or also having crooked member all should not adopt perpendicular to web plane, this just makes it in range of application, have great limitation.
Summary of the invention
In view of this, the invention provides a kind of i iron and comprise top part, flank and bottom surface sections, the vertical steel that connect described top part and described bottom surface sections formation I shape of described flank, described flank has both sides, and one of them side includes rib.
The present invention is further preferred, and described rib is arc.
The present invention is further preferred, and described arc rib invests a side of whole flank.
The present invention is further preferred, and the centre position of described arc rib thick and described flank is positioned at same level height.
The present invention is further preferred, and described rib is triangle.
The present invention is further preferred, and described triangle rib invests the both sides of part flank.
The present invention is further preferred, and the centre position of described triangle rib thick and described flank is positioned at same level height.
The present invention is further preferred, and described top part and described bottom surface sections include chamfering.
Compared with prior art, i iron provided by the present invention, owing to having increased rib at flank, makes the intensity of i iron higher, and structure is stronger, and stability improves, and is applicable to more engineering.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention one i iron;
Fig. 2 is the schematic diagram of the embodiment of the present invention two i iron.
The specific embodiment
Below with reference to accompanying drawings the present invention is carried out to recapitulative description, wherein show more of the present invention rather than whole embodiment.Certainly, these embodiment can be embodied in many different forms, and are not appreciated that and only limit to the embodiments set forth herein; But, provide these embodiment, thereby the disclosure will meet enforceable legal requirement.
Embodiment mono-
Please refer to Fig. 1, the i iron 1 that the embodiment of the present invention one provides comprises top part 11, flank 12 and bottom surface sections 13, the vertical steel that connect described top part 11 and described bottom surface sections 13 formation I shapes of described flank 12, and described flank 12 has both sides, is respectively.In the present invention, one of them side includes rib, and in the present embodiment, concrete, described rib is arc, and invests a side of whole flank 12.The part that arc conduct is circular, its thickness increases to middle part gradually from two tips, thereby the centre position of described arc rib 121 thicks and described flank 12 is positioned at same level height.For i iron 1, its comparatively fragile part is described flank 12, and the present embodiment, can be so that the reinforcement of the intensity of flank 12 by increasing arc rib 121 at flank 12.And the centre position of described flank 12 is parts the most fragile in whole flank 12, and because the thickest part of the arc rib 121 of the present embodiment is positioned at same level height with the centre position of described flank 12, thereby can carry out maximum booster action to the part of i iron 1 most fragile, make i iron 1 intensity higher, structure is stronger, stability improves, and is applicable to more engineering.
It should be noted that, in the i iron 1 of the present embodiment, described top part 11 and described bottom surface sections 13 include chamfering, and described chamfering is for coordinating with other workpiece.In addition, at the vertical width that connects the local flank 12 of described top part 11 and described bottom surface sections 13 of described flank 12, there is increase, form the foot connecting.
Embodiment bis-
Please refer to Fig. 2, the i iron 1 that the present embodiment provides is most of identical with the i iron of embodiment mono-1, difference is, rib described in the present embodiment is triangle, for 122 in Fig. 2 and 123 and described triangle rib 122 and 123 invest the both sides of flank 12.And in the present embodiment, the flank that invest whole side 12 of triangle rib 122 and 123 unlike in embodiment, but only invest the stage casing part of flank 12.Be similar to the arc rib 121 in embodiment, described triangle rib 122 in the present embodiment and the centre position of 123 thicks and described flank 12 are positioned at same level height, same, can play like this effect of strengthening i shaped steel most fragile part.
Although the present invention with preferred embodiment openly as above; but it is not for limiting the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that the claims in the present invention were defined.
