The design of its bent angle, the lifting mechanism inertia couple that can step forward promotes intensity.
Description
Technical field
This utility model relates generally to the technical field of cold-pressing quality steel structural shape, is specifically related to the square square Hollow H-shaped steel of a kind of band bent angle.
Background technology
I-steel is as existing steel construction section bar, it is the shaped steel of a kind of extensive application, for I-steel cross section structure research and improve also in constantly carrying out, existing improvement typically all concentrates on the adjustment of its dimensional structure, the most directly cross sectional shape and the processing technique of I-steel is not carried out subversive improved plan, so lifting to i-beam structure performance is just hesitated to move forward, and does not has the biggest lifting, and applicant feels the need to improve.
Utility model content
In order to promote solution the problems referred to above, the utility model proposes the square square Hollow H-shaped steel of a kind of band bent angle.
The technical solution of the utility model is: the square square Hollow H-shaped steel of a kind of band bent angle, it is characterized in that: it surrounds rectangular cross section by steel plate bending is hollow I-shaped cross-section, and this Hollow H-shaped steel includes outer upper flange, outer lower wing plate；Also including two openings being arranged symmetrically with interior cell body to the left and opening interior cell body to the right, this interior cell body includes interior upper flange, interior lower wing plate, endosternum；The outer edge of described interior upper flange is connected with the edge of outer upper flange；The outer edge of described interior lower wing plate is connected with the edge of outer lower wing plate, is provided with inwardly protruded bent angle in the junction of interior upper flange Yu outer upper flange；It is provided with inwardly protruded bent angle in the junction of interior lower wing plate Yu outer lower wing plate.
Described interior upper flange, interior lower wing plate, endosternum at least one be corrugated plating, its ripple fluctuation direction identical or vertical with the length direction of this Hollow H-shaped steel.
In the connection edge connecting edge or outer lower wing plate and interior lower wing plate of described outer upper flange and interior upper flange, at least surface is provided with the attachment weld of steel plate.
Four bent angles of described square square Hollow H-shaped steel are at least provided with attachment weld at one.
The ripple cross section of described corrugated plating is rectangular wave or for triangular wave or for arc-shaped wave.
Of the present utility model have the technical effect that
The square square Hollow H-shaped steel of this band bent angle, is shaped to hollow I-steel by steel plate bending, and such structure is designed to significantly promote this moment of inertia, thus promotes the bending resistance of this I-steel, torsional strength, the performance of releasable material that can be the biggest.The design of its bent angle, it is possible to further lifter the moment of inertia, promotes intensity.
Wing plate in it or endosternum are designed to antinode plate structure, it is possible to further promote the structural strength of this Hollow H-shaped steel, promote its bearing capacity.

Detailed description of the invention
Embodiment one: see Fig. 1-2, the square square Hollow H-shaped steel of a kind of band bent angle, it is characterized in that: it surrounds rectangular cross section by steel plate bending is hollow I-shaped cross-section, and this Hollow H-shaped steel includes outer upper flange, outer lower wing plate；Also including two openings being arranged symmetrically with interior cell body to the left and opening interior cell body to the right, this interior cell body includes interior upper flange, interior lower wing plate, endosternum；The outer edge of described interior upper flange is connected with the edge of outer upper flange；The outer edge of described interior lower wing plate is connected with the edge of outer lower wing plate, is provided with inwardly protruded bent angle in the junction of interior upper flange Yu outer upper flange；It is provided with inwardly protruded bent angle in the junction of interior lower wing plate Yu outer lower wing plate.
Four bent angles of described square square Hollow H-shaped steel are at least provided with attachment weld at one.
Embodiment two: see Fig. 3, embodiment two is essentially identical with embodiment one, something in common does not repeats, difference is, described upper interior upper flange in embodiment two, interior lower wing plate, endosternum are corrugated plating, and the fluctuation direction of its ripple is identical or vertical with the length direction of this Hollow H-shaped steel.The ripple cross section of described corrugated plating is rectangular wave.
Embodiment four: see Fig. 4, embodiment four is essentially identical with embodiment one, something in common does not repeats, difference is, described upper interior upper flange in embodiment four, interior lower wing plate, endosternum are corrugated plating, and the fluctuation direction of its ripple is identical or vertical with the length direction of this Hollow H-shaped steel.The ripple cross section of described corrugated plating be triangular wave,
