(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a flange side support of a steel frame beam with unequal heights comprises a section steel column, wherein a large H-shaped steel beam and a small H-shaped steel beam are arranged on the section steel column respectively, an upper flange side angle steel support and a lower flange side angle steel support are welded on the small H-shaped steel beam, one ends, far away from the small H-shaped steel beam, of the upper flange side angle steel support and the lower flange side angle steel support are welded on the large H-shaped steel beam, a steel frame beam vertical stiffening rib with a smaller cross section is welded on the small H-shaped steel beam, the steel frame beam vertical stiffening rib with the smaller cross section is welded with the left sides of the upper flange side angle steel support and the lower flange side angle steel support, a steel frame beam vertical stiffening rib with a higher cross section is welded on the large H-shaped steel beam, and the steel frame beam vertical stiffening rib with the upper flange side angle steel support and the right side of the lower flange side angle steel support are welded on the upper flange side stiffening rib;
the plane of the vertical stiffening rib of the steel frame beam with the smaller section and the plane of the small H-shaped steel beam form an included angle of 45 degrees, and the plane of the vertical stiffening rib of the steel frame beam with the higher section and the plane of the large H-shaped steel beam form an included angle of 45 degrees;
the plane of the upper flange lateral angle iron support and the plane of the lower flange lateral angle iron support are parallel to each other.
(III) advantageous effects
The utility model provides a side support for flanges of unequal-height steel frame beams. The method has the following beneficial effects:
this unequal-height steel frame beam flange side direction support utilizes and adds the vertical stiffening rib of putting to one side at the roof beam tip, with the steel frame beam flange indirect connection of two directions of beam column node, provides the side direction support mutually, improves the out-of-plane stability when the beam-ends atress. The principle does wherein, utilizes the vertical stiffening rib of putting to one side and the angle iron support of putting to one side, makes the steel framework roof beam bottom wing edge that is not at the coplanar realize the purpose of indirect connection, and the top wing edge of same roof beam also adopts the angle steel to realize connecting, and not only installation construction is convenient, and long-term use maintenance cost is lower moreover to guarantee the stability outside the beam-ends plane during the building use and when seismic action, and this steel framework roof beam edge of a wing lateral support can realize mill's mass production.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. vertical stiffening ribs of the steel frame beam with the smaller cross section; 2. vertical stiffening ribs of the steel frame beam with the higher section; 3. the lower flange is supported by lateral angle steel; 4. the upper flange is supported by lateral angle iron.
Detailed Description
