Abstract
The utility model belongs to the steel structural component field especially relates to a bearing steel beam, including girder steel main part and mounting panel, the welding of the one end of girder steel main part is at the center of mounting panel, and the splice is provided with the triangle -shaped gusset, and the girder steel main part includes and inner tube and outer tube are provided with the heliciform gusset between inner tube and the outer tube that inner tube, outer tube and heliciform gusset three are the whole of a no seam. The utility model discloses the steel pipe has been made the bilayer structure who constitutes by inner tube and outer tube to set up the heliciform gusset the bilayer structure in the middle of, the torsional strength increase that can make the steel pipe doubly, thereby expanded the range of application of steel pipe, set up the triangle -shaped gusset on the diagonal of square mounting panel, guaranteed the joint strength between girder steel main part and the mounting panel, also strengthened the anti surrender ability of girder steel main part root simultaneously, the rational arrangement of of mounting hole quantity and position has guaranteed the fastness of installing, also can effectively prevent that the mounting panel atress warp simultaneously under the certain condition of mounting panel thickness.
Description
Technical field
The utility model belongs to steel construction piece field, particularly relates to a kind of load-bearing girder steel.
Background technology
Round steel pipe is a kind of structural member conventional in building, more saves the feature of material compared with the steel pipe of other cross sectional shape under having larger, the identical behavior in service of flexural strength.But the torsional strength of common steel tube is poor, this shortcoming greatly limit the range of application of round steel pipe in steel work.
Summary of the invention
The utility model provides a kind of load-bearing girder steel, to make full use of the advantage of steel pipe and to solve the problem of the common steel tube torsional strength difference proposed in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of load-bearing girder steel, comprise girder steel main body and installing plate, one end of girder steel main body is welded on the center of installing plate, weld is provided with triangle gusset, girder steel main body comprises inner and outer tubes, be provided with helical form gusset between inner and outer tubes, interior pipe, outer tube and helical form gusset three are a jointless entirety.
Described installing plate is square structure, and described triangle gusset has four pieces, is all arranged on foursquare diagonal, the installing plate between two pieces of triangle gussets is respectively provided with two installing holes, and the line of two installing holes is parallel with square sideline.
Described helical form gusset has two at least, and each bar helical form gusset is uniform relative to the circumference of girder steel main body.
The pitch of described helical form gusset and the ratio range of outer tube diameter are 10 ~ 30.
The beneficial effects of the utility model are:
1, the double-decker be made up of inner and outer tubes made by steel pipe by the utility model, and is provided with helical form gusset in the middle of double-decker, the torsional strength of steel pipe can be made to increase several times, thus extend the range of application of steel pipe;
2, triangle gusset is arranged on the diagonal of square mounting plates, ensure that the bonding strength between girder steel main body and installing plate, also enhance the anti-surrender ability of girder steel body heel simultaneously;
3, the reasonable Arrangement of installing hole quantity and position, effectively ensure that the fastness of installation, also can effectively prevent installing plate stress deformation when installing plate thickness is certain simultaneously;
4, the pitch of helical form gusset and the ratio of outer tube diameter are arranged between 10 ~ 30, both ensure that the hot-extrudable technique realizability adding man-hour of girder steel main body, in turn ensure that the object optimizing torsional strength fully realizes.
