Profile steel with cross section shaped like Chinese character 'ri'
The invention discloses profile steel with the cross section shaped like the Chinese character 'ri'. The profile steel comprises a rectangular steel pipe and U-shaped channel steel, the ends of the two free edges of the U-shaped channel steel and the two corners of the rectangular steel pipe are welded in the length direction of the rectangular steel pipe to form side welding lines, and the crosssection of the profile steel composed of the rectangular steel pipe and the U-shaped channel steel is shaped like the Chinese character 'ri'. Compared with the prior art, the profile steel with the cross section shaped like the Chinese character 'ri' is few in welding position and convenient to weld, the strength and the application range of the profile steel can be improved, the bending resistance is isotropic, the bending resistance of steel is enhanced, the inertia moment of a component is improved, the cross section of the component can be reduced under the same design strength requirement, the indoor use area of a building is increased, the strength of components with the same section is improved, and the steel cost is reduced.
本发明公开了一种日字型截面型钢，包括矩形钢管和U型槽钢，所述U型槽钢的两个自由边的端部与矩形钢管的两个角沿着矩形钢管长度方向焊接形成侧部焊接线，所述矩形钢管和U型槽钢组成的型钢的横截面呈日字型。与现有技术相比，本发明的日字型截面型钢焊接位置少，而且焊接方便，能够增加型钢的强度和使用范围，其抗弯性能各向同性，增强了钢材的抗弯性能，提高了构件的惯性矩，在相同设计强度要求下，能减小构件截面，增加建筑室内使用面积的作用，增加相同截面构件强度，并减少钢材成本。
