Profile steel with cross section shaped like Chinese character 'tian'
The invention discloses profile steel with the cross section shaped like the Chinese character 'tian'. The profile steel comprises two rectangular steel pipes and two pieces of angle steel, the two rectangular steel pipes are arranged diagonally, the middle contact positions of the two rectangular steel pipes are welded in the length direction of the rectangular steel pipes to form middle weldinglines, the two pieces of angle steel are arranged diagonally, the ends of the two free edges of the angle steel are welded to the side lines of the two adjacent rectangular steel pipes in the length direction of the rectangular steel pipes to form edge welding lines, and the cross section of the profile steel composed of the two rectangular steel pipes and the two pieces of angle steel is shaped like the Chinese character 'tian'. Compared with the prior art, the profile steel with the cross section shaped like the Chinese character 'tian' is few in welding position and convenient to weld, thestrength 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.
本发明公开了一种田字型截面型钢，包括两个矩形钢管，还包括两个角钢，两个所述矩形钢管对角布置，两个矩形钢管的中间接触位置沿着矩形钢管长度方向焊接形成中间焊接线，两个角钢对角布置，角钢的两个自由边的端部分别与相邻的两个矩形钢管的边线沿着矩形钢管长度方向焊接形成边部焊接线，两个矩形钢管和两个角钢组成的型钢的横截面呈田字型。与现有技术相比，本发明的田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。
