The invention discloses a light-weight and low-wind-load bearing main beam, relates to the technical field of hoisting bearing beams, and solves the problems that the influence of wind and equipment dead weight on the design and cost of the whole equipment is more and more prominent, and the capital construction design is influenced. Comprising an upper flange plate and a lower flange plate, two side plates are connected between the upper flange plate and the lower flange plate, one side or two sides of the upper flange plate are provided with moving rails along which equipment can move, and the thickness of the lower flange plate is smaller than that of the upper flange plate; and the section width of the lower flange plate is greater than that of the upper flange plate, so that the upper flange plate, the lower flange plate and the two side plates form a trapezoid with a large lower part and a small upper part. The cross-sectional moment of inertia of the main beam can be improved, and the effects of reducing the dead weight of the main beam and ensuring full application of the moment of inertia of the main beam are achieved.
本发明公开了一种轻量化低风载的承载主梁,涉及起重承载梁技术领域,解决了风和设备自重对整个设备的设计和成本的影响越来越突出,影响到基建设计的问题。包括上翼缘板和下翼缘板,上翼缘板和下翼缘板之间连接有两侧侧板,上翼缘板的一侧或两侧安装供其中设备沿其移动的移动轨道,下翼缘板厚度小于上翼缘板的厚度;下翼缘板的截面宽度大于上翼缘板的截面宽度,使上翼缘板、下翼缘板和两侧侧板形成下大上小的梯形。其能提高主梁的截面惯性矩,达到了使主梁自重降低,并确保主梁惯性矩充分应用的效果。
