Profile steel partially-wrapped concrete composite beam and design and construction method thereof
The invention discloses a profile steel partially-wrapped concrete composite beam and a design and construction method thereof. The profile steel partially-wrapped concrete composite beam comprises an H-shaped steel beam and concrete partially wrapping an H-shaped steel beam, wherein the H-shaped steel beam comprises a steel beam web and two steel beam flanges vertically arranged on the two sides of the steel beam web, and the profile steel partially-wrapped concrete composite beam further comprises fire-resistant rock wool boards arranged on the two sides of the steel beam web and located between the two steel beam flanges; the height of the fire-resistant rock wool boards is smaller than the distance between the two steel beam flanges, and the width of the fire-resistant rock wool boards is smaller than half of the difference between the width of the steel beam flanges and the width of the steel beam web. Through reasonable arrangement of component structures, the problems that an existing large-span beam is heavy in mass and has initial deflection in a span are solved while the bearing capacity and rigidity of the composite beam are not reduced too much, the construction cost is reduced, and the composite beam can be applied to high-rise large-span steel structure buildings.
一种型钢部分包裹混凝土组合梁及其设计与施工方法，包括H型钢梁和部分包裹H型钢梁的混凝土，H型钢梁包括钢梁腹板和垂直设在钢梁腹板两边的两个钢梁翼缘，还包括设在所述钢梁腹板两侧、且位于两个钢梁翼缘之间的抗火岩棉板，抗火岩棉板的高度小于两个钢梁翼缘之间的距离，抗火岩棉板的宽度小于钢梁翼缘宽度与钢梁腹板宽度差的一半。通过对部件结构的合理设置，在不过多降低组合梁承载力及刚度的同时，解决现大跨梁中质量偏重，跨中存在初始挠度的问题，降低工程造价，可应用于高层大跨的钢结构建筑物中。
