Hollow composite beam and manufacturing method thereof
The invention relates to a hollow composite beam and a manufacturing method thereof. The composite beam is combined with concrete on the basis of a hollow steel framework, the steel framework comprises an upper flange plate, a lower flange plate, truss angle steel or steel bars in the middle and tie bars at the inner wall edges of the upper flange plate and the lower flange plate, through structural design, a steel framework stress component forms a stress steel structure whole, and poured concrete is restrained through a cavity formed by the steel framework to form a steel-coated concrete opening component. According to the beam and the method, a stress mechanism of the composite beam is similar to that of a steel structure component, the steel structure cavity restrains the concrete, axial force can be shared by the concrete, meanwhile, a steel plate can be restrained from buckling by the concrete to form a combined effect, steel structure sections of the whole composite beam all participate in stress, and the anti-seismic performance is superior to that of a traditional concrete-clad steel composite structure. The steel framework serves as a pouring template when the concrete ispoured, the trouble of extra formwork erection is eliminated, and the advantages of low steel consumption and good bearing capacity are achieved.
本发明涉及一种空腹式组合梁及其制作方法，该组合梁基于空腹式钢骨架与混凝土结合，其中钢骨架包括上、下翼缘板、中间的桁架角钢或钢筋、以及上、下翼缘板内壁边缘的拉结筋，通过结构设计令钢骨架受力构件形成一受力钢结构整体，并通过钢骨架形成的腔体对所浇筑的混凝土进行约束，形成钢包覆混凝土的开口构件。本发明组合梁受力机理类似于钢结构构件，钢结构腔体对混凝土形成约束，使混凝土可以分担轴力，同时混凝土能约束钢板屈曲，形成组合作用，整个组合梁的钢结构截面均参与受力，抗震性能优于传统混凝土包覆钢的组合结构。本发明的钢骨架在浇筑混凝土时充当浇筑模板，省去了额外支模的麻烦，具有用钢量低、承载力好的优点。
