Asymmetric flange H-shaped steel-concrete composite beam and formwork-free construction method thereof
The invention provides an asymmetric flange H-shaped steel-concrete composite beam and a formwork-free construction method thereof, and belongs to the technical field of buildings. Comprising asymmetric flange H-shaped steel, concrete and steel screens, the asymmetric flange H-shaped steel is located in the concrete, a steel member is further arranged in the concrete, and the two sides of the concrete and the outer side of the asymmetric flange H-shaped steel are wrapped by the steel screens. According to the device, local buckling generated when the upper flange steel plate is pressed can be prevented through concrete wrapping, the tension effect of the lower flange steel plate is brought into full play, and the economical efficiency is improved; the two sides of the beam are provided with the steel plate net formworks, additional formwork erecting is not needed, manpower can be saved, and meanwhile the steel plate net can prevent the painting layer from cracking and falling off.
本申请提供一种非对称翼缘H型钢‑混凝土组合梁及其免支模构造方法，属于建筑技术领域。包括非对称翼缘H型钢、混凝土和钢板网，非对称翼缘H型钢位于混凝土内，所述混凝土内还设置有钢构件，混凝土两侧以及非对称翼缘H型钢的外侧均以钢板网包裹。本装置通过混凝土包裹可防止上翼缘钢板受压时产生局部屈曲，且充分发挥下翼缘钢板受拉作用，提高了经济性；梁两侧自带钢板网模板，无需另外支模，可节省人力，同时钢板网可防止粉刷层的开裂脱落。
