Double-steel-plate reinforced concrete composite beam
The invention discloses a double-steel-plate reinforced concrete composite beam. The double-steel-plate reinforced concrete composite beam comprises an upper steel plate and a lower steel plate, the upper steel plate and the lower steel plate are symmetrically arranged, arc-shaped protruding strips are arranged on the opposite sides of the upper steel plate and the lower steel plate in the extending length direction, and shear-resistant rib units are evenly welded between the upper steel plate and the lower steel plate in the length direction of the upper steel plate and the lower steel plate.According to the double-steel-plate reinforced concrete composite beam, shear-resistant rib single bodies I and shear-resistant rib single bodies II are respectively formed by welding the four arc-shaped steel bars end to end, and the two arc-shaped steel bars on the opposite sides of each shear-resistant rib single body I and the corresponding shear-resistant rib single body II are arranged in acrossed manner, so that the space bearing area of the shear-resistant rib single bodies I and the shear-resistant rib single bodies II between the upper steel plate and the lower steel plate is increased, and the compression resistance and bending moment resisting performance are improved. In addition, due to the fact that the arc-shaped steel bars on the adjacent sides of the first shear-resistant rib single bodies and the second shear-resistant rib single bodies are in a V shape, when the beam is pressed, the arc-shaped steel bars on the side edges of the adjacent shear-resistant rib unitsabut against each other, force can be decomposed to the radial direction of the whole beam, and the compression resistance and bending moment resistance of the beam are further improved.
本发明公开了一种双钢板钢筋混凝土组合梁，包括上钢板与下钢板，所述上钢板与下钢板对称设置，且上钢板与下钢板相对一侧延伸长度方向均设置有弧状凸条，所述上钢板与下钢板之间沿其长度方向均匀焊接有抗剪筋单元。本发明由于抗剪筋单体一与抗剪筋单体二均由四根弧状钢筋首位焊接而成，且抗剪筋单体一与抗剪筋单体二对边两根弧状钢筋交叉设置，提高了抗剪筋单体一与抗剪筋单体二在上钢板与下钢板之间空间承载面积，提高了其抗压以及抗弯矩性能，并且由于抗剪筋单体一与抗剪筋单体二相邻一侧的弧状钢筋呈“V”型，在受到梁受到压迫时，相邻抗剪筋单元侧边的弧状钢筋相互抵触能将力分解至整个梁的径向，进一步提高了梁抗压以及抗弯矩性能。
