H-shaped steel-concrete composite beam
The invention discloses an H-shaped steel-concrete composite beam. The H-shaped steel-concrete composite beam comprises an upper steel plate and a lower steel plate which are symmetrically arranged; arc-shaped convex faces are arranged on the opposite sides of the upper steel plate and the lower steel plate in the width directions of the upper steel plate and the lower steel plate; shear-resistantrib units are uniformly welded between the upper steel plate and the lower steel plate in the length directions of the upper steel plate and the lower steel plate; each shear-resistant rib unit comprises two shear-resistant rib single bodies which are symmetrically arranged; and each shear-resistant rib single body comprises a lower arc-shaped reinforcing steel bar which is tightly attached to the lower arc surface in an inclined crossing mode and an upper arc-shaped reinforcing steel bar which is tightly attached to the upper arc surface in an inclined crossing mode. According to the H-shaped steel-concrete composite beam, when a certain position is pressed to cause deformation of diagonal steel bars, the two diagonal steel bars may push or pull rhombic single bodies to deform, namely, corresponding hinge blocks and female hinge blocks relatively move or oppositely move; as the adjacent male hinge blocks and female hinge blocks are connected through bolts, the adjacent rhombic singlebodies can be driven to deform; and in this way, the force is decomposed to the shear-resistant rib units arranged in the whole length direction, so that the bearing capacity of the beam body is greatly improved.
本发明公开了一种H型钢混凝土组合梁，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沿其宽度方向设置有弧状凸面，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，所述抗剪筋单元包括两个对称设置的抗剪筋单体，所述抗剪筋单体包括紧贴下弧面斜跨设置的下弧形钢筋以及紧贴上弧面斜跨设置的上弧形钢筋。本发明当某处受到压迫导致斜拉钢筋产生形变时，两个斜拉钢筋会推动或拉动其的菱形单体形变，即其对应铰接块和母铰接块相对移动或相向移动，由于相邻公铰接块和母铰接块之间通过螺栓连接，故可带动其相邻菱形单体发生形变，如此将力量分解至整个长度方向上设置的抗剪筋单元上，大大提高了梁体承重力。
