Ribbon steel plate type stirrup for beam-column joint area of stiff structure

LI YONGQIANG / SONG SHUYANG / LI XUDONG / LIU WANGYUE / GAO SHOUSHENG

The invention provides a stiff structure beam-column joint area annular band steel plate type stirrup, which belongs to the technical field of building construction, and comprises a section steel column main beam, a transverse stirrup, a longitudinal rib group and a connecting mechanism, and the supporting plates are arranged between every two adjacent groups of multi-web supporting steel plates and are symmetrically distributed along the horizontal center lines of the multi-web supporting steel plates in the vertical direction. According to the invention, the whole multi-web support steel plate is continuously subjected to the acting stress towards the section steel column main beam, so that the multi-web support steel plate keeps the clinging and stress effects with the section steel column main beam, the transverse stirrups are not directly contacted with the section steel column main beam, and the clinging and fixing effects with the section steel column main beam are kept through the multi-web support steel plate; the section steel column main beam can be restrained through the multi-web supporting steel plate, and the one-way compression resistance and shear strength of the beam column joint mechanism are improved.

本发明提供了一种劲性结构梁柱节点区环带钢板式箍筋，属于建筑施工技术领域，包括型钢柱主梁、横向箍筋和纵向筋条组，型钢柱主梁的侧面翼板通过螺栓固定安装有多腹板支撑钢板，还包括连接机构，在每相邻两组多腹板支撑钢板之间设置，并在垂直方向沿多腹板支撑钢板的水平中线对称分布。该发明，使多腹板支撑钢板整体持续受到朝向型钢柱主梁方向的作用应力，使多腹板支撑钢板保持与型钢柱主梁的紧贴和应力效果，横向箍筋不直接与型钢柱主梁相接触，通过多腹板支撑钢板与型钢柱主梁保持贴合和固定效果，可以通过多腹板支撑钢板对型钢柱主梁起到约束效果，提高了梁柱节点机构的单向抗压及抗剪强度。
