Prefabricated reinforced concrete anti-explosion wall vertical mechanical connection structure
The invention provides a vertical mechanical connection structure of a prefabricated reinforced concrete anti-explosion wall, and belongs to the technical field of anti-explosion wall design. Comprising a prefabricated anti-explosion wall, the bottom surface of which is pre-embedded with a first embedded part; a mounting groove is formed in the upper end face of the wall base in advance, the first embedded part is inserted into the mounting groove, a second embedded part is embedded in the wall base in advance, and the second embedded part is located at the bottom of the mounting groove; the upper portion of the pin steel bar is connected with the first embedded part, and the lower portion of the pin steel bar sequentially penetrates through the mounting groove and the second embedded part and extends into the wall base. The connecting block in the first embedded part is inserted into the mounting groove to form an anti-shear key and anti-key groove structure like a steel structure column foot, and the anti-shear key and anti-key groove structure is a first defensive line of an anti-shear system; the second embedded parts pre-embedded in the wall base and the pin steel bars are connected to form a second defensive line of the connecting joint shear-resistant system, and the wall has better shear-resistant performance under the combined action of the connecting structure of the first defensive line and the second defensive line.
本发明提供了一种预制钢筋混凝土抗爆墙竖向机械连接构造，属于抗爆墙设计技术领域。包括：预制抗爆墙，底面上预先埋设有第一预埋件；墙底座，上端面上预先设有安装槽，第一预埋件插入到安装槽内，墙底座内预先埋设有第二预埋件，且第二预埋件位于安装槽槽底；销钢棒，上部与第一预埋件连接，下部依次穿过安装槽和第二预埋件伸入到墙底座内。本发明中第一预埋件中的连接块插入到安装槽内，形成如钢结构柱脚的抗剪键和抗键槽结构，此为抗剪体系的第一道防线；墙底座内预先埋设的第二预埋件和销钢棒的连接成为连接节点抗剪体系的第二道防线，第一道防线和第二道防线的连接构造共同作用使得墙体具有更好的抗剪性能。
