Concrete plate steel-concrete connecting interface anti-cracking structure and preparation method thereof
The invention discloses a concrete plate steel-concrete connecting interface anti-cracking structure and a preparation method thereof. The concrete plate steel-concrete connecting interface anti-cracking structure comprises an end connecting part arranged at the end of a concrete plate. The end connecting part comprises a vertical plate located on the side face of the concrete plate. A thickeningplate is arranged between the vertical plate and the concrete plate. Pull rod assemblies connected with rebars in the concrete plate are mounted on the thickening plate. The pull rod assemblies comprise high-strength pull rods mounted on the concrete plate, the ends of the high-strength pull rods are sleeved with high-strength nuts, and the bottom faces of the high-strength nuts are connected withthe thickening plate in an abutting manner. Sleeves are arranged at the positions, on one side of the thickening plate, of the high-strength pull rods, and the tail ends of the high-strength pull rods and the rebars are connected in a sleeved manner through threaded sleeves. The end connecting part comprises a cross plate connected with the bottom face of the concrete plate, one end of the crossplate is connected with the vertical plate, and reinforcing ribs are arranged between the bottom of the cross plate and the vertical plate. The problem that in the prior art, the anti-cracking strength of a connecting interface in bolting and welding connection is insufficient can be solved, and the concrete plate steel-concrete connecting interface anti-cracking structure is good in space performance and high in anti-cracking performance.
本发明公开了一种混凝土板钢混连接界面抗裂结构及其制备方法，其包括设置于混凝土板端部的端部连接件，所述端部连接件包括位于混凝土板侧面的竖向板，竖向板与混凝土板间设置有补厚板，补厚板上安装有与混凝土板内钢筋连接的拉杆组件，所述拉杆组件包括安装于混凝土板上的高强拉杆，高强拉杆的端部套设有高强螺母，高强螺母的底面与补厚板抵接；高强拉杆位于补厚板一侧设置有套管，高强拉杆末端通过螺纹套与钢筋套接；端部连接件包括与混凝土板底面相接的横向板，横向板的一端与竖向板相接，横向板的底部与竖向板间设置有加劲肋。本发明能够解决现有技术中栓焊连接的连接界面抗裂强度不足的问题，空间性能好、抗裂性能强。
