Anti-pulling flexible anti-shearing self-tapping screw
The invention discloses an anti-pulling flexible anti-shearing self-tapping screw which is used for connecting a cladding wall plate and a steel rib frame of a cold-formed thin-walled steel-cladding wall plate combined shear wall body and comprises five structural forms, the same structure comprises a nut, a screw body section and a screw tail section, and the four structures further comprise external thread sleeves made of elastic materials. The external thread sleeves are located between the screw cap and the screw body section, the long connecting rod and the long spring which are fixedly connected with the screw cap and the screw body section and the upper short connecting rod and the lower short connecting rod which are connected with the screw cap and the screw body section respectively are wrapped in the external thread sleeves of the four structures respectively, and the short spring is connected between the upper short connecting rod and the lower short connecting rod; the five structures respectively have different rigidities and deformability and can be flexibly selected according to different connecting positions of the wallboards, when the composite wall body is sheared, part of connecting stress is released, cracking and pressure-bearing damage of the ends of the covering wallboards are delayed, the stress performance of the connecting positions is improved, the lateral resistance and anti-seismic performance of the wall body are improved, and the maintenance cost of the structure is reduced.
本发明公开了一种抗拔柔性抗剪自攻螺钉，用于连接冷弯薄壁型钢‑覆面墙板组合剪力墙体的覆面墙板与钢骨框架，包括五种结构形式，它们的相同结构包括螺帽、螺身段和螺尾段，其中四种结构还包括弹性材质的外螺纹套管，外螺纹套管位于螺帽和螺身段之间，四种结构的外螺纹套管中分别包覆固定连接螺帽和螺身段的长连杆、长弹簧及分别连接螺帽和螺身段的上下短连杆、上下短连杆之间连接短弹簧，另外一种将螺身段的中上部设置为空心段，五种结构分别具有不同的刚度和变形能力，可根据墙板的不同连接位置灵活选用，复合墙体受剪时释放部分连接应力，延缓覆面墙板板端开裂和承压破坏，改善连接处受力性能，提高墙体抗侧能力和抗震性能，降低结构维护成本。
