High-strength scaffold fastener
The invention provides a high-strength scaffold fastener. The high-strength scaffold fastener comprises at least two pressing plates, a middle connecting piece, a screw rod and a nut. The middle connecting piece is used for pre-fixing the two scaffold pipes; the pressing plates are respectively used for holding scaffold pipes; the screw rod penetrates through the pressing plate and the middle connecting piece and is locked through the nut; the first end of the screw rod is provided with a limiting part used for preventing the nut from falling off, and the nut is arranged in an area between the second end of the screw rod and the limiting part and moves in a threaded mode; the pressing plate and the middle connecting piece are made of high-strength alloy which contains 0.05 wt%-0.5 wt% of carbon and 0.0001 wt%-0.01 wt% of boron, the surface of the high-strength alloy is provided with a zinc-aluminum or zinc-aluminum-magnesium or aluminum-magnesium alloy or aluminum-magnesium alloy coating formed through a hot-dip coating method, and the yield strength of the high-strength alloy ranges from 300 MPa to 800 MPa.
本申请提供了一种高强度的脚手架扣件，包括至少两个压板、中间连接件、螺杆及螺母；所述中间连接件用于预固定两根脚手架管；所述压板分别用于抱合脚手架管；所述螺杆穿过所述压板及中间连接件，并通过所述螺母进行锁紧；所述螺杆的第一端设置有用于防止螺母脱落的限位部，所述螺母置于所述螺杆的第二端与限位部之间的区域内螺纹活动；所述压板及中间连接件为含碳0.05‑0.5wt，含硼0.0001‑0.01wt%，表面有采用热浸涂层方法形成的锌铝或锌铝镁或铝镁合金或铝镁合金镀层，屈服强度在于300兆帕和800兆帕之间的高强度合金。
