常见问题

如何防止钢结构中的螺栓松动?

选用Nord-Lock钢结构垫圈。其采用Nord-Lock楔形制锁技术,能够承受剧烈振动、位移及动态载荷,确保螺栓始终处于锁紧状态。该连接方案无需二次紧固即可保持长期稳固。

We use HV/HR bolted connections — how can we avoid preload loss and installation issues?

Nord-Lock steel construction washers prevent preload loss, reduce installation errors, and eliminate the need for maintenance. They provide reliable performance where double nuts, pal nuts, or retightening often fail.

Am I allowed to use Nord‑Lock steel construction washers in EN 1090 projects?

Yes. Nord-Lock steel construction washers are designed specifically for EN 1090 and EN 14399 HV/HR bolt assemblies and can be used confidently in preloaded structural joints.

How difficult is it to install Nord-Lock steel construction washers on site?

Very easy. They require no special tools, ensure consistent preload, and are easy to install even in challenging on‑site conditions.

When should I choose Nord-Lock steel construction washers instead of standard Nord-Lock washers?

Use Nord-Lock steel construction washers when working with HV/HR bolts in structural steel applications which are supposed to dynamic loads or movements.

在承受动态荷载或位移的结构钢应用中,当使用HV/HR高强度螺栓时,应选用Nord-Lock钢结构垫圈。 如何根据HV/HR螺栓选择相应尺寸的垫圈?

只需根据HV/HR螺栓规格(M12–M36)选择对应垫圈尺寸即可。Nord-Lock钢结构尺寸指南可简化选型流程。使用时,请将一个Nord-Lock垫圈安装在螺栓头下方,另一个安装在螺母下方。

Nord-Lock钢结构垫圈是否通过极端载荷与振动测试?

是的。产品通过容克振动测试及EN 14399性能标准验证,确保在风载、动态力及温度变化条件下保持其可靠性。

Nord-Lock钢结构垫圈是否具有CE认证标识?

是的。Nord-Lock钢结构垫圈已通过EN 1090认证体系下的CE标识认证。这意味着它们被批准用于承重钢结构,并符合欧盟和英国市场对建筑产品规定的性能与安全要求。 了解更多有关CE认证的信息
