Anchor bolt Manufacturer High strength bolt DISC-LOCK lock nut consists of two parts, each part has staggered CAM. Since the slope Angle of the internal wedge design is greater than the nut Angle of the bolt, this combination is tightly snapped into one whole. When vibration occurs, the raised parts of the DISC-LOCK lock nut move with each other to produce lifting tension, thus achieving the locking effect. There is no uniform standard for determining heavy steel structure and light steel structure, and many experienced designers or project managers often cannot fully understand it, but we can comprehensively consider and judge some data:

1, workshop lifting weight: greater than or equal to 25 tons, can be regarded as heavy steel structure.

2, the amount of steel per square meter: greater than or equal to 50KG/㎡, can be considered to be heavy steel structure.

3, the main component steel plate thickness: greater than or equal to 10mm, light steel structure is used less.

In addition, there are some reference values: such as cost per square meter, z large component weight, z large span, structural form, eave height and so on. These can provide empirical data when determining whether a plant is heavy or light steel. Of course, many buildings are made of light and heavy steel. But some can certainly be said to be heavy steel: such as: petrochemical plant facilities, power plant buildings, long-span stadiums, exhibition centers, high-rise or super high-rise steel structures.

? In fact, there is no heavy steel in the national specifications and technical documents. In order to distinguish the steel structure of light houses, ordinary steel structures can be called "ordinary steel". Because the range of ordinary steel structure is very wide, it can include a variety of steel structures, regardless of the size of the load, and even a lot of content of light steel structure, the technical specifications of light house steel structure only specify some more specific content for its "light" characteristics, and the scope is limited to single-layer portal rigid frame.
