Installation requirements and storage methods for high-strength bolts

Installation requirements and storage methods for high-strength bolts

High strength bolts are called high-strength bolt joints. These bolts are commonly referred to as high-strength bolts and are currently widely used in various construction industries.

1. When high-strength bolts leave the factory, they must be produced and supplied by the manufacturer in batches, with a factory combination.

2. The combination of high-strength bolts should comply with national standards and relevant regulations. High strength bolt connection pairs must be matched in the same batch

3. Storage and transportation supply. During the entire process of high-strength bolt connection, box splitting, unloading, and transportation, it is necessary to lightweight and pay special attention to preventing packaging.

When damaging the installation, special attention should be paid to the threaded part of high-strength bolts.

When packaging high-strength bolts, the specifications and product batch number of the packaged high-strength bolts should be clearly indicated;

6. Classify and store according to the delivery date. If high-strength bolts are stored in an indoor warehouse, their accumulation cannot exceed three layers. Otherwise, not only is it not conducive to transportation, but it is also prone to collapse hazards. In the warehouse where high-strength bolts are stored, indoor moisture-proof work must be done well and long-term protection must be ensured.

It is dry and needs to prevent rust and dirt from being applied. This is to prevent the torque coefficient of high-strength bolts from changing and the product from being scrapped. stack

Only by strictly following the warehouse's requirements to store high-strength bolts can products be protected for a longer period of time. For safety reasons, high-strength bolts need to be rechecked after half a year of storage, and it is best to conduct an experiment before use. Before assembling the steel structure, burrs, burrs, and welding spatters should be removed. The friction surface should be kept dry and tidy, and should not work in the rain.

2. High strength bolt connections should be stored separately by batch number and used in the same batch.

3. The form and specifications of high-strength bolts should meet the design requirements.

4. The anti sliding coefficient test results of high-strength bolt joints shall meet the design requirements, and the joint surface of components shall be consistent with the Surface states of the joint surface of the sample.
