How to store high-strength bolts:
1. When the high-strength bolts are factory-set, it is necessary for the manufacturer to produce and deliver according to the batch number, and consist of factory settings.
2. The composition of high-strength bolts should conform to national industry standards and relevant requirements. High-strength bolted joints must be paired in the same batch
3. Storage and delivery of supplies. In the whole process of high-strength bolt connection, boxing, unloading and transportation, it is necessary to be lightweight, and care should be taken to avoid packaging.
4. When installing damaged, pay attention to part of the external thread of the high-strength bolt.
5. When packaging high-strength bolts, the standards for packaging high-toughness bolts and the product batch number should be established;
6. Carry out classification and storage according to the supply cycle. If the high-strength bolts are stored in the warehouse in the room, the deposition amount cannot exceed three layers. Otherwise, it will not only be unfavorable to transport, but also very prone to the risk of collapse. In the warehouse where high-strength bolts are stored, it is necessary to do a good job of preventing moisture in the room and ensure long-term safety protection.
7. It is dry and necessary to avoid rust and stains from being wiped off. It is to avoid the large variation of the torque index of high-strength bolts, and the product is quoted. storehouse
8. Only by strictly implementing the warehouse rules and storing high-strength bolts can the products be maintained for a longer time. In order to ensure that the safety is correct, the high-strength bolts should be reviewed for more than half a year, and it is best to do a test before use.
Installation regulations for high-strength bolts
1. Before assembling the steel frame structure, the broken edges, vibration lines and welding spatters should be disassembled. The friction surface should be kept dry, clean and tidy, and people should not work in the rain.
2. The matching high-strength bolted connections are stored separately according to the production batch number, and should be used in the same batch number.
3. The method and standard type of high-strength bolts should conform to the rules of the design scheme.
4. The results of the anti-slip index test of the high-strength bolted joint should conform to the rules of the design scheme, and the joint surface of the member should be consistent with the appearance of the joint surface of the specimen.
