How to store and install high-strength bolts?

High-strength bolts are called high-strength bolt joints. These bolts are commonly called high-strength bolts and are currently widely used in various construction industries. 1. When high-strength bolts leave the factory, they must be manufactured and supplied by the manufacturer according to the batch number, and must be assembled at the factory. 2. The composition of high-strength bolts should meet industry standards and relevant requirements. 3. Storage and delivery of supplies. During the whole process of high-strength bolting, boxing, unloading and shipping, it must be lightweight and care must be taken to avoid packaging. 4. When destroying the installation, attention should be paid to the external thread part of the high-strength bolt. 5. When packing high-strength bolts, the specifications, models and product batch numbers of the packed high-strength bolts should be clearly marked. 6. Classify and store according to the delivery cycle. If the high-strength bolts are stored in the indoor warehouse, the amount of deposition should not exceed three layers. Otherwise, it will not only be unfavorable for transportation, but also prone to the risk of collapse. In the warehouse where high-strength bolts are stored, it is necessary to carry out indoor waterproofing work and ensure long-term protection. 7. It is drying, must avoid rust and stains from being wiped. This is also to avoid changes in the torque index of high-strength bolts and product damage. 8. Only by strictly implementing the warehouse regulations to store high-strength bolts can the product be maintained for a longer period of time. In order to be on the safe side, Maijin needs to recheck the high-strength bolts after half a year of storage, and it is better to do a test before using them. 1. Before assembling the steel frame structure, the burrs, burrs and welding spatters should be removed. The friction surface should be kept dry and clean, and should not work in the rain. 2. The matching high-strength bolts are stored separately according to the production batch number, and should be used in the same batch. 3. The form and specification of high-strength bolts shall comply with the design scheme. 4. The test results of the anti-sliding strength of the high-strength bolted joints should meet the requirements of the design plan, and the joint surfaces of the components should be consistent with the surface conditions of the joint surfaces of the test pieces.
