Other specification requirements for high-strength bolt installation

No matter what type of high-strength bolt it is, it is necessary to conduct a safety inspection on the production and processing process of high-strength bolts, and finally scientifically store and transport them to the construction site for standard installation. I believe all partners have a very detailed understanding! High strength bolts, as one of the fasteners, have extremely strict production processes and relatively strict operating standards in all aspects. However, few people can achieve some small details, which requires sorting and implementation. Now, let me organize some details.

When assembling high-strength bolt connection pairs, the side of the nut with a round table should face the side with chamfered washers. In general, when assembling high-strength bolts with large hexagonal heads, the chamfered side of the washer under the bolt head should face the bolt head. When installing high-strength bolts, construction personnel are strictly prohibited from forcefully penetrating the bolts (referring to hammering here). If the hole cannot be freely penetrated, it must be trimmed with a reamer. After finishing, the maximum diameter of the hole should be less than 1.2 times the diameter of the bolt. When repairing holes, in order to prevent iron chips from falling into the overlap of the plate, all bolts around should be tightened and checked for firmness before reaming. The operation can only be carried out after the plate is stacked tightly. It should be noted that it is strictly prohibited to use gas cutting to expand holes in a certain area. The on-site use of gas cutting for hole expansion is convenient and requires dedicated supervision.
