Description

Technical Field

[0001] The utility model relates to a pressing plate device for a steel structure building, belonging to the field of steel structure buildings. Background Art

[0002] The crimping plate is a commonly used accessory for connecting two ends of a steel structure, wherein a plurality of holes are provided at the end of the steel structure, and a plurality of circular holes matching the holes on the end of the steel structure are provided on the crimping plate. After the circular holes on the crimping plate are aligned with the holes on the end of the steel structure, high-strength bolts are passed through the channel formed by the circular holes and the holes and nuts are screwed on, thereby connecting the two steel structures using the crimping plate. Since a large number of fasteners formed by high-strength bolts and nuts need to be installed between the crimping plate and the end of the steel structure, during the assembly process, a wrench or the like needs to be used to limit the head of the high-strength bolt to facilitate tightening the nut. Each high-strength bolt needs to be positioned using a wrench, so that the position of the wrench needs to be constantly changed among multiple high-strength bolts, and then the nut needs to be tightened using another wrench. Since the above method needs to position each high-strength bolt, the installation efficiency of the high-strength bolts is low. Utility Model Content
