Prefabricated Post Assembly With Modular Bolted Connection

The connection system is segmented into modular components: a connection plate with guide holes, coupling plates with coupling holes, and separate bolts. This segmentation allows pre-fabrication of components with precise alignment features, enabling rapid on-site assembly without welding while maintaining joint strength through the bolted connection system.

The guide holes are preliminarily formed in the connection plate and coupling plates during manufacturing, establishing precise alignment paths before assembly. This preliminary action ensures that during construction, workers simply need to insert bolts through the pre-aligned holes, dramatically reducing construction time and eliminating the need for skilled welding while preserving joint strength.

The welding process is completely extracted from the connection system and replaced with a mechanical bolted connection. This eliminates the sources of unreliability associated with welding (stress concentration, poor welding quality) while maintaining joint strength through the engineered coupling plate and bolt assembly, which distributes loads more evenly without creating stress concentration points.

The coupling plate acts as an intermediary component between the horizontal post and vertical post, providing a standardized interface that distributes connection forces evenly. This intermediary element eliminates direct welding between structural members, removing the reliability issues of stress concentration while maintaining strong mechanical connection through multiple bolts.

The connection system is designed to be self-aligning through the guide holes in the coupling plate, which automatically guide the bolts into the correct positions. This self-service feature eliminates the need for skilled welding engineers, allowing ordinary construction workers to assemble the connection by simply inserting and tightening bolts, dramatically improving ease of operation while maintaining joint strength.

The complex welding mechanical process is replaced with a simple mechanical bolted connection system. The guide holes and coupling holes provide automatic alignment, and the bolts provide straightforward fastening that requires no specialized welding skills. This substitution maintains joint strength through proper mechanical fastening while dramatically improving ease of operation for construction workers.
