The patent application (Publication Number: US20230407628A1) describes a load-bearing panel for building frame structures. The panel consists of a rectangular base frame made of horizontal and vertical base materials, with a composite surface material of wooden plywood and a metal plate attached to it using nails. The spacing between the nails in the center part of each side edge is smaller than at the end parts, ensuring secure attachment.

Furthermore, the patent application details building frame structures incorporating the load-bearing panel. These structures involve attaching the panel to horizontal and vertical members using fixing tools. The composite surface material, consisting of wooden plywood and a metal plate, is attached to the structural plane with nails, with specific spacing arrangements to ensure stability. The patent also specifies the length range for the center part with smaller nail spacing, as well as the arrangement of nails in a linear or zig-zag manner along the side edges. Overall, the patent aims to provide a secure and efficient load-bearing panel for building frame structures, enhancing construction processes and structural integrity.
