Load-bearing panel and building frame structure

A building frame structure comprising a rectangular-shaped composite surface material made of wooden plywood and a metal plate stacked on each other, the composite surface material being placed on a front surface of a structural plane surrounded by:

• a pair of horizontal members arranged in parallel with each other so as to have a certain distance in a vertical direction;
• and a pair of upright members arranged in parallel with each other so as to have a certain distance in a horizontal direction, such that four side edges of the composite surface material are attached to the structural plane by driving nails, wherein
• spacing between the nails in a center part of each of the four side edges in a length direction of the composite surface material is smaller than spacing between the nails in both end parts of each of the four side edges.

A building frame structure comprising a rectangular-shaped composite surface material made of wooden plywood and a metal plate stacked on each other, the composite surface material being placed on an upper surface of a structural plane surrounded by:

• a pair of horizontal members arranged in parallel with each other so as to have a certain distance in a horizontal direction;
• and a pair of flat laying members arranged in a direction orthogonally intersecting the pair of horizontal members so as to have a certain distance in the horizontal direction, such that four side edges of the composite surface material are attached to the structural plane by driving nails, wherein
• spacing between the nails in a center part of each of the four side edges in a length direction of the composite surface material is smaller than spacing between the nails in both end parts of each of the four side edges.
