Metal connector for building and jointing structure of building using the same

A metal connector for jointing first and second members of a building to each other, comprising:

• a metal connector body including a bottom plate and a core plate secured vertically to an upper face of said bottom plate, said core plate having a pair of window holes formed at symmetrical locations adjacent opposite longitudinal ends of said core plate;
• a pair of bolts, said bolts being secured at base end portions thereof to inner peripheries of said core plate around said window holes such that the free end portions of said bolts extend into said window holes with spacings left between the free end portions of said bolts and opposing portions of the inner peripheries of said window holes;
• each of said first and second members having a fitting recess formed at jointing end portion thereof in a profile suitable to closely receive corresponding longitudinal halves of said bottom plate and said core plate of said metal connector body, said fitting recesses being open to a bottom of said first and said second members;
• each of said first and second members further having a working window hole formed contiguously with the fitting recess;
• a pair of nuts screwed on the free end portions of said bolts;
• and
• a pair of holding plates inserted in said spacings between said nuts and opposing peripheral portions of said working window holes, and wherein said nuts are turned in a predetermined direction to axially move on said bolts to push against said holding plates, said holding plates thus pushing against the opposing peripheral portions of said working window holes to force said first and said second members to move toward each other until longitudinal ends of said first and said second members are closely contacted with each other.

A jointing structure for a building, comprising:

• a metal connector body including a bottom plate and a core plate secured vertically to an upper face of said bottom plate, said core plate having a window hole formed therein;
• first and second members to be jointed to each other by means of said metal connector body;
• a bolt, said bolt being secured at a base end portion thereof to an inner periphery of said core plate around said window hole such that the free end portion of said bolt extends into said window hole with a spacing left between the free end portion of said bolt and an opposing portion of the inner periphery of said window hole;
• means for connecting a longitudinal end of said metal connector body remote from said bolt to said second member;
• said first member having a fitting recess formed at a jointing end portion thereof in a profile suitable to closely receive said bottom plate and said core plate of said metal connector body, said fitting recess being open to a bottom of said first member;
• said first member further having a working window hole formed contiguously to said fitting recess therein;
• a nut screwed on the free end portion of said bolt;
• and
• a holding plate inserted in said spacing between said nut and an opposing peripheral portion of said working window hole, and wherein said nut is turned in a predetermined direction to axially move on said bolt to push against said holding plate, said holding plate thus pushing against the opposing peripheral portion of said working window hole to force said first member to move toward said second member until a longitudinal end of said first member is closely contacted with said second member.
