VERTICALITY HOLDER

摘要

PROBLEM TO BE SOLVED: To provide a verticality holder which facilitates formation of orthogonal connection between a horizontal structural member and a vertical structural member of a building unit, and contributes to easy setting/fixture of the buidling unit after transportation of the building unit to the site. SOLUTION: The verticality holder is formed of a main rod body 2, a horizontal fixing portion 3, and a vertical fixing portion 4, and has the horizontal fixing portion 3 fixed to the horizontal structural member 51 and the vertical fixing portion 4 fixed to the vertical structural member 52. When an intersection point between the horizontal structural member 51 and the vertical structural member 52 is represented by O, a virtual intersection point between the horizontal structural member 51 and a center line of the main rod body 2 by P, a virtual intersection point between the vertical structural member 52 and a center line of the main rod body 2 by Q, a length of the main rod body 2 by z1, a length between one end 21 of the main rod body 2 and the virtual intersection point P by z2, a length between the other end 22 of the main rod body 2 and the virtual intersection point Q by z3, and a length of a segment PQ by z, respectively, an equation of z = z1+ z2+ z3holds. Further, a length x of a segment OP, a length y of a segment OQ, and the length z of the segment PQ satisfy an equation of x2+ y2= z2. COPYRIGHT: (C)2004,JPO
