Framework wall structure, building and framework wall construction method

Abstract

A framework wall structure, a building and a framework wall construction method that may improve structural performance against horizontal force and prevent damage to and around a joining member are provided. A viscoelastic member is sandwiched between joining surfaces of an adjacent member set formed of a stud, a lintel receiving portion and a block so that the viscoelastic member absorbs energy of horizontal force and absorption performance of vibration may be improved. Also, the viscoelastic member may decrease a shear force applied to a nail, prevent that the nail is deformed and a nail hole is enlarged, and prevent damages of the nail and a nailed member.

1 . A framework wall structure, wherein a floor body or a roof body is supported on an upper side of a wall body, the wall body comprising:
 a framework having a top plate, a bottom plate, and right and left studs; and   a surface material fixed to the framework;   the framework wall structure comprising:   a vertical member extending vertically along each of the right and left studs and supporting a horizontal member;   the horizontal member extending horizontally along the top plate or the bottom plate, wherein   the right and left studs arg adjacent to each other, each of the right and left studs and the vertical member, the top plate and the horizontal member, the bottom plate and the horizontal member, and the horizontal members form an adjacent member set so that a surface along a longitudinal direction is a joining surface, and joining surfaces are joined by joining members to oppose to each other, and wherein   a sheet-like viscoelastic member is attached so as to be sandwiched between at least one pair of the joining surfaces of the adjacent member set.   
     
     
         2 . The framework wall structure according to  claim 1 , wherein the viscoelastic member is provided to the adjacent member set placed at an intersection at which at least two wall surfaces formed by the framework and the surface material intersect. 
     
     
         3 . The framework wall structure according to  claim 1 , wherein
 the vertical member is a lintel receiving portion provided surrounding an opening portion, or a block provided between the studs or between the stud and the lintel receiving portion, and wherein   the horizontal member is a lintel provided above the opening portion, a head binder provided above the top plate, a joist provided above the top plate or below the bottom plate, or a floor board provided above the joist.   
     
     
         4 . A building comprising, the framework wall structure according to  claim 1 . 
     
     
         5 . A framework wall structure method for making a floor body or a roof body to be supported on an upper side of a wall body, the wall body comprising:
 a framework having a top plate, a bottom plate, and right and left studs; and   a surface material fixed to the framework;   the framework wall structure method including:   the framework wall structure method including:   preparing a vertical member extending vertically along each of the right and left studs and supporting a horizontal member, and the horizontal member extending horizontally along the top plate or the bottom plate;   forming an adjacent member set with the right and left studs being adjacent to each other, each of the right and left studs and the vertical member, the top plate and the horizontal member, the bottom plate and the horizontal member, and the horizontal members, with a surface along a longitudinal direction being a joining surface;   joining by joining members such that the joining surfaces are opposed to each other; and   attaching a sheet-like viscoelastic member at least one pair of the joining surfaces of the adjacent member set.
