Installation structure of base of exterior wall

Abstract

In external renovation of a wooden framework house in which a bearing face material is used as an exterior wall base member, is capable of partly increasing the wall strength factor, thereby providing a high degree of freedom of seismic design and, furthermore, facilitating installation of an exterior material such as ceramic siding after seismic reinforcement. A reinforcement member for preventing punching shear is interposed. Between a bearing face material of a wall that is required to have a high wall strength factor by a seismic design and a nailhead of a nail for fixing the bearing face material to a structural member.

         4 . The installation structure of a base of an exterior wall according to any of  claims 1 , wherein a type and a thickness of the bearing face material of the wall that is required to have a high wall strength factor by the seismic design are the same as those of a bearing face material of a wall that is not required to have a high wall strength factor. 
     
     
         5 . The installation structure of a base of an exterior wall according to any of  claims 1 , wherein the nails are of a single type and a single size. 
     
     
         6 . The installation structure of a base of an exterior wall according to any of  claims 1 , wherein the reinforcement member is a thin steel sheet. 
     
     
         7 . The installation structure of a base of an exterior wall according to any of  claims 1 , wherein the reinforcement member is a sheet selected from a glass fiber sheet and a carbon fiber sheet. 
     
     
         8 . The installation structure of a base of an exterior wall according to  claim 2 , wherein at least two nails are driven in a single, continuous piece of the reinforcement member. 
     
     
         9 . The installation structure of a base of an exterior wall according to any of  claims 2 , wherein a type and a thickness of the bearing face material of the wall that is required to have a high wall strength factor by the seismic design are the same as those of a bearing face material of a wall that is not required to have a high wall strength factor. 
     
     
         10 . The installation structure of a base of an exterior wall according to any of  claims 2 , wherein the nails are of a single type and a single size. 
     
     
         11 . The installation structure of a base of an exterior wall according to any of  claims 2 , wherein the reinforcement member is a thin steel sheet. 
     
     
         12 . The installation structure of a base of an exterior wall according to any of  claims 2 , wherein the reinforcement member is a sheet selected from a glass fiber sheet and a carbon fiber sheet. 
     
     
         13 . The installation structure of a base of an exterior wall according to any of  claims 3 , wherein a type and a thickness of the bearing face material of the wall that is required to have a high wall strength factor by the seismic design are the same as those of a bearing face material of a wall that is not required to have a high wall strength factor. 
     
     
         14 . The installation structure of a base of an exterior wall according to any of  claims 3 , wherein the nails are of a single type and a single size.
