Building wall

Abstract

Provided is a building wall capable of substantially preventing the falling-off of an overlay face member from an underlay face member caused by deformation of an overlay face member during a fire, even in a case where the amount of adhesive and the like used for connecting the underlay face member and the overlay face member is reduced. A building wall 100 is provided with at least an underlay face member 30 A and an overlay face member 20 A, the underlay face member 30 A directly or indirectly attached to a stud 40 , the overlay face member 20 A being an indoor-facing member and connected to the underlay face member 30 A, a plurality of said overlay face members 20 A are installed with a first joint 25, 26 therebetween, and wherein a pair of said overlay face members 20 A, by which the first joint 25, 26 is interposed, are connected together by a connecting member 60, 60 A, 60 B that straddles the first joint 25, 26.

1 . A building wall provided with at least an underlay face member and an overlay face member, the underlay face member directly or indirectly attached to a stud, the overlay face member being an indoor-facing member and connected to the underlay face member,
 wherein a plurality of said overlay face members are installed with a first joint therebetween, and   wherein a pair of said overlay face members, by which the first joint is interposed, are connected together by a connecting member that straddles the first joint.   
     
     
         2 . The building wall according to  claim 1 , wherein the connecting member has a first component straddling the first joint on an indoor-side surface of the overlay face member, and the first component is connected to an indoor-side surface of the overlay face member via a first bonding material. 
     
     
         3 . The building wall according to  claim 1 , wherein the connecting member includes a first component that straddles the first joint on a back surface of the overlay face member opposite to an indoor side of the overlay face member, and the first component is connected to the back surface via a first bonding material. 
     
     
         4 . The building wall according to  claim 2 , wherein the first joint is a gapped joint, and the connecting member further includes a second component fitted in the first joint, and the second component is connected to the underlay face member via a second bonding material. 
     
     
         5 . The building wall according to  claim 4 , wherein a plurality of said underlay face members are installed with a second joint therebetween, and the second bonding material is provided at a position corresponding to the second joint exposed to the gapped joint. 
     
     
         6 . The building wall according to  claim 4 , wherein the connecting member is formed of a hat joiner that is provided with two hat parts and a protrusion connecting the two hat parts together, the two hat parts are the first component, and the protrusion is the second component. 
     
     
         7 . The building wall according to  claim 1 , further comprising a steel plate disposed between the overlay face member and the underlay face member, wherein the steel plate functions as a support base that supports, in a cantilever manner, a retrofit-type member that is retrofitted to an indoor-side that is located more inwardly than the overlay face member. 
     
     
         8 . (canceled) 
     
     
         9 . (canceled) 
     
     
         10 . The building wall according to  claim 1 , wherein the building wall is a partition wall, and a face member unit is installed on one or both surfaces of the stud, the face member unit including at least the plurality of said overlay face members and the underlay face member. 
     
     
         11 . The building wall according to  claim 1 , wherein the building wall is an indoor-side wall of an exterior wall, and a face member unit is installed on one surface of the stud, the face member unit including at least the plurality of said overlay face members and the underlay face member. 
     
     
         12 . The building wall according to  claim 3 , further comprising a steel plate disposed between the overlay face member and the underlay face member, wherein the steel plate functions as a support base that supports, in a cantilever manner, a retrofit-type member that is retrofitted to an indoor-side that is located more inwardly than the overlay face member. 
     
     
         13 . The building wall according to  claim 12 , wherein the first component is the steel plate, and the steel plate has both a function of connecting the pair of said overlay face members and a function of serving as the support base. 
     
     
         14 . The building wall according to  claim 13 , wherein an area of the steel plate is 40% or less a total area of the building wall.
