Publication number: 20150143764Abstract: 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.Type: ApplicationFiled: March 24, 2014Publication date: May 28, 2015Applicant: KABUSHIKI KAISHA GRAPEInventor: Yuichi MASAKI
