Patent number: 9758963Abstract: A bearing wall includes a pair of vertical members that are joined to upper and lower horizontal members of a building so as to be spaced apart in a horizontal direction; and a wall surface member that includes a first joint portions joined to one of the vertical members, that includes a second joint portions joined to another of the vertical members, and that includes circular-shaped opening portions that are spaced apart in an up-down direction between the pair of vertical members so as to be disposed in a single column. A separation distance between a center of one opening portion and a center of an opening portion that is adjacent to the one opening portion in the up-down direction is shorter than a horizontal separation distance between the first joint portions and the second joint portions.Type: GrantFiled: September 9, 2014Date of Patent: September 12, 2017Assignees: NIPPON STEEL & SUMITOMO METAL CORPORATION, NS HI-PARTS CORPORATIONInventors: Yoshimichi Kawai, Shigeaki Tohnai, Shinichiro Hashimoto, Kazunori Fujihashi, Atsushi Sato, Tetsuro Ono

Patent number: 8875452Abstract: A energy dissipating metal plate joins a pair of target members and exhibits energy dissipating performance corresponding to a relative displacement between the target members. The energy dissipating metal plate includes: a first joint part to be joined to one of the target members; a second joint part to be joined to other of the target members; and vibration dissipating parts which are provided on a transmission path of tensile force and compression force between the first joint part and the second joint part, and which have slits. Each of the first joint part and the second joint part is formed in a strip shape substantially parallel to a direction of the relative displacement.Type: GrantFiled: June 16, 2010Date of Patent: November 4, 2014Assignee: Nippon Steel & Sumitomo Metal CorporationInventors: Yoshimichi Kawai, Fuminobu Ozaki

Patent number: 8590256Abstract: The present invention provides a joining structure of a roof truss using thin light-gauge shaped steel. In a joining structure for joining a subsidiary roof with a main roof, a valley bracket formed by bending a thin steel sheet is inserted and disposed in the longitudinal valley direction of a joining member for joining a rafter forming the subsidiary roof with a truss or a rafter forming the main roof. In a joining structure in which a roof truss upper chord member or a rafter intersects a wall on the upper surface of the wall, a bracket formed by bending a thin steel sheet is disposed at the intersection of these members and fixes the roof truss upper chord member or the rafter to the wall.Type: GrantFiled: December 4, 2008Date of Patent: November 26, 2013Assignee: Nippon Steel & Sumitomo Metal CorporationInventors: Yoshimichi Kawai, Jun Shimizu

Patent number: 7882665Abstract: The present invention provides construction configurations and a construction method for steel houses that eliminate the shortcoming of the conventional platform construction method for steel houses that complicates the structure because of the need to use metal reinforcements without losing the advantage of the conventional method that facilitates the construction work by using wall panels. After constructing the ground story wall (lower story wall) 22 by attaching wall panels 21 for the ground story to through vertical frame studs 20 extending to upper floors, the second story wall (upper story wall) 23 is constructed by attaching wall panels 21 for the upper Story to the through vertical frame studs 20. Of the wall panels 21 disposed along the four sides of the lower story, the top ends 29 of the two opposite wall panels 21b are positioned lower than the top ends 29a of the lower story wall panels 21a on the other two opposite sides.Type: GrantFiled: July 21, 2005Date of Patent: February 8, 2011Assignee: Nippon Steel CorporationInventors: Yoshimichi Kawai, Kazunori Fujihashi, Shigeaki Tohnai
