A structural hanger providing a means for connecting a horizontal or sloped mass timber panel to a wall with sheathing without impairing the fire resistance rating of the wall. One embodiment comprises a plurality of legs, including a first leg with a means for connecting the hanger to a mass timber panel, a second leg with a means for connecting the hanger to structural members within the wall, and a third leg connecting the first and second leg to each other and extending through the sheathing mounted to the wall.

A concealed connector for connecting a first structural component to a second structural component includes a connection portion and a connection plate. The connection portion attaches to the second structural component. The connection plate attaches to the first structural component. The connection plate is coupled to the connection portion and extends into a slot in the first structural component. The connection plate has a perforated region that is penetrated by at least one fastener to attach the connection plate to the first structural component. The perforated region is deformed by the at least one fastener to permit the at least one fastener to penetrate the perforated region of the connection plate.

An opening portion (2) having a height of two stories or more is provided in an exterior wall that faces a multi-height space. At least one wind-resistant post (3) is composed of a glued laminated timber, and has a cross-section in which a long axis dimension thereof is at least twice as long as a short axis dimension thereof. The wind-resistant post (3) is disposed upright and extends continuously through upper and lower floors, with a long axis direction of the cross-section being orthogonal to an opening plane. This wind-resistant post (3) exerts a high resistance against wind pressure acting on the opening portion, thereby achieving a post and beam structure that adds excellent spaciousness and visual appeal to the opening portion.

A connecting metal (1) includes a tenon pipe (13) having through-holes (132) for fixing the tenon pipe (13) by drift pins or bolts, and a plate (12) joined at an end of the tenon pipe (13) and having through-holes (122) for fixing the plate (12) by drift pins or bolts, the tenon pipe (13) and the plate (12) being joined with each other in a substantially racket-like shape. A pair of slits (131) for receiving the plate is formed at the end of the tenon pipe (13), each of the slits (131) being defined by a first side edge and a second side edge that are bent inwardly. The plate (12) is inserted in the pair of slits (131) and joined with the tenon pipe (13) by welding, with no protrusion of weld reinforcement out of an outer periphery of the tenon pipe (13).

A glulam construction method suitable for relatively small-sized wooden buildings is disclosed. Each joint metal has its plate portion and pipe portion joined in a racket-like shape. At an end of a column, a slit is formed to open at a column end surface and to extend in a column width direction. At an abutment part in a beam abutting on the column end surface, mortises penetrating in a beam depth direction are formed at two positions appropriately spaced from each other in a span direction. Each joint metal has its pipe portion fitted in the corresponding mortise and has its plate portion fitted in the slit of the column. The joint metals are fixed in the column and the beam by drift pins or bolts and thereby establish rigid connection therebetween.

An installation and construction method of a wall panel is provided for installing the wall panel to a pair of wooden columns and a wooden horizontal member, the wooden columns being installed in a standing manner so as to be spaced apart from each other, the wooden horizontal member being installed to the wooden columns. The method includes: forming the wall panel by connecting mutually adjacent end portions of a plurality of surface members in a horizontal direction by a half column extending in a vertical direction, studs being fixed on first plate surfaces of the plurality of surface members; and after installing the wooden horizontal member to the wooden columns and adjusting erection of the wooden columns, fixing edge end portions of the surface members of the wall panel to front surfaces of the wooden columns and a front surface of the wooden horizontal member.

A concealed connector for connecting a first structural component to a second structural component includes a connection portion and a connection plate. The connection portion attaches to the second structural component. The connection plate attaches to the first structural component. The connection plate is coupled to the connection portion and extends into a slot in the first structural component. The connection plate has a perforated region that is penetrated by at least one fastener to attach the connection plate to the first structural component. The perforated region is deformed by the at least one fastener to permit the at least one fastener to penetrate the perforated region of the connection plate.

At a joint between a butt end face of a lower end of the column material made of wood and a butt end receiving face of the column base fitting that supports the butt end face, an outer edge of the butt end face extends more outward than an outer edge of the butt end receiving face, and at a corner between the butt end face and a side face of the column material, a water draining function that causes water running along the side face of the column material to drop downward is provided.

This building comprises a foundation, a main building part that is provided to the foundation and that has a framework structure, and a roof that is provided to the main building part and that has a truss structure. Moreover, a method for constructing the building includes: a first step for forming the foundation; a second step for creating the main building part having a framework structure on the foundation; and a third step for attaching, to the main building part, a roof frame having a pre-assembled truss structure.

A bearing wall partitions into a plurality of openings and in a vertical direction between adjacent column members by bridging a beam member that serves as a window sill between intermediate portions of the adjacent column members in a framework. Both end portions of the beam member are tied to intermediate portions of the adjacent column members via metal joints. A window is installed in the upper opening, and a peripheral end portion of the structural plywood is fixed to the lower opening with a nail. The structural plywood is fixed with nails at a rough nail pitch.
