A joint metal includes a securing plate and a coupling plate. The securing plate is secured to the side surface of a support material. The coupling plate is disposed to project from the securing plate toward the horizontal structural member side. The coupling plate is coupled in a state inserted into a groove formed over the vertical direction on the end surface of the horizontal structural member. The coupling plate includes a plurality of coupling holes and first deficient portions. The coupling hole allows insertion of a rod-shaped coupling tool within the groove. The coupling tool passes through the horizontal structural member. The first deficient portion is formed by cutting out the peripheral area of the coupling hole. The first deficient portion is formed in an arc shape centered at the coupling hole.

Diagonal beam joining hardware according to one or more embodiments includes: a beam splicing part; an extending part protruding from an appropriate intermediate part of the beam splicing part; and a beam receiving hardware mounting part bending and extending from an end edge of the extending part to form a predetermined plane angle with respect to the beam splicing part. The beam splicing part is attached and fastened to a side face of a continued beam by through bolts and penetrating the beam in the beam width direction. Beam receiving hardware is fitted in a slit formed in an end part of the diagonal beam. A contacting part of the beam receiving hardware is superimposed on the beam receiving hardware mounting part of the diagonal beam joining hardware and fastened by bolt/nut fastening.

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 connector referred to herein as a knife plate, and the structural connections formed using the knife plate. The knife plate may have a first portion configured to affix to a first structural member, such as a vertical column. The knife plate may have a second portion configured to fit within a slot formed in a second structural member, such as a horizontal beam. The second structural member may be pinned to the knife plate using one or more dowels fit through the second structural member and the knife plate.

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.

Apparatus for interconnecting wooden members that includes a V shaped pair of flanges that are fixed to an L shaped bracket which bracket is adapted to be attached to one wooden member and where the flanges are adapted to be inserted into V slots on a second wooden member.

A building includes a floor located between an upper floor and a lower floor. The floor includes first floor extending members and second floor extending members that intersect the first floor extending members. The first floor extending members and the second floor extending members are made of wood. A reinforcement member is arranged in at least one of a section between two of the first floor extending members and a section between two of the second floor extending members.

Wood connection for large wooden constructions comprising a first wood module, a second wood module and a perforated steel plate comprising a plurality of holes, where the first wood module and the second wood module comprises a plurality of laminated wood layers, where each wood layer comprises a plurality of laminated veneer plies, where a first part of the perforated steel plate is mounted in the first wood module with glue, and where a second part of the perforated steel plate is mounted in the second wood module with glue, with a centreline of the perforated steel plate aligned with a split line between the first wood module and the second wood module, and where the perforated steel plate has a tensile strength exceeding 700 MPa and that a wood module is at least 6 cm thick and has a tensile strength exceeding 20 MPa.

Installation and construction methods for installing a wall panel are provided. The wall panel includes a surface member and a long joint member that extends horizontally, is fixed to one plate surface of the surface member, and is joined to a pair of wooden columns. The method includes: disposing the joint member between the pair of wooden columns; joining both longitudinal ends of the joint member to respective side surfaces, facing each other, of the pair of wooden columns; installing the wooden beam between the pair of wooden columns and adjusting erection of the wooden columns; and fixing an edge of the surface member to front surfaces of the pair of wooden columns and the wooden beam.
