Description

[0001]
[Industrial application fields]
The present invention relates to a wood joining device and a wood joining metal fitting for a wooden building, which are used to join horizontal members such as columns and beams or horizontal members such as beams and beams to each other.
[0002]
[Prior art]
For example, as described in Japanese Utility Model Laid-Open No. 7-19409, an attachment piece is provided at one end of a flat joint substrate provided with a through hole for penetrating a support rod, and the other end is outside the thickness of the joint substrate. There is a structure using a joint fitting in which cylindrical locking pieces having a large diameter are connected in series, and a support piece continuous to the attachment piece is provided at the lower end of the joint substrate.
[0003]
In this conventional example, the attachment piece is attached to a pillar or beam, and the joining substrate and the engaging piece are inserted into a cut groove provided in a horizontal member such as a beam to be joined to the pillar or the beam. The locking member piece is brought into pressure contact with the horizontal member, and the horizontal member is drawn to the pillar or beam, and the horizontal member is supported by the support member, that is, supported on the lower surface of the horizontal member. The column or beam and the horizontal member are joined so as to apply a piece.
[0004]
[Problems to be solved by the invention]
In the conventional example, a locking part piece that is inclined in a vertical hole (back end part of the cut groove) provided in the horizontal member is fitted, and along the hole in the inclined edge of the locking part piece. The horizontal member is drawn in the column direction by movement, but the amount of drawing is determined by the inclination angle of the locking piece, so when you need something with different drawing amount It is necessary to prepare different types of metal fittings and to make the above-mentioned hole formed on the horizontal member side corresponding to the inclination angle long in the cross-sectional shape (long hole). The strength of the material will be weakened.
[0005]
In addition, the conventional example is structured so that the support piece is brought into contact with the lower surface of the horizontal member. Therefore, the height width is required to arrange the bonding substrate at an appropriate position in the height direction of the horizontal member. It is necessary to prepare joint fittings corresponding to different horizontal members. In other words, since the positional relationship of the horizontal member is determined by the presence of the support piece, the higher the width of the horizontal member, the higher the width of the horizontal member must be. Therefore, it is necessary to prepare a joining metal fitting corresponding to horizontal members having different heights and widths.
[0006]
[Means for Solving the Problems]
As a means to cope with the above-mentioned drawbacks of the conventional example that occurs when the pulling amount must be different, a cut groove formed vertically on the end face of one piece of wood to be joined to the other side face of the other piece of wood The free end side of the flat plate-like bonded substrate is engaged, a recessed notch is formed at the upper end of the bonded substrate, and the pressing piece that press-contacts the side edge of the recessed notch on the free end side is Engage with the groove and pivotally attach to the one piece of wood so that it can be rotated from the outside. The operation piece connected to the pressing piece protrudes into the upper part of the piece of wood through the cut groove. In addition, as a means to handle horizontal members with different heights and widths, the amount of drawing can be set freely, and it engages with a notch groove vertically formed on the end face of one piece of wood to be joined together To the base end side of the flat plate-shaped bonded substrate, the attachment piece that is fixed to the side surface of the other wood, In addition, a screw cylinder for screwing a fixing bolt for locking the head to the lower end of the one piece of wood is connected to the lower end portion on the free end side, and the other one piece of wood is placed at an appropriate position of the joining substrate. A through-hole for penetrating the support rod through, and at the upper end thereof, a free end side of the bonded substrate by a pressing piece engaged with the cut groove and pivotally attached to the outside of the one wood The wood joining metal fittings having a structure in which a recessed notch to which the side edge is pressed are respectively formed are used.
