Description

  The present invention relates to a wood joining device and a wood joining metal fitting for a wooden building, which are used for joining horizontal members such as columns and beams or horizontal members such as beams and beams to each other.

  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 joining metal fitting formed by connecting cylindrical locking pieces having large diameters and providing a support piece continuous to the attachment piece at the lower end of the joining substrate.

  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 so that the horizontal member is drawn to a column or beam and the horizontal member is supported by the support member, that is, the supporting member piece is supported on the lower surface of the horizontal member. The column or beam and the horizontal member are joined so as to be applied.

  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.

  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.

  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 for dealing with horizontal members with different heights and widths, the amount of drawing can be set freely, and it engages with a cut groove formed vertically on the end surface of one piece of wood to be joined together A flat joint substrate to be engaged, and a side edge on the free end side of the joint substrate engaged with the joint substrate A wooden joint metal fitting for a wooden building having a pressing piece to be pressed, wherein the bonding substrate has an attachment piece fixed to a side surface of the other wood on the base end side, and a free end side A screw cylinder for screwing a fixing bolt that locks the head to the lower end of the one piece of wood is connected to the lower end portion, and a support rod is passed through the other piece of wood at an appropriate position of the joining substrate. A through hole is provided, and a concave notch is formed at an upper end thereof, and the pressing piece is pivotally attached to the cut groove so as to be rotatable from the outside of the one of the woods. A wood joining bracket having a structure in which the side edge on the free end side of the joint substrate is pressed by rotation while engaging with the recess notch formed at the upper end is used.

Further, the cut groove is formed with first and second inner surfaces in which both planes of the bonded substrate are close to each other, and the operation part piece starts to be immersed in the upper side of one wood through the cut groove. In addition, a protruding portion is provided so that the tip of the first inner surface is locked to at least one of the first and second inner surfaces.
Then, the pressing piece is provided with an operation part piece, and the operation part piece is protruded so as to be immersible above one of the woods through the cut groove.

Furthermore, the wood joining bracket 1 has a pressing piece 2 that engages with the joining substrate 3 and presses the side edge on the free end side of the joining substrate 3.

  The reason that the screw cylinder 6 is inclined so as to gradually open upward with respect to the other one wood 24 is that the one wood 20 is lowered in the cut groove 21 along the bonding substrate 1. This is because the cut groove 21 is in contact with the inclined edge of the screw cylinder 6 and is automatically brought close to the other one of the timbers 24, that is, the drawing operation is performed.

  The joint substrate 3 is provided with an arc-shaped concave notch 7 at the upper end thereof, and through holes 9, 9, 9 for insertion of the support rods 8 so as to be positioned immediately below the concave notch 7, The mounting piece 4 is formed by providing an L-shaped piece 4b from the free end side to the lower end side of the piece 4a partially extended from the bonding substrate 3, and the fastening bolt 10 is inserted into the L-shaped piece 4b. The through-hole 11 is provided.

  The engagement part piece 5 is positioned directly below the part piece 4a of the attachment part piece 4 and is arranged in a crossing direction with respect to the joint substrate 4 in the same manner as the L-shaped part piece 4b. It is the one that was installed.

  The engagement piece 5 is engaged with the second engagement recess 26 when the fitting 1 is fastened to the other piece of wood 24 with the fastening bolt 10 in the attachment piece 4. This prevents falling and prevents rotation associated with the tightening operation on the bonding substrate 3 side.

  The pressing piece 2 is engaged with the cut groove 21 so as to be pivotable from the outside of one of the timbers 20, and is engaged with a recessed notch 7 formed at the upper end of the bonded substrate 3 by rotating. The side edge on the free end side of the bonding substrate 3 is pressed. Specifically, the pressing piece 2 is formed of a deformed circular ring body having a through-hole 13 for penetrating the support shaft 12, and at one end thereof, a first hitting portion 14a protruding in the vertical direction and a horizontal direction. The operation part piece 14 provided with the protruding 2nd hit | damage part 14b protrudes and is comprised.

  In the figure, reference numeral 20 denotes one piece of wood to be joined to each other (horizontal members such as girders and beams in the embodiment), and a cut groove 21 is provided vertically in the center of the end face 20 'of the wood 20, while this cut A first through hole 22 that coincides with the through hole 13 in a direction intersecting with the groove 21, and a second through hole 23 that is directly below the first through hole 22 and corresponds to the through holes 9, 9, 9. , 23, 23, and the pressing piece 2 is inserted into the cutting groove 21 of the one wood 20 provided with the cutting groove 21 and the first and second through holes 22, 23. The two through-holes 13 and the first through-holes 22 are made to coincide with each other, and the support shaft 12 is inserted through them so that the pressing piece 2 is assembled to one wood 20.

  A first engaging recess is formed on a side surface 24 'of the other wood 24 (which is a column in the embodiment, but may be a horizontal member such as a beam) opposite to the end surface 20'. 25 and the second engagement recess 26, the first engagement recess 25 is formed with a through hole 15 penetrating the other wood 24, and the attachment piece 4 is provided in the first engagement recess 25. Further, the engagement piece 5 is engaged with the second engagement recess 26, respectively, provided on the L-shaped piece 4 b of the attachment piece 4, and the tightening bolt from the through-hole 11 side that coincides with the through-hole 15. 10, and a wood nut 1 is attached by screwing a fastening nut onto the tip of a fastening bolt 10 protruding from a side surface (not shown) opposite to the side surface 24 ′ of the other wood 24. Is protruded from the side surface 24 ′ of one of the timbers 24.

  When the one wood 20 is combined with the other one wood 24 and the free end side of the joining substrate 3 projecting from the other wood 24 so as to engage with the cut groove 21, it is preset. As described above, the pressing piece 2 engages with the recessed notch 7 provided on the bonding substrate 3, and one wood 20 is moved through the support shaft 12 and the wood joining fitting 1 by the contact of the pressing piece 2 with the recessed notch 7. In this state, the operation part piece 14 protruding from the cut groove 21 is struck with a tool by the first tapping part 14a and the second tapping part 14b. When the operation piece 14 is rotated around the support shaft 12 in the clockwise direction, that is, in the direction close to the other wood 24, the pressing piece 2 provided with the operation piece 14 is centered on the support shaft 12. The joint of the concave notch 7 formed by turning and having a peripheral edge formed on the joint substrate 3 The side edge 7 ′ on the free end side of the plate 3 is pressed, and as a result, one of the timbers 20 is gradually drawn toward the other timber 24, and the immersion of the operation piece 14 into the cut groove 21 is completed. Sometimes the drawing operation of one wood 20 is completed, and at this time, the second through holes 23, 23, 23 formed on the side of the one wood 20 at the positions of the through holes 9, 9, 9 formed in the bonding substrate 3 are completed. Are moved, and the support rods 8 are passed through them, and when the fixing bolts 28 are screwed into the screw holes 6a of the screw cylinder 6 through the washers 27 from the lower surface side of one of the woods 20 and tightened, the support rods are 8, the head 28 ′ of the fixing bolt 28 partially receives the weight of the one wood 20 through the washer 27, and the joining operation of the both woods 20 and 24 through the wood joining fitting 1 is completed.

  In the figure, reference numeral 18 denotes an engaging portion of a screw cylinder 6 formed by communicating with one wood 20 through a notch groove 21, and the screw cylinder 6 is press-contacted to the inner edge of the engaging portion 18 so that one wood as described above. 20 is drawn toward the other side of the wood 24.

  The reason why the upper edges 7 ", 7" on the upper end side of the opening of the concave notch 7 are inclined is to make the pressing piece 2 easily engage with the engaging notch 7 (becomes a guide edge). .

  Further, the processing and formation of the cut groove 21 or the like for one piece of wood 20 or the first engaging recess or the like for the other piece of wood 24 is performed in a relative relationship with the wood joining bracket 1 or both pieces of wood 20 and 24. .

  In FIG. 1 and FIG. 2, there is a gap between one wood 20 and the other wood 24, but this is for ease of explanation in the explanation of the present invention. In practice, the two timbers 20, 24 may be in contact with each other, and at that time, the one timber 20 is drawn so as to fit into the other timber 24. The said processing of both materials is performed based on this point.

  Since the present invention is configured as described above, it is possible to reliably perform a pulling operation, to provide an unprecedented novel structure wood joining device, and to be in a pivoted position of a pressing piece that engages in a recessed notch By changing, it is possible to change the drawing amount of one piece of wood toward the other piece of wood.

  Further, the attachment piece 4 is fixed to the side surface 24 ′ of the other wood 24, the free end side of the bonding substrate 3 is engaged with the cut groove 21 provided in the one wood 20, and the other wood 24 is engaged. When the pressing piece 2 pivotally attached to the wood 24 is rotated, the pressing piece 2 presses the side edge of the concave notch 7 on the free end side of the bonding substrate 3, and as a result, one wood 20 is the other wood. 24, when the drawing is completed, the support rods 8, 8, and 8 are respectively passed through the through holes 9, 9, and the fixing bolt 28 is screwed into the screw cylinder 6 and tightened. The wood 20 is firmly and securely supported by the support rods 8, 8, 8 and the fixing bolt 28, and the wood joint 1 that can join the pair of wood 20 in a stable state can be provided.

Next, a wood joining device for a wooden building according to a modification of the present embodiment will be described with reference to FIG. FIG. 4 (a) is a partially cutaway front view of a wood joining device for a wooden building according to a modification of the present invention, and FIG. 4 (b) is a cross-sectional view taken along line 1B-1B of FIG. 4 (a). . In addition, the same component as the component demonstrated in FIG. 1 thru | or FIG. 3 attaches | subjects the same code | symbol in FIG. 4, and the description is abbreviate | omitted.
As shown in FIGS. 4A and 4B, in the wood joining device 1a for a wooden building according to the modification of the present embodiment, the cut groove 21 is the first where both planes of the joining substrate 3 are close to each other. An inner surface 21a and a second inner surface 21b are formed. The wood joining device 1 a includes a wood joining metal fitting 1.
The operation piece 14 has a cylindrical shape that protrudes so that the tip 29a is locked to the first inner surface 21a when the immersion of the upper side of the one wood 20 is started through the cut groove 21. A protrusion 29 is provided.

Specifically, as shown in FIG. 4A, the protruding portion 29 is provided at the intersection of the first hitting portion 14a and the second hitting portion 14b. In addition, if the operation part piece 4 is latched by either the upper end of the 1st inner surface 21a or the 2nd inner surface 21b, the protrusion part 29 will be the 1st hit part 14a and the 2nd hit part other than this. You may provide in any location of the part 14b. In addition, the protrusion 29 is provided so that the tip 29a is locked to the upper end of the second inner surface 21b, and the pair of protrusions 29 are provided at the upper ends of the first inner surface 21a and the second inner surface 21b. You may provide so that both may be latched. Further, the projecting portion 29 may have a conical shape, a truncated cone shape, a polygonal frustum shape, or a polygonal column shape instead of the cylindrical shape.
However, the protruding portion 29 is not a high-rigid material but deforms when the first hitting portion 14a or the second hitting portion 14b is hit, and does not prevent the operation portion piece 14 from entering the cut groove 21. It is composed of a flexible material.
Therefore, the cylindrical protrusion 29 configured in this way can suppress the operation piece 14 from being immersed in the cut groove 21 when the wood 20 is handled alone.
When only the wood 20 is operated, since the joining substrate 3 is not provided, the operation piece 14 easily enters the cut groove 21 when the wood 20 is tilted. It was necessary to tilt the other way. However, there are many inconvenient timbers 20 that cannot be easily tilted, and there is a disadvantage that a thin metal piece or the like must be inserted into the cut groove 21 to push out the operation part piece 14.
Therefore, the protruding portion 29 is provided in the first hitting portion 14a or the second hitting portion 14b so that the tip 29a is locked, that is, caught on the upper surface of the wood 20 immediately before the operation piece 14 is inserted into the cut groove 21. The protrusion 29 was provided to function as a stopper.

When joining the wood 20 and the wood 24 in the wood joining apparatus 1a having such a configuration, first, the free end of the joining substrate 3 is provided with the wood joining metal fitting 1 protruding from the side surface 24 'of the wood 24. The sides are combined so as to engage with the cut groove 21.
Thereafter, the operation piece 14 (shown by a solid line in the figure) in which the second hitting portion 14b is closest to the one wood 20 is attached to the support shaft 12 in the same manner as the wood joining bracket 1 according to the embodiment. In order to rotate counterclockwise (CCW) around the center, the first hitting portion 14a and the second hitting portion 14b are hit with a tool.
At that time, the projecting portion 29 made of a flexible material is easily deformed and immersed in the cut groove 21, so that the ease of joining the wood 20 and the wood 24 is not affected.
In other words, the flexibility of the projecting portion 29 is the degree to which the operation piece 14 is deformed and immerses in the cut groove 21 when the first hitting portion 14a or the second hitting portion 14b is hit with a tool. Need to be flexible.

In this way, by hitting the operation piece 14 (first hitting portion 14a, second hitting portion 14b), the end face 20 'can be surely pulled toward the side face 24'.
As described above, according to the wood joining apparatus 1a, the above inconvenience can be solved, so that it is possible to improve the working efficiency at the time of drawing.
