Description

  The present invention relates to a metal joint for joining shaft members such as columns and horizontal members in a wooden frame building, for example.

  As a joint metal fitting, what was indicated by the following patent documents 1 is known.

  The metal joint is formed of a single metal plate in a U-shape in plan view, and is a pair of vertically long rectangular plate-shaped column mounting parts that are attached to the side surfaces of the column, and a pair that extends in parallel from the left and right sides of the column mounting part pieces. It has a horizontal member attachment part piece. A through hole through which the tightening bolt is inserted is formed in the column attaching part piece, and a through hole through which the drift pin is inserted is formed in the horizontal member attaching part piece. In the joint hardware, after the column member mounting portion piece is fixed to the column with the fastening bolt, the end portion of the horizontal member is fixed to the horizontal member mounting piece portion using a drift pin.

  In the joint hardware having such a configuration, the load applied to the horizontal member attaching part piece is supported by the pillar attaching part piece. As described above, the column attaching part piece is a part made of a single plate material. And is fixed to the side of the column with tightening bolts. For this reason, when a relative displacement occurs between a column and a horizontal member due to a strong load, for example, the load concentrates on the through hole or the fastening bolt portion, and there is a possibility that the joint hardware is broken or dropped off.

  The main object of the present invention is to increase the fixing strength by effectively dispersing the load.

Means for that are provided on the base part attached to the end in the longitudinal direction of the shaft member equivalent to the wire member constituting the wooden frame building, and on the contact surface contacting the end surface of the shaft member in the base part, An insertion portion extending in the longitudinal direction of the shaft member is provided, and at least one of an insertion hole for inserting a separate attachment member into the base portion or a screw hole for screwing the attachment member is provided, and the base portion is the insertion portion. A plurality of support plates disposed with a gap along the longitudinal direction of the portion, and a spacing holding portion that extends from the insertion portion and that holds the spacing between the support plates integrally with the insertion portion In this case, the cylindrical member having the insertion hole or the screw hole therein is integrally provided in the spaced holding portion in a state of being sandwiched between the support plates .

  In this configuration, since the plurality of support plates constituting the base portion are separated and held by the separation holding portion integral with the insertion portion, when a load is applied to the base portion, the load is distributed through the plurality of support plates.

  In the present invention, a plurality of contact points can be provided by providing a plurality of support plates in the base, and the load is distributed through these contact points, so that the fixing strength of the joint hardware can be increased. Since the fixing strength can be increased, the joint hardware can be reduced in size and simplified as compared with a joint hardware having the same fixing strength.

  The metal joint of the present invention is used for joining shaft members for constructing a wooden frame building, and is attached to the end in the longitudinal direction of the shaft member equivalent to the wire member constituting the wooden frame building. A base portion to be attached and an insertion portion provided on a contact surface that contacts the end surface of the shaft member in the base portion and extending in the longitudinal direction of the shaft member are provided. The form of the base of the joint hardware, the number of insertion parts, and the like are appropriately set according to the application location.

  In addition to the linear members such as columns, beams, and foundations that make up the shaft assembly, the above-mentioned shaft material is a member that has the same material, cross-sectional shape, and size as that of such a linear member, and one of the vertical and horizontal shapes in the cross-sectional shape. Are members having strength equivalent to that of a wire member, such as members having the same size and the other having the same size. Here, the wire member constituting the shaft assembly and other equivalent members are collectively referred to as a shaft member.

  An embodiment for carrying out the present invention will be described below with reference to the drawings.

  The metal joint 11 shown in FIG. 1 is suitable for joining the end face of another shaft material to the side surface of the shaft material, and is a drawing metal fitting 11a that is attracted to the opposing portion.

  FIG. 2 is a front view showing an example of a building panel 51 using the draw-joint hardware 11a. The draw-joint hardware 11a is built in a state where the whole is embedded in the end portion of the shaft member, and is used for joining the shaft member.

  First, the building panel 51 will be described, and then the draw-in joint hardware 11a will be described.

  The building panel 51 shown in FIG. 2 is for constituting a wooden frame building, and more specifically, used as a load bearing panel that can constitute a load bearing wall when a wooden frame building is constructed. Is. The building panel 51 supports an outer peripheral frame 52 positioned on the outer periphery of the building panel 51, a horizontal reinforcing portion 53 extending in the horizontal direction inside the outer peripheral frame 52, and a horizontal reinforcing portion 53 inside the outer peripheral frame 52. A vertical reinforcing portion 54 is provided.

  The horizontal reinforcing portion 53 includes a horizontal shaft member 55 made of a shaft member equivalent to the wire member 81 (see FIG. 3) constituting the shaft member of the wooden frame building, and extends horizontally, and the horizontal shaft member 55 and the outer frame 52. It is comprised with the face material 56 hold | maintained between opposing parts. The vertical reinforcing portion 54 is made of a shaft material equivalent to the wire member 81 (see FIG. 3) constituting the shaft set and extends vertically, and between the vertical material 57 and the facing portion of the outer peripheral frame 52. It is comprised by the face material 58 hold | maintained.

  This building panel 51 is a frame panel 51a in which the outer peripheral frame 52 is made of a frame material 59 that is thinner than the wire member 81 that constitutes the shaft assembly, and the outer frame 52 is fitted between the line members 81 that constitute the shaft assembly. (See FIGS. 3 and 4). The frame member 59 has a thickness that is less than or equal to half that of the wire member 81. Specifically, one of the vertical and horizontal cross-sectional shapes is the same, and the other is less than half the size. As a numerical value, when the line member 81 is 105 mm in length and width, the cross-sectional shape of the frame member 59 is set to 105 mm in length and the width is set to about 27 mm, for example.

  As an example of the building panel 51, the outer peripheral frame 52 in the frame panel 51 a shown in FIG. 2 is composed of four frame members 59. These frame members 59 are two vertical frame members 59a that extend vertically at both left and right positions, an upper frame member 59b that extends left and right above, and a lower frame member 59c that extends left and right below. The frame member 59 of the frame panel 51a is fixed with the end portions in the longitudinal direction overlapping each other.

  The horizontal reinforcing portion 53 includes the above-described horizontal shaft member 55 extending in parallel with the upper frame member 59b at the upper position of the vertical frame member 59a, and the above-described surface held between the horizontal shaft member 55 and the upper frame member 59b. It consists of a material 56 and a bundle material 61 that connects the horizontal shaft material 55 and the upper frame material 59b in the middle in the longitudinal direction. The length of the horizontal shaft member 55 is the length spanned between the vertical frame members 59a, and the horizontal reinforcing portion 53 is formed over the entire width in the outer peripheral frame 52.

  The cross-sectional shape and the size of the bundle material 61 are the same as those of the horizontal shaft material 55. The number and interval of the bundle members 61 provided are appropriately set according to the length of the horizontal shaft member 55. The height of the horizontal reinforcing portion 53, that is, the interval between the upper frame member 59b and the horizontal shaft member 55 can be set as appropriate.

  A groove (not shown) for fitting the outer peripheral edge of the face member 56 is formed at an intermediate position in the depth direction on the inner peripheral side surfaces of the left and right vertical frame members 59a and the upper frame member 59b. A structural plywood can be used for the face material 56, and the thickness of the face material 56 is a thickness that fits on the inner peripheral surface, and is preferably set to about 9 mm with respect to the inner surface of 105 mm, for example.

  On the outer peripheral edge of the face material 56 facing both the left and right side surfaces of the bundle material 61 and the upper surface of the horizontal shaft material 55, contact surface portions 56a that contact these are formed. In other words, the size of the face material 56 is such that the outer peripheral edge facing the upper frame material 59b and the vertical frame material 59a fits in the groove, and the end face facing the left and right side surfaces of the bundle material 61 and the upper surface of the horizontal shaft material 55. Is set to a size in contact with these. The holding of the face material 56 to the bundle material 61 and the horizontal shaft material 55 is performed by a sandwiching material 62 that sandwiches both the front and back surfaces of the face material 56. That is, the abutting surface portion 56 a is clamped by the clamping material 62 and the clamping material 62 is fixed to the bundle material 61 and the horizontal shaft material 55. The clamping member 62 is fixed by a nail, a screw or the like (not shown).

  A bolt 63 is inserted in a skewered state from the upper frame member 59b to the horizontal shaft member 55 in a portion corresponding to the center in the cross-sectional shape of the bundle member 61, and the upper frame member 59b, the bundle member 61, and the horizontal shaft member 55 are coupled. It is integrated.

  In the horizontal reinforcing portion 53, the above-described attracting joint 11 a that is attracted to the vertical frame material 59 a that is the opposite portion is built in both ends of the horizontal shaft member 55 in the longitudinal direction.

  The vertical reinforcing portion 54 supports the horizontal reinforcing portion 53 from below, and is formed on one side in the left-right direction of the frame panel 51a. Specifically, the vertical reinforcing portion 54 in FIG. 2 is formed on the left side of the drawing, and extends in parallel with the vertical frame member 59a, and the vertical axis member 57 interposed between the horizontal shaft member 55 and the lower frame member 59c. The surface material 58 is held between the vertical axis member 57 and the vertical frame member 59a. The vertical reinforcing portion 54 can also be constituted by the longitudinal axis member 57 alone. Since the basic configuration of the vertical reinforcing portion 54 is the same as that of the horizontal reinforcing portion 53, detailed description thereof is omitted. The width of the vertical reinforcing portion 54, that is, the interval between the vertical frame member 59 a and the vertical axis member 57 can be set as appropriate, as in the case of the horizontal reinforcing portion 53.

  However, since the longitudinal direction of the horizontal reinforcement portion 53 is the horizontal direction, whereas the longitudinal direction of the vertical reinforcement portion 54 is the vertical direction, a penetrating material 64 is provided instead of the bundle member 61 of the horizontal reinforcement portion 53. ing. The structure of the penetrating material 64 is the same as that of the bundle material 61 except that the name and direction are different. In the example of FIG. 2, bolts are not drawn, but the vertical frame member 59a, the penetrating member 64, and the longitudinal member 57 may be integrated using bolts (not shown). In the figure, 65 is a sandwiching material.

  Similarly to the case of the horizontal shaft member 55 of the horizontal reinforcing portion 53, the above-described attracted joint metal 11 a that is attracted to the facing portion is also built in the end of the vertical member 57. Among these drawing joints 11a, a bolt 66 inserted into the horizontal shaft member 55 is screwed into the drawing joint 11a built in the side in contact with the horizontal shaft member 55, and the vertical shaft member 57 and the horizontal shaft member 55 are screwed together. Are fixed in an orthogonal state.

  Moreover, the frame panel 51a of FIG. 2 has the opening part 67 in the intermediate part of the up-down direction (vertical direction). Horizontal members 68 extending in the horizontal direction are installed at the upper end position and the lower end position of the opening forming position for forming the opening 67. Between the horizontal member 68 at the upper end position and the horizontal shaft member 55, and between the horizontal member 68 at the lower end position and the lower lower frame member 59c, a vertical column member 69 is provided as appropriate.

  Further, reinforcing members 70 are fixed to the four corners of the square formed by the horizontal shaft member 55, the vertical shaft member 57, the vertical frame member 59a, and the lower frame member 59c as necessary. The reinforcing member 70 is fixed to the inner surface of the horizontal shaft member 55, the vertical member 57, the vertical frame member 59a or the lower frame member 59c and is assembled at right angles to each other, and the surface direction of the substrate 70a. It is composed of an angle holding member 70b that spreads in the orthogonal direction and is fixed between the inner side surfaces of the substrate 70a. The angle holding member 70b has a right-angled portion that forms a right angle, and the right-angled portion is fixed to a joint portion between the substrates 70a.

  It continues and demonstrates the above-mentioned attracting | attaching metal fitting 11a. The attracting metal fitting 11a is attracted to the facing portion as described above, and FIG. 5 shows an exploded perspective view thereof.

  As shown in FIGS. 1 and 5, the draw-joint hardware 11 a includes a base 12 attached to the longitudinal end of the horizontal shaft member 55 and the vertical member 57, and the horizontal shaft member 55 and the vertical member 57 of the base member 12. The insertion portion 13 is provided on the abutting surface 12 a that abuts the end surface of the horizontal axis member 55 and extends in the longitudinal direction of the horizontal axis member 55 and the vertical axis member 57. The base 12 is provided with an insertion hole for inserting a separate attachment member and a screw hole for screwing the attachment member. An attachment member is a member attached according to the objective, and there exist a bolt etc. for a coupling as an attachment member, for example. In addition, the base 12 includes a plurality of support plates 14 disposed with a gap along the longitudinal direction of the insertion portion 13, and a support plate that extends from the insertion portion 13 and is integrated with the insertion portion 13. It is configured by a separation holding portion 15 that holds and keeps 14 apart.

  Specifically, the insertion part 13 and the separation holding part 15 of the drawing joint 11a are constituted by a single metal plate 16, and the insertion part 13 fits inside the horizontal shaft member 55 or the vertical member 57. It is a plate shape that is appropriately shaped in size. In the example shown in FIGS. 1, 5, and 6, the insertion portion 13 has a substantially triangular shape. The insertion portion 13 is formed with a through hole 13a for inserting a drift pin 17 (see FIG. 6) for coupling with the horizontal shaft member 55 and the vertical shaft member 57. The number and arrangement of the through holes 13 a are appropriately set according to the shape and size of the insertion portion 13. In addition, the insertion part 13 may be three-dimensional shapes, such as a cylinder shape, instead of the plate shape as mentioned above.

  A cutout portion 13 b that enters from the end of the separation holding portion 15 is formed at a central position in a portion of the insertion portion 13 that is close to the separation holding portion 15. The notch 13b is a part for allowing the attachment member to exist, and the shape of the notch 13b is appropriately set. The cutout portion 13b shown in FIGS. 1, 2, 5, and 6 has a semi-oval shape.

  The separation holding part 15 integrated with the insertion part 13 has two step parts 15a and 15b formed on the outer edge. Inside, there is a nut holding space 15c that holds the nut 18 continuously from the notch 13b. The nut 18 is a member for providing the aforementioned screw hole, and the screw hole 18 a inside the nut 18 becomes the screw hole 12 b of the base 12.

  The support plates 14 constituting the base portion 12 are the same two as the number of the step portions 15a and 15b described above, and the shape of the support plate 14 is a rectangular plate shape. The size of the contact surface 12 a of the base portion 12, in other words, the size of the support plate 14 is formed smaller than the cross-sectional shape of the horizontal shaft member 55 and the vertical member 57. Specifically, the length of the long side of the support plate 14 is the same as the length of the corresponding portion of the horizontal axis member 55 or the vertical axis member 57, and the length of the short side is the horizontal axis member 55 or the vertical axis member 57. Shorter than the length of the corresponding part. The two support plates 14 are positioned on the side close to the insertion portion 13 and are disposed on the outermost side of the one support plate 14a having the abutting surface 12a and the horizontal shaft member 55 or the vertical member 57. This is the other support plate 14b that is positioned flush with the outer end faces 55a, 57a that are positioned or slightly deeper than the same level.

  A through hole 19 corresponding to the screw hole 18a of the nut 18 is formed at the center of the one support plate 14a and the other support plate 14b, and is located outside the through hole 19 and along the long side. A slit-like insertion groove 20 having a size to fit the step portions 15a and 15b is formed at both positions. The insertion groove 20 of one support plate 14a is formed longer than the insertion groove 20 of the other support plate 14b by the stepped portions 15a and 15b.

  The screw hole 18a of the nut 18 becomes the aforementioned screw hole 12b in the base portion 12, and the through hole 19 formed in each of the support plates 14a and 14b becomes the aforementioned insertion hole 12c in the base portion 12.

  The size of the base 12 provided with the support plate 14 is set to a size that is embedded so as not to be displaced relative to the longitudinal ends of the horizontal shaft member 55 and the vertical member 57. That is, as shown in FIG. 7 which is a plan view of the end portions of the horizontal shaft member 55 and the vertical shaft member 57 incorporating the attracting joint 11a, the base 12 is located at the end portions of the horizontal shaft member 55 and the vertical member 57. It is a size corresponding to fitting to the formed seat carved portions 55b and 57b. In other words, the width of the support plate 14 is a size corresponding to the width of the seat carved portions 55b and 57b.

  Inner end surfaces 55c and 57c parallel to the outer end surfaces 55a and 57a are formed inside the seat carved portions 55b and 57b, and the inner end surfaces 55c and 57c are the contact surfaces 12a of the base portion 12, that is, one of them. It is an end surface which the surface by the side of the insertion part 13 of the support plate 14a contacts. The outer edges of the two support plates 14a and 14b arranged in parallel are in contact with the inner side surfaces of the seat carved portions 55b and 57b.

  The metal plate 16a having the insertion portion 13 and the separation holding portion 15, the nut 18, and the two support plates 14 are combined and integrated by welding or the like.

  As shown in FIG. 8, the draw-joint metal part 11 a may be provided with only the insertion hole 12 c in the base part 12 by fixing the tubular member 21 as shown in FIG. 8. Although not shown, the support plate 14 can also be provided with screw holes to form the base 12 having only screw holes.

  The draw joint 11a configured as described above is fitted into the recessed portions 55b and 57b at the ends of the horizontal shaft member 55 and the vertical member 57, for example, and then the drift pin is inserted into the through hole 13a of the insertion portion 13. 17 is inserted and fixed to the horizontal shaft member 55 and the vertical member 57 (see FIG. 7), and then a bolt 66 is screwed into the screw hole 12b of the drawing joint 11a in the horizontal shaft member 55 or the vertical member 57. The horizontal shaft member 55 and the vertical member 57 are joined together. The joining procedure may be reversed from the above.

  Then, as shown in FIG. 9, the end portions of the horizontal shaft member 55 and the vertical shaft member 57 are attracted toward the frame member 59 and the horizontal shaft member 55 through which the bolts 66 are inserted.

  In such a joined state, the two support plates 14 constituting the base portion 12 are separated and held by the separation holding portion 15 integral with the insertion portion 13, and the load applied to the base portion 12 is passed through the separation holding portion 15. The two support plates 14 are dispersed. In addition, since the two support plates 14 are held at a distance by the spacing and holding portion 15, the load can be distributed well.

  For this reason, it can suppress that an excessive load is applied locally and can raise the fixed intensity | strength of the attracting | attaching metal fitting 11a. In addition, since the fixing strength can be increased, it is possible to reduce the size and simplification of the attracting joint 11a as compared with the joint having the same fixing strength. Further, the drawing joint 11a that can be reduced in size is configured so as to be entirely embedded in the horizontal shaft member 55 and the vertical member 57, and therefore can be concealed in the horizontal shaft member 55 and the vertical member 57. .

  In the frame panel 51a as the building panel 51 having the above-described configuration, the horizontal reinforcing portion 53 provided at the upper end portion exhibits the resistance to shearing and bending by the horizontal shaft member 55 and the face member 56, and the vertical reinforcing portion 54 is provided. Supports the horizontal reinforcing portion 53 and reduces the burden on the pillar. For this reason, when a wooden frame building is constructed, a high strength bearing wall can be formed. Since the horizontal axis member 55 and the vertical axis member 57 of such a useful frame panel 51a are joined by the draw joint 11a having a high fixed strength as described above, the frame panel 51a can be improved.

  The draw joint 11a described above is a shaft member (horizontal shaft member 55, vertical member 57) of the frame panel 51a as the building panel 51 in which the outer peripheral frame 52 is composed of the frame member 59 having a strength lower than that of the wire member 81. Although it is suitable for joining, it can also be used for joining the wire members 81 of the shaft set.

  Thus, other than the formation of the building panel 51, another example of the joint hardware 11 that can be suitably used for joining the wire members 81 of the shaft group will be described below. Next, one metal joint 11 described below can connect three or more shaft members.

  10 and 11 are perspective views of the metal joint 11. In the formation of the building panel 51, the metal joint 11 is used to form the shaft panel 51b as shown in FIG. The shaft panel 51b is a shaft panel 51b provided with a shaft member 71 having a strength corresponding to that of the wire member 81 as the outer peripheral frame 52 described above, and the joint metal 11 is a corner joint metal provided at a corner of the shaft panel 51b. 11b.

  The shaft panel 51b has a configuration in which the outer peripheral frame 52 is composed of a shaft member 71 equivalent to the wire member 81 constituting the shaft assembly, and the outer peripheral frame 52 is assembled as the line member 81 constituting the shaft assembly (FIG. 13, FIG. 14). That is, the shaft 71 becomes a line member 81 of the wooden frame building when the wooden frame building is constructed. The shaft member 71 has the same thickness as the wire member 81. Specifically, the cross-sectional shape has the same vertical and horizontal sizes, or one of the vertical and horizontal sides is the same and the other has the same size. In terms of numerical values, when the linear member 81 used as a pillar or foundation is 105 mm in length and width and the linear member used as a beam is 120 mm × 105 mm in length and width, the cross-sectional shape of the shaft member 71 is set to 105 mm in length and width.

  When the outer peripheral frame 52 in the shaft panel 51b of FIG. 13 is formed all around in advance, the outer peripheral frame 52 is constituted by four shaft members 71 and four corner joint metal fittings 11b. In other words, the shaft panel 51b is provided with at least one member of the four shaft members 71 and the four corner joint metal fittings 11b on the outer periphery in advance. When the outer peripheral frame 52 is not formed on the entire periphery from the beginning, the shaft member 71 and the corner metal fitting 11b are disposed so as to complement each other between the adjacent shaft panels 51b.

  The four shaft members 71 are two longitudinal members 71a extending vertically at both left and right positions, an upper shaft member 71b extending left and right above, and a lower shaft member 71c extending left and right below. Each shaft member 71 is set to such a length that the corners of the end portions are in contact with each other and the end portions do not overlap each other. The corner metal fitting 11b joins the end faces forming a right angle of the shaft member 71 so as to fill the corner generated by the shaft member 71 having the length as described above. The corner joint hardware 11b also has a function of joining adjacent shaft panels 51b.

  The shaft panel 51b in FIG. 12 has the same configuration as the frame panel 51a in FIG. 2 except for the thickness of the outer peripheral frame 52. That is, the configuration of the portion surrounded by the outer peripheral frame 52 in the shaft panel 51b in FIG. 12 is the same as that of the frame panel 51a in FIG.

  Strictly speaking, the shaft panel 51b illustrated in FIG. 12 has a configuration in which the frame panel 51a of FIG. 2 is surrounded by the outer peripheral frame 52 including the shaft member 71, including the outer peripheral frame 52. That is, it can be said that the outer peripheral frame 52 of the shaft panel 51b includes the frame material 59 of the frame panel 51a, in other words, the frame material 59 and the shaft material 71 are overlapped. However, the outer peripheral frame 52 of the shaft panel 51b can be configured without the frame member 59. In other words, the outer peripheral frame 52 made of the shaft material 71 may be composed of only the shaft material 71 in addition to the shaft material 71 and the frame material 59.

  In the description of the shaft panel 51b in FIG. 12, the same parts as those in the frame panel 51a in FIG.

  Next, the corner joint hardware 11b will be described.

  The corner metal fitting 11b is the same as the above-described pulling metal fitting 11a, and is attached to the end portion of the shaft member 71 in the base portion 12 and the base portion 12 attached to the end of the shaft member 71 in the longitudinal direction. The insertion portion 13 is provided on the abutting surface 12 a that abuts and extends in the longitudinal direction of the shaft member 71. The base 12 is provided with an insertion hole for inserting a separate attachment member or a screw hole for screwing the attachment member. The attachment member is a member attached according to the purpose, and examples of the attachment member include a bolt for connection, a column base member for support, and a suspension member for suspension. In addition, the base 12 includes a plurality of support plates 14 disposed with a gap along the longitudinal direction of the insertion portion 13, and a support plate that extends from the insertion portion 13 and is integrated with the insertion portion 13. It is configured by a separation holding portion 15 that holds and keeps 14 apart.

  In particular, the abutting surface 12a of the base portion 12 is abutted against and fixed to the outermost end surface 71e in the longitudinal direction of the shaft member 71 to be the wire member 81 of the shaft assembly. As shown in the perspective views of FIGS. 10 and 11, the base 12 of the corner metal fitting 11 b is a hexahedron that forms a cube or a rectangular parallelepiped as a whole. FIG. 15 is an exploded perspective view of the corner metal fitting 11b, and FIG. 16 is a sectional view taken along line AA in FIG.

  The corner joint hardware 11b in which the base portion 12 is a hexahedron may have one to six contact surfaces 12a depending on a portion to be used.
