Description

  The present invention relates to a reinforcing member for a wood joint. Specifically, the reinforcement of the wood joint portion having the first hardware formed in an L shape with a vertical plate having a surface that contacts the outer surface of the column and a horizontal plate having a surface that contacts the outer surface of the beam or beam. The present invention relates to a joining structure of a member and a wood using the reinforcing member.

  Every time a big earthquake occurs, a great deal of attention is focused on the safety and earthquake resistance of new and existing wooden structures. In the wooden construction of the conventional construction method, it is well known that the members are arranged diagonally between the pillars in order to ensure safety and earthquake resistance. However, if the braces are arranged, it becomes difficult to use the walls effectively because it becomes difficult to provide doors and windows on the walls. A cane is known as a method that can use the wall surface somewhat effectively, but a wooden cane is not sufficient as the strength of the joint.

  Therefore, various types of reinforcement hardware have been considered as reinforcement. Here, parts to be attached to join and reinforce the joints of building materials are collectively referred to as “reinforcement hardware”. Reinforcing hardware includes plates, nails, bolts, anchor bolts, etc., and many of them are made of metal, so they are called reinforcing hardware. In FIG. 1 of the following Patent Document 1 and FIG. 1 of the following Patent Document 2, a reinforcing hardware embedded in wood is described. Since it is embedded in wood, the reinforcement hardware does not appear to be exposed, and the design is excellent. However, since the wood processing for embedding the reinforcement hardware into the wood is complicated, the wood processing cannot be performed at the construction site, and there is a problem that the wood must be processed at the factory before the wood is brought into the site. In addition, there is a problem that it cannot be applied to an existing wooden structure because the reinforcement hardware is embedded in wood. Furthermore, since it is better not to expose the reinforcing hardware from the wood, there is a problem that the size is limited and the reinforcing strength is limited.

  As other reinforcing hardware, L-shaped reinforcing hardware is described in FIG. 3 of Patent Document 3 below and FIG. 2 of Patent Document 4 below. In either case, the reinforcing hardware is fixed to the outer surface of the tree without being embedded in the wood. Therefore, the reinforcement hardware described in Patent Document 3 and Patent Document 4 has no problem that wood must be processed in advance in a factory. However, the reinforcing metal fittings of Patent Document 3 and Patent Document 4 have only one additional reinforcing plate, and there is no additional reinforcing plate in one axial direction among the three axes of XYZ, and there is a problem that the axial direction is weak. It was. In addition, since the additional reinforcement board of patent document 4 is a different body from the L-shaped reinforcement metal fitting, its intensity | strength is weaker than patent document 3. FIG. Moreover, since the reinforcement metal object of patent document 3 and patent document 4 is exposed, there existed a problem that the designability was bad.

Japanese Patent Laid-Open No. 10-25811 JP 2005-200907 A JP 2001-65066 A JP 2006-161322 A

  The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a reinforcing member for a wood joint that can be attached at a construction site without requiring complicated wood processing in advance in a factory. And It is another object of the present invention to provide a reinforcing member for a wood joint that can effectively use a wall surface and can realize a joint such as a rigid joint. Moreover, it aims at providing the reinforcing member excellent in the designability.

In order to achieve the above object, the reinforcing member of the wood joint portion of the present invention is an L-shaped vertical plate having a surface abutting on the outer surface of the column and a horizontal plate having a surface abutting on the outer surface of the horizontal member. In the reinforcing member of the wood joint portion having the first hardware formed on the second material and the second hardware having a surface in contact with the outer surface of the horizontal member, the first hardware is formed from the back surface of the vertical plate. Rutotomoni comprises a horizontal reinforcement rib which extends parallel to the horizontal plate, the vertical reinforcing ribs extending perpendicular rear surface and from the back surface of the horizontal plate to the vertical plate and the horizontal plate of the vertical plate, the horizontal reinforcing ribs And the vertical reinforcing rib are connected, the vertical plate of the first hardware is fixed to a column, and the first hardware and the second hardware are fixed by a through bolt across a horizontal member. Features.

Both the first hardware and the second hardware are in contact with only the outer surface of the pillar and the horizontal member. Therefore, the present invention can solve the problem that, as in Patent Documents 1 and 2, since the reinforcing member is embedded in the wood, complicated processing of the wood must be performed in the factory in advance. In addition, even existing wooden buildings can be easily reinforced. The present invention also includes a horizontal reinforcing rib extending parallel to the horizontal plate from the back surface of the vertical plate, and a vertical reinforcing rib extending perpendicularly from the back surface of the vertical plate and the back surface of the horizontal plate to the vertical plate and the horizontal plate. Therefore, additional reinforcement is provided in two of the three XYZ axes. In addition, since the horizontal member is sandwiched between the first hardware and the second hardware by the through bolts, the fixing force between the horizontal material and the first hardware is increased, resulting in a firm joint such as a rigid joint. . Further, since the horizontal member is sandwiched between the first hardware and the second hardware by the through bolts, the horizontal material is prevented from being split. Further, since the horizontal reinforcing ribs and the vertical reinforcing ribs are connected and integrated, the strength of the hardware is increased and a firmer joining is achieved.

  In the reinforcing member for a wood joint portion according to the present invention, the second hardware is provided with a surface that comes into contact with the outer surface of the column, and is fixed to the column.

  Since both the first hardware and the second hardware connected by through bolts with the horizontal member interposed therebetween are fixed to the column, the separation moment of the horizontal member becomes larger. For example, if the second hardware is not fixed to the column, the beam or girder is vulnerable to a downward moment about the first hardware.

  In the reinforcing member for a wood joint portion of the present invention, a covering material covering the first hardware is provided, and the covering material is fixed to the column, the horizontal member, and the first hardware.

  Since the 1st metal object is covered with the coating | covering material and is not exposed, the designability improves. Also, the first hardware is less likely to rust. Since the covering material is fixed to the column, the horizontal member, and the first hardware, the covering material, the horizontal material, and the first hardware become a composite beam, and the section modulus is increased to increase the bending moment resistance performance. As described above, it is not an effect of only the covering, but an integral reinforcing member.

  In the reinforcing member for a wood joint portion according to the present invention, the covering material is made of wood.

  Since the exposed portion of the reinforcing member is the same wood as the pillar, the reinforcing member is less noticeable and the design is further improved.

  In the reinforcing member of the wood joint portion of the present invention, one or more first hardware and a covering material are added to the lower stage of the first hardware, and the lower first hardware is fixed to the upper covering material. To do.

  The triangular shape of the reinforcing structure is increased by providing the first hardware with a multistage structure below the pillar. Therefore, the section modulus between the column and the horizontal member is increased, the bending stress is increased, and a stronger bond is obtained.

In the wood joining structure of the present invention, a plurality of third hardware and a plurality of fourth hardware are further used together with a plurality of the first hardware and the plurality of second hardware, and the penetrating material is passed through the first horizontal member. The first hardware and the second hardware fixed with bolts are respectively fixed to the third hardware and the fourth hardware with through bolts across the pillar, and the extending direction of the first horizontal member is Also in the second horizontal member extending in the right-angle direction, the first hardware and the second hardware fixed by the through bolt are connected to the third hardware and the fourth hardware by the through bolt across the pillar. It is characterized by being fixed to each .

  Since the horizontal members (for example, beams and beams) located between the same columns are firmly joined by the reinforcing member of the present invention, the horizontal members are integrated with each other through the columns. Similarly, the second horizontal member (for example, the girder and the girder) extending in the direction perpendicular to the extending direction of the horizontal member is similarly integrated, and is firmly joined in two orthogonal directions. .

  In the wood joining structure of the present invention, the third hardware is the same shape as the first hardware, or the fourth hardware is the same shape as the second hardware, or the second hardware is the first hardware. It has the same shape.

  If there is no problem such as space and the third hardware can be made the same shape as the first hardware, or if the fourth hardware can be made the same shape as the second hardware, or the second hardware is the same as the first hardware. If the same shape can be achieved, the parts can be shared.

It is not displayed in proportion to the dimensions.

[First Embodiment]
A reinforcing member 100 for a wood joint portion according to a first embodiment of the present invention will be described with reference to FIGS. The reinforcing member 100 of the wood joint portion of the first embodiment includes a metal first hardware 1, a metal second hardware 2, a wood upper covering material 3, a wood lower covering material 4 and a bolt B for fixing them. And a fixing part such as a coach screw C.

  As shown in FIGS. 1, 3, and 6, the first hardware 1 is formed in an L-shape in which a vertical plate 11 that contacts the outer surface 91 a of the through pillar 91 and a horizontal plate 12 that contacts the outer surface of the beam 92 are formed. Has been. And the horizontal reinforcement rib 13 is parallel to the horizontal plate 12 from the back surface 11b of the vertical plate 11 on the opposite side to the surface 11a of the vertical plate 11 in contact with the through pillar 91 so that the L-shape becomes an F-shape. It is extended and provided. Furthermore, the back surface 12b of the horizontal plate 12 on the opposite side to the surface 12a of the horizontal plate 12 that contacts the lower outer surface 92a of the beam 92 and the vertical plate 11 so as to divide the F-shaped inner side into two. From the back surface 11b, vertical reinforcing ribs 14 are provided so as to extend to both the vertical plate 11 and the horizontal plate 12. The horizontal reinforcing ribs 13 and the vertical reinforcing ribs 14 are integrated so as to intersect in a cross shape and are provided so that the back surface of the vertical plate 11 is divided into four. As described above, the first hardware 1 is reinforced in all directions of the XYZ axes by the horizontal reinforcing rib 13 and the vertical reinforcing rib 14. The horizontal reinforcing ribs 13 and the vertical reinforcing ribs 14 are formed so as to be integrated with the vertical plate 11 and the horizontal plate 12, and there are methods such as welding and casting. In addition, when the vertical plate 11 and the horizontal plate 12 are formed by bending a sheet metal, a reinforcing bead can be formed at the bent portion for additional reinforcement.

  As shown in FIGS. 1, 4, and 6, the second hardware 2 has an L-shaped horizontal plate 21 that contacts the outer surface 92 b on the upper side of the beam 92 and a vertical plate 22 that contacts the outer surface 91 a of the through pillar 91. Is formed. The outer shape of the vertical plate 22 is formed in a substantially semi-elliptical shape with the top as a vertex. A reinforcing plate 23 is formed in an arc shape extending from the vertical plate 22 in the direction opposite to the through pillar 91. The arc-shaped reinforcing plate 23 partially covers the inner surface of the L-shaped vertical plate 22 in an arc shape.

  Next, the joining structure of the 1st metal fitting 1 and the 2nd metal fitting 2 is demonstrated using FIGS. The beam 92 is joined to the through pillar 91 by press-fitting a tenon (not shown) of the beam 92 into the tenon hole (not shown) of the through pillar 91. The reinforcing member 100 of the present embodiment reinforces the joining. One first hole 12 c is formed in the center of the tip of the first hardware 1. Here, those that have penetrated are referred to as “holes”, and those that have not penetrated are referred to as “holes”. A first hole 21a is penetrated through the horizontal plate 21 of the second hardware 2 corresponding to the first hole 12c. A through hole (not shown) is also formed in the beam 92 corresponding to the first hole 12 c of the first hardware 1. Bolts B fitted with washers are passed through these three holes and screwed with washers and nuts. Thereby, the first hardware 1 and the second hardware 2 are fixed with the beam 92 interposed therebetween. Thus, the bolt B is first penetrated so that the position of the hole of the bolt B does not shift. If the nut is screwed in, the nut may be tightened later.

  The first hardware 1 is screwed to the through-pillar 91 by bolts B that are passed through holes 11 c that are penetrated at four positions on the vertical plate 11 of the first hardware 1. Then, the first hardware 1 is screwed to the beam 92 by the coach screw C which is passed through the second holes 12d on the left and right sides which are penetrated through the horizontal plate 12 of the first hardware 1. At this time, the positions of the holes penetrated in the four vertical, left and right portions of the vertical plate 11 of the first hardware 1 are hit by the penetrated bolt B on the beam 92 side and the beam beam 93 side to which the first hardware 1 is fixed. It is shifted up and down so as to cross in a cross (see FIG. 6).

  The second hardware 2 is screwed to the beam 92 by the coach screw C passed through the second holes 21b that are penetrated in the left and right two positions of the horizontal plate 21 of the second hardware 2 near the vertical plate 22.

  As shown in FIG. 5, another beam 92 and two beam beams 93 are inserted into the remaining column 91 in the remaining three directions by tenons and tenon holes. Similarly, the first hardware 1 and the second hardware 2 are screwed to the one beam 92 and the two beam beams 93 by bolts B and a coach screw C.

  Two holes 22a are formed in the vertical plate 22 of the second hardware 2 in the vertical direction of the reinforcing plate 23, and two through holes (not shown) are also formed in the through pillar 91 corresponding to the holes 22a. Has been. As shown in FIG. 6, on the upper side 92b of the beam 92, the width is the width of the horizontal plate 21 of the second hardware 2, and the height is the diameter of the hole 22a penetrated through the vertical plate 22 of the second hardware 2. A hardwood spacer 94 having a length corresponding to the length of the horizontal plate 21 of the second hardware 2 is screwed with a plurality of coach screws C. The screw C to be screwed is submerged in the hardwood spacer 94. On the hardwood spacer 94 screwed to the upper side 92b of the beam 92, the second hardware 2 is passed through the second hole 21b drilled in the left and right two positions near the vertical plate 22 of the horizontal plate 21. To the hardwood spacer 94 and the beam 92. The second hardware 2 is screwed to the other beam 92 in the same manner. The bolt B is penetrated through the first hole 21a penetrated through the horizontal plate 21 of the second hardware 2 and the first hole 12c penetrated through the center of the tip of the first hardware 1 so that the first hardware 1 and the second hardware 2 are firmly fixed. It is fixed with the wood spacer 94 and the beam 92 interposed therebetween. Further, the bolt B is passed through the two holes 22 a that are penetrated through the vertical plate 22 of the second hardware 2, and the opposing second hardware 2 is screwed by the two bolts B with the through pillar 91 interposed therebetween. At this time, the girder beam 93 and the other girder beam 93 screw the second hardware 2 on the upper side of the girder beam. Similar to the beam 92, the opposing second hardware 2 is screwed by the bolt B with the through pillar 91 interposed therebetween. The second hardware 2 fixed to the beam 92 is higher than the second hardware 2 fixed to the beam beam 93 by the thickness of the hardwood spacer 94. For this reason, the bolt B passed through the two holes of the vertical plate 22 of the second hardware 2 can be crossed in a cross without hitting. In this way, the second hardware 2 can be commonly used by using the hardwood spacer 94.

  As described above, in the reinforcing member 100 of the wood joint portion of the present invention, the first hardware 1 and the second hardware 2 are in contact with only the outer surfaces of the through pillars 91, the beams 92, and the beam beams 93. Therefore, the present invention can solve the problem that, as in Patent Documents 1 and 2, since the reinforcing member is embedded in the wood, complicated processing of the wood must be performed in the factory in advance. In addition, even existing wooden buildings can be easily reinforced.

  The present invention also includes a horizontal reinforcing rib 13 extending in parallel with the horizontal plate 12 from the back surface 11b of the vertical plate 11 of the first hardware 1, and the vertical plate 11 and the back surface 11b of the vertical plate 11 and the back surface 12b of the horizontal plate 12. Since the vertical reinforcing rib 14 extending perpendicularly to the horizontal plate 12 is provided, it is an additional reinforcement in two of the three XYZ axes. In addition, since at least one of the beam 92 or the girder beam 93 is sandwiched between the first hardware 1 and the second hardware 2 by the through bolt B, the first hardware 1 to at least one of the beam 92 or the girder 93 is used. This increases the adhesion force and provides a strong bond.

  Further, since at least one of the beam 92 or the beam beam 93 is sandwiched between the first hardware 1 and the second hardware 2 by the through bolt B, at least one of the beam 92 or the beam beam 93 is prevented from being split.

  In addition, since both the first hardware 1 and the second hardware 2 connected by the through bolt B with the at least one of the beam 92 or the beam beam 93 sandwiched are fixed to the through pillar 91, at least the beam 92 or the beam beam 93 One separation moment becomes larger.

  Further, since the horizontal reinforcing ribs 13 and the vertical reinforcing ribs 14 are connected and integrated, the strength of the hardware is increased, resulting in stronger bonding.

  In FIG. 5, two beams 92 and girders 93 are joined to the same column 91. The joint structure is such that two beams 92 and two beam beams 93 are sandwiched between the first hardware 1 and the second hardware 2 by through bolts B, and two pairs of the second pairs facing each other. Two pairs of second hardware 2 facing each other and one hardware 1 are fixed with a through bolt B across the same through column 91. Thus, since the beam 92 and the beam beam 93 orthogonal to each other are firmly joined to the same column 91 by the reinforcing member of the present invention, the transverse members orthogonal to each other have an integrated structure via the column 91, It becomes a strong joint integrated in two orthogonal directions. Of the two pairs of first hardware 1 facing each other, one first hardware 1 corresponds to the third hardware, and of the two pairs of second hardware 2 facing each other, the second hardware 2 is the second hardware. Corresponds to 4 hardware.

  Moreover, in the case of the pillar 91 located in the edge of a building, there is no 1st hardware 1 and 2nd hardware 2 which become a pair which faced each other. At this time, if the third hardware 1 made of sheet metal and the first hardware 1 are paired, and the fourth metal hardware 2 made of sheet metal and the second hardware 2 are paired and fixed with the through bolts B across the same pillar 91, they are orthogonal. It becomes a strong joint integrated in two directions. Here, the 3rd metal fitting and the 4th metal fitting can also be made into an integral sheet metal.

  The reinforcing member 100 of the wood joint portion according to the first embodiment of the present invention also includes an upper covering material 3 and a lower covering material 4. The upper covering material 3 is a member that covers the upper side of the horizontal reinforcing rib 13 of the first hardware 1. As shown in FIG. 7, the upper covering material 3 has a shape in which a rectangular lower end is cut out. A rectangular first countersink 3a, which is the relief of the horizontal plate 12, is formed on the upper surface, and a second countersink 3b, which is the relief of the vertical plate 11, is provided on the front surface in the direction of the column 91, which is a relief of the vertical reinforcing ribs 14. A first groove 3c having a shape is formed on the front surface, and a square second groove 3d that is a relief of the bolt B that is passed through the first hole 12c of the horizontal plate 12 communicates with the first groove 3c on the upper surface. Two square third grooves 3e which are relief of the coach screw C passed through the second hole 12d are on the upper surface, and two holes 3f which are relief of the bolt B which is passed through the hole 11c of the vertical plate 11 are on the front face. It is formed.

  The upper covering material 3 is inserted into the first hardware 1 fixed to the through pillar 91 and the beam 92 or the girder beam 93, and the first upper and lower first holes 3 g penetrating through the side surface of the upper covering material 3 and the first The upper covering material 3 is screwed to the first hardware 1 with two bolts B penetrating the upper and lower first holes 14 a that are penetrated through the vertical reinforcing ribs 14 of the hardware 1. Then, the upper covering material 3 is screwed to the first hardware 1 even with the coach screw C passing through the two left and right holes 13 a pierced in the horizontal reinforcing rib 13 of the first hardware 1.

  The lower covering material 4 is a member that covers the lower side from the horizontal reinforcing rib 13 of the first hardware 1. As shown in FIG. 8, the lower covering material 4 has a shape in which a rectangular lower end shorter than the upper covering material 3 is cut out in two steps. The square first countersink 4a that is the relief of the horizontal reinforcing rib 13 is on the top surface, and the second countersink 4b that is the relief of the vertical plate 11 is on the front surface that is in the direction of the column 91. Bolts that are passed through the holes 11c of the vertical plate 11 are formed with two square second grooves 4d that are escapes of the coach screw C that are passed through the holes 13a of the horizontal reinforcing rib 13 on the front surface and the upper surface of the first groove 4c. Two holes 4e which are escapes of B are formed in the front surface.

  The lower covering material 4 is inserted into the first hardware 1 fixed to the through pillar 91 and the beam 92 or the girder beam 93, and the first hole 4 f and the first hardware 1 penetrated through the side surface of the lower covering material 4. The lower covering material 4 is screwed to the first hardware 1 with a bolt B that passes through the second hole 14 b that is penetrated through the vertical reinforcing rib 14. Then, the lower covering material 4 is screwed to the through-pillar 91 with the coach screw C passing through the second hole 4 g that is passed through the lower covering material 4 toward the post 91. Bolts B, nuts, washers, and coach screws C for fixing the upper covering material 3 and the lower covering material 4 are colored to improve the design, or are subjected to a wood digging and filling process. When the first hardware 1 has a weld bead or a reinforcement bead, the clearance of the clearance is also necessary for the upper coating material 3 and the lower coating material 4. In the above-described embodiment, the first cover 3 and the lower cover 4 are formed with the first countersinks 3a and 4a and the second countersinks 3b and 4b, but the first hardware 1 is concealed on the ceiling or the like. In this case, a part of the countersink may be omitted, and a spacer that eliminates the step may be added.

  Since the first hardware 1 is covered with the first coating material 3 and the second coating material 4 and is not exposed, the design property is improved. Also, the first hardware 1 is less likely to rust. And since the 1st coating | covering material 3 and the 2nd coating | covering material 4 are fixed to the beam 92 or the girder beam 93 and the through pillar 91, and the 1st metal fitting 1, a coating | covering material, a horizontal member, and a 1st metal fitting become a composite beam, The section modulus increases and the bending moment resistance performance increases. The same applies to the pillars. As described above, the effect is not only the covering, but an integrated reinforcing member. Since the 1st coating | covering material 3 and the 2nd coating | covering material 4 are timber, the exposed part of the reinforcement member 100 becomes the same timber as a pillar, the reinforcement member 100 becomes difficult to stand out, and the design property improves more. Although the shape of the 1st coating | covering material 3 and the 2nd coating | covering material 4 is a rectangle, the notch shape below a front-end | tip does not limit the number of steps. In the above-described embodiment, the first covering material 3 and the second covering material 4 are wood. However, the present invention is not limited to wood. For example, the composite material injection-molded with an FRP material is designed. However, it is only necessary to have the same strength as wood even if it is sprayed with high paint.

  In the above-described embodiment, the first hardware 1 and the second hardware 2 are fixed to the beam 92 and the other beam 92 or the beam beam 93 and the other beam beam 93 with the bolt B so as to sandwich the through column 91. However, when the beam 92 or the beam beam 93 is only one, a vertical plate (not shown) is provided on the side where the beam 92 is not provided, and the first metal 1 and the second metal 2 are passed through the pillar 91 with a bolt B penetrating therethrough. Secure to.

  In the above-described embodiment, the first hardware 1 fixed to the beam 92 and the first hardware 1 fixed to the beam beam 93 have the same height. However, the height may not be the same. If the beam 92 and the beam beam 93 are different in height, the beam 92 and the beam beam 93 are different in height from the lower side 92a because the upper side 92b is aligned. In this case, an auxiliary beam (hardwood) whose width is the beam width, height is the difference in beam height, and length is the same as the length of the first covering material, is placed on the lower side of the lower one. A plurality of coach screws C are screwed onto 92a, and the first hardware 1 is fixed after the heights are aligned. At this time, the coach screw C to which the auxiliary beam is screwed is submerged in the auxiliary beam.

  In the above-described embodiment, the second hardware 2 can be fixed to the through-pillar 91, but there are cases where this is not possible. FIG. 9 is a diagram of a first modification showing this. In the first modification, the through pillar 91 does not extend above the beam 92 or the beam beam 93, and is a bundle 95 separate from the through pillar 91. Therefore, the first hardware 1 is connected to the second hardware 2B without the vertical plate 22 by the through bolt B with the beam 92 interposed therebetween. As described above, the first hardware 1 is connected to the second hardware 2B that is not fixed to the through column 91, but the second hardware 2B is a long plate that connects the beam 92 and the other beam 92. By connecting with the through bolt B, the detachment moment of the beam 92 is increased. Further, in the case of the pillars 91 and the beams 92 located at the ends, the second hardware 2B may be bent into a rectangle (L shape) and fixed to the beam beam 93 with a plurality of bolts B and a coach screw C.

  In the above-described embodiment, since the height of the second hardware 2 is lower than that of the first hardware 1, it can be used even when there is no space above the beam 92 or the beam beam 93. However, if the strength is required and there is a space above the beam 92 or the beam beam 93, the same hardware as the first hardware 1 can be used in common as the second hardware 2. FIG. 10 is a diagram of a second modification showing this.

  In the above-described embodiment, the first hardware 1 is used at the joint portion between the through pillar 91 and the beam 92 (or the beam beam 93). However, the first hardware 1 is also used at the place where the through pillar 91 and the foundation / foundation are joined. The same hardware as the hardware 1 can be used in common. The fixing method is the same as that of the first embodiment, and the first hardware 1 is screwed to the through-pillar 91 by the bolts B that are passed through the holes 11c that are drilled in the upper, lower, left and right four positions of the vertical plate 11 of the first hardware 1. The first hardware 1 is screwed to the base / foundation by the coach screw C passed through the second holes 12d on the left and right sides of the horizontal plate 12 of the first hardware 1. The bolt that penetrates the first hole 12c that is penetrated in the center of the tip of the first hardware 1 serves as an anchor bolt from the base portion.

[Second Embodiment]
Next, the reinforcing member 100B of the wood joint portion of the second embodiment will be described with reference to FIG. FIG. 11 substantially corresponds to FIG. 6 in the reinforcing member 100 of the first embodiment. In the reinforcing member 100B of the second embodiment, the same reference numerals are given to portions having the same configuration as the reinforcing member 100 of the first embodiment, and detailed description thereof is omitted.

  In the reinforcing member 100B of the wood joint portion of the second embodiment, the first hardware 1 is provided in two upper and lower stages. The upper covering material 3 and the lower covering material 4 that cover the upper first hardware 1 are the same as those of the reinforcing member 100 of the first embodiment. The lower covering material 4 </ b> B covering the upper first hardware 1 extends longer than the lower upper covering material 3. The upper covering material 3B covering the upper first metal piece 1 extends longer than the upper lower covering material 4B. In this way, the covering material becomes gradually longer as it goes upward, and has an inverted triangular shape.

  An end portion of the upper covering material 3B in the upper stage is screwed with a bolt B penetrating the upper covering material 3B and the beam 92. The lower lower covering material 4B is screwed with a bolt B penetrating the lower covering material 4B, the upper covering material 3B, and the beam 92. The lower upper covering material 3 is screwed to the upper lower covering material 4B with a coach screw C penetrating the upper covering material 3. The method for fixing each covering material to the first hardware 1 is the same as in the first embodiment.

  Thus, by forming a multistage structure, the triangular shape of the reinforcing structure becomes large. For this reason, the section modulus between the through pillar and the horizontal member is increased, the bending stress is increased, and a stronger bond is obtained.

[Third Embodiment]
Next, the reinforcing member of the wood joint part of 3rd Embodiment is demonstrated using FIG. 12, FIG. In the reinforcing member of the third embodiment, the same reference numerals are given to portions having the same configuration as the reinforcing member of the first embodiment, and detailed description thereof is omitted.

  A horizontal brace may be incorporated into the four columns for earthquake resistance. The reinforcing member of the third embodiment corresponds to the horizontal brace. The horizontal brace joining plate 5 is a member made of a metal material that joins the through column 91 and the joining plate (not shown) on the horizontal brace side. As shown in FIG. 13, the flange 52 is formed by bending both ends of the plate material to a brace attachment angle by sheet metal processing. Each flange 52 has a hole for joining with a joining plate on the horizontal brace side with a bolt and a nut. The central attachment portion 51 has two left and right long holes 51 a for fixing the attachment portion 51 to the through pillar 91.

  As shown in the enlarged view of FIG. 12, a notch 14 c through which the horizontal brace joining plate 5 can penetrate is provided above the vertical reinforcing rib 14 of the first hardware 1. The horizontal brace joining plate 5 passes through the notch 14c and is screwed by a bolt B passing through the long hole 51a of the horizontal brace joining plate 5 and the hole 11c of the first hardware 1. At this time, the horizontal brace joining plate 5 is penetrated through the notch 14c in the same manner with the through pillar 91 interposed therebetween, and the horizontal brace joining plate 5 and the first hardware 1 are screwed together with the through pillar 91 through the bolt B. Is done. The horizontal brace joining plate 5 is also screwed in the beam 92 direction and the beam beam 93 direction with the column 91 interposed therebetween. Thus, the reinforcing member of the present invention can cope with a horizontal brace by cutting out the vertical reinforcing rib 14. At this time, the upper covering material 3 inserted into the first hardware 1 is provided with a notch to correspond to the horizontal brace.

  In the above-described embodiment, the joining of the reinforcing structure has been described using the beam 92 and the girder beam 93 as the horizontal member. However, as another horizontal member forming the joint, it is bridged horizontally with the framework of the building. Also included are structural materials, also referred to as body differences, girders, etc. In the above-described embodiment, the joining of the reinforcing structure has been described using the through pillars 91 as the pillars. However, as other pillars that form the joint portions with the horizontal members, structural materials such as main pipe pillars are also included.
