Description

  The present invention relates to a construction hardware that reinforces the joining of structural members by attaching them to the corners where the structural members intersect at right angles, such as foundations and columns, columns and beams of wooden houses.

  In a wooden house, for example, a corner hardware 1 in which a metal plate as shown in FIG. 1 is bent into an L-shape is known as a construction hardware for joining two structural members that are orthogonal to each other such as a base and a pillar, and a pillar and a beam. (See Patent Document 1). Reference numeral 2 is a pillar, and reference numeral 3 is a base. The corner hardware 1 is integrally provided with a first mounting surface portion 4 fixed to the pillar 2 and a second mounting surface portion 5 fixed to the upper surface of the base, and a plurality of fixtures are inserted into the first mounting surface portion 4 and the second mounting surface portion 5. A hole 6 is formed. Reference numeral 7 is a fixing tool such as a screw.

  In the case of such a reinforcing structure, as shown in FIG. 2, when the pillar 2 is displaced so as to be pulled upward due to a strong earthquake or the like, the corner hardware 1 is extended, and as a result, the pillar 2 is detached from the base 3. The house collapses. This tendency is strong even when a triangular rib is basically arranged between the first mounting surface portion 4 and the second mounting surface portion 5 in the corner hardware having an L shape.

  In this regard, the hole-down hardware 8 illustrated in FIG. 3 has a structure in which an engagement hardware 9 fixed to the column side and an anchor bolt 11 fixed to the foundation concrete 10 are strongly connected by a nut 12 to counter a considerable pulling force. can do. This is because the engagement hardware 9 and the anchor bolt 11 may be made of a material that is sturdy, but the lower edge 13 of the engagement hardware 9 is the column of the column to which the engagement hardware 9 is attached. It depends on the contact with the side. That is, as shown in FIG. 4, when an upward pulling force acts on the pillar 2, the engagement hardware 9 tends to rotate around the engagement point with the anchor bolt 11 toward the pillar 2 side. The lower edge 13 of the object 9 collides with the column side surface to prevent this turning tendency. If the material of the pillar 2 is very soft, the lower edge 13 of the engagement hardware 9 is inserted into the pillar 2 and the pillar 2 is easily pulled out.

  On the other hand, if the L-shaped corner hardware 1 is formed into a box shape as shown in FIG. 5 (a) (referred to as a corner hardware 14), and the corner hardware 14 itself has a sturdy and hard-to-deform structure, the column in a normal state. Although the connection state between the base 2 and the base 3 is strengthened, the phenomenon shown in FIGS. That is, when the column 2 and the base 3 are reinforced and joined by the corner hardware 14 as shown in FIG. 5 (b) and the column 2 is pulled upward as shown in FIG. The pillar 2 is lifted from the base 3 due to deformation of the fixture 7 (screw) to which the first attachment surface portion 4 is attached. At this time, since the force with which the second mounting surface portion 5 of the corner hardware 14 is fixed to the base 3 by the fixture 7 is strong, the corner hardware 14 remains in the position with the second mounting surface portion 5 in contact with the upper surface of the base 3. Remain. For this reason, the corner | angular part P of the 1st attachment surface part 4 and the 2nd attachment surface part 5 of the corner metal fitting 14 will remove | deviate from the side surface of the pillar 2, and will be in the state which lost the resistance part at the time of the corner metal fitting 14 rotating. When the upward movement of the pillar 2 becomes large, as shown in FIG. 7, since the corner hardware 14 is rigid, the corner portion P starts to rotate around the tip of the second mounting surface portion 5 as a whole, and the corner portion P Moves in a gap between the pillar 2 and the base 3 caused by pulling out, and the corner metal piece 14 can no longer stop rotating. Eventually, the pillar 2 is pulled out from the base 3.

Further, for example, when using the corner hardware 1 as described above on the two side surfaces of the column 2 at the junction between the column 2 and the base 3, a fixture such as a screw driven into the column 2 from the first mounting surface 4 7 may collide inside the pillar. This will always occur when the same corner hardware 1 is used on the two side surfaces and the fixture 7 is placed in the same vertical position and the fixture is driven perpendicularly. In addition, even when the fixture 7 is driven in from opposite side surfaces, it is necessary to shift the position of the fixture 7 in the horizontal direction. Although the problem can be solved by shortening the fixing tool 7, the strength is insufficient.
For this reason, at least two types of construction hardware having different heights of the fixture insertion holes must be prepared, and the cost is high, and the trouble of using the two types of construction hardware is complicated.

JP 2001-107457 A

  The problem to be solved by the present invention is that, when reinforcing joints between structural members in a wooden house using a reinforcing metal fitting for construction, even if the construction hardware is a rigid structure, the strength against pulling out the pillar is high. Also, even if the same building hardware is used for two surfaces of one structural material (two orthogonal surfaces or two parallel surfaces), the fixtures used for fixing are prevented from colliding inside the column. The challenge is to provide construction hardware that can be used.

The construction hardware of the present invention includes a main body and a dedicated spacer separately from the main body.
The main body integrally includes a first attachment surface portion and a second attachment surface portion that extend in directions orthogonal to each other.
A plurality of fixture insertion holes are formed in each of the first mounting surface portion and the second mounting surface portion.
The dedicated spacer is used by being polymerized on the back surface of the second mounting surface portion. The dedicated spacer has a thickness, and the thickness P increases the corner P of the second mounting surface portion and the first mounting surface portion. It shall be. The dimension of the thickness is set according to how far it can resist the pulling that acts on the column due to an earthquake or the like.

On the other hand, the thickness of the dedicated spacer is not less than the diameter of the fixture insertion hole formed in the first attachment surface portion and not more than the distance in the direction perpendicular to the second attachment surface portion between these fixture insertion holes.
In order to stabilize the function of the dedicated spacer, it is desirable that the length of the spacer in the direction orthogonal to the first mounting surface portion is equal to or larger than the length of the second mounting surface portion.

The dedicated spacer material may be a synthetic resin in addition to a metal. However, in the case of synthetic resin, it is harder than wood. The dedicated spacer may have a through hole at a position corresponding to the fixture insertion hole of the second mounting surface portion, or may be a simple plate as long as it can be screwed directly into the material. good.
The dedicated spacer is preferably a washer type provided with a fixture insertion hole.

In a wooden house, two structural members are orthogonally crossed, the main body of the construction hardware is placed at the corner of the joint, the first mounting surface is brought into contact with the side of one structural member, and the second mounting surface is connected to the other structure. The two structural materials are joined by abutting against the side surface of the material and driving the fixture into the structural material through the fixture insertion holes of the first mounting surface portion and the second mounting surface portion.
When building hardware is attached to two corners of one structural material, a dedicated spacer is used for one main body, and the dedicated spacer is polymerized on the back surface of the second mounting surface portion. Then, the fixture insertion hole formed in the first attachment surface portion of the main body and the fixture insertion hole formed in the first attachment surface portion of the other hardware main body are only the thickness of the dedicated spacer in the direction orthogonal to the base end. Since the positions are shifted, the construction hardware can be fixed without causing the fixtures that have entered the one structural material from different side surfaces to collide with each other inside the structural material.

When the corner P of the first mounting surface part and the second mounting surface part of the building hardware is raised by the dedicated spacer, when the pulling force is applied to the column, until the lower edge of the column reaches its position, Rotation can be prevented, and the resistance to the action of the column being pulled out from the base during an earthquake is increased. In addition, although the column and the base are taken as an example, the same applies to the junction between the column and the beam. This is particularly effective when the construction hardware itself used for reinforcement is hard to be deformed.
Moreover, according to this invention, even if it is a case where construction hardware is each attached to two different side surfaces of a structural material, the same construction hardware can be used by using a dedicated spacer. For this reason, it is not necessary to prepare two types of construction hardware with different positions of the fixture insertion holes.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 8 shows a first embodiment, and the construction hardware 1 (corner hardware) is composed of a main body 15 and a dedicated spacer 16 separate from the main body 15.
The main body 15 is formed by press-molding a single strong metal strip and integrally integrating the first mounting surface portion 4 and the second mounting surface portion 5 extending in directions orthogonal to each other and the side walls 17 and 17 connecting these on both sides. It is provided. The second mounting surface portion 5 is formed by bending the side walls 17 on both sides and has a double structure. This structure is a so-called box shape, and is a rigid construction hardware 1 that is not easily deformed by an external force. A predetermined number of fixture insertion holes 6 are formed in the first mounting surface portion 4 and the second mounting surface portion 5.

In this embodiment, the dedicated spacer 16 is made of a flat rectangular metal plate, has substantially the same width as the second mounting surface portion 5, and has a length in the direction orthogonal to the first mounting surface portion 4. It is formed slightly longer.
The dedicated spacer 16 is provided with a through-hole 18 having the same shape as that of the second attachment surface 5 at a position corresponding to the fixture insertion hole 6.
The dedicated spacer 16 has a thickness. This is because the corner portion P of the first mounting surface portion 4 and the second mounting surface portion 5 is raised depending on the thickness. Specifically, for the purpose of preventing the fixture 7 for attachment from colliding in the pillar (described later), the thickness is equal to or greater than the diameter of the fixture insertion hole 6 formed in the first attachment surface portion 4. And it is set as the dimension below the distance in the direction orthogonal to the 2nd attachment surface part 5 between the fixture insertion holes 6. FIG.

FIG. 9 is an example in which this building hardware 1 is used at a joint between the pillar 2 and the base 3, and the dedicated spacer 16 is used between the second mounting surface portion 5 of the main body 15 and the upper surface of the base 3. It is being fixed to the pillar 2 and the base 3 with the fixing tool 7 (screw).
With this structure, even if the pulling force acts on the pillar 2 and the pillar 2 is lifted up somewhat (see FIG. 6), the corner P of the construction hardware 1 remains until the lower edge of the pillar 2 reaches this position. It will not come off from the side. Therefore, during this time, the main body 15 of the construction hardware 1 does not start to rotate, and can strongly resist the pulling force against the pillar 2. In addition, the dedicated spacer 16 can prevent the tip of the second mounting surface portion 5 from sinking into the base 3.
By adopting the reinforcement structure of the joint portion using the building hardware 1, a highly earthquake-resistant house can be constructed.

FIG. 10 shows a second embodiment in which the construction hardware 1 has a different structure. A main body 15 and a dedicated spacer 16 are provided. The main body 15 is formed by bending a single metal plate body into an L shape to form a first mounting surface portion 4 and a second mounting surface portion 5, and the surface side (inner corner side) so as to be continuous across these connecting portions. Reinforcing reinforcing ribs 19 are formed.
In the example shown in the figure, the connecting portion between the first mounting surface portion 4 and the second mounting surface portion 5 is curved, but the corner portion P may be bent at a right angle.

The first attachment surface portion 4 is formed with fixing tool insertion holes 6 on both sides of the tip portion and on both sides of the reinforcing rib 19 at the intermediate portion. The second attachment surface 5 is also provided with fixing tool insertion holes 6 on both sides of the tip and on both sides of the intermediate reinforcing rib 19.
In this embodiment, the dedicated spacer 16 is made of a flat rectangular metal plate, is approximately the same width and length as the second mounting surface portion 5, and is located at a position corresponding to the fixture insertion hole 6 of the second mounting surface portion 5. The through-hole 18 is provided.
Further, the thickness of the dedicated spacer 16 is equal to or larger than the diameter of the fixture insertion hole 6 formed in the first attachment surface portion 4, and in a direction orthogonal to the second attachment surface portion 5 between these fixture insertion holes 6. The dimension is less than the distance.

FIGS. 11 and 12 show a use example in which the joint portion between the bases 3 and 3 ′ that are abutted so as to be orthogonal to each other and the corner pillar 2 that stands up at the intersecting portion is reinforced with two building hardware 1 and 1. The foundations 3 and 3 ′ are fixed to the foundation concrete 10 by anchor bolts 11.
A construction hardware main body 15 is arranged at the corner of the joint portion between the base 3 and the corner pillar 2, the first attachment surface portion 4 is brought into contact with the side surface of the corner pillar 2, and the second attachment surface portion 5 is placed on the upper surface of the foundation 3. The fixing tool 7 such as a screw is screwed into the corner post 2 through the fixing tool insertion hole 6 formed in the first mounting surface portion 4, and the fixing tool 7 is screwed into the base 3 through the fixing tool insertion hole 6 of the second mounting surface portion 5. Thus, the corner pillar 2 and the base 3 are joined.

A dedicated spacer 16 is placed on the upper surface of the other base 3 ′ so as to be in contact with the side surface of the corner column 2, and the second mounting surface portion 5 of the main body 15 in another building hardware 1 is superposed on the dedicated spacer 16. The through hole 18 of the dedicated spacer 16 and the fixing tool insertion hole 6 of the second mounting surface portion 5 are matched, and the fixing tool 7 is screwed into the base 3 ′ through the fixing tool insertion hole 6 and the through hole 18. The first attachment surface portion 4 is directly applied to the other side surface of the corner post 2 and attached to the corner post 2 with the fixture 7.
Since the main body 15 in the other construction hardware has a dedicated spacer 16 superposed on the back surface of the second mounting surface portion 5, the height of the first mounting surface portion 4 is the first of the main body 15 installed on the one base 3. 1 The height of the dedicated spacer 16 is higher than that of the mounting surface portion 4. That is, the fixture insertion hole 6 formed in the first mounting surface portion 4 of the main body 15 is disposed at a position higher by the thickness of the dedicated spacer 16 than the fixture insertion hole 6 of the main body 15 installed on the base 3. .

Since the thickness of the dedicated spacer 16 is not less than the diameter of the fixture insertion hole 6 and not more than the distance between the fixture insertion holes 6 positioned above and below, the main body 15 arranged on the base 3 ′ and the main body 15 arranged on the base 3 Then, the fixture insertion hole 6 is positioned completely displaced in the vertical direction.
Therefore, even if the fixture 7 is screwed into the corner post 2 through the fixture insertion hole 6 of one main body 15, it does not collide with the other fixture 7 screwed into the corner post 2 so as to cross this.
If the second mounting surface portion 5 of the main body 15 is placed on the dedicated spacer 16, it is useful because the end of the second mounting surface portion 5 due to deformation of the main body 15 can be prevented as described above.

FIG. 13 uses the building hardware 1 of Example 2 on both sides of the middle pillar 2, where one hardware is only the main body 15 and the other hardware is the building hardware 1 having the dedicated spacer 16.
By using the dedicated spacer 16, it is possible to prevent the fixture 7 such as a screw that is driven from parallel surfaces facing each other from colliding inside the middle pillar 2. In addition, when the fixing tool 7 is driven from the opposed parallel surface, it is possible to prevent the fixing tools 7 from colliding with each other inside the middle column 2 by shifting the position of the hardware in the horizontal direction.
As an example of use, it can also be used to join columns and beams or orthogonal beams.

  14 and 15 show a third embodiment, in which the main body 15 of the construction hardware 1 is box-shaped and also serves as a brace fixing bracket. In this case, the box-shaped column side mounting surface is the first mounting surface portion 4, and the mounting surface to the base is the second mounting surface portion 5. The dedicated spacer 16 is a hard synthetic resin (vinyl chloride or the like), and can be threaded if a tool is used. For this reason, the dedicated spacer 16 in this case is not formed with the through hole 18 corresponding to the fixture insertion hole 6 formed in the second mounting surface portion 5. When the brace 20 is fixed with the structure shown in the figure, it is normal that the positions of the brace fixing brackets on both sides cannot be adjusted in the horizontal direction.

  For this reason, when this construction hardware is fixed together with the middle pillar 2, the base 3 and the brace 20 on both sides thereof as shown in FIG. 15, the dedicated spacer 16 is used for the main body 15 of one construction hardware. Thereby, the screw etc. which were driven in from the both sides inside the middle pillar 2 can be prevented from colliding. Therefore, the same construction hardware can be used on the left and right of the middle pillar 2. Further, since the through hole 18 is not formed in the dedicated spacer 16, the dedicated spacer 16 has an advantage that it can be used in common for the same shape but different positions of the fixture insertion holes 6.

  Although the embodiment has been described above, the present invention is applicable not only to so-called corner hardware mainly composed of vertical pieces and horizontal pieces, but also to general construction hardware having a first mounting surface portion and a second mounting surface portion extending in directions orthogonal to each other. It can be done.
