Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing metal fitting and a wooden building, and is particularly applied as a structural reinforcing means for a wooden building such as a wooden house.

[0002]

2. Description of the Related Art Conventionally, a conventional frame construction method is one of the typical construction methods for wooden houses. This conventional frame construction method is a traditional Japanese construction method and is still known as a commonly used construction method.

In this conventional frame construction method, the foundation, pillars and beams are used as a frame to support the forces acting in the vertical direction of the building, and the earth-painted walls, braces, and bearing walls are arranged so as to surround them. It supports the force acting in the horizontal direction.

[0004]

In the wooden house using the conventional shaft construction method, a reinforcing material is attached to the joint between the base and the pillar to increase the strength of the joint. As the reinforcing material, for example, a reinforcing metal member formed by processing a flat iron material into a flat plate shape or an L shape is used.

FIG. 11 shows an example of the usage state of the reinforcing metal fitting. The reinforcing metal fitting K1 is made of, for example, an iron material having a thickness of 3 [mm] and a width of 3 [cm] processed into a flat plate cross section. , K4 and K5 are fixed to the surface of the joint with K2 and bolts K3.

When the reinforcing metal fitting K1 shown in FIG. 11 is used, a protrusion K6X protruding from the tip surface of one of the two pieces of wood K6 and K7 is formed in the tip surface of the other piece of wood K7. Reinforcing metal fittings K are attached to the outer surface of the abutting portion in a state of abutting by fitting into the hole K7X.
1 is fixed by nails K2 and bolts K3, whereby the tips of the woods K6 and K7 are integrally joined by the reinforcing metal fitting K1.

By the way, since this type of reinforcing metal fitting is mainly intended to support the external force acting on the joint portion with the strength of iron, a relatively thick iron material is used for the reinforcing metal fitting.

However, although a thick iron material is used for the metal fittings for reinforcement, the width of the metal fittings currently used is about 3 cm, which is larger than the width of the pillar (about 10 cm). Since the metal fittings of this kind can be reinforced one-sidedly only as shown in FIG. 11, they are still insufficient from the viewpoint of reinforcing the joints of the frame.

In addition, the number of wooden structures (wooden houses) in recent years is 2
The building is often constructed as a story or a three story, and accordingly, the weight of each joint in the wooden structure is increased. Therefore, in a wooden building, it is considered necessary to strengthen it as a whole by reinforcing it using a reinforcing member suitable for each joint.

The present invention has been made in consideration of the above points, and a reinforcing metal fitting capable of further strengthening the joint strength of a joint portion of wood and a wooden building reinforced by the reinforcing metal fitting. It is a proposal.

Virtual lines IM5, IM6, IM7 and IM8 parallel to the short side S1 or S2 up to 1 or L2 are used as ridge lines so that they can be bent substantially at right angles.

In addition to this, in the reinforcing metal member 18, the main body portion excluding the plate portions P1 to P8 is one of the long sides L1 and L2.
At the position of / 2 and between the long sides L1 and L2,
The bending line IM9 parallel to the short sides S1 and S2 is used as a ridge line so that it can be bent substantially at a right angle.

In the above structure, the first reinforcing metal fitting 1

In this way, the reinforcing metal fitting 18 is fitted to the joint portion between the through column 3A and the body difference 4 (base wheel 6).

At this time, since the reinforcing metal fitting 18 is made of a relatively thin (0.6 [mm]) iron plate, the operator manually attaches the through column 3A and the body gap 4 (base wheel 6) at a predetermined site. It is possible to easily fit the reinforcing metal fitting 18 to the joint portion of (that is, so-called on-site matching).

Further, in the main body portion, each nail hole H4 is located at a position symmetrical with each nail hole H29 to H44 with the imaginary line IM9 as the axis.
5 to H60 are provided respectively.

In this way, each nail hole H1 of the reinforcing metal fitting 18 is
H60 is drilled at a position corresponding to the area of each plate portion P1 to P8 and the main body portion, and this position corresponds to the thickness of the wood at the joint between the through column 3A and the body difference 4 (base wheel 6). The holes are provided so that the nail can be driven even if an error of about several mm occurs.

Therefore, each of the nail holes H1 to H60 can surely hit the nail even if the thickness of the timber at the joint portion has an error of about several mm.

Further, each nail hole H1 to H6 of the reinforcing metal fitting 18
Since 0 is provided in each of the isosceles triangles while maintaining the positional relationship of the vertices, the pressure distribution exerted by the nails on the plate portions P1 to P8 and the main body portion is made uniform.

Therefore, the nail holes H1 to H60 can prevent the nails from being pulled out by an external force acting in a certain specific direction as much as possible, and thus, the nail plates H1 to H60 and the plate portions P1 to P8 and the main body portion can be prevented. It is possible to strengthen the fixing to the joint portion (through column 3A and body difference 4 (base wheel 6)).

As a result, an operator who drives a nail into the reinforcing metal fitting 18 simply drives the nail into each of the nail holes H1 to H60 to pass the reinforcing metal fitting 18 through the pillar 3A and the body gap 4 (base wheel 6). It can be firmly fixed to the joint part with.

Thus, the reinforcing metal fitting 18 can avoid the complexity of nailing work.

According to the above structure, the reinforcing metal fitting 18 is
The joint portion between the through column 3A and the body difference 4 (base wheel 6) that is abutted orthogonally to the through column 3A can be reinforced in multiple directions so as to wrap it in both the vertical direction and the horizontal direction.

Therefore, when an external force acts in the direction of compression with respect to the longitudinal direction of the reinforcing metal fitting 18, the reinforcing metal fitting 18 is
Unlike a conventional rigid body, is capable of absorbing an external force in a form of deformation, and when the external force acts in a direction that extends with respect to the longitudinal direction of the reinforcing metal fitting 18, the thin iron plate has a tenacious tensile force. Appears and can resist external force.

As a result, the reinforcing metal fitting 18 is capable of withstanding a large external force such as an earthquake without holding the connecting portion between the through column 3A and the body difference 4 (base wheel 6) or removing it. Can be realized and thus through pillar 3A
The “structural stickiness” at the joint between the and the body difference 4 (base wheel 6) can be strengthened.

Incidentally, the reinforcing metal fitting 18 has a nail for the through column 3A and nail holes H18 to H28, H34 to H41 and H5 which are formed in the plate portions P5 to P8 and the main body portion.
0 to H60 (Fig. 2) to AR11 direction (Fig. 4 (A))
, AR12 direction (FIG. 4 (A)), AR13 and AR
It is possible to drive from four directions of 15 directions (FIG. 4 (B)) and AR14 and AR16 directions (FIG. 4 (B)).

Further, the reinforcing metal fitting 18 has a body difference of 4 (base wheel 6).
On the other hand, nails are provided with nail holes H1 to H15, H29 to H33 and H, which are formed in the plate portions P1 to P4 and the body portion.
45-H49 (Fig. 2) to AR17 direction (Fig. 4 (A))
, AR18 direction (FIG. 4 (A)), AR19 and AR
It is possible to drive from four directions of 20 directions (FIG. 4 (B)) and AR21 and AR21 directions (FIG. 4 (B)).

As a result, the reinforcing metal fitting 18 is fixed to the through pillar 3A.
It is possible to drive nails intensively near the joint between the body and the body difference 4 (base wheel 6), and in addition, the nail on a certain surface may come off due to an external force acting in a certain specific direction. Also, the nails on each side do not come off at the same time, and the through columns 3A and the body gap 4 (base wheel 6) are connected to each other by the reinforcing metal fittings.
It is possible to prevent the joint portion with and from being separated from each other by a certain amount or more.

Thus, the through pillar 3A and the body difference 4 (base wheel 6)
If the reinforcing metal fitting 18 is fixed to the joint portion with, since the reinforcing metal fitting 18 can support the external force acting on the joint portion as a surface, it is tenacious with respect to the tensile force and the extension force, and the bonding strength is increased. It can be made even stronger.

In the first embodiment described above,
The case where the reinforcing metal fitting 18 is used at the joint between the body difference 4 (base wheel 6) having a thickness of 10.5 [cm] × 10.5 [cm] and the through column 3A has been described, but the present invention is not limited to this. Ten.

In this case, for example, in FIG. 5 in which parts corresponding to those in FIG.
3, IM4, IM7 and IM8 may be fixed as ridge lines without bending.

As described above, if the virtual lines IM3, IM4, IM7 and IM8 are not bent as ridge lines according to the thickness of the body difference 4 (base wheel 6), 10.5 [cm] × 10.5
It is possible to use the reinforcing metal fittings 18 even if the body difference is 4 (base wheel 6) not having a thickness of [cm], and it is possible to perform on-site matching according to the thickness of the body difference 4 (base wheel 6). .

Further, in the above-mentioned first embodiment,
The case where the reinforcing metal fitting 18 is used at the joint portion between the body difference 4 (base wheel 6) and the through column 3A, that is, the joint portion where the body difference 4 (base wheel 6) is joined at a right angle to the through column 3A has been described. However, the present invention is not limited to this, and the reinforcing metal fitting 18 may be used at a joint portion where a pair of wood pieces are joined vertically to the through column. In short, in a wooden building such as a wooden house, it is sufficient if it is a joint portion in which a pair of timbers are almost vertically joined to a predetermined position except one end and the other end of the predetermined timber.

A nail hole H110 is drilled at the center position of H109 to H109.

In this way, each nail hole H70 of the reinforcing metal fitting 19 is
~ H110 is provided at a position corresponding to the area of each plate portion P9 to P12 and the main body portion, and this position is about several mm in the thickness of the wood at the joint portion between the base 2 and the pipe column 3B. It is provided so that the nail can be driven even if there is an error.

Therefore, each of the nail holes H70 to H110 can surely hit the nail even when the thickness of the timber at the joint portion has an error of about several mm.

Further, each nail hole H70 to H of the reinforcing metal member 19
The plate 110 is formed by nailing each plate portion P9 by maintaining the positional relationship of each vertex of the isosceles triangle.
~ Equalize the pressure distribution on P12 and the body.

Therefore, each of the nail holes H70 to H110 can prevent all nails from being pulled out by an external force acting in a certain specific direction, and thus each plate portion P9 to P12 by the nails and the main body portion. Joint part (base 2
And the fixation to the tube column 3B) can be strengthened.

As a result, an operator who drives a nail into the reinforcing metal fitting 19 simply drives the nail into each of the nail holes H70 to H110, and the reinforcing metal fitting 19 is attached to the joint portion between the base 2 and the pipe column 3B. Can be firmly fixed.

Thus, the reinforcing metal fitting 19 can avoid the complexity of the nailing work.

According to the above configuration, the reinforcing metal fitting 19 is
The joint portion between the base 2 and the pipe column 3B that is abutted orthogonally to the base 2 can be reinforced in multiple directions so as to wrap it in both the vertical direction and the horizontal direction.

Therefore, when an external force acts in the direction of compressing the reinforcing metal fitting 19 in the longitudinal direction, the reinforcing metal fitting 19
Unlike a conventional rigid body, it can absorb an external force in a form of deformation, and when the external force acts in a direction extending with respect to the longitudinal direction of the reinforcing metal fitting 19, the tensile force of the thin iron plate is tenacious. Appears and can resist external force.

As a result, the reinforcing metal fitting 19 can realize the reinforcement that can withstand a large external force such as an earthquake without the joint portion between the base 2 and the pipe column 3B shifting or coming off. Thus, the "structural stickiness" at the joint between the base 2 and the pipe column 3B can be strengthened.

By the way, the reinforcing metal fitting 19 has nails for the pipe column 3B and nail holes H76 to H81, H87 to H93 and H which are formed in the plate portions P11, P12 and the main body portion.
AR23 direction from 99 to H110 (FIG. 5) (FIG. 6)
(A)), AR24 direction (FIG. 6 (A)), AR25
It is possible to drive from four directions, the direction (FIG. 6B) and the AR26 and AR27 directions (FIG. 6B).

The reinforcing metal fitting 19 has nails for the base 2, nail holes H70 to H75, H82 to H85, and H94 to which holes are formed in the plate portions P9, P10 and the main body portion.
From H98 (Fig. 5) to AR28 direction (Fig. 6 (A)), A
It is possible to drive from three directions of R29 direction (FIG. 6 (B)) and AR30 and AR31 directions (FIG. 6 (A)).

As a result, the reinforcing metal fitting 19 can drive nails in the vicinity of the joint between the pipe column 3B and the base 2 in a concentrated manner, and the nails on a certain surface can be removed by the external force acting in a certain specific direction. Even if the nails come off, the nails on the respective surfaces do not come off at the same time, and it is possible to prevent the joints between the pipe columns 3B and the base 2 which are connected to each other by the reinforcing metal fittings from being separated from each other by a certain amount or more.

If the reinforcing metal fittings 19 are used to fix the joints between the pipe columns 3B and the base 2 in this way, the reinforcing metal fittings 19 can support the external force acting on the joints as a surface. Further, it is tenacious with respect to the tensile force and the extension force, and the bonding strength can be further strengthened.

In the second embodiment described above,
For example, the case where the reinforcing metal fitting 19 is used at the joint between the end of the base 2 such as the entrance and the pipe column 3B has been described, but the present invention is not limited to this, and the point is that in a wooden building such as a wooden house, It suffices as long as it is a joining portion in which a pair of timbers are joined substantially vertically at predetermined positions except one end and the other end of the predetermined timber.

(4) Third Reinforcing Metal Fitting The third reinforcing metal fitting 20 is a joint portion where the first wood and the second wood are orthogonal to each other, and a joint portion to which a relatively large weight is applied. It is suitable for use in.

As shown in FIG. 8, the reinforcing metal member 20 has long sides L5 and L6 each having a length of 50 [cm] and short sides S5 and S6.
Is a rectangular iron plate having a length of 6 [cm] and a plate thickness D3 of 3 [mm], and is processed into an L shape.

In addition to this, the reinforcing metal fitting 20 has the long side L
5 or L6 and the first plate portion 20A on one end side and the second plate portion 20B on the other end side from the L-shaped boundary of the L-shaped main body portion 24.
Between the upper side and the lower side 29.
A trapezoidal holding portion 25 having a height of 5 cm, a height of 14 cm and a thickness of 3 mm is welded.

As a result, the reinforcing metal fitting 20 has the holding portion 25.
The L-shape can be held so as not to be deformed.

In the above structure, the third reinforcing metal fitting 2
As shown in FIG. 9, 0 is applied to, for example, an L-shaped joint portion in which the body difference 4 (base wheel 6) is in contact with the through column A at right angles.

The reinforcing metal fitting 20 is aligned along the L-shaped joint so that the side surface one end of the body difference 4 (base wheel 6) and the holding portion 25 are parallel to the side surface one end of the through column 3A. .

Further, the reinforcing metal fitting 20 is fixed to the joint portion between the through column 3A and the body difference 4 (base wheel 6) by a nail in the state of being aligned with the spot.

In this nailing work, the reinforcing metal fitting 20 is used.
Is pre-drilled with a nail hole that allows the operator to specify a position where the nail can be firmly fixed.

Nail hole position in the case of this embodiment (FIG. 8)
In the L-shaped main body portion 24 of the reinforcing metal fitting 20,
Nail holes H125 and H130 are formed at the center position of the plate portion 20A and the center position of the second plate portion 20B, and the nail holes H125 and H130 are two sides of each vertex of the isosceles triangle shape. As the vertices that are joined to each other, each nail hole H121 to the position that determines the shape of the isosceles triangle.
H124 and H126 to H129 are provided.

As described above, each nail hole H12 of the reinforcing metal fitting 20 is
1 to H130 are provided at positions corresponding to the area of the L-shaped main body portion 24 of the reinforcing metal fitting 20.
It is provided so that a nail can be driven even if there is an error of about several mm in the thickness of the timber at the joint between A and the body difference 4 (base wheel 6).

Therefore, each of the nail holes H121 to H130 can surely hit the nail even when the thickness of the timber at the joint portion has an error of about several mm.

Further, each nail hole H121 to the reinforcing metal fitting 20 is formed.
The H130 is bored while maintaining the positional relationship of each vertex of the isosceles triangle, so that the pressure distribution exerted by the nail on the L-shaped main body of the reinforcing metal fitting 20 is made uniform.

Therefore, each of the nail holes H121 to H130 can prevent all nails from being pulled out by an external force acting in a certain specific direction, and thus, the L-shaped main body portion of the metal member 20 for reinforcing by nails. It is possible to strengthen the fixing of the joint portion 24 (through column 3A and body difference 4 (base wheel 6)).

As a result, the worker who drives the nail into the reinforcing metal fitting 20 simply hammers the nail into each of the nail holes H121 to H130 to pass the reinforcing metal fitting 20 through the pillar 3A and the body gap 4 (base wheel 6). It can be firmly fixed to the joint part with.

Thus, the reinforcing metal fitting 20 can avoid the complexity of nailing work.

According to the above construction, the reinforcing metal fitting 20 is
When an extremely large external force acts in the direction of the arrow A, the thick iron material is fixed along the joint between the through column 3A and the body difference 4 (base wheel 6), so that the large fluctuation of the through column 3A is suppressed. , The through column 3A is prevented from tilting in the direction of arrow A (FIG. 8).

At this time, the reinforcing metal fitting 20 is deformed in shape of the L-shaped main body portion 24 of the reinforcing metal fitting 20 due to an extremely large external force acting in the direction of arrow A by the welded holding portion 25. By preventing the L-shaped angle from changing), it is possible to further suppress the extremely large fluctuation of the through column 3A and further prevent the through column 3A from tilting in the arrow A direction.

In the case of the wooden house of this embodiment, a large weight is applied to the joint portion between the through column 3A and the body difference 4 as compared with other joint portions, so that both the reinforcing metal fittings 18 and 20 are attached. It is provided (Fig. 2).

In this case, since the reinforcing metal fitting 20 is made of a thick iron material, it is possible to suppress an extreme fluctuation in the direction of the arrow A, thereby making the reinforcing metal fitting 18 effectively function as a reinforcement. That is, since the reinforcing metal fitting 18 is made of a thin iron material, the softness and tenacity of the metal can be utilized. However, when an extremely large external force acts on the joint portion, the external force acting on the joint portion may be larger than the tenacity of the reinforcing metal fitting 18 at the joint portion because of the thinness of the reinforcing metal fitting 18. Will end up. At this time, the reinforcing metal fitting 18 does not function as reinforcement.

Therefore, the reinforcing metal fitting 20 can suppress an extremely large external force, and thus the reinforcing metal fitting 18 can effectively function as a reinforcement.

Thus, the through pillar 3A and the body difference 4 (base wheel 6)
By providing both the reinforcing metal fittings 18 and 20 at a joint portion such as a joint portion to which an extremely large load is easily applied, even if an extremely large external force is applied to the joint portion, the reinforcing metal fitting 20 is provided. Suppresses an extremely large external force,
As a result, the function as reinforcement by the reinforcing metal fitting 18 can be made effective.

Incidentally, in the above-mentioned third embodiment,
The case where the reinforcing metal fitting 20 is fixed to the joint portion between the through column 3A and the body difference 4 (base wheel 6) has been described, but the present invention is not limited to this, and for example, the joint portion between the tube column 3B and the body difference 4 ( 2) etc. may be used. In short, it can be used for a joint portion where a pair of woods are joined at a right angle.

Further, in the above-mentioned third embodiment,
Although the case where the reinforcing metal fitting 20 is attached along the joint portion having the L shape has been described, the present invention is not limited to this, and as shown in FIG.
You may make it fix so that it may be covered.

Incidentally, at the nail hole position in the case of this embodiment, the upper base U1 is formed in the holding portion 25 of the reinforcing metal fitting 20.
A nail hole H141 is bored inward from the center position by a predetermined length and at a right angle to the upper base U1. , Nail holes H142 and H143, H144 and H145 are formed at positions that determine the shape of the isosceles triangle. Also, nail holes H142 and H
143 is bored in parallel with the hypotenuse D1, and nail holes H144 and H145 are bored in parallel with the hypotenuse D2.

Therefore, the joining portion fixed by covering the reinforcing metal fitting 20 is fixed with nails from three directions.

As a result, it is possible to prevent all nails from being pulled out by an external force acting in a certain specific direction, and thus, a metal fitting for reinforcing a joint portion in which a pair of lumbers are joined at a right angle by the nails. The fixation of 20 can be strengthened.
