[0002]

TECHNICAL FIELD The present invention relates to a reinforcing metal fitting suitable for strengthening the structure of a wooden house or the like. It also relates to a wooden building constructed using these metal fittings.

[0003]

2. Description of the Related Art A conventional frame construction method is one of the typical construction methods for wooden houses. The conventional frame construction method is a traditional Japanese construction method and is one of the most commonly used construction methods at present.
In this conventional frame construction method, the foundation, columns and beams are used as a frame to support the force acting in the vertical direction of the building, and the earth-painted walls, braces, and bearing walls that are placed to surround them support the horizontal force. It supports the force acting in the direction. In addition, today, a device is added to the joint between the foundation and the pillar to increase the strength of the joint. Generally, a reinforcing material of this type is made of an iron material having a thickness of 3 [mm] and a width of 3 [cm] processed into a rod shape or an L shape. FIG. 12 shows an example of a metal fitting used as this type of reinforcing material, and FIG. 13 shows an example of attachment.

[0004]

By the way, this type of metal fitting is mainly intended to support the external force acting on the joint with the strength of iron. Therefore, a relatively thick iron material is used for the metal fitting. However, since it is so durable, there is a problem that if the metal fittings are deformed and attached according to the actual conditions of the work site, they cannot be used anymore, and the parts that can be reinforced are practically limited. Especially in the attic and other areas where many columns and beams are concentrated, the members crossed intricately, and even when using commercially available reinforcements, it was often impossible to use them due to slight steps or other members obstructing them. .

Therefore, in general, only such a part needs to be nailed, and in most cases, reinforcement using this kind of reinforcing material has not been made special. However, from the viewpoint of preparing for a disaster, it is necessary to reinforce these parts, and there is a demand for a reinforcing material that can be easily attached to such parts at a construction site. Also, although a relatively 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 considerably smaller than the width of the pillar (about 10 cm), It was still insufficient from the viewpoint of reinforcing the joint of the frame.

The present invention has been made in view of the above points, and an object thereof is to propose a safe wooden building which is harder to collapse than before and a reinforcing metal fitting for realizing the same.

[0007]

In order to solve the above problems, the present invention provides a metal fitting for reinforcing a wooden building,
A rectangular iron plate with a thickness of 1 mm or less,
Among the iron plates, one having a notch extending from one side to almost the center of the iron plate is used. Similarly, as a metal fitting for reinforcing a wooden structure, a rectangular iron plate having a thickness of 1 [mm] or less, which is bent at a right angle approximately in the middle in the longitudinal direction, is used.

Since the iron plate used for the reinforcing metal fitting has a thickness of 1 [mm] or less, it can be easily shaped according to the shape of the object to be attached and can be attached so as to be wound around the object to be attached. it can. Moreover, when an external force is applied to the object to be attached, the reinforcing metal fitting is a thin film, so that the reinforcing metal fitting is tenacious against pulling force and can absorb the external force by deformation. This makes it possible to avoid a momentary collapse.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

(1) Skeleton of Wooden House FIGS. 1 and 2 show a general skeleton structure of a two-story wooden house. In a wooden house, timber fixed to a concrete foundation 1 with anchor bolts is used as a base 2, and the base 2
It is designed to be built on the pillar with the pillar 3 as the vertical axis. There are two types of pillars 3 which are through pillars 3A arranged at the main parts of the respective corners and tube pillars 3B arranged according to the floor plan of the room, and are properly used according to the structure of the building. Attached to these pillars 3 as the horizontal axis is the body difference 4, the second floor beam 5,
Beams such as pedestals 6, eaves girders 7 and shed beams 8.

In the case of the wooden house of this embodiment, the balcony joist 9 is fixed to the body difference 4, the second floor beam 5 and the pedestal 6, but this balcony joist 9 is provided to form the balcony on the second floor. It is prepared. In addition to this, at the four corners of each floor, a flooding platform 10 is provided for the purpose of preventing twist in each floor plane.
A staking beam 11 is provided, and a brace 12 is provided to prevent twisting of the wall. These various members form a shaft assembly of the first floor portion and the second floor portion.

On the other hand, the roof 13 is supported by the bundle 14, the purlin 15, and the erection timber 16. Here, the bundle 14 is a pillar fixed to the shed beam 8 with a hook, and a shorter one is used as the roof 13 is closer to the eaves so that the roof 13 is inclined. Further, the purlin 15 connects the pair of bundles 14 located at opposite positions to each other so as to support the erection square members 16. In the case of this embodiment, the bundles 14 are fixed to each other by a reinforcing material called a shed 17 so that the bundles 14 do not fall sideways.

The above is the schematic structure of the wooden house constructed by the conventional frame construction method. In this embodiment, the reinforcing metal fittings 18 and 19 are provided at the connecting portions of the respective members in order to strengthen the structural rigidity.
Is installed. The reinforcing metal fittings 18 and 19 are both made of an iron plate having a zinc-plated surface. The structure and use of each of the reinforcing metal fittings 18 and 19 will be described in the next section. By the way, the structural stickiness means the ability to withstand without being broken even if it receives a force and is deformed, and the reinforcing metal fitting described in this embodiment has this idea as a basic idea.

(2) Structure of Reinforcing Metal Fitting (2-1) Reinforcing Metal Fitting 18 FIG. 3 shows the reinforcing metal fitting 18. The reinforcing metal member 18 is used for connecting portions of relatively thick square members, such as a joint portion between a base and a pillar or a joint portion between pillars and a pillar, and a thin iron plate having a rectangular shape is formed near the center in the longitudinal direction. The structure is bent almost at a right angle. In the case of this embodiment, the reinforcing metal fitting 18
Is a rectangular iron plate having a thickness of 0.5 [mm], a length of 294 [mm], and a width of 73 [mm], which is bent at a right angle at approximately the center in the longitudinal direction. Further, the reinforcing metal fitting 18 is provided with four nail holes 18A at each of the four corners and the central position of each surface, so that a total of five nail holes 18A are provided to serve as a guide when nailing.

As described above, since the reinforcing metal fitting 18 is a very thin iron plate having a thickness of 0.5 [mm], it can be easily deformed by human force, and it depends on the condition of the member to be mounted. The bending angle can be freely changed. As described above, the reinforcing metal fitting 18 utilizes the softness of iron so that it can be transformed into an optimum shape according to the state of the object to be reinforced. Therefore, the reinforcing metal fitting 18 can be attached to a portion which is not attached because it is too strong and cannot be deformed like the conventional reinforcing metal fitting. At this time, the reinforcing metal fitting 18 absorbs lateral and vertical forces acting on the pillar or the like from the outside as deformation of the metal fitting itself.

In the case of a conventional hard metal fitting, when a force is applied from the outside, the external force may be transmitted to the head portion of the nail as it is, and the force may act in the direction of pulling out the nail. In the case of the reinforcing metal fitting 18 according to this embodiment, since the nail is stronger, there is no fear that the nail will come off. In addition, even if the two members, which have been winged and fixed to each other, come out of alignment, the reinforcing metal fitting 18 maintains the connection between the two members by the pulling force. Therefore, it is possible to prevent the two members from being separated at a time more than a certain distance. Therefore, the risk of collapse can be reduced and the safety of the wooden house can be improved.

Further, in the case of the reinforcing metal fitting 18, even when there is a step on the mounting surface, the reinforcing metal fitting 1 is provided along the step.
It is also possible to deform 8 and drive the nail deeply with no gap between the reinforcing metal fitting 18 and the mounting surface. Since the nail can be driven deeply in this way, the joint strength of the joint portion can be further increased. Furthermore, since this reinforcing metal fitting 18 is very thin, 0.5 [mm],
The existence itself does not interfere with other members, and it is possible to easily attach other members by stacking them on the reinforcing member 18 for reinforcement.

Since the conventional metal fitting has a thickness of about 3 mm, it is necessary to process the member to be attached in order to attach other members. On the other hand, since the reinforcing metal fitting 18 is very thin (0.5 mm), it is possible to easily apply a nail to a portion where no nail hole is formed to reinforce it. Also in this respect, the degree of freedom is high and it is convenient as compared with the conventional metal fittings. By using the reinforcing metal fittings 18 in this way, the strength of the wooden house can be further increased, and the risk of the joints of the columns and beams being destroyed by external forces is reduced even during a disaster, and the safety of the wooden house is improved. be able to.

(2-2) Reinforcing metal fitting 19 FIG. 4 shows the reinforcing metal fitting 19. This reinforcing metal fitting 19 is suitable for use in a connecting portion between the pillar 3B and the beam 8 and a connecting portion between the erection square member 16 and the eaves girder 7 and the like, and a notch is formed on one side of a rectangular thin iron plate. It will be attached structure. In the case of this embodiment, the reinforcing metal member 19 is a rectangular iron plate having a thickness of 0.5 [mm], a length of 170 [mm] and a width of 98 [mm], and is parallel to the short side from the middle of the long side. It is characterized in that it has a notch of 49 [mm]. Due to the presence of this notch, the reinforcing metal fitting 19 can be bent not only on an imaginary line parallel to the short side but also freely on an imaginary line parallel to the long side, so as to wrap the joining member. It is designed to be multifaceted.

The length of the reinforcing metal fitting 19 in the width direction of 98 [mm] is narrower than the width of a square timber used in a wooden house, and can be attached to any square timber. Further, the reinforcing metal fitting 19 is formed with nail holes 19A at four corners of two areas A-C-F-D and D-F-I-G sandwiching the notch, respectively, when nailing the nail. It is designed to serve as a guide. Here each nail hole 19A
Is centered at 18 mm along each side from the four corners of each area, and the diameter of the nail hole 19A is 4 mm.
It is set to [mm].

As with the reinforcing metal fitting 18 described above, the reinforcing metal fitting 19 is a very thin iron plate having a thickness of 0.5 [mm], so that it can be easily deformed by human force and is a member to be attached. The bending angle can be freely changed according to the state of. An example of attachment of the reinforcing metal fitting 19 is shown in FIGS. Note that the notations A, B, C ... I in FIGS. 5 to 10 indicate the reinforcing metal fitting 1 shown in FIG.
9 shows the same positions as A, B, C ... I attached to No. 9, and is a mark for explaining how to bend.

First, a first mounting example is shown in FIG. This example is an example in the case of reinforcing a joint portion where the heights of the surfaces of the columns 20 that are the vertical axis and the beam 21 that is the horizontal axis are even. In this case, the reinforcing metal fittings 19 may be left in the same shape and nails may be driven at right angles to the square members. When there is a step at the joint between the surfaces of the column 20 and the beam 21, the reinforcing metal fitting 19 may be bent by hand or deformed with a hammer and attached. If the above-mentioned reinforcing metal fitting 18 is used at the corner between the column 20 and the beam 21, the strength of the joint can be further increased.

Next, a second mounting example is shown in FIG. In this example, the reinforcing metal fitting 19 is attached to the pillar 20 so as to be wound, and is bent and attached so that the line segment B-E becomes a mountain line. When the nail is deformed and attached in this manner, the nail can be driven from two directions orthogonal to each other. In this case, the nails can be intensively driven in the vicinity of the joint between the column 20 and the beam 21, and the reinforcing metal fitting 19 can support the force acting on each member as a surface, so that the nail can be fixed only by the nail. It is possible to add a structural tenacity as compared with the case of performing. Further, since the shape of the portion where the nail is hit is rectangular and a relatively large area can be secured, the stickiness against external force can be strengthened.

A third mounting example is shown in FIG. In this example, the line segment DE is bent so that it becomes a mountain line, and the line segment B-
This is an example of bending and attaching so that E becomes a valley line. When deformed and attached in this way, the nail can be driven from three directions and the external force from three directions can be supported by the surface. That is, the structural tenacity can be strengthened in the three directions, and the destruction can be prevented from proceeding at once. 4th
An example of attachment of the is shown in FIG. In this example, the line segment E-H is bent so that the line segment DE is a valley line, and the line segment B-E is bent so that the mountain line is attached. Here is an example. If the nails are deformed and attached in this way, the nails can be driven from three directions, and external forces in the three directions can be supported by the respective surfaces. Pillar 2
Since nails can be struck from two directions with respect to each of 0 and the beam 21, it is possible to maintain the state in which each member and the reinforcing metal fitting 19 are connected to each other on either surface.

A fifth mounting example is shown in FIG. This example is an example of reinforcing the joint portion of the beam 21 and the erection square member 23 in the attic portion, and when the line segment DE is bent as a valley line and the line segment BE is bent as a mountain line. Is an example of. When attached in this way, an external force acting on the joint between the beam 21 and the erection square member 23 can be supported by the surface. Further, even when an external force acts in a direction in which the beam 21 and the erection square 23 are separated from each other, the surface B-C-F-E mounted so as to be wound around the erection square 23 and the erection square 23 are joined together. Since the force does not relax, it is possible to prevent the beam 21 and the erection square member 23 from being pulled apart at once. This also applies to the case of FIG. 10, which is the sixth example of attachment. By the way, in the example of FIG. 10, the line segment E-D is transformed so as to become a valley line,
In this example, the line segment HE is deformed and attached so as to be a mountain line. Also in this case, the same effect as that of the fifth mounting example can be obtained.

(3) Other Embodiments In the above-mentioned embodiments, the size and shape of the reinforcing metal fitting 18 have been described with reference to FIG. 3, but the present invention is not limited to this, and other lengths and widths may be used. You may use the thing of the value of. Further, in the above-described embodiment, the case where the reinforcing metal fitting 19 shown in FIG. 4 is used has been described, but the present invention is not limited to this, and as shown in FIG. 11, two nail holes on the cut side are measured. The present invention can also be applied to the case of a total of six instead of four. Further, the numbers and positions of the nail holes 19A and 19B are not limited to these examples. It can also be applied when no nail holes are provided. Even if the nail hole is not provided, the reinforcing metal fitting 19 has no problem because the hole can be opened by thinly nailing.

Further, in the above-mentioned embodiment, the thickness of the iron plates used for the reinforcing metal fittings 18 and 19 is 0.5 respectively.
Although the case of [mm] has been described, the present invention is not limited to this, and a thickness of about 1 [mm] may be used if the thickness can be relatively easily shaped and a predetermined strength can be guaranteed. . The thickness may be 0.5 mm or less, 0.3
[Mm] is more preferable. For this reason, it is possible to use a thin film having a thickness of about 0.1 mm. Further, in the above-mentioned embodiment, the case where zinc is used as the plating agent has been described, but the present invention is not limited to this, and other plating agents may be used.

In the above-described embodiment, the case where the two types of reinforcing metal fittings 18 and 19 are used in combination in the wooden house has been described, but the present invention is not limited to this, and only one of them is used. Can also be applied. Even if any of the reinforcing metal fittings is used, the structural stickiness of the wooden house can be strengthened as compared with the conventional one, and a wooden structure with higher safety can be realized.

[0029]

As described above, according to the present invention, the thickness is 1
By using an iron plate of [mm] or less as a material, it is possible to realize a reinforcing metal fitting that can easily be attached to a place that could not be attached with a conventional reinforcing material. Further, when an external force acts, the reinforcing metal fitting itself is deformed to absorb the external force acting on the object to be attached, and it is possible to realize a reinforcing metal fitting having a structural stickiness that can avoid the total destruction of the reinforcing part. .
