Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for joining wooden members such as pillars and beams, girders, braces, and foundations in wooden structures, or joining wooden members such as chimpan and rakubari, chimpanzees and louvers. It relates to a building metal fitting to be used.

[0002]

2. Description of the Related Art Conventionally, in traditional wooden frame construction in Japan, a unique frame construction method has been adopted for joining and assembling wooden members. However, in this traditional frame construction method, in addition to complicated frame work, various special processing and working methods are required for the joints, joints, etc. of the wooden members to be joined, and Requires highly skilled carpenters and other workers, and since these works were carried out at the actual construction site for each building, work efficiency was extremely poor, and in combination with the recent lack of manpower, the construction period was long. And various problems such as higher cost and higher cost.

Therefore, in recent years, in order to solve such a problem, by using a joining metal fitting for joining the wooden members, the wooden members and the joining structure thereof are standardized, and it is not necessary or extremely necessary to process the joints and joints. By simplifying and performing all necessary processing operations in the factory centrally,
At the construction site, a new wooden frame construction method has been adopted in which these processed wooden members are joined using joining metal fittings.

According to the wooden frame construction method using such joining metal fittings, no special technique or working work is required,
Since the frame work is also extremely simple and easy, it is possible to perform the frame work efficiently at the construction site. Examples of the joining metal fittings used in this type of wooden frame construction method include, for example, JP-A-3-176259 and JP-A-5-14.
There is a joining metal fitting described in Japanese Patent Application Laid-Open No. 8912 or JP-A-5-295799.

According to Japanese Patent Laid-Open No. 3-176259, a steel pipe fitting is arranged at a joint portion of a column, and a shaft bolt fitted to a beam, a girder or the like to be joined to bolt holes formed in four directions of the steel pipe fitting is tightly connected. By doing so, a wooden three-dimensional frame joining method has been proposed in which each wooden member can be joined easily.

Further, in Japanese Patent Laid-Open No. 148912/1993, a metallic core material, a support plate welded to the core material, and a mounting member on the board are inserted into a wooden member such as a pillar, a beam, or a girder, and the core material is used. There has been proposed a structural metal fitting for a wooden building in which a wooden member is reliably joined by allowing a pin to penetrate through a metal fitting such as the above.

Further, according to the wooden structure frame structure and the frame structure disclosed in Japanese Patent Laid-Open No. 5-295799, the hook formed at one end of the hook plate is locked in the notch formed in the pillar. The other end of the hook plate is inserted into an insertion groove formed in a beam, a girder or the like and fixed with bolts, whereby the wooden members are easily and surely joined.

[0008]

However, in the wooden three-dimensional frame joining method described in Japanese Patent Laid-Open No. 3-176259, only one shaft bolt is used for each wooden member such as each beam and girder to be joined to a column. Since it was supported by, there was a problem that the strength was weak and the frame work became difficult. Also, the shaft bolt protruding upward from the pillar and the nut for fixing the upper pillar were tightened by inserting a spanner or the like into the small hole formed in the upper pillar, and this tightening work was extremely inconvenient. There was also a problem that the tightening force was insufficient.

Further, in the structural hardware of a wooden building described in Japanese Patent Laid-Open No. 148912/1993, with respect to the core material,
A separate support plate and plate-shaped mounting body were formed each time according to the direction, angle, size, etc. of the beam, girder, etc. to be joined and fixed by welding, etc.
There is a problem that it takes time to manufacture the metal fittings, and the range of use is narrow and the versatility is lacking.

On the other hand, in the wooden frame construction structure and the frame assembly disclosed in Japanese Patent Laid-Open No. 5-295799, the notches are formed directly in the pillars and the hooks of the hook plates are locked, so that the notches are formed. However, there is a problem in that there is a high risk that the notch will be easily damaged by the hook, and that the joint strength is insufficient due to this.

The present invention has been proposed in order to solve the problems of each of the conventional techniques described above, and is composed only of a metal fitting having a simple, small-sized and lightweight structure, and a simple joint to a wooden member. Can be used to join all wood components by simply processing
The purpose of the present invention is to provide a metal fitting for construction that enables strong and firm joining of wooden members, as well as easy and reliable framing work.

[0012]

[Means for Solving the Problems] In order to achieve the above-mentioned object, a metal fitting for construction according to the present invention is a metal fitting used for joining wood members in a wooden building, and includes a seat plate and one surface side of the seat plate. And a bolt which is inserted into one of the wooden members and is screwed into the fastening nut, and a surface of the seat plate opposite to the projected surface of the fastening nut. And a hole provided in the connecting plate, and a pin penetrating the hole of the connecting plate via a pin hole protruding in the other wooden member of the wooden members.

The hole provided in the connecting plate is an inverted gourd-shaped guide hole consisting of two large and small holes, and a pin penetrating the guide hole is larger than the connecting portion width of the two large and small holes. It is a tapered pin having a small diameter portion and a small diameter portion.

Further, the holes provided in the coupling plate may be support holes having a long hole shape, or adjustment holes having, for example, a fan shape having one side of an arc, or two or more of these support holes and the guide holes. It is configured by a combination of holes.

Further, the seat plate is configured to engage with a seat hole formed in the one wooden member, and the bolt screwed to the fastening nut is composed of two bolts and The other bolt penetrates through a cross hole provided at the center of the bolt in the longitudinal direction to cross the bolt.

[0016]

According to the construction joining metal fitting of the present invention having such a structure, the pillar, the beam, the girder and the like can be joined only by engaging the connecting plate of the seat plate with the wooden member and driving the pin. Also, since the connecting pin is guided by the guide hole to easily position the pillar and the beam, the framing work can be performed very easily.

When a horizontal member such as a beam is joined to a vertical member such as a pillar, the seat plate engages with a seat hole formed in the pillar,
Since it is directly held by the pillar or the like, the load applied to the horizontal member such as the beam or girder is supported by the pillar or the like.

In order to firmly weld the seat plate 1, the fastening nut 2 and the joining plate 3, the other end of the fastening nut 2 engaged with the through hole 1a is connected to the joining plate 3 as shown in FIGS. It may be formed by projecting a little to the side, straddling the concave portion of the coupling plate 3 and straddling it integrally. By doing so, the seat plate 1, the fastening nut 2, and the connecting plate 3 are firmly and integrally fixed to each other. Further, in order to facilitate the insertion into the beam 200, the connecting plate 3 is obliquely cut at the lower end on the outer side (beam 200 side) in this embodiment.

In the vicinity of the outer end of the side surface of the connecting plate 3,
The guide hole 4 through which the connection pin 40 penetrates is provided through the connection pin hole 202 of the beam 200. The guide hole 4 has a hole 4a with a large diameter (thicker than the connecting pin 40) on the upper side, a hole 4b with a smaller diameter (approximately the same diameter as the connecting pin 40) on the lower side, and a hole 4b on the lower side with the upper side. It is located inside the hole 4a (on the side of the seat plate 1) and has a slightly inclined inverted gourd shape. The connecting portion of the upper hole 4a and the lower hole 4b is formed on the connecting pin 40. Wedge-shaped slope 40
The width is such that only a can pass through.

The guide hole 4 serves as a fixing hole for connecting the beam 200 and the connecting plate 3 by the connection pin 40 penetrating the lower hole 4b and, as will be described later, the beam 200.
It also functions as a positioning hole when joining.

Inclined portion 40a of the connecting pin 40 shown in FIG.
Is formed so that one end side is thinned in a wedge shape, but it is not limited to such a wedge shape as long as it can pass through the connecting portion of the guide hole 4, and may be, for example, a tapered shape. it can. Further, on the other end side of the connection pin 40, an orientation constant groove 40b indicating the orientation of the inclined portion 40a is provided to facilitate the work. The connection pin 40 is usually made of steel, but may be made of another material.

Further, the coupling plate 3 is provided with two support holes 3a through which the support pins 30 pass through the support pin holes 203 of the beam 200. In addition, in the case where the width of the horizontal member such as the beam 200 to be joined is large, the connecting plate 3 also becomes large according to the width, but in this case, the number of the support holes 3a also increases
On the contrary, when the width of the beam 200 is small and lightweight, the support hole 3a may be omitted or only one.

This support hole 3a passes through the support pin 30.
May have a diameter substantially the same as that of the support pin 30 so as to be in a press-fitted state, and in order to facilitate the alignment with the support pin hole 203 of the beam 200 as in the present embodiment, a play is made in the joining direction. It may have a long hole shape that is long in the horizontal direction so that it can be held. The support pin 30 penetrating the support hole 3a
Similarly to the connection pin 40, a steel-made one is usually used, but another material may be used.

The bolt 5 is penetrated through the pillar 100 from the surface opposite to the surface on which the seat plate 1 is mounted. The screw at the tip is screwed into the fastening nut 2, and the head serves as a stopper for the pillar. The outer peripheral surface of 100 is locked. The seat plate 1 is fixed to the pillar 100 by the bolts 5. In the present embodiment, the head of the bolt 5 is used as a stopper. However, in addition to this, a nut is screwed on a rod-shaped bolt having both ends without a head or screws formed on the whole, to form a stopper. You can also do it. In this case, as will be described later, the fastening nuts 2 are screwed on both ends of the bolt 5,
It is also possible to attach a joint fitting.

Next, the manner of use of the construction metal fitting of this embodiment having such a structure will be described with reference to FIGS. First, a concave seat hole 101 with which the seat plate 1 engages is previously formed on one surface of the pillar 100, and a bolt hole 102 penetrating from the center of the seat hole 101 to the back surface of the pillar 100 is formed. Then, the bolt 5 is inserted into the bolt hole 102, the seat plate 1 is inserted into the seat hole 101, and the bolt hole 10 is inserted.
While engaging the tightening nut 2 with the screw 2, the tightening nut 2 and the bolt 5 are screwed together and tightened. As a result, the seat plate 1 becomes the seat hole 1
In the state of being engaged with 01, the connecting plate 3 is in a state of protrudingly provided on the pillar 100. At this time, if the connecting plate 3 is rotated while pressing the end portions of the bolts 5, the bolts 5 can be easily tightened.

Further, after the bolt 5 and the fastening nut 2 are screwed together, the seat plate 1 is prevented from rotating by tightening a wood screw or driving a nail through the fixing hole 1b. It should be noted that, in general, these operations, the seat hole 101 of the pillar 100, the bolt hole 102, and the coupling groove 20 to the beam 200 are performed.
1. All the processing required for each wooden member, such as the processing of the support pin hole 202 and the connection pin hole 203, is performed in advance in a factory or the like with a good working environment. That is, by doing so, the work at the construction site is only the work of joining the pillar 100 and the beam 200 to which the metal fittings are attached, and the work efficiency can be improved.

Next, at the construction site, first, referring to FIG.
As shown in (a), the columns 100 and the beams 200 are aligned with play, and the coupling plate 201 of the seat plate 1 attached to the columns 100 is provided with the coupling grooves 201 provided in the beams 200. Engage. Next, as shown in FIG. 3B, the connection pin 4 is inserted through the connection pin hole 202 on the side surface of the beam 200.
0 in the hole 4a above the guide hole 4 of the connecting plate 3
The part a is penetrated. This makes the beam 200 the pillar 1
It will be temporarily supported by 00.

In this state, the beam 200 is moved downward and the pillar 100 is
The guide pin 4 is moved to the side, and the connecting pin 40 is moved from the upper hole 4a of the guide hole 4 to the lower hole 4b while being guided by the guide hole 4.
The play between the pillar 100 and the beam 200 is eliminated, and in this state, the connection pin 40 is driven and penetrated (state of FIG. 3C). As a result, the connecting pin 40 cannot move to the upper hole 4a and is firmly fixed to the lower hole 4b.
00 to the connecting plate 3. Then, if necessary, the support pins 30 are sequentially driven through the support pin holes 203 on the side surfaces of the beam 200 to further strengthen the connection between the beam 200 and the connecting plate 3.

In this state, the pillar 100 and the beam 200 are fixed and the joining is completed. Pillar 10 joined in this way
0 and the beam 200, the seat hole 101 serves as a chin rest to hold the outer peripheral edge portion of the seat plate 1, so that the load applied to the beam 200 is directly supported by the column 100 via the chin rest of the seat hole 101. It As a result, the strength is much higher than when the load applied to the beam 200 is applied only by the metal fittings. When play is generated in the joint due to contraction or expansion of the beam 200, if the connecting pin 40 is further driven, the inclined portion 40a of the connecting pin 40 serves as a tightening allowance and can be further tightened.

As described above, by using the construction metal fitting of this embodiment, the beam 200 and the pillar 100 can be temporarily supported by the connection pin 40, and the bolt (tightening nut) or the like can be used at the construction site. Since it does not require any tightening work, the frame work can be extremely easily performed even at a construction site where the working environment is bad.

Further, since no special machine or the like is required at all through the frame work process, even a general craftsman who does not have a factory, equipment or the like can perform the processing on site and can widely use it. Furthermore, only the simple processing such as the above-mentioned seat hole 101 and the connecting groove 201 is required for the joint processing of the pillar 100 and the beam 200, and the metal fittings are exposed at the joint portion of the wooden members, which spoils the appearance of the building. There is no such thing.

As shown in FIG. 4, the metal fittings of this embodiment can be attached to both sides of the pillar 100 facing each other, as required by the structure of the building. That is, the pillar 10
0 is provided with seat holes 101 on both sides, and the tightening nut 2 fixed to the seat plate 1 is screwed to both ends of the bolt 5. In this case, the seat plates 1 on both sides are pulled at the center of each other, whereby the mounting strength of the seat plate 1 can be further increased. Further, particularly when the beam 200 is large and heavy, it is possible to provide a plurality of main joining fittings in one direction as shown by the imaginary line in FIG.

Next, another embodiment of the building metal fitting of the present invention will be described with reference to FIGS. FIG. 5 shows an exploded perspective view of the joint fitting of this embodiment. In addition, FIG. 6 is a partial cross-sectional plan view showing a state in which the wooden members are joined using the joining fitting of the present embodiment.

As shown in these figures, in the joint fitting of this embodiment, the bolt in the above-mentioned embodiment is composed of two bolts 10 and 11, and a cross hole is formed at the center of one bolt 10 in the longitudinal direction. 10a is bored and the cross hole 10
By forming the other bolt 11 through a, it is formed so as to intersect at an angle of 90 degrees. And
The pillar 100 has seat holes 101 facing the four outer peripheral surfaces, respectively.
And the bolt holes 102, so as to communicate with each other by intersecting from the center of each seat hole to the inner center of the pillar.
103 is formed in advance.

As the bolt 10 having the cross hole 10a, in this embodiment, as shown in FIG. 7A, the bolt is screwed to both ends of a nut-shaped member having the cross hole 10a. Is fixed by welding or the like, but is not limited to this, and if it has at least cross holes 10a and bolts are formed at both ends, as shown in FIG. You can also do it.

As a result, each bolt hole 102, 103
The bolts 10 and 11 inserted in the column cross at the inner center of the pillar 100, and the fastening nut 2 is screwed to the end of each bolt to attach the seat plate 1 to the four outer peripheral surfaces of the pillar 100. be able to.

As still another embodiment of the building metal fitting of the present invention, the shape of the connecting plate 3 is, for example, as shown in FIG. 8, a lower side (FIG. 8 (a)) and an upper side (FIG. 8 ( b)), or both upper and lower sides (FIG. 8 (c)) and the like may be bent by 90 degrees and extended. According to the joining metal fitting shown in this embodiment, in addition to joining vertical members such as columns, beams, and girders, and transverse members, diagonal members such as stairs and braces can be joined. Further, as shown in FIG.
The present invention can also be applied to joining various wooden members such as a diagonal member having a different joining angle such as the stairs 301, the joint 300 and the braces (not shown).

In the case of joining wooden members having different joining angles, for example, columns and braces, joints and braces, the connecting plate 3 is formed with, for example, a fan-shaped long hole with one side having an arc shape. It is also possible to use the adjustment hole 3b for adjusting the angle. That is, in this case, as shown in FIG. 10, the support pin 30 penetrating the support hole 3a serves as a fulcrum, and the support pin 30 penetrating the adjustment hole 3b is guided by the arcuate side of the adjustment hole 3b. It is possible to move, and thereby, the slanting member such as the support 301 can be adjusted to an arbitrary angle.

The connecting plate 3 is extended in this manner to extend the pillar 1.
When a vertical member such as 00 and a diagonal member such as a stirrup 301 are joined, the extended portion of the connecting plate 3 may protrude from the diagonal member and be exposed. In such a case, as shown in FIG. 8, the inside of the end of the extended portion of the coupling plate 3 (the pillar 1
(00 side) is cut diagonally, and in parallel with this,
It is preferable to provide a notch on the opposite edges. As a result, as shown in FIG. 10, the metal fittings are not exposed and the aesthetics of the building can be improved even when joining columns and braces having different joining angles, joints and braces, etc. As described above, according to the joining metal fitting of the present embodiment, it is possible to cope with a shaft of a wooden member of any size, orientation and angle.

The present invention is not limited to the above embodiments, but includes various modifications within the scope of the invention. For example, the seat plate 1 may have a rectangular shape, a polygonal shape, or the like, instead of the disk shape. By doing so, there is an effect that the seat plate 1 can be more firmly held by the seat holes 101 of the pillar 100.

[0044]

As described above, according to the joining metal fitting of the present invention, it is possible to join all kinds of wood members with only a metal fitting having a simple, small and lightweight structure, and the framing work is extremely easy and reliable. Moreover, the wooden members can be joined firmly and firmly.
