BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for a pillar, a pillar to be joined to the metal fitting, a wall structure using the metal fitting for the pillar, and a joining method thereof. The present invention relates to a column-joining metal fitting having improved strength, a pillar joined to the metal fitting, a wall structure using the pillar-jointing metal fitting, and a joining method thereof.

2. Description of the Related Art Wooden construction is an architectural style that has been practiced in Japan since ancient times, and even today, with skyscrapers and the like standing in the forest, it is actively built by taking advantage of the aesthetics or functions peculiar to wood.

The wooden building structure is not an integral structure like the RC structure, but is a structure in which structural members such as columns and beams are joined and assembled.

Therefore, in wooden construction, the strength of the wood itself is also important, but the strength of the joints that join the individual structural members is particularly important.

As such a joint, in Japan, there is a traditional joint type called a so-called Japanese-style joint.

The Japanese-style joint is a joint for joining structural members by fitting with a tenon or the like.

FIG. 18 shows a joining relationship for joining the pillar 1 and the base 2.

As can be seen in FIG. 18, the pillar 1 has a tenon 3,
The base 2 is provided with a mortise 4, and the pillar 1 and the base 2 are joined by fitting the mortise 3 and the mortise 4.

An important factor in designing the joint between the column and the base is how much the axial force of the column can be transmitted to the base in the design for long-term load.

Although the axial force of the column acts as a plunging force and acts on the foundation, the transverse compressive strength of wood is about one third of the longitudinal compressive strength, so it is important to secure the plunge area as much as possible. Becomes

Here, in the case of the joint portion as shown in FIG. 18, the tenon 3 does not contribute to the transmission of the axial force, so that it cannot be calculated as the recessed area.

Therefore, it is desirable to reduce the tenon 3 only from the viewpoint of securing the recessed area.

On the other hand, in designing for short-term loads such as earthquakes and winds, it is important how much horizontal shearing force or bending moment of a column can be transmitted to the foundation or how much pulling-out force of the column can be transmitted to the foundation. Become.

Since the horizontal shearing force is determined by the horizontal cross-sectional area of the tenon 3 in FIG. 18, the tenon 3 must be increased in order to increase the joint strength against the horizontal shearing force.

Therefore, when it is attempted to secure the recessed area, the mortise 3 and the mortise 4 are inevitably small,
There is a drawback that the resistance to horizontal shearing force becomes small.

On the other hand, recently, large-span wooden constructions have been built using large-section wooden members made of laminated wood or the like.

In addition, the revision of the Building Standards Law has made it possible to construct a three-story wooden house in a semi-fireproof area.

Along with such a tendency, both long-term load and short-term load for designing become large, and a joint portion having higher strength is required also in wooden construction.

FIG. 19 shows a joint portion in which a T-shaped reinforcing metal 7 is applied to the pillar 5 and the base 6 and the reinforcing metal 7 is fastened with bolts 8. The traditional Japanese-style joint Often used together with.

In FIG. 20, a reinforcing metal member 11 to which an anchor bolt 12 is welded is attached to a base 10, and a pillar 9 is fixed to the reinforcing metal member 11 with a bolt 13 to join the pillar 9 to the base 10. It shows the joint.

Other reinforcing metal parts include strip-shaped metal parts, battledore bolts, and glazing.

FIG. 21 shows a typical pillar, base and foundation. The RC foundation 14 and the base 15 are tightly connected by anchor bolts 16, and the pillar 17 is a traditional Japanese-style joint. At the same time, it is joined to the base 15 by a strip-shaped reinforcing metal member 18.

As described above, by using the reinforcing metal member, it is possible to improve the resistance force to the horizontal shearing force while ensuring the above-mentioned recessed area.

Further, a part of the pulling force generated in the pillar can be borne by the reinforcing metal member.

[0025]

Such high joint strength can be obtained by fastening the reinforcing metal object to the pillar and the base with nails, bolts, etc., but the nail to which the reinforcing metal object is attached is fixed. The bolt has the following problems.

First, when attaching a reinforcing metal fitting with a nail, it is necessary to drive a large number of nails in order to obtain a large joint strength. However, in order to prevent cracking of wood, a gap between the nails is required. A certain distance has to be ensured, which results in a considerable joint area.

Therefore, the joining strength is naturally limited.

Further, in the case of attaching the reinforcing metal object with the bolt, a through hole for passing the bolt is provided in the pillar or the base, and the bolt is inserted into the through hole to tightly connect the reinforcing metal object with the pillar or the base. Since there is a certain amount of play with respect to the bolt diameter, the joint strength can be expected, but the deformation of the joint may increase.

Not only the problems relating to the strength or deformation of the joints, but also the problem that the construction of the finishing material becomes difficult due to the protrusion of the bolt for attaching the metal for reinforcement, and the structural member has a large cross section. Along with this, the size of the metal for reinforcement also becomes large, which causes a problem of impairing the aesthetics of design.

The present invention has been made in consideration of the above-mentioned circumstances, and has a high joint strength in spite of the ease of construction, reduces the metal fitting portion exposed to the wooden structural member, and facilitates the construction of the finishing material. It is an object of the present invention to provide a metal fitting for joining a pillar, a pillar joined to the fitting, and a method for joining them.

[0039]

Embodiments of the present invention will be described below with reference to the accompanying drawings, embodiments of the metal fitting for pillars, the pillars to be joined to the metal fittings, the wall structure using the metal fittings for pillars, and the joining method thereof. .

In this embodiment, for the sake of convenience of description, the pillars are limited to through pillars and the like. However, the "pillar fitting metal fittings of the present invention, the pillars joined to the fittings and the wall using the pillar fitting fittings" The term "column" in the structure and the joining method for them is "through column, pipe column, stud, or any other column member that supports a vertical load. "Other structural members" means not only the base but also the girder, eaves girder,
In addition to including floor beams and other cross members, column members are also included, and "metal fittings" include metal fittings, reinforced plastics, ceramics, and the like.

FIG. 1 is a perspective view of the pillar-jointing metal fitting 21.

FIG. 2 is a side view of the pillar-jointing metal fitting 21.

The column joint fitting 21 includes a reference plate 22 applied to the column, a mounting plate 23 that stands upright from one end of the reference plate 22 and is mounted on another structural member (not shown), and the reference plate 22 and the mounting plate 23. Reinforcing plate 24 interposed to reinforce the
And are integrated.

Reference plate 22, mounting plate 23 and reinforcing plate 24
May be integrally formed by casting or the like, or the plates may be integrally assembled by welding.

The pillar joining fitting 21 is further provided with a rod-shaped positioning means 25 for positioning the mounting position of the pillar on the reference plate 22.

The alignment means 25 is preferably constructed by increasing the joint strength with the reinforcing plate 24 and / or the reference plate 22. In this embodiment, the rocket pin 26 is welded almost perpendicularly to the reference plate 22. Reinforcing plate 24
Also, it is fixed by welding, for example.

The length of the rocket pin 26 is preferably adjusted according to the requirement of the joint strength.

Further, the mounting plate 23 has a pillar-jointing metal member 21.
Is provided with a hole 28 through which a bolt for attaching to another structural member such as a base is inserted.

FIG. 3 shows a column 31 joined to the above-mentioned column joining fitting 21.

FIG. 4 (a) is a side view of the column 31, and FIG. 4 (b) is a vertical sectional view taken along the line AA of FIG. 4 (a). is there.

As can be seen from FIGS. 3 and 4, the pillar 31 is formed with a fitting portion 32a for fitting with the reinforcing plate 24 and a fitting portion 32b for fitting with the rod-shaped positioning means 25.

The inner diameter of the fitting portion 32b is the rocket pin 26.
It is recommended to keep the diameter approximately the same as or slightly smaller than the diameter of the torso.

The fitting portion 32b mounts the pillar 31 on the pillar-jointing metal fitting 21, and then the pillar 3 is mounted so that the axial force of the pillar 31 does not act on the rocket pin 26 but only on the mounting plate 23.
It is preferable that the height from the lower end of 1 to the center of the fitting portion 32b be slightly larger than the height from the upper end of the mounting plate 23 to the center of the rocket pin 26.

By doing this, in normal times,
The axial force of the column 31 acting vertically downward can be transmitted to the base or the like via the mounting plate 23, and the pulling force of the column 31 acting vertically upward can be transmitted to the base or the like via the rocket pin 26 during an earthquake. it can.

Since the fitting portions 32a and 32b can be precut at the factory, they can be finished with high precision.

Further, in order to prevent the reference plate 22 from protruding from the side surface of the column 31, the column 31 is provided with a second fitting portion 33.

In order to join the pillar 31 of this embodiment to another structural member such as the base using the pillar joining fitting 21 of this embodiment, first, as shown in FIG. 5, the pillar joining fitting 21 is attached. By advancing the plate 23 in the direction of the hatched arrow,
The anchor bolt 42 protruding from the base 41 is passed through the hole 28 provided in the mounting plate 23.

The anchor bolt 42 is previously fixed to a foundation 43 made of RC or the like.

Next, the attachment plate 23 is attached to the base 41 with the anchor bolt 42 and the nut 44.

If necessary, it is preferable to mount it by sandwiching a washer (not shown).

Next, the fitting portion 32a of the pillar 31 is attached to the reinforcing plate 24.
The column 31 is moved in the direction of the outline arrow while being fitted to.

Fitting portion 3 of pillar 31 into which reinforcing plate 24 is inserted
The inlet portion of 2a is preferably chamfered to facilitate insertion.

When the column 31 is further moved, the tip of the rocket pin 26 comes to a position where it is fitted in the inlet portion of the fitting portion 32b.

Here, since the rocket pin 26 has a sharp tip, the rocket pin 26 is smoothly inserted into the fitting portion 32b, and the entire pillar 31 can be easily positioned.

Here, as described above, the rocket pin 2
The diameter of the body portion of 6 is substantially the same as or slightly larger than the inner diameter of the fitting portion 32b, and the height from the lower end of the column 31 to the center of the fitting portion 32b is determined from the upper end of the mounting plate 23. Since the height of the rocket pin 26 is slightly larger than the center of the rocket pin 26, the body of the rocket pin 26 is fitted into the fitting part 32b after the tip of the rocket pin 26 is inserted into the fitting part 32b. In order to do so, the pillar 31 is moved from the side of the pillar 31 while applying force with a hammer, for example.

In this way, the rocket pin 26 is attached to the fitting portion 32.
The column 31 is joined to the column joint fitting 21 by press-fitting into the column b.
Can be firmly fixed to.

FIG. 6 shows a state in which the column 31 is moved until it comes into contact with the reference plate 22 of the metal fitting 21 for column joining.

Next, the pillar 31 and the reinforcing plate 24 are connected.

As described above, when the rocket pin 26 is completely press-fitted into the fitting portion 32b, the pillar 31 and the base 41 have already been firmly connected to each other via the pillar joining metal fitting 21.

However, a slight gap is provided between the reinforcing plate 24 and the fitting portion 32a for the convenience of construction.

In order to prevent the reduction of the bonding strength due to this gap, the gap between the two is filled with the adhesive 47 so that the column 31 and the reinforcing plate 24 are completely integrated.

The adhesive 47 is preferably selected from a material having a strength equal to or higher than that of wood and having good adhesion to wood and metal after curing.

For example, it is preferable to use an epoxy resin or the like.

FIG. 7 is a sectional view after the adhesive 47 is filled, and is shown at the same vertical sectional position as in FIG. 4 (b).

The column-joining metal fitting 2 of this embodiment described above
1. The pillars 31 joined to the metal fittings and the joining methods thereof provide the following advantages that cannot be achieved by the conventional technique.

The first advantage is that the construction of the pillar 31 becomes extremely easy.

That is, by constructing the positioning means 25 with the rocket pin 26, the pillar 31 can be easily positioned.

Therefore, no position adjustment or the like is required when the pillar 31 is attached to the pillar joint fitting 21, and the pillar 3
The construction accuracy of No. 1 can be improved and the construction period can be significantly shortened.

The second advantage is that the rocket pin 26 which is the positioning means 25 is fixed to the reinforcing plate 24 by welding or the like so as to increase the joint strength with the reinforcing plate 24, and the fitting portion 32b is formed. Since it is processed with high precision by pre-cutting, the rocket pin 26 is fixed to the pillar 31.
After being press-fitted into the fitting portion 32b, the mounting strength between the column 31 and the column-joining metal fitting 21 is significantly improved.

Therefore, the joint strength between the pillar 31 and the base 41 can be remarkably increased as compared with the prior art.

In other words, an axial force vertically downward acts on the pillar 31 due to a fixed load or a load, but this axial force acts on the base 41 via the mounting plate 23, so that the recessed area of the mounting plate 23 is reduced. It can take up area.

Therefore, there is almost no fear that the design axial force will be limited by the lateral compressive strength of the base 41.

In this case, since the gap between the fitting portion 32a and the reinforcing plate 24 is filled with the adhesive 47, it is not necessary to consider the cross-section loss.

Next, when a horizontal force due to an earthquake, wind, or the like acts on the structure, an upward pulling force acts on the pillar 31, as indicated by a white arrow in FIG.

This extraction force acts on the rocket pin 26, and the rocket pin 26 receives the force indicated by the thick arrow.

In this embodiment, since the rocket pin 26 is fixed to the reinforcing plate 24 by welding or the like, the above-mentioned force acting on the rocket pin 26 is transmitted to the base 41 via the reinforcing plate 24 and the mounting plate 23. Can be made.

Therefore, it is possible to prevent the pillar from coming off from the base due to the pulling-out force of the pillar that acts during an earthquake.

Further, the column 31 receives a horizontal shearing force at the time of an earthquake.

Of the horizontal shearing force, the horizontal shearing force in the direction orthogonal to the rocket pin 26 can be transmitted to the base 41 mainly through the reference plate 22.

The horizontal shearing force in the direction parallel to the rocket pin 26 also causes the frictional resistance between the rocket pin 26 and the fitting portion 32b and the reinforcing plate 24 and the fitting portion 32a by the adhesive 47.
It is possible to transmit it to the base 41 mainly through the reinforcing plate 24 due to the adhesive effect with.

Further, the column 31 receives a bending moment as shown by the white arrow in FIG. 9 during an earthquake.

On the tension side, this bending moment is resisted by one rocket pin 26 as indicated by the thick line arrow,
On the compression side, the pillar 31 as indicated by the hatched arrow
And the mounting plate 23 compresses and resists.

Therefore, by joining the pillar to the base using the metal fitting for joining the pillar according to the present embodiment, it is possible to secure a sufficient area to be embedded in the base, to have sufficient joint strength against horizontal force, and to pull it out. You can see that you can resist the force enough.

The third advantage is the ease of applying the finishing material.

That is, as can be seen from FIG. 6, on the wall surface side of the pillar 31 (direction along the base 41), there is no member protruding from the pillar 31 and the base 41.

Therefore, it becomes possible to directly attach the wall plate such as the inner wall or the outer wall to the pillar 31, and the construction of the inner and outer walls becomes very easy.

Further, if the inner wall or the outer wall is integrally constructed by using, for example, a plywood having a predetermined thickness, the rigidity in the vertical plane can be increased, so that it can be used as a seismic wall together with the improvement of the joint strength. While being able to
Depending on the design load, seismic resistant elements such as braces for increasing the rigidity in the vertical plane can be omitted.

The fourth advantage is that the amount of horizontal deformation is small.

That is, the rocket pin 26 is attached to the fitting portion 32.
Since the column 31 is press-fitted into b, the column 31 is firmly fixed to the base 41 via the column joining metal fitting 21.

Therefore, the amount of horizontal deformation of the column 31 at the time of an earthquake can be reduced.

In the joining method of this embodiment, the connecting step of connecting the column 31 and the reinforcing plate 24 was performed by the adhesive 47. However, as shown in FIG. 10, the bolt hole 51 is formed in the reinforcing plate 24a.
Prepare a column-jointing metal fitting 52 provided with
It is also possible to adopt a configuration in which the column 31 and the reinforcing plate 24a are coupled by coupling a coupling tool such as a screw or a bolt from the side of the column 31 via.

FIGS. 11 (a) and 11 (b) are side views of the column-joining metal fitting 52. As shown in FIG.

FIG. 12 is a perspective view showing a column 53 joined to the column joining fitting 52.

Unlike the column 31 described with reference to FIG. 3, the column 53 is further provided with a bolt hole 54 through which a coupling tool such as a bolt for connecting with the reinforcing plate 24a is inserted.

The procedure for joining the pillar 53 to the base 41 by using the pillar joining metal fitting 52 is almost the same as the procedure described in FIG. 5, but after the pillar 53 is brought into contact with the reference plate 22, the joining is performed. Tool, for example tapping screw 5 shown in FIGS. 13 and 14, respectively.
5a or a tapping screw 55b is inserted from the side of the pillar 53 and screwed into the pillar 53 on the other side of the reinforcing plate 24a while penetrating the bolt holes 51 and 54.

The tapping screw 55a is a stepped tapping screw as shown in FIG.
Reference numeral b is a stepping tapping screw as shown in FIG. 14, both of which can be screwed in with a hexagon wrench.

When the designed joining strength is large, the tapping screws 55a and 55b may be made slightly larger in outer diameter than the bolt holes 51, and the tapping screws 55a and 55b may be made larger.
Is firmly fixed in the bolt hole 51, and as a result, the pillar 5
3 and the reinforcing plate 24a can be integrated.

If necessary, the bolt holes 51, 54
Of course, it is only necessary to adjust the quantity of the adhesive, and when high joint strength is required, the adhesive 47 and the tapping screw 5
You may use together 5a and 55b.

In this embodiment, the reinforcing plate 24 and the reference plate 2 are used.
Positioning means 25 so that the bonding strength with 2 is increased.
The rocket pin 26 which is a reference plate 22 and the reinforcing plate 24
Although it is fixed to the reference plate 22 by welding or the like, the rocket pin 26 may be separated from the reinforcing plate 24 and fixed to the reference plate 22 if the joint strength is small in design.

Further, in this embodiment, the alignment means 25
Although it is composed of two rocket pins 26, the number of rocket pins 26 may be adjusted according to the designed joint strength.

Further, when a desired joining strength can be obtained by connecting the column and the reinforcing plate by using a tapping screw and / or an adhesive, the alignment means 2
The shape of 5 is not limited to the shape of a rocket pin, and may be, for example, a triangular pyramid-shaped projection.

In some cases, as shown in FIG. 15, the positioning means may be constituted by the reinforcing plate 24a, and the rocket pin 26 of this embodiment may be omitted to form the pillar-joining fitting 62.

FIG. 16 shows a pillar-jointing metal fitting 82 according to the second embodiment.

The column-joining metal fitting 82 is a horizontal brace 83,
Brace mounting means 85 and 86 for mounting the vertical brace 84 are provided on the mounting plate 23b and the reference plate 22b, respectively.

As described above, by increasing the joint strength by using the column joint fitting 21, seismic resistant elements such as braces can be omitted, but when the demand for the joint strength against horizontal force is very large, or When it is desired to reduce the size of the column joining metal fitting, it becomes necessary to provide a brace.

On the other hand, in many cases, the strength of the brace cannot exhibit the predetermined seismic performance because the strength of the joint between the brace, the pillar, and the base is less than that of the brace itself.

For example, when the brace is attached to the pillar, the pillar is lifted from the base due to the tensile force of the brace,
There may be situations where the brace cannot act as a horizontal force resisting member.

Such a problem is caused by the brace attaching means 8
The problem is solved by the column-joining metal fittings 82 provided with 5,86.

That is, the brace attaching means 85, 86
Since it is integrated as a part of the column-joining metal fitting 82, high brace joint strength can be obtained.

FIG. 17 shows a pillar-jointing fitting 92 according to the third embodiment.

The pillar-joining fitting 92 includes a reference plate 93 that is applied to the pillar and a reinforcing plate 94 that stands upright from the reference plate 93.
Are integrally provided, and a positioning means 91 for positioning the mounting positions of the columns is provided.

The alignment means 91 is constructed by increasing the joint strength between the reference plate 93 and the reinforcing plate 94.

That is, the alignment means 91 fixes two pairs of rocket pins 95a and 95b substantially perpendicular to the reference plate 93 on both sides of the reinforcing plate 94, and further fixes them to the reinforcing plate 94 by welding or the like. is there. The two pairs of rocket pins 95a and 95b are fixed to both the reference plate 93 and the reinforcing plate 94 to enhance the joint strength.

In order to join, for example, the pipe pillar on the second floor and the pipe pillar on the first floor by using the pillar-jointing metal fitting 92, the reinforcing plate 94 and the rocket pin are used in the same manner as the pillar-joining metal fitting 21 described in FIG. The fitting portion that fits with the 95a is provided at the lower end of the pipe pillar on the second floor, and the fitting portion that fits with the reinforcing plate 94 and the rocket pin 95b is provided at the upper end of the pipe pillar on the first floor.
95b may be press-fitted into the fitting portions of the pipe columns on the first floor and the pipe columns on the second floor, respectively.

Also in this case, as described above, by connecting the reinforcing plate and the tube column using the adhesive and / or the tapping screw, both tube columns can be joined with high joining strength.

[0126] The pillar-joining metal fittings, the pillars to be joined to the fittings, the wall structure using the pillar-jointing fittings, and their joining method according to the present embodiment are described in Japanese Patent Application No. Hei. The invention can also be applied to the metal fitting for joining a horizontal member disclosed in Japanese Patent No. 347476, a horizontal material joined to the metal fitting, and a joining method thereof.

[0127]

As described above, according to the pillar-joining metal fitting of the present invention, the pillar joined to the fitting, the wall structure using the pillar-jointing fitting, and the joining method thereof, the pillar can be easily formed. It can be installed and the joint strength can be significantly increased.

Moreover, since the exposed portion on the wooden structural member is reduced and the portion protruding from the side surface of the column is particularly eliminated, the inner and outer wall materials can be easily constructed.

Further, according to the metal fitting for pillars, the pillars to be joined to the metal fittings, the wall structure using the metal fittings for pillars, and their bonding method according to the present invention, the rod-shaped alignment means is used as the reference plate and 3. A pillar-jointing metal fixture fixed to at least one of the reinforcing plates, wherein the pillar-jointing metal fixture has a rod-shaped member as an alignment means fixed to at least one of the reference plate and the reinforcing plate. As described above, by using rocket pins as the alignment means, the structure can be simplified and the rod-shaped alignment means can be firmly fixed, and the use of a simple structure of the column joining metal fittings makes it extremely easy to construct columns. As a result, it is possible to improve the construction accuracy of the pillar, shorten the construction period, and significantly improve the mounting strength of the pillar and the pillar-jointing metal fitting.

An axial force vertically downward acts on the pillar due to a fixed load or a load, but this axial force is transmitted to other structural members (base, etc.) through the mounting plate, so that the embedded area is mounted. Although the area of the plate can be taken and a sufficient area can be obtained, even if horizontal force acts due to the action of an earthquake or wind, these forces are applied to the reference plate or the rocking pin through the rod-shaped alignment means or rocket pin. Since it is transmitted to the reinforcing plate and is transmitted from the mounting plate to other structural members (base etc.), it is possible to effectively prevent the column from coming off due to the pulling force of the column that acts during an earthquake.
