2. Description of the Related Art Wooden construction is an architectural style that has been practiced in Japan since ancient times, and even in the modern day when skyscrapers and the like are forested, it is actively built by taking advantage of the unique aesthetics and functions of wood.

The wooden building structure is not an integral structure such as an 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.

[0007] Fig. 24 shows a joint relationship for joining a column and a beam. Fig. 24 (a) shows a joint portion in which a floor beam 3 is joined to a tube column 1a and a barrel 2. b) is through column 1
The joint part which joined the floor beam 3 to b is shown.

In both cases of the pipe column 1a and the through column 1b, the shearing force of the floor beam 3 is controlled by placing a notch such as a large insert in the column and placing the end of the floor beam 3 in the notch. It is adapted to be transmitted to the pillar 1a or the through pillar 1b.

Further, in FIG. 24, in order to prevent the floor beam 3 from coming off from the tube column 1a or the through column 1b, the tube column 1a or the through column 1b and the floor beam 3 are tightly connected with the battledore bolts 4.

That is, the joint portion of FIG. 24 is a joint portion in which a traditional Japanese-style joint and a battledore bolt 4 as a metal for reinforcement are used together. A lot of hardware is used.

In Europe and the United States, there are many types of joining only by a metal fitting for reinforcement, rather than joining by fitting as in Japan.

FIGS. 25A and 25B show the beam 5 and the pillar 6.
Apply the T-shaped reinforcing hardware 7 to the
3 shows a joint portion in which is fastened with a bolt 8.

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

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

For this reason, even in wooden construction, a joint portion having higher strength is required.

Such a high joint strength can be obtained by fastening the reinforcing metal object to the pillar and the beam with nails, bolts or the like. There is a problem.

First, when attaching a reinforcing metal member 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 must be ensured and, as a result, a considerable joint area is required.

Therefore, the joining strength is naturally limited.

In addition, when the reinforcing metal fitting is attached by the bolt, a through hole for passing the bolt is provided in the pillar or the beam,
A bolt is inserted into this through hole to tightly connect the reinforcing metal and the pillar or beam. Since the through hole has a certain amount of play with respect to the bolt diameter, the joint strength can be expected, but the deformation of the joint becomes large. It may happen.

Not only the problem of the strength or deformation of the joint, 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 increase of the cross section of the structural member. Along with this, the size of the reinforcing metal also becomes large, which causes a problem of impairing the aesthetics of the design.

Japanese Utility Model Laid-Open No. 2-74403 discloses a fastening member for a column and a horizontal member, which has a higher joint strength.

FIG. 26 shows a procedure for joining the horizontal member 10 to the column 19 by using the above-mentioned fastener 11.

In order to join the pillar 9 and the horizontal member 10 with the fastener 11, the fastener 11 is first fixed to the pillar 9 with the bolts 12 and the nuts 18 in advance, and the fastener 11 is laterally moved from above. The frame material 10 is lowered and lowered.

Here, the horizontal member 10 is provided with a notch 14, and the horizontal member 10 is lowered while fitting the protrusion 13 provided on the fastener 11 into the notch 14.

FIG. 27 (a) shows a state in which the horizontal member 10 is completely lowered.

Next, as shown in FIG. 27 (b), the horizontal member 10 is brought close to the pillar 9 by driving a wedge 15 into the remaining portion of the notch 14.

Finally, as shown in FIG. 27 (c), the upper fixing plate 16 is attached with bolts 17 to complete the joining.

[0028]

However, as shown in FIG.
As can be seen from (c), since the upper fixing plate 16 and the bolt 17 are present, the upper end of the horizontal member 10 is not flat.

Therefore, when the floor boards are directly applied to the floor beams 10 without the joists, the floor boards are difficult to apply.

When the horizontal member 10 is lowered and lowered along the pillar 9, the nut 18 shown in FIG.
As shown in (a), the horizontal member 10 is once released to the side by the height of the nut 18, and the horizontal member 10 is brought into contact with the bottom plate of the fastener 11, and then the horizontal member 10 is removed. To the pillar 9,
The nut 18 is adapted to fit into a fitting portion 19 shown in FIG.

For this reason, the horizontal member 10 cannot be lowered straight after the pillar 9 is fixed upright. Therefore,
The column 9 is temporarily fixed so that the column 9 can be moved slightly to the side, the horizontal member 10 is completely lowered, the wedge 15 is driven, and the column 9 is brought closer to the column 9, and then the column 9 is completely fixed.

Therefore, when joining the second and third floor beams to the through columns of the three-story house using the fasteners 11,
Construction becomes considerably difficult.

Further, since the horizontal member 10 and the fastening member 11 are not tightly connected in the horizontal direction, the horizontal member 10 and the fastening member 11 cannot be regarded as one body, and therefore the above-mentioned notch 14 is A large cross section is lost.

Therefore, when a horizontal force such as an earthquake or wind is applied in the direction indicated by the white arrow in FIG.
In calculating the horizontal shearing force that can be transmitted to the column 9 via ₁ , only the cross section corresponding to the width d ₁ can be considered, not the entire cross section of the horizontal member 10.

Therefore, if the horizontal cross member 10 is designed so that its entire cross section is effective, the shear stress is concentrated on the portion having the width d ₁ and the horizontal cross member 10 may be sheared and broken at the corner of the notch 14. is there.

Further, as described above, the fastener 11 is provided with a large rectangular notch 14 for fitting the ridge 13 and the wedge 15 in the horizontal member 10, and such a square hole is Processing is relatively complicated compared to round holes.

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

[0038]

In order to achieve the above object, the metal fitting for joining a horizontal member of the present invention has a reference plate for receiving a horizontal member and one side of the reference plate as described in claim 1. Position where the mounting plate that stands upright from the end and is mounted on another structural member and the reinforcing plate that is interposed so as to reinforce the reference plate and the mounting plate are integrally provided, and the mounting position of the horizontal member is aligned. The mating portion is provided on the reference plate.

As described in claim 6, the horizontal member of the present invention includes a reference plate for receiving the horizontal member, a mounting plate which stands upright from one side end of the reference plate and is attached to another structural member, and the reference plate. Plate and a reinforcing plate interposed so as to reinforce the mounting plate are integrally provided, and a positioning member for positioning the mounting position of the horizontal member is provided on the reference plate. A fitting portion that fits the reinforcing plate and the alignment portion is formed.

Further, as described in claim 8, the horizontal member of the present invention includes a reference plate for receiving the horizontal member, a mounting plate which stands upright from one end of the reference plate and is attached to another structural member, and the reference plate. A plate and a reinforcing plate which is interposed so as to reinforce the mounting plate are formed integrally with each other to form a fitting portion that fits with the reinforcing plate of a horizontal frame joining metal fitting, and the mounting plate is not The fitting groove is provided at a position corresponding to the position of the attachment member for attachment to the structural member.

Further, according to the joining method of the present invention, as described in claim 9, in the joining method of joining the horizontal member to another structural member, the mounting plate of the horizontal member joining metal fitting is attached to the other structural member. Attaching process, and fitting the horizontal bridge material to the vertical groove provided in the horizontal bridge while fitting the reinforcing plate and the alignment part of the horizontal bridge to the fitting provided on the horizontal bridge. A fitting step of lowering and lowering the horizontal member while fitting the mounting member of, and after the horizontal member comes into contact with the reference plate,

[0042]

With the above-described metal fitting for joining a horizontal member, the horizontal material to be joined to the metal fitting, and the joining method thereof, the horizontal material can be easily constructed and the joining strength can be increased.

Moreover, since the exposed portion on the wooden structural member is reduced and the portion protruding from the upper surface of the beam is particularly eliminated, it is possible to easily construct a floorboard, for example.

[0044]

FIG. 1 is a perspective view showing the metal fitting 21 for joining the horizontal members.

Further, FIG. 2A is a side view of the metal fitting 21 for joining the horizontal members, and FIG. 2B is a plan view thereof.

The horizontal member joining metal fitting 21 includes a reference plate 22 for receiving a horizontal member (not shown), and a mounting plate 23 that stands upright from one end of the reference plate 22 and is attached to another structural member (not shown).
And a reinforcing plate 24 interposed so as to reinforce the reference plate 22 and the mounting plate 23 are integrally provided.

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

Further, the metal fitting 21 for joining the horizontal members of this embodiment
Is provided with a second alignment portion 27 for aligning the horizontal material joining metal fitting 21 itself to a predetermined position of the column, and the mounting material 23 is attached to the column with the horizontal material joining metal fitting 21. A hole 28 for passing a bolt is provided.

FIG. 3 shows a horizontal member 31 to be joined to the above-mentioned metal member 21 for joining a horizontal member.

Further, FIG. 4 (a) is a side view of the horizontal member 31, and FIG. 4 (b) is a horizontal sectional view taken along the line AA of FIG. 4 (a). It is a thing.

As can be seen in FIGS. 3 and 4, the horizontal member 31
Has a fitting portion 32a that fits with the reinforcing plate 24 and a fitting portion 32b that fits with the alignment portion 25.

The inner diameter of the fitting portion 32b is the rocket pin 26.
It is better to keep the diameter of the body part of the same as or slightly smaller.

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 projecting from the lower surface of the horizontal member 31, a second fitting portion 33 may be provided on the horizontal member 31.

Further, the horizontal member 31 is preferably provided with a fitting groove 34 at a position corresponding to the position of a mounting member such as a bolt for mounting the mounting plate 23 on a pillar.

To join the horizontal member 31 of this embodiment to another structural member, for example, a pillar, using the metal fitting 21 for connecting the horizontal member of this embodiment, first, as shown in FIG. Metal fittings for joining 2
The mounting plate 23 of No. 1 is advanced in the direction of the hatched arrow, and is fitted into the fitting mounting portion 42 provided on the pillar 41.

Since the fitting portion 43 is provided with the fitting portion 43 which fits with the second alignment portion 27 provided on the metal fitting 21 for connecting the horizontal material, the metal fitting 21 for connecting the horizontal material is supported by the pillar. It can be positioned exactly at 41.

Next, the mounting plate 23 of the fitting 21 for joining the horizontal members
To the post 41 with bolts 44 and nuts 45.

If necessary, the washer 46 may be sandwiched and attached.

FIG. 6 shows the metal fitting 21 for joining the horizontal members which has been attached to the pillar 41.

Referring again to FIG. 5, the fitting portion 32a of the horizontal member 31 is fitted to the reinforcing plate 24 and lowered in the direction of the white arrow in FIG.

The lower portion of the fitting portion 32a of the horizontal member 31 into which the reinforcing plate 24 is inserted is preferably chamfered to facilitate insertion.

As shown in FIG. 6, the metal fitting 21 for joining the horizontal members is attached to the pillar 4
When the bolt 45 protrudes from the surface of the column 41 in the state where the bolt 45 is attached to the column 1, the horizontal groove 31 is provided with a fitting groove 34 corresponding to the position of the bolt 45. The horizontal member 31 and the bolt 45 can be prevented from hitting by lowering and lowering the horizontal member 31 while fitting.

Referring to FIG. 5 again, when the horizontal member 31 is further lowered, the tip portion of the rocket pin 26 is moved to the fitting portion 3
It comes to the position where it fits with the lower part of 2b.

Since the tip of the rocket pin 26 is sharpened, the rocket pin 26 can be smoothly inserted into the fitting portion 32b, and the entire horizontal member 31 can be easily positioned.

Since the diameter of the body portion of the rocket pin 26 is substantially the same as or slightly larger than the inner diameter of the fitting portion 32b, the tip of the rocket pin 26 is inserted into the fitting portion 32b. After that, in order to fit the body portion of the rocket pin 26 into the fitting portion 32b, the horizontal member 31 is lowered from above the horizontal member 31 while applying force with a hammer, for example.

In this way, the rocket pin 26 is attached to the fitting portion 32.
By press-fitting into b, the horizontal member 31 can be firmly fixed to the horizontal member joining fitting 21.

In FIG. 7, the horizontal member 31 is a metal member 2 for connecting the horizontal member.
1 shows a state in which the horizontal member 31 is lowered and lowered until it comes into contact with the reference plate 22 of No. 1.

Next, the horizontal member 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 horizontal member 31 has already been pressed.
The columns 41 are firmly connected to each other via the horizontal member joining metal fitting 21.

However, a small 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 47 is filled with the adhesive 47 so that the horizontal member 31 and the reinforcing plate 24 are completely integrated.

The adhesive 47 is preferably selected from a material having 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. 8 is a cross-sectional view after the adhesive 47 is filled, which is shown in the same horizontal position as in FIG. 4 (b).

FIG. 9 shows one pillar 41 with four horizontal members 3
1A, 31b, 31c, and 31d are joined together in a plan view, and FIG. 10 is a perspective view showing a crossing state of bolt holes 48 formed in a pillar 41.

The above-described metal fitting 21 for joining the horizontal members, the horizontal material 31 to be joined to the metal fitting, and the joining method thereof according to the present embodiment have the following advantages that cannot be achieved by the prior art.

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

That is, by constructing the positioning section 25 with the rocket pin 26, the horizontal member 31 can be easily positioned.

Therefore, no position adjustment or the like is required when the horizontal member 31 is attached to the horizontal member joining metal fitting 21, so that the construction accuracy of the horizontal member 31 can be improved and the construction period can be greatly shortened. be able to.

Further, even if the member for mounting on the pillar 41 is projected from the pillar surface, the provision of the fitting groove 34 eliminates the need to lower the horizontal member 31 after allowing the pillar 41 to escape to the side. The construction procedure can be omitted, and it is particularly advantageous when using through columns in a three-story house or the like.

A second advantage is that the rocket pin 26, which is the alignment portion 25, is fixed to the reinforcing plate 24 by welding or the like so as to also serve as joint reinforcement, and the fitting portion 32b is pre-cut with high precision. Since the rocket pins 26 are processed, the rocket pins 26 are fitted to the fitting portions 32 of the horizontal members 31.
After press-fitting into b, the horizontal member 31 and the horizontal member joining metal fitting 21
That is, the mounting strength with and is significantly improved.

Therefore, the joint strength between the horizontal member 31 and the column 41 can be remarkably increased as compared with the prior art.

That is, a vertical shearing force and a bending moment about the horizontal axis act on the horizontal member 31 due to a vertical force such as a fixed load or a load applied to the horizontal member 31, but the reference plate 22, Plate 23 and reinforcing plate 24
The shear force can be sufficiently transmitted to the column 41 by integrally configuring the.

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 defect of the cross section at all.

Further, the rocket pin 26 and the fitting portion 32
By configuring b as described above, the bending moment about the horizontal axis is applied to the pillar 41 via the metal fitting 21 for joining the horizontal members.
Can be fully communicated.

Here, the adhesive force in the shearing direction between the reinforcing plate 24 and the horizontal member 31 and the adhesive 47 can contribute to the above-mentioned bending moment resistance force.

It is possible to prevent the horizontal member 31 from slipping upward at the same time due to the shear resistance of the adhesive 47 and the shear resistance between the rocket pin 26 and the fitting portion 32b.

When a horizontal force in the pulling direction is applied to the cross member 31 in the pulling direction, the rocket pin 26 mainly resists, and the shear resistance of the adhesive 47 also contributes to this.

The tensile force received by the rocket pin 26 is transmitted to the column 41 via the reinforcing plate 24.

Next, as shown in FIG. 11, when a horizontal force due to an earthquake or wind acts on the horizontal member 31 (acting in the direction of the white arrow in FIG. 11), the horizontal member 31 Is subject to horizontal shear forces and bending moments around the vertical axis.

In this embodiment, the rocket pin 26 is press-fitted into the fitting portion 32b, and the adhesive 47 is filled in the gap between the fitting portion 32a and the reinforcing plate 24, so that the horizontal member 31
Since the reinforcing plate 24 and the reinforcing plate 24 are integrated in the horizontal direction,
The horizontal shearing force of the horizontal member 31 is transmitted to the column 41 without causing stress concentration at a specific place.

Further, the bending moment about the vertical axis due to the horizontal force is transmitted as a compressive force from the horizontal member 31 to the column 41 on the compression side (hatched arrow in FIG. 11), and is mainly pulled to the rocket pin 26 on the tension side. Acting as a force, the rocket pin 26 transmits this tensile force to the column via the reinforcing plate 24.

Therefore, it is possible to have sufficient joint strength not only for vertical force but also for horizontal force by joining using the metal member for joining the horizontal members and the horizontal member according to this embodiment. Recognize.

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

That is, as can be seen in FIG.
There is no member protruding from the upper surface of.

Therefore, when the floorboard is directly installed on the horizontal member 31 without the joists, the floorboard can be easily installed.

Further, if the floorboard is integrally constructed by using, for example, a plywood of about 28 mm, the rigidity in the horizontal plane can be increased, and in addition to the above-mentioned improvement in the joint strength, the seismic resistance can be further increased. Depending on the design load, it is possible to omit seismic elements such as braces and striking beams for increasing the rigidity in the horizontal plane.

The fourth advantage is that since the horizontal fitting material joining metal fitting 21 has only the reference plate 22 exposed to the horizontal installation material 31 or the pillar 41, the area is the same as that of the reference plate 22 and the horizontal installation material 31. If a decorative plate having an equivalent appearance is attached to the outer surface of the reference plate 22 to make the lower surface of the horizontal member 31 uniform, it is possible to make the horizontal member joining metal fitting 21 completely invisible. ..

Therefore, it is very advantageous in designing the beauty of the wood itself.

In the joining method of this embodiment, the connecting step for connecting the horizontal member 31 and the reinforcing plate 24 was performed with the adhesive 47. However, as shown in FIG. 12, the bolt holes 51 are provided in the reinforcing plate 24a. A horizontal fitting member 52 is prepared, and a screw or a bolt is screwed from the side of the horizontal member 31 through the bolt hole 51 to connect the horizontal member and the reinforcing plate 24a. Good.

FIGS. 13 (a) and 13 (b) show the metal member 5 for joining the horizontal members.
2 is a side view and a plan view, respectively.

FIG. 14 is a perspective view showing the horizontal member 53 to be joined to the horizontal member fitting 52.

Unlike the horizontal member 31 described with reference to FIG. 3, the horizontal member 53 is further provided with a bolt hole 54 through which a bolt for connecting to the reinforcing plate 24a is inserted.

The procedure for joining the horizontal member 53 to the pillar 41 by using the horizontal member joining metal fitting 52 is almost the same as the procedure described in FIG. 5, but as shown in FIG. After abutting 53 on the reference plate 22, tapping screws 55a, 55b respectively shown in FIGS. 16 and 17 are inserted from the lateral side of the horizontal member 53, and the bolt holes 51 and 54 are penetrated to reinforce the reinforcing plate 24a. The difference is that it is screwed into the horizontal member 53 on the other side.

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. 17, 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 formed.
Is firmly fixed to the bolt hole 51, and as a result, the horizontal member 53 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 bonding strength is required, the adhesive 47 and the tapping screw 5
You may use together 5a and 55b.

In FIG. 18, the metal member 52 for joining the horizontal members is attached to the pillar 41.
19 is a view showing a state in which the horizontal member 53 is joined to the column 41, and FIG.

Further, in this embodiment, the rocket pin 26, which is the alignment portion 25, is fixed to the reference plate 22 and the reinforcing plate 24 by welding or the like so as to also serve as joint reinforcement. If the strength may be small, the rocket pin 26 may be separated from the reinforcing plate 24 and fixed on the reference plate 22 as shown in FIG. 20, or as shown in FIG. It may be the mating portion 25a.

Further, in the present embodiment, the position aligning section 25 is composed of two rocket pins 26, but the number of rocket pins 26 may be adjusted according to the design bonding strength.

Further, the shape of the alignment portion 25 is not limited to the rocket pin, and for example, by fixing the stiffening rib to the reinforcing plate 24 and the reference plate 22 so as to be orthogonal to them, the joint reinforcement can be achieved. The positioning section may also serve as the double-sided positioning section, or may be simply the positioning section.

Further, in this embodiment, the metal fitting 2 for joining the horizontal members is used.
Although the second alignment portion 27 is provided in the position 1, the horizontal fitting member 21 itself can be easily aligned, but in some cases, the second alignment portion 27 is used.
May be omitted.

As a modified example of the horizontal material joining metal fitting 21 of this embodiment, a horizontal material joining metal fitting 61,
62 is shown.

The metal fittings 61, 62 for joining the horizontal members are provided with brace attachment portions 65, 66 for attaching the horizontal brace 63 and the vertical brace 64, respectively, to the reference plate 22b and the reinforcing plate 2.
It is provided in 4b.

Further, as described above, by increasing the joint strength by using the metal fittings 21 for joining the horizontal members, seismic resistant elements such as fire beams and braces can be omitted, but the joint strength against horizontal force is required. If it is very large, or if it is desired to reduce the size of the metal fitting for joining the horizontal members, it becomes necessary to provide a brace.

On the other hand, with respect to the strength of the brace, the joint strength between the brace and the pillar or the beam is insufficient as compared with the strength of the brace itself, so that a predetermined seismic resistance cannot be exhibited in many cases.

Such a problem is caused by the brace attaching portion 6
The problem is solved by providing 5, 66 to the metal fittings 61, 62 for joining the horizontal members.

That is, the brace mounting portions 65, 66
Since it is integrated as a part of the metal fittings 61, 62 for joining the horizontal members, a high brace joining strength can be obtained.

Note that FIG. 22 assumes the case where the horizontal member is a floor beam, and FIG. 23 assumes the case where the horizontal member is a barrel.

Although the horizontal member of the present invention has been described as being used for the horizontal member joining metal fitting of this embodiment, the reference plate for receiving the horizontal member and the upright from one side end of the reference plate. It can also be widely used for a horizontal member joining metal fitting integrally provided with a mounting plate to be mounted on another structural member and a reference plate and a reinforcing plate interposed so as to reinforce the mounting plate.

That is, in the horizontal member of the present invention, a fitting portion for fitting with the reinforcing plate is formed, and a position corresponding to the position of the mounting member for mounting the mounting plate to the other structural member. Since the fitting groove is provided in the side wall, it is not necessary to allow the pillar to escape to the side, and in a wooden structure with three or more floors, it is extremely easy to construct a horizontal member.

[0128]

As described above, according to the metal fitting for joining a horizontal member, the horizontal material to be joined to the metal fitting and the joining method thereof, the horizontal material can be easily constructed. At the same time, the bonding strength can be increased.

Moreover, since the exposed portion of the wooden structural member is reduced, and in particular, the portion protruding from the upper surface of the beam is eliminated, it is possible to easily construct a floorboard, for example.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for joining a horizontal material, a horizontal material to be joined to the metal fitting, and a joining method thereof, and particularly to a horizontal material which is easy to construct and has an improved bonding strength. TECHNICAL FIELD The present invention relates to a metal fitting for joining, a horizontal member to be joined to the metal fitting, and a joining method thereof.

[0002]

2. Description of the Related Art Wooden construction is an architectural style that has been practiced in Japan since ancient times, and even in the modern day when skyscrapers and the like are forested, it is actively built by taking advantage of the unique aesthetics and functions of wood.

The wooden building structure is not an integral structure such as an 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.

[0007] Fig. 24 shows a joint relationship for joining a column and a beam. Fig. 24 (a) shows a joint portion in which a floor beam 3 is joined to a tube column 1a and a barrel 2. b) is through column 1
The joint part which joined the floor beam 3 to b is shown.

In both cases of the pipe column 1a and the through column 1b, the shearing force of the floor beam 3 is controlled by placing a notch such as a large insert in the column and placing the end of the floor beam 3 in the notch. It is adapted to be transmitted to the pillar 1a or the through pillar 1b.

Further, in FIG. 24, in order to prevent the floor beam 3 from coming off from the tube column 1a or the through column 1b, the tube column 1a or the through column 1b and the floor beam 3 are tightly connected with the battledore bolts 4.

That is, the joint portion of FIG. 24 is a joint portion in which a traditional Japanese-style joint and a battledore bolt 4 as a metal for reinforcement are used together. A lot of hardware is used.

In Europe and the United States, there are many types of joining only by a metal fitting for reinforcement, rather than joining by fitting as in Japan.

FIGS. 25A and 25B show the beam 5 and the pillar 6.
Apply the T-shaped reinforcing hardware 7 to the
3 shows a joint portion in which is fastened with a bolt 8.

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

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

For this reason, even in wooden construction, a joint portion having higher strength is required.

Such a high joint strength can be obtained by fastening the reinforcing metal object to the pillar and the beam with nails, bolts or the like. There is a problem.

First, when attaching a reinforcing metal member 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 must be ensured and, as a result, a considerable joint area is required.

Therefore, the joining strength is naturally limited.

In addition, when the reinforcing metal fitting is attached by the bolt, a through hole for passing the bolt is provided in the pillar or the beam,
A bolt is inserted into this through hole to tightly connect the reinforcing metal and the pillar or beam. Since the through hole has a certain amount of play with respect to the bolt diameter, the joint strength can be expected, but the deformation of the joint becomes large. It may happen.

Not only the problem of the strength or deformation of the joint, 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 increase of the cross section of the structural member. Along with this, the size of the reinforcing metal also becomes large, which causes a problem of impairing the aesthetics of the design.

Japanese Utility Model Laid-Open No. 2-74403 discloses a fastening member for a column and a horizontal member, which has a higher joint strength.

FIG. 26 shows a procedure for joining the horizontal member 10 to the column 19 by using the above-mentioned fastener 11.

In order to join the pillar 9 and the horizontal member 10 with the fastener 11, the fastener 11 is first fixed to the pillar 9 with the bolts 12 and the nuts 18 in advance, and the fastener 11 is laterally moved from above. The frame material 10 is lowered and lowered.

Here, the horizontal member 10 is provided with a notch 14, and the horizontal member 10 is lowered while fitting the protrusion 13 provided on the fastener 11 into the notch 14.

FIG. 27 (a) shows a state in which the horizontal member 10 is completely lowered.

Next, as shown in FIG. 27 (b), the horizontal member 10 is brought close to the pillar 9 by driving a wedge 15 into the remaining portion of the notch 14.

Finally, as shown in FIG. 27 (c), the upper fixing plate 16 is attached with bolts 17 to complete the joining.

[0028]

However, as shown in FIG.
As can be seen from (c), since the upper fixing plate 16 and the bolt 17 are present, the upper end of the horizontal member 10 is not flat.

Therefore, when the floor boards are directly applied to the floor beams 10 without the joists, the floor boards are difficult to apply.

When the horizontal member 10 is lowered and lowered along the pillar 9, the nut 18 shown in FIG.
As shown in (a), the horizontal member 10 is once released to the side by the height of the nut 18, and the horizontal member 10 is brought into contact with the bottom plate of the fastener 11, and then the horizontal member 10 is removed. To the pillar 9,
The nut 18 is adapted to fit into a fitting portion 19 shown in FIG.

For this reason, the horizontal member 10 cannot be lowered straight after the pillar 9 is fixed upright. Therefore,
The column 9 is temporarily fixed so that the column 9 can be moved slightly to the side, the horizontal member 10 is completely lowered, the wedge 15 is driven, and the column 9 is brought closer to the column 9, and then the column 9 is completely fixed.

Therefore, when joining the second and third floor beams to the through columns of the three-story house using the fasteners 11,
Construction becomes considerably difficult.

Further, since the horizontal member 10 and the fastening member 11 are not tightly connected in the horizontal direction, the horizontal member 10 and the fastening member 11 cannot be regarded as one body, and therefore the above-mentioned notch 14 is A large cross section is lost.

Therefore, when a horizontal force such as an earthquake or wind is applied in the direction indicated by the white arrow in FIG.
In calculating the horizontal shearing force that can be transmitted to the column 9 via ₁ , only the cross section corresponding to the width d ₁ can be considered, not the entire cross section of the horizontal member 10.

Therefore, if the horizontal cross member 10 is designed so that its entire cross section is effective, the shear stress is concentrated on the portion having the width d ₁ and the horizontal cross member 10 may be sheared and broken at the corner of the notch 14. is there.

Further, as described above, the fastener 11 is provided with a large rectangular notch 14 for fitting the ridge 13 and the wedge 15 in the horizontal member 10, and such a square hole is Processing is relatively complicated compared to round holes.

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

[0043]

With the above-described metal fitting for joining a horizontal member, the horizontal material to be joined to the metal fitting, and the joining method thereof, the horizontal material can be easily constructed and the joining strength can be increased.

Moreover, since the exposed portion on the wooden structural member is reduced, and in particular, the portion protruding from the upper surface of the beam is eliminated, it is possible to easily construct a floorboard, for example.

[0045]

Embodiments of the present invention will now be described with reference to the accompanying drawings with reference to the accompanying drawings, which is a fitting for joining a horizontal material, a horizontal material to be joined to the fitting, and a joining method thereof.

In the present embodiment, for convenience of explanation, the horizontal member is limited to the barrel or floor beam, but the metal member for connecting the horizontal member of the present invention and the horizontal member to be joined to the metal member are connected. The term "horizontal material" in "Materials and their joining methods" refers to all horizontal materials that are subjected to vertical loads, such as girders, eaves girders, floor beams, shed beams, joists, foundations, etc. "Metal fittings" refers to fittings for joining these horizontal members to other structural members.

The foundation and other horizontal materials are also included.

FIG. 1 is a perspective view showing a metal fitting 21 for joining a horizontal member.

Further, FIG. 2A is a side view of the metal fitting 21 for joining the horizontal members, and FIG. 2B is a plan view thereof.

The horizontal member joining metal fitting 21 includes a reference plate 22 for receiving a horizontal member (not shown), and a mounting plate 23 which stands upright from one end of the reference plate 22 and is attached to another structural member (not shown).
And a reinforcing plate 24 interposed so as to reinforce the reference plate 22 and the mounting plate 23 are integrally provided.

6 is fixed to the reference plate 22 almost vertically, and further fixed to the reinforcing plate 24 by, for example, welding.

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

Further, the metal fitting 21 for joining the horizontal members of this embodiment
Is provided with a second alignment portion 27 for aligning the horizontal material joining metal fitting 21 itself to a predetermined position of the column, and the mounting material 23 is attached to the column with the horizontal material joining metal fitting 21. A hole 28 for passing a bolt is provided.

FIG. 3 shows a horizontal member 31 to be joined to the above-mentioned metal member 21 for connecting a horizontal member.

FIG. 4 (a) is a side view of the horizontal member 31, and FIG. 4 (b) is a horizontal sectional view taken along the line AA of FIG. 4 (a). It is a thing.

As shown in FIGS. 3 and 4, the horizontal member 31
Has a fitting portion 32a that fits with the reinforcing plate 24 and a fitting portion 32b that fits with the alignment portion 25.

The inner diameter of the fitting portion 32b is the rocket pin 26.
It is better to keep the diameter of the body part of the same as or slightly smaller.

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 projecting from the lower surface of the horizontal member 31, a second fitting portion 33 may be provided on the horizontal member 31.

The horizontal member 31 is preferably provided with a fitting groove 34 at a position corresponding to the position of a mounting member such as a bolt for mounting the mounting plate 23 on a pillar.

To join the horizontal member 31 of this embodiment to another structural member, such as a column, using the metal fitting 21 for connecting the horizontal member of this embodiment, first, as shown in FIG. Metal fittings for joining 2
The mounting plate 23 of No. 1 is advanced in the direction of the hatched arrow, and is fitted into the fitting mounting portion 42 provided on the pillar 41.

Since the fitting portion 43 is provided with the fitting portion 43 that fits with the second alignment portion 27 provided on the metal fitting 21 for connecting the horizontal material, the metal fitting 21 for connecting the horizontal material is supported by the pillar. It can be positioned exactly at 41.

Next, the mounting plate 23 of the fitting 21 for joining the horizontal members
To the post 41 with bolts 44 and nuts 45.

If necessary, the washer 46 may be sandwiched and attached.

FIG. 6 shows the metal fitting 21 for joining the horizontal member which is completely attached to the pillar 41.

Referring again to FIG. 5, the fitting portion 32a of the horizontal member 31 is fitted to the reinforcing plate 24 and lowered in the direction of the white arrow in FIG.

The lower portion of the fitting portion 32a of the horizontal member 31 into which the reinforcing plate 24 is inserted is preferably chamfered to facilitate insertion.

As shown in FIG. 6, the metal member 21 for joining the horizontal members is attached to the pillar 4
When the bolt 45 protrudes from the surface of the column 41 in the state where the bolt 45 is attached to the column 1, the horizontal groove 31 is provided with a fitting groove 34 corresponding to the position of the bolt 45. The horizontal member 31 and the bolt 45 can be prevented from hitting by lowering and lowering the horizontal member 31 while fitting.

Referring again to FIG. 5, when the horizontal member 31 is further lowered, the tip of the rocket pin 26 is moved to the fitting portion 3
It comes to the position where it fits with the lower part of 2b.

Since the tip of the rocket pin 26 is sharpened, the rocket pin 26 can be smoothly inserted into the fitting portion 32b and the horizontal member 31 can be positioned easily.

Since the diameter of the body portion of the rocket pin 26 is substantially the same as or slightly larger than the inner diameter of the fitting portion 32b, the tip of the rocket pin 26 is inserted into the fitting portion 32b. After that, in order to fit the body portion of the rocket pin 26 into the fitting portion 32b, the horizontal member 31 is lowered and lowered while applying force from above the horizontal member 31, for example, with a hammer.

In this way, the rocket pin 26 is attached to the fitting portion 32.
By press-fitting into b, the horizontal member 31 can be firmly fixed to the horizontal member joining fitting 21.

In FIG. 7, the horizontal member 31 is the metal member 2 for connecting the horizontal members.
1 shows a state in which the horizontal member 31 is lowered and lowered until it comes into contact with the reference plate 22 of No. 1.

Next, the horizontal member 31 and the reinforcing plate 24 are connected.

As described above, when the rocket pin 26 is completely pressed into the fitting portion 32b, the horizontal member 31
The columns 41 are firmly connected to each other via the horizontal member 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 the gap, the gap 47 is filled with the adhesive 47 so that the horizontal member 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. 8 is a cross-sectional view after the adhesive 47 is filled, which is shown in the same horizontal position as FIG. 4 (b).

FIG. 9 shows one pillar 41 with four horizontal members 3
1A, 31b, 31c, and 31d are joined together in a plan view, and FIG. 10 is a perspective view showing a crossing state of bolt holes 48 formed in a pillar 41.

The above-described metal fitting 21 for joining a horizontal member, the horizontal material 31 to be joined to the metal fitting, and the joining method thereof according to the present embodiment have the following advantages that cannot be achieved by the prior art.

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

That is, by constructing the positioning section 25 with the rocket pin 26, the horizontal member 31 can be easily positioned.

Therefore, no position adjustment or the like is required when the horizontal member 31 is attached to the horizontal member joining metal fitting 21, so that the construction accuracy of the horizontal member 31 can be improved and the construction period can be greatly shortened. be able to.

Further, even if the member for mounting on the pillar 41 projects from the pillar surface, the provision of the fitting groove 34 eliminates the need to lower the horizontal member 31 after allowing the pillar 41 to escape to the side. The construction procedure can be omitted, and it is particularly advantageous when using through columns in a three-story house or the like.

A second advantage is that the rocket pin 26, which is the alignment portion 25, is fixed to the reinforcing plate 24 by welding or the like so as to also serve as joint reinforcement, and the fitting portion 32b is pre-cut with high precision. Since the rocket pins 26 are processed, the rocket pins 26 are fitted to the fitting portions 32 of the horizontal members 31.
After press-fitting into b, the horizontal member 31 and the horizontal member joining metal fitting 21
That is, the mounting strength with and is significantly improved.

Therefore, the joint strength between the horizontal member 31 and the column 41 can be remarkably increased as compared with the prior art.

That is, a vertical shearing force and a bending moment about the horizontal axis act on the horizontal member 31 due to a vertical force such as a fixed load or a load applied to the horizontal member 31, but the reference plate 22 Plate 23 and reinforcing plate 24
The shear force can be sufficiently transmitted to the column 41 by integrally configuring the.

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 defect of the cross section at all.

Further, the rocket pin 26 and the fitting portion 32
By configuring b as described above, the bending moment about the horizontal axis is applied to the pillar 41 via the metal fitting 21 for joining the horizontal members.
Can be fully communicated.

Here, the adhesive force in the shearing direction between the reinforcing plate 24 and the horizontal member 31 and the adhesive 47 can contribute to the above-described bending moment resistance force.

It is possible to prevent the horizontal member 31 from slipping upward at the same time due to the shear resistance of the adhesive 47 and the shear resistance between the rocket pin 26 and the fitting portion 32b.

Further, when a horizontal force in the pulling direction acting from the column 41 acts on the horizontal member 31, the rocket pin 26 mainly resists, and the shear resistance by the adhesive 47 also contributes to this.

The tensile force received by the rocket pin 26 is transmitted to the column 41 via the reinforcing plate 24.

Next, as shown in FIG. 11, when a horizontal force due to an earthquake or wind acts on the horizontal member 31 (acting in the direction of the white arrow in FIG. 11), the horizontal member 31 Is subject to horizontal shear forces and bending moments around the vertical axis.

In this embodiment, the rocket pin 26 is press-fitted into the fitting portion 32b, and the adhesive 47 is filled in the gap between the fitting portion 32a and the reinforcing plate 24, so that the horizontal member 31
Since the reinforcing plate 24 and the reinforcing plate 24 are integrated in the horizontal direction,
The horizontal shearing force of the horizontal member 31 is transmitted to the column 41 without causing stress concentration at a specific place.

The bending moment about the vertical axis due to the horizontal force is transmitted from the lateral bridge member 31 to the column 41 as a compressive force on the compression side (hatched arrow in FIG. 11), and is mainly pulled by the rocket pin 26 on the tension side. Acting as a force, the rocket pin 26 transmits this tensile force to the column via the reinforcing plate 24.

Therefore, it is possible to have sufficient joint strength not only for vertical force but also for horizontal force by joining the horizontal material joining metal fitting and the horizontal material according to the present embodiment. Recognize.

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

That is, as can be seen in FIG.
There is no member protruding from the upper surface of.

Therefore, when the floor plate is directly installed on the horizontal member 31 without the joists, the floor plate can be easily installed.

Further, if the floorboard is integrally constructed by using, for example, a plywood of about 28 mm, the rigidity in the horizontal plane can be increased, and in addition to the above-mentioned improvement of the joint strength, the earthquake resistance can be further increased. Depending on the design load, it is possible to omit seismic elements such as braces, firing beams, and firing bases for increasing the rigidity in the horizontal plane.

The fourth advantage is that the portion of the metal fitting 21 for joining the horizontal members to be exposed to the horizontal material 31 or the column 41 is only the reference plate 22, so that the area is the same as that of the reference plate 22 and the horizontal material 31. If a decorative plate having an equivalent appearance is attached to the outer surface of the reference plate 22 to make the lower surface of the horizontal member 31 uniform, it is possible to make the horizontal member joining metal fitting 21 completely invisible. .

Therefore, it is very advantageous for designing the beauty of the wood itself.

In the joining method of this embodiment, the connecting step of connecting the horizontal member 31 and the reinforcing plate 24 was performed with the adhesive 47. However, as shown in FIG. 12, the bolt holes 51 are provided in the reinforcing plate 24a. A horizontal fitting member 52 is prepared, and a screw or a bolt is screwed from the side of the horizontal member 31 through the bolt hole 51 to connect the horizontal member and the reinforcing plate 24a. Good.

FIGS. 13 (a) and 13 (b) show the metal member 5 for joining the horizontal members.
2 is a side view and a plan view, respectively.

FIG. 14 is a perspective view showing a horizontal member 53 to be joined to the horizontal member joining fitting 52.

Unlike the horizontal member 31 described with reference to FIG. 3, the horizontal member 53 is further provided with a bolt hole 54 through which a bolt for connecting to the reinforcing plate 24a is inserted.

The procedure for joining the horizontal member 53 to the pillar 41 by using the horizontal member joining metal fitting 52 is almost the same as the procedure described in FIG. 5, but as shown in FIG. After abutting 53 on the reference plate 22, tapping screws 55a, 55b respectively shown in FIGS. 16 and 17 are inserted from the lateral side of the horizontal member 53, and the bolt holes 51 and 54 are penetrated to reinforce the reinforcing plate 24a. The difference is that it is screwed into the horizontal member 53 on the other side.

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. 17, 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 formed.
Is firmly fixed to the bolt hole 51, and as a result, the horizontal member 53 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 bonding strength is required, the adhesive 47 and the tapping screw 5
You may use together 5a and 55b.

FIG. 18 shows a case in which a metal member 52 for connecting a horizontal member is attached to a pillar 41
19 is a view showing a state in which the horizontal member 53 is joined to the column 41, and FIG.

Further, in this embodiment, the rocket pin 26, which is the alignment portion 25, is fixed to the reference plate 22 and the reinforcing plate 24 by welding or the like so that the rocket pin 26 also serves as joint reinforcement. If the strength is small, as shown in FIG. 20, the rocket pin 26 may be separated from the reinforcing plate 24 and fixed on the reference plate 22, or as shown in FIG. It may be the joining portion 25a.

Further, in the present embodiment, the position aligning section 25 is composed of two rocket pins 26, but the number of rocket pins 26 may be adjusted according to the design joint strength.

Further, the shape of the alignment portion 25 is not limited to the rocket pin, but for example, by fixing a stiffening rib to the reinforcing plate 24 and the reference plate 22 so that they are orthogonal to each other, joint reinforcement can be achieved. The positioning section may also serve as the double-sided positioning section, or may be simply the positioning section.

Further, in this embodiment, the metal fitting 2 for joining the horizontal members is used.
Although the second alignment portion 27 is provided in the position 1, the horizontal fitting member 21 itself can be easily aligned, but in some cases, the second alignment portion 27 is used.
May be omitted.

As a modified example of the horizontal material joining metal fitting 21 of the present embodiment, FIGS.
62 is shown.

The metal fittings 61, 62 for joining the horizontal members are provided with brace attachment portions 65, 66 for attaching the horizontal brace 63 and the vertical brace 64, respectively, to the reference plate 22b and the reinforcing plate 2.
It is provided in 4b.

Further, as described above, by increasing the joint strength by using the metal fittings 21 for joining the horizontal members, seismic resistant elements such as striking beams and braces can be omitted, but the requirement of joint strength against horizontal force is required. If it is very large, or if it is desired to reduce the size of the metal fitting for joining the horizontal members, it becomes necessary to provide a brace.

On the other hand, with respect to the strength of the brace, the strength of the brace itself is less than the strength of the joint between the brace and the column or the beam, so that the prescribed seismic performance cannot be exhibited in many cases.

Such a problem is caused by the brace attaching portion 6
The problem is solved by providing 5, 66 to the metal fittings 61, 62 for joining the horizontal members.

That is, the brace mounting portions 65, 66
Since it is integrated as a part of the metal fittings 61, 62 for joining the horizontal members, a high brace joining strength can be obtained.

Note that FIG. 22 assumes the case where the horizontal member is a floor beam, a haul, etc., and FIG. 23 assumes the case where the horizontal member is a barrel, a base, etc. is there.

Although the horizontal member of the present invention has been described as being used for the horizontal member joining metal fitting of this embodiment, the reference plate for receiving the horizontal member and the upright from one side end of this reference plate. It can also be widely used in a horizontal member joining metal fitting integrally provided with a mounting plate to be attached to another structural member and a reference plate and a reinforcing plate interposed so as to reinforce the mounting plate.

That is, in the horizontal member of the present invention, a fitting portion for fitting with the reinforcing plate is formed and a position corresponding to the position of the mounting member for mounting the mounting plate to the other structural member. Since the fitting groove is provided in the side wall, it is not necessary to allow the pillar to escape to the side, and in a wooden structure with three or more floors, it is extremely easy to construct a horizontal member.

Further, the term "metal fitting" in the present invention for fitting a horizontal material, a horizontal material to be joined to the metal fitting, and a method of joining them includes metal fittings, reinforced plastics, ceramics, etc. Including those configured in.

[0130]

As described above, according to the metal fitting for joining a horizontal member, the horizontal material to be joined to the metal fitting and the joining method thereof, the horizontal material can be easily constructed. At the same time, the bonding strength can be increased.

Moreover, since the portion exposed to the wooden structural member is reduced and the portion projecting from the upper surface of the beam is particularly eliminated, it is possible to easily construct a floorboard, for example.
