[0002]
[Prior art]
As shown in FIG. 15, the shaft construction method using wood called the conventional construction method uses a method in which tenons 110 are formed on both ends of the pillar 100, and a joint fitting 200 is used as shown in FIG. What was there was common. In FIGS. 15 and 16, 300 is a base, 400 is a beam, and 500 is a connecting reinforcing plate.

[0020]
DETAILED DESCRIPTION OF THE INVENTION
The wood joint according to the present invention is a state in which the pipe-shaped joint body embedded in the hole formed in the wood, the adhesive for fixing the joint body in the hole, and the exposed end faces of the joint body are attached to each other. And a coupling means for coupling the joint bodies together.
[0021]
The connecting means may be configured to include a tightening fitting having a threaded portion, for example, a bolt or a nut.
[0022]
That is, it is preferable that the tightening bracket has a male screw part and a female screw part, and the female screw part can be formed on the inner peripheral surface of the pipe-shaped joint body. In addition, although the metal can be considered as a material of the joint body, a synthetic resin or the like can also be used if the strength is sufficient.
[0023]
In addition, an epoxy resin-based adhesive can be suitably used as the adhesive, but the material is not particularly limited, and any adhesive can be used as long as the joint body and the wood can be bonded substantially integrally.
[0024]
By adopting the above configuration, the strength of compression and pulling in the direction perpendicular to the fiber direction in wood, which had a problem with strength in the past, has been remarkably improved, and the strength of steel structures is expected at the joints between columns and beams. It can be done.
[0025]
That is, when joining wood using the above wood joints, a pipe-like joint body is inserted into a transverse hole drilled in a direction perpendicular to the fiber direction of the wood, and the end face of the joint body is exposed. In the state where the joint body is inserted into a vertical hole drilled in a substantially axial direction from the end of the wood, and the end face of the joint body is exposed with the adhesive. To fasten and join the two pieces of wood, with the end faces of the joint body abutting each other, a bolt is inserted from the transverse hole side and screwed into the female screw formed in the joint body on the vertical hole side and tightened Good.
[0026]
The bolt tightening force is not applied to the wood, but to the joint bodies that are embedded and fixed to the wood with an adhesive, so there is no risk that the wood will bend due to the bolt's tightening force and be joined with a constant tightening force. It becomes possible.
[0027]
Therefore, it is possible to realize a structure that had a problem with strength if it had not been a conventional steel structure with wood, and it was able to withstand earthquakes, etc., and to make use of the warmth and graininess of wood. Housing can be provided.
[0028]
By the way, as said connection means, it can also be set as the structure which comprises the steel wire for fastening.
[0029]
That is, the longitudinal hole is formed over the entire longitudinal length of the wood, and one of the timbers is a hollow wood, and a piano wire or the like is inserted between the longitudinal hole and the transverse hole of the other wood, and this is performed with a certain force. It is tense and increases the strength of the whole wood like prestressed concrete.
[0030]
As described above, since sufficient strength can be imparted even with wood, the use of wood is remarkably expanded.
[0031]
Moreover, short wood can be continuously connected in an arch shape using the steel wire for tightening, and a linear structure can be constructed.
[0032]
Furthermore, the above-described connecting means may be configured to include a connecting metal fitting pinned to the joint body.
[0033]
In other words, a joint body with a pin hole in the peripheral surface is inserted into a vertical hole drilled in a substantially axial direction from the end of the wood, and is fixed with an adhesive with the end face of the joint body exposed. In order to join the wood provided with the vertical holes, the connecting metal fitting with the through hole corresponding to the pin hole is inserted between the two vertical holes, and the end faces of the joint body are in contact with each other, the connection In this method, the metal fittings are pinned to the joint body on both wood sides.
[0034]
Alternatively, a pipe-shaped joint body is inserted into a transverse hole drilled in a direction orthogonal to the fiber direction of the wood, and is fixed with an adhesive with the end face of the joint body exposed, and is substantially from the mouth of the wood. Inserting a joint body with a pin hole in the peripheral surface into a longitudinal hole drilled in the axial direction, and fixing it with an adhesive with the end face of the joint body exposed, to join both pieces of wood together In addition, a connecting fitting provided with a through hole corresponding to the pin hole is inserted between the transverse hole and the longitudinal hole, and one end side of the connecting fitting is faced to each other with the end faces of the joint body being in contact with each other. It is screwed to the joint body inside, and is pinned to the joint body inside the longitudinal hole.
[0035]
According to the method using such a joint, construction at the site can be easily performed. Here, the term “pin” is used as a concept including a so-called generally pin-shaped one and a wedge-shaped one.
[0036]
By the way, it is preferable that the joint body is provided with a spiral groove on the outer peripheral surface thereof so that the adhesive is spread over the entire gap between the joint body and the hole and functions as a retaining body for the joint body.
[0037]
By using the joint body having such a configuration, the adhesion to the wood is strengthened, and a more reliable joint strength can be obtained.
[0038]
As described above, if the above-mentioned timbers are made of pillars and beams, the wooden house of the ramen structure will be as strong as a steel structure, and will have a large seismic resistance, as well as a high bonding strength. The degree of freedom in design will increase, and it will be possible to provide large wooden houses that could not be realized in the past.
[0039]

It is screwed into a female screw 43 formed in the joint body 4 on the vertical hole 21 side, and tightened with a predetermined torque. The tightening force by the bolt 45 is applied only to the joint body 4, and the joining can be performed with a sufficient force without the column 3 being recessed.
[0049]
Further, when connecting the pillar 3 to the base 1, a wood joint A is used.
[0050]
That is, as shown in FIGS. 1 and 3, a male thread 11a is formed at the tip of the anchor 10, and a connecting pipe 6 having a female thread 60 formed on the inner peripheral surface is formed on the anchor 10 at its lower end. Screw until it abuts against block C. The connecting pipe 6 is longer than the thickness of the base 1, and the end protrudes from the base 1.
[0051]
And the base 1 is mounted so that the said connection pipe | tube 6 may be penetrated in the joint main body 4 embed | buried in the cross hole 12 formed so that the fiber direction of the base 1 may be crossed previously.
[0052]
Next, a pillar 3 (in this case, a spacer 3 '' in this case) in which a longitudinal hole 31 '' is formed in advance and the joint body 4 is fixed with an adhesive 5 in the longitudinal hole 31 '' is erected. That is, a long-axis bolt 46 is inserted into the joint body 4 of the column 3, and the long-axis bolt 46 is screwed into the connecting pipe 6 to connect the column 3 to the base 1 with a sufficient connecting force. is there. 46a is a minus groove provided at one end of the long bolt 46. In this case, a space 4a is provided in the lower end portion of the joint body 4 embedded in the intermediate post 3 '' so that the connecting pipe 6 can be loosely fitted.
[0053]
If necessary, the beam 2 is passed to the stud 3 ''. Here, a cross hole 21 'is provided in the beam 2, and the joint body 4 is inserted and fixed in the cross hole 21'. The connecting pipe 6 ′ having an internal thread 60 formed on the inner peripheral surface thereof is inserted through and inserted into the long-axis bolt 46 using the minus groove 6′a.
Similarly, the interstice 3 '' is in contact with the upper part of the beam 2, and the beam 2 is horizontally mounted on the uppermost part of the column 3. In this case, the beam 2 and the stud 3 '' are connected to each other by using a bolt 47 in which a hole portion in which the female screw 60 is formed is provided at the tip portion. A bolt insertion recess 22 is formed in the beam 2.
[0054]
In addition, this kind of bolt 47 can also be used for joining with the base 1, as shown in FIG.
[0055]
That is, if the pillar 3 is erected at a place where the anchor 10 is not provided, a transverse hole 12 is appropriately provided in the base 1 and the bolt 47 is inserted in advance in the transverse hole 12 on the foundation block C. The base 1 is placed, and the female screw 60 of the bolt 47 and the long-axis bolt 46 are screwed together. Of course, the bolt 47 is provided with a detent 47a.
[0056]
By the way, as can be seen from FIG. 3, the length of the joint body 4 can be arbitrarily set, and the length is determined in accordance with a desired strength. Further, for example, in the pillar 3 or the like, the joint body 4 having an appropriate length can be embedded in a place where there is a risk of buckling.
[0057]
As another embodiment of the present embodiment, the wood joint A can be configured as shown in FIG.
[0058]
In other words, in the joint body 4 on the column 3 side (transverse hole 31 side), a metal or resin insert 48 having a sufficient strength formed longer than the cross hole 31 is slidably disposed. The joint body 4 on the beam 2 side is provided with a recess 49 for inserting the tip of the insert 48. When the bolt 45 is screwed, the joint bodies 4 and 4 are brought into contact with each other, and the insert 48 is inserted into the recess 49, The insert 48 can receive the force in the shearing direction of the joint.

In the figure, reference numeral 79 denotes a closing member for closing the pin insertion hole 76 'provided on the wood side.
[0066]
The wood joint A according to this embodiment can be easily joined between the beams 2 and the columns 3 and is not visible from the outside as in the previous embodiment, so that the aesthetic appearance is not impaired.
[0067]
Such a wood joint A can be used for any application by slightly changing the form. For example, as shown in FIG. 8, a joint having a hole portion in which a bolt portion 77 is formed on one side of the swivel portion 71 for preventing rotation in the connection fitting 7 and a female screw portion 43 ′ corresponding to the bolt portion 77 is formed. The main body 4 is embedded in the foundation block C, and the base 1 on which the joint body 4 is embedded and fixed is placed so that the joint bodies 4 are brought together.
[0068]
Then, as shown in FIG. 6 and FIG. 7, the connecting metal 7 extending upward from the base 1 is inserted into the wood (here, the pillar 3) in which the joint body 4 is embedded, and the pin is operated in the same procedure as described above. The pillar 3 can be firmly connected by being stopped.
[0069]
Further, although not shown, this wood joint A can also join the beam 2 and the column 3.
[0070]
That is, a joint body 4 provided with a female thread is inserted and fixed in a transverse hole 31 drilled in a direction perpendicular to the fiber direction of the column 3, and a vertical hole 21 drilled in a substantially axial direction from the wood face 20 of the beam 2. The joint body 4 having pin holes 76, 76a provided in the peripheral surface thereof is inserted and fixed therein, and the connecting fitting 7 is inserted between the transverse hole 31 and the longitudinal hole 21, and the end faces 40 of the joint body 4 are connected to each other. One end side of the connecting fitting 7 is screwed to the joint body 4 in the transverse hole 31 of the column 3 in the butted state, and is pinned to the joint body 4 in the longitudinal hole 21 of the beam 2.
[0071]
Furthermore, one form of the joining method using the wood joint A according to the present embodiment will be described. As shown in FIG. 9, a four-way coupling joint body 4 ′ having a cross-shaped female screw hole 90 formed in a cross-sectional plan view is embedded and fixed in the core of the pillar 3, and each female screw of the joint body 4 ′ is fixed. The connecting metal fitting 7 provided with the bolt part 77 described above is screwed into the hole 90. According to this joining method, four beams 2 can be connected to one column 3 in four directions at the same height.
[0072]
In FIG. 9, a guide piece 91 having a substantially cross shape in cross-section is provided so as to surround the four-way connection joint body 4 ′, and the rotation of the end face portion of the guide piece 91 and the connection fitting 7 is prevented. Although the end surface of the bulging portion 71 is in surface contact, this is not necessarily required.
[0073]
As described above, according to the joining method using the wood joint A according to the present embodiment, the application can be expanded and the construction at the site can be easily performed.
[0074]
(Third embodiment)
Next, as a third embodiment, a wood joint A shown in FIGS. 10 and 11 and a usage pattern thereof will be described.
[0075]
In this configuration, a fastening steel wire 92 is provided as a connecting means. As the tightening steel wire 92, a piano wire or the like may be used.
[0076]
As shown in FIG. 10, in this embodiment, the structure of the joint portion on the column 3 side is in accordance with the first embodiment shown in FIG.
[0077]
The difference lies in the structure of the joint portion on the beam 2 side, in which the joint body 4 is embedded and fixed at a position deeper than the end face 20, and the female screw 43 formed on the inner peripheral surface in the vicinity of one end of the joint body 4 is different. In addition, the auxiliary joint 13 is screwed so that the end face 13a of the auxiliary joint 13 is flush with the end face 20.
[0078]
The auxiliary joint 13 has a reduced diameter portion 13b and an enlarged diameter portion 13c. A male screw 14 is provided on the outer peripheral surface of the reduced diameter portion 13b and screwed into the female screw 43. Further, a screw rod 15 is screwed into the core portion of the reduced diameter portion 13b, and the engagement end portion 92a of the tightening steel wire 92 is engaged with the screw rod 15 inside.
[0079]
Further, the diameter of the enlarged diameter portion 13c is equal to the outer diameter of the joint body 4, and a female thread portion 17 is formed in the core portion of the enlarged diameter portion 13c to be screwed with the male screw 44 of the bolt 45 from the column 3 side. doing.
[0080]
With this configuration, if the screw rod 15 is turned so as to move to the end face 20 side with a tool, the fastening steel wire 92 is pulled and becomes in tension, and the beam 2 is subjected to a high load as if it is prestressed concrete. It will be tolerable.
[0081]
By joining the beam 2 and the column 3 as described in the first embodiment, a stronger horizontal mounting of the beam 2 is possible.
[0082]
FIG. 11 shows another embodiment of the present embodiment.
[0083]
This is because the bolt 47 on the column 3 side is provided with a hole in which a female screw 60 as shown in FIG. 3 is formed at the tip, and an auxiliary joint having a male screw portion 93 that is screwed into the female screw 60. 16 is inserted into the joint body 4 on the beam 2 side, and the auxiliary joint 16 is formed with an engaging portion 94, and the engaging portion 94 is engaged with the engaging end portion 92a of the tightening steel wire 92. I am letting.
[0084]
Reference numeral 95 is a guide hole provided in the auxiliary joint 16. When the engagement pin 96 is disposed in the guide hole 95 and the bolt 47 is turned, the auxiliary joint 16 is guided by the guide hole 95 and the auxiliary joint 16 is moved to the front end 20. As described above, the fastening steel wire 92 is pulled and becomes in tension, and the beam 2 can withstand a high load as if it were prestressed concrete.
[0085]
In addition, in this form, tenon H is provided and the adhesiveness of the beam 2 and the pillar 3 is improved more, but this tenon H can be employ | adopted in each Example mentioned above.
[0086]
Further, if the above-described fastening steel wire 92 is used, the frame structure B shown in FIG. 1 can be easily assembled.
[0087]
That is, as shown in FIG. 12, when a large number of short timbers B1 are joined in the axial direction, the joint body 4 is embedded and fixed to each short timber B1 as described above, and is attached to the end face 20 so as to have an arch shape. It is cut at an angle, butted together and joined.
[0088]
Due to the tightening force of the tightening steel wire 92, the arched frame structure B has sufficient strength.
[0089]
In the figure, 97 is a guide disposed in the vicinity of the joining portion of the short wood B1 so that the fastening steel wire 92 is not suddenly broken, and 98 is joined so as to reinforce the joining portion. It is a joint fitting passed between both short timbers B1, and is bent and formed into a mountain shape at an angle that matches the joint angle between the short timbers B1.
[0090]
As described above, the present invention has been described through the respective embodiments. However, according to the present invention, in the joint portion, which has been regarded as a problem in the past, the defect of the wood that was extremely weak against the force in the direction orthogonal to the fiber direction is eliminated. It became possible to join with the strength of a steel frame. Therefore, it is possible to provide wooden houses with no problems in strength, and demand will be stimulated even for soft timber, such as cedar, that has been considered unsuitable for building materials. This is a great merit.
[0091]
Further, by solving the strength problem, the use of wood is greatly expanded. For example, as shown in FIG. 13, the wood W using the wood joint A according to the present invention is replaced with a steel frame. If it is arranged around it so as to hold S, it can be used as a pillar material for large-scale structures such as gymnasiums.
[0092]
Moreover, the wood W is more resistant to fire than the steel frame S and can protect the internal steel frame S from fire until it is completely carbonized. Therefore, the steel frame S can be prevented from being bent at a high temperature, and the structure collapses. It is also possible to prevent major damage. In addition, the adhesive agent 5 employ | adopted in each Example can be used for adhesion | attachment between each timber W and the steel frame S. FIG.
[0093]
By the way, as the wood for embedding the wood joint A according to the present invention, a sufficiently dried hollow wood as disclosed in JP-A-9-256467 can be suitably used.
