1 to 3, the construction fitting 1 of the present embodiment is configured to include a receiving fitting 2, a fixing fitting 3, a pin 4, and the like. This building joint 1 for construction joins the end face of the beam 62 as the other wooden member to the side surface of the pillar 61 as one wooden member.

(Receiver bracket)
The receiving metal fitting 2 has a fixing plate 21 fixed to the side surface of the column 61 and a pair of opposing connecting plates 22 that protrude from the fixing plate 21 and are connected to the beam 62.
The fixed plate 21 is an elongated rectangular flat plate shape, and fixed holes 211 are formed at three locations in the vertical direction. In the present embodiment, the first fixing hole 211 from the top is formed at a position corresponding to the jaw hook 221, and the second and third fixing holes 211 from the top are the first fixing hole 211 from the top. in contrast, it is formed with a pitch P _1. The fixing hole 211 is a substantially circular hole into which the fixing metal fitting 3 is inserted.
Note that the number of the fixing holes 211 is usually two or more, and is appropriately set according to the size and shape of the beam 62. Further, the positions at which the respective fixing holes 211 are formed are not limited to the above positions, and are set as appropriate so as not to interfere with each other and at substantially equal intervals.

The connecting plate 22 is formed with a jaw hook 221 for locking a locking pin (drift pin) 52 on the upper beam side.
The jaw hook 221 has a structure in which the bottom is a substantially oval cutout, and the top is widened so that the top is easy to drop the locking pin 52 from above. In this way, the locking pin 52 can be easily locked to the jaw hook 221 by lowering the end of the beam 62 from the upper side toward the metal fitting 2, thereby improving workability. it can. In addition, by improving workability, it is possible to perform work at high places on the site more safely.

Further, the connection plate 22 has connection pin holes 223 for inserting connection pins (drift pins) 53 for connecting the beam 62 and the receiving metal fitting 2 at two positions below the jaw hook 221. If it does in this way, the beam 62 and the receiving metal fitting 2 can be connected by easy operation | work of driving in the connection pin 53, and workability | operativity can be improved. In the present embodiment, the upper (middle stage) connection pin hole 223 and the lower (lower position) connection pin hole 223 are formed at a pitch P ₁ with respect to the jaw hook 221. ing.
The number of the connecting pin holes 223 is usually one or more, and is appropriately set according to the size and shape of the beam 62. Further, the positions where the respective connecting pin holes 223 are formed are not limited to the above positions, and are appropriately set so as not to interfere with each other and at substantially equal intervals.

Here, preferably, as described above, a jaw hook 221 (also referred to as a first jaw hook 221) is formed on the upper portion of the connecting plate 22, and a predetermined pitch is formed downward from the first jaw hook 221. in P _1, to form a one or more (in this embodiment two) (also referred to as the first connecting pin holes 223.) connecting pin holes 223. Furthermore, chin seat 221a at the bottom of the connecting plate 22 (the second also called jaw hook 221a.) To form, from the second jaw hook 221a at a predetermined pitch P ₁ in the upward direction, the one or more (Two in this embodiment) connecting pin holes 223a (also called second connecting pin holes 223a) are formed. Further, even when the construction fitting 1 (the receiving metal 2 and the fixing metal 3 connected by the pin 4) is inverted in the vertical direction, the structure in which the fixing metal 3 does not interfere with each other, that is, the outer diameter d of the fixing metal 3. in contrast, may center distance P ₂ of the fixing hole 211 located below the second jaw hook 221a is a structure in which the P _2> d.
In this case, as will be described later, for example, even when two beams 62 are joined at right angles to the two side surfaces of the pillar 61 (and at the same height position), One of the joining metal fittings 1 (that is, the connected (integrated) receiving metal fitting 2 and fixed metal fitting 3) can be reversed and used, and the added value as a product can be improved.

  Further, the pair of connecting plates 22 has a pin hole 222 into which the pin 4 is press-fitted on the column side at a position corresponding to the fixing hole 211 (position in the vertical direction). As described above, the construction joint metal fitting 1 has a structure in which the external force acting on the fixing metal fitting 3 is received by the pair of pin holes 222 formed in the connecting plate 22. The bonding strength can be improved by the technique.

Here, the column-side end of the pin hole 222 is positioned away from the beam-side surface of the connecting plate 22 by a minute distance (usually 0.00 mm), or the press-fitted pin 4 is connected to the fixing plate 21. It is in the position to touch. If it does in this way, the depth D of the notch 622 processed into the end surface of the beam 62 can be made shallow, and the fall of the mechanical strength of the beam 62 can be suppressed. In addition, said depth D can be made shallower than the technique of the patent document 5 mentioned above.
Further, the distance between the pair of connecting plates 22 facing each other is the outer diameter d of the fixing bracket 3 + a minute distance (usually 0.00 mm) or the distance at which each connecting plate 22 contacts the fixing bracket 3. Thereby, the width W of the notch 622 processed into the end surface of the beam 62 can be shortened, and the fall of the mechanical strength of the beam 62 can be suppressed.

  As described above, the architectural fitting 1 can also improve the joint strength between the column 61 and the beam 62 by suppressing the decrease in the mechanical strength of the beam 62. Further, when the pin 4 approaches or comes into contact with the fixing plate 21 or the fixing bracket 3 approaches or comes into contact with the connecting plate 22, the mechanical strength of the fixing plate 21 or the connecting plate 22 is reinforced. The joint strength between 61 and the beam 62 can be improved.

In addition, the pair of connecting plates 22 are fitted into two grooves 621 processed on the end face of the beam 62. Further, the beam 62 is formed with a notch 622 between the two grooves 621 to avoid interference with the beam-side end portion of the fixture 3.
As described above, the pair of connecting plates 22 are connected to the beam 62 while being fitted in the two grooves 621, respectively, so that the positioning in the side surface direction of the beam 62 can be reliably performed. Further, by inserting the pair of connecting plates 22 into the grooves 621, the mechanical strength against the external force in the side surface direction of the metal fitting 2 and the beam 62 is improved.
In addition, the joining metal fitting 1 for construction can improve joint strength from the technique of said patent documents 2-4 by the structure which has a pair of opposing connection board 22. FIG.

(securing bracket)
The fixture 3 has a loading hole 31 formed at one end (column-side end) and a through-hole 32 formed at the other end (beam-side end). Is a cylindrical body (pipe) which is connected to the column 61 and whose other end is inserted into the fixing hole 211 of the receiving metal fitting 2.
In addition, in this embodiment, although it is a cylindrical body, it is not limited to this, For example, a round bar etc. may be used instead of a cylindrical body.

The insertion hole 31 is a circular hole into which the fixing pin 51 is inserted.
The through hole 32 is a circular hole into which the pin 4 is inserted. Since the pin 4 passes through the through hole 32, the fixing bracket 3 can support a large external force acting on one end side (column side), and the external force in the longitudinal direction of the beam 62 or the beam 62 can be supported. Bonding strength against external force (moment) in the vertical direction can be improved.

In addition, since the fixing bracket 3 has a simple structure, it is possible to reduce processing costs and material costs, to reduce manufacturing costs, and to improve economy.
Furthermore, in this embodiment, the center axis of the insertion hole 31 and the center axis of the through hole 32 are parallel, and when the fixing bracket 3 is connected to the bracket 2, the pin 4 is inserted into the through hole 32. Therefore, the positions of the insertion hole 31 and the driving hole 612 formed in the pillar 61 (the hole into which the fixing pin 51 is driven) are automatically matched, and workability can be improved.

Here, preferably, the length L from the end of the fixing metal 3 connected to the column 61 to the fixing plate 21 with respect to the thickness T of the column 61 is L <T / 2. Good.
Thus, since L <T / 2, for example, when the beam 62 is bonded to one side surface of the column 61, a hole (a hole in which the insertion hole 611 is extended) is formed on the side surface facing the side surface to be bonded. Since it is not exposed, durability (inhibiting rust and the like) and aesthetics can be improved. In addition, the fixing pin 51 that connects the fixing bracket 3 and the column 61 is driven from the center of the column 61 into the driving hole 612 formed on the beam side. Therefore, even when the fixing bracket 3 is connected to the same height position on the opposite side surfaces of the column 61, the pair of fixing brackets 3 can be connected to face each other without hindrance. Thereby, the joint fitting 1 for construction can improve the added value as a product.

(pin)
The pin 4 is usually a round bar made of steel and is press-fitted into the pin hole 222 of the pair of connecting plates 22 so as to be inserted into the through hole 32 of the fixing bracket 3. Are connected. In addition, the pin 4 has substantially the same length (minute) as the distance between the pair of connecting plates 22 facing each other (that is, the distance between the outer side surfaces of the connecting plate 22 and approximately W in this embodiment). An error of distance (for example, 0.00 mm) is allowed.).
Here, the pin 4 to be press-fitted is usually driven into one pin hole 222 with a hammer or the like, then inserted into the through hole 32, and then driven into the other pin hole 222. Thereby, the driven pin 4 is usually press-fitted into the pin hole 222, and both ends are pressed against the connecting plate 22. That is, welding is unnecessary and workability and the like can be improved.
In the present embodiment, the fitting between the pin hole 222 and the pin 4 is an interference fit, and the fitting between the through hole 32 and the pin 4 is a gap fit. However, the present invention is not limited to this. The fitting between the through hole 32 and the pin 4 may be an interference fit.

  In this way, since the receiving metal fitting 2 and the fixing metal fitting 3 are connected (integrated) to the construction joint metal fitting 1 by the pin 4, for example, the conventional bolt and nut tightening work is eliminated, and the fixing pin 51 is removed. By simply driving in, the integrated fixing bracket 3 and receiving bracket 2 can be attached to the column 61, and workability can be greatly improved.

(Fixing pin, locking pin and connecting pin)
The fixing pin 51, the locking pin 52, and the connecting pin 53 are substantially round bar-shaped pins having a frustoconical portion on one end side and a knurled knurled on the other end side. (Generally called a drift pin).
When the fixing pin 51 is driven into the driving hole 612 of the column 61, the fixing pin 51 passes through the insertion hole 31 of the fixing bracket 3, connects the fixing bracket 3 and the column 61, and receives the receiving bracket 2 connected to the fixing bracket 3. Is fixed to the side surface of the column 61.
The locking pin 52 is driven in advance into the driving hole 623 of the beam 62, and the connecting pin 53 is driven into the driving hole 623 after the locking pin 52 is locked to the jaw 221. .

The column 61 has an insertion hole 611 into which the fixing bracket 3 is inserted at a predetermined position on the side surface to which the receiving bracket 2 is fixed, and the center of the insertion hole 31 of the inserted fixing bracket 3. A driving hole 612 into which the fixing pin 51 is driven is formed so as to substantially coincide with the shaft.
Further, the beam 62 is formed with a pair of grooves 621 for accommodating the connecting plate 22 on the end face, and further, a notch 622 for accommodating the beam-side end of the fixture 3. Further, a driving hole 623 is formed at a position corresponding to the jaw hook 221 and the connecting pin hole 223.

Next, the joining method, joining state, etc. of the construction joint fitting 1 having the above configuration will be described.
First, as described above, the column 61 is provided with the insertion hole 611 into which the fixing metal fitting 3 is inserted and the driving hole 612 into which the fixing pin 51 is driven.
Here, as described above, the fixing bracket 3 has a length L from the end of the fixing bracket 3 connected to the column 61 to the fixing plate 21 with respect to the thickness T of the column 61. <T / 2, and the depth of the insertion hole 611 is the depth up to the approximate center of the column 61. Thereby, for example, when the beam 62 is joined to one side surface of the column 61, a hole (a hole obtained by extending the insertion hole 611) is not exposed on the side surface opposite to the side surface to be joined. ) And aesthetics can be improved.

  Further, as described above, the beam 62 has two grooves 621 and a notch 622 formed in the end surface, and a driving hole 623 into which the locking pin 52 and the connecting pin 53 are driven is formed. Subsequently, the locking pin 52 is driven into the driving hole 623 corresponding to the jaw hook 221.

Moreover, the receiving metal fitting 2 and the fixing metal fitting 3 are connected by a pin 4 to be press-fitted. That is, the end of the beam side of the fixing bracket 3 is inserted into the fixing hole 211, and then the pin 4 is driven into one of the pin holes 222 with a hammer or the like, and then inserted into the through hole 32. Then, it is driven into the other pin hole 222.
Here, as described above, the column-side end of the pin hole 222 is positioned away from the beam-side surface of the connecting plate 22 by a minute distance (usually 0.00 mm) or the press-fitted pin 4. Is in a position in contact with the fixed plate 21. The distance between the pair of connecting plates 22 facing each other is the outer diameter d of the fixing bracket 3 + a minute distance (usually 0.00 mm) or the distance at which each connecting plate 22 contacts the fixing bracket 3. In other words, according to the architectural fitting 1, the depth D of the notch 622 can be made shallower and the width W of the notch 622 can be made shorter than the technique of Patent Document 5 described above. Thereby, the fall of the mechanical strength of the beam 62 can be suppressed, and as a result, the joint strength between the column 61 and the beam 62 can be improved. Further, when the pin 4 approaches or comes into contact with the fixing plate 21 or the fixing bracket 3 approaches or comes into contact with the connecting plate 22, the mechanical strength of the fixing plate 21 or the connecting plate 22 is reinforced. The joint strength between 61 and the beam 62 can be improved.

Further, as described above, the pin 4 to be press-fitted is usually driven into one pin hole 222 with a hammer or the like, then into the through hole 32, and then driven into the other pin hole 222. It is. That is, since the receiving metal fitting 2 and the fixing metal fitting 3 are connected (integrated) to the construction joint metal fitting 1 by the pins 4, for example, conventional bolt and nut tightening operations are eliminated, and workability is improved. be able to. In addition, when the pin 4 is driven, both ends are crimped to the connecting plate 22, welding is not required, and workability and the like can be improved. In addition, although the pin 4 is press-fitted using a hammer etc., the means to press-fit is not specifically limited.
By the way, the above steps are usually performed in a factory and can be performed safely and with good workability.

  Next, the column 61, the beam 62 into which the locking pin 52 is driven, the receiving metal fitting 2 and the fixing metal fitting 3 connected by the pin 4 are transported to the construction site. At this time, since the pillar 61 and the beam 62 to which the receiving metal fitting 2 and the fixing metal 3 are not attached at all can be conveyed to the construction site, the conveying efficiency can be improved, and the receiving metal 2 and the fixing metal 3 can be improved. It is possible to prevent the problem that the wood comes into contact with the wood and the wood is damaged.

Next, the three fixing brackets 3 connected to the receiving bracket 2 are inserted into the insertion holes 611 of the columns 61. Subsequently, when the fixing pin 51 is driven into the driving hole 612 of the column 61 and the insertion hole 31 of the fixing bracket 3, the fixing bracket 3 is connected to the column 61, and the receiving bracket 2 is attached to the side surface of the column 61. Fixed. At this time, since a bolt or the like is not used, a dedicated tightening tool (such as a box wrench) is not required, and workability can be greatly improved.
In addition, although fixing to the pillar 61 of the metal fitting 2 is normally performed at a construction site, it is not limited to this, For example, it can also be performed in a factory.

Next, the pillar 61 to which the metal fitting 2 is fixed is erected on a foundation (not shown) at the construction site.
Subsequently, the beam 62 is moved in the direction of the column 61, the connecting plate 22 is inserted into the groove 621, the beam 62 is further lowered, and the locking pin 52 is locked to the jaw 221.
Next, when the connecting pin 53 is driven into the driving hole 612 of the beam 62 (the driving hole 612 corresponding to the connecting pin hole 223), the connecting pin 53 penetrates the connecting hole 223 and the beam 62 is joined to the column 61. Is done.
Note that the architectural fitting 1 is fixed by the fixing pin 51 being driven, so that the fixing plate 21 of the receiving metal 2 is pressed against the side surface of the column 61, and the connecting pin 53 is driven. In the state where the end surface of the beam 62 is pressed against the side surface of the column 61, the beam 62 is joined. Thereby, the column 61 and the beam 62 are joined in a close contact state.

Next, a usage example of the present embodiment will be described with reference to the drawings.
FIG. 4: has shown the schematic plan view for demonstrating the usage example of the joining metal fitting for construction concerning 1st embodiment of this invention.
FIG. 5 is a cross-sectional view taken along the line AA in FIG.
4 and 5, the two metal fittings 1 for construction of the present embodiment have two beams 62 (the right beam 62 and the front side) on the two side surfaces of the column 61 (and at the same height position). It is used when the beams 62) are joined at right angles, and the building joint 1 for joining the beams 62 on the front side is inverted in the vertical direction as compared with the building joint 1 on the right side. It is used.

First, as described above, the column 61 has the insertion hole 611 into which the right fixing bracket 3 is inserted on the right side surface, and the pitch P ₂ on the front side surface compared to the right side. Only in the lower position, an insertion hole 611 into which the front-side fixing bracket 3 is inserted is formed. Further, driving holes 612 for connecting the right side fixing bracket 3 and the front side fixing bracket 3 to the column 61 are also formed.
Note that, as described above, since the construction fitting 1 for the construction satisfies P ₂ > d, the fixing bracket 3 on the front side does not interfere with the fixing bracket 3 on the right side.

  Similarly to the right beam 62, the front beam 62 has two grooves 621 and a notch 622 formed in the end surface, and a driving hole 623 into which the locking pin 52 and the connecting pin 53 are driven is formed. Established. Subsequently, the locking pin 52 is driven into the driving hole 623 corresponding to the jaw hook 221a.

Next, the three fixing fittings 3 connected to the receiving fitting 2 are inserted into the insertion holes 611 on the front side of the pillar 61. Subsequently, when the fixing pin 51 is driven into the driving hole 612 of the column 61 and the insertion hole 31 of the fixing bracket 3, the fixing bracket 3 is connected to the column 61, and the receiving bracket 2 is connected to the front side of the column 61. Fixed to the side of the. However, as described above, the building joint 1 on the front side is fixed to the column 61 in a state where the building joint 1 on the right side is inverted in the vertical direction.
Subsequently, the beam 62 on the front side is moved in the direction of the column 61, the connecting plate 22 is inserted into the groove 621, the beam 62 is further lowered, and the locking pin 52 is locked to the jaw hook 221a.
Next, when the connecting pin 53 is driven into the driving hole 612 of the beam 62 (the driving hole 612 corresponding to the connecting pin hole 223a), the connecting pin 53 penetrates the connecting hole 223a, and the beam 62 on the front side becomes the column. 61 is joined.

As described above, the architectural fitting 1 of the present embodiment has two beams 62 (the right beam 62 and the front beam 62) on the two side surfaces of the column 61 (and at the same height position). Even when joining at right angles, it is possible to use one of the two construction fittings 1 (that is, the connected (integrated) receiving metal fitting 2 and fixed metal fitting 3) inverted in the vertical direction. It is possible to improve the added value as a product.
In addition, as above-mentioned, as for the joining metal fitting 1 for construction, with respect to the thickness T of the pillar 61, the length L from the edge part of the pillar side of the fixing bracket 3 connected to the pillar 61 to the fixing plate 21 is obtained.
