[First embodiment]
FIG. 1: has shown the schematic perspective view of the joining metal fitting for construction concerning 1st embodiment of this invention.
In the figure, a construction fitting 1 is a fitting that joins a beam 6 that is a cross member to a column 5 that is a vertical member, and is connected to the connecting fitting 2 that is fixed to the beam 6 and the column 5. The receiving metal fitting 3 and the connecting pin 4 for connecting the connecting metal fitting 2 and the receiving metal fitting 3 are provided.
In addition, although the example which joins the beam 6 to the pillar 5 is demonstrated, of course, the wooden member joined by each metal fitting in this invention is not limited to this example.

(Connecting bracket)
As shown in FIG. 1, the connecting fitting 2 includes a metal fixing plate 21, a pair of side plates 22 and 23, a receiving plate 24, a locked pin 25, and a hiring fitting 26.
The fixing plate 21 is a rectangular vertically long metal plate in which a bolt hole 211 into which the bolt 28 is inserted is provided in the center and the lower portion.

  The side plates 22 and 23 are a pair of rectangular vertically long metal plates that project at right angles from both lateral ends of the fixed plate 21. Generally, the side plates 22 and 23 are formed by pressing from a single plate together with the fixed plate 21. Further, the side plates 22 and 23 are provided at the top thereof with the locked pins 25 engaged with the locking portions 322 of the receiving metal fitting 3 fixed at both ends. In the present embodiment, the latched pin 25 is inserted into a through-hole penetrating the side plates 22 and 23. The locked pin 25 is detachably attached to the side plates 22 and 23. Further, the side plates 22 and 23 have a connecting pin hole 231 into which a connecting pin 4 for connecting to the receiving metal fitting 3 is inserted so as to penetrate above and below the central portion (position substantially divided into three in the longitudinal direction). It is.

  Further, in the connection fitting 2, the receiving plate 24 protrudes from the lower part of the fixed plate 21 toward the beam 6 at a substantially right angle. In the present embodiment, a rectangular metal plate is butt welded to a part of the fixed plate 21 and the side plates 22 and 23 on the beam 6 side. If it does in this way, in the state where beam 6 was laid in receiving plate 24, receiving plate 24 can support beam 6, and beam 6 and receiving metal fitting 3 will be joined more firmly. Therefore, the joint strength between the beam 6 and the column 5 can be improved.

  The connecting fitting 2 is fixed to the end face of the beam 6 via a bolt 28, a hiring fitting 26 and an hiring fitting fixing pin 27. The hiring bracket 26 is chamfered so that one end portion can be easily inserted into the mounting hole, and a fixing hole 262 into which the hiring bracket fixing pin 27 is inserted is formed in the one end portion. This is a metal round bar in which a female screw 261 to which a bolt 28 is tightened (screwed) is cut. Further, the hiring bracket fixing pin 27 has a structure substantially similar to that of the connecting pin 4, and one end thereof is a substantially round cone-shaped metal round bar, and the surface of the round bar has a non-slip knurled surface. It has been given.

  Although not shown in the drawing, the beam 6 has a mounting hole into which the metal fitting 26 is inserted at a position corresponding to the bolt hole 211 on the end surface (a plane on which a normal cutting process is performed) on the side joined to the column 5. Further, a pin hole into which the hiring bracket fixing pin 27 is inserted is formed at a position corresponding to the fixing hole 262 from the side surface. The hiring fitting 26 is inserted into the mounting hole, and the hiring fitting fixing pin 27 is inserted into the fixing hole 262 so that the hiring fitting 26 is fixed to the beam 6. In the connection fitting 2, with the beam 6 placed on the receiving plate 24 and the fixing plate 21 in contact with the end face of the beam 6, the bolt 28 is inserted into the bolt hole 211 and tightened into the female screw 261 of the employment fitting 26. Is fixed to the beam 6 (see FIGS. 2 and 4). In this way, the fixing structure of the connecting fitting 2 is simplified, the manufacturing cost of the construction fitting 1 is reduced, and it is not necessary to process grooves or notches on the end face of the beam 6. Costs can be reduced.

(Connecting pin)
As shown in FIG. 1, the connecting pin 4 is a metal round bar having a truncated cone shape at one end, and the surface of the round bar is knurled to prevent slipping.

(Receiver bracket)
As shown in FIG. 1, the metal fitting 3 includes a metal fixing plate 31, a pair of side plates 32 and 33, and a sleeve 321.
The fixing plate 31 is a rectangular vertically long metal plate in which bolt holes 311 into which the bolts 34 are inserted penetrate the upper portion, the central portion, and the lower portion. The bolt hole 311 is provided at a position in the height direction where the screw tip of the bolt 34 and the nut 36 do not interfere with the sleeve 321. This makes it possible to reduce the amount of protrusion of the bracket 3 from the pillar 5 (the lateral width of the side plates 32 and 33). When the pillar 5 to which the bracket 3 is fixed is transported to the construction site in the factory, the pillar 5 loading efficiency is improved.

  Further, the receiving metal fitting 3 has new bolt holes 311 penetrating below the three bolt holes 311 at intervals at which the bolt holes 311 do not interfere with each other. As a result, even when the bracket 3 is fixed at the same height position on the orthogonal surfaces of the pillars 5, the bolts 34 inserted into the three bolt holes 311 and the new three bolt holes 311 are inserted. The trouble that the bolt 34 to be interfered can be avoided, and the usability of the metal fitting 3 is improved.

  The side plates 32 and 33 are a pair of rectangular vertically long metal plates that project at right angles from both lateral ends of the fixed plate 31. In general, the side plates 32 and 33 are formed together with the fixed plate 31 by pressing from a single plate. Further, the side plates 32 and 33, the fixing plate 31 and the sleeve 321 are configured to be fitted between the side plates 22 and 23 of the connecting metal fitting 2, and when the locked pin 25 is locked to the locking portion 322, the side plate 32 and 33 are smoothly inserted between the side plates 22 and 23.

  Further, the side plates 32 and 33 are formed with locking portions 322 in the form of substantially elongated holes with the upper portions opened, into which the locked pins 25 of the connecting fitting 2 are engaged. Further, in the side plates 32 and 33, the sleeve 321 into which the connecting pin 4 for connecting to the connecting metal fitting 2 is inserted does not protrude outward from the side plates 32 and 33 at a position corresponding to the connecting pin hole 231. It is built in. In this embodiment, a sleeve 321 is inserted into a through-hole penetrating the side plates 32 and 33, and the inner surfaces of the side plates 32 and 33 and the sleeve 321 are spot welded. In this way, when the connection pin 4 is inserted into the connection pin hole 231 and the sleeve 321 of the connection fitting 2, the connection pin 4 is guided by the sleeve 321, so that the connection pin 4 can be easily inserted. . Further, since this loading work is usually a high-place work, the ability to easily insert the connecting pin 4 is extremely effective in improving the safety of the work. Furthermore, since the sleeve 321 functions as a reinforcing member, the mechanical strength of the metal fitting 3 can be further strengthened.

  The metal fitting 3 is fixed to the side surface of the column 5 via a bolt 34, a flat washer 35 and a nut 36. Although not shown, the pillar 5 has a bolt hole into which the bolt 34 is inserted at a position corresponding to the bolt hole 311 on the side surface. In the receiving metal 3, the bolt 34 in which the flat washer 35 is inserted is inserted from the opposite side surface of the column 5, and the bolt hole 311 of the receiving metal 3 is inserted in the tip of the bolt 34 protruding from the column 5. When the nut 36 is tightened, it is fixed to the column 5 (see FIGS. 2 and 4).

Next, the joining procedure of the construction joint fitting will be described with reference to the drawings.
FIG. 2: has shown the schematic perspective view for demonstrating the joining procedure of the joining metal fittings for construction concerning 1st embodiment of this invention.
In the figure, as described above, the connecting metal fitting 2 is fixed to the beam 6 and the receiving metal fitting 3 is fixed to the column 5.
First, the connecting metal fitting 2 is moved horizontally to the column 5 side and lowered when the locked pin 25 is positioned above the locking portion 322, and the locked pin 25 is locked to the locking portion 322. At this time, the connection fitting 2 is inserted in a state in which the inner surfaces of the side plates 22 and 23 are substantially in contact with the outer surfaces of the side plates 32 and 33. Further, since the connecting fitting 2 is fixed so as to protrude from the end face of the beam 6 and can be clearly seen from above and from the side, the safety of the operation of locking the locked pin 25 to the locking portion 322 is improved. To do.

FIG. 3: has shown the schematic perspective view for demonstrating the joining state of the joint fitting for construction concerning 1st embodiment of this invention.
In the figure, the connecting pin 4 is driven into the connecting pin hole 231 and the sleeve 321 so that the front end portion and the rear end portion of the connecting pin 4 protrude by substantially the same distance.
Here, the operation of inserting the connection pin 4 into the connection pin hole 231 and the sleeve 321 is performed by inserting the connection pin hole 231 and the sleeve 321 located further inside the gap between the beam 6 and the column 5 into the tip of the connection pin 4. Since this is an operation that requires skill such that the connecting pin 4 is driven so that the portion and the rear end protrude by substantially the same distance, a driving jig 41 shown in FIG. 4A may be used. The driving jig 41 includes a cylinder 412 into which the connecting pin 4 is inserted, and a round bar 411 that is welded and fixed in a state of being inserted into the cylinder 412 while leaving a preferable protruding amount c of the connecting pin 4. When this driving jig 41 is used, the connecting pin 4 is attached to the cylinder 412, so that the connecting pin 4 can be positioned by grasping the round bar 411, and the rear end of the round bar 411 can be hit with a hammer. it can. Further, when the tip of the cylinder 412 comes into contact with the side plate 23, the connecting pin 4 is not driven any more, so that it is possible to avoid the problem that the connecting pin 4 is driven too much and improve the safety of work at high places. Can be made.

  Further, in the connecting metal fitting 2, the locked pin 25 is detachably attached to the side plates 22 and 23, and the tightened bolt 28 is connected to the sleeve 61, the bolt 34 and the beam 36 side of the nut 36. positioned. That is, when the locked pin 25 and the connecting pin 4 are removed from the state in which the beam 6 is joined to the column 5, the connecting fitting 2 fixed to the beam 6 can be moved downward. Therefore, the joined beam 6 can be pulled down, and the beam 6 can be removed downward even in a remodeling operation or the like even when a space for pulling out the beam 6 cannot be secured. Usability is greatly improved.

  As described above, the architectural fitting 1 according to the present embodiment can easily perform the joint processing to the beam 6. That is, for example, it is only necessary to process a hole (and a hole) into which the hiring fitting 26 and the hiring fitting fixing pin 27 are inserted, and groove processing or notch machining as a general (conventional) closing processing is performed. Since it is not necessary to carry out, it is possible to reduce the cost of processing the joint. Further, since the receiving plate 24 supports the beam 6, the bonding strength between the beam 6 and the column 5 can be strengthened. Furthermore, since the connecting pin 4 is guided by the sleeve 321 when the connecting pin 4 is inserted, the connecting pin 4 can be easily inserted, and the safety of work at high places can be improved. In addition, the joined beam 6 can be pulled downward, improving usability.

  Further, preferably, as shown in FIGS. 4B and 4C, a protruding portion 3211 protruding in the center line direction of the sleeve 321 is formed at one location of the cylindrical sleeve 321, and the protruding portion 3211 The distance a to the inner surface of the sleeve 321 facing the protruding portion 3211 may be shorter than the diameter D of the connecting pin 4 (a <D). In addition, the diameter d of the front-end | tip part of the connection pin 4 is made shorter than the distance a (d <a). If it does in this way, when the inserted connecting pin 4 contacts the protrusion part 3211, it will receive a pressing force from the elastically deformed protrusion part 3211, and it will prevent that the connecting pin 4 pulls out easily.

  More preferably, as shown in FIG. 4D, two projecting portions 3211 and 3212 are formed, and the first projecting portion 3211 is disposed on one end side from the longitudinal center portion of the sleeve 321. Further, the second protrusion 3212 may be formed on the other end side of the longitudinal center of the sleeve 321 and at a position opposite to the center line of the sleeve 321 by 180 degrees. In this way, the two opposing protrusions 3211 and 3212 exert an elastic force in the direction of the center line of the sleeve 321, and the distance a ′ between the protrusions 3211 and 3212 is d <a ′ <a <D. Therefore, it is possible to more reliably prevent the connecting pin 4 from coming off.

Moreover, FIG. 9 has shown the schematic side view for demonstrating the joining state of the joint fitting for construction concerning 3rd embodiment of this invention.
8 and 9 is different from the first embodiment described above in that there is no receiving plate 24 for the connection fitting 2b and a support member 241 is provided instead.
The other structures are substantially the same as those of the first embodiment, and the same structures are denoted by the same reference numerals as those of the first embodiment in the drawings, and detailed description thereof is omitted.

(Connecting bracket)
As shown in FIGS. 8 and 9, the connection fitting 2 is configured to include a support member 241 that protrudes from the fixing plate 21 toward the beam 6 at a substantially right angle. In the present embodiment, the support member 241 is positioned slightly above the lower end of the fixed plate 21, and the upper surface plate 2411 and the side surface plate 2412 projecting downward on both sides of the upper surface plate 2411. , 2413. The side plates 2412 and 2413 are extended to the rear side in the protruding direction of the support member 241, and the extended portions are welded and fixed to the side plates 22 and 23. The top plate 2411 and the side plates 2412 and 2413 are formed from a single plate by pressing.
The connection fitting 2b is inserted in the support hole 61 formed in the end face of the beam 6 in advance and the support member 241 and the support hole 61 are engaged with each other in the same manner as the connection fitting 2 described above. Are fixed to the beam 6.
And the connection metal fitting 2b and the receiving metal fitting 3 are joined in the procedure similar to the above-mentioned 1st embodiment.

As shown in FIG. 9, since the support member 241 is engaged with the support hole 61 in the beam 6, the beam 6 can be supported by the support member 241, and the beam 6 and the receiving metal fitting 3 are more firmly connected. Be joined. Therefore, the joint strength between the beam 6 and the column 5 can be improved.
In addition, since the beam 6 is supported by the support member 241 engaged with the support hole 61, compared to the case where the lower surface of the beam 6 is supported by the receiving plate 24 as in the above-described embodiment, the beam 6 is Even after contraction occurs, the beam 6 can be supported by the support member 241. Thereby, even if the beam 6 contracts, the bonding strength can be maintained substantially equal to the initial level of the bonding. Furthermore, since it can cope with the shrinkage of the beam 6, it is not necessary to use a sufficiently dried lumber for the beam 6, and a relatively inexpensive material can be used for the beam 6. The cost of the entire building used can be expected to be reduced.

As mentioned above, although the preferable embodiment was shown and demonstrated about the connection metal fitting, the receiving metal fitting, and the construction joining metal fitting of the present invention, the connection metal fitting, the receiving metal fitting, and the construction joining metal fitting concerning the present invention are limited only to the above-mentioned embodiment. It goes without saying that various modifications can be made within the scope of the present invention.
For example, the connection fitting 2 is fixed to the beam 6 by fastening the bolt 28 to the female screw 261 of the hiring fitting 26, but a male screw is formed instead of the female screw 261, and a nut is tightened instead of the bolt 28. It is good also as a structure to include.
Further, in the construction fitting 1, the connecting fitting 2 and the receiving fitting 3 are joined by the connecting pin 4, but a bolt and a nut may be used instead of the connecting pin 4.
Further, the hiring bracket 26 is not limited to the above structure, and may be a structure in which, for example, the upper surface of the beam 6 is embedded in the beam 6 and a female screw is cut at a position corresponding to the bolt 28.
