DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for construction, and more particularly, to an improvement of a metal fitting used for connecting a column to a beam or a body.

[0002]

2. Description of the Related Art Conventionally, when a column and a beam are joined, for example, a tenon 27 provided on a joint surface of a beam 16a is fitted into a tenon 28 provided on a column 21a as shown in FIG. Attaching and fixing the U-shaped box hardware 29 from the back side of the 21a,
The two members are joined by fixing the blade bolt 30 to the column 21a so as to receive the beam 16a.

[0003]

However, in the above-mentioned conventional apparatus, it is premised that the tenon 27 of the beam 16a is fitted into the tenon 28 of the column 21a, so that the beam 16a is always provided with a tenon 27 of a special shape. However, the fabrication of the beam 16a becomes very troublesome, and the fabrication cost is greatly increased.

Further, in order to reinforce such a tenon joint, two types of construction metal fittings, that is, a box metal fitting 29 and a wing plate bolt 30 are used, so that the number of parts is large, so that the work in actual construction is complicated. There was also the inconvenience of becoming.

In addition, several kinds of box fittings 29 and vane plate bolts 30 having different dimensions according to the size of the beams 16a and the columns 21a to be joined must be prepared, and their parts management is very troublesome. Was.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned conventional problems, and provides an architectural fitting which can easily perform a joining work of columns and beams. And to contribute to the efficiency of

[0007]

Means for solving the above problems, ie, means adopted by the present invention for solving the above problems are a first joint fitting A which is fitted in advance in a tenon 22 provided in one piece of wood 21 and the other, and And a second joint fitting B fixed in advance to the end face of the wood 16 to join the end face of the other wood 16 to the one wood 21.
The first joint A is provided with an engaging means capable of engaging and holding the second joint B.

[0008] Therefore, when using the architectural joints characterized by the above-mentioned specific features of the invention, the joints A and B must be prepared in advance.
Is fixed to each of the timbers 22 and 16, and the second joint B is connected to the first
If the engagement is held by the engagement means of the joining fitting A, the end face of the other wood 16 can be joined to the one wood 21.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a construction metal fitting according to the present invention.

In FIG. 1, reference numeral 1 denotes a band-shaped metal fitting body in which two long holes 2 are formed at predetermined intervals above and below, and a pair of opposing side pieces 3 project from the front surface thereof. Each side piece 3 is provided with a pair of locking recesses 4 that are narrower toward the lower end and are displaced back and forth. Reference numeral 5 denotes a top plate protruding from the upper end side of the bracket main body 1, and a screw hole 6 is formed in the center thereof. Reference numeral 7 denotes a mounting plate fixed to the lower end surface of both side pieces 3, and the front end thereof is formed in a semicircular shape. The first joining fitting A is configured as described above.

In FIG. 2, reference numeral 8 denotes a top plate 10 having an elongated hole 9 formed at the upper end thereof, a top plate 10 formed by bending forward, and a fixing piece 13 projecting in the center of the back surface along the longitudinal direction. In the bracket body,
A pair of opposing side pieces 11 protrude from the front surface,
Each side piece 11 is provided with a pair of locking recesses 12 in which the locking pieces 4 of the first metal fitting A are engaged with each other in front and rear directions. However, through holes 15 are formed at the lower end side. The second joint fitting B is configured as described above.

The second joint B is used by being fixed to the joint end face of the beam 16 as shown in FIG. 3, for example. Such beams 16
A mounting groove 17 is provided in the center of the joining end surface of the first and second mounting brackets 17, and a cut groove 18 is formed in the center of the mounting groove 17, and the fixing piece 13 of the second bonding bracket B is inserted into the cut groove 18. Then, an insertion hole (not shown) formed in the beam 16, a long hole 14 and a through hole 15 of the fixing piece 13 are provided.
Then, the nut 20 is fastened by inserting the long screw 19. As a result, the top plate 10 of the second metal fitting B and the front surface of each side piece 11
Is set flush with the joining end face of

On the other hand, as shown in FIG. 4, for example, as shown in FIG. 4, a first joint fitting A has a fitting main body 1 inserted into a mortise hole 22 recessed in the side surface of a pillar 21 and an insertion hole formed in the elongated hole 2 and the tenon hole 22. The nut 25 is tightened by inserting the long screw 24 into the hole 23.

Next, the beam 16 is joined to the column 21.
In this case, when the locking piece 4 of the first metal fitting A is engaged with the locking recess 12 of the second metal fitting B as shown in FIG. The beam 16 is attached to the side surface of the column 21 while the beam 16 is placed on the mounting piece 7 of the first fitting A while the top plate 10 of the second fitting B abuts on the top plate 10 of the second fitting B. .

After that, the bolt 26 is connected to the top plate of the second fitting B.
If the beam 16 is inserted into the elongated hole 9 provided on the top 10 and screwed and fixed to the screw hole 6 provided on the top plate 5 of the first fitting A, the beam 16 is securely and firmly joined to the column 21 without being lifted. be able to.

The first and second joints A and B can be attached to the columns 21 and the beams 16 in a factory or the like, and the attachment can be performed very easily. it can.

[0017] Further, by carrying in such a form to the site, the joining operation at the site can be simplified, which can greatly contribute to shortening the construction period.

Further, the architectural joint according to the present embodiment has an advantage that it can be widely applied to beams 16 and columns 21 having different dimensions.

Further, since the architectural joint according to this embodiment has a simple structure, it has an advantage that it can be manufactured easily and at low cost.

Note that the first joint B is engaged with the first
The engaging means provided on the joining fitting A is not limited to the one in the above embodiment, and the specific means is not limited.

In the above embodiment, the top plates 5 and 10 are provided on each of the joining fittings A and B, and
Although fixed by 26, the top plates 5 and 10 may be provided as needed.

Further, in the above-described embodiment, the fixing piece 13 protrudes from the back surface of the fitting main body 8 in order to fix the second joining fitting B to the end face of the beam 16, but such fixing means is not limited to this. Not something.

In consideration of the stability of the beam 16, the first
It is preferable that the mounting plate 7 be provided with the mounting plate 7 as in the above embodiment, but this may be omitted.

Further, the wooden members to be joined in the present invention are not limited to the beams 16 and the columns 21 and can be applied to the case of joining other members such as a body difference.

[0025]

As described above, the present invention is different from the conventional method in which the mortise and the tenon are fitted to each other on the premise that the mortise and the tenon are fitted to each other. In order to join the two woods by engaging and holding the joining metal fittings, work on site is greatly simplified,
The special effect that the construction period can be greatly shortened has been obtained.

Further, as described above, since the architectural joint according to the present invention has a very simple structure, there is also a practical effect that it can be manufactured easily and at low cost.
