Hereinafter, this configuration will be described in detail.

FIG. 2 shows an arrangement for connecting two laterally arranged timber beams 2, 3 arranged at right angles. In the figure, an end 20 of one laterally arranged timber beam 2 has an upper portion 21 and a lower portion 22.
And a step portion 23 is provided between them, and the upper portion 21 projects outward with respect to the lower portion 22. A small groove 24 is provided between the upper part 21 and the lower part 22 so as to be continuous with the step part 23.

A joint fitting 25 is provided on an end face of the upper portion 21. The joint fitting 25 includes a flat plate portion 26 having a width C smaller than the width B of the laterally arranged timber beam 2, a load receiving portion 27 provided at an upper end thereof, another load receiving portion 28 provided at a lower end thereof, and a tip of the load receiving portion 27. It consists of two claws 29, 29 '. The load receiving portion 27 extends in the direction of another laterally arranged timber beam 3, and the other load receiving portion 28 is inserted and disposed in the groove 24. The claws 29, 29 ′ have a tapered portion 30 formed in the direction of the laterally arranged timber beam 2. Other load receiving part 28
Is placed on the bottom surface 37 of the groove 33.

The joint fitting 25 thus constructed
Is disposed on the end face of the upper portion 21 of the laterally arranged timber beam 2 by screws (not shown) via the screw holes 31 and 31 'so as to face the other laterally arranged timber beam 3.

The connecting portion 32 of the other laterally arranged timber beam 3 to which the laterally arranged timber beam 2 is connected has a side groove 33 on the side surface thereof.
The upper surface groove 34 is continuously formed in the upper surface portion.

Therefore, the contact surfaces 35 and 36 are formed in the connecting portion 32 in a concave shape.

FIG. 3 shows a part configuration before the joint fitting 25 is formed, and a flat plate (base) 41 forming the flat plate portion 26, left and right bent shapes (overhang, underhang) 42, 43, and a bent shape 42. Two claws 29,2 integrated by welding
The flat plate 41 and the bending members 42, 43 are integrated by joining (welding) 45, 46, respectively. The claws 29, 29 'are also integrated with the bending member 42 by welding. The advantage of using the bending members 42, 43 is that the bending members 42, 43 are approximately 90 ° at their center.
Not only does it not have to be bent in advance and need to be bent again, but also the use of simple flat plate bending does not result in bulging bending. As a result, full contact is immediately possible. Of course, it may be made from one flat plate. Alternatively, it may be prepared by pouring a molten iron material into a mold.

The two beams 2 and 3 are connected as shown in FIG. 4 using the joint fitting thus constructed. FIG.
As shown in (a), the laterally-arranged timber beam 2 approaches the other laterally-arranged timber beam 3 to bring the flat plate portion 26 and the load receiving portion 27 into contact with the contact surfaces 35 and 36, and the claws 29 to the contact surface 36. Drive in. At this time, the tapered portion 30 functions to draw the beams 2 and 3 mutually. Instead of the tapered portion, other pulling structures can be adopted.

In this case, the flat plate portion 26 of the fitting 25 is accommodated in the side groove 33, and the load receiving portion 27 is accommodated in the upper groove 34. It is appropriate that the groove depth of the groove portions 33 and 34 be the plate thickness of the flat plate portion 26 and the load receiving portion 27.

By doing so, FIG.
Is completed. As a result, the load of the laterally-arranged timber beam 2 is supported by the other laterally-arranged timber beam 3 at two places of the load receiving portions 27 and 28 in a state where both are attracted to the other laterally-arranged timber beam 3. . In addition, both timber beams can be tied using a conventional shingle board.

In the case of this example, the processing applied to the laterally arranged timber beam 2 is the step 23 and the groove 24, and the degree of processing can be suppressed to a small level. Further, it is sufficient to form a groove having only the thickness of the flat plate portion in the other laterally arranged timber beam 3. As a result, the flat plate portion 26 and the other load receiving portions 28 are hidden in both beams, and only the load receiving portions 27 are exposed to the outside. Therefore, when viewed from the lower side, it looks the same as the conventional groove fitting structure and is beautiful. Also, the load receiver is a load receiver 27, 2
8, and a large holding force can be obtained.

FIG. 11 shows an example in which a flat metal part 61 is embedded in a groove 71 provided in a vertically arranged timber beam (through column) 5.
Other configurations are the same as those in FIG. Thus, when the receiving metal part 61 is mounted on the flat metal part 53, the flat metal part 53
Can be completely hidden from the outside.

As described above, according to this example, it is sufficient to form the groove 51 in the laterally arranged timber beam 4. In addition, bending part 5
When 5 is not used, the groove 52 need not be formed.
Further, it is sufficient to form the holes 68 and 69 in the vertically arranged timber beam 5, and even in the example of FIG. 11, it is sufficient to form the groove 71 having a flat plate thickness, and the amount to be processed is extremely small. .
In this manner, the load of the horizontally arranged timber beam 4 is applied to the vertically arranged timber beam 5 in a state where the pawl 65 draws the two arranged timber beams 4 and 5 together with the mounting of the receiving metal part 61 on the flat plate portion 54.
Can receive. Moreover, in this case, the flat plate portion 5
4. Both of the other flat portions 62 are made of the same width C, so that they are hidden between the timber beams 4 and 5 arranged so that they can hardly be seen from the outside and keep the beauty of the wood. Yes, high commercial value.

In terms of strength, compared to the conventional construction method (wood ant processing), the present invention is designed so that it can be hooked and mounted, so that the load bearing capacity of a pine 120 × 240 mm wood frame is 6.4.
Ton is 10.4 ton. Sufficient load capacity without weakening the wood.

Further, the present invention can be applied to general wood, regardless of the laminated wood.

[0051]

As described above, according to the present invention, the joint fitting having a width within the width of the horizontally arranged timber beam and the vertically arranged timber beam is used. The timber retains its beauty and can support the load with a simple hook without weakening the timber, so that the load resistance of the timber does not deteriorate. In addition, due to the function of the taper provided on the claw when attached, the two beams placed on each other receive and receive the load attracted to each other, and even if there is a vibration such as an earthquake due to the function of the claw, the load receiving beam provided on the beam Despite the simple configuration, security is maintained without deviating. As described above, according to this structure, even an unskilled person can easily and quickly connect the arranged timber beams securely. With the same design, there is versatility because it can be used at any connection point. Therefore, workability is good and management is easy.

In addition, since the protrusion of the metal fitting is small when the wood is carried into the site, a large amount of the wood can be loaded on the truck.
