Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame between a base and a roof of a wooden building, and more particularly to a frame in which a vertically long piece of wood such as a pillar and a horizontally long piece of wood such as a bobbin cross in a cross shape. The present invention relates to a reinforcing metal fitting for reinforcing steel.

[0002]

2. Description of the Related Art Conventionally, when a building is shaken by a typhoon, a tornado, an earthquake, etc., a concentrated load is applied to an intersection of a framing, and the intersection is prevented from coming off or being damaged. It is known to use hardware.

[0003]

However, the conventional reinforcing bracket is one that strikes a simple clamp at the intersection of two timbers,
Alternatively, as shown in Japanese Utility Model Laid-Open Publication No. 53-97508, a beam support having a U-shaped cross section is provided on both sides of a pillar having a rectangular cross section for inserting the end of the pillar. There is also known one provided with a staff at the intersection of a girder and a girder.

[0004] However, in the former case, it is difficult to mount in the correct position.
Not only was it difficult to sufficiently exert the function as the reinforcing bracket, for example, because it was mounted in a shifted state, but also the reinforcement was not sufficient.

In the latter case, the column and the girder can be connected, but this is simply the case where the column is inserted into the column and the girder is inserted into the girder and nailed. It only functions as a joint fitting for joining with a pillar.Moreover, it is composed of a pillar with a square cross section and a girder mounting with a U-shaped cross section. There is a problem that there is.

[0006] It is an object of the present invention to provide a reinforcing fitting free of such a problem.

[0007]

According to the first aspect of the present invention, in order to achieve the above object, there is provided a timber that is disposed in a trunk and other horizontal directions, and a timber that is disposed in a side pillar and other vertical directions. In the frame provided with the crossing portion where the wood to be crossed intersects in a cross shape, the outer surface of the wood that crosses in a cross shape and the outer surface of the four narrow angles formed between the intersecting woods are covered. The reinforcing fitting includes a square bracing portion and a holding portion protruding from each of four corners of the bracing portion along each piece of wood, and a portion of the bracing portion along the outer surface of each piece of wood. Characterized in that the holding portion is configured to be bound to the wood by a binding means such as a nail, and the width of the reinforcing bracket is substantially equal to the interval between the columns constituting the shaft assembly. When the frame rolls and pitches due to an earthquake or the like, the horizontal timber and the vertical timber intersect in a cross shape. The concentrated load applied to the intersection coupling of wood together to assemble the reinforcing bracket with reinforcing brackets will bear becomes strong, thereby particularly formed in the crossing portion 4
Since each of the narrowed portions can be reinforced by one common reinforcing bracket, it is extremely robust.

[0008] By making the length of the bottom side of the reinforcing bracket substantially equal to the length between the columns constituting the shaft assembly, which is not seen in the conventional example, the strength of the entire frame assembly is increased, and it is resistant to shaking. House can be provided.

The reinforcing metal fitting is applied to the intersection where the horizontally long wood and the vertically long wood cross in a cross shape, and the abutting portion formed by bending both edges of the protruding portion sandwiches the horizontally long wood and the vertically long wood. Can be easily positioned, and a binding operation such as nailing can be easily performed.

In addition, since the protruding portion is provided along each piece of wood, a load which tends to concentrate on the end of the reinforcing metal can be dispersed to the protruding portion, and the outer surface of each piece of wood at the bracing portion is provided. Since the portion along the holding portion and the holding portion are bonded to the wood by a bonding means such as a nail, a widened bonding portion between the reinforcing metal and the wood by the bonding means such as a nail can be obtained.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a reinforcing member made of an aluminum plate, a brass plate, a steel plate, or other metal plate. It reinforces the crossing portion where the side pillars and other wood B (square lumber) arranged in the vertical direction cross in a cross shape, and the outer surfaces of the woods A and B crossing in a cross shape and the wood crossing in the cross shape A square bracing portion 2 covering the outer surfaces of the four narrowed portions X formed between A and B, and protrudes along the respective woods A and B from the four corners of the bracing portion 2. The reinforcing metal fitting 1 is provided with the protruding holding parts 3 and 4, and the width of the reinforcing metal fitting 1 is made substantially equal to the interval between the side pillars and other woods B arranged in the vertical direction that constitute the shaft assembly. The portions of the intersection 2 along the outer surfaces of the woods A and B and the side surfaces of the holding portions 3 and 4 are bonded to the woods A and B by a bonding means such as a nail.

The holding portion 3 is formed by a protruding portion 5 protruding along the outer surface of the wood A and bent portions 6, 6 formed by bending both sides of the protruding portion 5 along the upper and lower surfaces of the wood A. And the holding portion 4
A protruding portion 7 protruding along the outer surface of the wood B;
8 and 8 bent along both sides of wood B
And formed.

In this manner, the reinforcing member 1 can be easily and reliably attached to the correct position of the intersection of the woods A and B by the holding portions 3 and 4.

[0015]

According to the first aspect of the present invention, when the frame is swayed and swayed due to an earthquake or the like, the reinforcing member for the frame is used at an intersection where the horizontally long wood and the vertically long wood cross in a cross shape. This concentrated load is borne by the reinforcing metal and the connection of the wood pieces to be assembled by the reinforcing metal is strengthened. In particular, the four narrowed corners formed at the intersection can be reinforced by one common reinforcing metal. Extremely robust.

[0016] By making the length of the bottom of the reinforcing bracket substantially equal to the length between the columns constituting the frame, which is not seen in the conventional example, the strength of the entire frame is increased to be resistant to shaking. House can be provided.

The reinforcing metal fitting is applied to the intersection where the horizontally elongated wood and the vertically elongated wood cross in a cross shape, and the horizontally elongated wood and the vertically elongated wood are sandwiched by the sandwiching portion formed by bending both edges of the protruding portion. Thus, positioning can be easily and reliably performed, and a binding operation such as nailing can be easily performed.

Further, since the protruding portion is provided along each of the timbers, a load which tends to concentrate on the end of the reinforcing metal can be dispersed to the protruding portions, and the outer surface of each of the timbers at the bracing portion is provided. Since the portion along the holding portion and the holding portion are bonded to the wood with a bonding means such as a nail, the bonding portion of the reinforcing metal and the wood with the bonding means such as a nail can be widened, and the reinforcing metal can be connected to a horizontally long piece of wood. Can be firmly connected to the intersection where the timber crosses vertically.
