DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint between a column and a horizontal member, and more particularly, to a column and a base, a column and a beam, a bundle and a beam,
The present invention relates to a metal fitting between a column and a cross member suitable for use in a column and a connecting portion such as a pulling bar.

[0002]

2. Description of the Related Art In a wooden building, as shown in FIG. 11, vertical members such as a pillar 1 and a tubular column 2, a base 3, a beam 4,
A main part is assembled with a lateral member such as the waist 5 and a reinforcing member such as a blown fire 6 is inserted into a predetermined position to be firmly assembled.

[0003] These members are generally made of sawn wood cut from natural wood, and the vertical members such as the through pillar 1 and the tubular pillar 2 are arranged at a pitch of 910 mm or 1820 mm.

[0004] Further, at the connecting portion such as the pillar 1 and the base 3, for example, as shown in FIG. 12, a predetermined connection 7 is formed in each part, and further reinforced by a metal piece 8 or the like. As described above, in the frame of a conventional wooden building, in addition to the large number of columns, the connection between the vertical and horizontal members is troublesome and the number of parts is large at present.

On the other hand, in recent years, laminated wood or the like called engineer wood has been widely used because wood has been effectively used. According to such a laminated wood, it is possible to produce a large-section wood that was difficult to obtain with natural wood, and it is possible to provide a material having a uniform strength as a whole because of a small amount of moisture. I have.

[0006] Therefore, by using the laminated wood,
While the number of pipe columns 2 etc. can be reduced,
It has become easy to set a large space area for a room. By the way, when a house is constructed from such glued laminated lumber, in order to obtain a sufficient bonding force at the bonding portion, for example, FIG.
As shown in FIG. 3, there is a case where a metal joint using a hollow pipe is used. The metal fitting 11 includes a pipe 13 having a predetermined length with through holes 12 formed at both ends, and at least two metal members inserted into the through hole 12 of the pipe 13.
It consists of two rod-shaped members 14, and when used,
For example, as shown in FIG.
The lower hole corresponding to the diameter of the pipe 13 and a small hole orthogonal to the lower hole are opened from the side surface in the letter-shaped connection portion,
The base 3 and the column 1 are connected to each other by inserting a pipe 13 into the pilot hole and inserting the rod member 14 into the through hole 12 of the rod member 14 from an orthogonal small hole.

[0007]

However, in the case of connecting the column 1 and the base 3 by using such a connecting hardware 11, for example, the operation of forming a pilot hole of the pipe 13 in the column 1 and the base 3 is as follows. Although it is relatively easy to use a drill, there is a problem in that, when the pipe 13 is inserted as the next operation, the through-hole 12 must be arranged substantially toward the side surface, and there is a problem that it takes time to position the hole.

Further, the rod-shaped member 14 can be implanted only linearly with respect to the pipe 13, and there is a problem that the portion holding the pipe 13 is biased in a straight line. In view of the above-mentioned circumstances, the present invention can easily connect with a small number of parts even when connecting a column having a particularly large cross section, such as a glued laminated lumber, to a horizontal member, and furthermore, can average the strength of the connecting portion. It is an object of the present invention to provide a metal fitting for connecting a column and a horizontal member which can be held in a stable manner.

[0009]

According to the present invention, by using a flat metal body, it is possible to easily insert the metal body across the groove formed in the small end face of the pillar and the horizontal member. In addition, if the area of the metal body is increased, the number of the rod-shaped members can be increased in the width direction, such as two or in a staggered manner.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION In a metal joint according to the present invention, a metal main body is formed in a flat plate shape, and at least one through hole or two through holes, and further three staggered through holes are formed in the main body. Further, fine irregularities and the like are preferably formed on the peripheral surface of the rod-shaped member in order to increase friction.

On the other hand, in the vertical member and the horizontal member, a concave groove corresponding to a flat plate is formed in advance with a chain saw or the like. Accordingly, the metal body and the rod-shaped member can be easily inserted, and the strength of the joint can be increased.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a metal joint according to an embodiment of the present invention.

The metal joint 21 is composed of a metal body 22 in the shape of an oval flat plate and two bar-shaped members 23, 23.
These are all formed of metal. The diameter of the rod-shaped member 23 is the same as that of the through-hole 24 formed in the metal body 22.
It is formed slightly smaller than the diameter. Further, the rod-shaped member 2
On the peripheral surface of No. 3, irregularities 23a composed of fine lattice-like grooves are formed. These irregularities 23a may be formed on the entire peripheral surface, or may be formed only at both ends or one end, or even partially. Also,
Instead of the lattice-shaped grooves, the projections and depressions may be formed by columnar or quadrangular fine projections. In any case, it is preferable that a friction portion is formed on the peripheral surface of the rod 23.

Such a coupling hardware 21 is used, for example, as shown in FIG. FIG. 2 shows a structure of a connecting portion where a tube post 25 and a beam 26 intersect in a T-shape. here,
Both the tube post 25 and the beam 26 are formed from glued laminated wood and have a large cross section. In addition, the length of the beam 26 is long to form a large space, and has a heavy weight.

On the other hand, a groove 27 is formed in a vertical direction on a small end face 25a of a tube column 25 arranged vertically on a base (not shown) by, for example, a circular saw or a chain saw. Further, the tube column 2 is orthogonal to the concave groove 27.
A small hole 28 is formed to penetrate the side surface 5. On the other hand,
At the joint of the beam 26, a beam 26
A concave groove 29 is formed in the length direction. Further, a small hole 30 is formed through the concave groove 29 from the side surface. Note that the concave groove 29 may be a through hole. Here, the distal end shape of the concave groove 27 and the concave groove 29 opened by the chainsaw is formed in an arc shape, which is convenient for accommodating the metal body 22.

The metal body 22 is housed in, for example, a concave groove 27 formed in the tube post 25. The metal member main body 22 is supported by the rod-shaped member 23.

The pipe column 25 to which the metal body 22 is attached in advance in this manner also has its lower end similarly set up on a base (not shown). And a beam 2 as a horizontal member is provided at the upper end thereof.
6, the metal body 22 is inserted into the concave groove 29 of the beam 26.
Insert the upper end of. When the metal body 22 is securely inserted, the bar-shaped member 23 is inserted through the small hole 30 formed on the side surface of the beam 26.

When the rod-like member 23 is inserted, not only the load from the upper part but also the pull-out strength is exerted, so that it is possible to hold the rod securely as shown in FIG. Both can be combined without using any nails or the like.

In the above embodiment, the through hole 2 is
4 are formed one by one at the end, but these through holes 24
May be formed side by side as shown in FIG.
Alternatively, as shown in FIG. 5, the through holes 24 may be formed in a staggered manner. Thus, columns, beams, and the like having a larger cross section can be held at tightly dispersed positions. Further, the shape of the metal body 22 is not limited to a flat oval shape at all, and as shown in FIG. May be formed.

Further, in the above embodiment, the present invention is applied to the joint between the tube column 25 and the beam 26. For example, as shown in FIG. The present invention can be applied to a connection between another horizontal member and another vertical member such as a connection portion of a pipe column (or a communication column) 25, and a use location is not particularly limited.

As shown in FIG. 8, if one end of the rod-shaped member 35 is crushed so as to be slightly deformed, the crushed large-diameter portion 35a becomes an effective retaining member. It can be bonded more firmly. Further, as shown in FIG. 9, a spiral thread 36 is formed on the peripheral surface 36b of the rod-shaped member 36.
Even if c is formed, the effect of retaining is exhibited. In addition, such a thread 36c may be formed only at both ends or one end.

In FIG. 8, a large-diameter portion 35a which is crushed in the axial direction is formed at one end. However, as shown in the rod-shaped member 39 shown in FIG. Diameter 39
a can also be provided. Alternatively, it is also possible to use the rod-shaped member as the bolt 40 itself and tighten the nut 41 thereto.

According to each of the embodiments of the present invention, a heavy horizontal member or column member formed of a laminated material or the like can be easily connected to the other member. For this reason,
For example, the workability is good even when connecting a long member having a large weight and a long member. Moreover, for example, by arranging the rod-shaped members 35 in parallel or in a staggered manner, it is possible to maintain high strength with dispersed strength.

[0024]

As described above, according to the present invention, one side surface of a horizontal member such as a beam and a small end surface of a vertical member such as a tube pillar are connected by a simple metal member. Can be attached. In addition, the workability is good, and no trouble is required for the alignment and the like.

Further, by using this joint hardware, when a large space room is defined by glued laminated wood or the like,
