DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column joint for joining a column to a horizontal member.

[0002]

2. Description of the Related Art In a wooden house, when a pillar is joined to a horizontal member such as a base or a beam, it is important from the viewpoint of earthquake resistance to enhance the joining strength by reinforcing them with reinforcing hardware.

[0003] As such reinforcing hardware, various shapes such as triangular, T-shaped, strip-shaped and mountain-shaped are commercially available, and a triangular reinforcing metal is shown in FIG. 4 (a) as an example. . As can be seen from the figure, the triangular reinforcing metal member 1 is composed of a joint plate applied to the joint boundary between the column 2 and the base 4 which is a horizontal member, and is applied to the side surface of the column 2 of the joint plate. Insertion holes are formed in the column-side abutting portion and the cross member-side abutting portion applied to the side surface of the base 4, respectively. Then, by inserting a screw nail or the like into the insertion hole and driving it in, the column 2 can be firmly joined to the base 4.

Here, in the case of a three-story house, a through pillar may need to be 120 cm square in some cases due to the standards set by the loan institution.
To use 105cm square wood, their sides are
A step of 7.5 mm occurs on both sides.
Therefore, when attaching the reinforcing metal 1, the side surface of the pillar 5 is dug into a depth of 7.5 mm using a chisel or the like as shown in FIG. The part had to be fitted and nailed.

[0005]

However, it is troublesome to dig the pillars 5 one by one according to the shape of the reinforcing metal piece 1, and there is a problem that it is necessary to consider the cross-sectional defect due to the digging. I was

On the other hand, when the reinforcing hardware 1 is attached without performing such dug-out, the metal fitting looks like straddling a step and a gap is formed between the metal base 1 and the base 4. Is insufficient, and the original bonding strength may not be secured.

The present invention has been made in consideration of the above-described circumstances, and has a column that can be easily attached while ensuring a sufficient joining strength when a step is generated between the column and the horizontal member. It is intended to provide a connector.

[0008]

According to a first aspect of the present invention, there is provided a column joining device comprising a joining plate applied to a joining boundary between a column and a lateral member. Of the joining plate, insertion holes for inserting nails and the like were formed in the column-side abutting portion applied to the side surface of the column and the cross member-side abutting portion applied to the side surface of the horizontal member, respectively. In the column connector, a step is formed in the bonding plate, and one side of the step is the column contact portion and the other side is the cross member contact portion.

Further, in the column connector according to the present invention, the step is provided with a reinforcing rib.

In the column connector of the present invention, the column-side abutting portion is applied to the side surface of the column, and the horizontal member-side abutting portion is applied to the side surface of the horizontal member. In this state, a nail or the like is inserted into the insertion hole. It is inserted and driven or screwed into the pillar and the horizontal member.

[0011] In this case, the step formed between the column and the horizontal member is absorbed by the step formed on the joining plate, and the joining plate is connected to the column at the column-side contact portion. It is applied exactly to the side, and is applied exactly to the side of the cross member at the cross member side contact part.

Therefore, there is no possibility that a gap is formed between the column-side abutting portion and the column and between the horizontal member-side abutting portion and the horizontal member, and a sufficient bonding strength is secured.

Here, when the reinforcing rib is provided on the step, the rigidity against the pull-out force of the column is improved, so that the thickness of the joining plate can be reduced.

[0014]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a column connector according to an embodiment of the present invention. It is to be noted that the same reference numerals are given to components and the like that are substantially the same as those in the conventional technology, and description thereof will be omitted.

FIG. 1 is an overall perspective view showing a pillar connector 11 according to the present embodiment, FIG. 2 is a front view and a side view of the same, and FIG. It is the whole perspective view which shows a state.

As can be seen from these figures, the column connector 11 of the present embodiment forms a step 13 at the boundary between the triangular portion and the square portion on the bonding plate 12 having a front shape connecting the triangle and the square. The triangular portion is a column-side contact portion 14, the square portion is a cross member-side contact portion 15, and a nail or the like is inserted into the column-side contact portion 14 and the horizontal member-side contact portion 15. Insertion holes 16 and 17 are formed.

The joining plate 12 is made of, for example, a steel plate having a thickness of about 2 to 3 mm, and can be bent to form a step 13. The height of the step 13 is の of the dimensional difference between the column 5 and the base 4. For example, the width of the column 5 is 120 m.
m and the width of the base 4 is 105 mm, the height is about 7.
It may be 5 mm.

The step 13 is provided with a reinforcing rib 20 to increase the rigidity in the tensile direction, so that when a pulling force acts on the column 5 during an earthquake, the pulling force can be transmitted to the base 4. I have.

An engaging claw 18 is formed at the tip of the column-side abutting portion 14 by bending the same, and similarly, at both corners of the cross member-side abutting portion 15, they are attached. The engagement claws 19 are formed by bending.

In order to join the column 5 to the base 4 using the column connector 11 of this embodiment, first, as can be clearly seen in FIG. To the side of the pillar 5 and the side of the base 4, respectively.
The step 13 is applied to the lower end cut of the pillar 5 to perform vertical positioning.

Next, after the positioning in the horizontal direction is appropriately performed, the engaging claws 18 and 19 are driven into the side surfaces of the column 5 and the base 4 to temporarily fix the column connector 11. And finally, for example, a screw nail is inserted through the insertion holes 16 and 17,
The nail is driven into the pillar 5 and the base 4.

In this case, the step of 7.5 mm generated between the column 5 and the base 4 is absorbed by the step 13 formed on the joining plate 12, and the column-side contact portion 1
4. The horizontal member-side abutting portion 15 is fitted to the side surface of the pillar 5 and the side surface of the base 4, respectively.

As described above, according to the column connector 11 of the present embodiment, the step 13 formed on the joint plate 12 is formed.
Thereby, the step between the pillar 5 and the base 4 is absorbed. Accordingly, there is no possibility that a gap is formed between the column-side contact portion 14 and the column 5 and between the horizontal member-side contact portion 15 and the base 4, and it is possible to secure sufficient joint strength.

Further, when mounting, it is not necessary to dig the column 5 to the depth corresponding to the step between the column 5 and the base 4 as in the conventional case. It is sufficient if it is applied and fixed with a screw nail or the like. Rather, by attaching the step 13 of the joining plate 12 to the lower end of the column 5, the positioning in the vertical direction can be performed, so that the mounting becomes easier than the ordinary triangular plate. And by such improvement of workability, there is no possibility that improper work such as mounting over a step without performing digging is performed.

Further, since the reinforcing ribs 20 are provided on the steps 13, the rigidity against the pull-out force of the columns 5 is improved, and the thickness of the joining plate 12 can be made smaller than when no reinforcing ribs are formed.

In the present embodiment, the reinforcing rib 20
Is provided, but this may be omitted if a predetermined tensile rigidity can be secured by increasing the plate thickness. Further, the position of the reinforcing rib is not limited to the center of the joining plate as in the embodiment, but may be formed at both ends of the step, for example.

In this embodiment, the engagement claws are provided at the tip of the column-side contact portion and at both corners of the horizontal member-side contact portion. However, the step formed on the joining plate facilitates positioning. As a result, if the temporary fixing becomes unnecessary, it may be omitted.

Further, in this embodiment, the case where the pillar is joined to the base at the lower end has been described. However, the horizontal member referred to in the present invention includes not only the base but also a beam and a trunk. It goes without saying that the column connector of the present invention can also be used for joining to a beam at the upper end of a column, for example.

[0029]

As described above, the column joint of the present invention comprises a joint plate applied to a joint boundary between a column and a horizontal member, and is applied to a side surface of the column in the joint plate. In a column connector having an insertion hole for inserting a nail or the like into a column-side abutting portion and a horizontal-member-side abutting portion applied to a side surface of the horizontal member, a step is formed in the bonding plate. ,
Since one side of the step is the column-side contact portion and the other side is the cross member-side contact portion, sufficient joint strength can be obtained when a step is generated between the column and the cross member. Mounting can be easily performed while securing the height.
