Abstract

PURPOSE:To facilitate construction and to gain high constructive strength by respectively forming female tenons on a column material and a first beam material, forming a male tenon on a second beam material against it and fitting this male tenon in both of the female tenons. CONSTITUTION:A first female tenon 3 is cut and formed on a standard face 1 of a column material A. Thereafter, on a standard face 5 of a second beam material C, a male tenon 6 is cut and formed. After the first beam material B is jointed to an upper part of the column material A, the second beam material C is dropped. Consequently, it is possible to integrally joint the three members without using a metal fitting and others and to extensively reduce construction labour and cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tenon structure for wooden construction materials used at a position where three members intersect.

[0002]

2. Description of the Related Art A conventional construction method is called a shaft assembly method, and male and female tenons are formed on a structural member, and they are assembled by fitting them. In this construction method, there are locations where three or more members intersect and are joined. That is, as shown in the example of FIG. 3, in the case where the first beam member B is joined to the upper end of the pillar member A and the second beam member C is joined to both members A and B so as to be orthogonal to each other. Is that.

In the above joining, a male tenon a is formed on the upper end of the beam A as shown in FIG. 4, and this male tenon a is fitted to the female tenon b1 on the lower surface of the first beam B. Further, a female tenon b2 is formed on the side surface of the first beam B, and the male tenon c of the end face of the second beam C is fitted into this female tenon b2.

[0004]

SUMMARY OF THE INVENTION In the above cases,
Height dimension (thickness) of the second beam member C with respect to the first beam member B
When is the same or small, there is no special problem. But,
When the relationship between the two is reversed and a large gap is generated, the second beam C is separated from the column A on the lower end side thereof. Here, in the related art, the second beam member C and the column member A are connected by the metal fitting D, and the both are connected by the nail E.

Therefore, in this case, there arises a problem that extra cost and labor are required for construction. Further, there is a problem that the joining by the metal fitting D has a limit and a sufficient structural strength cannot be obtained. The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a tenon structure of a wooden construction material that is easy to construct and has high structural strength.

[0006]

In order to achieve the above object, the tenon structure according to the present invention is as follows. That is, the gist thereof is that when the first beam member is joined to the column member and the second beam member is joined so as to be orthogonal to the column member and the first beam member,
Female mortises were formed on the column member and the first column member respectively, while male tenons were formed on the second beam member, and the male mortises were fitted to both female mortises. Especially.

[0007]

The male tenon formed on the second beam member simultaneously fits the female tenon of the first beam member and the female tenon of the column member, so that the three members can be integrally connected. Therefore, no special metal fitting is required. Also, a large structural strength can be obtained.

[0008]

EXAMPLE A tenon structure according to the present invention will be specifically described with reference to examples. It should be noted that, in the following, the same members and parts as those in the conventional structure are shown with the same reference numerals, and duplicate explanations are omitted. FIG. 1 is an exploded perspective view showing the tenon structure, and FIG. 2 is a vertical sectional view of the same.

In the figure, reference numeral 1 is a reference surface formed by cutting one side surface of a pillar material A. This reference surface 1 is provided at a position of a constant dimension H from the center line of the pillar material A as a reference. Reference numeral 2 is a reference surface formed on one side surface of the first beam member B, and this reference surface 2 coincides with the reference surface 1 of the above-mentioned pillar material A. This reference plane 2
Is a constant dimension J from the center line of the beam B as a reference.
It is installed at the position.

Reference numeral 3 denotes a first female tenon machined in the pillar material A so as to open in the reference plane 1, and 4 denotes a second female tenon machined in the first beam material B so as to open in the reference plane 2. The above-mentioned first and second female mortises 3 and 4 have the same cross-sectional shape (large dovetail mortise) when viewed from above, and when the pillar material A and the first beam material B are combined, Continuous in the direction.

The above-mentioned first and second female tenons 3 and 4 are the first
The depth dimension is set with reference to the upper surface of the beam B. Next, 5 is a reference surface 6 formed on the end surface of the second beam C. 6 is a male tenon machined so as to project from the reference surface 5, and this male tenon 6 is the above-mentioned first and second female It has a cross-sectional shape that fits tightly into the tenons 3 and 4. The depth of the male tenon 6 is set with the upper surface of the second beam C as a reference.

The construction of the tenon structure according to one embodiment is as described above. Therefore, if the second beam member C is dropped from above the first beam member B after connecting the first beam member B to the upper part of the pillar member A, the male tenon 6 of the beam member C is common to both female tenons 3 and 4. And the three members can be integrally connected.

The procedure is changed so that the pillar material A is replaced with the second pillar material C.
Even if the first beam member B is dropped from above the pillar member A after the tenon is fitted, the three members can be integrally connected in the same manner as described above. In the above, especially the second beam C
Since the lower side is connected to the pillar material A, it is possible to omit the labor of connecting with a metal fitting as in the conventional case.

In the above embodiment, the tenon structure is shown in which the first beam member B is erected on the column member A, but the column member A is erected on the first beam member B. The present invention can also be applied to such cases. Although the female mortises 3 and 4 are continuous in the vertical direction, they may be divided into a pillar material A and a beam material B. In this case, the second beam C is provided with male tenons individually.

[0015]

As described above, according to the tenon structure according to the present invention, it is possible to integrally join structural members including at least three members without using metal fittings or the like. Therefore, it exerts an excellent effect that the labor and cost of construction can be significantly reduced. Also, a large structural strength can be obtained by integrally connecting the three members.
