[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a pillar tenon used for connecting pillars and beams of a wooden house.

[0002]

2. Description of the Related Art In a conventional wooden house, a pillar and a beam are connected by forming a tenon with a saw or the like only at an upper end surface of the pillar, while a hole is formed only at a hole end at a pillar. The column and the beam are connected by inserting a tenon into the hole of this beam from above, or a hole is formed only on the side of the column, and the end of the beam is formed in this hole. The pillar and beam are connected by inserting a tenon tenon.

[0003]

However, when a hole is formed at the end of a beam or a hole is formed from a side surface of a column as described above, the amount of the column or the hole corresponding to the area of the hole is reduced. There is a problem that the strength of the beam is reduced. In addition, when a single-family wooden house is to be individually constructed, the traditional construction in which such pillars and beams are individually manufactured by hand is acceptable, but as in recent years a large number of houses of the same standard have been used to solve the labor shortage. In order to meet the demands for production, it is necessary to construct an efficient residential building by minimizing the labor of workers at the construction site as much as possible. For this reason, it has been desired to develop a construction method in which the connection between the column and the beam is also suitable for factory production. As a result of intensive research and development to respond to the demands of such an era, the applicant has developed a technology that can solve the above-mentioned problems.

[0004]

The cross groove provided on the end face of the pillar has a width substantially equal to the width of the cross groove, and
The column having a longitudinal length equal to the depth of the
Two with a lateral length of at least twice the width of
The center in the horizontal direction of the flat plate by half the width of the flat plate in the vertical direction.
The notch grooves formed by notching are fitted into each other
The mortise protrudes from the side surface of the end of the pillar by fitting the joining plate assembled in a cross shape.

[0005]

According to the above-mentioned means, it is only necessary to fit a joining plate combined in a cross shape into a cross-shaped groove formed on an end face of a pillar, so that a protruding tenon can be formed extremely easily. Then, the beam is rigidly fixed to the protruding tenon protruding from the side surface of the end of the pillar.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the projecting mortise 1 of the pillar in this embodiment is formed by fitting a joining plate 4 combined in a cross shape into a cross groove 3 provided on an end face of the pillar 2.

The width of the cross groove 3 is equal to or slightly smaller than the width of the joining plate 4 and its depth is equal to the length of the joining plate 4 in the vertical direction. If the width of the cross groove 3 is larger than the width of the column 2, the remaining members for supporting the joining plate 4 become smaller and the supporting strength is weakened, so that the width of the cross groove 3 is about 1 / the width of the column 2. 2
Or less is appropriate.

The joining plate 4 is formed by combining two flat plates 5 in a cross shape. As shown in FIG. 1, the center of the two flat plates 5 is notched in the vertical direction with the thickness of the flat plates 5. Notch grooves 6 are formed respectively, and the notch grooves 6 are fitted into each other to form a cross shape. Two flat plates 5
Is required to be at least about twice the width of the column 2.
By fitting the cross-shaped joining plate 4 thus formed into the cross groove 3, the joining plate 4 protrudes from the four side surfaces 7 of the column 2 to form the protruding tenon 1. At this time, the cross groove 3
The joint plate 4 can be sufficiently fixed by simply fitting the joint plate 4 into the column 2. However, if a wood-based adhesive or the like is used, the column 2 and the joint plate 4 are integrated.

[0009] The above is a tenon 1 for connecting the upper beam above the column 2.
Although the example in which the lower beam is provided has been described, the same applies to the case where the lower tenon 1 for connecting the lower beam is provided below the column 2 as shown in FIGS. 3 and 4.

The upper beam 8 is formed by using such a column tenon 1.
Will be described with reference to FIGS. 5 to 8. As shown in FIG. 6, the upper beam 8 joined to the column 2 is formed by connecting the upper plate 9 and the lower plate 10 to the vertical plate 11 above and below the vertical plate 11 with nails or an adhesive. The auxiliary plate 13 is a long member having a rectangular cross section in which at least the auxiliary plate 13 is fixed with a nail or an adhesive. When the auxiliary plate 13 is fixed to both sides of the vertical plate 11, the strength is further increased.

When the column 2 and the end of the upper beam 8 are joined using the column tenon 1 as described above, as shown in FIGS. Only vertical plate 11 of upper beam 8
Is formed short from its end, and a protruding portion 14 is provided in which the end of the upper surface plate 9 projects diagonally so as to be located at a diagonal line on the upper surface of the column 2. The end of the upper beam 8, which is shorter than the vertical plate 11, approaches the column 2 so that the protruding mortise 1 of the column 2 matches the vertical plate 11 of the upper beam 8. Then, at the same time, the projecting portion 1 of the upper plate 9 of the upper beam 8
4 rides on the upper surface of the pillar 2 and the lower plate 10 comes into contact with the lower surface of the protruding tenon 1. In this state, the two joining auxiliary plates 15 are protruded and nails or adhesives are attached to both sides of the tenon 1 and the vertical plate 11, respectively. Join with. By such joining, the mortise 1 and the vertical plate 11, the joining auxiliary plate 15 and the auxiliary plate 13 are respectively joined linearly, and the protruding portion 14 of the upper surface plate 9 rides on the upper surface of the column 2, and furthermore, Then, the upper plate 9 rides on the protruding tenon 1 so that the joint between the column 2 and the upper beam 8 becomes firm.

As described above, another method of connecting the protruding tenon 1 and the upper beam 8 may be used, for example, the protruding tenon 1 and the end of the upper beam 8 may be connected by nailing or the like. It is not limited to the construction method. The tenon 1 protrudes from the four side surfaces 7 of the pillar 2, but the unused tenon 1 may be cut off. In general, a wooden joint plate 4 is used for the pillar 2 of a wooden house, but a synthetic resin or a metal material can also be used.

[0013]

[Effects of the invention] As is clear from the above description, the pillar of the present invention is formed by projecting from the side of the end of the pillar. As a result, it is possible to adopt a connection method different from the conventional connection of columns and beams without reducing the strength of columns and beams, for example, for mass production in factory production There are advantages such as that a suitable house can be manufactured.
