Description

Detailed Description of the Invention

[0001]

The present invention relates to a wooden construction method.

[0002]

2. Description of the Related Art In Japanese Patent Publication No. 55-6133, a foundation and a joist are erected on a foundation, and the first floor is entirely covered with a floor.
Next, pillars, beams, and girders are erected to assemble the first-floor frame, and joists are erected on the first-floor beams and girders through a metal fitting so as to be flush with the beams and girders. A timber construction method has been proposed in which the entire floor is stretched, and then columns, beams and girders are erected to assemble a two-story frame, and a roofing material is erected above the frame.

This construction method can reduce the cost of construction work and shorten the construction period, and can improve the quality of houses.

[0004]

However, when compared with the conventional wooden frame construction method, this method is easier to install because it does not use through columns, and it is necessary to use a long material as a column material. Although there are advantages such as not being provided, the use of the stools and the installation of the joists by attaching the small beams or the large pulleys on the first floor require labor and time for mounting the stools, which has the disadvantage of increasing the cost.

[0005] Further, since a stud supported by a runner and a head joint is erected on the floor surface and a base material is attached, the material volume is increased, and an increase in cost due to this is inevitable.

[0006]

The base 2 is fitted into the notch 22 and is fixed by nailing from the surface of the structural plate 19. In addition, the reinforcing bar 20 is fixed and reinforced with respect to the base 2 and the first-floor pillar 10 by using a metal fitting such as a short metal fitting or an L-shaped metal fitting.

Although the reinforcing bar 20 is shown as one vertical bar in the configuration example of FIG. 14, it may be formed as a horizontal bar.
Both vertical and horizontal rails may be provided. Further, a plurality of reinforcing bars 20 can be provided if necessary.

FIG. 15 shows another structural example of the outer wall panel 18, in which a piece member 23 having an arbitrary length is attached to both ends of the reinforcing bar 20. The piece member 23 is provided so as to be flush with the ostium surface of the heat insulating material 21, and a nail 2, a screw, or a screw is screwed from the piece member 23 to the base 2, the pillars 10 and 14, which are fitted to the cutout portion 22, and the horizontal bridge. The materials 11 and 15 can be fixed and reinforced.

The outer wall panel 18 is built between the first floor pillars 10 so that the notch 22 on the back surface of the structural plate 19 contacts the base 2 and the first floor pillars 10, and nailed to the first floor pillars 10 on one side. And temporarily fix it. Since the first-floor pillar 10 is fitted in the notch 9 of the first-floor floor panel 5 and is built on the base 2 by a joint, the pillar interval can be adjusted, and the outer wall panel 18 can be built.
