DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition structure between wooden buildings, that is, between the first and second floors or between the second and third floors.

[0002]

2. Description of the Related Art A joist is erected on a beam and an upper floor material is laid on the floor joist, while a suspension tree is hung on the beam or the joist.
A field edge is fixed to the suspension tree and supported, and the floor edge ceiling material is supported by the field edge.

[0003]

In the above-mentioned prior art, the work of suspending the suspended tree and the lower floor of the suspended tree with respect to the suspended tree are carried out because the suspended tree suspended from the beam is supported on the downstairs ceiling material via the ridge. There is a disadvantage that the work of assembling the ceiling material is complicated.

The present invention focuses on such disadvantages of the prior art,
It was created with the aim of reducing the number of parts and the complexity of on-site construction, shortening the construction period, and providing an inexpensive wooden building.

[0005]

A joist is fixedly attached to a horizontal member such as a beam, a floor joist is provided above the joist and a ceiling joist is provided below the joist, and an upper floor material is provided above the floor joist. In this case, the lower floor ceiling material is fixed to the ceiling joist.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a first embodiment of a wooden building according to the present invention; FIG.
FIGS. 5, 6 and 7 show second, third and fourth embodiments, respectively. FIG. 1 is a perspective view of a main part with some parts omitted, and FIG. 2 is an exploded view of FIG. FIG. 3 is a perspective view, FIG. 3 is a cross-sectional view of a main part, and FIG.

[0007] In the drawing, reference numeral 1 denotes a beam erected on a pillar 2 using a beam receiving member 3 (only one end is shown in the drawing, but the other end is also omitted, so that the beam 1 has a longitudinal portion). A joist hanger 4 is arranged along the direction, and the upper side of the joist hanger 4 is fastened to the beam 1 at the lower side with a nail 5,..., And the upper surface 4a of the joist hanger 4 and the beam 1 Is provided on the upper side of the side surface 1b.

[0008] In addition to the joist rack 4 and the beam 1 shown in the figure, another joist rack and beam are assembled with another pillar opposite to the pillar 2 in the figure. In short, each of the beams 1, the joists 4 and the floor joists 7 and the ceiling joists 8 described later are shown only at one end in the drawings, but the other ends are also substantially the same as the ones shown in the drawings. Omitted.

A notch 9 is provided at the end 4 'of the joist rack 4,
The column 2 is arranged so that the notch 9 partially engages the column 1 and a beam 1 ′ disposed between the column 1 and another column in a direction perpendicular to the beam 1.
The end 4 ′ is fixed to the column 2 with a nail 5.

An engaging groove 10 for the floor joist 7 and a receiving groove 11 for the ceiling joist 8 are provided on a surface 4b of the joist 4 facing the other joist.

The engaging groove 10 for engaging the floor joist 7 is formed in a vertical rectangular shape with the facing surface 4b side and the upper surface 4a side of the joist mounting 4 open. The receiving grooves 11 which are provided in a suitable number at the upper end along the engaging grooves 10 and have substantially the same depth as the engaging grooves 10 are provided below the joist rack 4 in the horizontal direction.

The floor joist 7 is engaged with the engaging portion 6 and placed on the joist rack 4. The first engaging portion 13 is adjacent to and below the first engaging portion 13. Each of the second engaging portions 14 engaging with the engaging groove 10 is provided at an end, and the first engaging portion 13 is provided.
To the engaging portion 6, the second engaging portion 14 to the engaging groove 10, and the end portion is fixed by oblique nailing (the point of attachment is omitted in the drawing). The floor joist 7 is supported between the joists 4 facing each other, and the upper surface 7a of the floor joist 7 is
On the same horizontal plane as the upper surface 1a.

The ceiling joist 8 is provided with an engaging projection 15 for engaging with the receiving groove 11 on an end face thereof. It is fixed by hitting (the point where the nail is attached is omitted in the drawing). It is supported by the joist 4 and an appropriate number of bridges are installed between the opposing joists in the same manner as the joist 7. On the same horizontal plane as the lower surface 4c.

In the figure, reference numeral 16 denotes an upper floor material which is placed on the floor joist 7 and the beam 1 whose upper surfaces are aligned with each other and is fixed thereto, and 17 is a floor whose lower surfaces are aligned with each other. It is a downstairs ceiling material that is overlaid on joists and joists from below and fastened to them.

Since the upper surfaces of the floor joists 7 and the beams 1 are on the same horizontal plane, each part of the upper floor material 16 can be laid without unevenness. Similarly, the joists 4 and the ceiling joists 8 are provided. Are located on the same horizontal plane, no unevenness is generated on the lower ceiling member 17. Note that a plywood or a structural panel is used as the floor material for the floor.

In the second embodiment shown in FIG. 5, a ceiling joist 8 is disposed immediately below a floor joist 7, and the remaining points are the same as in the first embodiment.

In the third and fourth embodiments shown in FIGS. 6 and 7, instead of the receiving groove 11 of the first and second embodiments, the lower engagement groove 11A and the lower end of the joist hook 4 are appropriately provided. A plurality of engaging protrusions 1 provided on the end surface of the ceiling joist 8 in the lower engaging groove 11A.
The third embodiment adopts a configuration in which the ceiling joist 8 is arranged at a position separated from the floor joist 7 as in the first embodiment, and the fourth embodiment is similar to the second embodiment. Similarly, the ceiling joist is arranged immediately below the floor joist 7, and the remaining points are the same as in the first embodiment as indicated by the same reference numerals.

The first and second engaging portions 1 of the floor joist 7
By engaging the members 3 and 14 with the engaging portions 6 and the engaging grooves 10, the joining strength between the members is increased, and as described above, the members can be put to practical use only by being fixed with a slant nail, as described above. Labor saving can be achieved.

The beams 1, the columns 2, the joists 4, the floor joists 7, and the ceiling joists 8 shown in the respective embodiments are made of so-called glued laminated wood which is fixed to each other by combining wood pieces, and the glued laminated wood is precut at a factory. Secondary processing to make building materials.

Even if the beam is not a so-called beam other than the beams 1 and 1 ', it can be used instead of the beam if the joist is attached and the beam has the same load resistance as the beam of the present invention. No problem.

[0021]

The present invention has the configuration described above,
The height of the floor (upper floor) or ceiling (downstairs) can be easily changed by changing the mounting height of the joist hanging members, and the lower floor ceiling material can be easily used because there is no need to use hanging trees. It is easy to assemble, and it is possible to expect a significant cost reduction by reducing the material cost or shortening the construction period by reducing the number of parts. In addition, the joist with the ceiling material on the lower floor is mounted on the wooden house shaft. Since it functions as a part of the assembled component, a robust wooden building can be provided.
