DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor plate mounting structure for a wooden building, and more particularly, to a method of effectively utilizing natural energy to generate an air flow in a space in a wall, and the air flow to remove moisture and heat. TECHNICAL FIELD The present invention relates to a floor panel mounting structure in a wooden building suitable for being applied to a building having a system for performing the above.

[0002]

2. Description of the Related Art In general, the second floor of a wooden building is roughly classified into a single floor, a double floor, a combined floor and the like according to the size of the upholstery. The floor of a large room with a span of 3.6 m or more is hung on girders and joists. The interval between the joists is usually 45 cm, but may be 30 cm when the load is large.

FIG. 4 shows a frame structure of a second floor in the vicinity where the column 1, the beam 2, and the trunk 3 are orthogonal to each other, and a joist 4 is provided above the beam 2 at a predetermined interval in a direction orthogonal thereto. Every other hand.

[0004] A long receiving member 15 is attached to the waist 3 along the longitudinal direction. The floor boards 5 on the second floor are supported and arranged between the joists 4 arranged at predetermined intervals.

In recent years, in order to make effective use of wood, glued laminated wood called engineer wood has been widely used in place of such natural wood.
According to such a laminated wood, it is possible to produce a wood having a large cross section, which is difficult to obtain with a natural wood, and it is possible to provide a wood having a uniform strength due to a small amount of water. Therefore, by using such a laminated wood, it has become easy to set the area of the room large.

Further, in recent years, as a wooden building, a building having a system that effectively utilizes natural energy has been proposed. In such a building, for example, as shown in FIG. 5, the heat insulating material 6 is effectively used, and a comfortable living environment is created. That is, by applying a high-performance heat insulating material 6 and an airtight material to the outside of the building, the inside and the outside of the house are completely thermally separated from each other, and the heat and cold are cut off.

More specifically, an inner ventilation layer 7 is formed on the inner side of the heat insulating material 6, and this inner ventilation layer 7 reduces the temperature difference in the room by natural circulation of the room temperature in winter and ventilates in summer. In this way, ventilation of exhaust, heat, and cool air is performed. Further, an outer ventilation layer 8 is formed outside the heat insulating material 6, and the outer ventilation layer 8 is formed.
Is open to the open air year-round, and is responsible for dehumidifying and exhausting heat from buildings.

On the second floor of such a building, for example, as shown in FIG.
The outer ventilation layer 11 is formed outside the inside, and the inner ventilation layer 12 is formed inside the heat insulating material 10, that is, in the space in the wall.

[0009]

In the case where the floorboards 5 are to be laid on the second floor of a wooden building using a glued laminated lumber or the like and employing a system that makes effective use of natural energy as described above. Has the following problems.

That is, the long side of the floor plate 5 arranged at the corner of the room can be nailed only to the portion received by the joist 4. For this reason, when weight is applied to a portion that is not received by the joist 4, there is a problem that the floorboard 5 is bent and a gap is generated. In addition, during construction, a large number of joists 4 are arranged and arranged, so that work in high places is troublesome.

Further, when a system that effectively utilizes natural energy is constructed, as shown in FIG. 6, an underfloor space 13 defined below the floor plate 5 and an inner ventilation layer 12 are formed.
A communication path for passing the air as shown by the arrow A must be formed between the two.

In view of such circumstances, the present invention allows the corners of the floorboards to be laid out in a stable posture,
It is an object of the present invention to provide a mounting structure of a floor plate in a wooden building that can easily communicate an underfloor space and an inner ventilation layer even in a building having a system that effectively utilizes natural energy.

[0013]

According to the present invention, a notch is formed in a hanging member arranged along a floor plate support member, and the floor plate is rigidly attached and the notch is used as a communication passage.
Also, if the room area is to be increased by using glued laminated timber, the hanging material is arranged along the girders, and the high-strength joists are directly attached using the metal fittings, thus making it difficult to construct the floor. Is reduced.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION In the mounting structure of a floor plate in a wooden building according to the present invention, notches are formed at predetermined intervals in a hanging member, and the hanging member is shifted slightly upward with respect to a horizontal member. Attach. In addition, a joist having a moderate strength in a strip shape is used, and this joist member is attached to a floor plate supporting member via a hardware.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention, and particularly shows a structure near a floor of a second floor in a wooden building.

The girder 20 connected to a pillar (not shown) is formed to have a large cross section by glued laminated wood or the like to form a large room, and is formed to be long. Such a girder 20
, A hook member 21 having substantially the same length is attached along the length direction. The hanging member 21 is thinner than the thickness of the girder 20, and its thickness is, for example, about 38 mm. Further, the height of the girder 20 is approximately half.

The hanging member 21 is formed with notches 22 which are open at an upper portion at predetermined intervals. And
The upper end 21a is attached so as to be located slightly above the upper end 20a of the girder 20. On the other hand, hanging material 2
1 is a metal fitting 2 so that it is alternated with the cutout 22.
3 is attached.

As shown in FIG. 2, for example, the coupling hardware 23 has two arms 24, 24, and a support 25 is formed to connect the lower surfaces thereof. Mounting pieces 26 are formed on both sides of the arm portion 24, and mounting holes 27 are formed in each mounting piece 26 so as to be separated by a predetermined distance. At the upper end of the mounting piece 26, a hooking piece 28 is formed by bending, and the hooking piece 28 has mounting holes 29 formed at predetermined intervals. The metal fitting 23 thus formed is made of metal and has appropriate strength.

On the other hand, the joist member 3 used in this embodiment
0 is formed in a strip shape from engineer wood, etc.,
It has a height substantially equal to the longitudinal length of the hardware 23. The joist member 30 is composed of long plate members 41 and 32 disposed to face each other, and a face plate 33 fitted and integrated between the plate members 41 and 32, and has appropriate strength. ing.

Hereinafter, the assembly will be described. The above-mentioned girder 20 is arranged so as to extend between two columns (not shown), and a hanging member 21 is attached in advance before being lifted upstairs. Also, the coupling hardware 23 is attached in advance.
And in this wooden building, no girder is installed. Therefore, one of the girders 20 as a floor plate support member is used.
The distance between and the other large beam 20 is set large.

After the girder 20 has been assembled in this way, a joist member 30 is attached between a pair of corresponding fittings 23, 23, and fixed with nails or the like. Thereafter, a large number of joist members 30 are sequentially passed in the same procedure.

When a large number of joist members 30 are hung, FIG.
As shown in (1), a floor plate 31 having a predetermined width is laid between the hanging member 21 and the joist members 30 arranged at predetermined intervals. The floorboard 31 laid on the floor of the second floor is fixed by driving nails into the upper end 21 a of the hanging member 21 and the joist member 30. At this time, the hanging member 21 may be similarly attached to a not-shown body difference or the like arranged at right angles to the girder 20, or the joist members 3 may be attached to both ends of the hanging member 21.
By passing 0, the other side surface of the floor plate 31 can be held similarly. Thereby, 4 of the floorboard 31
Since the side portions can be nailed, the floor plate 31 does not partially sink downward. That is, even when a person walks on the outermost part of the floorboard 31, the end does not rise.

On the other hand, an inner layer material (not shown) such as plywood is provided upright on the girder 20 near the room side. A panel-shaped heat insulating material 33 is provided upright on the outside of the girder 20 over the entirety. Therefore, in this building, external heat insulation is formed, and the inner ventilation layer 35 is formed in the thickness portion of the girder 20. An outer ventilation layer 38 is formed outside the heat insulating material 33. The inner ventilation layer 35 and the outer ventilation layer 38
Is spread in a planar manner in the up-down direction and the width direction, and is formed so as to surround the house. Thereby, the inner ventilation layer 35 is formed.
By passing warm or cold air through, it is possible to create a comfortable living environment throughout the year.

According to the present embodiment, the space between the underfloor space 36 defined on the lower surface of the floor plate 31 and the inner ventilation layer 35 is provided.
Since the hanging member 21 having the notch 22 is provided,
The space between the underfloor space 36 and the inner ventilation layer 35 is communicated via the cutout 22. Therefore, the underfloor space 36
The inside air can flow from the cutout portion 22 to the inner ventilation layer 35 as shown by the arrow B.

Further, according to the present embodiment, since a metal joint is used, when a large number of joists are mounted, the mounting is simplified. In addition, since a plate material having higher strength can be adopted as the joist member instead of a normal square bar, a small beam between the large beams can be eliminated. Therefore, the work of passing the small beams is not required.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example,
In the above-described embodiment, a building that configures a system that effectively uses natural energy has been described.
It can also be applied to buildings where the system is not configured. In that case, since the flow of air occurs in the wall, it is possible to prevent moisture and the like in the wall.

Further, in the above-described embodiment, a wooden building using laminated wood or the like has been described. However, the present invention can be applied to a wooden building using ordinary natural wood. In addition, hardware member 2
The shape of No. 3 is not limited to the shape of FIG. 2 at all, and other shapes of connecting hardware can be used.

Further, in the above embodiment, the floor plate arranged on the beam on the second floor has been described, but the present invention is also applicable to the mounting of the floor plate on the third floor or the first floor. In the case of the first floor, the base is configured as a floor plate supporting member instead of the beam 20. Further, the joist member 30 may simply be a square joist.

[0029]

As described above, in the mounting structure of the floor plate in the wooden building according to the present invention, the hanging material is slightly shifted upward with respect to the floor plate supporting member such as a beam, so that the notch is notched. By providing the part, it is possible to function as a communication path. Therefore, the underfloor space can be introduced into the passage in the wall, and moisture and the like in the wall can be prevented. Further, by attaching the joists via the connecting hardware, even a heavy joist member can be easily attached. In addition, if the strength of the joist member is made sufficiently large, it is not necessary to hang a small beam between the girders, and it is possible to eliminate the labor for hanging the small beams.

Further, in a wooden building in which external heat insulation is performed using a system that effectively utilizes natural energy, a passage in the wall can be easily secured.
