Abstract

PURPOSE:To prevent the life from being shortened and reduce the construction period, by attaching wall panels on which a structural plywood is fitted at least at one face of a panel frame with the external peripheral frame, between columns of a building, using the attached face of the structural plywood as the inside face and eliminating bracings. CONSTITUTION:A structural plywood 4 is divided vertically and attached on one side face of an external peripheral frame 1 by use of a fixing means. A heat-insulating material 5 is charged in the space partitioned by the external peripheral frame 1 and the auxiliary frame 2 of a wall panel A. An air-permeable sheet 6 is spread on the opposite side against the structural plywood 4 of the wall panel A. The structural plywood 4 of the wall panel A is fitted to the plane made by the right and left columns B, the sill frame C, and the girder D at the indoor side. The fitted wall panel A is fixed with nails or the like on the columns B, the sill frame C, and girder D through the structural plywood 4 and the external peripheral frame 1. In this way, when the wall panel A is used, since the external peripheral frame 1 fixed to the columns B, the sill frame C, and the girder D and the structural plywood 4 are constituted difinitely, the columns B are prevented from leaning toward the structural plywood 4 side or the reverse side and hence, these bring out the same action with bracings.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building construction for constructing a building constructed by a conventional method of constructing building components such as columns and girders with tenon and holes for inserting the tenons. Regarding the method.

[0002]

2. Description of the Related Art Conventionally, in a building constructed by the conventional method as described above, it has been obliged to use braces at required places because of the demand for earthquake resistance. However, indoor heating and cooling are becoming common these days, and with the widespread use of this heating and cooling, it has become possible to reduce the amount of fuel and electricity used for this, and the space between the outer peripheral surface of a building and the interior of the building. Insulation has come into use.

A pillar that is widely used at present is a square bar having a cross section called 3.5 inch square with one side of 10.5 cm.
On the other hand, as the above-mentioned heat insulating material, the thickness of the heat insulating material is required to be about 10 cm in order to function effectively.

Therefore, if a heat insulating material having a thickness of 10 cm is used, the space dimension between the outer periphery and the room, that is, the cross-sectional dimension of the column is 10.
It is almost the same as 5 cm, and there is no room for bracing. Therefore, it was approved that the brace can be omitted by stretching the structural plywood on the pillars and fixing the two pillars.

Therefore, conventionally, a construction method has been generally used in which at least two right and left sides of this structural plywood are used as pillars and nailed along the outer peripheral surface of the building to fix the left and right pillars. is there.

[0006]

As described above, when the structural plywood is used on the outer peripheral surface of the building, a heat insulating material or a lining material is used on the inner surface of the structural plywood. However, these allow the indoor humidity to pass through.

On the other hand, since the structural plywood stretched on the outdoor side is cooled at a cold outside temperature, the moisture that has passed through the heat insulating material and the lining material hits the cooled structural plywood and is cooled to a dew condensation state. turn into.

In addition, since most of the outer wall material stretched on the outer surface of the structural plywood is permeable to humidity, the structural plywood is also exposed to humidity due to rain and snow, and these combine to cause peeling and corrosion of the structural plywood. Occurs, which shortens the useful life of the building.

Further, when structural plywood is used on the outer peripheral surface of a building, or when conventional wooden boards are used, it is not necessary to have the same thickness as structural plywood for lining the room. , Plywood must be used as a base for decorative liners such as fireproof boards or vinyl cloth, and plywood must be used both indoors and outdoors to use double plywood. There were also drawbacks.

The present invention solves the above-mentioned problems in the method of constructing a building that eliminates the braces of the conventional construction method, and prevents the life of the structural plywood for eliminating the braces from deteriorating due to dew condensation and the like. It is an object of the present invention to provide a method for constructing a building in which it is possible to omit the plywood for underlaying on the indoor side and to construct using a wall panel manufactured in advance in a factory.

[0011]

SUMMARY OF THE INVENTION The present invention relates to a method of constructing a building for achieving the above object, which method comprises:
In a building where the brace of a building constructed by a conventional method of framing columns, girders, etc. should be used, at least two sides on the left and right are formed with dimensions approximately the same as the dimensions between the columns, and the upper and lower two sides are The wall panel in which the structural plywood is stretched on at least one surface of the panel frame which is formed to have a size close to the vertical dimension of the pillar to be inserted and which constitutes the outer peripheral frame of wood, and the surface in which the structural plywood is stretched The inside is attached to between the pillars of the building to eliminate the braces.

[0012]

According to the method of constructing a building of the present invention, of the wood of the outer peripheral frame forming the outer circumference of the wall panel, at least the left and right two woods are fixed to the left and right pillars by fixing means such as nails. As a result, the structural plywood stretched over the wall panel cannot be deformed within its plane, such as being deformed into a rhombus, etc., due to its thickness, so that the left and right pillars are on the side of the structural plywood or on the opposite side. It prevents leaning and eliminates the need for brace use.

And, with this structural plywood as the interior side,
Since the wall panel is fixed between the columns, when the wall panel is used as a boundary between indoor and outdoor, the heat insulating material is used on the outdoor side of the structural plywood. With this heat insulating material, the outside air temperature is not directly applied to the structural plywood, so that the temperature of the structural plywood is maintained at the room temperature and does not fall to the outside air temperature.

Therefore, the structural plywood is kept at room temperature even in a room with high humidity, and the moisture of rain and snow is vented to the outer surface of the heat insulating material or the wall panel with waterproof, windproof, and moisture-exhausting properties. Since it is possible to prevent the structural plywood from reaching the structural plywood by stretching the sheet, dew condensation does not occur on the structural plywood and the service life of the building is not shortened.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the case where the present invention is applied to the wall surface of the boundary between the indoor and the outdoor will be described with reference to FIGS. FIG. 1 shows an outer wall panel A for use as a boundary between the interior and the exterior used in the present invention. The outer peripheral frame 1 is formed by combining timber of 30 × 91 mm into a rectangle.

The outer frame 1 has a lateral dimension of 808 mm, which is the dimension between columns B between halves in a general building using 3.5 square columns, or 85 which is half between columns B between one column.
8 mm, and the vertical dimension is 2 between the base frame C and the girder D
The length is 800 mm, and the auxiliary frame 2 is placed between the left and right sides.
, And the penetrating material 3 centered on a position 1820 mm from the bottom
Is fixed to the outer peripheral frame 1.

A thickness of 9 is formed on one surface of the outer peripheral frame 1.
mm, the structural plywood 4 referred to as 3 × 6 is divided into upper and lower parts and stretched by fixing means such as nails. The above-mentioned penetrating material 3 serves as a joint portion of the structural plywood 4. It is a thing.
The space defined by the outer peripheral frame 1 and the auxiliary frame 2 of the wall panel A is filled with a heat insulating material 5 such as glass wool, but the heat insulating material 5 is not limited to glass wool, but a material having a heat insulating effect. If so, this can be adopted.

Further, a ventilation sheet 6 such as, for example, an ultra waterproof ventilation sheet of Taiyo Plastic Co., Ltd. is stretched on the surface of the wall panel A opposite to the structural plywood 4. The ventilation sheet is waterproof, It is desirable to use a material that has windproofness and moisture drainage and is hard to pass rainwater.

On the outer peripheral surface of the outer peripheral frame 1 of the thus constructed wall panel A, an airtight sealing material 7 having a thickness of 5 mm and a width of 80 mm, such as a closed-cell flexible sponge material, is attached. 2 to 4 show the state of use of the wall panel A, which shows the state in which the wall panel A is used between columns having an interval of 1.

The wall panel A is fitted between the left and right pillars B and the base frame C and the girder D with the structural plywood 4 as the interior side, and the airtight sealing material 7 is a slight gap formed between them. It is compressed and fills this void, blocking the outside air. The thickness of the wall panel A is 91 mm in width of the outer peripheral frame 1,
Since the thickness is 100 mm, which is the sum of the thickness of 9 mm for the structural plywood 4, it is almost the same as the cross-sectional width of 100 mm for a 3.5-inch square column. Therefore, the surface of the structural plywood 4 and the surface of the column B are Can be flush.

The fitted wall panel A is fixed to the pillar B, the base frame C, and the girder D through the structural plywood 4 through the outer peripheral frame 1 by nailing or the like.
As described above, since the interior side of the wall panel A is flush with the pillar B, the refractory board or vinyl cloth extends from the structural plywood 4 to the pillar B without causing a step on the surface. It is possible to stretch the interior material for makeup such as.

On the outside of the room, the outer wall can be finished by the same means as before, for example, by penetrating the outer wall and mortaring the outer wall.
The outer wall finish is not limited to this method. As described above, when the wall panel A is used, the pillar B, the base frame C, and the outer peripheral frame 1 fixed to the girder D and the structural plywood 4 are integrally configured. Prevents leaning toward one side or the other, and acts like a brace.

Further, the structural plywood 4 is located on the indoor side,
Since the temperature of the outside air is blocked by the heat insulating material 5, the temperature of the outside air is not transmitted to the structural plywood 4, and the structural plywood 4 is kept at the room temperature. Therefore, even if the room has high humidity, there is no dew condensation because the structural plywood 4 is cold.

Further, the humidity due to the rain and snow of the outside air is mainly blocked by the ventilation sheet 6 and does not reach the structural plywood 4,
Even if it reaches, the temperature of the structural plywood 4 is higher than the outside air temperature, so that the outside of the structural plywood 4 does not condense.
Therefore, delamination of the structural plywood 4 due to dew condensation and strength reduction due to corrosion are prevented, the useful life of the building is prevented from being shortened, and long-term use can be endured.

Next, as a second embodiment of the present invention, a case where the wall panel is an inner wall panel will be described with reference to FIGS. In the wall panel E in this case, the upper and lower surfaces of the left and right frame 11 having a thickness of 22 mm and a width of 91 mm which are fixed to the right and left columns B are struck with the upper and lower frames 12 having a thickness of 16 mm and a width of 91 mm to form the girder D and the base frame C. The outer peripheral frame 13 having an outer shape with a height of 2450 mm and a width of 808 mm is formed for the case where the distance between the pillars B, which is smaller than the distance between 2800 mm and 2,800, is half.

The auxiliary frame 1 is provided at the left and right centers of the outer peripheral frame 13.
4 is fixed and the left and right frames 11 are 455 m from the bottom.
A penetration member 15 having a thickness of 16 mm and a width of 100 mm is dented in the left and right frames 11 and is struck on both front and rear surfaces of the outer peripheral frame 13 centering on each m. Incidentally, the penetrating material 14 to be hit on one surface of the outer peripheral frame 13 may have a part having a width smaller than the above size.

Then, on one surface of the outer peripheral frame 13, a structural plywood 4 having a thickness of 9 mm is struck by a nail or the like, and the outer peripheral frame 13 is
And the structural plywood 4 are integrated into a wall panel E for the inner wall having a total thickness of 100 mm. As shown in FIGS. 5 and 7, the wall panel E is inserted between the pillars B so that the lower side thereof is located at a position 112 mm higher than the base frame C, and nails are directed from the left and right frames 13 toward the pillar B. By hitting,
Fix between columns B.

Therefore, as in the previous embodiment, the structural plywood 4
The surface of the pillar B and the surface of the pillar B are flush with each other, and it is possible to apply a decorative material such as vinyl or cloth without forming a step on the surface,
There is no need to apply plywood as a base. Further, when the interior material for makeup is attached to the opposite surface of the structural plywood 4, the plywood is attached from above the outer peripheral frame 13 to the pillar B.

Also in this embodiment, similarly to the previous embodiment, the strength of the structural plywood 4 can prevent the left and right columns B from inclining, so that there is no need for bracing. In each of the above-mentioned embodiments, the thickness of the wall panels A and E is 100 mm, and the pillar B is
Although the cross-sectional dimension of 100 is set to 100 mm so that both surfaces are flush with each other, the pillar B may be made of a material having a cross-sectional dimension larger than this, or the outer peripheral frames 1 and 13 may be made thinner. By the means, the interior material for makeup attached to the wall panels A and E may be a true wall which is recessed more than the pillar B.

[0029]

As described above, according to the present invention, by fixing the outer peripheral frame which is the panel frame of the wall panel to at least the left and right columns, the structural plywood of the wall panel prevents the columns from tilting. , It works like the brace in the conventional method.

Therefore, the bracing, which is an essential requirement in the conventional construction method, can be omitted, a heat insulating material having a thickness close to the cross-sectional dimension of the pillar can be housed between the pillars, and the effect of cooling or heating can be enhanced. .

Since the structural plywood of the wall panel is on the indoor side, it is possible to install a heat insulating material on the outdoor side, and the outside air temperature is blocked by this heat insulating material and does not add to the structural plywood. The structural plywood is kept at the room temperature, and even if the indoor humidity is high, no condensation occurs on the structural plywood.
Therefore, the structural plywood does not cause delamination or corrosion due to dew condensation, and the service life of the building employing this construction method is not shortened.

Moreover, the wall panel can be manufactured in a factory with the standardized size in advance by standardizing the size of the building, and this can be mounted on the pillar between the columns on site. When constructing a building, the man-hours can be simplified, the construction period can be shortened, and manpower can be saved.
