Description

[Detailed Description of the Invention] The present invention relates to a wooden building and its construction method;
The details relate to the structure of the flooring material and its construction method.

BACKGROUND OF THE INVENTION In recent years, there has been a desire to improve the performance of buildings, especially houses, in terms of fire protection, heat insulation, sound insulation, etc., and various fire prevention building materials, heat insulation, and sound insulation materials have been used, and their construction methods have also been studied and improved.

However, in wooden houses that use wood as a structural material, such as frame construction methods and frame wall construction methods, there are various limitations in the construction methods, making it difficult to efficiently improve fire prevention, heat insulation, and sound insulation performance. Especially 2
No suitable material or construction method could be found for the flooring on the first and third floors.

Therefore, the inventors studied the above-mentioned problems and completed the present invention. That is, the first invention is a wooden building using ALC board as a flooring material, and the second invention is a wooden building using ALC board as a flooring material, and the second invention is a wooden building using ALC board as a flooring material. Place a piece of plywood wider than the member, then place the ALC board on top of the plywood so that its edge is above the structural member, and then
Relates to the method of constructing wooden buildings in which ALC plates are fixed with fasteners.

In addition, in the present invention, wooden buildings refer to:
This applies to buildings that use wood as structural materials such as beams, columns, and foundations, and are built using traditional frame construction methods.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a plan view showing a floor according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA', and FIG. 3 is a sectional view taken along the line BB'.

That is, FIG. 1 shows an example in which the ALC plate material 1 was constructed on the floor of an upper floor.

The ALC plate material 1 is placed on the plywood 3 fixed on the wooden frame 2 and the floor beam 6, and the end of the ALC plate material 1 is located above the frame frame 2 and the floor beam 6. placed. The overhanging portion of the plywood 3 is fixed with fasteners such as bolts 4 and nuts 5.

Placing the ALC plate material 1 so that the end thereof is located above the structural members such as the frame beams 2 and the floor beams 6 is as follows:
This is to allow the structural members to directly support the load acting from the top surface of the ALC plate 1, and to avoid applying shearing force to the plywood 3 as much as possible.

The ALC plate material 1 used in the present invention is Japanese Industrial Standard JIS
Manufactured using a manufacturing method similar to A5416-1979,
It is a product of high quality and has characteristics that can withstand use as a floor. Usually the thickness is 100mm or more and the allowable load is 240Kg/m ² or more.

Structural materials such as the wooden frame 2 and floor beams 6 may be used as long as they have a thickness and number that have strength that complies with the Building Standards Act, and in this example, the wooden frame 2 is 105 mm x 105 mm and the wooden frame 2 is 105 mm x 360 mm. wooden beams 6 were placed at intervals of 1800 mm.

The plywood 3 facilitates the adhesion of the ALC board 1, and utilizes the flexibility of the plywood 3 to avoid stress and distortion occurring at the bonded portion of the ALC board 1 and the plywood 3, making it suitable for use as flooring material for wooden buildings. Used to improve the durability of For the above purpose, it is preferable for the dimensions of the plywood 3 to be as long and thick as possible, and it is usually 2 m or more in length, 240 mm in width, and 12 mm in thickness.
If it is above a certain level, there is no practical problem. The plywood 3 is fixed using nails or bolts/nuts (not shown) in the case of a base or a frame.

To fix the ALC plate material 1 and the plywood 3, the ALC plate material 1 is fixed to the overhanging portion of the plywood board 3 using fasteners such as bolts and nuts 5.

The number of bolts 4 nuts 5 to be fixed is 600mm wide.
It suffices to attach them at one or two locations per ALC plate material.

In addition, when constructing the ceiling board 7, hang the ceiling hanging bracket 8 from the 1 part of the ALC board and attach it to this.

When finishing the floor surface, it is best to fill the gaps and recesses of the ALC board 1 with gypsum mortar, smooth it, apply plywood, etc. to the entire surface, and then apply folding or carpeting to the top surface.

Since the wooden building of the present invention has the above-mentioned configuration, it has superior indoor insulation and sound insulation performance compared to conventional wooden buildings and lightweight steel buildings, and
Especially when the floor is on an upper floor, the fire resistance against fire coming from downstairs can be further improved by using ALC board and large cross-section wooden beams.

In construction, the conventional joist assembly can be omitted, and the construction is completed simply by attaching ALC board to the long plywood fixed to the top surface of the wooden structural material, so it is easy to use steel frame craftsmen like those for steel frame buildings. It is extremely easy to install as only a carpenter is required.

Since the wooden structural materials and ALC board are attached through plywood, even if the building sways or distorts, the flexibility of the plywood can avoid external forces and improve the durability of the building.

Since the wooden structural materials and ALC board are attached via plywood, the flexibility of the plywood absorbs vibrations applied to the floor, improving livability.

Because the structural members directly support the large loads that ALC board flooring receives from above, it is resistant to vertical loads from above.

It has the following effects.
