Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a corrugated plywood and a roof structure and floor structure using the same.

[0002]

[Prior art]

 In a wooden construction, the conventional roof structure has horizontal rafters 1 and 2 horizontally arranged in a stepped manner as shown in FIG. It is said that a large number of roof plates 4 are struck on the upper surface, waterproof paper 5 is laid on the upper surface, and roof tiles 6 are fixed on the waterproof paper 5 to roof tiles 7.

As for the floor structure, as shown in FIG. 5, a floor board support rod 9 is laid in parallel on a horizontally fixed joist (floor beam material) 8 and fixed, and a floor board 10 is struck and fixed. Although not shown, or not shown, a large number of tatami supporting floor plates are laid on the joist 8 and tatami mats are placed side by side on the upper surface thereof.

[0004]

[Problems to be solved by the device]

 Since the above-mentioned conventional roof structure is made up of an extremely large number of members, the material cost will increase, and at the same time, it will require a great deal of time and labor to prepare and process the material and assemble it on site. In addition, it may lead to an accident such as stepping off between rafters and falling while roofing. In addition, the conventional floor structure also requires a large number of members, though not as much as the roof structure, and thus requires much labor for processing and assembling. The present invention is mainly intended to solve these problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the corrugated plywood of the present invention has a corrugated uniform cross section as shown in FIG.

At this time, at least one surface thereof is waterproofed if necessary. As the waterproof treatment, a waterproof paint is applied to the plywood, or a waterproof impregnating agent is permeated. The thickness t of the plywood is set to about 9 to 12 mm, the wavelength L of the waveform is set to about 130 to 150 mm, and the total height (dimension from the lower surface to the upper surface) h is set to about 25 to 60 mm. In addition, for convenience, the whole plywood is a rectangular plate, the width B is about 60 to 100 cm, and the length A is about 1800 to 2700 mm.

In the corrugation of this corrugated plywood, corrugated male and female molds are manufactured, and a flat plywood of a normal structure which is softened by steaming with heating steam is inserted between these molds, and subsequently, The male and female molds are brought close to each other and the plywood is pressed into a corrugated form, cooled to a certain temperature or lower, and then taken out.

The above-mentioned corrugated plywood is the roof structure and floor structure of the present invention, which will be described below.

First, the roof structure is as follows. That is, as shown in FIG. 2, at least one surface of the corrugated plywood 11 waterproofed at the upper surface of the roof beams 1 and 2 arranged side by side in a staggered manner has its waterproof surface on the upper side. In addition, the corrugated grooves m are laid so as to form an oblique shape in a direction orthogonal to the roof beam members 1 and 2, and fixed with a fastener such as a nail.

At this time, the corrugated plywood 11 has a total height h of about 40 to 60 mm, and the left and right ends a and b and the upper and lower ends c and d are the left and right ends a of the adjacent corrugated plywood 11. , B and upper and lower ends c, d are overlapped to prevent rain leakage.

After that, the roof tiles 6 are directly fixed to the upper surface of the corrugated plywood 11 without laying the conventional waterproof paper 5, and the roof tiles 7 are laid.

In this roof structure, since the corrugated plywood 11 of the present invention is used, the conventional rafters 3 and the roof boards 4 which are used in large numbers, and the conventional waterproof paper 5 laid on the entire surface of the roof 5 By eliminating the need for such things, the assembly process is dramatically reduced.

Further, since the corrugated plywood 11 can be increased in its size, the assembling process is simple and the waterproofing process allows the rainwater to penetrate through the roof 7 even if rain leaks from the roof tile 7. Leakage is prevented, and the corrugated groove m smoothly guides the rainwater leaking from the tile 7 surface downward along the corrugated plywood 11 to promptly remove it to the outside of the roof, and at the same time, the air circulation is good. In addition to removing moisture to prevent air flow, this groove m forms an air layer with a good heat insulation effect to prevent dew condensation on the attic, as well as increase indoor temperature in summer and winter. It suppresses the decrease in indoor temperature.

Next, the floor structure is as follows. That is, as shown in FIG. 3, the corrugated plywood 11 is provided on the upper surface portion of the floor beam 8 arranged in parallel on the floor such as the first floor or the second floor so that the corrugated groove m is orthogonal to the floor beam 8. Cross over and fix. The corrugated plywood 11 used here has an overall height h of about 25 to 60 mm, and does not necessarily have to be waterproofed.

The floor plate 10 is fixed to the upper surface of the corrugated plywood 11 with a fastener such as a nail. Then, the upper surface of the floor board 10 is used as a walking surface, or a tatami mat is laid directly on the upper surface of the corrugated plywood 11. At this time, tatami mats may be laid on the upper surface of the floor board 10 for supporting the tatami mats.

In this floor structure, the use of the corrugated plywood 11 eliminates the need for the conventional floor-board supporting rods 9 in the case of a Western-style room. Further, since the corrugated plywood 11 can be increased in size, the labor of assembling is reduced as compared with the conventional floor board supporting rods 9 and the floor board 10 for supporting the tatami mat, and the corrugated groove m is If the air flow under the tatami mat is smooth, and if the tatami mat is not laid, the air flow is cut off, an air layer with a good heat insulation effect is formed under the floorboard, and the same effect as described above is achieved. And the one with waterproof treatment prevents moisture under the floor from reaching the tatami mat.

[0017]

[Effect of the invention]

 According to the corrugated plywood of the present invention configured as described above, the roof structure can be constructed at low cost and without the trouble of working or assembling, and the floor structure can be constructed with less labor. It improves the durability by keeping moisture away from the floor and the floor surface and suppresses the temperature change in the room to make it comfortable to live in.

Further, according to the roof structure or floor structure of the present invention, in addition to the effects obtained by the corrugated plywood as described above, it is necessary to change the basic structure of the conventional roof beams and floor beams. It becomes nothing.
