Description

[Detailed explanation of the idea] The present invention relates to an earthen wall using porous plywood.

Ancient Japanese architecture used earthen walls that matched the natural climate, absorbing indoor moisture during rainy weather, and releasing the absorbed moisture during sunny weather to moderate the humidity. It is known to have excellent soundproofing and heat insulating properties, as well as fireproofing properties, making it suitable for people's lives and health.

On the other hand, many modern buildings have thin walls inside and outside with insulation material in the walls, and even though they have insulation properties, they have poor moisture absorption, and the indoor humidity is significantly influenced by the weather and may cause condensation; especially at high temperatures. I often felt uncomfortable during the humid summer.

However, in order to finish a modern building with a traditional clay wall, the pillars should be cut through several tiers, placed in the place where the walls are made for mass production, and then split bamboos would be woven vertically and horizontally, one by one, and assembled. Currently, this ancient method of constructing earthen walls is no longer practiced, as it requires a great deal of labor and materials to coat the wall with earth and make it a rough earthen wall.

The purpose of the present invention is to provide an earthen wall that has the same functions as conventional earthen walls, is strong, and can be constructed quickly.

In this invention, porous plywood 1 is used as the wall core, and rough wall earth 2 is placed on both sides of the wall.
It is an earthen wall characterized by coating the surface with a finishing material 3 such as plaster, and then applying a top coat.

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

In FIGS. 1 and 2, a perforated plywood board 1 with a large number of holes 4 formed in a framework based on pillars 9, foundations 6, girders 7, and eaves beams 8.
is attached as a wall core by nailing.

The perforated plywood 1 can be easily attached to the frame by nailing, and the frame is firmly fixed due to the solid wall structure.

On the other hand, it not only saves on pillars and structural materials, but also saves carpenter labor.

Rough wall soil 2 is applied to both sides of the porous plywood 1 to form a rough wall.

The adhesion of the rough wall soil 2 to the porous plywood 1 is extremely good and does not cause any peeling.

Then, the surface is coated with an intermediate coat and a top coat using a finishing material 3 such as plaster to complete the earthen wall of the present invention.

The earthen wall of the present invention has a solid wall structure using perforated plywood 1 as a reinforcing plate, and has a load-bearing structure in which the framework, foundation, pillars, girders, and perforated plywood are integrated. .

Like traditional earthen walls, these earthen walls help maintain a moderate level of indoor humidity, and they also have sound and heat insulation properties.

In the earthen wall, the porous plywood 1 is sandwiched between the rough wall earth 2 and the finishing material 3 from both sides, and is not exposed to the outside, so it has good fire resistance.

In the figure, 10 is an anchor bolt, 11 is a nail, and 12 is a drainer.

The perforated plywood 1 can be produced by punching holes 4 in commercially available plywood, and can also be produced in a factory.

The holes 4 of the porous plywood 1 are, for example, about 40 m long and square, but the size, shape, and number of the holes 4 are not particularly limited. For example, the shape can be circular, triangular, star-shaped, etc. .

According to the present invention, the following effects are achieved.

■ Perforated plywood can be produced in a factory.

(2) It is easy to attach the perforated plywood to the frame, and the frame is significantly stiffened after installation.

■ Rough wall soil adheres well to porous plywood.

After completion, the wall soil is difficult to peel off.

■ By using perforated plywood, it is possible to supply load-bearing earthen walls that are as strong or stronger than conventional earthen walls for use in general housing at a low cost.

On the other hand, it also saves on columns and structural materials.

■ Construction period is fast.

■ Similar to traditional earthen walls, it absorbs and releases moisture depending on the indoor humidity to maintain an appropriate level of indoor humidity.
It also has heat insulation properties, and since the perforated plywood is not exposed, it is also excellent in terms of fire prevention.
