Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problems: health problems are recognized because a conventional building material gathers mold due to the insufficient absorption and discharge of moisture and does not have the functions of adsorption, absorption and decomposition of an organic compound such as formaldehyde, through a wallpaper and a plastered wall are used as the conventional building material in many cases; and the conventional plastered wall and coating of diatomaceous earth require high costs associated with a plastering skill, due to the indispensable use of adhesive paste, cause coming-off or cracking incapable of being solved by the skill alone, and bring about the harmfulness of an adhesive or the adhesive paste and the reduction of the effect of the diatomaceous earth because necessary steps make a construction period long. <P>SOLUTION: The environmental function of the diatomaceous earth is provided by employing an integrated wooden panel in which the microporous diatomaceous earth with higher air permeability and moisture absorbing/desorbing properties is infilled into an internal space of a wood structure by making the most of the air permeability and hygroscopicity intrinsic in the porous wood. This technological innovation achieves the promotion of local jobs and the development of local industries by the utilization of the local thinned wood of Japanese cedar. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

The present invention exhibits environmental functions by including baked diatomaceous earth in a halved structure of cedar thinned wood logs. The present invention further relates to a method for forming and manufacturing a low-cost wooden panel.

Diatomaceous earth walls are said to be good for the living environment, but peeling and cracking occur on the walls.
In addition, the diatomaceous earth wall has a technology for improving radiation shielding performance.
Japanese Patent Application No. 2005-92735

Conventional building materials often use wallpaper and painted walls, but deficiency in moisture absorption and release is the cause of mold.
In addition, health problems have been recognized because it does not have the function of adsorption, absorption and decomposition of organic compounds such as formaldehyde.
In diatomaceous earth coating and painting, the use of glue is indispensable, and costs are incurred with plastering technology.
In addition, dropouts and cracks that cannot be solved by technology alone occur. It takes a work period as much as the process is necessary, and there is a decrease in the effects of adhesives and pastes and the effects of diatomaceous earth.
The present invention solves this.

Originally, wood has characteristics of air permeability and moisture absorption. It is a technological innovation that enhances performance by filling the interior space of the wooden structure with diatomaceous earth with fine porosity with higher air permeability and moisture absorption and desorption.
Providing the environmental functions of diatomaceous earth as an integrated wood panel.

According to the present invention, the ability of diatomite to absorb moisture, moisture release, fire resistance, heat insulation, radiation shielding, adsorption of toxic substances such as life odor and formaldehyde, absorption, decomposition ability is given to the wooden panel, and the living environment Contributes to improvement.
Since it is an integrated wood panel, it can shorten the construction period and is characterized by low-cost development.

The wooden panel is made of cedar thinning with the above performance, and the space is filled with baked diatomaceous earth. Construction is made easier by using a panel type with a structure with a connecting function. Excellent aesthetics.

It has the potential to have a significant improvement effect on sickness problems and health problems arising from the living environment.
Natural cedar thinned wood is environmentally friendly and is expected to be cost-effective in the development of low-cost fields and has a healthy environmental effect.

Shielding walls that are highly likely to be exposed to radiation, such as nuclear power plants, radiation processing facilities, medical institutions, research institutions, and shelters, can be used to improve radiation shielding ability.

The incombustible refractory diatomaceous earth inside the wooden panel structure of the present invention delays the spread of fire in the event of a fire. Or prevent it. Furthermore, it has a structure that leads to extinguishing fire with the same effect as applying sand, and has the possibility of use for fire prevention.
