Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the technical field of composite building materials used for the construction of structures that can maintain their habitability and safety for many years.

[0002]

2. Description of the Related Art In recent years, prefabricated houses or houses that can be manufactured in factories have become widespread in order to reduce the housing area, shorten the construction period, and reduce construction costs. The number of thick-walled pure Japanese-style houses that are required is gradually decreasing. Instead, a mortar finish with a thin wall or a cement board method is widely used as a wall material because it is inexpensive and can be constructed in a short period of time.

[0003]

However, conventional multi-layer building materials for general houses are focused on weight reduction by foam molding of concrete and mass production by a factory method, and can be used for many years. The fact that it has robustness is hardly considered, and therefore it has poor seismic resistance, and also has insufficient soundproofing and heat insulating properties. In particular, it is unsuitable for weather resistance and durability under the hot and humid weather conditions of Japan. There were many things.

Under the retro tide, there is a growing tendency toward structures that can be maintained for more than a century, such as high-quality temples or old castles, and structures that can survive for many years and live for generations of families. There are many demands for building materials that can be used for building things, and so-called genuine orientation is increasing in place of buildings with a service life of at most 10 years as in the former scrap-and-build era, and it is possible to guarantee over 100 years. The development of building materials was desired.

The object of the present invention is to eliminate the drawbacks of conventional building materials and construction methods and to provide building materials that can survive for a long period of time.

[0006]

[Means for Solving the Problems] Japan has a land pattern where earthquakes frequently occur, and in order to maintain a building for a long period of time, it is necessary to first increase seismic resistance, and it is essential to increase fire resistance. Reinforced concrete materials are suitable for this, but cracks caused by shrinkage and deterioration due to acid and salt in the atmosphere were unavoidable. By compounding the agent, the shrinkage could be suppressed to about 1/2 of the conventional value.

Further, the concrete layer containing the durability improving admixture has few bubbles and voids, less invasion of carbon dioxide gas or chlorine ions, etc., and has resistance to freezing and thawing due to the presence of fine bubbles. It is strengthening.

Next, in contact with the concrete layer, about 1 / th of air
A heat-insulating material layer containing innumerable small bubbles, which mainly consisted of a rigid polyurethane foam having a thermal conductivity of 3, was provided to block unnecessary heat input and output.

A hollow layer is provided in order to improve heat insulation and sound insulation and to control unevenness of the building material.

Since it is almost impossible to change the pipes and wires when arranging them in the concrete layer, the pipes and wires can be repaired easily without repairing them inside the concrete layer of the outer wall, and can be easily repaired. They were all concentrated in the concrete block layer so that it was possible.

The inner wall of the dolomite plaster mainly composed of wood or lime is used to improve the humidity control effect in order to improve the habitability in the innermost part and to adapt the living environment according to the request of the resident. .

[0012]

EXAMPLE As shown in FIG. 1, a reinforced concrete layer having a durability-improving admixture having a thickness of 170 mm was provided on the outermost side, a rigid polyurethane foam plate having a thickness of 40 mm was attached to the outermost layer, and then a gap of 10 mm was provided. A layer of 100 mm thick concrete block containing reinforcing bars is piled up and layers of wood or calcareous dolomite plaster with a thickness of 20 mm are provided inside to form a five-layer structure with a total length of 340 mm. This structure can be mainly used as a wall material for houses.

In addition, as shown in FIG.
A reinforced concrete layer containing a durability-improving admixture having a thickness of 50 mm is provided, and a rigid polyurethane foam plate having a thickness of 50 mm is provided in contact therewith, and then 15 mm to 65 m.
A concrete block layer with a reinforcing bar having a thickness of 100 mm to 150 mm is provided with an air gap layer of m
With a mortar coating layer of m and a ventilation layer of 100 mm, a paulownia material layer with a thickness of 18 mm is provided inside and a total length of 4
It has a seven-layer structure of 98 mm to 598 mm. This structure is mainly used as a building material for floors, walls and ceilings of so-called warehouse buildings for long-term storage of goods.

[0014]

The concrete containing the admixture has a small dry shrinkage, the structure itself is dense, prevents the invasion of harmful gases and harmful ions, and has a small shrinkage strain to prevent cracking. In addition, the added admixture adsorbs invading harmful substances and exhibits resistance to freezing and thawing due to the minute air bubbles contained therein, so that the durability and weather resistance of the material can be maintained without causing deterioration. It has the characteristics that the durability and the seismic resistance are remarkably improved, and the life span is 10 times or more that of the conventional building.

Due to the heat insulation effect of the hard polyurethane foam material adjacent to the concrete layer, high heat from the outside is prevented and the effective heat in the room is not dissipated, and the cooling and heating efficiency is remarkably improved to make the living environment comfortable. It has features.

The internal void layer has a feature of improving the sound insulation effect of preventing invasion of unpleasant noise in addition to the heat insulation effect of suppressing heat transfer.

When a house is used for many years and the layout needs to be changed to perform plumbing work for water supply / drainage, gas or the like, or wiring for electric systems, the piping and wiring can be made concrete without damaging the concrete layer on the outer wall. By storing in the block layer, its position can be easily changed.

In the innermost part, a wood layer or a domalloy plaster layer mainly composed of lime, which has a high heat insulating property and can control the absorption and diffusion of water, is used to prevent a rapid temperature rise or drop and a humidity change in the room, and It has the characteristics that it can maintain a comfortable living environment without generation of mold, discoloration, and odor, and this multi-layered structure protects the residence and family from rain, wind, fire, or earthquakes, and it has been used for many years. The effect that enabled the use of.

[0019] Furthermore, in order to store valuable books, antiques, etc., not only earthquake resistance, fire resistance, anti-theft, but also ventilation for not only walls but also stilt floors or ceilings to control internal temperature and humidity. By using a seven-layer structural material that uses paulownia wood for the void layer and the interior, it has the feature that it can store goods for hundreds of years beyond the conventional storage structure.

Since a portion corresponding to a pillar or a beam is included in the multi-layer wall, a flat space is formed in the room, furniture can be arranged, partitions in the room can be easily changed, and a pattern can be changed. In addition to Western style, the living room, kitchen, living room, bedroom, etc. can be converted into each other, and the optimum function can be exerted each time according to changes in the family structure.

In conventional concrete houses, moisture, mold,
Although troubles occurred due to dew condensation, it also has the characteristics of maintaining a comfortable living environment by suppressing the growth of bacteria and the occurrence of mites by improving the heat insulating properties and improving the dew and moisture-proof properties.
