Description

Composite earth wall with insulation function and construction method {A composite of complex earth wall with insulation}

The present invention relates to a construction method and a composite soil wall of the composite soil wall, to take advantage of the deodorization effect, moisture absorption and moisture absorption function, temperature and humidity control, etc. of the soil and to compensate for the weak point to the external environment or load and The double-walled structure of the internal soil wall mainly composed of gravel and the external soil wall composed mainly of clay and quicklime was formed. Also, to solve the dissatisfaction with the living environment of people living in the earth house due to the low thermal insulation performance The present invention relates to a method for constructing a composite soil wall and a composite soil wall that can satisfy thermal conductivity or thermal permeability according to the design standard by inserting insulation materials such as styrofoam, rice straw, rice hull and sawdust between the interior and exterior soil walls.

Korean architectural culture is not only an exaggeration to say that it is a construction using soil and wood. Among them, the soil is the main material of the building, and serves as a structure of the building and a functional role of deodorizing effect, moisture absorption and moisture absorption, and temperature and humidity control. In addition, since most modern people live more than 90% of the indoor space, the interest on the environment-friendly earthen building continues to increase due to the increasing impact on the environmental pollution and energy consumption of existing concrete buildings. Various construction methods have been studied to secure a stable structure during construction, and when used as a building material, problems such as strength problems due to dispersibility, poor insulation, and poor thermal insulation problems have been solved. In other words, the soil material is not a substance composed of a single compound but a mixture of various substances, so it uses natural soil as it is. There is a disadvantage in that it is easily dispersed by physical and chemical action such as damage to the outer wall. In addition, general soil has a low thermal insulation because the thermal conductivity is 0.2823W / mK, so when the building is constructed using the soil compaction method, the insulation is inferior to that of a concrete building. There is a disadvantage of increasing, because the cohesive force between the soil composition is weak, there is a limit that can not be used as the main material for the construction of high-rise buildings because the strength of the soil is low.

As a conventional soil construction method, a soil compaction method and a soil placing method are widely used. The soil compaction method is a method of increasing the stability of soil structures by applying pressure while stacking the soil, and the soil placing method is a method of pouring a liquid soil composition like concrete using formwork to facilitate construction. There is an advantage. In the United States, we have been successful in the commercialization of earthen houses by devising new methods of using soil for construction. Especially, the earthen wall has a thickness of about 40cm by using the compaction method and secures the stability of the building. It is at a costly level. In Korea, as in the United States, the construction of soil buildings is carried out using the above techniques, but it is about environmentally friendly finishing materials or substructures using soil, and there is no advanced technology for the walls that make up the structure. It is impossible to make use of the characteristics of each method by applying each method such as soil casting method collectively.

Accordingly, the conventional technology for soil construction satisfies the structural stability suitable for modern construction when constructing environment-friendly buildings using soil, satisfies the functions such as deodorization effect, moisture absorption and moisture absorption function, and temperature and humidity control, and construction method is easy. Soil construction methods that satisfy both the saving of building costs and the like are required.

 The present invention is designed to solve the problems of the prior art as described above by inserting a heat insulator into the existing soil wall is constructed only as a soil composition to improve the heat insulation of the soil building, to satisfy the above heat insulation and structural stability We present the construction method and structure of the composite wall which solves the problem that the soil wall generally has a thickness of 94cm or more by using the composite soil wall. In addition, it is possible to obtain the effect of distinguishing the inner and outer soil walls by applying the composite soil wall, so that the inner soil wall can give the deodorizing effect, moisture absorption and moisture damping function, temperature and humidity control function, etc. The problem to be solved by the present invention is to propose a construction method and structure of a composite wall having a solution to the external environment such as oxidation of the outer wall due to the oxide material and damage to the outer wall due to moisture and problems of soil strength.

In the construction method and composite soil wall construction method of the present invention for solving the above problems, in the group consisting of styrofoam, rice straw, rice husk and sawdust and installed a heat insulating material receiving member having an interval of 5 ~ 15cm of internal storage space Filling at least one selected heat insulating material into the heat insulating material receiving member; Installing a long-walled iron in the form of a lattice with a thickness of 50 to 100 cm through and supporting the inner and outer soil walls by penetrating the insulation member filled with the insulation; Installing an inner mud wall formwork at intervals of 5 to 15 cm from one side of the insulation member and installing an outer mud wall formwork at intervals of 15 to 20 cm from the other side of the insulation member; Filling the soil composition with a soil compaction method inside the installed interior soil wall formwork, and filling the soil composition with the soil casting method inside the installed exterior soil wall formwork to form internal and external soil walls; Characterized in that it comprises the step of removing the inner, outer soil wall formwork from the inner, outer soil wall formed.

The present invention relates to the construction method of the composite soil wall and the composite soil wall by using the soil compaction method to construct the interior soil wall made of clay and clay such as clay (clay) or silt (silt), deodorizing performance, moisture absorption It performs the unique functions of soil such as function, temperature and humidity control function, and indoor air purification, and uses the soil pouring method to construct the external soil wall made of clay and lime, so that the external wall is oxidized by the oxide of the air and Securing durability against external environment such as damage and constructing only with soil compaction wall has the effect of solving the problem of strength that wall thickness should generally have more than 94cm by using such external soil wall as bearing wall. In addition, the insulation material is inserted between the inner and outer soil walls to obtain insulation effect. The long iron is inserted to realize the effect that the inner and outer soil walls are integrated without being separated from each other.

Hereinafter, the construction method and the composite soil wall of the composite soil wall of the present invention will be described in detail with reference to the drawings.

1 is a perspective view of a composite soil wall manufactured by the construction method of the composite soil wall according to the present invention, Figure 2 is a longitudinal cross-sectional view of the AB line during the construction process of the composite soil wall according to the present invention, Figure 3 is a composite according to the present invention The cross section of the CD line is shown during the construction of the soil wall.

As shown, the construction method of the composite earth wall according to the present invention is one type selected from the group consisting of styrofoam, rice straw, rice husk and sawdust and installing a heat insulating material receiving member 14 having an interval of 5-15 cm of internal storage space. Filling the above heat insulating material 13 in the heat insulating material receiving member 14; Step of installing the long iron 10 to support the interior and the external soil wall (12, 11) and support each other through the insulating material receiving member 14 filled with the insulating material 13 in a grid form of 50 ~ 100cm intervals ; Install the inner soil wall formwork 16 at intervals of 5 to 15 cm from one side of the insulation member 14 and the outer soil wall formwork at intervals of 15 to 20 cm from the other side of the insulation member 14. Installing 15; Filling the soil composition by the soil compaction method inside the installed inner soil wall formwork 16, and filling the soil composition by the soil casting method inside the installed outer soil wall formwork (15) , 11); And removing the inner and outer soil wall molds 16 and 15 from the inner and outer soil walls 12 and 11 formed thereon.
Clay (clay) or silt (silt) 20 ~ 40wt%, sand or gravel aggregate of 60 ~ 80wt% in the soil wall formwork 16 to add 5 to 20wt% of water to the soil composition The soil composition is filled with a soil compaction method to form an inner soil wall 12, and the soil is mixed with 50 to 95 wt% of clay, 5 to 50 wt% of slaked lime or quicklime in the outer soil wall formwork 15. The soil composition to which 5 to 50 wt% of water is added to the composition is filled by a soil pouring method to form an external soil wall (11).

First, the soil wall of the prior art has a low thermal insulation performance (thermal conductivity of 0.2823W / mK), so that the wall constructed only by the soil compaction method does not satisfy the residential environment of people living in the soil house, and has a thickness of approximately 94 cm. There is a problem in that construction difficulties and high construction costs occur. Therefore, the present invention uses the structure of inserting the heat insulating material 13 between the mud wall and the composition of the inner mud wall 12 and the outer mud wall 11, the inner mud wall 5 ~ 15 cm, the insulation 5 ~ 15 cm, The external soil wall 15 ~ 20cm and has a wall thickness of up to 50cm as a whole solves the above problems. In other words, the internal soil wall 12 utilizes a composition capable of keeping the internal environment comfortable by utilizing the deodorizing effect, moisture absorption and moisture absorption function, and temperature / humidity control function, which are inherent in the soil, and the external wall is durable against an external environment that is insufficient only by the internal wall. In order to solve the problem of securing and soil strength, formwork is divided into internal and external soil walls (12, 11), and the insulation material 13 inserted between the sheep walls is installed to improve the thermal insulation performance.

In order to solve the above problems by first securing a space in which the heat insulating material 13 can be installed between the inner and outer soil walls 11 in advance to solve the problem that the heat insulating material 13 is deformed or damaged after completion of construction, According to the purpose of the earthen building and the characteristics of the area, there is an advantage that the type of the heat insulating material 13 can be conveniently changed. Also, the heat insulating material 13 can be inserted before the compaction, and the insertion space of the heat insulating material 13 is secured. In order to install a heat insulating material receiving member 14 to a thickness of 5 ~ 15cm. Compared with the earth wall constructed using only the soil composition by the soil compaction method by filling the heat insulating material containing the one or more selected from the group consisting of styrofoam, rice straw, rice husk and sawdust to the installed heat insulating material receiving member (14). There is an advantage that can provide improved thermal insulation.

In addition, the step of installing a long iron 10 to support the inner and outer soil walls (12, 11) and support each other through the insulating material receiving member 14 filled with the insulating material 13 in a grid form of 50 ~ 100cm intervals to be. Concavities and convexities are formed in a portion where the long iron 10 is connected to the inner and outer soil walls 12 and 11. If the interior and exterior soil wall formwork (16, 15) is removed after completion of the construction of the soil wall without installing the long iron (10), the insulation material (13) inserted before the compaction is deformed, and the compacted and poured soil wall is dried. Since there is a heat insulator 13 there is a problem that the two earth walls are spaced apart from each other. This process is characterized in that the mud wall is integrated and the insulation material 13 is installed so that there is no deformation of the insulation material after the insulation is inserted 50 ~ 100cm intervals so that the mud wall is integrated without being spaced apart from each other.

Next, the inner soil wall formwork 16 is installed at intervals of 5 to 15 cm from one side of the heat insulating material accommodating member 14 in which the long iron wire is installed, and 15 to 20 cm from the other side of the heat insulating material accommodating member 14. Steps to install the outer soil wall formwork 15 at intervals. Clay soil or silt (silt) is 20 ~ 40wt%, sand or gravel aggregate 60 ~ 80wt% in the soil wall form 16 installed in the soil composition 5-20wt% of water added to the soil composition A soil composition is filled with a soil compaction method to form an inner soil wall 12, and the soil is mixed with 50 to 95 wt% of clay, 5 to 50 wt% of clay, or quicklime to the outer soil wall formwork 15. Filling the earth composition 5 ~ 50wt% of the soil composition to the composition by the earth casting method to form an external soil wall (11). In the method of constructing the interior soil wall 12 using the soil compaction method, it is important to mix the soil wall at a composition ratio that satisfies the compressive strength while maintaining the soil intrinsic characteristics, such as clay (clay) or silt (silt). The higher the composition ratio of soil, the higher the viscosity of the soil composition. The higher the composition ratio of the aggregate, the more dispersed it was in the form of powder. The continuous compressive strength was achieved when the composition was 30: 70wt% and the moisture content was 9wt%. Indicates the effect of the increase.

In addition, the external soil wall (11) is a clay composition mixed with clay 50 ~ 95wt%, hydrated lime or quicklime 5 ~ 50wt% of the earth composition by adding 5 ~ 50wt% of water to the soil composition by the soil casting method The wall 11 is formed. At this time, the clay has good expandability, absorbs water up to 5 times its own weight, and can be mixed with hydrated lime or quicklime to create a wall that does not penetrate water. In addition, since the density is much higher than that of loess, clay such as bentonite has the density of 0.4 ~ 0.9cm which is 100 times denser than the 30cm of loess. Securing the durability of the external environment such as damage and construction with soil compaction wall alone solved the problem of strength that the wall thickness should generally be 94cm or more to a thickness of up to 50cm.

The following is a comparative test of the compressive strength of the embodiment of the composite soil wall consisting of the present invention and the comparative example produced by the soil compaction method and the soil placing method of the known technology. Moreover, this does not limit the specific implementation of the present invention.
