Mud obtained from nature is one of the oldest building materials in human history, along with stone and wood. Mud structures have the disadvantage of being weaker in durability compared to concrete structures, but have the advantage of being an eco-friendly material that is beneficial to the human body and has excellent temperature and humidity control capabilities. Therefore, in recent years, the use of clay as a material for residential buildings, such as residential houses, pensions, and villas, is increasing significantly.

In general, the construction method using mud can be divided into a masonry method, an overcoat method, and a compaction method. The masonry method is a method of building a wall by stacking pre-formed clay bricks one by one, and the layering method is a method of making a heartwood by weaving, for example, millet or bamboo, and attaching clay dough on both sides to form a wall. And the compaction method is a method of building a wall by filling the formwork with mud and drying it. In the past, the masonry method or the overcoat method, which is easy to construct, has been widely used, but recently, the compaction method with relatively high economic efficiency is mainly used.

At this time, the housing 31 may have a plurality of separate cavities for accommodating each reinforcing frame 10 independently as shown in FIGS. 4 and 5, and a plurality of reinforcing frames 10 together in one cavity. It may have an integrated cavity (not shown).

When the cavity is an integrated type, only one cavity may be formed in the housing 31 , or a plurality of cavities for accommodating a plurality of reinforcing frames 10 may be installed. For example, two integrated cavities accommodating four reinforcing frames 10 may be installed in one housing 31, or three integrated cavities accommodating three reinforcing frames 10 may be installed. . In such an integrated cavity, the clay dough is press-fitted with a separator plate or a separator (not shown) inserted between each reinforcing frame 10 so that the molded earth walls do not stick to each other.

Finally, the mud press-in means press-in the prepared mud dough into the cavity of the form module 30, and includes a mechanical extrusion device (not shown in the drawing) such as a conventional screw method or a piston method.

When the formwork module 30 is of the movable type 30a, the mud press-in means is bottom-up through the mud injection pipe 51 installed side by side on the fixed platform 20a as shown in FIGS. 2 and 4 . ), it is preferable to have a structure that fills the clay dough in the method. The mud injection pipe 51 enters from the side of the fixed platform 20a and may be branched side by side in plurality on the upper surface of the fixed platform 20a, that is, the loading surface on which the reinforcing frame 10 is erected.

And when the formwork module 30 is of the fixed type 30b, the mud press-in means is side-up through the mud injection pipe 52 installed on the side of the fixed platform 20a as shown in FIG. It is preferable to fill the clay dough in this way. Means for preventing drying of the mud may be additionally installed in the mud supply pipes 51 and 52 .

On the other hand, the accompanying Figure 6 shows a structure in which the platform 20 is a detachable platform 20c as a third embodiment of the present invention. The detachable platform (20c) has a structure in which the loading surface is separated into a plurality of pieces so that a plurality of soil walls formed on the loading surface can be separated and transported, respectively.

In addition, a platform deployment rail 42 that can be deployed by widening the gap between the platforms 20c is installed at the lower end of the detachable platform 20c, and the platform deployment rail 42 is installed on the bottom of the platform 20c. Rail wheels 22 moving along 42 are installed. It is preferable to install the movable formwork module 30b on the detachable platform 20c. And the detachable platform (20c) is separated in the longitudinal direction and the width direction so that the molded soil wall in the cavity can be transported independently, respectively.

Attached Fig. 6 shows a case in which the separate platform 20c is separated into six parallel structures, respectively. A platform deployment rail 42 capable of deploying the platforms 20c one by one in a direction orthogonal to the form transfer rail 41 is installed at the lower end of the split platform 20a, and the detachable platform 20c Rail wheels 22 that move along the platform deployment rail 42 are installed on the bottom surface, respectively.

The form transport rail 41 should not interfere with the movement of the detachable platform 20c moving along the platform deployment rail 42 , and the platform deployment rail 42 moves along the form transport rail 41 . It should not interfere with the movement of the formwork module (30a). The platform deployment rail 42 may be installed on both the left and right sides of the detachable platform 20c, or may be installed only on either one of the left and right sides. That is, the detachable platform 20c may be deployed in both left and right directions, or may be deployed in only one of the left and right directions.

At this time, the mud press-in means fills the mud dough through the mud injection hole 23 penetrating side by side in the detachable platform 20c. To this end, a mud supply pipe 51 is installed at the lower end of the separate platform 20c. The mud injection holes 23 are branched while passing through the inside of the platform 20c to form a plurality of mud injection holes 23 on the upper surface of the platform 20c. In addition, the mud supply pipe 51 has an elevating structure so as not to impede the movement of the detachable platform 20c. So, after all the mud dough is pressed into the cavity, the mud supply pipe 51 descends and is separated from the mud injection hole 23 of the platform 20c.

Between the separate platforms 20c, when the platform 20c is deployed along the platform deployment rail 42, a means for maintaining the left and right spacing between the respective platforms 20c constant, for example, a rope or chain for adjusting the spacing (shown in the figure). not) can be installed. The gap adjusting means holds the gap between each platform 20c so that it does not spread more than a certain distance. Therefore, when only the outermost platform 20c is deployed along the platform deployment rail 42, the rest of the platforms 20c are also deployed at regular intervals by the spacing adjusting means.

When the separate platform 20c is used, a plurality of earth walls are formed at once, and then, along the platform deployment rail 42, the interval between the earth walls loaded on each platform 20c is widened, thereby forming the earth wall. It can be dried more quickly, and as a result, productivity can be improved.

Hereinafter, the method for constructing a precast earthen wall according to the present invention will be described by dividing it into steps A) to F). First, in step A), two or more reinforcing frames 10 are erected side by side on the loading surface of the platform 20 .

At this time, it is preferable to cover both sides of the reinforcing frame 10 with a separator (not shown in the drawing) such as a large mesh or nonwoven fabric, cloth or vinyl sheet. The separator functions to prevent the mud from flowing out of the reinforcing frame 10, and further to prevent it from adhering to the frame side plate 33 on the side of the molded soil wall. The separator is separated and removed after the soil wall is molded, but the giant mesh may be left as it is.

In the next step C), a pair of frame side plates 33 installed inside the cavity are closely attached to both sides of the reinforcing frame 10 by using the side plate pressing part 34 provided in the formwork module 30 .

In the next step D), the cavity door 32 is closed and the clay dough is pressed into the cavity using the mud press-in means to form the earth wall including the reinforcing frame 10 . In step D), the mud dough may be press-injected in a bottom-up manner through the mud injection pipe 51 installed on the platform 20 , or the mud injection installed at the lower end of the side of the formwork module 30 . It is also possible to press-in the clay dough in a side-up manner through the tube 52 .

In addition, in the step C), the frame side plate 33 is moved only to a close position separated by a predetermined distance from the reinforcement frame 10, and in this state, the clay dough is pressed into the cavity according to the step D). Next, according to step C), the frame side plate 33 may be secondarily adhered to both sides of the reinforcing frame 10 . In this way, it is possible to more densely fill the clay dough inside the reinforcing frame 10 .

In the next step E), the frame side plate 33 is spaced apart from the earth wall by using the side plate pressing part 34, the cavity door 32 is opened, and then the platform 20 or the platform 20 using the transfer means. By moving the formwork module 30 , the soil wall is demolded from the formwork module 30 .

Finally, F) the soil wall loaded on the loading surface of the platform 20 is dried. Since the clay dough, which is the material of the soil wall, has high viscosity and plasticity, unlike the cement dough, the soil wall can be dried after the form is removed. At this time, the platform 20 may be developed by using the detachable platform 20c at predetermined intervals in the left and right directions, and then dried with hot air or naturally dried.

In the present invention, a plurality of reinforcing frames 10 are placed side by side on the fixed platform 20a in order, and the first earth wall is formed using the first reinforcing frame 10, and then the movable formwork module 30a is placed in two The soil wall can be continuously formed according to the same procedure while sequentially moving to the third and third reinforcing frames 10 . At this time, the first soil wall formed previously may be dried as it is on the platform 20a while the second and third soil walls are formed, or it may be dried by moving to another nearby place.
