More specifically, the soil wall used to construct a mud building can be mass-produced in a precast manner. A new soil wall forming system and a method of constructing a precast soil wall using the same.

Mud from nature, along with stone and wood, is one of the oldest building materials in human history. Mud building has the disadvantage of weak durability compared to concrete building, but has the advantage of excellent temperature and humidity control ability and environmentally friendly material that is beneficial to the human body. Recently, the use of mud as a material for residential buildings such as homes, pensions and villas has been increasing.

In general, building construction methods using mud can be divided into masonry, painting, and compaction. The masonry method is to build a wall by stacking the pre-molded soil bricks one by one, and the overcoat method is to form a core by weaving a millet, bamboo, etc., and attaching mud dough on both sides to form a wall. And the compaction method is a method of building the wall by filling the mold with mud and drying it. In the past, a lot of painting methods and easy coating methods have been used, but recently, a relatively economical compaction method is mainly used.

When the platform 20 is a fixed type (20a), the transfer means 30 is a side of the fixed platform (20a) along the longitudinal direction along the transfer rail 41 and the bottom of the movable formwork module (30a) Consists of rail wheels 35 installed in. And if the formwork module 30 is a fixed type (30b), the transfer means 30 is composed of a transfer wheel 21 installed at the bottom of the movable platform (20b). Unlike the rail wheel 35, the transfer wheel 21 does not need to install a transfer rail 41.

In the present invention, the rail wheel 35 is installed at the bottom of the movable formwork module 30a for convenience, and the transfer wheel 21 is installed at the bottom of the movable platform 20b, but on the contrary, the movable formwork module ( The transfer wheel may be installed at the lower end of 30a), and the transfer rail and the rail wheel may be installed at the lower end of the movable platform 20b.

On the other hand, the transfer means 30 may be a platform transport vehicle (not shown in the drawing) specially made to load the platform 20. By using such a platform transport vehicle, the molded soil wall can be quickly moved and spread to a large place for easy drying and storage. To this end, the platform carrying vehicle may be installed with a crane that can get off the platform 20 on which the soil wall is loaded.

Next, the formwork module 30 includes a housing 31, a cavity door 32, a frame side plate 33, and a side plate pressing portion 34. And the movable formwork module 30a according to the first embodiment of the present invention is provided with a rail wheel 35 in the lower portion of the housing 31, the fixed formwork module 30b according to the second embodiment of the present invention. The lower part of the housing 31 is fixed to the ground.

The frame side plate 33 may be supported by the side plate pressing portion 34. Separate support means may be provided.

The formwork module 30 accommodates a plurality of reinforcing frames 10 side by side in parallel in one housing 31, for example, a plurality of soil walls corresponding to each reinforcing frame 10 at the same time. It can be configured to mold. In this case, the housing 31 may have a plurality of separate cavities for accommodating each reinforcing frame 10 independently, as shown in Figures 4 and 5, and accommodates a plurality of reinforcing frame 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, and a plurality of cavities accommodating a plurality of reinforcing frames 10 may be installed. For example, two integrated cavities for receiving four reinforcement frames 10 may be installed in one housing 31, or three integrated cavities for receiving three reinforcement frames 10 may be provided. . In such an integrated cavity, the mud dough is press-fitted in a state in which a separator plate or a separator (not shown) is inserted between the respective reinforcing frameworks 10 so that the molded soil walls do not stick together.

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

When the formwork module 30 is a movable type (30a), the mud injection means is bottom-up (bottom-up) through the mud injection pipe 51 is installed side by side on the fixed platform (20a) as shown in Figs. It is preferable to have a structure for filling the mud dough in the) method. The mud injection pipe 51 may enter from the side of the fixed platform (20a) can be branched side by side in the upper surface of the fixed platform (20a), that is, the loading surface on which the reinforcing frame (10) is standing.

And if the formwork module 30 is a fixed type (30b), the mud pressing means is a side-up (side-up) through the mud injection pipe 52 is installed on the side of the fixed platform (20a) as shown in FIG. It is desirable to fill the mud dough in a manner. The mud supply pipe (51, 52) may be further provided with means for preventing the drying of the mud.

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

In addition, a platform deployment rail 42 is installed at a lower end of the detachable platform 20c to spread the space between the platforms 20c to the side, and the platform deployment rail is disposed on the bottom of the platform 20c. The rail wheel 22 which moves along 42 is provided. It is preferable to install the movable formwork module 30b on the detachable platform 20c. The detachable platform 20c is separated from each other in the longitudinal direction and the width direction so as to independently transport the soil wall formed in the cavity.

6 illustrates a case where the detachable platform 20c is separated into six parallel structures. At the lower end of the detachable platform 20a, a platform deploying rail 42 capable of deploying the platform 20c one by one in a direction orthogonal to the formwork conveying rail 41 is installed. The bottom wheels 22 are provided with rail wheels 22 moving along the platform deployment rails 42, respectively.

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

At this time, the mud pressing means fills the mud dough through the mud injection hole 23 penetrated side by side in the detachable platform (20c). To this end, a mud supply pipe 51 is installed at the lower end of the detachable platform 20c. The mud injection hole 23 branches 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. And the mud supply pipe 51 is made of a lifting structure so as not to interfere with the movement of the detachable platform (20c). Thus, after all the mud dough is pressed into the cavity, the mud supply pipe 51 is lowered and separated from the mud injection hole 23 of the platform 20c.

Means for maintaining a constant left and right spacing between each platform 20c when the platform 20c is deployed along the platform deployment rail 42 between the detachable platform 20c, such as a gap adjusting rope or chain (not shown). May not be installed). The gap adjusting means is to hold the gap between each platform (20c) does not open more than a certain distance. Thus, if only the platform 20c located at the outermost side along the platform deployment rail 42 is deployed, all the other platforms 20c are also deployed at regular intervals by the gap adjusting means.

When the detachable platform 20c is used, the soil wall is formed by forming a plurality of soil walls at once, and then widening the space between the soil walls loaded on each platform 20c along the platform deployment rail 42. It can dry more quickly and as a result, productivity can be improved.

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

In the next step B), the platform 20 or the formwork module 30 is moved using the transfer means 30 so that the reinforcing frame 10 erected on the platform 20 enters the cavity of the formwork module 30. Move it. When the platform 20 is a fixed type 20a, the formwork module 30a is moved, and when the formwork module 30 is the fixed type 30b, the platform 20b is moved.

At this time, it is preferable that both surfaces of the reinforcing frame 10 cover a separator (not shown in the drawing) such as a net, a nonwoven fabric, a cloth, or a vinyl sheet. The separator prevents mud from flowing out of the reinforcing frame 10 and further prevents the mud from sticking to the frame side plate 33 on the side of the molded soil wall. The separator may be separated and removed after the soil wall is formed, but the net may be left as it is.

In the next step C), the pair of frame side plates 33 installed inside the cavity are in close contact with 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), close the cavity door 32 and press the mud dough into the cavity using the mud pressing means to form an earth wall including the reinforcing frame 10. In the step D), the mud dough may be press-fitted in a bottom-up manner through the mud injection pipe 51 installed on the platform 20, and mud injection may be installed at the lower side of the form module 30. The mud dough may be press-fitted in a side-up manner through the pipe 52.

Further, in step C), the frame side plate 33 is first moved only to a proximal position spaced apart from the reinforcement frame 10 by a predetermined distance, and in this state, the mud dough is press-fitted into the cavity according to the step D). Next, again according to the step C) may be in close contact with the frame side plate 33 on both sides of the reinforcing frame (10). In this way, the mud dough can be more densely packed in the reinforcing frame 10.

In step E), the side plate pressing part 34 is used to separate the frame side plate 33 from the soil wall, the cavity door 32 is opened, and then the platform 20 or the The formwork module 30 is moved to demould the soil wall from the formwork module 30.

F) Finally, the soil wall loaded on the loading surface of the platform 20 is dried. Mud dough, which is a material of the soil wall, has high viscosity and plasticity, and thus, unlike cement dough, the soil wall may be dried after removing the formwork. In this case, the platform 20 may be developed by a predetermined interval in the left and right directions by using the detachable platform 20c at a predetermined interval, and then hot air dried or naturally dried.

In the present invention, a plurality of reinforcing frame 10 is placed side by side on the fixed platform (20a) in order, and after forming the first soil wall by using the first reinforcing frame (10), two of the movable formwork module (30a) By moving sequentially to the third and third reinforcement frame 10, it is possible to continuously form the soil wall according to the same procedure. In this case, the first soil wall formed beforehand may be dried as it is on the platform 20a while the second and third soil walls are formed, or may be moved to another place nearby and dried.
