Description

  The present invention relates to a soil wall molded body which is a porous sheet material, which is coated with a reinforcing material in a water-containing mixture of clay and fiber material, and then dried, and then dried, and a method for producing the same.

  The conventional construction of the earth wall is to create a paste-like water-containing mixture in which fibers are dispersed in clay containing a large amount of moisture, and this is fixed to the foundation supported by columns, studs, beams, bars, etc. by a so-called wet method. A method of coating to a thickness has been adopted. This construction method required a long period of time for the construction of the earth wall, including the drying period, because it needed to undergo the steps of undercoating, intermediate coating, and topcoating. Not only was the boundary surface of the overcoating easily peeled off, but the quality of the finished product depended on the skill of the engineer, and an expensive construction fee was inevitable.

At present, the base board is made of natural soil, silicon wall material mixed with chemicals, Otsu wall material, natural sand, crushed stone, clay, or those colored with synthetic resin. A soil wall panel has been filed in which a reinforcing material is applied to a coated material, a wooden frame, or a metal frame, and a soil wall is applied to attach the frame to the structure. However, there are disadvantages when combined with the original soil wall. It is far from the surface texture of the soft wall of ancient Japan that has been made for a long time. For example, a tea room constructed of earthen walls is the most suitable for enjoying the Japanese tea ceremony, which is a Japanese culture, and the covered earthen wall according to the present invention meets such requirements.

The problem to be solved is that the water-containing mixture of clay mixed with fiber material is difficult to form and handle as expected with conventional hand-painting and frame formation, and the density and overall strength are poor, and separation and peeling are difficult. It is an easy point.

The challenge to solve the problem

  The most important feature of the present invention is that a porous sheet material is encapsulated in a water-containing mixture of clay and fiber material, and a reinforcing material is encased and coated, and vibration, pressure and molding are performed.

The invention's effect

  The earth wall molded body of the present invention and the manufacturing method thereof include a porous sheet material in which a reinforcing material is encapsulated with a water-containing mixture of clay and fiber material and covered with a porous sheet material so that more fiber material is mixed into the clay. By suppressing the fiber material with vibration and pressurizing it, the adhesion between the clay and the fiber material is also improved by the pressure, the clay particles are pushed out to the porous sheet material, the surface density is also suppressed by suppressing the particles It can be manufactured in a short time by forming a lightweight earth wall molding with improved separation and separation and artificially drying it.

  The clay wall molded body is made of clay, which is difficult to coat, and the porous sheet material covers the water-containing mixture and reinforcing material mixed with more fiber materials, making it easier to handle the water-containing mixture and making the specified shape porous. By wrapping with a sheet material, the overall strength is high, separation and peeling are reduced, and handling of the earth wall molding is easy.

The perspective view of an example which included the water-containing mixture and the reinforcing material in the framework, and covered and formed it with the porous sheet material.

  This porous sheet material is made by mixing a large amount of fiber material with clay to make a water-containing mixture, laying on the porous sheet material as a lower layer, embedding a reinforcing material thereon, and further laying on it as an upper layer. After coating, the water-containing mixture improves the adhesion between clay and fiber material by pressure by vibration and pressurization, and the clay particles are pushed out into the porous water passage, and the density of the surface is reduced by suppressing the particles. As a result, the inner wall and the surface are further integrated to form a soil wall molded body without separation and peeling. The stitches and weaves of the porous material are preferably around 3 mm to 1 cm, and the porous sheet material such as cloth, wire mesh, and resin can be peeled off after being molded or dried.

  In a manufacturing method in which a porous sheet material of a predetermined shape encapsulates and coats a water-containing mixture of clay and fiber material with a reinforcing material, and then vibrates, pressurizes, and molds, a lot of plant fibers are mixed into the clay, for example By covering the water-containing mixture and reinforcing material mixed with a lot of reeds, reeds, dokudami, genokosho, psyllium, etc. with a porous sheet material, the fiber material is suppressed and vibration and pressure are applied to further adhere the clay and the fiber material. The clay particles are extruded into the porous water passage holes, and by suppressing the particles, a clay wall molded body whose entire surface is covered with the porous sheet material is formed. Since this soil wall molded body contains a lot of plant fibers, it is possible to produce a soil wall molded body having a light weight as a whole, heat retaining properties and bactericidal properties, and without separation and peeling. Furthermore, the manufacturing method in which the water-containing mixture and the reinforcing material are encapsulated in a bag of a porous sheet of a predetermined shape, and this is vibrated and pressurized can easily be made in various forms, and a dense earth wall molded body can be manufactured. I can do it.

  The molding in the frame of claim 5 is impaired by making a water-containing mixture of clay and fiber material, covering the porous sheet material with a reinforcing material in the water-containing mixture, and vibrating and pressurizing in a frame of a predetermined shape. It can be molded into a predetermined shape without any problems. The vibration method is manually hitting or suppressing the frame or mechanical vibration. The pressurization is tapping or suppressing from the upper surface, or vibration or pressurization with a mechanical roller or a press.

  A water-containing mixture of clay and fiber material is laid as a lower layer from the opening of the frame with the entire periphery and bottom closed in FIG. 6, and a reinforcing material is buried on it and further a water-containing mixture is laid thereon as an upper layer. Furthermore, it is a manufacturing method in which only the upper surface is coated, in which the upper surface is coated with a porous material, and then vibration, pressure, and molding are performed.

  The lattice material shown in FIG. 3 of the reinforcing material is a natural material combined in a 50 cm × 10 cm square. Or a perforated thin plate, grid, net or bar, all of which are natural or metal, synthetic, or resin material to prevent separation and peeling of the lower layer and upper layer, or to maintain the strength of the earth wall body and to reinforce it. It becomes a brute force for joining to the structure.

  Drying by drying the molded earth wall molded body is preferably artificial drying for about 5 to 8 hours for a 60 cm × 1,800 cm 6 cm thick earth wall molded body. The dried earth wall molded body can be used by a method such as fitting, attaching, pasting, laying or stacking to a structure.

  The earth wall molding is not only used as a building material to fit, attach, paste, lay or pile on the structure, but also as a work to obtain harmony and symbiosis with the natural world because it is molded by a drying process without firing natural materials. Art, artistic and art that can be felt in For example, soil tapestry, soil furniture, soil bed, soil vase, etc.
