Description

The present invention relates to a soil wall structure of a house.

Old houses were made of wood, soil, and paper, and they were highly breathable, but recently, the wooden structure has changed from an aluminum sash, and the wall structure has changed from soil to a new building material. Highly confidential housing has been created. However, in the humid climate of Japan, it can cause condensation and mold, and organic gas generation from new building materials and furniture can contaminate the interior, resulting in chemical hypersensitivity such as atopy, asthma, and hay fever. There is an increasing number of people in need.

  Considering the Japanese climate, it is most desirable to make the enclosure out of breathable wall materials as in the past, but to apply the wall material, a Komai foundation knitted like a net beside the bamboo fence is required. To do. However, most of the craftsmen are aged, and the number of sites required for technology transfer is drastically reduced, making it difficult to transfer, and securing space and storage space on the site that asks for rough walls that require large amounts of mud. However, it is difficult to implement due to problems with the construction period such as the drying period.

  In today's houses, gypsum board is used for the housing of the interior wall, but it is difficult to treat as industrial waste, and organic gas is generated if it is buried without burning, and it is regarded as a troublesome material that pollutes the environment. ing.

  In Patent Document 1, as a base material that replaces the bamboo Komai base material, a large number of holes are formed in a plywood plywood, and wall materials are applied to both sides to solve the problem.

  If this method is used, the groundwork equivalent to Takekomai does not require a specialized craftsman, and it is said that the construction is easy without changing from a conventional plasterboard.

  In the case of Patent Document 2, it is fixed by using a member attached to a punching plate from a conventional method in which bamboo is tied with a string or a vinyl string at a certain interval next to the fence to form a Komai foundation. A base material equivalent to the bamboo Komai base knitted with a rope is formed by attaching a member for holding a horizontal member at an interval of and inserting bamboo.

  Using this method, it is said that it does not require specialized craftsmen and can be made stronger and more uniform than bamboo knives knitted with individual ropes.

  In Patent Document 1, a myriad of holes are made in a veneer plywood so that the conditions are the same as that of a bamboo Komai foundation. In this case, the moisture on the painted wall, which is a wet method, causes the plywood to expand, The paint wall oozes out and causes uneven color, and the plywood shrinks during drying, which may cause the paint wall to peel off or crack.

  In the case of Patent Document 2, a conventional bamboo is constructed by fixing a bamboo to a fence with a member inserted into a punching board, attaching a cross member holding member at a fixed interval, and constructing a bamboo small dance by passing or sandwiching the bamboo in that part. Although it is the same as the Komai foundation, in this case, the space where the bamboo and bamboo are knitted in a cross is 30mm to 40mm, and for that purpose, the rough wall soil with coarse particles is applied on one side and dried. In this method, the back side and the front side are integrated by applying rough wall soil to the back side again. For this reason, the wall material has a thickness of 60mm to 80mm, including the finish coating. Considering the internal space, it must be positioned between the pillars. However, in the current construction method with many Western-style houses, pillars enter the wall and make a continuous large wall.

  In Patent Documents 1 and 2, it is a conventional rough wall system that is constructed by applying mud, and as mentioned above, the space for kneading mud is long and the storage period is long, and it takes half to one month to dry the rough wall. There are too many problems in view of the current housing situation. Therefore, we will improve the bamboo Komai base, create a base that can be lightly coated, and develop a method to reduce the thickness of the earth wall to less than half.

  The earth wall of the present invention is a net bamboo Komai comprising a wall structure, a plurality of core members arranged in the lateral direction of the wall fixed to the structure, and a net placed on the core material. A wall material is bitten into the net stitch and is applied.

  Since the net is arranged on a plurality of core materials and the wall material is applied, the wall material bites into the net, the strength of adhesion is increased, and peeling is unlikely to occur. In addition, net Komai made by using a net-like sheet made of glass fiber or the like so as to sandwich bamboo in the horizontal direction does not require vertical bamboo, and the thickness of the intersecting portion is reduced. Thus, the thickness can be reduced to one-half the thickness of the conventional bamboo Komai foundation.

  Installation can be done with screws just like other building materials, so construction is easy. Also, the framework of the mounting base such as plasterboard is the same as before, and there is no need to change it.

  In addition, it is no longer necessary to knit bamboo with ropes, and there is no need for specialized bamboo craftsman craftsmen, which can be installed by carpenters, plasterers and workers, eliminating the aging and inheritance problems of professionals Is done.

  The soil coating thickness is less than half, the drying period is shortened, the construction period is shortened, and the problem of bringing a large amount of mud into the field is also eliminated.

The figure which shows the other Example of the net bamboo Komai of this invention. EE sectional view showing another embodiment of the net bamboo Komai of the present invention

    Using bamboo nets made of hemp or glass fiber as a method to eliminate vertical bamboo, bamboo is laid continuously at a certain interval in the horizontal direction from bamboo Komai foundation that crosses vertical bamboo and horizontal bamboo and knits with rope. A net bamboo Komai foundation shaped like a sudare can be constructed by either inserting it or using multiple nets to fix the bamboo between the back and front.

  FIG. 1A shows an example of a clay wall of the present invention. The net Takeki Mai 1 is configured by arranging a bamboo 12 as a core material on a net 11 horizontally, and providing a plurality of them vertically. The net 11 is made of glass-filled resin fibers, and a rectangular or circular one having a size of 100 to 500 grams per square meter, preferably 150 to 200 grams and a stitch size of 10 to 20 mm on a side is used. The bamboo 12 is used in an elongated shape that is vertically split into 4 to 60% and has a width of 15 to 50 mm, preferably 20 to 35 mm. A cut is made in a part of the net 11, and the bamboo 12 is sewed to the cut. FIG. 1B is a cross-sectional view showing the AA cross section of FIG. 1A, and shows a state where a plurality of bamboos 12 are attached to the net 11. A mounting interval H (shown in FIG. 1A) of the plurality of bamboos 12 is 16 to 60 mm, and a screw (not shown) is used for a screw hole 13 provided in the bamboo 12 to connect the net 11 and the bamboo 12. And fix.

  The stitch shape of the net 11 can be not only a rectangle but also other polygons. Further, the bamboo 12 can be sandwiched between the two nets 11, and the pitch size of the nets of the two nets can be made rougher on the indoor coating surface and finer on the outdoor side.

  FIG. 2 shows a frame 2 of a wall to which the net bamboo wood dance of the present invention is attached. A pillar 4 is provided between a ceiling 6 and a floor 5 of the building, and a spacer 21 is provided between the pillars 4. Reference numerals 22 and 23 denote crosspieces for preventing the generation of a gap due to contraction of the wall material.

FIG. 3 shows a state in which the bamboo 12 is attached to the framework 2 shown in FIG. 2. The bamboo 12 is attached horizontally across the stud 21. Since the figure is difficult to understand, the description of the net is omitted, and the attachment of the net is shown in FIG.
FIG. 4 is an enlarged view of the BB cross section of FIG. 3. The bamboo 12 is attached to the pier 22 with screws 14, and the wall material is a wall material so as to cover the bamboo 12 and the net 11 attached to the bamboo 12. 7 is applied. The wall material 7 penetrates between the meshes of the net 11 and bites into the net 11, thereby strengthening the connection.
The weight of the wall material is the bamboo 12 via the net 11, and the bamboo 12 is further fixed and supported by the spacer 21.

Since the wall material 7 has air permeability, natural air can be ventilated from X to Y shown in the figure.
FIG. 5 shows a state before the net Takeki Mai 1 is installed in a building, and the net 11 and the bamboo 12 can be wound together like a suddle with the net 11 and the bamboo 12 fixed together. For this reason, Mai Takeki can be manufactured in advance, not only shortening the work time on site, but also easy to store and carry in.
FIG. 6 shows the state of the end face of the net 11. The top end 11 a of the net 11 is bent and wound around the bamboo 12, and fixed with a fastener 15, thereby fixing the net 11 and the bamboo 12 more firmly. Yes.
FIG. 7 is an enlarged view of the CC cross section of FIG. 3. The bamboo 12 fixed to the stud 21 and the net 11 are attached with screws 14, and the wall material 7 is attached so as to cover the bamboo 1. It is applied.
FIG. 8A is a view showing another embodiment of the state in which the bamboo 11 and the net 12 are fixed, and FIG. 8B is a sectional view taken along the line DD in FIG. 8A. As shown in the figure, the bamboo 12 is sandwiched between the nets 11 and fixed with fasteners 15. In this way, the bamboo 11 can be attached to the net without being sandwiched between the nets, and the net 11 can be attached to the surface.

  FIG. 9 is a diagram showing another embodiment of the present invention, and two nets 11b and 11c are provided so as to sandwich the bamboo 12, thereby constituting a net bamboo komai 1a. The net on the painted surface (inside the room) has a coarse mesh, and the net on the back (outside) has a fine mesh. FIG. 10 is an enlarged view of the EE cross section of FIG. If it does in this way, a wall material will be extruded from a net | network inside, and a wall material will be pressed against a net | network on the outside, and adhesiveness will improve.

  The shape of the net bamboo Komai of the present invention is 1,800 mm in length and 900 mm in width, which is the same size as a gypsum board, etc., but it can be made in a free size for large walls.

  In conventional soil walls, the thickness of the soil was sufficient to obtain a heat insulation effect and a humidity control effect. However, as a soil development that exhibits the same effect even with thin coating, the dried clay is crushed to 3 mm to 15 mm or less. Further, 20% to 50% of a natural material diatomaceous earth having a heat insulation function and a humidity control ability that are several steps higher than ordinary soil is mixed to make a high functional soil and used for the wall material of the present invention.

  In addition, the developed soil is highly viscous soil, and in the case of highly viscous soil, until now, sand and straw were mixed to adjust the clay of the soil and used for primer, etc. The clay is not adjusted using sand, and is adjusted by a method that mixes 3 to 5 times or more of the chopped soot that is finely cut into 5 mm to 20 mm.

  Since the developed soil is in a bag and brought in as much as necessary, the site is not polluted and storage space is not required, making it possible to realize full-scale dwelling in all houses such as small sites and cities.

  The conventional bamboo Komai foundation is knitted by crossing the bamboo vertically and horizontally, but the diameter of the stitch is 30mm to 40mm, and in the case of fine molecular soil it falls out of the hole, It is necessary to apply a long coat to make it thick. In the case of Bamboo Komai Net, the interval between the bamboo and the bamboo is connected by the net, and even if the painted soil is pushed out from the gap between the bamboo, it does not fall and adheres to the net. Thin coating with use becomes possible. Therefore, a large wall structure is constructed with little effect on the internal space.

  The groundwork such as plasterboard does not have air permeability and is not suitable as a groundwork groundwork. In the case of the net bamboo Komai foundation, the breathing function is exhibited freely from the front and back, and a soil wall that makes use of the breathability unique to soil can be constructed.

In the case of a traditional bamboo Komai foundation, use a coarse grained soil sampled from a mountain or the like, and apply a long-legged heel and soil kneaded with water to one side of the wall. When it has been naturally dried and hardened for 20 to 30 days or more from the date of application, it is finally possible to apply a similar soil to the back side and dry it to form a wall foundation. The net bamboo Komai of the present invention significantly shortens the construction period by a thin coating method only for surface construction.
In the examples, bamboo 12 was used as the core material, but wood, plastic, or metal may be used. The net 11 may be made of natural material such as hemp or straw, in addition to glass-filled resin fibers, Metals may be used, and carbon fibers may be mixed.
Moreover, when the direction of the fiber of the net | network of 11 is diagonally provided with respect to the stud 21, the structure of a wall can be strengthened.
