Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is related to hygiene room units such as bathroom units and toilet units. This relates to a device having a characteristic in the structure of the side wall.

0002 [Problems to be solved by conventional techniques and ideas] Traditionally, tile panels and steel sheet panels have been used as side wall construction materials in bathroom units, etc. A composite panel in which foam is sandwiched between thin metal plates on both sides, Furthermore, various materials such as calcium silicate plates are used, but these are all structurally It also had various problems such as a complicated manufacturing process and high cost.

0003 For example, in the case of a tile panel, a metal frame 100 is used as shown in FIG. After assembling the base board 102, the base board 102 is fixed with adhesive, and a large number of A process of pasting the tiles 104 in a predetermined arrangement is required, which is structurally and manufacturingly difficult. It was relatively complex and costly.

0004 Also, in the case of steel plate panels, the edges are bent for reinforcement etc. It requires many manufacturing steps and costs such as attaching plasterboard and plasterboard. It also becomes more expensive.

[0005] Furthermore, in the case of a composite panel in which the foam is sandwiched between thin metal plates, the panel There are many components, and the process requires filling foam between a pair of thin metal plates. It requires a lot of man-hours to manufacture, and the cost is also high.

[0006] On the other hand, in the case of panels using calcium silicate plates, the structure was created using the papermaking method. A thin calcium silicate plate with a thickness of about 5 mm is attached to a metal frame placed on the back side. It is a fixed type, and like other panels, the structure is complex and the number of manufacturing steps is large. I needed it so much.

[0007]

[Means to solve the problem]

The invention of the present application was made to solve such problems, and the gist of the invention is as follows: has a strip-like shape, and has a plurality of internal through-holes in the longitudinal direction formed at a predetermined pitch in the width direction. A cement-based extruded board with a hollow structure is used as a wall material, and the chamber of the cement-based extruded board is After waterproofing and decorating the inner surface, the extruded cement plates are bonded together. It is characterized in that the side walls are formed by directly connecting each other (claim 1).

[0008] Another invention of the present application is to provide not only the indoor surface of the cement extruded board but also the back surface. It is characterized by being subjected to waterproof treatment (claim 2).

[0009] Still another invention of the present application is characterized in that the ceiling wall is constructed of the cement-based extruded board. (Claim 3)

0010 [Effects of actions and ideas] In this way, the present invention uses a single cement-based extruded board for the side walls of sanitary rooms such as bathroom units. They are configured by directly connecting them. Cement-based extruded board is a common building material, and is commonly used as a sizing material. It is used as an exterior wall material for buildings. However, conventionally, this cement-based extruded board has not been used as a wall material for bathroom units. not being used.

[0011] One of the main reasons for this is that cement-based extruded boards are used as wall materials for bathroom units, etc. If there is a 00 to 2200 mm) (small cement board to the bathroom unit). When used as wall materials such as walls, the number of connections between cement-based extruded boards becomes extremely large, making it difficult to implement. However, when such a large cement board is extruded, It is easy to cause large warping deformation, which makes it difficult to connect panels together and makes it difficult to connect them together. This is because the weight of each panel increases, making assembly work difficult.

0012 Cement-based extruded plates have such problems, so calcium silicate plates are used. In the case of a thin panel, it is made thin using the papermaking method (in the case of the papermaking method, it is naturally Reinforced by fixing a metal frame on the back side (prevents warping caused by extrusion) At the same time, a thin calcium silicate plate was restrained by the metal frame. I try to use it.

[0013] However, the calcium silicate plate obtained by the paper-making method as described above is thin. Therefore, when used as a wall material for bathroom units, etc., it has poor rigidity, heat retention, and insulation properties. In this respect, it is not necessarily satisfactory.

[0014] In contrast, in the present invention, the cement-based board has multiple internal through-holes in the longitudinal direction. It is extrusion molded with an internal hollow structure with a predetermined pitch in the direction, making it suitable for large cells. This avoids the warping problem peculiar to extrusion molded plates.

[0015] A cement extruded board with this structure consists of a pair of thin cement plates forming opposing front and back surfaces. The main body of the board is connected by many connecting parts (the parts of the body between the internal through-holes). This structure prevents the front and back forming parts from warping and deforming. This is because these connecting portions have a restraining structure.

[0016] In addition, this hollow structure significantly reduces the weight of the cement board. In addition to being easy to handle when assembling the unit, the presence of the hollow section also provides high maintenance. Demonstrates heat and insulation properties, and can effectively improve the functionality of bathroom units, etc. can.

[0017] In addition, this cement-based extruded board is inevitably thick (thickness above a certain level). (If not, it would be difficult to extrude), but combined with the material strength and hardness of cement, conventional A side wall with a solid feel and high rigidity and strength that could not be obtained with other units can be obtained. It will be done.

[0018] Moreover, according to the present invention, single extruded cement-based plates are connected, that is, a frame is attached to the back side. It is possible to construct a wall by directly connecting cement-based boards without any installation. Wear. In this case, the structure of the panel as a wall component unit is simple and the manufacturing process is simple. (just need to be extruded), which reduces the production cost of the panel and therefore the bathroom unit. The construction cost will also be low.

[0019] In addition to this, the present invention also uses the hollow part of the extruded cement plate to It has the advantage of being able to connect the boards together. The longitudinal through hole can be used as an engagement hole. This is possible, and by engaging the connecting fittings with this through hole, it can be connected to the cement board. This allows cement-based boards to be connected directly.

[0020] The invention of claim 2 waterproofs not only the indoor surface of the cement-based extruded board but also the back surface. This process provides the following benefits:

[0021] When using cement-based extruded boards as wall materials such as bathroom units, waterproofing on the surface side is required. Although the principle is essential, the reverse side is not necessarily necessary. However, the side walls of bathroom units, etc. may absorb water from the back side as well. In this case, the cement wall may warp due to water absorption from the back side. The cement body swells due to water absorption, but if this swelling occurs on the back side, this This causes warping. However, in the present invention, both the front and back of the cement-based board are waterproofed, so this This prevents warping caused by water absorption.

[0022] According to the invention of claim 3, the ceiling wall is constituted by the cement-based extruded board as described above. It is something. Traditionally, most ceiling walls in bathroom units, etc. are made of gypsum board. However, if this is constructed from a cement-based extruded board, it will improve the heat retention and insulation properties of bathroom units, etc. The effect of further increasing this can be obtained.

You can.

[0029] As the coating film 24 on the upper side of the decorative layer 22, those having the composition shown in Table 2 are used here. It is being The compositions in this table are also those at the preparation stage before curing.

[0030]

[Table 2]

[0031] These colored inorganic paint film 20, decorative layer 22, and translucent coating film 24 are, for example, as follows. It can be formed in this way. That is, first, a colored inorganic paint is applied to the surface of the cement substrate. Apply. In this case, the substrate is made of pulp other than asbestos, organic material such as polypropylene, etc. If the fibers are included as reinforcing fibers, the reinforcing fibers on the surface of the board may be exposed to water. This causes the reinforcing fibers to stand up and become fluffy. When the reinforcing fibers become fluffy, the tips of the fibers protrude onto the surface of the colored inorganic paint film 20. This may cause the product to come out and deteriorate its appearance. Therefore, in such cases, colored inorganic paints are used. Apply the paint in two parts, then apply the first coat of paint and let it dry to some extent. At this stage, the surface is polished with non-woven cloth to cut and remove the tips of the bristles, and then the second coat is applied. It is advisable to apply a liquid coating.

[0032] Now, after applying the colored inorganic paint, it is then cured. curing method and Then, this may be heated to a high temperature of about 300°C and cured by the action of heat. Then, once heated to about 120℃ to semi-cure, it is treated with a chemical solution and completely cured. It may be possible to do so. Here, ammonium phosphate aqueous solution is used as the chemical solution. be able to. Regarding curing using a chemical solution such as this ammonium phosphate aqueous solution, Since it is disclosed in detail in Japanese Patent Publication No. 62-39027, a more detailed explanation will be provided here. is omitted.

[0033] After the colored inorganic paint is cured in this way, the decorative layer 22 is then formed on it. Then, a translucent inorganic paint is applied thereon and cured. Tooru The photosensitive inorganic paint can be cured in the same manner as described above.

[0034] According to this example, a desired pattern or pattern and gloss are imparted to the cement-based extruded board 14. You can make it look beautiful.

[0035] The above description is merely an example of the decoration method, and the decoration method and It is possible to employ various other methods.

[0036] For example, titanium paper that has been screen printed in advance is impregnated with DAP resin on the substrate surface. Then, heat is applied to this to allow the DAP resin to penetrate into the cement substrate. It is also possible to solidify the cement substrate and then decorate the surface of the cement substrate.
