2. Description of the Related Art From the viewpoint of environmental protection and resource protection on a global scale, environmental measures such as energy saving and recycling have been called for a long time, but there is still no decisive point.
It is well known that this is an important theme for society and industry in the future. Among the environmental measures, as a technology to recycle various industrial waste generated in various industries and household waste generated in ordinary households as a raw material for building material tiles that can be expected to consume a large amount, for example, Proposals have been made such as Japanese Patent Publication No. Hei 7-88248 “Ceramic sintered body”. This proposal is useful in terms of recycling of garbage, and the obtained sintered body also has excellent characteristics. However, when its content is examined in detail, there are the following problems.

That is, since a material is obtained by firing and sintering, not only energy consumption in the manufacturing process is large, but also global warming is promoted as a result. Also, due to manufacturing reasons, the resulting product is a rectangular block-shaped or flat tile, so when used as a building interior / exterior building material, an adhesive such as mortar is usually required, and metal-based exterior Poor workability compared to materials and ceramic building materials that can be nailed.

And a fixing portion protruding toward the interior and exterior base. The main raw materials of the interior and exterior parts are recycled raw materials obtained by treating waste, for example, industrial waste such as paper pulp sludge and slag incinerated ash,
Or, general household waste such as paper, various plastics, rubber, glass, bottles and the like may be crushed or made into a raw material state by other known means. In the present invention,
The main raw material of the interior and exterior parts is not limited to the above-mentioned recycled raw material, but also includes the use of an unused material having the same, the same quality, and the same composition. Thus, the composite interior / exterior building material of the present invention is obtained by curing the material obtained by kneading the main raw material and the binder on the surface of the core material, forming the interior / exterior portion in contact with the surface of the core material, In addition to supporting the inner and outer portions, the embedded portion is embedded in the middle of the inner and outer portions in the thickness direction to integrate the inner and outer portions, the core material, and the metal base material.

In such a configuration, the interior and exterior portions are formed without using any means such as firing or sintering, and the interior and exterior portions and the core material are integrally formed without using fixing means such as bonding or screwing. Can be Further, since the buried portion has a large number of through holes, it is firmly bonded to the cured product, and the interior and exterior portions, the core material, and the metal base material are firmly integrated. The composite interior / exterior building material of the present invention is configured such that the fixing portion of the metal base projecting to the interior / exterior base side is attached to the interior / exterior base using various fixing means such as nailing, bolting, and concave / convex engagement. Become.

Examples of the core material include known heat insulating materials and fire-resistant materials such as polyurethane foam, polystyrene foam, polyethylene foam, isocyanurate foam, glass wool and wood wool cement board.

As the main raw material, there are several kinds described above, and it is preferable to use glass cullet in consideration of design properties and the like. Examples of the main composition of the binder kneaded with the main raw material include polymer cement mortar and cement containing an emulsion.

[0010] Glass cullet is used as a main material and polymer cement mortar is used as a binder, or pulp sludge is used as a main material and cement is used as a binder. Can be cited as an example of a preferred embodiment.

When the glass cullet and the polymer cement mortar are kneaded and cured, more specifically, a polymer cement mortar containing a water-soluble synthetic resin emulsion may be used. For example, as a reinforced aggregate in hydraulic cement, using fine powder of natural silicate minerals, fine glass powder, and mixing with a water-soluble synthetic resin emulsion to form a reinforced cement board that becomes a solidified high-strength polymer cement Can be.

Also, a bittern component as a curing agent can be added. At least one of a fungicide and a deodorant may be mixed. In addition, as the pulp sludge, pulp sludge at the time of recycling used paper can be used in addition to the papermaking pulp sludge.

When the inner and outer portions are formed within the formation range of the through hole in the buried portion, the bonding and integration between the inner and outer portions and the metal base material become stronger, and cracks in the inner and outer portions due to aging are reduced.

The concave portion can be formed partially or continuously at a predetermined position on the surface of the core material. When the concave portion is continuously formed in the vertical direction, the horizontal direction, the oblique direction, etc. on the surface of the core material, it becomes a concave groove shape. . It is also possible to provide a recess at the peripheral edge of the surface of the core material. In this case, a rib-like reinforcing portion is formed at a corner portion of the wraparound portion, thereby improving the durability of the wraparound portion and restricting the expansion of the fixing portion.

In addition, a thick reinforcing portion is formed at a corner on the back surface of the interior / exterior portion facing the tapered portion, and further a concave portion is provided in the tapered portion, and the concave portion is fitted to the thick reinforcing portion. It is also possible to adopt a configuration in which a rib-shaped reinforcing portion is formed. In this case, in addition to the reinforcement of the corner portion of the wraparound portion by the thick-walled reinforcement portion, the rib-like reinforcement portion and the concave portion of the tapered portion bite into each other due to unevenness. This is more reliably performed and greatly contributes to preventing the fixed portion from expanding.

Is preferred because the embedded portion is set to the finished dimensional level, and the position of the embedded portion is stable, which is useful for ensuring accuracy and strength, and can improve workability during manufacturing. In addition, since a large number of projections are provided on the core material surface, the joint area between the interior and exterior parts and the core material is enlarged, and the joint part between the interior and exterior parts and the core material digs into each other due to unevenness, The bonding and integration of the two becomes stronger.

The fixing portion is formed separately from the embedding portion, and a locking portion is provided at an upper end portion of the fixing portion to be fitted to a convex portion formed on the side surface of the core member. In this case, the metal base material is set by mounting the fixing portion on the core material and then placing the embedded portion on the surface of the core material, thereby facilitating the production. In addition, as a result of the structure in which the left and right fixing parts are integrally joined to the core material, the three members of the interior / exterior part, the core material, and the metal base material are more firmly integrated.

In the case where a structure is provided which includes a restricting means for restricting the expansion of the fixing portion, it is possible to effectively prevent the inner and outer portions from being cracked due to the expansion of the fixing portion. As described above, as the mode of the restricting means, as described above, a means for forming a tapered portion on the peripheral edge of the surface of the core material and forming a thick reinforcing portion on the back surface of the inner / exterior portion facing the tapered portion, the surface of the core material Means for providing a concave portion at a predetermined location and forming a rib-like reinforcing portion at a portion of the inner / exterior portion opposed to the concave portion, or extending a lower edge portion of the core material laterally and engaging with an outer edge of the fixing portion. Means for forming an extended portion to be joined, means for providing a backing made of kraft paper, various films, metal thin plates, etc. between the right and left fixed portions, and forming a core material by a resin foaming technique in a known sandwich panel or the like. Means for integrally forming the material and the base material in advance, means for performing partial taping and fixing the fixing portion to the core material with tape, and the like can be exemplified, and these means can be appropriately combined.

As a preferred method of manufacturing the composite interior / exterior building material according to the present invention, a core material and a metal base material are set on a base of a molding die, and a side mold is arranged around a surface side of the core material. After forming a molding space, a binder is mixed with recycled materials obtained by treating waste or materials of the same quality.
There is a method of filling a kneaded interior / exterior material into the molding space, curing and releasing the mold to obtain a composite interior / exterior building material. The set of the core material and the metal base material is, for example, a means for mounting the core material on the base of the molding die and assembling the metal base material with the core material, a core material integrally formed by assembling the metal base material in advance. Means for mounting on a base can be exemplified. Given the productivity gains,
It is preferable that the core material and the metal base material are formed integrally in advance. In order to improve the filling efficiency and molding efficiency of the interior / exterior material, it is preferable to pressurize the interior / exterior material surface during and after filling the interior / exterior material into the molding space. Examples of the method include a simple planar press from above and a traveling press using a pressure roll. When the interior and exterior parts are pulp sludge cement, the pressurization is useful, and when the interior and exterior parts are glass cullet and polymer cement mortar, effects such as applying a pattern to the surface by the pressure can be further expected. .

The joint space formed between the interior / exterior portions 1, 1 of the adjacent composite interior / exterior building materials A, A may be filled with a packing and a filler as necessary to form the joint.

The interior / exterior part of the composite interior / exterior building material according to the present invention can be appropriately subjected to conventionally known surface makeup and waterproof / fireproof treatment according to the necessity. For example,
When the interior and exterior part 1 is mainly made of paper pulp sludge,
Since the water absorption is relatively high, at least the surface 1c and the side 1
It is desirable to apply a waterproof paint or the like to a. When the interior / exterior portion 1 is mainly composed of a main raw material of a low water-absorbing material and a cement-based binder, a marble pattern or any other design can be provided on the surface 1c by silk screen technology. If glass cullet is used as the main material and colored cement is used as the binder cement, a high design property can be obtained as it is.

When manufacturing a composite interior / exterior building material in which the embedded portion 3a of the metal base material 3 is embedded in the middle of the interior / exterior portion 1 in the thickness direction, the metal base material 3 is placed in a predetermined mold.
Is set, and then the molding material (inner / outer part material) of the inner / outer part 1 is charged, and after curing, the mold is released to obtain a composite inner / outer part building material. However, in such a method, there is a possibility that sagging may occur due to the weight of the embedded portion 3a at the stage of setting the metal substrate 3, and the tendency becomes more remarkable as the face plate portion of the interior / exterior portion 1 becomes larger. It is difficult to stably secure the position accuracy of the portion 3a. When a slurry, mortar, cream, or other semi-solid interior / exterior material, which is a molding material for the interior / exterior portion 1, is charged into such a metal base material 3, the positional accuracy of the embedded portion 3a is reduced. There is a possibility that the material may be cured while being unstable. On the other hand, when the manufacturing method according to the present invention is adopted, the above-mentioned problem can be solved.

An embodiment of the method for manufacturing a composite interior / exterior building material according to the present invention will be described below with reference to FIG. 16 using the composite interior / exterior building material A shown in FIGS. 1 to 3 as an example. In the figure, D is the base of the mold, E is the side mold, and F is the recycled material obtained by treating waste or a material of the same quality as the interior and exterior part material consisting of a kneaded material of the main material and binder. As an example of the material F, a white cement, a fine powder of natural silicate ore (ironite), a fine glass powder, and a water-soluble synthetic resin emulsion mixed in the above-described mixing ratio to form a creamy mixture. Using.

After the core 2 and the metal base 3 are set on the base D of the molding die, the side mold E is used to form a molding space G for the interior / exterior portion 1 around the surface of the core 2. It surrounds the periphery of the core material 2 and the metal base material 3 except for the molding space G.

Then, the core member 2 is first placed on the base D, and the fixing portions 3b, 3
Set c (see Figure A). Next, an embedded portion 3a is set on the core material 2 from above, and the embedded portion 3a is supported by a large number of convex portions 5 so as to be positioned at an intermediate position in the molding thickness of the interior / exterior portion 1. In order to form a molding space G of the interior / exterior portion 1 around the side, a side mold E is arranged to surround the periphery of the core material 2 and the metal base material 3 (see FIG. 1A).
The core member 2 integrally formed by previously assembling the fixing portions 3b, 3c and the embedded portion 3a is placed on a base D, and then the molding space G of the inner / exterior portion 1 is formed around the surface side of the core material 2. To form the core material 2 and the metal substrate 3
Can also be surrounded. In this case, the core material 2
Since the metal substrate 3 and the metal substrate 3 are formed in advance integrally, an improvement in productivity can be expected.

Thereafter, the interior and exterior part material F is charged into the molding space G up to the molding level of the interior and exterior part 1 and filled. When the surface of the interior / exterior part material F is pressurized with the upper mold H during and after the filling, it is possible to improve the filling efficiency and the molding efficiency of the interior / exterior part material F (see FIGS. U to D). . Then, after curing for a predetermined time, demolding after curing, and further curing, post-treatment such as surface treatment is performed as necessary to obtain a composite interior / exterior building material A. The obtained composite interior / exterior building material A has an embedded portion 3 a having a large number of through holes 4 and a large number of convex portions 5.
And the core material 2 having a strong bond with the cured product, and the interior / exterior part 1, the core material 2, and the metal base material 3 are firmly integrated. In addition, the embedded portion 3a is supported by the convex portion 5 of the core member 2, and the core member 2 serves as a receiver for the interior / exterior material F. The core member 2 is effective in preventing the embedded portion 3a from bending and preventing sagging due to its own weight. There is almost no sinking of the buried portion 3a when F is supplied, and the positional accuracy of the buried portion 3a can be stably secured. Further, the molding die G is formed by arranging the side mold E around the surface side of the set core material 2 and the metal base material 3, and the molding material is put into the space G, and after the curing, the side die E is removed. Since the interior / exterior portion 1 is formed and the interior / exterior portion 1, the core material 2, and the metal base 3 are firmly integrated, for example, a molding space is recessed in the base D and the metal base 3 is set at a predetermined level. As compared with a method in which a molding material is charged in stages and cured, and the interior / exterior part 1 is taken out from the molding space after curing, the limit of the production size can be eliminated and a significant improvement in productivity can be expected.

In the manufacturing method of the present embodiment, the base D of the molding die is not limited to the shape shown in the figure, but may be any of various shapes such as, for example, those having a substantially concave cross-sectional shape having a peripheral wall portion rising outside the side die E. Changes are possible. Further, it goes without saying that the manufacturing method of the present example can also correspond to an embodiment in which a part of the composite interior / exterior building material A shown in FIGS. 1 to 3 is changed as shown in FIGS. In this case, it goes without saying that the shape, dimensions, and the like of the base D and the side mold E are appropriately changed in accordance with changes in the shapes of the interior / exterior portion 1, the core material 2, and the metal substrate 3.
