2. Description of the Related Art A building unit such as a house is composed of four columns at four corners, a ceiling beam connecting the upper and lower ends of these columns, a floor beam, an outer wall material, an inner wall material, and a ceiling. It was constructed by attaching lumber, flooring, etc. When making a wall of a conventional house, a wooden crate for the inner wall foundation is formed on the site inside the outer wall, a heat insulating material is installed between them, and a gypsum board is attached to the inside of the wooden crate for the inner wall foundation. It was completed by pasting wallpaper. In addition, in the prefabricated construction method using wall panels that has been widely adopted in recent years, in order to reduce the on-site construction, the wall panel with built-in heat insulating material is manufactured at the factory, but the plasterboard and wallpaper are installed on-site. Met.

[0003]

However, according to the above-mentioned conventional construction method, three or four layers are required to construct the inner wall inside the outer wall.
There is a problem that it takes a lot of time and labor, and the construction period becomes extremely long. That is, first, a heat insulating material is attached and an inner wall foundation wooden frame that forms an inner wall is created. In addition, a gypsum board was attached to the surface of the wooden frame on the indoor side, and further wallpaper had to be attached to complete the process. Furthermore, since the wooden frame for the inner wall foundation is originally poor in dimensional accuracy, a skilled carpenter with special skills is required to mount the gypsum board or wallpaper on the top of the wooden frame without any steps, and therefore the construction period is long. , There was a problem of raising the cost of the entire house.

The wall panel according to the present invention is a completely new technology developed in view of the above-mentioned conventional problems, and is particularly easy to manufacture, can be mass-produced in factories, and is used at a construction site. The present invention provides a technology for a wall panel having a completely new structure that is excellent in workability, heat insulation, sound insulation, strength, and aesthetics.

[0005]

A wall panel according to the present invention is a technique which has been fundamentally improved from the above-mentioned conventional problems.
The gist of the first invention is a wall material used as an outer wall material for construction, an inner wall material, a partition material, or the like, and is configured by filling a heat insulating material inside a synthetic resin cylindrical outer box. It is a wall panel characterized by that.

The gist of the second invention of the present application is the wall panel of the first invention, characterized in that the heat insulating material is a foamed resin formed in the form of a molded sheet or beads. The gist of the third invention of the present application is a wall material used as an outer wall material for construction, an inner wall material, a partitioning material, or the like, in which a foamed resin, gypsum, concrete or the like is placed inside a synthetic resin tubular outer box. A wall panel characterized by being filled with a selected heat insulating material and a sound insulating reinforcing material.

The gist of the fourth invention of the present application is that the heat insulating material and the sound insulating reinforcing material are mixed homogeneously with each other, or are unevenly distributed, or separated from each other, and are filled in the synthetic resin cylindrical outer box. It is the wall panel of the 3rd invention characterized by being present.

A fifth invention of the present application is a wall material used as an outer wall material for construction, an inner wall material, a partition material, or the like,
A sound insulation reinforcement material made of gypsum or concrete filled in a synthetic resin cylindrical outer box is foamed with a foaming agent, and independent air bubbles are provided inside the sound insulation reinforcement material to form a heat insulation material. It is a wall panel that doubles as a feature.

The synthetic resin cylindrical outer box used in the present invention is made of a thermoplastic synthetic resin having a resin thickness of about 1 to 3 mm and having the following characteristics. That is, the specific gravity is as light as 0.9 to 1.5, and a large number of complicated shapes can be easily formed at low cost by an injection molding method or an extrusion molding method. Further, as a bending strength structure of an inner wall or partition wall of a house, for example, a longitudinal elastic modulus is about 300 kgf /
It has suitable bending rigidity of mm ² or more and mechanical properties such as impact resistance. Furthermore, the dimensional stability is good, the surface after molding is beautiful, and coloring during molding is free, and secondary processing such as surface coating and surface printing is easy. As such materials, hard vinyl chloride resin, polystyrene resin, acrylonitrile-butadiene-styrene resin (ABS resin), modified polyphenylene ether (modified PPE resin)
Or modified polyphenylene oxide (modified PPO resin)
Etc. are suitable. Further, a reinforced resin such as a reinforced polypropylene resin in which glass fibers or various fillers are added to these resins to increase the rigidity is also suitable. Further, a flame-retardant grade resin having a self-extinguishing property to which a phosphorus-based or halogen-based flame retardant is added is also suitable as a flame-retardant housing building material. In this respect, a hard vinyl chloride resin or a modified PPE resin is preferable. In addition,
The material of the resin box may be other thermoplastic resin or thermosetting resin as long as it can achieve the above purpose.

The heat-insulating foamed resin used in the present invention is preferably a highly foamed synthetic resin having a fine closed cell structure and a foaming bulk ratio of 40 to 80 times. For example, foamed polystyrene, foamed polyethylene, vinyl chloride foamed material, hard urethane foamed material and the like are suitable, and the density is 0.01 to 0.05 g / cm ³ . Further, it is more preferable that a flame retardant is added to the foam to make it flame-retardant. The shape of the heat-insulating foamed resin is a sphere (bead) shape, a molded sheet shape, or the like, but the heat-insulating foamed resin can be freely selected within a range such that it can be put into a resin box and a desired heat-insulating effect is obtained. However, in the case of spheres (beads), those having a diameter of 5 mm or less are desirable. In the case of expanded polystyrene produced by a steam expansion molding method, a so-called molding method, pre-expanded polystyrene beads that have undergone primary expansion (pre-expansion) at an expansion ratio of 60 to 80 are formed by secondary expansion. Instead, it can be used as it is. Further, a urethane resin or the like capable of foaming on site can be directly injected into a resin box to form a foam. In addition, even in heat insulating foamed resin,
Foams of other thermoplastic resins may be used as long as they can achieve the above objects.

The gypsum used in the present invention is kneaded with calcined gypsum obtained by firing natural gypsum or chemical gypsum and put into a resin box. The setting and hardening time can be adjusted by adding a setting retarder. The ratio of the heat-insulating foamed resin to the plaster and / or concrete to be put in the resin box is set in consideration of heat insulation, soundproofing performance and workability required for the wall panel.
For example, in the case of heat-insulating foamed resin and gypsum, the volume ratio of gypsum and / or concrete is preferably about 5 to 30% in terms of heat insulation, soundproofing performance, and ease of transportation due to weight reduction.

[0012]

The wall panel according to the first aspect of the present invention has an extremely simple structure and can be mass-produced at low cost because it is only necessary to fill the heat insulating material in the cylindrical outer case made of synthetic resin.
Further, since the outer surface of the wall panel is formed by the synthetic resin cylindrical outer box, the entire outer surface is smooth, glossy and beautiful. Therefore, the wall panel can be used as it is as an outer wall material / inner wall material, or as a partition material without secondary processing on the surface. The synthetic resin cylindrical outer box can be colored in a desired color at the time of production, and if necessary, surface coating, surface printing, wallpaper or the like can be attached to the surface for use. Synthetic resin cylindrical outer boxes can be mass-produced at low cost by effectively utilizing plastic waste materials. In the case of using the wall panel configured by using the synthetic resin tubular outer box of the present invention, the construction work of the conventional inner wall foundation frame, the heat insulating material, the gypsum board wallpaper, etc. as described above is completely omitted. It can be unnecessary.

Further, since the synthetic resin cylindrical outer box is formed by molding synthetic resin, the dimensional accuracy is extremely high, so that the accuracy of mounting on the building frame can be remarkably improved and the mounting work can be performed. It is simple and when a plurality of wall panels are arranged side by side, they can be in close contact with each other without forming a gap between them. Therefore, the construction can be facilitated, and the construction can be easily performed even if the carpenter does not have a special skill. Further, in the first invention of the present application, since the heat insulating material such as foamed resin is filled inside the synthetic resin cylindrical outer box, it is possible to form a wall panel having extremely high heat insulating properties. In the case of the present invention, the required strength can be imparted to the tubular outer box made of the constituent resin itself by adjusting the wall thickness and the reinforcing ribs, so that it can be used as a wall material as it is.

In the second invention of the present application, the heat insulating material such as foamed resin filled in the cylindrical outer casing made of synthetic resin is formed into a molded sheet shape or a bead shape. It can be filled in a synthetic resin cylindrical outer box. In addition, the bead-shaped heat insulating material can be filled in the synthetic resin tubular outer box at the building construction site in the synthetic resin tubular outer box for site construction.

In the third invention of the present application, the synthetic resin tubular outer box as described in the operation of the first invention is used, and the synthetic resin tubular outer box has a foamed resin, gypsum and concrete inside. Since the heat insulating material and the sound insulation reinforcing material selected from the above are filled, a wall panel having higher strength and sound insulation can be configured as compared with the wall panel of the first invention.

According to the fourth aspect of the present invention, the heat insulating material and the sound insulating reinforcing material are homogeneously mixed with each other, unevenly distributed, or separated from each other and filled in the synthetic resin cylindrical outer box.
It is possible to construct a wall material having excellent heat insulation, sound insulation, and strength with the entire wall panel. In particular, when the heat insulating material and the sound insulation reinforcing material are unevenly distributed or separated inside the synthetic resin cylindrical outer box, a wall panel having more excellent heat insulation and sound insulation can be configured.

In the fifth invention of the present application, the outer box is formed of a synthetic resin in a tubular shape, and the sound-insulating reinforcing material, such as gypsum or concrete, filled in the outer box is foamed with a foaming agent, Since it is configured with closed cells inside it, in addition to the sound insulation strength of the sound insulation reinforcement material,
Heat insulation can be provided by the closed cells provided inside the soundproofing reinforcing material. Therefore, in the fifth aspect of the invention, the heat insulating material made of the foamed resin as shown in the second aspect and the fourth aspect of the invention can be omitted to simplify the entire structure.

This is an example of being divided. On the other hand, this embodiment is an example in which the expanded polystyrene 3 and the gypsum 4 are unevenly distributed in the direction of the wall thickness 14 inside the hard vinyl chloride box 2 as shown in FIG. . In this case, the second embodiment
And has the following features as compared with the fifth embodiment. That is, in Example 2, it may be difficult to ensure the required heat insulation performance under the design conditions in which the ratio of the gypsum 4 to the input ratio of the expanded polystyrene 3 is large. Further, in Example 5, the layer of expanded polystyrene 3 and the layer of gypsum 4 are installed in series in the thickness direction of the wall, so that the heat insulating performance is superior to that of Example 2 even if the ratio of plaster is relatively large. It is necessary to separately manufacture the layer of expanded polystyrene 3 and the layer of gypsum 4, and a separator is also required. On the other hand, in this embodiment, the expanded polystyrene 3 and the gypsum 4 can be charged at the same time, and since they are unevenly distributed in the direction of the wall thickness 14, the layers of the expanded polystyrene 3 and the gypsum 4 are apparently formed.

Further, the recycled foamed resin can be used by crushing it into an appropriate size without any special regeneration treatment.
Further, by further complicating the shapes of the fitting concave groove 5 and the ridge 6 for connecting between the wall panels in FIG. 3, the tightness of the walls connected by the plurality of wall panels 1 is improved, The moistureproof effect of the wall panel 1 is improved. Example 2 described above
Then, in the production stage of the wall panel 1, after the expanded polystyrene 3 was put into the rigid vinyl chloride box 2, the plaster 4 kneaded with water was put, but the expanded polystyrene 3, the plaster 4 and water were kneaded in advance. Alternatively, this may be put into the hard vinyl chloride box 2 and solidified. Alternatively, the polystyrene foam 3, the gypsum 4, and water may be kneaded in advance, molded and solidified, and then inserted into the hard vinyl chloride box 2.
