The present invention relates to a heat insulating wall panel, and to a method for manufacturing a ventilating/insulating wall panel that enables the ventilating/insulating wall panel to be efficiently manufactured with uniform quality.

(Prior Art and Problems to be Solved by the Invention) In recent years, in order to improve the insulation properties of walls and ensure the ventilation of the walls to improve the livability of buildings, insulation parts and ventilation parts have been installed. The walls of buildings are now being constructed using woven wall panels. Such a wall panel is formed by forming a heat insulating part inside a panel frame formed by framing frame materials, and also forming a ventilation part on the outdoor side surface of the panel frame. One of the points to pay special attention to when manufacturing panels is how to make the wall panels have good insulation properties, and how to efficiently make wall panels with uniform insulation performance. The question is whether to mass produce it. For this purpose, it is necessary to fill the inside of the panel frame with a heat insulating material without any gaps to improve the airtightness of the wall panel, and it is also necessary to perform the filling operation efficiently.

By the way, conventionally, glass wool and synthetic resin foam have been used as such heat insulating materials, but these heat insulating materials are often used in panel frames, especially in cases where braces are incorporated inside the panel frame. There was a problem in that it was difficult to fill the inside of the body without any gaps, and it was difficult to efficiently fill the insulation material.

The present invention primarily aims to provide a ventilation/insulation wall panel that can solve the above problems, and also to provide a method for manufacturing the ventilation/insulation wall panel. (Means for Solving the Problems) In order to solve the above problems, the present invention employs the following means.

The inner covering material 6 is formed of a net-like body (including a perforated sheet) provided with a large number of through holes 13 that prevent the passage of the foamed beads 12 and allow the passage of air. On the other hand, the outer covering material 7 is made of a material that exhibits windproof and waterproof properties, and the outer surface of the outer covering material 7 includes:

Further, in the method of manufacturing a ventilation/insulation wall panel according to the present invention, the indoor side surface of the panel frame 5 formed by framing vertical frame members 2 and horizontal frame members 3 in a rectangular shape is covered with an inner covering material 6, and The outdoor side surface is covered with an outer covering material 7, and the space 9 formed between the inner and outer covering materials is densely filled with a foamed bead aggregate board 10 made of synthetic resin, and the inner covering material 6 is The outer covering material 7 has windproof and waterproof properties, while being formed of a string-like body (including a perforated sheet) provided with a large number of through holes 13 that prevent the passage of the foamed beads 12 and allow the passage of air. The outer covering material 7 is made of a material that exhibits a When manufacturing a ventilation/insulation wall panel provided with a ventilation protrusion 22 that forms a communicating ventilation path 21: The indoor side surface of the panel frame 5 is covered with the inner covering material 6, and the outdoor side surface of the panel frame 5 is covered with the inner covering material 6. A foam bead 12 made of synthetic resin is formed by covering the side surface with an outer covering material 7 and applying a liquid adhesive to a space 9 formed between the inner and outer covering materials from the upper end of the space 9. After filling the void 9 with the foamed beads 12 while sequentially exhausting them through the through holes 13 of the inner covering material 6, the liquid adhesive is dried and the filled foamed beads are bonded together. This is characterized in that the foamed bead assembly plate 10 is formed by

(Function) The ventilation/insulation wall panel l having such a configuration has an outer wall material 20 attached to the outer surface of the ventilation protrusion 22 and an interior material 30 attached to the inner surface of the inner covering material 6. By this, the wall W of the building is formed. In the wall, the foam bead assembly plate 10 ensures good heat insulation of the wall. In addition, the air flows upwardly or laterally in the ventilation path 21 formed through the ventilation protrusion 22, thereby achieving effective ventilation inside the wall. Furthermore, since the outer covering material 7 is made of a material that exhibits windproof and waterproof properties, it reliably blocks cold air and rainwater from outside. (Example) Examples of the present invention will be described below based on the drawings. 1st~
FIG. 3 shows a ventilation/insulation wall panel 1 according to the present invention, and the ventilation/insulation wall panel 1 is made up of vertical frames 2, 2.2 and horizontal frames 3.3 separated by a required interval. The indoor side surface of the panel frame 5 constructed in a rectangular shape is covered with an inner covering material 6, and the outdoor side surface thereof is covered with an outer covering material 7, and a space 9 formed between the inner and outer covering materials is filled with synthetic resin. It is made by filling a foamed bead aggregate plate 10 of. In this embodiment, a brace 11 whose outer surface is flush with the outdoor side surface of the panel frame 5 is incorporated inside the panel frame 5. The inner covering material 6 is formed of a net-like material, such as inexpensive cheesecloth, provided with a large number of through holes 13 that prevent the passage of the foamed beads 12 and allow the passage of air, and the four circumferential edges l5 are fixed to the inner surface 16 of each frame member of the panel frame body 5 by adhesive or other means.

The outer covering material 7 is formed of a material that exhibits windproof and waterproof properties, such as a windproof/waterproof sheet made of a polyester nonwoven fabric that has been subjected to the necessary waterproofing treatment, and its four circumferential edges 17 are formed of a material that exhibits windproof and waterproof properties. It is fixed to the outer surface 19 of each frame member 5 by means of adhesive or the like.

The foamed bead assembly plate 10 filled in the cavity 9 formed between the inner and outer covering materials 6 and 7 collects a large number of foamed beads 12 made of synthetic resin (for example, foamed polystyrene beads) between the foamed beads. It is integrated into a plate shape by gluing. In addition, as shown in FIGS. 2 and 3, the outer surface of the outer covering material 7 is provided with:
A ventilating protrusion 22 is provided between the outer wall material 20 attached to the outer surface of the panel frame 5 and the outer covering material 7 to form a ventilating passage 21 communicating with the outside at the top, bottom, right and left. In this embodiment, the ventilation protrusion 22 is formed of vertical crosspieces 23, 23.23 attached to the outer surface of the outer cover 7 so as to overlap the outer surface of each vertical frame member 2, 2.2. and horizontal crosspieces 25 attached at required intervals in the vertical direction while connecting the vertical crosspieces 23, 23.23, and the outer surface of the vertical crosspieces. 26 and the outer surface 27 of the horizontal crosspiece are formed flush with each other. Furthermore, a ventilation gap g is formed between the horizontal crosspiece 25 and the outer covering material 7, as shown in FIG. 3, and a ventilation notch 29 is formed in each vertical crosspiece 23. ing.

The ventilation/insulation wall panel l having such a configuration is used to form the wall of a building, and as shown in FIG.
The building wall W can be formed by attaching the outer wall material 20 to the outer surface 27) of the inner covering material 6 and the outer surface 27) of the inner covering material 6, and adding the interior material 30 to the inner surface of the inner covering material 6. In the wall constructed in this way, the foamed bead assembly plate 10 can provide good insulation for the wall, and the ventilation passages 21 formed through the ventilation protrusions 22 can be directed upwardly or laterally. The airflow allows effective ventilation inside the wall.

The arrows in FIG. 2 indicate the state of air flow in the ventilation path 21 formed by adding external wall material (not shown). In this embodiment, the outer surface 26 of the vertical crosspiece
Since the outer surface 27 of the crosspiece and the outer surface 27 of the horizontal crosspiece are formed flush with each other, the outer wall material 20 can be attached freely in the vertical or horizontal direction on the outer surface of the ventilation protrusion 22. ．． In addition, since the outer sheathing material 7 is made of a material that exhibits windproof and waterproof properties, even if cold air or rainwater enters from the joints of the exterior wall materials, the outer sheathing material 7 can reliably block them. ．． Note that in this embodiment, since a sheet is used as the outer covering material 7, when the ventilation/insulation wall panel is to be constructed with the struts 11, the struts 11 can be seen through the sheet. The presence or absence of differences can be inspected at the construction site.

FIG. 4 shows another type B of the outer covering material 7, in which the whole is integrally formed of synthetic resin foam, and the ventilation protrusions 22 as independent bodies are formed protruding from the surface at required intervals. It has been done. Note that the ventilation/insulation wall panel according to the present invention may be configured to include various openings such as window openings and ventilation fan openings.

The ventilation/insulation wall panel 1 having such a configuration is manufactured, for example, by the following manufacturing method. That is, first, a panel frame 5 is formed by framing vertical frame members 2 and horizontal frame members 3 into a rectangular shape.
At the same time, a brace 1l is installed inside the panel frame 5' as necessary, and the indoor side of the panel frame 5 is
Through hole 1 that blocks the passage of foam beads and allows the passage of air
3 is covered with an inner covering material (for example, cheesecloth) made of a net-like material 6, and an outer covering material (windproof/waterproof material) made of a material that exhibits windproof and waterproof properties. sheet, etc.) 7, and the outer surface of the outer covering material 7 is provided with a ventilation protrusion 2 having the above-mentioned structure, for example.
2, a synthetic resin foam is applied to the space 9 formed between the inner covering material 6 and the outer covering material 7 from the upper end of the space 9. A large number of beads 12 are supplied pneumatically. At this time, the air sent into the cavity 9 through the through hole 13 of the inner covering material 6 is sequentially discharged from the through hole 13, and the foamed beads 12 are filled into the cavity 9. Since the inner covering material 6 is formed of a net-like body as described above, when filling the void 9 with foam beads, the filling state of the foam beads into the void 9 can be checked through the mesh. This can be done visually. Therefore, it is possible to densely fill the foamed beads without creating any unfilled areas at the intersections between the striations and the vertical frame members. Note that after filling is completed, the foam bead supply section 3 of the inner covering material 6
1 (see Figure 5). After the filling is completed, the liquid adhesive is dried through a drying process, whereby the filled foam beads are bonded and integrated with each other to form the foam bead assembly plate 10. (Effects of the Invention) The present invention has the following excellent effects. ■ The ventilation/insulation wall panel according to the present invention has the panel frame densely filled with foamed bead aggregate plates, so each part of the panel has uniform heat insulation properties.In addition, since the outer surface of the foam bead assembly board is covered with an outer covering material made of a material that exhibits windproof and waterproof properties, the outer covering material prevents cold air from outdoors. Due to the synergy of these effects, the wall constructed using the ventilation/insulation wall panel according to the present invention can have extremely excellent heat insulation properties.

■ Ventilation/Insulation Since the external wall material is attached to the outer surface of the ventilation protrusion of the outer covering material of the wall panel to form a ventilation path, ventilation and insulation are achieved by the air flow in the ventilation path. The interior of a wall constructed using wall panels can be effectively ventilated. In addition, since the outer surface of the foam bead assembly board is covered with an outer covering material made of a material that exhibits waterproof properties, even if rainwater enters from the connection parts of the external wall material, it can be reliably blocked. ．． ■ The manufacturing method according to the present invention involves forming an inner covering material that covers the indoor side surface of a panel frame using a net-like material, and using air pressure to inject a large number of synthetic resin foam beads to which a liquid adhesive is attached into a space. Since the air in the cavity is supplied through the holes, it is possible to efficiently fill the foam beads while sequentially discharging the air from the holes. Also, at that time, the filling process can be performed while visually checking the filling state through the through-holes of the net-like body, so that there are no unfilled areas, even when braces are built into the panel frame. , it is possible to densely fill the entire cavity with foam beads. Then, by drying the liquid adhesive through a drying process after filling is completed, it is possible to form a foam bead assembly plate in which the filled foam beads are adhered to each other. In this way, when using the manufacturing method according to the present invention,
The foam beads can be densely packed into the panel frame efficiently, and it is possible to manufacture ventilation/insulation wall panels of uniform quality.
