Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a method for manufacturing a heat insulating panel provided with a wiring space for wiring equipment used in, for example, industrially manufactured houses.

[0002]

[Prior art]

 When using a double-sided heat-insulating panel with a heat-insulating material layer in the middle on both sides on the outside and using a double-sided heat-insulating panel on the indoor side wall, most of the heat-insulating material is glass wool, rock wool or other fibrous materials. . If it is necessary to wire electric wires inside this heat insulating panel, a cardboard paper tube is buried in the panel assuming the wiring position in advance, and the electric wires are drawn into this paper tube.

[0003] Further, in a known conventional example described in Japanese Utility Model Application Laid-Open No. 53-70715, a foamed board provided with a plurality of wiring pipe passages in advance in the vertical and horizontal directions is prepared, and both sides of the board are formed. A panel with a surface material is used. According to such a conventionally known means, at the time of wiring, a path at a required wiring position is selected from the above-mentioned multiple pipe paths, and wiring is performed in the path.

[0003]

[Problems to be solved by the invention]

 According to the above-mentioned conventional heat insulating panel, the operation of drawing the electric wire into the paper tube is extremely complicated. This is because the pre-buried paper tube is easily misaligned by a slight external force because the insulating material is made of irregular fibrous material, making it difficult to determine the position and passing the electric wire through the paper tube. It is difficult. Filling the insulation with a hard material to suppress the displacement of the paper tube creates a risk of lowering the heat insulation, increasing the weight and increasing the cost. Furthermore, when an opening is made in the plate material on the panel surface for mounting a switch box or outlet, a large amount of heat insulating material tends to protrude from the inside, which increases the time and effort for removal processing.

[0004] Further, in the case of using a ready-made foam board, a board in which a large number of wiring paths are provided in advance on the foam board is separately prepared, so that the manufacturing process of a heat insulating panel as a house building element becomes extremely complicated. Not only that, thermal insulation panels using only foam boards must be expensive. Furthermore, it is conceivable to use inexpensive glass wool, etc., but the work of integrating the above-mentioned board with wiring passages with the glass wool heat insulating material layer, and storing and fixing it to the panel frame and outer wall material is complicated. Its construction is extremely difficult. The present invention solves the above-mentioned disadvantages, and provides a new method of manufacturing a heat insulating panel provided with a wiring space for wiring equipment, in which wiring equipment can be easily arranged inside the panel.

[0005]

[Means for Solving the Problems]

 In the present invention, a plate material is adhered to one side of a frame and a reinforcing core, a fibrous heat-insulating material layer is formed in a recess formed by the frame and the plate, and a wiring passage is formed on an inner surface of the plate for the other side. The pipe is fixed, and the plate for the other side is attached to the other side of the frame, and then a foaming resin is filled in a space formed by the frame, the fibrous heat-insulating layer, and the inner surface of the plate for the other side. This is a method for manufacturing a heat insulating panel for fixing the fibrous heat insulating material layer and the wiring passage tube by filling and foaming.

Embodiment

 Therefore, an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a heat insulating panel 1 manufactured by the method of the present invention has a frame 2 at the periphery and a reinforcing core 3 disposed in the plane, and plates 4a and 4b adhered to both sides. It is one in which a multi-layer type heat insulating material layer 5 is filled in a hollow panel of a mold. The multilayer heat-insulating material layer 5 was formed by laminating a fibrous heat-insulating material layer 6 and a foamed plastic heat-insulating material layer 7.

The heat insulation of the fibrous heat insulating material layer 6 is generally inferior to that of the foamed plastic heat insulating material layer 7, but is inexpensive. In the example, a mat-like molded body of glass wool heat insulating material having a thickness of 70.5 mm was used. The other foamed plastic heat-insulating material layer 7 generally has a lower thermal conductivity than the above-mentioned fibrous material and has excellent heat insulating properties, but is expensive. In the examples, urethane foam was used. Specifically, a plate material 4a is attached to one surface of the heat insulating panel 1, the plate material 4a is placed horizontally with the plate material 4a facing down, and a glass wool heat insulating material is laid, and then the plate material 4b is attached. Next, urethane insulating material was injected into the space between the plate member 4b and the glass wool insulating material layer, foamed to a thickness of about 40 mm, and filled without gaps.

A plywood having a thickness of 5.5 mm is used for the plate member 4 a of the heat insulating panel 1, and a plywood having a thickness of 4 mm is used for the plate member 4 b. The total thickness was 120 mm.

Then, as shown in FIG. 2, a space 9 for disposing wiring equipment 8 such as electric wires, wiring equipment and switches is provided in the foamed plastic heat insulating material layer 7 below the plate 4b. Therefore, the placement space 9 is formed by determining the position and shape of each placement space 9 of each wiring equipment 8 from the details of the wiring plan relating to the heat insulating panel 1. For example, as shown in FIG. 2, a paper tube 11 through which an electric wire 10 passes, a lower outlet 12, a switch 13 at an intermediate height, an upper end of the electric wire 10 in the paper tube 11 above, and an electric wire of a ceiling wiring not shown in the drawing. Each arrangement space 9 is formed in accordance with the position and shape of the opening 14 and the like for connection with the device.

In the present embodiment, the paper tube 11 is attached to a predetermined position on the back surface of the plate member 4b and then attached to the frame 2, and then urethane insulating material is injected and foamed. In the case of a long and thin paper tube 11, the above method is the most accurate and easy to place the paper tube 11, which is the space 9 for disposing the electric wire 10. The outlets 12, the switches 13, the openings 14 and the like, which are the wiring equipment 8 other than the paper tube 11, are provided with openings at the respective positions of the plate 4b at the construction site where the heat insulating panel 1 is to be disposed, and the openings are formed from the openings. The urethane foam layer was cut into a required shape to form each disposing space 9.

Since these are not elongated like the above-mentioned paper tube, they are easy to cut by the foamed plastic heat insulating layer even in the so-called post-processing as described above, and the heat insulating material does not protrude from the surroundings and is easily formed. Can be implemented. The space 9 for disposing the wiring equipment 8 may be formed by burying, for example, a box having the same shape at the same time as the burying of the paper tube 11.

As another method, a groove may be directly formed in the foamed plastic heat insulating material layer 7 instead of embedding the paper tube 11 as the space 9 for disposing the electric wire 10. In this case, the plate member 4b is temporarily attached to the frame 2, the foamed plastic is injected and foamed, and then the plate member 4b is removed. Then, for example, a groove having a square cross section of 25 mm square is cut out in accordance with the arrangement route of the electric wire 10. This work can be performed very easily because of the foam plastic insulation layer. At this time, the installation space 9 such as the outlet 12, the switch 13, and the opening 14 may be cut out and formed, and the opening may also be cut in the plate 4b. After the above operation is completed, the plate member 4b is fully attached and attached to the frame 2.

As in the present invention, when the paper tube 11 is buried in the foamed plastic heat insulating material layer 7, unlike the case where the paper tube 11 is provided in the conventional fibrous heat insulating material layer, the foamed plastic heat insulating material layer is extremely strongly reinforced. The paper tube 11 is surrounded and fixed, and does not shift even when an external force is applied. This is because the foamed plastic layer maintains its overall form even though it has local elastic deformation. For the same reason, when the space 9 for disposing the wiring equipment 8 other than the paper tube 11 is cut out by post-processing, the heat insulating material does not protrude from the surroundings.

Since the thermal insulation panel manufactured according to the present invention is constructed and used as described above, generally, the amount of the expensive foamed plastic thermal insulation material does not increase so much, and the cost does not increase significantly. And wiring work can be performed much easier and faster without reducing insulation. In addition, it is easy to select only one of the heat insulating panels for which wiring work is to be performed, and to easily use the multi-layer heat insulating material as needed.
