部まで発泡体を完全に充填するようにしていた。Conventionally, when manufacturing this type of heat insulating board, a foamable synthetic resin material was injected and foamed as a heat insulating material because it has excellent heat insulating effect, is strong, and can be foamed.
The inside of the space formed by the frame and front and back materials is filled with synthetic resin foam as a heat insulating core material, and the self-adhesive properties of the foam are utilized to integrally mold the frame and front and back materials. ing. In such conventional methods, air vent holes are provided at the corners of the four surrounding frames to prevent air from forming inside the space, especially at the four corners, in order to prevent the formation of unfilled areas of the foam inside the space formed by the frame and front and back materials. By letting the air escape to the outside through the air vent holes, the foam was completely filled to the corners.

That is, the present invention injects a foamable synthetic resin material into the space formed by the four-periphery frame and the front and back materials, causes it to foam, and then fills the space entirely with the synthetic resin foam to produce the entire heat insulating board. In this case, an injection hole is provided in the frame, and all of the breathable shielding material is fixed inside the injection hole, with its upper end fixed and its lower end movable, and attached to the inner surface of the frame, and the front and back surfaces of the frame This method of manufacturing a heat insulating board is characterized in that a reservoir groove is formed in a portion near the joint end of the material, and a foamable synthetic resin material is injected into the entire space through the injection hole to cause foaming.

2) to cover the upper and lower openings of the frame (1). To attach the front and back materials (2) to the entire frame, it is also possible to place the front and back materials (2) on the frame and attach the terminal parts of the front and back materials with attachments such as nails or rivets. In addition, as shown in Figures 1 to 3, a step equal to the thickness of the front and back materials (2) is
), place the end part of the front and back materials (2) on this part, and press the frame (1) and the front and back materials (2) with a press machine (not shown), and press the foaming material. Synthetic resin material (lily) is injected into the outer shell and foamed, and the outer shell space is filled with foam (11).
The frame (1), front and back materials (2), and foam (3) can also be integrally molded. The shape of the heat insulating board is determined by how the frame (1) is assembled, and is not limited to a rectangular shape as in this embodiment, but can be applied to any polygonal shape.
