Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for manufacturing a heat insulating building board.
A groove 4 is formed on the opposing inner surface 3 of the frame 1, and then a thin flexible film 5 is laid on the frame mounting table 2 between the frames 1, and the flexible film 5 is placed on the inner side of the groove 4, then foamed resin 6 is foamed on the flexible film 5, and the foamed resin 6 is filled and hardened over the entire space between the frames 1. At the same time, the foamed resin 6 is placed inside the groove 4. flexible film 5
The present invention relates to a method of manufacturing a heat insulating building board characterized by filling and curing foamed resin 6 at the same time.

Conventional insulating building boards have been made by filling a substantially U-shaped surface material with foamed resin.

In this case, since the wall thickness of the surface material was small, the wall thickness of the foamed resin was relatively small, resulting in a loss of insulation, and because the dimensions of the surface material were fixed, wide and narrow It was impossible to create something arbitrarily.

The present invention was made in view of the drawbacks of the conventional example, and
The first object of the present invention is to lay a flexible film on a frame mounting table between frames, foam a foamed resin on the thin flexible film, and fill and harden the foamed resin over the entire space between the frames. To provide a method for manufacturing a heat-insulating building board with excellent heat-insulating properties, by minimizing the thickness of the flexible film portion, which has poor heat-insulating properties, and maximizing the wall thickness of the foamed resin portion, which has excellent heat-insulating properties. The second purpose is to foam the foamed resin on a flexible film between the frames placed opposite each other on the frame mounting table, fill and harden the foamed resin between the entire frames, and then fill and harden the foamed resin between the frames. By filling and hardening foamed resin together with a flexible film in the groove, the interval between the frames can be arbitrarily set, and by foaming and hardening the foamed resin between them, any width from wide to narrow can be created. An object of the present invention is to provide a method for producing a heat-insulating building board.

The present invention will be described in detail below according to illustrated embodiments.

The frame 1 includes a left side frame T and a right side frame 8.

To explain the left frame body 7, a left horizontal piece 10 extends outward to the left from the upper end of the left frame body 9 over the entire length of the left frame body 9, and an opening groove 11 that roughly opens leftward in the left frame body 9.
A groove 4 is formed in the opposing inner surface 3, which is the right side surface of the left frame body 9, over the entire length of the left frame body 9.

To explain the right frame body 8, the height of the right frame body 12 is lower than the height of the left frame body 9 by 101 left horizontal pieces. The piece 13 extends over the entire length of the right frame body 12, and a groove 4 is formed in the opposing inner surface 3, which is roughly the left side surface of the right frame body 12, over the entire length of the right frame body 12.

The flexible film 5 is thin and made of plastic.

The foamed resin 6 is made of, for example, hard foamed urethane resin.

The frame mounting table 2 is the lower mold of the double conveyor, and has a recess 14 with an upper opening, and the inner side surface of this recess is formed into a stepped shape to match the frame 1. It is attached on the conveyor section 15 for transportation.

The double conveyor has an upper mold conveyor 16 disposed above the frame mounting table 2, and the right side of the lower surface of the upper mold conveyor 16 is formed to have a thicker wall.

Therefore, the left side frame 7 and the right side frame 8 are arranged to match the stepped portion 17 of the recess 14 of the frame mounting table 2, and then the flexible film 5 is laid on the frame mounting table 2. At the same time, the end portion of the flexible film 5 covers the entire length of the groove 4 in the longitudinal direction.

Then, just before the frame 1 enters the upper die conveyor 16, the flexible film 5 is filled with foamed resin 6.

This foamed resin 6 is foamed and hardened while passing through the upper mold conveyor 16.

Since the foamed resin 6 is restrained by the frame 1, the frame mounting table 2, and the upper mold conveyor 16, it is molded and hardened in accordance with these shapes.

Therefore, the foamed resin 6 is filled and hardened over the entire space between the frames 1, and the flexible film 5 is pushed into the groove 4.
Fill inside and harden.

In this case, since the deep part of the groove 4 is wider than the opening, when the foamed resin 6 hardens, the part filled with the foamed resin 6 does not fall out from the groove 4, and the left and right sides The frame 1.8, the foamed resin 6, and the flexible film 5 are reliably integrated into a heat-insulating building board A, which is discharged from the double conveyor.

This insulation building board A has a right insertion horizontal piece 13 inserted into the opening groove 11 of another insulation construction board A arranged adjacently, and a left side horizontal piece 10 is superimposed on the right insertion horizontal piece 13. It is used as wall and ceiling materials.

In this case, since the thickness of the flexible film 5, which has poor thermal insulation properties, becomes small, the thickness of the foamed resin 6, which has excellent thermal insulation properties, becomes smaller, and the insulation properties of the insulation building board A can be improved. It is.

Furthermore, since the frame 1 is divided into a frame 7 for the left side and a frame 8 for the right side, a heat insulating building board A of any width can be obtained by changing the spacing between these frames.

In this case, it is necessary to change the width of the recess 14.

Furthermore, in this case, by increasing the width of the insulation building board A, it is possible to reduce material costs and improve construction efficiency.
