Description

TECHNICAL FIELD The present invention relates to a method of using a heat insulating material used for a roof member, a wall member, and a floor material of a building.

[Conventional technology]

Conventionally, as seen in USP 3,117,171, a single synthetic resin liquid stirrer was injected, and a horizontal trapezoidal vein of metal hoop material was manufactured at the top. Moreover,
The bottom surface was a flat product.

[Problems to be solved by the invention]

In usp3, 117, 171, the lower metal hoop material (paper, film) is flat, the upper metal hoop material is processed into a horizontal trapezoidal vein, and synthesized on the lower metal hoop material from a synthetic resin liquid stirrer. The resin stirring liquid was injected and sprayed.

In the above method, voids were formed in the convex portions on the back side of the upper metal hoop material which was processed into a trapezoidal vein. Further, if excessive injection is performed to eliminate voids, the uneven surface on the front side of the trapezoidal-processed metal hoop material causes abnormal expansion due to foaming pressure and internal heat generation.
In order to prevent "swelling", even if the upper conveyor was pressed with a conveyor having an uneven surface corresponding to the uneven surface of the horizontal trapezoidal vein processing of the upper metal hoop material, it could not be repaired. Further, the above product has a drawback that "warpage" occurs on the flat portion side of the lower surface.

[Means of solution]

As a result of intensive research to solve the above problems, the present invention has been achieved.

That is, according to the present invention, the upper and lower metal hoop materials are continuously supplied, and horizontal trapezoidal veins of the same type or non-same type are continuously formed separately by upper and lower horizontal trapezoidal vein forming rolls. The processed upper and lower metal hoop materials are conveyed vertically opposite to each other, and the synthetic resin liquid stirring machine injects and sprays the synthetic resin liquid stirring liquid onto the uneven parts on the back side of the horizontal trapezoidal vein of the lower metal hoop material. And a method of manufacturing a heat insulating material,
First, the first synthetic resin liquid stirrer was used to inject into the recessed portion on the back side of the lower metal hoop material, which was subjected to the horizontal trapezoidal vein processing, and immediately thereafter, the second synthetic resin liquid stirrer was used to insert the metal hoop material below. Synthetic resin agitation liquid is poured over the entire surface of the concavo-convex part, and immediately after the pouring, the upper metal hoop material with horizontal trapezoidal vein processing is conveyed from above, and the unevenness corresponding to the concavo-convex part of the upper and lower horizontal type trapezoidal vein processed metal hoop material is provided. The present invention contemplates a method of manufacturing a heat insulating material in which upper and lower concavo-convex portions are symmetrical, which is characterized by pressing and pressing with upper and lower conveyors having supporting portions.

In this case, it is preferable that the horizontal unevenness of the lower metal hoop material is equal to or larger than the horizontal unevenness of the upper metal hoop material. This is because if the irregularities of the upper metal hoop material are larger than the irregularities of the lower metal hoop material, it is difficult to distribute the injection amount of the synthetic resin liquid, and voids of the heat insulating material occur in the upper corners.

The present invention will be described with reference to the drawings.

FIG. 1 is an asymmetrical cross-sectional view in the case where the concave and convex portions in the traveling direction of the main part for manufacturing the heat insulating material are the same. Similar to the upper metal hoop material 1 subjected to the horizontal trapezoidal vein processing, the lower metal hoop material 2 subjected to the horizontal trapezoidal vein processing is positioned vertically asymmetrical, and the heat insulating material B is interposed therebetween. The front side convex portion 3A (rear side concave portion) and the front side concave portion 4A (back side convex portion) of the upper metal hoop material are the concave portion supporting portion 5A (the upper metal hoop material) of the upper concave portion supporting endless conveyor 8. 1 bulge correction of the concave portion 4A on the front side and the convex contact portion 6A (the convex portion on the front side of the upper metal hoop material 1)
The bulging of the uneven portion of the upper metal hoop material 1 is corrected by the pressing of (3A swell correction), and the surface of the uneven portion is flattened.

Similarly, the front side convex portion 3B (back side concave portion) and the front side concave portion 4B (back side convex portion) of the lower metal hoop material 2 are the same as the concave portion supporting portion 5B of the lower concave portion supporting portion-equipped endless conveyor 7 described below. Convex contact part
By pressing 6B, the bulging of the uneven portion of the metal hoop material 2 below is corrected and the surface of the uneven portion is flattened.

FIG. 2 shows a method for manufacturing the heat insulating plate A of the present invention. It is a cross-sectional schematic diagram in case the horizontal uneven | corrugated part of the metal hoop material of the upper and lower sides is the same type and asymmetric. The upper metal hoop material 1 is subjected to horizontal trapezoidal vein processing by the horizontal trapezoidal vein forming rolls 12A and 12B, and is conveyed by the endless conveyor 8 with the upper recessed portion supporting portion. The lower metal hoop material 2 is also processed by the horizontal trapezoidal vein forming rolls 12C and 12D in the same manner, and the endless conveyer 7 with the recessed portion support portion below is also provided.
Transported by.

The heat insulating material B is made by the synthetic resin liquid agitators 9 and 10.
First, the synthetic resin stirring liquid 11A poured from the first synthetic resin liquid stirrer 9 is poured and filled in the recess 3B on the back side of the lower metal hoop material, and the skew is generated in association with the conveyor speed, and the end portion
When it comes to (left), turn back with the limit switch and continue injection into the next recess. In the same manner, continue to inject while diagonally moving, and at the end (right), turn back with the limit switch and move to the next recess and continue injecting. In this way, the left end portion and the right end portion are traversed (repeated repeatedly), and the recesses are successively injected and filled.

A second synthetic resin liquid stirrer 10 is installed at a distance of 1 m to 2 m from the first synthetic resin liquid stirrer 9, and traverses the concavo-convex portions 3B and 4B on the back side of the lower metal hoop material (repeated crossing).
While spraying on the entire surface.

The interval between the first synthetic resin liquid stirrer and the second synthetic resin liquid stirrer is set so that the synthetic resin stirrer injected from the first stirrer is
This is because it is desirable for manufacturing the heat insulating plate that 11A is placed on the synthetic resin stirring liquid 11B injected from the second stirrer before the gelation (resinification) is started.

FIG. 3 shows a cross-sectional view when the uneven portion of the horizontal trapezoidal vein of the upper metal hoop material 1 is smaller than the uneven portion of the lower metal hoop material 2.

The synthetic resin used in the present invention is rigid polyurethane foam or phenol resin.

〔effect〕

Since the first and second synthetic resin liquid agitators were separately injected and filled in two times, voids due to insufficient filling disappeared. In addition, since the concave and convex supporting portions and the convex contact portions were provided on the upper and lower conveyors, a heat insulating plate A having a flat surface with uneven portions having no bulging was obtained.
