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-mentioned product has a point 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, the present invention is to continuously supply upper and lower metal hoop materials to continuously form horizontal trapezoidal veins separately with upper and lower horizontal trapezoidal vein forming rolls, respectively. The hoop material is conveyed so as to be symmetrical vertically, and the synthetic resin stirring liquid is injected and dispersed by the synthetic resin liquid stirring machine on the uneven portion on the back side of the horizontal trapezoidal vein of the metal hoop material below to provide the heat insulating material. In the method of manufacturing, in the recess on the back side of the lower metal hoop material that has been subjected to the horizontal trapezoidal vein processing, first, the first synthetic resin liquid stirrer is injected, and immediately after that, with the second synthetic resin liquid stirrer. Synthetic resin agitation liquid is injected into the entire uneven surface of the lower metal hoop material, and immediately after the injection, the upper metal hoop material subjected to horizontal trapezoidal vein processing is conveyed from above, and the upper and lower horizontal hoop trapezoidal processed metal hoop material A top and bottom container with uneven supports that correspond to uneven parts In wherein the pressing-pressure, the upper and lower concave-convex portion is that conceive the manufacturing method of the heat insulating material is symmetrical.

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

FIG. 1 is a cross-sectional view in the traveling direction of the main part for manufacturing a heat insulating material. 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 symmetrically, 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. The bulging of the uneven portion of the upper metal hoop material 1 is caused by the pressing of the dented portion 4A on the front side of 1) and the convex contact portion 6A (correction of the bulge of the convex portion 3A on the front side of the upper metal hoop material 1). The surface of the uneven portion is corrected and 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 is a schematic cross-sectional view showing the method for manufacturing the heat insulating plate A of the present invention. The upper metal hoop material 1 is a horizontal trapezoidal vein forming roll.
Lateral trapezoidal veins are processed by 12A and 12B, and they are conveyed by the endless conveyor 8 with a supporting portion for the concave portion. Lower metal hoop material 2
Similarly, the horizontal trapezoidal vein forming rolls 12A and 12B are used to perform horizontal trapezoidal vein processing, and the endless conveyor 7 having a supporting portion for the recessed portion below conveys it.

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.

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.
