Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a folded plate-shaped insulating metal plate. Furthermore, EII #shi< is made by laminating and integrating a metal plate with a folding structure with a desired pitch and a resin foam sheet, and it is a beautiful folding plate that does not distort even if left for a long period of time. Continuous manufacturing method section of plate.

In recent years, folded steel plates with excellent bending strength, so-called keystone plates, have come to be used as flooring, ceiling and roofing materials in steel-framed buildings. A special stone board is a steel material that fits over the nest as a frame, and a surface material or concrete layer is provided on the top surface to form a ceiling, etc.
This is also because the ceiling has insufficient electrical insulation properties, poor sand heat retention, and condensation tends to occur on the underside of the keystone board.Recently, tree foam has been integrated into the keystone board as an ll1r heat material. It is divided so that it can be used for various purposes. The above-mentioned laminate is usually manufactured by laminating and integrating a foamed sheet made of polyethylene or the like and a flat steel plate, so-called steel plate coil, with adhesive or heat fusion, and then sold as a cough footwear. Layer O-# was produced by supplying it to a flaw forming machine and folding it into a folded plate shape.

However, the production of such folded plate-shaped insulating steel plates requires folding of thick laminates! Since it is ill, it is difficult to form the corners, and the product has the disadvantage that To-oil from the folding plate JLA adheres to the product. Furthermore, in the folded insulating steel plate with a value pitch of 40 mm and 1 degree, there is a lot of distortion in the resin foam when bending, and it is neglected.
There is a drawback that the heat insulating steel plate becomes distorted along the yam direction toward the resin foam as time passes after manufacturing. Therefore,
In the case of temporary pitches, it is usually necessary to manually glue pre-prepared bar-convex softwood foam onto the stone slope, and continuous production was difficult.

This invention was developed as a result of intensive research to solve these drawbacks, and was developed by providing a foam sheet with linear grooves for folding at a predetermined distance. A lamination method has been developed in which a grooved self-foamed sheet having a large number of folded aJ@ linear grooves parallel to the longitudinal direction on one or both sides is fed in the direction of the yam to form the linear grooves of the grooved foamed sheet. Then, the uneven foam is folded one after another to form an uneven foam, and the uneven foam is combined with a continuously supplied metal plate having a new structure using a flat layer suppression mold, and the uneven foam is formed using adhesive or heating. The gist of the present invention is a continuous manufacturing method for a folded plate-shaped insulating metal plate, which is characterized by fitting and bonding a metal plate with a new plate structure and a metal plate having a new plate structure.

This invention will be further explained below with reference to the drawings.

FIG. 1 shows a specific example of the continuous manufacturing method of the present invention. First, in order to sequentially bend the grooved self-foamed sheet (8) having a large number of linear grooves for bending parallel to the longitudinal direction, the sheet is passed through a folding roller (roller) in parallel to the longitudinal direction. The roller (roller) consists of two rolls with concave and convex portions joined together, and the concave and convex portions are installed so as to be bent along the linear grooves of the grooved foam sheet c2). Therefore, the grooved foam sheet (2) is the tth! As shown in WJE, the folding is suppressed and bent into an uneven shape according to the linear grooves, and an uneven foam (6) is continuously obtained. Next, the concave-convex foam (@ is the press type for fitting), which is transferred to the press roller for fitting (?).
At the same time, a metal plate (2) having a folded plate structure prepared in advance is continuously supplied. Adhesive is applied to the mating surface of the metal plate (6) by an adhesive spray (9) before supply.

Therefore, the uneven foam (a and the metal plate 61) are continuously fitted and laminated into one piece as shown in FIG. 3, and the desired folded plate-shaped insulating steel plate is continuously produced. 1st I! Grooved foam sheet in each process E of a - 1st convex soft fin foam (8
), the cross section of the metal plate (2)■ of the new version structure and the folded version soft insulation steel plate - is shown in ``4. i,... and ding@E are shown.

Various thermoplastic resins are used as the resin for this grooved foam sheet of paulownia wood, specifically polyethylene, polypropylene, polyethylene, styrene-maleic anhydride copolymer, polyvinyl ethylene-polymerizate, etc. Acid-vinyl copolymers, polyurethanes, etc. are used. The appropriate apparent thickness of the grooved foam sheet is about 2 to 1 effi, and the depth of the linear grooves depends on the thickness of the foam sheet, but is usually 1 to 6 am.

The linear grooves of the grooved foam sheet may be provided on either one side of the foam sheet, or may be provided on both TIKs. Normally, it is better to have both ICEs [if the thickness of the girder is thick, it is preferable to use the groove pattern of the beam]
If it is thin, it is preferable to adopt a - pattern.

In addition, the pattern (c) can be applied to thick foam sheets.

In addition, random patterns such as k, tS
Patterns having grooves on one side as shown in Reference and No. 2 @, and the various patterns described above can also be selected depending on the manufacturing conditions.

An example of a preferred method for producing a grooved foam sheet is shown in FIG. 9. First, a long resin foam sheet (1) is passed through a roller (4) with parallel E1m-shaped grooves in the longitudinal direction. . The linear groove forming roller 44) E has a presser foot with a circumferential shape 1c.
*It takes zero seconds to take out the product, and the protrusions are heated to at least a temperature higher than the softening point of the resin foam sheet. Since the resin foam sheet (1) passes while being pressed by the presser strips, a grooved foam sheet (2) having a large number of linear grooves (2) parallel to the longitudinal direction is obtained.

By providing presser protrusions in various patterns on the roller (4), the grooves in the various patterns described above can be formed. According to this method, since the grooved self-foamed sheet can be obtained continuously, it can be connected in series to the continuous production method of folded plate-shaped insulating metal plates of the present invention.

As the metal plate having a folding plate structure used in this invention, various known keystone plates produced by a roll forming machine for folding plates can be used. The normal thickness of these is approximately 6.1 to 6 mm. In addition, the pitch interval of the unevenness is 80
~46.- is appropriate.

In this WAE, the means for sequentially folding the grooved foam sheet is, for example, a pair of folding suppression rollers shown in the embodiment. This bending press roller may be made of at least an uneven roll that can be bent into a desired shape along the linear grooves of the grooved foam sheet. It is preferable to use rollers with a clearance corresponding to the thickness of the grooved foam sheet.Also, it is possible to provide several of the above-mentioned bending suppression rollers and fold them one after another.Also, with a fixed folding formwork, Can it be folded in sequence?

The uneven foam and the metal plate having the folded plate structure may be laminated and integrated using an adhesive or heat fusion.

In the case of thermal fusion, the foamed sheets are fused by heating the metal plate.

In the folded insulating metal plates obtained by the manufacturing method of the present invention, not only the long pitch but also the short pitch ones have almost no distortion left in the foam when folded, and can be stored for a long time. Furthermore, according to the manufacturing method of the present invention, the a-rule for folding plates does not cause distortion unlike conventional products. The foam part E of the resulting insulating metal plate is difficult to adhere to, as is the case with molding machines.
It is beautiful with no oil adhesion like conventional products, and there is no need for a drainage process. Therefore, the manufacturing method of the present invention is advantageous in the continuous production of folded insulating metal plates with various pitches, and in particular, the continuous production of folded insulating metal plates with E@pitch can be carried out efficiently, and the production speed is also excellent. ing.
