There are problems such as dimensional differences during construction making it difficult to properly insert the insulation material, and gaps forming where the insulation material is inserted, reducing the insulation effect.

ある。As a heat insulating material that solves this problem, a grooved foam board is known, which has many grooves on the board surface along the direction intersecting the compression direction, giving it compressibility. When manufacturing plates, there are important issues as described below.

所要の断熱性能を得ることもできないおそれがある。Generally, it is known to use a heating wire such as a nichrome wire to cut foam, but in order to manufacture the grooved foam board that is the object of the present invention, at least one side of the foam board must be cut. The width is 0.3 to 2.0 at a depth of mA-% of the plate thickness.
Since a large number of grooves of about +W size are to be provided at the same time, the known cutting method using a heating wire cannot be directly applied to the present invention. That is, when forming the above-mentioned grooves on the plate surface, once the grooves are formed to a required depth by the heated heating wire, it is necessary to pull up the heating wire and separate it from the plate surface. When the heating wire is pulled up, the foam board heated by the heating wire is bent, and this curvature causes problems such as parts of the foam board other than the regular grooves being fused, and also causes heat generation. The heating wire is easy to stretch, and when this heating wire comes into contact with the foam board and the foam board starts to melt, the middle part of the foam board melts later than the ends of both edges. It is unavoidable that the heating time will be longer, and in addition, the heating wire itself is hotter at both ends than the middle part, so by the time the middle part of the foam board has melted to the specified depth, both ends of the heating wire are hotter than the middle part. The fusing progresses further, resulting in the problem that the bottom of the groove is unduly wide. As a result, the shape of the grooves cannot be made uniform over the entire length of the product, resulting in poor appearance when used as a heat insulating material.
There is also a possibility that the required heat insulation performance cannot be obtained.

明する。Therefore, the present invention aims to completely eliminate such problems and provide a new method for manufacturing a grooved foam board that can always form desired stable grooves correctly, and which meets the technical requirements. The step is to use a heating wire placed on the synthetic resin foam board so as to intersect with the foam board, to generate heat from this heating wire and press it against the synthetic resin foam board to form grooves in the synthetic resin foam board. , the parts of the heating wire protruding from both edges of the synthetic resin foam board are cooled, and from the time the heating wire starts pressing against the synthetic resin foam board until the heating wire completes retreating from the synthetic resin foam board. The purpose of this method is to press a synthetic resin foam board against the pressing side of an intermediate hot wire to produce a grooved foam board. According to this manufacturing method, it is possible to completely prevent the synthetic resin foam board from curving and from heating the both ends of the formed grooves more than necessary, and it is possible to completely prevent the synthetic resin foam board from being heated more than necessary. A grooved foam board P in which the width of the grooves a is uniform throughout and has good heat insulation performance will be described.

ない溝付き発泡板を製造できた。In order to carry out the manufacturing method of the present invention using the apparatus configured as described above, first, as shown in FIG. Lower 6. When the heating wire 8 presses against the synthetic resin foam board P due to the fall of the support frame 6, the pressing plates 17a, 17
a is also in contact with the synthetic resin foam board P, and the synthetic resin foam board P
Press. During this operation, the heating wire 8 generates heat by being energized, and cooling air is injected from the injection pipes 18 and 18. When the support frame 6 is lowered in this state, the synthetic resin foam board P' is fused and cut by the heating wire 8 to form a groove. Next, the support frame 6 is stopped at the position shown in FIG.
If it is moved further back, the grooves of the desired depth can be formed in the synthetic resin foam board P.
′ can be formed. During this groove processing, the synthetic resin foam board P'
Since the heating wires 8 are placed under a suppressing action, the heating wires 8 are prevented from curving when retreating, and the portions 8a of the heating wires 8 that protrude from the left and right edges of the synthetic resin foam board P' are also prevented. Since the is placed under cooling, the problem that the left and right ends of the synthetic resin foam board P' are heated excessively compared to the middle part is eliminated, and the shape of the groove formed in the synthetic resin foam board I is It was possible to manufacture a grooved foam board that is stable over the entire length and does not suffer from any deformed parts such as the width of the groove expanding in a tapered manner or the bottom and both ends of the groove being unduly wider than the middle part.

である。The present invention is as described above, and has the advantage of being able to easily manufacture a grooved foam board whose width is stable over the entire depth or length of the groove and which does not reduce heat insulation performance, and the manufacturing apparatus thereof can also be easily provided. Together with this, the practical value is extremely large.

may be directly stretched, and in this case, it is desirable that the thickness of the support is approximately the same as the outer diameter of the heating wire 8.
