Description

DETAILED DESCRIPTION OF THE INVENTION The present invention connects an outdoor side member and an indoor side member facing the outdoor side member with a plurality of connecting bodies made of heat insulating materials spaced apart from each other, so that the outdoor side member, The present invention relates to a method of manufacturing a heat insulating molded material having a cavity formed inside using an indoor side member and a plurality of connecting bodies.

Conventionally, the manufacturing method for this type of insulation material is as follows:
As described in Japanese Patent Application Laid-open No. 56-59984,
manufacturing a molded material in which an outdoor side member and an indoor side member facing the outdoor side member are connected by one or more connecting walls to form a plurality of grooves opening outward;
After forming a first connecting body made of a heat insulating material by injecting and filling one of the plurality of grooves with a heat insulating material and curing it, the one or more connecting walls are cut out with a cutter or the like, and then After that, a heat insulating material is injected and filled into the other groove and cured to form a second connected body made of the heat insulating material, and a cavity is formed inside with the outdoor side member, the indoor side member and the plurality of connected bodies. A method of manufacturing a heat insulating profile has been proposed.

However, with this manufacturing method, the insulation filler is not only cut away by the connecting wall cutters, etc., but the insulation material chips are charged with static electricity during cutting and adhere to the outer surface of the mold material. Not only is it very troublesome to remove the cutting waste from the insulation material, but when the insulation material is removed, cracks and fissures occur in the insulation material, causing damage to the outdoor and indoor components made of insulation material. This also caused a decrease in the strength of connection with other members.

Furthermore, when the connecting member is to be peeled off, since the connecting member is adhered to the heat insulating material, there is a problem in that the connecting member cannot be easily peeled off even though the connecting member has lines to facilitate the removal. .

Furthermore, with this manufacturing method, the cut surface resulting from the removal of the connecting wall is exposed and the cut surface is not surface-treated, so if this surface is exposed to outside air or moisture adheres to it, this part will corrode. It was hot.

In order to avoid such corrosion defects, it is possible to apply a coating to the cut surface, but since the cut surface is exposed on the side of the cavity located inside, there is also the disadvantage that it is difficult to apply a coating. It was hot.

Furthermore, as a manufacturing method of this type of heat insulating shaped material, as described in Japanese Patent Application Laid-Open No. 53-140843, the outdoor side member and the indoor side member are manufactured separately, and both the outdoor and inner side members are By arranging them at a predetermined distance from each other over the entire length in the direction, installing a heat insulating strip sheet between the two spaced apart outdoor and inner members, and sequentially injecting and curing the heat insulating material,
A method of manufacturing a heat insulating molded material has also been proposed in which a hollow portion is formed inside by forming a plurality of connected bodies made of heat insulating materials spaced apart from each other in the vertical direction.

According to this manufacturing method, there is no cut surface formed by cutting out the connecting wall as in the above-mentioned conventional technology, so there is no problem of corrosion. Also, when injecting and filling the insulation material, it is necessary to fix the outdoor side member and the indoor side member at a predetermined distance apart, and it is also necessary to provide special fixing means for this, making the equipment complicated and expensive. There were flaws.

The present invention has been developed in view of the drawbacks of the prior art, and its purpose is to separate an outdoor member and an indoor member facing the outdoor member from a heat insulating material that is separated from each other. In the manufacture of a heat insulating molded material which is connected by a plurality of connecting bodies consisting of the outdoor side member, the indoor side member and the plurality of connecting bodies to form a cavity inside, the outdoor side member and the indoor side member are connected. When cutting the connecting wall, the connecting wall can be removed without scraping the filling insulation material, and the cut surface of the connecting wall can be covered with the insulation material that is injected and filled to form the insulation connecting body. The purpose of the present invention is to provide a method for manufacturing a heat insulating shape material that can be easily and cost-effective by eliminating the need for special fixing means for fixing the outdoor side member and the indoor side member during the manufacturing of the above-mentioned heat insulating shape material. It is an object of the present invention to provide a method for manufacturing a heat insulating material that can be manufactured at low cost.

At this time, the cut surface 21' of the connection wall 20' is covered with a heat insulating material.

Further, as shown in FIG. 3, the shapes of the outdoor member 1 and the indoor member 10 may be such that the outdoor member 1 is plate-shaped and the indoor member 10 is box-shaped in cross section.

In the above embodiments, the connecting wall is cut out using a cutter, but a pair of lines may be formed in the connecting wall, and the portion between the pair of lines may be removed by cutting.

As described above, the present invention manufactures a shape material in which an outdoor side member and an indoor side member facing the outdoor side member are connected by a plurality of connecting walls, and after cutting out the connecting walls, the outdoor side member of this shape material is A heat insulating strip sheet is installed over the indoor side member to form a cavity inside, and first and second grooves which are spaced apart from each other and open outward are sequentially formed by the cavity. Then, the first and second grooves are sequentially injected and filled with a heat insulating material and cured to form the first and second connected bodies made of the heat insulating material. The first and second grooves for forming the first and second connecting bodies are separated by a cavity formed inside and can be formed without interfering with each other. Therefore, even if the first connecting body made of a heat insulating material is formed in the first groove, the first connecting body is removed when the connecting wall is cut out prior to forming the second groove. Since the connecting wall can be removed without dripping, there is no cutting waste from the insulation material, and there is no need to remove it, making the work easy.Furthermore, it does not cause cracks or fissures in the connecting body. It is possible to obtain a heat insulating molded material with excellent heat insulation properties without reducing the connection strength between the outdoor side member and the indoor side member due to the first and second connecting bodies spaced apart from each other, and by having a hollow portion inside. .

Further, after cutting out the connecting wall, a heat insulating band-shaped sheet is installed in the inner part of the connecting wall closer to the cavity formed inside than the cut out part, so as to extend over the outdoor side member and the indoor side member. Since a groove that opens outward is formed using the outdoor side member, the indoor side member, and the heat insulating strip sheet, and the heat insulating material is injected and filled into this groove, all that is required is to inject and fill the insulating material into the groove that opens outward. The cut surface of the connecting wall can be covered by cutting, and the cut surface can be prevented from being exposed to the outside air and corroded from that part. Without adding any steps or means, it is possible to obtain a heat insulating shape material that also covers the cut surface by simply injecting and filling the heat insulating material to connect the outdoor side member and the indoor side member.

In this way, the present invention has made it possible for the first time to manufacture a heat insulating molded material having an internal cavity, for which it has been difficult to coat the cut surface of the connecting wall to prevent corrosion.

Moreover, as described above, during the production of a heat insulating material capable of covering the cut surface obtained by cutting the connecting wall, the outdoor side member and the indoor side member are connected to each other by the connecting wall or the connecting body. Since the process of cutting out the connecting wall, installing the heat insulating strip sheet, and injecting and filling the heat insulating material can be carried out, a special fixing means is provided to fix the outdoor side member and the indoor side member. There is also the advantage that there is no need for it, the manufacturing equipment becomes simple, and it can be manufactured at low cost.
