[Technical field to which the device belongs]

 The present invention relates to a heat insulating material for a house. More specifically, the present invention relates to a structure of a foamed resin board used as a heat insulating material for a building such as a house in which grooves are provided on the front surface and the back surface of a rigid foamed resin board having closed cells to provide compressibility.

[0002]

[Problems to be solved by the prior art and the present invention]

 In buildings and structures such as houses, heat insulation is usually applied to the outside such as walls, floors or ceilings to reduce heat loss and maintain an appropriate room temperature. As one of the heat insulation methods, there is known a filling method in which a heat insulating material is processed and fitted in accordance with the shape of the filling portion (fitting portion) such as floor joists in the floor portion or pillars in the wall portion. As the heat insulating material, glass wool, rock wool, expanded polystyrene board, etc. are known. Among these heat insulating materials, expanded polystyrene board is relatively hard, and its shape hardly changes even after processing, There is an advantage that high heat insulation performance can be maintained at the construction site. However, in the filling method in which the heat insulating material is fitted between columns and joists, since the expanded polystyrene is hard, the fitability is poor and the construction efficiency is reduced. On the other hand, in order to fit the heat insulating material tightly without any gaps and to increase the work efficiency, it is sufficient to cut the expanded polystyrene board accurately. Cutting with high precision according to the size and shape of the not only complicates the cutting work, but also greatly reduces the construction efficiency. If a gap is created between the heat insulating material and the structure, that part becomes a thermal weak point, and it becomes a heat bridge to increase the amount of heat loss and cause condensation as the temperature decreases. .

Therefore, in Japanese Utility Model Publication No. 56-51908, as a proposal for tightly fitting a plate-like synthetic resin foam into a construction site of a structure without a gap, the foam intersects with a direction in which the foam is compressed. A residential heat insulating material consisting of a plate-shaped synthetic resin foam provided with a number of grooves that can be compressed along the direction has been proposed. By using such a plate-shaped synthetic resin foam, , It can be tightly fitted into the construction site of the structure without any gaps.

However, the synthetic resin foam provided with the groove and provided with the compressibility disclosed in the above publication has a size slightly larger than the portion where the heat insulating material such as the space between the pillars and the space between the joists is fitted, and the filling work is performed. Since it is sometimes attached to the fitting part in a compressed state, the end part of the heat insulating material is caught by joists etc. during the filling work, and the workability to the fitting part is poor, and the heat insulating material filled by excessive compression is filled. The surface on the indoor side becomes concave or convex, and if the interior surface of the heat insulating material is filled with warping on the concave surface, the heat insulating material and floor finishing material or interior base material There is a problem in that a gap is created between them, which reduces the heat insulation effect.

On the other hand, in the board-shaped heat insulating material applied to the structure, a gap is likely to occur at the butted portion, and that portion becomes a thermal weak point, so that it becomes a heat bridge and increases the amount of heat loss. It also causes dew condensation as the temperature decreases.

[0006]

[Problems to be solved by the device]

 Therefore, the object of the present invention is to use a rigid foamed resin board to improve the workability of fitting into a work site and to create a gap that causes a large amount of heat loss, even if the dimensional accuracy is not very high. Not to provide insulation for homes.

[0007]

[Means for Solving the Problems]

 As a result of earnest studies to solve the above-mentioned object, the present inventors have provided a heat insulating material for a house that can be easily filled by providing an inclined surface parallel to the groove.

That is, according to the present invention, a plurality of grooves are alternately provided on the front surface and the back surface of a rigid foamed resin board having closed cells, so that compressibility is imparted in a direction intersecting the extending direction of the grooves. In a foamed resin board (hereinafter referred to as a compressible foamed resin board), a heat insulating material for a house characterized by forming a sloped surface by chamfering one or two side edges parallel to the groove. Is.

[0009] In the construction of a house or the like, the inclined surface is a side edge that becomes a joist or a pillar side in the fitting direction when the heat insulating material is fitted into a filling place such as a pillar space or a joist by a filling method. Is formed in order to reduce the situation of being caught on the joists and pillars, to facilitate the insertion, and to improve the working efficiency.

Therefore, the inclined surface is formed by subjecting one or two side edges parallel to the groove of the foamed resin board to chamfering. The side edges are at least filled with a heat insulating material by filling. At the time of fitting, it is necessary to form on the joist in the fitting direction or on the side edge on the pillar side, and when both opposing side edges are on the joist or pillar side, desirably both side edges. The chamfering process should be performed on the to form an inclined surface. However, even if an inclined surface is formed on any one of the side edges, when fitting it, it is necessary to first fit the side without the inclined surface first and then the other inclined surface side. The effects of the present invention can be enjoyed without any particular problem.

Further, when the heat insulating members are abutted against each other, at least one of the end faces intersecting with the groove portion of the foamed resin board is formed so that a gap is not formed between the joint portions of the heat insulating materials. It is also possible to provide a joint part on the end face. Further, although the fitting joint portion has a stepped shape, the same effect can be obtained even if various generally-known mortise joint structures are adopted as a joining means for plate members. it can.

Further, in the present invention, in order that the heat insulating material for a house can be filled and installed in a state of closely adhering to the floor finishing material or the interior base material without forming a gap, the back surface of the heat insulating material for a house ( It is necessary to regulate the total width dimension of the groove portion provided on the outdoor side to be equal to or larger than the total width dimension of the groove portion provided on the front surface (inner side). As a result, the back surface (outdoor side) of the residential heat insulating material that has been filled and compressed between columns or joists is more likely to be compressed on the back surface (outdoor side) than the front surface (indoor side). The convex surface makes it possible to perform the filling work while being in close contact with the floor finishing material and interior base material.

As described above, as a means for making the total groove width of the rear surface (outside the room) of the heat insulating material for a house equal to or larger than the total groove width of the front surface (inside the room), the number of the rear surface and the front surface is the same. In this case, a means such as forming the groove width of the back surface groove wider than the front surface is adopted, and if the groove widths of the back surface and front surface are the same, more groove areas than the front surface are used. A means for forming the back surface is adopted. The means for forming a wide groove width and the means for forming a large number of groove portions are not always limited to either one, and it is naturally possible to use them in combination.

The hard foamed resin board used for manufacturing the heat insulating material for a house of the present invention may be made of foamed polyurethane resin or polystyrene foam resin. However, the foamed resin board made of foamed polyurethane resin is a little fragile, and the corners are likely to be chipped during the filling process, and the foamed resin board made of expanded polystyrene resin by the bead foaming method has a bead fusion portion. In view of the tendency of chipping, a foamed resin board formed by using an extruded expanded polystyrene resin is desirable in the heat insulating material for a house of the present invention.
