Description

  The present invention relates to a heat insulating material fixing member and a tile roof outer heat insulating method using the heat insulating material fixing member, and more specifically, a heat insulating material having good workability, excellent durability, easy repair and reform, and easy disposal and recycling. The present invention relates to a fixing member and a heat insulation method outside a tiled roof using the fixing member.

  Conventionally, in a detached house, the roof space part under the roof may be used as a loft or a storage space, and roof insulation is necessary as a measure against heat and cold.

  As such a roof insulation method, an inner heat insulation method in which a heat insulating material is sandwiched between rafters and an outer heat insulation method in which a foamed polystyrene molded product molded in accordance with the shape of a tile is fixed with an adhesive, It can be said that the latter outer insulation method is superior for the following reasons.

(1) As a measure to prevent tiles from scattering due to strong winds, the specification is that all tiles are fixed to the base plate with nails. However, if the base plate rots due to condensation, the nails will not work. Therefore, in order to maintain the performance of the roof over a long period of time, it is necessary to prevent condensation of the field board with a heat insulating material.

(2) As a countermeasure against water leakage from the roof, it is common to lay a waterproof sheet such as asphalt roofing or rubber through roofing on a field board. However, when these sheets are thermally deteriorated, performance as a waterproof sheet cannot be expected. Therefore, it is necessary to prevent thermal deterioration of the waterproof sheet with a heat insulating material.

As for the outer heat insulation method, for example, a resin foam sheet is attached on a support plate having the same corrugated surface as the roof tile, and a plurality of holes are formed, and the resin foam sheet is attached through the holes. There has been proposed a method in which a resin foam sheet that follows the corrugated shape of the support plate by suction is attached to a roof tile with an adhesive (for example, see Patent Document 1).
JP-A-9-151571 (FIGS. 1 and 2)

  However, the method of attaching the roof tile and the resin foam sheet as described above requires a support plate having the same corrugated shape as that of the roof tile, and a suction device for attaching the resin foam sheet to the support plate. In addition, since a process of bonding to the roof tile with an adhesive is required, not only the operation becomes extremely complicated, but also an increase in equipment cost is inevitable.

  In addition, there is a problem with the durability of the adhesive, and since the resin foam sheet is bonded to the roof tile, it does not follow the expansion and contraction of the resin foam sheet. In addition, the sheet may be peeled off from the roof tile. Furthermore, depending on the shape of the roof tile, it may be difficult to attach the resin foam sheet, which limits the degree of freedom of the roof tile shape.

  Furthermore, repair and renovation are not easy, and when it is discarded or recycled after use, it is necessary to separate the heat insulating material from the roof tile, and disposal and recycling are not easy.

  In view of such circumstances, the present invention solves the above-described problems of the prior art, and by using a specific heat insulating material fixing member to lay a heat insulating material on a waterproof sheet and fix a roof tile, an expensive suction device is provided. And no complicated bonding process is required, and a wide range of rationalization and labor savings are achieved. Adhesive is not used, so the insulation is peeled off from the roof tile due to expansion / contraction of the insulation and deterioration of the adhesive. In addition, since the roof tile and the heat insulating material are only physically fixed by nails or the like, the heat insulating material fixing member and the fixing member which are easy to repair and renovate and which are easy to dispose and recycle are used. The purpose is to provide a heat insulation process outside the tiled roof.

  The present invention has been made in order to achieve the above object, and claim 1 of the present invention includes a roof tile supporting portion composed of a bulging portion and one or both sides of the lower portion in a direction substantially perpendicular to the length direction. The heat insulating material fixing member includes an extended heat insulating material supporting portion.

  According to a second aspect of the present invention, there is provided a heat insulating material fixing member according to the first aspect in which a tile engaging portion is provided in the tile support portion.

  According to a third aspect of the present invention, there is provided the heat insulating material fixing member according to the first or second aspect, wherein a heat insulating material engaging portion is provided on the side wall and / or the heat insulating material supporting portion of the bulging portion forming the roof tile supporting portion. .

  A fourth aspect of the present invention includes the heat insulating material fixing member according to any one of the first to third aspects, wherein a drainage groove is provided on the back surface in a direction substantially perpendicular to the length direction.

  A fifth aspect of the present invention includes the heat insulating material fixing member according to any one of the first to fourth aspects, which is made of a foamed synthetic resin.

  A sixth aspect of the present invention includes the heat insulating material fixing member according to the fifth aspect, wherein the foamed synthetic resin is made of a polystyrene resin.

  A seventh aspect of the present invention includes the heat insulating material fixing member according to the fifth aspect, wherein the foamed synthetic resin is made of a polypropylene resin.

  Claim 8 of the present invention includes the heat insulating material fixing member according to any one of claims 5 to 7, wherein the expansion ratio is 2 to 10 times.

  A ninth aspect of the present invention includes the heat insulating material fixing member according to any one of the fifth to eighth aspects, wherein the expansion ratio is 2 to 3 times.

A heat insulating material is arranged on the top, and a tile roof external heat insulating method characterized in that a tile is fixed to a tile support portion formed of a bulging portion of the heat insulating material fixing member.

  Since the present invention uses a fixing member to fix the heat insulating material and the tile, the support plate having the same corrugated shape as the tile required for bonding the tile and the heat insulating material, and for attaching the heat insulating material to the support plate A suction device and a process of attaching the heat insulating material to the roof tile with an adhesive are not required, and a great rationalization and labor saving are achieved.

  Further, since the present invention does not use an adhesive, it is not affected by the durability of the adhesive, and therefore the durability of the heat insulating structure can be greatly improved.

The tile engaging portion is provided so that the hook portion of the tile is hooked. In addition, it is preferable to provide a heat insulating material engaging portion on the side wall of the bulging portion that forms the roof tile supporting portion, the heat insulating material supporting portion, or both, because it is easy to dispose the heat insulating material on the heat insulating material supporting portion. In this case, the engaging portion may be an engagement by unevenness, an engagement by pressure bonding, etc., but a convex portion is provided on the side wall of the bulging portion, and an elastic deformation is used without providing a concave portion in the heat insulating material.
