Abstract
Description
本発明は、建造物の床、壁、天井等の断熱された面に設ける点検口を覆うための、断熱機能を有する点検口蓋に関する。 The present invention relates to an inspection port lid having a heat insulating function for covering an inspection port provided on a thermally insulated surface such as a floor, wall, or ceiling of a building.
住宅をはじめ、オフィスビル、工場等の建造物は、温熱環境改善および省エネルギーを目的として床、壁、天井を１０ｃｍ以上の厚さの断熱材で覆うのが一般的である。 Buildings such as houses, office buildings, factories and the like generally cover floors, walls, and ceilings with a heat insulating material having a thickness of 10 cm or more for the purpose of improving the thermal environment and saving energy.
一方、床、壁或いは天井には、補修時、管理点検時等のメンテナンスに利用するための点検口が設けられている。ここで、点検口の大きさは人が出入りできるように約４０ｃｍ四方あり且つ複数個設けられているため、熱損失が非常に大きい。この問題を解決するために、特許文献１は天井に設けた開口部に点検蓋を開閉自在に設け、この点検蓋の上方に、樹脂発泡体内に真空断熱材を挟み込んだ蓋体を配置する構成を提案している。 On the other hand, the floor, wall, or ceiling is provided with an inspection port for use in maintenance such as during repairs and management inspections. Here, the size of the inspection port is approximately 40 cm square so that a person can go in and out, and a plurality of inspection ports are provided, so that heat loss is very large. In order to solve this problem, Patent Document 1 has a configuration in which an inspection lid is provided in an opening provided on the ceiling so that the inspection lid can be freely opened and closed, and a lid body in which a vacuum heat insulating material is sandwiched between resin foams is disposed above the inspection lid. Has proposed.
しかし、特許文献１では樹脂発泡体内に真空断熱材を挟み込んだ蓋体の厚みが厚いため、点検する場合には蓋体を持ち上げて開口部から取り外さなければならず点検作業が面倒である。 However, in patent document 1, since the thickness of the lid body in which the vacuum heat insulating material is sandwiched between the resin foams is thick, when inspecting, the lid body must be lifted and removed from the opening, which is troublesome.
上記課題を解決するため本発明に係る点検口蓋は点検口にヒンジを介して開閉自在に取り付けられ、樹脂パック内にガラス繊維が減圧状態で充填された真空断熱材の外側を別の断熱材または遮音シートで覆って複合断熱材とし、この複合断熱材自体を前記点検口蓋とするか、或いは複合断熱材を点検口蓋の裏面に取り付けた。 In order to solve the above-mentioned problems, the inspection port lid according to the present invention is attached to the inspection port through a hinge so as to be freely openable and closable, and the outside of the vacuum heat insulating material filled with glass fiber in a reduced pressure state is provided with another heat insulating material or It covered with the sound insulation sheet, it was set as the composite heat insulating material, and this composite heat insulating material itself was made into the said inspection opening cover, or the composite heat insulating material was attached to the back surface of the inspection opening cover.
本発明に係る点検口蓋の作製方法としては、１枚または複数の真空断熱材を、相互に間隔を保って枠体内に配置し、ここへ樹脂（発泡樹脂を含む）を流し込んで固化させる方法や、樹脂製の偏平ボックス状の収納体に真空断熱材を挿入する方法が考えられる。 As a method for producing the inspection mouth cover according to the present invention, one or a plurality of vacuum heat insulating materials are arranged in the frame body while keeping a space between each other, and a resin (including a foamed resin) is poured into the frame to be solidified. A method of inserting a vacuum heat insulating material into a flat box-shaped housing made of resin can be considered.
本発明の点検口蓋は、真空断熱材を使用しているため天井の断熱材と比較して薄く形成することができ、点検口蓋を開閉する際に、開閉の邪魔になることがなくなる。 Since the inspection port lid of the present invention uses a vacuum heat insulating material, it can be formed thinner than the ceiling heat insulating material, and does not obstruct the opening and closing when the inspection port lid is opened and closed.
また、真空断熱材の外側を更に断熱材で包み込んだ場合には、更に高い断熱効果が期待でき、真空断熱材の外側を遮音シートで包み込んだ場合には、点検口を介して騒音が伝わることを抑制できる。 In addition, if the outside of the vacuum insulation is further wrapped with heat insulation, a higher heat insulation effect can be expected, and if the outside of the vacuum insulation is wrapped with a sound insulation sheet, noise will be transmitted through the inspection port. Can be suppressed.
以下に本発明の実施の形態を添付図面に基づいて説明する。図１は本発明に係る点検口蓋の断面図であり、天井板１の裏面（上面）は断熱材２で覆われている。この天井板１の一部に点検口３が設けられている。この点検口３は、野縁４に取り付けられた点検口枠５と天井板１の裏面に載せられた断熱材（グラスウールマット）２を遮るための木枠６とから構成されている。 Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of an inspection port lid according to the present invention, and the back surface (upper surface) of the ceiling board 1 is covered with a heat insulating material 2. An inspection port 3 is provided in a part of the ceiling plate 1. The inspection port 3 includes an inspection port frame 5 attached to the field edge 4 and a wooden frame 6 for blocking the heat insulating material (glass wool mat) 2 placed on the back surface of the ceiling board 1.
前記点検口枠５には点検口蓋７の一端がヒンジ１１を介して開閉自在に取り付けられている。点検口蓋７の裏面には、複合断熱材８が取り付けられている。この複合断熱材８は真空断熱材９とこの真空断熱材９を包む外側機能材１０からなる。 One end of an inspection port lid 7 is attached to the inspection port frame 5 through a hinge 11 so as to be freely opened and closed. A composite heat insulating material 8 is attached to the back surface of the inspection port lid 7. The composite heat insulating material 8 includes a vacuum heat insulating material 9 and an outer functional material 10 that wraps the vacuum heat insulating material 9.
前記真空断熱材９はバリヤ性の高いプラスチックフィルムからなる樹脂パック内に無機繊維（ガラス繊維）が減圧状態で充填され、また前記外側機能材１０は繊維系断熱材、樹脂系断熱材または遮音シートのいずれかとする。 The vacuum heat insulating material 9 is filled with an inorganic fiber (glass fiber) in a reduced pressure state in a resin pack made of a highly barrier plastic film, and the outer functional material 10 is a fiber heat insulating material, a resin heat insulating material or a sound insulation sheet. Either.
前記複合断熱材８の作り方は、樹脂系断熱材の場合には、成形型内に真空断熱材９をセットし、樹脂を流し込んで固化させることにより、真空断熱材９の全面を外側機能材１０としての樹脂層で被覆する。 In the case of a resin-based heat insulating material, the composite heat insulating material 8 is prepared by setting a vacuum heat insulating material 9 in a mold, and pouring the resin into a solid, thereby solidifying the entire surface of the vacuum heat insulating material 9. Cover with a resin layer.
成形型の代わりに点検口蓋７の一面側に真空断熱材９をセットし、樹脂系断熱材を点検口蓋７と真空断熱材９との上に盛り付けるようにして一体化してもよい。 Instead of the mold, a vacuum heat insulating material 9 may be set on one surface side of the inspection port lid 7, and a resin heat insulating material may be integrated on the inspection port lid 7 and the vacuum heat insulating material 9.
また繊維系断熱材で真空断熱材９を覆うには、真空断熱材９の外側に繊維系断熱材を貼り付け、遮音シートで真空断熱材９を覆うには、袋状にした遮音シート内に真空断熱材９を入れ込むかテープなどで貼り付けることで一体化する。 In order to cover the vacuum heat insulating material 9 with the fiber heat insulating material, a fiber heat insulating material is attached to the outside of the vacuum heat insulating material 9, and to cover the vacuum heat insulating material 9 with the sound insulating sheet, It integrates by putting in the vacuum heat insulating material 9 or sticking with a tape etc.
図２は別実施例に係る点検口蓋の断面図であり、この実施例では、木枠６の上端開口に蝶番１１を用いて点検口蓋７の一端側を開閉自在に取り付け、下方の点検口枠５には従来型の点検口蓋１２を設けている。本例の形態は、寒冷地用、冷凍室用等、高断熱性を必要とする箇所に好適であり、多少、断熱材が厚くなってもメンテナンス作業を支障なく実施することができる。 FIG. 2 is a cross-sectional view of an inspection port lid according to another embodiment. In this embodiment, a hinge 11 is attached to the upper end opening of the wooden frame 6 so that one end side of the inspection port lid 7 can be freely opened and closed. 5 is provided with a conventional inspection lid 12. The form of this example is suitable for places that require high heat insulation, such as for cold districts and freezer compartments, and even if the heat insulation becomes somewhat thick, maintenance work can be carried out without hindrance.
図３は、本発明の点検口蓋の別態様を示す斜視図である。この実施例では、底部１３と開口部１４を有する偏平ボックス状の樹脂製箱体からなる枠体１５に、真空断熱材９を挿入し、開口部１４は蓋となる樹脂材１６で封鎖する。枠体１５の内壁と真空断熱材９との間には発泡体を充填しても良い。本例によって点検口蓋を製造すれば、従来の製品に比較して薄く撓みにくく、かつ高断熱性とすることができる。 FIG. 3 is a perspective view showing another aspect of the inspection palate according to the present invention. In this embodiment, a vacuum heat insulating material 9 is inserted into a frame 15 made of a flat box-shaped resin box having a bottom 13 and an opening 14, and the opening 14 is sealed with a resin material 16 serving as a lid. A foam may be filled between the inner wall of the frame 15 and the vacuum heat insulating material 9. If an inspection mouth cover is manufactured by this example, it can be made thin and hard to bend compared with the conventional product, and can be made high heat insulation.
