Description

本発明は、建築物の部材間に施工される断熱材の支持部材、および施工法に関する。   The present invention relates to a support member for a heat insulating material constructed between building members, and a construction method.

例えば木造住宅の床部位の断熱構造においては、様々な形状の受け金物を根太あるいは大引き等の部材上部に設置し、断熱材を支持することが一般的である。また、部材間に支持部材を架け渡すことで断熱材を支持する方法もある。具体的には、例えば特公昭５６−１９４２４号では、Ｚ型の金物を根太に設置し断熱材を支持する方法を提案しており、また特開２００３−３０７０２８号では、根太・大引き間に弓状に湾曲した支持部材を設置する方法を提案している。
特公昭５６−１９４２４号公報 特開２００３−３０７０２８号公報 For example, in a heat insulating structure of a floor portion of a wooden house, it is common to install a metal receiving member of various shapes on the top of a member such as a joist or a large pull to support the heat insulating material. There is also a method of supporting the heat insulating material by bridging a support member between the members. Specifically, for example, Japanese Patent Publication No. 56-19424 proposes a method of installing a Z-type hardware on a joist to support a heat insulating material. A method of installing a support member curved in an arc shape is proposed.
Japanese Patent Publication No.56-19424 Japanese Patent Laid-Open No. 2003-307028

しかし、特公昭５６−１９４２４号の方法では、断熱材の中心部を支持することができず、曲げ剛性の小さい断熱材を施工する場合、断熱材の撓みによって床材との間に隙間が生じ、冷気がこの隙間に侵入した場合に、断熱性能の低下をきたすこととなる。一方、特開２００３−３０７０２８号では、部材間に支持部材を架け渡して支持しているため、曲げ剛性の小さい断熱材を施工しても床材との間に隙間は生じないものの、部材寸法や部材間隔等の違いにより部材間の内法寸法が変わった場合、対応することができない。また、いずれの場合でも、部材上部に受け金物が設置されるため、歩行時に金具と床材が擦れ合って軋み音を発する問題がある。   However, in the method of Japanese Patent Publication No. 56-19424, the center portion of the heat insulating material cannot be supported, and when a heat insulating material having a small bending rigidity is constructed, a gap is generated between the floor material and the heat insulating material. When the cold air enters the gap, the heat insulating performance is deteriorated. On the other hand, in Japanese Patent Application Laid-Open No. 2003-307028, since a support member is bridged between the members and supported, even if a heat insulating material having a small bending rigidity is applied, a gap does not occur between the floor material and the member dimensions. If the internal dimensions between members change due to differences in member spacing or the like, it cannot be handled. Moreover, in any case, since a metal fitting is installed on the upper part of the member, there is a problem in that the metal fitting and the flooring material rub against each other during walking.

本発明は、これらの問題点を同時に解決できるとともに、施工性及びコスト面に優れた断熱材支持部材およびその施工法を提供することを課題とする。   This invention makes it a subject to provide the heat insulating material supporting member excellent in workability and cost, and its construction method while being able to solve these problems simultaneously.

前記課題を達成するための本発明の内容は以下の通りである。

A heat insulating material support member.
(2) (1) retaining the heat insulating material supporting member according to adjust the length of the array direction in the bent or curved so by the heat insulating material supporting member of the plate, the heat insulating member supporting member to the inter-member of a building And then filling the insulating material between the members of the building.

本発明によれば、支持部材全長において厚さ方向への折り曲げ又は湾曲が容易で、かつ幅方向への曲げ剛性が高いことを特徴とする断熱材支持部材を用いるため以下の効果が期待できる。
（１）断熱材支持部材を折り曲げ又は湾曲することによって、容易に長さ調整が可能となり、様々な部材内法に対応できる。
（２）断熱材支持部材を任意の形状に折り曲げ又は湾曲することで、支持範囲を容易に変更できる。 According to the present invention, the following effects can be expected because the heat insulating material support member is used which is easy to bend or bend in the thickness direction and has high bending rigidity in the width direction over the entire length of the support member.
(1) By bending or bending the heat insulating material support member, it is possible to easily adjust the length, and to cope with various in-member methods.
(2) The support range can be easily changed by bending or bending the heat insulating material support member into an arbitrary shape.

図１〜図３に本発明による断熱材支持部材の実施例を示す。断熱材支持部材１は、平行に並んだ少なくとも２つ以上の板材２と、それら板材間を連結する複数のリブ３で形成される。図１に示す断熱材支持部材は、平行に並んだ板材が直交する複数のリブで連結されて断熱材支持部材を形成している。図２に示す断熱材支持部材は、平行に並んだ板材が波型のリブで連結されて断熱材支持部材を形成している。図３に示す断熱材支持部材は、平行に並んだ板材がトラス状のリブで連結され断熱材支持部材を形成している。いずれの場合も、板材２を平行に並べ、板材間を複数のリブで形成することによって、断熱材支持部材１に厚みを与えることが可能となり、断熱材の支持ができ、幅方向の曲げ剛性を確保できる。   1 to 3 show an embodiment of a heat insulating material support member according to the present invention. The heat insulating material support member 1 is formed of at least two or more plate members 2 arranged in parallel and a plurality of ribs 3 connecting the plate members. The heat insulating material support member shown in FIG. 1 is formed by connecting parallel plate members by a plurality of orthogonal ribs to form a heat insulating material support member. The heat insulating material support member shown in FIG. 2 is formed by connecting parallel plate members with corrugated ribs. In the heat insulating material supporting member shown in FIG. 3, plate members arranged in parallel are connected by a truss-shaped rib to form a heat insulating material supporting member. In any case, by arranging the plate members 2 in parallel and forming a plurality of ribs between the plate members, it is possible to give the heat insulating material support member 1 a thickness, support the heat insulating material, and bending rigidity in the width direction. Can be secured.

断熱材支持部材１はプラスチック・紙・金属あるいはこれらの複合材から形成すればよく、リブ３は厚さ方向へ折り曲げられる形状であれば形は選ばない。金属としては鉄、アルミ等が挙げられ、紙としてはダンボール等が挙げられ、プラスチックとしてはポリエチレン、ポリプロピレン等が上げられる。プラスチック製が押し出し成型により、一体で製造でき、製造しやすく、折り曲げが容易で、幅方向への曲げ剛性が高く好ましい。
次に本発明による断熱材の施工法を図４〜図８に基づき説明する。図４は、土台、大引き、胴差し、梁、桁、柱、間柱、根太、垂木、胴縁等の部材４間の内法に合わせて断熱材支持部材１をＺ型状に折り曲げ、部材４側面に釘、鋲、ピン、ねじ、ステープル等の固定金具５で留め付ける例である。断熱支持部材１は、支持部材全長において厚さ方向への折り曲げが容易なため、部材４間の内法がいかように変化しようとも、容易に長さ調整ができることとなる。 The heat insulating material support member 1 may be formed of plastic, paper, metal, or a composite material thereof, and the rib 3 may be formed in any shape as long as it is bent in the thickness direction. Examples of the metal include iron and aluminum, examples of the paper include cardboard, and examples of the plastic include polyethylene and polypropylene. Plastic is preferable because it can be manufactured integrally by extrusion, easy to manufacture, easy to bend, and has high bending rigidity in the width direction.
Next, the construction method of the heat insulating material by this invention is demonstrated based on FIGS. FIG. 4 shows a structure in which a heat insulating material support member 1 is bent into a Z shape in accordance with the inner method between members 4 such as a base, a large pull, a barrel, a beam, a girder, a pillar, a stud, a joist, a rafter, a trunk edge, etc. This is an example of fixing to the four side surfaces with fixing brackets 5 such as nails, scissors, pins, screws and staples. Since the heat insulating support member 1 can be easily bent in the thickness direction over the entire length of the support member, the length can be easily adjusted regardless of how the inner method between the members 4 changes.

図５は、断熱支持部材１をくの字状に折り曲げ、平行する部材４とこれと直交する部材４間に固定金具５で留め付ける例である。図６は、断熱材支持部材１をＷ状に折り曲げ、平行する部材４間に固定金具５で複数箇所留め付ける例である。図７は、断熱材支持部材１をU状に湾曲させ、平行する部材４間に固定金具５で複数箇所留め付ける例である。いずれの場合も、断熱支持部材１を任意の形状に折り曲げ又は湾曲させて容易に留め付けられ、支持範囲を容易に変更することができる。次いで図８に示すように断熱材６を断熱材支持部材１に支持させて、該建築物の部材４間に充填する。断熱材支持部材１に厚みがあり、幅方向の曲げ剛性があることから、十分断熱材の支持が可能となる。断熱材としては、グラスウール・ロックウール等の繊維系断熱材、ポリエチレン系、スチレン系、フェノール系、ウレタン系等の樹脂発泡体からなる板状発泡断熱材が好適に用いられる。   FIG. 5 shows an example in which the heat insulating support member 1 is bent in a U-shape and fastened with a fixing bracket 5 between the parallel member 4 and the member 4 orthogonal thereto. FIG. 6 shows an example in which the heat insulating material support member 1 is bent into a W shape and fixed at a plurality of positions with the fixing metal fittings 5 between the parallel members 4. FIG. 7 shows an example in which the heat insulating material support member 1 is bent in a U shape and is fastened at a plurality of positions with the fixing metal fittings 5 between the parallel members 4. In any case, the heat insulating support member 1 can be easily bent and bent into an arbitrary shape, and the support range can be easily changed. Next, as shown in FIG. 8, the heat insulating material 6 is supported by the heat insulating material supporting member 1 and filled between the members 4 of the building. Since the heat insulating material support member 1 is thick and has a bending rigidity in the width direction, the heat insulating material can be sufficiently supported. As the heat insulating material, fiber type heat insulating materials such as glass wool and rock wool, and plate-like foam heat insulating materials made of resin foams such as polyethylene, styrene, phenol and urethane are preferably used.
