〈支持部分〉
断熱材を支持するための支持部分は、断熱材を有効に支持することができるように、適切な幅、長さ及び厚さを有している板状体であることが好ましい。断熱材を施工する面を「内側」とする場合、固定部材の支持部分の位置は、断熱材の位置よりも、外側に位置することになる。
<Supporting part>
The support portion for supporting the heat insulating material is preferably a plate-like body having an appropriate width, length, and thickness so that the heat insulating material can be effectively supported. When the surface on which the heat insulating material is applied is “inside”, the position of the support portion of the fixing member is positioned outside the position of the heat insulating material.
例えば、支持部分の平均幅は、１０ｍｍ以上、２０ｍｍ以上、３０ｍｍ以上又は５０ｍｍ以上であってもよく、２００ｍｍ以下、１５０ｍｍ以下、１００ｍｍ以下又は８０ｍｍ以下であってもよい。また支持部分の平均長さ（垂直部分からその端部までの平均寸法）は、３０ｍｍ以上、５０ｍｍ以上、８０ｍｍ以上又は１００ｍｍ以上であってもよく、５００ｍｍ以下、４００ｍｍ以下、３００ｍｍ以下又は２００ｍｍ以下であってもよい。さらに、支持部分の平均厚さは、０．０５ｍｍ以上、０．１ｍｍ以上、０．２ｍｍ以上又は０．３ｍｍ以上であってもよく、３．０ｍｍ以下、２．０ｍｍ以下、１．０ｍｍ以下又は０．８ｍｍ以下であってもよい。 For example, the average width of the support portion may be 10 mm or more, 20 mm or more, 30 mm or more, or 50 mm or more, or 200 mm or less, 150 mm or less, 100 mm or less, or 80 mm or less. The average length of the support part (average dimension from the vertical part to the end thereof) may be 30 mm or more, 50 mm or more, 80 mm or more, or 100 mm or more, and is 500 mm or less, 400 mm or less, 300 mm or less, or 200 mm or less. There may be. Furthermore, the average thickness of the support part may be 0.05 mm or more, 0.1 mm or more, 0.2 mm or more, or 0.3 mm or more, 3.0 mm or less, 2.0 mm or less, 1.0 mm or less, or It may be 0.8 mm or less.
本発明の固定部材がＴ字形である場合、支持部分は垂直部分の中間位置から延びていることができる。ここで、中間位置とは、本発明の固定部材が、本発明の効果を与えることができる範囲の位置であれば、特に限定されない。例えば、本発明の固定部材がＴ字形である場合、支持部分は、垂直部分のちょうど中央から、垂直部分の全長の０％〜４５％、０％〜３０％又は０％〜１５％の寸法だけずれた位置で、延びていてもよい。 When the fixing member of the present invention is T-shaped, the support portion can extend from an intermediate position of the vertical portion. Here, the intermediate position is not particularly limited as long as the fixing member of the present invention is within a range where the effects of the present invention can be provided. For example, when the fixing member of the present invention is T-shaped, the support portion is a dimension of 0% to 45%, 0% to 30%, or 0% to 15% of the entire length of the vertical portion from the exact center of the vertical portion. It may extend at a shifted position.
本発明の固定部材がＬ字形である場合、支持部分は垂直部分の端部から延びる。 When the fixing member of the present invention is L-shaped, the support portion extends from the end of the vertical portion.
〈垂直部分〉
支持部分に対して略垂直な垂直部分は、構造部材に固定した際に、支持部分が断熱材を有効に支持することができるように、適切な幅、長さ及び厚さを有している板状体であることが好ましい。ここで、略垂直とは、本発明の固定部材が、本発明の効果を与えることができる範囲であれば、特にその角度は限定されない。例えば、支持部分と垂直部分とのなす角度は、７５°〜１０５°、８０°〜１００°又は８５°〜９５°の範囲である。
<Vertical part>
The vertical portion that is substantially perpendicular to the support portion has an appropriate width, length, and thickness so that the support portion can effectively support the insulation when secured to the structural member. A plate-like body is preferable. Here, the term “substantially vertical” means that the angle is not particularly limited as long as the fixing member of the present invention is within a range in which the effects of the present invention can be provided. For example, the angle formed by the support portion and the vertical portion is in the range of 75 ° to 105 °, 80 ° to 100 °, or 85 ° to 95 °.
例えば、垂直部分の平均幅は、１０ｍｍ以上、２０ｍｍ以上、３０ｍｍ以上又は５０ｍｍ以上であってもよく、２００ｍｍ以下、１５０ｍｍ以下、１００ｍｍ以下又は８０ｍｍ以下であってもよい。また垂直部分の平均長さ（垂直部分からその端部までの平均寸法）は、３０ｍｍ以上、５０ｍｍ以上、８０ｍｍ以上又は１００ｍｍ以上であってもよく、５００ｍｍ以下、４００ｍｍ以下、３００ｍｍ以下又は２００ｍｍ以下であってもよい。さらに、支持部分の平均厚さは、０．０５ｍｍ以上、０．１ｍｍ以上、０．２ｍｍ以上又は０．３ｍｍ以上であってもよく、３．０ｍｍ以下、２．０ｍｍ以下、１．０ｍｍ以下又は０．８ｍｍ以下であってもよい。 For example, the average width of the vertical portion may be 10 mm or more, 20 mm or more, 30 mm or more, or 50 mm or more, or 200 mm or less, 150 mm or less, 100 mm or less, or 80 mm or less. Further, the average length of the vertical part (average dimension from the vertical part to the end thereof) may be 30 mm or more, 50 mm or more, 80 mm or more, or 100 mm or more, and is 500 mm or less, 400 mm or less, 300 mm or less, or 200 mm or less. There may be. Furthermore, the average thickness of the support part may be 0.05 mm or more, 0.1 mm or more, 0.2 mm or more, or 0.3 mm or more, 3.0 mm or less, 2.0 mm or less, 1.0 mm or less, or It may be 0.8 mm or less.
〈垂直部分−突起〉
本発明の固定部材の垂直部分には、突起が存在している。突起は、構造部材に突き刺ささることができ、それにより固定部材の支持部分で断熱材を支持することができれば、特にその形状、大きさ、個数等は限定されない。
<Vertical part-protrusion>
There is a protrusion on the vertical portion of the fixing member of the present invention. The shape, size, number, and the like of the protrusions are not particularly limited as long as the protrusions can be pierced into the structural member and thereby the heat insulating material can be supported by the support portion of the fixing member.
本発明の固定部材は、突起を構造部材に突き刺すだけで固定することができるため、非常に取扱いが容易である。例えば、既存建築物の壁面、天井裏、床下等のいずれの場所に断熱材を施工する場合には作業スペースが非常に限られている場合があるが、そのような場合であっても、固定部材を直接金槌等で打ち付けるだけで、固定部材を構造部材に固定することができる。 Since the fixing member of the present invention can be fixed simply by piercing the structural member, the handling is very easy. For example, the work space may be very limited when installing insulation on any of the walls, ceilings, under floors, etc. of existing buildings. The fixing member can be fixed to the structural member simply by striking the member directly with a hammer or the like.
突起は、垂直部分の非支持側に位置し、かつ支持部分と反対方向に略平行に延びる突起であってもよい。本発明の断熱材固定部材の支持部分を水平にして使用する場合、例えば本発明の固定部材を床下に用いる場合には、このような突起の存在は特に有用である。すなわち、板状の支持部分に対して掛かる断熱材の荷重は、垂直部分から突出している支持部分と反対方向に略平行に延びる突起が構造部材に突き刺さる力のモーメントになる。したがってこの場合、断熱材の荷重は、固定部材が構造部材に固定し続けるための推進力となる。 The protrusion may be a protrusion that is located on the non-supporting side of the vertical portion and extends substantially parallel to the direction opposite to the supporting portion. When the support portion of the heat insulating material fixing member of the present invention is used horizontally, for example, when the fixing member of the present invention is used under the floor, the presence of such protrusions is particularly useful. That is, the load of the heat insulating material applied to the plate-like support portion becomes a moment of force that a protrusion extending substantially parallel to the opposite direction to the support portion protruding from the vertical portion pierces the structural member. Therefore, in this case, the load of the heat insulating material becomes a driving force for the fixing member to keep fixing to the structural member.
上記の突起に加えて又はそれに換えて、突起は、垂直部分の支持側の端部に位置し、かつ垂直部分から略平行に延びる突起であってもよい。ここで略平行とは、本発明の固定部材が、本発明の効果を与えることができる範囲であれば、特にその角度は限定されない。例えば、それらのなす角度は、−１５°〜１５°、−１０°〜１０°又は−５°〜５°の範囲である。また、断熱材を支持し、かつ／又は構造部材に固定部材を固定するために、他の突起が存在していてもよい。 In addition to or instead of the above-described protrusion, the protrusion may be a protrusion that is located at the end of the vertical portion on the support side and extends substantially parallel to the vertical portion. Here, the term “substantially parallel” means that the angle of the fixing member of the present invention is not particularly limited as long as the fixing member of the present invention can provide the effects of the present invention. For example, the angle formed by them is in the range of −15 ° to 15 °, −10 ° to 10 °, or −5 ° to 5 °. In addition, other protrusions may be present to support the heat insulating material and / or to fix the fixing member to the structural member.
突起の長さは、例えば１．０ｍｍ以上、２．０ｍｍ以上、３．０ｍｍ以上又は５．０ｍｍ以上であってもよく、５０ｍｍ以下、３０ｍｍ以下、２０ｍｍ以下又は１０ｍｍ以下であってもよい。突起の個数は、１個以上、２個以上、３個以上又は５個以上であってもよく、２０個以下、１５個以下又は１０個以下であってもよい。 The length of the protrusion may be, for example, 1.0 mm or more, 2.0 mm or more, 3.0 mm or more, or 5.0 mm or more, or 50 mm or less, 30 mm or less, 20 mm or less, or 10 mm or less. The number of protrusions may be 1 or more, 2 or more, 3 or more, or 5 or more, or 20 or less, 15 or less, or 10 or less.
〈垂直部分−開孔〉
本発明の固定部材の垂直部分には、釘、ビス等の固定手段を用いて、構造部材に固定部材をさらに固定するための開孔が存在していてもよい。開孔は、好ましくは断熱材の非支持側に位置する。構造部材が、突起が突き刺しにくい材料で構成されている場合には、このような開孔から固定手段を用いて固定部材を固定することは有用である。
<Vertical part-Opening>
In the vertical portion of the fixing member of the present invention, there may be an opening for further fixing the fixing member to the structural member using fixing means such as a nail or a screw. The aperture is preferably located on the non-supporting side of the insulation. When the structural member is made of a material in which the protrusion is difficult to pierce, it is useful to fix the fixing member using the fixing means from such an opening.
〈材料〉
本発明の固定部材の材料は、本発明の固定部材が本発明の効果を与えることができる範囲であれば、特に限定されない。例えば、本発明の固定部材を、有機系材料、無機系材料又はこれらの組合せから構成することができる。
<material>
The material of the fixing member of the present invention is not particularly limited as long as the fixing member of the present invention can provide the effects of the present invention. For example, the fixing member of the present invention can be composed of an organic material, an inorganic material, or a combination thereof.
有機系材料としては、プラスチック等、特に強化プラスチック等を挙げることができ、この場合には射出成形等で容易に適切な形状に成形することができるため有用である。 Examples of the organic material include plastics, particularly reinforced plastics. In this case, it is useful because it can be easily molded into an appropriate shape by injection molding or the like.
無機系材料としては、無機酸化物材料、金属材料等を挙げることができる。具体的には、無機酸化物としては、ガラス、セラミック等を挙げることができる。また、金属材料としては、鉄、アルミニウム、銅及びそれらの合金（例えば、ステンレス鋼等）を挙げることができる。 Examples of inorganic materials include inorganic oxide materials and metal materials. Specifically, examples of the inorganic oxide include glass and ceramic. Moreover, iron, aluminum, copper, and those alloys (for example, stainless steel etc.) can be mentioned as a metal material.
これらの中でも特に、本発明の固定部材は、１枚の金属材料から形成されていることが好ましい。この場合には、製造が容易というだけではなく、図３に示すように断熱材及び固定部材を複数用いる場合には、図２（ｃ）に示すように１つの固定部材を開いて、他の１つの固定部材の突起をそこに挿入することができる。 Among these, the fixing member of the present invention is preferably formed from a single metal material. In this case, not only the manufacture is easy, but when a plurality of heat insulating materials and fixing members are used as shown in FIG. 3, one fixing member is opened as shown in FIG. The protrusion of one fixing member can be inserted there.
〈断熱材〉
本発明の断熱材固定部材によって固定される断熱材は、発泡樹脂系断熱材等の有機系断熱材、ロックウール系断熱材、グラスウール系断熱材等の無機繊維系断熱材等の公知の断熱材をいずれも使用することができる。
<Insulation material>
The heat insulating material fixed by the heat insulating material fixing member of the present invention is a known heat insulating material such as an organic heat insulating material such as a foamed resin heat insulating material, an inorganic fiber heat insulating material such as a rock wool heat insulating material, or a glass wool heat insulating material. Any of these can be used.
この中でも特に、いわゆるボード状の無機繊維系断熱材は、床下に断熱材を施工する際の取扱い性が高いため有用である。すなわち、ボード状の無機繊維系断熱材は、それが施工される床下の構造部材間（例えば、大引間）の寸法より僅かに大きな寸法を有していることによって、強引に縮めて構造部材間に挿入して、一時的に固定することができる。断熱材を一時的に固定できている状態のうちに、本発明の固定部材の支持部分によって断熱材を支持させながら、構造部材に固定部材の突起を突き刺すことで、非常に容易に無機繊維系断熱材を固定することができる。 Among these, a so-called board-like inorganic fiber-based heat insulating material is particularly useful because it has a high handleability when a heat insulating material is installed under the floor. In other words, the board-like inorganic fiber-based heat insulating material has a size slightly larger than the size between the structural members under the floor on which it is constructed (for example, the large drawing space), thereby forcibly shrinking the structural member. It can be inserted in between and temporarily fixed. In the state in which the heat insulating material can be temporarily fixed, while supporting the heat insulating material by the support portion of the fixing member of the present invention, it is very easy to pierce the protrusion of the fixing member into the structural member, so that the inorganic fiber system Insulation can be fixed.
このようなボード状の無機繊維系断熱材としては、特にボード状のグラスウール系断熱材を挙げることができる。このようなボード状のグラスウール系断熱材の密度は、２０ｋｇ／ｍ３以上又は２５ｋｇ／ｍ３以上であってもよく、１００ｋｇ／ｍ３以下、８０ｋｇ／ｍ３以下、６０ｋｇ／ｍ３以下又は４０ｋｇ／ｍ３以下であってもよい。グラスウール系断熱材の密度を高くすると、断熱性が高くなる一方で、フェルト状からボード状になって変形しにくくなる。 Examples of such a board-like inorganic fiber-based heat insulating material include a board-shaped glass wool heat insulating material. The density of the board-like glass wool-based heat insulating material may be 20 kg / m 3 or more or 25 kg / m 3 or more, and is 100 kg / m 3 or less, 80 kg / m 3 or less, 60 kg / m 3 or less, or 40 kg. / M 3 or less. When the density of the glass wool-based heat insulating material is increased, the heat insulating property is increased, while the felt shape is changed to the board shape and is not easily deformed.
グラスウール系断熱材には、それがボード状となるように比較的高い含有量でバインダー樹脂が含まれていてもよい。バインダー樹脂としては、フェノール樹脂等を挙げることができ、バインダー樹脂は、グラスウール系断熱材の総重量に対して、３重量％以上、５重量％以上、又は７重量％以上、また２０重量％以下、１５重量％以下、又は１２重量％以下の範囲で、グラスウール系断熱材に含まれていてもよい。例えば、密度が２０ｋｇ／ｍ３以上１００ｋｇ／ｍ３以上であるグラスウール系断熱材の場合には、７重量％以上１２重量％以下の含有量でバインダー樹脂を有している場合に、ボード状の形状を維持しやすい。 The glass wool-based heat insulating material may contain a binder resin with a relatively high content so that it becomes a board shape. Examples of the binder resin include a phenol resin. The binder resin is 3% by weight or more, 5% by weight or more, or 7% by weight or more, and 20% by weight or less based on the total weight of the glass wool-based heat insulating material. 15% by weight or less, or 12% by weight or less, may be contained in the glass wool-based heat insulating material. For example, in the case of a glass wool-based heat insulating material having a density of 20 kg / m 3 or more and 100 kg / m 3 or more, when it has a binder resin with a content of 7 wt% or more and 12 wt% or less, Easy to maintain shape.
バインダー樹脂としては、フェノール樹脂、アクリル樹脂、エポキシ樹脂、メラミン樹脂等のグラスウール系断熱材用のバインダー樹脂を挙げることができる。また、ホルムアルデヒドを実質的に放出しない、天然由来の材料を主成分とするバインダーを用いてもよい。このようなバインダーとしては、特表２００９−５１７５１３号、特表２００９−５１７５１４号等に記載のバインダーを挙げることができる。 Examples of the binder resin include binder resins for glass wool-based heat insulating materials such as phenol resins, acrylic resins, epoxy resins, and melamine resins. Moreover, you may use the binder which has a natural origin material as a main component which does not discharge | release formaldehyde substantially. Examples of such binders include binders described in JP-T 2009-517513 and JP-T 2009-517514.
〈構造部材〉
本発明の断熱材固定部材が固定される構造部材としては、建築物の一部であれば特に限定されない。構造部材は、例えば、大引、根太、胴縁、間柱、柱、梁等であってもよい。この構造部材は、突起が突き刺しやすいように、木材等の材料で構成されていることが好ましい。
<Structural members>
The structural member to which the heat insulating material fixing member of the present invention is fixed is not particularly limited as long as it is a part of a building. The structural member may be, for example, a large drawing, joist, trunk edge, stud, pillar, beam or the like. This structural member is preferably made of a material such as wood so that the protrusion can be easily pierced.
《断熱構造体》
本発明の断熱構造体は、上記の断熱材固定部材と、それによって上記の構造部材に固定される上記の断熱材を含む。この断熱構造体は、建築物の壁面、床下、屋根裏等に断熱材を設置するために用いることができる。
《Insulation structure》
The heat insulating structure of the present invention includes the heat insulating material fixing member and the heat insulating material fixed thereby to the structural member. This heat insulating structure can be used for installing a heat insulating material on a wall surface, under the floor, attic, etc. of a building.
本発明の断熱構造体は、既存の壁面の内側面材、既存の床材等を破壊する必要なく、設置することができるため、既存の建築物に対して断熱材を設置する際に用いる場合に特に有用である。 Since the heat insulating structure of the present invention can be installed without the need to destroy the inner wall surface material of the existing wall surface, the existing flooring material, etc., when using the heat insulating material for an existing building Is particularly useful.
《断熱材の施工方法》
本発明の断熱材の施工方法は、上記の断熱材を、上記の固定部材を用いて、建築物の壁面、天井裏、床下等の場所に設置する方法に関する。この方法は、上記の断熱材を、施工する構造部材間に嵌め込む工程；及び上記の固定部材の垂直部分にある突起を構造部材に突き刺して固定部材を固定する工程を含む。
<Insulation method>
The construction method of the heat insulating material of this invention is related with the method of installing said heat insulating material in places, such as a wall surface of a building, a ceiling back, a floor, using said fixing member. The method includes a step of fitting the heat insulating material between the structural members to be constructed; and a step of piercing the structural member with a protrusion on a vertical portion of the fixing member to fix the fixing member.
上記の２つの工程は順不同であってもよいが、断熱材がボード状断熱材等である場合には、断熱材を構造部材間に嵌め込んだ後に、固定部材を固定する工程を行なってもよい。この場合には、固定部材の支持部分で断熱材を支持しながら、固定部材を固定する。 The above two steps may be in any order, but when the heat insulating material is a board-like heat insulating material or the like, the step of fixing the fixing member may be performed after the heat insulating material is fitted between the structural members. Good. In this case, the fixing member is fixed while the heat insulating material is supported by the supporting portion of the fixing member.
本発明の断熱材の施工方法は、上記の方法によって固定した断熱材の外側に、第２の断熱材を第２の固定部材を用いて固定する工程をさらに含んでもよい。この場合には、上記の工程において用いた第１の断熱材固定部材が、１枚の金属板で形成されていることによって、第２の固定部材の突起を、第１の固定部材の支持部分と垂直部分の間に挿入することによって、第１の断熱材固定部材と第２の断熱材固定部材とを重ねて使用することができる。第２の断熱材固定部材としては、上記の断熱材固定部材の他に、従来から公知の固定部材を用いてもよい。 The construction method of the heat insulating material of the present invention may further include a step of fixing the second heat insulating material using the second fixing member outside the heat insulating material fixed by the above method. In this case, the first heat insulating material fixing member used in the above process is formed of a single metal plate, so that the protrusion of the second fixing member is supported by the supporting portion of the first fixing member. By inserting it between the vertical portions, the first heat insulating material fixing member and the second heat insulating material fixing member can be used in an overlapping manner. As a 2nd heat insulating material fixing member, you may use a conventionally well-known fixing member other than said heat insulating material fixing member.
この断熱材の施工方法では、上記の固定部材を用いるために、作業スペースが非常に限られている場所であっても容易に実施することができる。例えば、固定部材を構造部材に固定する際には、固定部材を直接金槌等で打ち付けることができるため、非常に容易に実施することができる。 In this heat insulating material construction method, since the above-described fixing member is used, it can be easily implemented even in a place where the work space is very limited. For example, when fixing the fixing member to the structural member, the fixing member can be directly struck with a hammer or the like, so that it can be carried out very easily.
