Description
【０００１】[0001]
本考案は、建築物の屋根、壁、床等の支持部材間に嵌め込むための部材間挿入 断熱材に関する。 The present invention relates to an inter-member insertion heat insulating material for fitting between supporting members such as a roof, a wall and a floor of a building.
【０００２】[0002]
最近の建築物においては、変化の激しい自然環境から住居環境を守るために、 或いは冷暖房効率を高めるために、建築物の外周に発泡プラスチックからなる断 熱材を取り付けて建築物の周囲を包囲し、建築物全体の高断熱化、高気密化を図 ることが広く行われている。そして、施工の際の便宜等を図るため、断熱材を矩 形平板状にパネル化し、このパネル化した断熱材を一対の支持部材間に嵌挿して 配置するようにしたものとして部材間挿入断熱材がある。 In recent buildings, in order to protect the living environment from the rapidly changing natural environment, or to improve the heating and cooling efficiency, a heat insulating material made of foam plastic is attached to the periphery of the building to surround it. In addition, it is widely practiced to improve the heat insulation and airtightness of the entire building. For convenience of construction, the heat insulating material is panelized into a rectangular flat plate, and the panelized heat insulating material is inserted and arranged between a pair of support members. There is wood.
【０００３】 この種の部材挿入断熱材としては、支持部材間の所定寸法の開口への嵌め込み を容易となすため、矩形平板状の断熱材の表裏両面に長さ方向に沿って平行に延 びる多数のスリットを設け、このスリットによって幅方向にある程度の伸縮性を 持たせたものが知られている（例えば実公昭６１−４５０９６号公報参照）。As this type of member insertion heat insulating material, in order to facilitate fitting into openings of a predetermined size between support members, it extends parallel to the front and back surfaces of a rectangular flat plate heat insulating material along the length direction. It is known that a large number of slits are provided and the slits have some elasticity in the width direction (see, for example, Japanese Utility Model Publication No. 61-45096).
【０００４】 また、出願人は、先に実願昭５９−７１９０９号（実開昭６０−１８４９０３ 号）として、図３に示すようなものを提案した。 すなわち、根太や間柱等の支持部材２，２間に挿入した時に圧縮を受ける矩形 平板状の断熱材１の両側縁部、例えば、断熱材１の全幅をＷ3 とした時、各側端 面からこの全幅Ｗ3 の約１／４の領域Ｗ4 （＝Ｗ3 ／４）内に、長さ方向に沿っ て平行に延びる複数のスリット１ａ，１ａ…を表裏両面から互い違いに設け、こ れによって、支持部材２，２からの圧縮力が最も効果的に断熱材１の両側縁部に 加わるようにして、効率良く収縮させ、スリットを設けない中央付近の変形によ る垂れ下がりや凹凸等が生じないようにしたものである。In addition, the applicant has previously proposed, as Japanese Utility Model Application No. 59-71909 (Japanese Utility Model Application No. 60-184903), the one shown in FIG. That is, both side edges of the heat insulating material 1 in the shape of a rectangular flat plate that receives compression when inserted between the supporting members 2 and 2 such as joists and studs, for example, when the entire width of the heat insulating material 1 is W 3 , the approximately 1/4 of the region W 4 of the full width W 3 in (= W 3/4) in, alternately a plurality of slits 1a extending in parallel along the longitudinal direction, the 1a ... from both sides, is this from By this, the compressive force from the support members 2 and 2 is most effectively applied to both side edges of the heat insulating material 1 so that the heat insulating material 1 can be efficiently shrunk, and sagging or unevenness due to deformation near the center where no slit is provided. It was designed so that it would not occur.

しかしながら、上記従来例においては、特にこれを屋根用の断熱材として垂木 間に配置しようとすると、この断熱材は、その両側端面において垂木と接触し、 この接触によって発生する摩擦力のみで保持されているため、自重や寸法公差、 更には、設置後の木材の乾燥による収縮や発泡プラスチックのばね作用力の低下 等により垂木（支持部材）間からずれ落ちて落下してしまうことがあるばかりで なく、断熱材の厚さを厚くしようとすると、この厚さに合わせて垂木の高さも高 くしなくてはならないといった問題点があった。 However, in the above-mentioned conventional example, particularly when it is attempted to arrange it between the rafters as a heat insulating material for the roof, this heat insulating material comes into contact with the rafters at both end faces thereof and is retained only by the frictional force generated by this contact. Therefore, the weight of the rafter (supporting member) may be dropped and dropped due to its own weight, dimensional tolerance, shrinkage due to drying of wood after installation, reduction of spring action force of foamed plastic, etc. However, when trying to increase the thickness of the heat insulating material, there was a problem in that the height of the rafters must be increased according to this thickness.
【０００６】 本考案は上記に鑑み、支持部材間に密着させた状態で容易に嵌挿させて配置す ることができ、しかも屋根用の断熱材として使用しても、自重や寸法公差等によ って垂木間から落下してしまうことがないばかりでなく、断熱材の厚さを厚くし ても、垂木の高さを高くすることなく保持できるようにしたものを提供すること を目的とする。In view of the above, the present invention can be easily inserted and arranged in a state in which the support members are in close contact with each other, and even when used as a heat insulating material for a roof, the weight and dimensional tolerances are small. Therefore, not only does it fall from the space between rafters, but it also aims to provide a product that can be held without increasing the height of the rafters, even if the heat insulating material is thickened. To do.

上記目的を達成するため、本考案に係る部材間挿入断熱材は、矩形平板状の発 泡プラスチックからなり、両側縁部に長さ方向全長に亘って直線状に延び同一の 方向に開口する横断面鉤形の切欠き部を形成するとともに、この切欠き部の近傍 の、例えば各側端面から全幅の１／４の領域内に該切欠き部と平行に延び板面に 対して略垂直で切込み深さが板厚の半分以上の複数のスリットを表裏両面から互 い違いに形成したことを特徴とするものである。 In order to achieve the above object, the inter-member insertion heat insulating material according to the present invention is made of a rectangular flat plate foamed plastic, and extends in the same direction in a straight shape at both side edges along the entire length in the longitudinal direction. A hook-and-loop notch is formed, and in the vicinity of this notch, for example, extending parallel to the notch in a region of 1/4 of the total width from each side end face, and substantially perpendicular to the plate surface. The feature is that a plurality of slits having a cut depth of more than half of the plate thickness are formed alternately on the front and back surfaces.

上記のように構成した本考案によれば、これを例えば屋根の断熱材として使用 する場合、軒先から棟に向かって延びる垂木間にこの断熱材を上方から嵌挿させ つつ配置するのであるが、この時、両側縁部に形成した切欠き部内に垂木が位置 するようになし、かつ両垂木間で断熱材の両切欠き部で挟まれた部分を圧縮させ て挟持することにより、垂木に密着させた状態でこの内部に嵌挿させる。すると 、断熱材の両側縁部に設けたスリットが圧縮力に応じて収縮することによって、 この作業を容易に行うことができ、しかも垂木の上部に断熱材の両側縁部が位置 してこの落下を確実に防止し、かつ断熱材の肉厚と垂木の高さとを等しくする必 要をなくして、厚い肉厚の断熱材であっても、低い高さの垂木で確実に保持する ことができる。 According to the present invention configured as described above, when this is used as a heat insulating material for a roof, for example, the heat insulating material is arranged while being inserted from above between the rafters extending from the eaves toward the ridge. At this time, the rafters are arranged so as to be located in the notches formed on both side edges, and the part sandwiched between the notches of the heat insulating material is compressed between the two rafters so that the rafters come into close contact with the rafters. It is inserted in this inside in the state. Then, the slits provided on both side edges of the heat insulating material contract according to the compressive force, and this work can be easily performed. Can be reliably prevented, and the thickness of the heat insulating material and the height of the rafters do not have to be equalized, so even if the heat insulating material is thick, the rafters with a low height can reliably hold it. .

The heat insulating material 10 is made of expanded plastic such as expanded polystyrene or expanded polyurethane and is formed into a rectangular flat plate shape.
【００１０】 この断熱材１０の裏面側の両側縁部には、長さ方向全長に亘って直線状に延び る横断面鉤型の切欠き部１０ａ，１０ａが設けられている。更に、この各切欠き 部１０ａの近傍には、この切欠き部１０ａと平行に、即ち断熱材１０の長さ方向 全長に亘って直線状に延び板面に対して略垂直な複数のスリット１０ｂ，１０ｂ …が表裏両面から互い違いに設けられている。Notched portions 10 a, 10 a having a hook-shaped cross section extending linearly over the entire length in the length direction are provided on both side edges on the back surface side of the heat insulating material 10. Further, in the vicinity of each cutout portion 10a, a plurality of slits 10b extending in parallel with the cutout portion 10a, that is, linearly extending over the entire length in the length direction of the heat insulating material 10 and substantially perpendicular to the plate surface. , 10b are provided alternately from the front and back sides.
【００１１】 ここに、前記各スリット１０ｂは、断熱材１０の全幅をＷ1 とした時、各側端 面から該全幅Ｗ1 の１／４の領域Ｗ2 （＝Ｗ1 ／４）内に形成されている。また 、各スリット１０ｂの表面又は裏面からの切込み深さｔは、断熱材１０の肉厚Ｔ の半分以上（ｔ＞Ｔ／２）に設定されているが、約２／３倍（ｔ＝Ｔ・２／３） 程度が望ましい。[0011] Here, each of the slits 10b is the full width of the heat insulating material 10 when the W 1, within 1/4 of the region W 2 of該全width W 1 from the side end face (= W 1/4) Has been formed. Further, the depth of cut t from the front surface or the back surface of each slit 10b is set to be at least half the thickness T 1 of the heat insulating material 10 (t> T / 2), but about 2/3 times (t = T).・ About 2/3) is desirable.
【００１２】 更に、前記各スリット１０ｂの幅は、断熱材１０の大きさにも依るが、０．０ ５〜５ｍｍ、特に０．１〜３ｍｍ、更に好ましくは、０．２〜２ｍｍ程度の大き さである。Further, the width of each slit 10b depends on the size of the heat insulating material 10, but is 0.05 to 5 mm, particularly 0.1 to 3 mm, and more preferably 0.2 to 2 mm. That's it.
【００１３】 そして、前記断熱材１０を支持部材（図示せず）間に挿入する際には、この断 熱材１０の両側縁部に形成した切欠き部１０ａ，１０ａ内に支持部材の隅部が位 置するようになし、かつ両支持部材間で断熱材１０の両切欠き部１０ａ，１０ａ で挟まれた部分Ｌ1 を圧縮させて挟持することにより、断熱材１０を支持部材に 密着させた状態でこの内部に嵌挿させるのであり、この時、断熱材１０の両側縁 部に設けた各スリット１０ｂが圧縮力に応じて収縮することによって、この作業 を容易に行うことができる。When the heat insulating material 10 is inserted between the support members (not shown), the corners of the support member are provided in the cutouts 10 a, 10 a formed on both side edges of the heat insulating material 10. Are arranged so that the heat insulating material 10 is adhered to the supporting member by compressing and sandwiching the portion L 1 sandwiched between the notch portions 10a, 10a of the heat insulating material 10 between the both supporting members. The slits 10b provided on both side edges of the heat insulating material 10 contract at this time in response to the compressive force, so that this work can be easily performed.
【００１４】 しかも、この時の圧縮力が最も効果的に断熱材１０の両側縁部に加わるように して、効率良く収縮させ、スリットを設けない中央付近の変形による垂れ下がり や凹凸等が生じないようにすることができる。Moreover, the compressive force at this time is most effectively applied to both side edges of the heat insulating material 10 so that the heat insulating material 10 is efficiently shrunk, and sagging or unevenness due to deformation near the center where no slit is provided does not occur. You can
【００１５】 図２は、前記実施例を屋根用の断熱材として使用した時の使用例を示すもので 、軒先から棟に向かって複数の垂木１１，１１…が平行に配置されている。この 各垂木１１，１１間の間隔Ｌ2 は、断熱材１０の両切欠き部１０ａ，１０ａで挟 まれた部分Ｌ1 の長さより、例えば５ｍｍ程度短く設定されている。FIG. 2 shows a usage example when the above-mentioned embodiment is used as a heat insulating material for a roof, and a plurality of rafters 11, 11 ... Are arranged in parallel from the eaves toward the ridge. The interval L 2 between the rafters 11, 11 is set to be, for example, about 5 mm shorter than the length of the portion L 1 sandwiched between the notches 10a, 10a of the heat insulating material 10.
【００１６】 そして、この各垂木１１，１１間に各断熱材１０を上方から嵌挿させつつ配置 するのであるが、この時、断熱材１０の両側縁部に形成した切欠き部１０ａ，１ ０ａ内に垂木１１，１１が位置するようになし、かつ両垂木１１，１１間で断熱 材１０の両切欠き部１０ａ，１０ａで挟まれた部分Ｌ1 を圧縮させて挟持するこ とにより、この各切欠き部１０ａを各垂木１１の外面に密着させ、この状態で垂 木１１，１１の内部に嵌挿させる。Then, the heat insulating material 10 is arranged while being inserted from above between the rafters 11 and 11. At this time, the cutout portions 10a and 10a formed on both side edges of the heat insulating material 10 are arranged. By arranging the rafters 11 and 11 so as to be located inside and compressing and sandwiching the portion L 1 sandwiched between the notches 10a and 10a of the heat insulating material 10 between the two rafters 11 and 11, Each notch portion 10a is brought into close contact with the outer surface of each rafter 11, and in this state, it is fitted inside the rafters 11, 11.

Ventilation layers 14, 14, ... Are formed between the 10, 10 ,. As a result, cold air or the like can be passed through the ventilation layers 14, 14 in the summer and warm air or the like in the winter.
【００１９】 前記各野地板１３は、例えば各垂木１１に向けて釘（図示せず）を打ちつける ことによって固定されている。 なお、本実施例は、上記使用例に限定されることなく、例えば根太等の支持部 材の間に断熱材を設け、この上に床下地材や床板を貼った床構造、更には壁構造 にも使用できることは勿論である。The field boards 13 are fixed by hitting nails (not shown) toward the rafters 11, for example. In addition, the present embodiment is not limited to the above-described use example, and for example, a floor structure in which a heat insulating material is provided between supporting members such as joists, and a floor base material or a floor board is attached thereon, and further a wall structure. Of course, it can also be used.
