Description

本発明は、下層屋根と上層屋根とからなる二層タイプの屋根において、その馳締タイプの下層屋根の馳締部に簡易且つ迅速に装着して、上層屋根を支持すると共に熱伸縮による板鳴り現象を防止する機能を有する建築用断熱支持具及びその支持具を備えた二層屋根に関する。 According to the present invention, in a two-layer type roof composed of a lower roof and an upper roof, the roof can be easily and quickly attached to the tightening portion of the lower roof of the tightening type to support the upper roof and squeal due to thermal expansion and contraction. The present invention relates to a building heat insulating support having a function of preventing a phenomenon and a two-story roof equipped with the support.

従来、下層屋根と上層屋根とからなる二層タイプの屋根又は壁等の外囲体が多く存在している。これらの外囲体は、新設の二層タイプの屋根(又は壁)及び既設の屋根(壁も含む)に新たに屋根(壁も含む)を新設した改修屋根が存在する。その下層屋根(又は壁)は、金属製の折板建築用板によって施工されている。 Conventionally, there are many surrounding bodies such as a two-layer type roof or a wall composed of a lower roof and an upper roof. As for these enclosures, there are a new two-story type roof (or wall) and a renovated roof in which a new roof (including a wall) is newly installed on an existing roof (including a wall). The lower roof (or wall) is constructed with metal folded-plate building boards.

この種の外囲体において、下馳部と上馳部とを有する折板屋根板材から構成され、その隣接する折板屋根板材同士の下馳部と上馳部とが馳締されて、折板屋根板材同士が連結されて折板屋根等が施工されるものが存在する。上層屋根と下層屋根との間には支持具が設けられており、該支持具は下層屋根上に装着され、前記支持具によって上層屋根が下層屋根上に支持されるものである。 In this kind of enclosure, it is composed of a folded plate roof plate material having a lower plate portion and an upper plate portion, and the lower plate portion and the upper plate portion of the adjacent folded plate roof plate materials are fastened and folded. Plate roof There are some that connect plate materials to each other to construct a folded plate roof or the like. A support is provided between the upper roof and the lower roof, and the support is mounted on the lower roof, and the upper roof is supported on the lower roof by the support.

そして、二層タイプの屋根では、上層及び下層の屋根において、外気温による温度差が生じ、この温度差により、上下の屋根を構成する折板屋根板材の熱伸縮に差が生じることがある。ここで、上下の屋根を支持する建築用断熱支持具には下層の屋根と上層の屋根との熱伸縮の差により、建築用断熱支持具と下層屋根との間にズレが生じ、そのときに、こすれ合い、騒音が生じる。一般的にこの騒音は板鳴と称せられている。 In the two-layer type roof, a temperature difference occurs due to the outside air temperature between the upper and lower roofs, and this temperature difference may cause a difference in thermal expansion and contraction of the folded plate roof plate materials constituting the upper and lower roofs. Here, the building insulation support that supports the upper and lower roofs is displaced between the building insulation support and the lower roof due to the difference in thermal expansion and contraction between the lower roof and the upper roof, and at that time. , Rubbing, noise is generated. This noise is generally called board noise.

このような、板鳴りを低減するための具体的な一例として特許文献1が挙げられる。特許文献1では、上方に位置し、上層の折板屋根の馳締部に装着される吊子を有する屋根板支持部材(71)と、下葺折板屋根上に設置される固定部材(8)とから構成されている。そし
て、屋根板支持部材(71)と、固定部材(8)とは相対的に摺動する構成となっている。
Patent Document 1 is given as a specific example for reducing such board noise. In Patent Document 1, a roof plate support member (71) having a hanger, which is located above and is attached to the fastening portion of the upper folded plate roof, and a fixing member (8) installed on the lower folded plate roof. ) And. The roof plate support member (71) and the fixing member (8) are relatively slidable.

特許文献1では、上記の構成とするために、レール部材(11)及び摺動部材(12)等が構成部材として加わっており、構造が複雑となり、部品点数が多くなり、そのために製造も面倒で、そのため高価なものとなる。また、接触面同士には潤滑剤が使用され、屋根の施工でも面倒且つ高価なものとなるおそれがある。 In Patent Document 1, rail members (11), sliding members (12), and the like are added as constituent members in order to have the above configuration, which complicates the structure and increases the number of parts, which makes manufacturing troublesome. Therefore, it becomes expensive. In addition, a lubricant is used between the contact surfaces, which may be troublesome and expensive even in roof construction.

また特許文献2では、二層屋根において支持具(C)と下部外囲体(B)との間に非金属性軟質帯材(5)を設けた実施形態が存在する。これによって、支持具(C)と下部外囲体(B)との
間に生ずるズレでは、非金属性軟質帯材(5)が設けられたことにより板鳴りを低減するも
のである。しかし、ここで、非金属性軟質帯材(5)は、支持具(C)を下部外囲体(B)上に設
置する前に、非金属性軟質帯材(5)を下部外囲体(B)上に予め貼着してゆかなければならない。
Further, in Patent Document 2, there is an embodiment in which a non-metallic soft band member (5) is provided between a support (C) and a lower outer enclosure (B) in a two-story roof. As a result, in the deviation that occurs between the support (C) and the lower outer body (B), the non-metallic soft band material (5) is provided to reduce the board noise. However, here, the non-metallic soft strip (5) puts the non-metallic soft strip (5) on the lower enclosure (B) before the support (C) is placed on the lower enclosure (B). (B) It must be pasted on top in advance.

このように、板鳴りを低減する工法においては、所定位置に間配りされた非金属性軟質帯材等のシートを、下層屋根の所定の位置に貼り付けなければならなかった。この場合、シートの配り忘れや数量不足により、貼着されていない箇所が発生し、求められる施工品質が得られなくなるおそれがあった。 As described above, in the construction method for reducing the board noise, a sheet such as a non-metallic soft strip material distributed at a predetermined position must be attached to a predetermined position on the lower roof. In this case, there is a risk that the required construction quality cannot be obtained because some parts are not attached due to forgetting to distribute the sheets or insufficient quantity.

また、特許文献1及び特許文献2等の従来技術において、支持具は、下層屋根に設置して、すぐに固定するものでなく、所定のおおよその場所に仮設置し、最終的に正確な設置位置を調整し、しかる後固定し、上層屋根を施工するものである。支持具の仮置きでは、馳締部を跨ぐようにして配置するが通常は下層屋根の馳締を左右の金具にて挟持するようにして固定するため、両金具は適正に離間していることが必要であった。支持具を下層屋根の馳締部にセットする場合は、両手で左右一対の両金具をそれぞれ手で持ちつつ、両金具を開き、その状態で馳締部に載せなければならなかった。やはり、この作業も面倒なものである。 Further, in the prior art such as Patent Document 1 and Patent Document 2, the support is not installed on the lower roof and fixed immediately, but is temporarily installed at a predetermined approximate place, and finally accurately installed. The position is adjusted, then fixed, and the upper roof is constructed. In the temporary placement of the support, the support is placed so as to straddle the fastening part, but normally the fastening of the lower roof is fixed by sandwiching it between the left and right metal fittings, so the two metal fittings must be properly separated. Was needed. When setting the support on the tightening part of the lower roof, it was necessary to open both metal fittings while holding the pair of left and right metal fittings with both hands, and place them on the tightening part in that state. After all, this work is also troublesome.

そこで、本発明の目的(解決しようとする技術的課題)は、極めて簡単な構成にて、二層タイプの屋根における板鳴りを低減し、且つその構成を極めて簡単にする二層屋根における建築用断熱支持具を提供することにある。 Therefore, an object of the present invention (a technical problem to be solved) is for construction in a two-story roof, which reduces board noise in a two-story roof with an extremely simple configuration and makes the configuration extremely simple. The purpose is to provide insulation supports.

そこで、発明者は上記課題を解決すべく、鋭意,研究を重ねた結果、請求項1の発明を、連結包持部を有し且つ該連結包持部の下端に台座部を有する第1挟持部材と、該第1挟持部材と同様に連結包持部を有し且つ該連結包持部の下端に台座部を有する第2挟持部材と、前記第1挟持部材と前記第2挟持部材とを左右対称にして接合する締付具と、前記第1挟持部材と前記第2挟持部材とを近接及び離間可能となるように連結固着される可撓性を有するシート材とを備え、前記第1挟持部材と前記第2挟持部材とが近接状態で前記シート材は幅方向中間箇所を上方側で折返し部が形成されてなる建築用断熱支持具としたことにより、上記課題を解決した。 Therefore, as a result of diligent research to solve the above problems, the inventor has obtained the invention of claim 1 in the first sandwich having a connecting holding portion and a pedestal portion at the lower end of the connecting holding portion.

The fastening portion of the lower roof is surrounded by the sheet material, is surrounded by both the first holding member and the second holding member, and is fixed by the fastener. The above problem was solved by forming a two-story roof in which the upper roof is supported on the upper side of the heat insulating support for construction.

請求項7の発明を、請求項6において、前記上層屋根の前記馳締部を支持する吊子は、樹脂被覆されてなる二層屋根としたことにより、上記課題を解決した。請求項8の発明を、請求項6又は7において、前記上層屋根の前記馳締部を構成する前記下馳締部と前記上馳部との間に樹脂の軟質帯材が貼着されてなる二層屋根としたことにより、上記課題を解決した。 According to the sixth aspect of the invention of claim 7, the above-mentioned problem is solved by forming the hanging member for supporting the fastening portion of the upper roof with a resin-coated two-layer roof. According to a sixth or seventh aspect of the present invention of claim 8, a soft band material of resin is attached between the lower fastening portion and the upper fastening portion constituting the fastening portion of the upper roof. The above problem was solved by using a two-story roof.

請求項1の発明では、建築用断熱支持具を下層屋根の馳締部上の所定位置に配置するときに、そのまま馳締部に支持具と共にシート材を載せることができるため、本発明の建築用断熱支持具の仮設置及び位置の微調整による最終設置を効率的に行うことができる。シート材は、支持具に貼着しており作業の省力化を実現できる。 In the invention of claim 1, when the heat insulating support for construction is arranged at a predetermined position on the fastening portion of the lower roof, the sheet material can be directly placed on the fastening portion together with the support, and thus the building of the present invention. It is possible to efficiently perform the temporary installation of the heat insulating support for use and the final installation by finely adjusting the position. The sheet material is attached to the support, which can save labor.

シート材は、支持具と下層屋根及びその馳締部も含めて非接触にすることができるので下層屋根への傷の発生を防止することができる。そして、シート材は、支持具と上層屋根と下層屋根との間との熱伸縮によるズレから生じる板鳴りを低減することが可能となる。また、二層屋根に本発明の建築用断熱支持具を使用したときに、第1挟持部材と第2挟持部材にはこれらを連結するようにしてシート材を装着しているので、該シート部材が下層屋根と上層屋根との間の熱伝達を遮断し、断熱の効果を発揮することができる。 Since the sheet material can be made non-contact with the support including the lower roof and its fastening portion, it is possible to prevent the lower roof from being scratched. Then, the sheet material can reduce the board noise caused by the displacement due to the thermal expansion and contraction between the support and the upper roof and the lower roof. Further, when the architectural heat insulating support of the present invention is used for the two-story roof, the sheet material is attached to the first sandwiching member and the second sandwiching member so as to connect them. Can block the heat transfer between the lower roof and the upper roof and exert the effect of heat insulation.

さらに、従来では、シート材と支持具とが完全に別体となっているため、シート材と支持具との数が合わず、施工ミスが発生したり、入荷時期が遅れたりした場合に工程が延期されることがあるが、本願発明では支持具とシート材は一体化されているので、何れの部材における配り忘れも防止できる。 Furthermore, in the past, since the sheet material and the support tool are completely separate, the process is performed when the number of the sheet material and the support tool does not match, a construction error occurs, or the arrival time is delayed. However, in the present invention, since the support and the sheet material are integrated, it is possible to prevent forgetting to distribute any member.

請求項2の発明では、シート材は馳締部と共に第1挟持部材と第2挟持部材のそれぞれの包持部に挿入可能な構成としたことにより、折板屋根板材同士の馳締部を良好な状態で包持することができる。請求項3の発明では、シート材は、方形状で且つ前記台座部との接着箇所は粘着性の接着面が設けられた構成により、第1挟持部材及び第2挟持部材のそれぞれの台座部とシート材との位置関係を単純にすることができ、したがって、第1挟持部材と第2挟持部材に対するシート材の貼着作業を簡単且つ効率的にできる。 In the invention of claim 2, the sheet material is configured to be insertable into the holding portions of the first holding member and the second holding member together with the fastening portion, so that the fastening portion between the folded plate roof plate materials is good. Can be carried in a state of being. In the invention of claim 3, the sheet material has a rectangular shape, and the adhesive portion with the pedestal portion is provided with an adhesive adhesive surface, so that the sheet material has a pedestal portion of each of the first sandwiching member and the second sandwiching member. The positional relationship with the sheet material can be simplified, and therefore, the work of attaching the sheet material to the first sandwiching member and the second sandwiching member can be easily and efficiently performed.

請求項4の発明では、シート材の前記接着面には離型シートが貼着され、該離型シートの剥離状態で前記第1挟持部材と前記第2挟持部材のそれぞれの台座部に接着自在としたことにより、第1挟持部材と第2挟持部材へのシート材の貼着作業をより一層効率的にできる。さらに、第1挟持部材と第2挟持部材と、シート材とはそれぞれ別々に保管しておき、現場にて屋根の施工等に際してこれらを使用するときに、第1挟持部材と第2挟持部材とにシート材を貼着することができ、これらを使用するまでの保管を良好な状態に保持できるものである。 In the invention of claim 4, a release sheet is attached to the adhesive surface of the sheet material, and the release sheet can be freely adhered to the respective pedestals of the first holding member and the second holding member in a peeled state. As a result, the work of attaching the sheet material to the first holding member and the second holding member can be made more efficient. Further, the first sandwiching member, the second sandwiching member, and the sheet material are stored separately, and when they are used for roof construction or the like at the site, the first sandwiching member and the second sandwiching member are used. Sheet materials can be attached to the roof, and storage until they are used can be maintained in good condition.

請求項5の発明では、シート材は、常時は平坦面となるように弾性力を有すると共に第1挟持部材と第2挟持部材とを離間させるように付勢する構成としたことにより、本発明の建築用断熱支持具をシート材が常時平坦状となる弾性力によって、締付具を緩めた状態で第1挟持部材と第2挟持部材とが所定間隔に開いた状態つまり離間した状態にできる。 In the invention of claim 5, the sheet material has an elastic force so as to be a flat surface at all times, and the first sandwiching member and the second sandwiching member are urged to be separated from each other. By the elastic force that the sheet material is always flat, the first holding member and the second holding member can be opened at a predetermined interval, that is, separated from each other in the state where the fastener is loosened. ..

したがって、本発明の建築用断熱支持具を折板屋根の馳締部上に設置するときに、第1挟持部材と第2挟持部材とが開き(離間)状態であるために、馳締部箇所に単に配置するのみで、シート材が馳締部を包持しつつ両連結包持部に馳締部が収まるようにセットすることが略即座にできる。これによって、建築用断熱支持具の仮設置及びその仮設置から、より正確な位置に微調整して締付具により締め付ける一連の作業を効率的に行うことができる。 Therefore, when the heat insulating support for building of the present invention is installed on the fastening portion of the folded plate roof, the first sandwiching member and the second sandwiching member are in an open (separated) state, so that the fastening portion is located. It is possible to set the sheet material so that the fastening portion fits in both connecting holding portions while holding the fastening portion by simply arranging the sheet material in. As a result, it is possible to efficiently perform a series of operations from the temporary installation of the heat insulating support for construction and the temporary installation thereof to fine adjustment to a more accurate position and tightening with the fastener.

請求項6の発明では、二層屋根における下層屋根及び上層屋根のそれぞれの折板屋根板材を馳締連結タイプとしたものである。そして、建築用断熱支持具を下層屋根の馳締部箇所に設置することで、シート材が馳締部箇所を包持すると共に第1挟持部材と第2挟持部材のそれぞれの連結包持部がシート材ごと馳締部を包持することができる。 In the invention of claim 6, the folded plate roof plate material of each of the lower roof and the upper roof in the two-story roof is a tightening connection type. Then, by installing the heat insulating support for construction at the tightening part of the lower roof, the sheet material holds the tightening part and the connecting holding parts of the first holding member and the second holding member are respectively. It is possible to hold the tightening part together with the sheet material.

これによって、建築用断熱支持具の締付具を締め付けるのみで、下層屋根上に設置することができ、且つシート材によって、下層屋根と建築用断熱支持具との金属材同士の接触が防がれて板鳴現象を防止することができる。また、シート材によって、下層屋根と上層屋根との間の熱伝達を遮断し、保温性を保つことができ省エンルギに寄与できる。請求項7の発明では、より一層断熱性が保たれる。請求項8の発明では、より一層板鳴現象を防止することができる。 As a result, it can be installed on the lower roof simply by tightening the fastener of the building insulation support, and the sheet material prevents the metal materials from coming into contact with each other between the lower roof and the building insulation support. It is possible to prevent the plate ringing phenomenon. In addition, the sheet material can block heat transfer between the lower roof and the upper roof, maintain heat retention, and contribute to energy saving. In the invention of claim 7, the heat insulating property is further maintained. According to the invention of claim 8, the plate ringing phenomenon can be further prevented.
