Description

本発明は、建物の天井の断熱材の施工方法に関するものである。 The present invention relates to a method for constructing a heat insulating material for a ceiling of a building.

従来の建物上部の断熱構造としては、桁上端面上に板材を設置しその上部に断熱材を敷設する桁上断熱、屋根面の裏側に断熱材を敷設する屋根断熱、及び天井の上面に断熱材を敷設する天井断熱等がある。 Conventional heat insulation structure of the upper part of the building is the insulation on the girder in which the plate material is installed on the top surface of the girder and the heat insulation material is laid on the top, the heat insulation on the back side of the roof surface, and the insulation on the top surface of the ceiling There is a ceiling insulation that lays the material.

ところで、桁の上は空調配管やダウンライト等によるスペースを確保する必要がないため桁上断熱は他の工法に比べて断熱工事が容易にできるものである。この桁上断熱は図６に示すように、梁によって形成された天井軸組６の上部に断熱材３を載置するための板材５を設置し、小屋組７を行う前に断熱材３を該板材５上面に敷設することによって断熱工事がなされていた。（例えば特許文献１参照）
特開平１０−３３１２８０ By the way, since it is not necessary to secure a space by an air-conditioning pipe, a downlight or the like on the girder, the girder heat insulation can be easily insulated compared to other methods. As shown in FIG. 6, this girder insulation is provided with a plate material 5 for placing the heat insulating material 3 on the upper part of the ceiling shaft assembly 6 formed by the beams, and before the hut assembly 7, the heat insulating material 3 is installed. Heat insulation work was performed by laying on the upper surface of the plate material 5. (For example, see Patent Document 1)
JP-A-10-33280

しかし上記の施工方法によれば、断熱材３施工時の天候状況によっては断熱材３が風雨に晒されてしまい、断熱材３が劣化することで断熱材本来の機能を発揮できない状態になってしまうという問題がある。さらに、その問題を解消するために天井軸組６の上面に板材５を設置した直後に小屋組７を行い風雨を凌げる状況を確保してから、該板材５に断熱材３を敷設するために設けられた開口部を利用して断熱材３の敷設作業をする施工手段も考えられるが、屋根の勾配が緩やかである場合は板材５と屋根との間の空間が非常に狭いため施工が困難であり、また、開口部縁辺においても作業が非常に困難であるため十分に断熱材３を敷設できなく、作業効率も非常に悪いという問題が生じる。なお、図７中の符号８は野地板、７１は垂木、７２は小屋束を示すものである。 However, according to said construction method, depending on the weather conditions at the time of construction of the heat insulating material 3, the heat insulating material 3 is exposed to wind and rain, and the heat insulating material 3 is deteriorated so that the original function of the heat insulating material cannot be exhibited. There is a problem of end. Further, in order to solve the problem, in order to lay the heat insulating material 3 on the plate material 5 after securing the situation where the cabin set 7 is performed immediately after the plate material 5 is installed on the upper surface of the ceiling shaft assembly 6 and the wind and rain are surpassed. A construction means for laying the heat insulating material 3 using the provided opening is also conceivable. However, when the roof has a gentle slope, the space between the plate material 5 and the roof is very narrow, making the construction difficult. In addition, since the work is very difficult even at the edge of the opening, there is a problem that the heat insulating material 3 cannot be sufficiently laid and the work efficiency is very poor. In addition, the code | symbol 8 in FIG. 7 shows a field board, 71 shows a rafter, 72 shows a shed bundle.

本発明は、上記従来の問題に鑑みて発明したものであって、その目的とするところは、建物の小屋組を行った後であっても断熱材の敷設作業を容易にすることが可能となる天井の断熱材の施工方法を提供することにある。 The present invention has been invented in view of the above-described conventional problems, and the object of the present invention is that it is possible to facilitate the laying operation of the heat insulating material even after the building of the building is performed. It is in providing the construction method of the heat insulating material of the ceiling which becomes.

上記課題を解決するために請求項１に係る発明にあっては、天井を構成する梁１間に１対の木製の横架材２を架設し該梁１と該横架材２とで区切られた範囲に断熱材３を敷設する天井の断熱材の施工方法であって、前記横架材２に固定される固定片４１と該固定片４１に連設され断熱材３が載置される載置片４２とを備える支持具４を、前記載置片４２の先端が対向する横架材２との間で離間するよう一対の横架材２の下端部にそれぞれ設置し、この後、弾性変形可能な繊維系断熱材により構成された前記断熱材３の一側端部３１を、前記天井の下方から、一方の載置片４２の先端とこれに対向する横架材２との間を通して当該一方の前記載置片４２に載置し、この後、前記断熱材３を撓ませながら、他方の側端部３２を、他方の載置片４２の先端とこれに対向する横架材２との間を通して当該他方の載置片４２に載置することを特徴とするものである。 In order to solve the above-described problem, in the invention according to claim 1, a pair of wooden horizontal members 2 are installed between the beams 1 constituting the ceiling, and the beam 1 and the horizontal member 2 are separated. was range and a construction method of a ceiling insulation laying insulation 3, is provided continuously to the fixing piece 41 and the fixing piece 41 fixed to the front Kiyoko bridging member 2 heat insulator 3 is placed that placing the support 4 and a置片42, placed respectively on the lower ends of the pair of horizontal members 2 to be separated between the horizontal member 2 the leading edge of the front according置片42 is opposed, after the the one end 31 of the heat insulating material 3 constituted by elastically deformable fiber-based heat insulating material, from below the ceiling, the one rest piece 42 tips and the horizontal members 2 facing thereto Then, the other side end 32 is placed on the other placement piece 42 while bending the heat insulating material 3. It is characterized in that mounted on the other of the rest piece 42 through between the horizontal members 2 to tip and opposed thereto.

このような構成とすることで、断熱材３施工のための開口部を設ける必要がなくなるのは勿論のこと、断熱材３を載置するための板材５が不要となるものであり、断熱材３の敷設作業の作業性が著しく向上するものである。さらに、断熱材３が天井軸組６内部に収納されるので断熱材３の厚みを増大させても他の構造への影響が少なく高性能の断熱仕様に対応することが可能となるものであり、外観的にも非常に良好となるものである。 By adopting such a configuration, it is not necessary to provide an opening for constructing the heat insulating material 3, and the plate material 5 for placing the heat insulating material 3 is not necessary. The workability of the laying work 3 is remarkably improved. Furthermore, since the heat insulating material 3 is housed inside the ceiling frame 6, even if the thickness of the heat insulating material 3 is increased, there is little influence on other structures and it is possible to meet high performance heat insulating specifications. The appearance is also very good.

本発明によれば、天井軸組後であっても容易に天井の断熱材の敷設作業ができるので作業性が著しく向上するものであり、また、断熱材の高度な断熱仕様を実現できるので居住者の冷暖房にかかる費用を大幅に削減することを可能とするものであり、さらには断熱材の形状の設計上の自由度が向上するため断熱材の形状を同形同大とすることができ、断熱材の製造コストをも低減させることを可能とするものである。 According to the present invention, it is possible to easily lay the ceiling heat insulating material even after the ceiling shaft assembly, so that the workability is remarkably improved, and the high heat insulating specification of the heat insulating material can be realized. It is possible to greatly reduce the cost of cooling and heating by the person, and since the degree of freedom in designing the shape of the heat insulating material is improved, the shape of the heat insulating material can be made the same shape and the same size. Further, it is possible to reduce the manufacturing cost of the heat insulating material.

以下、本発明について添付図面に基づいて説明する。 The present invention will be described below with reference to the accompanying drawings.

本実施形態は、断面長矩形状の梁１にて天井軸組６が構成されており、該軸組６の上方に小屋組７が形成されているが、該小屋組７は和小屋組でも洋小屋組であってもよく特に限定されるものではない。図１に示すとおり、平行して設置される梁１には対の木製の横架材２が架設されており、該横架材２の端部は該梁１側面に固設される。特に図示しないが、該横架材２は梁１の長手方向に複数架設されており、横架材２と梁１からなる上面視略矩形状の区画が梁１の長手方向に連続して並んでいる。該梁１の長手方向に対する該横架材２の取付けピッチＰは夫々略同等になるように取付けることが好ましい。該区画内部には断熱材３が敷設されるため、梁の長手方向の取付けピッチＰを夫々略同等にしておくことで断熱材３の寸法の集約を図ることができ、断熱材３の製造コストの低減を図ることが可能となるからである。 In this embodiment, a ceiling shaft 6 is configured by a beam 1 having a rectangular cross section, and a shed 7 is formed above the shaft 6. It may be a cabin set and is not particularly limited. As shown in FIG. 1, a pair of horizontal wooden members 2 are installed on the beams 1 installed in parallel, and the ends of the horizontal members 2 are fixed to the side surfaces of the beams 1. Although not particularly illustrated, a plurality of the horizontal members 2 are installed in the longitudinal direction of the beam 1, and a substantially rectangular section in the top view composed of the horizontal member 2 and the beam 1 is continuously arranged in the longitudinal direction of the beam 1. It is out. The mounting pitch P of the horizontal member 2 with respect to the longitudinal direction of the beam 1 is preferably mounted so as to be substantially equal to each other. Since the heat insulating material 3 is laid inside the compartment, it is possible to consolidate the dimensions of the heat insulating material 3 by making the mounting pitches P in the longitudinal direction of the beams substantially equal, and the manufacturing cost of the heat insulating material 3 This is because it is possible to reduce this.

本来このようにして連続して区画が形成されるものであるが、以後の説明は連続して形成される多数の区画のうち一区画について説明することとする。 Originally, the compartments are formed continuously in this way, but in the following description, one of the many compartments formed continuously will be explained.

該梁１と該横架材２の固設方法は、該横架材２の長手方向の端部に面一になるように横架材受け２１を位置させ、梁１の長手方向に２つの横架材受け２１にて横架材２を挟むようにすると共に、該横架材受け２１と横架材２をクギ打ち固定し、さらに面一に形成された該横架材２及び該横架材受け２１の端部を梁１側面に当接して該横架材２と平行する方向にて該横架材受け２１を梁１側面にクギ打ち固定してなるものである。本実施形態では、このようにして該梁１と該横架材２が固設されるものであるが、梁１と横架材２の固設方法は本実施形態に限定されるものではない。 The beam 1 and the horizontal member 2 are fixed by positioning the horizontal member receiver 21 so as to be flush with the end of the horizontal member 2 in the longitudinal direction. The horizontal member 2 is sandwiched between the horizontal member receivers 21, the horizontal member receiver 21 and the horizontal member 2 are fixed in a nail, and the horizontal member 2 and the horizontal member formed on the same plane are fixed. The end of the frame support 21 is brought into contact with the side surface of the beam 1 and the horizontal material support 21 is fixed to the side surface of the beam 1 in a direction parallel to the horizontal frame 2. In this embodiment, the beam 1 and the horizontal member 2 are fixed in this manner, but the method of fixing the beam 1 and the horizontal member 2 is not limited to this embodiment. .

前記横架材２には、該横架材２の長手方向の両端部から内側に位置する箇所の下端部には支持具４が固設されており、該支持具４は固定片４１と固定片４１から連設するように立設される載置片４２とから成ると共に、該支持具４の断面は略Ｌ字形状にて形成されるものである。本実施形態において該支持具４は、金属片からなるものであるが、材質は特に限定されるものではない。さらに該固定片４１には、該横架材２の側面にクギ打ち固定が可能となるように複数の挿通穴が形成されている。このように構成することで、横架材２の側面下端部に支持具４を固設することが可能となる。 A support tool 4 is fixed to the horizontal member 2 at the lower end portion of the horizontal member 2 located on the inner side from both longitudinal ends of the horizontal member 2, and the support tool 4 is fixed to the fixing piece 41. The support piece 4 is formed in a substantially L-shaped cross section. In the present embodiment, the support 4 is made of a metal piece, but the material is not particularly limited. Furthermore, a plurality of insertion holes are formed in the fixing piece 41 so that it can be fixed to the side surface of the horizontal member 2 by nailing. By comprising in this way, it becomes possible to fix the support tool 4 to the side surface lower end part of the horizontal member 2.

本実施形態において該支持具４は断面Ｌ字形状にて形成されているが、特に限定されるものではなく、例えば固定片４１は板材がＬ字形状に屈曲した形状を有し、その屈曲部から載置片４２を突設させ断面略逆Ｔ字状を形成するものであってもよい。このように構成すれば、固定片４１を縦方向と横方向の２面で固定することが出来るのでより強固に固設することが可能となるものである。 In the present embodiment, the support 4 is formed in an L-shaped cross section, but is not particularly limited. For example, the fixed piece 41 has a shape in which a plate material is bent in an L shape, and the bent portion thereof. Alternatively, the mounting piece 42 may be protruded to form a substantially inverted T-shaped cross section. If comprised in this way, since the fixing piece 41 can be fixed by two surfaces of the vertical direction and a horizontal direction, it will become possible to fix more firmly.

前記支持具４の該載置片４２は相対する横架材２に向けて（すなわち、区画された内部に向けて）設置される。このようにして配置された前記載置片４２の上面には例えば繊維系断熱材３が載置され、梁１と横架材２に囲まれた範囲に該断熱材３が敷設されるが、該断熱材３の材質は特に限定されるものではない。該断熱材３の設置方法であるが、図２に示すように、梁１の長手方向に直角な断熱材３の辺の一側端部３１を横架材２に固設してある支持具４の載置片４２に載置し、対向する横架材２に設けられた支持具４の載置片４２先端よりも一側端部３１側に他方の側端部３２を近付けて断熱材３の本体部を撓ませ、且つこの他方の側端部３２を上方に移動させることで、該断熱材３全体をすべての該載置片４２上方に位置させることができ、弾力性を有する該断熱材３はその復元力によってその撓みがもとの状態に戻り、一側端部３１を載置した支持具４に対向する支持具４の載置片４２に断熱材３の他方の側端部３２を載置することができる。このようにして断熱材３をすべての支持具４の載置片４２上面に敷設することができるものであるが、該断熱材３は載置されるのみであっても該支持具４の載置片４２に接着剤にて固着されるものであっても特に限定されるものではない。 The mounting piece 42 of the support 4 is installed toward the opposite horizontal member 2 (that is, toward the partitioned interior). For example, the fiber-based heat insulating material 3 is placed on the upper surface of the placement piece 42 arranged as described above, and the heat insulating material 3 is laid in a range surrounded by the beam 1 and the horizontal member 2. The material of the heat insulating material 3 is not particularly limited. As shown in FIG. 2, the heat insulator 3 is installed by a support member in which one side end portion 31 of the side of the heat insulator 3 perpendicular to the longitudinal direction of the beam 1 is fixed to the horizontal member 2. 4, the other side end 32 is brought closer to the one end 31 side than the tip of the mounting piece 42 of the support 4 provided on the opposite horizontal member 2. 3, and the other side end 32 is moved upward, so that the entire heat insulating material 3 can be positioned above all the mounting pieces 42, and has elasticity. The heat insulating material 3 returns to its original state due to its restoring force, and the other side end of the heat insulating material 3 is placed on the placing piece 42 of the supporting tool 4 facing the supporting tool 4 on which the one side end portion 31 is placed. The part 32 can be placed. In this way, the heat insulating material 3 can be laid on the upper surfaces of the mounting pieces 42 of all the support tools 4, but even if the heat insulating material 3 is only mounted, the mounting of the support tools 4 is not possible. Even if it is fixed to the placing piece 42 with an adhesive, it is not particularly limited.

このようにして構成することによって、小屋組前に断熱材３を敷設する必要がなくなるので、断熱材３が風雨に晒されることによる劣化を回避することができる。また、従来必要であった天井軸組６上部の断熱材３を載置するための板材５が不要となり、天井軸組６を行った後に行う断熱材３の敷設作業の作業性を著しく向上させると共に、板材５に使用されていたコストの低減を図ることが出来る。さらに、断熱材３の支持具４を梁１の下部に位置させたので、天井軸組６内部に断熱材３を収納することが可能となり、外観の向上のみならず断熱材３の厚みの増大にも対応することができ、断熱仕様の高性能化にも対応することを可能とするものである。 By comprising in this way, since it becomes unnecessary to lay the heat insulating material 3 before a hut assembly, the deterioration by the heat insulating material 3 being exposed to a wind and rain can be avoided. Further, the plate material 5 for placing the heat insulating material 3 on the upper part of the ceiling shaft assembly 6 which is necessary in the past is not necessary, and the workability of the laying work of the heat insulating material 3 performed after the ceiling shaft assembly 6 is performed is remarkably improved. In addition, the cost used for the plate 5 can be reduced. Furthermore, since the support 4 of the heat insulating material 3 is positioned below the beam 1, it becomes possible to store the heat insulating material 3 inside the ceiling shaft assembly 6, and not only the appearance is improved but also the thickness of the heat insulating material 3 is increased. Therefore, it is possible to cope with the high performance of the heat insulation specification.

さらに加えて、従来の天井軸組後の断熱材３を敷設するための開口部に比べて断熱材３を搬入するための作業スペースが著しく増大したので、製造時の断熱材３の形状の設計上の自由度が向上し、例えば断熱材３の形状を区画の形状と略同形に設計し、部品点数の減少を図ることも可能となるので、製造コストの低減に資するものでもある。 In addition, since the work space for carrying the heat insulating material 3 is significantly increased compared to the opening for laying the heat insulating material 3 after the conventional ceiling shaft assembly, the design of the shape of the heat insulating material 3 at the time of manufacturing is designed. The upper degree of freedom is improved, and for example, the shape of the heat insulating material 3 can be designed to be substantially the same as the shape of the section, so that the number of parts can be reduced, which contributes to a reduction in manufacturing cost.

次に、他の実施形態について図３に基づいて説明する。なお、本実施形態は図１に示す実施形態と大部分において同じであるため、同じ部分については同符号を付して説明を省略し、主に異なる部分について説明する。 Next, another embodiment will be described with reference to FIG. In addition, since this embodiment is mostly the same as embodiment shown in FIG. 1, it attaches | subjects the same code | symbol about the same part, abbreviate | omits description, and mainly demonstrates a different part.

本実施形態は、フランジを上下水平とするＨ型鋼１１の上下に木材からなる上下端材１２を夫々ボルト連結にて一体化して形成される梁１にて天井軸組６が構成されている。その梁１に横架材２を架設し断熱材３を敷設するものであるが、その横架材２の固設方法について詳述する。横架材２は該Ｈ型鋼１１の下フランジ部の裏面（すなわち下フランジ部の上面）に載置され、梁１の長手方向には横架材受け２１にて横架材２を挟み梁１の長手方向における横架材２の移動を規制している。横架材受け２１と横架材２はクギ打ち固定等して固定することが好ましく、該横架材受け２１は該Ｈ型鋼１１の上下に形成された木製の上下端材１２にクギ打ち固定して固設されるものである。 In the present embodiment, the ceiling shaft assembly 6 is composed of beams 1 formed by integrating upper and lower end materials 12 made of wood on top and bottom of an H-shaped steel 11 whose flanges are vertically horizontal, respectively, by bolt connection. The horizontal member 2 is laid on the beam 1 and the heat insulating material 3 is laid. A method for fixing the horizontal member 2 will be described in detail. The horizontal member 2 is placed on the back surface of the lower flange portion of the H-shaped steel 11 (that is, the upper surface of the lower flange portion), and the horizontal member 2 is sandwiched by the horizontal member receiver 21 in the longitudinal direction of the beam 1. The movement of the horizontal member 2 in the longitudinal direction is regulated. It is preferable that the horizontal member receiver 21 and the horizontal member 2 are fixed by nailing, etc., and the horizontal member receiver 21 is fixed to the upper and lower ends 12 of the wood formed above and below the H-shaped steel 11 by nailing. And fixed.

該断熱材３は図４に示すように、略矩形状の断熱部３３の裏面（断熱材の下面）には梁１と平行になるように全長に亘って帯状の板状材３４が接着されて形成されるものである。帯状の板状材３４は弾力性を有する板材から成るものであり、支持具４の載置片４２の幅ａと略同じ幅を有すると共に、横架材２に設けてある支持具４の載置片４２の取り付けピッチＱと同等の取り付けピッチにて取り付けられるものであって、要するに、該板状材３４が双方の載置片４２に載置できる間隔にて固設されるものである。本実施形態においては、断熱部３３は繊維系断熱材にて形成され、板状材３４には金属や樹脂といった弾力性を有する材質にて形成されるものであるが、特に限定されるものではない。 As shown in FIG. 4, the heat insulating material 3 is bonded to the back surface (the lower surface of the heat insulating material) of a substantially rectangular heat insulating portion 33 with a strip-shaped plate material 34 over the entire length so as to be parallel to the beam 1. Is formed. The belt-like plate material 34 is made of a plate material having elasticity, has a width substantially the same as the width a of the mounting piece 42 of the support tool 4, and mounts the support tool 4 provided on the horizontal member 2. It is attached at an attachment pitch equivalent to the attachment pitch Q of the placing pieces 42, and in short, is fixed at an interval at which the plate-like material 34 can be placed on both placing pieces 42. In the present embodiment, the heat insulating portion 33 is formed of a fiber-based heat insulating material, and the plate-like material 34 is formed of a material having elasticity such as metal or resin, but is not particularly limited. Absent.

図５（ａ）及び図５（ｂ）に示すように、前記板状材３４の長手方向の一方の端面から載置片４２の突出長さｂと略同等の長さだけ接着剤による固定がなされておらず、断熱部３３と板状材３４がその他の部分を接着する接着剤の厚み程度の隙間部Ｓを介して形成されている。 As shown in FIGS. 5 (a) and 5 (b), the plate-like material 34 is fixed with an adhesive by a length substantially equal to the protruding length b of the mounting piece 42 from one end face in the longitudinal direction of the plate-like material 34. However, the heat insulating portion 33 and the plate-like material 34 are formed via a gap portion S having a thickness of about the thickness of the adhesive that bonds the other portions.

このような構成とすることで、載置片４２が該隙間部Ｓに被嵌されると共に、断熱部３３と板状材３４に挟持されることで該断熱材３（正しくは断熱部３３）が支持具４の載置片４２上面に強固に固設されるものである。 With such a configuration, the mounting piece 42 is fitted in the gap portion S, and is sandwiched between the heat insulating portion 33 and the plate-like material 34, thereby the heat insulating material 3 (correctly the heat insulating portion 33). Is firmly fixed to the upper surface of the mounting piece 42 of the support 4.

断熱材３の設置方法は前述した実施形態のものと同様に、一側端部３１を支持具４の載置片４２上面に載置させて他方の側端部３２を一側端部３１側に近付けるようにして撓ませ支持具４の載置片４２上面に載置させる（図５（ａ）参照）ものであるが、このとき上述した通り他方の側端部３２に形成された隙間部Ｓを載置片４２に被嵌させ設置するようにする。 The installation method of the heat insulating material 3 is the same as that of the above-described embodiment, the one side end portion 31 is placed on the upper surface of the placing piece 42 of the support 4, and the other side end portion 32 is placed on the one side end portion 31 side. And is placed on the upper surface of the mounting piece 42 of the support 4 (see FIG. 5A). At this time, the gap formed in the other side end 32 as described above.
