Description
本発明は、屋根下地用断熱パネルに関するものである。 The present invention relates to a heat insulating panel for a roof base.
従来の屋根下地用断熱パネルとしては、例えば特許文献１に示すように、金属製の表面板と裏面板の間に断熱材を充填することにより構成されている。そして、この断熱パネルには、特許文献２に示すように隣接する断熱パネル同士を接続するために、その両側の側縁部に嵌合凸部及び嵌合凹部が形成されている。 As a conventional heat insulation panel for roof foundations, for example, as shown in Patent Document 1, a heat insulating material is filled between a metal front plate and a back plate. And as shown to patent document 2, in this heat insulation panel, in order to connect adjacent heat insulation panels, the fitting convex part and the fitting recessed part are formed in the side edge part of the both sides.
しかしながら、上記の断熱パネルは、両側の側縁部に嵌合凸部及び嵌合凹部を形成する必要があり鋼板の加工が難しいという問題がある。また、嵌合凸部、嵌合凹部またはその他の側縁部において断熱材が外部に露出した構成であるため、耐火性能の点で難がある。さらに嵌合凸部及び嵌合凹部が設けられた側縁部においては曲げに対する強度が強いものの、その他の側縁部においては必ずしも強度が強いとは言えない。 However, the above-described heat insulation panel has a problem in that it is difficult to process a steel sheet because it is necessary to form a fitting convex part and a fitting concave part on both side edge parts. Moreover, since it is the structure which the heat insulating material exposed outside in a fitting convex part, a fitting recessed part, or another side edge part, there exists a difficulty in the point of fireproof performance. Furthermore, although the strength against bending is strong in the side edge portion provided with the fitting convex portion and the fitting concave portion, the strength is not necessarily strong in the other side edge portion.
そこで本発明は、パネル構造を簡単にしながらも、耐火性能を向上させるとともに機械的強度を向上させることをその主たる所期課題とするものである。 Therefore, the main purpose of the present invention is to improve the fire resistance and mechanical strength while simplifying the panel structure.
すなわち本発明に係る屋根下地用断熱パネルは、一対の鋼板の間に断熱材を充填してなる平面視概略矩形状をなす屋根下地用断熱パネルであって、一方の鋼板が、平面視概略矩形状をなし、四辺が略直角に折り曲げられて概略箱形状をなすものであり、他方の鋼板が、平面視概略矩形状をなし、その各辺の周縁部が、前記一方の鋼板の折り曲げ部の自由端部に接触して、前記一方の鋼板の開口を閉塞するものであり、前記一方の鋼板の隣接する折り曲げ部同士の角部を耐火性を有する耐火性材料で被覆していることを特徴とする。 That is, the heat insulating panel for roof base according to the present invention is a heat insulating panel for roof base having a generally rectangular shape in plan view, in which a heat insulating material is filled between a pair of steel plates, and one steel plate is substantially rectangular in plan view. It has a shape, four sides are bent at a substantially right angle to form a substantially box shape, the other steel plate has a substantially rectangular shape in plan view, and the peripheral portion of each side is a bent portion of the one steel plate. in contact with the free end portion, wherein all SANYO for closing an opening of one of the steel sheet, that is coated with a refractory material having a refractory corners of adjacent bent portions of the one steel sheet Features.
このようなものであれば、概略箱形状をなす一方の鋼板の開口を他方の鋼板で閉塞するように構成しているので、鋼板の間に充填された断熱材が鋼板で覆われることになり、耐火性能を向上させることができる。また、一方の鋼板を概略箱形状に加工することによって、各辺の折り曲げ部が撓みを防止することから、機械的強度（剛性）を大きくすることができる。なお、これらの構成は、一方の鋼板の各辺を折り曲げることにより箱形状とすれば良いので、構造を複雑にすることもない。さらに、前記一方の鋼板の隣接する折り曲げ部同士の角部を耐火性を有する耐火性材料で被覆しているので、より一層耐火性能を向上させることができる。 In such a case, since the opening of one steel plate having a substantially box shape is configured to be closed with the other steel plate, the heat insulating material filled between the steel plates is covered with the steel plate. , Fireproof performance can be improved. In addition, by processing one of the steel plates into a substantially box shape, the bent portion of each side prevents bending, so that the mechanical strength (rigidity) can be increased. In addition, since these structures should just be made into a box shape by bending each edge | side of one steel plate, a structure is not complicated. Furthermore, since the corner | angular part between the adjacent bending parts of said one steel plate is coat | covered with the fireproof material which has fire resistance, fireproof performance can be improved further.
断熱パネルの撓みを可及的に小さくするためには、前記一方の鋼板が、屋根骨格を向くように当該屋根骨格に固定されるものであり、前記他方の鋼板に屋根構造体が固定されるものであることが望ましい。これならば概略箱形状をなす一方の鋼板が下側に位置することになり、この一方の鋼板は各辺の折り曲げ部により機械的強度が他方の鋼板よりも大きいので、パネル全体としての機械的強度を増すことができ、パネルの撓みを小さくすることができる。一方で、他方の鋼板を下側に位置するように固定する態様の場合には、他方の鋼板を一方の鋼板よりも厚くすることが考えられる。 In order to reduce the deflection of the heat insulation panel as much as possible, the one steel plate is fixed to the roof skeleton so as to face the roof skeleton, and the roof structure is fixed to the other steel plate. It is desirable to be a thing. If this is the case, one steel plate having a substantially box shape will be positioned on the lower side, and this one steel plate has a mechanical strength greater than that of the other steel plate due to the bent part of each side, so the mechanical strength of the entire panel The strength can be increased and the deflection of the panel can be reduced. On the other hand, in the case of fixing the other steel plate so as to be positioned on the lower side, it is conceivable to make the other steel plate thicker than one steel plate.
このように構成した本発明によれば、構造を複雑にすることなく、耐火性能を向上させるとともに機械的強度を向上させることができる。 According to the present invention configured as described above, the fire resistance can be improved and the mechanical strength can be improved without complicating the structure.
以下、本発明に係る屋根下地用断熱パネルの一実施形態について図面を参照して説明する。 Hereinafter, an embodiment of a thermal insulation panel for roof foundation according to the present invention will be described with reference to the drawings.
本実施形態に係る屋根下地用断熱パネル１００は、図１に示すように、下側に屋根骨格２００の鉄骨下地（具体的には鉄骨梁２０１）に固定されるとともに、上側に屋根材や屋根瓦等の屋根構造体３００が固定されるものであり、図２及び図３に示すように、平面視において概略矩形状をなすものである。 As shown in FIG. 1, the thermal insulation panel 100 for a roof base according to the present embodiment is fixed to a steel base (specifically, a steel beam 201) of a roof skeleton 200 on the lower side and a roof material or a roof on the upper side. A roof structure 300 such as a tile is fixed, and has a substantially rectangular shape in plan view as shown in FIGS. 2 and 3.
そして、この屋根下地用断熱パネル１００は、図１及び図４に示すように、一対の鋼板２、３の間に断熱材４を充填してなるものである。この屋根下地用断熱パネル１００は、縦寸法２０００ｍｍ、横寸法１０００ｍｍ、厚さ２５ｍｍである。なお、パネルサイズはこれに限られず適宜設計変更可能である。 And as shown in FIG.1 and FIG.4, this heat insulation panel 100 for roof base | substrates is filled with the heat insulating material 4 between a pair of steel plates 2 and 3. As shown in FIG. This heat insulation panel for roof foundation 100 has a vertical dimension of 2000 mm, a horizontal dimension of 1000 mm, and a thickness of 25 mm. The panel size is not limited to this, and the design can be changed as appropriate.
一方の鋼板である第１鋼板２は、例えば厚さ０．５ｍｍのガルバリウム鋼板等の合金メッキ鋼板から形成され、平面視において概略矩形状をなし、図５に示すように、四辺が略直角に折り曲げられて概略直方体状の箱形状をなすものである。そして、隣接する各辺の折り曲げ部２１ａ〜２１ｄの端部同士は略接触するように構成されている。また各辺の折り曲げ部２１ａ〜２１ｄの高さは互いに同じであり、折り曲げ部２１ａ〜２１ｄの自由端部２１１ａ〜２１１ｄ（上端部）は互いに同一平面上に位置する。 The first steel plate 2, which is one steel plate, is formed from an alloy-plated steel plate such as a galbarium steel plate having a thickness of 0.5 mm, for example, has a substantially rectangular shape in plan view, and has four sides substantially at right angles as shown in FIG. It is bent to form a substantially rectangular parallelepiped box shape. And the edge part of the bending parts 21a-21d of each adjacent edge | side is comprised so that it may contact substantially. The heights of the bent portions 21a to 21d on each side are the same, and the free ends 211a to 211d (upper end portions) of the bent portions 21a to 21d are located on the same plane.
他方の鋼板である第２鋼板３は、例えば厚さ１．２ｍｍのガルバリウム鋼板等の合金メッキ鋼板から形成され、平面視において概略矩形状をなす平板である。そして、図３及び図４に示すように、その各辺の周縁部３ａ〜３ｄは、前記第１鋼板２の折り曲げ部２１ａ〜２１ｄの自由端部２１１ａ〜２１１ｄ（上端部）に接触するように固定される。これにより第２鋼板３は、第１鋼板２の上部開口を閉塞する。 The second steel plate 3 that is the other steel plate is a flat plate that is formed of an alloy-plated steel plate such as a galvalume steel plate having a thickness of 1.2 mm, and has a substantially rectangular shape in plan view. And as shown in FIG.3 and FIG.4, the peripheral parts 3a-3d of each side are contacted with the free end parts 211a-211d (upper end part) of the bending parts 21a-21d of the said 1st steel plate 2. As shown in FIG. Fixed. As a result, the second steel plate 3 closes the upper opening of the first steel plate 2.
第１鋼板２及び第２鋼板３により形成される略直方体形状をなす空間には、断熱材４が充填される。この断熱材４の種類は、無機繊維系断熱材、発砲プラスチック系断熱材及び天然素材系断熱材の何れであっても良いが、本実施形態では、概略矩形状の定形性を有する例えば発砲プラスチック系断熱材のノンフロン型のフェノールフォームを用いている。 A space having a substantially rectangular parallelepiped shape formed by the first steel plate 2 and the second steel plate 3 is filled with a heat insulating material 4. The type of the heat insulating material 4 may be any of an inorganic fiber heat insulating material, a foamed plastic heat insulating material, and a natural material heat insulating material. In the present embodiment, for example, a foam plastic having a substantially rectangular shape. Non-Freon type phenolic foam is used.
次に本実施形態の屋根下地用断熱パネル１００の製造方法について図５を用いて簡単に説明する。 Next, the manufacturing method of the heat insulation panel 100 for roof foundations of this embodiment is demonstrated easily using FIG.
まず第１鋼板２を、概略矩形状をなす鋼板の四辺をそれぞれ折れ曲げ線に沿って一方向に屈曲させることにより形成する。なお、第１鋼板２の四つ角は各辺を屈曲させ易くするために、例えば隣接する各辺に直交するように直角状に切り欠いている（図６参照）。 First, the first steel plate 2 is formed by bending four sides of a substantially rectangular steel plate in one direction along a fold line. Note that the four corners of the first steel plate 2 are notched in a right angle so as to be orthogonal to each adjacent side, for example, in order to make the sides easily bend (see FIG. 6).
また、第１鋼板２の内部空間形状に合わせて断熱材４を用意する。そして、この断熱材４を第１鋼板２に収容すると共に、断熱材４及び第１鋼板２を接着剤で接着する。 Moreover, the heat insulating material 4 is prepared according to the internal space shape of the first steel plate 2. And while accommodating this heat insulating material 4 in the 1st steel plate 2, the heat insulating material 4 and the 1st steel plate 2 are adhere | attached with an adhesive agent.
次に、第１鋼板２の平面視形状に切断された第２鋼板３を第１鋼板２の開口を閉塞するように固定する。このとき、第１鋼板２の開口から外部に露出している断熱材４の上面に接着剤を塗布して、断熱材４及び第２鋼板３を接着させる。このようにして屋根下地用断熱パネル１００が製造される。 Next, the 2nd steel plate 3 cut | disconnected by the planar view shape of the 1st steel plate 2 is fixed so that the opening of the 1st steel plate 2 may be obstruct | occluded. At this time, an adhesive is applied to the upper surface of the heat insulating material 4 exposed to the outside from the opening of the first steel plate 2 to bond the heat insulating material 4 and the second steel plate 3. Thus, the heat insulation panel 100 for roof foundations is manufactured.
そしてこのように構成された屋根下地用断熱パネル１００は、図１に示すように、第１鋼板２が屋根骨格２００の鉄骨梁２０１側を向き、第２鋼板３が外側を向くように、鉄骨梁２０１にビスＢ１によって固定される。また外側を向く第２鋼板３には屋根構造体３００がビスＢ２によって固定される。この屋根構造体３００を固定するための固定ビスＢ２は、第２鋼板３及び断熱材４までねじ込まれており、第１鋼板２を貫通しないようにしている。このとき第２鋼板３の厚みを固定ビスＢ２が利くような厚みにしている。これにより、第１鋼板２の裏面からは、固定ビスＢ２が視認できないようにして屋根下地用断熱パネル１００が室内に露出する構造物であっても美観を損なわないようにしている。また、このとき屋根下地用パネルの裏面を室内側仕上げ面として、カラーリングするなどにより装飾性を付加することもできる。 And the heat insulation panel 100 for roof foundations comprised in this way is, as shown in FIG. 1, steel frame so that the 1st steel plate 2 may face the steel beam 201 side of the roof skeleton 200, and the 2nd steel plate 3 may face the outer side. It is fixed to the beam 201 with screws B1. The roof structure 300 is fixed to the second steel plate 3 facing outward by screws B2. The fixing screw B2 for fixing the roof structure 300 is screwed to the second steel plate 3 and the heat insulating material 4 so as not to penetrate the first steel plate 2. At this time, the thickness of the second steel plate 3 is set such that the fixed screw B2 works. Thereby, from the back surface of the 1st steel plate 2, even if it is a structure where the fixing screw B2 cannot be visually recognized and the heat insulation panel 100 for roof foundations is exposed indoors, aesthetics are not spoiled. Further, at this time, the back surface of the roof base panel can be used as a finished surface on the indoor side to add decoration, for example, by coloring.
＜本実施形態の効果＞
このように構成した本実施形態に係る屋根下地用断熱パネル１００によれば、概略箱形状をなす第１鋼板２の開口を第２鋼板３で閉塞するように構成しているので、鋼板２、３の間に充填された断熱材４が鋼板で覆われることになり、耐火性能を向上させることができる。また、第１鋼板２を概略箱形状に加工することによって、各辺の折り曲げ部２１ａ〜２１ｄが撓みを防止することから、機械的強度（剛性）を大きくすることができる。なお、これらの構成は、第１鋼板２の各辺を折り曲げることにより箱形状とすれば良いので、構造を複雑にすることもない。
<Effect of this embodiment>
According to the heat insulating panel for roof foundation 100 according to the present embodiment configured as described above, the second steel plate 3 is configured to close the opening of the first steel plate 2 having a substantially box shape. The heat insulating material 4 filled between 3 is covered with a steel plate, and the fire resistance can be improved. Moreover, since the bending parts 21a-21d of each side prevent bending by processing the 1st steel plate 2 in a substantially box shape, mechanical strength (rigidity) can be enlarged. In addition, since these structures should just be made into a box shape by bending each edge | side of the 1st steel plate 2, a structure is not complicated.

If it is this, the sealing property of the heat insulation panel 100 for roof foundations will improve, and fireproof performance can be improved.
また、第１鋼板及び第２鋼板をともに、平面視概略矩形状をなし、四辺が略直角に折り曲げられて概略箱形状をなすものとして、それらの開口を併せるようにして構成しても良い。つまり、前記実施形態において第２鋼板の周縁部を折れ曲がり部として、その折れ曲がり部の自由端部を第１鋼板の折れ曲がり部の自由端部と接触するようにして第１鋼板の開口を閉塞しても良い。 Further, both the first steel plate and the second steel plate may have a substantially rectangular shape in a plan view and be bent substantially at right angles to form a substantially box shape, and the openings may be combined. That is, in the said embodiment, the opening part of the 1st steel plate is obstruct | occluded so that the peripheral part of a 2nd steel plate may be a bending part, and the free end part of the bending part may contact the free end part of the bending part of a 1st steel plate. Also good.
