Description

本考案は、断熱パネルに所望の切り欠き部を設ける切断加工に用いられるガイドに関する。 The present invention relates to a guide used in a cutting process for providing a desired notch in a heat insulating panel.

ＲＣ（鉄筋コンクリート）造や、ＳＲＣ（鉄筋鉄骨コンクリート）造などの建物において、躯体に断熱性を付与して断熱構造とする手段としては、ポリウレタンフォームを躯体にスプレー等で吹き付ける工法が広く用いられていた。しかしながら、ポリウレタンフォームを躯体に吹き付ける工法は、工期が長い、５℃以下の環境下では施工できない、さらには、溶接火花による延焼のおそれが有る、等の問題があった。そこで、ポリウレタンフォームにかわって、ポリスチレン発泡体からなる断熱パネルを接着剤によって躯体に貼り付けて固定する工法が提案されている。 In buildings such as RC (reinforced concrete) and SRC (reinforced concrete), a method of spraying polyurethane foam onto the skeleton is widely used as a means of imparting heat insulating properties to the skeleton to form a heat insulating structure. It was. However, the method of spraying polyurethane foam onto the skeleton has problems that the construction period is long and the construction cannot be performed in an environment of 5 ° C. or lower, and that there is a risk of fire spreading due to welding sparks. Therefore, instead of polyurethane foam, a method has been proposed in which a heat insulating panel made of polystyrene foam is attached to the skeleton with an adhesive and fixed.

しかしながら、表面に凹凸を有する躯体表面に断熱層を設ける場合、凹部を埋めながら断熱層を形成することが可能なポリウレタンフォームとは異なり、断熱パネルの場合には、凸部を避けるために、特許文献１に開示されているようなカッターを用いて断熱パネルに切り欠き部を設け、断熱パネルを躯体に取り付けた後に、該切り欠き部を埋める必要があった。 However, when a heat insulating layer is provided on the surface of a skeleton having irregularities on the surface, unlike polyurethane foam, which can form a heat insulating layer while filling the recesses, in the case of a heat insulating panel, in order to avoid convex portions, a patent It was necessary to provide a notch in the heat insulating panel using a cutter as disclosed in Document 1, attach the heat insulating panel to the skeleton, and then fill the notch.

軽量気泡コンクリート（ＡＬＣ）パネルや押出成形セメント板（ＥＣＰ）に断熱パネルを取り付ける場合、これらのパネルは上下端部においてＺクリップで梁などの躯体に取り付けられているため、ＡＬＣパネルは上下中央に２箇所、ＥＣＰは上下で２箇所ずつの合計４箇所、断熱パネルに切り欠き部を設ける必要がある。よって、建物全体では、多数の切り欠き部を断熱パネルに形成する必要があり、一つずつ切断加工するのは非常に煩雑であった。 When attaching heat insulating panels to lightweight cellular concrete (ALC) panels or extruded cement boards (ECP), these panels are attached to the skeleton such as beams with Z clips at the upper and lower ends, so the ALC panels are centered vertically. It is necessary to provide notches in the heat insulating panel at two locations, two at the top and two at the bottom, for a total of four locations. Therefore, in the entire building, it is necessary to form a large number of notches in the heat insulating panel, and it is very complicated to cut one by one.

本考案は、断熱パネルを躯体等構造体に取り付ける断熱施工において、構造体表面の凸部に対応する切り欠き部を該断熱パネルに形成する際に用いられる切断加工ガイド（以下、「ガイド」と記す。）である。より具体的には、断熱パネルの端部に切り欠き部を設ける際に、該断熱パネルの端部を嵌め込んで用いられる部材である。 The present invention is a cutting processing guide (hereinafter referred to as "guide") used when forming a notch corresponding to a convex portion on the surface of a structure in the heat insulating panel in a heat insulating construction for attaching the heat insulating panel to a structure such as a skeleton. It is written.). More specifically, it is a member used by fitting the end portion of the heat insulating panel when providing a notch at the end portion of the heat insulating panel.

本考案のガイドは、天板と、該天板に連結された２枚の側板と、該２枚の側板のそれぞれに連結された２枚の案内板と、を有し、天板と２枚の側板とに連なる開口部を有していることを特徴とする。以下、本考案を図面を用いて詳細に説明する。 The guide of the present invention has a top plate, two side plates connected to the top plate, and two guide plates connected to each of the two side plates, and the top plate and two guide plates. It is characterized by having an opening connected to the side plate of the above. Hereinafter, the present invention will be described in detail with reference to the drawings.

図１、図２は、本考案のガイドの一実施形態を示す図であり、図１は斜視図、図２（ａ）は、図１中のＡ−Ａ’部位の断面図、図２（ｂ）は、矢印Ｃ方向から見た側板１２ａ側を正面として、図１中の矢印Ｂ方向から見た側面図、図２（ｃ）は、図２（ｂ）中の案内板１３ｂの部分拡大図である。 1 and 2 are views showing one embodiment of the guide of the present invention, FIG. 1 is a perspective view, FIG. 2 (a) is a cross-sectional view of a portion AA'in FIG. 1, and FIG. b) is a side view seen from the direction of arrow B in FIG. 1 with the side plate 12a side seen from the direction of arrow C as the front, and FIG. 2 (c) is a partially enlarged view of the guide plate 13b in FIG. 2 (b). It is a figure.

図１、図２に図示されるように、本考案のガイド１０は、天板１１と、２枚の側板１２ａ，１２ｂと、２枚の案内板１３ａ，１３ｂとを有している。 As shown in FIGS. 1 and 2, the guide 10 of the present invention has a top plate 11, two side plates 12a and 12b, and two guide plates 13a and 13b.

天板１１は、正方形又は長方形であり、相対する一対の側辺にそれぞれ、側板１２ａ、１２ｂが連結され、側板１２ａ，１２ｂは、天板１１に交差する方向に延びている。よって、天板１１の、側板１２ａ，１２ｂと連結する側辺に直交する方向の断面は略コ字型を呈している。尚、天板１１と側板１２ａ，１２ｂとのなす角度は９０°以下であり、図１、図２は９０°の場合である。 The top plate 11 is a square or a rectangle, and side plates 12a and 12b are connected to a pair of opposite side sides, respectively, and the side plates 12a and 12b extend in a direction intersecting the top plate 11. Therefore, the cross section of the top plate 11 in the direction orthogonal to the side side connected to the side plates 12a and 12b has a substantially U-shape. The angle formed by the top plate 11 and the side plates 12a and 12b is 90 ° or less, and FIGS. 1 and 2 show the case of 90 °.

側板１２ａ，１２ｂそれぞれの、天板１１との連結辺に対向する端辺には、案内板１３ａ，１３ｂが連結されており、案内板１３ａ，１３ｂは、側板１２ａ，１２ｂの端辺から外側に向かって傾斜している。即ち、図２（ｂ）において、案内板１３ａと１３ｂ間の距離は、側板１２ａ，１２ｂ側（Ｗ２）よりも端部側（Ｗ３）が大きくなるように、側板１２ａ，１２ｂから離れる方向に向かって互いに距離が広がるように、傾斜して側板１２ａ，１２ｂに連結されている。側板１２ａと案内板１３ａ、及び側板１２ｂと案内板１３ｂとのなす角度（θ）は、１４０°以上１６０°以下が好ましい（図２（ｃ））。図２（ｂ）に示すように、側面から見た場合に、本考案のガイド１０は、左右対称である。 Guide plates 13a and 13b are connected to the ends of each of the side plates 12a and 12b facing the connecting side with the top plate 11, and the guide plates 13a and 13b are outward from the end sides of the side plates 12a and 12b. It is tilted toward. That is, in FIG. 2B, the distance between the guide plates 13a and 13b is directed away from the side plates 12a and 12b so that the end side (W3) is larger than the side plates 12a and 12b (W2). They are inclined and connected to the side plates 12a and 12b so that the distance between them increases. The angle (θ) formed by the side plate 12a and the guide plate 13a, and the side plate 12b and the guide plate 13b is preferably 140 ° or more and 160 ° or less (FIG. 2C). As shown in FIG. 2B, the guide 10 of the present invention is symmetrical when viewed from the side surface.

さらに、本考案のガイド１０には、一方の側板１２ａから天板１１を横断して他方の側板１２ｂにわたる開口部１４を有している。開口部１４は、側板１２ａ，１２ｂそれぞれの、案内板１３ａ，１３ｂとの連結辺近傍まで形成されており、側板１２ａ、１２ｂそれぞれにおける開口部１４の領域は同じ位置に同じ形状、同じ寸法で形成されており、互いに重なり合う。図２（ａ）に示す側板１２ａ，１２ｂに形成された開口部１４の形状が、切断加工の対象である断熱パネルに設ける切り欠き部に対応する。即ち、矢印Ｃで示される正面から見た場合に、側板１２ａと案内板１３ａ、及び、側板１２ｂと案内板１３ｂとは、同じ形状、同じ寸法で互いに重なり合い、開口部１４の長さＬ１が切り欠き部の長さに相当する。また、側板１２ａ、１２ｂが互いに対向する側において、開口部１４の深さ（天板１１の下面から開口部１４の下端まで）Ｈ１が切り欠き部の高さに相当する。尚、開口部１４の深さＨ１は、側板１２ａ，１２ｂの高さ（天板１１の下面から側板１２ａ，１２ｂの下端まで）Ｈ２よりも若干短く、開口部１４と案内板１３ａ，１３ｂとの間に若干の距離を介在させることで、側板１２ａ，１２ｂの強度を高め、繰り返し使用によるガイド１０の変形や損傷を抑制することができる。 Further, the guide 10 of the present invention has an opening 14 that extends from one side plate 12a across the top plate 11 to the other side plate 12b. The opening 14 is formed up to the vicinity of the connecting side of each of the side plates 12a and 12b with the guide plates 13a and 13b, and the region of the opening 14 in each of the side plates 12a and 12b is formed at the same position with the same shape and the same dimensions. It is and overlaps with each other. The shape of the openings 14 formed in the side plates 12a and 12b shown in FIG. 2A corresponds to the notches provided in the heat insulating panel to be cut. That is, when viewed from the front indicated by the arrow C, the side plate 12a and the guide plate 13a, and the side plate 12b and the guide plate 13b overlap each other with the same shape and the same dimensions, and the length L1 of the opening 14 is cut. Corresponds to the length of the notch. Further, on the side where the side plates 12a and 12b face each other, the depth H1 of the opening 14 (from the lower surface of the top plate 11 to the lower end of the opening 14) corresponds to the height of the notch. The depth H1 of the opening 14 is slightly shorter than the height H2 of the side plates 12a and 12b (from the lower surface of the top plate 11 to the lower ends of the side plates 12a and 12b), and the opening 14 and the guide plates 13a and 13b are formed. By interposing a slight distance between them, the strength of the side plates 12a and 12b can be increased, and deformation and damage of the guide 10 due to repeated use can be suppressed.

また、開口部１４を挟む、天板１１及び側板１２ａ，１２ｂの長さＬ２，Ｌ３は、開口部１４の長さＬ１に応じて、ガイド１０が変形しにくい強度を示す範囲で適宜設定される。 Further, the lengths L2 and L3 of the top plate 11 and the side plates 12a and 12b sandwiching the opening 14 are appropriately set in a range showing strength at which the guide 10 is not easily deformed according to the length L1 of the opening 14. ..

図１、図２に示した実施形態においては、天板１１と側板１２ａ，１２ｂとのなす角度が９０°であり、側板１２ａ，１２ｂ間の距離は天板１１側（Ｗ１）から案内板１３ａ，１３ｂ側（Ｗ２）まで均一（Ｗ１＝Ｗ２）である。この場合、ガイド１０に嵌め込む断熱パネルの厚さをＴとすると、Ｗ１＝Ｗ２＝Ｔ×ｎ（ｎは１以上の整数）であり、側板１２ａ，１２ｂ間の距離が、断熱パネルの１枚又は複数枚の厚さに相当する。 In the embodiments shown in FIGS. 1 and 2, the angle formed by the top plate 11 and the side plates 12a and 12b is 90 °, and the distance between the side plates 12a and 12b is from the top plate 11 side (W1) to the guide plate 13a. , 13b side (W2) is uniform (W1 = W2). In this case, where T is the thickness of the heat insulating panel to be fitted into the guide 10, W1 = W2 = T × n (n is an integer of 1 or more), and the distance between the side plates 12a and 12b is one of the heat insulating panels. Or it corresponds to the thickness of a plurality of sheets.

また、本考案においては、図３に示すように、天板１１と側板１２ａ，１２ｂとのなす角度を９０°未満として、側板１２ａ，１２ｂ間の距離を、天板１１側（Ｗ１）より案内板１３ａ，１３ｂ側（Ｗ２）を短くする（Ｗ１＞Ｗ２）ことも可能である。この場合、ガイド１０に嵌め込む断熱パネルの厚さをＴとすると、Ｗ２≦Ｔ×ｎ≦Ｗ１（ｎは１以上の整数）であり、断熱パネルの１枚又は複数枚の厚さは、側板１２ａ，１２ｂ間の案内板１３ａ，１３ｂ側の距離（Ｗ２）以上で、且つ、側板１２ａ，１２ｂ間の天板１１側の距離（Ｗ１）以下である。この場合、Ｗ２＜Ｔ×ｎとしておけば、ガイド１０に断熱パネルを嵌め込んだ際に、ガイド１０の弾性によって、側板１２ａと案内板１３ａの連結辺と、側板１２ｂと案内板１３ｂとの連結辺と、に断熱パネルが強く挟持され、ガイド１０がずれにくくなるため、好ましい。 Further, in the present invention, as shown in FIG. 3, the angle formed by the top plate 11 and the side plates 12a and 12b is set to less than 90 °, and the distance between the side plates 12a and 12b is guided from the top plate 11 side (W1). It is also possible to shorten the plates 13a and 13b (W2) (W1> W2). In this case, where T is the thickness of the heat insulating panel to be fitted into the guide 10, W2 ≦ T × n ≦ W1 (n is an integer of 1 or more), and the thickness of one or more heat insulating panels is the side plate. The distance between the guide plates 13a and 13b (W2) between the side plates 12a and 12b is greater than or equal to the distance (W1) on the top plate 11 side between the side plates 12a and 12b. In this case, if W2 <T × n is set, when the heat insulating panel is fitted into the guide 10, the elastic of the guide 10 causes the connecting side of the side plate 12a and the guide plate 13a to be connected to the side plate 12b and the guide plate 13b. It is preferable because the heat insulating panel is strongly sandwiched between the sides and the guide 10 is less likely to shift.

また、案内板１３ａ，１３ｂ間の最大距離（案内板１３ａ，１３ｂの端部側の距離、Ｗ３）を、断熱パネルの１枚又は複数枚の厚さよりも大きくしておく（Ｔ×ｎ＜Ｗ３）ことにより、１枚以上の断熱パネルの端部をガイド１０の側板１２ａ，１２ｂ間に容易に嵌め込むことができる。 Further, the maximum distance between the guide plates 13a and 13b (distance on the end side of the guide plates 13a and 13b, W3) is made larger than the thickness of one or a plurality of heat insulating panels (T × n <W3). ) Therefore, the end portions of one or more heat insulating panels can be easily fitted between the side plates 12a and 12b of the guide 10.

図４、図５を用いて、図１、図２のガイドを用いた切断加工工程について説明する。 The cutting process using the guides of FIGS. 1 and 2 will be described with reference to FIGS. 4 and 5.

図４（ａ）、（ｂ）に示すように、断熱パネル２０を複数枚（図においては４枚）重ね、端部を天板１１が当接するまで、本考案のガイド１０の側板１２ａ，１２ｂ間に嵌め込む。この時、本考案のガイド１０は、側板１２ａ，１２ｂ間の距離（Ｗ１，Ｗ２）よりも、案内板１３ａ，１３ｂ間の端部側の距離（Ｗ３）が大きいため、案内板１３ａ，１３ｂの内側の面に断熱パネル２０の端部が当接し、スムーズに側板１２ａ，１２ｂに誘導され、嵌め込むことができる。尚、この場合の断熱パネル２０の４枚分の厚さ（Ｔ×ｎ）は側板１２ａ，１２ｂ間の距離（Ｗ１，Ｗ２）に等しい（Ｔ×ｎ＝Ｗ１，Ｗ２）。 As shown in FIGS. 4 (a) and 4 (b), a plurality of heat insulating panels 20 (4 in the figure) are stacked, and the side plates 12a and 12b of the guide 10 of the present invention are in contact with the top plate 11 at the ends. Fit in between. At this time, since the guide 10 of the present invention has a larger distance (W3) on the end side between the guide plates 13a and 13b than the distance (W1, W2) between the side plates 12a and 12b, the guide plates 13a and 13b The end portion of the heat insulating panel 20 abuts on the inner surface and is smoothly guided to the side plates 12a and 12b so that the heat insulating panel 20 can be fitted. In this case, the thickness (T × n) of the four heat insulating panels 20 is equal to the distance (W1, W2) between the side plates 12a and 12b (T × n = W1, W2).

次に、図４（ｃ）に示すように、ガイド１０の開口部１４に露出した断熱パネル２０を、開口部１４に沿ってカッター等で切断し、除去する。本考案のガイド１０を用いて切断加工される断熱パネル２０としては、ポリスチレン発泡体等の合成樹脂発泡体が挙げられるが、その他にも、切断加工できるものであれば、好ましく適用される。 Next, as shown in FIG. 4C, the heat insulating panel 20 exposed to the opening 14 of the guide 10 is cut along the opening 14 with a cutter or the like and removed. Examples of the heat insulating panel 20 to be cut using the guide 10 of the present invention include synthetic resin foams such as polystyrene foam, but other materials that can be cut are preferably applied.

図５は、図４（ｃ）の状態の断熱パネル２０から、ガイド１０を取り外した状態を示す斜視図であり、図５に示すように、本考案のガイド１０を用いて切断加工を行うことにより、複数枚の断熱パネル２０の同じ位置に、同じ形状、同じ大きさの切り欠き部２１を同時に形成することができる。また、切断に際しては、ガイド１０の開口部１４に沿って切断すればよいため、作業者が代わっても同じ精度で切断加工することができる。 FIG. 5 is a perspective view showing a state in which the guide 10 is removed from the heat insulating panel 20 in the state of FIG. 4 (c), and as shown in FIG. 5, cutting is performed using the guide 10 of the present invention. As a result, notches 21 having the same shape and the same size can be simultaneously formed at the same positions on the plurality of heat insulating panels 20. Further, since the cutting may be performed along the opening 14 of the guide 10, the cutting process can be performed with the same accuracy even if the operator changes.

尚、図４においては、断熱パネル２０を複数枚同時に切断加工する例を示したが、ガイド１０の幅（図２（ａ）に示す側板１２ａ，１２ｂ間の天板１１側の距離（Ｗ１））を断熱パネル２０の厚さに対応させることで、断熱パネル２０を１枚ずつ切断加工しても良い。 Although a plurality of heat insulating panels 20 are cut at the same time in FIG. 4, the width of the guide 10 (distance (W1) between the side plates 12a and 12b shown in FIG. 2A on the top plate 11 side). ) May correspond to the thickness of the heat insulating panel 20, so that the heat insulating panels 20 may be cut one by one.

また、切り欠き部２１を設ける位置が、断熱パネル２０の側辺に近い場合には、開口部１４を挟む天板１１及び側板１２ａ，１２ｂの長さＬ２又はＬ３（図２（ａ））を、切り欠き部２１の側辺からの距離に合わせておき、図６に示すように、ガイド１０の側板１２ａ，１２ｂ間に断熱パネル２０の端部を嵌め込む際に、ガイド１０の端部を断熱パネル２０の側辺に合わせることで、予めガイド１０の位置決めをしなくても、ガイド１０に高い位置精度で断熱パネル２０を嵌め込むことができる。 When the position where the cutout portion 21 is provided is close to the side side of the heat insulating panel 20, the lengths L2 or L3 (FIG. 2A) of the top plate 11 and the side plates 12a and 12b sandwiching the opening 14 are provided. As shown in FIG. 6, when the end of the heat insulating panel 20 is fitted between the side plates 12a and 12b of the guide 10, the end of the guide 10 is adjusted to the distance from the side of the notch 21. By aligning with the side side of the heat insulating panel 20, the heat insulating panel 20 can be fitted into the guide 10 with high position accuracy without positioning the guide 10 in advance.

上記したように、本考案のガイドを用いることにより、複数枚の断熱パネルに短時間で同じ切り欠きを高精度に切断加工することができ、断熱施工の作業性を大きく向上させることができる。 As described above, by using the guide of the present invention, the same notch can be cut with high accuracy in a plurality of heat insulating panels in a short time, and the workability of the heat insulating construction can be greatly improved.

本考案のガイド１０は、繰り返し使用に耐える耐久性を備え、図３の構成の場合には、弾性を有していることが好ましい。よって、鋼板などの金属製で構成されることが好ましいが、切断手段として熱線カッターを用いる場合には、熱線カッターが金属製のガイド１０に接触するとスパークが発生する。よって、ガイド１０が金属製で、且つ、熱線カッターを用いる場合には、ガイド１０に熱線カッターが接触しないように、ガイド１０の開口部１４を保護する必要がある。 The guide 10 of the present invention is durable enough to withstand repeated use, and in the case of the configuration of FIG. 3, it is preferable that the guide 10 has elasticity. Therefore, it is preferably made of a metal such as a steel plate, but when a heat ray cutter is used as the cutting means, sparks occur when the heat ray cutter comes into contact with the metal guide 10. Therefore, when the guide 10 is made of metal and a heat ray cutter is used, it is necessary to protect the opening 14 of the guide 10 so that the heat ray cutter does not come into contact with the guide 10.

図７、図８は、熱線カッターを使用する場合の本考案のガイドの実施形態であり、図７は斜視図、図８は図７中のＡ−Ａ’部位の断面図である。図７、図８に示すように、本実施形態においては、ガイド１０の側板１２ａ，１２ｂの外側に、該側板１２ａ，１２ｂに形成された開口部１４に沿って、該開口部１４から開口部１４内に向かって端部が突出するように、絶縁板１５が取り付けられている。絶縁板１５としては、ベークライトなどが好ましく用いられる。 7 and 8 are embodiments of the guide of the present invention when a heat ray cutter is used, FIG. 7 is a perspective view, and FIG. 8 is a cross-sectional view of a portion AA'in FIG. As shown in FIGS. 7 and 8, in the present embodiment, an opening is formed from the opening 14 on the outside of the side plates 12a and 12b of the guide 10 along the openings 14 formed in the side plates 12a and 12b. The insulating plate 15 is attached so that the end portion protrudes toward the inside of 14. Bakelite or the like is preferably used as the insulating plate 15.

本実施形態のガイド１０を、図４に示したように、断熱パネル２０の端部に取り付け、絶縁板１５の開口部に沿って切断すれば、熱線カッターをガイド１０に接触させることなく、断熱パネル２０を切断加工することができる。尚、図８に示す、絶縁板１５を取り付けた後のガイド１０の開口部１４の長さＬ４と深さ（天板１１の下面から開口部１４の下端までの高さ）Ｈ３が、断熱パネル２０に形成する開口部の長さ及び高さに相当する。よって、絶縁板１５を取り付ける前のガイド１０の開口部１４の長さＬ１及び深さＨ１は、絶縁板１５を取り付けた後の開口部１４の長さＬ４及び深さＨ３よりも長くなるように、即ち、絶縁板１５を取り付ける前のガイド１０の開口部１４は、断熱パネル２０に形成する切り欠き部２１よりも一回り大きくなるように形成しておく。 As shown in FIG. 4, if the guide 10 of the present embodiment is attached to the end of the heat insulating panel 20 and cut along the opening of the heat insulating plate 15, the heat ray cutter is heat-insulated without contacting the guide 10. The panel 20 can be cut. The length L4 and the depth (height from the lower surface of the top plate 11 to the lower end of the opening 14) H3 of the opening 14 of the guide 10 after the insulating plate 15 is attached are the heat insulating panel shown in FIG. Corresponds to the length and height of the opening formed in 20. Therefore, the length L1 and the depth H1 of the opening 14 of the guide 10 before the insulating plate 15 is attached are longer than the length L4 and the depth H3 of the opening 14 after the insulating plate 15 is attached. That is, the opening 14 of the guide 10 before attaching the insulating plate 15 is formed so as to be one size larger than the notch 21 formed in the heat insulating panel 20.
