以下、本願発明の外断熱形成具、外断熱構造物およびその構築方法について説明する。はじめに外断熱形成具について説明し、その後に、この外断熱形成具を用いた外断熱構造物およびその構築方法について説明する。なお、各実施の形態において同じ構成は同じ符号を付して説明し、異なった構成は異なった符号を付して説明する。   Hereinafter, the outer heat insulating forming tool, the outer heat insulating structure, and the construction method thereof according to the present invention will be described. First, an outer heat insulating forming tool will be described, and then an outer heat insulating structure using the outer heat insulating forming tool and a construction method thereof will be described. In each embodiment, the same configuration is described with the same reference numeral, and different configurations are described with different reference numerals.

図１〜図３は、外断熱形成具の実施の形態を示すものであり、この外断熱形成具１は適宜厚さで平面矩形の断熱板２と、この断熱板２の上下部における位置決め具３によって取り付けられた上端支持筋４と下端支持材５とから構成されている。   1 to 3 show an embodiment of an outer heat insulating forming tool. The outer heat insulating forming tool 1 includes a heat insulating plate 2 having a suitable thickness and a flat rectangular shape, and positioning tools at the upper and lower portions of the heat insulating plate 2. 3 is composed of an upper end support bar 4 and a lower end support member 5 attached to each other.

この断熱板２は無機系発泡材によって、例えばバルコニーなどの厚さと同じで、かつ自立できる幅に形成されたものであり、上部側の８つの貫通孔６と、下部側の３つの貫通孔６とに位置決め具３が嵌合されている。この位置決め具３は塩化ビニールなどの合成樹脂で形成された筒体７と、この筒体７の両端部外周に形成された鍔片８とから構成され、該鍔片８の一方は筒体７と一体形成されているが、他方は外周部の雄ネジ部９にねじ込まれて取外自在になっている。この上部側と下部側の位置決め具３とは同じ構成であり、単に径が異なっているだけである。   The heat insulating plate 2 is formed of an inorganic foam material, for example, to have the same thickness as a balcony or the like and to have a self-supporting width. The upper through hole 6 and the lower through hole 6 The positioning tool 3 is fitted to the two. The positioning tool 3 includes a cylinder 7 formed of a synthetic resin such as vinyl chloride, and flanges 8 formed on the outer periphery of both ends of the cylinder 7, and one of the flanges 8 is the cylinder 7. However, the other is screwed into a male screw portion 9 on the outer peripheral portion so that it can be removed. The positioning tools 3 on the upper side and the lower side have the same configuration, and are merely different in diameter.

この上部側の位置決め具３には、躯体からバルコニーなどの突出部に配筋される耐力筋と同径の上端支持筋４が挿入されている一方、下部側の位置決め具３には、前記の上端支持筋４よりも大径な下端支持材５が挿入されている。この下端支持材５は防錆機能を有するもの、または防錆処理を施したもの、例えばステンレス製のネジ節鉄筋であり、その両端部に支圧板１０、１１が設けられている。これら支圧板１０の一方は一体形成されて内側面にテーパが形成されているが、他方の支圧板１１はボルト１２で取外自在になっている。   The upper-side positioning tool 3 is inserted with an upper end supporting bar 4 having the same diameter as the load-bearing bars arranged from the housing to the protruding part such as a balcony. A lower end support member 5 having a diameter larger than that of the upper end support bar 4 is inserted. The lower end support member 5 is a member having a rust prevention function or a rust preventive treatment, for example, a stainless steel threaded bar, and bearing plates 10 and 11 are provided at both ends thereof. One of these pressure bearing plates 10 is integrally formed and has a taper formed on the inner surface, while the other pressure bearing plate 11 is detachable with a bolt 12.

また、上記の位置決め具３は耐火材で形成することもでき、この耐火材により断熱板２の貫通孔６における上端支持筋４と下端支持材５とが耐火被覆されるので火災などから保護される。この耐火材で形成された位置決め具３は材質のみが異なり、上記位置決め具３と同じ構成である。   In addition, the positioning tool 3 can be formed of a refractory material. Since the refractory material covers the upper end support bar 4 and the lower end support member 5 in the through hole 6 of the heat insulating plate 2, it is protected from fire and the like. The The positioning tool 3 formed of this refractory material is different in material only and has the same configuration as the positioning tool 3.

この上端支持筋４と下端支持材５とは、それぞれ上下の位置決め具３に挿入して断熱板２からの突出長さを決めた後に、位置決め具３内に接着剤１３を充填して固定する。この突出長さとは、断熱板２の両面から突出した長さであり、躯体側が長く突出し、突出部側がこれよりも短く突出している。なお、この上端支持筋４は８本、下端支持材５は３本に限定されるものではなく、これ以下またはこれ以上の本数であっても良い。   The upper end support bars 4 and the lower end support member 5 are inserted into the upper and lower positioning tools 3 to determine the protruding length from the heat insulating plate 2, and then the positioning tool 3 is filled with the adhesive 13 and fixed. . This protrusion length is the length which protruded from both surfaces of the heat insulation board 2, the housing side protrudes long, and the protrusion part side protrudes shorter than this. The number of the upper support bars 4 is not limited to eight, and the number of the lower support members 5 is not limited to three.

図３は、外断熱形成具１の組立方法を示したものであり、工場や現場において行うものである。はじめに断熱板２の上下の貫通孔６に位置決め具３を取り付ける。これは一方の鍔片８を取り外した筒体７を貫通孔６に挿入し、該筒体７の雄ネジ部９に前記鍔片８をねじ込んで取り付ける。次に、上部側の位置決め具３に上端支持筋４を挿入して、位置決めをした後、位置決め具３内に接着剤１３を充填して固定する。次に、一方の支圧板１１を取り外した下端支持材５を下側の位置決め具３に挿入するとともに、前記支圧板１１を下端支持材５の端部にボルト１２で取り付けた後、位置決め具３内に接着剤１３を充填して、外断熱形成具１を組立形成する。   FIG. 3 shows an assembling method of the outer heat insulation forming tool 1, which is performed in a factory or on-site. First, the positioning tool 3 is attached to the upper and lower through holes 6 of the heat insulating plate 2. The cylindrical body 7 from which one of the flange pieces 8 is removed is inserted into the through hole 6, and the flange piece 8 is screwed and attached to the male screw portion 9 of the cylindrical body 7. Next, after inserting the upper end support bar 4 into the positioning tool 3 on the upper side and positioning, the adhesive 13 is filled in the positioning tool 3 and fixed. Next, the lower end support member 5 from which one of the support plates 11 is removed is inserted into the lower positioning tool 3, and the support plate 11 is attached to the end of the lower end support member 5 with the bolts 12, and then the positioning tool 3. The inside is filled with the adhesive 13, and the outer heat insulation forming tool 1 is assembled and formed.

なお、上記の外断熱形成具１の実施の形態においては、上端支持筋４と下端支持材５とを位置決め具３に挿入したが、これらの上端支持筋４と下端支持材５とを、貫通孔６に直接挿入した外断熱形成具（図示せず）を形成することもできる。   In the embodiment of the outer heat insulation forming tool 1 described above, the upper end support bar 4 and the lower end support member 5 are inserted into the positioning tool 3, but the upper end support bar 4 and the lower end support member 5 are passed through. An external heat insulation forming tool (not shown) inserted directly into the hole 6 can also be formed.

また図４および図５は、上記の外断熱形成具１を使用した外断熱構造物１４の実施の形態を示したものである。この外断熱構造物１４は鉄筋コンクリート造の共同住宅であり、この共同住宅の躯体１５と、この躯体１５から突出した突出部１６であるバルコニー１７との境界部に外断熱形成具１が設置されて、バルコニー１７側からの熱橋を防いでいる。   4 and 5 show an embodiment of the outer heat insulating structure 14 using the outer heat insulating forming tool 1 described above. The outer heat insulating structure 14 is a reinforced concrete apartment house, and the outer heat insulating forming tool 1 is installed at the boundary between the housing 15 of the apartment house and the balcony 17 which is the protruding portion 16 protruding from the housing 15. The thermal bridge from the balcony 17 side is prevented.

この外断熱形成具１の断熱板２における上端支持筋４の一端部が、躯体１５側のスラブ筋１８と溶接接合されているとともに、他端部がバルコニーの上端筋１９と溶接接合されている。また下端支持材５は一方が梁２０内に埋設され、他方がバルコニー１７内に埋設されて、該バルコニー１７を支持している。また梁２０の前面（外側）に断熱材２１が貼り付けられた躯体１５の外面を覆う外断熱構造物１を構成している。   One end portion of the upper end support bar 4 in the heat insulating plate 2 of the outer heat insulation forming tool 1 is welded to the slab bar 18 on the side of the housing 15 and the other end is welded to the upper end bar 19 of the balcony. . One end of the lower end support member 5 is embedded in the beam 20 and the other end is embedded in the balcony 17 to support the balcony 17. Moreover, the outer heat insulation structure 1 which covers the outer surface of the housing 15 in which the heat insulating material 21 is attached to the front surface (outside) of the beam 20 is configured.

なお、上記の実施の形態において突出部１６はバルコニー１７として説明したが、このバルコニー１７を共有外廊下、庇またはパラペットとすることもできる。また上記の実施の形態においては上端支持筋４と下端支持材５とが位置決め具３に挿入された外断熱形成具１を使用したが、これらの上端支持筋４と下端支持材５とが貫通孔６に直接挿入された外断熱形成具（図示せず）を使用することもできる。   In the above-described embodiment, the protruding portion 16 has been described as the balcony 17. However, the balcony 17 can also be a shared outer corridor, a fence, or a parapet. Further, in the above embodiment, the outer heat insulating forming tool 1 in which the upper end support bar 4 and the lower end support member 5 are inserted into the positioning tool 3 is used. However, the upper end support bar 4 and the lower end support member 5 pass through. It is also possible to use an outer heat insulating forming tool (not shown) inserted directly into the hole 6.

次に、外断熱構造物の構築方法を図６および図７に基づいて説明する。この外断熱構造物の構築方法は、鉄筋コンクリート造の共同住宅の躯体１５とバルコニー１７との境界部に上記の外断熱形成具１を設置するものである。   Next, the construction method of the outer heat insulating structure will be described with reference to FIGS. In this construction method of the outer heat insulating structure, the outer heat insulating forming tool 1 is installed at the boundary between the housing 15 and the balcony 17 of a reinforced concrete apartment house.

まず、現場において、外断熱形成具１を上記と同じ方法で組立形成する。この外断熱形成具１は、鉄筋コンクリート造の共同住宅の躯体１５とバルコニー１７との境界部に設置する数だけ組立形成する。   First, on the site, the outer heat insulation forming tool 1 is assembled and formed by the same method as described above. The outer heat insulation forming tool 1 is assembled and formed in the number to be installed at the boundary between the housing 15 and the balcony 17 of the reinforced concrete apartment house.

次に、図６に示すように、型枠２２における躯体１５とバルコニー１７との境界部、すなわち型枠２２内に設置された梁前面の断熱材２１上面に、外断熱形成具１を横方向に連続して並べ、断熱板２同士を密接させて接続する（図示せず）。この断熱板２で躯体１５とバルコニー１７とが完全に遮断されるが、これらを一体的に接合するために、断熱板２の上端支持筋４と下端支持材５との一端側が躯体１５側の梁筋２３内に配筋されるとともに、他端側が突出部１６側に配筋されている。   Next, as shown in FIG. 6, the outer heat insulating forming tool 1 is laterally placed on the boundary between the housing 15 and the balcony 17 in the mold 22, that is, on the upper surface of the heat insulating material 21 in front of the beam installed in the mold 22. The heat insulating plates 2 are closely connected to each other (not shown). The casing 15 and the balcony 17 are completely cut off by the heat insulating plate 2, but in order to join them together, one end side of the upper end support bar 4 and the lower end support member 5 of the heat insulating plate 2 is on the side of the casing 15. The bar is arranged in the beam line 23, and the other end is arranged on the protruding part 16 side.

次に、図７に示すように、躯体側の型枠２２にスラブ筋２４を配筋して上端支持筋４の一端側に溶接接合するとともに、バルコニー側の型枠２２に鉄筋２５を配筋して、その上端筋２６を上端支持筋４の他端側に溶接接合する。そして、これらの鉄筋の配筋が完了した後に、型枠２２内にコンクリート２７を打設すると、図４に示すような外断熱構造物１４が構築される。   Next, as shown in FIG. 7, a slab bar 24 is arranged on the frame 22 on the housing side and welded to one end of the upper support bar 4 and a reinforcing bar 25 is arranged on the balcony side mold 22. Then, the upper end reinforcement 26 is welded to the other end side of the upper end support reinforcement 4. Then, after the arrangement of these reinforcing bars is completed, when concrete 27 is placed in the mold 22, the outer heat insulating structure 14 as shown in FIG. 4 is constructed.

なお、この外断熱構造物の構築方法の実施の形態は、バルコニー１７を対象として説明したが、共有外廊下、庇またはパラペットを対象とした場合でも同じ方法で形成する。また上記の実施の形態においては、上端支持筋４と下端支持材５とを位置決め具３に挿入した外断熱形成具１を使用したが、これらの上端支持筋４と下端支持材５とを貫通孔６に直接挿入した外断熱形成具（図示せず）を使用することもできる。   Although the embodiment of the method for constructing the outer heat insulating structure has been described for the balcony 17, the same method is used for the shared outer corridor, fence, or parapet. In the above embodiment, the outer heat insulating forming tool 1 in which the upper end support bar 4 and the lower end support member 5 are inserted into the positioning tool 3 is used. However, the upper end support bar 4 and the lower end support member 5 are penetrated. An external heat insulation forming tool (not shown) inserted directly into the hole 6 can also be used.
