以下、この発明を図示の実施の形態に基づいて説明する。   The present invention will be described below based on the illustrated embodiments.

図１は、この発明の実施の形態に係る折り畳み式ダクト１を示す斜視図である。この折り畳み式ダクト１は主として、ダクト本体２と、補充部材３と、コーナーピース４とを備えている。   FIG. 1 is a perspective view showing a foldable duct 1 according to an embodiment of the present invention. The foldable duct 1 mainly includes a duct body 2, a replenishing member 3, and a corner piece 4.

ダクト本体２は、図２に示すように、４枚の壁板ユニット５を四方に配設して、断面が四角形な筒状とした角ダクトである。各壁板ユニット５は、図３に示すように、壁板５１と、第１のハゼ部材（ハゼ部材）５２と、第２のハゼ部材（ハゼ部材）５３と、第１のフランジ板（フランジ部材）５４と、第２のフランジ板（フランジ部材）５５とを備えている。   As shown in FIG. 2, the duct body 2 is a rectangular duct having four wall plate units 5 arranged in four directions and having a rectangular cross section. As shown in FIG. 3, each wall plate unit 5 includes a wall plate 51, a first gob member (gob member) 52, a second gob member (haze member) 53, and a first flange plate (flange). Member) 54 and a second flange plate (flange member) 55.

壁板５１は、断熱性で平ボード状のケイカル（珪酸カルシウム）板で構成され、その板厚は必要な断熱性能や強度などに応じて設定されているが、鉄板製やアルミ製などの従来のダクトの壁板の板厚（０．数ｍｍ〜数ｍｍ程度）に比べて、数倍以上厚いもの（２０ｍｍ程度以上）となっている。また、壁板５１の板面の大きさ、形状は、折り畳み式ダクト１の大きさ、形状に合わせて設定されている。つまり、素形材（素材）としてのケイカル板を折り畳み式ダクト１の大きさ、形状に合わせて所定の大きさ、形状に切断し、壁板５１としている。ここで、図３中の壁板５１における右側の側縁部を右側縁部５１ａとし、左側の側縁部を左側縁部５１ｂとし、上側の側縁部を上側縁部５１ｃとし、下側の側縁部を下側縁部５１ｄとする。   The wall board 51 is made of a heat-insulating, flat board-like calcium (calcium silicate) board, and the thickness of the wall board 51 is set according to the required heat insulation performance, strength, etc. Compared to the wall thickness of the duct wall plate (approximately several millimeters to several millimeters), the thickness is several times or more thick (approximately 20 mm or more). Further, the size and shape of the wall surface of the wall plate 51 are set in accordance with the size and shape of the folding duct 1. That is, a calcium plate as a raw material (raw material) is cut into a predetermined size and shape according to the size and shape of the folding duct 1 to form the wall plate 51. Here, the right side edge of the wall plate 51 in FIG. 3 is the right edge 51a, the left side edge is the left edge 51b, the upper side edge is the upper edge 51c, and the lower side edge 51c is the lower edge. Let the side edge be the lower edge 51d.

第１のハゼ部材５２は鉄板製で、装着板５２ａとハゼ板５２ｂとから構成されている。装着板５２ａは、断面がコ字状で壁板５１の右側縁部５１ａの側縁に沿って延び、コ字状の開口幅が壁板５１の板厚とほぼ同寸法に設定されている。また、ハゼ板５２ｂは装着板５２ａの側片５２ａ１とほぼ同寸法で、この側片５２ａ１に接合され、外側（装着板５２ａの非開口側）の縁部にダブルハゼ（第１のハゼ）５２ｂ１が形成されている。このダブルハゼ５２ｂ１は断面がカール状で、装着板５２ａの長手方向つまり右側縁部５１ａの側縁に沿って延び、後述するシングルハゼ（第２のハゼ）５３ｂ１と回動自在に係合するようになっている。 The first goby member 52 is made of an iron plate and includes a mounting plate 52a and a gouge plate 52b. The mounting plate 52 a has a U-shaped cross section and extends along the side edge of the right edge 51 a of the wall plate 51, and the U-shaped opening width is set to be substantially the same as the plate thickness of the wall plate 51. Further, goby plate 52b is substantially the same dimensions as the side pieces 52a 1 of the mounting plate 52a, is joined to the side pieces 52a 1, outside Daburuhaze the edge of the (non-opening side of the mounting plate 52a) (first goby) 52 b 1 are formed. The double goby 52b 1 has a curled cross section, extends along the longitudinal direction of the mounting plate 52a, that is, along the side edge of the right edge 51a, and rotatably engages with a single goby (second goby) 53b 1 described later. It is like that.

このような第１のハゼ部材５２は、長尺の素形材を切断して、所定の長さに設定されている。すなわち、上記のような装着板５２ａとハゼ板５２ｂから構成される長尺の（例えば数ｍの）素形材を製造し、この素形材を壁板５１の右側縁部５１ａの長さに合わせて切断して、所定の長さにしている。そして、このような第１のハゼ部材５２が、図４〜６に示すように、装着板５２ａの開口部が壁板５１の右側縁部５１ａに装着した状態で、つまり右側縁部５１ａを板厚方向に挟持（カバー）するように、取り付けられている。   Such a first goby member 52 is set to a predetermined length by cutting a long material. That is, a long (for example, several m) shaped material composed of the mounting plate 52a and the goby plate 52b as described above is manufactured, and this shaped material is made to the length of the right edge 51a of the wall plate 51. They are cut together to a predetermined length. Then, as shown in FIGS. 4 to 6, such a first goby member 52 is in a state where the opening of the mounting plate 52 a is mounted on the right edge 51 a of the wall plate 51, that is, the right edge 51 a is a plate. It is attached so as to be sandwiched (covered) in the thickness direction.

第２のハゼ部材５３は、シングルハゼ５３ｂ１を除いて第１のハゼ部材５２とほぼ同等の構成であるため、主として異なる点について説明する。すなわち、ハゼ板５３ｂの外側（装着板５３ａの非開口側）の縁部にシングルハゼ５３ｂ１が形成されている。このシングルハゼ５３ｂ１は断面がカール状で、ダブルハゼ５２ｂ１と回動自在に係合するようになっている。すなわち、図７に示すように、ダブルハゼ５２ｂ１とシングルハゼ５３ｂ１とが係合して回動自在なスピンハゼ（角部）２Ａが形成されている。また、ダブルハゼ５２ｂ１とシングルハゼ５３ｂ１との間には、気密性を保つためのチューブ状のガスケット６が装着されている。このような第２のハゼ部材５３が、図４〜６に示すように、装着板５３ａの開口部が壁板５１の左側縁部５１ｂに装着した状態で、つまり左側縁部５１ｂを板厚方向に挟持するように、取り付けられている。 Since the second goby member 53 has substantially the same configuration as the first goby member 52 except for the single goby 53b 1 , different points will be mainly described. That is, single goby 53b 1 is formed on the edge of the outer (non-opening side of the mounting plate 53a) of goby plate 53b. The single goby 53b 1 has a curled cross section and is configured to engage with the double gob 52b 1 in a rotatable manner. That is, as shown in FIG. 7, the spin goby (corner portion) 2A that is rotatable by the engagement of the double goby 52b 1 and the single gouse 53b 1 is formed. Further, a tube-like gasket 6 for keeping airtightness is mounted between the double goby 52b 1 and the single goby 53b 1 . As shown in FIGS. 4 to 6, such a second goby member 53 is in a state where the opening of the mounting plate 53 a is mounted on the left edge 51 b of the wall plate 51, that is, the left edge 51 b is arranged in the thickness direction. It is attached so that it may be pinched.

そして、後述するようにして各壁板ユニット５を連結し、例えば図７（ａ）に示すように、隣接するハゼ板５２ｂとハゼ板５３ｂとが直角に位置する状態（ダクト本体２が筒状に展開した状態）から、第２のハゼ部材５３のハゼ板５３ｂを第１のハゼ部材５２のハゼ板５２ｂ側に押す。すると、ダブルハゼ５２ｂ１を軸としてシングルハゼ５３ｂ１が回動し、つまりスピンハゼ２Ａが回動し、図７（ｂ）に示すように、第２のハゼ部材５３が第１のハゼ部材５２側に移動する。以上のような第１のハゼ部材５２と第２のハゼ部材５３とによって折り畳み式ダクト用ハゼ継手が構成される。 Then, as will be described later, the wall plate units 5 are connected, and for example, as shown in FIG. 7A, the adjacent goby plate 52b and goby plate 53b are positioned at right angles (the duct body 2 is cylindrical). 2), the goby plate 53b of the second gouge member 53 is pushed toward the gouge plate 52b side of the first gouge member 52. Then, the single goby 53b 1 rotates about the double goby 52b 1 , that is, the spin gob 2A rotates, and the second gob member 53 moves toward the first gob member 52 as shown in FIG. 7B. Moving. The first gob member 52 and the second gob member 53 as described above constitute a foldable duct gob joint.

第１のフランジ板５４は鉄板製で、断面が略Ｌ字形のアングル材状であり、取付面部５４ａには、後述するコーナーピース４を固定するために凸状に折り曲げられた凸部５４ｂが長手方向に沿って形成されている。このような第１のフランジ板５４は、長尺の素形材を切断して、所定の長さに設定されている。すなわち、上記のような断面形状を有する長尺の（例えば数ｍの）素形材を製造し、この素形材を壁板５１の上側縁部５１ｃの長さに合わせて切断して、所定の長さにしている。また、図中５４ｄは、フランジ面部５４ｃから取付面部５４ａ側に垂直に折り曲げられたカシメ部である。   The first flange plate 54 is made of an iron plate and has an angle material shape with a substantially L-shaped cross section. The mounting surface portion 54a has a convex portion 54b bent in a convex shape to fix a corner piece 4 described later. It is formed along the direction. Such a first flange plate 54 is set to a predetermined length by cutting a long shaped material. That is, a long (for example, several m) shaped material having a cross-sectional shape as described above is manufactured, and this shaped material is cut in accordance with the length of the upper edge portion 51c of the wall plate 51 to obtain a predetermined shape. Of length. Reference numeral 54d in the figure denotes a caulking portion that is bent vertically from the flange surface portion 54c toward the mounting surface portion 54a.

このような第１のフランジ板５４が、図４〜６に示すように、壁板５１の上側縁部５１ｃに沿って配設されている。すなわち、取付面部５４ａが上側縁部５１ｃの板面５１ｅ側の上縁に沿って配置され、両端部がハゼ部材５２、５３で覆われた状態で、ビス７によって共締めされている。これによって、第１のフランジ板５４とハゼ部材５２、５３とが壁板５１に固定されている。   Such a 1st flange board 54 is arrange | positioned along the upper side edge part 51c of the wall board 51, as shown to FIGS. That is, the attachment surface portion 54 a is disposed along the upper edge of the upper edge portion 51 c on the plate surface 51 e side, and both ends are covered with the goby members 52 and 53 and fastened together with the screws 7. As a result, the first flange plate 54 and the goby members 52 and 53 are fixed to the wall plate 51.

第２のフランジ板５５は、第１のフランジ板５４と同等な構成で、第１のフランジ板５４と同様にして、壁板５１の下側縁部５１ｄに沿って配設されている。そして、後述するようにして各壁板ユニット５を連結し、各壁板ユニット５を筒状に展開すると、図２、８に示すように、各第１のフランジ板５４のフランジ面部５４ｃが同一平面上で四角い環状に配置されて、上側のフランジ２Ｂを形成する。同様に、各第２のフランジ板５５のフランジ面部５５ｃが同一平面上で四角い環状に配置されて、下側のフランジ２Ｂを形成するようになっている。   The second flange plate 55 has the same configuration as the first flange plate 54 and is disposed along the lower edge portion 51 d of the wall plate 51 in the same manner as the first flange plate 54. Then, as will be described later, when the wall plate units 5 are connected and each wall plate unit 5 is expanded into a cylindrical shape, the flange surface portions 54c of the first flange plates 54 are the same as shown in FIGS. Arranged in a square ring shape on the plane, the upper flange 2B is formed. Similarly, the flange surface portions 55c of the second flange plates 55 are arranged in a square ring shape on the same plane to form the lower flange 2B.

このような壁板ユニット５を４枚連結してダクト本体２が形成されている。すなわち、隣接する壁板ユニット５のダブルハゼ５２ｂ１とシングルハゼ５３ｂ１とを係合し、４枚の壁板ユニット５を環状に連結している。さらに、ダブルハゼ５２ｂ１とシングルハゼ５３ｂ１との間にガスケット６を挿入、装着して、ダクト本体２が形成されている。そして、ダブルハゼ５２ｂ１とシングルハゼ５３ｂ１との係合部であるスピンハゼ２Ａを回動させて各壁板ユニット５を展開すると、図８に示すように、断面が四角形なダクト本体２が形成される。また、この状態から、スピンハゼ２Ａを回動させて壁板ユニット５を重ねるようにすると、図９に示すように、ダクト本体２が折り畳まれた状態となる。 The duct body 2 is formed by connecting four such wall plate units 5. That is, the double goby 52b 1 and the single goby 53b 1 of the adjacent wall plate units 5 are engaged, and the four wall plate units 5 are connected in an annular shape. Furthermore, inserting a gasket 6 between the Daburuhaze 52 b 1 and the single goby 53b 1, by mounting the duct body 2 is formed. Then, when the wall plate unit 5 is developed by rotating the spin goby 2A that is the engaging portion between the double goby 52b 1 and the single goby 53b 1 , a duct body 2 having a quadrangular cross section is formed as shown in FIG. The Further, from this state, when the spin goby 2A is rotated to overlap the wall plate unit 5, the duct body 2 is folded as shown in FIG.

補充部材３は、ダクト本体２を筒状に展開した状態で隣接する壁板ユニット５の側縁部と側縁部との隙間を埋める部材である。すなわち、図１０に示すように、断面が四角形な筒状で可撓性（変形能）を有する断熱ケース３１の筒内に、グラスウールなどの断熱材３２が充填され、全体が断熱性の高い部材となっている。そして、図８に示すように、隣接する壁板ユニット５の側縁部と側縁部との隙間に配置した際に、隣接する壁板５１の側端と側端との空隙（内角）を埋めるように、補充部材３の断面形状が設定されている。すなわち、補充部材３を配置することよって、壁板５１が隙間なく環状に連結するようになっている。   The replenishing member 3 is a member that fills a gap between the side edge portions of the adjacent wall plate units 5 in a state where the duct body 2 is expanded in a cylindrical shape. That is, as shown in FIG. 10, a cylinder of a heat insulating case 31 having a quadrangular cross section and having flexibility (deformability) is filled with a heat insulating material 32 such as glass wool, and the whole is a highly heat insulating member. It has become. And when arrange | positioning in the clearance gap between the side edge part of the adjacent wall board unit 5 and a side edge part as shown in FIG. 8, the space | gap (inner angle) of the side edge of the adjacent wall board 51 and a side edge is made. The cross-sectional shape of the replenishing member 3 is set so as to be filled. That is, by arranging the replenishing member 3, the wall plate 51 is connected in an annular shape without a gap.

コーナーピース４は金属製で、図１１に示すように、略平板状でＬ字形をしており、角部には取付孔４ａが形成されている。また、外周縁と内周縁とにはそれぞれ、板面に対して垂直な外周縁片４ｂと内周縁片４ｃとが形成され、角部の内縁には、板面に対してほぼ垂直に延びる突出片４ｄが形成されている。そして、上記のようにして補充部材３が配置されたダクト本体２の各コーナに、このコーナーピース４を配設するものである。すなわち、図１２に示すように、補充部材３の角に突出片４ｄを当接した状態で、板面を各フランジ板５４、５５のフランジ面部５４ｃ、５５ｃ上に配置する。この際、凸部５４ｂ、５５ｂが内周縁片４ｃの直上に位置し、各フランジ板５４、５５のカシメ部５４ｄ、５５ｄを外周縁片４ｂ側に折り曲げてカシメる。これにより、コーナーピース４が第１のフランジ板５４または第２フランジ板５５に固定され、コーナーピース４によってダクト本体２の筒状状態が維持されるとともに、ダクト本体２とコーナーピース４とによって補充部材３が挟持される。   The corner piece 4 is made of metal and has a substantially flat L shape as shown in FIG. 11, and mounting holes 4a are formed at the corners. Further, an outer peripheral edge piece 4b and an inner peripheral edge piece 4c that are perpendicular to the plate surface are respectively formed on the outer peripheral edge and the inner peripheral edge, and a protrusion that extends substantially perpendicular to the plate surface is formed on the inner edge of the corner portion. A piece 4d is formed. And this corner piece 4 is arrange | positioned in each corner of the duct main body 2 in which the supplementary member 3 is arrange | positioned as mentioned above. That is, as shown in FIG. 12, the plate surfaces are arranged on the flange surface portions 54 c and 55 c of the flange plates 54 and 55 with the protruding pieces 4 d in contact with the corners of the replenishment member 3. At this time, the convex portions 54b and 55b are positioned immediately above the inner peripheral edge piece 4c, and the caulking portions 54d and 55d of the flange plates 54 and 55 are bent to the outer peripheral edge piece 4b side and caulked. As a result, the corner piece 4 is fixed to the first flange plate 54 or the second flange plate 55, and the cylindrical state of the duct body 2 is maintained by the corner piece 4, and replenished by the duct body 2 and the corner piece 4. The member 3 is clamped.

次に、このような構成の折り畳み式ダクト１の取付方法などについて説明する。まず、ダクトを生産する工場や保管倉庫などで上記のようにして形成したダクト本体２を、スピンハゼ２Ａを回動させて折り畳み、その状態で取付現場（建設現場など）まで搬送する。次に、スピンハゼ２Ａを回動させて各壁板ユニット５を展開し、ダクト本体２を筒状にする。続いて、壁板ユニット５の側縁部と側縁部との隙間に補充部材３を配置し、上記のようにしてコーナーピース４を取り付ける。これにより、ダクト本体２と補充部材３とコーナーピース４とが一体化される。このような折り畳み式ダクト１のフランジ２Ｂの外面（フランジ面部５４ｃ、５５ｃの外向き側の面）にガスケットを取り付けて、所望の位置に取り付ける（吊り込む）。そして、フランジ２Ｂを介して他のダクトなどと接続するものである。   Next, a method for attaching the folding duct 1 having such a configuration will be described. First, the duct main body 2 formed as described above in a factory or a storage warehouse for producing ducts is folded by rotating the spin goby 2A, and in that state, is conveyed to an installation site (such as a construction site). Next, the spin goby 2A is rotated to unfold each wall plate unit 5, and the duct body 2 is formed into a cylindrical shape. Subsequently, the replenishing member 3 is disposed in the gap between the side edge portion of the wall plate unit 5 and the corner piece 4 is attached as described above. Thereby, the duct main body 2, the replenishment member 3, and the corner piece 4 are integrated. A gasket is attached to the outer surface of the flange 2B of the foldable duct 1 (the outward surface of the flange surface portions 54c and 55c), and is attached (hanged) at a desired position. And it connects with another duct etc. via the flange 2B.

以上のように、この折り畳み式ダクト１によれば、断熱性の壁板５１でダクト１の周壁が構成されているため、このダクト１を取付現場に搬入して取り付けることで、断熱性のダクト１が取り付けられたことになる。つまり、取付現場においてダクト１に断熱処理を施す必要がなくなり、断熱処理に要する労力と時間とをなくすことができるとともに、取付現場における断熱材の廃材の発生をなくすことができる。しかも、ダクト本体２を筒状に展開するだけでフランジ２Ｂが形成されるため、別途フランジを設ける必要がなく、接続作業を容易、迅速に行うことができる。   As described above, according to the foldable duct 1, the peripheral wall of the duct 1 is configured by the heat insulating wall plate 51. Therefore, the duct 1 is brought into the installation site and attached, so that the heat insulating duct 1 1 is attached. That is, it is not necessary to heat-insulate the duct 1 at the installation site, so that labor and time required for the heat-insulating process can be eliminated, and generation of waste material of heat-insulating material at the installation site can be eliminated. Moreover, since the flange 2B is formed simply by expanding the duct body 2 into a cylindrical shape, it is not necessary to provide a separate flange, and the connection work can be performed easily and quickly.

また、ハゼ部材５２、５３が壁板５１の側縁部５１ａ、５１ｂを挟持（カバー）するように配設されているため、ハゼ部材５２、５３の配設が強固になるとともに、壁板５１が脆い材質などであってもその側縁部５１ａ、５１ｂがハゼ部材５２、５３で保護、補強される。しかも、隣接する壁板ユニット５の側縁部と側縁部との隙間を埋めるように補充部材３が配設されているため、全周が隙間なく断熱材で覆われ、ダクト１の断熱性が向上する。さらには、折り畳み式ダクト１の吊り込みの精度不良によってダクト１（ダクト本体２）に歪みが発生する場合であっても、この歪みが補充部材３で吸収され、ダクト本体２への応力を抑制することが可能となる。   Further, since the goby members 52 and 53 are arranged so as to sandwich (cover) the side edge portions 51a and 51b of the wall plate 51, the arrangement of the goze members 52 and 53 is strengthened, and the wall plate 51 is also provided. Even if the material is brittle, the side edges 51a and 51b are protected and reinforced by the goby members 52 and 53. Moreover, since the replenishing member 3 is disposed so as to fill the gap between the side edge portions of the adjacent wall plate units 5, the entire periphery is covered with a heat insulating material without any gap, and the heat insulating property of the duct 1. Will improve. Furthermore, even if the duct 1 (duct body 2) is distorted due to poor accuracy of the folding duct 1 being suspended, this distortion is absorbed by the replenishing member 3 and the stress on the duct body 2 is suppressed. It becomes possible to do.

また、ダクト１の大きさや形状が異なる場合であっても、同じ素形材を使用することが可能となる。すなわち、ダクト１の大きさや形状に合わせて、上記のように素形材を切断し、所定の大きさや形状の壁板５１や、所定の長さのハゼ部材５２、５３、フランジ板５４、５５を形成する。そして、これらを組み付けることで所定の大きさ、形状の壁板ユニット５、さらにはダクト本体２、ダクト１を形成することができる。この結果、素形材を共用化して、製造コストや保管、管理コストなどを削減することが可能となる。さらには、複数の大きさ、形状の壁板ユニット５を製作、保管し、必要に応じて必要な大きさ、形状の壁板ユニット５を組み合わせることで、所望の大きさ、形状のダクト本体２（ダクト１）を任意に形成することが可能となる。つまり、複数の標準的な壁板ユニット５を製作、保管することで、これらの壁板ユニット５を異なる大きさ、形状のダクト１に共用することが可能となる。ここで、壁板ユニット５は単体として保管、管理できるため、積み重ねて保管することなどが可能となり、保管コストや管理コストを削減することが可能となる。   Moreover, even if the size and shape of the duct 1 are different, the same shape material can be used. That is, according to the size and shape of the duct 1, the shaped material is cut as described above, the wall plate 51 having a predetermined size and shape, the goby members 52 and 53, and the flange plates 54 and 55 having a predetermined length. Form. Then, by assembling these, the wall plate unit 5 having a predetermined size and shape, the duct body 2 and the duct 1 can be formed. As a result, it is possible to reduce the manufacturing cost, storage, management cost, etc. by sharing the shape material. Furthermore, the wall body unit 5 having a plurality of sizes and shapes is manufactured and stored, and the wall body unit 5 having a desired size and shape is combined by combining the wall plate units 5 having a necessary size and shape as necessary. (Duct 1) can be arbitrarily formed. That is, by manufacturing and storing a plurality of standard wallboard units 5, these wallboard units 5 can be shared by the ducts 1 having different sizes and shapes. Here, since the wallboard unit 5 can be stored and managed as a single unit, it can be stored in a stacked manner, and storage costs and management costs can be reduced.

For example, in this embodiment, the wall plate 51 is made of a calcium plate, but may be made of a plywood board, a gypsum board, or other heat insulating board. Moreover, although the case where the duct main body 2 is a straight square duct has been described, it is needless to say that the duct main body 2 can be applied to an L-shaped elbow or an S-curved escan.
