characterized by comprising

当該空調用分岐チャンバーによれば、基端部を空調機に支持させることで、空調機から片持ち状に突出された状態となる。該空調用分岐チャンバーの先端部を１本の吊材で支持させる。チャンバー本体の先端側部分の荷重は、補強部材及び吊金具を介して１本の吊材に伝達される。チャンバー本体の先端側部分は幅が小さくなっているため、１本の吊材だけで吊支持するものであっても、安定的に支持できる。必要な吊材の数が１本だけで済むために、吊支持に要する施工時間が、複数本の吊材を用いる必要がある場合の数分の１になる。発泡樹脂を主体とするチャンバー本体は、補強部材によって補強される。 According to the air-conditioning branch chamber, the base end portion is supported by the air conditioner so that the branch chamber protrudes from the air conditioner in a cantilever manner. The tip of the air-conditioning branch chamber is supported by one hanger. The load of the tip side portion of the chamber main body is transmitted to one suspension member via the reinforcing member and the suspension fitting. Since the width of the tip side portion of the chamber body is small, even if it is suspended and supported by only one suspending member, it can be stably supported. Since only one hanging member is required, the construction time required for hanging support is reduced to a fraction of the time required for using a plurality of hanging members. A chamber main body mainly made of foamed resin is reinforced by a reinforcing member.

前記補強部材が、前記チャンバー本体の上面に被さる上帯板部と、前記チャンバー本体の下面に被さる下帯板部と、前記チャンバー本体の先端面に被さる先端帯板部を有し、前記上帯板部と前記下帯板部とが前記先端帯板部を介して連なっており、前記基端部において前記上帯板部及び下帯板部が前記接続口部材と接合されていることが好ましい。
これによって、接続口部材と補強部材とによって、チャンバー本体を一周するように囲んで保持できる。補強部材の基端部は、接続口部材を介して空調機に連結されて支持され、かつ補強部材の先端部は、吊金具を介して吊材に連結されて支持される。
前記補強部材の幅方向の両縁部には、前記チャンバー本体の外面から突出する縁壁が形成されていることが好ましい。 The reinforcing member has an upper band plate portion covering the upper surface of the chamber main body, a lower band plate portion covering the lower surface of the chamber main body, and a tip band plate portion covering the front end surface of the chamber main body. It is preferable that the plate portion and the lower band plate portion are connected via the tip band plate portion, and that the upper band plate portion and the lower band plate portion are joined to the connection port member at the base end portion. .
As a result, the connection port member and the reinforcing member can surround and hold the chamber body so as to encircle it. The base end portion of the reinforcing member is connected to and supported by the air conditioner via the connection port member, and the distal end portion of the reinforcing member is connected to and supported by the lifting member via the lifting fitting.
It is preferable that edge walls protruding from the outer surface of the chamber main body are formed at both edges of the reinforcing member in the width direction.

本発明によれば、空調用分岐チャンバーの設置施工を簡易に行うことができる。 ADVANTAGE OF THE INVENTION According to this invention, installation construction of the branch chamber for air conditioning can be performed simply.

チャンバー本体１０の基端部において、補強部材３０の両端部が接続口部材２０と接合されている。すなわち、上帯板部３１の端部が、チャンバー接続筒部２１の上板部２１ａとビス止めされている。下帯板部３２の端部が、チャンバー接続筒部２１の底板部２１ｂとビス止めされている。これによって、接続口部材２０と補強部材３０とが、互いに協働して、チャンバー本体１０を一周するように囲んで保持している。 Both ends of the reinforcement member 30 are joined to the connection port member 20 at the base end of the chamber body 10 . That is, the end portion of the upper strip portion 31 is screwed to the upper plate portion 21a of the chamber connecting cylinder portion 21 . An end portion of the lower band plate portion 32 is screwed to the bottom plate portion 21b of the chamber connection cylindrical portion 21 . Thereby, the connection port member 20 and the reinforcing member 30 cooperate with each other to surround and hold the chamber body 10 so as to encircle it.

先端帯板部３３（先端部における補強部材）に吊金具４０が設けられている。吊金具４０は、Ｌ字のアングル材によって構成されている。吊金具４０材質は、鋼、鉄、アルミなどの金属であり、例えば亜鉛めっき鋼板が用いられているが、これに限られるものではない。 A hanger 40 is provided on the tip band plate portion 33 (reinforcing member at the tip). The suspension fitting 40 is configured by an L-shaped angle member. The material of the hanger 40 is a metal such as steel, iron, or aluminum. For example, a galvanized steel sheet is used, but the material is not limited to this.

図４に示すように、吊金具４０は、固定部４１と、連結部４２を含む。固定部４１及び連結部４２は、互いに直交している。固定部４１が、先端帯板部３３に溶接やビス止めによって固定されている。連結部４２は、先端帯板部３３から先端側へ突出されている。連結部４２には、挿通孔４３が形成されている。挿通孔４３は、チャンバー本体１０の幅方向に長い長穴になっている。 As shown in FIG. 4 , the sling fitting 40 includes a fixing portion 41 and a connecting portion 42 . The fixed portion 41 and the connecting portion 42 are orthogonal to each other. A fixed portion 41 is fixed to the tip band plate portion 33 by welding or screwing. The connecting portion 42 protrudes from the tip band plate portion 33 to the tip side. An insertion hole 43 is formed in the connecting portion 42 . The insertion hole 43 is an elongated hole elongated in the width direction of the chamber body 10 .

図２に示すように、天井６から１本の吊材５が垂下されている。吊材５は例えば寸切ボルトなどの棒材によって構成されている。吊材５の下端部が、挿通孔４３に挿し入れられ、ナット５ｂによって連結部４２と接続されている。１本の吊材５によって、空調用分岐チャンバー３の先端部が吊支持されている。チャンバー本体１０の先端側部分の荷重は、補強部材３０及び吊金具４０を介して、１本の吊材５によって受けている。 As shown in FIG. 2, one hanger 5 hangs down from the ceiling 6 . The suspending member 5 is made of a rod material such as a cross-cut bolt. A lower end portion of the hanging member 5 is inserted into the insertion hole 43 and connected to the connecting portion 42 by the nut 5b. A single suspension member 5 suspends and supports the tip of the air-conditioning branch chamber 3 . The load of the tip side portion of the chamber main body 10 is received by one hanging member 5 via the reinforcing member 30 and the hanging fitting 40 .

空調用分岐チャンバー３を設置する際は、該空調用分岐チャンバー３の接続口部材２０を空調機２の送出口２ｃに嵌め込むことで、空調用分岐チャンバー３の基端部を空調機２に支持させる。これによって、空調用分岐チャンバー３が、空調機２から片持ち状に突出された状態となる。
続いて、天井６から垂下させた１本の吊材５の下端部を吊金具４０の挿通孔４３に通し、吊材５と吊金具４０とを連結する。挿通孔４３が長穴であるために、吊材５と吊金具４０との位置ずれを吸収できる。これによって、空調用分岐チャンバー３の先端部を１本の吊材５で吊支持させる。空調用分岐チャンバー３は、吊支持される先端部へ向かって幅が小さくなっているため、１本の吊材５だけで吊支持するものであっても、安定的に支持できる。 When installing the air-conditioning branch chamber 3, the base end of the air-conditioning branch chamber 3 is attached to the air conditioner 2 by fitting the connection port member 20 of the air-conditioning branch chamber 3 into the delivery port 2c of the air conditioner 2. support. As a result, the air-conditioning branch chamber 3 is in a cantilevered state protruding from the air conditioner 2 .
Subsequently, the lower end of one hanging member 5 suspended from the ceiling 6 is passed through the insertion hole 43 of the hanging fitting 40, and the hanging member 5 and the hanging fitting 40 are connected. Since the insertion hole 43 is an elongated hole, it is possible to absorb positional deviation between the suspension member 5 and the suspension fitting 40 . As a result, the end portion of the air-conditioning branch chamber 3 is suspended by one suspension member 5 . Since the width of the air-conditioning branch chamber 3 becomes smaller toward the end portion where it is hung and supported, even if it is hung and supported by only one hanging member 5, it can be stably supported.

このようにして、空調用分岐チャンバー３の設置施工を簡易に行うことができる。１つの空調用分岐チャンバー３あたりの必要な吊材５の数が１本だけで済む。したがって、吊支持に要する施工時間が、複数本の吊材を用いる必要がある場合の数分の１になる。 In this way, installation work of the branch chamber 3 for air conditioning can be easily performed. Only one hanging member 5 is required for one branch chamber 3 for air conditioning. Therefore, the construction time required for hanging support is reduced to a fraction of the time required to use a plurality of hanging members.

空調用分岐チャンバー３によれば、発泡樹脂断熱材からなるチャンバー本体１０によって断熱性を確保できる。
空調機２からの温調空気は、送出口２ｃから空調用分岐チャンバー３内に導入され、複数のダクト４に分流される。空調用分岐チャンバー３の内部流路が先端へ向かって狭くなることで、温調空気を複数のダクト４へ出来るだけ均等に分流させることができる。 According to the air-conditioning branch chamber 3, heat insulation can be ensured by the chamber main body 10 made of a foamed resin heat insulating material.
The temperature-controlled air from the air conditioner 2 is introduced into the branch chamber 3 for air conditioning from the delivery port 2 c and is divided into a plurality of ducts 4 . By narrowing the internal flow path of the air-conditioning branch chamber 3 toward the tip, the temperature-controlled air can be divided into the plurality of ducts 4 as evenly as possible.
