この連結アンカー１６の施工用穴９及び吊り上げ運搬用の吊り上げナット穴１０の形成個数については何ら制限されるものではなく、それぞれ２個以上の複数個設けても構わないものである。
図２乃至図４に示す具体例では、連結アンカー１６の施工用穴９は底壁部６の長手方向中央部に１個、また吊り上げナット穴１０はやはり中央部に１個の合計２個形成してある。 The numbers of the construction holes 9 and the lifting nut holes 10 for lifting and transporting the connecting anchor 16 are not limited at all, and two or more of them may be provided.
In the specific examples shown in FIGS. 2 to 4, two construction holes 9 for the connecting anchor 16 are formed in the center portion in the longitudinal direction of the bottom wall portion 6, and two lifting nut holes 10 are also formed in the central portion. It is.

ところで、断面略U字状をなすケーブルダクト本体部品５における両側壁７、７の上端部上面は略水平に形成され、該両側壁７、７上端部上面に前記ダクト蓋８が密着して載置可能な様に蓋載置部１１が形成される。 By the way, the upper surfaces of the upper ends of the side walls 7 and 7 of the cable duct body part 5 having a substantially U-shaped cross section are formed substantially horizontally, and the duct lid 8 is mounted in close contact with the upper surfaces of the both side walls 7 and 7. The lid mounting part 11 is formed so that it can be placed.

ここで、ケーブルダクト本体部品５における一方側側壁７の上端部は、当該一方側側壁７の外側面から、上方向に向かい、外側に上り勾配状の傾斜面を有して延び、該傾斜面の上端部からさらに前記上方向に垂直壁を構成し、その部分が厚みを有する膨出部として構成されてなり、前記側壁７の上端部の厚み幅が長くなるように形成されている。   Here, the upper end portion of the one side wall 7 in the cable duct body part 5 extends upward from the outer surface of the one side wall 7 and has an upward inclined surface on the outer side. Further, a vertical wall is formed in the upward direction from the upper end portion of the upper portion, and the portion is formed as a bulging portion having a thickness, and the thickness width of the upper end portion of the side wall 7 is increased.

このように側壁７の上端面の幅に厚みを有して構成することにより蓋載置部１１に載置されるダクト蓋８を密着させて、安定的に支持できる。   As described above, the width of the upper end surface of the side wall 7 is configured to have a thickness so that the duct lid 8 placed on the lid placing portion 11 can be brought into close contact with and stably supported.

次に本発明の施工状態につき説明する。
線路部の脇には高欄４が設けられている。該高欄４の一部をダクトの一方側側壁７に兼用する。
ついで、前記高欄４側の側壁７との対向面側には所定の間隔をおいて断面略Ｕ字状をなすあらかじめ製造されたダクト本体部品５を前記所定間隔の長さを変更自在にして敷設する。 Next, the construction state of the present invention will be described.
A rail 4 is provided on the side of the track portion. A part of the rail 4 is also used as one side wall 7 of the duct.
Next, a pre-manufactured duct body part 5 having a substantially U-shaped cross section with a predetermined interval is laid on the side facing the side wall 7 on the rail 4 side so that the length of the predetermined interval can be changed. To do.

そして、前記蓋載置部１１が形成された高欄４側の側壁７及び前記ダクト本体部品５の一方側側壁部７とにより略凹状をなす第１ダクト本体部１３が形成される。
この第１ダクト本体部１３の底面幅は変更自在であり、収納するケーブル２の数量やその他の要因により、幅の長さは決定される。 The first duct main body 13 having a substantially concave shape is formed by the side wall 7 on the side of the rail 4 where the lid mounting portion 11 is formed and the one side wall 7 of the duct main body part 5.
The bottom face width of the first duct main body 13 can be changed, and the length of the width is determined depending on the number of cables 2 to be accommodated and other factors.

この第１ダクト本体部１３の底面幅が決定した後、ケーブルダクト本体部品５の施工用穴９を連結アンカー１６に遊嵌させつつ位置決め微調整し、固定用モルタル１４を打設する。この固定用モルタル１４はケーブルダクト本体部品５の底面下側および第１ダクト本体部１３の底面部に打設される。   After the bottom width of the first duct main body 13 is determined, positioning fine adjustment is performed while loosely fitting the construction hole 9 of the cable duct main body part 5 to the connecting anchor 16, and the fixing mortar 14 is driven. The fixing mortar 14 is placed on the lower side of the bottom surface of the cable duct main body part 5 and the bottom surface portion of the first duct main body portion 13.

そして、前記ダクト本体部品５の一方側側壁７の上端部には前記高欄４側のダクト側壁に設けられた蓋係止部１１と略同等の高さ位置に蓋載置部１２が設けられる。   And the lid mounting part 12 is provided in the upper end part of the one side wall 7 of the said duct main-body part 5 in the height position substantially equivalent to the lid latching | locking part 11 provided in the duct side wall of the said rail 4 side.

そして、前記双方の蓋係止部１１及び蓋載置部１２間には、あらかじめ製造されたダクト蓋８が密着して載置される。 A duct lid 8 manufactured in advance is placed in close contact between the two lid engaging portions 11 and the lid placing portion 12.

さらに、前記ダクト本体部品５の一方側側壁７と他方側側壁７間には第２ダクト本体部１７があらかじめ形成さてなると共に、双方の側壁７，７上端部には各々蓋載置部１２、１２が設けられてダクト蓋８が密着して載置されるものとなる。 Further, a second duct main body portion 17 is formed in advance between the one side wall 7 and the other side wall 7 of the duct main body component 5, and a lid mounting portion 12 is provided at the upper end portions of both side walls 7, 7, respectively. 12 is provided and the duct lid 8 is placed in close contact.

なお、ダクト本体部品５の他方側側壁７上端部には、コ字状に切り欠かれた蓋係止部１１を形成してもよく、この場合、高欄４側の蓋係止部１１とこのダクト本体部品５側の蓋係止部１１にはダクト蓋８が嵌合して載置されるものとなる。 The upper end of the other side wall 7 of the duct body part 5 may be formed with a lid locking part 11 cut out in a U-shape. In this case, the lid locking part 11 on the rail 4 side and this The duct lid 8 is fitted and placed on the lid locking portion 11 on the duct body part 5 side.

なお、高欄４の側壁７に蓋係止部１１を形成する具体例につき説明する。
線路などの前記高欄４側壁７の内側において、前記蓋係止部１１があらかじめ設けられていることもあるが、このようなダクト蓋８載置用の前記蓋係止部１１があらかじめ設けられていないときは、施工現場において新たに前記高欄４側の側壁７内側にダクト蓋載置用の前記蓋係止部１１を形成する必要がある。 In addition, the specific example which forms the cover latching | locking part 11 in the side wall 7 of the rail 4 is demonstrated.
The lid locking portion 11 may be provided in advance on the inside of the rail 4 side wall 7 such as a track, but the lid locking portion 11 for placing the duct lid 8 is provided in advance. If not, it is necessary to newly form the lid engaging portion 11 for placing the duct lid inside the side wall 7 on the railing 4 side at the construction site.

しかし、この形成作業は決して困難なものではなく、例えば長尺の角棒状部材を線路などの高欄４側壁７の内側に水平方向へ延出させて取り付ければよいのである。   However, this forming operation is never difficult. For example, a long square bar-like member may be attached to the inner side of the rail 4 side wall 7 such as a track so as to extend horizontally.
