本発明は電話線、電線用のケーブル、パイプ等を導入す
るための、マンホール付き函体の複数口ダクトとその製
造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-opening duct with a manhole-equipped box for introducing telephone wires, cables for electric wires, pipes, etc., and a method for manufacturing the same.
マンホール付き函体の側壁に設ける複数口ダクトは１６
０，８０，１２０のごとく多数口の形で設けられている
が、工事現場の状況によってケーブルやパイプの本数や
径が異なるために、マンホール付き函体の成型時に開口
するよりも、現場でケーブル等の本数、必要性に応じて
複数口ダクトを作製する方が好都合である。The number of multiple ducts installed on the side wall of the box with manhole is 16.
0, 80, and 120, but since the number and diameter of cables and pipes vary depending on the construction site conditions, it is better to open the cables at the site rather than opening them when forming the manhole-equipped box. It is more convenient to fabricate a multi-port duct depending on the number of ducts and necessity.
しかし型枠等の資材の乏しい工事現場で函体の側壁に複
数口ダクトを作製することは不便且つ非能率なことであ
った。However, it is inconvenient and inefficient to fabricate multiple ducts on the side walls of a box at a construction site where materials such as formwork are scarce.

固化させる。To do this, as shown in FIG.
Place the enclosure frame 2 with the side a facing down, apply adhesive to the edge of the frame portion 2a, apply adhesive to the square flange edge of the duct cylinder 1, and form the square flange 1c in a grid pattern within the frame portion 2a. Place them side by side and let the adhesive harden.
このようにすると囲い枠２の端部と方形鍔群１ｃ、１ｃ
・・・・・・が面一になり、ダクト筒体１０筒体部は囲
い枠２内にあって一方向に並んで上方を向いている。In this way, the edges of the enclosure frame 2 and the square collar groups 1c, 1c
. . . are flush with each other, and the duct cylinders 10 are located within the enclosure frame 2, lined up in one direction, and facing upward.
よって第４図に示すように囲い枠２とダクト筒体１０筒
体部との間に、軽量骨材入りセメントモルタル、もしく
はモルタルのみを打込み固化させる。Therefore, as shown in FIG. 4, cement mortar containing lightweight aggregate, or only mortar, is placed between the enclosure frame 2 and the cylindrical portion of the duct cylindrical body 10 and solidified.
どの形成に際しては、額縁部２ａと方形鍔１ｃとが面一
状態を崩さないかぎり、必ずしも接着剤を用いなくても
よい。In any formation, it is not necessary to use adhesive as long as the frame portion 2a and the rectangular flange 1c are kept flush with each other.
以上のように複数日ダクト盤Ａを形成して後、第５図に
