ることを繰返し行つて垂直状に構築していた。``Conventional technology'' When constructing a concrete chimney, if you build the formwork vertically and pour concrete all at once to the desired height, the pressure of the concrete will be so great that the formwork will burst. A formwork with a relatively short height is constructed on top of the foundation, concrete is poured inside it, and after it hardens, the formwork is removed, a formwork is reassembled above it, and concrete is poured. I went over and over and built it vertically.

それらを解決しようとしたのが本発明である。``Problems to be Solved by the Invention'' When constructed as described above, it is necessary to set up the formwork, pour concrete, wait for it to harden, and then set up the formwork again, which takes a lot of time. In addition, work at high places was troublesome, expensive, and took a long time to complete. The present invention attempts to solve these problems.

管、１１は煙道となる貫孔である。"Means for Solving the Problems" The method of the present invention first consists of constructing a long and narrow box 1 whose top surface is open as a formwork, and forming a slender box 1 at the longitudinal center of the interior near both ends. A short cylindrical pipe 2 made of clay pipe or other non-combustible material is arranged at an appropriate interval in the center, and the short cylindrical pipe 2 is
It is supported by wires 4 suspended from support rods 3 installed on opposing side walls of the upper surface of the box 1.
A circular rod 6 inserted through a through hole 5 provided on one end surface of the box body 1 is inserted into the short cylindrical tube 2 and supported, and a reinforcing bar 7 is arranged around the outer periphery of the circular rod 6. It is something to keep. A rotating handle 8 is provided at the end of the circular rod 6 protruding from the box body 1. Next, hard-mixed concrete 9 is poured into the box 1 constructed in this way and put through a vibrator, and once it hardens a little, the rotary handle 8 is rotated to rotate the circular rod 6 while the box 1 is poured. The wire 4 is produced by pulling it out from the mold, allowing it to harden as it is, and then removing it from the box 1 and cutting the wire 4. At that time, the short cylindrical pipe 2 and the wire 4 buried in the concrete 9 remain as they are. In the drawing, the box 1 has a rectangular cross section, but if it were made polygonal or circular, chimney pipes having the respective cross sections would be constructed. 1
0 is a concrete chimney pipe manufactured according to the present invention, and 11 is a through hole that becomes a flue.

構成されるものである。"Function" The present invention provides that the chimney can be easily constructed by erecting the chimney pipe shown in Fig. 4 made by such a method on a foundation and fixing the lower part of the chimney pipe with concrete. It is something that will be done.
「発明の効果」
本発明は、前記のようにして製作するものであ
つて、極めて簡単に製作できるし、箱体１を長く
すれば希望する長さのものを同一時間で製作でき

貫孔１１を形成できる等の効果を奏する。"Effects of the Invention" The present invention is manufactured as described above, and is extremely easy to manufacture, and by lengthening the box 1, a desired length can be manufactured in the same amount of time. It only takes about one day to remove the mold from the box body 1, allowing for mass production in a relatively short period of time, faster production than conventional concrete chimneys, no special skills required, and the formwork is simple. Since it can be used repeatedly, it can be made at low cost, and since the circular rod 6 is pulled out while rotating, it is possible to form a straight through hole 11 without damaging the inner surface.
