【考案の詳細な説明】
本考案はボイラーと温風暖房機等の間を接続する被覆鋼
管の曲げ加工用のインサーターに係わり曲げ作業を容易
に、しかも手早くすることを目的とする。[Detailed Description of the Invention] The present invention relates to an inserter for bending coated steel pipes connecting between a boiler and a hot-air heater, etc., and aims to make the bending work easier and faster.
一般に、ボイラー等の熱源と、温風暖房機等のような放
熱機とを接続する被覆鋼管は、その施工の際において、
多くの曲げ部分が必要となる。Generally, when installing coated steel pipes that connect a heat source such as a boiler and a radiator such as a hot air heater,
Many bends are required.
従来、この曲げ部分の現地作業は、被覆鋼管の曲げたい
所の曲げ部分近辺に、ポリエチレン製の治具であるイン
サーターを挿入し、被覆鋼管とインサータを共に曲げて
曲げ部分を構威し、その後インサーターを抜き取り、鋼
管の座屈を防止している。Conventionally, the on-site work for this bending was done by inserting an inserter, which is a polyethylene jig, near the bending point of the coated steel pipe and bending the coated steel pipe and inserter together. The inserter is then removed to prevent the steel pipe from buckling.
しかしながら、前記ポリエチレン製のインサーターは、
被覆銅管内壁にほぼ嵌合状態で挿入されるから、被覆導
管内壁と、インサーター外周とが、部分的に密着し、そ
の摩擦抵抗によってインサーターの抜き取り作業が非常
に困難である。However, the polyethylene inserter
Since the inserter is inserted into the inner wall of the coated copper pipe in a substantially fitted state, the inner wall of the coated pipe and the outer periphery of the inserter are partially in close contact with each other, and the frictional resistance makes it extremely difficult to remove the inserter.
本考案は上記従来の難点を解消するもので、以下本考案
をその一実施例を示す図面を参考に説明する。The present invention solves the above-mentioned conventional problems, and will be described below with reference to the drawings showing one embodiment thereof.
１は温風暖房機、２はボイラー（図示せず）との接続を

で、このインサーター３はポリエチレン製で弾力性を有
し、ある硬度を保有している。1 is a warm air heater, 2 is a coated copper pipe for connection to a boiler (not shown), and 3 is an inserter inserted into the coated copper pipe 2. This inserter 3 is made of polyethylene and has elasticity. , possesses a certain hardness.
４はローレット部、５はローレット部４に所定間隔で設
けられる区間溝で、区間溝５は５００ｍｍ間隔で、Ａ−
Ｂ−Ｃ−・・・・・・・・・と設けられ、定規として使
用するものである。4 is a knurling part, 5 is a section groove provided at a predetermined interval in the knurling part 4, and the section grooves 5 are arranged at intervals of 500 mm, and A-
It is provided as B-C-... and is used as a ruler.
６は５００ ｍｍ、 １０００ ｍｍ。１５００ ｍｍ
・・・・・・と刻まれる刻印の寸法表示である。6 is 500 mm, 1000 mm. 1500mm
This is the dimensions of the engraving that says ``...''.
７はインサーター３の一端に設けられた取手で、インサ
ーター３を被覆銅管２に挿入し、曲げ部分を作った後に
引き抜く時の取手である。Reference numeral 7 denotes a handle provided at one end of the inserter 3, which is used to insert the inserter 3 into the coated copper tube 2 and pull it out after making a bent portion.
尚、上記実施例においては被覆銅管２は曲部８．９．１
０．１１゜１２、１３と直管部１４．１５．１６．１７
．１８．１９．２０からなる。In the above embodiment, the coated copper pipe 2 has a bent portion 8.9.1.
0.11゜12, 13 and straight pipe section 14.15.16.17
．． Consists of 18.19.20.
上記構成において、被覆銅管２を、例えば図のように曲
げ部分を必要とする時は、被覆銅管２が直管時において
、ローレット部４を設けたインサーター３を入口２１よ
り温風暖房機１のほぼ近くまで挿入する。In the above configuration, when the coated copper pipe 2 requires a bent portion as shown in the figure, for example, when the coated copper pipe 2 is a straight pipe, the inserter 3 provided with the knurled portion 4 is heated with warm air from the inlet 21. Insert it almost until it is close to machine 1.
そして、一段階として、曲部８を作り取手７を握って直
管部１５の中央部分まで引き抜き、次に曲部９を作り、
更に直管部１６の中央部分まで引き抜き、更に曲部１０
を作り直管部１７の中央部分まで引き抜き、更に曲部１
１を作り、直管部１８の中央部分まで引き抜き、更に曲
部１２を作り、直管部１９の中央部分まで引き抜き、更
に曲部１３を作り完全に引き抜いてしまうのである。Then, in one step, a bent part 8 is made, the handle 7 is grasped and the straight pipe part 15 is pulled out to the center part, and then a bent part 9 is made,
Further, the straight pipe part 16 is pulled out to the center part, and then the bent part 10 is pulled out.
, and then pull it out to the center of the straight pipe section 17, and then extend the curved section 1.
1, then pull it out to the center of the straight tube section 18, then make the curved section 12, pull it out to the center of the straight tube section 19, and then make the curved section 13 and pull it out completely.
この時、それぞれの直管部分までインサーター３を引き
抜くが、この時、目盛を５００ ｍｍ間隔で設けている
から、大体の見当が判読できるものである。At this time, the inserter 3 is pulled out to each straight pipe section, and since the scales are provided at 500 mm intervals, the approximate register can be read.
本考案によれば上記実施例から明らかなように、本考案
の被覆鋼管の曲げ加工用インサーターはインサーターに
ローレットを設けると共に、寸法表示をしているので、
曲部を作って引き抜く時も、被覆鋼管と密着することな
く、ローレットの山部分に接触しているだけであるから
、摩擦抵抗が軽減され非常に抜は易く強力な力を必要と
せず、現地における曲作業が容易で、短時間に完成でき
るなどの効果効果を奏するものである。According to the present invention, as is clear from the above embodiments, the inserter for bending coated steel pipes of the present invention is provided with a knurling on the inserter and has dimensions indicated.
Even when making a bend and pulling it out, it does not come into close contact with the coated steel pipe, but only contacts the ridges of the knurling, so the frictional resistance is reduced, making it extremely easy to pull out and does not require strong force. This has the advantage that the music work is easy and can be completed in a short time.
