Description

本発明は、壁穴3を貫通する配管2と壁穴1との間に存在する隙間3を閉塞するために、図1の如く多角形状或いは円形状の鉛板で形成したフランジ4の中央部にカッタ−や鋏を用いて中心から放射状に複数本の切り込み5を設け、所要時にフランジ4面と直角方向に前記切り込み5部分を円筒状になるようにそれぞれ折り曲げ、壁穴1を貫通する配管2の外径に合わせて円筒体7を形成し、壁穴1の片側に前記フランジ4面を取り付けるとともに前記円筒体7を壁面に対して外方側に突出させ、配管2の表面に前記円筒体7の内面を接触させて取り付け、配管2の表面に前記円筒体7を接触させた後前記円筒体7の端部位置する前記配管2の表面に鉛板8を巻き付け、前記鉛板8と前記円筒体7の表面に更に鉛板9をそれぞれに跨がるように巻き付けて隙間3を閉塞するようにした閉塞方法或いは壁穴1と配管2との間に存在する隙間3を閉塞するために、配管2の表面に鉛板10を巻き付け、鉛板10の端部を前記隙間3内に鉛板10を挿入しつつ或いは隙間3に無理やり挿入させつつ配管2の表面に巻き付け、その後前記フランジ4の円筒部7を前記鉛板10の表面に接触させた後前記円筒部7の表面に鉛板9を巻き付け、前記円筒部7と前記鉛板10の表面のそれぞれの表面に跨がるように鉛板9を巻き付けて隙間3を閉塞することにより、室内に存在する放射線発生装置又は放射性物質から発生する放射線を室外に漏れないように閉塞するか或いは室内に設置された機械装置から発生する騒音を室外に放散させないように構成した閉塞方法に関するものである。
詳しく述べれば、本発明は放射線を発生する放射線発生装置を設置した部屋又は放射性物質を貯蔵する部屋又は大きな騒音を発生する機械装置を収納した部屋に有する配管用の壁穴1等の隙間3から漏れる放射線或いは騒音を手軽にかつ速やかに閉塞することが出来る閉塞方法を提供するものであり、多角形状又は円形状の鉛の薄板で形成したフランジ4の中央部に複数本の切り込み5を中心位置から放射状に設け、前記放射状に設けた切り込み5の先端位置は壁穴1を貫通する配管2の外径寸法に合わせて成形しており、前記切り込み5はフランジ4面に対し直角方向に折り曲げて配管2の表面に密接させて円筒部7を形成するように構成している。配管2を壁穴に施工する際にフランジ4の切り込み5をフランジ4面と直角方向に折り曲げて前記配管の外径面に合わせた円筒部7を形成し、前記配管2の外径面と円筒部7の内面を密接させるとともにフランジ4面を壁面に密接させる。その後円筒部7の端部に接する配管2の表面に鉛板8を巻き付け、更に前記円筒部7の表面と前記配管2の表面に巻き付けた鉛板8の表面に別の鉛板9を両者の接触位置の表面に被せるように巻き付けて放射線漏れ或いは騒音漏れを防止するために閉塞構造を形成したものである。また以上の構成で放射線漏れ或いは騒音漏れが心配される場合は図6又は図7の如く配管2と壁穴1の隙間3内に鉛板10を挿入する場合或いは隙間3が小さくて挿入出来ない場合は壁穴1の壁面に接する配管2の表面に薄い鉛板10′を巻き付けた後壁穴内に無理やり押し込み装着するとともに前記鉛板10′の端部に鉛板10を接触させて配管2の表面に巻き付け、上記と同様の方法でフランジ4の円筒部7の内面を前記鉛板10の表面に密接させるとともに前記円筒部7及び鉛板10のそれぞれの表面に更に別の鉛板9を跨がるように巻き付けて形成することにより放射線漏れ又は騒音漏れをより確実に防止することが出来る。
なお、上記の場合は同時施工の場合を述べたが、配管2が既に施工されている場合は、図2の如くフランジ4に設けた複数の切り込み5のうちの一つを前記フランジ4の端部まで延長した切り込み6を設け、中心部に設けた切り込み5を直角方向に折り曲げて円筒部7を形成した後一つの切り込み6の両側を前後又は左右にたがいちがいに広げて配管2の外径を通過させて円筒体7を取り付け、上記同様鉛板8及び9及び10及び10′をそれぞれ巻き付けた遮蔽構造を形成すれば良い。
以上のことから本発明の施工方法は極めて容易且つ速やかに行えかつ安価に施工することが可能となる優れた利点を有するものであるが、従来工法のように壁穴1と配管2との間に存在する隙間3内にモルタル等の目地を詰め込んだ後鉛板を壁面にあてがって壁面の隙間を閉塞する等の手間のかかる閉塞工法を行う場合又は壁穴1と配管2との間に存在する隙間3を閉塞するために鉛板のみを用いて配管2に巻き付けると同時に壁面に鉛板を張りつけてその継ぎ目を熔接にて接合する施工方法或いは鉛板を配管2の表面に巻き付けた後鉛板の先端部分を配管2の表面から壁面に対し直角に立ち上げるために切り込みを入れた後折り曲げてその面を壁面にあてがうことにより閉塞処置を行う等の雑な施工方法を行う場合があるが、この雑な施工方法では鉛板の放射状に広がる空間を有する立ち上がり部分の隙間から放射線漏れ或いは騒音漏れが考えられ、確実な放射線漏れ防止及び騒音漏れ防止を行うことが出来ない等の欠点を有するものである。
In the present invention, in order to close the gap 3 existing between the pipe 2 passing through the wall hole 3 and the wall hole 1, the central portion of the flange 4 formed of a polygonal or circular lead plate as shown in FIG. A plurality of cuts 5 are provided radially from the center using cutters or scissors, and when necessary, the cuts 5 are bent in a direction perpendicular to the surface of the flange 4 so as to be cylindrical, and pipes that pass through the wall hole 1. The cylindrical body 7 is formed in accordance with the outer diameter of 2, the flange 4 surface is attached to one side of the wall hole 1, and the cylindrical body 7 is protruded outward with respect to the wall surface. The inner surface of the body 7 is contacted and attached, and after the cylindrical body 7 is brought into contact with the surface of the pipe 2, a lead plate 8 is wound around the surface of the pipe 2 positioned at the end of the cylindrical body 7. A lead plate 9 is further straddled on the surface of the cylindrical body 7. A closing method in which the gap 3 is closed by winding or the lead plate 10 is wound around the surface of the pipe 2 in order to close the gap 3 existing between the wall hole 1 and the pipe 2. Is wound around the surface of the pipe 2 while inserting the lead plate 10 into the gap 3 or by forcibly inserting the lead plate 10 into the gap 3, and then the cylindrical portion 7 of the flange 4 is brought into contact with the surface of the lead plate 10 before the cylinder. The lead plate 9 is wound around the surface of the portion 7, and the lead plate 9 is wound so as to straddle the respective surfaces of the cylindrical portion 7 and the surface of the lead plate 10, thereby closing the gap 3. The present invention relates to a blocking method configured to block radiation generated from a radiation generating device or a radioactive substance so as not to leak outside or to prevent noise generated from a mechanical device installed indoors from being diffused outside.
More specifically, the present invention is based on a gap 3 such as a wall hole 1 for piping in a room in which a radiation generator for generating radiation is installed, a room for storing radioactive materials, or a room in which a mechanical device for generating large noise is stored. Provided is a closing method capable of easily and quickly closing leaking radiation or noise, and has a plurality of incisions 5 at the center of a flange 4 formed of a thin plate of polygonal or circular lead. The radial positions of the cuts 5 are formed in accordance with the outer diameter of the pipe 2 passing through the wall hole 1, and the cuts 5 are bent in a direction perpendicular to the flange 4 surface. The cylindrical portion 7 is formed in close contact with the surface of the pipe 2. When the pipe 2 is installed in the wall hole, the notch 5 of the flange 4 is bent in a direction perpendicular to the flange 4 surface to form a cylindrical portion 7 that matches the outer diameter surface of the pipe, and the outer diameter surface of the pipe 2 and the cylinder The inner surface of the portion 7 is brought into close contact with the flange 4 surface in close contact with the wall surface. Thereafter, a lead plate 8 is wound around the surface of the pipe 2 in contact with the end of the cylindrical portion 7, and another lead plate 9 is attached to the surface of the cylindrical portion 7 and the surface of the lead plate 8 wound around the surface of the pipe 2. In order to prevent radiation leakage or noise leakage by wrapping over the surface of the contact position, a blocking structure is formed. Further, in the case where there is a concern about radiation leakage or noise leakage with the above configuration, when the lead plate 10 is inserted into the gap 3 between the pipe 2 and the wall hole 1 as shown in FIG. 6 or FIG. In this case, a thin lead plate 10 ′ is wound around the surface of the pipe 2 in contact with the wall surface of the wall hole 1, and the lead plate 10 is brought into contact with the end of the lead plate 10 ′ by forcibly pushing it into the wall hole. The inner surface of the cylindrical portion 7 of the flange 4 is brought into close contact with the surface of the lead plate 10 in the same manner as described above, and another lead plate 9 is straddled on the respective surfaces of the cylindrical portion 7 and the lead plate 10. It is possible to more reliably prevent radiation leakage or noise leakage by forming the wire so as to be wound.
In addition, although the case of simultaneous construction was described in the above case, when the pipe 2 has already been constructed, one of a plurality of cuts 5 provided in the flange 4 as shown in FIG. An incision 6 extending to the center is provided, a notch 5 provided in the center is bent in a right angle direction to form a cylindrical portion 7, and then the both sides of one notch 6 are spread back and forth or left and right alternately, and the outer diameter of the pipe 2 And the cylindrical body 7 is attached to form a shielding structure in which the lead plates 8, 9 and 10 and 10 'are respectively wound.
From the above, the construction method of the present invention has an excellent advantage that it can be carried out very easily and quickly and can be constructed at low cost. However, as in the conventional construction method, it is between the wall hole 1 and the pipe 2. When filling the joint 3 such as mortar in the gap 3 existing in the wall and applying a troublesome closing method such as applying a lead plate to the wall to close the gap in the wall, or between the wall hole 1 and the pipe 2 In order to close the gap 3 to be closed, the lead 2 is wound around the pipe 2 using only the lead plate, and at the same time, the lead plate is attached to the wall and the joint is welded by welding or the lead plate is wound around the surface of the pipe 2 There are cases in which a rough construction method such as a blockage treatment is performed by making a notch in order to raise the tip of the plate from the surface of the pipe 2 at a right angle to the wall surface and then bending and applying the surface to the wall surface. This miscellaneous construction The law is one having the disadvantages of such unthinkable radiation leakage or noise leaking from the gap between the rising portion, it is possible to perform a reliable radiation leakage prevention and noise leakage prevention with a space extending radial lead plate.

従来の工法を述べると、室内に放射線発生装置を設置した部屋又は放射性物質を保管した部屋又は騒音を発生する機械装置を設置した部屋は、鉛板等を壁面に張り付けて放射線発生装置又は放射性物質から発生する放射線漏れを防止する構造或いは騒音を防止する遮音構造を設けているのが通常である。
しかしこれらの放射線漏れ防止構造或いは騒音の遮音構造を構成していても、これらの室内から室外に出すための配管即ち水道管、電線用配管、空調用配管、排水管等の設置が必要な場合、これらの管類を室内から室外に出すために所要壁面に壁穴1を設けて前記管類をそれぞれ貫通させて設ける場合、それぞれの壁穴1部分に放射線漏れ防止又は騒音漏れ防止用の対策を更に行う必要がある。
これらの配管2を貫通させるために壁面に壁穴1を設けて前記配管2を貫通させて形成した際、前記配管2の外周面と前記壁穴1の内周面との間に生ずる隙間3から放射線発生装置又は放射性物質から発生する放射線が漏洩して危険であり、また機械装置から発生する騒音が室内から室外に漏れると工場内で作業している作業員或いは工場周辺の住民との間で問題を生ずる恐れがある。
そこで、これらの問題を解決するために、配管2の表面と壁穴1の内周面との間に生じた隙間3にモルタル等を詰め込んで隙間3を無くした後配管2の外径部分に合わせて円形に切り取った鉛板を壁面に張付けて放射線及び騒音を遮蔽する施工方法及び配管2の表面と壁面とにそれぞれ鉛板をあてがい両者の継目を熔接して固定する等施工手間のかかる煩わしい工法が行われる場合或いは前記のような手間のかかる工法を省略するために配管2の表面に巻き付ける鉛板の先端部分に複数の切り込みを入れて配管2の表面に対して直角方向に立ち上げ、前記立ち上げ部分を壁面にあてがって固定し遮蔽するように構成した施工方法が行われている。この施工方法の場合前者は施工手間が掛かりすぎる欠点を有し、後者は施工方法は極めて簡単容易であるが鉛板の立ち上がり部分において放射状に空間を生ずるためそれらの空間から放射線或いは騒音の漏れを生じることとなり室内から放散される放射線或いは騒音等を確実に防止することは出来ない欠点を有するものである。
In the conventional construction method, the room where the radiation generator is installed, the room where the radioactive material is stored, or the room where the mechanical device that generates noise is installed is attached to the wall with a lead plate etc. It is usual to provide a structure for preventing radiation leakage generated from the sound or a sound insulation structure for preventing noise.
However, even if these radiation leak prevention structures or noise insulation structures are configured, it is necessary to install pipes for exiting the room from outside, that is, water pipes, electric pipes, air conditioning pipes, drain pipes, etc. In order to bring out these pipes from the room to the outside, when a wall hole 1 is provided on a required wall surface and the pipes are respectively penetrated, a measure for preventing radiation leakage or noise leakage at each wall hole 1 portion. It is necessary to perform further.
When a wall hole 1 is provided on the wall surface to penetrate these pipes 2 and the pipe 2 is formed through the gap 2, a gap 3 formed between the outer peripheral surface of the pipe 2 and the inner peripheral surface of the wall hole 1. If the radiation generated from the radiation generator or radioactive material leaks from the air, it is dangerous, and if the noise generated from the mechanical device leaks from the room to the outside, it is between the workers working in the factory or the residents around the factory. Can cause problems.
Therefore, in order to solve these problems, the gap 3 formed between the surface of the pipe 2 and the inner peripheral surface of the wall hole 1 is filled with mortar or the like, and the gap 3 is eliminated. A construction method that shields radiation and noise by attaching a lead plate cut out in a circular shape together to the wall surface, and a troublesome work such as attaching the lead plate to the surface and wall surface of the pipe 2 and welding and fixing the joints of both. When a construction method is performed or in order to omit the time-consuming construction method as described above, a plurality of cuts are made in the leading end portion of the lead plate wound around the surface of the pipe 2 and it is raised in a direction perpendicular to the surface of the pipe 2. There is a construction method in which the rising portion is applied to a wall surface to be fixed and shielded. In the case of this construction method, the former has the disadvantage that it takes too much work, and the latter is very simple and easy, but since a space is formed radially at the rising part of the lead plate, leakage of radiation or noise from those spaces is caused. It has a drawback that it is impossible to reliably prevent radiation or noise that is generated and diffused from the room.

本発明は上述した従来技術の問題点を改良し、壁穴1と前記壁穴1を貫通する配管2の間に存在する隙間3からの放射線或いは騒音の漏れを防止するために、壁面に密接させるフランジ4の中心部に設けた切り込み5を直角方向に折り曲げて円筒体7を形成し、壁穴1を貫通した配管2の表面に密接させる構造の前記円筒体7と配管2の表面に巻き付ける鉛板8及び9又は前記円筒体7及び円筒体7と配管2の間に存在させる鉛板10及び前記円筒体7および鉛板10の両表面を跨ぐように巻き付ける鉛板9を用いて壁穴1と配管2の間に存在する隙間3を閉塞し、室内から放散される放射線又は騒音の室外漏れを確実に防止することが出来る閉塞方法を提供するものである。  The present invention improves the above-mentioned problems of the prior art and closes the wall surface in order to prevent leakage of radiation or noise from the gap 3 existing between the wall hole 1 and the pipe 2 passing through the wall hole 1. A notch 5 provided at the center of the flange 4 to be bent is bent in a right angle direction to form a cylindrical body 7, and is wound around the surface of the cylindrical body 7 and the pipe 2 having a structure in close contact with the surface of the pipe 2 penetrating the wall hole 1. Wall holes using lead plates 8 and 9, or the cylindrical body 7 and the lead plate 10 that exists between the cylindrical body 7 and the pipe 2 and the lead plate 9 that is wound so as to straddle both surfaces of the cylindrical body 7 and the lead plate 10. The present invention provides a closing method in which a gap 3 existing between 1 and a pipe 2 is closed and radiation or noise radiated from the room can be reliably prevented from leaking outside the room.

本発明の、壁穴1を貫通する配管2と前記壁穴1との間に存在する隙間3を閉塞する閉塞方法について図1から図7に示す実施例に基づき具体的に説明すると、室内に設置された放射線発生装置又は室内に貯蔵された放射性物質から放散される放射線或いは室内に設置された機械装置から発生する大きな騒音が配管2を貫通させた壁穴1と前記配管2との間に存在する隙間から室外に漏れるのを防止するために行うものである。
先ず図1に示すフランジ4について述べると、前記フランジ4は薄い鉛板を用いて多角形状又は円形状に形成し、前記フランジ4の中心付近には、カッタ−又は鋏を用いて複数本の切り込み5をその中心点から放射状に形成する。なお鋏を用いて切り込み5を作成する場合は、その中心付近に小さい丸穴を前もって設けていればその切り込み加工が容易に行える。
前記放射状に設けた切り込みの中心から先端部位置迄の寸法を前記配管2の直径に合わせて形成する。この切り込み5をフランジ4の面に対し直角方向に折り曲げて前記配管2の外径に合わせた円筒体7を形成し、前記円筒体7の内面を前記配管2の表面に密に接触させるように構成している。この実施例の場合は、配管2を前記円筒体7に挿入して配管2の表面と円筒体7の内面を密に接触させる場合に用いられるものである。
既に配管2が壁穴1に貫通した状態で設置されている場合は、図2に示すフランジ4を用いるものであり、このフランジ4は図1に示すフランジ4を利用し、中心付近に設けている複数の切り込み5の中の一本の切り込み6をフランジ4の端部まで延長して設けたものである。この実施例の場合は、前記同様切り込み5部分を直角方向に折り曲げて円筒体7を形成した後前記一本の切り込み6の両側を前後又は左右に互い違いに広げて配管2の外径を通過させた後円筒体7の内面を配管2の表面に密に接触させ、その後フランジ4面を壁穴1の周囲の壁面に取り付けるように構成しているものである。
前記円筒体7は図3及び図4に示すとおり、切り込み5をフランジ4面に対し直角方向に折り曲げて円筒体7を形成した場合前記切り込み5の面は折り曲げられた際三角形に形成されるので円筒体7の先端部分は鋸状に形成されているため三角形の鋸状空間を生ずる。そこで前記三角形の空間から放射線或いは騒音が漏洩するのを防止するために円筒体7の表面と鉛板8の接続部表面に跨がるように鉛板9を巻き付けている。
なお、配管2の表面に取り付けた前記円筒体7の表面に生ずる三角形の空間には、前記空間に合わせた鉛板をあてがって張りつけ、その後その表面に鉛板9を巻き付ける構造にすれば閉塞効果が更に向上する。
以上のように円筒体7を形成したフランジ4を用いて、前記円筒体7を配管2の表面に直接接触させるか或いは配管2の表面に鉛板10を巻き付けるとともに壁穴1と配管2の間に存在する隙間3部分にも前記鉛板10又は10′を存在させて前記隙間3部分を閉塞するように形成した後前記円筒体7を接触させるように構成している。
壁穴1を貫通している配管2の間に存在する隙間3から漏れる放射線或いは騒音をより確実に防止するために、配管2の表面に密に接触させた前記フランジ4の円筒体7の先端部分に鉛板8を連接させて巻き付けた後前記円筒体の表面と鉛板8との表面に両者を跨がるように鉛板9を巻き付ける虹を行う場合と前記配管2の表面に直接鉛板10を巻き付ける際に前記壁穴1と配管2の間に存在する隙間3部分に前記鉛板10又は10′を存在させて前記隙間3を閉塞するように形成し、壁穴1の一方の壁面にフランジ4を取り付け、前記フランジ4の中心部に設けた円筒体7の内面と配管2の表面に巻き付けた鉛板10の表面とを密接に接触させた後前記円筒体7と鉛板10の表面に更に別の鉛板9を巻き付け、前記鉛板9は鉛板10と円筒体7のそれぞれの表面に跨がるように巻き付ける施工を行う方法がある。
前記フランジ4を壁面に取り付ける場合及び配管2の表面に密接させる円筒体7の内面更には鉛板8及び9及び10の巻き付け面に接着材を付着させると作業性が飛躍的に向上する利点を有する。
