Description

本発明は、ソベント継手内の塗装方法に関する。 The present invention relates to a coating method inside a sovent joint.

マンション等の集合住宅等の排水設備は、その材質が金属を用いている場合、長期の使用によりその内部が腐食する等の問題が発生しやすい。そのため、定期的な点検と必要に応じた補修(再生)が必要となる。例えばこの技術としては、下記特許文献1に記載がある。 When drainage facilities such as condominiums and other condominiums are made of metal, problems such as corrosion of the inside of the drainage facilities are likely to occur due to long-term use. Therefore, regular inspection and repair (regeneration) as necessary are required. For example, this technique is described in Patent Document 1 below.

特開2019-44856号公報Japanese Unexamined Patent Publication No. 2019-44856

一方で、マンション等の集合住宅等における排水設備においては、鉛直方向に延びる排水管と水平方向に延びる排水管を接合するが、この接合部分に、効率的に排水を行うための空間を備えたソベント継手が用いられることが多い。 On the other hand, in drainage facilities such as condominiums, drainage pipes extending in the vertical direction and drainage pipes extending in the horizontal direction are joined, and a space for efficient drainage is provided at this joint. Sovent joints are often used.

このソベント継手は、空間において鉛直方向に延びる排水管により形成される排水の流れと水平方向に延びる排水管により形成される排水の流れを仕切るためのプレートを有する複雑な構造を備えており、この内部の再生は容易ではない。特に、ソベント継手の天板部分は塗装が難しいといった課題がある。 This sovent joint has a complex structure with a plate for partitioning the flow of drainage formed by vertically extending drainage pipes and the flow of drainage formed by horizontally extending drainage pipes in space. Internal regeneration is not easy. In particular, there is a problem that it is difficult to paint the top plate of the sovent joint.

そこで、本発明は、上記課題に鑑み、天板部分に対しても十分な効果を発揮できるソベント継手内の塗装方法を提供することを目的とする。 Therefore, in view of the above problems, it is an object of the present invention to provide a coating method in a sovent joint that can exert a sufficient effect on a top plate portion.

上記課題を解決する本発明の一観点に係るソベント継手内の塗装方法は、鉛直方向上側から延伸する第一の配管が接続される天板部材と、天板部材の周囲縁を覆うよう天板部材に接続されつつその断面が鉛直方向上側から下側に行くに従い小さくなる部分を有し、鉛直方向略垂直な方向から第二の配管に接続されているとともに、鉛直方向下側において第三の配管にも接続される周壁部材と、周壁部材内において天板部材に接続され、鉛直方向上側から下側に延伸するとともに孔が形成されたプレートと、を備えるソベント継手内の塗装方法であって、第二の配管から第三の配管への空流を形成するステップ、第二の配管からソベント継手内に膨張部材を挿入し、プレートとソベント継手内の周壁部材との間に、膨張部材を膨張させて配置し、第二の配管から第三の配管への空流を阻害するステップ、第二の配管からソベント継手内の天板部材を塗装するステップ、を有するものである。 The method for painting the inside of the sovent joint according to one aspect of the present invention for solving the above problems is to cover the top plate member to which the first pipe extending from the upper side in the vertical direction is connected and the peripheral edge of the top plate member. It has a portion that becomes smaller as its cross section goes from the upper side to the lower side in the vertical direction while being connected to the member, and is connected to the second pipe from a direction substantially perpendicular to the vertical direction, and is connected to the second pipe in the lower side in the vertical direction. A method of painting inside a sovent joint including a peripheral wall member that is also connected to a pipe and a plate that is connected to the top plate member in the peripheral wall member and extends from the upper side to the lower side in the vertical direction and has a hole formed therein. , The step of forming an air flow from the second pipe to the third pipe, insert the expansion member from the second pipe into the sovent joint, and insert the expansion member between the plate and the peripheral wall member in the sovent joint. It has a step of inflating and arranging and obstructing the air flow from the second pipe to the third pipe, and a step of painting the top plate member in the sovent joint from the second pipe.

また、本観点において、限定されるわけでは無いが、第二の配管から第三の配管への空流を阻害するステップは、プレートの孔から第二の配管から第三の配管への迂回空流を形成することが好ましい。 Further, from this viewpoint, although not limited, the step of obstructing the air flow from the second pipe to the third pipe is a detour air from the hole of the plate to the second pipe to the third pipe. It is preferable to form a stream.

また、本観点において、限定されるわけでは無いが、第二の配管からソベント継手内の天板部材を塗装するステップは、第二の配管から第三の配管への迂回空流に沿って流体塗料を運びつつ天板部材の下面を塗装することが好ましい。 Further, from this point of view, the step of painting the top plate member in the sovent joint from the second pipe is fluid along the detour airflow from the second pipe to the third pipe. It is preferable to paint the lower surface of the top plate member while carrying the paint.

また、本観点において、限定されるわけでは無いが、第二の配管から第三の配管への空流を形成するステップの後、第二の配管から第三の配管への空流を阻害するステップの前に、ソベント継手内を研磨するステップ、を備えることが好ましい。 Also, from this point of view, after the step of forming the airflow from the second pipe to the third pipe, the airflow from the second pipe to the third pipe is hindered, though not limited to. Prior to the step, it is preferable to include a step of polishing the inside of the sovent joint.

以上、本発明によって、天板部分に対しても十分な効果を発揮できるソベント継手内の塗装方法を提供することができる。 As described above, according to the present invention, it is possible to provide a coating method in a sovent joint that can sufficiently exert a sufficient effect on the top plate portion.

以下、本発明の実施形態について図面を用いて詳細に説明する。ただし、本発明は多くの異なる形態による実施が可能であり、以下に示す実施形態、実施例に記載の具体的な例示にのみ限定されるわけでは無い。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different embodiments, and is not limited to the specific examples described in the embodiments and examples shown below.

図1、2は、本実施形態に係るソベント継手内の塗装方法(以下「本方法」という。)の対象となるソベント継手の構造の概略を示す図である。図1は外観の斜視図であり、図2はその断面図である。 FIGS. 1 and 2 are diagrams showing an outline of the structure of a sovent joint that is a target of a painting method (hereinafter referred to as “the present method”) in a sovent joint according to the present embodiment. FIG. 1 is a perspective view of the appearance, and FIG. 2 is a sectional view thereof.

上記するように、本ソベント継手1は、鉛直方向に延びる排水管と水平方向に延びる排水管を接合するために用いることができるものであって、これを用いることで効率的に排水を行うことが可能となる。 As described above, the Sovent joint 1 can be used to join a drainage pipe extending in the vertical direction and a drainage pipe extending in the horizontal direction, and by using this, drainage can be performed efficiently. Is possible.

そしてその構造は、具体的に説明すると、一般的に、鉛直方向上側から延伸する第一の配管T1が接続される天板部材2と、天板部材2の周囲縁を覆うよう天板部材2に接続されつつその断面が鉛直方向上側から下側に行くに従い小さくなる部分を有し、鉛直方向略垂直な方向から第二の配管T2に接続されているとともに、鉛直方向下側において第三の配管T3にも接続される周壁部材3と、周壁部材3内において天板部材2に接続され、鉛直方向上側から下側に延伸するとともに孔41が形成されたプレート4と、を備える。 More specifically, the structure thereof is generally described as a top plate member 2 to which a first pipe T1 extending from the upper side in the vertical direction is connected, and a top plate member 2 so as to cover the peripheral edge of the top plate member 2. It has a portion whose cross section becomes smaller from the upper side to the lower side in the vertical direction while being connected to the second pipe T2 from a direction substantially perpendicular to the vertical direction, and a third in the lower side in the vertical direction. It includes a peripheral wall member 3 that is also connected to the pipe T3, and a plate 4 that is connected to the top plate member 2 in the peripheral wall member 3 and extends from the upper side to the lower side in the vertical direction and has a hole 41 formed therein.

また本ソベント継手1は、マンション等の建物内に設置する前においては、その設置の位置や方向が定まらないものであるが、重力に基づき流れ落ちる排水を効率的に排出させる必要から、建物内に設置する際は、その方向や位置が定まる。そのため、本明細書では、建物内に設置された後の状態に基づき説明することとする。 In addition, the position and direction of installation of this sovent joint 1 are not fixed before it is installed in a building such as a condominium, but it is necessary to efficiently discharge the drainage that flows down due to gravity, so it is necessary to efficiently discharge the drainage into the building. When installing, the direction and position are determined. Therefore, in this specification, the description will be based on the state after being installed in the building.

また本明細書において「鉛直方向」とは、錘を糸で吊り下げた場合において糸が延伸する方向(重力の方向)をいう。また鉛直方向上側とは重力に逆らう側をいい、下側とは重力に従う側をいう。 Further, in the present specification, the "vertical direction" means the direction in which the thread is stretched (the direction of gravity) when the weight is suspended by the thread. The upper side in the vertical direction is the side that opposes gravity, and the lower side is the side that follows gravity.

また、本方法は、具体的に下記のステップを備えるものである。具体的には、(S1)第二の配管から第三の配管への空流を形成するステップ、(S2)第二の配管からソベント継手内に膨張部材を挿入し、プレートとソベント継手内の周壁部材との間に、膨張部材を膨張させて配置し、第二の配管から第三の配管への空流を阻害するステップ、(S3)第二の配管からソベント継手内の天板部材を塗装するステップ、を有する。 Further, this method specifically includes the following steps. Specifically, (S1) a step of forming an air flow from the second pipe to the third pipe, (S2) an expansion member is inserted into the sovent joint from the second pipe, and the plate and the sovent joint are formed. A step of inflating and arranging an expansion member between the peripheral wall member and blocking the airflow from the second pipe to the third pipe, (S3) From the second pipe to the top plate member in the sovent joint. Have a step to paint.

まず、本方法では、上記の通り(S1)第二の配管から第三の配管への空流を形成するステップを有する。本ステップでは、第二の配管から第三の配管への空流を形成することで、塗料を天板部材の下側を効率的に塗布するための布石とする。この場合に形成される空流のイメージを図2に示しておく。 First, in this method, as described above (S1), there is a step of forming an air flow from the second pipe to the third pipe. In this step, by forming an air flow from the second pipe to the third pipe, the paint is used as a stepping stone for efficiently applying the paint to the lower side of the top plate member. The image of the airflow formed in this case is shown in FIG.

次に、本方法では、上記の通り(S2)第二の配管からソベント継手内に膨張部材を挿入し、プレートとソベント継手内の周壁部材との間に、膨張部材を膨張させて配置し、第二の配管から第三の配管への空流を阻害するステップ(以下単に「第二の配管から第三の配管への空流を阻害するステップ」ともいう。)を有する。この場合のイメージを図3に示しておく。 Next, in this method, as described above (S2), an expansion member is inserted into the sovent joint from the second pipe, and the expansion member is expanded and arranged between the plate and the peripheral wall member in the sovent joint. It has a step of inhibiting the air flow from the second pipe to the third pipe (hereinafter, also referred to simply as "a step of inhibiting the air flow from the second pipe to the third pipe"). The image in this case is shown in FIG.

ソベント継手1は、第二の配管T2から第三の配管T3への流体の流れが効率的に形成されるよう構成されている。具体的には、ソベント継手1に対し鉛直方向に対し略垂直な方向から接続される第二の配管T2によって運ばれる排水は、ソベント継手1内において設置される(鉛直方向に対し略平行な方向に延伸している)プレート4に衝突し、水平方向への勢いが減衰し、鉛直方向下側において接続されている第三の配管T3にそのまま流入することになる。そしてここで明らかなように、ソベント継手1内の天板部材2下側(内側)は重力方向とは反対側である。そのため、排水と同様、流体である硬化前の塗料をこのままソベント継手1内に導入したとしても、このままでは天板部材2下側に十分に塗布することができない可能性がある。そこで、本ステップでは、第二の配管T2から第三の配管T3へのそのままの空流を膨張部材を膨張させることで阻害する。これにより、通常の空流を阻害し天板部材2下側に接触する空流を形成することが可能となる。ただし、「第二の配管から第三の配管への空流を阻害する」とは、完全に空流を遮断するのではなく、プレート4に形成される孔41を介して、第二の配管T2から第三の配管T3への迂回空流を形成することが好ましい。プレート4に形成される孔41は天板部材2の下部に近い位置に形成されており、この迂回空流を形成することで天板部材2の下側に効率的に塗料を塗布することが可能となる。 The sovent joint 1 is configured to efficiently form a fluid flow from the second pipe T2 to the third pipe T3. Specifically, the drainage carried by the second pipe T2 connected from the direction substantially perpendicular to the vertical direction with respect to the sovent joint 1 is installed in the sovent joint 1 (direction substantially parallel to the vertical direction). It collides with the plate 4 (which is stretched in the vertical direction), the momentum in the horizontal direction is attenuated, and the force flows into the third pipe T3 connected in the lower side in the vertical direction as it is. And as is clear here, the lower side (inside) of the top plate member 2 in the sovent joint 1 is on the opposite side to the direction of gravity. Therefore, as with drainage, even if the fluid paint before curing is introduced into the sovent joint 1 as it is, it may not be sufficiently applied to the lower side of the top plate member 2 as it is. Therefore, in this step, the air flow as it is from the second pipe T2 to the third pipe T3 is hindered by expanding the expansion member. This makes it possible to block a normal air flow and form an air flow that comes into contact with the lower side of the top plate member 2. However, "inhibiting the airflow from the second pipe to the third pipe" does not mean that the airflow is completely blocked, but means that the second pipe is formed through the hole 41 formed in the plate 4. It is preferable to form a detour airflow from T2 to the third pipe T3. The hole 41 formed in the plate 4 is formed at a position close to the lower part of the top plate member 2, and by forming this detour airflow, the paint can be efficiently applied to the lower side of the top plate member 2. It will be possible.

ここで「膨張部材」は、上記の通り、第二の配管T2と第三の配管T3への空流を阻害することができる限りにおいて限定されるわけでは無いが、第二の配管T2から挿入され、ソベント継手1内に挿入された後、膨張することによって空路を阻害することができる部材である。また、この膨張は、プレート4とソベント管の周壁部材3の間、より具体的には第二の配管T2に近い側のプレート4とソベント管の周壁部材3の間を埋めることができるものであることが好ましい。 Here, as described above, the "expansion member" is not limited as long as it can obstruct the airflow to the second pipe T2 and the third pipe T3, but is inserted from the second pipe T2. It is a member that can obstruct the air passage by expanding after being inserted into the sovent joint 1. Further, this expansion can fill the space between the plate 4 and the peripheral wall member 3 of the sovent pipe, more specifically, between the plate 4 on the side closer to the second pipe T2 and the peripheral wall member 3 of the sovent pipe. It is preferable to have.

膨張部材の具体的な例としては、細長いチューブと、この細長いチューブの先端に付された風船状の部材であってもよく、また、またワイヤー部材と、このワイヤー部材の先端に接続される複数の紐部材と、この複数の紐部材が接続された布状部材とを有するいわゆる帆状部材であってもよい。前者の例は上記図3で示すとおりであり、後者の例については図4に一例を示しておく。本ステップを実行する者は、細長いチューブ又はワイヤーの先端の位置を注視しながら、ソベント継手1内の適切な位置になった際、位置を固定し、十分に膨張部材で流路をふさぎ空流を阻害する。 Specific examples of the inflatable member may be an elongated tube and a balloon-shaped member attached to the tip of the elongated tube, and also a wire member and a plurality connected to the tip of the wire member. It may be a so-called sail-shaped member having the string member of the above and a cloth-like member to which the plurality of string members are connected. An example of the former is as shown in FIG. 3, and an example of the latter is shown in FIG. The person who performs this step, while paying close attention to the position of the tip of the elongated tube or wire, fixes the position when it reaches an appropriate position in the sovent joint 1, and sufficiently blocks the flow path with an expansion member to provide an air flow. Inhibits.

また、本方法では、上記の通り(S3)第二の配管からソベント継手内の天板部材を塗装するステップを有する。すなわち、上記のように、第二の配管T2から第三の配管T3への迂回空流を形成するが、迂回空流はソベント継手1の天板部材2の下面により近い位置を通るため、この迂回空流に沿って流体塗料を運びつつ天板部材2の下面を塗装することが可能となる。このステップによるイメージについて図5に示しておく。 Further, in this method, as described above (S3), there is a step of painting the top plate member in the sovent joint from the second pipe. That is, as described above, a detour airflow from the second pipe T2 to the third pipe T3 is formed, but since the detour airflow passes through a position closer to the lower surface of the top plate member 2 of the sovent joint 1, this is this. It is possible to paint the lower surface of the top plate member 2 while carrying the fluid paint along the detour airflow. The image of this step is shown in FIG.

ところで、本方法においては、第二の配管から第三の配管への空流を阻害するステップの前に、(SA)ソベント継手内を研磨するステップ、を備えることが好ましい。事前にソベント継手1内、より具体的にはソベント継手1内の天板部材2の下側を研磨剤などによって研磨しておくことで、ソベント継手1内を研磨して錆などによる凹凸を切削して平滑にしておくことで、よりソベント管内における塗料の塗布の均一性や確実性を高めることが可能となる。なお、本ステップについては、上記(S3)第二の配管からソベント継手内の天板部材を塗装するステップの前であることが好ましく、上記(S1)第二の配管から第三の配管への空流を形成するステップの前であってもよく、また上記(S1)のステップの後であってもよい。 By the way, in this method, it is preferable to include a step of polishing the inside of the (SA) sovent joint before the step of inhibiting the air flow from the second pipe to the third pipe. By polishing the inside of the sovent joint 1, more specifically, the lower side of the top plate member 2 in the sovent joint 1 with an abrasive or the like in advance, the inside of the sovent joint 1 is polished to cut irregularities due to rust or the like. By smoothing the coating, it is possible to improve the uniformity and certainty of the coating of the paint in the sovent tube. It is preferable that this step is before the step of painting the top plate member in the sovent joint from the second pipe in (S3) above, and from the second pipe to the third pipe in (S1) above. It may be before the step of forming the air flow, or may be after the step of (S1) above.

以上、本方法によって、天板部分に対しても十分な効果を発揮できるソベント継手内の塗装方法を提供することができる。 As described above, according to this method, it is possible to provide a coating method inside the sovent joint that can exert a sufficient effect on the top plate portion.
