Description

本発明は、配管構造および配管構造の施工方法に関する。 The present invention relates to a piping structure and a method of constructing a piping structure.

集合住宅などの一住戸内における給水・給湯配管の大半には、例えば、架橋ポリエチレン管やポリブデン管などの可撓性を有する樹脂製の管材が使用されている。このような管材に接続される継手には、ワンタッチで樹脂管に取り付け可能な継手や、袋ナットやかしめ用のコアなどで締め付けて管材に取り付け可能な継手や、溶着によって管材に取り付け可能な継手などが用いられている。
現場における管材と継手との接続は、作業者の技量により品質が左右されることが多いく、管材と継手との接続不良が生じると、漏水の原因となる虞がある。このため、予め管材と継手とが接続されたプレハブ加工配管を工場で製作し、圧力検査等も経た後でこのプレハブ加工配管を現場にて敷設する方法が行われている。 For most of the water and hot water supply pipes in a single dwelling unit such as an apartment house, flexible resin pipe materials such as cross-linked polyethylene pipes and polybuden pipes are used. The joints connected to such pipe materials include joints that can be attached to resin pipes with a single touch, joints that can be attached to pipe materials by tightening with bag nuts or caulking cores, and joints that can be attached to pipe materials by welding. Etc. are used.
The quality of the connection between the pipe material and the joint at the site often depends on the skill of the operator, and if the connection between the pipe material and the joint is poor, it may cause water leakage. For this reason, a method is used in which a prefabricated pipe in which a pipe material and a joint are connected in advance is manufactured at a factory, and the prefabricated pipe is laid at the site after undergoing a pressure inspection or the like.

ところで、給水・給湯配管の配管構造として、建物の天井の内部に敷設され、壁内を通って設備機器に接続される配管構造が知られている（例えば、特許文献１参照）。しかしながら、建物の天井の内部に梁が設けられていると、梁下に配管を敷設するスペースが無い場合がある。このような場合は、梁に形成されたスリーブに配管を挿入させることがある。 By the way, as a piping structure for water / hot water supply piping, there is known a piping structure that is laid inside the ceiling of a building and connected to equipment through the inside of a wall (see, for example, Patent Document 1). However, if the beam is provided inside the ceiling of the building, there may be no space for laying the pipe under the beam. In such a case, the pipe may be inserted into the sleeve formed on the beam.

特開２０１４−２０１５９号公報Japanese Unexamined Patent Publication No. 2014-2015

しかしながら、プレハブ加工配管を敷設する際に、プレハブ加工配管に分岐継手が設けられていると、分岐継手に接続された配管が干渉してスリーブに挿入させることができないという問題がある。配管が可撓性を有する樹脂管の場合は、配管を曲げてスリーブに挿入させることが考えられるが、局所的に曲げられた部分が座屈して耐圧性能などが低下し漏水などの原因となる虞がある。
また、樹脂管を曲げる場合の最小半径は１５０ｍｍ程度であるが、スリーブにおいて最小半径以上で樹脂管を曲げるためには、スリーブの直径が２００ｍｍ以上である必要がある。しかしながら、梁の強度を考慮すると、梁に２００ｍｍ以上のスリーブを設けることは困難な場合が多い。 However, when laying the prefabricated pipe, if the prefabricated pipe is provided with a branch joint, there is a problem that the pipe connected to the branch joint interferes and cannot be inserted into the sleeve. If the pipe is a flexible resin pipe, it is conceivable to bend the pipe and insert it into the sleeve, but the locally bent part buckles and the pressure resistance performance deteriorates, causing water leakage. There is a risk.
Further, the minimum radius when bending the resin tube is about 150 mm, but in order to bend the resin tube with the minimum radius or more in the sleeve, the diameter of the sleeve needs to be 200 mm or more. However, considering the strength of the beam, it is often difficult to provide the beam with a sleeve of 200 mm or more.

このため、プレハブ加工配管に分岐継手が設けられている場合、現場において分岐継手の近傍で一体配管を切断し、分岐継手が設けられた側と逆側の配管をスリーブに通した後に新たな継手（ソケット）を設けて再度接続している。しかしながら、このような作業に時間や労力がかかるとともに、接続部分の品質が作業者の技量によって左右されるという問題がある。 For this reason, when a branch joint is provided in the prefabricated pipe, the integral pipe is cut in the vicinity of the branch joint at the site, and the pipe on the side opposite to the side where the branch joint is provided is passed through the sleeve, and then a new joint is used. (Socket) is provided and reconnected. However, there is a problem that such work takes time and labor, and the quality of the connection portion depends on the skill of the operator.

そこで、本発明は、プレハブ加工配管を安定した品質でかつ容易に施工することができる配管構造および配管構造の施工方法を提供することを目的とする。 Therefore, an object of the present invention is to provide a pipe structure and a method of constructing a pipe structure, which can easily construct a prefabricated pipe with stable quality.

上記目的を達成するため、本発明に係る配管構造は、管材と継手とが予め接続されてから敷設対象領域に敷設されるプレハブ加工配管の配管構造において、前記敷設対象領域の梁に形成されたスリーブを貫通可能なスリーブ貫通管材と、複数の樹脂管と、前記樹脂管同士を接続する継手と、を有有し、前記第１プレハブ加工配管は、前記第２プレハブ加工配管よりも給水源側に配置されていることを特徴とする。 In order to achieve the above object, the piping structure according to the present invention is formed on the beam of the laying target area in the piping structure of the prefabricated pipe to be laid in the laying target area after the pipe material and the joint are connected in advance. The first prefabricated pipe has a sleeve penetrating pipe material capable of penetrating the sleeve , a plurality of resin pipes, and a joint for connecting the resin pipes, and the first prefabricated pipe is closer to the water supply source than the second prefabricated pipe. It is characterized by being arranged in .

また、本発明に係る配管構造の施工方法では、管材と継手とが予め接続されたプレハブ加工配管を敷設対象領域に敷設する配管構造の施工方法において、前記敷設対象領域の梁に形成されたスリーブを貫通可能なスリーブ貫通管材と複数の樹脂管と、前記樹脂管同士を接続する継手とを有し、給水源側に位置される第１プレハブ加工配管を、前記スリーブの貫通方向の一方側から前記スリーブに前記スリーブ貫通管材を貫通させるようにして配置する第１プレハブ加工配管設置工程と、前記スリーブ貫通管材と接続される接続管材を有する第２プレハブ加工配管を、前記スリーブの貫通方向の他方側に配置する第２プレハブ加工配管配置工程と、前記スリーブ貫通管材と前記接続管材とを接続部材で接続する接続工程と、を有することを特徴とする。 Further, in the method of constructing a piping structure according to the present invention, in the method of constructing a piping structure in which a prefabricated pipe in which a pipe material and a joint are previously connected is laid in a target area for laying, a sleeve formed on a beam in the target area for laying. The first prefabricated pipe, which has a sleeve penetrating pipe material capable of penetrating the sleeve , a plurality of resin pipes, and a joint for connecting the resin pipes, and is located on the water supply source side, is provided from one side of the sleeve penetrating direction. The first prefabricated pipe installation step of arranging the sleeve so as to penetrate the sleeve penetrating pipe material and the second prefabricated pipe having the connecting pipe material connected to the sleeve penetrating pipe material are placed on the other side of the sleeve penetrating direction. It is characterized by having a second prefabricated pipe arranging step of arranging on the side and a connecting step of connecting the sleeve penetrating pipe material and the connecting pipe material with a connecting member.

本発明では、第１プレハブ加工配管のスリーブ貫通管材をスリーブに貫通させた後に、第２プレハブ加工配管の接続管材と接続部材で接続することにより、敷設対象領域にスリーブがある場合でもプレハブ加工配管を容易に敷設することができる。また、第１プレハブ加工配管のスリーブ貫通管材と、第２プレハブ加工配管の接続管材とは接続部材で接続されるため、第１プレハブ加工配管と、第２プレハブ加工配管とを安定した品質で容易に接続することができる。
第１プレハブ加工配管と第２プレハブ加工配管との現場接合部がスリーブ貫通管材と接続管材との接合部となるため、現場接合部を信頼性の高い高品質とすることができる。 In the present invention, the sleeve penetrating pipe material of the first prefabricated pipe is passed through the sleeve and then connected to the connecting pipe material of the second prefabricated pipe with a connecting member, so that the prefabricated pipe is connected even if there is a sleeve in the laying target area. Can be easily laid. Further, since the sleeve penetrating pipe material of the first prefabricated pipe and the connecting pipe material of the second prefabricated pipe are connected by a connecting member, the first prefabricated pipe and the second prefabricated pipe can be easily connected with stable quality. Can be connected to.
Since the on-site joint between the first prefabricated pipe and the second prefabricated pipe serves as the joint between the sleeve penetrating pipe material and the connecting pipe material, the on-site joint can be made of highly reliable and high quality.

また、本発明に係る配管構造では、前記スリーブは、横方向に配置されていてもよい。 Further, in the piping structure according to the present invention, the sleeves may be arranged in the lateral direction.

樹脂管５と継手（スリーブ貫通管材７、接続管材８）を施工現場で接続することはなく、第１プレハブ加工配管２と第２プレハブ加工配管３との現場接合部がスリーブ貫通管材７と接続管材８との接合部となるため、現場接合部を信頼性の高い高品質とすることができる。 Next, the operation and effect of the piping structure and the construction method of the piping structure according to the first embodiment of the present invention described above will be described with reference to the drawings.
In the piping structure and the construction method of the piping structure according to the first embodiment of the present invention described above, after the sleeve penetrating pipe material 7 of the first prefabricated pipe 2 is passed through the sleeve 15, the connecting pipe material 8 of the second prefabricated pipe 3 is used. By connecting with and a connecting member, the prefabricated pipe can be easily laid even when the sleeve 15 is in the laying target area. Further, since the sleeve penetrating pipe material 7 of the first prefabricated pipe 2 and the connecting pipe material 8 of the second prefabricated pipe 3 are connected by a connecting member, the first prefabricated pipe 2 and the second prefabricated pipe 3 Can be easily connected with stable quality.
The resin pipe 5 and the joint (sleeve through pipe material 7, connecting pipe material 8) are not connected at the construction site, and the on-site joint between the first prefabricated pipe 2 and the second prefabricated pipe 3 is connected to the sleeve through pipe material 7. Since it is a joint with the pipe material 8, the on-site joint can be made of highly reliable and high quality.

また、接続部材４がファスナクリップであることにより、接続部材４によってスリーブ貫通管材７と接続管材８とを容易にかつ確実に接続することができる。また、ファスナクリップはスリーブ貫通管材７と接続管材８との接続部に容易に着脱することができるため、スリーブ貫通管材７と接続管材８とを外して行う点検（例えばОリング７２３の点検等）を容易に行うことができる。さらに、接続部材４の装着状態を目視で容易に確認することできるため、接続部材４の装着の不具合を容易に判別することができる。 Further, since the connecting pipe material 8 is a three-way branch joint, if the connecting pipe material 8 is provided in the vicinity of the sleeve 15, the pipe can be easily branched in the vicinity of the sleeve 15.
Further, since the connecting member 4 is a fastener clip, the sleeve penetrating pipe material 7 and the connecting pipe material 8 can be easily and surely connected by the connecting member 4. Further, since the fastener clip can be easily attached to and detached from the connection portion between the sleeve penetrating pipe material 7 and the connecting pipe material 8, inspection performed by removing the sleeve penetrating pipe material 7 and the connecting pipe material 8 (for example, inspection of the О ring 723). Can be easily performed. Further, since the mounting state of the connecting member 4 can be easily visually confirmed, it is possible to easily determine the mounting defect of the connecting member 4.

By doing so, when the pressure inspection is performed without the fastener clip of the connecting member 4 attached, the resin pipe moves by the axial force and the connecting portion is pulled out, so that an abnormality can be easily detected. it can. In general, when the resin pipe is directly supported and fixed to the support member, the movement in the axial direction is restrained and the rigidity of the resin pipe itself suppresses the disconnection of the connecting portion even if the fastener clip is not attached, which is abnormal. May not be detected.
