Description

本発明は、下水本管などの主管路に取付管などの枝管路を接続するための接続支管に関する。   The present invention relates to a connecting branch pipe for connecting a branch pipe line such as a mounting pipe to a main pipe line such as a sewage main pipe.

一般に、各家庭の公共ますに接続された取付管と下水本管とを接続する際に、下水本管から上流側への配管を行う場合には、下水本管の所定位置にサドル型の支管を取り付けて下水本管を分岐し、該支管に取付管を接続する配管工事を行う。
そして、下水本管に支管を取り付ける場合には、下水本管の所定位置にホルソー等を用いて開口部を設けて、該開口部にサドル型の支管を装着し、接着剤やパテ状接合剤を使用して該支管を該下水本管に固定していた。
しかし、接着剤やパテ状接合剤を使用する場合には、配管工事の省力化や施工の確実性を図ることが困難であった。 In general, when connecting the installation pipe connected to the public sewage of each household to the sewage main pipe, when piping from the sewage main pipe to the upstream side, a saddle-type branch pipe is placed at a predetermined position of the sewage main pipe. Is installed to branch the sewage main pipe and connect the pipe to the branch pipe.
When attaching a branch pipe to the sewage main pipe, an opening is provided at a predetermined position of the sewage main pipe using a horuseau or the like, a saddle-type branch pipe is attached to the opening, and an adhesive or putty-like bonding agent is provided. Was used to fix the branch pipe to the sewage main pipe.
However, when an adhesive or putty-like bonding agent is used, it has been difficult to save labor in piping work and to ensure construction reliability.

そこで、従来、配管工事の省力化や施工の確実性を図るために、接着剤やパテ状接合剤を使用することなく、該支管を該下水本管に機械的に固定することができる分岐管継手や分岐接続管継手が提案されている。
上記分岐管継手としては、主管路の開口部の内側から係止部材を外側に臨出させ、その外側にサドル部材を装着し、該係止部材に枝管路が接続される接続口が設けられている接続部材を回転させて螺着する構成のものが提供されている（例えば特許引用文献１〜３参照）。 Therefore, conventionally, a branch pipe that can mechanically fix the branch pipe to the sewage main pipe without using an adhesive or a putty-like bonding agent in order to save labor in piping work and ensure the reliability of the construction. Joints and branch connection pipe joints have been proposed.
As the above-mentioned branch pipe joint, a locking member protrudes from the inside of the opening of the main pipeline, and a saddle member is mounted on the outside, and a connection port for connecting the branch pipeline to the locking member is provided. There is a configuration in which a connecting member is rotated and screwed (for example, see Patent Citations 1 to 3).

特許第３３９６１２８号公報Japanese Patent No. 3396128 意匠登録第１０７５２２６号公報Design Registration No. 1075226 意匠登録第１０７５２２７号公報Design Registration No. 1075227

上記分岐管継手にあっては、接続部材とサドル部材との水密性を維持するために、接続部材とサドル部材との間にパッキンを介在させることが望ましい。しかし水密性を向上させるために該パッキンを該接続部材と該サドル部材との間に緊密に介在させると、該接続部材を該サドル部材に螺着する場合、該接続部材の回転抵抗が大きくなって施工困難あるいは不可能になる。   In the branch pipe joint, in order to maintain the watertightness between the connecting member and the saddle member, it is desirable to interpose packing between the connecting member and the saddle member. However, if the packing is closely interposed between the connecting member and the saddle member in order to improve water tightness, the rotational resistance of the connecting member increases when the connecting member is screwed to the saddle member. It becomes difficult or impossible to install.

本発明は上記従来の課題を解決し、パッキンによる水密性を向上させても接続部材を係止部材に容易に螺着出来るようにすることを目的とし、かくして本発明は主管路２に枝管路を接続するための接続支管１であって、主管路２の開口部３の周縁に係止される複数個の係止爪４，５が設けられている係止部材６と、該係止部材６に嵌着されるとともに主管路２上に装着されるサドル部材７と、該サドル部材７に挿着されるとともに枝管路が接続される接続口８が設けられている接続部材９とを有しており、一方または両方の係止爪４は枢着ピン１１を介して該係止部材６に回動可能に枢着されており、該枢着された係止爪４を回動させることによって該係止爪４は該主管路２の開口部３を通過可能とされ、また、該接続部材９を該係止部材６に螺着することによって該係止爪４の回動が阻止されて該係止爪４は該主管路２の開口部３を通過不可能とされ、更に該接続部材９の下部には下向きの段面２３が周設されており、該段面２３直下には弾性体を材料とするリング状のパッキン２４が嵌着されており、該パッキン２４は該接続部材９を該係止部材６に螺着する場合、当初は該接続部材９の外周面と該サドル部材７内周面とに密接せず、該接続部材９を該係止部材６に螺着して行くにつれて、該パッキン２４は該段面２３と該係止部材上周面６Ａまたは該サドル部材７内周面に形成されている上向き段面１６とによって挟圧され、巾を拡大することによって該接続部材９の外周面と該サドル部材７の内周面とに密着することを特徴とする接続支管１を提供するものである。
通常、該複数個の係止爪は主管路の軸方向に沿って設けられている。 An object of the present invention is to solve the above-mentioned conventional problems and to make it possible to easily screw a connecting member to a locking member even if the water tightness by packing is improved.

One or both of the locking claws 4 are pivotally attached to the locking member 6 via a pivoting pin 11, and the pivoted locking claw 4 is pivoted. By doing so, the locking claw 4 can pass through the opening 3 of the main pipeline 2, and the connecting member 9 is connected to the locking member 6. By screwing, the locking claw 4 is prevented from rotating, so that the locking claw 4 cannot pass through the opening 3 of the main pipe line 2. A ring-shaped packing 24 made of an elastic material is fitted immediately below the stepped surface 23, and the packing 24 screws the connecting member 9 onto the locking member 6. In the case of wearing, the packing 24 is not in close contact with the outer peripheral surface of the connecting member 9 and the inner peripheral surface of the saddle member 7 at first, and the packing 24 is moved to the locking member 6 as the connecting member 9 is screwed. It is clamped by the step surface 23 and the upward step surface 16 formed on the inner peripheral surface of the locking member upper peripheral surface 6A or the saddle member 7, and by expanding the width, the outer peripheral surface of the connecting member 9 and the The connection branch pipe 1 is provided, which is in close contact with the inner peripheral surface of the saddle member 7.
Usually, the plurality of locking claws are provided along the axial direction of the main pipeline.

そして該接続部材９の下部において、上記下向きの段面２３の下側には更に下向きの係止段面２０が形成されており、一方該係止部材６の上部内周面には上向きの係止段面６Ａが形成されており、該接続部材９の該係止部材６に対する螺着が略完了した時点で、該接続部材９の係止段面２０と該係止部材６の係止段面６Ａとが当接するように設定することによって、該接続部材９の更なる螺入が阻止されるか、あるいは該接続部材９の下部において、該下向きの段面２３の下側には更に下向きの係止段面２０が形成されており、一方該サドル部材７の上向き段面２７Ａの下段には更に上向きの係止段面２８Ａが形成されており、該接続部材９の該係止部材７に対する螺着が略完了した時点で、該接続部材９の係止段面２０と該サドル部材の係止断面２８Ａとが当接するように設定することによって、該接続部材９の更なる螺入が阻止されることが望ましい。   In the lower part of the connecting member 9, a downward locking step surface 20 is formed below the downward step surface 23, while an upward engagement is formed on the upper inner peripheral surface of the locking member 6. A stop step surface 6A is formed, and when the screwing of the connecting member 9 to the locking member 6 is substantially completed, the locking step surface 20 of the connecting member 9 and the locking step of the locking member 6 are By setting the surface 6A so as to abut, further screwing of the connecting member 9 is prevented, or at the lower part of the connecting member 9, the lower side of the stepped surface 23 is further downward. On the other hand, an upward locking step surface 28A is formed below the upward step surface 27A of the saddle member 7, and the locking member 7 of the connecting member 9 is formed. When the screwing to the saddle member is almost completed, the engagement step surface 20 of the connecting member 9 and the saddle member are engaged with each other. By the cross-section 28A is set so as to abut, it is desirable to further screwing of the connecting member 9 is prevented.

更に該接続部材９の下向きの段面２３の直下に嵌着されているパッキン２４の下側には該係止部材６の上周面６Ａに下面が当接するリング状の押圧部材２６が遊嵌されており、該接続部材９を該係止部材６に螺着して行くにつれて、該パッキン２４は該段面２３と該押圧部材２６を介して該係止部材６の上周面６Ａとによって挟圧される構成であっても良く、その場合該係止部材６の係止段面６Ａは該押圧部材２６の内周に形成されていることが望ましい。   Further, a ring-shaped pressing member 26 whose lower surface abuts on the upper peripheral surface 6A of the locking member 6 is loosely fitted on the lower side of the packing 24 fitted immediately below the downward step surface 23 of the connecting member 9. As the connection member 9 is screwed onto the locking member 6, the packing 24 is formed by the upper peripheral surface 6 </ b> A of the locking member 6 through the step surface 23 and the pressing member 26. In this case, the locking step surface 6A of the locking member 6 is preferably formed on the inner periphery of the pressing member 26.

〔作用〕
本発明の接続支管１では、係止部材６に枢着された係止爪４を回動させて、該係止爪４を外側から該主管路２の開口部３の内側に通過させ、主管路２の開口部３の周縁内側に該係止爪４，５を係止させた後に該接続部材９を該係止部材６に螺着して、該係止爪４の回動を阻止し、該係止爪４が該主管路２の開口部３を通過できないようにする。
上記接続部材９を該係止部材６に螺着して行くと、当初は該パッキン２４は該接続部材９外周面と該サドル部材７内周面とに密着しないから該接続部材９は容易に回転させて該係止部材６に容易に螺着出来る。更に該接続部材９を該係止部材６に螺着していくと、該接続部材９の下向きの段面２３直下のパッキン２４は該段面２３と該係止部材６の上周面６Ａあるいは該サドル部材７の内周に形成されている上向きの段面１６あるいは押圧部材２６を介する場合には該押圧部材２６の上周面２７に挟圧され、該パッキン２４は巾を拡大することによって該接続部材９外周面と該サドル部材７内周面とに密着する。それにつれて該接続部材９の回転抵抗は次第に大きくなり、最終的には螺着困難となる。この時点で該接続部材９の螺着は完了する。
該接続部材９の下部において、上記下向きの段面２３の下側には更に下向きの係止段面２０が形成されており、一方外係止部材６の上記内周面には上向きの係止段面２８Ａが形成するか、あるいは該接続部材９の下部において、該下向きの段面２３の下側には更に下向きの係止段面２０が形成されており、一方該サドル部材７の上向き段面２７Ａの下段には更に上向きの係止段面２８Ａが形成し、該接続部材９の該係止部材６に対する螺着が略完了した時点で、該接続部材９の係止段面２０と該サドル部材７の係止段面１６とが当接するように設定しておけば、該接続部材９の更なる螺入が阻止され、過剰締付けが回避される。
押圧部材２６を介在させると、該押圧部材２６はパッキン２４および係止部材６に対して相対回転することが可能であるから、該接続部材９の回転抵抗を更に軽減することができる。該押圧部材２６を介在させる場合には、該係止段面１６は該押圧部材２６の内面に形成する。 [Action]
In the connection branch pipe 1 of the present invention, the latching claw 4 pivotally attached to the latching member 6 is rotated so that the latching claw 4 passes from the outside to the inside of the opening 3 of the main pipeline 2. After the locking claws 4 and 5 are locked to the inner periphery of the opening 3 of the path 2, the connecting member 9 is screwed to the locking member 6 to prevent the locking claws 4 from rotating. The locking claw 4 is prevented from passing through the opening 3 of the main pipeline 2.
When the connecting member 9 is screwed onto the locking member 6, the packing 24 initially does not come into close contact with the outer peripheral surface of the connecting member 9 and the inner peripheral surface of the saddle member 7. It can be easily screwed onto the locking member 6 by rotating. Further, when the connecting member 9 is screwed onto the locking member 6, the packing 24 immediately below the downward step surface 23 of the connecting member 9 is connected to the step surface 23 and the upper peripheral surface 6A of the locking member 6. When the upward stepped surface 16 or the pressing member 26 formed on the inner periphery of the saddle member 7 is interposed, the pressing member 26 is clamped by the upper peripheral surface 27, and the packing 24 is expanded in width. The connection member 9 is in close contact with the outer peripheral surface and the inner peripheral surface of the saddle member 7. Accordingly, the rotational resistance of the connection member 9 gradually increases, and finally it becomes difficult to screw. At this time, the screwing of the connecting member 9 is completed.
In the lower part of the connecting member 9, a downward locking step surface 20 is formed below the downward step surface 23, while an upward locking is formed on the inner peripheral surface of the outer locking member 6. A stepped surface 28A is formed, or a lower locking stepped surface 20 is formed on the lower side of the downwardly facing stepped surface 23 at the lower portion of the connecting member 9, while the upwardly facing stepped side of the saddle member 7 is formed. A further upward locking step surface 28A is formed at the lower stage of the surface 27A, and when the screwing of the connecting member 9 to the locking member 6 is substantially completed, the locking step surface 20 of the connecting member 9 and the If it sets so that the latching step surface 16 of the saddle member 7 may contact | abut, the further screwing of this connection member 9 will be blocked | prevented and an overtightening will be avoided.
When the pressing member 26 is interposed, the pressing member 26 can rotate relative to the packing 24 and the locking member 6, so that the rotational resistance of the connecting member 9 can be further reduced. When the pressing member 26 is interposed, the locking step surface 16 is formed on the inner surface of the pressing member 26.

〔効果〕
したがって、該接続部材９を該係止部材６に螺着した場合には、該係止爪４，５は該開口部３の周縁に確実に係止されているので、係止不良や漏水が発生するのを防止して、施工の確実性を向上させることができる。そして接続部材９を該係止部材６に螺着する場合には、当初はパッキン２４にもとづく該接続部材９の回転抵抗は小さいので、施工作業は極めて容易となり、また該接続部材９を該係止部材６に螺着するにつれてパッキン２４が挟圧されて巾を拡大して高い水密性が得られる。 〔effect〕
Therefore, when the connection member 9 is screwed to the locking member 6, the locking claws 4 and 5 are securely locked to the peripheral edge of the opening 3. Generation | occurrence | production can be prevented and the certainty of construction can be improved. When the connection member 9 is screwed to the locking member 6, since the rotational resistance of the connection member 9 based on the packing 24 is initially small, the construction work becomes very easy, and the connection member 9 is connected to the engagement member 9. The packing 24 is clamped as it is screwed to the stop member 6, and the width is increased to obtain high water tightness.

Since one of the locking claws 4 is not screwed, the one locking claw 4 remains in a rotatable state.

その後、下水本管２の所定位置にホルソー等の工具（図示せず）を用いて開口部３を設ける。
そして、係止部材６の他方の係止爪５を下水本管２の開口部３の周縁の内周面に係止させるとともに、図３において矢印で示すように、一方の係止爪４を枢着ピン１１を中心として内側に回動させて、該一方の係止爪４が該開口部３を通過可能な状態とする。 Thereafter, an opening 3 is provided at a predetermined position of the sewage main pipe 2 using a tool (not shown) such as a horuseau.
Then, the other locking claw 5 of the locking member 6 is locked to the inner peripheral surface of the peripheral edge of the opening 3 of the sewage main pipe 2 and, as shown by an arrow in FIG. By rotating inward about the pivot pin 11, the one locking claw 4 is allowed to pass through the opening 3.

次いで、図４に示すように、該係止部材６の一方の係止爪４を下水本管２の開口部３を通過させた後、該一方の係止爪４を枢着ピン１１を中心として外側に回動させて、該一方の係止爪４を該開口部３の周縁の内周面に係止させる。
その後、図４において矢印で示すように、把手２５を手掛りとして接続部材９を回転させて、接続部材９の挿入部１８のねじ部１９を該係止部材６の係止爪４，５のねじ溝１２にまで螺着させる（図５参照）。そうすると、一方の係止爪４の上部も、接続部材９の挿入部１８の外周面とサドル部材７の内周面とによって挟持されるため、該一方の係止爪４の回動が阻止され、該一方の係止爪４は該下水本管２の開口部３を通過不可能とされる。 Next, as shown in FIG. 4, after one locking claw 4 of the locking member 6 is passed through the opening 3 of the sewage main pipe 2, the one locking claw 4 is centered on the pivot pin 11. The one locking claw 4 is locked to the inner peripheral surface of the peripheral edge of the opening 3.
Thereafter, as shown by arrows in FIG. 4, the connection member 9 is rotated with the handle 25 as a clue, and the screw portion 19 of the insertion portion 18 of the connection member 9 is screwed into the locking claws 4, 5 of the locking member 6. Screw into the groove 12 (see FIG. 5). Then, since the upper part of one latching claw 4 is also pinched | interposed by the outer peripheral surface of the insertion part 18 of the connection member 9, and the inner peripheral surface of the saddle member 7, rotation of this one latching claw 4 is blocked | prevented. The one locking claw 4 cannot pass through the opening 3 of the sewage main pipe 2.

このとき、接続部材９の挿入部１８のねじ部１９を係止部材６および係止爪４，５のねじ溝１２に螺着していくと、該係止部材６は係止爪４，５と共に接続部材９および該サドル部材７に対して相対的に引き上げられ、係止爪４，５の係止板１０の上面とサドル部材７のサドル板１４の下面とによって下水本管２の開口部３の周縁が挟持され、持続支管１は下水本管２に確実に固定されることとなる。   At this time, when the screw portion 19 of the insertion portion 18 of the connecting member 9 is screwed into the screw groove 12 of the locking member 6 and the locking claws 4, 5, the locking member 6 is locked to the locking claws 4, 5. The connection member 9 and the saddle member 7 are lifted relatively to each other, and the opening of the sewage main pipe 2 is formed by the upper surface of the locking plate 10 of the locking claws 4 and 5 and the lower surface of the saddle plate 14 of the saddle member 7. The peripheral edge of 3 is clamped, and the continuous branch pipe 1 is securely fixed to the sewage main pipe 2.

この場合、該接続部材９を該係止部材６に螺着して行く過程において、図４に示す初期の状態では、該接続部材９のフランジ部２１の段面２３と該押圧部材２６の上周面２７との間に介在する該パッキン２４は該段面２３と該上周面２７とによって挟圧されておらず、該押圧部材２６は該サドル部材７の当接段部１６上に乗架し、該押圧部材２６の中段部３０と該接続部材９の係止段部２０との間には隙間Ｓが存在する。したがって該接続部材９の外周面と該サドル部材７の内周面とに密着しないから、該接続部材９の回転に該パッキン２４は殆ど干渉せず、該接続部材９を回転させて該係止部材６に螺着して行くことは極めて容易である。   In this case, in the process of screwing the connecting member 9 to the locking member 6, in the initial state shown in FIG. 4, the upper surface of the stepped surface 23 of the flange portion 21 of the connecting member 9 and the pressing member 26 The packing 24 interposed between the peripheral surface 27 is not clamped by the step surface 23 and the upper peripheral surface 27, and the pressing member 26 is placed on the contact step portion 16 of the saddle member 7. A gap S exists between the middle step 30 of the pressing member 26 and the locking step 20 of the connecting member 9. Therefore, the outer peripheral surface of the connecting member 9 and the inner peripheral surface of the saddle member 7 are not in close contact with each other, so that the packing 24 hardly interferes with the rotation of the connecting member 9, and the connecting member 9 is rotated to be locked. It is very easy to screw onto the member 6.

該接続部材９を該係止部材６に螺着して行くにつれ、前記したように該係止部材６は該接続部材９および該サドル部材７に対して相対的に引き上げられ、それにつれて該押圧部材２６は該係止部材６によって押上げられ、該パッキン２４は該接続部材９のフランジ部２１の段面２３と該押圧部材２６の上周面２７との間で次第に挟圧されて厚みを縮小しかつ巾を拡大して該接続部材９外周面と該サドル部材７内周面とに圧接密着し、それに伴って該接続部材９の回転抵抗は漸増する。しかしこの状態にあっても該接続部材９と該係止部材６との間には押圧部材２６が介在し、該押圧部材２６は該接続部材９の回転に伴ってパッキン２４を介してサドル部材７に対して回転し、該接続部材９の回転抵抗を軽減する。
前記したように該押圧部材２６の上周面２７は外側に低く傾斜するテーパー面とされているので、該パッキン２４が該接続部材９のフランジ部２１の断面２３と該押圧部材２６の上周面２７との間で挟圧された時、該パッキン２４の材料がサドル部材７内周面側に逃げ、かつ該パッキン２４は拡径し、該サドル部材７内周面に緊密に圧接するので、高い水密性が得られる。 As the connecting member 9 is screwed onto the locking member 6, the locking member 6 is lifted relative to the connecting member 9 and the saddle member 7 as described above, and the pressing member is accordingly pressed. The member 26 is pushed up by the locking member 6, and the packing 24 is gradually sandwiched between the step surface 23 of the flange portion 21 of the connecting member 9 and the upper peripheral surface 27 of the pressing member 26 to increase the thickness. The width and width of the connecting member 9 are reduced and brought into close contact with the inner peripheral surface of the saddle member 7 and the rotational resistance of the connecting member 9 gradually increases. However, even in this state, a pressing member 26 is interposed between the connecting member 9 and the locking member 6, and the pressing member 26 is connected to the saddle member via the packing 24 as the connecting member 9 rotates. 7 to reduce the rotational resistance of the connecting member 9.
As described above, since the upper peripheral surface 27 of the pressing member 26 is a tapered surface that is inclined to the outside, the packing 24 has a cross section 23 of the flange portion 21 of the connecting member 9 and the upper periphery of the pressing member 26. Since the material of the packing 24 escapes to the inner peripheral surface side of the saddle member 7 when sandwiched between the surface 27 and the packing 24 is expanded in diameter, it is in close pressure contact with the inner peripheral surface of the saddle member 7. High water tightness can be obtained.

最終的には図５に示すように該押圧部材２６の中段部３０が該接続部材９の係止段部２０に当接して該接続部材９の更なる回転、即ち更なる螺入が阻止されて該接続部材９の螺着が完了する。
このようにして該接続部材９の螺着が完了した時点において、サドル部材７の内周下面と下水本管２の上面との間には第一パッキン１５が介在されているので、該第一パッキン１５によって該サドル部材７と該下水本管２との間が水密状態とされている。また、サドル部材７の内周面と接続部材９の外周面との間には上記したような巾を拡大した第二パッキン２４が介在し密着されているので、該第二パッキン２４によって該サドル部材７と該接続部材９との間が高度な水密状態にされている（図５および図６参照）。
更に該接続部材９を螺着する際には該接続部材９の螺入圧が該押圧部材２６の外側下周面２９を介してサドル部材７の当接部段部１６に受止され、該サドル部材７のサドル板１４を介して下水本管２に伝達分散されるから、該接続部材９の螺入圧による押圧部材２６やサドル部材７の変形、破損が防止される。 Finally, as shown in FIG. 5, the middle step portion 30 of the pressing member 26 abuts against the locking step portion 20 of the connection member 9 to prevent further rotation of the connection member 9, that is, further screwing. Thus, the screwing of the connecting member 9 is completed.
Since the first packing 15 is interposed between the inner peripheral lower surface of the saddle member 7 and the upper surface of the sewage main pipe 2 when the connection member 9 is screwed in this way, the first The packing 15 provides a watertight state between the saddle member 7 and the sewage main pipe 2. Further, since the second packing 24 having an enlarged width is interposed between the inner peripheral surface of the saddle member 7 and the outer peripheral surface of the connecting member 9, the saddle member 7 is in close contact with the saddle member 7. The space between the member 7 and the connecting member 9 is highly watertight (see FIGS. 5 and 6).
Further, when the connecting member 9 is screwed, the screwing pressure of the connecting member 9 is received by the contact portion step portion 16 of the saddle member 7 through the outer lower peripheral surface 29 of the pressing member 26, and Since it is transmitted and distributed to the sewage main pipe 2 through the saddle plate 14 of the saddle member 7, the pressing member 26 and the saddle member 7 are prevented from being deformed or damaged by the screwing pressure of the connecting member 9.

このように下水本管２の所定位置に接続支管１を取り付けて下水本管２を分岐した後、該接続支管１の接続部材９のゴム輪受口８に取付管を挿入して接続し、配管工事が完了する。   After attaching the connection branch 1 to the predetermined position of the sewage main pipe 2 and branching the sewage main pipe 2 in this way, the connection pipe is inserted into the rubber ring receiving port 8 of the connection member 9 of the connection branch 1 and connected. Piping work is completed.

上記の接続支管１では、接続部材９を係止部材６に螺着することによって、二つの係止爪４，５が下水本管２の開口部３の周縁に確実に係止されるため、係止不良や漏水が発生するのを防止できる。また、上記の接続支管１では、一方の係止爪４が係止した状態でなければ、接続部材９を係止部材６に螺着することができないので、係止爪４，５の係止し忘れを確実に防止することができ、したがって、施工の確実性を向上させることができる。その上、上記の接続支管１では、施工作業が簡便かつ容易であるため、配管工事の省力化を図ることができる。   In the above connecting branch 1, the two locking claws 4, 5 are securely locked to the periphery of the opening 3 of the sewage main pipe 2 by screwing the connecting member 9 to the locking member 6. It is possible to prevent the occurrence of poor locking and water leakage. Further, in the connection branch pipe 1, since the connection member 9 cannot be screwed to the locking member 6 unless one locking claw 4 is locked, the locking claws 4, 5 are locked. Forgetting can be prevented with certainty, and therefore the reliability of construction can be improved. In addition, since the construction work is simple and easy in the connection branch pipe 1 described above, it is possible to save labor in the piping work.

また、接続部材９とサドル部材７とを組み付けたときに、サドル部材７の環状係合爪１７が接続部材９の係合突環２２に係合して保持されているので、組付け状態で該接続部材９と該サドル部材７とが分離することがない。更に、接続部材９と係止部材６とを組み付けたときには、該接続部材９の挿入部１８のねじ部１９が該係止部材６のねじ溝１２に螺着して固定されているので、組付け状態で該接続部材９と該係止部材６とが分離することがない。   In addition, when the connecting member 9 and the saddle member 7 are assembled, the annular engaging claw 17 of the saddle member 7 is engaged with and held by the engaging protrusion 22 of the connecting member 9. The connecting member 9 and the saddle member 7 are not separated. Further, when the connecting member 9 and the locking member 6 are assembled, the screw portion 19 of the insertion portion 18 of the connecting member 9 is screwed and fixed to the screw groove 12 of the locking member 6. The connecting member 9 and the locking member 6 are not separated in the attached state.

更に、一方の係止爪４が枢着ピン１１を介して係止部材６に回動可能にかつ一体的に枢着されているので、該一方の係止爪４を円滑に回動させることができ、作業時に該一方の係止爪４が落下することがないため、施工作業をスムーズに行うことができ、施工の作業性が向上する。   Further, since the one locking claw 4 is pivotally and integrally pivotally attached to the locking member 6 via the pivot pin 11, the one locking claw 4 can be smoothly rotated. Since one of the locking claws 4 does not fall during the work, the construction work can be performed smoothly and the workability of the construction is improved.

また更に、接続部材９の挿入部１８のねじ部１９を係止部材６のねじ溝１２に螺着したときに、一方の係止爪４の上部を接続部材９の挿入部１８の外周面とサドル部材７の内周面とで挟持することによって、該一方の係止爪４の回動を阻止できかつ変形を少なくすることができるので、枢着ピン１１にかかる負担を小さくすることができ、該枢着ピン１１が折れるおそれがほとんどない。
その上、たとえ枢着ピン１１が折れた場合であっても、該接続部材９は該係止部材６に螺着して固定されており、一方の係止爪４は該サドル部材７の外周面と該接続部材９の内周面とに挟持されているので、該一方の係止爪４の係合が外れることがなく、該一方の係止爪４が内側に落下することがない。 Furthermore, when the screw part 19 of the insertion part 18 of the connecting member 9 is screwed into the screw groove 12 of the locking member 6, the upper part of one locking claw 4 is connected to the outer peripheral surface of the insertion part 18 of the connecting member 9. By pinching with the inner peripheral surface of the saddle member 7, the rotation of the one locking claw 4 can be prevented and the deformation can be reduced, so the burden on the pivot pin 11 can be reduced. There is almost no possibility that the pivot pin 11 will break.
In addition, even when the pivot pin 11 is broken, the connecting member 9 is screwed and fixed to the locking member 6, and one locking claw 4 is connected to the outer periphery of the saddle member 7. Since it is clamped by the surface and the inner peripheral surface of the connecting member 9, the engagement of the one locking claw 4 is not released, and the one locking claw 4 does not fall inward.

また、該二つの係止爪４，５が下水本管２の軸方向に沿って設けられているので、下水本管２の開口部３の周縁の最も高い位置に係止爪４，５を係止させることができる。
更に、該二つの係止爪４，５が下水本管２の軸方向に沿って設けられているため、接続支管１が下水本管２の軸に対して傾いた状態で装着された場合であっても、係止爪４，５が取付管の管底より下に位置することがない。 In addition, since the two locking claws 4 and 5 are provided along the axial direction of the sewage main pipe 2, the locking claws 4 and 5 are placed at the highest position on the periphery of the opening 3 of the sewage main pipe 2. It can be locked.
Further, since the two locking claws 4 and 5 are provided along the axial direction of the sewage main pipe 2, the connecting branch pipe 1 is mounted with being inclined with respect to the axis of the sewage main pipe 2. Even if it exists, the latching claws 4 and 5 are not located below the tube bottom of the attachment tube.

図７および図８には本発明の第２実施例が示されている。
本実施例にあっては、実施例１において使用された押圧部材２６を使用せず、それに代えてサドル部材７の内周から上段面２７Ａと下段面２８Ａとからなる２段フランジ部２６Ａを一体的に突設する。更に該サドル部材７の当接段部１６を省略する。
本実施例では接続部材９を該係止部材６に螺着して行く初期の状態では、該接続部材９のフランジ部２１の段面２３とサドル部材７の二段フランジ部２６Ａの上段面２７Ａとの間に介在するパッキン２４は該段面２３と該上段面２７Ａとによって挟圧されておらず、該二段フランジ部２６Ａの下段面２８Ａと該接続部材９の係止段面２０との間には隙間Ｓが存在する。したがって該接続部材９の回転にパッキン２４は殆ど干渉せず、該接続部材９を回転させて該係止部材６に螺着して行くことは極めて容易である。 7 and 8 show a second embodiment of the present invention.
In this embodiment, the pressing member 26 used in the first embodiment is not used, and instead, a two-step flange portion 26A composed of an upper step surface 27A and a lower step surface 28A is integrated from the inner periphery of the saddle member 7. Project. Further, the contact step 16 of the saddle member 7 is omitted.
In this embodiment, in the initial state where the connection member 9 is screwed to the locking member 6, the step surface 23 of the flange portion 21 of the connection member 9 and the upper step surface 27A of the two-step flange portion 26A of the saddle member 7 are used. The packing 24 interposed therebetween is not clamped by the step surface 23 and the upper step surface 27A, and the lower step surface 28A of the two-step flange portion 26A and the locking step surface 20 of the connecting member 9 There is a gap S between them. Therefore, the packing 24 hardly interferes with the rotation of the connecting member 9, and it is very easy to rotate the connecting member 9 and screw it onto the locking member 6.

該接続部材９を該係止部材６に螺着して行くにつれ、実施例１と同様に該係止部材６は該接続部材９および該サドル部材７に対して相対的に引き上げられ、該パッキン２４は該接続部材９のフランジ部２１の段面２３と該サドル部材７の二段フランジ部２６Ａの上段面２７Ａとの間で次第に挟圧されて厚みを縮小しかつ巾を拡大して該接続部材９外周面と該サドル部材７内周面とに圧接密着し、それに伴って該接続部材９の回転抵抗は漸増する。最終的には図８に示すように該サドル部材７の二段フランジ部２６Ａの下段面２８Ａが該接続部材９の係止段面２０に当接して該接続部材９の更なる回転、即ち更なる螺入が阻止されて該接続部材９の螺着が略完了する。そしてこのようにして巾が拡大した第二パッキン２４によって該サドル部材７と該接続部材９との間が高度な水密状態にされている。   As the connecting member 9 is screwed onto the locking member 6, the locking member 6 is pulled up relative to the connecting member 9 and the saddle member 7 in the same manner as in the first embodiment. 24 is gradually pinched between the step surface 23 of the flange portion 21 of the connecting member 9 and the upper step surface 27A of the two-step flange portion 26A of the saddle member 7 to reduce the thickness and increase the width. The outer peripheral surface of the member 9 and the inner peripheral surface of the saddle member 7 are brought into pressure contact with each other, and accordingly, the rotational resistance of the connecting member 9 gradually increases. Finally, as shown in FIG. 8, the lower step surface 28A of the two-step flange portion 26A of the saddle member 7 comes into contact with the locking step surface 20 of the connection member 9, and further rotation of the connection member 9, ie, further Thus, the screwing of the connecting member 9 is substantially completed. The second packing 24 whose width is increased in this way makes the saddle member 7 and the connecting member 9 highly watertight.

図９および図１０には本発明の第３実施例が示されている。
本実施例にあっては、実施例１において使用された押圧部材２６を使用せず、それに代えて係止部材６の上縁を延長して上周面２７Ｂと、段部２８Ｂと、下面部２９Ｂとからなる押圧部２６Ｂを一体的に形成する。 9 and 10 show a third embodiment of the present invention.
In the present embodiment, the pressing member 26 used in the first embodiment is not used, and instead, the upper edge of the locking member 6 is extended to extend the upper peripheral surface 27B, the step portion 28B, and the lower surface portion. A pressing portion 26B composed of 29B is integrally formed.

上記構成にあっては、まず接続部材９の挿入部１８をサドル部材７に上側から内挿し、該係止部材９の押圧部２６Ｂの下面部２９Ｂは該サドル部材７の当接段部１６に懸架する。
この状態では該接続部材９のフランジ部２１の段面２３直下に嵌着されているパッキン２４は下方を解放されており、該パッキン２４の弾性緊縛力によって該接続部材９の外周に固定されている。したがって該接続部材９を回転させて該係止部材６に螺着して行く場合、当初は該接続部材９の回転にパッキン２４は全く干渉しない。
該接続部材９を該係止部材６に螺着して行くにつれ、実施例１と同様に該係止部材６は該接続部材９および該サドル部材７に対して相対的に引き上げられ、やがて該係止部材６の押圧部２６Ｂの上周面２７Ｂが該パッキン２４下部に当接し、該パッキン２４は該接続部材９のフランジ部２１の段面２３と該係止部材６の押圧部２６Ｂの上周面２７Ｂとの間で次第に挟圧されて厚みを縮小しかつ巾を拡大して該接続部材９外周面と該サドル部材７内周面とに圧接し、それに伴って該接続部材９の回転抵抗は漸増する。最終的には図１０に示すように該係止部材６の押圧部２６Ｂの段部２８Ｂが該接続部材９の係止段部２０に当接して該接続部材９の更なる回転、即ち更なる螺入が阻止されて該接続部材９の螺着が完了する。そしてこのようにして巾が拡大した第二パッキン２４によって該サドル部材７と該接続部材９との間が高度な水密状態にされている。 In the above configuration, first, the insertion portion 18 of the connecting member 9 is inserted into the saddle member 7 from above, and the lower surface portion 29B of the pressing portion 26B of the locking member 9 is connected to the contact step portion 16 of the saddle member 7. Suspend.
In this state, the packing 24 fitted immediately below the step surface 23 of the flange portion 21 of the connection member 9 is released below, and is fixed to the outer periphery of the connection member 9 by the elastic binding force of the packing 24. Yes. Therefore, when the connecting member 9 is rotated and screwed into the locking member 6, the packing 24 does not interfere with the rotation of the connecting member 9 at first.
As the connecting member 9 is screwed onto the locking member 6, the locking member 6 is pulled up relative to the connecting member 9 and the saddle member 7 in the same manner as in the first embodiment. The upper peripheral surface 27B of the pressing portion 26B of the locking member 6 contacts the lower portion of the packing 24, and the packing 24 is connected to the stepped surface 23 of the flange portion 21 of the connecting member 9 and the pressing portion 26B of the locking member 6. The connecting member 9 and the saddle member 7 are in pressure contact with the outer peripheral surface and the inner peripheral surface of the saddle member 7 by being gradually pinched with the peripheral surface 27B to reduce the thickness and expand the width. Resistance increases gradually. Finally, as shown in FIG. 10, the step portion 28B of the pressing portion 26B of the locking member 6 comes into contact with the locking step portion 20 of the connection member 9, and the connection member 9 is further rotated, that is, further. The screwing is prevented and the screwing of the connecting member 9 is completed. The second packing 24 whose width is increased in this way makes the saddle member 7 and the connecting member 9 highly watertight.

本発明は上記実施例にのみ限定されるものではなく、例えば該接続部材９の挿入部１８の内周部にねじ部１９を設け、該係止部材６の外周部にねじ溝１２を設け、該接続部材９を該係止部材６の外側から螺着してもよい。また該接続部材９は自在継手とされてもよい。   The present invention is not limited only to the above-described embodiment. For example, the screw portion 19 is provided on the inner peripheral portion of the insertion portion 18 of the connection member 9, and the screw groove 12 is provided on the outer peripheral portion of the locking member 6. The connecting member 9 may be screwed from the outside of the locking member 6. The connecting member 9 may be a universal joint.

更に、上記各実施例では、主管路である下水本管２に枝管路である取付管を接続する場合に接続支管１を使用するものとして説明したが、上記実施例以外、主管路であるますの立管（図示せず）に枝管路であるますの枝管（図示せず）を接続する場合に接続支管１を使用してもよい。   Further, in each of the above-described embodiments, the connection branch pipe 1 is used when the attachment pipe that is a branch pipe is connected to the sewage main pipe 2 that is the main pipe. The connecting branch pipe 1 may be used when connecting an additional branch pipe (not shown), which is a branch pipe line, to an additional vertical pipe (not shown).
