Description
本発明は、人孔用金蓋のパッキン、及び、このパッキンを構成する分割部材に関する。 The present invention relates to a packing for a manhole gold lid, and a split member constituting the packing.
人孔は、地下の下水道・暗渠・埋設された電気・通信ケーブルなどの管理（点検・修理・清掃・排気など）を目的として作業員が地上から出入りできるように地面にあけられた縦穴である。 A manhole is a vertical hole drilled in the ground so that workers can enter and exit the ground for the purpose of management (inspection, repair, cleaning, exhaust, etc.) of underground sewers, underdrains, buried electrical and communication cables, etc. .
この人孔は、一般にコンクリートで筒状に形成されており、出入口の開口（以下「出入口用開口」という）が地面で開口するように土中に埋設されている。この開口は、人孔用金蓋で閉じられるが、このための受枠が出入口用開口を形成する人孔の軸方向の一端側の縁部に設けられている。 The human hole is generally formed of concrete in a cylindrical shape, and is buried in the soil so that an opening at the entrance (hereinafter referred to as “entrance opening”) opens on the ground. This opening is closed by a manhole metal lid, and a receiving frame for this purpose is provided at the edge of one end side in the axial direction of the manhole forming the entrance / exit opening.
受枠は、筒形状に形成された側面受部と、この側面受部の内側側面に突設された底受部とを有している。この側面受部と底受部とで囲まれた部分に人孔用金蓋を挿入すると、人孔用金蓋が側面受部の内側に嵌り、出入口用開口が閉じられる（例えば、特許文献１参照）。 The receiving frame has a side receiving part formed in a cylindrical shape and a bottom receiving part protruding from the inner side surface of the side receiving part. When a human hole metal lid is inserted into a portion surrounded by the side receiving portion and the bottom receiving portion, the human hole gold lid fits inside the side receiving portion, and the entrance opening is closed (for example, Patent Document 1). reference).
人孔では、騒音等の防止のため、人孔用金蓋のパッキンが用いられることが多い。
この場合、人孔用金蓋のパッキンは底受部上に敷がれ、そのパッキン上に人孔用金蓋が載るようにして人孔用金蓋を受枠に嵌め込むことで、出入口用開口が閉じられる。
In human holes, packing for human holes is often used to prevent noise and the like.
In this case, the packing for the manhole cover is laid on the bottom receiving portion, and the manhole cover is placed on the packing so that the manhole cover is fitted into the receiving frame, thereby opening the entrance / exit. Is closed.
しかし、人孔や人孔用金蓋は設計誤差が大きく、設計通りの大きさにパッキンを製作しても、設計通りにパッキンが配置されないことがある。このように設計通りにパッキンが配置されないと、人孔用金蓋を受枠とが当たる確率が高くなるので、騒音抑制が狙い通りに行えない可能性があった。 However, the human hole and the human lid for the human hole have a large design error, and even if the packing is manufactured to the size as designed, the packing may not be arranged as designed. If the packing is not arranged as designed in this way, there is a possibility that noise suppression cannot be performed as intended because the probability that the mandrel lid will hit the receiving frame increases.
また、これに対応するため、特許文献１のようにパッキンを分割することも考えられる。これは、パッキンを分割すれば、設計誤差に応じてパッキンを配置することができるようになるためである。 In order to cope with this, it is also conceivable to divide the packing as in Patent Document 1. This is because if the packing is divided, the packing can be arranged according to the design error.
しかし、人孔用金蓋のパッキンは、経年使用により劣化した場合には取り替える必要がある。
このパッキンの取り替えは、人孔用金蓋をパッキンの取り替えが可能な高さまで持ち上げ、その持ち上げている間に古いパッキンを新しいパッキンに置き換える作業により行われる。
However, it is necessary to replace the packing for the manhole cover when it has deteriorated due to aging.
The replacement of the packing is performed by lifting the manhole hole lid to a height at which the packing can be replaced, and replacing the old packing with a new packing while the packing is being lifted.
このような場合、パッキンが分割されていると、作業員は、その分割されている数だけ、人孔と、持ち上げている人孔用金蓋との間に腕を差し入れなければならなくなり、工程数が多く、しかも危険であった。 In such a case, when the packing is divided, the worker has to insert his / her arms between the manhole and the lifted manhole cover by the number of divided pieces, It was a lot and dangerous.
本発明は、人孔が設計通りの大きさでなかった場合でも、その大きさに合わせて柔軟に径を変えることができ、しかも、少ない工程でパッキンの取り替えが可能な人孔用金蓋のパッキン、及び、このパッキンを構成する分割部材を提供することを目的とする。 In the present invention, even when the human hole is not the size as designed, the diameter of the human hole can be changed flexibly in accordance with the size of the hole and the packing can be replaced with fewer steps. It is an object of the present invention to provide a packing and a dividing member constituting the packing.
請求項１に記載の人孔用金蓋のパッキンは、
人孔用金蓋と人孔用金蓋の受枠との間に設置される人孔用金蓋のパッキンにおいて、組み合わせると円形状となる分割部材であって、円弧形状に形成されるとともに、円の軸方向に沿った厚みに対して円の径方向に沿った幅が広い形状に形成された複数の分割部材と、
分割部材の円弧の第１端側の厚みをなす面から突設された雄部と、雄部に形成された引掛孔であって、円形状の軸方向に垂直な面に形成された引掛孔と、分割部材の円弧の第２端側の厚みをなす面に設けられ、雄部を挿入可能な雌部と、
分割部材の幅をなす面である幅面のうち、分割部材の内部に雌部が形成された部分に形成され、雌部に通じる孔部と、孔部の底をなす面から、孔部の開口側に向かって突設され、雄部を雌部に挿入する挿入方向に沿った長さが、引掛孔に比べ短く形成された突起部と、
を備えるものである。
The packing for the mandrel gold lid according to claim 1,
In the packing for the manhole cover, which is installed between the manhole cover and the receiving frame of the manhole cover, it is a divided member that becomes a circular shape when combined, and is formed into an arc shape and a circle. A plurality of divided members formed in a shape having a wide width along the radial direction of the circle with respect to the thickness along the axial direction of
A male part projecting from the surface forming the thickness of the first end side of the arc of the divided member, and a hooking hole formed in the male part, the hooking hole being formed in a circular surface perpendicular to the axial direction And a female part that is provided on the surface forming the thickness of the second end side of the arc of the divided member and into which the male part can be inserted,
Of the width surface that is the width of the divided member, the hole portion is formed from the hole portion that is formed in the portion where the female portion is formed inside the divided member and communicates with the female portion and the surface that forms the bottom of the hole portion. A protrusion that protrudes toward the side and has a length along the insertion direction in which the male part is inserted into the female part, and is shorter than the hooking hole;
Is provided.
このような構成によると、隣接する分割部材の雄部を雌部に挿入した場合、雄部に設けられた引掛孔が、雌部に設けられた突起部に引っ掛かる。このとき、突起部の長さであって、雄部を雌部に挿入する挿入方向に沿った長さが、引掛孔に比べて短いので、分割部材を円状に組み合わせても、柔軟に径を変えることができる。 According to such a configuration, when the male part of the adjacent divided member is inserted into the female part, the hooking hole provided in the male part is hooked on the protrusion provided in the female part. At this time, since the length of the protruding portion along the insertion direction in which the male portion is inserted into the female portion is shorter than that of the hooking hole, the diameter can be flexibly adjusted even if the divided members are combined in a circular shape. Can be changed.
そのため、この人孔用金蓋のパッキンは、人孔が設計通りの大きさでなかった場合でも、その大きさに合わせて柔軟に径を変えて、人孔受枠等に設置することができる。
また、このような構成によると、パッキンは、雄部を雌部に挿入して、引掛孔を突起部に引っ掛ければ、複数の分割部材をはずれないように組み合わせることができるので、事前に円形状に組み立てておくことができる。
Therefore, even when the human hole is not the size as designed, the packing for the human hole gold lid can be flexibly changed in diameter according to the size and installed in the human hole receiving frame or the like.
Further, according to such a configuration, the packing can be combined so that a plurality of divided members cannot be detached by inserting the male part into the female part and hooking the hooking hole on the protruding part. Can be assembled in shape.
そのため、このパッキンは、経年劣化等により取り替えるときでも、一度の工程で取り替えることができる。
また、このパッキンは、円形に組み合わせると、ひとつの分割部材を持っても他の分割部材がはずれない。そのため、このパッキンは、円形に組み合わせても円形を保つことができるので、パッキンの入替作業時などにひとつの分割部材を持って作業をしても、他の分割部材がはずれることがない。
Therefore, even when the packing is replaced due to aging or the like, it can be replaced in a single process.
Moreover, when this packing is combined in a circle, even if it has one divided member, the other divided members do not come off. Therefore, even if this packing is combined in a circle, the circular shape can be maintained. Therefore, even if the work is carried with one divided member at the time of replacing the packing, the other divided members will not come off.
突起部は、請求項２に記載したように、雌部が第２端の厚みをなす面で開口する挿入口の側に向かって先細な形状をなす傾斜部を有する形状に形成してもよい。
このような構成によると、パッキンは、分割部材同士を組み合わせるとき、雄部を雌部に挿入するだけで、雄部がこの傾斜部に乗り上げた後、引掛孔が突起部に引っ掛かるので、分割部材同士を簡単に組み合わせることができる。
As described in claim 2, the protruding portion may be formed in a shape having an inclined portion that forms a tapered shape toward the side of the insertion opening where the female portion opens at the surface forming the thickness of the second end. .
According to such a configuration, when the packing parts are combined with each other, since the male part rides on the inclined part only after the male part is inserted into the female part, the hooking hole is hooked on the protruding part. You can easily combine them.
人孔用金蓋のパッキンは、請求項３に記載したように、孔部が、上下の幅面に設けられ、かつ、第２端側から第１端の側に向かって交互に形成されていてもよい。
この場合、孔部は上下の幅面に千鳥に配置される。このように形成したほうが設計上、製造しやすいからである。
As described in claim 3, the packing for the human lid for the manhole is provided with holes in the upper and lower width surfaces and alternately formed from the second end side to the first end side. Also good.
In this case, the holes are staggered on the upper and lower width surfaces. This is because it is easier to manufacture by design.
尚、請求項４に記載したように、突起部は、最も第１端部よりの孔部に形成されていてもよいが、これに限られるものではない。
人孔用金蓋パッキンは、請求項５に記載したように、人孔用金蓋を受枠に嵌めたときに、人孔用金蓋の外周側面と、受枠の内周側面とに挟まれる部分であって、分割部材の外側の円弧をなす部分から突設された鍔部を備えるようにしてもよい。
In addition, as described in Claim 4, although the projection part may be formed in the hole part from the 1st end most, it is not restricted to this.
As described in claim 5, when the manhole cover is inserted into the receiving frame, the manhole cover is sandwiched between the outer peripheral side surface of the manhole cover and the inner peripheral surface of the receiving frame. And you may make it provide the collar part protruded from the part which makes the circular arc of the outer side of a division member.
このような構成によると、人孔用金蓋パッキンは、人孔用金蓋と、受枠と間にできる隙間をより多く埋めることができるので、人孔の出入口用開口を人孔用金蓋で確実に閉じることができる。 According to such a configuration, the manhole metal lid packing can fill more gaps between the manhole metal lid and the receiving frame. It can be closed securely.
以下に本発明の例示的な実施形態について図面を参照しながら説明する。
本実施形態の人孔用金蓋のパッキン１は、図１に示すように、組み合わせると円形状となる複数の分割部材３を順次連結して組み合わせたものである。
Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the packing 1 for a manhole cover according to this embodiment is formed by sequentially connecting and combining a plurality of divided members 3 that are circular when combined.
分割部材３は、本体部３０と、鍔部３１とを有している。本体部３０は、円弧形状に形成されるとともに、円の軸方向に沿った厚みに対して円の径方向に沿った幅が広い形状に形成されている。鍔部３１は、分割部材３の外側の円弧をなす部分から、本体部３０の幅方向に沿った側面に対し略垂直に立設されている。このため分割部材３は、本体部３０がなす円弧に垂直な断面形状が、図２に示すように、略Ｌ字となるように形成される。 The dividing member 3 has a main body portion 30 and a flange portion 31. The main body 30 is formed in a circular arc shape, and is formed in a shape having a wider width along the radial direction of the circle than the thickness along the axial direction of the circle. The flange 31 is erected substantially perpendicularly to the side surface along the width direction of the main body 30 from a portion forming an arc on the outer side of the dividing member 3. For this reason, the dividing member 3 is formed so that the cross-sectional shape perpendicular to the arc formed by the main body 30 is substantially L-shaped as shown in FIG.
このように形成された人孔用金蓋のパッキン１を取り付けた場合、本体部３０は、人孔用金蓋９０を受枠９１に嵌めたときに、人孔用金蓋９０の底面９００と、受枠９１の底受部９１０との間に挟まれる。そして、鍔部３１は、人孔用金蓋９０の周囲側面９０１と、受枠９１の側面受部９１１との間に挟まれる。 When the packing 1 of the human hole gold lid formed in this way is attached, the main body 30 is configured such that when the human hole gold lid 90 is fitted into the receiving frame 91, the bottom surface 900 of the human hole gold lid 90; It is sandwiched between the bottom receiving portion 910 of the receiving frame 91. And the collar part 31 is pinched | interposed between the surrounding side surface 901 of the gold lid 90 for manholes, and the side surface receiving part 911 of the receiving frame 91. FIG.
図３に示すように、分割部材３の円弧の２つの端部のうち第１端側の厚みをなす面３００には、舌片形状に形成された雄部４０が突設される。
この雄部４０は、パッキン１が形成する円の軸方向に垂直な面４００を有しており、この面４００を貫通して、一対の引掛孔４１が形成されている。
As shown in FIG. 3, a male portion 40 formed in the shape of a tongue piece protrudes from a surface 300 forming a thickness on the first end side of two end portions of the arc of the dividing member 3.
The male part 40 has a surface 400 perpendicular to the axial direction of the circle formed by the packing 1, and a pair of hooking holes 41 are formed through the surface 400.
これら引掛孔４１は、面３００に沿った方向であって、面３００が形成される部分の本体部３０の幅方向に沿って並べて形成されている。
図４に示すように、分割部材３の円弧の２つの端部のうち第２端側の厚みをなす面３０１には、雄部４０を挿入可能な孔部である雌部５０が形成されている。
These hooking holes 41 are formed along the width direction of the main body portion 30 in the direction along the surface 300 and where the surface 300 is formed.
As shown in FIG. 4, a female portion 50, which is a hole into which the male portion 40 can be inserted, is formed on the surface 301 that forms the thickness on the second end side of the two end portions of the arc of the dividing member 3. Yes.
分割部材３の幅をなす面である幅面３０２のうち、分割部材３の内部に雌部５０が形成された部分には、雌部５０に通じる孔部３２が形成されている。この孔部３２は、上下の幅面３０２に設けられ、かつ、第２端側から第１端部側に向かって交互に形成されている（図５参照）。 In the width surface 302 which is a surface forming the width of the dividing member 3, a hole portion 32 communicating with the female portion 50 is formed in a portion where the female portion 50 is formed inside the dividing member 3. The holes 32 are provided on the upper and lower width surfaces 302 and are alternately formed from the second end side toward the first end side (see FIG. 5).
これら複数の孔部３２のうち、最も第１端側より（面３０１から見て最も遠い位置）に位置する孔部３２には、その孔部３２の底面３２０から突設された一対の突起部５１が突設されている。 Among the plurality of holes 32, a pair of protrusions projecting from the bottom surface 320 of the hole 32 is provided in the hole 32 positioned farthest from the first end side (a position farthest from the surface 301). 51 is protrudingly provided.
これら突起部５１は、頂部が、これら突起部５１が形成された孔部３２の開口面に届く高さに形成されている。そして、これら突起部５１は、雄部４０の雌部５０への挿入方向に対し垂直な方向であって、幅面３０２に平行な方向に沿って並べられている。 The protrusions 51 are formed at a height such that the top reaches the opening surface of the hole 32 in which the protrusions 51 are formed. The protrusions 51 are arranged along a direction perpendicular to the insertion direction of the male part 40 into the female part 50 and parallel to the width surface 302.
また、これら突起部５１は、雄部４０を雌部５０に挿入する挿入方向に沿った長さが、引掛孔４１に比べ短い形状に形成されている。また、これら突起部５１には、雌部５０が面３０１で開口する挿入口の側に向かって先細な形状をなす傾斜部５２が形成されている。 Further, the protrusions 51 are formed in a shape shorter in length along the insertion direction in which the male part 40 is inserted into the female part 50 than the hooking hole 41. In addition, the protruding portions 51 are formed with inclined portions 52 having a tapered shape toward the side of the insertion opening in which the female portion 50 opens at the surface 301.
次に、図５を用いて、分割部材３の連結について説明する。
隣接する分割部材３を連結するため、ひとつの分割部材３の雄部４０をもうひとつの分割部材３の雌部５０に挿入する。すると、雄部４０に設けられた引掛孔４１が、雌部５０に設けられた突起部５１に引っ掛かる。このとき、突起部５１は、雄部４０を雌部５０に挿入する挿入方向に沿った長さが、引掛孔４１に比べて短いので、分割部材３を円状に組み合わせてパッキン１を構成しても、パッキン１の径を柔軟に変更することができる。
Next, the connection of the divided members 3 will be described with reference to FIG.
In order to connect the adjacent divided members 3, the male part 40 of one divided member 3 is inserted into the female part 50 of the other divided member 3. Then, the hooking hole 41 provided in the male part 40 is hooked on the protruding part 51 provided in the female part 50. At this time, since the protrusion 51 has a shorter length along the insertion direction in which the male part 40 is inserted into the female part 50 than the hooking hole 41, the split member 3 is combined in a circular shape to constitute the packing 1. Even so, the diameter of the packing 1 can be flexibly changed.
以上から、この人孔用金蓋のパッキン１は、人孔が設計通りの大きさでなかった場合でも、その大きさに合わせて柔軟に径を変えて、人孔の受枠９１等に設置することができる。 From the above, even if the manhole is not the size as designed, the manhole cover 1 is installed on the manhole receiving frame 91 or the like by changing its diameter flexibly according to the size. be able to.
また、このような構成によると、人孔用金蓋のパッキン１は、雄部４０を雌部５０に挿入して、引掛孔４１を突起部５１に引っ掛ければ、複数の分割部材３をはずれないように組み合わせることができるので、事前に円形状に組み立てておくことができる。 Further, according to such a configuration, the packing 1 of the manhole cover can be detached from the plurality of divided members 3 by inserting the male part 40 into the female part 50 and hooking the hooking hole 41 on the protruding part 51. Since they can be combined so that they do not exist, they can be assembled into a circular shape in advance.
そのため、この人孔用金蓋のパッキン１は、経年劣化等により取り替えるときでも、一度の工程で取り替えることができる。
また、人孔用金蓋のパッキン１は、突起部５１が傾斜部５２を備えているので、分割部材３同士を組み合わせるとき、雄部４０を５０に挿入するとき、雄部４０がこの傾斜部５２に乗り上げた後、引掛孔４１が突起部５１に引っ掛かる。すると、連結部材３同士が連結されるので、この人孔用金蓋のパッキン１は、分割部材３同士を簡単に組み合わせることができる
また、人孔用金蓋のパッキン１は、孔部３２が、上下の幅面３０２に、第２端側から前記第部側に向かって交互（いわゆる千鳥）に形成されている。このように形成したほうが設計上、製造しやすいからである。
For this reason, the packing 1 for the manhole cover can be replaced in a single process even when it is replaced due to deterioration over time.
Moreover, since the protrusion 51 is equipped with the inclination part 52, the male part 40 is this inclination part when inserting the male part 40 in 50, since the projection part 51 is equipped with the inclination part 52. After getting on 52, the hooking hole 41 is hooked on the protrusion 51. Then, since the connecting members 3 are connected to each other, the packing 1 for the manhole cover can be easily combined with the divided members 3. The upper and lower width surfaces 302 are alternately (so-called staggered) from the second end side toward the first part side. This is because it is easier to manufacture by design.
また、人孔用金蓋のパッキン１は、鍔部３１を備えているので、人孔用金蓋９０と、受枠９１と間にできる隙間を確実に埋めることができる。そのため、人孔用金蓋のパッキン１は、人孔の出入口用開口を人孔用金蓋９０で確実に閉じることができる。
［他の実施形態］
以上、実施形態について説明したが、特許請求の範囲に記載された発明は、上記実施形態に限定されることなく、種々の形態を採り得ることは言うまでもない。
Further, since the packing 1 for the manhole cover is provided with the flange portion 31, the gap formed between the manhole cover 90 and the receiving frame 91 can be reliably filled. Therefore, the packing 1 for the manhole cover can securely close the opening for the entrance and exit of the manhole with the manhole cover 90.
