Description
本発明は、便器の排水口と排水管とを接続するための床フランジ、排水ソケットなどの排水管接続部材に関する。 The present invention relates to a drain pipe connecting member such as a floor flange and a drain socket for connecting a drain port of a toilet and a drain pipe.
便器と排水管とを床フランジによって接続する従来例（特開平９−２９１５８２の従来技術の欄）について第３図を参照して説明する。 A conventional example in which a toilet bowl and a drain pipe are connected by a floor flange (the column of the prior art in JP-A-9-291582) will be described with reference to FIG.
トイレルームの床１に排水管２が配設されている。この排水管２の上端に床フランジ３が装着されている。この床フランジ３は、排水管２内に挿入される筒部３ａと、該筒部３ａの上端に連なる鍔部３ｂを有する。この筒部３ａの外周面と排水管２の内周面とは接着剤によって接着されている。
この床フランジ３に便器４の座枠５が被さっており、該座枠５と床フランジ３との間に粘性ガスケット６が介在されている。この粘性ガスケット６は、非加硫ブチルゴム等の粘塑性及び粘着性を有した素材よりなり、フランジ３及び座枠５の排水口７の周囲部にそれぞれ水密的に密着している。
A drain pipe 2 is disposed on the floor 1 of the toilet room. A floor flange 3 is attached to the upper end of the drain pipe 2. The floor flange 3 has a cylindrical portion 3a inserted into the drain pipe 2 and a flange portion 3b connected to the upper end of the cylindrical portion 3a. The outer peripheral surface of the cylindrical portion 3a and the inner peripheral surface of the drain pipe 2 are bonded with an adhesive.
A seat frame 5 of the toilet 4 is covered with the floor flange 3, and a viscous gasket 6 is interposed between the seat frame 5 and the floor flange 3. The viscous gasket 6 is made of a material having viscoplasticity and adhesiveness such as non-vulcanized butyl rubber, and is in close contact with the peripheral portions of the flange 3 and the drainage port 7 of the seat frame 5 respectively.
床フランジ３と座枠５とはＴボルト８及びナット９によって連結され、これにより便器４が固定される。Ｔボルト８は、鍔部３ｂに設けられたボルト挿通孔３ｃに下から上に向って挿通されている。
The floor flange 3 and the seat frame 5 are connected by a T-
この床フランジ３の筒部３ａは、排水管２に内嵌し易くするために下方に向って縮径するテーパ形状となっている。 The cylindrical portion 3 a of the floor flange 3 has a tapered shape that is reduced in diameter toward the bottom in order to easily fit into the drain pipe 2.
排水管２と筒部３ａとを接合する場合、筒部３ａの外周面に接着剤を塗布してから筒部３ａを排水管２内に差し込む。 When joining the drain pipe 2 and the cylinder part 3 a, an adhesive is applied to the outer peripheral surface of the cylinder part 3 a, and then the cylinder part 3 a is inserted into the drain pipe 2.
床フランジの代わりに排水ソケットを用いて便器と排水管とを接続することも周知である（例えば特許文献２〜５）。
上記排水管２は、塩化ビニル（塩ビ）製であり、その外径及び肉厚はＪＩＳによって規定されている。この肉厚はその範囲が規定されているため、塩ビ管の内径は所定の範囲においてバラツクことになる。 The drain pipe 2 is made of vinyl chloride (vinyl chloride), and its outer diameter and thickness are defined by JIS. Since the thickness of the wall thickness is regulated, the inner diameter of the PVC pipe varies within a predetermined range.
このように排水管２の口径にバラツキがあっても、床フランジ３の筒部３ａは排水管２に対し、きつく且つ十分に深く差し込まれる必要がある。仮に筒部３ａが過度に小径であると、鍔部３ｂが床１に当接するまで筒部３ａが排水管２に差し込まれても、筒部３ａの外周と排水管２の内周との間に隙間が存在し、漏水や臭気漏れが生じるおそれがある。 Thus, even if the diameter of the drain pipe 2 varies, the cylindrical portion 3a of the floor flange 3 needs to be inserted into the drain pipe 2 tightly and sufficiently deeply. If the cylinder portion 3a has an excessively small diameter, even if the cylinder portion 3a is inserted into the drain pipe 2 until the collar portion 3b contacts the floor 1, the gap between the outer circumference of the cylinder portion 3a and the inner circumference of the drain pipe 2 There is a risk of water leakage and odor leakage.
逆に、筒部３ａが過度に大径であると、筒部３ａを排水管２に差し込んでいる途中でそれ以上筒部３ａを排水管２に押し込むことができなくなり、鍔部３ｂが床１から浮いてしまうことになる。 On the contrary, if the cylindrical portion 3a has an excessively large diameter, the cylindrical portion 3a cannot be pushed further into the drainage pipe 2 while the cylindrical portion 3a is being inserted into the drainage pipe 2, and the flange portion 3b becomes the floor 1 Will float from.
また、テーパーを過度につけて許容範囲を広くすると、筒部下端が必要以上に絞られることになり、排水性能に影響を与える恐れもでてくる。 Further, if the taper is excessively applied to widen the allowable range, the lower end of the cylindrical portion will be narrowed more than necessary, and the drainage performance may be affected.
本発明は、このような従来技術に鑑みて創案されたものであり、筒部が排水管に十分に深く且つ十分にきつく内嵌するように構成された床フランジ、排水ソケットなどの排水管接続部材を提供することを目的とする。 The present invention was devised in view of such prior art, and is connected to drain pipes such as floor flanges, drain sockets, etc., in which the cylindrical portion is sufficiently deep and sufficiently fitted into the drain pipe. An object is to provide a member.
請求項１の排水管接続部材は、トイレルームの床の排水管に内嵌する筒部と、該筒部の上端に連なっており、該床の上面に載置される鍔部とを有してなり、該筒部は、外径が下端に向って縮径するテーパ形状となっている排水管接続部材において、該筒部の上部は、下側よりもテーパ角が大きい急テーパ部となっており、該筒部の長さが２５〜６０ｍｍであり、該急テーパ部の長さが筒部の５〜３０％であり、該急テーパ部よりも下側のテーパ角が１〜３゜であり、該急テーパ部のテーパ角がそれよりも１〜５゜大きいことを特徴とするものである。 The drain pipe connecting member according to claim 1 has a cylinder part fitted in the drain pipe of the floor of the toilet room, and a flange part connected to the upper end of the cylinder part and placed on the upper surface of the floor. In the drain pipe connecting member having a tapered shape whose outer diameter is reduced toward the lower end, the upper portion of the cylindrical portion is a steeply tapered portion having a larger taper angle than the lower side. The length of the cylindrical portion is 25 to 60 mm, the length of the steeply tapered portion is 5 to 30% of the cylindrical portion, and the taper angle below the steeply tapered portion is 1 to 3 °. And the taper angle of the steep taper portion is 1 to 5 ° larger than that.
請求項２の排水管接続部材は、請求項１において、塩化ビニル製であることを特徴とするものである。 Drainage pipe connecting member according to claim 2 is characterized in that in claim 1 Oite, it is made of vinyl chloride.
本発明の排水管接続部材は、上部がテーパ角が大きいものとなっており、下側がテーパ角が小さいものとなっている。従って、テーパ角が小さい下側部分については、排水管に確実に差し込むことができるように比較的小径としておき、テーパ角が大きい筒部上部（急テーパ部）を排水管の内周面にきつく嵌めるよう構成することができる。 In the drain pipe connecting member of the present invention, the upper portion has a large taper angle, and the lower side has a small taper angle. Therefore, the lower portion with a small taper angle is set to have a relatively small diameter so that it can be surely inserted into the drain pipe, and the upper part of the cylinder part (steep taper part) with a large taper angle is tightly attached to the inner peripheral surface of the drain pipe. It can be configured to fit.
筒部に接着剤を塗布すると、筒部の外周面が滑り易い状態となり、筒部の外周面が排水管の内周面に当った後も、さらに筒部を排水管内に押し込むことができ、筒部を排水管内に十分に奥深く押し込むことができる。 When the adhesive is applied to the tube portion, the outer peripheral surface of the tube portion becomes slippery, and even after the outer peripheral surface of the tube portion hits the inner peripheral surface of the drain pipe, the cylinder portion can be further pushed into the drain pipe, The tube portion can be pushed deeply into the drain pipe.
なお、排水管は一般に塩ビ製であるので、本発明の床フランジも塩ビ製とされることが好ましい。塩ビ用接着剤を塩ビ製床フランジの筒部外周面に塗布すると、接着剤中の溶剤成分によって筒部外周面の表層が溶け、筒部が排水管内に押し込まれ易くなる。 Since the drain pipe is generally made of polyvinyl chloride, the floor flange of the present invention is also preferably made of vinyl chloride. When the adhesive for vinyl chloride is applied to the outer peripheral surface of the cylindrical portion of the floor flange made of polyvinyl chloride, the surface layer of the outer peripheral surface of the cylindrical portion is melted by the solvent component in the adhesive, and the cylindrical portion is easily pushed into the drain pipe.
以下、図面を参照して実施の形態について説明する。なお、以下の説明において、排水管の口径が大き目又は小さ目とは、ＪＩＳ規格の許容範囲内において口径が大きい又は小さいことを表す。 Hereinafter, embodiments will be described with reference to the drawings. In the following description, the larger or smaller diameter of the drain pipe means that the diameter is larger or smaller within the allowable range of the JIS standard.
第１図は実施の形態に係る床フランジの断面図、第２図はこの床フランジと排水管との接続途中の断面図である。 FIG. 1 is a cross-sectional view of a floor flange according to an embodiment, and FIG. 2 is a cross-sectional view in the middle of connection between the floor flange and a drain pipe.
この床フランジ１０は、塩ビ製であり、前記第３図の床フランジと同様に、筒部２０と、この筒部２０の上端に連なる鍔部３０とを有している。鍔部３０には、床フランジ１０を床に留め付けるための皿ビスの挿通孔３１のほか、Ｔボルトを挿通させるためのボルト挿通孔（第３図参照。第１，２図では図示略。）が設けられている。
The floor flange 10 is made of polyvinyl chloride, and has a cylindrical portion 20 and a flange portion 30 connected to the upper end of the cylindrical portion 20 in the same manner as the floor flange of FIG. In addition to the countersunk
筒部２０は、下方に向って徐々に外径が小さくなるテーパ形状である。 The cylindrical portion 20 has a tapered shape in which the outer diameter gradually decreases downward.
この実施の形態では、筒部２０の上部は、比較的テーパ角が大きい急テーパ部２２であり、この急テーパ部２２よりも下側が比較的テーパ角の小さい緩テーパ部２１となっている。この筒部２０の長さＬは２５〜６０ｍｍ特に３０〜５０ｍｍ程度が好ましい。Ｌが２５ｍｍよりも小さいと、筒部２０の排水管２への差し込み長さが短くなり、漏水や臭気漏れが生じるおそれがある。一方、Ｌが６０ｍｍよりも長いと、筒部２０を排水管２に押し込みにくくなるおそれがある。 In this embodiment, the upper portion of the cylindrical portion 20 is a steep taper portion 22 having a relatively large taper angle, and the lower side of the steep taper portion 22 is a gentle taper portion 21 having a relatively small taper angle. The length L of the cylindrical portion 20 is preferably about 25 to 60 mm, particularly about 30 to 50 mm. When L is smaller than 25 mm, the length of insertion of the tubular portion 20 into the drain pipe 2 is shortened, and there is a possibility that water leakage or odor leakage may occur. On the other hand, if L is longer than 60 mm, it may be difficult to push the cylindrical portion 20 into the drain pipe 2.
筒部上部を構成する急テーパ部２２の長さＬ２は、Ｌの５〜３０％特に１０〜２０％程度が好ましい。Ｌ２がＬの５％よりも小さいと、口径が大き目の排水管２の場合に漏水や臭気漏れが生じるおそれがある。Ｌ２がＬの３０％よりも長いと、口径が小さ目の排水管２の場合、筒部２０を排水管２に押し込みにくくなるおそれがある。 The length L 2 of the steep tapered portion 22 which constitutes a cylindrical portion upper, 5-30% in particular 10 to 20% of the L is preferred. When L 2 is less than 5% of L, diameter is likely to leak or odor leakage occurs in the case of larger drainage pipe 2. When L 2 is longer than 30% of L, when the diameter of the drainage pipe 2 of smaller, it may become difficult to push the tubular portion 20 to drain 2.
緩テーパ部２１のテーパ角は１〜３゜特に１〜１．５゜が好適であり、急テーパ部２２のテーパ角はそれよりも１〜５゜特に１．５〜４゜大きいことが好適である。緩テーパ部２１のテーパ角が１゜よりも小さいと、筒部２０を口径が小さ目の排水管２に押し込みにくくなるおそれがある。一方、緩テーパ部２１のテーパ角が３゜よりも大きいと、口径が大き目の排水管２の場合、接着面積が小さくなり、漏水や臭気漏れが生じるおそれがある。 The taper angle of the gentle taper portion 21 is preferably 1 to 3 °, particularly 1 to 1.5 °, and the taper angle of the steep taper portion 22 is preferably 1 to 5 °, particularly 1.5 to 4 ° larger than that. It is. If the taper angle of the gentle taper portion 21 is smaller than 1 °, it may be difficult to push the tube portion 20 into the drain pipe 2 having a small diameter. On the other hand, when the taper angle of the gentle taper portion 21 is larger than 3 °, in the case of the drain pipe 2 having a large diameter, the adhesion area becomes small, and there is a possibility that water leakage or odor leakage occurs.
急テーパ部２２のテーパ角が上記範囲よりも小さいと、口径が大き目の排水管２の場合に、筒部２０の全体が排水管２に差し込まれても排水管２の内周と筒部２０の上部との間に隙間が残り、漏水や臭気漏れが生じるおそれがある。また、急テーパ部２２のテーパ角が上記範囲よりも大きいと、口径が小さ目の排水管２の場合に、筒部２０の押し込み途中で、それ以上、筒部２０を排水管２内に押し込むことができなくなり、鍔部３０が床から浮くようになるおそれがある。 When the taper angle of the steep taper portion 22 is smaller than the above range, in the case of the drain pipe 2 having a large diameter, the inner circumference of the drain pipe 2 and the cylinder portion 20 even if the entire cylinder portion 20 is inserted into the drain pipe 2. There is a possibility that a gap may remain between the upper part of the water and leakage or odor leakage may occur. Further, when the taper angle of the steep taper portion 22 is larger than the above range, in the case of the drain pipe 2 having a small diameter, the cylinder section 20 is pushed further into the drain pipe 2 while the cylinder section 20 is being pushed. May not be possible, and the heel part 30 may float from the floor.
筒部２０の下端の直径（外径）Ｄｍｉｎと上端の直径（外径）Ｄｍａｘとの差は、１〜４ｍｍ特に１．５〜３ｍｍであることが好ましい。 The difference between the lower end diameter (outer diameter) Dmin and the upper end diameter (outer diameter) Dmax of the cylindrical portion 20 is preferably 1 to 4 mm, particularly preferably 1.5 to 3 mm.
このように構成された床フランジも、前記第３図の床フランジ３と同様に、筒部２０に接着剤を塗布して該筒部２０を排水管２に押し込むことにより排水管２と接合される。 Similarly to the floor flange 3 of FIG. 3, the floor flange configured in this way is joined to the drain pipe 2 by applying an adhesive to the cylinder portion 20 and pushing the cylinder portion 20 into the drain pipe 2. The
筒部２０の長さやテーパ角が上記の範囲にあると、ＪＩＳで許容される範囲の口径の排水管であれば、筒部２０の排水管２への差し込み途中で筒部２０の外周が排水管２の内周に当接し、しかもそれ以降も筒部２０をさらに深く排水管２に押し込むことができる。 If the length and taper angle of the cylindrical portion 20 are within the above ranges, the outer periphery of the cylindrical portion 20 is drained while the cylindrical portion 20 is being inserted into the drainage pipe 2 as long as the drainage pipe has a diameter within the range allowed by JIS. The cylindrical portion 20 can be pushed deeper into the drainage pipe 2 after contacting the inner periphery of the pipe 2 and thereafter.
即ち、排水管２の口径が大き目であったとしても、筒部２０の上部の急テーパ部２２に排水管２の上端内周が当たり、筒部２０と排水管２との間を水密的、気密的に封じることができる。 That is, even if the diameter of the drain pipe 2 is large, the inner periphery of the upper end of the drain pipe 2 hits the steep taper portion 22 at the upper part of the cylinder section 20, and the space between the cylinder section 20 and the drain pipe 2 is watertight. Can be sealed airtight.
また、排水管２の口径が小さ目であったとしても、緩テーパ部２１をこの排水管２内に差し込むことができる。この差し込み途中で排水管２の上端の内周が筒部２０の外周面に第２図の如く当接する。このとき、排水管２の上端から鍔部３０までの長さＰがある程度になっていれば、筒部２０を排水管２に十分に奥深くまで差し込み、鍔部３０をトイレルームの床に当接させることが可能となる。 Even if the diameter of the drain pipe 2 is small, the gentle taper portion 21 can be inserted into the drain pipe 2. In the middle of this insertion, the inner periphery of the upper end of the drain pipe 2 contacts the outer peripheral surface of the cylindrical portion 20 as shown in FIG. At this time, if the length P from the upper end of the drainage pipe 2 to the collar part 30 is a certain amount, the cylinder part 20 is inserted deeply into the drainage pipe 2 and the collar part 30 is brought into contact with the floor of the toilet room. It becomes possible to make it.
即ち、前述の通り、塩ビ製の床フランジの場合、塩ビ用接着剤を筒部２０の外周面に塗布すると、接着剤中の溶剤成分によって筒部２０の外周面の表層が溶ける。そのため、排水管２の上端内周が筒部２０の外周に当った後でも、床フランジ１０を強く押すと、筒部２０が排水管２内に押し込まれる。このように排水管２の上端内周と筒部２０の外周とが当った後でも鍔部３０が床に当接するまで筒部２０を排水管２内に押し込むことが可能である。なお、この押し込み深さは、テーパーの傾斜によって異なるが、２０ｍｍ以下であることが好ましい。 That is, as described above, in the case of a PVC floor flange, when a vinyl chloride adhesive is applied to the outer peripheral surface of the cylindrical portion 20, the surface layer of the outer peripheral surface of the cylindrical portion 20 is melted by the solvent component in the adhesive. Therefore, even after the inner periphery of the upper end of the drain pipe 2 hits the outer periphery of the cylinder part 20, if the floor flange 10 is pressed strongly, the cylinder part 20 is pushed into the drain pipe 2. Thus, even after the inner periphery of the upper end of the drainage pipe 2 and the outer circumference of the cylinder part 20 hit each other, the cylinder part 20 can be pushed into the drainage pipe 2 until the flange part 30 comes into contact with the floor. In addition, although this indentation depth changes with inclinations of a taper, it is preferable that it is 20 mm or less.
上記実施の形態では、排水管接続部材は床フランジであるが、排水ソケットであってもよい。 In the above embodiment, the drain pipe connecting member is a floor flange, but may be a drain socket.
