【０００１】[0001]
この考案は鋼管杭の防食テープ被覆工法用保護カバーに関するものである。 The present invention relates to a protective cover for a steel pipe pile for use with an anticorrosion tape coating method.
【０００２】[0002]
鋼管杭の防食テープ被覆工法を図４，図５について説明する。図において、１ は鋼管杭、２は鋼管杭１の表面に施工された防食ペースト、３は防食ペースト２ の上から鋼管杭１の表面に巻収された防食テープ、４は防食テープ３の上から鋼 管杭１の表面に被嵌せしめられる保護カバーで、筒方向に沿う割目４１を有する 筒カバー４ａと、この筒カバー４ａの割目４１の両端側に対向状に設けられる両 締付片４ｂと、この両締付片４ｂにそれぞれ取付けられる補強アングル４ｃとで 構成されている。５は保護カバー４を締付けて装着するボルトナットで、両締付 片４ｂおよび補強アングル４ｃの両孔４２に貫挿される。なお、図中６はワッシ ャ、７はカバー当板である。 A method of coating a steel pipe pile with an anticorrosion tape will be described with reference to FIGS. 4 and 5. In the figure, 1 is a steel pipe pile, 2 is an anticorrosion paste applied on the surface of the steel pipe pile 1, 3 is an anticorrosion tape wound from the anticorrosion paste 2 on the surface of the steel pipe pile 1, and 4 is an anticorrosion tape 3. Is a protective cover that is fitted onto the surface of the steel pipe pile 1, and has a tubular cover 4a having slits 41 extending in the tubular direction, and both fastenings provided at both ends of the slits 41 of the tubular cover 4a so as to face each other. It is composed of a piece 4b and a reinforcing angle 4c attached to each of the fastening pieces 4b. Reference numeral 5 denotes a bolt and nut for tightening and mounting the protective cover 4, which is inserted into both holes 42 of both tightening pieces 4b and the reinforcing angle 4c. In the figure, 6 is a washer and 7 is a cover contact plate.
【０００３】 このように鋼管杭の防食テープ被覆工法は防食テープ３と保護カバー４との組 合せにより鋼管杭の防食を行うものであり、特に桟橋，橋脚などの港湾構造物と して使用される鋼管杭の防食方法として開発されたものである。従って、鋼管杭 １の外表にある保護カバー４には、絶えず波浪による外力や流木等の海上浮遊物 の衝突による衝撃が掛ることになる。As described above, the method of coating the steel pipe pile with the anticorrosion tape protects the steel pipe pile by combining the anticorrosion tape 3 and the protective cover 4, and is particularly used as a harbor structure such as a pier or a pier. It was developed as a corrosion protection method for steel pipe piles. Therefore, the protective cover 4 on the outer surface of the steel pipe pile 1 is constantly subjected to an external force due to waves and an impact due to the collision of floating floating materials such as driftwood.
【０００４】[0004]
しかしながら、従来の保護カバー４は図４，図５に示すようにボルトの頭やナ ットが外部に突出するボルトナット５により鋼管杭１に取付けられていたので、 このボルトナット５に波浪による外力や流木等の衝撃が直に掛り、ボルトナット ５が緩み，またはボルトナット５が腐食されて保護カバー４の締付け力が低下し 、保護効果が低下する欠点があった。 However, as shown in FIGS. 4 and 5, the conventional protective cover 4 is attached to the steel pipe pile 1 by the bolt nuts 5 whose heads and nuts project to the outside. There is a drawback that the external force or the impact of driftwood is directly applied, the bolt nut 5 is loosened or the bolt nut 5 is corroded, the tightening force of the protective cover 4 is reduced, and the protective effect is reduced.
【０００５】 この考案は上記した従来の保護カバーの問題点を除くためになされたもので、 ボルトの頭あるいはナットを締付片の凹所内に詰物により埋設することによりボ ルトナットの緩みや腐食を防止し、長期にわたり強固に鋼管杭に取付けうる鋼管 杭の防食テープ被覆工法用保護カバーを提供するにある。This invention was made to eliminate the above-mentioned problems of the conventional protective cover. By embedding the bolt head or the nut in the recess of the tightening piece with a filling material, loosening and corrosion of the bolt nut can be prevented. The purpose of the present invention is to provide a protective cover for the steel pipe pile anti-corrosion tape coating method that can prevent and firmly attach to the steel pipe pile for a long period of time.
【０００６】[0006]
この考案に係る鋼管杭の防食テープ被覆工法用保護カバーは、筒方向に沿う割 目を有しかつこの割目を利用して鋼管杭の表面に被嵌せしめられる筒カバーと、 この筒カバーの前記割目の両端側に対向状に設けられる両折曲片と、この両折曲 片にそれぞれ装着された後ボルトナットにより結合されて前記筒カバーを前記鋼 管杭の表面に取付ける両締付片とからなり、 かつ前記締付片に、前記折曲片を挿入する溝と、前記ボルトの頭あるいはナッ トを収容する凹所と、この凹所に固着されて前記ボルトの頭あるいはナットを凹 所内に埋設せしめうる詰物とを備えたものである。 A protective cover for a steel pipe pile according to the present invention for use in an anticorrosion tape coating method has a slit along the tubular direction, and a tubular cover which is fitted to the surface of the steel pipe pile by utilizing the split, Both bent pieces that are provided opposite to each other on both ends of the split and the two tightening that attaches the tubular cover to the surface of the steel pipe pile by connecting the bent pieces with bolt nuts attached to the bent pieces. A groove for inserting the bent piece, a recess for accommodating the head or nut of the bolt, and a head fixed to the recess for fixing the head or nut of the bolt. It is provided with a padding that can be embedded in the recess.
【０００７】[0007]
この考案においては、ボルトの頭あるいはナットを締付片の凹所内に詰物によ り埋設できるのでボルトナットの緩みや腐食を防止できると共に、溝を利用して 締付片を筒カバーの折曲片に挿入して装着できるので締付片の筒カバーへの脱着 が容易になる。 In this invention, since the head of the bolt or the nut can be embedded in the recess of the fastening piece by the filling, the bolt nut can be prevented from loosening or corrosion, and the groove can be used to bend the fastening piece of the cylinder cover. Since it can be inserted and installed in one piece, the fastening piece can be easily attached to and detached from the cylinder cover.
【０００８】[0008]
この考案の一実施例を図１〜図３について説明する。図１は結合部分を示す断 面図、図２は図１の締付片を示す斜視図、図３は図２の線 III−III の断面図で あり、前記従来のものと同一または相当部分には同一符号を付して説明を省略す る。 An embodiment of this invention will be described with reference to FIGS. 1 is a cross-sectional view showing the connecting portion, FIG. 2 is a perspective view showing the fastening piece of FIG. 1, and FIG. 3 is a sectional view taken along the line III-III of FIG. Are denoted by the same reference numerals and description thereof will be omitted.
【０００９】 図において、８は従来の保護カバー４と同様の働きをする保護カバーで、筒方 向に沿う割目８１を有する筒カバー８Ａと、この筒カバー８Ａの割目８１の両端 側に対向状に設けられる両折曲片８Ｂと、この両折曲片８Ｂにそれぞれ装着され た後ボルトナット５により結合されて筒カバー８Ａを鋼管杭１の表面に取付ける 両締付片８Ｃとで構成されている。締付片８Ｃは、折曲片８Ｂを挿入する溝８ａ と、ボルトの頭あるいはナット５を収容する凹所８ｂと、この凹所８ｂに固着さ れてボルトの頭あるいはナット５を凹所８ｂ内に埋設せしめうる水中硬化型エポ キシ樹脂などからなる詰物８ｃとを有していると共に、さらに結合面側にボルト 通し孔８ｄと背面側に締付け用開口部８ｅとを有している。In the figure, reference numeral 8 denotes a protective cover that functions in the same manner as the conventional protective cover 4, and has a tubular cover 8A having a split 81 along the tubular direction and both ends of the split 81 of the tubular cover 8A. Comprised of both bent pieces 8B provided opposite to each other, and both tightening pieces 8C attached to the both bent pieces 8B and coupled by rear bolt nuts 5 to attach the tube cover 8A to the surface of the steel pipe pile 1 Has been done. The tightening piece 8C includes a groove 8a into which the bent piece 8B is inserted, a recess 8b for accommodating the bolt head or the nut 5, and a recess 8b fixed to the recess 8b to secure the bolt head or the nut 5 in the recess 8b. It has a padding 8c made of a water-curable epoxy resin or the like that can be embedded inside, and further has a bolt through hole 8d on the coupling surface side and a tightening opening 8e on the back surface side.
【００１０】 このようにボルトの頭あるいはナット５が締付片８Ｃの凹所８ｂ内に詰物８ｃ により埋設されるので、ボルトナット５の緩みや腐食が防止され、従って保護カ バー８の締付け力が低下して保護効果が低下するということがなく保護カバー８ を長期にわたり強固に鋼管杭１に取付けることができる。Since the bolt head or the nut 5 is thus embedded in the recess 8b of the tightening piece 8C by the filling 8c, the bolt nut 5 is prevented from being loosened or corroded, so that the tightening force of the protective cover 8 is prevented. The protective cover 8 can be firmly attached to the steel pipe pile 1 for a long period of time without lowering the protective effect.
【００１１】 また、保護カバー８の締付片８Ｃの部分にボルトの頭やナット５が突出しない ので、波浪による外力の逃げがスムーズに行われると共に流木等の海上浮遊物の 引っ掛りが少なくなって保護カバーの受ける衝撃が緩和される。Further, since the head of the bolt and the nut 5 do not project to the tightening piece 8C of the protective cover 8, the external force can be smoothly escaped by the waves and the floating floating matter such as driftwood is less likely to be caught. Impact on the protective cover is reduced.
【００１２】 さらに、筒カバー８Ａの割目８１側に折曲片８Ｂを形成するだけでよいので、 筒カバー８Ａの加工がし易く、コストダウンが図れる。また、この折曲片８Ｂに 締付片８Ｃを溝８ａにより挿入するだけで装着できるので、締付片８Ｃを施工現 場などあらゆる場所で容易に装着できる。Furthermore, since it is only necessary to form the bent piece 8B on the split 81 side of the tubular cover 8A, the tubular cover 8A can be easily processed and the cost can be reduced. Further, since the fastening piece 8C can be attached to the bent piece 8B simply by inserting the fastening piece 8C into the groove 8a, the fastening piece 8C can be easily attached at any place such as a construction site.
【００１３】 また、両締付片８Ｃは、図１に示す結合状態では断面形状が左右対称形になる ので、図２に示すものを上下逆さにして使用でき、一種類のもので共用できる。 また、この締付片８Ｃは半硬質プラスチック樹脂，軟質プラスチック樹脂で押出 し成形できる。従って、折曲片８Ｂとの密着性がよく両者の離脱が無くなる。 なお、締付片８Ｃと筒カバー８Ａとは金属でも良い。Further, since both fastening pieces 8C have a bilaterally symmetrical sectional shape in the coupled state shown in FIG. 1, the one shown in FIG. 2 can be used upside down, and one type can be used in common. The fastening piece 8C can be extruded from a semi-hard plastic resin or a soft plastic resin. Therefore, the adhesiveness with the bent piece 8B is good and the separation of the both is eliminated. The fastening piece 8C and the tube cover 8A may be made of metal.
【００１４】[0014]
【考案の効果】 以上のように、この考案によればボルトの頭あるいはナットが締付片の凹所内 に詰物により埋設されるので、ボルトナットの緩みや腐食が防止され、従って保 護カバーの締付け力が低下して保護効果が低下するということがなく保護カバー を長期にわたり強固に鋼管杭に取付けうるという効果が得られる。As described above, according to the present invention, since the head of the bolt or the nut is buried in the recess of the tightening piece by the filler, loosening and corrosion of the bolt and nut are prevented, and therefore the protection cover is protected. The effect that the protective cover can be firmly attached to the steel pipe pile for a long period without the tightening force decreasing and the protective effect decreasing is obtained.
【００１５】 また、この考案によれば締付片の部分にボルトの頭やナットが突出しないので 、波浪による外力の逃げがスムーズに行われると共に流木等の海上浮遊物の引っ 掛りが少なくなって保護カバーの受ける衝撃が緩和されるという効果も得られる 。Further, according to this invention, since the head of the bolt and the nut do not project to the fastening piece portion, the external force can be smoothly escaped by the wave and the floating floating matter such as driftwood is less caught. It also has the effect of reducing the impact on the protective cover.
【００１６】 さらに、この考案によれば筒カバーの割目側に折曲片を形成するだけでよいの で筒カバーの加工がし易く、コストダウンが図れるし、またこの折曲片に締付片 を溝により挿入するだけで装着できるので締付片を施工現場などあらゆる場所で 容易に装着できるという効果も得られる。Further, according to this invention, since it is only necessary to form the bent piece on the split side of the tube cover, the tube cover can be easily processed, the cost can be reduced, and the bent piece can be tightened. Since it can be attached simply by inserting the piece in the groove, the effect that the tightening piece can be easily attached at any place such as the construction site is obtained.
