本考案は鋼矢板セル本体とセルアーク部とからなる鋼矢板セル構造物の継手部 材に関するものである。 The present invention relates to a joint material for a steel sheet pile cell structure including a steel sheet pile cell body and a cell arc portion.
【０００２】[0002]
従来の継手部材は図２に示すように鋼矢板セル本体Ａとアーク部Ｂとの継手部 Ｃに、図３および図４に示すようなＴ形継手（セルの形状によってはＹ形継手を 使用することもある）を使用して連結している。これらの継手部材はリベットま たは溶接で組立られているが、リベット組立はコストが高いことに加えてリベッ ト工不足および騒音公害などの難点があり、溶接組立の場合にはコストは安いが 、鋼矢板は炭素または燐の含有量が高いことから溶接部の材質劣化を生じやすく 、Ｔ形引張りにおいて図５に示すように直線形鋼矢板３と添接アングル５とを隅 肉溶接で結合した７，７′の溶接部Ｄに溶接部Ｄの拡大図で示すようにルート割 れ１０，１０′を生じて、低い荷重でこの個所から破壊する。 As shown in FIG. 2, a conventional joint member has a T-shaped joint as shown in FIGS. 3 and 4 at a joint portion C between a steel sheet pile cell body A and an arc portion B (a Y-shaped joint may be used depending on the shape of the cell. Sometimes it is used) to connect. Although these joint members are assembled by rivets or welding, the cost of rivet assembly is high, and there are drawbacks such as shortage of rivet work and noise pollution. Since steel sheet piles have a high carbon or phosphorus content, deterioration of the welded material is likely to occur, and in T-shaped tension, the straight steel sheet piles 3 and splice angles 5 are joined by fillet welding as shown in FIG. As shown in the enlarged view of the welded portion D, root splits 10 and 10 'are formed in the welded portion D of 7,7', which is broken at a low load.

本考案は鋼矢板の材質をかえることなく溶接による材質劣化を生じない強度の 強い低コストの溶接組立の継手部材を提供することを目的とするものである。 An object of the present invention is to provide a joint member for welding and assembling, which has a high strength and does not cause material deterioration due to welding without changing the material of the steel sheet pile.
【０００４】[0004]
本考案は上記目的を達成するためになされたものである。すなわち両側端縁に 係合爪を有する直線形鋼矢板の表面に、片側端縁にのみ係合爪を有する直線形鋼 矢板を当接し、さらに添接アングルで補強してＴ形あるいはＹ形などを構成した 異形鋼矢板を製作するとき、それぞれの結合部を二層以上の多層隅肉溶接で溶接 結合した鋼矢板セル構造物の継手部材である。 The present invention has been made to achieve the above object. That is, a straight steel sheet pile having engaging claws on only one side edge is brought into contact with the surface of a straight steel sheet pile having engaging claws on both side edges, and is further reinforced by a splicing angle to form a T-shape or a Y-shape. This is a joint member of steel sheet pile cell structure in which each joint is welded and joined by multi-layer fillet welding of two or more layers when manufacturing a modified steel sheet pile.
【０００５】 本考案を図面とともに詳細に説明する。 図１は本考案の一例にかかる鋼矢板セル構造物の継手部材を示すものであって 、両側端縁に係合爪１を有する直線形鋼矢板２の表面に、片側端縁にのみ係合爪 を有する直線形鋼矢板３を当接し、さらに添接アングル５で補強してＴ形を構成 したのち溶接結合部７，７，′８，８′，９，９′，を二層以上の隅肉溶接で結 合することを特徴としている。The present invention will be described in detail with reference to the drawings. FIG. 1 shows a joint member of a steel sheet pile cell structure according to an example of the present invention, in which the surface of a linear steel sheet pile 2 having engaging claws 1 on both side edges is engaged with only one side edge. A straight steel sheet pile 3 having claws is abutted and further reinforced with a splice angle 5 to form a T-shape, and then welded joints 7, 7, '8, 8', 9, 9'are made up of two or more layers. It is characterized by joining by fillet welding.
【０００６】 すなわち従来の単層隅肉溶接結合部の溶接金属が粗大な柱状晶の凝固組織とな ることにより、炭素または燐の含有量が高いことの悪影響が助長されて著しく延 性が低下してルート割れが発生しやすくなるのに対して、本考案になる図１のＴ 形継手部材は初層隅肉溶接の上に二層以上の重ね溶接を施して、初層の柱状晶を 焼きならし再結晶組織とすることによって炭素や燐の害を押えて溶接金属の延性 を著しく高めているために低い荷重でのルート割れは生じない。That is, since the weld metal of the conventional single-layer fillet welded joint has a solidified structure of coarse columnar crystals, the adverse effect of a high carbon or phosphorus content is promoted and ductility is significantly reduced. While the root cracking is likely to occur, the T-shaped joint member of the present invention shown in FIG. 1 has two or more layers of lap welding on the fillet weld of the first layer to form columnar crystals of the first layer. Since the normalization recrystallized structure suppresses the damage of carbon and phosphorus and significantly increases the ductility of the weld metal, root cracking does not occur at low loads.
【０００７】[0007]
本考案になる二層隅肉溶接結合で作成したＴ形継手部材（直線形鋼矢板は燐の 高いマリナー鋼矢板）のＴ形引張り試験を行なった結果、ルート割れは荷重が３ １０tonf／mで生じ、破壊荷重は４３２．５tonf／mであった。一方、従来の単層 溶接結合で作成したＴ形継手部材（直線形鋼矢板は燐の高いマリナー鋼矢板）の ルート割れは１６０tonf／mという低い荷重で発生し、破壊も３０８tonf／mであ り、本考案のＴ形継手部材にくらべて劣っていた。 As a result of a T-type tensile test of a T-shaped joint member (a straight steel sheet pile is a Mariner steel sheet pile with a high phosphorus content) made by the two-layer fillet welded joint according to the present invention, the root crack was a load of 310 tonf / m. It occurred and the breaking load was 432.5 tonf / m. On the other hand, the root crack of the T-shaped joint member (straight steel sheet pile is Mariner steel sheet pile with high phosphorus) made by the conventional single layer welded joint occurs at a low load of 160 tonf / m, and the fracture is 308 tonf / m. , Inferior to the T-shaped joint member of the present invention.
【０００８】[0008]
本考案は上記した構成であるので、低い荷重でルート割れを生ぜず強度が強い 鋼矢板セル構造物の継手部材を低コストで得ることができる。 Since the present invention has the above-mentioned configuration, it is possible to obtain a joint member of a steel sheet pile cell structure that does not cause root cracking under a low load and has high strength at low cost.
