繊維強化プラスチックで所望する形状の構造物を作成する場合、例えば骨材と樹脂を混合したシート状のものを金型で圧縮成型するプレス法などが用いられる。しかし、船舶において用いられるマスト類は、その船舶用にオーダーメイドされることが多く、大量生産されるものではないから、プレス法では金型そのものの生産コストが過大となってしまう。   When a structure having a desired shape is made of fiber reinforced plastic, for example, a press method in which a sheet of a mixture of an aggregate and a resin is compression molded with a mold is used. However, since masts used in ships are often made to order for the ships and are not mass-produced, the production cost of the mold itself becomes excessive with the press method.

The mast 10 and the plurality of beam portions 21 to 24 are made of glass fiber reinforced plastic. The beam portions 21 to 24 are members cut out of a flat plate made of glass fiber reinforced plastic. The mast 10 is a member formed by winding a plurality of glass fiber reinforced plastic sheets. The glass fiber reinforced plastic is made of, for example, a polyester resin, a vinyl ester resin, an epoxy resin or a phenol resin (hereinafter simply referred to as "resin").

図２（Ａ）は、図１（Ａ）において視点ａから見たときの平面図であり、図２（Ｂ）は、図１（Ａ）において視点ｂから見たときの平面図である。図に示すように梁部２１と梁部２２はいずれもマスト１０から水平方向に張り出している。梁部２１と梁部２２は形状が異なるが、梁部２２〜２４はすべて同じ形状である。   FIG. 2 (A) is a plan view as viewed from the viewpoint a in FIG. 1 (A), and FIG. 2 (B) is a plan view as viewed from the viewpoint b in FIG. 1 (A). As shown in the drawing, both the beam portion 21 and the beam portion 22 project horizontally from the mast 10. Although the beam 21 and the beam 22 have different shapes, all the beams 22 to 24 have the same shape.

図３は梁部２１の拡大左側面図であり、図４は梁部２１の拡大平面図である。図５は梁部２１を構成する各部品を示す平面図又は側面図である。梁部２１を構成する各部品は、ガラス繊維強化シートが積層されて成る例えば厚さ１０ｃｍの繊維強化プラスチック製の平板から切削加工により切り出された部材である。梁部２１においては、フランジ２１１に対してウェブ２１３が略垂直となるように樹脂接合され、フランジ２１２に対してウェブ２１３が略垂直となるように樹脂接合されている。また、フランジ２１１に対してウェブ２１４が略垂直となるように樹脂接合され、フランジ２１２に対してウェブ２１４が略垂直となるように樹脂接合されている。また、フランジ２１１に対してウェブ２１６が略垂直となるように樹脂接合され、フランジ２１２に対してウェブ２１６が略垂直となるように樹脂接合されている。フランジ２１１，２１２はいずれも板状であり、その板面が略平行である。ウェブ２１３、２１４はマスト１０に樹脂接合されている。   FIG. 3 is an enlarged left side view of the beam 21, and FIG. 4 is an enlarged plan view of the beam 21. As shown in FIG. FIG. 5 is a plan view or a side view showing each component constituting the beam portion 21. As shown in FIG. Each component constituting the beam portion 21 is a member cut out of a flat plate made of fiber reinforced plastic, for example, having a thickness of 10 cm and made of laminated glass fiber reinforced sheets. In the beam portion 21, resin bonding is performed so that the web 213 is substantially perpendicular to the flange 211, and resin bonding is performed such that the web 213 is substantially perpendicular to the flange 212. Further, resin bonding is performed so that the web 214 is substantially perpendicular to the flange 211, and resin bonding is performed such that the web 214 is substantially perpendicular to the flange 212. Further, resin bonding is performed so that the web 216 is substantially perpendicular to the flange 211, and resin bonding is performed such that the web 216 is substantially perpendicular to the flange 212. The flanges 211 and 212 are both plate-shaped, and the plate surfaces are substantially parallel. The webs 213, 214 are resin-bonded to the mast 10.

ウェブ２１３、２１４，２１６はいずれも板状である。ウェブ２１３とウェブ２１４はその板面が略直交するように配置される。また、ウェブ２１４とウェブ２１６はその板面が略直交するように配置される。ウェブ２１３とウェブ２１６はその板面が略平行である。ウェブ２１３，２１４には、軽量化及び空気抵抗の軽減を目的として、それぞれ貫通孔２１３ａ，２１４ａが設けられている。   The webs 213, 214, 216 are all plate-shaped. The webs 213 and the webs 214 are arranged such that their plate surfaces are substantially orthogonal to each other. Also, the webs 214 and the webs 216 are arranged such that their plate surfaces are substantially orthogonal to each other. The webs 213 and 216 are substantially parallel to each other. The webs 213 and 214 are provided with through holes 213a and 214a, respectively, for the purpose of weight reduction and reduction of air resistance.

各フランジ２１１，２１２にはマスト１０が挿入される貫通孔２１１ａ、２１２ａが設けられており、この貫通孔２１１ａ，２１２ａに挿入されたマスト１０がフランジ２１１，２１２に樹脂接合されている。さらにフランジ２１１及びマスト１０は、それぞれに樹脂接合されたリブ２１５によって固定されている。   The flanges 211 and 212 are provided with through holes 211a and 212a into which the mast 10 is inserted. The masts 10 inserted into the through holes 211a and 212a are resin-bonded to the flanges 211 and 212, respectively. Further, the flange 211 and the mast 10 are fixed by ribs 215 resin-bonded to each other.

このように互いに樹脂接合されたフランジ２１１，２１２及びウェブ２１３，２１４，２１６により、梁部２１の断面形状はＨ型になっている。つまり、梁部２１の断面二次モーメントが大きくなり、曲げ剛性が高くなっている。これにより、梁部２１は、船舶における常設物としての使用に十分耐えられるようになっている。   The cross-sectional shape of the beam portion 21 is H-shaped by the flanges 211 and 212 and the webs 213, 214 and 216 resin-bonded to each other as described above. That is, the second moment of area of the beam portion 21 is increased, and the bending rigidity is increased. As a result, the beam portion 21 can sufficiently withstand use as a permanent construction on a ship.

図６（Ａ）は梁部２２の拡大平面図であり、図６（Ｂ）は梁部２２の拡大正面図である。梁部２２においては、フランジ２２１に対して２枚のウェブ２２３が略垂直となるように樹脂接合され、フランジ２２２に対して２枚のウェブ２２３が略垂直となるように樹脂接合されている。２枚のウェブ２２３はいずれもマスト１０に樹脂接合されている。各フランジ２２１，２２２にはマスト１０が挿入される貫通孔２２１ａ、２２２ａが設けられており、この貫通孔２２１ａ，２２２ａに挿入されたマスト１０がフランジ２２１，２２２に樹脂接合されている。各ウェブ２２３には、軽量化及び空気抵抗の軽減を目的として、貫通孔２２３ａが設けられている。このように互いに接合されたフランジ２２１，２２２及びウェブ２２３により、梁部２２の断面形状はＨ型となっている。つまり、梁部２２の断面二次モーメントが大きくなり、曲げ剛性が高くなっている。これにより、梁部２２は、船舶における常設物としての使用に十分耐えられるようになっている。梁部２３，２４の形状及び構造も梁部２２と同じであり、船舶における常設物としての使用に十分耐えられるようになっている。   6 (A) is an enlarged plan view of the beam portion 22, and FIG. 6 (B) is an enlarged front view of the beam portion 22. As shown in FIG. In the beam portion 22, resin bonding is performed so that the two webs 223 are substantially perpendicular to the flange 221, and resin bonding is performed so that the two webs 223 are substantially perpendicular to the flange 222. Both webs 223 are resin-bonded to the mast 10. The flanges 221 and 222 are provided with through holes 221a and 222a into which the mast 10 is inserted. The masts 10 inserted into the through holes 221a and 222a are resin-bonded to the flanges 221 and 222, respectively. Each web 223 is provided with a through hole 223a for the purpose of weight reduction and reduction of air resistance. The cross-sectional shape of the beam portion 22 is H-shaped by the flanges 221 and 222 and the web 223 joined to each other in this manner. That is, the second moment of area of the beam portion 22 is increased, and the bending rigidity is increased. As a result, the beam portion 22 can sufficiently withstand use as a permanent construction on a ship. The shape and structure of the beam portions 23 and 24 are also the same as the beam portion 22 so that they can be sufficiently used as permanent structures on a ship.

次に、上述したフランジ、ウェブ及びマストの樹脂接合の方法について、図７，８を参照して説明する。各ウェブの端部をフランジの板面に押し当てたとき、この押し当てられた箇所が樹脂接合される箇所となるが、その箇所には角部が形成される。本実施形態において、このように各ウェブの端部とフランジとの接合箇所に形成される角部については樹脂で埋めるようし、さらに、その樹脂を含む領域に対して複数のガラス強化繊維シートを重ねて樹脂で接合する。   Next, the method of resin bonding of the flange, the web, and the mast described above will be described with reference to FIGS. When the end portion of each web is pressed against the plate surface of the flange, the pressed portion becomes a portion to be resin-bonded, but a corner portion is formed in the portion. In this embodiment, the corner portions formed at the junctions between the end portions of the webs and the flanges are filled with the resin, and a plurality of glass reinforced fiber sheets are further added to the area including the resin. It piles up and joins with resin.

図７はウェブ２１３の下端部とフランジ２１２との接合箇所の断面図である。図に示すように、例えば梁部２１においては、ウェブ２１３の下端部とフランジ２１２の板面とによって両者の接合箇所には角部が形成される。この角部、及びウェブ２１３の下端部とフランジ２１２との間のスペースは樹脂３０１で埋められる。これにより、ウェブ２１３の下端部とフランジ２１２とが樹脂接合される。さらに、この角部を埋めた樹脂３０１を含む領域に対して、複数（ここでは２枚）のガラス強化繊維シート３０２ｂが重ねられて樹脂で接合される。これにより、ウェブ２１３とフランジ２１２との接合箇所の強靭化が図られている。ウェブ２１３の上端部とフランジ２１１との接合箇所についても上記と同様に、ウェブ２１３の上端部とフランジ２１１の板面とによって両者の接合箇所に形成される角部、及びウェブ２１３の上端部とフランジ２１２との間のスペースは樹脂３０１で埋められ、さらに、この角部を埋めた樹脂を含む領域に対して、複数のガラス強化繊維シートが重ねられて樹脂で接合される。   FIG. 7 is a cross-sectional view of the joint between the lower end of the web 213 and the flange 212. As shown in the figure, for example, in the beam portion 21, a corner portion is formed at the joint portion of the lower end portion of the web 213 and the plate surface of the flange 212. The corner and the space between the lower end of the web 213 and the flange 212 are filled with the resin 301. Thus, the lower end portion of the web 213 and the flange 212 are resin-bonded. Further, a plurality (two in this case) of glass reinforcing fiber sheets 302b are overlapped in a region including the resin 301 in which the corner portion is filled, and bonded by the resin. Thereby, the toughening of the junction between the web 213 and the flange 212 is achieved. In the same manner as described above, the joint between the upper end of the web 213 and the flange 211 is also formed at the corner formed at the joint between the upper end of the web 213 and the plate surface of the flange 211 and the upper end of the web 213 A space between it and the flange 212 is filled with a resin 301, and a plurality of glass reinforcing fiber sheets are overlapped and joined with a resin to a region containing the resin in which the corner is filled.

梁部２１〜２４においては、図７に示したような樹脂接合の方法により、ウェブとフランジが互いに樹脂接合される。また、各ウェブとマスト１０との接合箇所、及び、各フランジとマスト１０との接合箇所も、図７に示したような方法で樹脂接合される。これにより、各接合箇所の強靭化が図られている。   In the beam portions 21 to 24, the web and the flange are resin-bonded to each other by the method of resin bonding as shown in FIG. Further, the joint between each web and the mast 10, and the joint between each flange and the mast 10 are also resin-joined by the method as shown in FIG. Thereby, the toughening of each junction is achieved.

図８は、マスト１０の断面図であり、マスト１０の軸方向に垂直な断面構造を示している。マスト１０は、繊維の延伸方向が互いに異なる方向の複数（図８では３枚）のガラス強化繊維シート１０１ａ，１０１ｂ，１０１ｃが周方向に巻き回されて成る。ガラス強化繊維シートの繊維の延伸方向が互いに異なるとは、例えば、繊維の延伸方向がマスト１０の周方向に一致するように巻き回されたガラス強化繊維シートと、繊維の延伸方向がマスト１０の軸方向に一致するように巻き回されたガラス強化繊維シートとがあるということである。   FIG. 8 is a cross-sectional view of the mast 10 and shows a cross-sectional structure perpendicular to the axial direction of the mast 10. The mast 10 is formed by winding a plurality of (three in FIG. 8) glass reinforced fiber sheets 101a, 101b, and 101c in the circumferential direction in directions in which the stretching directions of the fibers are different from each other. That the fiber stretching directions of the glass reinforced fiber sheet are different from each other means, for example, a glass reinforced fiber sheet wound so that the fiber stretching direction matches the circumferential direction of the mast 10 and the fiber stretching direction of the mast 10 That is, there is a glass reinforcing fiber sheet wound to coincide with the axial direction.

マスト１０の軸方向から見た場合に、マスト１０を構成する各々のガラス強化繊維シート１０１ａ，１０１ｂ，１０１ｃがそれぞれ巻き回されて重なる部分１０２ａ，１０２ｂ，１０２ｃは、繊維シート１０１ａ，１０１ｂ，１０１ｃごとに異なる位置である。つまり、ガラス強化繊維シート１０１ａが巻き回されて重なる部分１０２ａと、ガラス強化繊維シート１０１ｂが巻き回されて重なる部分１０２ｂと、ガラス強化繊維シート１０１ｃが巻き回されて重なる部分１０２ｃとは、マスト１０の周方向における位置が一致していない。   When viewed from the axial direction of the mast 10, the portions 102a, 102b and 102c where the respective glass reinforced fiber sheets 101a, 101b and 101c constituting the mast 10 are respectively wound and overlapped are the fiber sheets 101a, 101b and 101c. Different positions. That is, the portion 102a in which the glass reinforced fiber sheet 101a is wound and overlapped, the portion 102b in which the glass reinforced fiber sheet 101b is wound and overlapped, and the portion 102c in which the glass reinforced fiber sheet 101c is wound and overlapped are the mast 10 Position in the circumferential direction does not match.

各々のガラス強化繊維シート１０１ａ，１０１ｂ，１０１ｃが巻き回されて重なる部分は、各ガラス強化繊維シートの切れ目に相当する部分であるから、そのような切れ目に相当しない部分に比べて、強度としては弱くなる。そこで、このような重なり部分の周方向における位置を各ガラス強化繊維シート１０１ａ，１０１ｂ，１０１ｃごとに異ならせることで、強度の弱い部分が１カ所に集中することを避けている。これにより、マスト１０の剛性の低下を抑制している。   The portions where the respective glass reinforcing fiber sheets 101a, 101b and 101c are wound and overlapped are portions corresponding to the cuts of the respective glass reinforcing fiber sheets, and therefore, in terms of strength as compared with portions not corresponding to such cuts. become weak. Therefore, by making the positions of such overlapping portions in the circumferential direction different for each of the glass reinforcing fiber sheets 101a, 101b, and 101c, it is avoided that the portions with weak strength are concentrated at one place. Thereby, the fall of the rigidity of mast 10 is controlled.

上記のような船舶用構造物を作成する手順は以下のとおりである。まず、第１工程において、ガラス強化繊維シートを積層した平板から、上下フランジ（第１平板部材、第３平板部材）及びウェブ（第３平板部材）を切削加工によって切り出す。第２工程において、一方のフランジ（第１平板部材）に対してウェブ（第２平板部材）が略垂直となるように樹脂接合し、他方のフランジ（第３平板部材）に対してウェブ（第２平板部材）が略垂直となるように樹脂接合して梁部２１〜２４を作成する。第３工程において、繊維の延伸方向が互いに異なる方向の複数のガラス強化繊維シートを巻き回してマスト１０を作成する。第４工程において、マスト１０に対して梁部２１〜２４を樹脂接合等で固定する。なお、第１工程及び第２工程と第３工程との順序は、入れ替えてもよいし、同時に行ってもよい。   The procedure for creating a ship structure as described above is as follows. First, in a first step, upper and lower flanges (first flat plate member, third flat plate member) and a web (third flat plate member) are cut out from a flat plate on which glass reinforced fiber sheets are laminated. In the second step, resin bonding is performed so that the web (second flat plate member) is substantially perpendicular to one flange (first flat plate member), and the web (third flat plate member) is joined to the other flange (third flat plate member) (2) The flat plate members are resin-bonded so as to be substantially vertical, and the beam portions 21 to 24 are formed. In the third step, a plurality of glass reinforcing fiber sheets having different fiber stretching directions are wound to form the mast 10. In the fourth step, the beam portions 21 to 24 are fixed to the mast 10 by resin bonding or the like. The order of the first and second steps and the third step may be interchanged or may be performed simultaneously.
