の接続方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for connecting two honeycomb plates, in which each end of the two honeycomb plates is connected by a rigid joint method that maintains strength.

持する剛接合方式の接続方法として、第１図、第
２図、第３図及び第４図のごとき従来例が知られ
ている。 In recent years, honeycomb boards used for the floorboards of aircraft, the bottoms and side walls of hovercraft, etc. have a structure in which the top and bottom of a honeycomb core are covered with a surface board, respectively. Conventional rigid joint connection methods as shown in Figures 1, 2, 3, and 4 maintain the strength so that the bending moment can continue when connecting at each connection end. Examples are known.

これらの接合方法では、ハニカムコア１の上下
をそれぞれ表面板２Ａ，２Ｂでふさいだ２個のハ
ニカム板３の各接続端部を、一方の表面板２Ａ，
２Ｂから接続板４、そして他方の表面板２Ａ，２
Ｂのごとく負荷が流れる方式であるが、第１図の
場合は、表面板２Ａ，２Ｂがその端部で補強され
ておらず、その結果、重量軽減の目的で表面板２
Ａ，２Ｂを出来うる限り薄くしたとすると、打鋲
の場合、表面板２Ａ，２Ｂの面圧にて強度を伝え
なければならないので、打鋲の本数が増え、工数
が増し、また接続板４の面積を拡げなければなら
ないという欠点がある。 In these joining methods, each connecting end of two honeycomb plates 3 whose upper and lower sides of the honeycomb core 1 are respectively closed with face plates 2A and 2B is connected to one of the face plates 2A and 2B.
2B to the connecting plate 4, and the other surface plate 2A, 2
This is a method in which the load flows as shown in Fig. 1, but in the case of Fig. 1, the top plates 2A and 2B are not reinforced at their ends, and as a result, the top plates 2A and 2B are not reinforced at their ends for the purpose of reducing weight.
Assuming that A and 2B are made as thin as possible, when driving rivets, the strength must be transmitted through the surface pressure of the surface plates 2A and 2B, which increases the number of rivets that need to be driven and increases the number of man-hours. The disadvantage is that the area must be expanded.

また、各接続端部を接着する場合は、ハニカム
板２Ａ，２Ｂを先に接着製作した後に、接合部を
接着することになるので、ハニカム板３の端部を
熱しなければならないため、高温キユアが不可能
であり、信頼性に乏しくなり、それをカバーする
ため、各接合端部の接合部の面積を拡げなければ
ならないという欠点がある。 In addition, when bonding each connection end, the honeycomb plates 2A and 2B are bonded and manufactured first, and then the joints are bonded, so the ends of the honeycomb plate 3 must be heated, so high temperature curing is required. However, there is a disadvantage in that the area of the joint at each joint end must be increased to compensate for the poor reliability.

次に、第２図及び第３図では、２個のハニカム
板３の各接続端部の上下の表面板２Ａ，２Ｂ内

ハニカム縁材５の内部にはハニカムコア１、また

メン構造の如くなり、その結果、モーメントを受
けざるを得ないので、それらの部材の強度を上げ
なければならなくなり、それだけ重量が嵩むとい
う欠点がある。 Next, in FIGS. 2 and 3, U-shaped honeycomb edge members 5 are attached to the upper and lower surface plates 2A, 2B at the connecting ends of the two honeycomb plates 3 by adhesive or the like to strengthen them. Therefore, the drawbacks of the conventional example shown in FIG. Since the honeycomb edge material 5 and the connecting plate 4 disappear over a considerable length, the honeycomb edge material 5 and the connecting plate 4 become like a rigid frame structure, and as a result, they have to receive a moment, so it is necessary to increase the strength of these members. However, the disadvantage is that it is heavier.

また、コア１の高さを低く押えると２Ａ側に打
鋲しようとした場合リベツトの先端が２Ｂ側のハ
ニカム縁材に当たり、打鋲が不可能となる。 Furthermore, if the height of the core 1 is kept low, when trying to drive a rivet on the 2A side, the tip of the rivet will hit the honeycomb edge material on the 2B side, making it impossible to drive the rivet.

更に、第４図の他の従来例のごとく、ハニカム
板３の各接続端部の上下の表面板２Ａ，２Ｂ内に

１図、第２図及び第３図の従来例における欠点は
是正されるが、インサート材６に可成りの剛性を
要求されるため、インサート材６に軽量なものが
使えなくなる。 Furthermore, as in the other conventional example shown in FIG. 4, the upper and lower surface plates 2A, 2B of each connection end of the honeycomb board 3 are filled with insert materials 6 such as wood, and the upper and lower surface plates 2A, 2B are filled with the insert material 6 such as wood. Each outer side of the connection end of is covered with a connection plate 4 in a sandwich-like manner, and each connection end is further covered with a connection plate 4, a surface plate 2A, 2B,
A fastening member 7 such as a bolt passing through the insert material 6
There is also a method in which two honeycomb plates 3 are connected by attaching a Although the drawbacks of the conventional example shown in FIG. 3 are corrected, the insert material 6 is required to have considerable rigidity, so it is impossible to use a lightweight insert material 6.

そのため、第４図において、インサート材６を
重量を軽減する目的で軽量で剛性のないものと
し、表面板２Ａ，２Ｂを極力薄くしたとすると、
鋲の面圧はより剛性のある表面板にのみ負荷し、
インサート材には負荷しなくなり、結局第１図と
同じになるという問題がある。 Therefore, in FIG. 4, if the insert material 6 is made lightweight and non-rigid for the purpose of reducing weight, and the surface plates 2A and 2B are made as thin as possible,
The surface pressure of the studs is applied only to the more rigid surface plate,
There is a problem that no load is applied to the insert material, and the result is the same as that shown in FIG. 1.

そこで、本発明は前記従来の欠点及び問題点を
解消するためになされたものであり、ハニカム板

を提供することを目的としたものである。 Therefore, the present invention has been made to solve the above-mentioned conventional drawbacks and problems, and it is possible to maintain the strength of the connecting end of the honeycomb plates and to connect two honeycomb plates without increasing the weight. The purpose is to provide a connection method.
