It is a necessary and fundamental technique for realization of a semisubmersible type megafloat to connect as fast as possible two large scale units at construction site, which have been carried to the site by towing boats. In this paper, a new type of mechanical connector, which is based on an idea of three bodies problem, is proposed instead of welding. This mechanical connector may work well to connect two units at the site in spite of circumstances of some extent of relative motions between two units caused by waves. In the 2001 fiscal year, wave tank tests were carried out by using a semisubmersible type model with mechanica connectors in the deck girders. In the 2002 fiscal year, a relatively large deck girder model with a mechanical connector was tested in order to study more detailed behaviors corresponding to fundamental loads such as tension and compression, hogging and sugging bending, shearing force, torsional moment and iterative axial loads. It can be concluded from these test results that the proposed mechanical connector has a possibility of actual usefulness.

这是一种实现半材料类型的巨型型巨型型的必要和基本技术，可以尽快连接建筑工地的两个大型单元，这些单元已通过拖放船将其运送到该地点。在本文中，提出了一种基于三个身体问题的想法的新型机械连接器，而不是焊接。尽管波浪引起的两个单位之间的相对运动，但这种机械连接器可能会很好地连接位点上的两个单元。在2001财政年度，通过使用甲板梁中的Mechanica连接器的半简易类型模型进行了波罐测试。在2002财政年度，测试了具有机械连接器的相对较大的甲板梁模型，以研究对应于张力和压缩，弯曲和建议弯曲，剪切力，扭转力，扭转力矩和迭代轴向载荷等基本载荷的更详细的行为。从这些测试结果可以得出结论，提出的机械连接器具有实际实用性。
