Title:
LOWER HULL AND COLUMN COMBINING CONSTRUCTION IN TENSION RIG
Document Type and Number:
Japanese Patent JPS6130485
Kind Code:
A
Abstract:
PURPOSE:To simplify a joining operation by joining shelf board parts which have slightly larger circular parts than the outside diameter of a column and which have connecting parts in an integrated form, to be connected to the top and bottom surfaces of lower hulls, to said lower hulls, and forming a column part having the same diameter as the outside diameter of said column, between said upper and lower shelf board parts. CONSTITUTION:Shelf boards 11A, 11B which have circular parts slightly larger than the outside diameter of a column 4a, have connecting parts 12A, 12A', 12B, 12B' in an integrated form, to be connected to the top and bottom surfaces of lower hulls 3A, 3B respectively. Each of these shelf boards 11A, 11B is connected to the lower hulls 3A, 3B via the connecting parts 12A, 12A', 12B, 12B'. Connection is made not only to the top and bottom surfaces of the lower hulls but also to their side parts 13a, 13b. A column member with a diameter corresponding to the outside diameter of the column 4a is installed between the upper and lower shelf boards 11A, 11B, and a column 4a is joined to the top of a shelf board 10A. Thereby, a combining construction which facilitates a joining operation without need for carrying out a joining operation between complicated cubic curved surfaces, can be obtained.
