Square for measuring a diagonal length of ship structure

摘要

The present invention relates to a rectangular body for measuring the diagonal length of a ship structure, and its object is to check whether the blocks constituting the lower part of the ship structure are mounted at right angles to each other while being arranged adjacent to each other, A diagonal length of a space formed by a structure can be easily measured. The structure of the present invention includes a horizontal frame attached to an upper surface of a first block disposed at a lower portion of a ship; A vertical frame disposed on a sidewall of a second block disposed adjacent to the first block; An angular unit for measuring an angle between the horizontal frame and the vertical frame so that the upper surface of the first block and the side wall of the second block are vertically attached; A first tape sizing unit installed at an end area of the vertical frame; A second tape-sizing unit installed at an end area of the horizontal frame; And a tape measure for measuring a diagonal length of a cross section of a space formed by the first block and the second block, the one end being caught by the first tape measure hanger unit and the other end being caught by the second tape measure hanger unit It is a feature of the design to measure the diagonal length of a ship structure to be included.
