Not illustrated. 1919 edition. Excerpt: ...shell plating is called the deck stringer plate and is made especially heavy. It is connected by a heavy angle bar to the sheer strake of the shell plating and acts with it in furnishing upper flange strength to the ship as a girder. The deck stringer is fitted in every case whether the remainder of the deck is to be plated or merely planked. Its inner edge runs approximately parallel to its outer edge. The remainder of the deck plating is arranged in strakes parallel to the centre line of the ship. The seams are commonly joggled except in cases where the projecting laps would be objectionable, as for a deck to be covered with linoleum or protective deck plating, in which cases the deck plating is worked flush with butt and seam straps underneath. Fia. 54.--Connections at sides of watertight decks. The boundaries of the deck plating are connected to the intersecting coamings, shell plating or bulkheads by bounding or boundary bars or simple angles one flange of which is riveted to the deck plating and the other to the coaming, shell plating or bulkhead, as the case may be. Methods of connecting the deck plating of a water-tight deck to the shell plating are shown in the three upper sketches of Fig. 54. The stringer plate is notched out around each frame and forged angle staples are fitted between and around the frame bars. Typical constructions for angle, Z-bar and channel frames are shown, but numerous other arrangements are possible and will be found used to accomplish the same purpose--which is to furnish a means of making a completely water-tight connection of deck to shell. In the case of the highest deck of the hull such stapling is not necessary as the frames terminate below the deck. Here the stringer angle bar runs continuously...
