A Treatise On The Principles And Practice Of Dock Engineering

SHEDS AND WAREHOUSES AT BUENOS AYRES, ETC. 40I bays of 60 feet each, carried on cast-iron columns of H section, and are roofed with corrugated iron, and are enclosed by 15-inch brick walls built between the H columns, and fitted with sliding doors, one in each 15-foot bay. To avoid down pipes passing through the sheds to drainage channels under the floors, the centre gutters are made large enough to carry the rain- water to the ends of the buildings, the necessary fall being obtained by raising the bases of the middle columns. All the gutters are of |-inch galvanised steel plates. The floors are laid with a slope of 1 in 60, and, on the quay side, are raised 1 foot above the coping level. The height above ground level at the back of the shed is 3 feet 6 inches, and along this inner face a platform, 8 feet wide, has been constructed for the con- venience of the railway traffic. The total shed area provided is 432,000 square feet. The sheds are lighted by electricity. Each of the sheds has forty I6-candle-power incandescent lamps, hung from the tie-beams of the principals. In addition to these, and to arc lamps upon the quays, a terminal box is provided in each shed, to which a portable lamp may be connected, in case of more light being required in any part of the shed, or outside, when loading or unloading has to be carried on at night.” Sheds and Warehouses at Buenos Ayres.* The total capacity of the sheds and warehouses amounts to 687,378 cubic yards, and the total floor area to 230,595 square yards. The sheds are of iron, with corrugated iron roofs. They are mainiy built on piles in made ground. Each shed has a platform, 31 feet wide, on the dock side, covered by a verandah. Four of the thirteen warehouses have wooden roof-trusses, with tiles laid on planking. The remainder have iron roof-trusses, with a zinc covering, as weil as iron partition doors and iron window frames. These latter warehouses have an extra floor, making five in all, and have longi- tudinal platforms running the whole length of the front of the warehouses, so that goods can be deposited on any part of the platforms in order to be removed into the warehouses afterwards. The warehouses are built of rubble masonry up to the level of the quays, and from that level to the top, of brickwork. All the floors are of timber, with the exception of the ground floors over the bonds, which are of concrète in the proportion of 1 cement, 4 sand, and 6 stone, with a rendering of 1 inch of 1 cement and 1 sand. Figs. 389 to 391 illustrate the practice at this port. Various other instances of shed and warehouse construction, sufficiently intelligible without description, will be found in figs. 392, 393, and 394, which illustrate sheds at Zeebrugge and Emden, and a warehouse at Amsterdam. * Dobson on “Buenos Ayres Harbour Works,” Alin.
