Abstract:
A method of construction of an elevated annular platform, said platform having an inner and an outer edge and including a number of bail sections, the number being equal to the number of bails on the platform, and the dimensions of each bail section being determined from the width of the platform, the number of bails and the length of the center line; said method including the steps of:constructing an adequate foundation to take and support the weight of the platform and the dead and live loads to be applied thereon (when completed);erecting a curved, flanged metal support beam which is positioned along the center line of the intended position of the platform and elevated to the pre-determined height to ensure the required elevation of the platform, the top of said beam having an inward and an outward flange or flanged edge;preparing the bail sections, each bail section having an inner and an outer edge, and two radial sides, each bail section including:a side support means which is positioned along one radial side of the bail section and which is secured to the metal support beam; said means being positioned such that the side support means of one bail section is engageable with an immediately adjacent bail section;a panel of pre-cast material, which includes an inner edge of the same radius as that of the inner edge of the platform, an outer edge that is the same radius as the outer edge of the platform, and two straight sides that are the same length as the length of the side support means; the panel being positioned over the said support beam, and between the inner and outer edges of the platform and between the side support means of the bail section and the support means of the adjacent bail section;locating an upright edging around each of the inner and outer edges of said platform, and securing each said edging to the respective ends of the side support means, thereby providing a mould into which the material of the platform can be poured;positioning and securing within the mould the required reinforcing material;positioning and securing within the mould the required blanks, sleeves and packing for cut-outs and channels to be formed in the finished platform; andfilling the mould with filler material and allowing it to set and/or cure; wherein said filler material and said pre-cast material bond together to form a single structural layer.
