Definitions

  • the present invention relates, in general, to a pipe rack that supports pipes for transporting a variety of raw materials such as chemicals, gases in the loading docks and plants, and more particularly, to a pipe rack constructed with precast concrete members, which sharply reduces construction expenses using inexpensive concrete structures, remarkably reduces a construction period using precast concrete construction, reduces weight of precast concrete members to facilitate transportation and installation by forming the precast concrete members in a hollow structure, and applies pre-tension and post-tension in order to reinforce strength, and ensures a long lifespan.
  • This pipe rack is conventionally installed in a steel frame construction using H sections.
  • This conventional pipe rack having the steel frame construction has a disadvantage in that the prices of raw materials and the costs of construction are expensive. Particularly, the prices of raw materials, for instance steel materials, have sharply risen of late. For example, in the case in which the steel frames of 700 tons per unit are required, the construction costs required for fabrication, transportation, installation, and fireproofing of the steel frames amount to about 3.5 million dollars, which correspond to 5,000 dollars per ton. This means a sharp increase in the construction costs as compared to the conventional construction costs. Furthermore, the prices or the demand and supply of the steel materials frames are expected to be unstable in the future.
  • the conventional pipe rack having the steel frame construction has a drawback in that a construction period is long.
  • the steel frame construction process by nature cannot perform fabrication and installation at the same time, so that it is difficult to reduce the construction period.
  • the construction period including purchase and fabrication of the steel frames requires a range from 4 months to 5 months in Korea.
  • the transportation period of 2 months and the installation period of 6 to 7 months are required.
  • the countries in the Middle East experience twice the impact of the overall construction delays that Korea does.
  • the raw materials lately run short, and thus delay of the purchase period acts as a factor that delays the construction period.
  • the conventional pipe rack having the steel frame construction causes problems with delay of piping work and storage of piping materials. Since the pipe rack is not installed at a proper time, the piping work is often delayed despite sufficient piping materials. Further, the steel frames for the pipe rack and the piping materials are frequently carried into a construction field at the same time. In this case, a space for storing the materials in the construction field runs short, and thus a working space runs short. This insufficient working space has an influence on other works.
  • the conventional pipe rack having the steel frame construction has a problem with quality and safety managements resulting from welding work. Since a main process for the installation is the welding work, it is difficult to check quality of each welded zone, and there are many fires and injuries during the welding work.
  • the pipe rack can be installed using ordinary reinforced concrete.
  • This method has an advantage in that the construction costs are low, but has disadvantages in that the construction period is long and that the construction is complicated, because all the processes proceed in the construction field. Disclosure of Invention
