  • a heat power plant often needs a dry coal shed with net span of more than 76 meters generally, and sometimes even more than 100 meters because of the usage of coal stoker.
  • the net height is above twenty-eight meters generally.
  • a scientific, economical and reasonable scheme for the large-span closed shed with a great height is a cylindrical reticulated shell, which has been validated through calculation of mathematical theory and mechanical theory.
  • the installation process is a changing and developing process. The expenses and construction periods vary with different installation processes, thus the effect is different.
  • Traditional construction processes include an overall scaffold construction method and a local scaffold construction method.
  • the scaffold In the overall scaffold construction method, the scaffold is required to be built in the coverage area of the entire cylindrical reticulated shell, thus the construction period is long, and the cost is high; in the local scaffold construction method, firstly, the scaffold is built for installing an anchor ring, and the anchor ring extends towards two sides by adopting a high-altitude overhanging construction method based on the anchor ring. Since only partial scaffolds are required to be built, the local scaffold construction method is favorable for reducing the construction period and the construction cost.
  • Chinese Patent Application No. 200810231497.2 entitled “A High-Altitude Overhanging Construction Method for a Cylindrical Shell Type Bolted Ball Joint Net Frame” discloses a local scaffold construction method.
  • a scaffold with a height equivalent to the highest position of the cylindrical reticulated shell has to be built even in the local scaffold construction method, and as to the extra-large and extra-high cylindrical reticulated shells, the construction cost and the construction difficulty are still relatively high.
  • the invention provides a method for installing a large-span cylindrical reticulated shell.
  • a scaffold is not required to be built, and a crane is used as an auxiliary tool, therefore the method is simple and practical and has high reliability, low cost and short construction period.
  • the method for installing a large-span cylindrical reticulated shell comprises the following steps:
  • each reticulated vault at least comprises four support bases ( 1 ) symmetrically arranged on both sides of the reticulated vault and ball joints and pull rods which are respectively installed on the four support bases ( 1 ) and mutually connected into a net frame shape; firstly, a reticulated vault is installed and called as a mother vault, a rotatable ball joint ( 2 ) is respectively installed on the support base ( 1 ) on any side of the mother vault, and then other ball joints and pull rods on the mother vault are respectively installed in sequence by taking the rotatable ball joint ( 2 ) as the starting point; the mother vault which should be installed in a vertical high-altitude extending manner is installed in a transverse extending manner during the installation of the ball joints and the pull rods, and a lifting device ( 3 ) is used for lifting the extension tail end of the mother vault during the transverse
  • the ball joint in the symmetrical position of the rotatable ball joint ( 2 ) is fixed on the support base in the corresponding position, i.e., the installation of the entire mother vault is completed; a high-altitude overhanging construction method is adopted after the completion of installation of the mother vault, and other reticulated vaults adjacent to the mother vault are respectively installed in sequence along the axial extending direction of the mother vault until the completion of installation of the entire large-span cylindrical reticulated shell.
  • the rotatable ball joint ( 2 ) is rotatably installed on the support base ( 1 ) during the installation of the mother vault; the rotatable ball joint ( 2 ) is fixed with the support base after the completion of installation of the reticulated vaults and before the completion of installation of the entire large-span cylindrical reticulated shell.
  • the scaffold is not required, and the crane and other lifting devices are used as auxiliary tools, therefore, the installation process is simple and practical and is highly reliable, with a low cost and a short construction period.
  • FIG. 1 is an elevational view of an embodiment of the large-span cylindrical reticulated shell ;
  • FIG. 2 is an elevational view of the mother vault when the mother vault is being installed
  • FIG. 3 is an elevational view of the mother vault at the last stage of the assembling process

  • FIG. 6 is a schematic view of a ball joint.
  • FIG. 7 is a schematic view showing a high altitude overhanging construction method.
  • FIG. 8 is a schematic view of a finished structure by a method of installing a large-span cylindrical reticulated shell.
  • the method for installing the large-span cylindrical reticulated shell comprises the following steps:
  • each reticulated vault at least comprises four support bases ( 1 ) symmetrically arranged on both sides of the reticulated vault and ball joints and pull rods which are respectively installed on the four support bases ( 1 ) and mutually connected into a net shape frame; firstly, a reticulated vault called a mother vault is installed, two support bases ( 1 ) are respectively arranged on both sides of the mother vault in the embodiment, and a rotatable ball joint ( 2 ) is respectively installed on the support base ( 1 ) on any side of the mother vault; the rotatable ball joint ( 2 ) is rotatably installed on the support base ( 1 ).
  • the rotatable ball joint ( 2 ) can be bound on the support base ( 1 ) through a chain or a steel wire rope. As shown in FIG. 5 , one end of the steel wire rope ( 7 ) is connected to the support base ( 1 ), and the other end movably holds the ball joint ( 2 ). Alternatively, a deeper ball socket is directly arranged at the top end of the support base ( 1 ), and the rotatable ball joint ( 2 ) is installed in the ball socket; the rotatable ball joint ( 2 ) can be installed at the top end of the support base ( 1 ) by adopting the two methods above, which can rotate, but cannot fall off from the support base ( 1 ).
  • a lifting device ( 3 ) is used for properly lifting the extension tail end of the mother vault at the moment, so that the height of the extension tail end always allows the installation construction to be performed on the ground level, and the rotatable ball joint ( 2 ) gradually rotates to the designed angle along the rise of the extension tail end.
  • the lifting device ( 3 ) can adopt various devices capable of raising the height such as cranes, hoists, hydraulic jacks, chain blocks and the like. The mother vault is hung in the position where the stress is most reasonable, and the deformation is smallest during the lifting process according to the force principle.
  • the ball joint in the symmetrical position of the rotatable ball joint ( 2 ) is fixed on the support base, i.e., the installation of the entire mother vault is completed; after the completion of installation of the mother vault, the rotatable ball joint ( 2 ) can be fixed with the support base ( 1 ), by a fastening method, e.g., a welding method.
  • the installed mother vault is the first vault. After the installation of the mother vault, a high-altitude overhanging construction method is adopted to install the other reticulated vaults one by one longitudinally.
  • each reticulated vault After the installation of a top ball joint 51 in a bottom circumferential vault line, the very adjacent bottom ball joint 52 in a top circumferential vault line will be installed. This step is repeated until the whole reticulated vault is finished.
  • the whole large-span cylindrical reticulated shell is longitudinally divided into several reticulated vaults.
  • the span of each reticulated vault is equal to the designed span of the reticulated shell.
  • every ball joint ( 5 ) is connected to one circumferential vertical chord rod, one circumferential chord rod, and two flank rod to form an installing unit containing one ball and four rods.
  • a crane is then used to lift a unit to the proper installation position in the air, then the unit is connected to other installed units.
  • other reticulated vaults adjacent to the mother vault are respectively installed in sequence in an axially extending direction of the mother vault until the completion of the installation of the entire large-span cylindrical reticulated shell.
