Compared with the product introduction and flat grid, shell of good mechanical performance, high stiffness, small weight, weight of steel, is a better structure suitable for large span roof construction. The disadvantage is the surface increases the roof surface area and building space, the structure treatment, support structure and construction are very complex. From the construction of Internet shell is divided into single and double two categories. Single layer lattice shell span of not more than 40 meters. Parameters of 1 cylindrical reticulated shell: shape reticulation structure cylindrical surface, both bar and shell structure of the stress characteristics of curvature, only in a single direction, often covered rectangular plane architecture. According to the arrangement of the single-layer reticulated shell is of four kinds: the unidirectional oblique rod orthogonal mesh, cross diagonal rods of orthogonal mesh, lamella, three dimensional grid. Grid layout modes of double-layer grid may refer to the grid structure with different. Shell height to wavelength ratio generally in 1/6 ~ 1/8. Double layer reticulated shell thickness should be 1/20 ~ 1/30 wavelength. 2 spherical reticulated shell: used for covering large span grid roof, common forms: ribbed, Wade ribbed, lamella, geodesic, three dimensional grid. By cutting on the shell surface, spherical reticulated shell can be used for polygon, rectangle and triangle flat roof of a building. The 3 hyperbolic paraboloid shell: fixed at both ends of a wire inclination of a line in space along the two (a line or curve) parallel moving and form. Single layer reticulated shell used straight beam bar, double layer reticulated shell adopts linear truss, two orthogonal and hyperbolic paraboloid shell. The shell is used mostly for asymmetric building plane, novel and lightweight construction. Functional use tank use, shell of good mechanical performance, high stiffness, small weight, weight of steel province other shows that Baoding era of Petrochemical Equipment Co. Ltd is a design and development, production and sales, business services, construction and installation in one of the Integrated Company. The company is Sinopec, China Petroleum Material and Equipment Corporation member units. The main products and business scope: storage tank and pipeline accessories series, aluminum (stainless steel) for inner floating roof, large storage tank roof, central drainage device, external floating roof tank one or two seal, floating oil absorbing device, insulation materials, anti-corrosion insulation engineering construction, underground pipeline detection.
