Manufacturing technology for energy-saving environmentally-friendly building with dome

Abstract

The invention discloses a manufacturing technology for an energy-saving environmentally-friendly building with a dome. The manufacturing technology includes the steps that after a PVC membrane material is tailored, a sphere is made through high-speed friction and attachment, and the lower end of the membrane material is wrapped by a pulling rope; 2, the spherical membrane material is fixed to an annular foundation of the building; 3, the membrane material is blown into a preset shape through an air blower, and after air pressure becomes constant, spraying is performed for a first layer of polyurethane; 4, steel bar labels are inserted into the first layer of polyurethane as a thermal-insulation layer; 5, spraying is performed for several layers of polyurethane to cover the steel bar labels, and the heads of the steel bar labels are exposed; 6, according to the steel bar labels, steel bars are bound; 7, concrete is sprayed. The manufacturing technology used for the energy-saving environmentally-friendly building with the dome is suitable for civil buildings, warehouse buildings, large gymnasiums and others.

Description

technical field [0001] The invention relates to a spherical building structure and its manufacturing process, in particular to a manufacturing process of a domed energy-saving and environment-friendly building, which is a green energy-saving and environment-friendly building and its manufacturing process, and is suitable for civil buildings, storage buildings, large stadiums, etc. . Background technique [0002] Most of the concrete structures in China at this stage are regular shapes such as rectangles, and the concrete construction formwork is mainly wooden or steel formwork. For complex curved buildings, the structural design and actual construction are more difficult. PVC membrane is mainly used in tensile membrane structure, the surface stress can reach more than 3.03kN / m, and it has certain fireproof and thermal insulation properties. Polyurethane insulation layer, as a medium-to-high-end energy-saving insulation material, is mainly used in the inner tank of water hea...

Problems solved by technology

Thin shell structures are also used in construction, but the design is difficult and the construction formwork is complicated. Well-known buildings include the Sydney Opera House and the National Center for the Performing Arts of China, etc.

The inflatable membrane structure (ETFE material) is currently also used in a small number of applications, the surface is soft and full, but the cost is high, such as: Water Cube Stadium, etc.
