Abstract

The invention provides a dome steel structure and a construction method. The dome steel structure comprises a bottom ring beam, a top circle beam and an annular support. The bottom ring beam is located at the bottom of the dome steel structure, is of a closed ring-shaped structure and is provided with N N-equal-division points. The top circle beam is located on the top of the dome steel structure,is of a closed ring-shaped structure parallel to the bottom ring beam and is provided with N N-equal-division points. The annular support is arranged between the bottom ring beam and the top circle beam and comprises a lower portion annular support and an upper portion annular support. The lower portion annular support is formed by alternately and fixedly connecting multiple lower portion installation blocks and multiple lower block embedded installation parts. The upper portion annular support is formed by alternately and fixedly connecting multiple upper portion installation blocks and multiple upper block embedded installation parts. The construction method includes the following steps that the dome steel structure is decomposed into multiple individual installation blocks, and the installation blocks are then assembled into hoisting blocks and finally fixed in sequence according to the installation sequence. The dome steel structure and the construction method have the beneficialeffects of being small in weight, low in economic cost and convenient to build.

Description

technical field [0001] The invention relates to a domed steel structure and a construction method, belonging to the technical field of steel structures. Background technique [0002] The characteristics of the dome structure are firstly manifested in its "practical" meaning. The design of the dome structure was originally built for basic living space. In addition to the basic practical significance, dome buildings are more symbolic of the sky, the sky, nobility and holiness in architectural culture, so they are mostly used in royal palaces, ancestral temples and other buildings. As a roof form of ancient Western architecture, the dome has gone through a development process from simple to complex, from single-layer to multi-layer, from simple to gorgeous, and from inside to inside and outside. The dome has experienced the historical development and evolution process from ancestral temples, sacrificial temples to human buildings. [0003] The dome steel structure has the ad...
