Cornice steel skeleton and bracket steel skeleton for large-span big roof of pseudo-classic architecture and construction method of cornice steel skeleton and bracket steel skeleton

Abstract

The invention discloses a cornice steel skeleton and a bracket steel skeleton for a large-span big roof of a pseudo-classic architecture and a construction method of the cornice steel skeleton and the bracket steel skeleton. The steel skeletons are slantingly mounted at a cornice part of a main structure, and comprise the cornice skeleton and the bracket skeleton, wherein the cornice skeleton is a pipe truss, and an inclined plane support roof is formed by a lower support steel column, a low support steel-pipe column and an upper support column, the rigid connection is formed between the pipe truss and the above three parts; and the bracket skeleton is composed of an inclined strut for the bracket, a horizontal beam for the bracket and a needle beam for the bracket, the inclined strut for the bracket and the horizontal beam for the bracket are vertical in space, and the needle beam for the bracket is horizontally arranged. During construction, the integral assembling on ground and the segmental hoisting are adopted, during the hoisting, a reversible chain is adopted for adjusting so that to ensure the construction precision, then the steel skeleton is hoisted to a preset position for butt assembly in the air. With the adoption of the steel skeletons provided by the invention, the architectural shape of the pseudo-classic large-span roof can be perfectly realized, the construction process is safe and reliable, and the steel skeletons are suitable for the structure and the construction of the large-span roof of the pseudo-classic architecture.

Description

technical field [0001] The invention relates to a cornice bucket arch steel skeleton and a construction method thereof, in particular to a cornice bucket arch steel skeleton of a large-span antique building and a construction method thereof. Background technique [0002] Chinese traditional ancient architecture has a pivotal position in the history of world architecture with its simple and solemn appearance and smooth and changeable curves. In the field of traditional ancient buildings in our country, most of them are wood structures, brick-wood structures or masonry structures. In the emerging field of antique architecture, due to the shortage of timber resources and the limitations of traditional craftsmanship, traditional ancient architectural structures can no longer meet the special requirements of large spans and large cantilevers in modern architecture. The introduction of steel structure systems in antique buildings has been favored by architects and structural eng...
