Oblique crossing inclined grid steel-concrete hollow sandwich mesh-like wagon shell and arched roof structure

Abstract

The present invention discloses a kind of obliquely-crossed obliquely-placed grid reinforcement-concrete open-web sandwich reticulated barrel shell and barrel vault roof structure. It is made up by utilizing reinforcement-concrete crossed, obliquely-placed and combined open-web sandwich plate and bending it along span direction according to the curved or parabolic form. As compared with existent technique the invented concrete reduced thickness can be reduced by 30%-50%, its structure self weight can be reduced by 30%-50% and its reinforcement consumption can be reduced by 25%-30%, so that its construction cost also is reduced.

Description

Technical field: [0001] The invention relates to a building roof structure, which is a zero-Gauss curvature (K=0) oblique grid steel-concrete hollow interlayer reticulated cylindrical shell and cylindrical arch roof structure. Background technique: [0002] The reinforced concrete reticulated cylindrical shell and reticulated cylindrical arch roof structure is a space reticulated shell and reticulated arch structure with zero Gauss curvature that can cover a large span and has good mechanical performance. This structure has been successfully applied to large-span public and industrial buildings in the 1970s and 1980s, such as the roof of the "Student Canteen" (42m×60m) of Tongji University built in the early 1970s and the "Ocean Experimental Hall" in Hangzhou. The roof is a reticulated cylindrical shell or reticulated cylindrical arch structure composed of reinforced concrete solid cross-sections in three directions. This kind of roof using solid reinforced concrete has the...

AI Technical Summary

Problems solved by technology

This kind of roof using solid reinforced concrete has the disadvantage that the converted thickness of concrete is too large, so that the self-weight of the entire roof is too large, and the amount of concrete is large. Due to the heavy self-weight, it is difficult to apply to the roof with a large span. , and during construction, since all components need to be cast on site, the construction process is complicated and the construction progress is slow

At the beginning of the 21st century, steel reticulated shells and reticulated steel cylinder arch structures with zero Gauss curvature of steel structures are sometimes used in public and industrial buildings, but steel reticulated shells and reticulated steel cylinder arch structures consume a large amount of steel , the cost is high, and the durability, anti-rust and fire performance are poor, and the maintenance cost is high
