Steel-reinforced concrete base of large-span net rack roof and construction method of steel-reinforced concrete base

Abstract

The invention relates to a steel-reinforced concrete base of a large-span net rack roof and construction method of the steel-reinforced concrete base. The base comprises circular steel-reinforced concrete columns and rectangular steel-reinforced concrete beams, wherein the steel-reinforced concrete beams are supported against the steel-reinforced concrete columns, reinforcing steel bars are further assembled in the steel-reinforced concrete columns and the steel-reinforced concrete beams, each steel-reinforced concrete beam comprises supporting beams at the two ends and a cantilever beam, and the steel-reinforced concrete beams form a circular space or an elliptic space and used for supporting the net rack roof on the upper portion of a building. The characteristics of the two materials, namely, steel and concrete, can be given into full play through the base, the base has the advantages of being small in cross section size, high in rigidity, good in ductility and durability and capable of saving steel, the effective use space of the building is enlarged through the base, and the advantages that the net rack roof is high in rigidity and good in anti-seismic property can be given into full play.

Description

technical field [0001] The invention relates to the construction of large-span structural engineering in the civil engineering industry, in particular to a steel-reinforced concrete base for a large-span grid roof and a construction method thereof. Background technique [0002] With the development of science and technology and the progress of construction technology, long-span buildings have become one of the development directions of building structures. The grid structure is a new type of long-span space structure, which has the characteristics of large rigidity, small deformation, uniform stress distribution, and large energy efficiency. With the advantages of reducing the weight of the structure and saving materials, in recent years, grid roofs have been widely used in public buildings such as large shopping malls and stadiums. In the prior art, the supporting structure of the large-span grid roof, that is, the roof base is mostly a reinforced concrete structure or a st...

AI Technical Summary

Problems solved by technology

In the prior art, the supporting structure of the large-span grid roof, that is, the roof base is mostly a reinforced concrete structure or a steel structure. The concrete has high compressive strength, but its bending resistance is very weak. The cross-section of the reinforced concrete structure is generally large, which limits the construction The effective use of space, and steel, especially section steel, has strong bending resistance and good elastic-plastic properties, but it is easy to lose stability when it is under pressure, and it is easy to rust and not resistant to high temperature.

Utilizing reinforced concrete structure or steel structure as the foundation of the grid roof cannot give full play to the advantages of high rigidity and good seismic performance of the grid roof
