Web plate perforated profile steel partially-wrapped recycled concrete beam and construction method thereof

Abstract

The invention is applicable to the technical field of structural engineering, and provides a web perforated profile steel partially-wrapped recycled concrete beam and a construction method thereof. The beam includes a profile steel, wherein a plurality of web plate openings are formed in a web plate of the profile steel in an array manner; and reinforcing assemblies which are arranged in the profile steel and are arranged on the two sides of the web plate. In addition, the profile steel is filled with recycled concrete. The beam has the advantages of being high in bearing capacity, good in anti-seismic property and capable of saving steel, and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a regenerative concrete beam partially wrapped with open-hole steel in the web and a construction method thereof. Background technique [0002] In daily life, ordinary reinforced concrete beams are commonly used, but with the rapid development of the national economy, buildings are gradually built in the direction of high-rise and long-span, while ordinary reinforced concrete beams have some shortcomings. Local instability is easy to affect the bearing capacity of the component. [0003] The consumption of steel is less, especially the emergence of some new tool-type formwork and construction machinery in recent years, so that the cast-in-place construction of concrete structure projects has developed rapidly. Designers have gradually brought concrete beams partially wrapped in steel into the building, but steel-concrete beams require a large number of formwork, a...

AI Technical Summary

Problems solved by technology

Designers have gradually brought concrete beams partially wrapped in steel into the building, but steel-concrete beams require a large number of formwork, and the concrete on both sides of the web is not well connected together, prone to local damage, which is not conducive to the overall performance of the component

[0004] The existing composite beams have many construction steps, and there may be disadvantages such as extended construction period that are not conducive to the application of composite structures. The industrialization and industrialization of construction projects have led to the production of prefabricated concrete structures. Although it brings fast construction and saves formwork, etc. Advantages, but may bring disadvantages such as poor overall performance of the structure

And at the same time of vigorous development, construction waste is also increasing day by day, which is not conducive to the development of the overall economy; therefore, a kind of web-opening steel part wrapping concrete beams is now provided to solve the above problems
