Cold-bending thin-walled steel lattice column composite wall with built-in straw grass brick

Abstract

The invention discloses a cold-bending thin-walled steel lattice column composite wall with a built-in straw grass brick. The wall comprises a composite wall skeleton formed by a cold-bending thin-walled steel lattice column and a top guide rail and a bottom guide rail, the composite wall skeleton is filled with the straw grass brick, and cover panels are fixed to both sides of the composite wallskeleton. The wall has high shear resistance and compression bearing capacity and large out-of-plane stiffness, provides convenience for the combination wall to absorb and dissipate seismic energy, has the advantages of green environmental protection, thermal insulation, sound insulation and noise reduction, and achieves structural heat insulation integration. In a low-rise and multi-story steel structure building, the strength, stiffnes and ability to absorb and dissipate the seismic energy of the structure can be significantly improved, it is convenient to manufacture and process, the wall can be prefabricated and produced in a plant, and on-site assembly and construction are achieved; waste is turned into a treasure, which can produce good social and economic benefits, help to protect the environment, promote the sustainable development of green buildings and has broad application prospects.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a composite wall with built-in straw grass bricks and cold-formed thin-walled steel lattice columns. Background technique [0002] Straw is a by-product of grain production, with huge reserves, shorter growth cycle than wood and bamboo, and sustainable development. Under the general trend of global energy conservation and environmental protection, applying straw to the construction field can not only turn waste into wealth and produce good social and economic benefits, but also help protect the environment and promote the sustainable development of green buildings. [0003] Cold-formed thin-walled steel has the advantages of light weight, good plasticity and toughness, and recyclability. The structural form of cold-formed thin-walled steel residences is derived from light wood-structured residences. The design style is flexible and can meet the architectural require...

AI Technical Summary

Problems solved by technology

The existing composite wall has low shear and compressive bearing capacity, low out-of-plane stiffness, and is deficient in thermal insulation, energy saving, sound insulation, and environmental protection.
