Embodiment Construction

[0022] The patent of the present invention relates to the combination of autoclaved aerated concrete slab (ALC slab), bamboo and wood slab, and steel beam, so that the three can be more optimized for force transmission and give full play to the performance advantages of the material. Autoclaved aerated concrete slab (ALC slab) is a new type of floor slab made of cement, lime, sand or fly ash as the main raw materials. It has the advantages of light weight, environmental protection, good fire performance, good sound insulation effect and high degree of assembly. However, due to the introduction of a large number of pores, the strength of the concrete is low. The compressive strength of the cubic concrete is less than 5Mpa, and the tensile strength is about 1Mpa. When the stress is close to the failure load, the plastic deformation increases significantly, and surface cracks appear. Brittle failure. In order to make full use of the various excellent building thermal properties o...

Abstract

The invention provides a high-frequency welded thin-wall H-shaped steel beam-ALC-engineering bamboo-wood composite beam and a construction method thereof. The composite beam comprises engineering bamboo-wood plates, an autoclaved aerated concrete plate and a high-frequency welded thin-wall H-shaped steel beam, and two outer surfaces of the autoclaved aerated concrete plate are fixedly connected with the engineering bamboo-wood plates to form light composite floor slabs. The two light composite floor slabs are fixedly connected to the positions of two sides of a web of the thin-wall H-shaped steel beam to jointly form the assembled composite beam.

Description

technical field [0001] The technical field of building structure engineering, especially related to a kind of high-frequency welded thin-walled H-shaped steel beam-ALC-engineering bamboo-wood composite beam and its construction method Background technique [0002] The global warming caused by the development of industrialization has caused irreversible damage to the ecosystem and the earth's climate system. The construction industry has caused serious damage to the past environmental ecology. Therefore, low-carbon, green and ecological buildings have become the mainstream trend of construction development. Bamboo wood, as a natural and environmentally friendly material, is more suitable for use in green and livable houses. The pursuit of more portable and fast-assembling industrial construction is also an inevitable trend of future industrial development. [0003] There are relatively few studies on steel-bamboo-wood combined ALC slab composite beams at home and abroad, esp...
