Reinforcement lightweight aggregate concrete flat beam structure

Abstract

The invention relates to a reinforcement lightweight aggregate concrete flat beam structure which comprises a column, a beam and a plate, wherein the beam is a flat beam made of a reinforcing steel bar and lightweight aggregate concrete, the width of the flat beam is more than or equal to the height; and the column is a reinforcement lightweight aggregate concrete column. The reinforcement lightweight aggregate concrete flat beam structure provided by the invention also has better properties of light weight, energy saving, environment friendliness, good durability and the like of the lightweight aggregate concrete under the condition of the advantages of reducing floor height, avoiding pipeline beam crossing and the like, greatly reduces self gravity of the whole building structure and improves earthquake resistant behaviour of the structure while ensuring bearing capacity, and has remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a building structure in the building field, in particular to a light-weight aggregate concrete flat beam structure with reinforcement. Background technique [0002] With the development of high-rise buildings in our country, more and more buildings are now restricted by the height limit of urban planning. The floor height is low and the column network is large. Appropriate stiffness and ductility. In this case, the conventional beam-slab structure can no longer meet the requirements, and the flat beam structure is one of the effective methods to solve such problems. [0003] Over the years, experts and scholars at home and abroad have conducted various studies on flat beam structural systems, such as the flexural and shear performance of flat beams under load, the beneficial effects of floors on beam-column joints, the internal and external cores of flat beam and column joints The mechanical mechanism of the area, as well as ...

Problems solved by technology

[0006] Among the current patents on lightweight aggregate concrete, CN 101078283A Li Guochang introduced a corrosion-resistant and fatigue-resistant lightweight aggregate concrete beam, which is composed of fiber-reinforced plastic bars, steel bars, and light aggregate wrapped by fiber-reinforced plastic bars The concrete layer is composed of lightweight aggregate concrete, but it is not a flat beam structure; CN 201050127Y Wang Guoliang and others proposed a composite floor slab of cast-in-place lightweight aggregate reinforced concrete, which includes a prefabricated formwork made of lightweight aggregate reinforced concrete The floor body is composed of shell members, steel wire mesh and cast-in-place lightweight aggregate concrete, but its beams are not flat beams; similar to the above two patents, the other patents using lightweight aggregate concrete floor slabs do not use flat beam structures
