Rhombus multi-cavity steel plate-concrete composite beam

Abstract

The invention discloses a rhombus multi-cavity steel plate-concrete composite beam, and belongs to the field of constructional engineering. The rhombus multi-cavity steel plate-concrete composite beamcomprises a multi-cavity space steel beam and concrete; the concrete is poured into the rhombus multi-cavity steel beam to form a combined integral component; the rhombus multi-cavity steel beam is composed of a steel plate shell and steel plate cavities with notches; the steel plate is composed of five steel plates in a welding mode; the steel plate cavities with the notches are connected in aninserted mode up and down and welded in the steel plate shell to form a rhombus multi-cavity steel beam; and the concrete is poured into the steel beam to form the rhombus multi-cavity steel plate-concrete composite beam. The rhombus multi-cavity steel plate-concrete composite beam has the beneficial effects that the problems of liable cracking and exposure cracking of traditional concrete components can be solved, the steel plate cavities have a high lateral restraining effect on the concrete, the compressive property of the concrete can be fully played, the self weight is light, the composite beam after molding has better overall performance, the steel plate shell replaces steel bars and structural steels in the traditional floor slab to play the role of the template, the construction operation of traditional form erecting and form stripping is avoided, the rhombus multi-cavity steel plate-concrete composite beam can replace a traditional template in the construction site, the construction progress is increased, and the economic benefit is improved.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to the field of a diamond-shaped multi-cavity steel plate-concrete composite beam. Background technique [0002] At present, urban viaducts, long-span bridges, industrial and civil buildings, etc. are mainly cast-in-place concrete structures. This construction method has a long construction period, which greatly affects the progress of the project. It brings inconvenience to life, causes environmental pollution, and increases social costs. Moreover, the traditional concrete components commonly used in buildings are heavy and unsuitable for long-span structures; at the same time, the crack resistance is poor, and the cracks are exposed, which reduces the service life of the components. On-site pouring has many construction procedures, requires maintenance, and the construction period is long, and is affected by the construction environment. and climate conditions;...

[0002] At present, urban viaducts, long-span bridges, industrial and civil buildings, etc. are mainly cast-in-place concrete structures. This construction method has a long construction period, which greatly affects the progress of the project. It brings inconvenience to life, causes environmental pollution, and increases social costs

Moreover, the traditional concrete components commonly used in buildings are heavy and unsuitable for long-span structures; at the same time, the crack resistance is poor, and cracks are exposed, which reduces the service life of the components. On-site pouring has many construction procedures, requires maintenance, and the construction period is long and affected by the construction environment. and climatic conditions; traditional concrete components cannot well restrain the lateral sliding of concrete under stress, so that the compressive strength of concrete cannot be fully exerted; in addition, traditional concrete components need formwork support when pouring, and the formed concrete The integrity of the component itself is relatively lacking, and the quality is not easy to control
