Square multi-cavity steel plate-concrete composite floor

Abstract

The invention discloses a square multi-cavity steel plate-concrete composite floor, and belongs to the field of constructional engineering. The square multi-cavity steel plate-concrete composite floorcomprises a multi-cavity space steel floor and concrete; the concrete is poured into the square multi-cavity steel floor to form a combined integral component; the square multi-cavity steel floor iscomposed 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 the square multi-cavity steel floor; and the concrete is poured into the steel floor to form the square multi-cavity steel plate-concrete composite floor. The square multi-cavity steel plate-concrete composite floor has the beneficial effect 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 floor after molding has better overall performance, the steel plate shell replaces steel bars and structural steels in a traditional floor slab to play the role of the framework, the constructionoperation of traditional form erecting and form stripping is avoided, the square multi-cavity steel plate-concrete composite floor can replace a traditional framework 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 square multi-cavity steel plate-concrete composite floor. Background technique [0002] At present, large supermarkets and shopping plazas, industrial and civil buildings, etc. are mainly cast-in-place concrete structures. This construction method has a long construction period and greatly affects the progress of the project. Construction noise and construction waste generated by construction will affect the daily life of surrounding people. It brings inconvenience, causes environmental pollution, and increases social cost. Moreover, the traditional concrete components commonly used in buildings are heavy, which leads to excessive deflection of the floors of large supermarkets and shopping plazas.

Problems solved by technology

[0002] At present, large supermarkets and shopping plazas, industrial and civil buildings, etc. are mainly cast-in-place concrete structures. This construction method has a long construction period and greatly affects the progress of the project. Construction noise and construction waste generated by construction will affect the daily life of surrounding people. Bring inconvenience, cause environmental pollution, increase social cost

Moreover, the traditional concrete components commonly used in buildings are heavy, which leads to excessive deflection of the floors of large supermarkets and shopping plazas. In order to reduce this situation, more steel bars must be arranged; at the same time, the traditional floor slabs have poor crack resistance and cracks are exposed, which reduces the use of components. years, on-site pouring has many construction procedures, requires maintenance, and has a long construction period, and is limited by the construction environment and climatic conditions; traditional concrete components cannot well restrain the lateral sliding of concrete when it is under force, so that it cannot give full play to the compressive strength of concrete strength; in addition, traditional concrete components need formwork support when pouring, and the formed concrete components themselves lack integrity, and the quality is not easy to control
