Closed-section profiled steel sheet-concrete combined floor and construction method thereof

Abstract

The invention relates to a closed-section profiled steel sheet-concrete combined floor and a construction method thereof. The combined floor comprises a closed-section profiled steel sheet and concrete cast on the closed-section profiled steel sheet which is laid on steel beams of a steel structure main body, the bottom of the closed-section profiled steel sheet is fixedly connected with the steel beams, a top support is erected under the closed-section profiled steel sheet between steel beams, a lower iron forced bar is arranged in each wave trough of the closed-section profiled steel sheet, and an upper iron forced bar is correspondingly arranged above each lower iron forced bar, connected with the lower iron forced bar by a tensile bar and erected on an upper iron distribution bar into a groined shape. In the invention, the closed-section profiled steel sheet is also utilized as a floor bottom die to save construction material. By using the construction method, the construction period can be shortened, the cost can be decreased, the structural bearing force requirement is met, and the construction quality is ensured so that the invention is particularly suitable for public construction structures with high fireproof requirement.

Description

technical field [0001] The invention relates to a building floor, in particular to a floor in a steel structure building and a construction method thereof. Background technique [0002] In the construction of construction projects, due to the different design of engineering structures, in addition to the commonly used concrete building structures, steel structures are used more and more, especially in the design of public buildings, steel structures have developed by leaps and bounds in my country in recent years . [0003] The traditional concrete structure floor has been difficult to meet the needs of modern building construction due to the large investment of turnover materials, large steel materials and complicated construction methods. At present, the profiled steel plate used in construction has the advantages of light unit weight, high strength, and fast construction, and is a good building material and component. The profiled steel plate can be combined with concret...
