Energy saving ribbed cavity floor slab

Abstract

An energy saving ribbed cavity floor slab comprises frame beams, ribbed beams and an energy-saving cavity components arranged between each frame beam and each ribbed beam or every two ribbed beams, and is characterized in that each energy-saving cavity component is a cavity body, which is formed by an upper board, a lower board and periphery wall boards; and at least one surface of the cavity body is provided with an insulation layer or / and a heat insulation layer. According to the invention, the mechanics performance of the cavity floor slab is not changed; the cavity floor slab has an own heat insulation processing function, so as to greatly improve the heat insulation and sound insulation performance. The heat insulation layer is embedded in the closed cavity, therefore the weatherability of the cavity is good, and besides, the heat insulation layer is flexibly arranged, cavity floor slabs with different heat insulation coefficients can be designed; each cavity component is specially arranged on a warping edge provided with the heat insulation layer, and the whole floor slab has a broken bridge type heat insulation effect via carrying out heat insulation process of the ribbed beams or the frame beams. The comprehensive performance of the cavity floor slab is improved, and the effect on energy conservation of buildings is qualitatively improved.

Description

technical field [0001] The invention relates to the energy-saving field of building technology, in particular to an energy-saving dense-ribbed cavity floor slab. Background technique [0002] With the rapid development of the economy, the urbanization process is accelerating, and the population is rapidly gathering in the city. Urban buildings are increasingly unable to meet people's needs for space, and urban buildings are striving to expand towards multiple and high-rise buildings. The acceleration of urban construction has also led to many revolutionary breakthroughs in construction technology, and one of them, the hollow floor technology, is eye-catching for its unique advantages. [0003] Hollow floor technology originated from prestressed hollow concrete prefabricated slabs in the 1960s and 1970s. Later, the method of embedding hollow circular tube mandrels and then pouring concrete became the second generation product of hollow floors, and finally developed to the cur...

Problems solved by technology

Although ordinary hollow-core floor technology has advanced to a higher level than traditional technologies in terms of thermal insulation and sound insulation, breakthrough products are still rare, especially for products with built-in thermal insulation treatment.
