Energy-saving cavity component

Abstract

The invention discloses an energy-saving cavity component, comprising a sealed cavity body, wherein an upper plate, a lower plate, and side plates all around are surrounded to form the sealed cavity body. The energy-saving cavity component is characterized in that at least one surface inside the cavity body is provided with a temperature-keeping layer or / and a heat-insulation layer. Without changing the mechanical property of the cavity component, the temperature-keeping, the energy-saving cavity component greatly enhances the heat-insulation and the sound-insulation properties of the cavity component; a temperature-keeping heat-insulation material is arranged in the sealed cavity, the weather resistance is good, and the excellent temperature-keeping and heat-insulation properties can be maintained for a long time; the temperature-keeping / heat-insulation layer can be arranged flexibly, and cavity bodies with different temperature-keeping heat-insulation coefficients can be designed aiming at different requirements; a turned edge with a temperature-keeping heat-insulation layer is arranged outside the cavity component, so that a spacing body between components as well as a jointing body between one component and one building still maintains excellent temperature-keeping and heat-insulation properties, and the temperature-keeping and heat-insulation properties of the whole body of the building are enhanced; and the comprehensive property of the cavity component is advanced, and the energy saving of the building is improved.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to an energy-saving cavity component. 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 the prestressed hollow concrete prefabricated slabs in the 1960s and 1970s. Later, the method of laying hollow circular tubes and then pouring concrete became the second generation product of hollow floors, and finally developed to the current stage of embedding hollow boxe...

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.
