    为解决建筑高耗能和高污染等问题,国家正在积极推动绿色、节能、环保墙体结构的发展。其中,格构式混凝土墙结构体系作为一种新型墙体结构,具备保温节能、隔声耐火、轻质承重、施工便捷和环保等多重功能,近年来成为应用和研究的热点。本文简要介绍了格构式混凝土墙体形式,归纳总结了格构式混凝土墙体的轴压、抗酸侵蚀、热工、隔声、耐候、抗震等性能,提出现阶段格构式混凝土墙体研究中的问题和不足。研究表明:格构式混凝土墙体结构发展,是建筑材料循环利用和建筑垃圾资源化的重大需求,可用于建筑结构抗震设计;未来可从新型材料、整体结构防火试验、复杂环境下冻融试验等方面提升其物理性能,以及结合减震技术开展可恢复功能性、高层应用方面的研究,进一步提高其抗震性能,为格构式混凝土墙体及其结构的广泛应用提供重要的科学依据和技术保障。

    Abstract:

    To solve the problems of high energy consumption and high pollution of buildings, China is actively promoting the development of green, energy-saving and environmentally friendly wall structures. Among them, the lattice concrete shear wall structure system, as a new type of wall structure, has multiple functions such as heat preservation and energy saving, sound insulation and fire resistance, light weight bearing, convenient construction and environmental protection, and has become a hot spot of application and research in recent years. This paper briefly introduces the form of lattice concrete wall, summarizes the axial compression, bending, acid corrosion resistance, thermal, sound insulation, weather resistance, seismic and other properties of lattice concrete wall, and puts forward the problems and deficiencies in the research of lattice concrete wall at the present stage. The research shows that the development of lattice concrete wall structure is a major demand for the recycling of building materials and the recycling of construction waste, which can be used for seismic design of building structures. In the future, its physical properties can be improved from the aspects of new materials, overall structural fire test, freeze-thaw test in complex environment, etc., and the research on recoverable functionality and high-rise application can be carried out in combination with shock absorption technology to further improve its seismic performance. It provides important scientific basis and technical support for the wide application of lattice concrete walls and their structures.
