近些年来,随着科学生产技术的不断发展,各种高强度钢材不断的受到人们的关注与应用。就目前的房屋建筑施工而言,也逐步实现了由传统的低强度钢材想高强度钢材和预应力混凝土方向发展。预应力混凝土作为目前建筑工程项目中人们关注的重点结构,成为工程施工的核心重点,也是目前社会发展的核心内容。在现代化建筑工程项目中,各种大跨度和超高层建筑结构的出现为预应力混凝土的施工提出了新的施工要求和技术模式。本文以实际工程为例,阐述了高大跨预应力混凝土的施工技术和要点。
In recent years, with the continuous development of science and technology, a variety of high-strength steel constantly by the people’s attention and application. For the current construction of housing, it is also gradually realized by the traditional low-strength steel to high-strength steel and prestressed concrete direction. As the key structure of people’s attention in the current construction projects, the prestressed concrete has become the core emphases of construction and also the core content of the current social development. In the modern construction project, the emergence of various long-span and super-tall buildings brings forward new construction requirements and technical models for the construction of prestressed concrete. In this paper, the actual engineering as an example, elaborated the construction technology and key points of high-span prestressed concrete.
