Abstract

The precast concrete structure is made up of precast concrete components that are connected in a reliable way and form a whole with on-site post-pouring concrete and cement-based grouting. It has a high degree of industrialization and standardization, and is also fast, efficient, energy saving and consumption reduction. Nowadays, it has become an important direction for the transformation and upgrading of construction industry in China. This study started from the form and classification of precast concrete structures. On the basis of design, production and installation, this study analyzed the points for attention in quality control of key links, such as component splitting and node connection design, detailed design of component production, quality inspection of component manufacturing process, component hoisting and temporary fixation. According to the specific problems in the construction of precast concrete structure, the corresponding entity quality supervision standard was formulated, which would be expected to improve the construction effect of precast concrete structure to a certain extent.
