Development and analysis of prefabricated concrete buildings in Chengdu, China

Abstract

Prefabricated construction is an inevitable trend in the reform of modern construction, playing an important role in sustainable development and conserving resources. Based on field investigation, questionnaire survey, and the collection and analysis of relevant data, the prefabricated concrete buildings of Chengdu (China) were researched. The development status of prefabricated concrete buildings, production base of prefabricated components, price of precast concrete, and the scale of building construction industry were analyzed and studied. The development obstacles of the prefabricated concrete building were presented and relevant suggestions were provided. The research shows that the production base of prefabricated component is reasonably laid out by forming a radiation circle with the reasonable radius. The price of the prefabricated component is controlled by the average reduction of 1039.8 yuan/m3, and the proportion of prefabricated concrete buildings is adjusted by an increase of 8% to 10% per year. This can promote the development of prefabricated concrete buildings in Chengdu. The incomplete standardization system is the most serious development obstacle, and the establishment of local standards is an effective development proposal. This research provides a reference for the development of prefabricated concrete buildings in large and medium-sized cities.
