Abstract：
Construction technique of cast-in-place concrete cored roof is adopted in a teaching building project of a university. The internal force of side bearing plate of the cored roof is calculated and analyzed and appropriate construction measures are adopted to successfully solve various construction difficulties, such as fragility, horizontal displacement or floating of thin wall hollow tube and difficult control of pipeline position, etc., increase clear height of classroom, improve environmental protection effect and seismic performance, reduce potential fire risk, accelerate construction speed and increase economic benefit.
