CONCRETE FLOOR STRUCTURE AND METHOD OF CONSTRUCTING THE SAME

摘要

To provide a concrete floor structure capable of preventing cracking from occurring due to composite factors and preventing opening and cracking from occurring in a concrete construction joint part even in a floor slab having a large area and relatively greater thickness in an industrial facility; and a method of constructing the concrete floor structure. The concrete floor structure is formed by alternately disposing compartments in which concretes with different expansion factors are installed. The compartments in which the concretes with different expansion factors is installed, for example, the compartment in which the concrete with no an expansion material is installed and the compartment in which the concrete with the expansion material is installed.
