Abstract The steel reinforced concrete hollow roof consists of steel bar, concrete, hard hollow thin-wall members, steel skeleton, etc. Its construction process includes installing steel skeleton with two ends being set on bearing walls; erecting formwork and spreading molding plates or detachable formwork; spreading steel bar and installing built-in fitting; laying hard hollow thin-wall members; depositing, tamping and curing concrete; and detaching formwork. With the advantages of great bearing capacity, high vibration strength and easy construction, the process of the present invention is especially suitable for in-situ deposition of floor board for high-rise building and large span structure.
