FILL CONCRETE LEAKAGE PREVENTION STRUCTURE OF STEEL CONCRETE COMPOSITE FLOOR SLAB

摘要

PROBLEM TO BE SOLVED: To surely prevent the leakage of a fill concrete in the case of filling without greatly raising manufacturing/construction costs for a steel concrete composite floor slab formed by filling the inside of a steel shell panel having an opening in a main girder position with the fill concrete. ;SOLUTION: A sealing member 3 continued in the direction of the axis of a main girder 1 is provided by holding an opening 10 of a base steel plate 7 between the base steel plate 7 and a main girder 1. A projection 4 continued in the direction of the axis of the main girder 1 is provided in the lower surface of the base steel plate 7 coming into contact with the sealing member 3 or the upper surface of the main girder 1 or both of them. The sealing member 3 is fixed to the base steel plate 7 by cutting it into the projection 4, and no gap occurs between the sealing member 3 and projection 4 accordingly. By the constitution, the sealing member 3 can be prevented from slipping away or falling down from the lower surface of a composite floor slab 2 by infilled pressure of a fill concrete 6. The leakage of the unsolidified fill concrete 6 can be prevented.;COPYRIGHT: (C)2000,JPO
