REINFORCED STRUCTURE OF SLAB IN EXISTING BUILDING

PROBLEM TO BE SOLVED: To provide a reinforced structure of a slab in the low priced and simple existing building. SOLUTION: The reinforced structure 1 mounts a truss bar 3 on the lower face of the existing slab 2 with a fixed plate 4, the truss bar 3 is jointly formed of one upper end bar (top bar) 5 placed on the tip of a triangle and two lower end bars (bottom bar) 6 with a corrugated lattice bar 7, and the upper end bar 5 is mounted on the lower face of the slab 2 in a state to turn it to the lower side. Steel plates 8 and 9 as the fixed plate are welded and connected into the lower end bars 6 of the truss bar 3, the large steel plate 8 connected to both end sides and the lengthwise small steel plate 9 welded among these ones are mounted on the lower face of the slab 2 with an anchor bolt 10. These steel plates 8 and 9 can be adhered with, for example, a longer useable time type two component epoxy resin other than the anchor bolt 10, both of them can be used also for making adherence/connection, at the same time, the large steel plate 8 is connected with the anchor bolt 10, and the small steel plate 9 can be also adhered with an adhesive.
