METHOD FOR ERECTION OF FLOOR SLAB WITH PARTIAL LEVEL DIFFERENCE AND BEAM TYPE FRAME USED FOR THE METHOD

摘要

PROBLEM TO BE SOLVED: To form a beam which can display a sufficient strength, with excellent operability, in a beam building which makes it possible to ensure an underfloor space or to lay various machines in a manner of floor concealment. ;SOLUTION: In a joining part of a beam 3 and a floor slab 1 with partial level difference, a lower corner metal material 9 forming a lower haunch reinforcing part 8 is provided continuously so that it is suspended toward the upper side of the floor slab 1 of a beam frame 6. The lower end of this lower corner metal material 9 is extended in parallel with the base part of the floor slab 1 so that it constitutes a reference part 9a, and a protuberance of concrete on the upper side of the floor slab 1 is corrected by troweling the reference part 9a after the concrete is placed.;COPYRIGHT: (C)1997,JPO
