<p><P>PROBLEM TO BE SOLVED: To obtain a composite beam capable of dispensing with a binder, a building, and a construction method for the composite beam. <P>SOLUTION: A composite beam 20 includes: an H-shaped steel beam 22; web concrete 34 which is constructed integrally with a low flange 26 at a spacing with respect to an upper flange 24 of the beam 22; precast slab concrete 16 which has an end erected on the top surface of the web concrete 34; and a filler 30 which is infilled between the web concrete 34 and the upper flange 24 and which makes a top surface of the upper flange 24 flush with a finished surface of the slab concrete 16. In this case, since the composite beam 20 has the slab concrete 16 made in a precast manner, the composite beam 20 can bear a load acting on the slab concrete 16, even in the absence of the binder, for example, by presetting the thickness of the slab concrete 16 great enough to bear the load. Thus, the binder can be dispensed with in construction of a building 10. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
