METHOD OF CONSTRUCTION PROCESS OF A REINFORCED COMPOUND CONCRETE BEAM CONTAINING DEMOLISHED CONCRETE LUMPS
A method of construction process of a reinforced compound concrete beam containing demolished concrete lumps comprising following steps. Form an I-shaped steel member with a discontinuous top flange by welding a bottom flange plate, a web and two steel plates. Set up a bottom die of the reinforced compound concrete beam. After hoisting the I-shaped steel member with the discontinuous top flange in position, bind longitudinal bars, waist bars and stirrups, and finally set up a side die. (2) Wet the demolished concrete lumps, pour the fresh concrete with a thickness of 20-30 mm inside a cavity formed by the bottom die and the side die, and then put a layer of the wet demolished concrete lumps in a gap between the two steel plates. The two steel plates are two rectangle steel plates or two trapezoid steel plates. Stir artificially so that the demolished concrete lumps are uniformly distributed inside the cavity formed by the bottom die and the side die. Pour a layer of fresh concrete into the cavity and vibrate the demolished concrete lumps and the fresh concrete in the cavity, so that the demolished concrete lumps are uniformly distributed in the fresh concrete. Repeatedly and alternately pour the fresh concrete and the demolished concrete lumps until the cavity is filled.
