Title: SUPERIMPOSEDLY ASSEMBLED INTEGRAL BASEMENT HAVING COMBINED FLAT SLAB SYSTEM AND BEAM-COLUMN SYSTEM
Abstract:
A superimposedly assembled integral basement having combined flat slab system and beam-column system. The floor (1) of the basement is a full cast-in-situ concrete floor or a precast superimposed floor; and side walls of the basement are precast superimposed sandwich walls (2); several cast-in-situ columns (3) are provided in the middle of the basement, and are fixedly connected with column caps (4) and superimposed beams (11); the roof of the basement uses flat slabs; the flat slabs are integrally connected with the top parts of the precast superimposed sandwich walls (2) of the side walls and the column caps (4) of the cast-in-situ columns (3) by means of cast-in-situ; n negative floors of the basement use precast superimposed slabs, the precast superimposed slabs being integrally connected with the superimposed beams (11) on the cast-in-situ columns (3) by means of cast-in-situ. The basement can be constructed without templates on site, having the advantages of small earthwork volume, low cost, fast construction process, controllable quality, and no environmental pollution caused by the construction of the basement.
