Abstract

The invention discloses a prefabrication integral casting building structure system with cast-in-site haunched beams. The prefabrication integral casting building structure system comprises cast-in-site pillars, the cast-in-site haunched beams, prestress superposed beams, and cast-in-site floor slabs; each prestress superposed beam comprises a prestress prefabrication beam and a cast-in-site part, wherein the prestress prefabrication beam comprises a beam body and a prestress steel stranded wire which is embedded into the beam body and is taken as a main rib; a plurality of form erection holes are formed in the beam body in the longitudinal direction; the cast-in-site haunched beams are connected to an adjacent pillar along one direction; the prestress superposed beams comprise main beams and secondary beams; and the main beams are connected with the adjacent pillar which is vertical to the haunched beams in the other direction, and the secondary beams are connected with the haunched beams. The haunched beams are used as the main beams, so that the middle height of the main beams can be reduced effectively, and pipelines can be arranged on the middle parts of the beams; therefore, the story height of a building can be reduced. Through holes, through which the pipelines can pass, of the middle parts of the main beams can reduce the story height further.

Description

technical field [0001] The invention relates to a building structure system, in particular to a building structure system composed of beams, columns and plates, and a construction method for building the system. Background technique [0002] In the traditional prefabricated cast-in-place structural system, the connection nodes between beams are complex in structure and poor in integrity. In order to solve this problem, the main beam is usually cast-in-place, but there are many construction procedures, and there is no corresponding construction equipment in the construction. Compared with the cast structure, there is no advantage in construction period and cost. In addition, in the general structural design, the direction with large span is the main beam, and the direction with small span is the secondary beam. increase. In addition, the traditional prefabricated integral pouring structure generally adopts laminated slabs, and the connection structure is complicated, the co...
