Beam-slab integrated precast concrete structure and construction method

Abstract

The invention relates to a beam-slab integrated precast concrete structure and a construction method. The beam-slab integrated precast concrete structure comprises precast beam-slab units, precast laminated frame beams, concrete stand columns and a cast-in-place concrete surface layer; the concrete stand columns are distributed in an array mode, and bearing pieces A and B are arranged at the upper ends of the concrete stand columns; the two ends of the precast laminated frame beams are erected at the upper ends of the adjacent concrete stand columns correspondingly, and each precast laminated frame beam is provided with a bearing piece C; the precast beam-slab units are arranged between the two parallel precast laminated frame beams; the precast beam-slab units, the top surfaces of the precast laminated frame beams and all beam column joints are cast in place with concrete to form the cast-in-place concrete surface layer; the construction method comprises the steps that firstly, array construction of the concrete stand columns is completed; and then the precast beam-slab units and the precast laminated frame beams are installed in order, and finally the cast-in-place concrete surface layer is poured. The beam-slab integrated precast concrete structure and the construction method have the advantages that support-free and mold-free construction of precast concrete structure on-site construction is achieved, the construction speed can be remarkably increased, and the on-site construction cost is remarkably reduced.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a beam-slab integrated prefabricated concrete structure and a construction method. Background technique [0002] In recent years, prefabricated buildings have developed rapidly in our country. The State Council issued the "Guiding Opinions on Vigorously Developing Prefabricated Buildings", further clarifying that green buildings and building materials should be actively promoted in the future, and strive to make prefabricated buildings account for 30% of new buildings in about 10 years. [0003] When existing prefabricated concrete buildings use laminated floor slabs and prefabricated composite beams, support is usually required during the construction phase. When the floor height is large, the support system is complex and expensive. Therefore, in order to speed up the construction speed and reduce the cost of project measures, it is of great practical value to realize the f...
