Description

Technical Field

[0001] The invention relates to an assembled building balcony structure, belonging to the technical field of building industrialization and assembled concrete frame structure construction. Background Art

[0002] Prefabricated structures can save energy, water, and materials, significantly reduce construction waste, reduce noise pollution, reduce labor and intensity, effectively improve the construction environment, and improve the quality of the project. They are structures worthy of vigorous promotion. Based on research and application experience at home and abroad, prefabricated frame structures, prefabricated shear wall structures, and prefabricated frame-cast-in-place shear wall (core tube) structural systems can be used. The load-bearing components in the structure can all be prefabricated components or a combination of prefabricated and cast-in-place components. Among them, prefabricated shear wall structures can be divided into fully prefabricated shear wall structures, partially prefabricated shear wall structures, and multi-layer shear wall structures with appropriately reduced structural performance requirements. The frames, beams, and columns in prefabricated frame structures and prefabricated frame-cast-in-place shear wall (core tube) structures are all prefabricated components, and the nodes and joints between the load-bearing components are designed and constructed in accordance with the requirements of the same cast-in-place structure. This structural system has the same performance as the cast-in-place structure, and the applicable height, seismic grade, and design method of the structure are basically the same as those of the cast-in-place structure. Fully prefabricated shear wall structure refers to the shear wall that is assembled with prefabricated components. The joints between prefabricated walls are basically equivalent to cast-in-place structures or slightly lower than cast-in-place structures. It is necessary to meet the bearing capacity and deformation requirements of the joints through design calculations, and consider the influence of the joints in the overall structural analysis. The prefabrication rate of this structural system is high, but the connection structure of the joints is relatively complex and the construction is difficult. It is difficult to ensure that it is completely equivalent to the cast-in-place shear wall structure. The current research and engineering practice are not sufficient, and further research is needed to promote its application in earthquake zones. Summary of the invention
