Prefabricated steel joint concrete slab-column structure and hoisting method thereof

Abstract

The invention provides a prefabricated steel joint concrete slab-column structure and a hoisting method thereof. The prefabricated steel joint concrete slab-column structure comprises a concrete slab, concrete piles, energy dissipation support units and a plurality of deformation energy dissipation devices, wherein the bottom end of any one of the concrete piles is fixed on the ground foundation or the top end of the next concrete pile, the bottom end of any one of the concrete piles is fixed on the ground foundation or the concrete slab and arranged between every two adjacent concrete piles, and deformation joints are formed between the concrete slab at the top end and any one adjacent concrete pile; the deformation energy dissipation devices are arranged in the deformation joints and at two vertex angles of any one of the energy dissipation support unit. The steelwork joints are arranged at the joint of the concrete piles and the ground foundation or the concrete slab. Prefabrication efficiency is improved, anti-seismic function is realized, construction procedures are simplified, and construction cost is reduced.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a prefabricated assembled steel node concrete slab-column structure and a hoisting method thereof. Background technique [0002] Prefabricated concrete structure is a structural type that conforms to the industrialized production mode of construction, and has the outstanding advantages of standardized design, prefabricated production, and assembled construction. [0003] The structural systems such as prefabricated integral concrete frames, frame-shear walls, and full shear walls that are currently widely used have the following shortcomings or problems: There are still a large number of concrete cast-in-place wet operations during the construction process, the process is complicated, and the construction efficiency is not high. ; The component prefabrication rate is too low (15% to 40%), and it is difficult to increase; the types and specifications of prefabricated compon...

[0003] The structural systems such as prefabricated integral concrete frames, frame-shear walls, and full shear walls that are currently widely used have the following shortcomings or problems: There are still a large number of concrete cast-in-place wet operations during the construction process, the process is complicated, and the construction efficiency is not high. ; The component prefabrication rate is too low (15% to 40%), and it is difficult to increase; the types and specifications of prefabricated components are too many, which increases the cost of factory prefabrication; the construction cost remains high, and it is difficult to promote

[0004] The application of the current prefabricated concrete slab-column structure alleviates the above contradictions to a certain extent, but since the joints between the prefabricated slab and the prefabricated column need sufficient rigidity to improve the lateral resistance of the structure, the joints between the prefabricated slab and the prefabricated column are limited. The force is relatively complex, and assembly design and construction are difficult; in addition, the plate-column structure has limited lateral resistance and is not suitable for the construction of high-rise buildings, and its promotion and application have obvious limitations; Higher, but poor compatibility between structure and enclosure system, low fire resistance and corrosion resistance, high construction cost and other deficiencies, which affect its wide-scale promotion and application
