Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0036] The invention provides a combined assembled shear wall with a vertical ECC energy dissipation belt, one structural unit of which includes an upper frame beam 8, a lower frame beam 7, a steel tube concrete frame column 1 and a combined shear wall. Such as figure 1 , Figure 5 , Image 6 with Figure 7 As shown, the CFST frame column 1 is composed of a single steel pipe and self-compacting concrete filled in the entire space in the steel pipe. Two CFST frame columns 1 are arranged at the left and right ends of the composite shear wall, parallel to each other inside the composite shear wall. A plurality of partially filled composite core columns 2 spaced apart from each other are arranged in the direction of the steel tube concrete frame column 1 . The partially filled composite core column 2 includes H-shaped steel and ordinary concre...

Abstract

The invention discloses a combination prefabricated shear wall with vertical ECC energy consumption belts and a manufacturing method thereof. Concrete filled steel tube frame columns are arranged on both sides of a shear wall body; a plurality of parallel partially filled composite core columns are arranged in the shear wall body; and the ECC energy consumption belts fill between the frame columnsand the core columns and between the core columns, and after being assembled with upper and lower frame beams, the combination prefabricated shear wall with the vertical ECC energy consumption beltsis formed. Compared with an ordinary concrete filled steel tube frame shear wall and steel plate shear wall, the combination prefabricated shear wall has large lateral resisting stiffness, high bearing capacity, good energy consumption, stable post-seismic performance, slow degradation of bearing capacity and stiffness, multi-line anti-seismic performance and better performance. The construction is convenient, the degree of prefabrication is high, the layout is flexible, and the combination prefabricated shear wall can be used in high-rise or large-scale complex multi-story buildings.

Description

technical field [0001] The invention belongs to the field of anti-seismic buildings, and relates to a combined assembled shear wall with a vertical ECC energy dissipation belt and a manufacturing method. Background technique [0002] Prefabricated buildings are buildings assembled on site with prefabricated components. The development of prefabricated buildings is a major change in the way of construction. It is an important measure to promote the supply-side structural reform and the development of new urbanization. It is conducive to saving resources and energy, reducing construction pollution, improving labor production efficiency and quality and safety levels, and promoting construction. In-depth integration of industry and informatization industrialization, fostering new industries and new kinetic energy, and promoting the resolution of excess capacity. In recent years, my country has actively explored the development of prefabricated buildings, but most of the constru...
