Assembly type additional lift shaft structure adapting to jacking construction

Abstract

The invention discloses an assembly type additional lift shaft structure adapting to jacking construction. The assembly type additional lift shaft structure adapting to jacking construction comprisesa foundation, a prefabricated steel frame supporting structure, a light curtain wall envelop structure and a roof. The prefabricated steel frame supporting structure comprises a first layer frame, a plurality of standard layer frames and a top layer frame. Each layer frame comprises four or more stand columns, wherein the positions of the stand columns are set in a face-to-face mode. The bottom ends of the first layer stand columns are connected with embedded parts of the foundation, and the stand columns of the layer frames are connected in sequence in an end-to-end mode. A transverse beam isconnected between the bottoms of every two adjacent stand columns of the same standard layer frame so that a U-shaped structure can be formed. Transverse beams are arranged between the tops of everytwo adjacent stand columns of the top layer frame and between the bottoms of every two adjacent stand columns of the top layer frame. The exterior of each layer frame supporting structure and the corresponding portion of the light curtain wall envelop structure are combined to form an independent shaft structure unit, and jacking is accomplished by the layer structure units. A plurality of flexible connecting components are arranged between the prefabricated steel frame supporting structure and an existing building. The assembly type additional lift shaft structure adapting to jacking construction is high in degree of standardization, light in weight of each single component and low in component specification, and coincides with the development trend of building industrialization, standardization and assembly.

Description

technical field [0001] The invention relates to a prefabricated building structure, in particular to an existing multi-storey building plus an elevator shaft structure which is prefabricated by standardization in a factory and assembled in sections on site. Background technique [0002] According to the standards established by the United Nations in 1956, "Population Aging and Its Socioeconomic Consequences", when the number of people aged 65 and above accounts for more than 7% of the total population in a country or region, it means that the country or region has entered the aging process. In 1982, the World Congress on Aging in Vienna determined that the elderly population aged 60 and above accounted for more than 10% of the total population, which means that the country or region has entered a serious aging process. [0003] According to the results of the fifth census in 2000, the elderly population over 65 years old in my country has reached 88.11 million, accounting fo...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the problems of the existing prefabricated multi-storey building plus elevator shaft project, the construction period is long, there are many high-altitude operations, great interference to residents, limited site space, potential safety hazards, many operating links, and complex technologies, etc., the present invention provides a An assembled elevator shaft structure suitable for jacking construction. The elevator shaft structure occupies less land, has a short construction period, has little interference with residents, avoids high-altitude operations, and does not need large-scale lifting equipment. It is convenient, safe and fast
