Jacking construction method for assembled-type external elevator shaftway structure

Abstract

The invention discloses a jacking construction method for an assembled-type external elevator shaftway structure. The jacking construction method comprises the steps that a foundation pit is excavated, and reinforced concrete foundations and pre-buried connecting components are made; a jacking guiding device is mounted on an existing building, and a jacking device is mounted at the bottom of the foundations; a jacking monitoring device is mounted on an assembled elevator shaftway top layer structure unit to conduct jacking operation of the top layer structure unit, the jacking operation stateis monitored in real time, and torsion or inclination of the structure is prevented cautiously; assembling and jacking of structure units of all standard layers are conducted in sequence, and a first-layer structure frame is mounted; equipment is dismounted, and an elevator shaftway and the existing building are connected through flexible connecting components layer by layer; construction of a roof, all layers of floors, partition plates and the first layer is conducted; and finally, an elevator is mounted. By adopting the jacking construction method, the occupied area is small, the period isshort, the efficiency is high, labor force is saved, heavy transportation vehicles and large lifting equipment are not needed, a scaffold does not need to be set up on site, and high-attitude operation and the influence on the daily life of residents can be reduced significantly.

Description

technical field [0001] The invention relates to the construction of a prefabricated building structure, in particular to a construction method of factory standardized prefabrication and on-site sub-assembly of an existing multi-storey building plus an elevator shaft structure. 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 mi...

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 A jacking construction method with an assembled elevator shaft structure, which occupies a small space, has a short construction period, has little interference to residents, avoids high-altitude operations, and does not require large-scale lifting equipment. It is convenient, safe and fast
