Precast concrete module hoistway for additionally arranging elevator and construction method

Abstract

The invention provides a precast concrete module hoistway for additionally arranging an elevator and a construction method. The precast concrete module hoistway is characterized in that a foundation mat poured on site and a foundation raft are sequentially provided with a foundation joint connected with the foundation raft, a first-layer joint connected with the foundation joint, an adjustable joint connected with the first-layer joint, a standard joint connected with the adjustable joint and a top-layer joint connected with the standard joint from bottom to top, and all modules are reinforced concrete precast components; each module is at least provided with a hoistway room used for installing the elevator, and the first-layer joint module and the standard joint module are further provided with aisle rooms communicating the hoistway rooms with a main building; and the foundation joint module and the foundation raft are leveled through mortar cushion blocks and connected through embedded bolts, all the modules are combined and fixed through positioning key bolts, and the positioning key bolt combination and fixation comprise shear-resistant positioning key and tensile-resistant embedded bolt connection. The precast concrete module hoistway has the beneficial technical effects of being small in site construction site potential safety hazard, short in construction period and low in construction cost.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to the project of adding elevators to old buildings, and in particular to a modular concrete elevator shaft and a construction method. Background technique [0002] The multi-storey buildings built from the 1950s to the 1990s did not have elevator equipment. As the population in these multi-storey buildings ages, daily going up and down stairs makes the elderly daunting. For those who are weak or need to use wheelchairs Residents, travel is even more difficult. [0003] As the city enters the deep aging process, people's demand for a better life continues to increase. The installation of elevators in multi-storey housing has become a major "just need". The gage is large. [0004] When installing an elevator in an old-fashioned residence, the elevator shaft can only be reinstalled on the outside of the outer wall. The traditional method is to use the steel structure on-site ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that there are large potential safety hazards at the construction site, long construction period and high construction cost in the prior art.
