Implementation plan for indoor installation of elevators

The construction was implemented in three phases:

Install outdoor fire pedestrian stairs:

The actual size of the site room, the on-site pre-embedded connectors, the processing of steel ladder components in the factory, and the on-site assembly of steel stairs, this process takes about 10 days.

Cut off the original stairway and half-storey rest platform from top to bottom. At the same time, install the steel structure corridor (that is, the stair front hall floor) layer by layer to connect with the outdoor fire ladder to solve the problem of residents going up and down during the construction period. . It takes 1 day for each floor to be demolished, and the demolished components are transported out of the building through the unremoved stairs on the lower floor. Install the steel structure corridor on the second day (the steel corridor size is measured in advance, processed in the factory, and the connectors are pre-embedded on site). Since the steel structure corridor does not need to be installed on the first floor, the impact on the residents on the first floor is only 1 In one day, the impact of residents on other levels is 2 days. Residents can live in relatives and friends, or rent hotels.

Elevator shaft construction, elevator shaft enclosure, elevator installation, this process takes about 20 days.

The above total construction period will take about 2 months.

Note: Although the impact of this construction implementation plan on the residents is minimized, it still has some impact. In the current situation where the residents on the upper and lower floors of the elevator are not in agreement and cause great conflicts, it is very difficult for the lower-level owners to accept the plan. Big. Therefore, it is recommended that the government introduce a policy to force this work in the name of public safety, and not to fail to install it because of individual owners’ opposition. This will enable the installation of elevators in old buildings to be implemented quickly and comprehensively.
