Description

Self-climbing construction system for elevator shaft construction engineering

Technical Field

The present invention relates to an elevator system for construction of building engineering, and more particularly, to a self-climbing construction system for construction of an elevator hoistway.

Background

At present, in building construction sites, hoistway type construction elevators have been widely used. The existing hoistway type construction elevator is constructed and operated based on a hoistway, a car of the elevator is operated in the hoistway, the periphery of the car is protected by the hoistway, and meanwhile, the counterweight-traction machine is used as power, so that the risks of falling, roof-rushing and tipping are fundamentally solved, and various defects caused by the externally hung construction elevator can be effectively avoided.

In the building construction process, along with the continuous rising of the construction building, the integral height of the well type construction elevator needs to be lifted. Specifically, the height of the hoistway is increased first, and then the elevator machine room provided with the counterweight-hoisting machine is also required to be lifted to a position at the top of the hoistway.

The current problems are:

1) The current method for lifting the elevator machine room comprises the following steps: and a lifting device such as an automobile crane, a winch and the like is additionally arranged. After the construction of the high-rise well is completed, the automobile crane is used for lifting the elevator machine room outside the building body; or hoisting the winch to a high-rise machine room by using equipment such as manpower or a hoist and the like for arrangement, and hoisting the elevator machine room after the arrangement is completed; in the lifting mode, the height of the automobile suspension is limited, so that a high-rise or super high-rise building cannot be used, and a great deal of time is consumed for manual setting, so that the construction progress of the building is influenced;

2) The top layer of the well is generally on the same layer as the construction layer, and the traction machine room is also on the same layer, so that constructors cannot directly go to the construction layer. The current construction method for constructing the well is that constructors tie up steel bars and manually support the formwork, generally using wood formworks, and the formwork and the wall on the same floor are simultaneously performed, grouting is performed after the formwork is supported, and manual demoulding is performed after the grouting is solidified. The construction method has slower speed of constructing the well, thereby greatly delaying the construction progress; moreover, as constructors manually support the forms, the wood forms need to be manually carried and fixed and bundled, so that the construction risk of the well construction is increased;

3) When the elevator machine room 1 is lifted up, the tongue holes 21 on the shaft 2 below the elevator machine room are not needed, and the tongue holes 21 are filled and sealed according to the requirements of building construction operation. However, there is currently no relevant work platform to support the operator in performing such work.
