Construction method for high-rise reinforced concrete elevator shaft

Abstract

The invention relates to a construction method for a high-rise reinforced concrete elevator shaft. The construction method comprises the steps: step one, a movable platform is assembled; step two, the movable platform is lifted and installed in position by using a tower crane after completing construction of a first floor elevator shaft; step three, the movable platform which is lifted and installed in position is arranged in a tilted mode, a scaffold is vertically fixedly arranged on the tilted movable platform, an overturning lap beam is arranged on the wall of the elevator shaft in a lap joint mode, and the overturning lap beam is clamped by a limiting clamping plate; step four, the scaffold is fixed firmly; step five, a formwork of the elevator shaft is installed, and the formwork is erected on a horizontal-bar-positional continuous wood beam of the shaft wall; step six, concrete construction is carried out on the elevator shaft; step seven, the formwork of the elevator shaft is removed; step eight, the movable platform is installed in position; step nine, repeating the step four to eight until the construction of the high-rise reinforced concrete elevator shaft is completed. According to the construction method for the high-rise reinforced concrete elevator shaft, the construction method can be utilized repeatedly, the usage of the formwork is effectively reduced, the manpower input is lowered, the cross-operation of a formwork worker and a scaffolder is reduced, and the project cost is lowered.

Description

technical field [0001] The invention belongs to the field of high-rise building elevator shafts, in particular to a construction method for high-rise reinforced concrete elevator shafts. Background technique [0002] With the development of urbanization, problems such as population expansion, housing difficulties, and land shortage have become increasingly prominent, and there are more and more high-rise and super high-rise buildings. In the construction of reinforced concrete elevator shafts in high-rise or super high-rise buildings, the common practice is: from the high-rise The pit of the concrete elevator shaft starts to erect the scaffolding in the shaft. Generally, the erection height has passed the safety calculation, but shall not exceed 50m. Section erected scaffolding. According to conventional construction methods, safety protection is difficult to achieve, and at the same time, a large amount of labor and a large amount of turnover materials are invested, which ...
