Liftable supporting leg type elevator shaft construction platform and method

Abstract

The invention discloses a liftable supporting leg type elevator shaft construction platform and method. The construction platform comprises an outer frame, cross beams arranged in the outer frame and a construction platform body consisting of steel plates laid on the outer frame and the cross beams and is characterized in that sleeves are welded to two ends of each cross beam, slidable variable-cross-section supporting legs are arranged in the sleeves, and a group of connecting rods is vertically arranged on each cross beam. Due to the fact that the construction platform is arranged on the structural beams, the height difference of the variable-cross-section supporting legs enable the construction platform to be lower than structural beam plates, reinforcement of an inner side formwork of an elevator shaft is facilitated, and concrete forming quality is ensured. Therefore, the liftable supporting leg type elevator shaft construction platform is simple in operation, quick and convenient to construct and safe and reliable in use, can be constantly lifted according to the height of a constructed building, can effectively improve construction efficiency and shorten a construction period and can be repeatedly used, and construction cost can be saved.

Description

technical field [0001] The invention relates to a construction platform and a construction method of a liftable outrigger type elevator shaft, which belong to the technical field of building construction. Background technique [0002] With the continuous improvement of today's architectural design level, the continuous development of construction technology and the improvement of the requirements for building functions, high-rise and super high-rise buildings continue to emerge. However, when constructing the shear walls of elevator shafts in high-rise and super high-rise buildings, because the inside of the elevator shaft is connected up and down, and the space is narrow, it not only brings various inconveniences to the construction personnel, but also brings greater safety hazards with the increase of floors. .

Problems solved by technology

However, when constructing the shear walls of elevator shafts in high-rise and super high-rise buildings, because the inside of the elevator shaft is connected up and down, and the space is narrow, it not only brings various inconveniences to the construction personnel, but also brings greater safety hazards with the increase of floors.

In order to solve the above problems, the existing elevator shaft shear wall construction method is to build fastener type steel pipe scaffolding in the elevator shaft, and the construction personnel stand on the scaffold to construct the elevator shaft shear wall. However, for high-rise and super high-rise buildings Said that if the above method is used for construction, as the floor continues to rise, it is necessary to continuously increase and build new scaffolding. Not only is it more troublesome to hoist and build steel pipes for scaffolding, it will prolong the construction period and reduce construction efficiency, and the mechanical properties of steel pipes for scaffolding The bearing capacity is limited. When the height of the scaffold exceeds 50m, the steel pipe at the bottom of the scaffold will bear huge pressure, and the stability of the scaffold will deteriorate, posing safety hazards.
