Elevator shaft section steel construction operation platform

Abstract

The invention discloses a lift shaft section steel construction operating platform which is mainly composed of a base and platform frames installed on the base. The base includes two pieces of parallel H-shaped oblique support section steel, and two section steel transverse linkage beams are arranged between the two pieces of oblique support section steel. The higher end of each piece of oblique support section steel is supported on one wall of a lift shaft, a corbel is additionally arranged at the lower end of each piece of oblique support section steel and supported on a lift shaft door opening external corner. The positions of flange upper surface, close to the two ends, of each piece of oblique support section steel are respectively provided with a platform frame locating column, the platform frames are constructed with fastener-style steel pipes, and platform frame locating columns are sleeved with steel pipes which form the four legs of the platform frames. Due to the fact that the lift shaft section steel construction operating platform is high in strength, the safety of operating personnel can be more guaranteed; besides, the lift shaft section steel construction operating platform is applicable to lift shafts with different inner space sizes, thereby being strong in universality.

Description

technical field [0001] The invention relates to the improvement of an elevator shaft operation platform, in particular to an elevator shaft section steel construction operation platform, which belongs to the technical field of elevator shaft construction. Background technique [0002] In the construction of elevator shafts in high-rise buildings, scaffolding needs to be built in the shaft to form an operating platform. The operating platform is mainly composed of a base and a platform frame installed on the base. The base is supported on the well wall and the door opening to bear all the forces. The current elevator hoistway operation platform is built with a large number of steel pipe fasteners, including the base and the platform frame, which are mainly made of steel pipes. The hoistway scaffolding uses steel pipes to be slanted and the lower part uses horizontal rods to support the elevator shaft wall as the force support of the operating platform. This support method h...

AI Technical Summary

Problems solved by technology

The rigidity of this support method is relatively poor, and the force on the fastener is large, so there are certain requirements for workers to operate the fastener fastening

Moreover, the fasteners are frequently turned over, easily contaminated and damaged, the quality cannot be guaranteed, and the movement of the frame is inconvenient

During the construction process, there have been many safety production accidents in which the operating platform of the elevator shaft collapsed and caused death by using this support method.
