Supporting bracket, steel platform and steel platform control system and operation method

Abstract

The invention provides a supporting bracket, a steel platform and a steel platform control system and operation method. The supporting bracket includes a bracket body, and the bracket body is providedwith a supporting matching surface. The supporting matching surface is provided with a locking part, and the locking part can be embedded into a groove of a bracket pre-embedded case so that the fixation of the positions of the supporting bracket and the bracket pre-embedded case can be ensured when the bracket body extends into the bracket pre-embedded case. According to the supporting bracket,the steel platform and the steel platform control system and operation method, the stability of the position of the supporting bracket which extends into the pre-embedded bracket case can be ensured,and the construction safety risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a supporting corbel, a steel platform, a steel platform control system and an operation method. Background technique [0002] At present, there are more and more super high-rise buildings at home and abroad. Due to the excellent mechanical performance of the rigid outer frame-core tube structure, the construction process of the core tube first and the outer frame lagging behind is often used in the process of super high-rise buildings to open the working surface and speed up construction. schedule. At present, the aerial work platform suitable for super high-rise core tube construction mainly includes hydraulic climbing formwork components and integral climbing steel platform (referred to as steel platform). Among them, the steel platform formwork equipment is composed of the top steel platform beam, inner cylinder frame, external hanger, formwork syste...

AI Technical Summary

Problems solved by technology

The steel platform is supported by placing the outstretched support corbel in the reserved hole in the wall (that is, the embedded corbel box). The pre-embedded corbel box in the wall + the telescopic corbel support of the steel platform has the advantages of simple force, It has the advantages of simple construction and operation, but there are deficiencies such as low degree of automation and low safety, which are mainly reflected in:

[0003] (1) Before the steel platform climbs or after climbing into place, the real-time state of the extension or retraction of the supporting corbel needs to be measured or checked manually. The working environment is poor under the high-altitude lifting state, manual operation is easy to make mistakes, and a lot of manpower is required;

[0004] (2) The supporting corbels of the steel platform are placed in the reserved holes, and the horizontal force only depends on the horizontal friction force, which cannot effectively deal with the horizontal force borne by the steel platform or the shaking of the steel platform in extreme cases, posing safety hazards;

[0005] (3) After the steel platform climbs into place, it is impossible to accurately determine the vertical distance between the supporting corbels and the reserved holes in each steel platform tube frame, which may easily cause the contact force of local corbels to be too large momentarily when the steel platform falls, posing a safety hazard ;

[0006] (4) The steel platform is supported by multiple supporting corbels at the same time, and the construction cannot ensure that the reserved holes are at the same elevation, and the inconsistent elevation of the supporting corbels causes additional internal stress, and the pressure of local support corbels is too large;

[0007] (5) The steel platform support corbel is an important stress-bearing component, and its stress state and safety determine the safety of the steel platform formwork equipment, but there is currently a lack of effective monitoring, and the safety hazards are more prominent
