Problems solved by technology

[0002] At present, the traditional high-altitude prestressed tensioning of the cover beam is to use the climbing vehicle as the manned and loaded platform throughout the whole process, and to complete the tensioning construction work with the truck hoisting jack. This construction method requires a lot of manpower and material resources, and there are many Big safety risks, cumbersome construction procedures, more on-site operations, and slower construction progress
The disadvantages of cumbersome construction procedures, many safety hazards and slow progress brought about by the traditional climbing car and truck crane to complete the high-altitude prestressed tensioning of the cover beam

Abstract

The invention relates to a suspended self-locking type prestress tensioning platform, and belongs to the technical field of construction equipment. The prestress tensioning platform is suspended on ear walls at two ends of a bent cap, is used for performing prestressed tensioning on the bent cap, and comprises a trapezoidal frame and a platform panel positioned at the bottom of the frame, a safetyprotection plate is arranged on the back surface of the frame, safety guardrails are arranged on two side surfaces of the frame, and a balance support top block is arranged at the lower part of one surface, facing the ear walls of the frame; the top of the face, facing the ear walls, of the frame extends outwards to form an extending section, the end of the extending section is provided with a self-locking hook used for being hooked to stop blocks of the ear walls, and the top of the frame is further provided with a guide rail which is provided with a chain block used for hanging a jack. Theplatform has the advantages of being simple and convenient to mount and dismount, safe and reliable in structure, convenient to suspend and operate by personnel, free of influence of the ground clearance and high in applicability.

Description

technical field [0001] The invention relates to a suspended self-locking prestressed tension platform, which belongs to the technical field of construction equipment. Background technique [0002] At present, the traditional high-altitude prestressed tensioning of the cover beam is to use the climbing vehicle as the manned and loaded platform throughout the whole process, and to complete the tensioning construction work with the truck hoisting jack. This construction method requires a lot of manpower and material resources, and there are many Big safety risks, cumbersome construction procedures, more on-site operations, and slower construction progress. The traditional high-altitude climbing vehicle and truck crane complete the high-altitude prestressed tensioning of the cover beam, which has the disadvantages of cumbersome construction procedures, many safety hazards, and slow progress. Contents of the invention [0003] In order to solve the above problems, the object o...
