Description
Technical field
The present invention relates to building engineering field more particularly to a kind of Detachable anchor device formula construction method of suspending scaffold.
Background technique
In recent years, increasing with urban architecture, the form of scaffold is also in diversified development trend, and is overhang
Scaffold holds that job area is big, save material, low cost, set up simple and convenient, safe and reliable and obtain extensive with it
It uses.For traditional suspension scaffold using steel pipe as supporting device, stability is poor, and suspension scaffold is all made of fashioned iron as branch in recent years
It holds, the fixation way of cantilever section steel beam is different, and it is most of to use traditional round steel lantern ring, requirement is typically not capable of when bending,
Construction is inconvenient and stability is poor, and waste is big, and cost input is more, and this method overhangs foot hand using novel dismountable anchor formula
Frame, anchor is detachable, is used in turn, and no waste, input cost is larger, but average unit cost is low after turnover, and safety
Can be strong, ensure that the safety in utilization of outrigger, with good economic efficiency and social benefit have good popularization and use valence
Value.
Summary of the invention
The present invention uses a kind of novel dismountable anchor formula construction method of suspending scaffold, and anchor is detachable,
It is used in turn, no waste, input cost is larger, but average unit cost is low after turnover, and security performance is strong, has ensured the use of outrigger
Safety.
To achieve the goals above, present invention employs following technical solutions:
A kind of Detachable anchor device formula construction method of suspending scaffold is installed solid by making Detachable anchor device
It is scheduled on support shuttering, wait pour concrete, and after concrete reaches setting intensity, starts that overhanging type steel beam is installed, then
Section steel beam is accurately positioned, using Detachable anchor device pressing plate, fashioned iron is securely fixed, then carries out frame body and sets up, is set up
Height is no more than 20 meters, in frame body demolishing process, first removes frame body, unclamps anchor nut, remove pressing plate, hang away type
Steel touches downwards four screw rods with hard object afterwards, then pre-embedded device can remove completely, after centralized collection cleaning, is used in turn.
