Abstract
The invention discloses a kind of construction method of overhanging scaffold, comprise the following steps：A, unwrapping wire is positioned in building structure and the earth anchor that will encorbelment is nuzzled in beam slab in advance；B, beam slab concrete is poured into a mould；C, steel I-beam is arranged on the inside of structural outside layers cage bar, with earth anchor of encorbelmenting it is into T-shaped when full weld connect into cantilever steel girder；D, in cantilever steel girder both ends vertical welding rod；E, start in cantilever steel girder structure along building edge, progressively lay level bridge outward；F, the single-row of scaffold for being assembled ground with tower crane is hung on level bridge；G, pessimistic securit net is completely hung in the outside of scaffold.The scaffold building methodological science of the present invention is reasonable, and I-steel welding is encorbelmented to encorbelment compared to steel wire rope and has higher stability and security, and is mounted and dismounted conveniently, and economic benefit and social benefit are notable.
Description
Technical field
The present invention relates to technical field of buildings, and in particular to a kind of overhanging scaffold
Construction method.
Background technology
In modern architecture work progress, scaffold is a kind of essential auxiliary construction instrument, it may ensure that the safety of work high above the ground, meets the needs that operation, material are banked up and transported.Conventional scaffold building method is console mode scaffold and overhanging scaffold.Console mode scaffold is that disposable tower is set to top, and total height is usually no more than 30 meters, can not meet the needs of skyscraper, and steel pipe and fastener input amount are big, service life length；Overhanging scaffold uses steel wire rope discharging type scaffold mostly, although height of encorbelmenting up to more than 45 meters, exists and sets up the shortcomings such as stability is poor, safety coefficient is low.
The content of the invention
The technical problem to be solved in the present invention is in view of the shortcomings of the prior art, there is provided one
The construction method for the overhanging scaffold that kind is safer, more stable, cost is low.
The present invention adopts the following technical scheme that：
A kind of construction method of overhanging scaffold, comprises the following steps：
A, unwrapping wire is positioned in building structure and the earth anchor that will encorbelment is nuzzled in beam slab in advance；
B, beam slab concrete is poured into a mould, after concrete strength reaches 12Mpa, then carries out the installation of I-steel Cantilever Beams；
C, steel I-beam is arranged on the inside of structural outside layers cage bar, with earth anchor of encorbelmenting it is into T-shaped when full weld connect into cantilever steel girder；
Multiple slidable suspension ring are set on cantilever steel girder both ends vertical welding rod, rod d,；
E, start in cantilever steel girder structure along building edge, progressively lay level bridge outward；
F, the single-row of scaffold for being assembled ground with tower crane is hung on level bridge, and is connected with right-angle coupler and suspension ring；
G, pessimistic securit net is completely hung in the outside of scaffold.
The single-row of scaffold steel pipe is using long 5m, diameter 50mm, the mm of wall thickness 3.6 steel pipe.
In the junction of cantilever steel girder and rod reinforcement repair welding is carried out with triangular steel.
Compared with prior art, beneficial effects of the present invention are as follows：
The scaffold building methodological science of the present invention is reasonable, and I-steel welding is encorbelmented to encorbelment compared to steel wire rope and has higher stability and security, and is mounted and dismounted conveniently, and economic benefit and social benefit are notable.
Embodiment
The invention will be further described with reference to embodiments.
A kind of construction method of overhanging scaffold of the present invention, comprises the following steps：
A, unwrapping wire is positioned in building structure and the earth anchor that will encorbelment is nuzzled in beam slab in advance；
B, beam slab concrete is poured into a mould, after concrete strength reaches 12Mpa, then carries out the installation of I-steel Cantilever Beams；
C, steel I-beam is arranged on the inside of structural outside layers cage bar, with earth anchor of encorbelmenting it is into T-shaped when full weld connect into cantilever steel girder；
D, in the vertical spot welding rod in cantilever steel girder both ends, and reinforcement repair welding is carried out with triangular steel in the top and the bottom of junction, left and right portion, multiple slidable suspension ring is set on rod；
E, start in cantilever steel girder structure along building edge, progressively lay level bridge outward；
F, the single-row of scaffold for being assembled ground with tower crane is hung on level bridge, and is connected with right-angle coupler and suspension ring, and the single-row of scaffold steel pipe is using long 5m, diameter 50mm, the mm of wall thickness 3.6 steel pipe；
G, pessimistic securit net is completely hung in the outside of scaffold.
Claims (3)
