Description
Technical field
The present invention relates to building engineering field, particularly a kind of suspension cable scaffold of constructing for high-rise roof structure.
Background technology
In the construction of traditional roof, normally set up scaffold in the below on roof to be onstructed, after band scaffold is all built, then carry out the construction on roof.But, along with the progress of science and technology, the diversification of human society demand, and the pursuit to building aesthetic, various highrise building constantly emerges in large numbers, and cause the height of its roof structure also to increase, particularly the dome structure of some superelevation super larges is constantly used in architectural design thereupon.
In above-mentioned these highly higher roof structures construction, the form of construction work that scaffold forms operation platform is set up according to common at present, so first then need the scaffolding steel pipe of enormous amount, then a huge scaffold is set up by a large amount of artificial and plant equipment, on scaffold, laying construction platform is constructed to roof structure again, this construction method not only needs a large amount of artificial, but also need higher construction cost, particularly need longer construction period, so directly delayed programming and engineering cost.
And for the dome structure in super highrise building, it has highly been difficult to adopt the form of construction work setting up scaffold from ground, so usually adopt the lifting appliances such as tower crane to construct, but this form of construction work also exists again construction speed slowly, and the deficiency of workman's construction environment danger.
So, need badly at present and a kind ofly can be applicable to the construction of highly higher roof structure, and can construction cost be saved, shorten the device of construction period.
Summary of the invention
The object of the invention is to: for the problems referred to above existed in existing roof structure building operations, provide a kind of and can be applicable to highly higher roof structure construction, and can construction cost be saved, shorten the device of construction period.
To achieve these goals, the technical solution used in the present invention is:
A kind of suspension cable scaffold of constructing for high-rise roof structure, include scaffold and the operation platform on described scaffold is set, the matching form of described operation platform and roof structure closes, described scaffold is connected with the suspension cable of its weight of carrying, described suspension cable is riveted on the structure below described roof structure.Suspension cable is established by the structure pull-up below roof structure, scaffold is arranged on suspension cable, the height can built according to actual roof structure arranges the setting height(from bottom) of suspension cable, and then is arranged on suspension cable by scaffold and operation platform, now, in vacant state below scaffold, so be different from traditional scaffold, the suspension cable scaffold of this programme does not need spelling from ground, first the consumption decreasing scaffolding steel pipe, has saved cost and engineering quantity; Reduce because scaffold takes up room, and other work items caused are delayed the stand-by period; The more important thing is in addition, in the construction of highly higher roof structure, being difficult to set up scaffold to roof structure from ground, the suspension cable scaffold of this programme still can be suitable for, so breach the restriction of roof structure height.
As preferably, described suspension cable comprises some spaced apart and main drag-lines be parallel to each other, spaced apart with some and vertical with described main drag-line registration wire, on all each self-corresponding structure be fixed on below described roof structure in described main drag-line two ends and registration wire two ends, the lower end of the vertical rod of described scaffold is arranged on the node that described main drag-line and registration wire intersect.Carry out support scaffolding by mutual vertical main drag-line and registration wire, the vertical rod of scaffold is arranged on the node that main drag-line and registration wire intersect, and ensure that the reliability of suspension cable support scaffolding.
