Description

Building structure overhanging scaffold external corner assembling type frame body device
Technical field
Building structure overhanging scaffold external corner assembling type frame body device, belongs to building external scaffolding technical field of construction.
Background technology
Scaffold is existing well known for the construction, finishing etc. of outside vertical surface of building, and in highrise building, we more use overhanging scaffold go along with sb. to guard him to carry out alien invasion and construct.Overhanging scaffold refers to the scaffold of frame structure off-load on the rigidity Cantilever Beams being attached to building structure, and need for the operation of the main body in building operations or fitting-out work and security protection thereof, every section of scaffolding height must not be greater than 24m.Accommodation is high-rise or Super High in reinforced concrete structure, steel work, and the main body in building operations or the operation of fitting-out work and security protection thereof need.
The overhanging scaffold of this prior art needs to adopt many Cantilever Beams to be arranged to radially support upper falsework vertical rod at building structure bead angle place, arranges very loaded down with trivial details, calculating also corresponding complexity.This needs construction technical staff that experience is very abundant according to specification and stress condition in conjunction with the careful layout of on-the-spot structure, installed by scheme prescribes position by veteran scaffold installer girder of carefully encorbelmenting again, set up steel pipe scaffold again, need to drop into a large amount of manpower and materials, and there is very large potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is: provide one to overcome prior art Problems existing, effectively can solve overhanging scaffold arranges very complicated loaded down with trivial details, the problem such as security reliability is low a kind of building structure overhanging scaffold external corner assembling type frame body device at building structure external corner part.
The technical solution adopted for the present invention to solve the technical problems is: this building structure overhanging scaffold external corner assembling type frame body device by building structure, bearing support, double nut, through-wall bolt, L-type external corner scaffold bottom tray, external corner assembling type frame body structure, suspending bars, draw board to form; Fix with through-wall bolt anchoring between bearing support and the building structure first floor, and reinforce with suspending bars fixing between the building structure second layer; Bearing support upper berth L-type external corner scaffold bottom tray also sets up external corner assembling type frame body structure; The conventional overhanging scaffold support body at this device two ends is erected at girder top of encorbelmenting, and is connected with adopting to overlap between external corner assembling type frame body structure.Bearing support two ends scaffold cantilever span is not more than 2000mm, and is fixed by embedded wall penetration bolt between the building structure first floor, and through-wall bolt two ends double nut is tightened; Bearing support is connected with building structure second layer suspending bars, and suspending bars is connected one end with being welded to connect with bearing support, is connected one end through-wall bolt and double nut is tightened with building structure.L-type external corner scaffold bottom tray is factory's customization, is spliced with the thick profiled sheet of 3mm.External corner assembling type frame body structure is made up of leger, little cross bar, vertical rod, hound; Four vertical rods are set up on bearing support top, and reinforce fixing with hound, are equipped with leger and little cross bar, form a main couple structure.External corner assembling type frame body top fixed connection point is the attached wall measure of building structure except the first floor between top all the other which floor and external corner assembling type frame body structures, being weldingly fixed on by short steel pipes one end draws on board, the other end two fastener and external corner assembling type frame body anatomical connectivity.External corner assembling type frame body first floor fixed connection point is the reinforcement measure between the building structure first floor and bearing support, and be weldingly fixed on bearing support by short steel pipes one end, the other end welds with through-wall bolt.
Concrete construction method of the present invention:
1.establishment special construction plan.
After building structure concrete strength reaches design strength, bearing support is installed.
After bearing support installation, suspending bars is installed, and sets up main couple, then set up rotation angle position frame structure.
Lay according to design attitude girder of encorbelmenting, conventional overhanging scaffold support body is installed.
Successively up set up, support body height is no more than five layers; Every layer of major structure of construction all needs to be connected firmly with short steel pipes and main couple.
Compared with prior art, the beneficial effect that the present invention has is: it is simple that this building structure overhanging scaffold external corner assembling type frame body device and construction method have construction technique principle, set up easy, batch production makes, the reliable feature of quality safety, and conventional overhanging scaffold can be simplified construct at the radiation of external corner part complexity, save the use amount of girder of encorbelmenting in a large number, improve the security and stability of whole support body, assembled very easy.
