Compared with the prior art, the utility model has the advantages that:

1. Through innovative support and hard pull rod design, the node area to which the odd-even layer attaching device cannot attach is successfully modified. Under the condition that the building structure is complex and changeable, the attached lifting scaffold can be firmly attached to the building main body, so that the unstable attaching factors caused by special structures are greatly reduced, and the possibility of potential safety hazards of the scaffold body is fundamentally reduced.

2. The combined structure of the support and the hard pull rod not only realizes effective installation of the attachment device, but also enhances the overall structural stability of the scaffold. When facing wind load, earthquake load and various dynamic loads in the construction process, the scaffold can better disperse and transfer load, so that the stress of the scaffold body is more uniform, and the phenomenon of local stress concentration is reduced. Compared with the traditional treatment mode, the technical scheme of the utility model can obviously improve the deformation resistance and the anti-overturning capacity of the scaffold under the complex working condition, effectively prevent the scaffold from unstable conditions such as shaking, tilting and the like in the use process, provide a more stable working environment for the construction process and further improve the safety of a construction site.

3. Unlike some traditional methods, which require holes to be formed in the building structure, steel bars to be implanted, or a large number of auxiliary structures to be built, the technical scheme of the utility model reduces the damage and transformation to the main structure of the building to the greatest extent. This not only reduces construction difficulties and risks, but also avoids construction delays and additional cost increases due to large-scale modification of the building structure. Constructors can quickly complete the installation and debugging work of the attached lifting scaffold on the premise of not affecting the integrity and stability of the building structure, so that the construction process is smoother, and the overall construction efficiency is improved.

4. The integral attaching device of the attached lifting scaffold adopts a relatively simple supporting and hard pull rod structure, and the required materials are mainly common building materials such as steel materials and the like, so that the cost is relatively low. Compared with the traditional method that a large amount of special steel materials are required to be used for manufacturing auxiliary structures or special attaching supports, the material purchasing cost is greatly reduced. Moreover, the structure is simple, the utilization rate of the materials is higher, the material resources are further saved, the requirements on cost control and resource saving in modern building construction are met, and obvious economic benefits are brought to construction enterprises.

5. The integral attaching device of the attached lifting scaffold can realize effective adaptation to different structural changes by reasonably adjusting the position, angle, length and other parameters of the support and the hard pull rod no matter how complex and various the odd-even layer change forms of the building structure are. The utility model can flexibly treat the conditions of floor height difference, wall structure change, special beam column layout and the like, and ensures the safe attachment and normal use of the scaffold.
