Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an attached lifting scaffold. Background Art

[0002] At present, the emergence and development of attached lifting scaffolding is mainly due to the demand for efficiency and safety in high-rise building construction. The technology of attached lifting scaffolding is gradually evolved on the basis of traditional scaffolding technology, combined with the development and innovation of modern construction technology. Traditional scaffolding technology has many shortcomings when facing the construction of high-rise and super-high-rise buildings, such as low construction efficiency, large labor demand, high safety hazards, etc. The emergence of attached lifting scaffolding has effectively solved these problems.

[0003] The authorization announcement number in the prior art is: CN107605142B, and the name is an attached lifting scaffolding structure, including a frame structure, a spatial truss structure base and a track assembly. The ingenious combination of these components makes the entire scaffolding system both stable and flexible. The frame structure, as the main part of the entire system, bears the main construction load, and a spatial truss structure base is fixed to its bottom, which not only enhances the stability of the frame, but also provides reliable support for the track assembly. The design of the track assembly is particularly ingenious, and its bottom is connected to the spatial truss structure base through a sliding sleeve, so that the track assembly can slide freely in one direction. This design not only facilitates the installation and disassembly of the scaffolding, but also enables the scaffolding to flexibly adapt to various construction environments during the lifting process. At the same time, the upper part of the track assembly is connected to the frame structure through a triangular support assembly, which further enhances the stability and safety of the entire system. This attached lifting scaffolding also reduces abnormal friction caused by installation deviation by simplifying the structure. Traditional scaffolding systems are often prone to deviations due to their complex structure and cumbersome installation, resulting in increased friction and resistance during the lifting process. This new type of scaffolding optimizes the structural design to make the installation process simpler and faster, while also reducing the friction problem caused by installation deviations. However, although the installation and disassembly of this patent are relatively simple, the structure is relatively complex and it takes a lot of time to assemble, resulting in low work efficiency. In addition, there is no protection for workers during the lifting process, and the protection is poor.

[0004] The authorization announcement number in the prior art is: CN209082958U, and the name is an attached lifting scaffold, which is composed of a supporting base, a hydraulic telescopic rod, a connecting rod, a screw, a slide rail and a plug rod. The components are tightly matched. The slide rail is vertically fixed on the building wall, and the plug holes are arranged at equal intervals on it, which provides a stable track and fixed points for the lifting of the scaffold. The supporting base is firmly installed on the slide rail through the plug rod to ensure the stability of the entire scaffolding system. The hydraulic telescopic rod is vertically installed on the slide rail, and the length can be adjusted according to the construction needs to realize the lifting function of the scaffold. Yes, a number of connecting rods are installed on the hydraulic telescopic rod, and these connecting rods are connected by screws. The width and height of the scaffolding can be flexibly adjusted to meet the needs of different construction environments. Grooves compatible with the slide rails are designed at both ends of the connecting rod, and second fixing holes corresponding to the sockets are opened at both ends of the grooves, so that the connecting rod can be firmly installed on the slide rail. However, this patent pushes the entire connecting rod upward through the hydraulic rod at the bottom, but one end of the connecting rod is inside the slide rail, which makes the connecting rod tilted when it is upward, the lifting distance is limited, and the adjustment is more troublesome. Moreover, each connecting rod is directly connected, which makes the installation more troublesome. Utility Model Content
