Attached lifting scaffolding, commonly known as external climbing frame on construction sites. It mainly refers to the external scaffolding that is erected at a certain height and attached to the engineering structure, relying on its own lifting equipment and devices, and can climb or descend layer by layer with the engineering structure, with anti overturning and anti falling devices..
This new type of scaffolding is suitable for high-rise building construction, especially for super high-rise buildings. It has developed on the basis of hanging, hoisting, and hanging scaffolding..
Breaking the design concept and structural form of traditional lifting frames, replacing the traditional scaffolding method of using steel pipes and fasteners for installation,.
Replacing traditional wooden and bamboo scaffold boards with shaped steel walkway boards has comprehensively improved the safety, reliability, sealing, and aesthetics of the entire frame!.
In line with the national requirements for safety, energy conservation, low-carbon environmental protection, and green construction, it effectively solves the safety management problems of high-rise external protection operations that government regulatory departments and building general contracting units are concerned about, and completely avoids the risks and accidents of high-altitude and suspended operations of scaffolding..
The frame structure should adopt a coupler type steel pipe scaffold, and its structural structure should comply with the provisions of the Safety Technical Specification for Coupler type Steel Pipe Scaffolding in Construction (JGJ130-2011). The frame should be set between two vertical main frames and connected to them by longitudinal horizontal bars. The vertical bars should be set at the points where the horizontal support is sparse. The erection of the frame should also meet the following requirements.
3. The support span of the frame arranged in a straight line should not exceed 8m; The support span of the frame arranged in a broken line or curve should not exceed 5.4m;.
4. The overhanging length of the integral attached lifting scaffold frame shall not exceed 1/2 of the horizontal support span and 3m; The overhanging length of the single piece attached lifting scaffold frame should not exceed 1/4 of the horizontal support span;.
5. Under lifting and usage conditions, the cantilever height of the frame should not exceed 6.0m and 2/5 of the frame height..
6. The product of the total height of the frame and the supporting span should not exceed 110m ²。.
1. The frame must be equipped with a fixed and reinforced vertical main frame along the full height of the attached support area. The vertical main frame should adopt a welded or bolted sheet or lattice structure, and can function as a whole with the horizontal beam frame and frame structure. Steel pipe fasteners or bowl buckle frames and other scaffold members should not be used for assembly. The guiding structure between the vertical main frame and the attached support structure shall not be connected by steel pipe fasteners, bowl buckles, or other ordinary scaffolding methods;.
2. The horizontal beam frame of the frame should meet the requirements of bearing capacity and overall interaction with other frames, and adopt a fixed truss beam structure connected by welding or bolts; When the fixed truss components cannot be continuously installed, scaffolding members can be used locally for connection, but their length cannot exceed 2m, and reinforcement measures must be taken to ensure that their connection stiffness and strength are not lower than that of truss beam structures. In the nodes of the main frame and horizontal beam frame, the axes of each member should converge at a point;.
3. The exterior facade of the scaffold must be equipped with diagonal braces along the full height, and the span of the diagonal braces shall not exceed 6.0m; The horizontal angle is between 45 ° and 60 °, and the vertical main frame, the horizontal beam frame, and the frame should be connected as a whole;.
4. The cantilever end should be symmetrically inclined in pairs with the vertical main frame as the center.
