External hanging scaffold and application method thereof

Abstract

The invention discloses an external hanging scaffold and an application method thereof. The scaffold is built at one time, is attached on a building, adopts a tower crane mounted on a building construction field as elevating power equipment, and comprises a vertical truss, an attaching device and a scaffold body, wherein the scaffold body is connected with the vertical truss which is connected with the attaching device; the attaching device is connected with the building; the attaching device comprises an anti-tilting rod piece positioned on the upper part of the vertical truss and a bearing outrigger positioned on the middle lower part of the vertical truss; and an automatic limiting device is arranged on the bearing outrigger. The application method of the external hanging scaffold comprises the steps of mounting, fixing, elevating and demounting. The external hanging scaffold disclosed by the invention has the advantages of simple structure, convenience for use and extremely good economic and social benefits.

Description

technical field [0001] The invention relates to a scaffold for building construction, in particular to a scaffold used for protection during the construction phase of a building main body. Background technique [0002] In the past, most of the exterior wall materials of domestic high-rise buildings used ceramic tiles. Recently, due to the frequent safety accidents of tiles falling off and causing injuries and damages, they were gradually replaced by paints. The best machine for paint application is a hanging basket. Therefore, in the construction stage of the exterior wall, the traditional scaffolding is also replaced by the hanging basket accordingly. But in the main construction stage, there was no dedicated scaffolding before. In the prior art, there is a kind of external scaffolding, which is set up in pieces along the building, once set up and formed, and attached to the building. When the building is raised by one floor, a tower crane is used as the lifting power to...

Problems solved by technology

However, since the building structure usually has a closed shear wall structure, if this structure uses wall-through screws, personnel must stand on the scaffold to remove the wall-through screws when the scaffold is lifted. If the scaffold falls at this time, a safety accident will occur, so There are major safety hazards; and cantilever members generally have a large cross-section because they need to meet the strength requirements. If openings are opened in the shear wall, the building structure will be weakened, and there are also disadvantages

In addition, there are usually protruding or concave structural changes on the facade of the building. When the scaffold is lifted, its anti-roll bar or the force-bearing member as the load-bearing fulcrum will collide or interfere with it accidentally, resulting in damage. Therefore, the operation of this kind of scaffolding is not very convenient, and the adaptability needs to be improved.
