Overhanging type outer scaffold and construction method

Abstract

The invention provides an overhanging type outer scaffold which comprises an outer scaffold body, the outer scaffold body is fixed to the outer side of a building outer wall through wall connecting pieces, and the wall connecting pieces comprise a first wall connecting piece, a second wall connecting piece and a third wall connecting piece. Compared with a traditional overhanging scaffold construction technology, the construction method has the advantages that by means of the construction method of embedded connecting steel plates on beams and fixing I-shaped steel, the problems that the overhanging scaffold has large requirements for I-shaped steel materials, and an embedded wall connecting rod is difficult to control on the aspect of parallelism and construction hole residues are solved.The embedded connecting steel plates do not affect masonry construction, the hidden danger of leakage caused by the fact that holes are reserved during masonry and the potential safety hazard causedby the fact that wall connecting rods are dismantled during worker construction are reduced, and the influence on the building structure is small. An overlong I-shaped steel material does not need tobe arranged to be fixed in a building, materials are saved, and the construction cost is saved. The problem that the parallelism of the embedded wall connecting rods is difficult to control is avoided, the construction efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a cantilevered external scaffold and a construction method. Background technique [0002] In the field of construction engineering, in order to facilitate the construction of workers and ensure the safety of workers, scaffolding is usually set up around the building. In the field of high-rise buildings, cantilevered external scaffolding is set up. At present, cantilevered external scaffolding has been widely used. Usually, the riveting ring is pre-embedded in the cantilever layer, and then the I-beam is installed. Set up scaffolding on the I-beam at one end of the extension. In order to make the outer scaffold stable, the outer scaffold should be reliably connected with the main structure. As for the connection method, the existing method is to pre-embed steel pipe fasteners, usually steel sleeves, when the superstructure is poured with concrete. The steel sleeves...
