Lightning protection construction method for cantilever scaffold of high-rise building

Abstract

The invention discloses a lightning protection construction method for a cantilever scaffold of a high-rise building. In construction stage of a main structure of the high-rise building, the main structure of the high-rise building is designed into a structure that every other three floors are in equipotential connection through frame beam steel bars around the building to form internal grinding rings of the floors, and the internal grinding rings of the floors are connected with steel bars of cast-in-place piles of the high-rise building through in-column steel bar down leads; during construction of the internal grinding rings of the floors, the internal grinding rings of the floors are connected with vertical steel pipes of the cantilever scaffold through lightning protection leads. The lightning protection construction method for the cantilever scaffold of the high-rise building has the advantages that construction organization is facilitated, and connection with a body of the cantilever scaffold is completed during lightning protection construction of a body of the high-rise building, so that lightning protection is realized; technical simplicity and high operability are achieved, lighting protection of the body is made full use of to guarantee lightning protection effects, additional arrangement of grounding electrodes and down leads is avoided, and accordingly the cost is reduced to a great extent.

Description

technical field [0001] The invention belongs to the field of lightning protection and grounding, and in particular relates to a construction method for lightning protection and grounding of cantilevered scaffolding in high-rise buildings. Background technique [0002] For the lightning protection and grounding of traditional cantilevered scaffolding, it is necessary to separately lay down conductors and set grounding electrodes after the frame body is erected. The disadvantage of the traditional method is that it is difficult to achieve synchronous connection between the erection of scaffolding and lightning protection grounding, and laying alone is not conducive to organization. If the connection is not good, the probability of lightning strike accidents is high; Long lines consume a relatively large amount of resources, which is not conducive to cost control. [0003] In the construction phase of the main structure of a high-rise building, the main structure is designed...
