Building roofing stainless steel rail lightning protection construction method based on attached type support

Abstract

The invention discloses a building roofing stainless steel rail lightning protection construction method based on attached type supports; the method comprises the following steps: lightning strip support installation: mounting a plurality of lightning strip supports outside the upper portion of the stainless steel rail on the building roofing, wherein the lightning strip support is an attached type support, each attached type support is fixed outside the upper portion of each rail vertical rod; the attached type support is a J-shaped support, and comprises an outer connecting rod, an inner connecting rod and an arc-shaped connecting section, wherein the inner connecting rod is fixed on the rail vertical rod through a plurality of support connectors; 2, lightning strip installation: using the outer connecting rods of the lightning strip supports to support the lightning strip; 3, downlead connection: welding and fixing the top of the lightning protection downlead with the lightning strip. The building roofing stainless steel rail lightning protection construction method is simple in steps, reasonable in design, good in usage effect, can simply and fast finish the building roofing stainless steel rail lightning protection construction process, and can provide good conductive performance on the construction moulding lightning protection units.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a lightning protection construction method for stainless steel railings on building roofs based on an attached bracket. Background technique [0002] A complete set of lightning protection devices includes lightning receptors, down conductors and grounding devices. Among them, the lightning receptor is the part used to receive the lightning current, which is in the form of metal components such as lightning rods, lightning protection nets, and lightning protection belts; the down conductor refers to the metal conductor connecting the lightning receptor and the grounding device, also known as lightning protection. line or lightning protection down conductor. The down conductor of the lightning protection device should meet the requirements of mechanical strength, corrosion resistance and thermal stability. At present, when carrying out lightning protect...

AI Technical Summary

Problems solved by technology

At present, when carrying out lightning protection construction on stainless steel railings in the construction process, it is usually used to directly overlap and weld the down conductor and the stainless steel railing. The above-mentioned traditional method mainly has the following defects: First, the down conductor and the stainless steel When the railings are connected, due to the arc-shaped section and wall thickness of the stainless steel railings, the welding quality of the connection between the down conductor and the stainless steel railings in the vertical and horizontal directions is difficult to meet the requirements, which directly affects the construction of the lightning protection device. The overall conductivity; second, since the air receptor and down conductor are usually made of carbon steel, when welding with stainless steel railings, the welding quality between stainless steel and carbon steel is difficult to meet the quality requirements, and deformation, needles, etc. often occur Holes, scratches, cracks, undercuts and other defects have stricter technical requirements for workers; third, argon arc welding is usually used in the welding process, and argon arc welding is more harmful to the human body. Higher levels of ozone
