Manufacturing method of parapet wall groove aluminum coping serving as roof lightning protection belt

Abstract

Provided is a manufacturing method of a parapet wall groove aluminum coping serving as a roof lightning protection belt. The manufacturing method includes the steps that bolts connected with reinforcing steel bars in a parapet wall are pre-buried in the top of the parapet wall of a plant with the building height of 20 m or below, groove aluminum with the surface sprayed with fluorocarbon paint isfixed to the bolts pre-buried in the top of the parapet wall, and a closed loop is formed along the top of the roof parapet wall; and a copper-clad steel round wire is connected with the groove aluminum at the top of the parapet wall to serve as a lower lead to be exposed along an outer wall, and the lower lead of the copper-clad steel round wire is connected with a main grounding grid. The groovealuminum has excellent conductivity, and the groove aluminum sprayed with the fluorocarbon paint is good in corrosion resistance in the atmospheric environment containing chloride, low in price, goodin plasticity and convenient to machine; and parapet wall coping groove aluminum decorations with proper shapes and section sizes are selected as the lightning protection belts to replace lightning protection belts integrally adopting the copper-clad steel round wires, so that the problem of lightning protection belt installation space can be solved, the requirement for the consistency of the overall sense of a plant wall can be met, and the lightning protection belt has the advantages of being reasonable in structure, simple in method, resistant to corrosion, good in safety, low in cost andlong in service life.

Description

technical field [0001] The invention relates to the technical field of lightning protection for buildings, in particular to a method for manufacturing a parapet groove aluminum pressure top that doubles as a roof lightning protection belt. Background technique [0002] "Code for Lightning Protection Design of Buildings" (GB50057) clearly stipulates that in order to prevent or reduce personal casualties and property losses caused by lightning strikes on buildings, buildings should adopt lightning protection designs according to local conditions. At present, the external lightning protection devices in the lightning protection design of buildings, such as lightning protection belts, are installed on the roof parapet or the highest part of the roof; the lightning protection belt materials can be copper, tinned copper, aluminum, alloy aluminum, hot-dip galvanized steel , stainless steel and copper-plated steel and other metal conductors, among which the copper-plated round steel...

AI Technical Summary

Problems solved by technology

At present, the external lightning protection devices in the lightning protection design of buildings, such as lightning protection belts, are installed on the roof parapet or the highest part of the roof; the lightning protection belt materials can be copper, tinned copper, aluminum, alloy aluminum, hot-dip galvanized steel , stainless steel and copper-plated steel on the outer surface and other metallic conductors, among which the copper-plated round steel wire on the outer surface is mostly, the cost is high, and the installation space requirements are relatively high, so it cannot be used in some installation occasions with limited space
