Building lightning protection range determining method

Abstract

The invention provides a building lightning protection range determining method, comprising: determining ball radius of a lightning rod according to building lightning arrest level so as to determine a protection range for each lightning rod acting as an independent lightning rod; determining a surface independent protection range circle of each lightning rod and a building height level independent protection range circle of each lightning rod according to the protection range of each lightning rod acting as the independent lightning rod; determining a joint protection range envelope curves of all lightning rods around a building in the building height level; monitoring whether the current building lightning protection range is feasible or not according to whether the building height is within the joint protection range of any two lighting rods or not. Three-dimensional ball concept is simplified as two-dimensional planar drawing method, and drawing results are vivid, simple and clear.

Description

technical field [0001] The invention belongs to the technical field of lightning protection for buildings, and in particular relates to a method for determining the lightning protection range of buildings. Background technique [0002] Buildings on many hilltops and open areas are very likely to be attacked by lightning, and then cause building fire accidents. Therefore, accurately determining the protection range of lightning protection facilities for buildings is an important task to effectively verify whether the main buildings and equipment are within the effective protection range of lightning protection facilities. The traditional Appendix D of "Code for Design of Building Lightning Protection GB50057-2010" is the rolling ball method in Appendix IV of "Code for Design of Building Lightning Protection GB50057-2000", which involves many formulas, as well as many height and position symbols, and the calculation is cumbersome. . Although some scholars and technicians hav...

Problems solved by technology

These calculation programs are not easy to obtain for architectural design and construction technicians, and the accuracy of program calculations cannot be verified by relevant technical personnel who do not understand programming. The simple numerical results of the calculations do not have much guiding significance for relevant technical personnel

The algebraic calculation method provided by the traditional "Code for Lightning Protection Design of Buildings" is not intuitive enough for the description of the lightning protection range of the rolling ball method, which is originally a geometric problem.
