耐風圧設計用計算尺。[Claims for Utility Model Registration] A movable scale having first and second scales on both sides, and first and second scales disposed close to the first and second scales of the movable scale, respectively. In a slide rule having a fixed scale, the first and second fixed scales are composed of logarithmic scales arranged in opposite directions, and the first fixed scale measures the wind pressure P relative to the second fixed scale. respectively indicate the glass area A, while the first scale formed on both sides of the moving scale indicates the type of glass, the second scale indicates the thickness t of the glass, and the first scale formed on both sides of the moving scale indicates the glass type. The first scale is based on ordinary glass, the coefficient of each glass is a, and the length of 1 logarithm unit is S; it is graduated so that L=loga×S, and the second scale is; L'=log (t + (t 2 /4)), and the first scale and the second scale are; A = (30a/P) (t + (t 2 /4)). A slide rule for wind pressure design of glass characterized by being arranged as follows.
