IMPROVEMENTS IN STRUCTURAL STEEL LINTELS

Abstract A structural lintel 10 is similarly shaped as an I-beam having a horizontal lower (or bottom) flange 12, a horizontal upper (or top) flange 13 and a vertical web 14 extending therebetween. The flanges 12 and 13 and the web 14 form spaces 19a and 19b, at respective 5 lateral sides of the web...

Zusammenfassung:Abstract A structural lintel 10 is similarly shaped as an I-beam having a horizontal lower (or bottom) flange 12, a horizontal upper (or top) flange 13 and a vertical web 14 extending therebetween. The flanges 12 and 13 and the web 14 form spaces 19a and 19b, at respective 5 lateral sides of the web 14. The upper flange 13 is narrower in width than the lower flange 12. The depth of the lintel 10 is determined by the height of the web 14. The height of the web 14 is chosen such that the internal depth, being the distance between the facing internal surfaces 12i and 13i of the lower flange 12 and the upper flange 13 is equal to: Number of brick courses (N) * Depth of each brick in mm (D)+ 0 (N-1) * Mortar Course Thickness in mm (M) Where N>2 13i X3i 14 -19a- -19b 12i 12i
