First Floor House Lintel Beam Working Drawing with Reinforcement

 This AutoCAD DWG file contains a detailed first-floor house lintel beam working drawing with complete reinforcement specifications for residential construction. The layout clearly identifies lintel beam types TL1, TL2, TL3, and TL4 positioned above door and window openings, with standard beam sizes of 9 inches by 6 inches and 4 inches by 6 inches. Cross sections at midspan and support are provided, showing reinforcement arrangements such as 2 to 3 numbers of 10 millimeter bars, stirrup spacing, anchorage lengths, and clear cover requirements. The drawing also includes a landing beam sized 9 inches by 15 inches integrated with the staircase, along with a typical loft slab and lintel connection section. Structural notes specify concrete grade M20 and steel grade Fe500, ensuring clarity for execution. This first-floor house lintel beam working drawing is suitable for architects, civil engineers, and builders using AutoCAD for accurate residential structural detailing, with reference to mixed-use building drawings that integrate shops and living areas following similar structural detailing, reinforcement coordination, and execution-ready AutoCAD documentation standards.
