| Description | Kāshtha Chhata Dhancha (काष्ठ छत ढांचा), or timber roof framing, is a traditional Indic construction method employing wood for structural roof support. Predominantly utilizing hardwoods like teak (सागौन - Sagaun) and sal (साल - Sal) from forests across the Indian subcontinent, and softwoods like deodar (देवदार - Devadāra) from the Himalayan region. The material's biological origin dictates its properties: bending strength (40-100 MPa), density (500-800 kg/m³), and thermal conductivity (0.12-0.18 W/mK) [2]. Seasoning reduces moisture content (12-18%) improving durability. Historically, Rajput Dynasty and Maratha Empire architecture extensively used Kāshtha Chhata Dhancha. Traditional joinery techniques, including mortise and tenon, create robust structures. The structural elements include rafters, purlins, and wooden collars [1]. Conservation necessitates addressing decay from fungal attack and insect infestation. Restoration involves sourcing compatible timber and employing traditional carpentry skills. Daru Chata Sanrachana (दारु छत संरचना) is a Sanskrit term for this construction. Understanding material properties is crucial for preserving heritage sites [3]. |
