| Description | Lakadee Kee Chhat Tras (Timber Roof Truss), or काष्ठ छत ट्रस (Kāshtha Chhat Tras), represents a vital structural element in Indic heritage architecture. Traditionally constructed from timbers like teak (सागौन - Sāgaun) and sal (साल - Sāl), sourced from forests across the Indian subcontinent, these trusses exhibit a modulus of elasticity between 8-12 GPa and density ranging from 500-800 kg/m³. Bending strength typically falls between 50-100 MPa, with a moisture content of 12-18%. The chemical composition primarily consists of cellulose, hemicellulose, and lignin. Historical usage spans across dynasties, evident in structures from the Mauryan to Mughal periods. Traditional joinery techniques, often employing wooden collars [1], ensured structural integrity. Conservation efforts necessitate careful assessment of decay due to biological agents (fungi, insects) and moisture ingress. Restoration involves replacing deteriorated members with seasoned timber of comparable species and properties. दारु छत ट्रस (Dāru Chhat Tras) highlights the importance of wood (दारु - Dāru) in roofing. Understanding the material science of these trusses is crucial for preserving architectural heritage. |
