Description: Standing as distinctive symbols of Chinese architectural culture, timber-framed structures are found throughout the country. The wooden components such as the columns, beams, purlins, lintel and bracket sets are connected by tenon joints in a flexible, earthquake-resistant way. The surprisingly strong frames can be installed quickly at the building site by assembling components manufactured in advanced.
