Gluelam
Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensioned lumber, dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis. In North America, the material providing the laminations is termed ''laminating stock'' or ''lamstock''. History The principles of glulam construction are believed to date back to the 1860s, in the assembly room of King Edward VI School, Southampton, King Edward VI College, a school in Southampton, England. The first patent however emerged in 1901 when Otto Karl Freidrich Hetzer, a carpenter from Weimar, Germany, patented this method of construction. Approved in Switzerland, Hetzer’s patent explored creating a straight beam out of several laminations glued together. In 1906 he received a patent in Germany for curved sections of glulam. Other countries in Europe soon began approv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
