A king post is the vertical member of a simple truss which runs from the bottom chord of the truss to the high-point where the two top chord members meet. The king post dissects the single triangle of the truss and splits the truss into two smaller trusses usually of equal size / shape.
Lamella roof is a curved roof framed by a system of intersecting skewed arches made up of relatively short members called lamellas. Each short member intersects with another member of the opposite skewed arch as each member works to form one long arch.
Lamella roof construction was invented in Europe in 1908 and introduced in the United States in 1925. Since that time numerous buildings have been constructed with lamella roofs, however, due to failures, the use of lamella roofs has diminished since the 1970's.
Anyone that has been around the building industry knows there is a whole lingo that can be a little hard for the layperson to follow. Terms such as 'furring' and 'fire blocking' may make perfect sense to the architect or contractor but to the average person or someone new to the industry, their meanings are not so clear. Also, by assciating various terms with a building, one who is learning about the building / architecture, can better understand the term and it's use.
You can look up terms by typing the term in the box to the right or by browsing terms here.
