Blonde Girl Undresses Her Black Panties On The Timber Roof Truss Framework With An Open Ceiling Area

The terms closed truss and open truss are used in two ways to describe characteristics of truss roofs. Closed truss: 1) A truss with a tie beam; 2) a roof system with a ceiling so the framing is not visible. Open truss: 1) A truss with an interrupted tie beam or scissor truss which allow a vaulted ceiling area; 2) Roof framing open to view, not hidden by a ceiling.
• King post truss
A king post truss has two principal rafters, a tie beam, and a central vertical king post. The simplest of trusses, it is commonly used in conjunction with two angled struts.
The king post is normally under tension, and requires quite sophisticated joints with the tie beam and principal rafters. In a variation known as a king bolt (rod) truss the king post is replaced by a metal bolt (rod), usually of wrought iron.
