Crossing
Crossing is a term used in the carpentry trade . It is used there for two different constructions which have the same purpose, namely the stiffening of the construction.
- Crossing at wooden beam ceilings . The lateral bracing of beams through the crosswise use of logs or slats in the spaces between a wooden beam ceiling ensures that traffic loads are evenly removed . In modern timber construction , narrow laminated beams or planks standing on the narrow side are often used instead of solid beams . Instead of bars under pressure, perforated straps (as pull ropes ) are often used for support , which are placed crosswise around the beams ( braided ) and nailed to them.
- Crossing in half-timbered structures . Struts between the wooden posts, e.g. B. in the form of a St. Andrew's cross , stiffen the framework construction. This principle is also used in modern timber construction in the form of tie rods or pull ropes.
- In the same way, the wind riser tape is used to stiffen roof structures .
