Joist

When floor joists and the supporting structure of a ceiling or a floor is called when it is executed as a wood -beamed ceiling. When laying the joist is in the planning dimension to note about wood that needs to be adjusted to the base. The beam position is usually oriented in a direction that can change in multi-storey buildings to burden the load-bearing exterior walls evenly. In special situations, such as in corner houses, the bars can be oriented differently. The distances of each bar should be as equal as possible. In practice this is not always possible because the floor plan purports wall beams and recesses for fireplaces and stairs should be built as possible without change. The transverse beams are connected in multi-storey houses in regular intervals along the outer walls and by means of metal parts in order to stabilize the wall. These pins mentioned parts are often visible on the outer sides. A stiffening of the beam position is determined using wooden floor or on diagonally opposite metal bands reached ( Abkreuzung ).

Names of the timbers in the floor joists

Ortbalken

The Ortbalken, also called gable beams, located on an outside wall or gable. This bar, and two or three more, are now mostly anchored with metal braces in the wall, which are perpendicular to the joists.

Wall Construction

A wall bar located in an interior partition wall that this must be quite narrow, so that the boards can not lie. Wall beams are typical in internal truss. In exterior walls are to no bars, but have a few cm distance so as not to get wet. They underline the wall and therefore are also called spreader bar.

Space bar

The empty bar is a bar that is without interruption and without connection to other woods in the joists. It is also called full bar.

Change

The change in the location bar has the same function as the change in the attic. If the joists a recess necessary that cuts through a beam, then change are used which carry the loose end of the severed bar. The change at right angles to the joists and is secured to the next by passing beam, or is located on a supporting wall on.

A trimmer

The term change bar is used inconsistently. On the one hand, the term refers to a solid bar full length, joins onto an exchange. In some sources, however, the bill itself is referred to as a removable bar.

Stitch bar

A stitch bar is a bar with a shorter length, for example, on one end rests on a removable, and is used when the amount is too large wooden or opening interrupts the beams. The bite bar stabs on the exchange. Stitch bars are also used when projecting parts such as balconies or bay windows are fitted to one side parallel to the joists.

Wall stitch bar

Is the same as the needle bar in about, only that it rests against a wall or gable.

Corner stitch

The corner stitch, also called Gratstichbalken, protrudes between the last beams of the floor joists and the last thrusting it random bar at the outer corner. The corner stitch is needed mainly for hipped roofs, if a joist is present. The corner stitch runs under the hip rafters. At the same sloping roof sides of the corner stitch runs at a 45 ° angle to the Rähm. In different steeply sloped roof sides of the corner stitch runs at the correct angle for Rähm.
