Description

Hölzerner Bast. Die Erfindung bezieht sich auf hölzerne Maste, welche aus vier Eckpfosten und diese verbindenden, leitersprossenartig angeordneten Querbrettern bestehen: Der neue Mast soll besonders zur Aufnahme von Drahtleitungen und Antennen dienen, wobei in der Regel keine erhebliche senkrecht wirkende Last, dagegen aber seitliche Beanspruchungen durch Drahtzug und Winddruck aufzunehmen sind. Um derartige Maste mit tunlichst geringem Baustoffaufwand widerstandsfähig herzustellen, werden erfindungsgemäß die Querbretter von innen an dein Eckpfosten Reckmäßig durch Vernageln befestigt, wobei die Querbretter der aufeinanderfolgenden Scharen an ihren Enden mit Ausschnitten versehen werden, so daß sie beim Aufeinanderlegen mit Absätzen ineinandergreifen.Wooden bast. The invention relates to wooden masts which of four corner posts and cross boards that connect them and are arranged like a ladder rungs exist: The new mast is intended to accommodate wire lines and antennas serve, whereby as a rule no significant perpendicular load, but on the other hand Lateral loads from wire tension and wind pressure must be absorbed. To such Manufacture of sturdy masts with as little building material as possible will be according to the invention, the transverse boards from the inside to your corner post by nailing them horizontally attached, with the transverse boards of the successive flocks at their ends be provided with cutouts so that they are with heels when placed on top of each other interlock.

Auf der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

Abb. i zeigt einen Längsschnitt, Abb. 2 einen Querschnitt nach A-B der Abb. i.Fig. I shows a longitudinal section, Fig. 2 a cross section according to A-B of fig. i.

Der Mast besteht aus den vier Eckpfosten a und aus den, Querbrettern b1 und b2, welche innerhalb der Eckpfosten an diese angenagelt sind. Die in den beiden versetzten Lagen immer aufeinandergelegten Bretter sind an den Enden mit Ausschnitten cl und e2 von solcher festalt versehen, daß die aufeinanderfolgenden Bretter- benachbarter Scharen mit den Ausschnitten in der aus Abb. i ersichtlichen Weise übereinandergreifen. Dabei ist x die Breite eines Brettes, y dagegen die Breite oder Höhe des zwischen zwei unter sich gleich hohen Brettern b1 entstehenden Abstandes. -Tritt bei dem Mast eine seitliche Beanspruchung durch Winddruck auf, so werden hierdurch die Verbindungsnägel zwischen den Brettern und, denn Eckpfosten beansprucht, die Nägel haben aber nicht die volle Beanspruchung aufzunehmen, sondern der beispielsweise in der Zeichnungsebene von links nach rechts auftretende Druck schiebt jedes Brett b1 gegen das rechts liegende Querbrett b2 an; der Druck wird also durch das Querbrett b2 zum größten Teil auf die Pfosten a übertragen. Hierdurch wird es möglich, die ieitersprossenartige Verbindung für verhältnismäßig stark beanspruchte Maste anzuwenden, und zwar mit einfacher Nagelverbindung zwischen den Teilen.The mast consists of the four corner posts a and the cross boards b1 and b2 which are nailed to the corner posts inside the corner posts. The ones in the two staggered layers of boards that are always stacked on top of each other are at the ends with Excerpts cl and e2 of such festalt provided that the successive Boards of neighboring groups with the cutouts in Fig. I Way to overlap. Where x is the width of a board, y is the width or the height of the distance between two boards b1 of the same height. -If the mast is subjected to a lateral load due to wind pressure, it will be as a result, the connecting nails between the boards and, because corner posts are stressed, However, the nails do not have to take the full load, but for example Pressure occurring from left to right in the plane of the drawing pushes every board b1 against the cross board b2 on the right; the pressure is therefore through the cross board b2 largely transferred to the post a. This makes it possible to use the to use the ladder-like connection for relatively heavily used masts, with a simple nail connection between the parts.

Unerheblich ist es, ob der Mast von unten nach oben sich verjüngt, oder ob er gleichbleibenden Querschnitt erhält.It is irrelevant whether the mast is from below up tapers, or whether it has a constant cross-section.
