Die vorliegende Erfindung betrifft einenThe present invention relates to a

. Holzmast, der hauptsächlich für die Zwecke der drahtlosen Telegraphie usw. Verwendung finden soll. Bei derartigen Holzmasten,. Wooden pole mainly used for the purpose of wireless telegraphy etc. should find. With such wooden masts,

die im Interesse der Überbrückung großer Entfernungen verhältnismäßig hoch und stark gebaut sein müssen, um das hierbei notwendige, eine große Windfläche bietende umfangreiche Netz halten zu können, besteht der Wunsch,those in the interest of bridging great distances are relatively high and strong must be built in order to accommodate the extensive wind area required for this To be able to hold the net, there is a desire

ίο neben leichter Transportfähigkeit auch die Errichtung des Mastes möglichst einfach zu gestalten. Gewöhnlich werden die Masten aus einzelnen Stücken des erforderlichen Durchmessers hergestellt, indem man dieselben stehend übereinander anordnete und befestigte, jedoch ergab sich hierbei der Umstand, daßίο In addition to easy transportability, also the Erecting the mast as easy as possible. Usually the masts made from individual pieces of the required diameter by cutting the same arranged and fastened standing one above the other, but this resulted in the fact that

. infolge der überaus schwierigen Errichtung des Mastes die Verbindungsstelle zwischen den Einzelteilen verhältnismäßig klein gehalten werden mußte und häufig ungenügend war. Jedenfalls wurde hierbei die Errichtung besonders hoher und starker Masten unmöglich gemacht. Man hat daher auch versucht, die einzelnen Teile liegend am Erdboden miteinander zu verbinden und den Mast darin seiner ganzen Länge nach hochzurichten. Dann sind aber besondere umfangreiche Gerüste zum Aufrichten notwendig, die die Herstellung und Aufstellung solcher HoIzmasten erheblich komplizieren und verteuern, die. es aber gleichfalls unmöglich machen, über eine gewisse Länge hinauszugehen,- weil sonst die Schwierigkeiten bei der Errichtung so groß werden, daß man Heber zu den wesentlich teueren Eisenmasten übergeht.. due to the extremely difficult erection of the mast, the junction between the items had to be kept relatively small and often insufficient was. In any case, the erection of particularly tall and strong masts became impossible made. Attempts have therefore also been made to lay the individual parts together on the ground to connect and raise the mast along its entire length. Then, however, special extensive scaffolding is necessary for erecting, which the manufacture and erection of such wooden masts considerably complicate and make the. but also make it impossible to go beyond a certain length - because otherwise the difficulties in erection get so big that jacks are passed over to the much more expensive iron masts.

Die vorliegende Erfindung will bei Holzmasten die beschriebenen Nachteile dadurch vermeiden, daß ein Mast verhältnismäßig großen Querschnittes ohne besonders stark geschwächte Punkte aus einer großen Anzahl verhältnismäßig kurzer und schwacher Einzelteile zusammengesetzt wird, die, zu mehreren vereinigt, die notwendige Stärke des Mastes ergeben. Dabei werden diese.Einzelteile so zueinander versetzt angeordnet, daß an einer Verbindungssteile für einen bestimmten Einzelteil stets eine größere Anzahl von durchgehenden Balken für die notwendige Festigkeit sorgt. Gleichzeitig bietet sich hierdurch jederzeit die Möglichkeit, von dem am meisten vorspringenden Ende des Mastes mittels Seilaufzuges einen neuen Einzelteil emporzuheben, ihn zu befestigten und ihn seinerseits wieder zum Hochziehen weiterer Einzelteile zu benutzen.The present invention aims at the disadvantages described in wooden poles avoid having a mast of relatively large cross-section without being particularly strong weakened points from a large number of relatively short and weak individual parts is put together, which, united to several, the necessary strength of the mast result. These individual parts are offset from one another in such a way that connecting parts are connected to one another a larger number of continuous beams always provides the necessary strength for a certain individual part. At the same time, this offers the possibility of the most protruding one at any time At the end of the mast to lift a new item by means of a cable hoist, to close it and to use it in turn to pull up further items.

Die Erfindung ist auf der beiliegenden Zeichnung zur Veranschaulichung gekommen, und zwar ist:The invention has come to the illustration on the accompanying drawing, namely is:

Fig. ι eine perspektivische Ansicht eines teilweise errichteten Mastes undFig. Ι a perspective view of a partially erected mast and

Fig. 2 ein Querschnitt durch den Mast in Höhe der Abfangseile.Fig. 2 is a cross section through the mast at the level of the interception ropes.

Wie schon erwähnt, besteht der Mast vorliegender Erfindung nicht, wie bisher, aus einzelnen Mastteilen, die gleich die notwendige Stärke des Mastes besitzen und die, einfach aneinander gereiht, den Mast ergeben, sondern der Mast vorliegender Erfindung besteht aus verhältnismäßig kurzen und schwachen Einzelteilen I, 2, 3, 4, die, nebeneinander gestellt, die notwendige Stärke des Mastes ergeben. In der Zeichnung ist angenommen, daß der Mast einen viereckigen Querschnitt besitztAs already mentioned, the mast of the present invention does not, as before, consist of individual mast parts, which have the necessary strength of the mast and which, simply lined up in a row, result in the mast, but the mast of the present invention consists of relatively short and weak individual parts I, 2, 3, 4, which, placed side by side, result in the necessary strength of the mast. In the drawing it is assumed that the Mast has a square cross-section

Claims

and is formed from four individual parts i, 2, 3, 4 in cross section. Of course, there is also the possibility of forming any other cross-section of the mast from any number of individual parts. With regard to this arrangement of the mast parts next to each other, the items can be relatively weak, so that they are easily transportable. The parts ίο are fastened to one another by means of screw bolts 5 or in another appropriate manner. In addition to the advantage of easy transportability of the individual mast parts, this mast construction has the main advantage that the 15 'mast can be erected easily and without difficulty up to relatively great heights, and this is done in the following way: On a cement block 6, which is expediently with a Base plate 7 is provided, the foundation pillars 8, 9, 10, 11 are first arranged in such a way that a mast with a square cross-section is created by juxtaposing the individual parts. As shown in FIG. 1, these basic parts end at different heights and are secured to one another in the manner shown in FIG. 2 by screw bolts 5 or otherwise. A roller is now attached to the protruding end of the highest base part 11 and a new item 12 is pulled up by means of a rope over it, which is placed on the lowest base part 8 and fastened to the other parts by screw bolts. The length of this newly added part 12 is such that it protrudes beyond the longest base part 11 after being placed on the base part 8. Now a pulley 13 is attached to this most protruding end of the part 12 in a similar manner and another part 14 is lifted by means of a rope, the. is placed on the end of the base part 9. This new part 14 * can have the same length as part 12 and must, since the pillars 8 and 9 have different lengths, protrude further than the previously set up part 12. After fastening to the other parts by means of screw bolts, at the protruding end of this part 14 again attached the pulley and another part 15 lifted, attached to the other side parts, etc. In this way, part by part can be lifted and placed on the mast. It is therefore easily possible to bring the mast directly to the desired height by layering individual parts on top of one another. Since the beams are relatively light, there are no difficulties in pulling them up or fixing them in the higher parts of the mast. Of course, it is just as easy to dismantle the mast. As is known, this mast is to be secured at a suitable height by means of arresting ropes 16. For this purpose, metal straps 17 are used, which are connected to the corners of the mast by screw bolts 18 and pressed against the mast, but at the same time also serve to fasten the ends of the interceptors. With masts designed in this way, towers can of course also be produced, which offers a special advantage in that the connecting struts that unite the individual masts do not, as was otherwise necessary, cause a certain weakening of the masts at the connection points, but by interposing them between the joint surfaces of the Individual parts that simply fit into the mast construction without any part of it being weakened or excessively stressed.
