Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zum Errichten eines Rohrturmbauwerks, insbesondere eines Unterbauturmes für bestehende Windenergieturmkonstruktionen, wobei aus Stahlplatten im Querschnitt im Wesentlichen ringsegmentförmige Schalen geformt werden, wobei die Formung der ringsegmentförmigen Wölbung der Schalen durch eine Mehrzahl von Abkantungen entlang des Umfangs derart erfolgt, dass eine Vielzahl von in Umfangsrichtung aufeinanderfolgenden, zueinander gewinkelten Flächen gebildet werden, wobei von den Schalen entlang geplanter axialer Verbindungslinien ein axialer Flansch radial nach innen oder nach außen von der Schale abgekantet wird, wobei zur Errichtung des Turmbauwerks die Schalen mittels der Flansche benachbarter Schalen aneinander angeordnet werden und durch die Flansche aneinander liegender Schalen zu einem Rohrsegment verbunden werden, wobei zur Verbindung eines Rohrsegments mit einem Fundament oder einem weiteren Rohrsegment oder einem weiteren Rohrturm im Rohrsegmentfußbereich und/oder im Rohrsegmentkopfbereich die Schalen an horizontalen Stirnkanten je einen horizontalen Flansch besitzen, sowie ein Rohrturmbauwerk und eine Türanordnung.
Abstract:
The invention relates to a method for making openings necessary for allowing installation devices in a post having a thin casing without running the risk of causing ruptures. The invention includes forming an elongated opening, at each end defined by an edge shaped like an arch of a circle or otherwise gently curves edge and elongated sides having inwardly bent edges.
Abstract:
A fixing device for antennas (6) comprises a support (1) which is anchored in an anchoring part. Said support (1) is configured in the form of a hollow body in whose cavity support parts (5) can be moved along guideways (4), the antennae (6) being fixed to these support parts. This enables the antennas to be moved from an easily accessible assembly position (8) into a working position (7) and vice versa. This simplifies the construction and maintenance of antennas of this type considerably.
Abstract:
The invention relates to a tower or a tower segment of a wind turbine, having a door for entering the inside of the tower, comprising a door frame, which has a door opening that is preferably closed by a door leaf. The invention further relates to a door frame for a door of a tower of a wind turbine, said frame having a door opening that is preferably closed by a door leaf, and to a wind turbine having a tower, a door provided for entering the inside of the tower, and a staircase leading to the door on the outside of the tower, preferably of a tower described above. The underlying object of the invention is to provide an air passage opening in at least one advantageous location. This object is achieved according to the invention in that the door frame has at least one air passage opening, particularly an air inlet opening.
Abstract:
The present invention aims to provide a hollow antenna tower structure for use in a wireless communications network. The tower comprises tubular tower sections made of concrete, and having a generally hollowed cross section. A movable base station unit, having at least one antenna and at least one micro wave link, is being disposed inside the tubular tower. The whole base station unit is movable up and down inside the tower by the aid of an elevator system. The tower further comprises at least one entrance into the tower and a climbing facility and/or a second elevator system, inside the tower, giving access to the base station unit.
Abstract:
Light tower provided with base radio station for mobile telephony comprising a transmission and power supply unit (14), situated in a housing compartment (2) of the shaft (1) of the tower, and a system of antennas (15), protected externally by case (20), antennas which are fastened on the shaft (1) in its summit portion below a head (4) covered by a dome (5) and provided with illuminating bodies (7), the transmission and power supply unit (14) being connected to the antenna system (15) by means of data transmission cables (16) positioned within the shaft (1).
Abstract:
A reinforcement assembly for use in the hand access hole of a tubular shaft is disclosed. In one embodiment, the assembly comprises a pair of units (11) placed opposing each other with one being inside the shaft and the other being outside the shaft. Each unit (11) has a plurality of tenons (13, 16) that mate with open spaces (18) of the opposing unit (11), and each has a flange (62) surrounding the tenons (13, 16) that contact the shaft in the area immediately surrounding the hand hole. The two units (11) are attached to each other and to the shaft by bolts or other suitable fastening devices. In another embodiment of this invention, the pair of units are positioned one inside the other with at least one mating mortise and tenon union for securely linking the units. A typical application of the assembly is reinforcement of the area surrounding the hand hole of a utility pole.
Abstract:
Poste de iluminação com compartimento interno encaixado em sua base para equipamentos de telecomunicação (1) onde todos os equipamentos podem ser instalados no interior da estrutura metálica do poste, em prateieiras e divisórias apropriadas (2), sendo que essas prateleiras são feitas em tela expandida para facilitar a ventilação e resfriamento dos equipamentos e a estrutura é fabricada em aço de alta resistência e galvanizado a quente, resistente às intempéries climáticas, com redução de espaço territorial para sua instalação, pois não possui gabinetes e equipamentos em torno de sua estrutura (3).
