Description

  The present invention relates to towers, and in particular to telecommunications towers used in telecommunications networks. More specifically, the present invention relates to a telecommunication tower segment, a telecommunication tower section, a telecommunication tower, a method for manufacturing a telecommunication tower segment, and a method for constructing a telecommunication tower.

  A popular technique for telecommunications towers / masts is a grid-like steel structure, whether the tower / mast is self-supporting or with branch lines. These masts are often galvanized and the steel structure is covered with a zinc layer. Steel towers are usually manufactured with a design life of 30-50 years. The coated structure is vulnerable to mechanical wear, and the grid tower is no exception. Since the tower is damaged on the surface during transportation and installation, such damage needs to be repaired during installation of the tower. Since there is no option of hot dipping at the time of tower installation, room temperature galvanizing or spraying is used as one method. Damage to the protective zinc layer is unavoidable during transportation and installation, and corrosion begins in the damaged area. Corrosion determines the design life of any steel structure, and some maintenance is required to stop corrosion during the life of the structure, with or without zinc coating.

  WO200008136717 discloses an elongated antenna tower structure including a base segment, an intermediate segment, and a termination segment (S1-S4). These segments are made of reinforced concrete and are interconnected longitudinally by a plurality of elongated fastening members that together form a longitudinal interconnect structure that interconnects the base segment to the terminating segment without creating a longitudinal gap. The Each segment includes a plurality of fastening member guides formed on the wall of the segment and arranged to hold the fastening member in a predetermined configuration relative to the segment. See FIG. 1, FIG. 2, and FIG.

  WO 2007108766 and WO 2007108765 disclose a conical hollow antenna tower structure with a vertical elongated tower body having an internal mounting axis. The tower is configured to accommodate a radio base station, and the tower body includes two or more modular segments with mating interconnection mechanisms including a plurality of mating guide structures.

  WO 2007108731 discloses a radio base station, a tubular tower section having a hollow cross section, a configuration for moving the entire antenna radio base station along a longitudinal section of the antenna tower structure, and an arrangement inside the tubular tower. Disclosed is an antenna tower structure comprising an installed antenna radio base station and an entrance into the antenna tower structure that allows access for repair of the antenna radio base station.

  The inventor has noted that the quadrants used for the above-ground sections in previous tower structures can cause some manufacturing problems. First of all, these quadrants may be too large for transport on public roads. This is because these quadrants are not stacked and require special permission to move. Furthermore, due to the shape of the quadrants used so far, these need to be molded in a double-sided mold. Furthermore, molding with a double-sided mold may take time, which in turn can be expensive. The combination of the existing quadrant shape and the concrete maximum compressive strength requirement of 90 MPa usually makes it extremely difficult to produce large-scale ground sections in a quick and inexpensive manner. Even if it can be manufactured, the components and dimensions used so far (cement ratio, superplasticizer, etc.) result in an expensive structure.

  It is an object to provide an improved telecommunications tower segment while avoiding one or more of the above disadvantages or defects, alone or in combination.

  According to a first aspect of the invention, a telecommunications tower segment is provided for configuring a section of a telecommunications tower. The telecommunication tower may have a plurality of solid walls. A telecommunications tower segment can be attached to another telecommunications tower segment so that a plurality of such telecommunications tower segments can be used to form a tubular section of the telecommunications tower. Furthermore, the telecommunication tower segment has a convex first surface. The telecommunications tower segment further has a second surface opposite the first surface, the second surface being flat or partially flat.

  The telecommunication tower segment has a first end and a second end, the first surface and the second surface extending from the first end to the second end, the first end Looking towards the second end, the telecommunications tower segment has a gradually increasing outer periphery.

  Since the sections can be formed by arranging several telecommunications tower segments, these segments can describe one common frustoconical outer surface.

  The second surface can comprise one or more open recesses.

  The telecommunications tower segment may comprise one or more tubes or tubular cavities extending from the first end to the second end.

  The telecommunications tower segment can have at least one side with a groove suitable for connecting the telecommunications tower segment to another telecommunications tower segment so that a section of the telecommunications tower can be configured.

  The telecommunications tower segment may be connected to other telecommunications tower segments by injection.

  The length of the telecommunications tower segment can be approximately 9 meters and the width of the widest end can be approximately 2 meters. Alternatively, the length of the telecommunications tower segment can be approximately 5 meters and the width of the widest end can be approximately 2 meters.

  The telecommunications tower segment is preferably made of reinforced concrete, but this is not necessarily so.

  The telecommunications tower section may include a plurality of telecommunications tower segments.

  The cross section of the telecommunications tower section may form a perimeter circle.

  The telecommunications tower section may include eight telecommunications tower segments as described above.

  The telecommunications tower section may form the base section of the telecommunications tower or the ground section.

  According to a second aspect of the invention, the telecommunication tower comprises a plurality of telecommunication tower segments forming a telecommunication tower section of the telecommunication tower. Each telecommunications tower segment has a convex first surface, and each telecommunications tower segment further has a second surface opposite the first surface. The second surface is flat or partially flat. The shape of the second surface can be formed as a result of molding the segment in an open mold.

  According to a third aspect of the present invention, there is provided a method of manufacturing a telecommunications tower segment for constructing a telecommunications tower section of a telecommunications tower. The telecommunications tower segment is molded in an open mold.

  According to a fourth aspect of the present invention, a method for constructing a telecommunications tower is provided. The method includes assembling a plurality of telecommunications tower segments to form a telecommunications tower section and using the telecommunications tower section as a telecommunications tower section.

  According to some embodiments, the telecommunication tower is hollow or tubular.

The molded antenna tower structure is shown. The antenna tower is shown. The section division of the tower base is shown. Figure 2 shows a cross-sectional view of an embodiment of the tower section. Fig. 5 shows an embodiment of segment molding from an angle. Fig. 4 shows an embodiment of segment molding from another angle. Fig. 4 shows an embodiment of segment molding from another angle.

  To avoid one or more of the drawbacks of conventional solutions, particularly the above solutions, a telecommunications tower segment is provided. Such a telecommunications tower segment would preferably be manufactured using a single-sided mold, and more particularly using concrete with a compressive strength of 40 MPa. Such a solution is described / illustrated in FIGS. 4-7. This solution is realized, for example, by dividing the complete circle into 8 segments and making the internal cross-sectional shape octagonal, i.e. keeping the inner surface flat. The outer surface is preferably kept in a shape as depicted in FIGS. 4 to 7, ie a shape in which the cross section of the entire base section when assembled into one is circular. Of course, it is possible to make the element with more parts, but if the ground section is secured to the ground using 8 foundation piles, symmetry is achieved resulting in a more rigid structure. Is a convenient option. The number of elements can be 6, 7, 9, and 10, but the use of more parts is constrained by size and configuration requirements, and the use of fewer segments is subject to transportation restrictions. Limited. Accordingly, an object of some embodiments of the present invention is to facilitate the manufacturing process of telecommunications towers. It would also be desirable to reduce manufacturing costs. In addition or alternatively, it would be advantageous to provide a solution that does not affect the tower profile. The present invention is not limited to any diameter size of element cross-section or any wall thickness of the element, and the numerical values in each figure are only shown for a better understanding of the invention. .

  As an example of the antenna tower structure, a structure having a height of 40 m is used in each example, but the tower is by no means limited to the shape and size depicted in these figures. All other applicable antenna tower structures are 15 to 55 meters high. The minimum width size of the base section may be 5 meters, but any diameter size is possible as long as it is between 5 and 10 meters. As described above, other internal cross-sectional shapes are possible, for example, selecting 6 as the number of elements results in a hexagon. Combinations of various internal cross-sectional shapes and various external cross-sectional shapes are also possible. The outer surface portion is formed on demand and can be formed to represent the characteristics of the operator or the like, or can be formed to better fit the landscape view. The internal cross-sectional shape is formed to simplify the manufacture of the element and reduce costs. From a business point of view, an important aspect of some embodiments of the present invention is the introduction of customer-specific antenna tower shape (s) that will be the “feature” of the operator. As an alternative aspect, the antenna tower structure may form part of the billboard support. The ground section is further mounted on the foundation or is directly attached to the ground, preferably by a pile or press-fit pile / pole. Each element can be attached directly to the base or the ground, or it can be attached using, for example, a pole.

  It is worth pointing out that when the ground section is divided into a circular outer surface and an octagonal inner surface consisting of eight identical element parts with a flat inner surface, the middle area of the cross section becomes thicker. In order to reduce cost and weight, these elements are molded into a partially hollow form according to FIGS.

  This is done in view of configuration requirements and requirements. This allows the post-tension strand to pass through the center of the element, which is visible from the inside of the tower, eliminating the uneven distribution of forces. These elements are attached to each other with the aid of an attachment (see FIG. 5). This is achieved by forming at least one side of each element as a hollow that can be subsequently filled with additional mounting material such as concrete. It is preferable to cut out both sides of each element. Other attachment methods such as bolting, screwing, and gluing can also be used. In addition, metal wires or strands can be used around the outer surface to provide additional stability to the ground section.

  FIG. 1 shows an elongated cast antenna tower structure according to the prior art. This structure is developed into segments S1 to S4, and S1 is a base segment. These segments are interconnected longitudinally by a plurality of elongate fastening members (20) that together form a longitudinal interconnect structure (30) interconnecting the base segment to the terminal segment without any longitudinal gaps, Comprises a fastening member guide (50) formed in the segment wall and arranged to keep the fastening member in a predetermined configuration relative to the segment.

  FIG. 2 shows a telecommunications tower (200) comprising a plurality of telecommunications tower sections (100). The telecommunications tower section (100) may comprise a plurality of telecommunications tower segments (300). This figure provides exemplary dimensions for each part.

  FIG. 3 shows the base section (6) of the telecommunications tower (200). According to this figure, the base section (6) has a diameter of about 5000 mm and the shape when viewed from above is preferably circular. 8-12 piles can be used to attach the base section (6) to the ground. Alternatively, the base section (6) is directly molded on the ground using the foundation. Size and shape are in no way limited to 5000 mm and circular. Other shape examples include an ellipse, a square, a rotating annular shape, a triangle, a rectangle, a hexagon, and an octagon. The base section (6) includes one or more inlets (8) that allow access to the interior of the antenna tower structure 200. One or more controllable ventilation holes (5) provided in the base section (6) allow for controllable intake for air circulation causing a cooling mechanism inside the telecommunications tower (200). The base section 6 (bottom section) may be hollow and large enough to accommodate most equipment configurations in an indoor environment. The base section 6 is generally insulated and the insulator is mounted in the mold and is mounted during the molding of each section. A plurality of electrical conduits as well as other details are placed in the mold. One advantage of having a hollow structure is that a separate shelter can be avoided. As the base of the tower has a climbing prevention shape that prevents climbing naturally, it is not necessary to enclose the site. As an alternative, the base section (6) is constructed as multiple independent parts that can be assembled locally.

  FIG. 4 shows a telecommunications tower section (100) comprising a plurality of telecommunications tower segments (300). Each segment has a flat or partially flat surface (320) and a convex surface (310) on the opposite side of the flat surface. According to some embodiments, section (100) has an altered perimeter, such as one end being smaller. This shape can also resemble a cone, as indicated by the dashed circles in FIG.

  FIG. 5 shows the telecommunications tower segment (300) viewed from two different angles at two different scales. This figure also shows a mold (350) suitable for molding this segment. The upper drawing is a side view of the mold, shown with exemplary length dimensions. This length is a measurement from the first end (510) to the second end (520). For the molding of this segment, a vibration device that vibrates the mold may be used in order to realize a more uniform molding.

  The lower drawing of FIG. 5 is a side view of the segment and mold as seen from the second end (520). As an exemplary measurement, the second end (520) may have 2 meters in its widest direction. In some embodiments, there are grooves (330) on one or both sides of the segment. Grooves can be constructed by attaching attachment portions (500) to one or both sides of the mold. In order to facilitate the assembly of the sections, it is advantageous if the grooves are on both sides. Grooves are useful for connecting a segment to another segment or another structure. The connection of the segments can be made by injection, for example using concrete or some other adhesive material. Alternatively or additionally, the segments can be provided with grooves for connecting the sections of the segment to the adjacent sections.

  FIG. 6 further shows the telecommunications tower segment and the mold at two different scales as seen from two different angles. According to the embodiment shown in this figure, attachments (500) are attached to one or both sides of the mold. These attachments are attached using a joint (340). The joint (340) allows the attachment to be manipulated by creating a groove during molding and then removing the attachment by rotating the attachment around the joint so that the segment can be easily removed after completion To. Further shown in FIG. 6 is the insertion of one or more tubes (600) extending from a first end (510, shown in phantom in this figure) to a second end (520). is there. Using a tube allows the fastening member to pass through to connect the segments together. Alternatively, the cable can be passed through the tube.

  FIG. 7 further shows the telecommunication tower segment (300) and the mold (350) from two different angles, at two different scales. By inserting one or more recesses (700) into a flat or partially flat surface (320), material can be saved during molding without significant disruption. The creation of the recesses can be done by milling or by other methods of removing material from the segments. Alternatively, the recess can be created by inserting one or more foreign objects into the mold during the construction of the segment to prevent the molding material from entering the area requiring the recess.
