Further, the components described below include those which can be easily conceived by those skilled in the art and those which are substantially the same. Furthermore, the configurations described below can be combined as appropriate. In addition, various omissions, substitutions, or modifications of the configuration can be made without departing from the scope of the present invention.

  FIG. 1 is a general view of a tower-like structure using a cylindrical structure according to an embodiment. FIG. 2 is a plan view of a tower-like structure using a cylindrical structure according to the embodiment. As shown in FIGS. 1 and 2, the tower structure 1 is installed with respect to the ground GL, and the cylindrical structures 2A, 2B, 2C, the support structures 3A, 3B, 3C, the closed portion 4 and the like. , And a connecting plate 5.

  The tower-like structure 1 illustrated in FIGS. 1 and 2 is an antenna tower that has an overall height of about 90 m and supports the antenna 100 to be supported. However, the tower-like structure 1 does not use only the antenna 100 as a support target, and devices regarding the antenna and devices related to the tower, such as lightning protection equipment and aeronautical fault lights, can also be support objects.

  The cylindrical structures 2A to 2C (hereinafter, referred to simply as the “cylindrical structure 2” without distinction or integral of the cylindrical structures 2A to 2C) are supporting structures 3A to 3C (hereinafter, supporting structure) The antenna 100 is mounted at a height via the 3A to 3C without distinction or as a whole, simply via the “support structure 3”. The tower-like structure 1 includes three cylindrical structures 2A to 2C.

  As shown in FIG. 2, the cylindrical structures 2 are spaced apart from each other and are erected from the ground GL, and the lower ends thereof are fixed to the substructure 6. Here, the foundation structure 6 is made of, for example, reinforced concrete, and is configured of a main body portion 61 and a fixing portion 62. The main body 61 is a base of the tower structure 1 and is buried in the ground GL.

  The fixed portions 62 are equally spaced (120 degrees) circumferentially around a reference point (a reference line (dotted line shown in FIG. 1)) O in a horizontal plane including a horizontal direction orthogonal to the vertical direction of the tower structure 1 The lower end portions of the cylindrical structures 2A to 2C are respectively fixed to the main body portion 61 so as to be separated from each other.

  The cylindrical structure 2 is divided into an inclined cylindrical portion 21 and a vertical cylindrical portion 22 upward from the ground GL, as shown in FIG. 1. In the cylindrical structure 2, a necked portion 23 is formed at a portion where the inclined cylindrical portion 21 transitions to the vertical cylindrical portion 22. That is, the constriction portion 23 is formed between the inclined cylindrical portion 21 and the vertical cylindrical portion 22. Therefore, the cylindrical structures 2A to 2C are bent in a square shape when viewed from the direction perpendicular to the vertical direction. The inclined cylindrical portions 21 of the cylindrical structures 2A to 2C approach each other as they move upward from the ground GL. It is preferable that the ratio of the length in the up-down direction of the inclined cylindrical part 21 and the vertical cylindrical part 22 is about 2: 1 to 4: 1.

  In the inclined cylindrical portion 21 of the cylindrical structures 2A to 2C, as shown in FIG. 2, lower end portions, that is, lower end portions of the respective cylindrical structures 2A to 2C are equally spaced in the circumferential direction (120 degrees Spaced apart). The inclined cylindrical portions 21 gradually approach each other toward the reference point O when viewed from above and below in the middle from the lower side end to the upper side end. Here, each of the cylindrical structures 2A to 2C has the same structure although the angles from the reference point O are different when viewed in the vertical direction.

  The cylindrical structures 2A to 2C are configured by connecting a plurality of cylindrical members 24 in the serial direction. Here, in order to avoid complication of the reference numerals, the cylindrical member 24 is shown using the same reference numerals. The cylindrical member 24 is a steel pipe having a circular cross-sectional outer peripheral shape. In the case of the tower-like structure 1 having a length of, for example, about 10 m and a total height of about 90 m, each of the cylindrical members 24 has about 10 cylindrical members 24 in series in the cylindrical structures 2A to 2C. Concatenated in directions. In addition, the cross-sectional outer periphery shape of the cylindrical member 24 is not restricted circularly, An ellipse and a polygon may be sufficient. That the cylindrical members 24 are connected in the series direction means that the mutually opposing annular end surfaces of the cylindrical members 24 connected are joined.

The connection plate 5 has a configuration to be described in detail later, so that a connection structure is realized that is easy to perform on-site work and that is easy to correct an error in construction accuracy. In addition, although the connection method using the connection plate 5 can be applied to all the connection locations of the cylindrical members 24 in the vertical cylindrical portion 22, the connection method using the connection plates is necessarily applied to all the connection locations. There is no need. According to the required level of rigidity in the entire tower-like structure 1, the connection method using the connecting plate 5 can be applied where necessary.

  The cylindrical structures 2A to 2C communicate the internal space of the cylindrical member 24 in the vertical direction to form internal spaces communicating from the lower end to the upper end in the vertical direction. . In the cylindrical structures 2A to 2C, the first opening 25 is formed on the ground GL side. The first opening 25 allows an operator to enter and exit from the ground GL to the internal space of each of the cylindrical structures 2A to 2C.

  Moreover, 2nd opening part 26 corresponding to the support structure 3 is formed in cylindrical structure 2A-2C, respectively. That is, the second openings 26 in the present embodiment are respectively formed corresponding to the support structures 3A to 3C in one cylindrical structure 2A to 2C. The second opening 26 allows an operator to enter and exit each of the support structures 3A to 3C from the internal space of the cylindrical structures 2A to 2C.

  Since the first opening 25 and the second opening 26 communicate with each other through the internal space, the operator can attach the elevating ladder used by the operator to the internal space, thereby the operator can support the ground GL and the support structure. You can go back and forth between things 3.

  Further, in the internal space portion of the cylindrical structures 2A to 2C, a cable for supplying power or transmitting a signal to an apparatus including the antenna 100 installed on the support structures 3A to 3C is provided. Can also be used. By arranging the cable in the internal space of the cylindrical structures 2A to 2C, the influence of the external environment on the cable can be suppressed, and the durability of the cable can be improved. Further, since the worker can maintain the cables and the like while staying in the internal space of the cylindrical structures 2A to 2C, the work becomes easy and the safety is also improved.
