[0014] (Support pillar 20) As shown in FIG. 1, FIG. 2, and FIG. 4, a support column 20 for installing the antenna 14 is installed on the upper surface of the steel foundation 18, and the support column 20 extends in the vertical direction. The support column 20 has a column portion 20a extending in the vertical direction, and the column portion 20a is made of, for example, a round pipe-shaped steel tube. The support column 20 has a rectangular connection plate portion 20b joined to the lower end surface of the column portion 20a by welding or the like, and the connection plate portion 20b is joined to the upper surface of the steel foundation 18 by a plurality of bolts. The support column 20 has a circular connection plate portion 20d joined to the upper end surface of the column portion 20a by welding or the like. The support column 20 may be composed of a plurality of divided columns divided along the vertical direction. A plurality of footrests may be provided at intervals in the vertical direction on the column portion 20a.

[0015] (Paul 22) 2 to 8, four cylindrical poles 22 extending in the vertical direction are arranged at intervals around the support column 20, and each pole 22 is made of, for example, a round pipe-shaped steel tube.

[0028] (Installation of antenna 14 and wireless communication device 16) 5 to 7, the mounting of the antenna 14 and the wireless communication device 16 on the base station mount 12 will be briefly described.

[0029] 1, the support pole 20 is provided with a plurality of support arms 52, and the antenna 14 is provided on the plurality of support arms 52. In other words, the antenna 14 is mounted on the support pole 20 via the plurality of support arms 52.

[0030] A first mounting bracket 54 for installing the wireless communication device 16 is detachably provided on each pair of first horizontal connecting members 30 facing each other in the vertical direction via a plurality of U-bolts 56. In other words, the wireless communication device 16 is installed on each pair of first horizontal connecting members 30 facing each other in the vertical direction via the first mounting bracket 54 and the plurality of U-bolts 56. Furthermore, a second mounting bracket 58 for installing the wireless communication device 16 is detachably provided on each pair of second horizontal connecting members 38 facing each other in the vertical direction via a plurality of U-bolts 60. In other words, the wireless communication device 16 is installed on each pair of second horizontal connecting members 38 facing each other in the vertical direction via the second mounting bracket 58 and the plurality of U-bolts 60.

[0031] In the base station stand 12, as described above, the support pillars 20 are installed on the upper surface of the steel foundation 18. Each pair of horizontally adjacent poles 22 is integrally connected by a first connecting member 28. Each pair of vertically adjacent poles 22 is integrally connected by a second connecting member 36. Each pole 22 and the support pillar 20 are integrally connected by a third connecting member 46. Therefore, not only the support pillars 20 but also each pole 22, each first connecting member 28, and each second connecting member 36 can be integrated with the steel foundation 18. This makes it possible to increase the support rigidity of the base station stand 12 while reducing the installation space for the base station stand 12.

[0032] In particular, since each first connecting member 28 has a pair of first horizontal connecting members 30 and first diagonal connecting members 32, it is possible to increase the support rigidity of each first connecting member 28. Since each second connecting member 36 has a pair of second horizontal connecting members 38 and second diagonal connecting members 40, it is possible to increase the support rigidity of each second connecting member 36. Since each third connecting member 46 has a pair of third horizontal connecting members 48 and third diagonal connecting members 50, it is possible to increase the support rigidity of each third connecting member 46. This makes it possible to further increase the support rigidity of the base station stand 12.

[0033] Furthermore, since the four poles 22 are located at the corners of a square when viewed in a plane, the support rigidity of the base station stand 12 can be increased compared to when the four poles 22 are located at the corners of a rectangle other than a square when viewed in a plane.

[0034] Therefore, according to the embodiment of the present invention, it is possible to stabilize the installation state of the antenna 14 and the wireless communication device 16 while reducing the space required for the base station stand 12, in other words, reducing the space required for the mobile phone base station 10.

[0035] In the base station stand 12, as described above, four jack bases 24 that support the poles 22 from below are installed around the steel foundation 18 on the floor surface of the rooftop RF of the building. Therefore, when raising the height of the rooftop RF for waterproofing, the installation height of each jack base 24 can be adjusted according to the raising height. As a result, according to the embodiment of the present invention, the workability of raising the height of the rooftop RF can be improved.

[0036] 〔summary〕 A base station stand according to a first aspect of the present invention is a base station stand for installing a mobile phone base station on the roof of a building, comprising: a steel foundation installed on the floor of the roof, a support column installed on the steel foundation for installing an antenna, four poles standing at intervals around the support column and positioned at four corners of a rectangle in a plan view, a first connecting member provided to connect between each pair of adjacent poles in a horizontal direction, which is one of the horizontal directions, a second connecting member provided to connect between each pair of adjacent poles in a vertical direction, which is one of the horizontal directions, and a third connecting member provided to connect between each pole and the support column. A wireless communication device to be connected to the antenna is installed on at least one of the multiple first connecting members and the multiple second connecting members.

Each pair of horizontally adjacent poles is connected by the first connecting member. Each pair of vertically adjacent poles is connected by the second connecting member. Each pole and the support column is connected by the third connecting member. Therefore, not only the support columns but also each pole, each first connecting member, and each second connecting member can be integrated with the steel foundation. This makes it possible to increase the support rigidity of the base station stand while reducing the installation space of the base station stand. As a result, it is possible to achieve space saving for the mobile phone base station while stabilizing the installation state of the antenna and the wireless communication device.

[0038] The base station stand of aspect 2 of the present invention may be the same as that of aspect 1, and further include four jack bases that are installed at intervals around the steel foundation on the rooftop floor and support the pole from below.

Each second connecting member may include a pair of second horizontal connecting members extending vertically and facing each other in the vertical direction, and a second inclined connecting member arranged between the pair of second horizontal connecting members and inclined with respect to the horizontal direction.

[0041] According to the above configuration, since each first connecting member has a pair of the first horizontal connecting member and the first diagonal connecting member, the support rigidity of each first connecting member can be increased. Since each second connecting member has a pair of the second horizontal connecting member and the second diagonal connecting member, the support rigidity of each second connecting member can be increased. This can further increase the support rigidity of the base station stand.

[0042] A base station stand according to aspect 4 of the present invention, in any of aspects 1 to 3, may have such that each third connecting member has a pair of third horizontal connecting members extending horizontally and facing each other in the vertical direction, and a third inclined connecting member arranged between the pair of third horizontal connecting members and inclined with respect to the horizontal direction.

[0043] According to the above configuration, since each third connecting member has a pair of the third horizontal connecting member and the third diagonal connecting member, the support rigidity of each third connecting member can be increased, thereby further increasing the support rigidity of the base station stand.

[0044] A base station stand according to a fifth aspect of the present invention is based on any one of the first to fourth aspects, and the four poles may be located at the corners of a square in a plan view.

[0045] According to the above configuration, the support rigidity of the base station stand can be increased compared to a case in which the four poles are located at the corners of a rectangle other than a square in a plan view.

[0048] In this specification, an example has been described in which one mobile phone base station 10 has four poles 22, but the number of poles 22 may be three, five, or the like. The number of poles 22 can be selected as any number equal to or greater than three depending on the environment of the installation location of the mobile phone base station 10. Any one of the multiple poles 22 may also function as a support column. This allows the present invention to be used when, for example, the mobile phone base station 10 is installed at the edge of the rooftop of a building.

[0049] [Additional Notes] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in the embodiments are also included in the technical scope of the present invention.
