Description

  The present invention relates to a pole mount for attaching an article to a columnar object such as a utility pole.

  In recent years, the technology of mobile terminals has advanced, and the demand for mobile terminals has increased. Along with this, the establishment of base stations at various locations is underway. The number of base stations to be installed is very large, and there is a demand for simple installation at a low cost.

  Columns such as utility poles are widely used as places for installing base stations. When installing a base station on a columnar object, a column base made up of a frame formed of plate material and an attachment member attached to the frame body is fixed to the columnar object with a fastening band or the like, and an antenna, Attach the wireless device and power supply unit. In general, a wireless device other than an antenna, a power supply device, and the like are housed and attached in a casing (article) having a shape close to a metal rectangular parallelepiped.

  In addition, when installing a base station on a columnar object, it is required to attach a pedestal at a predetermined height or higher from the ground so that a person on the ground does not touch an article of the base station. Therefore, when a base station is installed and when the base station is maintained, a worker works at a high place using a ladder or the like. In order to facilitate the work of workers at a high place, a work scaffold is provided on the gantry. The worker moves to the scaffold using a ladder or the like, and then performs various operations on the scaffold.

  Depending on the communication standard of the mobile terminal and the frequency range of the radio wave used, the configuration of the articles forming the base station attached to the columnar object is different. For example, a conventional base station has two cases for housing articles other than antennas, whereas a base station with another new specification may have three cases. is there.

  Even when installing base stations with different numbers of housings to be mounted in this way, it is desirable to reduce the installation cost by using a common frame and scaffolding to form a column base.

  Patent Document 1 describes a mount for attaching three housings at different positions in the circumferential direction of a columnar object, specifically, 90 degrees. In the case of this gantry, it is necessary that the width of the case that can be attached is smaller than the diameter of the columnar object. In order to attach a case with a width larger than the diameter of the columnar object to the frame, the frame needs to have a double structure so that the width of the mounting surface is larger than the diameter of the columnar object, and the structure is complicated and the cost increases. .

  The present invention uses a common frame body and scaffolding to realize a column base that allows easy access to each housing by standing on the scaffolding even when the number of articles (housings) to be mounted is different. With the goal.

  The column mount according to the present invention enables the scaffold to be attached to the central part of the short side and the long side of the rectangular frame, and when the number of articles (housings) to be attached is two, When the scaffold is attached to the short side and the frame is attached to the columnar object so that the long side of the rectangle is parallel to the vertical axis of the columnar object, and the number of articles (housings) to be attached is three The scaffold is attached to the center of the long side of the rectangle of the frame so that the long side of the rectangle is perpendicular to the vertical axis of the column.

  That is, the column post of the present invention is a column post for attaching an article to a vertically erected columnar article, and includes a rectangular frame and a scaffold attached to the frame. The frame includes a frame fastening portion for attaching to the frame, and the frame includes a scaffold fastening portion for attaching the scaffold to a rectangular short side and a central portion of the rectangular long side, and the frame has a long rectangular side. When attaching to a pillar so that it is parallel to the vertical axis of the pillar, attach a scaffold to the short side of the rectangle, and when attaching the frame to the pillar so that the long side of the rectangle is perpendicular to the vertical axis of the pillar The scaffolding is attached to the long side of the rectangle.

  According to the present invention, the attachment position of the scaffold to the frame can be changed depending on whether the long side of the rectangular shape of the frame is parallel to the vertical axis of the columnar object or the vertical direction of the columnar object. When the body is attached, since three housings are arranged in the horizontal direction, any housing can be accessed from a scaffold provided at the center of the long side of the rectangular body. When two housings are attached, two two housings are arranged in the vertical direction, but since the distance from the scaffold to the upper housing is small with two, the rectangular short side of the frame body It is also possible to access the upper housing from the scaffolding provided on the top.

  The scaffold fastening portion of the frame body and the frame fastening portion of the scaffold are through holes, and the frame body and the scaffold are fastened by bolts and nuts.

  The column mount further includes two band fastening members for attaching the column mount to the columnar object, and two bands for banding the two band fastening members to the columnar object, and a frame and The scaffold is attached to two band fastening members.

  The frame includes a band member fastening portion for attaching a band fastening member to a rectangular short side and a central portion of the rectangular long side, and the scaffold attaches the band fastening member to a side opposite to the frame fastening portion. A scaffold band fastening part is provided.

  The frame includes a safety hook portion that hangs a safety hook connected to an operator on one long side of the rectangle.

  The frame is divided into three parts in the long side direction. When the frame is attached to the columnar object so that the long side of the rectangle is parallel to the vertical axis of the columnar object, the upper two parts of the three parts When two articles (housing) are mounted on the frame and the frame is attached to the columnar object so that the long side of the rectangle is perpendicular to the vertical axis of the columnar object, three articles are mounted on the three parts. To do.

  According to the column mount of the present invention, it is possible to attach two and three articles (housings) using a common frame and scaffolding, and in each case, each article (housing) from the scaffolding. ) Can be easily accessed.
