Description

  The present invention relates to a power pole support device that supports a main (electric) pole by a tilted support.

  There is known a structure in which a band body is fastened to each of a main pillar and an inclined column supporting the main pillar with a tightening bolt, and connecting pieces constituting the band body are fastened to each other with the tightening bolt. (For example, patent document 1).

Japanese Utility Model Publication No. 60-12443

  In the conventional example, the connection between the band bodies (the main pillar and the column) is indispensable for supporting the main pillar, and means for connecting the connection piece constituting the band body. It is necessary to prepare the band body itself, which is not economical, and since the connecting piece is connected by a single assembly shaft (tightening bolt), the inclination angle of the column with respect to the main column is It will be subject to restrictions and will be subject to application restrictions.

  The present invention pays attention to the disadvantages of such a conventional example, and can use an existing band body in which a plurality of band pieces are fastened to a power pole with tightening bolts, and the degree of freedom in selecting the inclination angle of the column with respect to the main pole. It was invented for the purpose of providing a certain utility pole support device.

  A band body fastened with tightening bolts to each of the main pillar and the inclined strut supporting the main pillar is installed, and one end portion of the connecting piece interposed between the band bodies is attached to the one band body with the tightening bolt. The other end portion is pivotally attached to the other band body with the tightening bolt.

  According to the present invention, the connecting pieces are assembled using the tightening bolts for tightening the band pieces constituting the band body, and the main pole side band body and the post side band body are connected. It is economical because there is no need to prepare a special band body because it is possible to obtain a power pole support device that uses the band body that is tightened to the power pole with tightening bolts as it is, and also suitable for inventory management. It is.

  In addition, since the band bodies, that is, the main column and the support column are connected by two axes, the inclination angle of the support column with respect to the main column can be freely set, and therefore the main column can be reliably set according to the site environment. An electric pole support device that can be supported can be provided.

  FIG. 1 is a front view, FIG. 2 is a cross-sectional view taken along the line aa of FIG. 1, and FIG. 3 is a perspective view of a connecting piece.

  The utility pole support device according to the present invention includes the band bodies Ba and Bb, which are fastened to the main pole D and the inclined column S, and the band bodies Ba and Bb interposed between the band bodies Ba and Bb. It is constituted by a connecting piece 1 that connects the column D and the inclined column S.

  The band bodies Ba and Bb have a pair of band receiving pieces 2 and 2 'whose ends are connected to each other by a connecting bolt 3 and a connecting nut 4 and between the elastic band receiving pieces 2a and 2a and 2'a and 2'a. The tightening bolt 5 is made up of a so-called four-piece type known structure in which a tightening nut 6 is screwed and tightened to a bolt tip protruding from one of the tightening receiving pieces 2a, 2'a. The tightening bolt 5 provided in the tightening receiving piece 2a, 2a on the support column S side of the band body Ba on the main body D side passes through the tightening bolt 5 so that one end of the connecting piece 1 is connected to the tightening receiving portion. The other end of the connecting piece 1 is clamped to the clamp receiving piece 2a, 2a on the main column D side of the band body Bb on the inclined column S side. Similar to the main column D side, the tightening bolt 5 is passed through the bolt 5 so that the tightening receiving portion 2a, arranged by interposing between 2a, it is obtained the connecting piece 1 with two band members Ba through, Bb i.e. by connecting the pillars D and inclined struts S and Example device.

  The connecting piece 1 is formed by bending a steel plate and bends one end side of the side piece 1b, 1b and the side piece 1b, 1b opposite to the central piece 1a at a right angle to face the central piece 1a. The side piece 1b having a reinforcing piece 1c, 1c with a part of the opening end a on the side closed, is formed of a slightly triangular box-like body, and is adjacent to the corner that hits the apex of the triangle Through holes 7, 7 are provided at one corner, and the tightening bolt 5 is passed through the through holes 7, 7 and is interposed between the band bodies Ba, Bb.

  The reason why the reinforcing piece 1c is provided on the connecting piece 1 is to prevent the connecting piece 1 (box-like) from being crushed by the tightening pressure when the tightening nut 6 is screwed to the tightening bolt 5.

  Then, the band pieces 2 and 2 ′ are connected to each other by the connection bolt 3 and the connection nut 4, and the band pieces 2 ′ side of the pair of connection bodies are assembled by the tightening bolts 5 and the tightening nuts 6. (With the tightening bolt 5 on the band piece 2 side omitted), and the connecting piece 1 is interposed between the tightening receiving piece 2a, 2a of the band piece 2 of the band bodies Ba, Bb. The tightening bolt 5 is inserted between the tightening pieces 2a and 2a through the corresponding through holes 7 provided in the screw hole, and the tightening nut 6 is screwed into the bolt tip protruding from the one piece 2a. A band structure in a state where the band bodies Ba and Bb are connected to each other is obtained, and one band body Ba side of the band structure is fitted to the front end side of a main column D that is erected in advance on the site, The tip of the column S arranged (inclined) in the crossing direction with respect to the column D The other band body Bb side is fitted to the end side so that the radial direction of the band bodies Ba and Bb is orthogonal to the axis of each column D and S (at this time, it is necessary Accordingly, the connection bolt 3 is replaced with an appropriate one of the adjustment holes 9 provided in the band pieces 2 and 2 ', and is made to correspond to the column diameter), and the nuts 4 and 6 are tightened to tighten the embodiment device. To get.
