Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a metal fitting for joining a warning sign or the like displayed on a steel tower in a steel tower that supports a power transmission line.

[0002]

[Prior art]

 Various fittings for joining the marker to the steel tower through the structural members of the steel tower have been proposed by the applicant of the present application. However, when it is attached to an angle material used as a diagonal material, Depending on the convenience of arranging the sign in the central part of the steel tower, it is better to select the joining means individually for the guide rail etc. It is economically advantageous because it can be joined without requiring.

[0003]

[Problems to be solved by the device]

 According to the present invention, when the angle member as the diagonal member is inclined to one of them at a required arrangement angle and is installed as a single member, it can be attached to the angle member corresponding to a wide range of arrangement angles. The present invention provides a metal fitting for a steel tower marker.

[0004]

[Means for Solving the Problems]

 The metal fittings for the steel tower marker of the present invention have a connecting plate made of a vertically long flat plate having a required width and a required thickness, with the width face as the front face, facing each other at a required interval, and the through holes are formed in the upper and lower portions of both the connecting plates. At the same time, at the center of the vertical rear surface, arms are extended from the left and right toward the inside rear, and a horizontally long attachment plate of the required width and thickness is joined between the rear ends of both arms. The fitting main body is formed by vertically penetrating one of the left and right sides, and the other side by an arc groove of a predetermined width with a predetermined radius of curvature centered on any of the through holes. It comprises a through-hole on the plate, and a metal stopper having a long screw shaft and a short screw shaft, which are inserted into the circular arc groove, integrated in a fork-like manner in a diagonal portion.

[0005]

[Action]

 Both joining plates are used for joining the signs, one of the front and back surfaces of the attachment plate is brought into contact with the vertical part of the angle member, and the fastener is inserted into the through hole and arc groove of the attachment plate, and the nut is attached. The angle member is clamped via.

[0006]

【Example】

 The metal fitting 1 of the steel tower marker of the present invention (hereinafter simply referred to as the metal fitting a) will be described by way of example. As shown in FIG. 1, the metal fitting body 1 is a flat plate having a required width, a required thickness, and a vertically long length. Through a through hole 2 vertically, and a pair of joining plates 3 facing each other with a width face as a front face at a required interval, and one end of the joining plate 3 is joined to a central portion of a rear face of the joining plate 3 from the left and right sides to the inner rear side. Both arms 5 which are bulged toward the other end and are provided with a bent curved surface 4 parallel to the front surface of the joining plate 3 and a horizontally long flat plate having a required width and a required thickness, and through holes formed on the left and right sides in the longitudinal direction. 6 through, and a circular arc groove 7 having the same width as the diameter of the through hole 6 is formed in a divergent shape with a predetermined radius of curvature centering on the lower through hole 6 from the upper right side to the lower side. And the attachment plates 8 formed by joining the left and right back surfaces to the respective bent curved surfaces 4 of the arm 5, Ingredients 9 are those made by concatenating bent to one body both the long threaded shaft 10 and a short screw shaft 11 by the diagonal member 12.

As shown in FIG. 2 as an example, in the joining metal fitting a thus configured, the angle member 13 directs the horizontal portion 14 toward the outer surface of the steel tower (not shown), and the required installation is performed from the upper right to the lower left. In the case of mounting at an angle, the surface of the attachment plate 8 is brought into contact with the vertical portion 15 of the angle member 13, the long screw shaft 10 of the fastener 9 is inserted from the surface side into the through hole 6 above, and The screw shaft 11 is inserted into the circular arc groove 7, and a nut is screwed into both screw shafts 10 and 11 from the rear surface side of the attachment plate 8. When the nut is tightened, the diagonal member 12 is a horizontal portion of the angle member 13. The metal fitting a is attached to the angle member 13 by pressing 14 and sandwiching the angle member 13 between the attachment plate 8 and the diagonal member 12. With respect to the joint fitting a thus attached, the marker body 16 is fitted with through holes 17 penetrating up and down on the left and right respectively to the through holes 2 of the joint plate 3, and a general bolt and nut (not shown) are used. It is joined by various fastening means.

Further, as shown in FIG. 3, when the angle member 13 is attached with the horizontal portion 14 facing the inner surface of the steel tower from the upper left to the lower right at a required arrangement angle, the angle member 13 is vertically attached. The rear surface of the attachment plate 8 is brought into contact with the portion 15, and the long screw shaft 10 of the stopper 9 is inserted from the rear surface side into the arc groove 7, and the short screw shaft 11 is inserted into the lower through hole 6 so that both screws When the nuts are screwed onto the shafts 10 and 11 from the surface side of the attachment plate 8 and the nuts are tightened, the diagonal member 12 presses the horizontal portion 14 of the angle member 13, and as described above, The joining metal fitting a is attached to the angle member 13 by gripping with friction, and the marking body 16 is likewise joined to the joining plate 3 with bolts and nuts. The radius of curvature for forming the circular arc groove 7 is selected because the distance between the inner end of the through hole 6 and the inner end of the circular arc groove 7 is selected to be slightly longer than the length of one side of the angle member 13. Several types are prepared corresponding to the angle member 13. Further, the formation of the circular arc groove 7 is not limited to that shown in this embodiment, and the same effect can be obtained even if the circular arc groove 7 is formed with a predetermined radius of curvature centering on the through hole 6 at the upper side. Of course.

[0009]

[Effect of device]

 As described above, according to the metal fitting for a steel tower marker of the present invention, the marker is secured at a fixed position to the angle member as one diagonal member regardless of the arrangement angle. There is an effect that can be done.
