Description

  The present invention relates to an object mounting bracket for mounting an object such as various devices to a steel tower for power transmission and distribution.

  Conventionally, in pylons for power transmission and distribution, troubles caused by birds such as crows flying or nesting (for example, by using a conductive material such as a metal hanger or iron wire for the nest, In order to prevent occurrence of short-circuiting or the like due to material falling or coming into contact with the facility, or occurrence of fecal damage), bird damage prevention devices are appropriately attached.

  Also, in such steel towers, taking advantage of the high place, a sign board showing a symbol mark or slogan, a warning character or figure for preventing an electric shock accident, an antenna for a mobile phone, a thermometer / hygrometer Various objects such as observation devices related to the weather, etc. may be attached.

  Objects such as these various devices and instruments are attached to a steel tower or the like using, for example, an object mounting bracket disclosed in Patent Document 1. As shown in FIG. 4, the object mounting bracket 100 includes an L-shaped bracket body 10 having an L shape, and a bolt 2 and a nut 3 that engage with the L-shaped bracket body 10.

  The L-shaped bracket main body 10 has one piece 10a provided with an object attachment piece 13 for attaching an object (not shown) such as various devices or instruments at one end, and the other provided continuously with the other end of the one piece 10a. The one piece 10a and the other piece 10b are bent at a substantially right angle. In addition, a long hole 11 extending in the longitudinal direction is formed in one piece 10a, and a longitudinal direction in which a tip (an end opposite to the one piece 10a) is opened in the other piece 10b. An incision groove 12 is provided to extend to.

  The object mounting piece 13 extends from one end of one piece 10a of the L-shaped bracket body 10 and is bent to the opposite side of the other piece 10b, and is connected to the first piece 13a. The second piece 13b is bent to the side facing the one piece 10a. In other words, at one end of the one piece 10a of the L-shaped metal fitting body 10, a U-shaped object attachment piece 13 extending from the one end is provided. The first piece 13a and the second piece 13b are provided with attachment holes 14a and 14b, respectively, which are bolt insertion holes for fixing an object to be attached. In addition, the L-shaped metal fitting body 10 provided with such an object mounting piece 13 is formed in series by, for example, bending a hard flat bar in a right angle direction at a desired location.

  The bolt 2 is welded and fixed to the bolt head 4 in a state where the slide member 101 reciprocating along the long hole 11 of the one piece 10a is inserted on the bolt head 4 side. In addition, a slide member 101 that reciprocates along the cut groove 12 of the other piece 10b described above is loosely inserted on the nut 3 side. Such a slide member 101 is, for example, an L-shaped chevron member made of hard flat steel, and is provided with a small projection 101a for sliding which engages with the long hole 11 or the cut groove 12 at both ends of the skirt, A bolt insertion hole 101b is formed in one piece.

  Then, after the bolt 2 having the slide member 101 fixed to the bolt head 4 is inserted into the long hole 11, the other slide member 101 is loosely inserted from the tip of the bolt 2, and then the flat washer 102 and the spring washer 103 are interposed. Then, each of the lock nut 3a and the tightening nut 3b is screwed onto the tip of the bolt 2 in advance.

  Further, the bolt 2 is cut so that the slide member 101, the washers 102 and 103, the lock nut 3 a, and the tightening nut 3 b are positioned outside the other piece 10 b of the L-shaped metal fitting body 10, and the groove 12 from the opening portion of the groove 12. After being inserted into the slide member 101, the slide member 101 is set in the groove 12 via the small protrusion 101a, and then assembled by tightening the lock nut 3a and the tightening nut 3b.

  At this time, it is arranged so that an angle member (not shown) in a steel tower or the like to be fixed is positioned on the inner peripheral side of the L-shaped bracket body 10, and the engagement position of the bolt 2 with respect to the L-shaped bracket body 10 is moved (adjusted). The object mounting bracket 100 can be fixed to the angle member by sandwiching the angle member between the L-shaped bracket main body 10 and the bolt 2.

  By the way, the object mounting bracket 100 described above basically uses an angle material as a fixing target. However, in recent years, steel towers and the like to be fixed are often used with members having a circular cross section on the outer periphery, such as cylindrical shapes such as pipe materials and utility poles as well as angle materials. ing. When such a member having a circular cross section is an object to be fixed, it is difficult for the object mounting bracket 100 as in Patent Document 1 to be firmly fixed to the object to be fixed (that is, securely fixed), Fixed reliability could not be secured.

  Therefore, conventionally, by using an attachment band that can be attached in a state of being wound around the outer periphery of the utility pole, such as the utility pole band described in Patent Document 2, the outer periphery is fixed to a fixed object having a circular cross section. I was trying to ensure the condition.

  However, in the case of such a band-shaped mounting bracket as in Patent Document 2, since there is no versatility with respect to the size of the fixed object, it is necessary to prepare a mounting band corresponding to the size of the fixed object. There was a problem that increased.

  In addition, in the case of such a band-shaped mounting bracket, the structure is such that both ends of the band wound along the outer periphery of the fixing target are bolted, and thus it can be said that the fixing target is not necessarily firmly fixed to the fixing target. It was difficult.

  The present invention has been made in view of the above-described problems, and can be firmly and reliably fixed to an object whose outer periphery is circular in cross section regardless of its size, and various types of steel towers for power transmission and distribution, etc. An object of the present invention is to realize an object mounting bracket capable of securing the mounting state of an object such as a device.

That is, the object mounting bracket 1 of the present embodiment has a point that a pair of bolts 2 and nuts 3 are provided with respect to an L-shaped bracket body 10 as an L-shaped bracket body, and the pair of bolts 2 and 2 are almost identical. It differs from the object mounting bracket 100 described above in that the pressing member 5 that is orthogonal and disposed between the bolts 2 and 2 is provided, and the L-shaped bracket body 10 is configured in substantially the same manner. . Therefore, it is possible to reduce the cost in that the L-shaped metal fitting body 10 can be used.

  Specifically, as shown in FIGS. 1 and 2, the object mounting bracket 1 of the present embodiment is connected to one piece 10a provided with an object attachment piece 13 at one end and the other end of the one piece 10a. L-shaped metal fitting body 10 formed by bending long holes 11 and 12 extending in the longitudinal direction in one and the other pieces 10a and 10b, respectively. And inserted into the long holes 11 and 12 of the other piece 10a and 10b, and is reciprocally engaged along the long holes 11 and 12, respectively. And fixing means (details will be described later) for fixing to the pipe material P in a steel tower or the like.

  In addition, it is preferable here that the long hole 12 of the other piece 10b in the L-shaped metal fitting body 10 is a cut groove having an open end. Therefore, although this embodiment demonstrates as the groove | channel 12, this invention is not limited to this.

  Such a fixing means includes a first bolt 2 inserted through the long hole 11 of one piece 10a in parallel with the other piece 10b, and a second bolt inserted through the groove 12 of the other piece 10b in parallel with the one piece 10a. The pipe material P is disposed between the bolt 2 and the first and second bolts 2, 2 on the side where the first and second bolts 2, 2 are orthogonal to each other and between the first and second bolts 2, 2. And the first and second nuts 3 and 3 screwed to the first and second bolts 2 and 2, respectively.

  The pressing member 5 includes a first surface 51 having an insertion hole 51a through which the first bolt 2 inserted through the elongated hole 11 of the one piece 10a is inserted, and the other piece 10b. The second bolt 2 inserted through the groove 12 is connected to the second surface 52 provided with an insertion hole 52a through which the bolt head 4 is disposed, and the first surface 51 and the second surface 52 are connected. And it consists of the connection part 53 curved along the outer peripheral surface of the pipe material P as fixation object.

  The object mounting piece 13 extends from one end of one piece 10a, is bent to the opposite side of the other piece 10b, and is connected to the first piece 13a. 10a and a second piece 13b bent to the opposite side, and the first piece 13a and the second piece 13b are provided with attachment holes 14a and 14b for fixing an object to be attached, respectively.

  As described above, according to the object mounting bracket 1 of the present embodiment, the cost can be reduced by making the conventional object mounting bracket 100 and the L-shaped bracket body 10 common (that is, applicable). Yes, the positions of the first and second bolts 2 and 2 with respect to the long hole 11 and the groove 12 of the L-shaped metal fitting body 10, and the screws of the first and second nuts 3 and 3 with respect to the first and second bolts 2 and 2. Depending on the combined state, the pipe member P is sandwiched between the connecting portion 53 of the pressing member 5 and the inner peripheral surface of the L-shaped bracket body 10, and the object mounting bracket 1 is securely and securely attached to the pipe member P. It can be firmly fixed. As a result, an object that can be firmly and reliably fixed to an object whose outer periphery is circular in cross section regardless of its size, and that can secure the attachment state of objects such as various devices to a power transmission / distribution tower, etc. Mounting brackets can be provided.

  Note that the fixing means is not limited to the above-described configuration. For example, as shown in FIG. 3 in which the same reference numerals are assigned to the corresponding parts as in FIG. 2, the pipe member P as a fixing target is provided on the pressing member 5. It is good also as providing the 1st holding | maintenance part 6 hold | maintained along the outer periphery.
