The reinforcing wire rod 13 is fixed to the reinforcing member 11 in a state where a predetermined tension is applied.

FIG. 2 is an enlarged view of part A of FIG. 1, and is an enlarged view of the reinforcing member 11. Since the lower reinforcing member 11 is vertically symmetrical with the upper reinforcing member 11, the description thereof will be omitted.

The reinforcing member 11 is composed of a pair of sandwiching members 15, a connecting member 21, and the like. FIG. 3 is a perspective view of the sandwiching member 15. The sandwiching member 15 includes a plate-shaped sandwiching portion 18 that is substantially parallel to the upper and lower sides, and a pair of plate-shaped arm portions 17 that connect the upper and lower sandwiching portions 18 in a direction substantially perpendicular to the plate-shaped sandwiching portion 18. The arm portion 17 may be one, or may be two or more. Further, in order to reduce the weight, the arm portion 17 is provided with a hole. If the wire rod fixing portion 19 is directly arranged on the sandwiching portion 18, the arm portion 17 is not always necessary.

A wire rod fixing portion 19 is provided in the vicinity of the tip portion of the arm portion 17. The wire rod fixing portion 19 is a substantially tubular member, and is arranged in a direction substantially parallel to the connecting direction of the upper and lower sandwiching portions 18. A reinforcing wire rod 13 is inserted through the wire rod fixing portion 19, and is fixed to the upper and lower reinforcing members 11 with, for example, a nut or the like.

A recess 23 is provided on one side of the sandwiching portion 18. The recess 23 is provided in the sandwiching portion 18 in a notch shape. The recess 23 is composed of a portion substantially parallel to the width direction (left-right direction) and a tapered portion formed on both sides thereof so as to widen in the left-right direction.

Connecting portions 27 are provided on both sides of the sandwiching portion 18. The connecting portion 27 is a substantially tubular member, through which the connecting member 21 (see FIG. 2) is inserted. Further, a female screw portion 29 is provided in the vicinity of the central portion of the recess 23 of the sandwiching portion 18. That is, the female screw portion 29 is provided behind the portion substantially parallel to the width direction in the vicinity of the central portion of the recess 23 described above.

As shown in FIG. 2, the support column 3 is sandwiched by a pair of sandwiching members 15. The sandwiching members 15 are arranged so that the recesses 23 face each other. In this state, the sandwiching portion 18 is connected to the sandwiching portion 18 of the other sandwiching member 15 facing each other by the connecting member 21. The connecting member 21 is, for example, a bolt, which is inserted through the connecting portion 27 and fixed with a nut.

Further, the tip of the slip prevention member 25 is inserted between the support column 3 and the recess 23. The slip prevention member 25 is fixed to the female screw portion 29 (see FIG. 3) provided in the sandwiching portion 18. The details of the slip prevention member 25 will be described later.

Next, a method of reinforcing the antenna support column 3 using the reinforcing member 11 will be described. First, the reinforcing member 11 is attached to a predetermined portion of the support column 3. FIG. 4 is a plan view showing a state in which the reinforcing member 11 is attached to the support column 3. As described above, the support column 3 is sandwiched between the pair of sandwiching members 15, and the pair of sandwiching members 15 are connected by the connecting member 21. At this time, the tapered portion of the recess 23 described above comes into contact with the support column 3.

In the present embodiment, a pair of arm portions 17 are provided at predetermined angles at positions symmetrical with respect to the center line of each sandwiching member 15. That is, the wire rod fixing portion 19 is arranged at a position symmetrical with respect to the center line of the sandwiching member 15. Therefore, when the pair of sandwiching members 15 are opposed to each other and attached to the support column 3, the wire rod fixing portions 19 are arranged at a plurality of positions (4 locations in the figure) symmetrical with respect to the support column 3.

The wire rod fixing portions 19 may be arranged at at least three places, but when a pair of sandwiching members 15 having the same shape are used, the wire rod fixing portions 19 are arranged at even-numbered places (four places in the illustrated example). Will be done.

Here, a gap 31 is formed between the central portion of the recess 23 (parallel portion in the width direction between the tapered portions) and the support column 3. The gap 31 has a substantially trapezoidal shape in which the lower bottom has a curved shape corresponding to the outer surface shape of the support column 3.

Next, as shown in FIG. 5, in order to more reliably fix the reinforcing member 11 to the support column 3, the slip prevention member 25 is fixed. 6 (a) is a cross-sectional view taken along the line BB of FIG. 5, and FIG. 6 (b) is an enlarged view of part C of FIG. 6 (a). An insertion portion 33 projecting from a fixed surface with the sandwiching member 15 is provided at the tip of the slip prevention member 25. It is desirable that the insertion portion 33 has a wedge shape in which the thickness becomes thinner toward the tip.

The shape of the insertion portion 33 corresponds to the shape of the gap 31. That is, the contact portion with the support column 3 has a curved shape corresponding to the curved shape of the outer surface of the support column 3, and the other portion has a shape corresponding to the shape of the parallel portion in the width direction and the tapered portion of the recess 23.

With the insertion portion 33 of the slip prevention member 25 inserted into the gap 31, the insertion portion 33 is securely inserted into the gap 31 by tightening the slip prevention member 25 into the female screw portion 29 of the sandwiching portion 18 with a bolt 32. To. At this time, as the insertion portion 33 is deeply inserted into the gap 31, the thickness of the insertion portion 33 inserted into the gap increases. Therefore, by pushing the insertion portion 33 deeply into the gap 31, the insertion portion 33 pushes the gap 31 open, and the support column 3 is strongly pressed against the sandwiching member 15 (displacement prevention member 25). Instead of providing the female screw portion 29 on the sandwiching member 15, the sandwiching member 15 may be fixed with a bolt 32 and a nut.

By using the slip-preventing member 25 in this way, the sandwiching member 15 is securely fixed to the support column 3, and the reinforcing member 11 is prevented from slipping. If the reinforcing member 11 can be fixed to the support column 3 without using the slip-preventing member 25, the slip-preventing member 25 is not always necessary.

After fixing the reinforcing member 11 above and below the support column 3, the reinforcing wire 13 is fixed to each of the wire fixing portions 19 of the upper and lower reinforcing members 11. At this time, some tension is applied to the reinforcing wire rod 13. As described above, the antenna support reinforcing structure 1 can be constructed.

As described above, according to the present embodiment, the support column 3 of the antenna can be reinforced by a simple method. Further, by using the slip prevention member 25, the reinforcing member 11 can be reliably fixed to the support column 3.

Further, since the wire rod fixing portion 19 is arranged at the tip of the arm portion 17, the wire rod fixing portion 19 can be arranged at a position away from the support column 3. Therefore, the support column 3 can be efficiently reinforced. Further, as the sandwiching member 15, a pair of members having the same shape can be used. Therefore, the wire rod fixing portion 19 can be arranged at symmetrical positions with the support column 3 as the center. Therefore, the support column 3 can be efficiently reinforced.

The reinforcing member 11 according to the present invention can be applied to different column sizes. FIG. 7 is a plan view showing a state in which the reinforcing member 11 is fixed to the support column 3a having a larger diameter. Even in this case, the support column 3a can be brought into contact with the recess 23, and the support column 3a can be sandwiched and fixed by the pair of sandwiching members 15.

In this case, the shape of the gap 31 between the support column 3a and the recess 23 is different from that of the support column 3. Therefore, a slip prevention member 25a corresponding to the shape of the gap 31 is used. That is, the same sandwiching member 15 can be applied to different strut sizes by changing only the slip prevention member according to the strut size.

When the thick support column 3a is sandwiched between the sandwiching members 15, the spacer 37 is attached between the connecting portions 27 facing each other. The spacer 37 is a tubular member, and the connecting member 21 is inserted therein. Since the outer diameter of the spacer 37 is larger than the inner diameter of the connecting portion 27, the spacer 37 maintains the distance between the connecting portions 27. Therefore, when the connecting member 21 is tightened, the rotation of the sandwiching member 15 is suppressed, and the sandwiching members 15 can be surely opposed to each other in a straight line.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the technical scope of the present invention does not depend on the above-described embodiments. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the technical ideas described in the claims, and these are naturally included in the technical scope of the present invention. It is understood that it belongs.
