On the other hand, the tip of the hooking portion 22 is located at a position shifted from the center of the reinforcing member main body 20 to the other side in the lateral width direction. Therefore, the hook portion 22 extends from one side to the other side of the reinforcing member main body portion 20 in the lateral width direction.

  As shown in FIG. 3, the lower end of the hooking portion 22 (the end on the side of the reinforcing member main body 20) extends along the width direction of the reinforcing member main body 20 and is placed on the shaft member 511. The mounting section 220 is possible. Further, the mounting portion 220 is configured to be mounted on the shaft member 511 in a state where the pair of reinforcing members 2 have been rearranged from the first position to the second position. Therefore, by placing the mounting portion 220 on the shaft member 511, the reinforcing member 2 inserted into the support column 50 can be hung on the shaft member 511.

  The spacers 3 are configured to abut on the respective inner facing surfaces 20 b of the pair of reinforcing members 2 in a state inserted between the pair of reinforcing members 2. The spacer 3 may be configured to abut on the respective inner facing surfaces 20b of the pair of reinforcing members 2 when inserted between the pair of reinforcing members 2 (see FIG. 8), or (For example, when an external impact is applied to the column 50), and may be configured to come into contact with the respective inner facing surfaces 20 b of the pair of reinforcing members 2. .

  As shown in FIG. 5, the spacer 3 according to the present embodiment includes a pair of long plate portions 30 that are long and are opposed to each other in a parallel posture with an interval therebetween. And a connecting portion 31 connected to each of the plate portions 30.

  The pair of long plate portions 30 have a rectangular shape and are arranged with the plate surfaces facing each other. In addition, the continuous portion 31 also has a rectangular shape, and each long side of the pair of long plate portions 30, more specifically, one long plate opposed in the direction in which the pair of long plate portions 30 are arranged. The long side of the portion 30 and the long side of the other long plate portion 30 are continuous. Therefore, the spacer 3 of the present embodiment has a U shape.

  When the spacer 3 is inserted between the pair of reinforcing members 2, one outer surface of the pair of long plate portions 30 is disposed to face the inner facing surface 20 b of the one reinforcing member 2, and the other long plate portion 30 is long. The outer surface of the plate portion 30 is disposed to face the inner facing surface 20b of the other reinforcing member 2.

  As shown in FIG. 4, the guide structure 4 includes an insertion guide portion 40 that guides the spacer 3 inserted between the pair of reinforcing members 2 in the height direction, and the spacer 3 between the pair of reinforcing members 2. A positioning unit 41 for determining an insertion position (the position in the height direction).

  The insertion guide part 40 of the present embodiment is configured by a convex part protruding from the inner facing surface 20b.

  In addition, a group of a plurality of insertion guides 40 formed in a row along the axial direction of the reinforcing member main body 20 is provided on one side of the inner facing surface 20b in the horizontal width direction (the horizontal width direction of the reinforcing member main body 20). The insertion guide portions 40 are formed in two rows, and a plurality of insertion guide portions 40 are also provided on the other side of the inner facing surface 20b in the lateral width direction (the lateral width direction of the reinforcing member main body portion 20). A group of insertion guide portions 40 arranged in a line along the axial direction is formed in two lines.

  Two groups of insertion guide portions 40 formed on one side in the width direction of the inner facing surface 20b are arranged in the width direction at an interval wider than the width of the long plate portion 30. Also, two groups of insertion guide portions 40 formed on the other side in the lateral width direction are arranged in the lateral direction at an interval wider than the lateral width of the long plate portion 30.

  The positioning portion 41 is provided so as to protrude from the inner facing surface 20b, and is formed on the front side (the front side in the insertion direction) of the insertion guide portion 40. Therefore, when the spacer 3 is inserted between the insertion guide portions 40 with the long plate portion 30 along the inner facing surface 20b, the tip of the spacer 3 abuts on the positioning portion 41, and the reinforcing member 2 The position of the spacer 3 between them is determined.

  The configuration of the column reinforcement 1 according to the present embodiment is as described above. Subsequently, a method for reinforcing a column for a fence structure using the column reinforcing tool 1 according to the present embodiment will be described.

  In the column reinforcement method, a pair of reinforcement members 2 are inserted into the column 50 between the shaft member 511 and the inner surface of the column 50 (see FIG. 6).

  One of the reinforcing members 2 is arranged such that the outer facing surface 20a faces the inner surface of the column 50, and then the reinforcing member main body 20 is inserted into the column 50 through one insertion region. I do. Also, the other reinforcing member 2 adjusts the direction of the reinforcing member main body 20 so that the outer facing surface 20a faces the inner surface of the support 50, and then connects the reinforcing member main body 20 to the support 50 through the other insertion region. Insert

  Thereby, the pair of reinforcing member main bodies 20 arranged below the shaft member 511 in the support column 50 are arranged side by side (the sideways in the lateral direction) with the inner facing surfaces 20b facing each other. .

  In the present embodiment, it is sufficient to change the direction and the posture of the reinforcing member main body portion 20 by holding the extension operation portion 21 or perform the operation of inserting the reinforcing member main body portion 20 into the support column 50.

  Subsequently, the pair of reinforcing members 2 are arranged in the axial direction of the support column 50 and in the first position in which the reinforcing members 2 are arranged at an interval between each other in a lateral direction orthogonal to the insertion direction of the shaft member 511, The arrangement is changed to a second position arranged at intervals in the insertion direction (see FIG. 7). In this way, a space between the pair of reinforcing members 2 (that is, an insertion space into which the spacer 3 can be inserted) is formed on both sides of the shaft member 511 in a state where the support 50 is viewed in a plan view.

  Then, a pair of spacers 3 is inserted into the insertion space (see FIG. 8). At this time, one spacer 3 is inserted into the insertion space through one insertion region, and the other spacer 3 is inserted into the insertion space through the other insertion region.

  In addition, the spacer 3 inserted into the insertion space is guided by the insertion guide portion 40 and is inserted straight along the height direction, and the distal end abuts on the positioning portion 41, whereby the pair of reinforcing members 2 The insertion depth (position in the height direction) of the spacer 3 into the space between them is determined.

  In this manner, after the pair of reinforcing members 2 are inserted into the column 50 through the space between the shaft member 511 and the inner surface of the column 50, the pair of reinforcing members 2 are inserted into the column 50 of the fence structure 5. From a first position spaced apart from each other in a lateral direction orthogonal to each of the axial direction of the support 50 and the insertion direction of the shaft member 511, a first position spaced apart from each other in the insertion direction. A reinforcement structure is constructed in which the arrangement is changed to the second position, and the spacer 3 is inserted between the pair of reinforcement members 2 whose arrangement is changed to the second position, between the shaft member 511 and the inner surface of the column 50.

  Further, the reinforcing structure is inserted into the support column 50 such that the pair of reinforcing member main bodies 20 straddle vertically above and below the ground with the outer facing surface 20a abutting on the inner peripheral surface of the support column 50, and Since the spacer 3 is inserted between the pair of reinforcing member main bodies 20, the strength against breakage of the base of the column 50 can be increased.

  As described above, according to the column reinforcement 1 according to the present embodiment, when the pair of reinforcement members 2 are inserted into the column 50 from between the inner peripheral surface of the column 50 and the shaft member 511, the pair of reinforcement members 2 Is formed at a position overlapping with the shaft member 511 in a plan view, but the pair of reinforcing members 2 inserted into the column 50 from between the shaft member 511 and the inner surface of the column 50 are moved from the first position to the second position. The space can be formed at a position deviated from the shaft member 511 in a plan view by changing the arrangement of the pair of reinforcing members 2 from the first position to the second position. .

  When the spacer 3 is inserted into the space through the space between the shaft member 511 and the inner surface of the column 50, the spacer 3 keeps the space between the pair of reinforcing members 2 to reinforce the column 50.

  As described above, the support structure 1 for a fence structure can reinforce the support column 50 with the shaft member 511 fixing the beam 52 to the support column 50 attached to the support column 50 and the beam 52. An excellent effect that the structural column 50 can be reinforced can be obtained. Further, also in the column reinforcement structure and the column reinforcement method, similarly to the column reinforcement 1, there can be provided an excellent effect that the column 50 for the fence structure can be reinforced by a simple operation.

  In addition, since the reinforcing member 2 is provided with the extending operation unit 21 that extends rearward in the direction in which the reinforcing member 2 is inserted into the support column 50, the worker can use the extending operation unit 21. The reinforcement member 2 can be inserted into the support column 50 while holding the gripping member, and the arrangement of the reinforcement member 2 in the support column 50 can be changed from the first position to the second position. Will be able to do it.

  Further, the extension operating portion 21 is provided with a hooking portion 22 that is hooked on the shaft member 511 in a state where the pair of reinforcing members 2 are rearranged from the first position to the second position. Therefore, by locking the locking portion 22 on the shaft member 511 in a state where the pair of reinforcing members 2 are switched from the first position to the second position, the spacer 3 is positioned between the pair of reinforcing members 2. Can be easily maintained.

  In addition, since the guide structure 4 has the insertion guide portion 40 that guides the spacer 3 between the pair of reinforcing members 2 in the axial direction of the column 50, the spacer 3 is moved along the axial direction between the pair of reinforcing members 2. Easier to move. Therefore, the strength of the post 50 after reinforcement can be easily adjusted by facilitating the insertion of the spacer 3 between the pair of reinforcement members 2 in a straight posture along the axial direction. It becomes easy to adjust the strength of 50 to the desired strength.

It may be configured.

  In the above embodiment, the position of the pair of reinforcing members 2 arranged in the insertion direction has been described as the second position, but the present invention is not limited to this configuration. For example, in the above embodiment, a direction inclined with respect to the insertion direction and the lateral direction may be the second position of the pair of reinforcing members 2.

  In the above-described embodiment, the pair of reinforcing members 2 are configured as separate objects. However, for example, the extending operation sections 21 and the hooking sections 22 may be connected to form an integrated body.

  In the above-described embodiment, the reinforcing member main body portion 20 is configured to have the hollow columnar (more specifically, polygonal cylindrical) cylindrical portion 200, but is not limited to this configuration. For example, as shown in FIGS. 11 to 15, the reinforcing member main body 20 may be configured to have a curved or bent plate-like portion 202. Further, in the reinforcing member 2 shown in FIG. 11, the tip of the hooking portion 22 hangs downward, and the insertion guide portion 40 is formed in a groove shape.

  In the reinforcing member main body 20 shown in FIGS. 11 to 15, one outer surface (outer peripheral surface) of the plate-like portion 202 becomes an outer facing surface 20 a arranged to face the inner surface of the support 50, and (Inner peripheral surface) is an inner facing surface 20b arranged toward the reinforcing member body 20 of the other reinforcing member 2.

  In the above embodiment, the pair of long plate portions 30 are arranged with the plate surfaces facing each other, but the present invention is not limited to this configuration. For example, as shown in FIG. 12, the pair of long plate portions 30 may be arranged side by side with their width directions aligned in the same direction. In this case, the connecting portion 31 may be bent or curved in a direction orthogonal to the direction in which the pair of long plate portions 30 are arranged.
