Description

  The present invention relates to a fixture that can be mounted on a columnar body having a circular cross-sectional outer shape such as a steel pipe.

  Many structures, such as steel pipe towers, utility poles, signal poles, etc., are composed of columnar bodies having a circular cross-sectional outer shape, and these structures are each equipped with fixtures or the like according to the application. In the case of installation of fixtures, etc. that are planned from the beginning of construction of steel pipe towers etc., it is easy to process the steel pipes etc. on the side where the columns are mounted before operation of the steel towers, etc. A variety of attachment methods have been developed and adopted without receiving them. For example, as shown in FIG. 2 (1), when the locking bolt 12 is passed through the through hole 11 provided in the utility pole 10, the brace 14 is mounted on the utility pole 10 using the U-shaped band 13. Is described in Patent Document 1.

  On the other hand, it is also applicable to cases where fixtures etc. need to be attached after construction of steel pipe towers, etc., or where fixtures etc. are required to be firmly attached to a predetermined location without changing the structure of the structure. As described above, there is no need to process a steel pipe or the like on the side where the column is mounted, and a column method that takes into account the restriction of the outer shape of the steel pipe or the like has been developed and adopted. For example, as shown in FIGS. 2- (2) and 2- (3), Patent Literature 2 describes a fixing bracket that fixes a pipe 15 to a support member 18 using a U bolt 16 and an adjustment member 17. . In this case, it is not particularly necessary to process the pipe 15 side which is a columnar body in order to mount the column.

  Moreover, in patent document 2, although the U volt | bolt 16 is used with respect to the U-shaped band 13 of patent document 1, in appearance, it is similar to the case where the penetration bolt 12 is not used in patent document 1. In addition, in the case of the fixing bracket shown in FIGS. 2- (2) and 2- (3), since the angle member is used for the support member 17, the cross-section efficiency is good, and the nut 4 is tightened without fear of deformation of the support member 17. It is possible to tighten to.

  Further, as shown in FIGS. 2 (4) and 2 (5), Patent Literature 2 also describes a fixing bracket in which a V block 19 cut out in a V shape is attached to the support member 18 side. If the support member 18 side is V-shaped, the number of contact points between the support member 18 side and the pipe 15 can be increased to two, and the fixation can be further strengthened.

  However, when the U bolt 16 is used in this way, if there is a difference in the outer shape of the pipe 15 and the U-curvature of the U bolt 16, there is one contact between the pipe 15 and the U bolt 16, so that the contact as a fixing bracket And may become unstable when the position is firmly fixed. In the case of the U-shaped band 13, since the band can be deformed according to the outer shape of the utility pole 10, a sufficient contact with the utility pole 10 can be secured. However, the U-shaped band 13 is disadvantageous in terms of strength compared to the U bolt 16 because the band thickness needs to be reduced so that the U-shaped band 13 can be deformed.

  Furthermore, as shown in FIG. 5- (1), there is also known a fixing bracket in which a V bolt 3 and a steel plate 5 are combined. If such a V bolt 3 is used, two contact points with the cylinder 2 are reliably secured. It can be fixed with three contacts together with the steel plate 5. The shape of this V bolt is from a U-shaped bolt consisting of a curved joint between two parallel straight sides of the U bolt 16 shown in FIGS. It is a V-shaped bolt in which only the coupling portion is changed to a linear corner without changing the portion. In addition, the columnar body to be mounted is a cylinder because a circular cross-sectional outer shape is a main problem.

  Here, when fixing the above-mentioned known fixing bracket to the cylinder, the contact points between the fixing bracket and the cylinder are summarized as follows: (A) In the case of the fixing bracket using the U-shaped band 13 in FIG. Although there are subtle points, the steel fittings in Fig. 2- (2) and (3) have a single point of contact with the cylinder (pipe 15) in the case of the U bolt 16, so In combination with the (adjusting member 17), the column (pipe 15) and the two contact points, (U) the fixing brackets of FIGS. 2- (4) and (5) use the V block 19 for the steel plate. Since the number of contacts on the steel plate side is increased to two, in combination with the U bolt 16, the cylinder (pipe 15) and the three contacts, (e) the fixing bracket of FIG. Since there are two contacts with 2, the cylinder 2 and the three contacts are fixed together with the steel plate 5.

  As described above, the above-mentioned known fixing brackets are fixed to the cylinder with three or less contacts except for (a). By the way, since it is thought that the one where there are many contact points between the fixing bracket and the cylinder can suppress the rotation of the fixing bracket around the cylinder and can be firmly fixed, consider a fixing bracket having more contact points with the cylinder.

  For example, as shown in FIG. 5- (2), a V block 19 having a V-block 19 cut into a V-shape on the side of the steel plate 5 such as the support member 18 of FIGS. 2- (4) and (5) is attached. It is also conceivable to increase the number of contacts with the column 2 on the steel plate 5 side to two using the block-attached steel plate. Similarly, as a method of making the steel plate 5 side V-shaped, as shown in FIG. 5- (3), a method of using a V-shaped bent steel plate in which the steel plate 5 is bent into at least three places to form a V shape, or FIG. As shown in 4), a method is conceivable in which an angle material 8 is used for the steel plate 5 and a V-shaped notched angle material in which a V-shaped notch 20 is provided on one side. Such a fixture can be fixed to the cylinder 2 by four contact points.

  However, when using the V-block attached steel plate of Fig. 5- (2) or using the V-shaped notched angle material of Fig. 5- (4), the tightening position of the V bolt 3 and nut 4 on the steel plate 5 side. And the positional relationship between the V-shape on the steel plate 5 side and the contact point of the cylinder 2, there is a possibility that the direction of the force applied when the nut 4 is tightened and the force to be fixed to the cylinder 2 may be shifted. There is. Moreover, when using the V-shaped bending steel plate of FIG. 5- (3), the bending process of the steel plate 5 becomes a little complicated.

  Furthermore, as shown in FIG. 5- (5), the steel plate 5 side is bent at least once to form a V shape, and the V-shaped bent steel plate having a shape different from that of FIG. A method of using a V bolt having a shape different from that shown in FIGS. The shape of this V bolt is different from the U and V bolts described above, and the sides of the U shape and the V shape are not parallel. In this case, there is an advantage that both the V-bolt 3 side and the steel plate 5 side can be formed only once at least once. Such a fixture can also be fixed to the cylinder 2 by four contact points.

  In addition, there is also known a fixing metal fitting in which metal parts that are divided in the circumferential direction in order to be mounted on a power pole are coupled with bolts and nuts. For example, Patent Literature 3 describes a fixing bracket in which a band body divided into three in the circumferential direction is disposed on the outer periphery of a utility pole, and the band bodies are fastened with bolts and nuts to be closely fixed to the utility pole. Patent Document 4 describes a fixing bracket in which a divided body that is divided into four in the circumferential direction is arranged on the outer periphery of a utility pole, and the divided bodies are fastened with bolts and nuts to be closely fixed to the utility pole.

  These fixing brackets are divided into three triangles with respect to the outer circumference of the utility poles, etc., and arranged in a square arrangement with four divisions, so that the fixtures are fixed on the utility poles. By increasing the number of pieces, it is possible to increase the number of contacts with the utility pole (cylinder) of the fixing bracket, so that it can be fixed more firmly. However, as the number of pieces of the split bracket increases, the manufacture of the fixing bracket and the mounting column of the fixing bracket are troublesome. become.

  The fixing bracket as shown in FIG. 5 (5) is advantageous because it can secure a column and four contact points, has fewer pieces of the bracket, and requires fewer steps to manufacture the bracket. However, when the fixing bracket is mounted on the column 2, it can be fixed. However, when the nut 4 is tightened to fix it more firmly, the steel plate 5 side is relatively weak, and the bolt hole 7 on the steel plate 5 side. Is a long hole 22, and the nut 4 is further tightened depending on the pressure applied to the nut 4. Accordingly, when fixing with a predetermined strength, it becomes difficult to ensure the quality of the fixed state, so workability is very poor.

  The shape of the V bolt is different from the shapes of the U bolt and other V bolts, and the sides of the U shape and the V shape are not parallel. In the case of this fixing metal structure, the V-shaped side of the V-bolt is not parallel, so the V-bolt 3 cannot be assembled to the steel plate 5 unless the bolt hole 7 is the long hole 22. Also, in order to improve the cross-sectional efficiency of the steel plate 5, it is difficult to use an angle material as the steel plate 5 because it is very difficult to bend the angle material. In addition, if a thick steel plate is used, part of the problem can be improved. However, the thick plate is difficult to bend, and there is a problem that the fixture is excessively heavy.

  Also, if the fixture is made up of multiple pieces as described above, it will be possible to easily increase the number of contacts with the cylinder, but the manufacturing may be complicated and the mounting work may be difficult. I don't want to increase too many pieces.

  The present invention solves such problems, has a simple structure, has many contact points with a cylinder, is easy to manufacture, is not excessively heavy, and can be mounted on a columnar body having a circular cross section such as a steel pipe. It is a metal fitting.

  According to a first aspect of the present invention, there is provided a V-shaped V-bolt comprising two sides having mutually non-parallel screw portions, a connecting portion of the two sides, and a fastening nut screwed into each of the screw portions of the V-bolt, A bolt hole through which the threaded portion of the V-bolt is inserted is provided in the flange, and two angle members provided with bolt holes for connecting to the other flange are inserted into the bolt hole for connection.

A fixing bracket made of an adjusting nut, wherein the columnar body is mounted so as to be surrounded by a square with the two sides of the V bolt, the channel material, and the angle member. Fixing bracket).

  In a fourth aspect of the present invention, a connection pin is used instead of the adjustment bolt and the adjustment nut screwed to the adjustment bolt, and a pin hole is provided for connection instead of the bolt hole for connection. It is a fixing metal fitting (fourth fixing metal fitting) as described in any one of thru | or 3rd invention.

  The fixing bracket of the present invention can be firmly mounted on a predetermined portion of a columnar body having a circular cross-sectional outer shape such as a steel pipe without particularly processing the steel pipe or the like.

  In addition, the fixing bracket of the present invention has a small number of parts, is easy to manufacture, is relatively lightweight, and is easy to install.

  The present invention is a fixing bracket comprising a fastening nut that is screwed with a V bolt, and two steel plates that are connected by an adjusting nut or a connecting pin that is screwed with an adjusting bolt. Material or channel material is used. The fixing bracket of the present invention surrounds a columnar body having a circular cross-sectional outer shape in a quadrangular shape with two sides of these V bolts and two steel plates, and secures at least four points of contact with the circular cross-sectional outer shape. It is possible to firmly mount the pillar at a predetermined position of the columnar body.

  FIG. 1 is an explanatory view showing a state in which the first fixing metal fitting of the present invention is mounted on a cylinder. As described above, the first fixture 1 of the present invention includes the V bolt 3, the fastening nut 4 a that is screwed into each of the screw portions 21 provided on the V bolt 3, the adjustment bolt 6, and the adjustment bolt 6. It consists of a steel plate 5 made of two angle members 8 connected by an adjusting nut 4b to be joined, and surrounds the cylinder 2 so as to form a quadrangle with the two sides of the V bolt 3 and the two angle members 8. It is done. Therefore, the four sides of the quadrangle formed by the two sides of the V bolt 3 and the two angle members 8 are in contact with the cylinder 2 and can be firmly mounted on the cylinder 2 with the four contacts.

  As shown in FIG. 1, the V-bolt 3 of the present invention uses a V-shaped V-bolt having two and two side coupling portions and two sides provided with screw portions being non-parallel. Referring to FIG. 5, the V bolt 3 shown in FIG. 5-(5) has the shape of the V bolt of the present invention, but the V bolt 3 shown in FIGS. 5 (1) to (4) has a screw portion 21. This is not a V-bolt according to the present invention.

  Although FIG. 1 shows an example in which the V bolt opens at two sides of 90 degrees, this opening is not particularly limited to 90 degrees. However, the V bolts of the present invention must be non-parallel on the two sides provided with the screw parts, including those described later. If the screw portion 21 is parallel, a rectangular shape is formed by the two sides of the V bolt 3 and the two steel plates 5 so as to surround the cylinder 2, and a simple steel plate can be used. It is impossible to be there. In addition, as shown in FIGS. 5- (1) to (4) as compared with FIG. 5- (5), when the screw portions are parallel, a plurality of bending processes are performed on the steel bar to form a V bolt. Is required.

  Further, the steel plate 5 of the first fixing bracket 1 is made of an angle member 8, and a bolt hole 7 for inserting the screw portion 21 of the V bolt 3 is provided on one side of the angle member 8. A bolt hole 7 for inserting an adjusting bolt 6 for connection is provided in the flange. Moreover, since it becomes an obstacle when the angle members 8 are connected to each other, at least one of the angle members overlaps with one of the ridges.

  Further, when the angle member 8 is used for the steel plate 5, it is necessary to mount the pole so that the flange of the angle member 8 is in contact with the column 2 as shown in FIG. If the pole is mounted so that the tip of the flange of the angle member 8 is in contact with the cylinder 2, the direction of the force applied when the fastening nut 4 a is tightened and the direction of the force when contacting the cylinder 2 are shifted, and there is a possibility that it cannot be firmly fixed.

  As shown in FIG. 1, in the case of the V bolt 3 having an opening of 90 degrees, it is desirable to use a fixing bracket having a size such that the quadrangle surrounding the column 2 is close to a square in accordance with the size of the column 2. Here, when the dimension of the cylinder 2 is small, the distance between the fastening nuts 4a is reduced by adjusting the fastening nut 4a so that the angle between the angle members 8 connected by the adjusting bolt 6 is reduced, that is, Match the dimensions of the cylinder 2 so that the dimension of the diagonal of the quadrangle is shortened. If the dimension of the cylinder 2 is large, the angle between the angle members 8 connected by the adjustment bolt 6 is increased. By adjusting the nut 4a to increase the distance between the fastening nuts 4a, that is, the length of the diagonal of the quadrangular shape can be increased to match the size of the column 2, the fixing bracket of the present invention is provided with the column 2 It is possible to cope with minor dimensional differences.

  Moreover, when the 1st fixing metal fitting 1 shown in FIG. 1 is fixed to the cylinder 2, the two angle members 8 do not necessarily need to be firmly fastened by the adjustment bolt 6 and the adjustment nut 4b. It is sufficient if the adjustment bolt 6 and the adjustment nut 4b are removed and the angle member 8 is not disconnected. However, when assembling the fixing bracket, in the state in which the two angle members 8 are connected, it is difficult to assemble the V bolt 3 unless the bolt hole 7 for the V bolt is a long hole. Therefore, the angle member 8 can be separated. Such adjustment bolt 6 and adjustment nut 4b are better. If separable, the bolt hole 7 can be adjusted to a normal bolt diameter.

  As an example of the fourth fixing metal fitting of the present invention, the adjustment bolt 6 and the adjustment nut 4b of FIG. 1 are changed to a connecting pin, and the bolt hole 7 for the adjusting bolt 6 is changed to a pin hole for the connecting pin. To do. As described above, the two angle members 8 do not need to be firmly fastened, and the two angle members 8 are connected, and the angle between the angle members 8 is fixed when the V bolt 3 and the fastening nut 4a are fixed. Since it only needs to be adjustable, a connecting pin and a pin hole can be used as the fixing bracket of the present invention. However, it is better to use a connecting pin and a pin hole so that the two angle members 8 can be separated when assembling and mounting the fixing bracket due to a request similar to the above.

  FIG. 3 is an explanatory view showing a state in which the second fixing metal fitting of the present invention is mounted on a cylinder. As described above, the second fixing bracket 1 of the present invention includes the V bolt 3, the fastening nut 4 a that is screwed into each of the screw portions 21 provided on the V bolt 3, the adjustment bolt 6, and the adjustment bolt 6. The cylinder 2 is formed by two steel plates 5 of the channel material 9 connected by the adjusting nut 4b to be joined, and the square 2 is formed by the two sides of the V bolt 3 and the steel plate 5 made of the two channel materials 9. Mounted enclosed. Therefore, the four sides of the quadrangle formed by the two sides of the V bolt 3 and the two channel members 9 are in contact with the cylinder 2 and can be firmly mounted on the cylinder 2 with the four contacts.

  Here, the V bolt 3 to be used is substantially the same as that in FIG. 1, and the V bolt 3 has an example in which two sides open at 90 degrees, but this opening is not particularly limited to 90 degrees.

  The steel plate 5 is made of a channel material 9, and a bolt hole 7 for inserting the threaded portion 21 of the V bolt 3 is provided at the groove bottom of the channel material 9. Bolt holes 7 for inserting 6 are provided. The bolt hole 7 may not be a long hole as in the case of the first fixing bracket using the angle member 8. In addition, it is desirable to cut out at least one of the channel material ridges or the overlapping part of the groove bottom so as not to obstruct the connection between the channels 9.

  Further, in the case of the second fixing bracket 1 using the channel material 9 for the steel plate 5, if the column bottom is mounted so that the groove bottom of the channel material 9 is in contact with the cylinder 2, the operation of the fastening nut 4 a is performed in the channel 9. In view of the operability of the fastening nut 4a, it is desirable to mount the fixing bracket so that the tip of the flange of the channel member 9 is in contact with the cylinder 2 as shown in FIG. However, in the case of the channel member 9, unlike the case of the angle member 8, there is no possibility that the direction of the force applied when the fastening nut 4 a is tightened and the force contacting the cylinder 2 are not shifted in any of the mounting column methods.

  In the case of the second fixing bracket, similarly to the first fixing bracket, in the case of the V bolt 3 having an opening of 90 degrees, the quadrangle surrounding the cylinder 2 is close to a square according to the dimension of the cylinder 2. It is desirable to use a fixture with a proper size. Similarly, the angle between the channel members 9 connected by the adjusting bolt 6 and the position of the fastening nut 4a on the V-bolt 3 are adjusted to adjust the distance between the fastening nuts 4a, that is, the size of the diagonal of the quadrangle. Since it can be adjusted to the dimension of the cylinder 2, the second fixing bracket of the present invention can cope with a slight dimensional difference from the cylinder 2.

  Similarly, when the second fixture 1 shown in FIG. 3 is fixed to the cylinder 2, the two channel members 9 do not necessarily have to be firmly fastened by the adjustment bolt 6 and the adjustment nut 4b. It is sufficient if the adjustment bolt 6 and the adjustment nut 4b are removed and the connection of the channel material 9 is not released. However, when assembling the fixing bracket, when the two channel members 8 are connected, it is difficult to assemble the V bolt 3 unless the bolt hole 7 is a long hole. The bolt 6 and the adjusting nut 4b are better.

  FIG. 4 is an explanatory view showing a state in which another first fixing metal fitting of the present invention is mounted on a cylinder. The first fixing bracket 1 of the present invention of this example is also screwed into the V bolt 3, the fastening nut 4 a that is screwed into each of the screw portions 21 provided on the V bolt 3, the adjustment bolt 6, and the adjustment bolt 6. The steel plate 5 is composed of two angle members 8 connected by an adjusting nut 4b. The two sides of the V bolt 3 and the two angle members 8 surround the cylinder 2 so as to form a quadrangle. Therefore, the four sides of the quadrangle formed by the two sides of the V bolt 3 and the two angle members 8 come into contact with the column 2 and can be firmly mounted on the column 2 with the four contacts.

  Further, as shown in FIG. 4, the steel plate 5 is made of an angle member 8, and a bolt hole 7 for inserting the screw portion 21 of the V bolt 3 is provided on one side of the angle member 8. A bolt hole 7 for inserting an adjusting bolt 6 for connection is provided in the flange. Moreover, since it becomes an obstacle when the angle members 8 are connected to each other, at least one of the angle members overlaps with one of the ridges.

  Also, in the case of the first fixing bracket using the angle member 8, it is necessary to mount the pole so that the hook of the angle member 8 is in contact with the column 2 as shown in FIG. If the pole is mounted so that the tip of the flange of the angle member 8 is in contact with the cylinder 2, the direction of the force applied when the fastening nut 4 a is tightened and the direction of the force fixed to the cylinder 2 are shifted, and there is a possibility that it cannot be firmly fixed.

  As shown in FIG. 4, the V bolt 3 of the present invention also uses a V-shaped V bolt having two sides and a two-side coupling portion and two sides provided with screw portions being non-parallel. The example of the first fixing metal fitting shown in FIG. 4 is different in that the opening angle of the V bolt 3 used is 75 degrees, whereas the opening angle of the V bolt 3 used in FIG. 1 is 90 degrees. Other configurations are the same.

  Moreover, although the opening of 2 sides of the V bolt 3 is 75 degrees in FIG. 4, 90 degrees in FIG. 1, and 90 degrees in FIG. 3, this opening is not limited to these examples. However, for the reasons described above, the V bolts used in the present invention must be non-parallel on the two sides where the screw portions are provided.

  As shown in FIG. 4, in the case of the V bolt 3 having an opening of 75 degrees and in the case of using the V bolt 3 having a different opening, the two sides of the V bolt 3 surrounding the cylinder 2 are matched to the dimensions of the cylinder 2 and Fixing dimensions such that a quadrangular shape made of two steel plates 5 (angle members 8) is a saddle shape and the angle between one side of the V bolt 3 and the steel plate 5 (angle member 8) to be fastened is close to a right angle. It is desirable to use metal fittings. Also here, when the dimension of the cylinder 2 is small, the distance between the fastening nuts 4a is reduced by adjusting the fastening nut 4a so that the angle between the angle members 8 connected by the adjusting bolt 6 is reduced, that is, Match the dimensions of the cylinder 2 so that the dimension of the diagonal of the quadrangle is shortened. If the dimension of the cylinder 2 is large, the angle between the angle members 8 connected by the adjustment bolt 6 is increased. By adjusting the nut 4a to increase the distance between the fastening nuts 4a, that is, the length of the diagonal of the quadrangular shape can be increased to match the size of the column 2, the fixing bracket of the present invention is provided with the column 2 It is possible to cope with minor dimensional differences.

  Even the second fixing bracket using the channel material 9 as the steel plate 5 of the present invention can be configured by using a V bolt 3 having an opening of 75 degrees as shown in FIG. In this case as well, the two channel members are dimensioned so that the quadrangular shape composed of the two sides of the V bolt 3 surrounding the cylinder 2 and the two steel plates 5 (channel members 9) becomes a saddle shape as shown in FIG. What is necessary is just to adjust the angle between the steel plates 5 made of 9, and to mount the columns.

  Next, the third fixing bracket of the present invention uses the angle bolt 8 on one side and the channel material 9 on the other side as the V bolt and the two steel plates of the present invention described above. From the description of examples of the first fixing bracket and the second fixing bracket using the angle member 8 and the channel member 9 as the two steel plates 5, respectively, in FIG. 1, FIG. 3, and FIG. It can be seen that 5 can be replaced with the angle member 8 or the channel member 9.

  The angle member 8 used for the one steel plate 5 is provided with a bolt hole 7 for inserting the screw portion 21 of the V bolt 3 in one of the flanges of the angle member 8 and for connecting to the other flange. A bolt hole 7 for inserting the adjusting bolt 6 is provided. In addition, when attaching the fixing bracket, it is better to mount the pole of the angle member 8 so as to contact the cylinder 2 as shown in FIGS. 1 and 4, so that the tip of the hook of the angle member 8 contacts the cylinder 2. Don't be a pillar. If the pole is mounted so that the end of the flange of the angle member 8 is in contact with the cylinder 2, the direction of the force applied when the fastening nut 4a is tightened and the direction of the force fixed to the cylinder 2 are shifted, and there is a possibility that it cannot be firmly fixed. However, when channel material is used for the other steel plate, this fear is alleviated.

  Further, a bolt hole 7 for inserting the threaded portion 21 of the V bolt 3 is provided at the groove bottom of the channel material 9 used for the other steel plate 5, and an adjusting bolt 6 for connection is inserted into the flange. Bolt holes 7 are provided. In addition, when attaching the fixing bracket, it is desirable to mount the fixing bracket so that the groove bottom of the channel member 9 is in contact with the cylinder 2 or the tip of the flange of the channel member 9 is in contact with the cylinder 2. Although there is a difference in the operability of the fastening nut 4a depending on the mounting method, unlike the case of the angle member 8, the direction of the force applied when the fastening nut 4a is tightened and the force of contacting and fixing the cylinder 2 with either mounting method. There is no risk of slipping.

  Further, it is desirable to cut out at least one of the portions where the ridges of the angle member 8 overlap the ridges and the groove bottoms of the channel member 9 so as not to obstruct the connection between the angle member 8 and the channel member 9.

  Further, even when the first fixing bracket, the second fixing bracket, and the third fixing bracket are fixed to the cylinder 2, the two steel plates 5 (the angle member 8, the channel) are not necessarily provided by the adjusting bolt 6 and the adjusting nut 4b. The material 9) does not need to be firmly fastened, and it is sufficient that the adjusting bolt 6 and the adjusting nut 4b are not detached and the connection between the two steel plates 5 (the angle material 8 and the channel material 9) is not released. However, when assembling the fixing bracket, it is difficult to assemble the V bolt 3 in a state where the two steel plates 5 (the angle member 8 and the channel member 9) are connected, so the two steel plates 5 (the angle member 8, It is better to use the adjusting bolt 6 and the adjusting nut 4b so that the channel material 9) can be separated.

  As an example of the fourth fixing bracket of the present invention, in the first fixing bracket, the second fixing bracket, and the third fixing bracket as described above, the adjusting bolt 6 and the adjusting nut 4b are used as connecting pins. The bolt hole 7 for the adjusting bolt 6 is replaced with a pin hole for the connecting pin. As described above, the two steel plates 5 (the angle member 8 and the channel member 9) do not need to be firmly fastened. When the two steel plates 5 are connected and fixed with the V bolt 3 and the fastening nut 4a. As long as the angle between the two steel plates 5 can be adjusted, a connecting pin and a pin hole can also be used as the fixture of the present invention. However, it is better to use a connecting pin and a pin hole so that the two steel plates 5 can be separated when assembling and mounting a fixing metal fitting in accordance with the same request as described above.

  As described above, the fixing bracket of the present invention can be firmly mounted at a predetermined position of a columnar body having a circular cross-sectional outer shape such as a steel pipe. Therefore, it is possible to secure a strong fixing point at a predetermined position of the columnar body. For example, a part of this fixing bracket, a V-bolt is attached with a pulley and an unloading operation is performed, or a wire rope with a carabiner is attached and the wire The rope can be used to hold other pole equipment. In such a case, when the opening of the V bolt is 75 degrees rather than 90 degrees, the gap between the cylinder or the like and the V bolt becomes larger, so attachment to the V bolt becomes easier.

  Moreover, the fixing metal fitting of this invention can be attached without the process to columnar bodies, such as a steel pipe. Therefore, it is also possible to attach the mounting bracket for the column-mounted equipment without affecting the columnar body side by performing welding or the like on the fixing bracket of the present invention. Further, the angle member of the fixing bracket of the present invention or the tip of the channel member can be extended and used, for example, as a part of a brace.
