Description

[Technical Field]

[0001] The present invention relates to a connector for a high-place installation member used to connect a high-place installation member, such as a lightning-strike-suppressing lightning rod, a prong-type lightning rod, or an antenna, to a support pole. [Background technology]

[0002] BACKGROUND ART Connectors have been available for erecting metal steel pipe support columns in buildings and attaching elevated installation members to the support columns.

[0003] In particular, the work of attaching the elevated installation members to the support columns is carried out at the highest point of the building, making welding and other operations difficult. Also, there are problems such as the elevated installation members attached to the support columns becoming loose over time due to wind pressure, etc., and becoming detached easily or making noise.

[0004] In view of this situation, a connector for a member to be installed at a height has been proposed, which can simply and reliably connect the member to a support column mechanically and electrically.

[0005] For example, Patent Document 1 describes a connector for a high-altitude installation member that includes a pair of split fittings arranged at opposing positions on the outer periphery of the support column, bolts and nuts that secure each split fitting to the support column, and bolts and nuts that fasten the split fittings to a high-altitude installation member that has a plunger. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Registered Utility Model No. 3178836 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the connecting device described in Patent Document 1, the horizontal part that supports the high-altitude installation component is provided in the holding part where the split fittings are fastened together, so the vibrations that occur when the high-altitude installation component is attached to the connecting device can cause the fastening of the split fittings together to loosen. Therefore, after the elevated installation member was attached to the connector, it was necessary to fasten the split metal fittings together again.

[0008] The present invention has been made in consideration of the above-mentioned circumstances, and its objective is to provide a connector that can be easily and reliably connected mechanically and electrically at the construction site, improves construction convenience, and prevents the joints between split fittings from loosening due to vibrations that occur when attaching high-altitude installation components to the connector. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention is a connector for connecting a flange provided on a high-altitude installation member to a support column that supports the high-altitude installation member, and comprises a plurality of split metal fittings arranged at opposing positions on the outer periphery of the support column, each of the split metal fittings having a retaining portion with a contact surface that contacts the outer periphery of the support column, a joint portion that joins the split metal fittings together, and a connection portion to which the flange is attached, and the connection portion is provided on the retaining portion.

[0010] According to the present invention, since the connection portion is provided in the holding portion, the elevated installation member and the support column can be easily connected mechanically and electrically at the construction site, and loosening of the fastening between the split fittings due to vibrations generated when attaching the elevated installation member to the connecting fixture can be prevented.

[0011] In a preferred embodiment of the present invention, each of the split fittings is provided with a plurality of the connecting portions.

[0012] With this configuration, the center of gravity of the connection part that supports the flange of the elevated installation member is closer to the center of gravity of the support column in a plan view, making it possible to attach the elevated installation member to the support column more stably.

[0013] In a preferred embodiment of the present invention, one of the connection portions is provided along a direction different from that of the other connection portions in a plan view.

[0014] This configuration makes it possible to prevent the connection portion from bending or the connection portion or connector from being damaged when the elevated installation member is struck by lightning or other impact.

[0015] In a preferred embodiment of the present invention, the holding portion is provided with a protruding portion that abuts against the flange.

[0016] With this configuration, the area of ​​the surface of the connector that comes into contact with the flange of the elevated installation member is increased, making it possible to more stably support the elevated installation member.

[0017] In a preferred embodiment of the present invention, the joints are provided on both sides of the holding portion in the width direction and extend in the height direction of the support column.

[0018] By adopting such a configuration, it is possible to improve the joining state between the split metal fittings.

[0019] In a preferred embodiment of the present invention, when the split fittings are joined together, the holding portion has a polygonal cross section.

[0020] This configuration allows the split fitting to be pressed against the outer surface of the support pole at multiple points, thereby improving the fixation between the split fitting and the support pole. [Effects of the Invention]

[0021] According to the present invention, it is possible to provide a connector that can be easily and reliably connected mechanically and electrically at the construction site, improving the convenience of construction and preventing the joints between split metal fittings from loosening due to vibrations that occur when attaching elevated installation components to the connector.

[0023] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. The embodiment shown below is an example of the present invention, and the present invention is not limited to the embodiment shown below. In these drawings, the symbol X indicates a connector according to this embodiment.

[0024] <Configuration> As shown in FIG. 1, the connector X comprises two split metal fittings 1, 1 arranged at opposing positions on the outer periphery of the support pole P, and a fixing means 2. In this embodiment, there are two split fittings, but there may be three or more.

[0025] Each split metal fitting 1, 1 has the same shape. This allows for one type of split metal fitting to be used, reducing the number of parts.

[0026] Each of the split metal fittings 1, 1 is formed by cutting, drilling and bending a single metal plate such as stainless steel or galvanized steel plate having a thickness of, for example, about 3 to 8 mm. By manufacturing each split metal fitting 1,1 using this type of processing, the time-consuming and costly welding process is no longer necessary, making it possible to reduce the manufacturing costs of the split metal fittings 1,1.

[0027] As shown in Figures 2 to 4, each split fitting 1, 1 has a retaining portion 11, 11 with a contact surface that contacts the outer peripheral surface of the support column P, a joining portion 12, 12 that joins the split fittings 1, 1 together, and a connecting portion 13, 13 to which the flange B3 of the high-altitude installation member B is attached.

[0028] The holding portions 11, 11 are provided with protruding portions 111, 111 that come into contact with the flange B3.

[0029] As shown particularly in FIG. 4, the protruding portions 111, 111 are provided at the center of the upper edge of the split fittings 1, 1 when viewed from the front. This brings the center of gravity of the surface that abuts against the flange B3 closer to the center of gravity of the support column in a plan view, making it possible to more stably attach the high-place installation member to the support column.

[0030] Furthermore, the holding portions 11, 11 are bent into the shape of a hexagonal tube split vertically in half, and are therefore formed so that when the split fittings 1, 1 are joined together, they have a hexagonal cross section. The cross section of the split fittings 1, 1 does not have to be hexagonal when joined, and there are no restrictions on the shape as long as the retaining portions 11, 11 can be pressed against the outer surface of the support post. For example, the cross section may be octagonal.

[0031] The joints 12, 12 are provided on both sides of the width direction of each holding portion 11, 11 and extend in the height direction of the support column P.

[0032] Furthermore, first bolt holes 121 are provided in the joints 12.

[0033] A plurality of first bolt holes 121, 121 are provided along the height direction of the support pillar P. This makes it possible to press each split metal fitting 1, 1 firmly against the support column P by tightening the split metal fittings in a direction that brings them closer together using bolts and nuts, which will be described later.

[0034] Two connection portions 13, 13 are provided along the edge of each of the holding portions 11, 11. In particular, the connection portions 13, 13 are arranged in a V-shape in plan view, as shown in Fig. 4, so that one connection portion 13, 13 is provided in a different direction from the other connection portions 13, 13 in plan view.

[0035] The connecting portions 13, 13 are formed in a tongue shape and are bent so as to be perpendicular to the height direction of the holding portions 11, 11.

[0036] Furthermore, the connecting portions 13, 13 are provided with second bolt holes 131, 131 that correspond to the flange B3 (see FIG. 6).

[0037] The fixing means 2 has first fixing means 21 for fixing the split fittings 1, 1 together, and second fixing means 22 for fixing the high-place installation member B (see FIG. 6) to the connecting portions 13, 13.

[0038] The first fixing means 21 includes a bolt 21a to be inserted into the first bolt holes 121, 121, and a plurality of nuts 21b into which the bolt 21a is inserted. This makes it possible to fasten the split fittings 1 together. Furthermore, because multiple nuts 21b are fastened to one bolt 21a, the fastened state of the first fixing means 21 is prevented from loosening.

[0039] Similarly, the second fixing means 22 includes a bolt 22a to be inserted into the second bolt holes 131, 131, and a plurality of nuts 22b into which the bolt 22a is inserted. This makes it possible to attach the high-place installation member B to the connection portions 13, 13. Furthermore, since multiple nuts 22b are fastened to one bolt 22a, loosening of the fastened state of the second fixing means 22 is prevented.

[0040] Furthermore, the bolt 21a and the nut 21b may be the same as the bolt 22a and the nut 22b, respectively. This allows for one type of fixing means to be used, thereby reducing the number of parts.

[0041] In this embodiment, the high-place installation member B is a lightning strike suppression type lightning rod. The elevated installation member B may be a needle-shaped lightning rod or an antenna.

[0042] The lightning-suppression type lightning rod B includes a lightning pole member B1, a support rod B2 that holds the lightning pole member B1 in the height direction of the support pole P, and a flange B3 that is screwed to the lower part of the support rod B2. The flange B3 is provided with a plurality of bolt holes B31. In this embodiment, the flange B3 has a circular shape in a plan view.

[0043] <How to use> Hereinafter, a method of using the connector X will be described with reference to FIGS.

[0044] When connecting the lightning-suppressing lightning rod B to the support pole P, the user first places the split metal fittings 1, 1 at opposing positions on the outer periphery near the tip of the support pole P, as shown in FIG.

[0045] Next, the user inserts bolt 21a into first bolt holes 121, 121, and then inserts bolt 21a into nut 21b, thereby fastening the split fittings together. In this way, the connector X can be fixed to the support pole P as shown in FIG.

[0046] Next, the user places the flange B3 of the lightning-strike-suppressing lightning rod B on the connecting portions 13, 13 and the protruding portions 111, 111, as shown in FIG. At this time, the bolt holes B31 of the flange B3 and the second bolt holes 131, 131 are arranged to align with each other.

[0047] Next, the user inserts the bolt 22a into the bolt hole B31 and the second bolt holes 131, 131, and then inserts the bolt 22a into the nut 22b to fasten them together.

[0048] In this way, it becomes possible to connect the high-place installation member B to the support column P using the connector X, as shown in FIG.

[0049] <Effects> According to this embodiment, by providing connection portions 13, 13 on each holding portion 11, 11, it is possible to easily connect the high-altitude installation member B and the support column P mechanically and electrically at the construction site, and to prevent the joint between the split fittings 1, 1 from loosening due to vibrations that occur when attaching the high-altitude installation member B to the connector X.

[0050] In addition, since each split fitting 1, 1 has multiple connection portions 13, 13, the center of gravity of the connection portions 13, 13 that support the flange B3 in a planar view is closer to the center of gravity of the support column P, making it possible to attach the high-altitude installation member B to the support column P more stably.

[0051] Furthermore, since one of the connection parts 13, 13 is arranged in a different direction from the other connection parts 13, 13 when viewed in a plane, it is possible to prevent the connection parts 13, 13 from bending or the connection parts 13, 13 or the connector X from being damaged when the high-altitude installation member B is subjected to an impact such as lightning strike.

[0052] In addition, the holding portions 11, 11 are each provided with protrusions 111, 111 that abut against the flange B3, thereby increasing the surface area of ​​the connector X that abuts against the flange B3, making it possible to support the elevated installation member B more stably.

[0053] Furthermore, by providing the joints 12, 12 on both sides of the holding portions 11, 11 in the width direction and extending in the height direction of the support pillar P, it is possible to improve the joint state between the split fittings 1, 1.

[0054] Furthermore, when the split fittings 1, 1 are joined together, the holding portions 11, 11 are formed with a polygonal cross section, which allows multiple locations of the split fittings 1, 1 to be pressed against the outer surface of the support column P. This makes it possible to improve the fixed state between the split fittings 1, 1 and the support column P.

[0055] <Example of change> The shapes and dimensions of the components shown in the above-described embodiment are merely examples and can be modified in various ways based on design requirements, etc.

[0056] For example, instead of providing the protruding portions 111, 111, auxiliary connection portions (not shown) extending outward from the holding portions 11, 11 in a plan view may be provided. By doing so, the area of ​​the surface where the connector X abuts against the flange B3 increases, making it possible to support the high-place installation member B even more stably.

[0057] For example, the first fastening means 21 and the second fastening means 22 may include washers (not shown). This prevents the fastening between the bolts 21a, 22a and the nuts 21b, 22b from loosening, and also prevents the connecting portions 13, 13 and the flange B3 from being damaged by rotation of the bolts 21a, 22a.
