Description

Technical Field

[0001] The present invention relates to a connector for a high-place installation member used for connecting a high-place installation member such as a lightning strike suppression lightning rod, a protruding lightning rod, an antenna, etc. and a support column.

Background Art

[0002] Conventionally, there is a connector for erecting a support column of a metal steel pipe on a building and attaching a high-place installation member to the support column.

[0003] In particular, since the work of attaching a high-place installation member to a support column is performed at the top of a building, it has been difficult to perform operations such as welding. In addition, there have been problems such as the high-place installation member attached to the support column rattling due to wind pressure or the like over a long period of time and being easily detached or making noise.

[0004] Under such circumstances, a connector for a high-place installation member that mechanically and electrically connects a high-place installation member to a support column simply and reliably has been proposed.

[0005] For example, Patent Document 1 describes a connector for a high-place installation member including a pair of split fittings arranged at opposite positions on the outer periphery of a support column, bolts and nuts for fixing each split fitting to the support column, and bolts and nuts for fastening a high-place installation member including a split fitting and a branch.

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, in the connector described in Patent Document 1, the horizontal part that supports the member installed at a high altitude is provided in the holding part to which the divided fittings are fastened together. Therefore, vibrations that occur when attaching the member installed at a high altitude to the connector may cause the fastening between the divided fittings to loosen. Therefore, after attaching the components installed at high altitudes to the connectors, it was necessary to re-fasten the separate brackets together.

[0008] This invention has been made in view of the above-mentioned circumstances, and aims to provide a connector that can be easily and reliably connected mechanically and electrically at the construction site, improves the convenience of construction, and suppresses loosening of the joints between the divided fittings due to vibrations that occur when attaching high-altitude installation members to the connector. [Means for solving the problem]

[0009] The present invention, which solves the above problems, is a connector for a flange provided on a member installed at a high altitude and a support column that supports the member installed at a high altitude, comprising a plurality of dividing fittings arranged at opposing positions on the outer circumference of the support column, wherein each dividing fitting has a holding portion having a contact surface that contacts the outer surface of the support column, a joining portion that joins the dividing fittings together, and a connecting portion to which the flange is attached, and the connecting portion is provided on the holding portion.

[0010] According to the present invention, since the connecting portion is provided in the holding portion, it is possible to easily connect the high-altitude installation member and the support column mechanically and electrically at the construction site, and to suppress loosening of the fastening between the divided fittings due to vibrations that occur when attaching the high-altitude installation member to the connector.

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

[0012] This configuration brings the center of gravity of the connection point supporting the flange of the high-altitude installation component closer to the center of gravity of the support column in a plan view, thus enabling more stable attachment of the high-altitude installation component to the support column.

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

[0014] This configuration makes it possible to prevent the connection points from bending or the connection points and connectors from being damaged when the components installed at high altitudes are subjected to impacts such as lightning strikes.

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

[0016] This configuration increases the surface area of ​​the connector that contacts the flange of the elevated mounting member, thereby enabling more stable support of the elevated mounting member.

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

[0018] This configuration makes it possible to improve the connection between the separate metal fittings.

[0019] In a preferred embodiment of the present invention, the holding portion is formed in a polygonal cross-section when the divided fittings are joined together.

[0020] This configuration allows multiple points on the dividing bracket to be pressed against the outer surface of the support column. This makes it possible to improve the fixation between the dividing bracket and the support column. [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 suppressing loosening of the joints between the divided fittings due to vibrations that occur when attaching high-altitude installation members to the connector.

Mode for Carrying Out the Invention

[0023] Hereinafter, with reference to FIGS. 1 to 6, an embodiment of the present invention will be described. Note that the following embodiments are examples of the present invention, and the present invention is not limited to the following embodiments. In these drawings, reference numeral X indicates the connecting fitting according to the present embodiment.

[0024] <Configuration> As shown in FIG. 1, the connecting fitting X includes two split fittings 1, 1 arranged at opposite positions on the outer periphery of the support column P, and fixing means 2. In this embodiment, there are two split fittings, but three or more may be used.

[0025] Each of the split fittings 1, 1 has the same shape. As a result, it is possible to handle with one type of split fitting, and the number of parts can be reduced.

[0026] Each of the split fittings 1, 1 is formed by cutting, punching, and bending a single metal plate such as stainless steel or galvanized steel plate having a thickness of about 3 to 8 mm, for example. By manufacturing each of the segmented fittings 1, 1 using this method, time-consuming and costly welding is eliminated, making it possible to reduce the production cost of segmented fittings 1, 1.

[0027] As shown in Figures 2 to 4, each split fitting 1, 1 has a holding portion 11, 11 having a contact surface that contacts the outer surface of the support column P, a joining portion 12, 12 that connects 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 retaining parts 11, 11 are provided with protruding parts 111, 111 that abut against the flange B3.

[0029] The protruding parts 111, 111 are located in the center of the upper edges of the dividing fittings 1, 1 in a front view, as shown in Figure 4 in particular. As a result, the center of gravity of the surface that contacts flange B3 becomes closer to the center of gravity of the support column in a plan view, making it possible to attach the high-altitude installation member to the support column more stably.

[0030] Furthermore, the holding parts 11, 11 are bent to form a shape that is half the length of a hexagonal tube, so that when each of the divided fittings 1, 1 is joined together, the cross-section is hexagonal. Furthermore, the cross-section of each dividing fitting 1, 1 does not necessarily have to be hexagonal when joined together. The shape is not limited as long as the holding parts 11, 11 can be pressed against the outer surface of the support column. For example, they may be formed with an octagonal cross-section.

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

[0032] Furthermore, the joint portions 12, 12 are provided with first bolt holes 121, 121.

[0033] Multiple first bolt holes 121, 121 are provided along the height direction of the support column P. This allows the division fittings 1, 1 to be strongly pressed against the support column P by tightening them together in a direction that brings them closer together using bolts and nuts, as described later.

[0034] Two connecting parts 13, 13 are provided along the edges of each holding part 11, 11. In particular, as shown especially in Figure 4, the connecting parts 13, 13 are arranged in a V-shape in plan view, so that one connecting part 13, 13 is provided in a different direction from the other connecting parts 13, 13 in plan view.

[0035] Furthermore, the connecting parts 13, 13 are formed in a tongue shape and are bent perpendicular to the height direction of the holding parts 11, 11.

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

[0037] The fixing means 2 includes a first fixing means 21 for fixing the dividing fittings 1, 1 together, and a second fixing means 22 for fixing the high-altitude installation member B (see Figure 6) to the connecting parts 13, 13.

[0038] The first fixing means 21 includes a bolt 21a 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, 1 together. In addition, since multiple nuts 21b are fastened to a single bolt 21a, loosening of the fastened state of the first fixing means 21 is suppressed.

[0039] Similarly, the second fixing means 22 includes a bolt 22a 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-altitude installation member B to the connection parts 13, 13. In addition, since multiple nuts 22b are fastened to a single bolt 22a, loosening of the fastened state of the second fixing means 22 is suppressed.

[0040] Furthermore, bolt 21a and nut 21b may be identical to bolt 22a and nut 22b, respectively. This allows for the use of only one type of fastening method, thus reducing the number of parts.

[0041] In this embodiment, the high-altitude installation member B is a lightning rod designed to suppress lightning strikes. The high-altitude installation component B may also be a pointed lightning rod or an antenna.

[0042] The lightning suppression type lightning rod B comprises a lightning electrode member B1, a support rod B2 that holds the lightning electrode member B1 in the height direction of the support column P, and a flange B3 screw-connected to the lower part of the support rod B2. The flange B3 is provided with a plurality of bolt holes B31. In this embodiment, flange B3 is circular in shape when viewed from above.

[0043] <How to use> The method of using connector X will be explained below with reference to Figures 1, 2, 5, and 6.

[0044] When connecting the lightning-suppressing lightning rod B to the support pole P, the user first positions the dividing fittings 1, 1 at opposing positions on the outer circumference near the tip of the support pole P, as shown in Figure 2.

[0045] Next, the user fastens the split fittings together by inserting the bolts 21a into the first bolt holes 121, 121 and then inserting the bolts 21a into the nuts 21b. By doing so, the connector X can be fixed to the support column P, as shown in Figure 1.

[0046] Next, the user places the flange B3 of the lightning suppression type lightning rod B on the connecting parts 13, 13 and the protruding parts 111, 111, as shown in Figure 5. At this time, the bolt holes B31 of flange B3 and the second bolt holes 131, 131 are positioned to align with each other.

[0047] Next, the user inserts bolts 22a into bolt hole B31 and second bolt holes 131, 131 respectively, and then fastens the bolts 22a into nuts 22b.

[0048] In this way, as shown in Figure 6, it becomes possible to connect the high-altitude installation member B to the support column P using the connector X.

[0049] <Effects> According to this embodiment, since the connecting parts 13, 13 are provided on each holding part 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 suppress loosening of the joint between the dividing fittings 1, 1 due to vibrations that occur when attaching the high-altitude installation member B to the connector X.

[0050] Furthermore, since each split fitting 1, 1 is provided with multiple connecting parts 13, 13, the center of gravity of the connecting parts 13, 13 that support the flange B3 in a plan 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 positioned in a different direction from the other connection parts 13, 13 in a plan view, it is possible to suppress the bending of the connection parts 13, 13 or damage to the connection parts 13, 13 or the connector X when the high-altitude installation member B is subjected to an impact such as lightning.

[0052] Furthermore, since the holding parts 11, 11 are each provided with protruding parts 111, 111 that abut against the flange B3, the surface area of ​​the connector X that abuts against the flange B3 is increased, making it possible to support the high-altitude installation member B more stably.

[0053] Furthermore, since the joint portions 12, 12 are provided on both sides in the width direction of the holding portions 11, 11 and extend in the height direction of the support column P, it is possible to improve the joining state between the dividing fittings 1, 1.

[0054] Furthermore, in the joined state of each dividing fitting 1, 1, the holding portion 11, 11 is formed with a polygonal cross-section, allowing multiple points of the dividing fitting 1, 1 to be pressed against the outer surface of the support column P. This makes it possible to improve the fixing state between the dividing fitting 1, 1 and the support column P.

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

[0056] For example, instead of having protruding parts 111, 111, auxiliary connecting parts (not shown) extending outward from the holding parts 11, 11 in a plan view may be provided. By doing so, the surface area of ​​the connector X that contacts the flange B3 increases, making it possible to support the elevated installation member B even more stably.

[0057] For example, the first fixing means 21 and the second fixing means 22 may include washers (not shown). This method prevents the bolts 21a and 22a from loosening and the nuts 21b and 22b from being damaged by the rotation of the bolts 21a and 22a. [Explanation of symbols]
