Temporary connector for split beam flange

Abstract

This invention provides a temporary connector for split beam flanges that reduces the burden of installation work at high altitudes and can be used with beam flanges of different sizes or with different spacing (pitch) between bolt holes in the flange. [Solution] The beam 1 is fixed to the support column by sandwiching the support column 4 between one arc-shaped band portion 5 and the other arc-shaped band portion 6, which have beam fixing portions. One or more one-side fixing plates 12 are connected to one end of one arc-shaped band portion of the split beam flange, one or more other-side fixing plates 13 are connected to one end of the other arc-shaped band of the beam flange that is opposite to one end of the one arc-shaped band portion, and a rod body 11 is formed by connecting the base of the one-side fixing plate and the base of the other-side fixing plate so as to be tiltable around an axis. Thus, one arc-shaped band portion and the other arc-shaped band portion are connected to the rod body so as to be tiltable around an axis. Conventionally, it was not easy to attach a split beam flange to a support column.

Description

Technical Field

[0001] The present invention relates to a temporary connector for temporarily connecting a beam flange divided into two parts, such as when attaching it to a support column.

Background Art

[0002] For example, as shown in FIG. 9, a beam 1 horizontally installed to support overhead lines or the like is fixed between support columns 4, 4 such as left and right utility poles vertically installed with a line 3 or the like sandwiched therebetween through beam flanges 2, 2 at both ends of the beam 1.

[0003] As shown in FIGS. 10 and 11, the beam flange 2 is composed of one arc-shaped band portion 5 and the other arc-shaped band portion 6 separated into two parts. A beam fixing portion 7 for fixing the end portion 1a of the beam 1 is formed on the one arc-shaped band portion 5.

[0004] Then, the support column 4 is sandwiched between the one arc-shaped band portion 5 and the other arc-shaped band portion 6 separated into two parts. One and the other one-side flange portions 5a, 5b formed at both ends of the one arc-shaped band portion 5 and one and the other other-side flange portions 6a, 6b formed at both ends of the other arc-shaped band portion 6 are opposed to each other. A plurality of bolt through holes 5c formed in the one and the other one-side flange portions 5a, 5b and bolt through holes 6c formed in the one and the other other-side flange portions 6a, 6b formed at positions corresponding to the respective through holes 5c are respectively inserted with bolts 8, and nuts 9 are screwed onto the bolts 8 and tightened, thereby connecting the one arc-shaped band 5 and the other arc-shaped band 6 and tightening the support column 4 so that the beam flange 2 can be fixed to the support column 4.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the beam flange 4 mentioned above weighed about 100 kg, making the task of connecting the two separated beam flanges at a high altitude a significant burden for the workers.

[0006] This invention aims to eliminate the above-mentioned drawbacks. [Means for solving the problem]

[0007] The temporary connector for a utility pole band of the present invention is characterized in that the one arc-shaped band portion and the other arc-shaped band portion sandwich the support column and fix the beam to the support column by the two-part beam flange, one or more one-side fixing plates connected to one end of the one arc-shaped band portion of the two-part beam flange, one or more other-side fixing plates connected to the end of the other arc-shaped band of the beam flange that is opposite to the one end of the one arc-shaped band portion, and a rod body that connects the base of the one-side fixing plate and the base of the other-side fixing plate so as to be tiltable around an axis, wherein the one arc-shaped band portion and the other arc-shaped band portion are each connected to the rod body so as to be tiltable around an axis.

[0008] Furthermore, the one-side fixing plate is characterized in that it comprises a base made of a cylindrical portion into which the rod is inserted, and a one-side plate body fixed to the base, having a surface parallel to the axis of the cylindrical portion and having a bolt through hole; the other-side fixing plate is characterized in that it comprises a base made of a cylindrical portion into which the rod is inserted, and a other-side plate body having a surface parallel to the axis of the cylindrical portion and having a bolt through hole; the one-side fixing plate is configured to be connected to the one arc-shaped band portion by inserting a bolt into the bolt through hole of the one-side plate body and a bolt through hole formed at one end of the one arc-shaped band portion and tightening it with a nut; and the other-side fixing plate is configured to be connected to the other arc-shaped band portion by inserting a bolt into the bolt through hole of the other-side fixing plate and a bolt through hole formed at one end of the other arc-shaped band portion and tightening it with a nut.

[0009] Furthermore, the one-sided plate is fixed to the cylindrical base of the one-sided fixing plate at a position eccentric with respect to the axial center of the cylindrical portion, and the other-sided plate is fixed to the cylindrical base of the other fixing plate at a position eccentric with respect to the axial center of the cylindrical portion. [Effects of the Invention]

[0010] According to this invention, by using a temporary connector, one separated arc-shaped band portion 5 and the other arc-shaped band portion 6 can be connected in an expandable manner, thereby reducing the burden of installation work at high places on the beam flange.

[0011] Furthermore, even with beam flanges of different sizes or beam flanges with different spacing (pitch) between bolt holes in the flange portion, the temporary connector for beam flanges of this invention can be used by making the fixing plate axially movable relative to the rod body.

[Modes for carrying out the invention]

[0013] Embodiments of the present invention will be explained below with reference to the drawings.

[0014] Note that parts that are the same as in previous explanations will be marked with the same symbols, and the explanations will be omitted. [Examples]

[0015] In this invention, as shown in Figures 1 to 8, a temporary connector 10 for the beam flange is used to connect one side flange portion 5a of one of the arc-shaped band portions 5 to the other side flange portion 6a of the other arc-shaped band portion 6, which is opposite to the one side flange portion 5a, so that they can tilt freely.

[0016] Then, as shown in FIG. 7, the one arcuate band portion 5 and the other arcuate band portion 6 are opened, the column 4 is inserted, and then, as shown in FIG. 8, the one arcuate band portion 5 and the other arcuate band portion 6 are closed to sandwich the column 4. After connecting the other one-side flange portion 5b of the one arcuate band portion 5 and the other other-side flange portion 6b of the other arcuate band portion 6 with bolts 8 and nuts 9, the temporary connector 10 is removed, and the one one-side flange portion 5a of the one arcuate band portion 5 and the one other-side flange portion 6a of the other arcuate band portion 6 are connected and tightened with bolts 8 and nuts 9, so that the beam flange 2 can be attached to the column 4.

[0017] Specifically described below.

[0018] As shown in FIGS. 1 to 4, the temporary connector 10 of the beam flange of the present invention includes a rod body 11 having a circular cross-section, and one or a plurality of one-side flange fixing plates 12 provided rotatably in the axial direction on the rod body 11 and fixed to the one one-side flange portion 5a of the one arcuate band portion 5, and one or a plurality of the other-side flange fixing plates 13 fixed to the one other-side flange portion 6a of the other arcuate band portion 6, bolts 14 inserted into the through hole 5c of the one one-side flange portion 5a and the through hole 12a formed in the one-side flange fixing plate 12, nuts 15 screwed and tightened to the bolts 14, bolts 14 inserted into the through hole 6c of the one other-side flange portion 6a and the through hole 13a formed in the other-side flange fixing plate 13, and nuts 15 screwed and tightened to the bolts.

[0019] Further, the one and the other flange fixing portions 12, 13 are each composed of a base portion 16 having a cylindrical portion having a through hole 16a into which the rod body 11 is inserted, and a plate body 17 fixed to the base portion 16 and having a surface parallel to the axis of the through hole 16a of the cylindrical portion 16 and in which the bolt through holes 12a, 13a are formed, as shown in FIGS. 3 and 4.

[0020] Furthermore, as shown in Figure 4, the plate body 17 is provided at an eccentric position relative to the base 16 with respect to the axis center of the through hole 16a of the cylindrical body (i.e., it is provided at a position such that the extension of the surface of the plate body 17 does not coincide with the axis), and as shown in Figures 7 and 8, it is formed to facilitate connection of the plate body 17 between the one side flange portion 5a and the other side flange portion 6a of the one side, which are spaced apart from each other.

[0021] In addition to being provided separately from the plate body 17, the nut 15 may also be fixed to the plate body 17, as shown in Figure 4.

[0022] Furthermore, as shown in Figure 14, the bolt through holes 12a and 13a themselves may be formed as nuts 15.

[0023] Next, we will explain how to install the temporary connectors for the beam flanges.

[0024] First, one or more through-holes in the one-side flange fixing plate 12 and one or more through-holes in the other-side flange fixing plate 13 are inserted from one end of the rod 11. Then, nuts 18 are screwed onto both ends of the rod 11 to prevent the flange fixing plates 12 and 13 from coming out of both ends of the rod.

[0025] This forms the temporary connector 10.

[0026] In addition, the one-sided flange fixing plate 12 and the other-sided flange fixing plate 13 may be inserted into the rod body 11 either alternately from the upper end or randomly.

[0027] In this embodiment, an example is shown in which four flange fixing plates 12, 13 are rotatably inserted into the rod 11, and each flange fixing plate 12, 13 is formed so that it cannot move in the axial direction of the rod 11. However, for example, two flange fixing plates 12, 13 may be provided on the rod 11 and configured to be movable in the axial direction relative to the rod 11.

[0028] With this configuration, the temporary connector can be used even if the beam flanges are of different sizes or if the bolt hole pitches on the flange portion of the beam flanges are different.

[0029] Then, by placing the one-side flange fixing plate 12 of the temporary connector 10 of the present invention opposite the one-side flange portion 5a of the one-side arc-shaped band portion 5, inserting the bolt 14 into the through hole 12a of the one-side flange fixing plate 12 and the through hole 5c of the one-side flange portion 5, screwing it onto the nut 15, and tightening it, the one-side flange fixing plate 12 is fixed to the one-side arc-shaped band portion 5, and the one-side arc-shaped band portion 5 is connected to the rod body 11 so as to be able to tilt around its axis.

[0030] Similarly, by placing the other flange fixing plate 13 of the present invention opposite the other flange portion 6a of the other arc-shaped band portion 6, inserting a bolt 14 into the through hole 13a of the other flange fixing plate 13 and the through hole 6c of the other flange portion 6a, screwing it onto a nut 15, and tightening it, the other flange fixing plate 13 is fixed to the other arc-shaped band portion 6, and the other arc-shaped band portion 6 is connected to the rod 11 so as to be able to tilt around its axis.

[0031] As a result, one of the arc-shaped band portions 5 and the other arc-shaped band portion 6 are connected to the rod 11 via the temporary connector 10 so as to be tiltable.

[0032] Then, the connected beam flange 2 is raised to the desired position on the support column 4, and the one arc-shaped band portion 5 and the other arc-shaped band portion 6 are tilted open using the rod 11 as an axis, the support column 4 is inserted between them, and then the one arc-shaped band portion 5 and the other arc-shaped band portion 6 are closed to sandwich the support column 4.

[0033] Next, the flange portion 5b on one side of the other arc-shaped band portion 5 and the flange portion 6b on the other side of the other arc-shaped band portion 6 are connected by a bolt 8 and a nut 9.

[0034] As a result, the beam flange on the other end is connected, so the bolt 14 is removed from one arc-shaped band portion 5 and the other arc-shaped band portion 6, and the temporary connector 10 is removed.

[0035] Then, one flange portion 5a of one of the arc-shaped band portions 5 and the other flange portion 6a of the other arc-shaped band portion 6 are connected and tightened using a bolt 8 and a nut 9.

[0036] This allows the beam flange 2 to be fixed to the support column 4.

[0037] The connector 10 described above will then be used to attach other beams.

[0038] According to this invention, by using a temporary connector, one separated arc-shaped band portion 5 and the other arc-shaped band portion 6 can be connected in an expandable manner, thereby reducing the burden of installation work at high places on the beam flange.

[0039] Furthermore, even with beam flanges of different sizes or beam flanges with different spacing (pitch) between bolt holes in the flange portion, the temporary connector for beam flanges of this invention can be used by making the flange fixing plate axially movable relative to the rod body.
