Description

[Detailed explanation of the invention] This invention is the first utility model registered by the applicant.
This is related to the improvement of the "07425" iron pole branch line mounting bracket.To be more specific, it can be attached to angle members used for the vertical and horizontal members of steel towers, etc., and can be used not only to support branch lines of steel towers, but also for safes, pulleys, etc. This relates to a fitting for attaching to an angle material that can be used to suspend or support various other items.

Figures 1 and 2 show the "steel pole branch line mounting bracket" of the above-mentioned Utility Model Registration No. 1074259. Attach bolts and nuts 2 to each of these opposing ends to clamp the angle material 2, and attach two or more branch wire attachment plates to the projecting wood protruding from the outside to the above-mentioned outer square plate so that it can be freely rotated. However, since the branch wire mounting plate is provided only at the outer corner of the outer square plate, which is the outer corner of the angle material A, the direction of the branch wire is limited, and this mounting bracket is It was not possible to take branch lines from all directions or suspend gold wheels.

This idea was devised in consideration of these points, and can be attached to steel towers etc. regardless of whether the angle members are horizontal members, vertical members, or in any other direction.
The object of the present invention is to provide a fitting for attaching to an angle member that can support various objects such as pulleys and can apply loads from all directions and angles.

An embodiment of this invention will be explained below with reference to the drawings. 1 is an outer clamping piece in which two key-shaped plates are stacked in parallel at a constant interval, and 2 is the distance between the two plates of this outer clamping piece 1. This separating plate 2 is provided between each side of the key-shaped outer clamping piece 1.

Reference numeral 3 denotes an inner clamping piece in which two key-shaped plate bodies are stacked in parallel at a constant interval, and this inner clamping piece 3 has a protruding end 3a formed by bending both ends of each key-shaped plate body outward. These projecting ends 3a can be freely overlapped with the outer surfaces of both ends of the outer clamping piece 1.

Reference numeral 4 denotes a bolt passing through holes drilled in both ends of the outer clamping piece 1 and the protruding ends 3a at both ends of the inner clamping piece 3, 5 a nut screwed onto the tip of the bolt 4, and 6 the inner clamping piece 1.
A separating plate that maintains the distance between the two key-shaped plates that make up the
This separating plate 6 is provided between each side of the key-shaped inner clamping piece 3.

Reference numeral 7 denotes a bolt that holds the separating plate 2 of the outer clamping piece 1 made of wax, and 8 refers to a substantially bowl-shaped holding metal fitting in which the small diameter portion 7a at the tip of the bolt 7 is inserted loosely into its center hole 8a. The inward pressing of this presser fitting 8 is done by a hinge that passes through the tip of the bolt 7,
10 is a spring washer crowned on the outer periphery of the small diameter portion 7a between the presser metal fitting 8 and the stepped portion 7b of the pressing bolt 7;
Reference numeral 11 denotes a washer which presses between the spring washer 10 and the separation plate 2, and is fitted around the outer periphery of the bolt 7. Reference numeral 12 denotes a bolt passed between each key-shaped plate body at the corner of the outer clamping piece 1.
13 is a nut screwed onto the tip of this bolt 12; 14 is a link having an annular portion at one end capped on either the bolt 4 or 12; 15 is a nut 16 attached to the other end of this link 14; This is a hanging fitting that can be rotated freely.

This invention has the above structure, and in order to attach it to the angle material 17 used for the cross member of the arm of a steel tower etc., one bolt 4 and nut 5 are connected to the outer clamping piece 1 and the inner clamping piece 3.
The outer clamping piece 1 and the inner clamping piece 3 lock the angle member 17 so as to surround it, and the protruding end 3 of the inner clamping piece 3
Insert the bolt 4 again into the hole a and the hole at the end of the outer clamping piece 1, and tighten it with the nut 5.

In pressing, the bolt 7 is rotated to clamp the angle member 17 between the presser fitting 8 and the inner edge of the inner clamping piece 3, and this device is fixed to the angle member 17.

When fixing to the angle member 17, the link 14 with the hanging metal fitting 15 is placed on any bolt 4 or 12, and the metal wheel is suspended using the hanging metal fitting 15, and the branch line ends are connected to support the branch line. can do.

In this way, in this invention, bolts 4 or 12 are provided at three locations at the corners and both ends of the outer clamping piece 1 on the outside of the angle member 17, and the link 14 is rotatably attached to one of these. Moreover, since the hanging fitting 15 is rotatably provided on the link 14, the hanging fitting 1
5 can be provided at any angle.

Therefore, regardless of whether the angle member 17 is used to protect from rain or to catch rain, by attaching this device, the hanging fitting 15 can be directed in the same direction for loads in any direction as shown in FIGS. 7 and 8. The angle material 17 is not strained.

Therefore, by attaching this invention to the horizontal member of the tower arm and suspending the metal wheel using the hanging metal fitting 15, or by attaching a come-along to the electric wire or wire that is passed between the steel towers, the come-along and the hanging metal fitting 15 of this invention are connected. This invention can be attached to the vertical members of a steel tower and connected to the tower branch line to support the branch line as shown in FIG. 10.

In addition, this invention allows the link 14 to be detachably attached to the bolts 4 or 12 at three locations, as described above.
At the same time, links 14 are provided on three bolts 4 and 12,
It is also possible to simultaneously receive loads from three directions via the hanging fittings 15.

In addition, when the angle member 17 is a horizontal member, when attaching this invention to the angle member 17, as shown in FIG.
All you have to do is rotate the inner clamping piece 3 around one bolt 4 and lock it with the other bolt 4 and nut 5. Also, if the angle member 17 is a rain catcher as shown in FIG. 9B, the inner clamping piece 3 on the top surface of the angle member 17 and rotate the outer clamping piece 1 around one bolt 4 to lock the other bolt 4 and nut 5. In either case, the operator can use one hand to This device can be temporarily fixed to the angle member 17, and installation is extremely easy.

Furthermore, if this device is attached to the angle member 17 of the horizontal member of a steel tower arm and the metal wheel is suspended, this device will vibrate due to the extension of wires and electric wires, and there is a risk that the bolt 7 will loosen when pressed. In this case, pressing is performed using the small diameter portion 7a of the bolt 7.
Since a spring washer 10 is mounted on the outer periphery of the small diameter portion 7a between the stepped portion 7b and the presser metal fitting 8, this spring washer 10 is pressed against the presser metal fitting 8 by the bolt 7.
Since the stepped portion 7b is pressed down, the bolt 7 does not loosen even when the bolt 7 is pressed due to the above-mentioned vibration.

In addition, in this invention, the outer clamping piece 1 and the inner clamping piece 3 surround the angle member 17, and when pressing, the angle member 17 is clamped by the presser metal fitting 8 and the inner clamping member 3 by tightening the bolt 7. Even if the cross-sectional size of the material 17 is various, this invention can be used as long as it can be surrounded by the outer clamping piece 1 and the inner clamping piece 3 and can be abutted by the presser metal fitting 8.

As mentioned above, this device can be attached to the vertical members, horizontal members, and other angle members of steel towers, etc., and can apply loads from all directions. Therefore, it can be used for various purposes such as supporting metal wheels and pulleys, or supporting branch lines of steel towers, etc. It has the effect of supporting things.
