Description

TECHNICAL FIELD The present invention relates to a service wire mooring fitting for mooring a service wire drawn from a utility pole to a building such as a house.

Conventionally, when pulling a service wire into a building, the service wire can be pulled into the building by attaching a service arm to the eaves girder or wall surface under the eaves, and mooring the service wire to the tip of the service arm via an insulator and a mounting hook. It is done.

For example, the lead-in cross arm according to Patent Document 1 is made of L-shaped angle steel and attached to a wall as a fixed piece at half the length of one piece of the cross-arm. A holding hole is provided at the tip of the wire, and the lead-in wire is moored in this holding hole via a bidless insulator and a mounting hardware (mounting hook).

Such a lead-in arm is attached to the wall by passing three screws through holes provided in the fixing piece.

The wire anchoring fitting according to Patent Document 2 has two mounting plates attached to the bifurcated portion of a Y-shaped protruding plate via a hinge, and these two mounting plates are attached to a wall portion forming a right angle of the building. Hidden or gable board, etc.), and the service line is moored to the holding hole provided at the tip of the overhang board via a mounting hook and a stay insulator.

Such wire anchoring fittings are attached to the wall of a building by passing nails, wood screws, coach screws, etc. through through holes formed in the two mounting plates.

As described above, in conventional service wire cross arms and electric wire anchoring fittings, the point at which the service wire is anchored is the tip of the cross arm or overhang plate, and screws, nails, etc., are attached to the walls of the building. It was common to install with

JP 2013-143870 A JP-A-9-233660

However, in the lead-in wire arms and wire anchoring fittings according to Patent Documents 1 and 2, the point where the lead-in wire is anchored is the tip of the arm or overhang plate, so it is difficult to attach the lead-in wire to the outer wall from the mooring position of the lead-in wire. There is a problem that the distance to the part is long and a large load is applied to the mounting part of the outer wall.

In other words, a service line that is led from a utility pole to a building is subject to a load due to the weight of the wire or cable that is the service line, as well as a load due to wind and a load due to accumulated snow on the wire. A considerable load has been applied to the arm.

Also, in recent years, power equipment has become larger due to the spread of air conditioners, etc., and it is thought that one of the causes is that the lead-in wires have become thicker accordingly.

For this reason, especially in recent years, Western-style houses without ridge beams have become popular, and if the siding board where there are no pillars inside is fixed directly with a lead-in cross arm or wire anchoring metal fitting with screws, the siding board may be damaged or damaged. There have been many problems with mounting plate screws coming off.

Therefore, it may be possible to shorten the length of the lead-in cross arm and the wire anchoring fitting, but if the length is shortened, there is another problem that a short-circuit accident occurs due to contact with the outer wall of the lead-in wire.

Such problems are caused by various environments in which the service line is drawn into the building, such as the position of the utility pole, the position at which the service line is drawn into the building, and the angle of the service line with respect to the wall.

Therefore, according to the present invention, even if there are various environments for drawing the service line into the building, such as the position of the utility pole, the position where the service line is drawn into the building, the angle of the service line with respect to the wall part, etc., the installation state to the outer wall can be adjusted according to the environment. To provide a mooring fitting for service line which is good and does not cause a short-circuit accident.

In order to solve the above problems, the invention according to claim 1 is a service wire mooring fitting that is attached to the outer wall of a building or the corner of a building material and mooring the service wire via an insulator and a mounting hook, two mounting plates, a pull-in cross arm clamping portion for clamping an L-shaped pull-in cross arm between at least one of the mounting plates and the outer wall or building material; a holding hole for holding a mounting hook, and when there is no fear that the lead-in wire will come into contact with the outer wall or building material, the lead-in wire is moored in the holding hole via the mounting hook and the insulator, and the lead-in wire is When there is a risk of contact with the outer wall or the building material, the retraction arm clamping part clamps the retraction cross arm between the retraction arm clamping part and the outer wall or building material, The lead-in wire is moored to the holding hole of the lead-in arm via the mounting hook and the insulator.

The invention according to claim 2 is the service wire mooring fitting according to claim 1, characterized in that a single metal plate formed into a predetermined shape is formed by bending.

The invention according to claim 3 is the lead-in wire mooring fitting according to claim 1 or claim 2, wherein the two mounting plates are provided with the lead-in arm holding portions, respectively. do.

According to the first aspect of the invention, since it is attached to the outer wall of the building or the corner of the building material with two orthogonal mounting plates, it is resistant to forces from not only one direction but also from multiple directions, and the mooring for the lead-in wire The attachment of metal fittings can be strengthened.

This allows the distance from the attachment point to the outer wall to the mooring position of the service line to be long. Enables stable spur mooring regardless of the mooring position.

Therefore, according to the present invention, a mounting plate attached to an outer wall of a building or a corner of a building material is provided with an L-shaped lead-in cross arm clamping portion that clamps the L-shaped lead-in cross arm between the outer wall or the building material. If the lead-in wire is close to an outer wall or the like and there is a risk of contact, the lead-in arm can be used to separate the lead-in wire from the outer wall or the like as much as possible.

If there is no risk of contact with the outer wall of the service wire, the service wire can be directly moored via the insulator and the mounting hook by providing a holding hole for holding the mounting hook in the service arm holding portion. can be done. In this case, the mounting position of the mounting hook on the outer wall of the mounting plate and the mooring position of the lead-in wire are close to each other, so the load on the mounting plate is reduced. accidents can be reduced.

Although there are various environments for drawing the service line into the building, such as the position of the utility pole, the position at which the service line is drawn into the building, the angle of the service line with respect to the wall, etc., according to the present invention, the service line can be adapted to the building by adapting to each environment. It is possible to pull in.

According to the second aspect of the invention, the lead-in wire mooring fitting is formed by bending a single metal plate, so that it can be manufactured easily and inexpensively.

According to the third aspect of the invention, the two mounting plates attached to the corners of the outer wall or the like are provided with the lead-in cross arm clamping portions, respectively. , and the versatility can be further enhanced.

The spur wire mooring fitting 1 has a substantially L-shape as a whole, and is formed in a symmetrical shape with respect to the corner 1c. It is formed to contact two surfaces.

Further, a ridge 12a that protrudes greatly outward is provided between the corner 1c side of the mounting plate 11 and the edge 1e. A pressing plate 12b for pressing the pull-in arm 30 is formed in a flat space from the base edge to the edge 1e side.

A space having an L-shaped cross section is formed by the inside of the ridge 12a and the flat space, and the lead arm 30 is accommodated in this space.

The ridge 12a and the pressing plate 12b form the pull-in cross arm clamping portion 12 that clamps the pull-in cross arm 30 between the outer wall 20 or the building material 21. As shown in FIG. In this embodiment, a load provided with two pull-in cross arm holding portions 12 will be described.

A through hole 12c for passing a bolt 13 for bolting a pull-in arm 30 fitted therein is formed in the projecting strip 12a of the pull-in arm clamping portion 12, and a pull-in arm is formed in the retainer plate 12b. A screw insertion hole 12d for inserting a screw 14 for screwing the metal 30 to the outer wall 20 or the building material 21 is formed.

The lead-in arm 30 is made of L-shaped angle steel, and has a holding hole 31 formed at one end for mooring the lead-in wire 4 via the insulator 2 and the mounting hook 3 . A plurality of holding holes 31 are formed in the lead-in arm 30 so that the lead-in wire 4 can be moored at a position suitable for the environment.

A through hole (reference numeral is omitted) is formed at a position facing the through hole 12c of the protruding line 12 in one piece of the L-shaped lead-in arm clamping portion 12 that is fitted to the protruding line 12a. Further, the other piece is formed with a screw insertion hole (the reference numeral is omitted) at a position facing the screw insertion hole 12d of the pressing plate 12b.

A holding hole 15 is formed in the central portion sandwiched between the two through holes 12c of the ridge 12a. The service wire 4 can be directly moored to the service wire mooring fitting 1.

A plurality of screw insertion holes 11a are formed in the portion on the edge 1e side of the mounting plate 11, and screws 14 are inserted through these screw insertion holes 11a when the lead-in mooring fitting 1 is attached to the outer wall 20 or the building material 21. It is designed to be screwed down. The screw insertion holes 11a are formed in a plurality of rows in the width direction of the mounting plate 11, and two rows are shown in the drawing.

An example of using the mooring fitting 1 for the service wire formed in this way is attached to the eaves girder (building material 21) under the eaves of a Japanese house, and an example of using it attached to the corner of the outer wall of a Western-style house without eaves girder is given. explain.
(Usage example 1)
FIGS. 6 to 8 will explain a case in which the lead-in mooring fitting 1 is attached to the eaves girder (building material) of a Japanese house and the lead-in arm 30 is used.

In many Japanese houses, it is common to form a lead-in hole in a wall portion inside the eaves 40 which is not exposed to the weather, and lead the lead-in wire 4 into the house through this lead-in hole. In order to moor the service wire 4 under the eaves 40, when the service wire 4 is pulled into the space under the eaves 40, the distance from the wall to the mooring position should be as far as possible so that the service wire 4 does not come into contact with the roof, fascia, gable plate, etc. It is necessary to gain some distance, and a lead arm 30 is used.

To attach the lead-in arm 30 to the lead-in wire mooring fitting 1, one piece of the L-shaped lead-in arm 30 is fitted into the ridge 12a, and the through hole 12c of the ridge 12a and the lead-in arm are fitted. A bolt 13 is inserted through a through hole (reference numerals omitted) of the gold 30 and fixed with a nut 16 .

Next, the two mounting pieces 11 of the service wire mooring fitting 1 to which the lead-in arm 30 is mounted are pressed against both sides forming the corner 1c of the eaves girder 21, and the screws 14 are inserted into the screw insertion holes 11a and screwed. .

At this time, the other side of the lead-in arm 30 comes into contact with the eaves girder 21, and by inserting the screw 14 into the screw insertion hole 12d of the retainer plate 12b and screwing it, the other side of the lead-in arm 30 is is pressed against the eaves girder 21.

In this way, the lead-in arm 30 is attached to the ridge 12 of the mooring fitting 1 for the lead-in wire, and the mounting plate 11 and the holding plate 12 are screwed to the eaves girders 21. The mooring fitting 1 can be attached to the eaves girder 21. - 特許庁

Since the spur wire mooring fitting 1 is screwed to the eaves girder 21 made of wood, it can be firmly attached. , the attachment of the lead-in mooring fitting 1 can be strengthened because it has resistance to forces from multiple directions.

In particular, it can be used even when the lead-in arm 30 is used and the distance between the attachment portion to the eaves girder 21 and the mooring position of the lead-in wire 7 is increased.
(Usage example 2)
FIG. 9 illustrates a case where the lead-in mooring fitting 1 is attached to the outer wall 20 of a house without eaves girders.

A siding board is often used as the outer wall 20 in a Western-style house, and for construction of this siding board 20, for example, first, a heat insulating material 42 is arranged between the pillars 41 as structural materials, and the outer side is placed. A compound panel 43 as a base is pasted on. Next, the siding board 20 is installed on the outside of the control panel 43. In order to provide a gap (ventilation layer) 44 between the siding board 20 and the control panel 43, furring strips 45 are arranged at predetermined intervals, The siding board 20 is screwed to this furring strip 45 .

In order to attach the service wire mooring fitting 1 to the corner of the siding board 21 thus constructed, the two mounting plates 11 of the service wire mooring fitting 1 are attached to the two surfaces forming the corners of the siding board 20, respectively. Then, the screws 14 are inserted into the screw insertion holes 11a of the mounting plate 11 and screwed to the siding board 20. As shown in FIG.

At this time, it is difficult to know which part of the furring strip 45 or the space 44 the screw is attached to. Even if the screws 14 inserted through the screw insertion holes 11 a of the row 1 hit the gap 44 , the other screw insertion holes 11 a almost always hit the furring strip 45 .

This is because the corners are also provided with voids 44 as ventilation layers, but the furring strips 44 are arranged at positions that are not very far from the corners when the siding board 20 is constructed. is fixed to furring strip 44 by screw 14.

Further, even if the inserted screw 14 hits the gap 44 , if a relatively long screw 14 is used, the screw 14 reaches the control panel 43 and is screwed to the control panel 43 .

Since the siding wire mooring fitting 1 attached to the siding board 20 in this way is not provided inside the above-mentioned eaves 40, it is not obstructed by the roof, fascia, gable plate, etc., so that the siding wire 4 can be secured. It can be directly moored in the holding hole 15 of the mooring fitting 1 for service line via the insulator and the mounting hook.

Even if the mounting plate 11 of the lead-in mooring fitting 1 is screwed into the gap 44 (control panel 43), the attachment portion and the lead-in wire 4 can be moored like the lead-in arm 30 described above. Since the distance from the holding hole 15 is short, the load applied to the mounting plate 11 is small, so that damage to the sizing board 20 and loss of screwing of the mounting plate can be reduced.

Of course, when the service wire mooring fitting 1 is attached to the siding board 20, the service arm 30 can also be attached as described above.

As described above, according to this lead-in mooring fitting 1, since it is attached to the outer wall 20 of the building or the corner of the building material 21 with two orthogonal mounting plates 11, it can withstand forces from not only one direction but also multiple directions. It has resistance and can strengthen the attachment of the mooring fitting 1 for the service wire.

In addition, even when the service wire mooring fitting 1 is used alone, or when using the service arm 30 for securing the distance from the mounting portion to the mooring position of the service wire 4, it can be used, Can be used in various situations.

Furthermore, since the lead-in mooring fitting 1 is formed by bending a single metal plate 1a cut into a predetermined shape (see FIG. 5) as described above, it can be manufactured very easily and at a low cost. can.

Although the embodiments of the present invention have been described above, the specific configuration is not limited to the above-described embodiments. Included in the invention. For example, although the case in which two retraction arms are attached has been described, the present invention is not limited to this, and one retraction arm may be attached.
