Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a building exterior wall support device for an overhead service line, which is used when the exterior wall of the building is used as the first support point for the service line, mainly when the high voltage overhead power distribution line is brought into the building. It is something.

PRIOR TECHNOLOGY When the entry angle of the service line is approximately 90 degrees with respect to the building wall surface, a support body is simply fixed along the wall surface, the service line is held in place by an insulator attached to the support body, and the service line is placed around the edge. However, if the entry angle has to be steep, the above method will cause the lead-in wires near the lead-in point to be too close together, which may cause electrical troubles such as voltage drop. A frame configured to face directly (with a 90-degree wire entry angle) is attached to the building wall to maintain the distance between the wires.

Problems that the invention aims to solve: Generally speaking, it is rare for power poles (service poles) or No. 1 poles to be installed at positions where the entry angle of the service line is approximately 90 degrees, and for this reason, the entry angle of each site is Applicable frame members must be prepared.

Therefore, the number of types of parts inevitably increases, and there is waste in all aspects such as inventory management and transportation.

Means for Solving the Problems The present invention was devised for the purpose of eliminating the conventional drawbacks and providing a device that can accommodate various lead-in line entry angles.To achieve this purpose, the upper frame, A U-shaped main frame consisting of a lower frame and a vertical frame, and a support frame whose tip is rotatably pivoted to the middle part of the vertical frame of the main frame, each of which is installed by protruding from the building exterior wall at the base end. The seat is tightened with bolts so that it can rotate when loosened, and insulators are attached to appropriate positions on the main frame and support frame.

Embodiment The drawing shows an embodiment of the building exterior wall support device for overhead service lines according to the present invention, in which 1 is a main frame;
This is a U-shaped body in which the tips of an upper frame 2 and a lower frame 3 are welded to a vertical frame 4 via a connecting piece 5.

Reference numeral 6 denotes a connecting frame fastened to the middle part of the vertical frame 4 of the main frame 1 with bolts 7 and nuts 8. The support pieces 6b, 6b of the connection frame 6 are
The tip of the support frame 9 is engaged between the support frames 6b and is rotatably connected by bolts 10 and nuts 11.

The support frame 9 consists of a front frame 9a attached to the vertical frame 4 of the main frame 1 via a connecting frame 6, and a rear frame 9b having the front end 9a engaged with the front frame 9a.
Match the appropriate through holes 12, 12, ... provided in b with each other, and tighten the bolt 13 and nut 14.
By fixing them to each other, the length can be adjusted telescopically.

15 in the figure is a mounting seat configured by protruding a pair of mounting members 15b, 15b on one side of a board 15a,
Between the mounting pieces 15b and 15b of this mounting seat 15,
When the upper and lower frames 2 and 3 of the main frame and the bases of the support frame 9 are engaged and loosened by the bolts 16 and nuts 17, tighten them so that they can rotate, and the upper and lower frames 2 and 3 and the support frame 9 are Boards 15a, 15 of mounting seats 15, 15, 15 attached to each base of frame 9
a, 15a are fixed to the wall surface W of the building with screws 18.

Further, numerals 19, 19, . . . are through holes for attaching the insulators 20, and the through holes 1 provided in the support frame 9
2 has the same function as this through hole 19.

Therefore, the main frame 1 and the support frame 9 are rotated relative to each other around the bolt 7 so that the entrance angle of the lead-in line a to the main frame 1 is approximately 90 degrees. The apparatus of the embodiment is obtained by setting the angle and fixing the mounting seats 15 attached to the respective bases to the wall surface W of the building with screws 18.

Note that 21 in the figure is a switch with a ground fault protection device supported by the upper frame 2 of the main frame 1, and 22 is a support arm for holding the electric wire led out from the switch 21.

Effects of the invention Since the present invention has the above-mentioned configuration, it can be installed on the exterior wall of the building by appropriately setting the relative angle between the main frame and the supporting frame. The aforementioned drawbacks of the example can be avoided.
