Description

[Detailed description of the invention] (Industrial application field) This invention is used to fix the base of a tension wire for attaching rooftop installations such as television antennas, wireless antennas, solar water heaters, etc. on the roof. Regarding metal fittings.

(Prior art) Generally, when installing a TV antenna etc. on the roof, multiple tension wires are used.
The base of each tension wire is fixed to a wooden part such as a rafter at the eaves. As shown in FIG. 6, conventionally, nails have been used as fixing fittings for fixing the base of each tension wire to rafters or the like.

(Problem to be solved by the invention) However, when a nail is used as a metal fitting for fixing the base of the tension wire as in the past, the tip of the roof tile or eaves gutter is more likely to be damaged than the tip of the rafter into which the nail is driven. Because the wire protrudes outward, the base of the tension wire comes into pressure contact with the protruding tip of the roof tile, and therefore, when the antenna receives strong wind pressure, the pressure contact part of the tension wire presses against the roof tile. There were problems with lifting it upwards and damaging the eaves and gutters.

Another problem is that nails have a weak fixing force and tend to loosen the tension wire or fall off.

(Means for solving the problem) The present invention was made with the purpose of solving the above-mentioned problems, and to achieve this purpose, the present invention uses a fixed substrate that can be fixed to a rafter, etc. and a detour fitting curved in an abbreviated shape so as to bypass a protruding part of a roof tile, etc., and the fixing board has a bearing part that rotatably supports the short end of the detour fitting. In addition, the long side end of the detour fitting is provided with a wire connection portion.

(Function) In the metal fitting for fixing the base of a wire for installing on a roof such as an antenna of the present invention, a fixed board that can be fixed to a rafter, etc. is attached in an abbreviated shape so as to bypass the protruding parts of roof tiles, eaves gutters, etc. By providing a curved detour metal fitting, the base of the tension wire can be connected and fixed above the roof tile without contacting the roof tile or eaves gutter, and therefore has a lifting effect on the roof tile or eave gutter. It will be possible to eliminate all the negative effects such as

Further, due to the strong fixing by the fixing substrate and the buffering effect of the oval-shaped detour metal fittings, the fixing force to the rafters etc. is strong, and the durability can be greatly improved.

In addition, since the fixed board is equipped with a bearing that rotatably supports the short end of the detour metal fitting, the detour metal fitting can rotate freely in the horizontal direction, and therefore the fixing location of the fixed board, the antenna, etc. Regardless of where the detour is installed, the detour metal can always be oriented in the direction in which the wire is stretched, so it is possible to reliably prevent the generation of torsional stress on the detour metal that is curved in an abbreviated shape. The durability of the bypass fitting is improved.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the embodiment will be explained.

As shown in FIGS. 1 and 2, the base fixing fitting A of the wire for installing on the roof such as an antenna in this embodiment mainly consists of a fixing board 1, a detour fitting 2, and a connecting fitting 3. It is provided as a configuration.

The detour metal fitting 2 is a metal fitting for positioning the wire connection part on the upper part of the roof tile K, and in this embodiment, it is curved in an abbreviated shape so as to bypass the protruding parts of the roof tile K, eaves gutter D, etc. At the same time, the detour fitting 2
The long side end portion 20 is further bent obliquely in the same direction as the bending direction of the short side end portion 21.

The connecting fitting 3 includes a long side end 2 of the detour fitting 2.
In this embodiment, the free end side of the connecting fitting 3 is provided with a wire connecting hole 30 that serves as a wire connecting portion.

Next, the operation of this embodiment will be explained.

This embodiment is configured as described above, so
As shown in FIGS. 1 and 2, first, the fixed board 1 is fixed to the end surface of the rafter T at the eaves using a total of eight nails 15, and then the bearing part 12 of the fixed board 1 is fixed.
By curving the stopper piece 14 along the curved bottom surface of the detour metal fitting 2 with the short end 21 of the detour metal fitting 2 rotatably inserted from below, the detour metal fitting 2 can be prevented from falling out. It becomes a prevented state. In this state, the base of the tensioning wire W is connected and fixed to the wire connection hole 30 of the connecting fitting 3, so that the base of the tensioning wire W is connected and fixed to the rafter T via the base fixing fitting A. becomes.

As explained above, in the case of the metal fitting A for fixing the base of the wire for extending roof-mounted items such as antennas in this embodiment, the fixing board 1, which can be fixed to rafters T, etc., is used to attach roof tiles K, eaves gutters D, etc. By providing the bypass fitting 2 curved in an oval shape so as to bypass the protrusion, the base of the tension wire W can be connected and fixed above the roof tile K without coming into contact with the roof tile K or eaves gutter D. Therefore, it becomes possible to eliminate all adverse effects such as lifting effects on roof tiles K and eaves gutters D.

Further, due to the strong fixing by the fixing substrate 1 and the buffering effect of the oval-shaped detour fitting 2, the fixing force to the rafter T etc. is strong, and the durability can be greatly improved.

In addition, the short side end 2 of the detour fitting is attached to the fixed board 1.
Since the detour fitting 2 is provided with the bearing part 12 that rotatably supports the antenna 1, the detour fitting 2 can freely rotate in the horizontal direction. Since the detour fitting 2 can always be oriented in the direction in which the wire W is stretched,
Generation of torsional stress on the detour fitting 2 curved in an oval shape can be reliably prevented, and the durability of the detour fitting 2 is therefore improved.

In addition, in the embodiment, a connecting fitting 3 is connected to the long side end 20 of the detour fitting 2 in a vertically movable state, and a wire connecting hole 3 is connected to the free end side of the connecting fitting 3.
By providing 0, the wire connecting portion can always be oriented in the direction in which the wire W is stretched, regardless of the height of the antenna or the like.
