Description

[Detailed Description of the Invention] [Technical Field] - The present invention relates to a structure for mounting a flat antenna on a roof, and more specifically, to a structure for mounting a flat antenna installed on a tiled roof for receiving satellite broadcasting, etc. be.

[Background technology] In recent years, satellite broadcasting using geostationary satellites has been carried out, and microwaves (12 GHz band) are used. As shown, a parabolic antenna 20 is used. Since the parabolic antenna 20 has a complicated shape and mounting structure, there is a problem that the cost is high.

Furthermore, since the parabolic antenna 20 is bowl-shaped, it is susceptible to wind pressure, and the supporting device such as the ball 21 becomes large in order to withstand winds like a typhoon, so a large installation space is required. In addition, there are problems in that the construction work is troublesome, and the parabolic antenna 20 is conspicuous from the outside and spoils the appearance of the house. For this reason, it has been considered to use a planar antenna with a simple shape and relatively high sensitivity, and it is desirable to install the antenna on a roof where it is not affected by adjacent buildings. However, since microwaves are highly directional, a fixed structure using a fixed wire, as has been conventionally used for very high frequency antennas and extremely high frequency antennas, may cause the antenna to shift, causing the radio waves to There is a problem in that the signal cannot be received with sufficient strength. Therefore, a fixing structure that does not cause positional displacement is desired.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and its main purpose is to accommodate the planar antenna in the casing and to fix the casing to the roof. The purpose is to fix the flat antenna to the roof so that it does not shift by fixing it to the roof with bolts, and the other purpose is to fix the flat antenna to the roof so that it can be installed even if the tiles have different dimensions. The objective is to provide a mounting structure for the.

[Disclosure of the Invention 1 (Example 1) In Example 1, a flat antenna 2 is attached to an ordinary roof tile 1a.
Here is an example where is fixed. As shown in FIG. 5, each of the planar antennas 2 is housed in a casing 3 constructed by combining a thin box-shaped body 11 and a cover 12. As shown in FIG. 2, the body 11 has elongated holes 4 formed at four corners of the bottom plate, and the elongated holes 4 are formed long along one side edge of the bottom surface of the body 11. cover 12
is made of synthetic resin with high radio wave transparency, such as acrylic resin. By housing the planar antenna 2 in the casing 3 in this way, the planar antenna 2 is not exposed to the outside air, and is therefore not affected by the wind, and can also prevent performance deterioration due to salt damage, etc. This improves durability.

As the planar antenna 2, as shown in FIG. 5, a pair of side-looking circularly polarized microstrip line planar antennas are used. Since microwaves have strong directivity, each planar antenna 2 can be adjusted in elevation angle (inclination angle in the vertical direction) and azimuth angle (inclination angle in the horizontal direction). The elevation angle adjuster 22 and the azimuth angle adjuster 23 are designed to finely adjust the inclination angle of each planar antenna 2 as the plane moves forward and backward. This plane? The antenna has so-called side-looking characteristics, and even if the elevation angle and azimuth angle are adjusted, the planar antenna 2
There is no need to make the angle too steep. The peripheral plane of the antenna 2 is attached to the body 1 by means of bolts (not shown).
The frame 24 is attached to a pair of seven frames 24 fixed to the frame 1 via an elevation angle adjuster 22 and an azimuth angle adjuster 23, and a bolt attachment hole 25 is formed in the frame 24. The outputs of the two-handed antenna 2 are combined by a combiner 26, and the output of the combiner 26 is taken out as an antenna output via a BS converter 27.

On the other hand, as shown in FIGS. 1 and 4, a mounting bracket 5a having a bolt 6 projecting upward is fixed to the roof.

The mounting bracket 5a has an upright piece 17 rising upward from a mounting piece 16 fixed to a roof base 15 such as a roof board, and a horizontal piece 18 curved along the roof tile 1a at the upper end of the upright piece 17. The vertical piece 19h is extended from the tip of the horizontal piece 18.
The Nibolt fixing piece 20 is integrally formed in a protruding shape.

A bolt 6 projecting upward is fixed to the upper surface of the bolt fixing piece 20 by a method such as welding. The horizontal piece 18 is easily inserted into the roof tile 1a that overlaps the roof tile 1a vertically in the width direction of the roof tile 1a adjacent to each other in the width direction of the roof tile 1a.
The Pol F fixing piece 20 is exposed on the surface side of the roof tile 1a. The roof base 15 is formed by laminating a reinforcing plate 33 on the top surface of a roofing board 31 via a roofing 32, and the mounting piece 16 of the mounting bracket 5a is fixed to the roof base 15 with screws 34. A sealing material 35 such as a sheet-shaped butyl rubber is interposed between the mounting piece 16 and the roof base 15 to protect the portion where the screw 34 is inserted from rain.

A reinforcing plate 33 is provided on the roof base 15, and it is preferable that the screws 34 be screwed into a structural member such as a rafter or a main building so that the fixing strength of the mounting bracket 5a can be increased.

In order to fix the planar antenna 2 on the roof, the mounting bracket 5a is attached to an appropriate location on the roof, the bolt 6 protruding from the roof tile 1a is inserted into the long hole 4 of the casing 3, and the washer 36 is inserted into the long hole 4 of the casing 3. By screwing the nut 7 into the bolt 6 via the bolt 6, the body 11 can be fixed to the roof tile 1a. Here, the casing 3 is installed so that the direction of the elongated hole 4 coincides with the width direction of the roof tile 1a, and the bolts 6 are attached due to the dimensional difference in the width direction of the roof tile 1a.
Even if the mounting intervals of the tiles are different, the dimensional difference can be absorbed within the length of the elongated hole 4, and it can be installed on roof tiles 1a of various sizes using the casing 3 of the same standard. It is possible. Regarding the slope direction of the roof, the mounting position of the mounting bracket 5a can be freely set regardless of the dimensions of the roof tile 1a. Since the planar antenna 2 is fixed to the body 11 with a bolt inserted through the bolt attachment hole 25, the planar antenna 2 can be fixed to the roof by fixing the casing 3 to the roof. A cover 12 is fitted onto the body 11, and a sixth
As shown in the figure, a planar antenna 2 is housed within a casing 3.

The planar antenna 2 fixed on the roof as described above has an appearance as shown in Fig. 11, and not only has a high fixation strength to the roof, but also has a thin structure, so the casing 3 itself is protected against the influence of wind. It is difficult to receive wind, and its strength against wind is extremely high. Moreover, since the casing 3 is thin, it is not very noticeable in appearance and does not spoil the aesthetic appearance.

(Example 2) In Example 2, a flat tile 1 such as an asbestos slate tile
The mounting structure in b is shown. As shown in FIGS. 7 and 8, the mounting bracket 5b is formed into a flat plate shape, and has a bolt 6 projecting upward from one end thereof in the operator's direction.
A hook portion 40 is formed at the other end in the technique direction. This mounting bracket 5b connects one end where the bolt 6 is provided to the flat tile 1.
b, and the other end on which the hook portion 40 is formed is overlapped with the lower surface side of the flat tile 1b above it, and the hook portion 40 is hooked on one nail 41 that fixes the flat tile 1b. It is fixed to the roof. One end of the mounting bracket 5b on which the hook portion 40 is provided is formed into a thin blade shape so that it can be easily inserted between the vertically overlapping flat tiles 1b. In this way, Example 1
Similarly, the bolt 6 of the mounting bracket 5b fixed on the roof can be inserted into the elongated hole 4 of the casing 3, and the casing 3 can be fixed using the nut 7.

(Example 3) In Example 3, a mounting structure for fixing to a tile rod roof is shown. As shown in FIGS. 9 and 10, the mounting bracket 5c
is formed in a substantially F-shape extending over the tile bar 1c, and a bolt 6 is provided protruding from the upper surface of the horizontal piece 51. Mounting bracket 5
A hinge 53 is screwed into one leg piece 52 of c.
As shown in FIG. 10, the mounting bracket 5c is straddled over the tile bar 1c, and the hinge 53 is tightened.
If the tip of the tile rod 1c is pressed against the side surface of the tile rod 1c, the mounting bracket 5c
between the other leg piece 52 and the tip of the butterfly screw 53.
is clamped, and the mounting bracket 5c is fixed to the tile bar 1c. By fixing the casing 3 in which the planar antenna 2 is housed, the planar antenna 2 can be fixed on the roof.

[Effects of the Invention] As described above, the present invention has a structure in which a planar antenna is fixed on a tiled roof, the planar antenna is housed in a casing having radio wave transparency, and the bottom plate of the casing has a A long elongated hole is formed along the roof, and a mounting bracket with a bolt protruding upward is fixed to the roof with the bolt protruding upward.The bolt is inserted through the elongated hole and is screwed onto the tip of the bolt. The bottom plate of the casing is held between the matching nuts and the mounting bracket, so by fixing the casing housing the planar antenna to the bolts fixed to the roof, the planar antenna can be fixed on the roof without shifting. In addition, a long slot is formed in the casing along the width direction of the tile, and a bolt protruding from the mounting bracket fixed to the roof is inserted into the slot to attach the casing to the roof. Since it is fixed, the position can be adjusted within the range of the elongated hole even if the inside dimensions of the tiles are different, and the planar antenna has the advantage of being able to be fixed to tiles of various sizes using casings of the same standard. .
