Description

[Detailed explanation of the invention] (a) Industrial application field This invention is used for roofs in which a parabolic antenna installation frame, solar water heater, etc. of a solar system is fixed on the roof tiles of a building or on the tile rods of a metal roof. The present invention relates to an upper fixing device, and particularly to a roof fixing device that has a simple structure, can be firmly fixed, and is completely waterproof.

(b) Conventional technology Conventionally, in order to install a solar water heater, etc. of a solar system on the slope of a building's roof, it was tied to a wire or rope, and the other end of the wire or rope was fixed to a protrusion on the roof. However, it required extra wires, ropes, etc., was expensive, and was not strong enough. Also, it was impossible to attach it directly to the roof tiles.

(c) Purpose This invention was newly developed to improve the above problems, and has a simple structure that allows fixed objects such as parabolic antenna installation frames and solar water heaters for solar systems to be fixed to tiles. The main purpose of this invention is to provide a roof fixing device that can be easily fixedly installed on the roofs of buildings, etc., has a strong fixation, and has a good waterproof effect.

(D) Structure The present invention is a roof fixing device comprising an elastic umbrella-shaped waterproof cap with a flared shape, a hanger bolt, a nut, a washer, etc. A waterproof protrusion is formed, and the umbrella-shaped waterproof cap is press-fitted into the abdomen of the hanger bolt, and a nut is further screwed from above, and the object to be fixed is fixedly installed on the roof with a washer or the like interposed. This is a roof fixture featuring:

(E) Embodiment Figure 1 is an exploded perspective view of the roof fixture according to the present invention, Figure 2 is an enlarged partially cutaway front view of an umbrella-shaped waterproof cap, and Figure 3 is a partially cutaway view of the roof fixture. A perspective view showing installation on the roof, Figure 4 is a reduced sectional view of the roof fixture fixed to the tile roof, Figure 5 is a reduced sectional view of the roof fixture fixed to the tile roof, and Figure 6 FIG. 7 is a perspective view in which a roof fixture is used to securely install a parabolic antenna mounting frame, and FIG. 7 is a perspective view in which a roof fixture is used to securely install a solar water heater in a solar system.

In FIG. 1, reference numeral 10 denotes a hanger bolt, which is formed from a lower wood threaded portion 11, a rod-shaped abdomen 12, and an upper bolt portion 13. This hanger bolt 10 has an umbrella-shaped waterproof cap 20 made of elastic rubber or the like that is press-fitted into its abdomen 12, and a nut 30 is screwed from above, and a washer or wire connector 40 and a spring washer are screwed together. The ear 50 is inserted and tightened with a nut 60.

The umbrella-shaped waterproof cap 20 clearly shown in FIG.
3 are integrally formed, and the lower opening 24 is formed to become gradually thinner toward the diagonally lower lower end.

Figure 3 shows the situation when attaching the roof fixture A to a predetermined location on the roof. A hole D is pre-drilled with a concrete drill at the intersection of the roof purlin B and the rafter C. Attach by screwing in the wood screw part 11 of the roof fixture A. On this occasion,
In advance, screw the nut 30 onto the bolt part 13 of the hanger bolt 10 all the way to the end, screw the wood threaded part 11 into the hole D a little, and then turn the nut 30 strongly with a spanner or the like, the hanger bolt 10 will rotate as a whole, so The wooden screw part 11 is screwed into the intersection of the main building B and the rafter C, and the roof fixture A is attached and fixed.

FIG. 4 shows an example in which the roof fixture A is attached to a tiled roof. However, although Fig. 4 should actually be shown tilted, it is shown horizontally for convenience.
Drill a hole D in the tile E, and at that time insert the roof board N and the rafters C.
Drill a hole D up to the hole D, screw the wood threaded portion 11 of the hanger bolt 10 of the roof fixture A into the hole D, turn the nut 30 with a spanner in the manner described above, and install the roof fixture A as shown in the figure. In this case, the lower part of the umbrella-shaped waterproof cap 20 comes into close contact with the slope of the tile E due to its elasticity. F is the caulking agent filled in the hole D, and G is the leg of the parabolic antenna installation frame. Note that Y indicates the roof soil for securing the tiles E.

Figure 5 shows an example in which a roof fixture A is attached to a tile rod roof. A hole D is drilled in the tile rod H in advance, and a hole D is further drilled to the roof board N and rafters C, and the hole D is placed on the roof. Wood threaded part 1 of hanger bolt 10 of upper fixture A
1, turn the nut 30 with a spanner, and install the roof fixture A as shown in the diagram. In this case as well, the lower part of the umbrella-shaped waterproof cap 20 has a tile bar H due to its elasticity.
adheres closely to the surface.

Figure 6 shows leg G of the parabolic antenna installation stand.
The roof fixing device A is attached to the roof,
The umbrella-shaped waterproof cap 20 is press-fitted into the abdomen 12 of the hanger bolt 10, the nut 30 is screwed onto the bolt part 13, and the washer 7 is screwed and fixed onto the roof.
Insert the upper part of the hanger bolt 10 into the long hole J of the leg G of the parabolic antenna installation frame from below through the bolt 0, and then insert the nut 60 into the bolt part 13 of the hanger bolt 10 through the washer 70 and the spring washer 50. The legs G are fixed by screwing together and tightening.

Figure 7 shows a solar water heater K of the solar system fixedly installed on the roof using roof fixtures A, and shows four roof fixtures A, A,
One end of the wire L is tied to the wire connectors 40 of A and A, and the other end is tied to the fixture M of the solar water heater K, so that the solar water heater K is fixedly installed on the roof.

In this embodiment, the umbrella-shaped waterproof cap 2
Two waterproof protrusions 2 are provided on the inner surface of the cylindrical insertion portion 21 of 0.
2 and 23, however, one or more waterproof protrusions may be provided.

In addition, in this embodiment, the explanation was limited to the parabolic antenna installation frame and the solar water heater of the solar system, but the object is not limited to this, and any object can be fixed to the roof. The uses of fixtures are extremely wide.

(f) Effects As mentioned above, the present invention is an elastic umbrella-shaped waterproof cap that is press-fitted into a hanger bolt. In addition to being able to cover the cap, the waterproof ridges are provided on the inner surface of the cylindrical insertion part of the umbrella-shaped waterproof cap, so the waterproof effect is outstanding.In addition, the umbrella-shaped waterproof cap is composed of a hanger bolt, washers, nuts, etc. It has a simple structure, is easy to handle, has excellent workability, can be provided at low cost, and can be fixed firmly.
