  However, the above Patent Document 1 invention and Patent Document 2 invention have the following problems. In order to install a stand for installing a photovoltaic power generation device in a state where the roofing material was sown on the roof, it was necessary to remove the roofing material once and install metal fittings and support devices on the exposed field ground .

Furthermore, in the method described in Patent Document 1, the roof tile is once removed, the metal fittings are installed, and the roof tile that has been returned to the original cannot be nailed, so that the fixing strength of the roof tile is lowered. In addition, there is a problem of poor workability such that the roof material needs to be processed so that no gap is generated in the roof material due to the metal fittings.

On the other hand, in the method described in Patent Document 2, the roof material removed by this construction method becomes waste as it is without being restored, and generation of waste is forced. In addition, the amount of waste is proportional to the number of support devices and metal fittings applied to the roofing material, and in some cases, costs such as a large amount of processing costs are required. In addition, metal roof tiles that are about the size of one roofing material are required, the support device itself becomes large, and handling is troublesome. In other words, the conventional technique requires the work of removing the roof material, and there is room for improvement in terms of workability, material cost, generation of waste, and the like.

  In view of the above, an object of the present invention is a method of attaching a metal fitting for installing an installation on a roof to a roofing material, which does not require the work of removing the roofing material, and simplifies the necessary members. An object of the present invention is to provide a support structure and a support method for a rooftop installation and a support tile which are easy and cost-effective.

  In order to solve the above problems, the present invention provides a roof tile having a through hole in the head, a first metal fitting inserted into the through hole and locked to the roof tile, In order to fix the support frame to the roof tile, a structure for supporting the installation object on the roof made of the second metal member locked to the first metal member is provided.

  By adopting the above means, it is possible to directly hook the first metal fitting to the roof tile through the through hole provided in the roof tile, and further, the second metal fitting is locked to the first metal fitting on the roof. The installation object or its support frame can be fixed on the roof tile via the first metal fitting and the second metal fitting.

In the present invention, in order to more effectively demonstrate the above-described operation and the effects described below, a hook portion that is locked to the back surface of the roof tile is formed at the base end portion of the first metal fitting, A means is adopted that is an L-shaped metal fitting in which a screw part into which a nut is screwed is provided. By adopting this means, the second metal fitting can be fixed by hooking the first metal fitting behind the roof tile and screwing the nut. In addition, it is also possible to stabilize the catch on the back of the roof tile by flattening at least a portion of the base end portion that contacts the back surface of the roof tile.

Furthermore, in the present invention, for the same purpose, a means is adopted in which a gap between the through hole and the first metal fitting inserted therethrough is sealed. By inserting or filling a packing material and / or a caulking agent and an adhesive that match the shape of the through hole into the gap, water flowing down the surface of the roof tile does not enter the ground from the through hole.

  In addition, in the present invention, by adopting a means in which the through hole is provided in an overlapping portion of the roof tile and another roof tile that is laid below the roof tile, water should be through. Even if it breaks through the seal applied to the roof and leaks into the back of the tile, it will fall onto the roof tiles that are laid down below, so that water will not leak into the field. Therefore, the waterproof performance can be sufficiently ensured by sealing the gap and providing the through hole at a position where the roof tile is wound downward. Further, by filling the overlapping portion with a caulking agent or an adhesive, the roof tile and the other roof tiles placed under the roof tile can be fixed to each other, thereby improving wind resistance and earthquake resistance.

Further, the support structure for an installation on the roof according to the present invention includes a step of forming a hole in the roof tile, a step of filling the through hole with a caulking agent, and a first fitting being inserted into the through hole. This method can be realized by a method including a step, a step of inserting a packing material into the through hole, and a step of locking the installation object on the roof to the first metal fitting and fixing it with the second metal fitting.

  By adopting the above method, it is possible to obtain an optimum structure without losing one or more performances in terms of workability, waterproofness, wind resistance or earthquake resistance.

In the above structure and method, a through-hole for allowing a metal fitting for locking an installation object on a roof to pass through a portion of the roof of the main body of the roof tile that overlaps with the bottom of the roof tile placed under the roof tile. This is only possible if there is a roof tile with a certain structure. The terms roof tile, tile or tile body used in the specification according to the present invention have substantially the same technical meaning, and the main part of the tile must be called to modify the roof tile. If not, the term tile body is sometimes used.

  The present invention exhibits the effect that, when installing an installation on the roof tile on the roof tile, there is no work for removing the roof tile, and the construction can be easily performed and the cost is excellent with almost no waste generated. .

Example 1
A first embodiment of the present invention will be described. As shown in FIGS. 1 to 11, the fixing structure A of the present invention is configured by a member group of a first metal fitting 1, a nut 4, a second metal fitting 5, a packing material 6, a caulking agent 7, and a roof tile 9. . First, these member groups will be described.

As shown in FIG. 1 to FIG. 2 and FIG. 14, the first metal fitting 1 is composed of a rod-shaped body whose side surface is L-shaped, and is substantially in surface contact with a back surface 92 of a roof tile main body 9 to be described later on its base end portion 2. It has a flat portion 22 processed flat. The total length of the base end portion 2 is larger than the diameter of the through hole 8 provided in the head of the tile main body 9 and is set to 15 to 25 mm as an example so that the base end portion 2 can be appropriately hooked to the tile back 92 side.

The distal end portion 3 is substantially perpendicular to the proximal end portion 2, has a screw portion 32 near the distal end surface 31, and has a structure in which the nut 4 is screwed to the screw portion 32. The total length of the front end portion 3 is equal to or higher than the height of the overlapping portion between the head of the tile main body 9 and the bottom of the other tile main body that is placed below the tile main body 9. It is a grade which can project more than it, and also projects from the roof tile 91 after construction and does not impair the appearance.

Since the first metal fitting 1 is basically constructed in a place exposed to the outdoors, the material is, for example, austenitic stainless steel (for example, SUS304J3), and one having corrosion resistance and strength is selected. . As the material diameter of the first metal fitting, a diameter of 3.9 to 5.2 mm (screw diameter of 4.5 to 6.0 mm) is selected as an example in order to enable insertion into the through hole 8.

As shown in FIG. 3 to FIG. 6 and FIG. 17, the second metal fitting 5 is composed of a lower portion 51, a support portion, which is formed by bending a substantially flat plate material at two locations and making the side surface substantially U-shaped or inverted U-shaped. 52 and an upper portion 53, a screw hole 54 for passing the first metal fitting 1 is provided in the lower portion 51. An elongate hole 55 that can fix the mount is provided. In addition, the lower portion 51 and the support portion 52 are in a substantially right angle relationship, and the support portion 52 and the upper portion 53 are configured so that the return gradient of the roof tile 9 (the gradient of the field ground) is such that the upper portion 53 is substantially parallel to the field ground (not shown). Taking into account the difference between the roof tile 9 and the slope of the tile surface 91), the relationship is somewhat obtuse, and the angle is selected as 92 to 100 degrees as an example.

Since the second metal fitting 5 is constructed on the roof tile 9 and directly affected by the outdoor environment, it is required to have excellent durability, corrosion resistance, salt resistance, and the like. A stainless steel (for example, SUS304) is selected. The diameter of the screw hole 54 is set such that the tip 3 of the first metal fitting 1 can be inserted so that the first metal fitting 1 can be passed, and a diameter of 5 to 8 mm is selected as an example. The thickness of the second metal fitting 5 is, for example, about 3 mm so that the strength can be secured even with a simple shape.

As shown in FIGS. 7 to 8 and 16, the packing material 6 prevents water from entering the through hole 8 opened in the roof tile body 9, and also provides a clearance between the through hole 8 and the first metal fitting 1 inserted therein. It works to eliminate (play). The shape is a taper on the roof back 92 side during insertion in order to prevent the water stoppage and the return of the first metal fitting 1 to the tile surface 91 side when the nut 4 is screwed to the first metal fitting 1, It is desirable that it is substantially T-shaped. The shape of the packing material may be substantially cylindrical in accordance with the through hole 8 and the first metal fitting 1 (FIGS. 7 and 8 show only the packing material having a substantially cylindrical shape. Not)

The outer diameter of the packing material 6 is 10 to 13 mm, which is the same as the diameter of the through hole 8 or slightly smaller than that, so that the packing material 6 can be easily inserted into the through hole 8. The inner diameter is approximately the same as the screw diameter of the first metal fitting 1 so as to be easily adapted to the first metal fitting 1, and is set to 4.5 mm to 6.0 mm as an example. As an example, the length is selected to be 12 to 14 mm so as to be approximately the same as the thickness of the roof tile body 9. In consideration of the influence of a silicon-based caulking agent, which will be described later, a vinyl chloride-based material is selected as an example.

As shown in FIG. 13 a, the caulking agent 7 prevents the intrusion of water into the through-holes 8 as with the packing material 6, and bonds the upper and lower roof tiles 9 to each other by taking advantage of the adhesive property. It works to improve seismic performance. As the material, it is desirable to select a material having high durability, water-stopping property or adhesiveness such as silicon-based, modified silicon-based, or urethane-based materials.

In addition, as shown in FIG. 13b, the adhesive 71 is poured into the roof tile to bond the roof tile and the roof tile to be sown downward to prevent water from entering the roof tile, and against strong winds and vibrations. Also works to prevent the tiles from lifting and shifting. As a material, a material that forms a one-component or two-component polyurethane foam is used as an example so that a space between the roof tile and the roof tile to be laid down can be filled over the entire space. In addition, by forming a foam, the area which adhere | attaches the circumference | surroundings of the space between the roof tile 9 and the roof tile 9 laid down below becomes large, and adhesive strength can be improved.

  As shown in FIG. 9 to FIG. 11, the roof tile 9 of the present invention is a tile having a substantially flat surface, which is generally used as an F-shaped tile, and penetrates a portion near the head of the roof tile 9. A hole 8 is provided. The through hole 8 has two or more per roof tile, and the first metal fitting 1 is inserted into each of the roof tiles so that the above-mentioned second metal fitting 5 is sufficiently and stably fixed. Yes. Further, the roof tile 9 has a thicker head than the tile main body, and there is some space between the roof tile 9 and the overlapping portion of the roof tile 9 that is laid down below. The first metal fitting 1 can be inserted through the through-hole 8, and further, the caulking material 7 or the adhesive 71 can be filled.

Next, a construction method for attaching the above-described member group to the roof tile will be described. First, as shown in FIG. 12, the roof tile 9 to which the second metal fitting 5 is fixed is selected, and the second roof tile 9 of the roof tile 9 on the eaves side is located at the position where the second roof tile 9 exists. The position where the through hole 8 is opened is marked with reference to the screw hole 54 provided in the metal fitting 5. According to the marking position, a hole is made using a drill or the like, and this is defined as a through hole 8. At this time, it is more preferable to use a jig that can make only the roof tile 9 in the drill body so as not to damage the other roof tile 9 in which the drill blade is wound downward.

  Subsequently, as shown in FIG. 13a or FIG. 13b, the caulking agent 7 or the adhesive 71 is filled into the roof tile from the through hole 8 provided by the above process. The filling amount may be such that the space of the overlapping portion between the through hole 8 and the roof tile 9 below the through hole 8 is filled.

  Subsequently, as shown in FIG. 14, the first metal fitting 1 is inserted into the through hole 8 filled with the caulking agent 7 or the adhesive 71. Since the base end portion 2 of the first metal fitting 1 is longer than the diameter of the through hole 8 and it is impossible to insert the base end portion 2 parallel to the roof tile 9, Insertion adds a rotational motion to the first metal fitting 1. First, as shown in FIG. 15 a, the distal end portion 3 and the roof tile body 9 are made parallel, and the base end face 21 is inserted into the through hole 8. Next, as shown in FIGS. 15 b and 15 c, the distal end surface 31 is inserted while rotating so as to draw an arc on the roof tile 91 side according to the insertion depth of the base end surface 21 into the through hole 8. By this rotation operation, the base end portion 2 can reach the roof tile 92 side through the through hole 8.

Then, even if the first metal fitting 1 inserted into the through-hole 8 is pulled vertically upward with respect to the roof tile 9 as shown in FIG. There is nothing. When taking out the 1st metal fitting 1 after inserting in the through-hole 8, it is possible by the reverse procedure of the said rotation operation | movement. The first metal fitting 1 is inserted after filling the caulking agent 7 or the adhesive 71. Since the caulking agent 7 or the adhesive 71 is a semi-solid elastic body at the beginning of filling, the first metal fitting 1 is inserted. It is not affected by the insertion of 1.

  Further, as shown in FIG. 16, the packing material 6 is inserted from the tip of the first metal fitting 1. The packing material 6 may be inserted into the through hole 8 after the first metal fitting 1 is attached to the distal end portion 3 in advance. Then, as shown in FIG. 17, the first metal fitting 1 is attached to the screw hole 54 of the second metal fitting 5. In the drilling step, since the through hole 8 is provided in advance with reference to the position of the screw hole 54, it is only necessary to attach the screw hole 54 in accordance with the first metal fitting 1.

  Finally, as shown in FIG. 18, the nut 4 is tightened from the tip of the first metal fitting 1. At this time, a flat washer, a spring washer, or a double nut (not shown) is used together for the purpose of preventing the second metal fitting 5 from being damaged during tightening and preventing the loosening of the nut due to vibration of the roof tile 9 caused by wind or the like. May be.

  As shown in FIG. 19, the construction of the member group described above, the installation object on the roof or its installation base (in FIG. 19, only the mounting bolt 41 which is one element of the base is drawn) It can be fixed on the roof tile 9 via the one metal fitting 1 and the second metal fitting 5. In actual installation work, as shown in FIG. 20, the present invention is attached to the roof tile 9 by a necessary amount by the above-described construction method, and bolts 41 and the like are attached to the long holes 54 of the second metal fitting 5. What is necessary is just to attach the said mount frame or installation on a roof. When the structure of the present invention such as repair or replacement is removed from the roof tile 9, it is possible to perform the above-described processes in the reverse order. Regarding the disaster prevention performance, the fixing structure A of the present invention can exhibit performance against wind pressure and vibration by fixing the caulking agent 7 or the adhesive 71 to the roof tile 9.

  In addition, this invention is not limited to the above-mentioned favorable example, In the range which does not deviate from the fundamental technical idea, it can change suitably. Although the shape of the first metal fitting 1 in the present invention is a substantially right-angled L shape, for example, the corner between the base end portion and the tip end portion may be chamfered into a square surface or a round surface, or the base end portion May be bent in an arc shape downward. In addition, the material, size, and number of the members constituting the present invention can be changed in arrangement and added to those having high durability and high performance with respect to the outdoor environment.

INDUSTRIAL APPLICABILITY The present invention can be widely applied to a roof tile as a fixing member for an installation base for installation on a roof, such as an outdoor unit for air conditioning or a solar power generator.
