Description

[0001]
BACKGROUND OF THE INVENTION
The invention of this application relates to a fixing structure for a roof installation member. More specifically, the structure of this application relates to a structure in which a functional roof installation member such as a solar cell module or its panel is screw-fixed on an existing roof.
[0002]
[Prior art]
Solar cell panels, solar hot water supply systems, and the like are becoming popular in ordinary houses, and it is also frequently performed to retrofit and fix these facilities (roof installation members) on the existing roof surface.
[0003]
The method illustrated in FIG. 4 is known for fixing the roof installation member on an existing roof surface such as a house. In the conventional method illustrated in FIG. 4, in the laminated structure including the roof plate (2) such as the base plate (2), the base sheet (3), and the slate tile as the roof (1), Place the frame material (5) in the fixed location (Fig. 4A), and make a screw hole (6) in this frame material (5) and the roof material (4) (Fig. 4B), and silicon in this screw hole (6) After injecting caulking material (7), etc. (Fig. 4C), screw (8) is rotationally inserted to attach fitting (9), and roof installation member (10) is fixed to this fitting (9). (FIG. 4D). Thus, maintaining the waterproofness of the roofing material (4) by filling the screw hole (6) with the caulking material (7) is attempted.
[0004]
[Problems to be solved by the invention]
However, in the case of a fixing structure according to the conventional method as illustrated in FIG. 4, it is not easy to inject a caulking material (7) such as silicon having high viscosity into the screw hole (6). Although a cushioning material is placed around 6) and the caulking material (7) is pushed into the screw hole (6) in several ways using its elasticity, it is actually used. Insufficient response.
[0005]
The caulking material (7) serves to seal the screw hole (6) but does not reach the base sheet (3) as shown in FIG. 4D. For this reason, rainwater or the like may infiltrate the base plate (2) from the tear of the base sheet (3) caused by the penetration of the screw (8), which may cause deterioration of the roof structure.
[0006]
The invention of this application has been made in view of the circumstances as described above, and can easily perform the mounting process of the roof installation member, and can reliably waterproof the periphery of the screw fixing portion. It is an object to provide a new fixing structure for an installation member.
[0007]
[Means for Solving the Problems]
In this application, the upper region of the screw main body is covered with a sealing material, and the screw having a caulking material filled in the recess at the lower end of the sealing material penetrates the roof material. Te is puncture the underlying sheet and sheathing plate, sealing material and caulking material of this screw is sealed screw holes roofing and sealing material lower end to provide a structure which is characterized in that in close contact with the base sheet .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail and specifically with reference to the accompanying drawings.
[0010]
FIG. 1 is a side sectional view illustrating a fixing structure of the invention of this application . In the fixed structure illustrated in FIG. 1, the existing roof (1) is a laminated structure composed of a base plate (2), a base sheet (3), and a roof material (4) such as a slate tile, and a roof installation member The frame material (5) is placed in the fixed part of And the connection fitting (9) is connected to the base sheet (3) and the base plate (2) through the screw (11) through the screw holes (6) of the frame material (5) and the roof material (4). The roof mounting member (10) is fixed to the connection fitting (9). Note that the roof installation member (10) covers all device systems installed on the roof surface, such as solar cell panels, solar water heating systems, wind power generation systems, and radio wave antennas.
[0011]
FIG. 2 is a side view of a screw used in the fixing structure of the invention of this application. The screw ( 11 ) shown in FIG. 2 has a sealing material ( 13 ) coated on the upper region of the screw main body ( 12 ), and a recess ( 16 ) is formed at the lower end of the sealing material ( 13 ). Yes. And this screw ( 11 ) is rotationally inserted into the base sheet (3) and the base plate ( 2 ) through the screw hole ( 6 ) in a state in which the concave portion ( 16 ) is filled with the caulking material (7). . At this time, crushed tip of the recess (16), as presented in Figure 3, caulk (7) is pressed into the screw holes (6), the inner wall surface Bisushiru material screw holes (6) (13 ), A layer of caulking material ( 7 ) is formed, and the sealing performance of the screw hole ( 6 ) is further improved. At this time, the lower end surface ( 14 ) of the sealing material ( 13 ) is in close contact with the base sheet (3) and completely seals the insertion portion of the screw main body ( 12 ). As the caulking material (7), the same silicon as the conventional example can be appropriately selected and used. Further, the size of the recess ( 16 ) and the amount of the caulking material ( 7 ) filled therein can be appropriately adjusted according to the diameter of the screw hole ( 6 ), the thickness of the sealing material (13) , and the like.
[0012]
The sealing material (13) may be any material as long as it has elasticity, durability, and waterproofness, and examples thereof include silicon, rubber, and synthetic polymer gel. The thickness of the seal material (13) portion of the screw body (12) is substantially the same as the diameter of the screw hole (6). For example, when the diameter of the screw hole (6) is 10 to 16 mm, the thickness of the seal material (13) can be about 9 to 17 mm. Further, the range (length) of the sealing material (13) covering the screw body (12) is the same as the distance from the upper surface of the frame material (5) to the base sheet (3) or longer by about 1 to 2 mm. Range. For example, when the distance from the upper surface of the frame material (5) to the base sheet (3) is 50 mm, the range from 50 to 52 is covered with the sealing material (13) from the upper end of the screw body (12). do it.
[0013]
In the example of FIG. 2 , the surface of the screw main body (12) is shown in a plane, but it goes without saying that a spiral screw groove is actually formed. Moreover, although the screw (11) in a state where the washer (15) is combined is illustrated in FIG. 2 , the washer (15) may be integrated with the screw (11) or may be a separate body.
[0015]
The invention of this application is not limited by the above examples, and it goes without saying that various details are possible.
[0016]
【The invention's effect】
As described above in detail, according to the invention of this application, there is a new fixing structure of the roof installation member that can easily perform the mounting process of the roof installation member and can reliably waterproof around the screw fixing portion. Provided.
