Description

  The present invention relates to a functional member mounting structure in which a base plate is disposed on a roof material and a functional member is fixed to the surface of the base plate.

  Conventionally, a functional member mounting structure in which a functional member such as a photovoltaic power generation panel is disposed on a roof via a base plate has been often used (see, for example, Patent Document 1).

  Such a functional member mounting structure generally fixes a functional member (not shown) to the fixing bar 5 of the base plate 2 fixed to the surface of the roof material 1, as shown in FIG.

  The base plate 2 is formed in a wave shape in which peaks and valleys are continuous in the left-right direction (the direction perpendicular to the paper surface in FIG. 5), and the fixing bar 5 to which the peripheral edge of the functional member is fixed extends in the left-right direction of the base plate 2. It is attached so as to straddle a plurality of mountain parts along. Further, a fixing tool insertion hole 20 through which a fixing tool 4 ′ for fixing the base plate 2 to the roof material 1 is inserted is formed in the mountain portion. In addition, the code | symbol 11 in a figure shows the waterproof sheet affixed on the surface of the roofing material 1, and the code | symbol 6 shows the attachment bar (it mentions later) attached to the part in which the fixing tool penetration hole 20 of the mountain part was formed. In the example shown in FIG. 5, the mounting bar 6 is composed of a bottom plate 61 and reinforcing portions 62 formed on both sides in the short direction, and is mounted so as to straddle a plurality of mountain portions along the left-right direction of the base plate 2. In addition, a through hole (not shown) is formed in a portion corresponding to the fixing tool insertion hole 20 in the peak portion of the bottom plate 61.

  In this conventional functional member mounting structure, when mounting the base plate 2 to the roofing material 1, the base plate 2 is placed on the roofing material 1, and the through hole of the mounting bar 6 and the fixing tool insertion hole of the base plate 2 are mounted. The caulking material 7 is injected between the base plate 2 and the roof material 1 through 20 (see FIG. 5A), and the through hole of the mounting bar 6 and the fixing tool insertion hole 20 of the base plate 2 are viewed from above. The fixing tool 4 ′ is inserted and fixed to the roof material 1 by screwing, and the screwed portion of the fixing tool 4 ′ to the roof material 1 is waterproofed by the caulking material 7.

In such a functional member mounting structure, since the caulking material 7 is injected between the base plate 2 and the roof material 1 as described above, the injection work is necessary and the workability is poor. In addition, the amount of injection of the caulking material 7 differs depending on the installer, and a stable waterproofing effect cannot be obtained. In addition, there is a possibility that the injection of the caulking material 7 is forgotten and the waterproofing may not be performed. .
JP 2003-31010 A

  The present invention has been made in view of the above points. The purpose of the present invention is to install a functional member on a roofing material, and the workability of the caulking material is deteriorated and the waterproof effect is stable. It is an object of the present invention to provide a functional member mounting structure in which there is no possibility that the product will not be obtained or waterproofing may not be performed.

  In order to solve the above problem, in the invention according to claim 1, in the functional member mounting structure in which the base plate 2 is disposed on the roofing material 1 and the functional member 3 is fixed to the surface of the base plate 2, A fixing tool insertion hole 20 through which the fixing tool 4 for fixing to the roofing material 1 is inserted is formed in the plate 2, and the fixing tool 4 is elastic from the back surface of the head 40 a of the screw 40 to the intermediate portion of the shaft portion 40 b. A cylindrical packing material 41 is fitted and formed, and the fixing tool 4 is inserted into the fixing tool insertion hole 20 of the base plate 2 disposed in the roofing material 1 and screwed into the roofing material 1 to be fixed. 41 is compressed between the roofing material 1 and the base board 2, It is characterized by the above-mentioned. With this configuration, the packing material 41 of the fixing tool 4 can be waterproofed by being pressed against the portion of the roofing material 1 to which the fixing tool 4 is attached, and the base plate 2 is attached to the roofing material 1. This eliminates the need to use caulking material, improves the workability by eliminating the need to inject the caulking material, and does not provide a stable waterproof effect due to the difference in the amount of caulking material injected by the installer. There is no such thing as being forgotten and not waterproofed.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, a flange portion 42 is formed on the packing material 4 along the back surface of the head 40a of the screw 40. With such a configuration, when the fixing tool 4 is inserted into the fixing tool insertion hole 20 of the base plate 2 from above and is screwed and fixed to the roofing material 1, the back surface of the head 40a of the fixing tool 4 and the upper surface of the base plate 2 are secured. The flange portion 42 of the packing material 4 can be sandwiched between the fixing member insertion hole 20 of the base plate 2 and water can be stopped.

  In the present invention, the packing material of the fixing tool can be waterproofed by being pressed against the portion to which the fixing tool on the roofing material is attached, and it is not necessary to use a caulking material to attach the base plate to the roofing material. In addition, the injection work is unnecessary and the workability is improved, the amount of injection of the caulking material by the installer is different, and a stable waterproofing effect cannot be obtained, or the water is not waterproofed by forgetting the injection of the caulking material There is no.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  In the functional member mounting structure in the present invention, as shown in FIG. 3, a base plate 2 is disposed on a roof material 1 and a functional member 3 such as a photovoltaic power generation panel is fixed to the surface of the base plate 2. . The roofing material 1 is not particularly limited, such as a base material such as a field board, or a surface material of a base material such as a field board provided with a roof surface material (for example, tiles). The base plate 2 is placed side by side in the eaves ridge direction and in the left-right direction perpendicular thereto.

  As shown in FIG. 4, the base plate 2 is formed in a wave shape in which crests 21 and troughs 22 are alternately continued in the left-right direction B, and is usually formed of metal. The top part of the part 21 and the bottom part of the valley part 22 have a flat trapezoidal shape, and the fixing bar 5 and the mounting bar 6 described later are attached so as to straddle the planar top parts of the plurality of peak parts 21. Moreover, when this base board 2 is attached to base materials, such as a field board, as the roofing material 1, this itself may have a function as a roof.

  As shown in FIG. 3, the base plate 2 adjacent to the eaves ridge direction A is stopped by overlapping the upper and lower ends of the base plate 2, and one base plate is adjacent to the base plate 2 adjacent in the left-right direction B. Water is stopped by fitting the peak portion 21 at the side end portion of 2 and the peak portion 21 at the side end portion of the other base plate 2. Further, by forming the base plate 2 in a wave shape, positioning in the left-right direction B is facilitated, drainage to the eaves side A1 is facilitated, and in addition, the thickness of the base plate 2 is increased. In addition, the bending rigidity in the eave building direction A can be increased, the required strength can be obtained while reducing the cost, and the ridge side end of the base plate 2 (the upper end of the base plate 2 in FIG. It is formed in a flat plate over almost the entire length, so even if rain water flows backward from the lower surface of the eave side end, water is blocked at the flat ridge side end, preventing further reverse flow, It has a structure that can prevent rainwater from entering the gap between the base plate 2 and the roof material 1 located on the ridge side.

  As shown in FIG. 3, metal fixing bars 5 are respectively attached to the eaves side end and the ridge side end of the base plate 2, and the periphery of the functional member 3 is supported by the fixing bars 5. It is like that.

  As shown in FIGS. 1 and 3, a mounting bar 6 is attached to the base plate 2 so as to straddle a plurality of peak portions 21, and the base plate is attached to a portion where the mounting bar 6 of the peak portion 21 is attached. A fixing tool insertion hole 20 through which a fixing tool 4 (described later) for fixing 2 to the roofing material 1 is inserted is provided. The mounting bar 6 extends upward from the longitudinal bottom plate portion (see reference numeral 61 in FIG. 5) straddling the plurality of mountain portions 21 along the left-right direction B of the base plate 2 and both ends of the bottom plate portion in the short direction. A pair of projecting reinforcing portions having a rectangular tube shape (see reference numeral 62 in FIG. 5) are integrally formed, and a through hole (see FIG. 5) is formed in a portion corresponding to the fixing tool insertion hole 20 of the base plate in the bottom plate portion. (Not shown) is formed, and the fixing tool 4 is inserted in a state where these through holes and the fixing tool insertion hole 20 communicate with each other.

  In the case where two base plates 2 are laid side by side in the eave building direction A by attaching the mounting bar 6 closer to the eaves side A1 than the intermediate position in the eave building direction A of the base plate 2 Because the ridge side end of the base plate 2 on the eave side A1 can be pressed and fixed from above by the eave side end of the base plate 2 on the ridge side A2, the position close to the eave side A1 of the base plate 2 on the eave side A1 It is possible to increase the fixing force of the entire base plate 2 to the roofing material 1 while reducing the number of the mounting bars 6 simply by attaching the mounting bars 6 to the roof.

  Thus, when the functional member 3 is disposed on the roofing material 1, first, the plurality of base plates 2 are laid on the roofing material 1. At this time, the base plate 2 of the eave side A1 is placed so as to be aligned with the end of the eave side A1 of the roofing material 1, and the base of the ridge side A2 adjacent thereto is placed on the upper surface of the ridge side end of the base plate 2. The eaves side end of the plate 2 is installed so as to overlap from above.

  Thereafter, a mark (particularly a figure) provided on the upper surface of the base plate 2 with the longitudinal direction of the mounting bar 6 facing the left-right direction B of the base plate 2 and the mounting bar 6 straddling the plurality of peaks 21 of the base plate 2. (Not shown), the mounting bar 6 is placed. At this time, the release paper on the back surface (adhesion surface) of the mounting bar 6 is peeled off, and is temporarily bonded to the mark of the base plate 2. Then, the base plate 2 is attached to the roofing material 1 by screwing and fixing the fixing tool 4 to be described later from the upper side of the mounting bar 6 to the roofing material 1 through the through hole of the mounting bar 6 and the fixing tool insertion hole 20 of the base plate 2. At the same time, the functional member 3 is attached to the fixing bar 5 of the base plate 2. As a result, the fixing force of the base plate 2 to the roofing material 1 is strong, can be easily and firmly attached, and the functional member 3 can be constructed with excellent workability and design.

  Here, the fixing tool 4 will be described. As shown in FIG. 2, the fastener 4 is formed by fitting a packing material 41 on a screw 40 including a head portion 40a and a shaft portion 40b from the back surface of the head portion 40a to an intermediate portion of the shaft portion 40b. The packing material 41 has a substantially cylindrical elasticity, and its outer diameter is smaller than the inner diameter of the fixing tool insertion hole 20 of the base plate 2 and the through hole of the mounting bar 6, and the length (natural length). ) Is formed longer than the distance from the top surface of the roof material 1 to the bottom surface of the mountain portion 21 of the base plate 2 when the base plate 2 is attached to the roof material 1. Furthermore, in this embodiment, the collar part 42 in alignment with the back surface of the head 40a of the screw 40 is formed in the upper end part of the packing material 41. As shown in FIG.

  This fixing tool 4 is inserted from above through the through hole of the mounting bar 6 of the base plate 2 placed on the roofing material 1 and the fixing tool insertion hole 20 of the base plate 2 communicating with this, and the shaft portion 40b of the screw 40 is inserted. The front end is screwed into the roofing material 1 and the base plate 2 is fixed to the roofing material 1. When screwed and fixed in this way, the space between the base plate 2 and the roofing material 1 (to be exact, the head of the fixing tool 4 is fixed). The packing material 41 is compressed between the back surface 40a and the upper surface of the roof material 1), and the lower end portion of the packing material 41 is pressed into contact with the peripheral edge portion of the roof material 1 where the fixing tool 4 is screwed. This means that the screwed portion of the roofing material 1 is waterproofed (see FIG. 1). And since the collar part 42 is provided in the packing material 41, it is fastened in the state which clamped the collar part 42 of the packing material 41 between the head 40a back surface of the fixing tool 4, and the base plate 2 upper surface. Thus, the fixing tool insertion hole 20 of the base plate 2 is also waterproofed, and water can be prevented from entering the packing material 41 from the upper end portion of the packing material 41.

  In this embodiment, the mounting bar 6 is provided on the peak portion 21 of the base plate 2, but the fixing tool 4 is directly inserted into the fixing tool insertion hole 20 of the base plate 2 without attaching the mounting bar 6. But you can. Moreover, the functional member 3 is not limited to a photovoltaic power generation panel.
