Description

  The present invention relates to an attachment member.

In recent years, systems such as solar cell panels and solar water heaters that are mounted on the roof of a building to generate power using sunlight, and systems that heat water using solar heat have become widespread.
As a method of attaching such equipment to the roof, a method of attaching the equipment to the gantry by forming an attachment hole in the base plate or tile material constituting the roof, attaching the attachment member there, and attaching the equipment to the gantry (so-called roof-standing type) )It has been known. In this case, the mounting holes formed in the base plate are waterproofed with a caulking agent or butyl tape so that rainwater or the like does not enter.
However, caulking is difficult to keep waterproof for a long time due to deterioration of the caulking agent. Moreover, in the case of the above-mentioned attachment method, it has been pointed out that there is a risk of water leakage due to construction failure depending on the skill of the installer such as the attachment angle of the fixing screw to the attachment hole.

In the following Patent Document 1, a plate-shaped base, a support having one end fixed to the surface side of the base, and a rail or roof installation body attached to the other end of the support are described. A roof fixing device with an upper support for fixing is described.
Also, here, a hole is provided in the roof tile, and a movable part that covers the hole is installed on the hole, and a hole is provided in the movable part so that the column can be inserted and moved up and down. It is described that the size of the hole is larger than the size of the support column.
According to this, since a support | pillar can move freely to an up-down direction along the hole of a movable part, it is supposed that stress is not applied to the waterproof processing part of a tile material, and prevention can be maintained.

However, the vertical rack 90 of the illustrated example is made of a steel material having an I-shaped cross section and protrudes in a bowl shape. The support member 3 is connected to the lower end portion 90 a by the connector 14, and the vertical rack 90 is supported on the roof 5.
The horizontal rack 91 is made of a steel material having an inverted U-shaped cross section, and is connected and fixed to the vertical rack 90 by a connector 92 (see FIG. 1).

The solar cell panel shown in the figure as an example of the device 10 is formed of a thin plate body, and its four circumferences are surrounded by a frame member 10a made of aluminum or the like. A large number of solar cells are provided inside the frame member 10a, and the energy of sunlight is converted into electric power to generate electric power. A hook-shaped locking portion 10aa is formed at the end of the frame member 10a, and the locking portion 10aa is locked and attached to the horizontal rack 91.
In addition, the electric power obtained from the solar cell panel is converted from direct current to alternating current for use in a dedicated unit (not shown) for home use or the like.

The attachment member 1 for attaching and fixing the device 10 to the roof 5 will be described in more detail.
The attachment member 1 includes the fixing member 2, the support member 3, and the packing material 4 as described above.
The fixing member 2 is configured by a plate-like fixing portion 20, and a through hole 21 for holding the supporting portion 30 in a state of passing through the support portion 30 is formed at a substantially central portion of the fixing portion 20. The fixing portion 20 is also formed with a plurality of insertion holes 20a through which the fixture 11 driven into the base plate 7 is inserted.
The lower surface of the fixing portion 20 may be waterproofed with butyl tape or the like. In the figure, reference numeral 14 denotes a waterproof treatment layer.

The support portion 30 is formed of a solid cylinder, and a plate-like pedestal portion (not shown) is provided on the side where the fixing portion 20 is disposed, and is fixed with the fixing portion 20 covering the pedestal portion. By doing so, the support portion 30 can be erected on the roof 5 as shown in the figure.
Since the front side of the support portion 30 has a function of a bolt shaft, a thread groove is formed, and the nut 14a and the washer 14b are attached so as to be firmly connected to the lower end portion 90a of the vertical rack 90. It is configured.
A through-hole 81 is formed in the roof tile 8 so that the support portion 30 is disposed therethrough. It is desirable that the size of the through hole 81 is larger than the diameter of the support portion 30 so that a slight positional shift can be absorbed.
The packing material 4 is attached to the through hole 81 so as to close the gap in a state where the support portion 30 is penetrated.

The packing material 4 is made of a rubber material or the like, and is attached in a state where the packing material 4 penetrates the support portion 30 and is in close contact with the tile material 8. The packing material 4 is attached in close contact with the outer periphery of the support portion 30 so as to completely cover the shaft periphery portion 40 formed so as to be wound along the axial direction of the support portion 30 and the through hole 81 of the tile material 8. And a cover portion 41 having a diameter larger than the outer diameter of the through-hole 81. The cover portion 41 is formed so that the diameter gradually increases as it approaches the tile material 8 side, and has an inclined shape with an expanded hem when viewed in cross section as shown in FIG.
In the figure, reference numeral 13 denotes a caulking layer, in which a caulking agent is filled in the gap between the through hole 81 of the roof tile 8 where the packing material 4 cannot be attached and the support portion 30 to improve waterproofness.

A cushion material 12 is disposed between the field board 7 and the tile material 8 in a compressed state. The cushion material 12 is made of a synthetic rubber foam or the like. For example, a semi-closed cell foam mainly composed of EPDM synthetic rubber is preferably used as the cushion material 12. The material of the cushion material 12 is not limited to this, and any material may be used as long as it can easily follow an uneven surface, can be easily compressed, and can exhibit a stable sealing property over a long period of time.
The illustrated example shows an example using a cushion material 12 made of a semi-closed cell foam mainly composed of EPDM synthetic rubber. As shown in FIG. 2 (c), the cushion material 12 may be formed in a donut shape by being pierced through a substantially cylindrical center to form a through hole 12a and being divided into a plurality of pieces. It is desirable that the through hole 12 a has substantially the same diameter as the diameter of the support portion 30.
According to this, it can attach to the support part 30 without a clearance gap, can prevent the penetration | invasion of the water to the fixing | fixed part 2, and can improve waterproofness.

As described above, if the cushion material 12 is divided into a plurality of pieces, the number of the cushion materials 12 is changed even when the gap size between the base plate 7 and the tile material 8 differs depending on the type of the tile material 8. It can respond by doing. The cushion material 12 may be attached by inserting the through hole 20a into the support portion 30 and penetrating it, and can be easily attached without worrying about displacement.
Therefore, in the case of the illustrated example, the separately formed cushion material 12 is matched to the gap dimension between the base plate 7 and the tile material 8 (more specifically, from the upper surface of the fixing portion 20 to the back surface of the tile material 8). However, the present invention is not limited to this example.
For example, in the case of S-shaped roof tiles, the above-described gap is larger than that in the case of the roof tile 8 shown in the figure. Therefore, 4 to 5 tiles may be arranged in accordance with this, and a general Japanese roof tile. In this case, it is possible to adjust by changing the number of the cushion materials 12 to be placed, such as arranging 3 to 4 pieces.

Next, the attachment point of the attachment member 1 to the roof 5 is demonstrated, referring a figure.
First, the mounting position of the device 10 on the roof 5 is determined, and the existing tile material 8 is removed (see FIGS. 2A and 2B). Here, the once-removed roof tile 8 is formed with a through hole 81 through which the support portion 30 penetrates at a predetermined position. A waterproof treatment layer 14 is formed by sticking butyl tape or the like at a desired position on the lower covering material 70. The fixing member 2 is arranged, the fixing tool 11 is inserted into the insertion hole 20a (see FIG. 1) of the fixing portion 20 and screwed into the field plate 7, and the fixing portion 20 is fixed to the roof 5. At this time, the fixing portion 20 is put on the through hole 21 of the fixing portion 20 so that the supporting portion 30 is erected from the fixing member 2 and is fixed to the roof 5 in that state (see FIG. 2 (c)).
Here, the screwing position by the fixing tool 11 is not particularly limited, but can be firmly attached if the fixing tool 11 can be driven into the rafter 6 as shown in the figure. In addition, an adhesive may be applied to the lower surface of the fixing portion 20 in order to improve the adhesion to the roof 5.
When the support member 3 is fixed so as to protrude from the roof 5, the cushion material 12 is attached to the support portion 30 (see FIG. 2D).
And the support part 30 is penetrated to the through-hole 81 formed in the removed tile material 8, and the tile material 8 is attached to the original position. When returning the tile material 8 to the original position, the cushion material 12 of the tile material 8 is compressed by about 50% by the weight of the tile material 8 (see FIGS. 3A and 3B).
Then, the caulking agent is filled in the gap between the outer periphery of the support portion 30 and the inside of the through hole 81 in a state where the support portion 30 is passed through the through hole 81 of the roof tile 8, and the coking layer 13 is formed thereon. A packing material 4 is attached.
Then, the nut 14 a and the washer 14 b are attached from the front end side of the support portion 30, and the washer 14 b and the nut 14 a are further attached in a state where the vertical rack 90 is interposed, and is firmly screwed to the support portion 30. In this way, by tightening and fixing the support portion 30 which is also a bolt shaft with the double nuts 14 a and 14 a, the weight of the vertical rack 90 is added and the cushion material 12 is further compressed between the base plate 7 and the roof tile 8. Become.

According to the above, the attachment member 1 with the cushioning material 12 interposed can be attached firmly to the roof 5 easily.
Further, the through-hole 81 of the tile material 8 is covered with the packing material 4 and closed with the caulking layer 13, and the elastic cushion material 12 is compressed between the field board 7 and the tile material 8. It is arranged by. Therefore, for example, even if rainwater flows along the roof 5 from the upstream side, the intrusion of rainwater can be prevented. Moreover, even if the mounting angle of the fixing device 11 is bad, the risk of water leakage having such a waterproof structure can be reduced, and the waterproof layer 14 is not exposed to rainwater and the like for a long time. A waterproof function can be demonstrated.

  In addition, the shape of the attachment member 1 and each member which comprises this, a structure, a connection structure, etc., and the shape of each member which comprises the roof 5, a structure, a connection structure, etc. are not limited to an example of a figure. The device 10 is not limited to the illustrated solar cell panel.
