Description

  The present invention relates to a roof surface ventilation material having a wiring processing function, more specifically, a ventilation material installed on the roof surface in order to perform frame ventilation of a roof surface of a tiled house, and has a function as a ventilation material. In addition, the present invention relates to a roof surface ventilation material having a wiring processing function that holds a cable of a solar cell module installed on the roof surface well.

  In recent years, many buildings to be constructed have a structure having a ventilation layer between the outer wall and the inner wall and a perforated plate under the eaves in order to let out moist air from the room to the outside. The air that has flowed into the ventilation layer and the perforated plate under the eaves flows out to the outside through the back of the shed. For this purpose, ventilators with various shapes have been provided on the back of the hut, or a ventilator is provided. Has been.

Further, in recent years, solar power generation has become widespread from the viewpoint of CO ₂ reduction, and examples of small-scale power generation adopted in ordinary households are rapidly increasing. In the case of a general household, the solar cell module is installed on the roof surface. That is, the solar cell module installed on the roof of the house receives sunlight to generate power, and is transmitted to the power conditioner installed on the wall of the house via a cable extending from the solar cell module and installed indoors. Power is transmitted to the indoor distribution board.

  In general, the cable extending from the solar cell module is drawn into the room by turning the roof surface in a state covered with the cable cover, and wrapping the keraba around. However, in that case, the cable cover is attached to the roof surface. Not only does it look bad because it is exposed, but the cable cover is subject to deterioration and damage due to exposure to wind and rain and direct sunlight, which not only deteriorates the appearance but also requires time for repair and replacement. There is.

  In view of such a problem, a proposal has been made to draw a cable into the back of a hut through an opening provided on the roof surface without causing the cable to run over the roof surface (Japanese Patent Laid-Open No. 2003-312010). However, in the case of the present invention, there is a problem that water may enter the indoor from the opening through which the cable is drawn, and therefore a cable drawing structure that takes into account the waterproof surface of the portion has been proposed (Japanese Patent Laid-Open No. 2005-2005). 281980).

  However, in the case of the cable lead-in structure, it is necessary to provide an opening for drawing the cable on the roof surface, and to install a waterproof member there. However, since the waterproof member is composed of many parts, installation takes time. Of course, the installation work is performed separately from the construction of the ventilation device.

JP 2003-31010 A JP 2005-281980 A

  As described above, in the case of a configuration that has been proposed in the past, the cable extending from the solar cell module is drawn into the back of the hut through the opening provided on the roof surface without causing the roof surface to fold, the waterproofing measures are not sufficient, Since the waterproof member is composed of many parts, it takes time to install, and it is performed separately from the construction of the ventilator, resulting in an increase in work cost.

  Therefore, the present invention does not have such a problem, that is, in the configuration in which the cable extending from the solar cell module is drawn into the back of the hut through the opening provided on the roof surface without passing over the roof surface, It is possible to use the roof surface ventilation material that can hold the cable that has been retracted and can be held well, has no problem with the waterproof surface in the retracted portion, and has a wiring processing function that is easy to construct. The issue is to provide.

  The invention described in claim 1 for solving the above problem comprises a ventilation member formed by connecting a number of ventilation paths extending vertically and horizontally from one side surface to the opposite side surface, and a cover material covering the ventilation member. In the state of being held by the cover material, a gap portion through which a cable extending from a solar cell module installed on the roof surface can be inserted is secured at an end portion or an intermediate portion of the ventilation member. It is a roof surface ventilation material having a wiring processing function.

  In one embodiment, a cable support is fitted into the gap, and the cable is supported by the cable support. The cable support member is made of a resin having elasticity, and carries the cable on the upper surface thereof, or a cut is made from the upper surface to the middle, and the cable is dropped and carried on the cut. The cable support member can be fixed to one end surface of the ventilation member in advance.

  In one embodiment, a drainer is disposed on the lower surface of the ventilation member. In that case, the cable support member may be fixed to the drainer.

  The roof surface ventilation material according to the present invention is as described above, and has a simple configuration that also serves as a ventilation material for the roof surface. The roof surface ventilation material can fit on the roof surface by passing a cable extending from the solar cell module through the gap. Since there is no problem with the waterproof surface in the lead-in portion, and the field board opening for the ventilation material can be used for the cable interior pull-in, the field board opening for the cable can be used. There is no need to provide it separately, and the construction is easy.

  In addition, since the cable extending from the solar cell module drawn into the back of the hut through the tile roof can be held well on the roof surface without being exposed to the outside, the cable may be exposed and the appearance of the house may be impaired. There is no effect.

It is a perspective view which shows the structure of the roof surface ventilation material which has a wiring processing function which concerns on this invention. It is a disassembled perspective view which shows the structure of the roof surface ventilation material which has a wiring processing function which concerns on this invention. It is a longitudinal cross-sectional view which shows the construction state of the roof surface ventilation material which has a wiring processing function which concerns on this invention.

  A mode for carrying out the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 and 2, a roof surface ventilation material having a wiring processing function according to the present invention includes a ventilation member 1 formed by connecting a number of ventilation paths 1 a extending from one side surface to the opposite side surface in a vertical and horizontal direction. And a cover member 2 that covers the ventilation member 1, and a gap portion 9 through which the cable 11 of the solar cell module can be inserted is provided at an end portion or an intermediate portion of the ventilation member 1 while being held by the cover member 2. It is characterized by being.

  The cover member 2 is usually formed by bending a metal plate, and is fixed to the top plate 3 that contacts the upper surface of the ventilation member 1 and the base plate 21 and fixed thereto by screws, nails or the like. The plate 4, a long inclined plate 5 that connects the top plate 3 and the fixed plate 4, and a short inclined plate 6 that extends from the top plate 3 to the opposite side of the long inclined plate 5. In addition, an end plate 7 that closes the end face is connected to both end portions, and a fixing plate 8 that extends into contact with the base plate 21 and is fixed thereto with screws or nails is extended to the end plate 7. The

  The ventilation member 1 is disposed on the back surface of the top plate 3 such that the ventilation path 1a faces the long inclined plate 5 from the short inclined plate 6. A gap 9 is secured through which the cable 11 extending from the solar cell module installed on the roof can be inserted. In other words, one end surface of the ventilation member 1 is separated from the end plate 7, and the space is defined as a gap portion 9 through which the cable 11 can be inserted. As described above, the gap 9 is often provided at one end, but may be provided in the middle of the ventilation member 1.

  Although the ventilation member 1 is good also as fixing to the back surface of the top plate 3 via a double-sided tape or an adhesive agent, it is usually made into the separated state. Further, a drainer 15 having one end rising obliquely is disposed on the lower surface of the ventilation member 1. The drainer 15 may be fixed to the lower surface of the ventilation member 1 in advance via a double-sided tape or an adhesive.

  In one embodiment, the cable support 12 is fitted into the gap 9 and the cable 11 is supported by the cable support 12 (see FIG. 2). Usually, the cable support 12 is made of an elastic resin and is formed in a rectangular parallelepiped shape corresponding to the size of the gap 9. The cable support 11 can be fixed to the end face of the ventilation member 1 or the drainer 15 in advance.

  The cable 11 is placed on and supported by the upper surface of the cable support 12. Alternatively, a cut 14 may be formed from the upper surface to the middle of the cable support member 12, in which case the cable 11 is carried by dropping into the cut 14. The cable support member 12 is fitted into the portion corresponding to the gap 9 in a state where the cable 11 is supported on the upper surface or in the cut 14. Thus, the cable 11 is carried by the cable support member 12 and is held in a stable state in the gap 9.

  Next, the construction method of the roof surface ventilation material of the said structure is demonstrated. This roof surface ventilation material is installed on the tile floor, and prior to the installation, a field plate opening extending in the length direction of the tile frame 22 between the tile frames 22 on the field plate 21 of the ridge. 23 is drilled. Next, the cable 11 extending from the solar cell module is drawn under the roof tile through a through hole 24 provided in the roof tile. The through hole 24 is watertightly sealed with a sealing material as appropriate after the cable 11 is inserted.

  In addition, although the through-hole 24 is drilled in a roof tile at the time of construction, it is good also as using the wiring roof tile provided with the wiring opening and the drawing-in cover 25 in the said construction location (refer FIG. 3). In that case, the labor of drilling the through holes 24 can be saved. The cable 11 drawn under the roof tile is carried by the cable support member 12 and is disposed in a portion corresponding to the gap 9.

  When constructing the roof surface ventilation material according to the present invention, first, the drainer 15 is fixed along the downstream side edge of the field board opening 23 via a double-sided tape or an adhesive. When the ventilation member 1 and the drainer 15 are integrated, the arrangement of the ventilation member 1 is completed as the drainer 15 is fixed. When both are separate bodies, the ventilation member 1 is fixed to a fixed position on the drainer 15 via a double-sided tape or an adhesive. Then, the cable 11 drawn from the through hole 24 is disposed on the upper surface or the cut 14 of the cable support member 12, and the end of the cable 11 is suspended in the field board opening 23.

  Finally, the cover material 2 is placed on the ventilation member 1 so that the fixing plate 4 faces the ridge, and the long inclined plate 5 is placed on the field plate opening 23, and the fixing plate 4 and the fixing plate 8 are covered with the field plate. It fixes to the main plate 21 and the construction of the main roof surface ventilation material is completed. In this state, the cable 11 is held in a firm state as the cable support 12 having elasticity is compressed by the top plate 3. The position of the through hole 24 is arbitrary and is not necessarily the position shown in FIG.

  Since the roof surface ventilation material according to the present invention is installed in this manner, the cable 11 extending from the solar cell module is drawn through the tile without exposing anything, and is held in the roof surface ventilation material so as to fit well. It is drawn into the back. Therefore, a situation in which the appearance of the house is not damaged by the cable 11 being exposed on the roof surface does not occur.

  The function of the roof surface ventilation material according to the present invention as a ventilation material is not particularly different from the conventional one. That is, the air rising from the back of the hut passes through the field plate opening 23, passes into the space surrounded by the long inclined plate 5 and the ventilation member 1, and then passes through the ventilation path 1 a of the ventilation member 1. It is discharged into the space under the roof tile.

  Further, since the through hole 24 through which the cable 11 is inserted is properly watertightly sealed with a sealing material after the cable 11 is inserted, it is possible to prevent water from entering from there. However, with deterioration of the sealing material, etc. It can also be flooded. However, even if it is flooded from there, the infiltrated water falls on the main roof surface ventilation material or falls on the field plate 21, so that it does not flow to the ventilation member 1 side in a normal climatic state. The base plate opening 23 does not pass through the one air passage 1a. Even if there is a case of passing through the air passage 1a, the drainer 15 reliably prevents further progress.

  Although the invention has been described in some detail with its most preferred embodiments, it is evident that a wide variety of embodiments can be constructed without departing from the spirit and scope of the invention. Accordingly, the invention is not limited to the specific embodiments except as limited in the appended claims.
