[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar heat collecting roof of a passive solar house utilizing solar energy by air.

[0002]

2. Description of the Related Art In a passive solar house that effectively uses air collected by sunlight, a solar heat collecting section is formed on a roof or a wall, and warm air is obtained therefrom and taken into a room. The solar heat collector provided in
For example, as shown in FIG. 5, a lower surface of an air flow path 2 having a roof gradient formed immediately below a metal roof plate 1 such as a color iron plate is formed as a heat insulating layer 3 laid with glass wool or the like, and an air flow path is formed. One end of 2 is opened under the eaves and the like, and a part of the roof is covered with glass 4.

[0003] The solar heat collecting roof serving as the solar heat collecting portion is a floating roof of a tiled-roof type and has rafters 5a and 5 having different diameters.
b is made up and down double with a large diameter rafter 5a at the bottom, and a step is formed. A roof plate 1 made of a color iron plate is laid on the roof, and an air layer 2a is secured on the lower side to form an air flow path 2.

The airtightness of the air layer 2a is determined by the rafters 5a, 5
A sealing material 6 such as silicone caulking is applied to the outer surface of the roof b with a caulking gun or the like, and then the edge of the shingle 1 is secured by overlapping.

[0005]

However, since the solar heat collecting section shown in FIG. 5 requires a seal with a caulking gun or the like, the workability of construction is poor and it takes time and effort.
It was often difficult to ensure high airtightness.

An object of the present invention is to eliminate the disadvantages of the above-mentioned prior art, and it is possible to ensure high airtightness without the application of caulking, to simplify the construction, and to enhance durability and economy.

Hang down along the sides, and lay the roof shingle across the bearing flanges between the rafter hardware to form an air layer underneath, and edge the roof shingle from the outside with the lower folded piece. When fitting the cap material to the rafter hardware to cover it, a sealing material is sandwiched between the two, and the sealing material is provided in the groove of the rafter hardware and provided on the inner surface of the cover plate These packings and airtight tapes It is an Abstract that is brought into contact with.

In addition, as a solar heat collecting wall having a vertical air flow path on a wall, a fixing flange is provided at one lateral end of a hollow body having a rectangular cross section, and a supporting flange is provided at a lateral intermediate portion in a lateral direction. A pier metal having a groove for packing arrangement formed on the front left and right sides is formed of an extruded aluminum alloy material, and a protrusion for engagement is formed on an inner surface of a cover plate formed with an inner folded piece on the left and right. The cap material protruding in parallel with an interval is formed of an extruded shape of aluminum alloy, the pier hardware is installed at appropriate intervals, along the side from the front of the pier hardware, and between the pier hardware. When the wall plate is extended so as to extend between the bearing flanges to form an air layer inside, and when the cap material is fitted to the pier hardware so as to cover the end of the wall plate from the outside with the inner folded piece, Sandwiching a sealing material between them, and the sealing material, A packing disposed in the groove of the wooden hardware consists airtight tape disposed on the inner surface of the cover plate, it is an Abstract that is brought into contact with these packing airtight tape.

According to the first aspect of the present invention, since it is composed of two pieces of the rafter hardware and the cap material, double construction of the rafter unlike the conventional construction is eliminated, and the construction period can be shortened. In addition, since the airtightness can be obtained by sandwiching the sealing material between the rafter hardware and the cap material, it is simpler and more reliable than in the related art in which the entire roof is obtained. Also,
No caulking cracks due to no caulking.

In addition, since the rafter hardware and the cap material use extruded aluminum alloy, they are lightweight, easy to work, durable, weather resistant, resistant to corrosion, and reduced in maintenance costs.

According to the second aspect of the present invention, in addition to the above functions, the sealing material comprises a packing and an airtight tape, and the packing can be disposed in advance in the groove of the rafter hardware, and the airtight tape is previously covered. By arranging it on the inner surface of the board, it is possible to easily attach the cap material when fitting the cap material to the rafter hardware, and the arrangement work is also simple.

According to the third aspect of the present invention, the same applies to the case where a vertical air flow path is provided on a wall as a solar heat collecting wall. The airtightness can be shortened, and the airtightness can be obtained by sandwiching the sealing material between the hardware of the pier and the cap material, so that it is simple and reliable. In addition, there is no coking cracking due to no caulking.

Further, since the extruded shape of the aluminum alloy is used for both the crosspiece hardware and the cap material, it is lightweight, easy to work, durable, weather-resistant, hardly corroded, and reduced in maintenance cost.

According to the fourth aspect of the present invention, as in the second aspect of the present invention, the sealing material is made of a packing and an airtight tape, and the packing can be disposed in advance in the groove of the pier hardware. By arranging the airtight tape on the inner surface of the cover plate in advance, it can be easily attached when the cap member is fitted to the pier hardware, and the arranging operation is also simple.
