Description

[Detailed Description of the Invention] This invention relates to the improvement of a roof structure that actively contributes to the utilization of solar heat, and aims to provide a roof structure that is simple in structure and useful for energy saving by effectively utilizing solar thermal energy. be.

Most of the conventional solar heat utilization devices simply consist of pre-framed solar heat collection devices arranged on a general roof with only rain protection in mind.

Another proposal was to omit the roof plates when arranging solar heat collectors, but in such a type, the heat collectors themselves, which are pre-framed, need to be used as a roofing material. Since sufficient consideration has not been given to rain protection performance, numerous problems remain that need to be resolved in construction.

Here, this invention proposes a roof structure using a roofing material that is itself part of a solar heat collection device using relatively long extruded shapes, and is a feature of this invention. However, (1) the roof material, which also serves as a light-concentrating plate, is constructed from extruded shapes.

(2) This roofing material must have heat-exchanging heat radiating fins integrally formed on its lower surface.

(3) Transparent panels were supported at regular intervals on the top surface of this roofing material.

(4) On both sides of this roofing material, mounting pieces are integrally formed, which have a bottom part for overlapping adjacent roof panels and fixing them to the rafters.

(5) For this installation, a rising part is formed on the piece, and a shoulder part is integrally knitted at the upper end of the rising part.

(6) The hook portion of the cover that closes the space between adjacent roofing materials is locked to the shoulder portion of the rising portion, and the cover holds down the side plate of the transparent plate to fix the transparent plate.

(7) Heating the L°C air between the rafters by utilizing the space formed between the heat insulating materials placed on the roof structural material.

The configuration having these features provides the following effects.

That is, (a) the roof material is formed of a shape material that also serves as a light collecting plate, and the heat dissipation fins are integrally molded thereon, so that the heat transfer efficiency is high.

(b) Installation is easy because the peripheral pieces are integrally formed on the side edges of the roofing material.

(e) Since the light-transmitting plate is placed on the roofing material and fixed at a temperature of 0.degree. C. by a cover that closes the space between the roofing materials, the number of construction steps is extremely simplified.

Next, the present invention will be described in detail with reference to the accompanying drawings.

In FIGS. 1 and 2, 1 is a main building as a component of a house, and this main building 1 is supported by pillars 3 via beams 2 (see FIG. 2).

Roofing materials 5 are successively placed between the rafters 4 installed in a direction substantially perpendicular to the main building 1, and this roofing material 5 is made of a relatively long extruded aluminum alloy section, with one end attached to the roofing material 5. As for the mounting part, a substantially L-shaped mounting is formed with a circumferential piece 6, and a substantially L-shaped mounting is formed on the other end so that it just fits into the circumferential piece 6. The piece 1 is formed as a mounting section.

In addition, for these installations, there are bottom portions 6a, 7a and vertically rising portions 6b, 7 on both sides of the peripheral piece 6°7, respectively.
b is formed.

On the upper surface of the roof material 5, that is, on the upper surface of both ends of the outdoor side surface, banking seats 8, 9 are protrudingly provided in the vicinity of the circumferential pieces 6, 7. Banking 10 and 11 are fitted to form a temporary placement part that is both translucent and shielded.

In addition, projecting edges 12 are provided at appropriate intervals on the roofing material 5 to support translucent and transparent sheets, which will be described later. Provide a surface (high absorption of heat source, low radiation).

Incidentally, heat dissipation fins 14 are provided protrudingly at appropriate intervals on the lower surface of the roofing material 5, that is, the surface on the indoor side, and the mounting of the above-mentioned both ends is carried out by attaching the rising portions 6b and 7b of the circumferential pieces 6 and 7. Shoulders 15 and 16 extend laterally from the top toward the center of the roof material 5, and rainwater returns L17 and 1g are formed that are connected to these shoulders 15 and 16 and extend obliquely upward.

When attaching the roofing material 5 to the rafters 4, between the adjacent roofing materials 5 and 50, one end side is attached to the bottom side 6a of the peripheral piece 6, and the other end side is attached to the bottom side 7a of the piece 7. After overlapping them, both the circumferential pieces 6 and 7 are fixed to the rafter 4 using bolts 19.

Next, a light transmitting and blocking plate 20 is placed between the bankings 10 and 11, and a cover 21, which is a bar-like member formed in a gate shape, is fixed by covering the circumferential piece 6. At this time, the hanging edges 22 at both ends of the cover 21.
Banking 26.27 fitted into banking seat 24.25 formed at the lower end of 23 and said banking 10.1.
1, and this state is maintained as follows.

That is, the knock portions 28 and 29 extending diagonally upward from the hanging edges 22 and 23 are hooked onto the shoulders 15 and 16 from below, and the cover 21 is prevented from being removed, thereby creating a translucent and reflective structure. The plate 20 is held in place.

As described above, a heat insulating air layer 20' is formed between the board 20 and the roofing material 5.

A heat insulating material 32 is installed on the support plate 30 placed on the top surface of the main building 1 at which the house components are closed, with a space 31 between it and the bottom surface of the roof material 5, and heat is radiated from this space 31 to the outside. be configured to eliminate as much as possible.

In addition, in FIG. 4 showing a cross section taken along the line IV--IV in FIG. 1, the structure of the seam of the translucent and transparent plate 20 is shown.

That is, a joint member 33 having an rH-shaped cross section is interposed between adjacent light-transmitting/shielding plates 20 and 20 to form a joint.

FIG. 3 shows an example of air circulation means attached to the air flow path in the heat receiving plate/roof structure having the above structure.

The space 31 has a distribution chamber 34 and a confluence chamber 35 at both ends.
relatively low-temperature air is sent to the distribution chamber 34 from an air supply source (not shown) through a blow pipe 36, and while passing through the space 31, it is The air is heated by heat exchange from the lower surface of the roofing material 5, which is heated to a high temperature due to the solar thermal energy applied to the roofing material 5, and the heat radiating fins 14 protruding from this lower surface, and the air is heated by the merging room. 35 and sent to a predetermined place, for example, a living room, through an air pipe 37, and used for hot air heating.

In practice, the air to the blast pipe 36 is taken from this living room,
Heating efficiency can be increased by circulating air.

The upper surface of the roof material 5 on which the heat retaining space 20' is formed forms a rain gutter during rain, and there is no risk of rainwater entering the building.

As described above, according to the present invention, although the construction is relatively rough, the roofing material and the roof structure using the roofing material can completely protect against rain.
