Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an improvement of a roof structure that actively contributes to the utilization of solar heat, and which has a simple structure and is useful for energy saving by effectively utilizing solar energy. The purpose is to

[Conventional technology]

Most of the conventional solar heat utilization devices are simply arranged pre-framed solar heat collection devices on a general roof with only rain protection in mind, and when arranging the solar heat utilization devices A version without a roof plate has also been proposed.

[Problem that the invention seeks to solve]

In any case, in the case of conventional types, the rain-shedding performance of the pre-framed heat collection device itself as a roofing material has not been sufficiently considered, and many problems remain that need to be solved during construction. has been done.

[Means for solving problems]

Here, the present invention provides a plurality of projecting edges for supporting a light-transmitting plate on the upper surface of a roof material made of an extruded section, a plurality of tube receivers on the lower surface, and an L-shaped mounting piece and a light-transmitting plate mounting piece on both sides. A placing part is provided continuously in the longitudinal direction of each of the roofing materials, these roofing materials are arranged along the slope direction of the roof, and a transparent plate is mounted on the transparent plate placing part, and the roofing materials are placed next to each other. Lay the lower parts of the roofing material attachment pieces on top of each other and fasten them together, and engage the hook part of the cover by straddling these two attachment pieces to the shoulder provided on the upper part of the upright part of both attachment pieces. This paper proposes a roof structure that is characterized by the fact that

[Effect]

The present invention will be explained below with reference to the accompanying drawings.

In Figures 1 and 2, 1 is the main building;
This main building 1 is supported by pillars 3 via beams 2 (Fig. 2). Roofing materials 5 are successively placed between the rafters 4 installed in a direction substantially perpendicular to the main building 1. This roofing material 5 is made of an extruded aluminum alloy section, and a lower piece is attached to one end as an attachment part. A mounting piece 6 having a substantially L-shape is formed by a portion 6a and an upright portion 6b, and a lower piece 7a shaped to fit into the lower piece 6b of this mounting piece 6 at the other end. An attachment piece 7 formed into a substantially L-shape with the upright portion 7b is formed as an attachment portion. Packing seats 8 and 9 are protruded from the upper surface of both ends of the roof material 5 in the vicinity of the L-shaped mounting pieces 6 and 7, and packing seats 8 and 9 are fitted with packing seats 10 and 11, respectively. A transparent plate mounting section is formed. Further, on the upper surface of the roofing material 5, a plurality of protruding edges 12 are provided at intervals from each other to support light-transmitting plates, which will be described later. Provide an absorbing surface (high absorption of heat rays and low radiation). A plurality of pipe receiving parts 14 are provided on the lower surface of the roofing material 5 at intervals, and the upright parts 6b and 7b of the mounting pieces 6 and 7 at both ends are provided with roofing material from their tops. Shoulders 15, 16 extending laterally toward the center of the rainwater filter 5, and rainwater returns 17, 18 connected to these shoulders 15, 16 and extending obliquely upward are formed.

When attaching the roofing material 5 to the rafters 4,
In the adjacent roof materials 5, 5, the lower piece 6a of the attachment piece 6 on one end side is attached to the attachment piece 7 on the other end side.
Overlap the lower pieces 7a of the mounting bolts 1
Both mounting pieces 6, 7 are fixed to the rafter 4 by fastening them together at 9.

Next, a transparent plate 2 is placed between the packings 10 and 11.
0 is placed thereon, and the cover 21, which is a bar-shaped member formed in a gate shape, is placed over the mounting pieces 6 and 7 and fixed. Packing 2 fitted into the formed packing seats 24 and 25
The transparent plate 20 is held between the packings 6, 27 and the packings 10, 11, and this state is maintained as follows. That is, the hanging edges 22, 2
Hook parts 28 and 29 extending diagonally upward from 3 are
The transparent plate 20 is held in a fixed position by being hooked onto the shoulders 15 and 16 from below and preventing the cover 21 from being pulled out. The pipe receiving portion 14 supports the water pipes 30 through which the heat medium passes, and in this case, if the water passing through the water pipes 30 is to be used for drinking, copper pipes are used, and in other cases, generally uses aluminum tubes. In some cases, as shown in FIG.
By constructing the hollow section 5' with a hollow section 5', it is possible to consider using the hollow section 5'' of the section 5' as a water pipe.

A heat insulating material 32 is installed between the support plate 31 disposed on the upper surface of the main building 1 and the lower surface of the roof material 5 to improve heat retention. In addition, - in Figure 1
In FIG. 5, which shows a cross section taken along a line, the structure of the seam of the transparent plate 20 is shown. That is, a joint member 33 having a substantially H-shaped cross section is interposed between adjacent light-transmitting plates 20, 20 to process the joint.

FIG. 3 shows an example of a water flow system for the heat-receiving plate/roof structure constructed as described above. Said water pipe 3
0 are connected by headers 34 and 35 at both ends, one header 34 is press-fitted with cold water via a water supply pipe 36, and the other header 35 is
From there, a water pipe 37 is led out to deliver hot water to the required locations.

In practical use, the roofing material 5 is heated by solar heat that passes through the transparent plate 20 and reaches the black surface 13 as a heat ray absorbing surface of the roofing material 5, and the heat energy is transferred from the roofing material 5 to the water pipe. 30, the cold water is transmitted through the water pipes 30 to the water flowing through the water pipes 30, and thus the cold water becomes hot water and is sent out from the water pipe 37, and this hot water is used for heating or hot water supply. .

〔Effect of the invention〕

According to the roof structure of the present invention having the above configuration, the following effects can be obtained. In other words, since the roofing material is an extruded shape, it is possible to freely form a plurality of projecting edges on the top surface and a plurality of pipe receivers on the bottom surface in the longitudinal direction of the roofing material, and to support the transparent plate on the top surface. , it is extremely easy to hold the water pipe on the bottom surface.

Furthermore, since the L-shaped mounting piece and the transparent plate mounting portion can be integrally molded, the number of component parts can be reduced and assembly work can be performed easily.

The translucent plate is supported not only at both ends but also at the middle by the protruding edges, so it is supported more stably.
Enables people to walk on transparent boards during construction and repair.

The space between the translucent plate and the roofing material is divided into multiple sections by the ridges, so convection within the space is reduced, and the heat collected by the roofing material is radiated through convection within the space. Loss will be reduced.

Since the light-transmitting plate is held between the roofing material and the cover, which is a stick member, it is supported more reliably.

By circulating water through the water pipe, hot water can be obtained, and this hot water can be used for heating or hot water supply as appropriate, and since the water pipe is passed inside the roofing material, it can be collected easily. Heat efficiency can also be maintained at a high level.
