Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a roof or side wall as a solar heat absorbing outer wall for a building. 3. As this type of outer wall, a plurality of metal plates are arranged adjacent to each other. It is known that the board is fixed to the external wall support member of the building via a hanger and has means for holding a conduit for a heat transfer fluid to be heated by solar heat absorbed on the external wall surface. .

In known external walls of the type mentioned above, the plates are generally fixed at their longitudinal edges to the support member by means of hangers (also referred to as "haze").

On the other hand, the retaining means for the heat transfer fluid conduits are constituted by lip-like projections arranged between the longitudinally extending edges of each plate, which protrusions prevent rainwater from penetrating through the plates. For this reason, it may be fixed to the plate material in advance with a bonding agent or the like, or it may be integrally molded to the plate material from the beginning.
(See Publication No. 42).

For this reason, board materials cannot be used by cutting a long object wrapped around a roll into the required length at the construction site, and are instead made of panels that are pre-prepared at a factory to a fixed length that will not cause any inconvenience during transportation. has been done.

Therefore, if the length is insufficient, another similar plate must be waterproof connected to the panel-like plate.

However, such waterproof connections require additional construction costs and do not provide sufficient waterproof performance.

Hereinafter, the present invention will be described with reference to illustrated embodiments.

FIG. 1 shows an example in which the present invention is applied to the roof of a building.

This roof 10 is composed of a plurality of long copper plates 12, and each copper plate 12 has its longitudinal direction aligned with the vertical direction of the building.

In order to cover the roof shown in FIG. 1, in the embodiment shown in FIGS. 2A to 2F, the hanger 14 has a horizontal base 16, a pair of rising parts 18 projecting upward from both sides of the base 16, A pair of edges 20 are provided horizontally projecting from each rising portion 18 in opposite directions.

This hanger 14 is fixed by a fixing element 22 to a roof support member 24 of the building.

Next, a heat transfer fluid conduit 26 is placed between the rising portions 18;
Bonding agent 2 as a good thermal conductor is placed between the hanger 14 and the conduit 26
Fill 8.

Next, a plate 12 made of a copper plate having similar rising parts 30 and edges 32 formed on both sides corresponding to the rising parts 18 and edges 20 of the hanger is placed at predetermined positions on both sides of the hanger 14.

Finally, a joint plate 34 having a width approximately twice the maximum width of both edges 20 of the hanger is placed on the edge 20 of the hanger 14, and the edge 20
The part of the joining plate 34 that protrudes more laterally is bent downward to surround each edge 20° 32 of the hanger and the copper plate, and further surrounds each edge 20, 32 and the joining plate surrounding these edges. 34
Bend the parts together by about 900 degrees.

According to the construction method described above, the plate material 12 is cut into a required length at the construction site, and both longitudinal edges thereof are formed into a desired shape.

FIG. 3 shows a modification of the embodiment shown in FIGS. 2A to 2F in an assembled state.

In this example, the hanger 36 is shaped like a figure 8 and is fixed to the roof l support member 38 at its lower edge.

By deforming the vicinity of the rising part 42 of the plate material 40 made of a copper plate, the hanger 36 is deformed, and thereby the conduit 44
are securely fixed, and the hanger 36 and the plate material 40 are integrated.

In other respects, this example is substantially the same as the above embodiment.

FIG. 4 shows another embodiment for covering the roof shown in FIG.

In this example, hangers 50 having the same shape as shown in FIG. 3 are arranged not in buttons on both side edges of a plate material 46 made of a copper plate, but in a reinforcing ridge 48 formed between both side edges and projecting upward. .

Deforming the ribs 48 to deform the hanger 50 and thereby securely fixing the conduit 52 is the same as in the example of FIG. 3.

This example can also be applied additionally to the arrangement of FIG. 2 or 3.

In all of the embodiments described above, the present invention is applied to the roof of a building, but it is no secret that the present invention can make the side wall of a building solar heat absorbing.

As is clear from the above description, according to the present invention, the hanger for fixing the plate material has a function of holding the heat medium fluid conduit, and there is no need to provide conduit fixing means in advance on the plate material, so that the plate material can be used as a It is possible to use a long material that can be cut to the desired length on site.

Therefore, there is no need for panel connection work, which is required in the conventional structure, and the problem of water intrusion from the joints between panels is solved.

Furthermore, since the hanger is arranged on the back side of the board or the joint plate, the conduit fixed to the hanger can be bent into the interior of the building at any position for connection with other conduits.
