And the connecting portions of the adjacent unit component plates are locally connected in a portion where these unit component plates are partially overlapped with each other. "

る。According to the above-mentioned means, each unit component plate constituting the heat shield plate (2) is connected only at the local connection portion, and the portions other than the local connection portion are in the non-connection state. It has become. Therefore, when attention is paid to a specific unit component plate that thermally expands, the deformation force of the unit component plate due to thermal expansion is transmitted to the adjacent unit component plate only through the local coupling part, and the local coupling is performed. In the non-connection region where the unit component plates other than the part are not connected to each other, since the thermal expansion can be freely performed, the deformation force is not transmitted to the adjacent unit component plates,
To that extent, it becomes difficult for the deformation force to be transmitted to the outer peripheral portion of the heat shield plate (2).

As in the invention according to claim 2, "the locally coupled portion is formed by a caulking hole formed in one of the unit component plates that are overlapped with each other, and the other portion that is overlapped by the one unit component plate. And a caulking projection formed by partially projecting and protruding from the unit component plate and being caulked by being inserted into the caulking hole '', for a caulking hole formed on one of the unit component plates, Since the caulking projection partially protruded from the other unit component plate is caulked, a through-hole penetrating from the front to the back, that is, a through-hole causing heat leakage is not formed in the caulking portion.

It is transmitted to the adjacent unit component plate via one caulking point.

難くなる。As described above, according to the first to third aspects of the present invention, the deformation force of each of the thermally expanding unit component plates is reduced by the heat shielding plate.
Since it is difficult to transmit to the outer peripheral portion of (2), for example, the heat shield plate (2)
Even if the peripheral part of is fixed to the mounting target part with screws etc.
It becomes difficult for the deformation force of the heat shield plate (2) due to the thermal expansion to be transmitted to the attachment target portion, and the attachment target portion is not adversely affected.

There is less fear that the heat shield plate (2) will come into contact with the mounting target portion, and there is no problem that heat is directly transmitted to the mounting target portion. Since the whole heat shield plate (2) is not composed of a single metal plate, but composed of multiple unit component plates,
For example, it can be manufactured by connecting a circular plate, a rectangular plate, or the like as a punching waste generated when a metal plate is press-punched, and it is possible to effectively use a plate material that has been disposed of as a scrap.

層伝わり難くなる。According to the second aspect of the present invention, the heat insulating effect of the heat shield plate (2) is improved because the through hole which causes the leakage of heat is not formed in the swaged portion of each unit component plate. According to the third aspect of the present invention, since the deformation force of each unit component plate is transmitted to the adjacent unit component plates via a single caulking point, the adjacent unit component plates are caulked at a plurality of locations. As compared with the above, the number of transmission paths of the deformation force is reduced, and the deformation force is more difficult to be transmitted.

くなる。In this case, the first heat shield plate (2)
As shown in FIG. 5, the third unit component plates (21), (22), and (23) are connected only at one caulking joint (35) (35), and the caulking joint (35) Portions other than (35) are in an unconnected state as shown in FIG. Therefore, for example, when the first unit component plate (21) and the second unit component plate (22) thermally expand, in a non-connection region where they are not caulked,
As shown by the imaginary line in FIG. 7, the first and second unit component plates (21) (2)
The peripheral portions (219) and (229) of (2) extend and contract independently of each other. Therefore, in this region, since the thermal expansion is performed freely, the deformation force due to the thermal expansion of the first unit component plate (21) or the second unit component plate (22) is reduced by another second unit component plate (22) or the second unit component plate (22). The deformation near the region is not transmitted to the one-unit component plate (21), and
It is absorbed by the unit component plates (21) and (22) themselves. Therefore,
The adverse effect of thermal expansion of the heat shield (2) is due to the screws (16) (16) and the mounting feet.
(15) It is difficult to transmit to the back plate (110) side via (15), and the back plate (110) is less likely to be deformed by the action of an excessive force.

喪失の不都合が防止できる。Further, as described above, in the unconnected region of the first unit component plate (21) and the second unit component plate (22), the deformation due to the thermal expansion is caused by the other second unit component plate (22) and the second unit component plate (22). Since it is not transmitted to the one-unit component plate (21), the deformation of the heat shield plate (2) itself is reduced. When the gap between the heat shield plate (2) and the back plate (110) is reduced for compactness (for example, about 2 mm)
However, it is possible to prevent the heat shield plate (2) from being deformed and coming into contact with the back plate (110), and the heat shield plate (2) comes into contact with the back plate (110) and heat is transferred thereto. As a result, the inconvenience of loss of function of the heat shield plate (2) can be prevented.

Since (23) is formed by connecting, even if it is a small scrap material such as a disc-shaped scrap generated when a through hole for a gas burner formed in the top plate of the table stove is pressed and pressed, This can be used effectively to make the heat shield (2). FIG. 9 shows an example in which the heat shield plate (2) is used to shield heat between the heat exchanger of the water heater and the casing (11). It can be used as various heat shields, as in the case where the space is thermally shut off.

The heat shield plate (12) is fixed to the back plate (110) with screws (16) (16), but the heat shield plate (12) is attached without mounting feet (15) (15). The screws (16) (16) may be directly attached to the rear plate (110). In the above embodiment, the second and third unit component plates are used.

Since each unit component plate is caulked using (235), the caulking operation and the bending and punching operations of the periphery of the heat shield plate (2) can be performed simultaneously by a press machine. Therefore, the workability is improved as compared with the case where the unit component plates are joined by spot welding and then bent or the like. Also, unlike the case of using the rivet, a special member (rivet) for caulking becomes unnecessary, and the number of parts can be reduced.
