[0006]

First, regarding a copper plate, in order to solder a copper plate, a soldering solvent (flux) is applied to a portion to be soldered, and the solder melted with a trowel is sufficiently applied thereto. In this case, it is necessary to apply a soldering solvent.

On the other hand, in the case of a stainless steel plate, when welding a stainless steel plate by resistance heating, the welding position is from 1400 ° C. to 1500 ° C. Due to this high temperature,
Although the joining surface of the stainless steel plate is melted, there is a problem that the stainless steel plate is deformed at the high temperature at the same time. For this reason, the roof and wall of the stainless steel plate constructed by this method are deformed in a bellows-like manner centering on the welded portion, and the appearance is greatly impaired.

The present invention solves these problems, eliminates the need to apply a soldering solvent (flux) during construction, and joins an exterior plate for providing a stainless steel plate roof or the like with a beautiful finish. Structure.

[0009]

The exterior plate is a copper plate or a stainless steel plate, and the entire surface of the exterior plate, or at least a portion where the exterior plate is joined, is plated with solder. Then, a bonding agent in the form of a paste obtained by mixing solder powder with a soldering solvent is preliminarily applied to a joint portion of the exterior plate, a portion where the suspender and the exterior plate are joined, or the inside of the cap.

Next, at the time of construction, adjacent copper plates or stainless steel plates are braided or brought into contact with each other to bring the portions to be joined into surface contact. A top is applied to the top, and heat is applied while applying pressure. Then, the solder of the solder plating applied to the surface is melted and soldered. In this way,
Use a joint structure that is welded by soldering.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First to third embodiments of the present invention will be described with reference to FIGS. 1 to 4 using a stainless steel plate. The case of a copper plate is the same as in this embodiment.

A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing the shape of a stainless steel plate, and FIG.
FIG. 3 is a diagram showing a welding procedure. This stainless plate has been subjected to solder plating on both sides. As shown in FIG. 1, the right end of the solder-plated stainless steel plate 1 in the drawing is raised, and further folded inward at a substantially right angle to form a lower lip 3. The left end of the solder-plated stainless steel plate 1 in the drawing is first raised to form a rising portion 4, further bent outward at a substantially right angle to form a horizontal portion 5, and its tip is bent downward at a substantially right angle to form a hanging portion 6. In this way, the upper hair 2 is formed. The upper fly portion 2 and the lower fly portion 3 are assembled together.

A bonding agent 8 formed by mixing solder powder with a soldering solvent (flux) is applied to the back surface of the horizontal portion 5 of the solder-plated stainless steel plate 1 thus bent. The reason for adding the solder powder to the soldering solvent (flux) is to increase the amount of solder for soldering.

Next, as shown in FIG. 2A, the suspension upper part 7 is placed on the lower part 3 of the solder-plated stainless steel plate.
a, and the hanging element 7 is fixed to the base with nails or the like. After that, the fly portion 2 is put on the solder-plated stainless steel plate that is next to the stainless plate.

In this manner, after the upper fly portion 2, the suspender 7, and the lower fly portion 3 on which the bonding agent 8 has been applied are stacked,
(B) It is assembled like (c).

[0016] Finally, the top of the braided part 9
While pressing continuously. This topped iron
What is necessary is just a heat at which the solder melts. That is, 200 ° C
To 500 ° C. Then, the solder powder mixed with the soldering solvent of the bonding agent 8 is melted, and the upper and lower solder parts 2 and 3 are melted.
Soldering is carried out while being assembled.

If a solder powder having a melting temperature lower than that of the solder plated on the surface of the stainless steel plate is mixed with a soldering solvent to form the bonding agent 8, when the soldering iron is applied, the bonding agent 8 Although the solder powder melts and the solder is soldered, the solder plated on the surface of the stainless steel plate does not melt.

Since the stainless steel plate becomes beautiful in lead color by solder plating, the aesthetic appearance is further improved.

FIG. 3 shows a second embodiment of the present invention, in which a standing seam is roofed by using a cap 13. As shown in FIG. 3 (a), a suspender 7 is interposed between adjacent solder-plated stainless steel plates 1, and the suspender 7 is fixed to a base with nails or the like. Thereafter, as shown in FIG. 2B, a cap 13 in which a bonding agent 8 formed by mixing a soldering solvent and a solder powder into a paste is coated on the inside in advance.
And (c) and (d) will be assembled together. Finally, the braid is soldered by applying a spinning iron 9 to the braid.

Although the first and second embodiments of the present invention have been described, in these embodiments, the bonding agent may be the upper surface of the lower fly portion or the suspender if the portion is to be welded together. It may be painted on the upper surface or the back surface of the device.

FIG. 4 shows a third embodiment of the present invention, which is an example in which adjacent exterior plates are not assembled. The right and left sides of the solder-plated stainless steel plate 1 are raised to form a rising portion 4, and a bonding agent 8 is applied to the outside thereof in advance. The bonding agent 8 is obtained by mixing a solder powder with a soldering solvent (flux), as in the above-described embodiments. The solder-plated stainless steel plates 1 formed as described above are arranged side by side as shown in FIG. 3B, and the suspension 7 is sandwiched therebetween. The suspender 7 is fixed to the ground with nails or the like. Thereafter, a top-like iron is applied to the rising portions 4.4 sandwiching the suspension 7 while continuously applying pressure as shown in FIG. In this way, they are joined by soldering.

In this embodiment, the bonding agent 8 is applied to the rising portion 4. However, the bonding agent 8 may be applied to the upper part of both sides of the hanging member 7 as in the first and second embodiments.

[0023]

According to the joint structure of the armor plate according to the present invention,
The joining can be performed at 200 ° C. to 500 ° C., which is an appropriate temperature for soldering, and is much lower than the temperature of 1400 ° C. to 1500 ° C. which has been conventionally used for welding stainless steel by resistance heating. As a result, the stainless steel plate does not deform due to temperature, and
Can provide walls.

[0024] Regarding the construction, since a glue-like joining agent obtained by mixing a soldering powder with a soldering solvent is used, it can be shipped after applying it to a joint of an exterior plate at a factory. In this way, the work on site can be done simply by brazing the outer plate and applying a top-like iron, so there is no need to apply a soldering solvent (flux) during the work. Can be omitted. Of course, there are cases where a molding machine is carried into the site and the molding process is carried out. However, even in this case, the bonding agent can be applied while processing, so there is no need to apply a soldering solvent (flux) during construction. be able to.

Then, the glue formed by mixing the solder powder with the soldering solvent becomes a bulking agent that increases the amount of solder when soldering, and can be soldered firmly.

Further, since the portion coated with the soldering solvent is located inside the fly, it is not exposed to the wind and rain after the application, and exhibits a long term welding force.

In addition, the joint structure according to the present invention can prevent rainwater from entering because the joint is entirely soldered.
