Description

[Detailed description of the invention] [Industrial application field] The present invention mainly relates to a metal exterior body with a new configuration that constitutes roofs and walls. The present invention relates to a metal exterior body with a new structure that enables efficient construction and prevents so-called "rust" by applying a weldable coating to a metal plate such as a stainless steel plate in advance on the wall.

[Conventional technology]

Recently, with metal plates, especially stainless steel plates,
When configuring roofs and walls, movable hangers are interposed at predetermined intervals between the raised ends of adjacent joints to accommodate the thermal expansion and contraction of the metal plates, and seam welding is performed along the entire length of the ends. Techniques have been developed to perform this process and apply a metal exterior body.

During on-site construction, this metal exterior body is constructed by seam welding the adjacent raised end portions, then applying a non-conductive primer coating to the surface of the metal plate, leaving the seam welded area, and after this coating dries. The entire surface is treated with a top coat of paint.

Now, to explain this conventional example with reference to FIGS. 7 and 8, movable hangers e are interposed at predetermined intervals between the end portions c and d of the facings a and b of adjacent stainless steel plates. and a seam weld f is applied to the entire length of the raised end portion to be joined.

After performing the seam weld f, a non-conductive primer g is applied to the surfaces of the face materials a and b, leaving the seam weld part f, and after waiting for this paint to dry,
The entire surface is coated with top coating.

[Problem that the invention attempts to solve]

In the above-mentioned conventional example, in the on-site construction, the primer coating g is applied, and then the top coating h is applied.

Therefore, on-site construction must be suspended until the primer coating g dries.
The disadvantage is that construction takes a long time.

In addition, this primer coating g is seam welded f to the end upright parts c and d as the next step after on-site construction.
Since the seam welding is carried out by leaving the seam weld f after applying the above, it is difficult to paint the areas near the raised end parts c and d, and uniform painting becomes even more difficult due to the work involved in high places. be.

Furthermore, in the conventional example, since painting is a later process, so-called "rust" may occur during work or storage, which poses a problem in the intended waterproof structure.

[Means and actions for solving problems]

This invention was created in view of the above points, and by applying the conventional on-site primer coating to the stainless steel plate surface material in advance, it improves efficiency and prevents damage during work or storage. The purpose of the present invention is to provide a metal exterior body whose purpose is to prevent "rust" and protect the surface of the facing material.

In order to achieve this purpose, the present invention applies a weldable conductive primer coating to the surface in advance, and then
The facing parts of the top-coated stainless steel plates are connected one after another, leaving the parts to be welded, that is, the raised parts of each end in the longitudinal direction or the width direction, and the predetermined parts are attached to these adjacent raised parts of the ends. The gist of this method is to weld the respective face materials to form a joint structure.

Therefore, it is possible to improve work efficiency during on-site construction and protect the surface of the facing material.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a long face material made of a corrugated stainless steel plate 2, and as shown in the first figure, a conductive primer coating 3 that can be welded to the surface of the stainless steel plate 2 is applied before construction, and then Top coating 6 is applied except for the welded portions to be applied to the end upright portions 4 and 5 in order to join adjacent panels 1 together.

That is, the conductive primer coating 3 is applied to the entire surface of the stainless steel plate 2. In contrast,
Top coating 6 applied to 3 conductive primer coating surfaces
As mentioned above, in order to join the adjacent face materials 1, they are painted, leaving the upright portions 4 and 5 at each end in the longitudinal direction, which will be later molded and welded.

Although not shown, the stainless steel plate 2
Similarly, the raised portions at each end in the width direction are not top coated, but welded to join the adjacent face members 1 in the width direction.

These conductive primer coatings 3 and top coatings 6
As the coating material, any commercially available synthetic resin-based material can be used.

As shown in Figure 4, the stainless steel plate 2 is provided with one or several protrusions 2a (in the figure, one) of an arbitrary shape along the longitudinal direction in the central part to increase strength and reduce plate noise. It is also possible to configure the surface material 1' to prevent such damage and enhance the aesthetic appearance.

In this face material 1', the top coating 6 is not applied to the protrusion 2a. In other words, in the final step after a predetermined welding process is performed using a suspender having a movable piece, which will be described below, the surface of the protrusion 2a is top coated. .

A roof, walls, etc. are constructed using the panel material 1 having such a configuration in a conventional manner, and an example of the roof shown in FIG. 5 will be described.

First, the hanger 7 having a movable piece 8 that can move within a certain range in response to thermal expansion and contraction of the panel 1 will be described.

This hanger 7 only needs to have a movable piece 8 that corresponds to the thermal expansion and contraction of the face material 1 as described above, and hangers other than those shown in FIG. 6 can be used.

Reference numeral 9 denotes a raised substrate, which is bent and formed with a rising portion 10 projecting in the longitudinal direction approximately at the center;
A long hole 11 is formed in the substrate 9 along the lower end of the substrate 9.

By wrapping the lower end portion 12 around the rising portion 10 and arranging the movable piece 8 in an upright manner, the movable piece 8 is configured to move within the range of the elongated hole 11. 13 is a joint of the movable piece 8, and 14 is a tightening hole.

As shown in FIG.
A face material 1 whose tip end is folded back and molded into a bent portion 5a is placed on the structure 15. Then, hangers 7 are arranged at predetermined intervals below each of the end upstanding parts 4 and 5, and the hangers 7 are fixed to the structure 15 through the tightening holes 14 with screws 16.

Next, the facing materials 1a and 1b are arranged next to the facing material 1 so that the end upstanding portions 4 and 5 are in contact with each other, the joint portion 13 of the movable piece 7 of the hanger 7 is interposed, and the After the abutting end upstanding portions 4 and 5 are caulked so that the portion 5a fits over the upper end of the end upstanding portion 4, spot welding or seam welding 18 is applied to the entire length of the caulked portion 17, respectively.

Further, this welding 18 can be performed only at the caulking point where the movable piece 8 of the hanger 7 is interposed between the end standing portions 4 and 5, but in consideration of strength, waterproofness, etc. It is desirable to apply the coating to the entire length of the portion 17.

Then, the caulking portion 1 at the bent portion 5a of the upper end portion
A roof can be constructed by performing seam welding 19 on 7 and finally applying top coating to this caulked portion 17.

[Effect of idea]

In this way, the metal exterior body of the present invention is manufactured by applying a weldable conductive primer coating 3 to the surface of the stainless steel plate 1 in advance in the process before on-site construction, and then applying a top coating 6 to the surface of the stainless steel plate 1, leaving only the welding area. Gone material 1
can be used.

For this reason, in on-site construction as in the conventional example,
After welding adjacent panels, the process of applying a non-conductive primer to the stainless steel plate can be omitted, and by pre-coating in advance, the work at high places required for on-site primer painting can be avoided. In particular, the drying time of primer coating can be omitted,
You can measure the improvement of work efficiency.

In addition, there is no need to forget to apply the primer, and the process of applying a large area can be carried out more efficiently.

Furthermore, in the conventional example, metal plates such as stainless steel plates sometimes developed so-called "rust" during work or storage, but in the present invention, the surface is coated with a conductive primer.
It has the advantage of protecting the scalp and eliminating the need for later processing to remove rust.
