Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated metal panel for a roofing exterior used for a roof or an inclined outer wall surface.

2. Description of the Related Art Conventionally, there are various types and types of heat-insulating metal panels for side-roofing exteriors, and joints for receiving and flowing leaked rainwater at connection portions in the left-right direction. A member is separately attached. For this reason, the construction is time-consuming, and particularly when the joint member is inserted below the connecting portion, the work becomes particularly complicated. Naturally, the number of parts also increases.

SUMMARY OF THE INVENTION An object of the present invention is to solve this inconvenience, and to provide a metal panel for a roofing exterior having a new configuration that can be easily constructed and reduce the number of parts.

Means for Solving the Problems The present invention provides a metal plate forming a surface, a heat insulating material plate provided on the back surface of the metal plate, and only the metal plate formed on both side ends, and connected to each other during construction. A connection portion, a water return portion formed at the upper portion of the metal plate and protruding from the surface, and an engagement formed at the lower portion of the metal plate and engaging with the water return portion of another panel connected downward during construction. Department and
A heat insulating metal panel for a horizontal roofing exterior having a water receiving groove formed at one back surface position of the connecting portions of the heat insulating material plate and receiving rainwater leaking from the connecting portions.

The water receiving groove may be formed by the heat insulating material plate itself, assuming that the heat insulating material plate is made of the water-impermeable material, or may be provided with a surface layer made of the water-impermeable material on the surface. .

The connecting portion is formed of a concave groove capable of receiving and flowing rainwater, a convex portion capable of guiding rainwater and flowing, a shape formed by folding a metal plate and abutting each other, and the like. be able to.

In this panel, the insulation plate has a water receiving groove,
The construction is completed simply by connecting the panels, and the number of parts is minimized.

Examples Hereinafter, examples illustrating the present invention will be specifically described.

FIGS. 1 to 3 show a heat insulating metal panel 10 for a side-roof exterior according to a first embodiment.

 The panel 10 includes a metal plate 11 and a heat insulating plate 12.

The metal plate 11 is formed by molding a single plate of aluminum, color iron plate, stainless steel or the like. On one side, a connecting portion 13 formed of a concave groove having a substantially U-shaped cross section and becoming deeper downward is formed, and on the other side, the connecting portion 13 is overlapped and fitted on the connecting portion 13. The connection portion 14 is formed in a shape that can be used. Further, on the surface, decorative grooves 15, which have a shape substantially similar to the concave groove of the connection portion 13 and have a function of flowing rainwater and adjusting the appearance, are formed. Further, water return portions 16 and 17 are formed in the upper portion by being folded into a band shape and protruding downward from the upper surface, and the lower portion is extended diagonally downward once, and the tip is folded back, and the panel is connected downward at the time of construction. An engagement portion 18 that can be engaged with the water return portion 16 is formed.

The heat insulating material plate 12 is made of a water-impermeable material using a closed-cell foam such as styrene-maleic anhydride copolymer resin.
Is bonded to and integrated with the back surface of. A cutout 19 is formed in the lower part, and this can be overlapped with the upper part of the panel adjacent below at the time of construction. Further, at the back surface position of the connection portion 13, a water receiving groove 20 is formed in a substantially U-shaped cross section, and the back surface position of the other connection portion 14 is absent so as not to hinder the connection, and It has a shape that fits exactly into the water receiving groove 20.

The heat insulating metal panel 10 for a side-roof exterior is configured as described above, and is used and operates as follows.

The panel 10 is placed on a base material 22 and connected vertically and horizontally to form a roof. At this time, as shown in FIG. 2, the connection part in the left-right direction overlaps the connection part 14 of the adjacent panel on the connection part 13 at the time of construction and joins the end part 21 of the heat insulating material plate to the water receiving groove 20. . As shown in FIG. 3, the vertical connection portion overlaps the notch portion 19 adjacent to the water return portions 16 and 17 and the engagement portion 18 engages with the rain water return portion 16. In this way, the rainwater flows down the surface of the metal plate 11 sequentially from the upper panel to the lower part, and in particular, the concave grooves, the decorative grooves 15,
Flows mainly through 15. The rainwater leaked by the wind from the connecting portions 13 and 14 flows in the water receiving groove 20, falls inside the engaging portion 18, flows sideways, and between the adjacent right and left engaging portions 18. The metal plate of the panel adjacent to the lower part, passing through the inevitable gap
Spills on 11 Most of the rainwater that is pushed up by the wind from the top of the metal plate 11 is mostly
The very small amount of rainwater that has passed over the water return part 16 is returned by the water return part 17 and flows sideways on the water return part 16, through the gap between the left and right adjacent panels to the lower metal. It flows out onto the plate 11.

In the above example, the water receiving groove 20 is formed by the heat insulating plate 12 itself. However, like the water receiving groove 20 'shown in FIG. A configuration in which the layer 23 is provided may be adopted. In this water receiving groove 20 ', the surface layer
Because of the presence of 23, the material of the heat insulating material plate 12 may have water permeability such as an open-cell foam. The surface layer 23 may be formed from a plate material such as a vinyl chloride plate, or may be a water-impermeable film obtained by thermally melting the surface of the heat insulating material plate 12.

The connecting portions 13 and 14 are not only concave grooves as in the above example, but also are convex connecting portions 13 'and 1 shown in FIG.
4 ', the connection portions 13 "and 14" may be folded back and shown in FIG. Since the ridge guides and flows rainwater, substantially the same operation as in the case of using the concave groove can be obtained. In the case of abutting shapes, rainwater is drained exclusively by the water receiving portion.

The shapes of the water return portion and the engagement portion are arbitrary, and are not limited to those illustrated.

Effect of the Invention As described above, the heat insulating metal panel for a roofing exterior of the present invention can be connected only by the panel without using a joint member, so that the number of parts is small, the handling is easy, and the cost is low. In addition, since the work is merely required to be overlapped, it is extremely easy and efficient.

In particular, when the water receiving groove is formed by the heat insulating material plate itself, the structure becomes extremely simple, and the manufacturing can be performed easily and efficiently. In addition, if the surface layer is provided in the water receiving groove, the material of the heat insulating plate can be arbitrarily selected, so that a lower cost material can be used or a material having a higher heat insulating effect can be selected. Can respond to various requests.

Furthermore, since the water receiving groove is provided, the connecting portion does not necessarily have to have the shape considered primarily to reduce leakage. And various appearances can be realized.
