Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a metal composite panel in which a metal plate is fixed as a decorative plate to the surface of an inorganic panel. In particular, inorganic panels, which have excellent insulation properties and are in high demand in recent years,
For example, it relates to a metal composite panel that has both heat insulation and design properties by fixing a metal plate to the surface of a lightweight aerated concrete plate.

[Conventional technology]

Generally, in a conventional metal composite panel in which a metal plate is fixed as a decorative plate to the surface of an inorganic panel, the entire edge of the panel is also covered with a metal plate in order to ensure waterproofing of the edge of the panel. During construction, metal composite panels were attached with gaps between them to form a sealing joint.

In addition, in conventional metal composite panels, the metal plate is a decorative board and also serves as a finishing material, so it cannot be fixed with screws or the like from above the metal plate on the panel surface.
Special measures have been taken for installation. For example, as shown in FIG. 5, a plurality of mounting pieces 15 are attached to a metal plate 14 that also covers the edge surface, so that screws can be secured and a mounting structure that is waterproof and fits well can be achieved. It is known that this mounting piece 15 is fixed to the base steel frame 17 using tapping screws 16 to provide a mounting structure that is waterproof and can be easily accommodated.

[The problem that the idea attempts to solve]

However, this conventional inorganic metal composite panel also
As described above, during construction, the metal composite panels are attached with spaces between them to form a sealing joint. However, when such a gap exists where no panel exists, there are problems such as the gap becoming a weak point in the event of a fire or a heat bridge. In addition, if all edges around the panel were covered with metal plates, there was a drawback that dimensional adjustment by cutting at the construction site was completely impossible.

The object of the present invention is to provide a metal composite panel that can be installed using screws, is easy to install with inorganic panels facing each other, and is easy to adjust dimensions in at least one direction. do.

[Means to solve the problem]

The present invention provides a metal composite panel in which a metal plate is fixed to the surface of an inorganic panel. (b)
In the upper notch having an L-shaped cross section, a metal plate existing on the panel surface is bent along the shape of the notch, and (c) on the side surface of the lower side where there is no notch, A metal plate bent to a length corresponding to the depth of the notch with an L-shaped cross section on the upper side protrudes from the panel except for the center part of the lower side; In the notch with an L-shaped cross section, there is a metal plate bent to a length corresponding to the depth of the notch, but in the part parallel to the panel surface of the notch with an L-shaped cross section, This is a metal composite panel characterized by the fact that there is no

The inorganic panels used in this invention include:
In addition to aerated concrete boards such as ALC boards,
Examples include PC boards, Keikal boards, asbestos cement boards, and wood cement boards. In addition, when it is assumed that the metal composite panel of the present invention is installed using tapping screws, the inorganic panel must be a thin panel reinforced with lath netting, etc., such as a thin ALC reinforced with lath netting, etc. is preferred.

Further, as the metal plate, a metal plate whose surface is decorated, such as an enameled steel plate or a fluororesin steel plate, is preferably used.

Furthermore, a synthetic resin adhesive is preferably used to fix the metal plate to the inorganic panel.

[Effect of invention]

The metal composite panel of the present invention has (a) an L-shaped cutout in cross section along the entire length of the side in the upper and right three peripheral areas of the inorganic panel surface, and (b) a cutout in the upper cross section. In the L-shaped notch, the metal plate existing on the panel surface is bent along the shape of the notch, and (c) the side surface of the lower side where there is no notch is bent on the upper side. By adopting a structure in which a metal plate is bent to a length corresponding to the notch depth of the cutout part with an L-shaped cross section and protrudes from the panel except for the center part of the lower side, the following can be achieved. exerts its effect.

Firstly, when installing the metal composite panels of the present invention one above the other, the inorganic panels can be placed against each other, which can be a weak point in the event of a fire or cause a heat bridge, unlike when installing conventional panels. There are no gaps between the inorganic panels, which can cause problems such as cracking.

Second, even if the metal plate is constructed as described above, there will be no problem in construction since the metal plate is constructed as shown in (b) and (c) above. In other words, by adopting the configuration shown in (b), first insert a screw or the like at the center of the mounting side (notch parallel to the panel) of the notch with an L-shaped cross section at the top of the first metal composite panel to be attached below. The metal composite panel can be used to penetrate a metal plate or an inorganic panel and temporarily fasten it to a rim or the like, and then a second metal composite panel can be positioned above this panel so that the upper and lower inorganic panels are in contact with each other. Then, the above
By adopting the configuration of (c), the second panel placed above is placed on the metal plate existing on the surface of the notch above the first metal composite panel placed below. It has a structure in which metal plates protruding downward overlap. Therefore, the metal plate protruding below the second panel of the overlapping metal plates (i.e.
Using screws, etc., from above (the metal plate with no metal plate protruding from the center of the lower side corresponding to the overlapping part), attach the metal plate to the upper notch of the first panel that is on the lower side. Penetrate through the inorganic panel and fix to the frame, etc. In this way, it is possible to fix both the upper and lower metal plates at once.

Furthermore, even after fixing the second panel in this way, the heads of the screws temporarily fastened at the center of the top of the first panel are visible, so make sure to firmly fix the screws. This makes it possible to fix screws at the same height with the same tightening level.

Furthermore, since the mounting portion where the screw is driven is formed into a stepped portion with a notch, it can be used as a sealing joint, and it is possible to prevent problems in terms of waterproofing.

Thirdly, the metal composite panel of the present invention has the configuration (d), so that the inorganic panels of the metal composite panel can be installed without any gaps not only in the vertical direction but also in the horizontal direction, and also in the left and right directions. It becomes possible to create a sealing joint using the letter-shaped stepped portion.
Therefore, as described above, it is possible to avoid problems in the event of a fire or problems in waterproofing that occur when constructing panels of the prior art.

Furthermore, since the panel of the present invention does not have a metal plate in the horizontal position of the left and right notches, it is easy to adjust the width dimension by cutting out these parts with a plane or the like at the construction site.

In addition, in the metal composite panel of the present invention, the panel surface of the metal plate is bent along the shape of the notch having an L-shaped cross section on the upper side, which is the side opposite to the side where the notch does not exist. The existing width should be the same as the notch width, and the width of the metal plate on the mounting side protruding from the side panel on the lower side should be the width corresponding to the notch width of the L-shaped cross-sectional notch on the top side. is preferred. However, if it is anticipated that the top and bottom lengths of the panel will not match the spacing between the edges, etc. at the site, it is possible to make the protrusion on the cutout side of the top of the inorganic panel protrude beyond the metal plate.
In addition to cutting the protruding length of the metal plate that protrudes in the opposite direction along the lower side, the side of the inorganic panel on the upper side can be cut with a plane or the like, making it possible to adjust the vertical dimensions.

〔Example〕

The present invention will be explained below by showing one embodiment thereof.

FIG. 1 is a diagram showing an embodiment of the metal composite panel of the present invention, and FIG. 2 is a diagram showing details of the main parts of FIG. 1. In order to clearly distinguish between the inorganic panel and the metal plate, the metal plate is shown with a broken line in these figures.

In these figures, as inorganic panel 1
An ALC board is used, and the peripheral part of the panel surface on the left and right sides 3 and 4 of the panel 1 has a structure in which an L-shaped notch 7 exists along the entire length of the side. , while the upper side of the panel 5
The peripheral part of the side panel surface is L over the entire length of the side.
It has a structure in which a notch portion 7' cut out in the shape of a shape exists, and a structure in which there is no notch on the panel surface on the side surface 6 side on the lower side of the panel.

Further, the corner portions of the panel surface side of each of the cutout portions 7, 7' of the panel are cut out so that the metal plate 2 can be easily covered.

On the other hand, the metal plate 2 is formed by drawing the side corners of the metal plate 2 along the notch side surfaces of the notch portions 7 and 7' of the panel 1 and the panel side surface 6 where the notch portions do not exist. is bent into a box shape,
Furthermore, the metal plate 2 is bent into an L-shaped cross section on the notch 7' on the upper side and on the side surface 6 on the lower side of the panel where no notch exists. .

In addition, the mounting side 8 that is bent above the notch 7' on the upper side has a metal plate mounting side 8 along the entire length of the side, and screw holes 9 are provided at both ends and in the center. On the other hand, the mounting side 8' protruding from the lower side of the panel is cut out at the center and has screw holes 9 at both ends.

In this way, the metal composite panel of the present invention has a box-shaped metal plate 2 having bent mounting sides 8 and 8', and the mounting sides 8 and 8' are the upper sides of the inorganic panel 1, respectively. 5 so that it is on the side 6 of the notch 7' and the bottom side without the notch,
It has a structure in which it is integrally fixed to an inorganic panel 1 with a synthetic resin adhesive.

The attachment of the metal composite panel of the present invention to the wall of a building will be explained with reference to FIGS. 3 and 4B. First, the first metal composite panel 20 placed on the lower side is inserted into the center screw hole of the mounting side 8 on the upper side using a driving screw such as a tapping screw to penetrate the inorganic panel under the metal plate. It is temporarily attached to the rim 10 and the like, and then the second metal composite panel 19 is positioned above this panel so that the upper and lower inorganic panels are in contact with each other. Then, the lower panel 2 is placed under the protruding mounting edge 8' on the lower side of the upper panel 19.
The mounting side 8 on the top side of 0 will fit in. In this state, after temporarily fixing the upper side of the upper panel 19 to the rim 10 etc. using screws, the upper panel 19
With the lower mounting side 8' of the lower panel 20 and the upper mounting side 8 of the lower panel 20 overlapped, use a screw such as a tapping screw to drive the lower side from above the overlapping mounting side 8'. It pierces through the inorganic panel on the upper side of the panel 20 and is fixed to the rim or the like.

In addition, after fixing in this way, there is no protruding metal plate in the center of the lower mounting side 8' of the panel, so the head of the screw temporarily fastened at the center of the upper side of the panel 20 attached to the lower side is visible. This allows the screws to be firmly fixed, and screws at the same height can be tightened to the same degree.

Next, FIG. 4A is a sectional view showing a vertical joint portion when a wall surface is constructed by attaching the metal composite panel of the present invention so that the left and right side surfaces of the inorganic panel are in contact with each other. As shown in FIGS. 1 and 2, on both sides 3 and 4 of the panel of the present invention, where the notch 7 is present, the metal plate 2 is only on the side surface of the notch 7. Since it does not exist, it becomes possible to directly butt the inorganic panels against each other. Further, the dimensions can be adjusted by cutting the inorganic panel at this protruding portion with a plane or the like.

Then, when the panels are joined at the left and right sides, as shown in FIG. 4A, the stepped part created by the notch in both panels can be made into a vertical joint, and the sealant 12 is embedded in this part. The sealing joint 18 can be configured with this. Therefore, even if the vertical joint portion is a structure in which metal composite panels are simply butted against each other, it is possible to completely waterproof the edge portion.

On the other hand, as shown in FIG. 4B, there is also a step between the upper and lower metal composite panels 19 and 20 installed as described above due to the presence of the notch 7' on the upper side of the lower panel 20. There is. This stepped portion constitutes a horizontal joint 18. This horizontal joint 1
On the surface of 8, there are mounting sides 8 and 8' for the metal plates, and the joints 18 can be sealed and treated with a sealant 12 on top of them.
Complete waterproofing is possible.

The above example has been explained in which the metal composite panel of the present invention is attached to a frame, but the above example can also be followed when attaching it to a stud or the like.

[Effect of idea]

Since the metal composite panel of the present invention has the structure described in the claims, it can be constructed by abutting the inorganic panels on the top, bottom, left and right sides with no gaps between them, eliminating weak points in the event of a fire between the panels and creating a heat bridge. never occurs.

In addition, since the metal composite panel of the present invention has cutouts on the top side and left and right sides, it is possible to form vertical sealing joints and horizontal sealing joints using these parts. It also prevents horizontal and waterproof problems from occurring.

Furthermore, even if the metal composite panels of the present invention are installed with the panels facing each other, the protruding metal plate portion that is bent to have an L-shaped cross section will overlap the cutout portion of the other panel that has an L-shaped cross section. It becomes possible to attach by driving screws such as tapping screws into the overlapping parts of the plates.

Furthermore, since there is no metal plate in the center of the metal plate of the mounting part that protrudes from the side of the bottom side of the panel, the screws etc. in the center of the top side of the panel located on the bottom side that were temporarily attached first can be seen from the surface. By driving a screw such as a tapping screw into the overlapped portion of the metal plates, the metal plates on both sides can be fixed at once, and then this temporary fixing can be fully tightened and fixed.

Furthermore, since there is no metal plate in the left and right step portions corresponding to these width surfaces, it is easy to cut out these portions with a plane or the like at the construction site to adjust the dimensions.
