Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior metal panel used in construction and a method for manufacturing the same.

2. Description of the Related Art Clad steel such as titanium, aluminum, copper, or a metal of these and other iron, steel, stainless steel is expensive, but not only excellent in corrosion resistance but also excellent in design and workability. Therefore, there is a proposal to make use of this characteristic as an exterior panel for construction. The one introduced in FIG. 9 is an example. In order to increase the panel area, this panel 1 is a thin (1.5 mm thick) titanium panel 2, a backing plate 3 made of a channel-shaped calcium silicate plate, and a SUS plate.
It is reinforced by an edge made of a reinforcing frame 4. The titanium panel 2 and the backing plate 3 are bonded together with an organic adhesive, and the titanium panel 1 and the SUS reinforcing frame 4 are integrated by bolting 5. . Also, the backing plate 3 and the SUS reinforcement frame 4
The bolts 6 are also coupled with the bolts 6, but the bolts 6 also serve to attach the panel 1 to the attachment jig 8 that is attached to the body 7.

The above conventional panel has the following problems. (1) It is anxious to entrust the unreliable organic adhesive to integrate the panel 2 and the backing plate 3 because they are exposed to severe outside air conditions. (2) Since the backing plate 3 and the reinforcing frame 4 that reinforce the panel 2 are designed to share the mutual integral fastening portion and the fastening portion between the pair of mounting jigs 8 within their thickness, the thickness of the reinforcing material can be reduced. ， It is difficult to obtain effective reinforcement within a limited thickness because it causes the reinforcement frame to be missing. (3) The titanium panel 2 and the SUS reinforcing frame 4 are integrated by bolting 6. This method requires anti-corrosion measures in the titanium / SUS gap and titanium / bolt gap, which complicates the panel mounting structure and on-site construction method. (4) Since the end of the panel 2 is exposed to the outside air and is adjacent to the dissimilar metal body, the adhesion of water may cause the end corrosion. (5) Since the backing plate 3 is a standard material, the panel 2 attached to this with an adhesive is 1.5 mm to ensure a predetermined rigidity, but it is unnecessary from the viewpoint of corrosion resistance and decoration. It is thick and expensive. The present invention has been made in view of the above problems of the conventional art, and an object thereof is to provide a lining that can be involved in all of its thickness under weatherproof integration. An object of the present invention is to provide a metal panel for exterior and a manufacturing method thereof, which is for reinforcement and can reduce the thickness of the metal panel without the risk of corrosion occurring at the edge of the metal panel or the panel mounting portion.

In order to achieve the above object, an exterior metal panel according to the present invention is provided with a corrosion resistant metal such as titanium, aluminum or copper, or an end portion of a clad thin plate of these metals and another metal. Cement for adding fire resistance, sound insulation, heat insulation, strength, and rigidity to ordinary mortar, carbon fiber reinforced mortar, etc. This is a product in which a system filler is filled and a building attachment jig is buried in the filler. On the back side of the face plate that is box-shaped by end-to-end welding processing after bending the end of the clad thin plate of corrosion-resistant metal such as titanium, aluminum or copper or these metals and other metal into the state in which the tip is rolled inward, A reinforcing coffin material is provided to give strength and rigidity to the face plate, and a cement-based filler for imparting fire resistance, sound insulation, heat insulation, strength and rigidity such as mortar or carbon fiber reinforced mortar is usually filled. The building mounting jig is erected on the reinforcing rod material. On the back side of the face plate that is box-shaped by end-to-end welding processing after bending the end of the clad thin plate of corrosion-resistant metal such as titanium, aluminum or copper or these metals and other metal into the state in which the tip is rolled inward, In addition to arranging a reinforcing rod material for giving strength and rigidity to the face plate and a stat bolt for mechanical joining of filler material, fire resistance, sound insulation, heat insulation, strength of ordinary mortar and carbon fiber reinforced mortar etc. A cement-based filler for imparting rigidity is filled, and a building attachment jig is erected on the reinforcing rod. On the back side of the face plate that is box-shaped by end-to-end welding processing after bending the end of the clad thin plate of corrosion-resistant metal such as titanium, aluminum or copper or these metals and other metal into the state in which the tip is rolled inward, A honeycomb for joining surface accuracy and durability of the face plate is joined, and a cement-based filler for imparting fire resistance, sound insulation, heat insulation, strength, and rigidity such as mortar or carbon fiber reinforced mortar is filled, and installed in a building. The jig is buried in the filling material. On the back side of the face plate that is box-shaped by end-to-end welding processing after bending the end of the clad thin plate of corrosion-resistant metal such as titanium, aluminum or copper or these metals and other metal into the state in which the tip is rolled inward, A honeycomb for imparting the surface accuracy and durability of the face plate and a stat bolt for mechanically joining the filler to the filler are joined together, and fire resistance, sound insulation, heat insulation, strength and rigidity of ordinary mortar or carbon fiber reinforced mortar are provided. A cement-based filling material for a building is filled, and a building attachment jig is buried in the filling material. Further, the manufacturing method of the exterior metal panel in the present invention is such that the face plate in the metal panel having the above-mentioned configuration is received by a smooth formwork, and the uncured cast cement-based filler surface is covered with a vacuum mat to be dehydrated and deaerated. And then cured. Alternatively, the face plate is received by a smooth formwork having fine holes for ventilation, which is the top plate of the decompression chamber, and the casting cement-based filler is cured while decompressing.

In the exterior metal panel configured as described above, since the filling material is an irregularly shaped material, the box-shaped face plate can be densely filled and the end face of the face plate is placed inside. Since it is entangled, the effect of embracing the filler is enhanced and all of its thickness can contribute to the reinforcement, and the end of the face plate is buried in the filler layer or in the folded surrounding dense space where moisture does not adhere. Therefore, a durable integrated structure is provided without the risk of corrosion. In the case of arranging the reinforcing rod, the face plate can be thinned because the face plate is provided with strength and rigidity. In the case of multi-point backing with honeycomb, the surface accuracy of the face plate is improved. When the stat bolt is provided, the mechanical joining force between the face plate and the filler is increased, and the durability against repeated external force (wind, heat, etc.) is improved. In the method of coating the surface of the filler with a vacuum mat for dewatering and degassing, or using the decompression chamber as a mold,
Pressurized dehydration action works on the filling material, the strength of the filling concrete develops quickly, and early demolding becomes possible. Thus, the filled concrete has high strength and high density, and the drying shrinkage is also reduced. Furthermore, since the face plate is pressed against the mold under atmospheric pressure, the smoothness of the face plate can be easily obtained.

EXAMPLE An example will be described with reference to the drawings. In FIG. 1, a mode in which the end of a corrosion-resistant metal such as titanium, aluminum or copper or a clad thin plate of these metals and another metal is wound inside The face plate 10 that is bent into a box and is box-shaped by end-to-end welding (welding of the same material) has fire resistance, sound insulation, and heat insulating properties such as ordinary mortar and carbon fiber reinforced mortar in the void formed on the back side. A cement-based filler 11 for imparting strength and rigidity is filled, and a building mounting jig 12 is buried in a predetermined portion of the filler 11. Face plate 10
Since it is only subjected to end-bending reinforcement, the plate thickness must bear the required strength and rigidity, and it is difficult to reduce the thickness, but the amorphous filler 11 that is poured into the deep corners. Since it can wrap around and be filled, it can be securely held to form an integral structure, and the filling material 11 has a fire resistance due to its layer thickness.
Since it contributes to sound insulation, heat insulation, reinforcement, and stiffening, it can bring about a reduction in the thickness of 11 layers of the filler as a synthetic body. Since the building mounting jig 12 is buried in the filling material 11 as an independent body, the functions of other members are not restricted. Since the face plate 10 itself does not have a backing reinforcement measure, the cost is low.
In FIG. 2, the face plate 10 is reinforced and stiffened by backing a reinforcing coffin material 13 made of the same material such as a hollow frame. This reinforcement and stiffening may make the face plate 10 thinner. Also, the filler 11 can be thinned as shown in the figure because the burden of reinforcing and stiffening the above-mentioned reinforcing rod 13 is reduced. Since the bent portion 9 of the end portion of the face plate 10 comes into contact with the side surface of the reinforcing cauldron 13 as shown in the drawing and is hidden in the enclosed hermetically sealed space 14, there is no risk of corrosion. The building mounting jig 12 is a reinforcing material 1.
It is fastened and fixed to the connector 3 and does not restrict the functions of other members as in FIG. In FIG. 3, in addition to that of FIG. 2, the face plate 10 is provided with stat bolts 16, ... Made of the same material for mechanical joining of the filling material. As a result, the integration of the face plate 10 and the filler 11 is significantly guaranteed. In FIGS. 4 and 5, a honeycomb 17 for imparting surface accuracy and durability is joined to the face plate 10 by brazing or spot welding, and an amorphous filler 11 is placed on the honeycomb 17 for building installation. The jig 12 is buried in the filling material 11. As a result,
It is possible to secure the surface accuracy and make the face plate 10 thinner. In FIG. 6, stat bolts 16, ... Are added to those in FIGS. As a result, a guarantee of integration between the face plate 10 and the filling material 11 is added. FIG. 7 and FIG. 8 introduce a special construction example when filling the irregular-shaped filler 11 in the exterior metal panel of the present invention. That is, the surface accuracy of the face plate 10 is enhanced by utilizing the vacuum or pressure action, and the filler 1
It is intended to enhance the adhesion effect with 1. In FIG. 7, the face plate 10 is placed on the panel manufacturing table 18, and the filler 1
When 1 is cast, the upper part is covered with a vacuum mat 19, and dehydration and deaeration are performed via a drawing tube 20. Then, the filling material 11
Atmospheric pressure is strongly applied to the upper surface of the filling material 11 through the vacuum mat 19 by deaeration and vacuuming at the interface between the vacuum mat 19 and the vacuum mat 19. Thus, the pressure dehydration accelerates the strength development of the filler 11 and enables early demolding. Further, the filler 11 has high strength and high density, and the drying shrinkage is also reduced. Furthermore, since the atmospheric pressure presses the face plate 10 against the panel manufacturing table 18, the smoothness of the face plate 10 can be easily obtained. In FIG. 8, the same effect is achieved by another means. That is, after the filling material 11 is placed on the face plate 10 placed on the panel manufacturing table 18 'configured in the decompression chamber, the pressure is reduced through the drawing pipe 21 so that the atmospheric pressure acts.

Since the present invention is constructed as described above, it has the following effects. That is, since the contact between the face plate constituent metal and the other metal body is avoided, it is not necessary to worry about the corrosive relationship, which is preferable. Since the backing material is an irregularly shaped filling material and it is considered to be integrated with the face plate, the synthetic effect is great and the face plate and the like can be thinned. In the case of a thin plate, embossing, coloring, etc. can be easily performed, so that it is possible to add designability. Since it ensures surface accuracy, it is a good product. High durability can be expected. Since it can be processed in the factory, high quality is guaranteed, and since it is an integrated panel, it has the advantages of light weight and easy construction.
