Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention is a composite material composed of a metal outer skin and a core material with the outer skin arranged on the front and back. It is about the panel.

[0002]

[Prior art]

  A core material made of rigid polyurethane foam, etc. Composite panels with leather are often used as building materials with thermal insulation and sound insulation. However, a composite panel of this kind generally has a fruit on one end and a tenon on the other end due to the outer skin. The core material and the side edges of the outer skin are exposed on both end surfaces. this The core material exposed on the side end face is easily damaged even if the material is inorganic For this reason, a protective film, which is originally equivalent to the outer skin, is required. It has been devised to remove part of the side edges of the material and fold it to cover it. It

[0003]

[Problems to be solved by the device]

  However, the work efficiency and workability in the case of continuously producing and cutting composite panels In view of the above, the above-mentioned ones have various problems and have not been put into practical use.   The present invention has been made in view of these points, and the purpose is to An object of the present invention is to provide a composite panel in which a protective layer on the end face can be easily formed.

[0004]

[Means for Solving the Problems]

  The present invention, however, has an outer skin made of a metal material and a core material having the outer skin on the front and back sides. In the composite panel consisting of, the side where the core material is exposed and the side edges of the outer skin are exposed. It is characterized in that a protective layer formed by metal spraying is provided on the end face.   According to the present invention, the protective layer can be easily formed by metal spraying.

[0005]

【Example】   The present invention will be described in detail below with reference to the illustrated embodiment. In FIG. Organic foam such as polyurethane foam, or inorganic such as Ca-Si The core material 1 is composed of a plated steel plate, a coated steel plate, and stainless steel. It is covered with an outer skin 2 made of a metal material such as a plate or an aluminum plate. 2 forms a fruit 21 and a tenon 22 on the other end side. And this composite On the side end surface of the flannel P where the core material 1 and the side edge of the outer skin 2 are exposed, arc spraying is performed. The protective layer 3 is formed by low temperature metal spraying.

[0006]   The protective layer 3 is made of a metal such as Zn, Zn-Al, or Al and has a thickness of 50 to 100 μm. And is formed by, for example, the arc sprayer 4 shown in FIG. This arc The thermal spray machine 4 applies an arc induction voltage between the two thermal spray metal wires 40, 40, and An arc is generated between both metal wires 40, 40 at the tip of the lid 41, By sending high pressure air for atomizing to the head 41, the metal wires 40, 40 are melted. It is a means of ejecting a beam toward the surface to be sprayed. In the figure, 42 is the transmission of the metal wire 40 It is a roller portion for slip-in.

[0007]   When performing metal spraying, as shown in FIG. 2, a plurality of composite panels P are stacked. Grooves are overlapped, and grooves or protrusions that fit into the real 21 and the tenon 22 are provided on the side edges. The combined side panel 50, 50 and the upper and lower covers 51, 52 covering the upper and lower surfaces are combined panels. Surrounding the side end surface of P, in this state, metal spraying is performed by the spraying machine 4. metal The protective layer 3 obtained by thermal spraying covers the side end surface of the core material 1 and the side edge of the outer cover 2.

The thickness of the protective layer 3 can be set to the above value by changing the moving speed of the head 41 of the thermal spraying machine 4 or the feeding speed of the metal wire 40. Now, the metal wire 40 is 1.1 mm in diameter, the feeding speed is 10 m / min, the applied voltage is about 150 A × 16 V, and the air pressure of the high-pressure air is 7.5 kg / cm ² , and the metal spraying is performed using the thermal spraying machine 4. If the moving speed of the head 41 is 3 m to 6 m / min, the protective layer 3 having a thickness of 50 μm to 100 μm can be obtained. The distance between the head 41 and the surface to be sprayed is preferably 30 to 50 cm. When it is desired to further increase the thickness of the protective layer 3, metal spraying may be performed multiple times. Further, in this metal spraying, powder of ceramic such as Al ₂ O ₃ , SiO ₂ , SiN ₂ may be mixed in the spraying flow. The metal forming the protective layer 3 is disadvantageous in terms of cost, but Cu, SUS or the like may be used.

[0009]   The composite panel P on which the protective layer 3 is formed by performing the metal spraying as described above has a side end surface. Not only is protected by the protective layer 3, but also as shown in FIG. The side surfaces of the flannel P are abutted against each other, and a silicon resin is provided between the facing surfaces. When the fat-based caulking agent 6 is placed, the core material 1 is a silicone resin called silicone. Even if it does not adhere well to the resin and does not adhere to it, the metal protective layer 3 Good adhesion to the caulking agent 6 because it contacts the caulking agent 6 The state is obtained.

[0010]

[Effect of device]

  As described above, in the present invention, the core material is exposed and the side edges of the outer skin are exposed. It has a protective layer formed by metal spraying on the end surface on the side where The protective layer can be easily formed, and at this time, the shape of the side end face restricts the formation of the protective layer. And the protective layer formed in this way is Since it is familiar, it is possible to obtain a good construction condition.
