Description

  The present invention relates to the manufacture of a ceiling decorative material that constitutes a roof ceiling structure, and can reduce the manufacturing cost, minimize the production of waste materials, and make a great contribution from the viewpoint of energy and resource saving. The present invention relates to a method for manufacturing a decorative material.

  Conventionally, wall materials such as various heat insulating materials are used for the ceiling of a building, and a structure in which a decorative material is disposed on the indoor side is generally employed. As this decorative material, a metal plate material such as various steel plates is used, and a plate material called punching metal in which numerous holes of various shapes having a diameter of several mm to several cm are used.

By forming holes in the ceiling decorative material, a large number of extracted pieces corresponding to the holes are generated, but the extracted pieces have a small diameter of about several millimeters to several centimeters as described above. There was no use for it, and it was a waste material. Many scraps that have become waste materials are heated and melted by industrial waste disposal contractors and recycled as various metal molded products. At that time, the cost and energy consumption for processing are reduced. Is inevitable. Therefore, especially in the current situation where the cost of raw materials for the ceiling and the entire building is high due to the recent rise in the price of metal plate materials, the formation of waste materials as described above is extremely undesirable.
Then, an object of this invention is to provide the manufacturing method of the ceiling decorative material which can eliminate the said trouble.

  The present invention has been proposed in view of the above, and is a method for manufacturing a metal ceiling decorative material in which a wall material is disposed on the upper side of a decorative surface to form a ceiling material, and the decorative surface has a plurality of rectangular shapes. The present invention relates to a method for manufacturing a ceiling decorative material, characterized in that a rectangular metal plate separated by the processing is used as an auxiliary material used in a roof structure.

The present invention also proposes a method for manufacturing a ceiling decorative material, characterized in that, in the method for manufacturing a ceiling decorative material, the auxiliary material used for the roof structure is a joint scraper or a holding member for an exterior material. .
When a rectangular metal plate separated from the decorative surface of the ceiling decorative material is used as a joint discard plate, of course, the rectangular metal plate material has a configuration (shape) as a joint discard plate as necessary. In other words, it can be rephrased as a method of manufacturing a ceiling decorative material and a joint scraper.
Similarly, when a rectangular metal plate separated from the decorative surface of the ceiling decorative material is used as the exterior material holding member, of course, the rectangular metal plate material is configured as the exterior material holding member as required ( In other words, it can be rephrased as a method for manufacturing a ceiling decorative material and a holding member for an exterior material.

The method for producing a ceiling decorative material according to the present invention is capable of producing a ceiling decorative material and at the same time producing a rectangular metal plate material used as an auxiliary material for a roof structure, and is a piece of punched metal in the related art. Since no generation occurs, no processing related to the production of waste materials is required, so that the manufacturing cost can be reduced.
In addition, since the production of waste materials can be minimized, there is no need for processing related to recycling in an industrial waste disposal contractor, which contributes to energy saving and resource saving.
Furthermore, since a new metal plate material has been conventionally processed and manufactured as a connecting member for the exterior material, the raw material cost can be eliminated.

  Moreover, when the subsidiary material used for a roof structure is a joint discard board, it can be used as a joint discard board by giving a simple process to the side edge etc. of the rectangular-shaped metal plate material produced with the said manufacturing method. Therefore, the processing cost can be greatly reduced.

  Furthermore, when the auxiliary material used for the roof structure is a holding member for an exterior material, it can be used as a holding member for an exterior material by appropriately bending the rectangular metal plate produced by the manufacturing method. Therefore, the processing cost can be greatly reduced.

  The method for manufacturing a ceiling decorative material according to the present invention is a process for forming a plurality of rectangular openings on a decorative surface, and a conventional punching metal has a diameter of several mm to several cm as described above. Are formed with openings having a length and width of more than a dozen cm.

  For this ceiling decorative material, for example, a long metal sheet formed to a predetermined thickness is supplied to a roll roll as a raw material for molding, and is cut at a predetermined length while being fed at a constant speed in the length direction. If necessary, process the side edge and the end in the length direction, but at that time, cut one side along the length of the original fabric and the other side perpendicular to the length direction. It is desirable to perform processing so that a plurality of rectangular openings are formed.

The ceiling decorative material is not particularly limited with respect to decoration such as the material, thickness, or color tone of the metal plate material. For example, various plated steel plates, stainless steel plates, surface decorative steel plates, laminated steel plates, aluminum alloys A known metal material such as a plate or a titanium alloy plate can be used.
And, for example, depending on the wall material combined on the upper side of the ceiling decorative material, or affected by the architectural style and the frame structure, for example, the strength is almost required even when a certain level of strength is required. There may be no. For example, various types of color tone are used depending on combinations and preferences with other various indoor building materials. In this way, the plate thickness, material, and color tone may be appropriately selected and used.

  The wall material that forms the ceiling material in combination with the ceiling decorative material is not particularly limited, but as described above, the wall is deformed in the openings having a length and width of more than a dozen centimeters, and protrudes or falls indoors. Any known wall material having such properties as heat insulation, negative ion generation function, sound absorption, sound insulation, fire resistance, etc. may be used. In addition, a wall material having a two-layer structure may be used. In that case, it is preferable to use a high-strength wall material for the lower layer. However, particularly when a low-strength wall material is used for the lower layer, the two are bonded in advance. And an integral wall material.

The plurality of rectangular metal plate materials are separated from the main body (ceiling decorative material) by the processing in which the plurality of rectangular openings are formed, and the metal plate materials are used as sub-materials used for the roof structure.
As a secondary material used in this roof structure, for example, a connecting member for an exterior material disposed inside the roof structure, more specifically, a joint discard plate used for connecting the end portions of the exterior material in the lateral exterior structure It may be used as a holding member for exterior materials used for connection of the left and right ends of the exterior materials in vertical walled exterior structures (attachment to the base), and each storage member such as a face door member, drainer, keraba wrap, etc. Alternatively, there are various reinforcing (for) members, various connecting (for) members, and the like.

  When a rectangular metal plate separated from the decorative part of the ceiling decorative material is used as a joint discard plate, as described above, materials having various plate thicknesses, materials, and colors are used as the ceiling decorative material as a raw material. However, the function of the joint discard plate is not affected by those conditions (plate thickness, material, color tone), and thus is applied without causing any trouble.

  When a rectangular metal plate separated from the decorative portion of the ceiling decorative material is used as the exterior material holding member, there are the following first and second modes as preferred modes.

  As a first aspect, a standing part provided with a holding part for holding a side edge molding part of the vertical facing exterior material, and a horizontal piece extending from the lower end of the standing part to at least one of the left and right sides and extending along the base The fixing part is a fixing part, and is fixed to the fixing part by hitting a fixing tool for restricting the movement of the vertical casing material arranged on one side at least when the negative pressure is applied. This exterior material holding member holds the left and right side edge molding portions of the longitudinally wound exterior material at the retaining part, and also regulates the movement of the longitudinally facing exterior material by the fixing device when negative pressure acts due to strong wind or the like. Therefore, it is possible to stably attach and hold the vertical covering material without detachment.

  As a second aspect, there are a standing part provided with a holding part that holds the side edge molding part of the vertical facing exterior material, and a horizontal piece part that extends from the lower end of the standing part to one of the left and right sides and runs along the base. It consists of a fixed part and a second horizontal piece part that extends to the other side and extends along the base. The second horizontal piece part is bent to the surface side and is locked to a vertical casing that is arranged on the other side. A locked portion is provided, and a fixing tool is struck to the fixing portion to fix it on the base. This exterior material holding member holds the left and right side edge molding portions of the longitudinally wound exterior material at the retaining portion, and regulates the movement of the longitudinally facing exterior material by the locked portion when a negative pressure is applied due to a strong wind or the like. As a result, the vertical covering material does not come off and can be stably attached and held. In addition, since the exterior material holding member retains the longitudinally wound exterior material at the retaining portion and the locked portion other than when the negative pressure is applied, the longitudinally sheathed exterior material is more reliably and stably attached and held. It will be a thing.

  That is, in the first aspect, a fixing tool is struck to the fixing part on one side, and the movement of the vertical covering material is regulated by the fixing tool. In the second aspect, the second horizontal piece on the other side is controlled. A locking part is provided in the part, and the movement of the vertical covering material is regulated by the locking part, and the first aspect and the second aspect may be combined. In that case, since both the fixing member and the locked portion regulate the movement of the other-side vertical casing when the negative pressure is applied, the mounting stability at the time of the negative pressure is extremely high.

  Further, in the exterior material holding member, it is desirable that the retaining portion has a corrugated shape, and a contact surface when retaining the side edge molding portion of the longitudinally facing exterior material is increased, so that the retaining portion can be retained more reliably. it can.
