  However, since this door uses an inner plate material as a single plate, warpage tends to occur. In addition, since at least three plate members including the outer plate member are required, the overall weight is increased, and it takes time and labor during transportation and construction.

  Therefore, the problem to be solved by the present invention is to provide a door having a novel configuration that prevents the occurrence of warping and realizes a light weight while giving the same design as the above-described conventional technology.

In order to solve this problem, the present invention according to claim 1 includes: a core assembly material in which a core material is assembled in a rectangular shape; and two surface materials adhered to the front and back of the core assembly material. In the door, at least one surface material is formed with one or more through holes, and an inner surface material having a larger plane dimension than the through holes at a position corresponding to the through holes of the surface material inside the core assembly. Is fitted and fixed between the core members in a state where the pair of end surfaces are in contact with the side surfaces of the core member, and the inner surface member is exposed from the outside of the door through the through hole.

  According to a second aspect of the present invention, in the door according to the first aspect, a core assembly including the inner surface material, wherein the inner surface material is fitted into the core assembly material so as to be substantially flush with the surface of the core assembly material. It is fixed by an adhesive at the contact surface between the surface of the material and the back surface of the surface material.

  According to a third aspect of the present invention, in the door according to the first or second aspect, at least a portion of the surface of the inner surface material exposed from the through hole of the surface material has releasability, and is applied onto the surface portion. The cured adhesive can be peeled and removed through a through hole after curing.

The present invention according to claim 4 is a core assembly in which the core material is cored in a rectangular shape, and the inner surface material is fitted and fixed between the core materials in a state where the pair of end faces are in contact with the side surfaces of the core material. Prepare two surface materials with one or more through holes formed in at least one plane dimension smaller than the inner surface material, and apply adhesive to the front and back of the core assembly including the inner surface material. The surface material is attached to the front and back of the core material through the adhesive so that the positions of the inner surface material inside the material and the surface material correspond to each other, and after the adhesive is dried and cured, The dry and cured adhesive is peeled and removed through the through hole.

  Since the door of the present invention uses a core material obtained by assembling the core material and has surface materials attached to the front and back, it can be manufactured at a low cost and at the same time, warpage is unlikely to occur. .

  Also, the inner surface material is fitted inside the core material so that it is substantially flush with the surface of the core material, so that the contact surface between the surface of the core material including the inner material and the back surface of the surface material is bonded. It can be firmly fixed by the agent to improve the strength of the door. In addition, since no gap is generated between the inner surface material and the surface material, intrusion of moisture and the like is prevented, and the effect of preventing warpage is great.

  Further, at least a portion of the surface of the inner surface material exposed from the through hole of the surface material has releasability, so that the adhesive applied on the exposed surface portion is peeled off through the through hole after curing. Since it can remove, it can manufacture easily, without processing a surface material and a core assembly.

It is a front view which shows the core material of the door by the Example 9 of this invention (inner surface material is inserted and fixed inside).

  First, the components of the door of the present invention will be described.

  The core material constituting the door of the present invention is a core material in a rectangular shape, for example, a length of 50 to 2400 mm, a width of 2 to 40 mm, and a thickness of 20 to 30 mm (corresponding to the door thickness). These core materials are arbitrarily assembled using staples, tuckers, nails or the like to obtain a core assembly material having a height of 1600 to 2400 mm, a width of 500 to 900 mm, and a thickness of 20 to 30 mm. Wood materials such as MDF, LVL, plywood, and solid wood are used for the core material. Considering that the core assembly has a required strength, a honeycomb material or the like may be inserted between the core assemblies of the core assembly material (except for a portion where the inner surface material is inserted).

  The inner surface material inserted into the core frame material is a plate material having a thickness equal to or thinner than that of the core frame material. For example, the length is 100 to 2350 mm, the width is 10 to 830 mm, and the thickness is about 2 to 30 mm. is there. The inner surface material is fixed to the core material that comes into contact with the inner surface material by using staples, tackers, nails, an adhesive, a double-sided tape, and the like. If the inner surface material is the same thickness as the core material, the surface of the core material, including the inner surface material that is inserted, will be flush with the inner surface material. This is preferable because it can be fixed.

  The material of the inner surface material is not particularly limited, but wood materials such as MDF, LVL, and plywood, synthetic resin materials such as plastic, translucent materials such as glass and acrylic plates, and metal materials such as aluminum can be used. . As will be described later, the inner surface material preferably has a surface property (releasability) that can be peeled after drying even if an adhesive is once applied to the surface, and when using the inner material of a wood material, Attaching a decorative sheet (for example, a sheet coated with a silicon-based coating film or an aluminum sheet) having a releasability to the surface or coating a synthetic resin paint such as a silicon-based releasability It is preferable to keep it. When using an inner material such as a synthetic resin material, a light transmissive material, a metal material, etc., it can be used as it is because the material itself has releasability. Needless to say, the releasability may be improved by painting or the like.

  The inner surface material may be incorporated when the core material is cored and formed integrally with the core material, or after forming the core material, it is processed into a shape that fits between the core materials and fitted into the core material. Also good. In addition, when inserting an inner surface material having a dimension larger than the length and / or width between core materials, the entire core material at a position that interferes with the insertion of the inner surface material or the thickness of the inner surface material Only cut out and insert the inner material (FIGS. 7 and 11).

  As described above, it is preferable that the inner surface material is flush with the surface of the core assembly material in a state where the inner surface material is fitted inside the core assembly material. It is only necessary to fit inside the assembly (FIGS. 3, 4 and 9). However, when using an inner material thinner than the core assembly, a honeycomb material formed from corrugated paper or a synthetic resin foam material is used. The inner surface material is supported by a base material such as a woody material such as MDF, LVL, and plywood, or a synthetic resin material such as plastic, and the total thickness thereof is the same as the thickness of the core material. It is preferable that the surfaces formed by These base materials may be formed in the same planar shape as the inner surface material, and may be fixed to one or both surfaces of the inner surface material (FIGS. 5 and 6), and cut into arbitrary pieces to form a piece shape May be provided at regular intervals between the inner surface materials. The base material that supports the inner surface material is attached to the inner surface material and the core material to be contacted with an adhesive or a double-sided tape.

  When using an inner surface material made of a translucent plate such as glass or acrylic, it is preferable to use the inner material so as to be bridged over a base material formed in a piece shape. At this time, it is preferable that the base material is disposed so as not to be seen from the through hole of the surface material (FIGS. 13 and 14). Moreover, you may apply | coat a base material, or may affix a decorative sheet and an aluminum sheet so that it may not look bad when looking through a through-hole from the door surface.

  When the inner surface material is thinner than the core material and has a size larger than the length and / or width between the core materials, the surface portion of the core material at a position that interferes with insertion of the inner surface material It is preferable to cut away the portion of the inner surface material by the thickness of the inner surface material so that the surface formed by the inner surface material and the core member is flush with the surface material (FIG. 7). It is better to interpose a base material that supports the inner surface material between at least two core materials to which the inner surface material is stuck (FIG. 7), but when using an inner surface material made of a light-transmitting plate such as glass or acrylic As described above, it is preferable to dispose it across the piece-like base material, or to insert it into the excised portion of the core material surface without using the base material. Also, the core of the core material may be painted, or a decorative sheet or an aluminum sheet may be attached so that it does not look bad when looking through the through hole from the door surface.

  The surface material adhered to the front and back of the core assembly is formed to have a height of 1600 to 2400 mm similar to the door, and has a width of 500 to 900 mm and a thickness of about 2 to 3 mm. The surface material is a wood material such as MDF, plywood, or solid material, and the surface is subjected to surface treatment such as a decorative sheet, an aluminum sheet, or painting. As the decorative sheet, it is preferable to use a decorative sheet having moisture-proof paper pasted on both sides.

At least one surface material is formed with a through-hole having a size smaller than that of the inner surface material at a position corresponding to the inner surface material fitted into the core member. The through-holes may be formed in an arbitrary shape, and a plurality of through-holes may be formed as long as they correspond to the location of the inner surface material inside the core assembly.
Apply the moisture-proof paint to the end face (opening edge) of the through-hole formed in the surface material, wrap the decorative sheet attached to the surface material, attach the end decorative material, It may be inserted. Furthermore, the moisture-proof effect can be further enhanced by applying a moisture-proof paint to the periphery of the back surface side through-hole of the surface material.

  Moisture-proof paint applied to the perforated side and back side of through-holes includes acrylics such as phthalic resin and acrylic resin, urethanes such as acrylic urethane resin, polyurethane resin, and epoxy resin, and acrylic silicon resin. Fluorine-based moisture-proof paints such as silicon and fluorine resins are suitable.

  Next, the manufacturing method of the door of this invention is demonstrated generally. First, a core assembly in which an inner surface material is fitted and fixed inside is obtained. That is, the core materials processed into an arbitrary length are fixed using staples, tuckers, nails or the like to form a rectangular frame to obtain a core assembly material. In this core assembly, the inner surface material may be incorporated into the core assembly material, or may be inserted between the core materials after obtaining the core assembly material. The inner surface material is fixed to the core material using staples, tucker, nails or the like. Depending on the type (material) of the inner surface material, an adhesive may be applied to the contact surface with the core material, or a double-sided tape may be adhered and fixed.

  For the surface material, at least one of the front and back surface materials is provided with a through hole having a size smaller than that of the inner surface material at a position corresponding to the inner surface material inserted into the core material when the core material is attached. Form. The through hole can be formed by press processing, laser processing, NC router processing, or the like. In the processed mouth (opening edge of the through-hole), a decorative sheet to be attached to the surface material can be wound, a mouth-to-mouth decorative material can be attached, or a molded product can be fitted into the makeup.

  An adhesive is applied to the front and back surfaces of the core assembly and / or the back surface of the surface material by a roll coater or a spreader. In the case where an adhesive is applied only to the front and back surfaces of the core material, or both the front and back surfaces of the core material and the back surface of the surface material, a vinyl acetate adhesive is suitable.

  However, when applying an adhesive on the back side of the surface material, a large amount of adhesive is required because the adhesive will be applied in addition to the bonded part with the core material to be attached, The moisture released from the adhesive due to the application of the adhesive may cause the door to warp. Therefore, it is preferable to apply the adhesive to the core material side.

  The surface material is placed on the front and back surfaces of the core material so that the through hole of the surface material matches the inner surface material arranged on the core material, and is bonded and integrated by pressing.

  Thereafter, after the adhesive is dried, the adhesive dried and solidified on the surface of the inner surface viewed through the surface material through hole is peeled off and removed. Since the surface of the inner surface material has releasability, the dried and cured adhesive can be easily peeled and removed. The door of this invention is manufactured by the above.
