The flat plate shape is a shape having two main surfaces having a large area with respect to the thickness.

Since the core material 12 is a member used as the core of the door structure 10, it is preferable that the core material 12 has rigidity. The material of the core material 12 may be made of wood, resin, or a composite thereof. The material can be appropriately selected according to the characteristics required for the door structure 10.

In the case of the wooden core material 12, for example, as the material, a material such as a wood fiber board such as a medium density fiberboard (MDF (Medium Density Fiberboard)), a plywood, or a particle board can be appropriately used as the core material 12. Medium density fiberboard is specified in JIS A5905. Plywood is composed of laminating a plurality of veneers. Particleboard is manufactured by heating and compressing small pieces of wood with an adhesive and is specified in JIS A5908.

In the case of the wooden core material 12, for example, a so-called solid structure (solid core structure) such as a wood fiber board, plywood, or particle board, and a flash structure board can be applied as the structure. The flash structure board is a hollow structure in which a frame is made of wood and plywood is attached to both sides. The density can be reduced compared to a solid structure.

The density of the wooden core material 12 ^{is preferably 400 kg / m 3} or more and 900 kg / m ³ or less. When the density of the core material 12 is 400 kg / m ³ or more, the strength of the core material 12 can be ensured. When the density of the core material 12 is 900 kg / m ³ or less, the weight of the door structure 10 can be reduced. The density of the wooden core material 12 is more preferably ^{500 kg / m 3} or more and 800 kg / m ^{3 or less.}

The plate thickness of the wooden core material 12 can be appropriately selected according to the thickness of the door structure 10.

The specific gravity of the core material 12 is preferably 0.4 or more and 0.9 or less, and more preferably 0.5 or more and 0.8 or less.

<Plate-shaped body>
As the plate-shaped body 16, if it is a brittle material, the effect of the present invention can be enjoyed. Brittle means the property of being easily broken when subjected to force. For example, examples of the material of the plate-shaped body 16 include a glass plate, a resin plate, and a ceramic plate. The resin plate is preferably a brittle resin plate. Examples of the brittle resin plate include a melamine-based resin plate, an acrylic-based resin plate, a polycarbonate-based resin plate, a vinyl chloride plate, and the like. Examples of the ceramic plate include ceramic members such as tiles. The plate-like body may be made of stone. Hereinafter, a case where the plate-shaped body 16 is a glass plate will be described.

The type of glass of the glass plate applied to the plate-shaped body 16 is not particularly limited. For example, soda lime glass, non-alkali glass, aluminosilicate glass and the like can be mentioned. When chemically strengthening the glass, aluminosilicate glass containing 3% or more _{of Al 2} O ₃ in mass% based on the oxide is preferable.

The thickness of the glass plate is preferably 0.5 mm or more and 6 mm or less. When the thickness of the glass plate is 0.5 mm or more, the warp of the core material 12 can be absorbed. If the glass plate is 6 mm or less, the entire door structure 10 does not become heavy, and transportation and construction become easy. The thickness of the glass plate is more preferably 1 mm or more, further preferably 1.5 mm or more. The thickness of the glass plate is more preferably 4 mm or less, further preferably 3 mm or less.

If the plate-like member 16 is a glass plate, the density of the glass plate is preferably at most 2300 kg / ^{m 3} or more ^{2800kg / m 3, 2400kg / m} 3 or more 2600kg / ^{m 3} or less is more preferable. The specific gravity of the plate-shaped body 16 is preferably 2.3 or more and 2.8 or less, and preferably 2.4 or more and 2.6 or less.

The glass plate applied to the plate-shaped body 16 is preferably in close contact with the design layer 18. When the design layer 18 is viewed through the plate-like body 16 by being in close contact with the door structure 10, the door structure 10 has an increased sense of depth and luxury and is aesthetically superior. Further, the visible light transmittance (obtained in accordance with JIS R3106) based on the standard A light source of the glass plate is aesthetically preferable, 45% or more is more preferable, and 60% or more is further preferable. , 70% or more is particularly preferable. The upper limit of the visible light transmittance based on the standard A light source of the glass plate is not particularly limited, but may be 100% or less, 92% or less, or 90% or less.

In addition, in order to provide a texture on the surface of the glass plate, the surface may be textured by post-processing such as frosting.

The glass plate can be produced by a known method. That is, a glass plate is manufactured by cutting glass formed into a ribbon shape by a float method, a fusion method, a down draw method, a rollout method, or the like.

The glass plate may have a compressive stress layer on the surface layer. When the glass plate is tempered, the glass plate becomes a tempered glass plate. The tempered glass plate that has been subjected to the tempering treatment is less likely to break than the case where the tempered glass plate has not been subjected to the strengthening treatment. The tempered glass plate includes a compressive stress layer on the surface layer, that is, a front surface layer and a back surface layer having a residual compressive stress, and an intermediate layer formed between the front surface layer and the back surface layer and having a residual tensile stress. The residual compressive stress decreases from both ends in the thickness direction of the tempered glass plate toward the inside, and a residual tensile stress is generated inside the tempered glass plate.

The end face of the tempered glass plate may be continuously covered with the residual compressive stress on the front surface layer and the back surface layer. Since the end face of the tempered glass plate is covered with the residual compressive stress, it is less likely to crack due to impact, which is preferable. The end face of the tempered glass plate is not covered with the residual compressive stress, and the end face of the intermediate layer may be exposed on the end face of the tempered glass plate. In that case, it is preferable that the cover material is covered with a resin or the like.

The tempered glass plate is produced by subjecting a tempering treatment to generate residual compressive stress on the front surface and the back surface of the glass plate. The tempered glass plate may be either a chemically strengthened glass obtained by a chemically strengthened treatment such as an ion exchange method or a physically strengthened glass obtained by a physically strengthened treatment such as an air-cooled strengthening method. With the chemical strengthening treatment, the value of the residual compressive stress of the front surface layer and the back surface layer can be increased even if the glass plate is thinner. For example, the value of the residual compressive stress of the surface layer is preferably 300 MPa or more, more preferably 400 MPa or more. The upper limit of the residual compressive stress of the surface layer is not particularly limited, but may be 1200 MPa or less, 800 MPa or less, or 600 MPa or less. In the case of chemically strengthened glass, the thickness of the compressive stress layer may be 50 μm or less, or 40 μm or less. Further, the thickness of the compressive stress layer may be 10 μm or more, or 20 μm or more.

In the ion exchange method, the front surface and the back surface of the glass plate are ion-exchanged, and ions having a small ionic radius (for example, Li ion and Na ion) contained in the glass are replaced with ions having a large ionic radius (for example, K ion). As a result, residual compressive stress can be generated on the front surface and the back surface of the glass plate. In the ion exchange method, a glass plate is immersed in a high-temperature treatment liquid to perform ion exchange.

The wind-cooling strengthening method quenches the glass plate at a temperature near the softening point from both sides and creates a temperature difference between the front and back surfaces of the glass plate and the inside of the glass plate to make the front and back surfaces of the glass plate. Residual compressive stress can be generated. Physical strengthening methods such as the wind-cooling strengthening method are much more productive than chemical strengthening methods such as the ion exchange method because the time required for the strengthening process is several seconds to several tens of seconds.

The plate-shaped body 16 may have a functional layer for adding a special function on the surface opposite to the adhesive layer 14. Examples of the functional layer include an antifouling film, an antibacterial film or an antifogging film.

The antifouling film has the effect of reducing the adhesion of fingerprints and making it difficult for stains to adhere. In particular, when the door structure 10 is directly touched by hand, fingerprints adhere to the surface of the plate-shaped body 16 and impair the design. Therefore, it is preferable to have an AFP (Anti-Finger Print) function for reducing the adhesion of fingerprints. The AFP function attaches the AFP agent to the plate 16 to form an AFP film on the glass plate. Examples of the AFP agent include fluorine-containing organosilicon compounds. The fluorine-containing organosilicon compound is not particularly limited as long as it imparts antifouling property, water repellency and oil repellency. The molecular weight of the AFP agent is preferably 3,000 or more and 10,000 or less, more preferably 3,000 or more and 8,000 or less, and further preferably 3,000 or more and 6,000 or less. When the molecular weight of the AFP agent is 3,000 or more, flexibility is imparted to the molecular structure, and scratch resistance and surface slip resistance can be obtained. Further, when it is 10,000 or less, a sufficient reactive group per molecule of the AFP agent can be secured, and the adhesion to the surface of the plate-shaped body 16 can be ensured.

The antibacterial film is formed by adhering an antibacterial agent exhibiting antibacterial properties to the plate-shaped body 16. Examples of the antibacterial agent include natural antibacterial agents such as wasabi, metal-based antibacterial agents such as copper and silver, and oxide-based antibacterial agents such as titanium oxide. In particular, a solution containing silver is applied to the plate-shaped body 16 to form a silver film, and the plate-shaped body on which the silver film is formed is heat-treated to diffuse silver ions from the surface of the plate-shaped body 16 to the inside. It is preferable to let it last from the viewpoint of sustainability of the effect.

The antifogging film is provided with a water-absorbent resin layer on the surface of the plate-shaped body 16, and the surface of the plate-shaped body 16 is fogged by absorbing and removing minute water droplets formed on the plate surface of the plate-shaped body 16. Has the effect of preventing and maintaining the design. The antifogging film includes, for example, an underlying layer and a water absorbing layer. The base layer is a layer for making it difficult for the water-absorbing layer to be peeled off from the glass plate, and is obtained, for example, by applying a composition containing a silane-based coupling agent to the plate-like body 16 and reacting it. The water-absorbent layer is obtained by applying a composition containing a raw material component of a cured resin selected from a cured epoxy resin, a urethane resin and a crosslinked acrylic resin onto the base layer and reacting the layers.

The Young's modulus of the plate-shaped body 16 is preferably 5 GPa or more. If the Young's modulus of the plate-shaped body 16 is 5 GPa or more, it is difficult to warp. The Young's modulus of the plate-shaped body 16 is more preferably 10 GPa or more, further preferably 30 GPa or more, and particularly preferably 50 GPa or more. The upper limit of Young's modulus of the plate-shaped body 16 is not particularly limited, but may be 100 GPa or less.

<Design layer>
A design layer 18 is formed between the plate-shaped body 16 and the adhesive layer 14. The design layer 18 is formed by, for example, applying a paint containing a coloring pigment to the surface of a glass plate, which is a plate-like body 16, and drying and curing the paint. Examples of the paint include acrylic resin-based paints. Acrylic resin-based paints have high adhesive strength and are also excellent in weather resistance and corrosion resistance. Moreover, it is preferable in that the finish is beautiful. The design layer 18 is not particularly limited as long as it can impart design properties, and may be, for example, a melamine resin-based paint or an epoxy resin-based paint, and the coloring pigment may be of various colors. Further, the design layer 18 may be a mirror coated with a metal film (Ag).

The coating method is not particularly limited, and for example, a roll coating method, a spray coating method, a dip coating method, a flow coating method, a screen printing method, a spin coating method, or the like is used.

Further, the design layer 18 formed into a sheet shape may be attached to the glass plate which is the plate-shaped body 16 by an adhesive or the like instead of the paint. In that case, the design layer 18 formed into a sheet shape may have a single color or a plurality of colors, or may have a pattern such as a natural stone tone or a brick tone. Further, the design layer 18 may be provided with a pattern on the surface of the plate-shaped body 16 with irregularities or the like, for example, the design may be imparted by a template glass.

<Adhesive layer>
The adhesive layer 14 is a member that connects the facing surfaces of the core material 12 and the plate-shaped body 16 to each other, and is selected from the group consisting of double-sided tape, silicone-based sealing adhesive, urethane-based adhesive, and resin with adhesive. it can.

Double-sided tape is generally a member having adhesive layers on both sides of a thin strip-shaped base material. As the base material, for example, a resin film, paper or the like can be used. Polyethylene, urethane, etc. can be used as the adhesive layer.

In addition, double-sided tape without a base material can be used. A double-sided tape without a base material is a member having no base material and having only an adhesive layer provided on the double-sided release paper. As the adhesive layer, an acrylic adhesive layer, a synthetic rubber adhesive layer, and a silicone adhesive layer can be used.

As a silicone-based sealing adhesive and a urethane-based adhesive, a general building sealing material can be used.

The resin with an adhesive is a member provided with adhesive layers on both sides of the functional resin (sides facing each of the core material 12 and the plate-shaped body 16).

As the resin, a resin that is a foam containing a skeletal resin that defines bubbles (cells) can be used. When a resin as a foam is produced by a chemical cross-linking method, a cross-linking agent is added to the skeleton resin to cause a cross-linking reaction by the cross-linking agent and a decomposition reaction of the foaming agent to retain gas components, thereby causing bubbles (cells). ) Is defined, and a resin having a predetermined foaming property is obtained.

The type of skeletal resin and the manufacturing method are not limited as long as the predetermined foaming characteristics can be obtained. As the skeleton resin, synthetic resin, synthetic rubber and the like can be used, and for example, polyethylene, silicone, polyurethane, ethylene-vinyl acetate copolymer (EVA), ethylene-propylene-diene rubber (EPDM) and the like can be used. ..

The bubbles defined by the skeleton resin are preferably closed cells. The closed cell body means a structure in which bubbles are arranged independently. By using a closed cell, the physical strength of the resin can be improved as compared with an open cell.

The skeletal resin constituting the resin preferably contains a flame retardant. The flame retardant suppresses the ignition of the resin.

The adhesive layer 14 may contain other components. As other components, for example, pigments, inorganic additives and the like can be contained. Various functions can be imparted to the adhesive layer 14. The presence or absence of a flame retardant or the like in the adhesive layer 14 can be measured by, for example, IR (infrared spectroscopy), TGA (thermogravimetric analysis), DSC (differential scanning calorimetry) or the like.

The adhesive on the side of the plate-shaped body 16 may be applied to the entire surface of the resin, or may be a part of the adhesive. It is advantageous to apply the adhesive to the entire surface because the plate-shaped body 16 is less likely to crack. As the pressure-sensitive adhesive, a general building sealant can be used, and examples thereof include a modified silicone-based sealant, an acrylic-based pressure-sensitive adhesive, and a synthetic rubber-based pressure-sensitive adhesive. The pressure-sensitive adhesive may be in the form of a sheet. Further, as the adhesive, it is suitable as a building material to select the material and the coating amount so as to have high nonflammability.

As the pressure-sensitive adhesive on the side of the core material 12, an acrylic pressure-sensitive adhesive type, a synthetic rubber type, a silicone type, or a modified silicone type can be used.

The adhesive on the side of the plate 16 and the adhesive on the side of the core 12 may be the same or different.

The adhesive layer 14 may be a liquid member or a plate-shaped member. When the adhesive layer 14 is a plate-shaped member, it may be integrally molded with the plate-shaped body 16 by injection molding or extrusion molding.

The thickness of the adhesive layer 14 is preferably 1 mm or more and 10 mm or less. When the thickness of the adhesive layer 14 is 1 mm or more, sufficient impact resistance can be obtained when laminated with the plate-shaped body 16.

When C = 100%, the adhesive layer 14 is provided on the entire surface of the first surface 12A of the core material 12. When C <100%, the adhesive layer 14 is provided on a part of the first surface 12A of the core material 12. When the ratio C is 10% or more, the core material 12 and the plate-shaped body 16 can be bonded.

The laminated body 17 is preferably composed of the core material 12, the adhesive layer 14, and the plate-shaped body 16 having a design property described above. However, the configuration is not limited to the above.

As shown in FIG. 5, the core material 12, the adhesive layer 14, and the plate-shaped body 16 are prepared. The adhesive layer 14 and the plate-shaped body 16 have substantially the same area. Therefore, the end face of the adhesive layer 14 and the end face of the plate-like body 16 are flush with each other. Here, the area is the area of the main surface of the adhesive layer 14 and the main surface of the plate-shaped body 16.

On the other hand, the area of the core material 12 is larger than the area of the adhesive layer 14 and the plate-shaped body 16. Therefore, the core material 12 protrudes from the adhesive layer 14 and the plate-shaped body 16. The end faces 17A of the laminated body 17 are not formed flush with each other.

Next, as shown in FIG. 6, the cutting blade 70 cuts the core material 12 and a part of the adhesive layer 14 along the end surface of the plate-shaped body 16. The cutting blade 70 completely cuts the core material 12. On the other hand, the cutting blade 70 cuts a part of the adhesive layer 14 and leaves the adhesive layer 14 at a distance L from the side of the plate-shaped body 16. Therefore, since the cutting blade 70 does not come into contact with the plate-shaped body 16, the plate-shaped body 16 can be protected from damage caused by the cutting blade 70.

Next, as shown in FIG. 7, the protruding portion of the cut core material 12 is removed, and the end surface 17A of the laminated body 17 becomes flush with each other.

Next, as shown in FIG. 8, the end face adhesive 62 is applied to the end face 17A of the laminated body 17, and then the molding material 60 is bonded to the end face 17A by the end face adhesive 62. The molding material 60 is attached to the end surface 17A of the laminated body 17 by, for example, an edge pasting machine (edge bander), and the door structure 10 shown in FIG. 1 is manufactured.

The edging machine (not shown) includes, for example, a transport unit that conveys the laminate 17, a coating unit that applies the end face adhesive 62 to the end face 17A, and a pressing unit that attaches the molding material 60 toward the end face adhesive 62. Etc. are provided. While the laminate 17 is being conveyed to the transport unit, the end face adhesive 62 is applied to the end face 17A by the coating unit, and then the molding material 60 is attached to the end face 17A by the pressing unit. In this way, the molding material 60 is attached to one end surface 17A of the laminated body 17. The molding material 60 is similarly attached to the remaining three end faces 17A, and the door structure 10 is manufactured.

In the laminated body 17 of the embodiment, the end faces 17A are flush with each other by the cutting blade 70. Therefore, the molding material 60 can be attached using the edge pasting machine.

As shown in FIG. 9, in the laminated body 17 constituting the door structure 11, a space S is formed on the side of the end surface 17A. The cutting blade 70 cuts the core material 12 along the end face of the plate-shaped body 16. The cutting blade 70 completely cuts the core material 12. On the other hand, since the core material 12 and the plate-shaped body 16 are arranged at a certain distance by the adhesive layer 14, a distance L1 can be provided between the cutting blade 70 and the plate-shaped body 16. Since the cutting blade 70 does not come into contact with the plate-shaped body 16, the plate-shaped body 16 can be protected from damage caused by the cutting blade 70.

In the laminated body 17 shown in FIG. 9, the end faces of the core material 12 and the plate-shaped body 16 are flush with each other by the cutting blade 70. Since the core material 12 and the plate-shaped body 16 having high rigidity are flush with each other, the molding material 60 can be attached using an edge pasting machine.

<Example>
The present invention will be specifically described with reference to the following examples of the door structure, but the fittings of the present invention are not limited to these examples.

For the door structure of the first embodiment, the following experiment was conducted to confirm the improvement of the adhesive strength between the plate-shaped body and the molding material.

(Tensile test)
FIG. 10 is a diagram of a tensile test for measuring the strength of the end face adhesive with respect to the molding material of the glass plate and the core material. As shown in FIG. 10, the molding material 100 and the member 102 are joined by an end face adhesive 104, and the member 102 and the molding material 100 are fixed to an autograph tensile tester, respectively, and pulled at a tensile speed of 5 mm / min. The test was carried out. A glass plate or plywood was used as the member 102, and a hot melt adhesive (W-1515S manufactured by Daikyo Co., Ltd .: EVA resin) was used as the end face adhesive. The adhesive area was 10 mm × 10 mm.

The adhesive strengths of the three glass plates and the three plywoods were measured in the initial state and after the thermal cycle.

As the cooling and heating cycle, the following (1) to (4) were set as one cycle, and nine cycles were carried out.
(1) -20 (± 2) ° C .: Adjusted at 2 hr.
In the preparation, the temperature was changed with a gradient such that the temperature in the constant temperature bath became −20 ° C. over 2 hours.
(2) -20 (± 2) ° C .: Holds 2 hr.
(3) 60 (± 2) ° C.: Adjusted at 2 hr.
(4) 60 (± 2) ° C.: Holds 2 hr.

After 9 cycles, the cells were stored at 23 ° C. and 65% RH for 24 hours.

Table 1 shows the tensile test results of the glass plate, and Table 2 shows the tensile test results of the plywood. The average value of the tensile strength of the glass plate is initially a 617.1 (N / cm ^2), the following thermal cycle was 203.7 (N / cm ^2). The average tensile strength of plywood was initially 412.9 (N / cm ² ) and 441.5 (N / cm ² ) after the thermal cycle.

(Tensile strength of door structure)
The tensile strength of a plurality of door structures was calculated by using the average value of the tensile strength of the glass plate and the plywood after the cooling and heating cycle. FIG. 11 is a table showing the door structure and the results of calculating the tensile strength. As shown in FIG. 11, in Examples 1 to 12, the total thickness was 18 mm, the thickness of the adhesive layer was 3 mm, and the thicknesses of the plate-like body and the core material were variously changed. In Example 13, the total thickness was 50 mm, and in Example 14, the total thickness was 9 mm, and the tensile strength was calculated. The tensile strength was calculated based on the following formula.
F (tensile strength) = A (%) x fg + B (%) x fs
(However, fg is the average strength of the plate-like body (glass plate) after the cold cycle, and fs is the average strength of the core material (plywood) after the cold cycle).
In FIG. 11, the adhesive strength of only the plate-shaped body is A = 100%, that is, the case where the core material is not provided. The magnification is the ratio of the adhesive strength of the door structure to the adhesive strength of only the plate-shaped body (adhesive strength of the door structure / adhesive strength of only the plate-shaped body).

According to the results of Examples 1 to 12 in the table of FIG. 11, the thickness ratio A to the total thickness of the plate-like body is preferably 25% or less, which is a magnification of the adhesive strength of 1.5 or more, and the magnification of the adhesive strength. Is more preferably 17% or less, which is 1.6 or more, and further preferably 9% or less, which is a ratio of adhesive strength of 1.7 or more.

According to the results of Examples 1 to 12 in the table of FIG. 11, the thickness ratio B in the total thickness of the core material is preferably 58% or more, which is a magnification of the adhesive strength of 1.5 or more, and a magnification of the adhesive strength. Is more preferably 66% or more, which is 1.6 or more, and further preferably 75% or more, which is a ratio of adhesive strength of 1.7 or more.

According to Example 13 in the table of FIG. 11, the total thickness is 50 mm, the thickness ratio A to the total thickness of the plate-like body is 1%, and the thickness ratio B to the total thickness of the core material is 97%. The strength ratio can be set to 2 or more. Further, according to Example 14, the total thickness is 9 mm, the thickness ratio A to the total thickness of the plate-like body is 66.7%, and the thickness ratio B to the total thickness of the core material is 22.2%. The ratio of adhesive strength can be 1.15 or more.

On the other hand, when the plate-like body becomes thin, the deformation increases due to the decrease in rigidity, and the probability of breakage increases. In addition, since distortion is easily transmitted, there is a concern that the image quality and flatness may deteriorate. The thicker the plate, the heavier the door structure. Therefore, the thickness of the plate-like body is preferably 1 mm or more and 3 mm or less, more preferably 2 mm. Therefore, the door structures of Examples 2 to 6 are preferable, and Examples 3 to 5 are more preferable.

In Examples 1 to 14, it can be understood that the adhesive strength is improved when the door structure includes the core material.
