Description

  The present invention relates to a joinery. More specifically, the present invention relates to a structure of a fitting such as a flash panel for an entrance door, in which a core material having a large number of through holes is used as a core material, and a front surface plate and a back surface plate are bonded to both surfaces.

  In recent years, as housing becomes prefabricated, standardization of housing construction materials is also progressing to meet the standard. For example, a flash panel used for an entrance door or the like has a large number of honeycomb cells made of paper and is used as a core material, and face plates are attached to both sides of the peripheral frame so as to enclose the core material. It is manufactured by. That is, a pair of horizontal frame members and a pair of vertical frame members are framed in a rectangular shape to assemble a peripheral frame, and if necessary, an intermediate frame member is installed in the peripheral frame, and the internal dimensions are set in the peripheral frame. It is manufactured by filling the core material with different dimensions.

For example, in Japanese Patent Laid-Open No. 7-217063, an expandable core raw material is arranged between a pair of rectangular plate-like original plates arranged to face each other in parallel, and an end portion of the core raw material is used as an original plate. A core raw material is formed between a pair of first frame members obtained by cutting the raw plate by integrally fixing to form a raw material for the panel, and cutting the raw material for the panel with a predetermined width in a direction perpendicular to the original plate. A panel core body in which the core material obtained by cutting is integrated is formed, and the distance between the pair of first frame members of the panel core body is set to a predetermined distance by expansion and contraction of the core material, and the first frame material The end portions of the pair of second frame members and the end portions of the first frame member that are installed so as to be orthogonal to each other are assembled to assemble the peripheral frame, and face plates are provided on both sides of the peripheral frame so as to enclose the core material. A method of manufacturing a flash panel characterized by sticking is disclosed.
JP 7-217063 A

  By the way, in the above-described conventional example, the assembly process is complicated because the frame material composed of a pair of horizontal frame materials and a pair of vertical frame materials is framed and the peripheral frame is assembled and then the core material is disposed and loaded. There is a problem of becoming. Further, since the core material is simply loaded and not fixed, the core material is displaced, so that there is a problem that a product with stable quality cannot be obtained. Further, when manufacturing flash panels having different dimensions, there is a problem that core materials having different dimensions must be prepared in addition to the frame material and face plate, and it is not possible to easily cope with the change in dimensions.

  The present invention has been made in view of the above-mentioned background art, and its purpose is to be able to be easily manufactured, to have a stable quality without shifting or moving the core material, and further required applications. Accordingly, it is an object of the present invention to provide a joinery that can be manufactured in response to a change in size and easily.

  In order to solve the above problems, a joinery according to the invention described in claim 1 of the present invention includes an opening surface of a hollow cylindrical cell of a porous core material made of an aggregate of a large number of hollow cylindrical cells penetrating in one direction. A frame block is fixed to both sides at right angles to form a core block, and then a core panel is formed by slicing and cutting the core block in the thickness direction of the core block. The required number of core panels is arranged in parallel. In addition, it is characterized in that it is sandwiched between the front decorative plate and the back plate and combined.

  Examples of the porous core material include a paper honeycomb core material in which an aggregate of a large number of honeycomb cells is formed from a paper material, a plastic honeycomb core material using plastic instead of a paper material, and a variety of light metals such as aluminum. A metal honeycomb core material or the like formed from the material is used. Moreover, a plywood is normally used as a frame board which forms a core block.

  As a surface decorative board of a fitting according to the present invention, usually woody materials such as MDF (medium density fiberboard), plywood, LVL (laminated Veneer Number), particle board, WPB (wood plastic board), particle board, laminated board, etc. A surface decorative plate is used in which a surface decorative material such as a plastic sheet or a nonwoven fabric is applied to the surface of the material and made of wood grain or various designs. Further, a thin metal plate such as a color aluminum plate or a color steel plate having a thickness of about 0.3 to 0.4 mm can be used as the surface decorative material.

  Non-decorated wood materials such as MDF (medium density fiberboard), plywood, LVL (laminated Veneer Number), WPB (wood plastic board), particle board, laminated wood, particle board, WPB, etc. Can give.

  The invention according to claim 2 of the present application is characterized in that, in the invention according to claim 1, a locking rib for locking to the lower surface of the core panel is provided on the upper surface of the back plate. . Usually, a plurality of the ribs are provided in parallel.

  In the joinery according to the first aspect of the present invention, a frame block is formed by adhering a frame plate to both surfaces of the porous core material perpendicular to the opening surface of the hollow cylindrical cell, and then the core block is formed in the thickness direction. It can be cut into any thickness by the so-called “bread method”. Therefore, when a relatively thick thickness is required, such as when the joinery is a front door, it is possible to provide a core panel cut to a width of about 40 mm and a relatively thick partition panel or the like. If not required, the core block can be cut at 10 mm width to provide a relatively thin core panel. Therefore, a core panel having a desired thickness that can be used for various fittings can be manufactured from one core block.

  The core panel obtained as described above has a frame part formed by a cut frame plate. The required number of core panels, for example, two core panels are arranged side by side so as to form a plane. By sandwiching and composing a single core panel between a front decorative plate and a back plate as a core material, a flash panel that can be used as a fitting with a good workability can be manufactured by a simple process. At this time, the frame portions that come into contact with each other in the flash panel form an intermediate frame material, and an effect as a reinforcing material can be exhibited.

  In the joinery according to the second aspect of the present invention, since a plurality of locking ribs that are locked to the lower surface of the core panel are usually provided on the upper surface of the back plate, the protrusion protrudes in the longitudinal direction of the core panel. The locking ribs provided as stripes are firmly cut into the back surface of the core panel and locked at the time of pressure bonding in the third step.

  And when the fitting C of this invention is used as a flash panel and it is used as an entrance door, the core panel contained at the time of opening and closing of the door is fixed firmly without moving in and it can prevent generating an unpleasant sound. Further, the locking rib also functions as a reinforcing rib, preventing the back plate from warping, and thus preventing the fitting of the present invention from warping.

  Hereinafter, an embodiment of a joinery according to the present invention will be described in detail with reference to the drawings, with an example using a flash panel as an example and a corrugated cardboard material as a porous core material. First, a process for manufacturing a flash panel as a fitting according to the present invention will be described. FIG. 1 is an exploded explanatory view showing a first step of the manufacturing process. As shown in FIG. 1, the porous core material 1 is an aggregate of hollow cylindrical cells 11 penetrating in one direction indicated by thin white arrows, and is made of a cardboard core material that is a paper honeycomb core material. In this first step, an upper frame plate 21 and a lower frame plate 22 are respectively disposed on the upper surface 12 and the lower surface 13 perpendicular to the opening surface of the hollow cylindrical cell 11 of the porous core material 1 and indicated by thick arrows. Or crimping under heating.

  Here, although MDF (medium density fiber board), plywood, LVL, etc. are used as the said upper-and-lower frame boards 21 and 22, in this embodiment, plywood is used. In addition, an adhesive is previously applied to the bonding surfaces of the upper and lower frame plates 21 and 22 with the porous core material 1 by a roll coater or the like, and then crimped or crimped under hot pressure.

  At this time, as an adhesive, for example, a water-based adhesive such as a vinyl acetate adhesive or an ethylene vinyl acetate adhesive, or a thermosetting adhesive such as an acrylic, urethane, urea-melamine, or the like is used for pressure bonding. Alternatively, it is firmly crimped under hot pressure. In this way, the upper and lower frame plates 21 and 22 are fixed to the upper surface and the lower surface of the porous core material 1, so that the porous core material 1, the upper frame plate 21, and the lower frame plate 22 are combined and integrated. A core block is formed.

  FIG. 2 is an explanatory view showing a second step of the manufacturing process of the joinery according to the present invention. That is, in the second step, the core panel B is manufactured by a so-called “bread baking method” in which the core block A formed as described above is sliced in the thickness direction. As shown in FIG. 2, the circular saw 5 is used as the slicing means, and the slice d is sliced to a desired thickness within a range of a thickness d of 10 to 40 mm.

  At this time, the upper frame plate 21 and the lower frame plate 22 are cut into a predetermined width. However, since the porous core material 1 is firmly bonded to the porous core material 1 under pressure or heat, it may be peeled off at the time of cutting. , Sliced together without separation. In this way, the core panel B having a desired thickness d with a thickness d within the range of 10 to 40 mm, with the upper frame plate 21 as the frame portion 21a and the lower frame plate 22 as the frame portion 22a. Is formed.

  Drawing 3 is an explanatory view showing the 3rd process of the manufacturing process of joinery concerning the invention in this application. In the third step, first, the adhesive 8 is supplied from the adhesive storage tank 7 to the roll coater 6, and the adhesive 8 is applied to the upper and lower surfaces of the core panel B. Then, the surface decorative board 3 is crimped | bonded to the upper surface of the core panel B, and the back surface board 4 is crimped | bonded to a lower surface, or it crimps | bonds under heat pressure. In addition, in the process of apply | coating the adhesive agent 8 with the roll coater 6, although a reverse roll, a scraping roll, etc. are required, illustration is abbreviate | omitted. At this time, as shown in FIG. 3, since the adhesive 8 is applied to the upper and lower opening surfaces of the hollow cylindrical cell 11 of the porous core material 1, the adhesive area is small, and the amount of the adhesive actually applied Therefore, the adhesive cost can be reduced. However, a strong adhesive force is also required with a small adhesive area.

  Therefore, the adhesive is preferably used for adhesion of wood materials, for example, water-based adhesives such as vinyl acetate adhesives, ethylene vinyl acetate adhesives, acrylics, urethanes, urea-melamines, etc. Using a thermosetting adhesive, it is pressure bonded or pressure bonded under heat. By completing the third step, the two core panels B arranged in parallel in the longitudinal direction are sandwiched by the front decorative plate 3 and the back plate 4 to be combined and integrated, and as the fitting C according to the present embodiment, A flash panel is formed.

  FIG. 4 is a perspective view showing a flash panel as a fitting C obtained by finishing the first step, the second step, and the third step. As shown in FIG. 4, the joinery C is a core material in which two core panels B are arranged in the longitudinal direction, and frame portions 21 a and 22 a that are in contact with each other in the flash panel are integrally formed. It forms an inner frame material and exhibits a reinforcing effect. In this way, by sandwiching and combining the front decorative plate 3 and the back plate 4, it is possible to produce a flash panel suitably used for an entrance door or the like with good workability by a simple process.

  FIG. 5 is an exploded explanatory view showing a modified example in the third step of the manufacturing process of the joinery according to the present invention. As shown in FIG. 5, in this modification, the back plate 4 is provided with a locking rib 41 and is locked to the lower surface of the core panel B during crimping. That is, when crimping or crimping under heat pressure, the locking rib 41 provided as a protrusion in the longitudinal direction of the core panel B firmly bites into the back surface of the core panel B and locks. 4 is prevented from shifting or moving to each other.

  In this way, when the fitting C of the present invention is used as, for example, an entrance door, the two core panels B are firmly fixed without moving inside when the entrance door is opened and closed, and an unpleasant sound can be prevented. . Further, the locking rib 41 functions as a reinforcing rib, preventing the back plate 4 from warping, and thus preventing the entrance door from warping.

  In addition, in embodiment shown in FIG. 5, although the form which the locking rib 41 protruded from the back surface board 4 is shown, you may protrude a locking rib in the back surface of the surface decorative board 3. FIG. By doing so, it is possible to produce an excellent flash panel in which the two core panels B are more firmly fixed without moving in the joinery C.

  In the above embodiment, the core block A is formed by crimping the upper frame plate 21 and the lower frame plate 22 to the upper and lower surfaces in FIG. 1, but another frame plate is further crimped to either the left or right. The core block A may be a three-sided frame block. Furthermore, it is good also as the core block A which surrounded all four surfaces with the frame board. As described above, the present invention can be modified in design, and belongs to the technical scope of the present invention without departing from the scope of the claims.
