  Below, the door panel which concerns on embodiment of this invention is demonstrated based on an accompanying drawing. First, a common basic schematic configuration of the door panel 10 according to the following embodiments will be described.

  The door panel 10 includes two opposing panel portions 11, 11 and frame portions 12, 12,... Provided on the four circumferences of the panel portion 11. One panel part 11 of the panel parts 11 and 11 and a part of the frame part 12 corresponding to at least one edge of the panel part 11 of the frame parts 12, 12,. At least one panel body 20 formed by folding the corrugated cardboard material is provided. As will be described later, the part of the frame part 12 corresponding to at least one edge may be a part in the thickness direction of the frame part 12 of at least one edge, or the frame part of at least one edge. It may be a part of 12 longitudinal directions. Moreover, the whole frame part 12 of at least one edge may be sufficient.

  In addition, although this door panel 10 is used as a door body of various doors, such as a sliding door, a hinged door, a folding door, and a storage door, the embodiment demonstrated below showed the example of the door panel 10 for hinged doors.

  Next, a detailed configuration of the door panel 10 according to an embodiment of the present invention will be described with reference to FIGS.

  The door panel 10 shown in FIG. 1 is formed by combining two panel bodies 20 and 20 as main members. The panel bodies 20 and 20 constitute one door panel 10 as a pair. As shown in FIG. 4, each panel body 20 includes a panel portion 21 constituting the panel portion 11 on one surface of the door panel 10, and four frame portions 12, 12,. Are integrally formed. In addition, the frame part of each edge formed in the panel body 20 constitutes a part of the frame part 12 of one edge of the door panel 10, and the both panel bodies 20 and 20 are joined to each edge. A frame portion 12 of the door panel 10 is formed. Below, in order to distinguish the frame part of the panel body 20 and the frame part 12 of the door panel 10, the frame part of the panel body 20 is called the division | segmentation frame part 22. FIG.

  Each of the two panel bodies 20 and 20 is formed by processing one cardboard material. The two panel bodies 20, 20 have the same shape, and both panel bodies 20, 20 are formed based on the unfolded material shown in FIGS. 2 and 3 (hereinafter referred to as panel material 30). In addition, although it is desirable to match | combine the longitudinal direction of the hollow part inside a cardboard material with the vertical (longitudinal) direction of the panel body 20 in consideration of an intensity | strength, it is not restricted to this. Moreover, in order to raise the intensity | strength of the door panel 10, you may distribute | arrange a hollow part so that it may orthogonally cross between both the panel bodies 20 and 20. FIG.

  The developed view shown in FIG. 2 is a plan view of the panel material 30 on the surface side forming the inner surface when the panel body 20 is molded, and the developed view shown in FIG. 3 is the panel material on the surface side forming the outer surface. FIG. 30 is a plan view of 30 (back view of what is shown in FIG. 2).

  The panel material 30 is formed by cutting rectangular pieces having the same shape at the four corners from the original rectangular material. The protruding pieces 32, 32,... On each edge of the panel material 30 are portions for forming the frame portion 12 (divided frame portion 22). The dividing frame portion 22 is formed by folding each protruding piece 32 inward along two fold lines 33, 33 provided on the inner surface. A band-shaped portion between the two fold lines 33, 33 in each protruding piece 32 is a portion for forming the side end surface of the formed panel body 20, that is, the outer surface of the divided frame portion 22. Therefore, the width dimension of this part is roughly equivalent to the thickness of the panel body 20. Moreover, the four L-shaped broken lines in the developed view of FIG. 2 correspond to the four corners of the panel body 20 to be formed.

  The fold line 33 is desirably cut by a V-cut or the like so that it can be easily valley-folded, but may be a fold line that is simply recessed in a groove shape. Further, when folding along the longitudinal direction of the hollow portion of the corrugated cardboard material, it may be a fold 33 by a mark line because it is sufficiently easy to fold without a cut or a groove.

  A band-like portion disposed on the outer side of the outer fold 33 in each projecting piece 32 is joined to another panel body 20 in the divided frame portion 22 of the panel body 20 (see FIG. 4). Reference). The outer surface of the joining portion 22a is a portion hidden by joining the panel bodies 20 together.

  As shown in FIGS. 3 (a) and 3 (b), the decorative sheet 15 (FIG. 3 (a) is cross-hatched on the entire surface of the panel material 30 except for the joint portion 22a (see FIG. 1). Is shown).

  By folding such a panel material 30 inward along the fold line 33, the panel body 20 having the vertically winning frame portion 12 (divided frame portion 22) as shown in FIG. 4A is formed. . As described above, one panel body 20 is formed so as to integrally include a panel portion 21 on one surface and divided frame portions 22, 22,.

  Since the panel part 21 and the division frame part 22 are integrally formed in the panel body 20, those boundaries do not appear on the outer surface. On the other hand, on the inner surface side of the panel body 20, the panel portion 21 is surrounded by a divided frame portion 22 that protrudes upward in the four circumferences.

  Since the divided frame portion 22 of the panel body 20 is formed so as to be vertical, the upper and lower surfaces of the divided frame portion 22 for forming the vertical frame are folded as shown in FIG. A section of the panel material 30 (corrugated cardboard material) exposed is exposed.

  Since the panel body 20 is formed by folding the four projecting pieces 32, 32,... Of the panel material 30 as described above, the thickness of the divided frame portion 22 is the original panel material. The thickness of 30 is approximately double.

  Further, a part of the middle portion in the longitudinal direction of the divided frame portion 22 for forming the vertical frame shown by a broken line in FIG. 4A is cut out by a predetermined depth from the outer surface side of the joint portion 22a. . As shown in FIG. 1, base materials 16, 16, 16 made of a wood material for attaching door metal fittings (not shown) are attached to the cut portions 22 b, 22 b, 22 b. A base material 16 for the door latch is fixed to the cut portion 22b of one of the divided frame portions 22 forming the vertical frame, and two cut portions 22b and 22b of the other divided frame portion 22 are used as the base for the hinge receiving portion. The materials 16 and 16 are fixed. In addition, when manufacturing as the panel body 20 for sliding doors, the base material for attaching a rail on the upper frame side, and the base material for attaching a door pulley on the lower frame side, the corresponding upper and lower divided frame portions 22 are provided. , 22 may be attached.

  Next, the configuration and assembly procedure of the door panel 10 using two panel bodies 20 and 20 processed and formed in this way will be described with reference to FIGS. 1 and 5.

  As shown in FIGS. 1 and 5, the two panel bodies 20, 20 are combined such that the inner surfaces face each other. One panel body 20 may be attached with the above-described base material 16 in advance. Moreover, it is desirable to attach the core material 17 as shown in FIG. 4 to the concave inner surface of each panel body 20. The core material 17 may be made of a corrugated cardboard material or a wood material, and not only the longitudinal core material 17 as shown in FIG. 4 but also a lateral core material may be mounted. A cardboard board or a wood board may be fitted into the cavity so as to fill the cavity almost without gaps. What is necessary is just to make it join the both panel bodies 20 and 20, and mounting | wearing of the base material 16 and the core material 17 using an adhesive agent.

  In this way, by using the two panel bodies 20 and 20 as main members, adding various sub-members such as the base material 16 and the core material 17 and combining them, the two panel portions 11 and 11 facing each other, The door panel 10 provided with the frame parts 12, 12,. The thickness of the door panel 10 thus formed is approximately four times as thick as the panel material 30 made of the original cardboard material.

  As described above, in order to mold the door panel 10, a cardboard material is cut and molded into a predetermined shape using a corrugated cardboard material as a main material, a decorative sheet 15 is attached to the outer surface of the material, and a crease 33 is provided at a predetermined portion. Two materials 30 may be prepared. Then, each panel material 30 is folded along the fold line 33 to form the panel body 20, a sub member is attached to the panel body 20, and the two panel bodies 20, 20 are joined to each other. The door panel 10 can be formed.

  The panel body 20 is made of a single cardboard material having a predetermined shape, and the panel portion 21 and the divided frame portion 22 are integrally formed, so that the frame portion 12 and the panel portion 11 are formed. There is no need to procure parts individually or to combine them. Furthermore, since the panel part 11 (21) and the frame part 12 (divided frame part 22) can be formed only by folding a part of the panel material 30, the door panel 10 can be manufactured very simply and quickly.

  Further, at the stage when the dimensions of the door panel 10 are received and the dimensions are determined, the development drawing of the cardboard material (panel material 30) can be generated by CAD. Further, the generation of the panel material 30 by cutting the cardboard material, the formation of the panel body 20, and the molding of the door panel 10 can be performed in a series of manufacturing steps in the factory. Therefore, it is possible to reduce the manual work on the site. As a result, the door panel 10 can be manufactured at a low cost.

  Of course, the panel material 30 may be transported to the site and assembled on site. Since the original corrugated cardboard material or the panel material 30 is a flat plate material, it is easy to carry, and even if it is stored in large quantities in that state, it does not take up space. Moreover, since there are few members which comprise the door panel 10, inventory management of members can also be made efficient.

  Moreover, since the panel body 20 is the structure by which the panel part 11 (panel part 21) and the frame part 12 (divided frame part 22) were united, the shift | offset | difference of the panel part 21 and the divided frame part 22 is these. Unless it is divided, it cannot occur. Furthermore, since the divided frame portion 22 integrated with the panel portion 21 also functions as a rib, appropriate strength can be obtained as the door panel 10 as a whole. Moreover, since the door panel 10 of this embodiment is equipped with the core material 17 inside, the further improvement in intensity | strength can also be aimed at. Further, since the cardboard material is the main member, the panel material 30, the panel body 20, and the door panel 10 are lighter than conventional wooden ones and are highly convenient for carrying on site. Since the door panel 10 is lightweight, it can be easily operated by a user after construction.

  Next, a door panel 10 according to another embodiment will be described with reference to FIG.

  This door panel 10 is also formed by uniting two panel bodies 20 and 20 processed and molded based on a cardboard material. As shown in the reduced plan view on the right side of FIG. 6A, each panel body 20 includes a panel portion 21 and frame portions 22, 22 that are formed in an L-shape by folding on two adjacent edges. Yes. That is, one panel body 20 is formed integrally with the panel section 21 corresponding to the two edges of the door panel 10, and the other panel body 20 corresponds to the other two edges. The frame portions 22, 22 are formed integrally with the panel portion 21. In addition, the decorative sheet 15 is attached to the outer surface of the panel body 20, but it is also attached to the cut surface (the side edge that is not folded) of the corrugated cardboard material as in this example. Is desirable.

  By joining these panel bodies 20 and 20 at the inner surfaces, a door panel 10 having a thickness approximately three times that of the original cardboard material as shown in FIG. 6B is formed. When this door panel 10 is also used as a hinged door, a base material 16 (see FIG. 1) and a core material 17 (see FIG. 1) for a door metal fitting may be attached.

  According to the configuration of the door panel 10 shown in FIG. 6, since the number of folding points is small, manufacturing is further simplified, and further cost reduction can be achieved.

  In the example of FIG. 6, the frame portions 22 for the two edges adjacent to each panel body 20 are formed, but the frame portions 22 for the two opposite edges may be formed. Further, a frame portion having a side length corresponding to one edge may be formed by a frame portion of two panel bodies. For example, half of the frame portion on one side may be formed on one panel body, and the other half may be formed on the other panel body. Moreover, a frame part may be provided as a continuous concave-convex shape as a frame part of the panel body, and the frame parts may be engaged with each other so that both panel bodies are combined to form a door panel. If the frame portion on one side is constituted by two panel bodies in this way, a shift between the panel bodies is unlikely to occur.

  Each of the door panels 10 according to the above two embodiments is formed by combining the two panel bodies 20, 20, but cuts one cardboard material having a predetermined shape. Instead, it may be formed only by folding and joining.

  Moreover, the door panel 10 is good also as a structure containing the wooden decorative panel (not shown). That is, for example, one panel body 20 shown in FIG. 4 and one wooden decorative panel may be bonded together to form a door panel.

  As described above, the door panel 10 is configured to have at least one panel body 20 in which one panel portion 11 and at least a portion of the frame portion 12 continuous with the panel portion 20 are integrally formed of a cardboard material. Good.
