Description

  The present invention relates to a flash panel having a flash structure in which an interior is formed hollow for use in a fitting such as a hinged door or a sliding door of a building or the like.

  Conventionally, as a flash panel used for joinery such as a building, a frame body formed in a frame shape with long square members, a honeycomb core filled in the frame body, and a plate shape bonded to both sides of the frame body and the honeycomb core There is known a so-called flash structure having a hollow inside. In this type of flash panel, frame material and surface material are formed by cutting regular square and plate materials to the required length and size, so that the end material is inevitably generated and the end material is processed. There was a problem that (disposal) is costly.

  In addition, it is difficult to change the thickness of the honeycomb core filled in the flash panel later, and it can hardly be used for flash panels (frame bodies) of different thickness. If the core is left over, there will be a problem of having extra inventory. Therefore, when manufacturing a flash panel, it is necessary to strictly calculate the amount of use of the honeycomb core so that the honeycomb core does not remain, and there is a problem that it takes time and increases the cost. In addition, in order to meet the demand for short delivery time, it is necessary to prepare honeycomb cores of various thicknesses in stock, and there is a problem in that inventory management takes time and costs increase. Alternatively, it may be possible to cut a large honeycomb core before cutting to a predetermined thickness to a thickness necessary for manufacturing a flash panel, but it is difficult to cut the honeycomb core in a good state with normal equipment. Therefore, there is a problem that a dedicated cutting facility is required and the cost for manufacturing the flash panel increases.

  To solve the above problem, a plurality of square members using end members of a frame body are bonded at appropriate intervals between a pair of plate members using end members of a surface material, and then formed into a ladder shape. A core material is formed by cutting to the same width as the thickness of the core, and this core material is placed in the frame instead of the honeycomb core, so that the strength of the flash panel is maintained and the end material is effectively used. (Patent Document 1).

  By the way, when a flash panel made of wood is used for a door, if the temperature (air temperature) difference between both sides of the door is significantly different, condensation occurs on the inside of the surface material on the lower temperature side, The surface material on the lower temperature side may wet and expand, or the surface material on the higher temperature side may dry and contract, and only one surface material expands or contracts. There were problems of warping and twisting. In contrast, by forming a vent hole in the flash panel frame that allows the hollow interior and exterior to communicate with each other, the interior of the flash panel is ventilated to allow environmental differences such as temperature differences and humidity differences between the surface materials on both sides. Has been proposed to prevent the occurrence of dew condensation and drying to prevent warping and twisting (Patent Document 2).

  However, in the thing of patent document 1, although the cost concerning disposal of an end material can be reduced, after forming the end material of a frame or a surface material in the shape of a ladder, it cuts to the required width and cuts the core material. Since it is formed, there is a possibility that the cost for forming the core material is increased, and the cost for manufacturing the flash panel may be increased.

  Further, in Patent Document 1 and Patent Document 2, since a ladder or a honeycomb core is filled as a core material, a space in which a ladder-shaped lattice or each cell of the honeycomb core is closed is used. Therefore, even if air holes are formed in the frame, it is not possible to ventilate the inside of the lattice or the cell, so the environmental difference between the surface materials on both sides cannot be reduced, and the door (flash panel) is warped or twisted. There was a problem that a problem such as Therefore, in the thing of patent document 2, the moisture-proof layer which used the polyethylene film etc. was provided in the inner surface side of the surface material, and there existed a problem which cost increased.

  SUMMARY OF THE INVENTION In view of the above circumstances, the present invention has an object to provide a flash panel that reduces manufacturing costs and is less prone to malfunction even when environmental differences occur between the surface materials on both sides.

In order to solve the above-described problems, the flash panel according to the present invention includes a pair of long bars extending in the long side direction and a short bar extending in the short side direction by connecting both ends of the pair of long bars in the long side direction. And the long beam and the short beam are each formed of square material, and a frame formed in a frame shape by the long beam and the short beam, respectively, and bonded to both sides in the thickness direction of the frame, Adhered between a surface material formed of a plate material and the surface material, and formed of a square material having the same thickness as the frame body, and in a short side direction between the pair of long bars in the frame body A plurality of first reinforcing members arranged in a straight line, and a plate material having the same width as the thickness of the first reinforcing member and the same thickness as the surface material shorter than the inner length in the long side direction of the frame body And less between each of the first reinforcing members such that the width direction is the thickness direction of the frame body. A second reinforcing material that is sandwiched between the surface materials so that a gap is formed between both ends in the longitudinal direction and the inner periphery of the frame, and the second reinforcing material Formed by a plate material having a narrower width and the same thickness as the surface material, and between the long bars and the short bars so that the width direction is the thickness direction of the frame body And a pair of the long bars formed between the pair of long bars, the pair of short bars, and the four spacer materials. The first reinforcing material, the at least one second reinforcing material, and the spacer material are sequentially arranged from one end side between the first reinforcing material and the second reinforcing material. , and is formed by sandwiching the spacer member by a pair of the long crosspiece "be characterized

  Here, the “square member” used for the frame and the first reinforcing member may be a rod-like member having a square cross section close to a square, and “timber”, “LVL (single plate laminate)”, Examples using wood such as “LVS (composite single plate laminate)”, “MDF (medium density fiberboard)”, “particle board”, and using square pipes made of metal or synthetic resin, etc. can do. Further, the “plate material” used for the surface material, the second reinforcing material, and the spacer material may be a plate-like member, such as “timber”, “plywood”, “decorative plywood”, etc. , “Metal plates”, “synthetic resin plates”, “volcanic glassy multilayer plates, inorganic plate materials such as calcium silicate plates (calcal plates)”, and the like can be exemplified.

  Adhesives used for “adhesion” include “vinyl acetate resin emulsion adhesive”, “polyvinyl acetate resin solution adhesive”, “melamine resin adhesive”, “urea resin adhesive”, “resorcinol” Adhesives, acrylic resin emulsion adhesives, α-olefin adhesives, urethane resin emulsion adhesives, aqueous polymer-isocyanate adhesives, nitrile rubber adhesives, Examples thereof include “nitrocellulose adhesives”, “phenolic resin adhesives”, “polyvinyl alcohol adhesives”, and the like.

  According to the present invention, the second reinforcing material extending in the long side direction is sandwiched between the plurality of first reinforcing materials arranged in the short side direction between the surface materials bonded to both sides of the frame. In this state, the first reinforcing material and the second reinforcing material are bonded to the surface material, and the first reinforcing material and the second reinforcing material are filled instead of the honeycomb core in the conventional flash panel. Therefore, a flash panel having the same strength and rigidity as a conventional flash panel can be obtained. Further, since it is not necessary to use a honeycomb core, it is possible to simplify the labor for inventory management and the like, and to meet the demand for a short delivery time without increasing the cost.

  In addition, the first reinforcing material disposed between the surface materials, that is, in the frame of the frame body is formed of square materials having the same thickness as the frame body, and the second reinforcing material and the spacer material are the same thickness as the surface material. Therefore, the first reinforcing member, the second reinforcing member, and the spacer member can be used as the frame member or the end member of the plate member, and the cost of the flash panel material. Can be reduced. In addition, since the plate-like second reinforcing material and the spacer material are sandwiched between the frame body and the first reinforcing material formed by square members, when the second reinforcing material or the like is bonded to the surface material The frame and the first reinforcing material can prevent the second reinforcing material and the spacer material from falling down, and it is necessary to support the second reinforcing material and the spacer material so as not to fall down when manufacturing the flash panel. In addition, the flash panel can be easily manufactured. Therefore, the cost for manufacturing the flash panel can be reduced.

  Furthermore, the spacer material having a width smaller than that of the second reinforcing material is sandwiched between the square members forming the frame and between the first reinforcing materials. A gap can be formed on the inner side of the frame body, and both sides in the long side direction of the first reinforcing member can be communicated with each other through the gap of the spacer material. In addition, since a gap is formed between both ends in the longitudinal direction of the second reinforcing material and the inner periphery of the frame, the space is divided in the short side direction by the plurality of second reinforcing materials through the gap. They can communicate with each other. As a result, the flash panel of the present invention can reliably ventilate (vent) the interior through the gap formed by the spacer material and the gap formed at both ends in the longitudinal direction of the second reinforcing material. And environmental differences such as humidity differences can be reduced.

  Therefore, in the case where the flash panel is made of wood, it is possible to suppress condensation on only one surface material or to dry it by ventilating the inside. It is possible to suppress shrinkage due to drying, and it is possible to prevent the flash panel from being warped or twisted due to expansion or contraction of the wood (surface material). In addition, when the flash panel is made of metal, it is possible to prevent condensation from occurring by ventilating the interior, so that it is possible to prevent the interior from corroding due to the condensed water. The durability of the panel can be increased. Thus, according to the present invention, even if environmental differences such as temperature difference and humidity difference occur between the surface materials on both sides, it is possible to obtain a flash panel which is less prone to problems such as warpage, twisting and corrosion.

  By the way, in a conventional flash panel using a honeycomb core, when a paper honeycomb core (also referred to as a paper core) formed of paper or cardboard is used as the honeycomb core, the paper core is compressed more than the frame body or the surface material. Because the strength is weak, when the surface material is bonded and pressed on both sides of the frame and the paper core, the paper core loses the undulation of the surface material, or it is `` day-shaped '', `` mark-shaped '', or `` The surface of the flash panel may not be a uniform flat surface because fine irregularities may be generated on the surface material between the frame portion and the paper core portion assembled in a “tab shape” or the like. When this flash panel is mirror-finished by mirror coating or the like, there is a problem that the surface swell and subtle unevenness become conspicuous and the quality of the flash panel is deteriorated. Therefore, it is conceivable to make the surface waviness and subtle irregularities inconspicuous by increasing the thickness of the surface material, but in this case, the thickness of the frame body is relative to the thickness of the flash panel. Since it becomes thinner, there is a problem that the rigidity of the flash panel is lowered and the warp tends to be warped. However, according to the present invention, as described above, the first reinforcing member and the second reinforcing member can be made of a frame member having a higher compressive strength than the paper core or the end material of the surface material. Therefore, it is possible to provide a high-quality flash panel in which undulations, subtle irregularities and the like are unlikely to occur on the surface without lowering. In addition, since the plurality of second reinforcing materials are arranged so as to extend in the longitudinal direction, the strength against warpage in the longitudinal direction in the flash panel can be increased, and the strength / A flash panel with high rigidity can be obtained.

  The length of the first reinforcing material is 1 to 5 times the thickness of the frame, or 25 to 150 mm (preferably 30 to 90 mm, more preferably 30 to 60 mm). It is desirable to do. This is because if the length of the first reinforcing material is shorter than the above, the number of the first reinforcing materials arranged in the short side direction of the frame body increases, so the first reinforcing material is sandwiched between the first reinforcing materials. This is because a problem arises in that the cost for manufacturing the flash panel increases due to the necessity of a large number of two reinforcing materials or an increase in labor for sandwiching the second reinforcing material between the first reinforcing materials. . Moreover, since the space | interval of the 2nd reinforcement material pinched | interposed between 1st reinforcement materials will become large when the length of a 1st reinforcement material is longer than the above, a surface material becomes easy to bend, and a surface is wavy. There is a problem that the quality of the flash panel is deteriorated due to subtle unevenness and the number of second reinforcing members arranged in the short side direction of the frame body is reduced, so that the conventional flash panel using a honeycomb core and This is because the same strength and rigidity cannot be obtained.

  In addition, the first reinforcing member formed of square members may be provided with a plurality of rows arranged in the short side direction of the frame body by a plurality of first reinforcing members so as to be separated from each other in the long side direction of the frame body. Increasing the number of rows can increase the strength and rigidity of the flash panel.

  Further, a reinforcing square member (for example, an auxiliary material or a corner member) may be provided at a position where a handle, a hinge, or the like is attached inside the flash panel, or at a corner portion. Further, the reinforcing reinforcing bars may be applied to the first reinforcing member arranged in the short side direction, and the second reinforcing member or the spacer member is provided between the reinforcing reinforcing member and the first reinforcing member. May be sandwiched.

  Moreover, as a magnitude | size of the clearance gap formed between the longitudinal direction edge part of a 2nd reinforcement material, and the inner periphery of a frame, it is 0.2 times-5 times with respect to the thickness of a frame, or 5 mm-50 mm. It is desirable to be within the range. When the gap between the inner periphery of the frame body is smaller than the above and the second reinforcing material is displaced in the longitudinal direction when the second reinforcing material is sandwiched between the first reinforcing materials, the end in the longitudinal direction However, there is a risk that it will not be possible to form a gap by contacting the inner periphery of the frame body, so the second reinforcing member must be placed carefully, which takes time and reduces the cost of the flash panel. This is because an increasing problem occurs. Also, if the gap with the inner periphery of the frame is larger than the above, the part that does not support the surface material will become large, so the surface material will bend easily and the strength and quality of the flash panel will deteriorate. It is.

  Moreover, as a width | variety of a spacer material, what is necessary is just a width | variety narrower than the width | variety of a 2nd reinforcement material, and it is 0.5 times-0.8 times with respect to the width | variety (width | variety of a frame) of a 2nd reinforcement material. It is desirable to set the width within the range. When the width of the spacer material is smaller than 0.5 times the width of the second reinforcing material, the adjacent second reinforcing material is likely to collapse when sandwiched between the first reinforcing materials together with the second reinforcing material. Therefore, it takes time to hold the spacer material, the second reinforcing material, and the like, which causes a problem of increasing the cost of the flash panel. Further, if the width of the spacer material is larger than 0.8 times the width of the second reinforcing material, the gap formed between the spacer material and the surface material becomes relatively narrow, and the surface material and the first reinforcing material This is because when the second reinforcing material and the second reinforcing material are bonded and fixed, excess adhesive may flow into the gap between the spacer material and the surface material and close the gap.

  In addition to the above-described configuration, the flash panel according to the present invention includes: “The two second reinforcing members are sandwiched between the first reinforcing members so as to overlap each other. One of the two second reinforcing members sandwiched between them has a length from the vicinity of one end side in the long side direction in the frame body to at least between the first reinforcing members, and the two second reinforcing members The other of the two reinforcing members may have a length from the vicinity of the other end side in the long side direction in the frame body to at least the space between the first reinforcing members.

  By the way, if the number of the second reinforcing members sandwiched between the first reinforcing members is one, a plate material having a length slightly shorter than the inner length in the long side direction of the frame is required as the second reinforcing member. Depending on the external dimensions of the flash panel, there may be cases where the end material obtained by cutting the surface material in the short side direction cannot be used as the second reinforcing material, and there is a problem that the end material cannot be utilized effectively. The number of second reinforcing members is insufficient only with the end material obtained by cutting the surface material in the long side direction, which may increase the cost for manufacturing the flash panel.

  According to the present invention, two second reinforcing members having a length from one end side in the long side direction in the frame to the first reinforcing member and a length from the first reinforcing member to the other end side in the long side direction in the frame. Is sandwiched between the first reinforcing materials, so that the end material cut in the short side direction when the surface material is taken can also be used as the second reinforcing material. It can be used sufficiently effectively, and an increase in the cost for manufacturing the flash panel can be suppressed.

  As described above, according to the present invention, it is possible to provide a flash panel that reduces manufacturing costs and is less likely to cause defects even when environmental differences occur between the surface materials on both sides.

It is a front view which shows the flash panel which is one Embodiment of this invention in the state which notched some surface materials. (A) is the AA cross-sectional enlarged view in FIG. 1, (b) is the BB cross-sectional enlarged view in FIG. It is a cross-sectional enlarged view which shows the example from which the length of the 1st reinforcement material in the flash panel of FIG. 1 differs.

  A flash panel 10 according to an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a front view showing a flash panel according to an embodiment of the present invention with a part of one surface material cut away. 2A is an AA cross-sectional enlarged view in FIG. 1, and FIG. 2B is an BB cross-sectional enlarged view in FIG. The flash panel 10 of the present embodiment is formed in a flash structure having a flat surface and a hollow interior, and is used for a suspension type sliding door in a fitting such as a hinged door or a sliding door of a building. In the drawings, the thickness of the plate material is exaggerated, and the length of the square member is shown shorter than the actual length.

  As shown in the drawing, the flash panel 10 of this example is formed in a vertically long rectangular shape when viewed from the front. The frame body 11 is formed in a frame shape with square bars, and the both sides of the frame body 11 in the thickness direction are respectively shown. It mainly includes a surface material 12 bonded and formed by a plate material. The frame 11 includes a pair of long bars 11a extending long in the long side direction, and a pair of short bars 11b extending in the short side direction by connecting both ends in the long side direction of the pair of long bars 11a. The crosspiece 11a and the short crosspiece 11b are formed in a rectangular frame shape. The long bars 11a and the short bars 11b of the frame body 11 are each formed of a rectangular bar having a rectangular cross section. The frame body 11 further includes a corner member 11c fixed to the four corners in the frame and an auxiliary member 11d that is in contact with the inner side of the long bar 11a and is fixed near the center in the long side direction. In this example, the corner member 11c and the auxiliary member 11d are formed of the same square member as the long bar 11a and the short bar 11b.

  The corner member 11c fixed to the upper corner in FIG. 1 uses a square member cut short, and is fixed so as to extend along the short bar 11b. Further, the corner member 11c fixed to the lower corner in FIG. 1 uses a square member having the same length as the short bar 11b, and is fixed so as to extend along the lower short bar 11b. Further, the auxiliary material 11d of the frame 11 uses a plurality of (four in this example) square members cut to a predetermined length, and two auxiliary materials 11d are arranged in parallel in the width direction with respect to one long bar 11a. It is being fixed so that it may extend in a long side direction in the state matched to. The auxiliary material 11d is fixed at a position where a handle is provided when the flash panel 10 is used as a door, and is symmetric with respect to an axis extending in the long side direction passing through the center of the frame 11 in the short side direction. It is fixed. In addition, in order to use the corner member 11c and the auxiliary member 11d of this example as a suspension type sliding door, the corner member 11c and the auxiliary member 11d are respectively arranged at positions suitable for attaching a suspension wheel, a handle (handle handle), a guide rail, and the like.

  Further, as shown in the figure, the flash panel 10 is formed of the same square material as the frame body 11 and is arranged in a straight line in the short side direction between the opposing auxiliary materials 11d in the frame body 11. The reinforcing member 13, the plate-like second reinforcing member 14 that is sandwiched between the auxiliary member 11 d and the first reinforcing member and between the first reinforcing members and extends in the long side direction, and the length of the frame 11 A plate-like spacer member 15 is further provided between the crosspiece 11a and the short crosspiece 11b, between the auxiliary member 11d and the first reinforcing member, and between the first reinforcing members. The first reinforcing member 13 has a length corresponding to the inner length in the short side direction in the frame body 11 (the distance between the auxiliary members 11d arranged to face each other in this example), and the thickness of the square member (frame body 11). It is cut to a length of about 3.5 times, and is arranged in such a way that the longitudinal direction is directed to the short side direction.

  The second reinforcing material 14 is formed by cutting a plate material having the same thickness as that of the surface material 12 into the same width as the thickness of the first reinforcing material 14 (thickness of the frame body 11). The first reinforcing member 13 is sandwiched between the first reinforcing members 13 so that the width direction is the thickness direction of the frame body 11 (see FIG. 2). Moreover, the 2nd reinforcement material 14 is pinched | interposed 2 each between 1st reinforcement materials 13 etc. so that it may show in figure. Specifically, as shown in FIG. 1, the other end side (lower side in the figure) from the position where the first reinforcing member 13 is arranged from the vicinity of one end side (upper side in the figure) in the long side direction in the frame 11. ) From the position closer to one end than the position where the second reinforcing member 14 (second reinforcing member 14 on one end side) and the first reinforcing member 13 are disposed. The second reinforcing material 14 having a length extending to the vicinity of the other end side in the long side direction (second reinforcing material 14 on the other end side) is long across the portion where the first reinforcing materials 13 are arranged. The first reinforcing members 13 are sandwiched between the first reinforcing members 13 so as to overlap each other in a predetermined range in the side direction. Further, as shown in FIG. 1, the second reinforcing material 14 is arranged so that both ends in the longitudinal direction do not come into contact with the frame body 11, and the end of the second reinforcing material 14 in the longitudinal direction and the frame body 11 are arranged. A gap is formed between the inner periphery and the inner periphery.

  The spacer material 15 is formed by cutting a plate material having the same thickness as the surface material 12 into a width narrower than the width of the second reinforcing material 14 (the thickness of the frame body 11), and the width direction is the frame body. 11 is sandwiched between the long beam 11a and the short beam 11b, between the auxiliary material 11d and the first reinforcing material, and between the first reinforcing materials so as to be in the thickness direction of FIG. reference). As shown in FIG. 2, the spacer material 15 is configured such that only one end side in the width direction is bonded and fixed to the inner surface side of one surface material 12, and the other surface material is connected to the other surface side. A gap is formed between the two. In this example, the spacer material 15 is formed to have a length within a range of 2 to 4 times the width of the square member forming the frame 11.

  As described above, the flash panel 10 according to the present embodiment is divided into two in the long side direction by the plurality of first reinforcing members 13 arranged in the short side direction in the frame 11. It is in the state. In addition, the auxiliary material 11d of the frame 11 and the first reinforcing material 13 and the second reinforcing material 14 sandwiched between the first reinforcing materials 13 cause the inside of the frame 11 to be plural in the short side direction (seven in this example). It is in a state of being partitioned into two). On the other hand, the inside and outside of the frame body 11 are in communication with each other by the gaps between the spacer material 15 and the surface material 12 sandwiched between the four corners of the frame body 11. Further, the first reinforcing material 13 partitions the long side direction by the gap between the auxiliary material 11d, the first reinforcing material 13, and the spacer material 15 sandwiched between the first reinforcing materials 13 and the surface material 12. The spaces are in communication. Furthermore, the space partitioned in the short side direction by the second reinforcing material 14 is in communication with the gap between the longitudinal direction both ends of the second reinforcing material 14 extending in the long side direction and the inner periphery of the frame body 11. It has become. Therefore, the flash panel 10 is in a state where the spaces partitioned by the first reinforcing member 13 and the second reinforcing member 14 in the frame 11 are in communication with each other.

  In this embodiment, the end material of the square member used for forming the frame 11 is used as the first reinforcing member 13, and a 28 mm × 30 mm square LVL (single plate laminated material) is used as the square member. Moreover, the end material of the board | plate material used for the surface material 12 is used as the 2nd reinforcement material 14 and the spacer material 15, and the board thickness 2.5mm plywood (including a decorative plywood) is used as this board | plate material. Further, a vinyl acetate resin emulsion adhesive is used as an adhesive for fixing the adhesive.

  Then, the manufacturing method of the flash panel 10 of this embodiment is demonstrated. First, a long square member is cut, and the long bars 11a, the short bars 11b, the corner members 11c, and the auxiliary members 11d for forming the frame 11 are removed. In addition, the dimension (length) of the long bar 11a and the short bar 11b is a dimension (6 mm to 10 mm larger) in which the outer dimension when assembled in the frame is slightly larger than the size (exact size) of the flash panel 10 to be manufactured. Dimension). Of the end material left over from the frame 11, the end material longer than the short bar 11b is used for the frame 11 of the next flash panel 10, and the end material of the square material shorter than the short bar 11b. The material of the first reinforcing member 13 is removed.

  Further, a plate material having a larger size than the flash panel 10 to be manufactured is slightly larger than the size (exact size) of the flash panel 10 to be manufactured, and the above-described long beam 11a and the short beam 11b are assembled into a frame. The material of the surface material 12 is taken by cutting into the same size as the outer dimensions. Then, the end material of the plate material remaining due to the material removal of the surface material 12 is cut into the same width as the thickness of the square material for forming the frame 11, and the material of the second reinforcing material 14 is removed. Further, the end material of the plate material remaining due to the material removal of the second reinforcing material 14 is cut into a width within a range of 0.5 to 0.8 times the width of the second reinforcing material 14, and the spacer material 15 Take material. In addition, when the width of the end material from which the second reinforcing material 14 is made is within the above range, the spacer material 15 is taken by the width as the end material.

  In addition, depending on the size of the flash panel 10 to be manufactured, when the square material or the end material of the plate material used for the first reinforcement material 13, the second reinforcement material 14, and the spacer material 15 is insufficient, the first-size square material or plate material is changed to the first material. The reinforcing material 13, the second reinforcing material 14, and the spacer material 15 may be removed. Further, the first reinforcing member 13, the second reinforcing member 14, and the spacer member 15 may have different lengths as long as they are within the range of performing a necessary function even if they are not the same length. .

  When material removal of the frame 11 and the surface material 12 necessary for manufacturing the flash panel 10 is completed, first, the frame is assembled with the spacer material 15 sandwiched between the long beam 11a and the short beam 11b. 11a and the short bar 11b are fixed with a tucker (staple). In addition, when fixing with a tucker, if the driving of the staples is incomplete or if burr is generated in the frame 11 due to the driving of the staples, the portion of the staples will swell even if the surface material 12 is press bonded from above. Since there is a problem of becoming a defective product, it is necessary to pay attention to the fixing work by the tucker, and it is desirable to reduce the number of hitting the tucker as much as possible. Further, when a flammable resin staple is used as the staple, the flush door can be easily discarded by incineration.

  Next, an adhesive was applied to one of the two surface materials 12 taken from the material using a known device such as a spreader on one surface (the inner surface), and then the adhesive was applied. Place it on a work table such as a surface plate so that the surface faces up. Then, on the upper side (on the adhesive) of the surface material 12 to which the adhesive is applied, the frame 11 assembled in a frame shape with the long beam 11a, the short beam 11b, and the spacer material 15 is placed, and the corner material 11c or The auxiliary material 11d is arranged at a predetermined position. In addition, you may make it apply | coat an adhesive agent to the site | part which each squares and the spacer material 15 contact | connect. Moreover, when mounting the frame 11 on the surface material 12, a jig for positioning each square member such as the long beam 11a, the short beam 11b, the corner material 11c, and the auxiliary material 11d at a predetermined position is used. Also good.

  Subsequently, a plurality of first reinforcing members 13, second reinforcing members 14, and spacer members 15 are arranged between the auxiliary members 11 d arranged opposite to each other in the frame 11. Specifically, for example, on the right side of the auxiliary material 11d fixed to the left long bar 11a in FIG. 1, the spacer material 15, the second reinforcing material 14 on one end side, and the second reinforcing material 14 on the other end side are arranged in this order. The first reinforcing material 14 is placed on the right side of the second reinforcing material 14 on the other end side after being arranged on the adhesive applied to the surface material 12 so that the width direction of each plate material becomes the thickness direction of the frame 11. The spacer 13 and the two second reinforcing members 14 are sandwiched between the reinforcing member 13 and the auxiliary member 11d. At this time, the spacer member 15 is positioned on the extension line of the first reinforcing member 13, and the second reinforcing member 14 on one end side is between the end portion on one end side in the longitudinal direction (long side direction) and the inner periphery of the frame body 11. At a position where a predetermined amount of gap is formed between the second reinforcing member 14 on the other end side, a predetermined amount of gap is formed between the end portion on the other end side in the longitudinal direction and the inner periphery of the frame body 11. It arranges in each position.

  Further, on the right side of the first reinforcing material 13 placed on the adhesive applied to the surface material 12, the spacer material 15, the second reinforcing material 14 on one end side, and the second reinforcing material 14 on the other end side are described above. The first reinforcing member 13 is disposed on the right side of the first reinforcing member 13, and the spacer member 15 and the two second reinforcing members 14 are sandwiched between the first reinforcing member 13 fixed in advance. In this way, the spacer member 15, the two second reinforcing members 14, and the first reinforcing member 13 are sequentially arranged until reaching the vicinity of the left end of the auxiliary member 11d fixed to the long bar 11a on the right side in FIG. .

  Thereafter, the distance between the right end of the rightmost first reinforcing member 13 arranged in a straight line in the short side direction and the left end of the auxiliary member 11d fixed to the right side of the frame 11 is the first reinforcing member. When the thickness is shorter than 13 and is several times the thickness of the second reinforcing member 14 or the like (four times in this example), the spacer member 15 is provided at the right end of the first reinforcing member 13 and the second reinforcing member 14 on one end side. And the second reinforcing material 14 on the other end side are sequentially inserted, and the spacer material 15 is inserted between the second reinforcing material 14 on the other end side and the auxiliary material 11d on the right side. Thereby, the spacer material 15, the second reinforcing material 14 on the one end side, the second reinforcing material 14 on the other end side, and the spacer material 15 are disposed between the rightmost first reinforcing material 13 and the right auxiliary material 11d. It will be in a clamped state.

Incidentally, when inserting the last spacer member 15 may be inserted a spacer member 15 to expand the gap by bending the long crosspiece 11a of the frame 11 to the outside. In the above description, the example in which the first reinforcing member 13, the second reinforcing member 14, and the spacer member 15 are arranged and fixed in order from the left side in the drawing has been described, but they may be arranged and fixed in order from the right side.

  Subsequently, after applying the adhesive to one surface (the inner surface) using a known device such as a spreader, the surface to which the adhesive has been applied is It mounts on the frame 11 mentioned above toward the side, the 1st reinforcement material 13, and the 2nd reinforcement material 14, and it crimps | bonds using a press machine in the state. The adhesive is applied to the entire back surface of the surface material 12, and in addition to the frame body 11, the surface of the frame body 11 in the first reinforcing material 13, the second reinforcing material 14, and the spacer material 15 The part which became the same surface can also be adhere | attached on the surface material 12. FIG. In addition, when pressing with a press, a plurality of sets of flash panels 10 may be stacked and simultaneously pressed with a press.

  When the adhesive is cured, the flash panel 10 is completed by cutting the four sides so that the outer shape becomes the exact size. In addition, when press-bonding with a press machine, the adhesive may protrude from between the frame 11 and the surface material 12 to the outside, or the frame 11 and the surface material 12 may be slightly misaligned. The flash panel 10 can be finished in a clean state by cutting the four sides. Incidentally, the external dimensions of the flash panel 10 of this embodiment are about 1911 mm in the long side direction (vertical direction), about 691 mm in the short side direction (lateral direction), and about 33 mm in the thickness direction. Has been.

  In addition, you may make it improve the appearance of a cut surface by affixing decorative sheets, such as a lip tape, on the cut surface of the outer periphery of the flash panel 10. FIG. The flash panel 10 of this example is used as a suspension type sliding door so that the upper side in FIG. 1 is the upper end, and a suspension vehicle is formed after a predetermined groove is formed in the top end (end surface) of both upper corners. The guide rail is attached after forming a predetermined groove extending in the short side direction on the lower end surface, and further, the predetermined groove is formed at a position where the handle (pull) is provided on the surface material 12. A handle bracket is attached.

  In addition, when the frame body 11 is assembled into a frame shape with a tucker, resin staples may be used, and the frame body 11 may be driven (fixed) into a portion (cutting margin) to be cut after pressing. Since there are no staples on the side), it is possible to eliminate defects due to staples (swelling of the surface material) and to facilitate incineration and disposal.

  As described above, according to the flash panel 10 of the present embodiment, between the surface members 12 bonded to both sides of the frame 11, between the plurality of first reinforcing members 13 arranged in the short side direction. The first reinforcing member 13 and the second reinforcing member 14 are bonded to the surface member 12 in a state where the second reinforcing member 14 extending in the long side direction is sandwiched between the honeycomb cores in the conventional flash panel. Since the first reinforcing member 13 and the second reinforcing member 14 are filled, the flash panel 10 having the same strength and rigidity as the conventional one can be obtained. Further, since it is not necessary to use a honeycomb core, it is possible to simplify the labor for inventory management and the like, and to meet the demand for a short delivery time without increasing the cost. Furthermore, it is possible to obtain a high-quality flash panel 10 in which undulations, subtle irregularities, and the like are unlikely to occur on the surface without lowering the rigidity as compared with a conventional flash panel using a paper core.

  In addition, the flash panel 10 of this example includes the first reinforcing member 13, the second reinforcing member 14, and the spacer member 15 that are disposed between the surface members 12, that is, within the frame 11. Since the square material and the end material of the plate material used for the material 12 are used, the cost for the material of the flash panel 10 can be reduced. Further, the plate-like second reinforcing material 14 and the spacer material 15 are sandwiched between the frame body 11 and the first reinforcing material 13 formed by square members, and the second reinforcing material 14 and the like are used as the surface material. Since the frame 11 and the first reinforcing member 13 can prevent the second reinforcing member 14 and the spacer member 15 from falling over when the flash panel 10 is manufactured, the second reinforcing member 14 is manufactured. In addition, it is not necessary to support the spacer material 15 so as not to fall down, and the flash panel 10 can be easily manufactured. Therefore, the cost for manufacturing the flash panel 10 can be reduced.

  Further, the flash panel 10 of the present example has a spacer material 15 narrower than the second reinforcing material 14 between the long bars 11a and the short bars 11b forming the frame 11 or between the first reinforcing materials 13. Since a gap is formed between the spacer member 15 and the surface member 12, the inside and outside of the frame 11 and the first reinforcing member 13 are interposed via the gap formed by the spacer member 15. Both sides in the long side direction can be communicated with each other. Further, since a gap is formed between both ends of the second reinforcing member 14 in the longitudinal direction and the inner periphery of the frame body 11, the plurality of second reinforcing members 13 divide in the short side direction through the gap. The spaces created can be communicated with each other. Accordingly, the inside can be surely ventilated (ventilated) through the gap formed by the spacer material 15 and the gap formed at both ends in the longitudinal direction of the second reinforcing material 14, so that the temperature difference and humidity difference of the surface material 12 on both sides Environmental differences can be reduced. And, since it is possible to suppress the occurrence of condensation or drying only on one surface material 12, it is possible to suppress the moisture from expanding due to condensation and expanding or contracting due to drying. It is possible to prevent the flash panel 10 from warping or twisting due to the expansion or contraction of the (surface material 12).

  Further, according to the flash panel 10 of this example, the length from one end side in the long side direction in the frame 11 to the first reinforcing member 13 and the other end in the long side direction in the frame 10 from the first reinforcing member 13. Since the two second reinforcing members 14 having a length up to the side are sandwiched between the first reinforcing members 13 and the like, the length of the length cut in the short side direction when the material of the surface material 12 is taken. A short end material can also be used as the second reinforcing material 14, and the end material can be sufficiently effectively used to suppress an increase in cost for manufacturing the flash panel 10.

  In addition, an adhesive is applied to the entire surface of the surface material 12 so as to adhere to the frame 11, the first reinforcing material 13, and the second reinforcing material 14. The surface material 12 can be covered with an adhesive, so that even if condensation occurs inside the flash panel 10 or is dried, the surface material 12 is wetted or dried by the cured adhesive layer. Thus, the flash panel 10 can be prevented from causing problems such as warping and twisting.

  In addition, even if the length of the some 1st reinforcement material 13 is not made into the length corresponding to the space | interval (short side direction inner length) of the auxiliary materials 11d opposingly arranged, the 1st reinforcement material 13 of arbitrary length is used. The degree of freedom of material removal with respect to the first reinforcing member 13 can be increased, the labor of material removal can be simplified, and the end material can be used more efficiently, and the flash can be used. The cost for manufacturing the panel 10 can be reduced.

The spacer material 15 is preferably arranged so as to be in contact with either the frame body 11 (auxiliary material 11d) or the first reinforcing material 13, and thereby formed between the spacer material 15 and the surface material 12. Since the length of the gap can be shortened as much as possible, such as the length of the frame 11 and the spacer material 15 overlapping, the width of the first reinforcing material 13, etc. However, the air permeability in the long side direction can be improved.

  Furthermore, in the above-described embodiment, the first reinforcing members 13 are arranged in a single line in the short side direction in the vicinity of the center in the long side direction. However, the present invention is not limited to this. A plurality of rows of the first reinforcing members 13 may be provided apart from each other in the long side direction of the frame body 11, and the same effects as described above can be obtained, and the strength and rigidity of the flash panel 10 can be obtained. Can be further enhanced.

  In the above embodiment, the frame 11 and the surface material 12 constituting the flash panel 10 are made of wood such as LVL or LVS. However, the present invention is not limited to this. Metal, synthetic resin, etc. may be used as the material used for the above, and in addition to having the same effects as described above, when metal is used for the material, condensation occurs by ventilating the interior as described above. Therefore, the inside of the flash panel 10 can be prevented from being corroded by the condensed water, and the durability of the flash panel 10 can be improved.

  Moreover, in said embodiment, although the structure of the frame 11 in the flash panel 10 showed what was suitable for using for a suspension type sliding door, it is not limited to this, Other types of sliding doors, It is good also as a structure of the frame 11 corresponding to a hinged door and also a glass door.
