Description

  The present invention relates to a composite structure including a resin structure and a metal plate used for building members such as wall materials, floor materials, and roof materials, and a method for manufacturing the same.

  Conventionally, as a board mainly made of polypropylene resin, a synthetic resin cap sheet having a plurality of protruding caps, a synthetic resin back sheet bonded to the bottom side of the cap with an adhesive, and the top side of the cap 2. Description of the Related Art There is known a technique for manufacturing a plastic foam board by forming a liner sheet made of a synthetic resin to be laminated on a laminate (see, for example, Patent Document 1).

  In addition, for example, a calcium carbonate foam plate is bonded to both the front and back surfaces of an inorganic plate-shaped core formed into a concavo-convex surface shape via an epoxy adhesive, and a steel plate (face plate) via an epoxy adhesive on the outside. ) Is also known (see, for example, Patent Document 2). If the outer surface side is made of plastic as described above, the hardness of the plastic is not high, and there is a risk of whitening if the surface is scratched. However, as described above, the outer surface should be a metal plate. Thus, the fear can be solved.

  In the conventional case, since the plate core is simply bonded by an adhesive, the plate core is bonded to the adhesive and the adhesive to the synthetic resin back sheet, liner sheet or calcium carbonate foam plate, There is no increase in the adhesion area before and after, and it depends on the bonding strength of the adhesive. For this reason, the adhesive area of the plate-like core is increased in advance so as to be bonded. When bonding a resin structure with a synthetic resin-like standing body and a metal plate by such an adhesion method, the optimum adhesive is different between the two because the materials are different from each other. It was difficult to get power. In addition, since the resin structure is a form having a standing body and a form different from the planar shape, the adhesive area is small and sufficient adhesive force is not obtained, so that it is easily peeled off.

In addition, since it is necessary to transmit stress through an adhesive (layer), strong bonding is desired.

FIG. 1A is a longitudinal front view showing a state in which the wall portion tip 9 side of the standing body 8 in the resin structure 2 is welded to the metal plate 3, and FIG. 1B is an enlarged view of the portion A in FIG. FIG. 2 is a perspective view of a composite structure composed of the resin structure and metal plate shown in FIG. 1, and FIG. 3A is a front end of a wall portion of the resin structure for producing the composite structure. FIG. 3B is a longitudinal front view showing a separated state immediately before the side is welded and bonded to a heated metal plate, FIG. 3B is an enlarged front view showing the B part of FIG. 4A, and FIG. And (b) is a longitudinal sectional front view showing a state in which a wall end of the resin structure is pressed by a metal roll when it is bonded to a heated metal plate.

  The composite structure 1 of the present invention is plate-like as a whole, and any of the front and back sides of a resin structure 2 (details will be described later) having a plurality of standing bodies 8 formed by wall portions 7 rising from the base surface used for the composite structure 1 is used. One side or both sides of the front and back are welded to a metal plate via an adhesive. In the composite structure 1 of the first embodiment shown in FIGS. 1 to 4, the resin structure 2 is arranged on one side in the plate thickness direction, and the first metal plate 3 is arranged on the other side. Then, the wall portion distal end 9 side of the cylindrical standing body 8 composed of the wall portion 7 rising from the base surface 15 in the resin structure 2 is added to the heated first metal plate 3 via the adhesive 5. Pressed, melted and welded.

The form for manufacturing the composite structure 2 may be manufactured continuously or intermittently. For example, the composite structure 1 in which the resin structure 2 and one surface thereof are welded to one metal plate is used. In the case of manufacturing, in the case of manufacturing by a manufacturing mode as shown in FIGS. 4A and 12B, or when manufacturing a resin structure in which both front and back surfaces of the resin structure 2 are welded to a metal plate, What is necessary is just to make it manufacture with the form shown to Fig.12 (a). Briefly explaining FIG. 12, in the case of FIG. 12 (b), adhesive application such as an adhesive application roller or an adhesive spraying device is applied to one surface of the strip-shaped first metal plate 3 fed out from the first coil 20. The adhesive 5 is applied by means 21 to form a band-shaped first metal plate 3 with an adhesive, and this is along the belt-shaped resin structure 2 fed out from the reel 22 around which the resin structure is wound. The metal plate is heated to a temperature close to the melting point of the belt-shaped resin structure 2 by the heating furnace 23 or the like. Further, by pressing the metal plate with the upper and lower metal rolls 17, the adhesive surface side of the belt-shaped resin structure 2 in contact with the metal plate is melted, and the upper and lower driven by a driving device (not shown). The belt-shaped resin structure 2 is welded to the belt-shaped first metal plate 3 by being pressed by the metal roll 17.
In the above case, the metal roll 17 on the side in contact with the belt-shaped resin structure 2 does not particularly require heating or the like, but as a heating means for another metal plate 3 to be further added, the metal roll 17 is in contact with the metal plate. By heating the roll 17 to + 5 ° C. to + 15 ° C. from the melting point of the resin structure 2, the surface to be welded in the belt-shaped resin structure 2 in contact with the heated metal plate is melted and pressurized to be in close contact. A continuous strip-shaped composite structure 1 may be manufactured by welding in the state of being made to adhere. After the metal plate 3 is welded to the resin structure 2 through the adhesive 5 by the above means, the metal plate 3 is cut to a predetermined length by a cutting device such as a traveling cutting machine and cooled by means such as air cooling or water cooling. Thus, the composite structure 1 having a predetermined length is manufactured.
In addition, when welding the base back surface side of the continuous strip-shaped resin structure 2 to the strip-shaped metal plate, the metal plate is provided from the lower side of the strip-shaped resin structure with the guide rolls 24 appropriately. The metal plate may be heated by the heating furnace 23 and pressed by the metal roll 17 toward the resin structure 2 so that the base back side of the resin structure 2 is melted and welded.

  In addition, by contacting the heated first metal plate 3 in a pressurized state, the wall end portion 9 of each standing body 8 in the resin structure 2 is melted, and the first portion is passed through the adhesive. The second metal plate is welded to the metal plate 3 and brought into contact with the heated second metal plate 4 in a pressurized state to melt the base back surface 10 in the resin structure 2 and through an adhesive. When the composite structure 1 is welded to 4, the composite structure 1 is as shown in FIG. In the case of FIG. 12 (a) and FIG. 26 (a) showing an enlarged part thereof, the second metal plate 4 in the form of a strip fed out from the second coil 25 is further added to the form of FIG. 12 (b). On one side, the adhesive 5 is applied by an adhesive applying means 21 to form a band-shaped second metal plate 4 with an adhesive, and this is formed from a reel 22 around which the resin structure is wound. 2, the second metal plate 4 is heated to a temperature close to the melting point of the belt-shaped resin structure 2 by a heating furnace 23 or the like. Moreover, the adhesive surface side of the strip-shaped resin structure 2 is melted by a heated metal plate, and is pressed (or heated / pressurized) by the upper and lower metal rolls 17 to form the first strip-shaped metal plate 3. The belt-shaped resin structure 2 is welded to the substrate. In this case, since the amount of heat of welding on the base rear surface 10 side is required more than welding on the upright body 8 side, the first metal plate 3 on the upright body 8 side of the belt-shaped resin structure 2 is contacted. The metal roll 17 on the side is lower by about 0 ° C. to −5 ° C. than the melting point of the resin structure 2 and is in contact with the second metal plate 4 on the base back surface 10 side of the belt-shaped resin structure 2. Is preferably higher by + 5 ° C. to + 15 ° C. than the melting point of the resin structure 2.

When the adhesive application surface side of the resin structure 2 is melted by pressing to the heated metal plate and brought into contact with the metal plate and welded by pressurization, the adhesive surface side of the resin structure is melted. May adopt any of the following forms (1) to (3).
(1) A mode in which the adhesive roll side of the resin structure 2 is melted by the heated metal plate by heating the metal roll contacting the first metal plate 3 or the second metal plate 4.
(2) The heating furnace 23 is a hot-air heating furnace in which hot air is blown to heat the metal plate, and the resin structure is passed through the heating furnace together with the metal plate, thereby heating the metal plate and pressure-bonding to the heated metal plate. Thus, the adhesive application surface side is melted, and the metal roll may be used as a pressure roll.
(3) The heating furnace 23 is a heating furnace that heats a metal plate by high-frequency induction heating. The resin structure is passed along with the metal plate in a high-frequency induction heating device, thereby heating the metal plate and crimping to the heated metal plate. Thus, the adhesive application surface side is melted, and the metal roll may be used as a heating and pressure roll.

  Instead of the continuous first metal plate 3 and second metal plate 4 and resin structure 2, the first metal plate 3, second metal plate 4 and resin structure 2 are replaced with a short rectangle or A bonded end of the resin structure 2 is melted by press-bonding a rectangular shape or the like in a predetermined final product size form to a heated metal plate (first metal plate 3 and second metal plate 4). Then, the metal plate and the metal plate may be pressed from the outside and pasted together.

  Hereinafter, when one side of the resin structure 2 is formed into a resin structure in which the resin structure 2 is welded to the metal plate via the adhesive 5, or both the front and back surfaces of the resin structure 2 are welded to the metal plate via the adhesive 5. Will be described in detail.

  One form in which the resin structure 2 and the first metal plate 3 shown in FIG. 1a and FIG. 3 (a) are welded is shown in FIG. 4 (a) and FIG. The upper metal roll 17 heated by the first metal plate 3 coated with the adhesive 5 forming the adhesive layer on the upper surface passing through the heating furnace 23 or in addition thereto is heated. The metal plate 3 is in a state heated to at least the melting point of the resin structure 2. As the heating means for the first metal plate 3, the upper surface of the first metal plate 3 is heated higher than the melting point of the resin structure 2 with the application surface coated with the adhesive 5 as the lower surface. When the upper metal roll 17 is pressed (or a short composite structure is manufactured, as shown in FIG. 26 (b), it is placed on the heating contact plate 16 in the contact heater for a predetermined time. ), The first metal plate 3 can be heated to at least the melting point of the resin structure 2. Since the heating temperature of the metal plate such as the first metal plate 3 is not uniform throughout the material of the resin structure 2, melting occurs locally at a temperature below the assumed melting point, The melting point (° C.) of the resin structure 2 is set in a range of approximately ± 10 ° C. For example, when the resin forming the resin structure 2 is an olefin resin and the melting point is 170 ° C., the temperature is set in the range of 160 ° C. to 180 ° C., for example, in the range of around 170 ° C. The temperature (° C.) of the metal roll 17 (or the heating contact plate 16) is set slightly higher than the temperature 170 ° C., for example, although it depends on the manufacturing method.

  And after making the standing body 8 side of the resin structure 2 contact | abut to the adhesive application surface of the heated 1st metal plate 3, an appropriate pressurizing force is applied with the metal roll 17 for pressurization, The said metal The roll 17 is rotationally driven by a driving device (not shown) (rolling in the form using the heating contact plate 16 in FIG. 26b), so that the pressure is applied from the outside of the resin structure 2 and the metal rolls 17 ( Alternatively, the first metal plate 3 and the resin structure 2 on the heating contact plate 16 are pressed from the outside. At this time, the wall end portion 9 of the cylindrical upright body 8 in the resin structure 2 is pressure-bonded to the first metal plate 3 via an adhesive, so that the heat of the first metal plate 3 In the state in which the wall tip 9 is heated to the melting point or higher and melted, and the wall tip 9 is crushed to form a widened wall 7a to increase the welding area. The tip 9, the adhesive 5, and the first metal plate 3 are brought into close contact with each other so that the resin structure 2 is welded to the first metal plate 3. In the above case, the base surface 15 on the side of the standing body 8 of the base 12 in the resin structure 2 is prevented from being melted by the heat of the first metal plate 3.

  In the above case, the pressing time by the metal roll 17 after the resin structure 2 is brought into contact with the metal plate 3 (4) and the thickness of the adhesive 5 are set by design. Depending on the thickness of the metal plate 3 (4) and the adhesive, the thickness of the adhesive 5 is, for example, in the range of 3 to 20 μm, and the pressurizing time is about 0.05 seconds to 1 second. Set to After welding, the composite structure 1 is cooled by blowing with a blower or a mist cooler as appropriate.

  In the composite structure 1 of the second embodiment shown in FIGS. 5 to 7, the base back surface 10 side of the resin structure 2 is welded to the second metal plate 4. It is the form which only the resin structure 2 in FIG. In this embodiment, the adhesive 5 is applied to the base back surface 10 of the resin structure 2 to provide an adhesive layer, and the base of the resin structure 2 is applied to the heated adhesive application surface of the first metal plate 4. The back surface 10 is brought into contact. After that, the second metal plate 4 and the resin structure 2 are pressurized from the outside, for example, at 40 kg / m, and the wall-raised back surface portion 18 on the base back surface 10 included in the resin structure 2 is changed to the first via the adhesive 5. By crimping to the second metal plate 4, the wall standing back surface portion 18 of the base back surface 10 is particularly melted by the heat of the second metal plate 4, and the wall standing back surface portion 18, the adhesive 5, and the second metal plate are melted. 4 and the resin structure 2 and the second metal plate 4 are welded. In this case, the standing body 8 in the resin structure 2 does not come into contact with the second metal plate 4 and does not melt. The wall standing rear surface portion 18 is the base rear surface 10 side on the base rear surface 10 side, and is a portion on the base rear surface side of the upright body 8, and the base metal back surface 10 side of the resin structure 2 is the second metal plate 4. In the case of melting using the heat of the heat and welding by pressurization, the portion extending the vertical body 8 to the back side of the base portion is melted particularly by the pressure and heat, so that the proximal end side of the vertical body 8 is A widened wall portion 7a whose width dimension gradually increases toward the metal plate side is formed in the portion closer to the base rear surface side, and the area to be welded by pressurization increases. Therefore, the base back surface 10 side of the resin structure 2 having the upright body 8 can be reliably welded, and the bonding strength can be improved as compared with the case where the bonding strength is not melted. The base back surface 10 other than the widened wall portion 7a may be welded. However, since the applied pressure is transmitted to the base back surface via the standing body 8, the wall standing back surface portion 18 is firmly welded. Adhesive strength can be obtained.

  As described above, by welding one side of the resin structure 2 to the heated metal plate 3 (4) via the adhesive 5, the composite structure 1 of the first and second embodiments of the present invention and Has been. In the composite structure 1 of the present invention, one sheet or two sheets of metal structure 2 provided with an upright body 8 and one or two metals provided via an adhesive 5 by welding one or both sides thereof. Consists of plates.

Next, the form which manufactured the composite structure 1 which consists of a resin structure and a metal plate by welding the front and back both sides of the resin structure 2 to the 1st metal plate 3 and the 2nd metal plate 4, respectively is demonstrated. . As described above, the composite structure 1 having the metal plates on the front and back sides of the resin structure 2 sandwiches the front and back sides of the resin structure 2 between the metal plates 3 and 4 that are coated with the adhesive and heated. At the same time, the composite structure 1 may be manufactured by welding by heating and pressurization. In this way, the manufacturing efficiency can be improved and the composite structure 1 can be manufactured at low cost.
In addition to the method described above, for example, any one of the methods for producing a composite structure including the resin structure 2 and the metal plate 3 (4) as shown in FIGS. After the composite structure 1 having the metal plate 3 (4) on one side of the resin structure 2 is manufactured by the composite structure manufacturing method, the composite structure 1 having the metal plate on one side thereof is used. The other side where the metal plate 3 (4) is not provided is welded to the separate metal plate 4 (3) via the adhesive 5 so that each wall end 9 of the resin structure 2 is bonded to the adhesive 5. It is also possible to manufacture the composite structure 1 in which the wall standing back surface portion 18 of the base back surface 10 in the resin structure 2 is welded to the metal plate 4 via the adhesive 5.

More specifically, after producing a continuous composite structure 1 having a metal plate 3 (4) on one side of the resin structure 2, as shown in FIG. The continuous composite structure 1 in which both sides of the resin structure 2 are welded so as to be covered with the metal plate is manufactured by heating the welded metal plate 4 (3) and pressurizing and welding the two from the outside. Can do.
Or after manufacturing the short composite structure 1 provided with the metal plate 3 (4) on one side of the resin structure 2, the composite structure 1 is inverted, and on the heating contact plate 16 in the contact heater, By placing a separate short metal plate 4 (3) coated with an adhesive 5 on the upper surface and welding the resin structure 2 in the composite structure 1 to the separate metal plate 4 (3), a resin is obtained. The composite structure 1 welded so as to cover both sides of the structure 2 with a metal plate can be manufactured.

  Here, each member used in the present invention will be described.

  As the metal plates 3 and 4, a steel plate, an aluminum alloy plate, a stainless steel plate, a zinc alloy plate, a copper plate, or another metal plate may be used, or a metal plate having a surface plated may be used. Also good. As the metal plates 3 and 4, continuous or short plate-like or sheet-like metal plates may be used. The plate thickness dimension of the metal plates 3 and 4 is appropriately set by design depending on the place of use such as a flooring material or a roofing material in a building part.

  It is desirable that the metal plates 3 and 4 are appropriately grounded before applying the adhesive. An adhesive that is activated by heat may be used. As the adhesive that is activated by heat, for example, an epoxy adhesive, a polyester adhesive, a urethane adhesive, or the like may be used.

  Next, various forms of the resin structure 2 used in the composite structure 1 of the present invention will be described with reference to the drawings. When implementing this invention, as the said resin structure 2, a continuous form or a short form may be sufficient, for example, olefin resin, such as a polypropylene resin and a polyethylene resin, and another synthetic resin are used. As for the thickness dimension of the resin structure 2, the plate thickness and the like are appropriately set by design depending on the place where the flooring or roofing material in the building part is used.

  For example, as shown in FIGS. 18A, 18 </ b> B, 19 </ b> C, 19 </ b> A, 19 </ b> B, and 19 </ b> C, the resin structure 2 includes a flat plate-like base portion 12, and from the surface of the base portion 12. The wall part 7 which stands up is provided integrally. When the wall portion 7 has a cylindrical shape, a plurality of cylindrical standing bodies 8 are formed by the wall portion 7 at intervals in the front-rear direction and the left-right direction, or FIG. (B) As shown in (c), a plurality are formed so as to be continuous in the front-rear direction and the left-right direction.

  More specifically, referring to each drawing, in the form shown in FIGS. 18A, 18B, and 18C, a peripheral side wall having a circular cross section is formed so as to rise in a cylindrical shape from the surface of the plate-like base 12. The cylindrical standing body 8 by the integrally formed wall part 7 is formed in a staggered arrangement at intervals in the front-rear direction (member longitudinal direction) and the left-right direction (member width direction) of the plate-like base part 12, Further, a through-hole is formed in the flat plate portion of the base portion 12 concentrically with the upright body 8 so as to form a cylindrical upright body 8 that penetrates the base portion. In the above-described embodiment, the vertical body 8 is arranged with an equiangular interval (in the illustrated embodiment, an equal angular interval of 60 °) around the single standing body 8 as a center. ing. The thickness of the wall 7 is made smaller than that of the base 12, and the wall thickness is gradually reduced toward the wall tip 9.

  In the resin structure 2 shown in FIGS. 19 (a), (b), and (c), the portion different from the form shown in FIGS. 18 (a), (b), and (c) is the tip of the wall portion 7. The top plate portion 13 connected to the portion 9 is provided, the tip of the wall portion of the wall portion 7 is closed by the top plate portion 13, and the standing body 8 including the top plate portion 13 is formed as a cap-shaped protrusion 14 as a whole. Is different. 19 (a), 19 (b), and 19 (c), the wall portion 7 has a top plate portion 13 formed integrally with the tip portion 9 of the wall portion, and the entire circumference of the peripheral side wall of the standing body 8 is provided. By forming the top plate portion 13 from the wall tip portion 9, a plurality of cap-shaped protrusions 14 bulging from the base surface in a hollow shape are formed. The plate thickness dimension of the top plate portion 13 is smaller than the plate thickness size of the wall portion 7.

  In the resin structure 2 shown in FIGS. 20A, 20 </ b> B, and 20 </ b> C, the wall portion 7 includes a wall portion 7 that is continuous in the front-rear direction so as to rise from the base portion 12, and a left-right direction in the member width direction. The wall portions 7 are formed so as to be spaced apart and intersect at right angles, so that the continuous standing bodies 8 having a common peripheral wall with the adjacent standing bodies 8 are used. It is set as the resin structure 2 of the form which formed.

  As described above, when the standing body 8 in the resin structure 2 is a cylindrical standing body 8 that penetrates both the front and back surfaces of the resin structure 2, the front and back surfaces of the resin structure 2 are By welding to the metal plates 3 and 4 respectively, the standing space 8 and the metal plates 3 and 4 on the front and back sides can form a sealed space 6 that is pressurized jointly. Further, as in the embodiment described later, the wall tip end portion 9 side of the cylindrical standing body 8 is closed by the top plate portion 13 and is pressed to melt the wall standing back surface portion 18 on the base back surface 10 side. In the form welded to the metal plate, the sealed space 6 pressurized inside the cylindrical upright body 8 can be formed.

  Hereinafter, the composite structure 1 in which the front and back sides of the resin structure 2 are welded to the metal plates 3 and 4 will be described in more detail with reference to the drawings.

  FIGS. 8-10 shows the composite structure 1 which consists of the resin structure and metal plate of 3rd Embodiment of this invention manufactured by the above methods, Comprising: FIG. 8 (a) is FIG. FIG. 9 is a longitudinal front view of the composite structure 1 made of a resin structure and a metal plate, FIG. 9B is an enlarged front view showing the E portion of FIG. 9A, and FIG. 9 is a composite made of the resin structure and the metal plate. FIG. 10A is a perspective view of the structure 1, FIG. 10A is a longitudinal front view showing a separated state immediately before the resin structure of the third embodiment of the invention is welded and bonded to a metal plate, and FIG. It is a vertical front view which expands and shows the F section of.

  In the composite structure 1 of the third embodiment, the resin structure 2 including a plurality of standing bodies 8 formed by the wall portions 7 rising from the base surface 15 of the base portion 12 is disposed at the center portion in the plate thickness direction. In addition, both the front and back surfaces of the resin structure 2 are portions of the adhesive 5 forming the adhesive layer provided on the heated first metal plate 3 and the second metal plate 4, and the first The metal plate 3 and the second metal plate 4 are welded and integrated.

  In the present invention, due to the structure of the resin structure 2, the resin structure 2 and the metal plate are jointly bonded to each other by welding the resin structure 2 to at least one metal plate via the adhesive 5. It can also be set as the form which forms the sealed space 6 pressurized to the state exceeding 1 atmosphere. In 3rd Embodiment, the wall part front-end | tip part 9 of the cylindrical standing body 8 by the wall part 7 which stands up from the base part surface 15 (refer FIG. 10) of the resin structure 2, and the base back surface of the resin structure 2 10 is sandwiched and welded between the first metal plate 3 and the second metal plate 4 so that the inside of the cylindrical upright body 8 is the sealed space 6. When the air pressure in the sealed space 6 is normally assumed to be used under atmospheric pressure, the internal pressure due to the air pressure in the sealed space 6 is increased by making the air pressure higher than the atmospheric pressure of 1 atm. Thereby, the initial tensile stress is previously introduced into the standing body 8, the first metal plate 3, and the second metal plate 4 formed of the wall portion 7 surrounding the sealed space 6. As a result, when an out-of-plane bending force is applied, the rigidity is increased by preventing the deformation until the initial tensile stress is canceled, resulting in increased buckling or local buckling. It does not occur. The internal pressure due to the air pressure generated by the air in the sealed space 6 is set to be higher than the atmospheric pressure of the place where it is used. The air pressure in the sealed space 6 is set to, for example, 1 atm (101325 Pa = 760 mmHg (Torr)) <the air pressure in the sealed space 6 ≦ 1.1 atm to 2.0 atm. Note that the air pressure in the sealed space 6 is pressurized and welded, and blown and cooled by a blower, a mist cooler or the like, so that the resin structure 2 and the metal plate 3 (4) contract. (The resin structure 2 has a larger coefficient of thermal expansion than the metal plate), and the standing body 8 of the resin structure 2 may be slightly smaller, and the pressure in the sealed space 6 is increased. To ensure welding. The air pressure in the sealed space 6 can be adjusted by changing the height accompanying the melting of the resin structure 2 at the time of applying pressure and pressurization.

  In the present invention, when the resin structure 2 is welded to the metal plate, for example, by heat of the heated metal plate, the portion to be bonded by pressure welding in the resin structure 2 is melted and the resin structure 2 or the height of the vertical structure 8 in the resin structure 2 (the height of the wall 7) is slightly smaller than that before heating and pressurization, so that the resin structure 2 or the wall 7 thereof It is desirable to make the resin structure 2 in which the height dimension in the axial direction of the upright body 8 is increased in advance because the height dimension is reduced. By doing in this way, the air pressure by the air in the sealed space 6 is increased, and the welding is completed in that state, so that the standing body 8 and the first metal plate 3 and the second metal plate surrounding the sealed space 6 are obtained. An initial tensile stress can be introduced into 4 in advance. In addition, the air pressure in the sealed space 6 can be easily increased by welding the metal plates 3 and 4 and the resin structure 2, and the composite structure 1 including these can be manufactured at low cost. is there. When the metal plate is a thin plate, it is possible to form a bulge 11 (see FIGS. 11 and 12) in which the metal plate bulges in the out-of-plane direction by the expansion force of the air in the sealed space 6. When a bending force in the out-of-plane direction acts on the composite structure 1, the composite structure 1 can be made to have high rigidity so that local buckling or buckling is difficult. Further, when the air pressure in the sealed space increases from 1 atm, the resonance frequency of the metal plate bonded to the back surface or the front and back surfaces of the resin structure 2 is increased. The sound insulation performance as a whole composite structure is improved by the rigidity law.

  As described above, in the present invention, the metal plates 3 and 4 do not bulge due to the air pressure in the sealed space 6 in the standing body 8 or due to the plate thickness of the metal plate, and bulge in a circular arc shape or the like. May be. For example, in the case of a predetermined thick plate so as not to bulge and deform, a tensile force is applied to the metal plates 3 and 4 of the sealed space 6 by the air pressure in the sealed space 6. Further, in the case of a sheet-like thin metal plate, a bulge 11 (see FIGS. 11 and 12) that bulges into a cross-sectional arc shape by air pressure and that bulges into a cross-sectional arc shape by air pressure In addition, a tensile force is applied. Since the thin metal plates 3 and 4 form the bulge 11 as described above, when the bending force is applied, the bulge 11 portion has a distance from the neutral axis X (see FIG. 21). r ′) is advantageous in that the rigidity increases in proportion to the third power of the distance compared to the distance (r) in the case where the bulge 11 is not provided, and the expansion force due to the air pressure in the sealed space 6 further acts. Thus, since the initial tensile force acts on the bulge 11 portion, even if a compressive force due to a bending force acts, the bulge 11 portion acts advantageously in that no deformation occurs until the initial tensile force is canceled out by the compressive force. To do.

  In the form shown in FIGS. 8 to 10, the wall portion distal end 9 side or the base rear face 10 side (particularly, the portion to be pressurized) of the standing body 8 of the resin structure 2 in the form shown in FIG. At the same time, the first metal plate 3 or the second metal plate 4 to which the adhesive 5 has been applied and heated is applied to both sides of the vertical portion 8 of the body 2 on the side of the wall tip end portion 9 or the base rear surface 10. It is the form welded on both sides. Alternatively, the wall tip end 9 side or the base back 10 side (particularly, the portion to be pressurized) of the upright body 8 of the resin structure 2 is placed on the heating contact plate 16 in the contact heater for heating one side at a time. It is placed on the first metal plate 3 or the second metal plate 4 that is placed, heated and coated with the adhesive 5, and is pressed and pressed from above the resin structure 2. It is a form in which it is melted and welded via the adhesive 5 by being sandwiched between the heated contact plate 16 and a metal roll for pressurization by a roll.

  The wall tip 9 and the base back 10 (particularly the base back side of the wall 7) side of the resin structure 2 are heated and melted by the heated metal plates 3 and 4 and are used for pressurization. By being pressed by the metal roll, the melted portion is crushed to form the widened wall portion 7a, and the welded portion is welded in an increased area. Therefore, the welding between the resin structure 2 and the metal plates 3 and 4 can be made strong. In addition, since melting by heat conduction from the heated metal plates 3 and 4 to the resin structure 2 is gradually progressed, the widened wall portion 7a is gradually wall portion toward the welded portion. Therefore, the welding is surely and firmly performed.

  Further, the widened wall portion 7a is formed so that the wall thickness dimension of the wall portion gradually increases toward the welded portion, so that the stress from the resin structure 2 to the metal plates 3 and 4 is increased. Or transmission of stress from the metal plates 3 and 4 to the resin structure 2 can be smoothly transmitted. Further, in the welded portion between the metal plates 3 and 4 and the resin structure 2, since the distance between the walls of the standing body 8 is reduced, the span of the metal plate portion between the walls is also reduced, and the rigidity of the metal plate in that portion is reduced. As a result, it is possible to reduce the deformation when the bending force is applied.

  When manufacturing the composite structure 1 of the resin structure 2 and the metal plates 3 and 4 such as steel plates as described above, the resin structure 2 is coated with an adhesive and heated as described above. The plates 3 and 4 may be welded separately one side at a time. Alternatively, as shown in FIG. 10, the resin structure 2 is disposed between the metal plates 3 and 4 and is made of metal for pressing up and down. A pressing force is applied by a roll (see FIG. 26), and the resin structure 2 is sandwiched between the heated metal plates 3 and 4 of the resin structure 2. The wall upright back surface portion 18 on the base back surface 10 side may be partially melted and welded.

The applied pressure is appropriately set according to the air pressure in the sealed space 6 that is planned by design. For example, the pressurization pressure by the metal roll for pressurization may be linear pressurization of about 35 to 50 kg per 1 m length. In addition to the linear pressurization method by line contact with a metal roll, planar pressurization for pressurizing the entire surface of the metal plate may be used. However, when the composite structure 1 is manufactured, linear pressurization with a metal roll is used. Pressure is more advantageous. For example, the air pressure in the sealed space 6 before welding is P (kg / mm ² ), the load per length l over the plurality of standing bodies 8 is W (kg / mm), and the sealed space 6 after welding. When the air pressure inside is P ′ (kg / mm ² ) and the total pressurization load per length l over the plurality of standing bodies 8 is W ′ (kg / mm), the increase in load is W '-W = (P'-P) l, and the increase in internal pressure in the sealed space 6 is (W'-W) / l.
It becomes.

  Since the resin structure 2 is not homogeneous throughout the heating temperature (° C.), the heating temperature is approximately within the range of the melting point of the resin (° C.) ± 10 ° C. This is performed by adjusting the contact time between the metal roll and the metal plates 3 and 4.

  The resin structure 2, various metal plates 3, 4, and various known adhesives are appropriately selected according to the design, and the composite structure 1 that exhibits desired performance is manufactured.

  As described above, the resin structure 2 may be welded to the metal plates 3 and 4 on both the front and back surfaces, but as shown in FIG. In the form in which the protrusions 14 having the top plate part 13 formed and forming a groove part having a convex or concave cross section are provided in the front-rear direction and the left-right direction, the base back surface 10 is a metal plate. 4, the composite structure 1 having a single-sided metal plate, which is composed of the resin structure 2 and one metal plate 4, can be provided. In such a composite structure 1 with a single-sided metal plate, the wall tip 9 on the top plate 13 side of the protrusion of the resin structure 2 is pressed against the heated metal plate 3 coated with an adhesive and melted and welded. By doing so, the composite structure 1 shown in FIGS. 14 to 15 can be manufactured. As shown in FIGS. 16-17, when the plate | board thickness dimension of the top plate part 13 which forms the protrusion 14 in the resin structure 2 is small, the form which the top plate part 13 swells with a metal plate in the cross-sectional arc shape. It is good also as a form which raised rigidity. Thus, when the top plate portion 13 has a form that bulges in an arc shape in cross section, the surface of the composite structure 1 bulges out in a zigzag shape or the like, so that the appearance can be improved and the design effect can be enhanced. .

  The composite structure 1 shown in FIGS. 14 to 15 is welded at a portion where the resin structure 2 that is in contact with the metal plates 3 and 4 via an adhesive is heated and pressurized to be melted. Since it can be surely welded, an adhesive such as an outer surface of the resin structure 2 that is not melted or a portion of the resin structure 2 that is not pressed by a metal roll for pressurization or the top plate portion 13 However, the portion that is merely in contact (or the outer surface of the top plate portion 13 may not be coated with an adhesive) may not be welded.

  11 and 13 show a composite structure 1 including a resin structure and a metal plate according to a fourth embodiment of the present invention. In this embodiment, as the metal plates 3 and 4, for example, metal plates 3 and 4 such as steel plates or stainless plates having a plate thickness of 0.01 mm to 2 mm are used. The body 2 is welded.

  When the plate thickness dimension of the first metal plate 3 and the second metal plate 4 is reduced as in the fourth embodiment, the first metal plate 3 and the second metal are caused by the expansion force of the air pressure in the sealed space 6. A bulge 11 is formed for each sealed space 6 of the upright body 8 so as to protrude outwardly from the inner side of the welded portion of the resin structure 2 of the plate 4. The bulge 11 on the second metal plate 4 side to which the wall tip end 9 side is welded is restrained by welding the periphery thereof rather than the bulge 11 on the second metal plate 4 to which the base back side is welded. Since the degree is small, the bulge 11 is large. As described above, even when the first metal plate 3 and the second metal plate 4 are partially bulged 11, the first metal plate 3 and the second metal plate 3 are welded by welding the resin structure 2. It welds in the state which ensured the freedom degree of the deformation | transformation by the fusion | melting of the junction part of the resin structure 2 at the time of welding with the metal plate 4. FIG. As described above, if the bulge 11 is formed on the inner side of the welded portion between the first metal plate 3 and the second metal plate 4 by the expansion force due to the air pressure of the sealed space 6 portion, the initial tension is generated by the air pressure. When force is applied, when bending force is applied and compressive force is applied, deformation does not occur until the initial tensile force disappears, so buckling can be suppressed and rigidity can be increased as a result. At the same time, the plurality of bulges 11 produce an aesthetic appearance and improve the design.

  Since the bulge 11 is formed for each sealed space 6 of the standing body, the bulge 11 formed for each sealed space 6 of the standing body 8 always applies a tensile force to the metal plate in that portion. 21 (a), the composite structure 1 has the bulge 11 as shown in FIG. 21 (b) as compared to the case without the bulge 11 as shown in FIG. 21 (a). As the distance from the neutral axis X in the plate thickness direction increases, the cross-sectional secondary moment around the in-plane direction X-axis increases, so that the rigidity can be improved. In general, the composite structure 1 is often used under atmospheric pressure or in a pressurized atmosphere. Therefore, the air pressure in the sealed space 6 may be in a state exceeding 1 atm. A tensile force can be applied to the entire portion of the bulge 11, and accordingly, the rigidity of the bulge portion can be increased, and local buckling of the bulge portion can be prevented.

Further description will be given with reference to FIGS. Consider the case where it is assumed that the resin structure 2 is welded to the metal plates 3 and 4 so that the positions of the first metal plate 3 and the second metal plate 4 do not change.
