The present invention relates to a composite structure comprising a resin structure and a metal plate used in a building member such as a wall material, a flooring material, or a roofing material, and a method of manufacturing the same.

Heretofore, a technique has been known in which a cap sheet made of a synthetic resin having a plurality of caps is bonded to a synthetic resin on the bottom side of the shroud by an adhesive. A back sheet and a liner sheet made of a synthetic resin bonded to the top side of the shield are laminated as a sheet made of a polypropylene resin as a main material to produce a plastic bubble sheet ( For example, refer to Patent Document 1).

Further, for example, a technique for a panel for a building in which a calcium carbonate foamed plate is bonded to an inner surface of both sides of an inorganic plate-shaped core formed into a concave-convex shape by an epoxy-based adhesive is known. The steel sheet (panel) is bonded to the outside via an epoxy-based adhesive (for example, see Patent Document 2).

In the previous case, since the plate core is only followed by the adhesive, it becomes the slab core and the adhesive and the adhesive and the synthetic resin back cover or the liner or the calcium carbonate foam. The increase in the area of the back surface is not produced before and after, but depends on the bonding strength of the adhesive. Therefore, the bonding area of the plate-shaped core is increased in advance and the subsequent step is performed. In the case of synthesizing a resin-containing resin structure having a vertical body and a metal plate by such a subsequent method, the optimum adhesives are different depending on the materials of the respective materials, and thus the adhesive monomer is different. It is difficult to obtain a higher bond. In addition, since the resin structure is in the form of a columnar body, which is different from the planar shape, the subsequent area is small, and sufficient adhesion is not obtained, so that it is easily peeled off, and thus it is not practical to be used as a composite plate. Further, when a bending force acts on the panel, for example, a compressive force acts on the panel on one side, and a tensile force acts on the panel on the opposite side. In this case, it is also necessary to pass the adhesive (layer). The stress is transmitted, so a strong joint is expected.

(1) By heating a metal roll that is in contact with the first metal plate 3 or the second metal plate 4, the shape of the succeeding surface of the resin structure 2 is melted by the heated metal plate.

(2) The heating furnace 23 may be a hot air heating furnace that heats a metal plate by spraying hot air, and the metal structure is heated by the resin structure together with the metal plate, and is pressed by the heating furnace. The heated metal plate was attached to the side of the adhesive-coated side, and the metal roll was used as a pressure roll.

(3) The heating furnace 23 may be a heating furnace that heats a metal plate by high-frequency induction heating, and heats the metal plate by passing the resin structure together with the metal plate through the high-frequency induction heating device. The metal roll was used as a heating and pressurizing roll by crimping the heated metal plate to melt the adhesive coated side.

Further, the first metal plate 3, the second metal plate 4, and the resin structure 2 may be formed as short strips instead of the continuous first metal plate 3, the second metal plate 4, and the resin structure 2. A specific final product size such as a rectangle or a rectangle is crimped to the heated metal plate (first metal plate 3 and second gold) The plate 4) is bonded to the side of the back surface of the resin structure 2, and is bonded together with the metal plate from the outside. Further, as the mechanism for pressing the metal plate, a metal roll may be used. For example, a hot press that pressurizes from the outside by a high-temperature plate member or an autoclave that is pressurized with high-pressure steam may be used. , or pressurized chambers, etc.

In the case of the resin structure in which the single surface of the resin structure 2 is welded to the metal plate via the adhesive 5, or the front and back surfaces of the resin structure 2 are welded to the metal plate via the adhesive 5 The form will be specifically described.

One of the resin structure 2 and the first metal plate 3 shown in Fig. 1 (a) and Fig. 3 (a) is welded to the metal plate 3 in the following state, that is, as shown in Figs. 4(a) and 12(b). In the manufacturing step, the first metal plate 3 coated with the adhesive 5 as the adhesive layer on the inner upper surface is heated by passing through the heating furnace 23, or by being attached thereto. The heating furnace 23 is heated to contact the metal roll 17 on the upper side to be heated, and is heated at least to the melting point of the resin structure 2. As the heating mechanism of the first metal plate 3, the coated surface coated with the adhesive 5 can be set as the lower surface, and the upper surface of the first metal plate 3 can be heated to be higher than the resin structure 2 The metal roll 17 on the upper side of the melting point is pressurized (or, in the case of manufacturing the composite structure of the short strip, as shown in Fig. 26(b), placed on the heating contact plate 16 in the contact heater The first metal plate 3 is heated to at least the melting point of the resin structure 2 at a specific time. Since the heating temperature of the metal plate such as the first metal plate 3 is not uniform throughout the entire material of the resin structure 2, it is partially melted at a temperature lower than the assumed melting point, and thus is set substantially at the melting point of the resin structure 2. (°C) within ±10 °C. For example, when the resin forming the resin structure 2 is an olefin resin and the melting point thereof is 170 ° C, it is set in the range of 160 ° C to 180 ° C, for example, about 170 ° C. The temperature (°C) of the above-mentioned metal roll 17 (or the heating contact plate 16) also depends on the manufacturing method, for example, it is set to be slightly higher than the above temperature of 170 °C.

Further, after the side of the vertical body 8 of the resin structure 2 is brought into contact with the adhesive application surface of the heated first metal plate 3, the pressing force is appropriately applied by the metal roll 17 for pressurization, and by The metal roller 17 is rotationally driven by the driving device (not shown) (rolling in the form of heating the contact plate 16 in FIG. 26(b)), thereby pressurizing from the outside of the resin structure 2, and adding from the outside. The first metal plate 3 between the metal rolls 17 (or the heating contact plate 16) and the resin structure 2 are pressed. At this time, the wall end portion 9 of the cylindrical body 8 in the resin structure 2 is pressure-bonded to the first metal plate 3 via the adhesive, and the wall of the first metal plate 3 is heated. The front end portion 9 is heated to a melting point or higher and melted, and the front end portion 9 of the wall portion is crushed by pressurization to form a widened wall portion 7a, and the front end portion 9 of the wall portion is formed in a state where the welded area is increased. The adhesive 5 and the first metal plate 3 are in close contact with each other to weld the resin structure 2 to the first metal plate 3. In the above case, the base surface 15 on the side of the body 8 of the base portion 12 in the resin structure 2 is not melted by the heat of the first metal plate 3.

In the above case, the pressing time of the metal roll 17 after the resin structure 2 is in contact with the metal plate 3 (4) and the thickness of the adhesive 5 are set according to the design. Although the thickness of the metal plate 3 (4) and the adhesive are also used, the thickness of the adhesive 5 is set to, for example, a range of 3 to 20 μm, and the pressurization time is set to about 0.05 second to 1 second. Composite structure after welding 1 is cooled by the cooling unit 26 (see FIG. 12) so as to be equal to or lower than the melting point of the resin structure 2 within 1 second. As the cooling unit 26, for example, a blower or a mist cooler that cools the composite structure 1 by blowing air can be cited.

The composite structure 1 of the second embodiment shown in FIG. 5 to FIG. 7 is a form in which the base back surface 10 side of the resin structure 2 is welded to the second metal plate 4. It is a form in which only the resin structure 2 in FIG. 4 is inverted upside down and welded. In this embodiment, the adhesive agent 5 is applied to the base back surface 10 of the resin structure 2 to provide an adhesive layer, and the base back surface 10 of the resin structure 2 is brought into contact with the adhesive coating of the heated second metal plate 4. Cloth. Then, the second metal plate 4 and the resin structure 2 are pressurized from the outside at, for example, 40 kg/m, and the wall of the base back surface 10 of the resin structure 2 is raised and the back surface portion 18 is crimped via the adhesive 5 In the second metal plate 4, the back surface portion 18 is raised by the heat of the second metal plate 4, and the back surface portion 18, the adhesive agent 5, and the second metal plate 4 are adhered to each other to bond the resin structure. The body 2 is welded to the second metal plate 4. In this case, the upright 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 back surface portion 18 is a portion on the back side of the base portion 10, that is, the base portion on the base end side of the vertical body 8, and is thermally fused by the second metal plate 4 on the side of the base back surface 10 of the resin structure 2 In the case of being welded and welded, the portion which is extended toward the back surface side of the base portion by the pressure and heat is particularly melted, and the portion on the base end side of the vertical body 8 which is close to the back surface side of the base portion is formed to be oriented. The widened wall portion 7a on the side of the metal plate and having a gradually increasing width increases the area welded by the pressurization. Therefore, the back side 10 of the base of the resin structure 2 having the body 8 is sure The ground welding improves the joint strength as compared with the case where it is not melted. The base back surface 10 other than the widened wall portion 7a may be welded, but the pressing force is transmitted to the back surface of the base via the vertical body 8. Therefore, the back surface portion 18 is raised by the welded wall to obtain a firm adhesive force.

The opposite side of the unprovided metal plate 3 (4) is welded to the other metal plate 4 (3) via the adhesive 5, whereby the front end portions 9 of the respective wall portions in the resin structure 2 are passed through the adhesive 5 The metal structure 3 is welded to the metal plate 3, and the back surface portion 18 of the base back surface 10 of the resin structure 2 is welded to the metal plate 4 via the adhesive 5 to produce the composite structure 1.

More specifically, after the continuous composite structure 1 having the metal plate 3 (4) on one side of the resin structure 2 as shown in FIG. 4 is produced, the adhesive 5 is applied by heating. A continuous metal plate 4 (3) is pressed and welded from the outside to produce a composite structure 1 which is welded to each other by coating the both sides of the resin structure 2 with a metal plate.

Alternatively, after the composite structural body 1 having the short strip of the metal plate 3 (4) on one side of the resin structural body 2 is produced, the composite structural body 1 is reversed and heated in contact with the heater. The plate 16 is placed with a metal plate 4 (3) on the upper surface of which the other strip of the adhesive 5 is applied, and the resin structure 2 in the composite structure 1 is welded to the other metal plate 4 (3). A continuous composite structure 1 welded in such a manner that the metal sheets are coated on both sides of the resin structure 2 is produced.

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 whose surface is plated may be used. As the metal plates 3 and 4, a continuous or short strip of plate or sheet metal plate can also be used. The thickness of the metal plates 3 and 4 is appropriately set according to the design depending on the place where the floor portion of the building portion or the roofing material is used.

It is preferable that the metal sheets 3 and 4 are appropriately subjected to a substrate treatment before the application of the adhesive. Use an adhesive that is activated by heat, and live as heat As the adhesive, for example, an epoxy-based adhesive, a polyester-based adhesive, an urethane-based adhesive, or the like may be used.

Next, various aspects of the resin structure 2 used in the composite structure 1 of the present invention will be described with reference to Fig. 1 . In the case of carrying out the present invention, the resin structure 2 may be in the form of a continuous form or a short strip, and for example, an olefin-based resin such as a polypropylene resin or a polyethylene resin, or another synthetic resin may be used. The thickness of the resin structure 2 is set according to an appropriate design according to the place where the floor part of the building part or the roofing material is used.

The resin structure 2 includes, for example, a flat base portion 12 as shown in Figs. 18 (a), (b), and (c) to Figs. 19 (a), (b), and (c), and is integrally provided with the base portion. The wall portion 7 on which the surface of the 12 is raised. When the wall portion 7 is formed into a tubular shape, the cylindrical body 8 is formed in a plurality of spaces in the front-rear direction and the left-right direction by the wall portion 7, or as shown in Fig. 20 (a) As shown in (b) and (c), a plurality of them are formed in a continuous manner in the front-rear direction and the left-right direction.

More specifically, referring to the respective drawings, in the form shown in FIGS. 18(a), (b), and (c), the body is integrally formed from the surface of the plate-like base portion 12 in a cylindrical shape. The cylindrical body 8 having the wall portion 7 having the circumferential side wall having a circular cross section or the like is formed in a zigzag manner in the front-back direction (member length direction) and the left-right direction (member width direction) of the plate-like base portion 12 at intervals. In addition, a through hole is formed in the flat plate portion of the base portion 12 concentrically with the above-described vertical body 8, and the cylindrical body 8 is formed as a cylindrical portion penetrating the base portion. In the above-described embodiment, the arrangement of the above-described uprights 8 is equally spaced at an angle around the center of the vertical body 8 (in the illustrated form, an angular interval of 60°) Ground setting. The wall portion 7 has a plate thickness smaller than that of the base portion 12, and is formed to gradually decrease in wall thickness toward the front end portion 9 of the wall portion.

In the resin structure 2 shown in Figs. 19(a), (b), and (c), the portions different from the above-described forms shown in Figs. 18(a), (b), and (c) are as follows. Unlike the top plate portion 13 which is connected to the front end portion 9 of the wall portion 7 of the wall portion 7, the front end portion of the wall portion of the wall portion 7 is blocked by the top plate portion 13, and the vertical body 8 including the top plate portion 13 is entirely protected. A cover-like projection 14. In the embodiment shown in Figs. 19 (a), (b), and (c), the top plate portion 13 integrally formed from the front end portion 9 of the wall portion 7 is formed by the peripheral side wall of the self-standing body 8. The wall front end portion 9 of the entire circumference forms the top plate portion 13, and a plurality of shroud-like projections 14 projecting from the base surface into a hollow shape are formed. The thickness of the top plate portion 13 is smaller than the thickness of the wall portion 7.

In the resin structure 2 shown in FIGS. 20(a), (b), and (c), the resin structure 2 is formed such that the wall portion 7 is continuous in the front-rear direction so as to rise from the base portion 12. The wall portion 7 in the front-rear direction and the wall portion 7 in the left-right direction in the member width direction are formed at intervals and intersect at right angles, thereby forming a continuous standing side wall with the adjacent vertical body 8 Shape 8.

As described above, when the vertical body 8 in the resin structure 2 is a cylindrical body 8 that penetrates the front and back sides of the resin structure 2, the back surface of the resin structure 2 can be The both surfaces are welded to the metal plates 3 and 4, respectively, and a sealed space 6 is formed in which the respective vertical bodies 8 and the metal plates 3 and 4 of the front and back are pressed together. Further, as in the embodiment described below, the wall portion of the cylindrical body 8 is blocked by the top plate portion 13 on the side of the front end portion 9, and the wall on the back side 10 side of the base portion is pressurized and melted. When the back surface portion 18 is raised and welded to the metal plate, the sealed space 6 pressurized by the inside of the cylindrical body 8 can be formed.

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

8 to 10 show a composite structure 1 including a resin structure and a metal plate according to a third embodiment of the present invention produced by the above-described method, and Fig. 8(a) includes a resin structure and a metal. The longitudinal cross-sectional front view of the composite structural body 1 of the panel, (b) is a longitudinal cross-sectional front view showing the E portion of (a), and FIG. 9 is a perspective view of the composite structural body 1 including the resin structural body and the metal plate. 10(a) is a longitudinal cross-sectional front view showing a state in which the resin structure of the third embodiment of the invention is welded and bonded to the metal plate, and (b) is a longitudinal section showing the F portion (a). front view.

In the composite structure 1 of the third embodiment, the resin structure 2 including the plurality of vertical bodies 8 based on the wall portion 7 rising from the base surface 15 of the base portion 12 is disposed at the center portion in the thickness direction. And the front and back sides of the resin structure 2 are welded to the first metal plate 3 by the portion of the adhesive 5 formed on the adhesive layer of the first metal plate 3 and the second metal plate 4 which are heated. The two metal plates 4 are integrated.

In the present invention, the resin structure 2 can be welded to at least one metal plate via the adhesive 5 by the structure of the resin structure 2, whereby the resin structure 2 and the metal plate are formed together. The pressure is a sealed space 6 in a state where the air pressure exceeds 1 air pressure. In the third embodiment, the front end portion 9 of the cylindrical body 8 of the cylindrical body 8 which is raised by the wall portion 7 which rises from the base surface 15 (see FIG. 10) of the resin structure 2 is used. With resin knot The base back surface 10 of the structure 2 is sandwiched and welded by the first metal plate 3 and the second metal plate 4, and the inside of the cylindrical body 8 is defined as a sealed space 6. When it is assumed that the air pressure in the sealed space 6 is normally used under atmospheric pressure, the internal pressure based on the air pressure in the sealed space 6 is increased by making it higher than the atmospheric pressure of one air pressure, thereby including the surrounding enclosed space. The vertical body 8 of the wall portion 7 and the first metal plate 3 and the second metal plate 4 are preliminarily introduced with the initial tensile stress. Thereby, when the bending force acts in the out-of-plane direction, deformation does not occur until the initial tensile stress is canceled, and as a result, the rigidity is increased, and bending or partial bending is not caused as much as possible. The setting is made such that the internal pressure based on the air pressure in the air in the sealed space 6 is increased as compared with the air pressure in the place to be used. The air pressure in the sealed space 6 is set to, for example, one air pressure (101325 Pa = 760 mmHg (Torr)) < air pressure in the sealed space 6 ≦ 1.1 air pressure to 2.0 air pressure. Further, the air pressure in the air in the sealed space 6 is welded by pressurization, and is cooled to, for example, within 1 second by the cooling portion 26 such as a blower or a mist cooler to a melting point (° C.) of -15 ° C of the resin. The shrinkage of the resin structure 2 and the metal plate 3 (4) (the thermal expansion coefficient of the resin structure 2 is larger than that of the metal plate), the vertical body 8 of the resin structure 2 is also smaller, thereby improving the sealed space 6. The welding is surely performed under the pressure. The gas pressure in the sealed space 6 can be adjusted in accordance with the change in the height of the melting of the resin structure 2 accompanying the pressing force and the pressurization.

In the present invention, when the resin structural body 2 is welded to the metal plate, the portion of the resin structural body 2 to be pressure-welded and joined, for example, by the heat of the heated metal plate, and the resin structural body 2 or The height dimension of the vertical direction of the vertical body 8 in the resin structure 2 (the height dimension of the wall portion 7) is higher than that of heating. The state before the pressure is small, and it is preferable to form a resin structure in which the height dimension in the axial direction of the vertical body 8 is increased to the extent that the height dimension of the resin structure 2 or the wall portion 7 is reduced. 2. By raising the air pressure of the air in the sealed space 6 in this manner and completing the welding in this state, the vertical body 8 surrounding the sealed space 6 and the first metal plate 3 and the second metal plate 4 can be advanced in advance. Introduce the initial tensile stress. Moreover, it is advantageous in that the air pressure in the air 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 the same can be manufactured at low cost. When the metal plate is a thin plate, the protrusion 11 (see FIGS. 11 and 12) in which the metal plate protrudes in the out-of-plane direction by the expansion force of the air in the sealed space 6 can be formed, and is bent in the out-of-plane direction. When the force acts on the above-mentioned projection 11, the composite structural body 1 which is improved in rigidity so as not to be locally bent or bent can be obtained. Further, by increasing the gas pressure in the sealed space with respect to one gas pressure, the resonance frequency of the metal plate bonded to the back surface or the front and back of the resin structure 2 becomes high, and it is used in a region where the frequency is low. When it is not easy to resonate, the rigidity of the composite structure as a whole is improved by the rigidity.

The form of the composite structural body 1 can be manufactured continuously or intermittently. For example, in the case of continuous production, a composite structure in which both sides of the resin structural body 2 are welded to the metal plate via an adhesive is manufactured. In the case of the first embodiment, when the single-sided surface of the resin structure 2 is welded to the composite structure 1 of the metal plate via the adhesive, it is produced by the manufacturing method shown in Fig. 12 (a). It can be manufactured by the form shown in FIG. 12(b). Further, in the case of intermittent production, although illustration is omitted, one or both sides of the resin structure 2 of a specific length of a short strip may be melted via an adhesive. The composite structural body 1 is manufactured by joining a metal plate of a specific length of the short strip.

As described above, in the present invention, depending on the air pressure in the sealed space 6 in the vertical body 8, and depending on the thickness of the metal plate, the metal plates 3, 4 are not convex and protruded into a circular cross section. The case of an arc or the like. For example, in the case where the thick plate is formed so as not to be deformed, the state in which the tensile force acts on the portions of the metal plates 3 and 4 which are part of the sealed space 6 by the air pressure in the sealed space 6 is used. Further, in the case of a metal plate which is a sheet-like thin plate, it is formed to form a projection 11 which is convex in a circular arc shape by air pressure (see FIGS. 11 and 12), and the tensile force acts on The state of the air pressure and the convex portion of the cross section. As described above, when a bending force is applied by forming the projections 11 by the metal plates 3, 4 of the thin plate, as shown in Fig. 21, the distance (r') of the portion of the projection 11 from the neutral axis X is In the case where the protrusion 11 is not provided, the distance (r) is higher in proportion to the power of the distance of 3, which is advantageous, and the expansion force based on the air pressure in the sealed space 6 further functions, the protrusion 11 Since the initial tensile force acts in part, even if the compressive force based on the bending force acts, it is advantageous in that the initial tensile force does not deform before being canceled by the compressive force.

8 to 10 is a form in which the wall portion front end portion 9 side or the base portion rear surface side 10 (particularly a pressurized portion) of the vertical body 8 of the resin structure 2 of the embodiment shown in Fig. 18 is obtained. The first metal plate 3 or the second metal plate 4 which is coated with the adhesive 5 and heated by the adhesive agent 5 at the front end portion 9 side or the base back surface 10 side of the vertical body 8 of the resin structure 2 is simultaneously Clamped and welded in a pressurized manner. Alternatively, the wall portion front end portion 9 side or the base portion back surface side (particularly the pressurized portion) of the upright body 8 of the resin structure 2 is abutted side by side. Disposed on the first metal plate 3 or the second metal plate 4 coated on the heating contact plate 16 in the contact heater for heating and coated with the adhesive 5 and heated, and used for the self-resin structure The pressed metal roll is pressed by the upper side of the second, and is pressed by the heating contact plate 16 and the metal roll for pressurization, thereby being melted and welded by the adhesive 5 .

8 to 10, the wall portion front end portion 9 side and the base portion rear surface side 10 (particularly the pressurized portion) of the vertical body 8 of the resin structure 2 of the embodiment shown in Fig. 18; And being sandwiched by the first metal plate 3 or the second metal plate 4 coated with the adhesive 5 and heated by the heating furnace 23, and by the first metal plate 3 and the second metal plate 4 The outer side is sandwiched and pressurized (or heated and pressurized) by a metal roll 17 that is rotationally driven by a driving device (not shown), and the vertical body of the resin structure 2 is thermally melted by the metal plates 3 and 4. The wall portion end portion 9 side and the base portion back surface 10 side of the wall portion 8 are welded by the adhesive 5 . Though not shown in the drawings, the side of the wall portion front end portion 9 side or the base portion back surface 10 side of the vertical body 8 of the resin structure 2 may be welded to the metal plate at the same time, and the columnar body of the resin structure 2 may be used. The wall portion end portion 9 side or the base portion back surface 10 side of the wall portion 8 is welded side by side to each of the heated first metal plate 3 or the second metal plate 4 coated with the adhesive 5 side by side. When the resin structure 2 is welded side by side, the surface of the resin structure 2 which is not disposed and which is not welded to the metal sheet does not need to be melted, so that it is not necessary to heat the metal roll 17 which is in direct contact with the resin structure 2.

The wall portion front end portion 9 and the base portion back surface 10 (particularly the base portion back surface side of the wall portion 7) in the resin structure 2 are heated and melted by the heated metal sheets 3, 4, and are Pressurizing with a metal roll for pressurization The molten portion is crushed to form a widened wall portion 7a, and the area of the welded portion is increased while being welded. Therefore, the fusion of the resin structure 2 and the metal plates 3 and 4 can be firmly welded. Further, since the melting of the heat conduction from the heated metal sheets 3 and 4 to the resin structure 2 is gradually performed, the widened wall portion 7a is gradually increased in size toward the portion where the wall portion is welded. It is formed, and therefore, it becomes a firm and firm fusion.

Further, the widened wall portion 7a is formed such that the thickness of the wall portion gradually increases toward the portion to be welded, and the stress transfer from the resin structure 2 to the respective metal plates 3, 4 can be smoothly performed. Or the transfer of stress from the metal plates 3, 4 to the resin structure 2. Further, in the welded portion of the metal plates 3, 4 and the resin structure 2, since the distance between the walls of the vertical body 8 becomes small, the span of the metal plate portion between the walls is also small. The rigidity of the metal plate in the portion can be increased, and the deformation when the bending force acts can be reduced.

In the case of producing the composite structure 1 of the resin structure 2 and the metal sheets 3 and 4 such as a steel sheet as described above, as described above, the resin structure 2 may be separately welded to the surface and coated with the adhesive. The heated metal plates 3 and 4 or, as shown in Fig. 10, may be provided with a resin structure 2 between the metal plates 3 and 4, and a metal roll for pressurizing up and down (refer to Fig. 26). And the pressing force acts to sandwich the resin structure 2, and the wall front end portion 9 and the base back surface 10 side of the resin structure 2 are heated by the heated metal plates 3, 4 of the resin structure 2. The wall rises and the back portion 18 is partially melted and welded.

In the case of producing the composite structure 1 of the resin structure 2 and the metal sheets 3 and 4 such as a steel sheet as described above, as shown in FIG. 10, an adhesive is applied thereto. The resin structure 2 is placed between the heated metal plates 3 and 4, and a pressing force (not shown) acts to apply a pressing force to sandwich the resin structure 2, and the resin structure 2 is used. The wall portion front end portion 9 and the base portion back surface 10 side portion of the resin structure 2 are melted by the heated metal sheets 3 and 4, whereby the adhesive is welded to the resin structure 2, and the molten adhesive is welded to The metal plates 3 and 4 are cooled by a blower or a mist cooler, etc., whereby the shrinkage of the resin structure 2 and the metal plate 3 (4) (the coefficient of thermal expansion of the resin structure 2 is larger than that of the metal plate) is also present. Therefore, the welding is surely performed while further increasing the pressure in the sealed space 6.

The above-described pressing force is appropriately set in accordance with the air pressure in the sealed space 6 which is predetermined by design. For example, the pressurization pressure of the metal roll for pressurization may be based on a linear pressure of about 1 m per unit length and 35 to 50 kg. In addition to the linear pressing method based on the line contact of the metal roll, the surface of the pressed metal sheet may be pressurized, but in the case of producing the composite structure 1, it is based on the line of the metal roll. Pressurization is more advantageous. For example, the air pressure in the sealed space 6 before welding is set to P (kg/mm ² ), and the load per unit length l of the plurality of vertical bodies 8 is set to W (kg/mm), and after welding, When the air pressure in the sealed space 6 is P' (kg/mm ² ), and the total load per unit length l of the plurality of vertical bodies 8 is set to W' (kg/mm), the load is increased. The amount becomes W'-W=(P'-P)l, and the internal pressure in the sealed space 6 increases to (W'-W)/l.

The heating temperature (° C.) is not uniform in the whole of the resin structure 2, and therefore, the metal roll and the metal plate for heating are appropriately adjusted in consideration of the temperature in the factory in the range of the melting point (° C.) ±10° C. of the resin. 3, 4 contact time, etc. get on.

The above-described resin structure 2, various metal plates 3 and 4, and various known adhesives are appropriately selected according to the design, and the composite structural body 1 exhibiting desired properties is produced.

As described above, the metal sheets 3 and 4 on the front and back surfaces of the resin structure 2 may be welded to each other. However, as shown in FIG. 22, the resin structure 2 has the following aspects at intervals in the front-rear direction and the left-right direction. In the form of the projections 14, the projections 14 have a top plate portion 13 integrally provided from the front end portion 9 of the wall portion and are formed with a groove portion having a convex or concave shape, by welding the base back surface 10 to the metal plate 4 It is also possible to form the composite structure 1 including the single-sided metal plate of the resin structure 2 and the one metal plate 4. The front end portion 9 of the wall portion on the top plate portion 13 side of the protrusion of the resin structure 2 in the composite structure 1 of the single-sided metal plate is pressed against the metal plate 3 coated with the adhesive and heated. The composite structure 1 shown in Figs. 14 to 15 can be produced by melting and welding. As shown in FIG. 16 to FIG. 17, when the thickness of the top plate portion 13 in which the protrusions 14 are formed in the resin structure 2 is small, the top plate portion 13 may be formed together with the metal plate. It protrudes into a circular arc shape and increases rigidity. In this manner, when the top plate portion 13 is convexly formed in a circular arc shape, the surface of the composite structural body 1 is convexly formed in a zigzag shape or the like, and the appearance can be improved and the new style effect can be improved.

The composite structure 1 shown in Figs. 14 to 15 can be welded by being melted by heating and pressurizing the resin structure 2 which is in contact with the metal sheets 3 and 4 via the adhesive, and is surely welded, so that it is not melted. a part of the resin structure 2 or a resin structure 2 which is not pressurized by a metal roll for pressurization or The outer surface of the top plate portion 13 or the like is only in contact with the portion of the adhesive (or the outer surface of the top plate portion 13 may not be coated with an adhesive) or may be welded.

Fig. 11 and Fig. 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, metal plates 3 and 4 such as steel plates or stainless steel plates having a thickness of, for example, 0.01 mm to 2 mm are used, and the resin structures 2 are welded to the metal plates 3 and 4.

As in the fourth embodiment, when the thickness of the first metal plate 3 and the second metal plate 4 is reduced, the first metal plate 3 and the second metal plate 4 are caused by the expansion force of the air pressure in the sealed space 6. The projections 11 projecting convexly outward from the inner side of the welded portion of the resin structure 2 are formed for the sealed space 6 of each of the vertical bodies 8. The projection 11 on the side of the second metal plate 4 on the side of the front end portion 9 of the wall portion is welded to the projection 11 of the second metal plate 4 on the back side of the base portion, and the degree of restraint is small. Therefore, the projection 11 becomes large. As described above, even when the first metal plate 3 and the second metal plate 4 are partially formed with the protrusions 11, by welding the resin structure 2, it is also ensured that the first metal plate 3 and the second metal plate 4 are The welding is performed in a state in which the degree of freedom of deformation of the joint portion of the resin structure 2 at the time of fusion is melted. As described above, if the inner portion of the welded portion of the first metal plate 3 and the second metal plate 4 is formed by the expansion force of the air pressure based on the portion of the sealed space 6, the initial stretch is performed by the air pressure. When the force acts, and the bending force acts to receive the compressive force, the deformation does not occur before the initial tensile force disappears, so that the bending is suppressed, and as a result, the rigidity can be improved and the plurality of protrusions 11 can be aesthetically pleasing. The new style is improved.

Since the projections 11 are formed for the sealed space 6 of each of the vertical bodies, the projections 11 formed by the sealed space 6 of each of the vertical bodies 8 cause the tensile force to act on the same. As shown in Fig. 21 (a), as shown in Fig. 21 (a), as shown in Fig. 21 (b), the in-plane direction is obtained by having the above-mentioned projections 11 The increase in the secondary moment around the X-axis is equivalent to the distance from the vertical axis X in the direction of the thickness of the composite structure 1, so that the rigidity can be improved. The composite structure 1 is usually disposed in an atmospheric pressure or in a pressurized environment, and is used in a state in which the gas pressure in the sealed space 6 exceeds 1 gas pressure, and the initial stretching can be performed by internal pressure. The force acts on the entire portion of the above-mentioned projection 11, so that the rigidity of the convex portion can be correspondingly increased, and partial bending or the like of the convex portion can be prevented.

This will be further described with reference to Figs. 21(a) and (b). The case where the resin structure 2 is welded to each of the metal plates 3 and 4 in such a manner that the positions of the first metal plate 3 and the second metal plate 4 are not changed is considered. As shown in Fig. 21 (a), the distance from the X-axis in the in-plane direction to the center of gravity G of the portion (the portion where the hatching is performed) of the metal plates 3 and 4 corresponding to the sealed space 6 is set to r, The thickness of the metal plates 3 and 4 is set to t, the length of the portion that protrudes into a spherical shape is set to 1, the amount of increase in the height in the out-of-plane direction is Δh, and the portion is convexly formed in a spherical shape. When the angle is 11 and deformed, the distance from the X-axis to the center of gravity G is set to r', and the second moment of the section around the X-axis of the form shown in Fig. 21(a) is set to I, which is partially deformed. The second moment of the section of the spherical portion 11 is set to I'. If, for example, l=10 (mm), t=1 (mm), r=5 (mm), and Δh=1 (mm), r'=5.672 (mm), and I'=323.4 (mm ⁴ ), I=250.8 (mm ⁴ ). That is, the increase amount (I'-I) of the second moment of the profile becomes I'-I = 72.6 (mm ⁴ ), and the rigidity can be improved.

The metal plate 3 is welded to the thin plate via the adhesive, and in the form in which the metal plate 3 on the back side is provided with the protrusion 11 protruding outward, the top plate of the protrusion 14 including the vertical body 8 can also be formed. The composite structure 1 in the form of a projection 11 that protrudes outward from the portion 13. According to the composite structure 1 of the form shown in FIG. 22 and FIG. 23, the protrusion 14 side is heated and melted by the heat of the metal plate in the second metal plate 4, and is heated and welded via the adhesive 5 on the metal plate 4 side. This makes it possible to produce the composite structure 1 in the form shown in Figs. 11 and 13 .

In the resin structure 2 of the embodiment shown in FIG. 20, the adjacent vertical bodies 8 are continuous with each other in the front-rear direction and the left-right direction by the partial body portion 7 in which the wall portions 7 are common. When the resin structure 2 is welded to the metal plate, it can be continuously landed at a small interval in the front-rear direction and the left-right direction. In a confined space 6.

As in each of the above embodiments, the resin structure 2 has a portion which is melted by the heated metal plate 3 (4) via the adhesive 5, and is not melted by the heated metal plate 3 (4).

In the case where the resin structure 2 is welded to the metal plate 3 (4) via the adhesive 5 as in the above embodiments, the base portion of the base portion 12 and the intermediate portion of the wall portion of the vertical body 8 are not In the manner of melting, if the front end portion 9 of the welded wall portion or the wall of the base back surface 10 rises the back portion 18, either or both of the welded wall portion front end portion 9 or the base portion back surface 10 can be formed as the back portion 18. The composite structural body 1 which is melted and welded to the metal plate can be formed by being welded to the composite structural body 1 of the metal plate without lowering the rigidity of the resin structural body 2 as a whole.

Since the composite structure 1 manufactured as described in each of the above embodiments includes the resin structure 2 and the metal plate 3 (4), it exhibits high rigidity and is lightweight, and can be manufactured at a lower cost. Further, the composite structural body 1 can also suppress vibration or heat conduction, and can be used, for example, for people's livelihood or construction.
