Description

  The present invention relates to a structure of a foamed resin laminated metal plate in which a foamed resin layer is disposed by sandwiching a thermoplastic resin foam material between a pair of opposing metal plates.

  A composite panel in which a foamed resin layer is placed with a pair of metal plates made of aluminum facing each other and a thermoplastic resin foam material such as PP or PE sandwiched between them, is lightweight but has excellent strength and heat resistance. A composite panel molded body obtained by molding the material into a desired shape is widely used as a building member, a machine member, or the like.

  When mounting such a composite panel molded body on a member to be fixed, a through-hole penetrating in the thickness direction of the molded body is provided like a general panel molded body, and between the member to be fixed. Even if bolting is attempted, since the thermoplastic resin foam is a soft material, the metal plate bends at the tightening portion, and sufficient tightening axial force cannot be obtained. Then, after removing the thermoplastic resin foam material in the tightening axis direction, a technique for fixing the panel molded body on the fixed member by bolting between one of the pair of metal plates and the fixed member. Has been developed.

  For example, Patent Document 1 discloses a fixing structure of a composite panel molded body in which a countersink hole is provided so as to remove resin, and bolting is performed between one of a pair of metal plates and a fixed member. ing. In the technique shown in Patent Document 1, a through hole that penetrates a pair of metal plates of a composite panel is provided, and a counterbore hole that reaches a thermoplastic resin from one of the pair of metal plates is provided to remove the resin, and the seat A bolt is inserted into the through-hole from the through hole, and the other member of the pair of metal plates and the fixed member are bolted.

  Patent Document 2 discloses a fixing structure of a composite panel molded body using a fastener. In the technique shown in Patent Document 2, a tubular fastener having a through hole penetrating a pair of metal plates of a composite panel and having a flange at an end from one front side of the pair of metal plates is provided in the through hole. insert. When the flange at one end is in contact with the front side of the metal plate and the fastener is compressed in the axial direction from the other end, the shaft near the flange is plastically deformed so as to expand in the radial direction. The fastener and the metal plate are fixed so that the plate is sandwiched between the flange and the plastic deformation portion. The composite panel molded body can be fixed on the fixed member via the fastener by further fixing the fastener to the fixed member with a bolt or the like.

  Patent Document 3 discloses a fixing structure of a composite panel molded body using a fastener (a fastening portion provided on a member to be fixed as a fastener). In the technique shown in Patent Document 3, both the pair of metal plates and the fasteners (bolts and nuts) 8 are fixed. In detail, while providing the through-hole which penetrates a pair of metal plate of a composite panel, the tubular fastener which has a collar part in an end part from one front side of a pair of metal plates is inserted in this through-hole. In a state where the collar portion is in contact with the front side of the metal plate, a bolt is inserted from the collar portion side into the tubular fastener and the nut is tightened. As a result, a flange is also formed at the end of the fastener opposite to the collar. Further, when the nut is tightened, the barrel portion of the fastener is plastically deformed into a “barrel shape” so as to expand radially between the pair of metal plates. The side end portions of the barrel-shaped deforming portion are in contact with the pair of metal plates, respectively, the pair of metal plates are sandwiched between the flange portion and the flange of the fastener, and the fastener and the pair of metal plates are fixed.

  However, in the techniques shown in Patent Documents 1 to 3, although the reduction of the axial force at the time of fastening is improved and loosening of the fastener is suppressed, the fastener is tightened into the through hole formed in the composite panel. Since it is fastened to the composite panel, there is a problem that the axial force at the time of fastening cannot be sufficiently obtained and some loosening occurs. Moreover, since the fasteners conventionally used, such as Patent Documents 1 to 3, have a fastening structure with bolts and nuts, when the number of fastening points increases, it is necessary to set and tighten screws and bolts as many as the number of holes. There was a problem that increased.

  Accordingly, the problem to be solved by the present invention is a foamed resin laminated metal plate that is difficult to fasten, and a foamed resin laminate that can sufficiently fasten an axial force when the fastener is fastened and can be easily fastened.

And a fastener can be fastened in the position where the 1st member and 2nd member which were adhere | attached on a pair of metal plate contact | abut mutually, and overlap. That is, the fastener is not directly fastened to the foamed resin laminated metal plate, but the fastener is indirectly attached to the foamed resin laminated metal plate through the first member and the second member bonded to the pair of metal plates. Can be fastened.
Therefore, since the foamed resin layer is flexible, the axial force of the fastener cannot be sufficiently obtained, and the foamed resin laminated metal plate that is difficult to fasten is interposed between the first member and the second member that are bonded to the pair of metal plates. Thus, a high axial force can be obtained on the fastener by indirectly fastening the fastener. In addition, since the first member and the second member bonded to the pair of metal plates are in contact with each other and overlap each other, the fastener is fastened, so even if the pair of metal plates is thin An area for securing the axial force of the tool can be secured. And since it is the structure which fastens a fastener in the position where the 1st member and 2nd member which were adhere | attached on a pair of metal plate mutually contact and overlap, various fasteners from which a dimension differs can be applied. .
As described above, in the foamed resin laminated metal plate that is difficult to fasten, the axial force when the fastener is fastened can be sufficiently obtained, and the fastener can be easily fastened. As a result, the structure of the foamed resin laminated metal plate which reduced the weight while maintaining rigidity can be provided.

The overhanging portion 12 and the pair of metal plates 32 are bonded to each other at the contact surface 15 with an adhesive or an adhesive sheet. For the bonding, various materials can be used in addition to the adhesive and the adhesive sheet.

  The 2nd member 20 is formed in circular flat form, as shown in FIG.2 (b). The second member 20 is not limited to this, and can be formed in various shapes. The second member 20 has a circular through hole 24 formed substantially at the center. The through hole 24 is formed by penetrating in the plate thickness direction of the second member 20 with a through hole machining tool such as a drill. The through hole 24 is formed in substantially the same shape as the through hole 14 of the first member 10. Note that the through hole 24 may not be formed in the second member 20.

  As shown in FIG. 1, the second member 20 is disposed to face the opposite side (the lower side of the drawing in FIG. 1) of the pair of metal plates 32 facing the first member 10. The second member 20 is arranged so that the through hole 24 overlaps the through hole 14 of the first member 10.

  The second member 20 contacts the surface of the surrounding portion where the through-holes 33 of the pair of metal plates 32 are formed in the recessed portion provided on the opposite side to the first member 10 of the pair of metal plates 32. Touch. The second member 20 and the pair of metal plates 32 are bonded to each other at the contact surface 25 with an adhesive or an adhesive sheet. For the bonding, various materials can be used in addition to the adhesive and the adhesive sheet. Further, the second member 20 is disposed so as to overlap the bottom portion 13 of the first member 10.

  The first member 10 is formed such that the length of the cylindrical portion 11 is substantially the same as the thickness of the foamed resin laminated metal plate 30. More specifically, in the first member 10, the length of the cylinder portion 11 is such that one of the protruding portion 12 of the first member 10 and one of the pair of metal plates 32 abuts, and the second member and the pair of metal plates 32. When the other of the first and second members abuts, the bottom portion 13 of the first member 10 and the second member 20 are overlapped to form a length.

  At this time, the first member 10 and the second member 20 are pressed so as to sandwich the foamed resin laminated metal plate 30. Since the foamed resin laminated metal plate 30 is a soft material, when the first member 10 and the second member 20 are pressed so as to sandwich the foamed resin laminated metal plate 30 as shown in FIG. The pair of metal plates 32 bend and enter the foamed resin layer 31 side at the contact surfaces of the projecting portion 12 of the first member 10 and the pair of metal plates 32, which are the surfaces of the surrounding portions.

  The bottom portion 13 of the first member 10 and the second member 20 may be bonded to each other on the overlapping contact surface. For adhesion, an adhesive sheet or an adhesive can be applied. Thereby, the intensity | strength of a whole pair of patch plate improves. Therefore, a higher axial force can be obtained when the fastener is fastened to the pair of contact plates.

  As described above, according to the structure 101 of the foamed resin laminated metal plate according to the first embodiment, the cylindrical portion 11 and the bottom portion 13 are inserted into the through-hole 33 that penetrates the pair of metal plates 32 and the foamed resin layer 31. A pair of contact plates composed of the cup-shaped first member 10 and the flat plate-shaped second member 20 are arranged on both sides of the pair of metal plates 32. Here, the abutment surface 12 of the first member 10 and the contact surfaces of the pair of metal plates 32 and the contact surfaces 15 and 25 of the second member 20 and the pair of metal plates 32 are bonded. And a fastener can be fastened in the position where the bottom part 13 of the 1st member 10 and the 2nd member 20 contact | abut and mutually overlap. That is, the fastener is not directly fastened to the foamed resin laminated metal plate 30, and the first member 10 and the second member 20 bonded to the pair of metal plates 32 are used to the foamed resin laminated metal plate 30. The fastener can be indirectly tightened.

  Therefore, since the foamed resin layer 31 is flexible, the first member 10 and the first member 10 bonded to the pair of metal plates 32 and the foamed resin laminated metal plate 30 that are difficult to fasten due to insufficient axial force of the fasteners. A high axial force can be obtained on the fastener by indirectly fastening the fastener via the two members 20. In addition, since the first member 10 and the second member 20 bonded to the pair of metal plates 32 are in contact with each other and overlap each other, the fastener is fastened. Therefore, the pair of metal plates 32 is thin. However, it is possible to secure an area for securing the axial force of the fastener. Furthermore, since the first member 10 is formed in a cup shape, the contact area on the contact surface 15 with the pair of metal plates 32 of the overhanging portion 12 is increased, and the load applied to the pair of metal plates 32 is reduced. Can do. And since it is the structure which fastens a fastener in the position where the 1st member 10 and the 2nd member 20 which were adhere | attached on a pair of metal plate 32 mutually contact and overlap, various fasteners from which a dimension differs are applied. be able to.

  As described above, in the foamed resin laminated metal plate 30 that is difficult to fasten, the structure 101 of the foamed resin laminated metal plate can have a sufficient axial force when the fastener is fastened and can be fastened easily. . As a result, the structure 101 of the foamed resin laminated metal plate reduced in weight while maintaining rigidity can be provided.

For example, the overhang portion 22 may be formed so as not to be inclined with respect to the tube portion 21 and to extend in the vertical direction.

  The bottom portion 23 and the cylindrical portion 21 are inserted into the through holes 33 of the pair of metal plates 32 from the bottom portion 23 side until the protruding portion 22 contacts the pair of metal plates 32 and the bottom portion 23 overlaps the bottom portion 13 of the first member. Is done.

  The overhanging portion 22 is in contact with the surface of the peripheral portion where the through-holes 33 of the pair of metal plates 32 are formed in the recessed portion provided on one side of the pair of metal plates 32. The projecting portion 22 and the pair of metal plates 32 are bonded to each other at the contact surface 25 with an adhesive or an adhesive sheet. For the bonding, various materials can be used in addition to the adhesive and the adhesive sheet.

  The first member 10 and the second member 20 are formed such that the total length of the cylindrical portion 11 and the cylindrical portion 21 is substantially the same as the thickness of the foamed resin laminated metal plate 30. More specifically, the first member 10 and the second member 20 have a total length of the cylindrical portion 11 and the cylindrical portion 21 such that one of the protruding portion 12 of the first member 10 and the pair of metal plates 32 abuts. And when the overhang | projection part 22 of the 2nd member and the other of a pair of metal plate 32 contact | abut, it is long enough so that the bottom part 13 of the 1st member 10 and the bottom part 23 of the 2nd member 20 may overlap and contact. It is formed.

  At this time, the first member 10 and the second member 20 are pressed so as to sandwich the foamed resin laminated metal plate 30. Since the foamed resin laminated metal plate 30 is a soft material, when the first member 10 and the second member 20 are pressed so as to sandwich the foamed resin laminated metal plate 30 as shown in FIG. The pair of metal plates 32 bend and enter the foamed resin layer 31 side at the contact surfaces of the projecting portion 12 of the first member 10 and the pair of metal plates 32, which are the surfaces of the surrounding portions. In addition, the pair of metal plates 32 bend and enter the foamed resin layer 31 side at the contact surfaces of the overhanging portion 22 of the second member 20 and the pair of metal plates 32 that are the surface of the portion around the through hole 33. .

Therefore, a higher axial force can be obtained when the fastener is fastened to the pair of contact plates.

  Thus, according to the structure 102 of the foamed resin laminated metal plate according to the second embodiment, the cylindrical portions 11, 21 and the bottom portion 13 are formed in the through holes 33 that penetrate the pair of metal plates 32 and the foamed resin layer 31. , 23 are disposed on both sides of the pair of metal plates 32, each of which includes a cup-shaped first member 10 and a second member 20. Here, the projecting portions 12 and 22 of the first member 10 and the second member 20 are bonded to the contact surfaces 15 and 25 of the pair of metal plates 32. And a fastener can be fastened in the position where the bottom parts 13 and 14 of the 1st member 10 and the 2nd member 20 mutually contact | abut and overlap. That is, the fastener is not directly fastened to the foamed resin laminated metal plate 30, and the first member 10 and the second member 20 bonded to the pair of metal plates 31 are used for the foamed resin laminated metal plate 30. The fastener can be indirectly tightened.

A high axial force can be obtained on the fastener by indirectly fastening the fastener via the two members 20. In addition, since the first member 10 and the second member 20 bonded to the pair of metal plates 32 are in contact with each other and overlap each other, the fastener is fastened. Therefore, the pair of metal plates 32 is thin. However, it is possible to secure an area for securing the axial force of the fastener. Furthermore, since the first member 10 and the second member 20 are formed in a cup shape, the contact areas on the contact surfaces 15 and 25 of the projecting portions 12 and 22 with the pair of metal plates 32 increase, and a pair of metals The load applied to the plate 32 can be reduced. And since it is the structure which fastens a fastener in the position where the 1st member 10 and the 2nd member 20 which were adhere | attached on a pair of metal plate 32 mutually contact and overlap, various fasteners from which a dimension differs are applied. be able to.

  As described above, the foamed resin laminated metal plate structure 102 has a sufficient axial force when the fastener is fastened in the foamed resin laminated metal plate 30 that is difficult to fasten, and can easily fasten the fastener. . As a result, it is possible to provide a foamed resin laminated metal plate structure 102 that is light in weight while maintaining rigidity.

[Third embodiment]
Next, the structure which fastened the fastener with respect to the structure of the foaming resin laminated metal plate of this embodiment is demonstrated based on FIG.5 and FIG.6. FIG. 5 is a cross-sectional view showing the structure of the foamed resin laminated metal plate according to the third embodiment. FIG. 6: is sectional drawing which shows the state which fastened the to-be-fastened member to the structure of the foamed resin laminated metal plate which concerns on 3rd embodiment.

  First, the structure of the foamed resin laminated metal plate according to the third embodiment will be described with reference to FIG.

  As shown in FIG. 5, the structure 103 of the foamed resin laminated metal plate according to the third embodiment includes the structure 101 of the foamed resin laminated metal plate according to the first embodiment and a bolt that is a fastener. 41. The structure 101 of the foamed resin laminated metal plate according to the first embodiment described above is merely an example. In addition to the structure 102 of the foamed resin laminated metal plate according to the first embodiment described above, the structure 101 of the present invention is also included. Various embodiments of the structure of the foamed resin laminated metal plate can be used.

  The bolt 41 is inserted into the through hole 14 of the first member 10 and the through hole 24 of the second member 20 from the first member 10 side. Then, by using an adhesive or an adhesive sheet on the bonding surface between the bolt 41 and the bottom portion 13 of the first member 10, the bolt 41 is fixed to the first member 10, and the structure 103 of the foamed resin laminated metal plate is formed. Form.

  In the present embodiment, the bolt 41 is used as a fastener, but the present invention is not limited thereto. As the fastener, a caulking fastening bolt, a pierce nut, a nut, a stud bolt with a clip, a rivet, or the like can be used.

  Next, a state in which a member to be fastened is fastened to the structure 103 of the foamed resin laminated metal plate according to the third embodiment will be described with reference to FIG.

  As shown in FIG. 6, the fastener 40 includes a bolt 41 and a nut 42.

  The fastened member 50 is disposed on the second member 20 side of the structure 103 of the foamed resin laminated metal plate according to the third embodiment. Further, the fastened member 50 is made of, for example, a steel material, and includes through holes having substantially the same shape as the through hole 14 of the first member 10 and the through hole 24 of the second member 20.

  The fastened member 50 is fastened to the structure 103 of the foamed resin laminated metal plate by inserting the bolt 41 into the through hole and screwing the nut 42 from the front end side of the bolt 41. Thereby, the foamed resin laminated metal plate 30 and the fastened member 50 can be fastened via the fastener 40 regardless of the material of the foamed resin laminated metal plate 30.

  Thus, according to the structure 103 of the foamed resin laminated metal plate according to the third embodiment, since the foamed resin layer 31 is flexible, the axial force of the fastener cannot be sufficiently obtained and the fastening of the foamed resin laminated is difficult. The fastener 40 is indirectly fastened to the metal plate 30 via the first member 10 and the second member 20 bonded to the pair of metal plates 32. Therefore, a high axial force can be obtained at the fastener 40.

  In addition, the fastener 40 is fastened to a position where the first member 10 and the second member 20 bonded to the pair of metal plates 31 come into contact with each other and overlap each other. Therefore, even when the pair of metal plates 31 is thin, it is possible to secure an area for securing the axial force of the fastener 40.

  Further, the first member 10 and the second member 20 bonded to the pair of metal plates 31 are configured to fasten the fasteners 40 at positions where they abut and overlap each other, and the pair of metal plates is thin. In addition, since the area for securing the axial force of the fastener 40 can be secured, various types of fasteners can be easily fastened.

  As described above, the structure 103 of the foamed resin laminated metal plate is capable of sufficiently securing the axial force when the fastener 40 is fastened and easily fastened the fastener 40 in the foamed resin laminated metal plate 30 that is difficult to fasten. Can do. As a result, the structure 103 of the foamed resin laminated metal plate reduced in weight while maintaining rigidity can be provided.

[Structure of foamed resin laminated metal plate according to fourth embodiment]
Next, the structure of the foamed resin laminated metal plate according to the fourth embodiment will be described with reference to FIG. FIG. 7 is a cross-sectional view showing a structure of a foamed resin laminated metal plate according to the fourth embodiment.

  As shown in FIG. 7, the foamed resin laminated metal plate structure 104 includes a foamed resin laminated metal plate 30 in which a foamed resin is disposed between a pair of metal plates 32 and a foamed resin layer 31 is formed. A through-hole 33 that penetrates the pair of metal plates 32 and the foamed resin layer 31 of the laminated metal plate 30, and is disposed on one side of the pair of metal plates 32 so as to face the through-holes 33, so A first member 10 in contact therewith.

  The pair of metal plates 32 is formed of, for example, a steel plate, an aluminum alloy plate, industrial plastic, or a laminated plate thereof. Further, the pair of metal plates 32 and the foamed resin layer 31 may be bonded by an adhesive, or may be heat-sealed by heating and pressing. The foamed resin laminated metal plate 30 is formed by foaming the foamed resin layer 31 at a predetermined foaming temperature. The foamed resin laminated metal plate 30 includes, for example, a pair of metal plates 32 which are aluminum alloy plates having a thickness of 0.3 mm, and a foamed resin layer 31 having a thickness of 3.3 to 4.2 mm obtained by laminating and foaming the foamed resin. Formed with.

  The through-hole 33 is formed in, for example, a circular shape so as to penetrate the pair of metal plates 32 and the foamed resin layer 31 by machining using a through-hole machining tool such as a drill. In the present embodiment, the through-hole 33 is formed in a circular shape and has a diameter that is substantially the same as the diameter of the cylindrical tube portion 11 of the first member 10 described later. The through-hole 33 does not need to be formed in a circular shape, and may be formed in substantially the same shape as a cylindrical portion 11 of the first member 10 described later.

  The pair of metal plates 32 may be formed such that the surface of the peripheral portion where the through-hole 33 is formed is recessed from the surface of the other portion, with one side metal plate into which the first member 10 described later is inserted. preferable. The peripheral portion where the through-hole 33 is formed corresponds to a portion where a first member 10 described later comes into contact. Further, the other portion is in the vicinity of the peripheral portion where the through hole 33 is formed, and corresponds to a portion other than the peripheral portion where the through hole 33 is formed.

  Here, the peripheral portion where the through hole 33 is formed is such that when the first member 10 described later is bonded to one side of the pair of metal plates 32, the first member 10 is paired with the pair of metal plates 32. It is preferable to be formed so as to be recessed so as to be disposed inside the surface of the other part. That is, it is preferable that a recess having substantially the same thickness as the thickness of an overhanging portion 12 of the first member 10 described later is formed in the peripheral portion where the through hole 33 is formed.

  Indentations formed in the pair of metal plates 32 in the peripheral portion where the through hole 33 is formed are formed by heating and pressurizing before inserting the first member 10 described later into the through hole 33. .

  Since the first member 10 does not protrude from the surface of the pair of metal plates 32 due to the dents, the thickness direction of the structure 104 of the foamed resin laminated metal plate depends on the installation location of the structure 104 of the foamed resin laminated metal plate. It can also be applied when there is a limit to the thickness of the film.

  Moreover, when inserting the 1st member 10 in the through-hole 33 of a pair of metal plate 32, the dent formed in the surface of the surrounding part in which the through-hole 33 is formed plays the role of a guide, and a pair of metal plate The first member 10 can easily be accommodated in the 32 through holes 33.

  The first member 10 is preferably formed of, for example, a steel plate, an aluminum alloy plate, an industrial plastic, or a laminated plate thereof, and a member having higher rigidity than the pair of metal plates 32. Further, the first member 10 may be formed thicker than the pair of metal plates 32.

  The first member 10 extends outwardly from the cylindrical portion 11 and the outer peripheral edge of one end of the cylindrical portion 11 in the same manner as FIG. 2A showing the first member 10 of the first embodiment. The projecting portion 12 formed in this manner and the bottom portion 13 formed in communication with the other end of the cylindrical portion 11 are formed into a cup shape. In the first member 10, a circular through hole 14 is formed substantially at the center of the bottom portion 13. The through hole 14 is formed by penetrating in the plate thickness direction of the bottom portion 13 of the first member 10 with a through hole machining tool such as a drill. In addition, the through hole 14 does not need to be formed in the first member 10.

  As shown in FIG. 7, the first member 10 is disposed to face one side of the pair of metal plates 32 (upper side in the drawing in FIG. 7).

  The cylinder part 11 is formed in a cylindrical shape, for example. The overhanging portion 12 has a certain degree of inclination with respect to the cylindrical portion 11 and is formed in an annular shape, for example. Moreover, the bottom part 13 is formed in circular shape, for example. The cylinder part 11, the overhang | projection part 12, and the bottom part 13 which comprise the 1st member 10 are not restricted to the shape shown to Fig.2 (a), It is possible to form in various shapes. For example, the overhanging portion 12 may be formed so as not to be inclined with respect to the cylindrical portion 11 and to extend in the vertical direction.

  The bottom portion 13 and the cylindrical portion 11 are inserted from the bottom portion 13 side with respect to one side of the pair of metal plates 32, the overhanging portion 12 abuts against the pair of metal plates 32, and the bottom portion 13 of the pair of metal plates 32. Inserted into the through holes 33 of the pair of metal plates 32 until reaching the other side.

  The overhanging portion 12 is in contact with the surface of the peripheral portion where the through-holes 33 of the pair of metal plates 32 are formed in the recessed portion provided on one side of the pair of metal plates 32. The overhanging portion 12 and the pair of metal plates 32 are bonded to each other at the contact surface 15 with an adhesive or an adhesive sheet. For the bonding, various materials can be used in addition to the adhesive and the adhesive sheet.

  The first member 10 is formed such that the length of the cylindrical portion 11 is substantially the same as the thickness of the foamed resin laminated metal plate 30. More specifically, the first member 10 has a length of the cylindrical portion 11 such that when the protruding portion 12 of the first member 10 and one of the pair of metal plates 32 abut, the bottom portion 13 of the first member 10 It is formed with a length arranged at the same position as the surface of the other side of the pair of metal plates 32.

  At this time, the first member 10 is pressed against the foamed resin laminated metal plate 30. Since the foamed resin laminated metal plate 30 is a soft material, as shown in FIG. 7, when the first member 10 is pressed against the foamed resin laminated metal plate 30, it is the surface of the portion around the through-hole 33. The pair of metal plates 32 bend and enter the foamed resin layer 31 side at the contact surface between the protruding portion 12 of the first member 10 and the pair of metal plates 32.

  Thus, according to the structure 104 of the foamed resin laminated metal plate according to the fourth embodiment, the cup-shaped first member 10 is inserted into the through-hole 33 that penetrates the pair of metal plates 32 and the foamed resin layer 31. The cylindrical portion 11 and the bottom portion 13 are inserted from one side of the pair of metal plates 32 to the other side. Here, the projecting portion 12 of the first member 10 and the contact surface 15 of the pair of metal plates 32 are bonded. Then, a fastener can be fastened to the bottom 13 of the first member 10. That is, the fastener is not directly fastened to the foamed resin laminated metal plate 30, but the fastener is indirectly attached to the foamed resin laminated metal plate 30 via the first member 10 bonded to the pair of metal plates 32. Can be fastened.

  Therefore, since the foamed resin layer 31 is flexible, the axial force of the fastener is not sufficient, and the foamed resin laminated metal plate 30 that is difficult to fasten is interposed through the first member 10 bonded to the pair of metal plates 32. Thus, a high axial force can be obtained on the fastener by indirectly fastening the fastener. Moreover, since it is a structure which fastens a fastener to the 1st member 10 adhere | attached on a pair of metal plate 32, even if a pair of metal plate 32 is thin, it is for securing the axial force of a fastener. The area can be secured. Furthermore, since the first member 10 is formed in a cup shape, the contact area between the protruding portion 12 and the pair of metal plates 32 is increased, and the load applied to the pair of metal plates 32 can be reduced. And since it is the structure which fastens a fastener to the 1st member 10 adhere | attached on a pair of metal plate 32, various fasteners from which a dimension differs can be applied.

  As described above, in the foamed resin laminated metal plate 30 that is difficult to fasten, the axial force when the fastener is fastened can be sufficiently obtained, and the fastener can be easily fastened. As a result, it is possible to provide a foamed resin laminated metal plate structure 104 that is lightweight while maintaining rigidity.

It is preferable to be formed so as to be recessed so as to be disposed inside the surface of the other part. That is, it is preferable that a recess having substantially the same thickness as the thickness of the second member 70 is formed in a portion where the second member 70 on the other side of the pair of metal plates 32 contacts.

  The recess formed on the other side of the pair of metal plates 32 at the portion where the second member 70 abuts is heated and pressurized before the second member 70 abuts on the other side of the pair of metal plates 32. Is formed.

  Since the second member 70 does not protrude from the surface of the pair of metal plates 32 due to this recess, the thickness direction of the structure 106 of the foamed resin laminated metal plate is related to the installation location of the structure 106 of the foamed resin laminated metal plate. It can also be applied when there is a limit to the thickness of the film.

  In addition, when the second member 70 is brought into contact with the other side of the pair of metal plates 32, a recess formed on the other surface of the pair of metal plates 32 serves as a guide, and the pair of metal plates 32 The second member 70 is easily accommodated on the other side.

Thereby, the whole intensity | strength of the structure 106 of a foamed resin laminated metal plate improves. Therefore, when a fastener is fastened to the first member 60 and the second member 70, a higher axial force can be obtained.

  FIG. 12 shows an example of the overall configuration of the foamed resin laminated metal plate structure 105 (including the foamed resin laminated metal plate structure 106 which is a modification of the fifth embodiment) according to the fifth embodiment described above. Based on Here, FIG. 12 is a top view showing an example of the entire structure of the foamed resin laminated metal plate according to the fifth embodiment.

  As shown in FIG. 12, the foamed resin laminated metal plate structure 105 according to the fifth embodiment is installed in the substantially rectangular foamed resin laminated metal plate 30 and the peripheral portions of the four sides of the foamed resin laminated metal plate 30. A plurality of through-holes 33, a first member 60 that faces the plurality of through-holes 33 and is disposed in the periphery of one of the four sides of the pair of metal plates 32 and contacts one of the pair of metal plates 32; It has. The structure 106 of the foamed resin laminated metal plate according to the modification of the fifth embodiment is further disposed in the peripheral part of the other four sides of the pair of metal plates 32 so as to face the plurality of through holes 33.

The cup-shaped recess 61 is inserted from one side of the pair of metal plates 32 to the other side. Here, the plate-like member 65 of the first member 60 and the contact surfaces 66 of the pair of metal plates 32 are bonded. A fastener can be fastened to the plurality of recesses 61 of the first member 60. That is, the fastener is not directly fastened to the foamed resin laminated metal plate 30, and the foamed resin laminated metal plate 30 is interposed via the plurality of recesses 61 of the first member 60 bonded to the pair of metal plates 32. A plurality of fasteners can be indirectly fastened.

  Therefore, since the foamed resin layer 31 is flexible, the axial force of the fastener cannot be sufficiently obtained, and the foamed resin laminated metal plate 30 that is difficult to fasten is interposed through the first member 60 bonded to the pair of metal plates 32. Thus, a high axial force can be obtained on the fastener by indirectly fastening the fastener. Moreover, since it is a structure which fastens a fastener to the 1st member 60 adhere | attached on a pair of metal plate 32, even if a pair of metal plate 32 is thin, it is for securing the axial force of a fastener. The area can be secured. Further, since the first member 60 is formed by the plurality of concave portions 61 and the plate-like member 65, the contact area between the first member 60 and the pair of metal plates 32 becomes the same as the area of the plate-like member 65. Since the contact area is large, the load applied to the pair of metal plates 32 can be greatly reduced, and the strength of the foamed resin laminated metal plate 30 can be greatly improved. And since it is the structure which fastens a fastener to the recessed part 61 of the 1st member 60 adhere | attached on a pair of metal plate 32, various fasteners from which a dimension differs can be applied. Moreover, since the 1st member 60 is formed with the some recessed part 61 and the plate-shaped member 65, a several fastener can be fastened at once with respect to the 1st member 60, and working efficiency is improved. be able to.

By fastening the fastener indirectly through the two members 70, a high axial force can be obtained at the fastener. In addition, since the first member 60 and the second member 70 bonded to the pair of metal plates 32 are configured to fasten the fasteners at positions where they abut against each other, the pair of metal plates 32 is thin. However, it is possible to secure an area for securing the axial force of the fastener. Further, since the first member 60 is formed by the plurality of concave portions 61 and the plate-like member 65, the contact area between the first member 60 and the pair of metal plates 32 becomes the same as the area of the plate-like member 65. Since the contact area is large, the load applied to the pair of metal plates 32 can be greatly reduced, and the strength of the foamed resin laminated metal plate 30 can be greatly improved. And since it is the structure which fastens a fastener in the position where the 1st member 60 and the 2nd member 70 which were adhere | attached on a pair of metal plate 32 mutually contact and overlap, various fasteners from which a dimension differs are applied. be able to. Moreover, since the 1st member 60 is formed with the some recessed part 61 and the plate-shaped member 65, a several fastener can be fastened at once with respect to the 1st member 60, and working efficiency is improved. be able to. Furthermore, since the first member 60 includes a bent portion 67 that bends along the end surface 34 of the foamed resin laminated metal plate 30, the end surface of the foamed resin laminated metal plate 30 is guarded by the bent portion 67 of the first member 60. The strength of the structure of the foamed resin laminated metal plate 30 can be improved. Further, the bending portion 67 serves as a guide, and the work of assembling the first member 60 to the foamed resin metal plate 30 is facilitated.
