Description
本発明は、セル構造を有する多孔質金属材の設置構造に関し、特に高い気孔率を有するセル構造多孔質金属材を被固定部材の表面に沿って設置、固定するための設置構造に関する。 The present invention relates to an installation structure for a porous metal material having a cell structure, and particularly to an installation structure for installing and fixing a cell structure porous metal material having a high porosity along the surface of a member to be fixed.
ハニカム構造に組み立てられた金属ハニカム材や、発泡チタン及び発泡アルミニウムに代表される発泡バルク金属材など、多くの種類のセル構造を有する多孔質金属材が知られている。また、近年、メッキ法などを利用してスポンジなどの多孔質形状を転写したセル構造を有する多孔質金属材なども開発されている（例えば、特許文献１参照）。 There are known porous metal materials having many types of cell structures, such as metal honeycomb materials assembled in a honeycomb structure, and foamed bulk metal materials typified by foamed titanium and foamed aluminum. In recent years, a porous metal material having a cell structure in which a porous shape such as a sponge is transferred using a plating method or the like has been developed (for example, see Patent Document 1).
このようなセル構造を有する多孔質金属材は、金属部分の性質の利用を目的とする場合と、セル（気孔）部分の性質の利用を目的とする場合がある。前者には、金属部分の強度や靭性などの機械的性質、伝熱性などの熱的性質、電気伝導度や誘電特性などの電気的・磁気的性質などを利用する場合がある。また、後者には、衝撃吸収、断熱、比重、物質透過などの気孔部分自体の性質の利用、また機能性微粒子の担持など他の機能性物質との組み合わせにおける基材としての利用の場合がある。このようなセル構造を有する多孔質金属材は、その材料としての特徴を活かすように被固定部材上に取り付けられて複合材料として使用されることが多い。 The porous metal material having such a cell structure may be used for the purpose of utilizing the properties of the metal portion or the properties of the cell (pore) portion. The former may utilize mechanical properties such as strength and toughness of the metal part, thermal properties such as heat transfer, and electrical and magnetic properties such as electrical conductivity and dielectric properties. In the latter case, there are cases where the properties of the pore portion itself such as shock absorption, heat insulation, specific gravity, substance permeation, etc. are used, or as a base material in combination with other functional substances such as loading of functional fine particles. . A porous metal material having such a cell structure is often used as a composite material by being mounted on a member to be fixed so as to make use of the characteristics of the material.
ここで被固定部材上に沿ってセル構造を有する多孔質金属材を配置、固定して、複合材料を形成する場合がある。 Here, a composite material may be formed by arranging and fixing a porous metal material having a cell structure along the member to be fixed.
例えば、特許文献２では拡散接合によりセル構造を有する多孔質金属材を被固定部材上に沿って配置、固定する複合材料の形成方法が開示されている。多孔質金属材を被固定部材である金属板上に配置して、金属粉を含む接着剤でこれらを接着させる。これを加熱すると、金属粉が多孔質金属材及び金属板の相互に拡散してこれらを拡散接合するのである。かかる接合では、接合界面が金属組織的に連続になるために強固な接合を得ることができる。
近年、９０％以上の高い気孔率を有するセル構造多孔質金属材が開発され、その材料としての特徴を活かすように被固定部材の表面に沿って設置、固定する必要が生じている。 In recent years, a cellular porous metal material having a high porosity of 90% or more has been developed, and it is necessary to install and fix it along the surface of the member to be fixed so as to make use of the characteristics of the material.
ここで、特許文献２に開示の拡散接合を用いた方法では、拡散接合される部分が被固定部材と多孔質金属材との接触部分だけである。故に、高い気孔率を有するセル構造多孔質金属材の如きでは、多孔質金属材の接着表面に露出する多くの気孔のため、前記した接触面積が非常に小さいのである。故に、拡散接合によって得られる接合強度は低い。また、被固定部材が金属を拡散しない、熱に弱いＦＲＰやプラスチックである場合にはかかる方法を用いることはできない。 Here, in the method using diffusion bonding disclosed in Patent Document 2, the portion to be diffusion-bonded is only the contact portion between the fixed member and the porous metal material. Therefore, in the case of a cell structure porous metal material having a high porosity, the contact area described above is very small because of many pores exposed on the bonding surface of the porous metal material. Therefore, the bonding strength obtained by diffusion bonding is low. Further, such a method cannot be used when the member to be fixed is FRP or plastic which does not diffuse metal and is weak against heat.
また、高い気孔率を有するセル構造多孔質金属材を被固定部材上にねじやボルトで押圧、固定しようとしても、圧縮に弱い高気孔率多孔質金属材は座屈してしまって固定することは困難である。 Also, even when trying to press and fix a porous metal material having a high porosity on a fixed member with a screw or bolt, the high porosity porous metal material that is weak against compression is buckled and fixed. Have difficulty.
本発明は上記したような状況に鑑みてなされたものであって、ＦＲＰやプラスチックなどの熱に弱い素材からなる被固定部材の表面に沿ってもセル構造多孔質金属材を設置、固定が可能であって、しかも互いを強固に固定することが可能なセル構造多孔質金属材の設置構造を提供する。 The present invention has been made in view of the above situation, and it is possible to install and fix a cellular structure porous metal material along the surface of a fixed member made of a heat-sensitive material such as FRP or plastic. And the installation structure of the cellular structure porous metal material which can fix each other firmly is provided.
本発明は、セル構造を有する多孔質金属材を被固定部材の第１面上に配置してこれを固定するための設置構造である。前記多孔質金属材は前記被固定部材側へ向けて圧縮形成された圧縮凹部を有し、前記被固定部材の前記第１面上に固定された軸体は前記圧縮凹部において前記多孔質金属材を貫通する取付穴を貫通し、前記軸体の突出端部は前記圧縮凹部内にて前記多孔質金属材を前記被固定部材に向けて押圧するフランジ部を有することを特徴とする。 The present invention is an installation structure for arranging and fixing a porous metal material having a cell structure on the first surface of a member to be fixed. The porous metal material has a compression recess formed by compression toward the member to be fixed, and the shaft fixed on the first surface of the member to be fixed is the porous metal material in the compression recess. The projecting end portion of the shaft body has a flange portion that presses the porous metal material toward the fixed member in the compression recess.
かかる設置構造によれば、セル構造多孔質金属材を被固定部材に向けて押圧する圧縮凹部の圧縮強度が高いため、セル構造多孔質金属材と被固定部材とを互いに強固に固定することが可能である。しかも、拡散接合法などのように熱を加える必要がないので、被固定部材が金属や無機系材質の場合だけでなく、ＦＲＰやプラスチックなどであってもセル構造多孔質金属材の固定が可能である。 According to such an installation structure, since the compressive concave portion that presses the cellular structure porous metal material toward the member to be fixed has high compressive strength, the cell structure porous metal material and the member to be fixed can be firmly fixed to each other. Is possible. Moreover, since it is not necessary to apply heat as in the diffusion bonding method, it is possible to fix the cellular structure porous metal material not only when the member to be fixed is a metal or inorganic material, but also with FRP or plastic. It is.
本発明の１つの実施例は、セル構造を有する多孔質金属材を被固定部材の第１面上に配置してこれを固定する方法であって、多孔質金属材を被固定部材上に向けて押圧して固定する設置構造である。すなわち、多孔質金属材は被固定部材側へ向けて圧縮形成された圧縮凹部を有し、圧縮凹部には多孔質金属材を貫通する取付穴が形成されている。一方、被固定部材の第１面上には軸体が固定されており、該軸体は取付穴を貫通して多孔質金属材の圧縮凹部内に突出している。軸体の突出端部は圧縮凹部内にて多孔質金属材を被固定部材に向けて押圧するフランジ部を有する。 One embodiment of the present invention is a method of disposing a porous metal material having a cell structure on a first surface of a member to be fixed and fixing the same, with the porous metal material facing the member to be fixed. It is an installation structure that is pressed and fixed. That is, the porous metal material has a compression recess that is compressed toward the fixed member side, and an attachment hole that penetrates the porous metal material is formed in the compression recess. On the other hand, a shaft body is fixed on the first surface of the fixed member, and the shaft body passes through the attachment hole and protrudes into the compression recess of the porous metal material. The protruding end portion of the shaft body has a flange portion that presses the porous metal material toward the fixed member in the compression recess.
かかる構造において、圧縮凹部の底部近傍は高い密度を有するため、さらなる圧縮に対して圧縮抵抗が高められている。故に、多孔質金属材を被固定部材に向けてさらに強固に押圧できるので、セル構造多孔質金属材と被固定部材とを互いに強固に固定することが可能である。 In such a structure, since the vicinity of the bottom of the compression recess has a high density, the compression resistance is increased against further compression. Therefore, since the porous metal material can be pressed more firmly toward the member to be fixed, the cell structure porous metal material and the member to be fixed can be firmly fixed to each other.
また、環状板体の中心孔には軸体が貫挿されている。環状板体は、フランジ部と多孔質金属材との間に配置され、フランジ部が多孔質金属材を被固定部材に向けて押圧するとともに、環状板体も多孔質金属材によって押圧されている。環状板体は、その周縁部に沿って突部を有しており、環状板体が多孔質金属材に押圧されるとともに、突部が多孔質金属材のセル内に侵入する。 A shaft body is inserted through the center hole of the annular plate. The annular plate body is disposed between the flange portion and the porous metal material. The flange portion presses the porous metal material toward the fixed member, and the annular plate body is also pressed by the porous metal material. . The annular plate has a protrusion along its peripheral edge, and the annular plate is pressed against the porous metal material, and the protrusion enters the cell of the porous metal material.
かかる構造において、多孔質金属材と軸体とが強固に締結される。軸体は被固定部材に固定されているため、多孔質金属材が被固定部材に強固に固定されるのである。ここで、環状板体とフランジ部とが一体をなしていると、より強固に多孔質金属材と軸体を締結できる。これにより、更に多孔質金属材が被固定部材に強固に固定できるので好ましい。また、金属や無機系材質の場合だけでなく、ＦＲＰやプラスチックなどの熱に弱い素材からなる被固定部材の表面に沿ってもセル構造多孔質金属材を設置、固定が可能である。 In such a structure, the porous metal material and the shaft body are firmly fastened. Since the shaft body is fixed to the fixed member, the porous metal material is firmly fixed to the fixed member. Here, when the annular plate body and the flange portion are integrated, the porous metal material and the shaft body can be fastened more firmly. This is preferable because the porous metal material can be firmly fixed to the fixed member. In addition to the case of a metal or an inorganic material, the cell structure porous metal material can be installed and fixed along the surface of a fixed member made of a heat-sensitive material such as FRP or plastic.
ところで、被固定部材にはこれを貫通する固定穴が設けられており、軸体が被固定部材の第１面と対をなす第２面から突出するように固定穴を貫通している。軸体の突出端部は被固定部材の第２面上に固定されている。この第２面に固定された軸体の突出端部は、該第２面に沿って拡がる第２のフランジ部を有する。第２のフランジ部が被固定部材の第２面を第１面側へ向けて押圧することで軸体が被固定部材に固定されている。 By the way, the fixing member is provided with a fixing hole penetrating the fixing member, and the shaft body passes through the fixing hole so as to protrude from the second surface paired with the first surface of the fixing member. The protruding end portion of the shaft body is fixed on the second surface of the fixed member. The protruding end portion of the shaft body fixed to the second surface has a second flange portion that extends along the second surface. The shaft body is fixed to the fixed member by the second flange portion pressing the second surface of the fixed member toward the first surface.
なお、第２のフランジ部は被固定部材の第２面上に与えられた肉盛硬化部に埋入されて被固定部材に固定されている。ここで、肉盛硬化部は、樹脂からなることが好ましい。多孔質金属材がオープンセル構造であると、例えば、多孔質金属材を透過して被固定部材の第１面に達した水分が被固定部材の固定穴を通って、本体内部に浸透してしまうのである。これを肉盛硬化部が防止するのである。 In addition, the 2nd flange part is embed | buried in the build-up hardening part given on the 2nd surface of the to-be-fixed member, and is being fixed to the to-be-fixed member. Here, it is preferable that the build-up hardening part consists of resin. When the porous metal material has an open cell structure, for example, moisture that has permeated through the porous metal material and reached the first surface of the fixed member permeates the inside of the main body through the fixing hole of the fixed member. It ends up. This is prevented by the build-up hardening part.
また、被固定部材の第２面において、固定穴の周囲を切削した凹部を設けて、第２のフランジ部を凹部内に収容してもよい。かかる構造によれば、被固定部材の第２面に凸部がなく、表面の平面性を保てるのである。故に、被固定部材はさらに本体部の面上に沿って配置して、ボルトや接着剤で固定できるのである。 Moreover, the 2nd surface of a to-be-fixed member may provide the recessed part which cut the circumference | surroundings of the fixing hole, and may accommodate a 2nd flange part in a recessed part. According to such a structure, the second surface of the member to be fixed has no convex portion, and the surface flatness can be maintained. Therefore, the member to be fixed can be further arranged along the surface of the main body and fixed with a bolt or an adhesive.
ここで、被固定部材の第1面には熱硬化性樹脂やエポキシなどからなる接着層を与えて多孔質金属材を付加的に固定しても良い。特に、接着層に多孔質金属材が埋入しているとより強固にこれを固定できて好ましいのである。 Here, the porous metal material may be additionally fixed by providing an adhesive layer made of a thermosetting resin or epoxy on the first surface of the fixed member. In particular, it is preferable that a porous metal material is embedded in the adhesive layer because it can be more firmly fixed.
本発明の１つの実施例であるセル構造を有する多孔質金属材を被固定部材の上に配置して固定するための設置構造について、図１乃至図６を用いて詳細に説明する。 An installation structure for arranging and fixing a porous metal material having a cell structure, which is one embodiment of the present invention, on a fixed member will be described in detail with reference to FIGS.
多孔質金属材１０は、図１に示すような、ハニカム構造に組み立てられた金属ハニカム材や、図２に示すような、発泡チタンなどの発泡バルク金属材などである。また、オープンセル構造の多孔質体に限らず、クローズドセル構造の多孔質体であってもよい。すなわち、多孔質金属材１０は、バルク金属内に多くのセル（気孔）１０ａを含むような金属材である。 The porous metal material 10 is a metal honeycomb material assembled in a honeycomb structure as shown in FIG. 1 or a foamed bulk metal material such as foamed titanium as shown in FIG. Moreover, the porous body is not limited to the open cell structure, and may be a closed cell structure. That is, the porous metal material 10 is a metal material including many cells (pores) 10a in the bulk metal.
図３に示すように、多孔質金属材１０は、ＦＲＰや樹脂、金属などからなる被固定部材１１の第１面１１ａ上に沿って配置されている。多孔質金属材１０の第１面１０ａには、被固定部材１１側に向けて圧縮形成された圧縮凹部１２が形成されている。すなわち、圧縮凹部１２の底部１２ａ近傍は高い密度を有し、さらなる圧縮に対して圧縮抵抗が高められている。圧縮凹部１２の底部１２ａには、多孔質金属材１０を貫通する貫通穴１３ａが形成されている。なお、被固定部材１１には、これを貫通し貫通穴１３ａと連通する貫通穴１３ｂが形成されている。 As shown in FIG. 3, the porous metal material 10 is disposed along the first surface 11a of the fixed member 11 made of FRP, resin, metal, or the like. A compression recess 12 is formed on the first surface 10a of the porous metal material 10 so as to be compressed toward the fixed member 11 side. That is, the vicinity of the bottom 12a of the compression recess 12 has a high density, and the compression resistance is increased against further compression. A through hole 13 a that penetrates the porous metal material 10 is formed in the bottom 12 a of the compression recess 12. The fixed member 11 is formed with a through hole 13b that passes through the fixed member 11 and communicates with the through hole 13a.
図４を併せて参照すると、リベット体１６は、円柱状の軸体１６ａと軸体の一端部に形成された円盤上のフランジ部１６ｂとからなる。リベット体１６の軸体１６ａは、多孔質金属材１０の第１面１０ａから貫通穴１３ａ及び１３ｂを貫通している。被固定部材１１の第２面１１ｂへ突出した軸体１６ａの突出端部は、被固定部材１１の第２面１１ｂに沿って押しつぶされて拡がった変形部１７となっている。かかる構造により、変形部１７とフランジ部１６ｂとの間に位置する多孔質金属１０及び被固定部材１１を軸体１６ａが互いに密着固定せしめるのである。ここで、フランジ部１６ｂは、多孔質金属材１０を被固定部材１１に向けて押圧しているが、圧縮凹部１２の底部１２ａはこれに対する大なる圧縮抵抗を有しているため、多孔質金属１０及び被固定部材１１を互いに強固に密着固定せしめることができるのである。換言すれば、被固定部材１１に植設されて固定された軸体１６ａに多孔質金属材１０が固定されているのである。なお、リベット体１６のフランジ部１６ｂは多孔質金属材１０の圧縮凹部１２内に収容されていると、多孔質金属材１０の第１面１０ａの平面性を保てるため好ましい。 Referring to FIG. 4 together, the rivet body 16 includes a cylindrical shaft body 16a and a flange portion 16b on a disk formed at one end of the shaft body. The shaft body 16 a of the rivet body 16 passes through the through holes 13 a and 13 b from the first surface 10 a of the porous metal material 10. The protruding end portion of the shaft body 16 a that protrudes to the second surface 11 b of the fixed member 11 is a deformed portion 17 that is crushed and expanded along the second surface 11 b of the fixed member 11. With this structure, the shaft body 16a tightly fixes the porous metal 10 and the fixed member 11 positioned between the deformable portion 17 and the flange portion 16b. Here, the flange portion 16b presses the porous metal material 10 toward the member 11 to be fixed, but the bottom portion 12a of the compression recess 12 has a large compression resistance against this, so the porous metal material 10 10 and the fixed member 11 can be firmly fixed to each other. In other words, the porous metal material 10 is fixed to the shaft body 16a that is implanted and fixed to the fixed member 11. Note that it is preferable that the flange portion 16b of the rivet body 16 is accommodated in the compression recess 12 of the porous metal material 10 because the flatness of the first surface 10a of the porous metal material 10 can be maintained.
ここで図３及び図５に示すように、歯付きワッシャー１９をリベット体１６のフランジ部１６ｂと多孔質金属材１０との間に挿入しても良い。歯付きワッシャー１９は環状板体であって、その周縁部に沿って板体から略垂直に立ち上がる突部１９ａを有する。リベット体１６のフランジ部１６ｂが多孔質金属材１０を被固定部材１１に向けて押圧すると、歯付きワッシャー１９の突部１９ａが多孔質金属材１０のセル１０ａ（図１及び２を参照）内に侵入するのである。かかる構造により、リベット体１６の軸ぶれが減じられて、多孔質金属１０及び被固定部材１１を互いに強固に密着固定せしめることができるのである。 Here, as shown in FIGS. 3 and 5, a toothed washer 19 may be inserted between the flange portion 16 b of the rivet body 16 and the porous metal material 10. The toothed washer 19 is an annular plate, and has a protrusion 19a that rises substantially vertically from the plate along its peripheral edge. When the flange portion 16b of the rivet body 16 presses the porous metal material 10 toward the fixed member 11, the protrusion 19a of the toothed washer 19 is in the cell 10a of the porous metal material 10 (see FIGS. 1 and 2). Intrusions. With such a structure, the shaft runout of the rivet body 16 is reduced, and the porous metal 10 and the fixed member 11 can be firmly and firmly fixed to each other.
また、図６に示すように、歯付きワッシャー１９はリベット体１６のフランジ部１６ｂと一体に形成されていても良い。すなわち、フランジ部１６ｂの周縁部に沿って略垂直に突部１６ｃが形成されているのである。リベット体１６のフランジ部１６ｂが多孔質金属材１０を被固定部材１１に向けて押圧すると、フランジ部１６ｂの突部１６ｃが多孔質金属材１０のセル１０ａ内に侵入するのである。かかる構造により、同様に、リベット体１６の軸ぶれが減じられて、多孔質金属１０及び被固定部材１１を互いに強固に密着固定せしめることができるのである。 Further, as shown in FIG. 6, the toothed washer 19 may be formed integrally with the flange portion 16 b of the rivet body 16. That is, the protrusion 16c is formed substantially perpendicularly along the peripheral edge of the flange portion 16b. When the flange portion 16 b of the rivet body 16 presses the porous metal material 10 toward the fixed member 11, the protrusion 16 c of the flange portion 16 b enters the cell 10 a of the porous metal material 10. With this structure, similarly, the shaft runout of the rivet body 16 is reduced, and the porous metal 10 and the fixed member 11 can be firmly and firmly fixed to each other.
ところで、図３に示すように、リベット体１６の変形部１７は、被固定部材１１の第２面１１ｂ上に与えられた肉盛り硬化部２０に埋め込まれて固定されていてもよい。肉盛り硬化部２０はシリコンやエポキシなどの樹脂であることが好ましい。特に、多孔質金属材１０がオープンセル構造からなる多孔質材である場合、水がこれを透過するため（図３の矢印Ａを参照）、貫通穴１３ｂに沿って被固定部材１１の内側に進入することを防止できるのである。 By the way, as shown in FIG. 3, the deformed portion 17 of the rivet body 16 may be embedded and fixed in the build-up curing portion 20 provided on the second surface 11 b of the fixed member 11. The build-up hardening part 20 is preferably a resin such as silicon or epoxy. In particular, when the porous metal material 10 is a porous material having an open cell structure, water passes through the porous metal material 10 (see the arrow A in FIG. 3), so that the inner side of the fixed member 11 along the through hole 13b. It is possible to prevent entry.
多孔質金属材１０は、円柱状に取り除いた除去部２１を有する。除去部２１からは、被固定部材１１の第１面１１ａが露出している。かかる露出部において被固定部材１１を貫通する貫通穴２２を削孔する。貫通穴２２の直径は、除去部２１の直径よりも小である。リベット体１６によって一体となった多孔質金属材１０及び被固定部材１１は、本体ステイ２３の貫通穴２５と貫通穴２２とを連通させるように本体ステイ２３の上に配置される。固定ボルト２４ａは貫通穴２２を介して本体ステイ２３の貫通穴２５を貫通し、反対側でナット２４ｂによって固定される。 The porous metal material 10 has a removal portion 21 removed in a columnar shape. From the removal portion 21, the first surface 11a of the fixed member 11 is exposed. The through hole 22 that penetrates the fixed member 11 is drilled in the exposed portion. The diameter of the through hole 22 is smaller than the diameter of the removal portion 21. The porous metal material 10 and the fixed member 11 integrated by the rivet body 16 are disposed on the main body stay 23 so that the through hole 25 and the through hole 22 of the main body stay 23 communicate with each other. The fixing bolt 24a passes through the through hole 25 of the main body stay 23 through the through hole 22, and is fixed by the nut 24b on the opposite side.
なお、被固定部材１１の第1面１１ａに熱硬化性樹脂やエポキシなどからなる接着層を与えてもよい。この接着層に多孔質金属材１０が埋入しているとより強固に多孔質金属材１０と被固定部材１１とを密着固定できて好ましい。 Note that an adhesive layer made of a thermosetting resin or epoxy may be provided on the first surface 11a of the member 11 to be fixed. It is preferable that the porous metal material 10 is embedded in the adhesive layer because the porous metal material 10 and the member 11 to be fixed can be firmly fixed.
上記した実施例によれば、金属や無機系材質の場合だけでなく、ＦＲＰやプラスチックなどの熱に弱い素材からなる被固定部材１１の表面に沿っても、セル構造を有する多孔質金属材１０を設置し、固定することが可能であって、しかも互いを強固に固定することが可能なのである。 According to the above-described embodiment, the porous metal material 10 having a cell structure is formed not only in the case of a metal or an inorganic material but also along the surface of the fixed member 11 made of a heat-sensitive material such as FRP or plastic. Can be installed and fixed, and can be firmly fixed to each other.
本発明のさらなる１つの実施例であるセル構造を有する多孔質金属材を被固定部材の上に配置して固定するための設置構造について、図７を用いて詳細に説明する。 An installation structure for disposing and fixing a porous metal material having a cell structure on a member to be fixed, which is another embodiment of the present invention, will be described in detail with reference to FIG.
図７に示すように、実施例１と同様に、多孔質金属材１０及び被固定部材１１は、多孔質金属材１０の圧縮凹部１２からこれらを貫通して設けられた貫通穴１３ａ及び１３ｂに貫挿されたリベット体１６によって互いに密着固定されている。なお詳細については実施例１において述べたので、詳述しない。ここで、リベット体１６の変形部１７は、被固定部材１１の第２面１１ｂの表面を切削したざぐり部１８内にある。故に、変形部１７をその中に埋入する肉盛り硬化部２０もざぐり部１８内に与えられるのである。かかる構成により、被固定部材１１の第２面１１ｂは平面を維持できるのである。 As shown in FIG. 7, as in the first embodiment, the porous metal material 10 and the fixed member 11 are inserted into the through holes 13 a and 13 b provided through the compression recess 12 of the porous metal material 10. The rivet bodies 16 are inserted and fixed to each other. Since details are described in the first embodiment, they will not be described in detail. Here, the deformed portion 17 of the rivet body 16 is in a counterbore portion 18 obtained by cutting the surface of the second surface 11 b of the fixed member 11. Therefore, the build-up hardening part 20 which embeds the deformation | transformation part 17 in it is also given in the counterbore part 18. FIG. With this configuration, the second surface 11b of the fixed member 11 can maintain a flat surface.
以上の如く、リベット体１６によって一体となった多孔質金属材１０及び被固定部材１１は、例えば、アルミニウムの板材からなる取付板２７の第１面２７ａ上に接着材によって固定される。若しくは、多孔質金属材１０の一部に貫通穴である切削穴３１を設けて、露出した被固定部材１１の第１面１１ａから被固定部材１１を貫通する貫通穴３２を設ける。ここで切削穴３１の直径は、貫通穴３２の直径よりも大である。取付板２７には、貫通穴３２とほぼ同じ直径の貫通穴３３が設けられており、貫通穴３２及び３３が一直線で並んで連通するように多孔質金属材１０及び被固定部材１１と取付板２７とが配置される。 As described above, the porous metal material 10 and the fixed member 11 integrated by the rivet body 16 are fixed to the first surface 27a of the mounting plate 27 made of, for example, an aluminum plate by an adhesive. Or the cutting hole 31 which is a through hole is provided in a part of the porous metal material 10, and the through hole 32 which penetrates the to-be-fixed member 11 from the exposed 1st surface 11a of the to-be-fixed member 11 is provided. Here, the diameter of the cutting hole 31 is larger than the diameter of the through hole 32. The mounting plate 27 is provided with a through hole 33 having substantially the same diameter as the through hole 32, and the porous metal material 10 and the fixed member 11 and the mounting plate so that the through holes 32 and 33 communicate with each other in a straight line. 27 are arranged.
固定用ボルト３４ａは貫通穴３２及び３３に貫挿されるとともに、固定用ボルト３４ａの頭部は切削穴３１内にある。固定用ボルト３４ａは取付板２７の第２面２７ｂ側からナット３４ｂと螺合される。ここで、リベット体１６の変形部１７及び肉盛り硬化部２０はざぐり部１８内にあるから、被固定部材１１と取付板２７とを密着固定できるのである。また、固定用ボルト３４ａとナット３４ｂとは間に圧縮座屈されやすい多孔質金属材を介在させていないから、互いに強固に固定できるのである。 The fixing bolt 34 a is inserted into the through holes 32 and 33, and the head of the fixing bolt 34 a is in the cutting hole 31. The fixing bolt 34a is screwed to the nut 34b from the second surface 27b side of the mounting plate 27. Here, since the deformed portion 17 and the build-up hardening portion 20 of the rivet body 16 are in the counterbore portion 18, the fixed member 11 and the mounting plate 27 can be tightly fixed. In addition, since the fixing bolt 34a and the nut 34b do not interpose a porous metal material that is easily compressed and buckled, they can be firmly fixed to each other.
なお、本体ステイ２３上には、取付板２７及び被固定部材１１が固定ボルト４４ａ及びナット４４ｂによって固定される。この場合においても固定ボルト４４ａの頭部は、多孔質金属材１０に形成された切削穴３５内にあるが、上記した構造と同一であるので詳述しない。 On the main body stay 23, the mounting plate 27 and the fixed member 11 are fixed by fixing bolts 44a and nuts 44b. Also in this case, the head of the fixing bolt 44a is in the cutting hole 35 formed in the porous metal material 10, but it will not be described in detail because it is the same as the structure described above.
上記した取付構造によれば、リベット体１６によって一体となった多孔質金属材１０及び被固定部材１１を剛性の高い取付板２７上に沿って設置、固定することができる。故に、ＦＲＰなどの被固定部材１１の剛性を取付板２７で補強することが可能である。これとともに、多孔質金属材１０を被固定部材１１とともに、取付板２７から着脱することが容易にできるのである。故に、多孔質金属材１０の経年劣化などにより交換することが簡単にできるのである。 According to the mounting structure described above, the porous metal material 10 and the fixed member 11 integrated by the rivet body 16 can be installed and fixed along the highly rigid mounting plate 27. Therefore, the rigidity of the fixed member 11 such as FRP can be reinforced by the mounting plate 27. At the same time, the porous metal material 10 can be easily detached from the mounting plate 27 together with the fixed member 11. Therefore, it is possible to easily replace the porous metal material 10 due to deterioration over time.
