Description

本発明は、反り、ねじれ、たわみ及び衝撃に対する高い耐久性を備えた高強度パネルの連結構造、及び複数の高強度パネルを連結したパネル連結体に関する。 The present invention relates to a connection structure for a high-strength panel having high durability against warping, twisting, bending, and impact, and a panel connecting body that connects a plurality of high-strength panels.

従来から、中芯材として金属製のハニカム構造体を用意し、その表裏面に金属製薄板を接着させて成るパネルが知られている。このハニカム構造体として、例えば、アルミニウム箔を六角形の蜂の巣状に連続成形して積層したものが知られている。このパネルは、強度が高く且つ軽量であるという特長を有し、住宅やビルのドア、庇、壁材、床材、間仕切りなどの建築用資材として、幅広く用いられている。 2. Description of the Related Art Conventionally, there has been known a panel in which a metal honeycomb structure is prepared as a core material, and a metal thin plate is adhered to the front and back surfaces thereof. As this honeycomb structure, for example, a structure in which aluminum foil is continuously formed in a hexagonal honeycomb shape and laminated is known. This panel has features of high strength and light weight, and is widely used as a building material such as a door of a house or a building, an eave, a wall material, a floor material, a partition, and the like.

しかし、ハニカム構造体の表裏面に、単層の金属製薄板を接着させただけでは、用途によっては十分な強度が得られない場合がある。特に、反り、ねじれ、たわみ、衝撃に対する十分な耐久性が得られない場合がある。 However, simply attaching a single-layer metal thin plate to the front and back surfaces of the honeycomb structure may not provide sufficient strength depending on the application. In particular, sufficient durability against warping, twisting, bending, and impact may not be obtained.

本発明は、上記した課題に基づき成されたものであり、その目的は、反り、ねじれ、たわみ、衝撃に対する高い耐久性を備えた高強度パネルの連結構造、及びパネル連結体を提供することである。 The present invention has been made based on the above-described problems, and an object of the present invention is to provide a connection structure of a high-strength panel having high durability against warpage, twisting, bending, and impact, and a panel connection body. is there.

上記目的を達成するために、本発明の第１の態様は、ハニカム構造を有する板状の中芯材と、中芯材の表裏面に接着されたアラミド積層体とを有する高強度パネルであって、アラミド積層体は、アラミド繊維を含むアラミド層と、アラミド層の表裏面に接着された第１金属層及び第２金属層とを備える。 In order to achieve the above object, a first aspect of the present invention is a high-strength panel having a plate-shaped core material having a honeycomb structure, and an aramid laminate bonded to the front and back surfaces of the core material. The aramid laminate includes an aramid layer containing aramid fibers, and a first metal layer and a second metal layer adhered to the front and back surfaces of the aramid layer.

アラミド繊維は、伸び・縮みが少なく、引っ張り強度が高いという特長を有している。このアラミド繊維を含むアラミド層に金属層を接着したアラミド積層体を、ハニカム構造を有する板状の中芯材の表裏面に接着することにより、単層の金属製薄板を接着させた従来のパネルに比べて、反り、ねじれ、たわみ、衝撃に対する耐久性を高めることができる。 Aramid fibers have the characteristics of low elongation / shrinkage and high tensile strength. A conventional panel in which a single-layer thin metal plate is bonded by bonding an aramid laminate in which a metal layer is bonded to an aramid layer containing the aramid fiber to front and back surfaces of a plate-shaped core material having a honeycomb structure. As compared with the above, durability against warpage, twisting, bending, and impact can be increased.

本発明の第２の態様は、第１の態様に係わる高強度パネルの連結構造であって、連結部材と、第１固着具と、第２固着具とを備える。連結部材は、高強度パネルの側面から突出する第１突出部及び第２突出部を有する。第１固着具は、連結する一方の高強度パネルの第１突出部と他方の高強度パネルの第２突出部とが高強度パネルの表裏面の法線方向に重なった状態で、高強度パネルの表面側から第１突出部及び第２突出部を貫通して、第１突出部と第２突出部と表面側の金属層とを固着する。第２固着具は、連結する一方の高強度パネルの第２突出部と他方の高強度パネルの第１突出部が高強度パネルの表裏面の法線方向に重なった状態で、高強度パネルの裏面側から第１突出部及び第２突出部を貫通して、第１突出部と第２突出部と裏面側の金属層とを固着する。 A second aspect of the present invention is a connection structure for a high-strength panel according to the first aspect, and includes a connection member, a first fastener, and a second fastener. The connection member has a first protrusion and a second protrusion protruding from the side surface of the high-strength panel. The first fastener is a high-strength panel in a state in which the first protruding portion of one high-strength panel and the second protruding portion of the other high-strength panel overlap in the normal direction of the front and back surfaces of the high-strength panel. The first and second protrusions are fixed to the metal layer on the front side by penetrating the first and second protrusions from the surface side of the first protrusion. The second fixing tool is provided in a state where the second protruding portion of one of the high-strength panels and the first protruding portion of the other high-strength panel overlap with each other in the normal direction of the front and back surfaces of the high-strength panel. The first protrusion, the second protrusion, and the metal layer on the back side are fixedly penetrating through the first protrusion and the second protrusion from the back side.

第１固着具及び第２固着具の各々が、表面側及び裏面側から第１突出部及び第２突出部及び金属層をそれぞれ固着するため、アラミド積層体の反り、ねじれ、たわみ、衝撃に対する高い耐久性を維持したまま、複数の高強度パネルを連結することができる。 Since each of the first fixing tool and the second fixing tool fixes the first protruding portion, the second protruding portion, and the metal layer from the front surface side and the back surface side, respectively, the aramid laminate has high resistance to warping, twisting, bending, and impact. A plurality of high-strength panels can be connected while maintaining durability.

本発明の第３の態様は、第２の態様に係わる高強度パネルの連結構造を備えるパネル連結体であって、第１固着具及び第２固着具は、パネル連結体の長手方向に平行に配列されている。 A third aspect of the present invention is a panel connector including the high-strength panel connection structure according to the second aspect, wherein the first fastener and the second fastener are parallel to the longitudinal direction of the panel connector. Are arranged.

高強度パネル同士の連結部がパネル連結体の長手方向に平行に配列されていることにより、パネル連結体の長手方向に加わる反り、ねじれ、たわみ、衝撃に対する耐久性を高めることができる。また、高強度パネルの連結構造を備えることにより、パネル連結体の短手方向に加わる反り、ねじれ、たわみ、衝撃に対する耐久性を高めることができる。 Since the connecting portions of the high-strength panels are arranged in parallel to the longitudinal direction of the panel connector, durability against warping, twisting, bending, and impact applied in the longitudinal direction of the panel connector can be increased. In addition, by providing the connection structure of the high-strength panel, it is possible to enhance the durability of the panel connection body against warping, twisting, bending, and impact applied in the short direction.

以上説明したように、本発明によれば、第１固着具及び第２固着具の各々が、表面側及び裏面側から第１突出部及び第２突出部及び金属層をそれぞれ固着するため、アラミド積層体の反り、ねじれ、たわみ、衝撃に対する高い耐久性を維持したまま、複数の高強度パネルを連結することができる。 As described above, according to the present invention, each of the first fastener and the second fastener fixes the first protrusion, the second protrusion, and the metal layer from the front side and the back side, respectively. A plurality of high-strength panels can be connected while maintaining high durability of the laminate against warping, twisting, bending, and impact.

以下図面を参照して、本発明の実施の形態を説明する。図面の記載において同一部分には同一符号を付している。 Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same parts are denoted by the same reference numerals.

（第１実施形態）
図１を参照して、第１実施形態に係わる高強度パネル１の構造を説明する。高強度パネル１は、互いに平行な表面及び裏面を有する平板状のパネルであり、図１は、高強度パネル１の表裏面に垂直な切断面に沿った断面図である。 (1st Embodiment)
The structure of the high-strength panel 1 according to the first embodiment will be described with reference to FIG. The high-strength panel 1 is a flat panel having a front surface and a back surface parallel to each other, and FIG. 1 is a cross-sectional view taken along a cut surface perpendicular to the front and back surfaces of the high-strength panel 1.

高強度パネル１は、ハニカム構造を有する板状の中芯材１０と、中芯材１０の表裏面に接着されたアラミド積層体（１１、１２）とを有する。中芯材１０は、例えば、アルミ箔を六角形の蜂の巣状に連結成型して、複数積層させたハニカム構造体である。ハニカム構造体は、軽量、高強度、高剛性、表面積が広い、衝撃吸収性が高い、整流作用や断熱性能に優れている。 The high-strength panel 1 includes a plate-shaped core material 10 having a honeycomb structure, and aramid laminates (11, 12) bonded to the front and back surfaces of the core material 10. The core material 10 is, for example, a honeycomb structure in which a plurality of aluminum foils are connected and formed into a hexagonal honeycomb shape and stacked. The honeycomb structure has light weight, high strength, high rigidity, a large surface area, high shock absorption, excellent rectification and heat insulation performance.

アラミド積層体（１１、１２）は、中芯材１０の表面及び裏面にそれぞれ接着されている。各アラミド積層体（１１、１２）は、アラミド繊維を含むアラミド層（１３、１６）と、アラミド層（１３、１６）の表裏面に接着された第１金属層（１４、１７）及び第２金属層（１５、１８）と、を備える。第１実施形態において、中芯材１０の表面に第２金属層１５が接着され、中芯材１０の裏面に第２金属層１８が接着されている。 The aramid laminates (11, 12) are bonded to the front and back surfaces of the core material 10, respectively. Each of the aramid laminates (11, 12) includes an aramid layer (13, 16) containing aramid fiber, a first metal layer (14, 17) bonded to the front and back surfaces of the aramid layer (13, 16), and a second aramid layer (13, 16). Metal layers (15, 18). In the first embodiment, the second metal layer 15 is adhered to the surface of the core 10, and the second metal layer 18 is adhered to the back of the core 10.

アラミド層（１３、１６）に含まれるアラミド繊維とは、全芳香族ポリアミドからなる合成繊維であり、骨格となるベンゼン核が直線的に並んだパラ系と、ジグザグ状に並んだメタ系の２種類に大別される。高強度パネル１において、高強度で高弾性、低伸縮などの優れた特性を示すパラ系を用いることが望ましいが、耐熱性や難燃性に優れるメタ系を用いても構わない。 The aramid fibers contained in the aramid layers (13, 16) are synthetic fibers made of wholly aromatic polyamide, and include two types, a para-series in which benzene nuclei serving as a skeleton are linearly arranged, and a meta-series in which zigzag-like benzene nuclei are arranged. Broadly classified into types. In the high-strength panel 1, it is desirable to use a para-system exhibiting excellent properties such as high strength, high elasticity and low expansion and contraction, but a meta-system excellent in heat resistance and flame retardancy may be used.

第１金属層（１４、１７）は、例えば、厚さ１．０ｍｍのステンレス膜（ＳＵＳ３０４）からなる。第２金属層（１５、１８）は、例えば、厚さ１．０ｍｍのアルミニウム膜からなる。アラミド層（１３、１６）の厚さは１ｍｍ弱であるため、アラミド積層体（１１、１２）の厚さは、３ｍｍ弱となる。中芯材１０の厚さは約７６ｍｍであり、高強度パネル１の全体厚さは、約８２ｍｍとなる。ただし、各部材の厚さは用途に応じて変更可能である。 The first metal layers (14, 17) are made of, for example, a stainless steel film (SUS304) having a thickness of 1.0 mm. The second metal layer (15, 18) is made of, for example, an aluminum film having a thickness of 1.0 mm. Since the thickness of the aramid layers (13, 16) is less than 1 mm, the thickness of the aramid laminates (11, 12) is less than 3 mm. The thickness of the core material 10 is about 76 mm, and the overall thickness of the high-strength panel 1 is about 82 mm. However, the thickness of each member can be changed according to the application.

なお、上記した積層構造に他の層が介在しても構わない。つまり、中芯材１０とアラミド積層体（１１、１２）との間、アラミド層（１３、１６）と第１金属層（１４、１７）との間、アラミド層（１３、１６）と第２金属層（１５、１８）との間に、他の部材が介在していても構わない。例えば、後述するように、複数の高強度パネル１を連結するために用いる連結部材（２０、２０’、図３参照）は、高強度パネル１の側面（連結箇所）において、その一部分が中芯材１０とアラミド積層体（１１、１２）との間に介在している。 Note that another layer may be interposed in the above-described laminated structure. That is, between the core 10 and the aramid laminates (11, 12), between the aramid layers (13, 16) and the first metal layers (14, 17), and between the aramid layers (13, 16) and the second Other members may be interposed between the metal layers (15, 18). For example, as described later, a connecting member (20, 20 ′, see FIG. 3) used to connect a plurality of high-strength panels 1 has a part of the center on a side surface (connecting portion) of the high-strength panel 1. It is interposed between the material 10 and the aramid laminates (11, 12).

図２を参照して、図１の高強度パネル１の製造方法を説明する。先ず、アラミド積層体１１を作成する。具体的には、アラミド層１３、第１金属層１４及び第２金属層１５を、２液型のウレタン樹脂系接着剤で接着する。このとき、接着剤を金属層（１４、１５）の接着面に塗布する方法（第１の方法）と、接着剤をアラミド層１３の接着面に塗布する方法（第２の方法）とがあるが、どちらの方法であっても構わない。また、アラミド層１３に対して、第１金属層１４と第２金属層１５を個々に接着してもよいし、第１金属層１４と第２金属層１５を同時に接着しても構わない。アラミド積層体１２もアラミド積層体１１と同様にして作成することができる。 With reference to FIG. 2, a method of manufacturing the high-strength panel 1 of FIG. 1 will be described. First, the aramid laminate 11 is prepared. Specifically, the aramid layer 13, the first metal layer 14, and the second metal layer 15 are bonded with a two-component urethane resin-based adhesive. At this time, there are a method (first method) of applying the adhesive to the bonding surface of the metal layers (14, 15), and a method (second method) of applying the adhesive to the bonding surface of the aramid layer 13. However, either method may be used. Further, the first metal layer 14 and the second metal layer 15 may be individually bonded to the aramid layer 13 or the first metal layer 14 and the second metal layer 15 may be bonded simultaneously. The aramid laminate 12 can be prepared in the same manner as the aramid laminate 11.

次に、中芯材１０の表面及び裏面にアラミド積層体（１１、１２）を接着する。具体的には、中芯材１０及びアラミド積層体（１１、１２）を、２液型のウレタン樹脂系接着剤で接着する。これにより、図１に示す高強度パネル１が完成する。２液型のウレタン樹脂系接着剤の代わりに、２液型のエポキシ樹脂系接着剤を用いても構わない。 Next, the aramid laminates (11, 12) are bonded to the front and back surfaces of the core material 10. Specifically, the core 10 and the aramid laminates (11, 12) are bonded with a two-component urethane resin-based adhesive. Thus, the high-strength panel 1 shown in FIG. 1 is completed. Instead of the two-part urethane resin-based adhesive, a two-part epoxy resin-based adhesive may be used.

製造方法は、図２に示した例に限定されない。例えば、後述する実験例で作成した高強度パネルは、次の手順により作成した。中芯材１０の表面及び裏面に第２金属層（１５、１８）をそれぞれ接着する。その後、第２金属層（１５、１８）上に、アラミド層（１３、１６）を配置し、アラミド層（１３、１６）の接着面に接着剤をそれぞれ塗布する。最後に、アラミド層１３に、第１金属層（１４、１７）をそれぞれ接着する。 The manufacturing method is not limited to the example shown in FIG. For example, a high-strength panel created in an experimental example described later was created by the following procedure. The second metal layers (15, 18) are bonded to the front and back surfaces of the core material 10, respectively. Thereafter, the aramid layers (13, 16) are arranged on the second metal layers (15, 18), and an adhesive is applied to the bonding surfaces of the aramid layers (13, 16), respectively. Finally, the first metal layers (14, 17) are bonded to the aramid layer 13, respectively.

以上説明したように、アラミド繊維は、伸び・縮みが少なく、引っ張り強度が高いという特長を有している。第１の実施形態によれば、このアラミド繊維を含むアラミド層（１３、１６）に金属層（１４、１５、１７、１８）を接着したアラミド積層体（１１、１２）を、ハニカム構造を有する板状の中芯材１０の表裏面に接着している。これにより、引っ張り応力及び圧縮応力が最大となる高強度パネル１の表裏面に、伸び・縮みが少なく、引っ張り強度が高いアラミド層（１３、１６）を配置することができる。よって、単層の金属製薄板を接着させた従来のパネルに比べて、反り、ねじれ、たわみ、衝撃に対する耐久性が高い高強度パネル１を提供することができる。 As described above, the aramid fiber has the characteristics that it has little elongation / shrinkage and high tensile strength. According to the first embodiment, the aramid laminates (11, 12) in which the metal layers (14, 15, 17, 18) are bonded to the aramid layers (13, 16) containing the aramid fibers have a honeycomb structure. It is adhered to the front and back surfaces of the plate-shaped core material 10. Thereby, the aramid layers (13, 16) with little elongation / shrinkage and high tensile strength can be arranged on the front and back surfaces of the high-strength panel 1 where the tensile stress and the compressive stress are maximized. Therefore, it is possible to provide the high-strength panel 1 having higher durability against warping, twisting, bending, and impact than a conventional panel to which a single-layer metal thin plate is adhered.

（実験例）
次に、上記した高強度パネル１の反り、ねじれ、たわみ、衝撃に対する耐久性の高さを確かめるために、発明者が行った実験例を説明する。 (Experimental example)
Next, an example of an experiment performed by the inventor to check the durability of the high-strength panel 1 against warping, twisting, bending, and impact will be described.

実施形態に係わる高強度パネル１と、比較例に係わる従来パネルとをそれぞれ作成し、高強度パネル１及び従来パネルについて三点曲げ試験を行って、一次降伏強さ、弾性率、最大強さをそれぞれ求めた。 The high-strength panel 1 according to the embodiment and the conventional panel according to the comparative example are respectively prepared, and a three-point bending test is performed on the high-strength panel 1 and the conventional panel to determine a primary yield strength, an elastic modulus, and a maximum strength. I asked for each.

高強度パネル１は、第１金属層（ステンレス板）と第２金属層（アルミニウム板）の間にアラミド層を挿入したパネルであり、従来パネルは、第１金属層（ステンレス板）と第２金属層（アルミニウム板）をアラミド層を介さずに直接、接着したパネルである。ハニカム構造を有する板状の中芯材は、両者ともに同じものを使用している。また、高強度パネル１及び従来パネルのそれぞれについて、異なる接着剤を用いて２種類の試験片を作成した。具体的には、株式会社オーシカ製２液ウレタン樹脂系オーシカダインＴＵ−４０９（以後、「ＴＵ−４０９」と略する。）と、株式会社オーシカ製２液エポキシ樹脂系オーシカダインＴＥ−２１６（以後、「ＴＥ−２１６」と略する。）と、を用いた。 The high-strength panel 1 is a panel in which an aramid layer is inserted between a first metal layer (stainless steel plate) and a second metal layer (aluminum plate). This is a panel in which a metal layer (aluminum plate) is directly bonded without using an aramid layer. The same plate-shaped core material having a honeycomb structure is used for both. In addition, two types of test pieces were prepared for each of the high-strength panel 1 and the conventional panel using different adhesives. Specifically, a two-liquid urethane resin-based oshicadyne TU-409 (hereinafter abbreviated as "TU-409") manufactured by Osika Co., Ltd. TE-216 ").

実験結果を表１、図７、図８に示す。一次降伏強さ、弾性率、及び最大強さは、何れも、従来パネルに比べて高強度パネル１の方が高い値となった。この結果は、使用する接着剤（ＴＵ−４０９、ＴＥ−２１６）の種類によらず、得られた。接着剤別では、一次降伏強さ、弾性率はＴＥ−２１６の方が高い値となり、最大強さはＴＵ−４０９の方が高い値となった。 The experimental results are shown in Table 1, FIG. 7, and FIG. The primary yield strength, the elastic modulus, and the maximum strength were all higher in the high-strength panel 1 than in the conventional panel. This result was obtained irrespective of the type of adhesive (TU-409, TE-216) used. By adhesive, the primary yield strength and elastic modulus were higher for TE-216, and the maximum strength was higher for TU-409.

全てのパネルで、一次降伏強さに達した際に圧子周辺のアルミハニカムが座屈した。その後、座屈が治まってからパネル全体のたわみが始まり２次ピークが見られ、曲げ強さの最大値（最大強さ）を示し、支持台方のアルミニウムやアルミ接着面の破断となった。アラミド繊維を使った高強度パネル１は、アラミド繊維を入れなかった従来パネルでは見られなかった、３次ピークが確認された。 In all panels, when the primary yield strength was reached, the aluminum honeycomb around the indenter buckled. Thereafter, after the buckling had subsided, the entire panel began to bend, a secondary peak was observed, the maximum value of the bending strength (maximum strength) was exhibited, and the aluminum or aluminum bonding surface of the support was broken. In the high-strength panel 1 using the aramid fiber, a tertiary peak was observed, which was not observed in the conventional panel without the aramid fiber.

（第２実施形態）

図３は、第２実施形態に係わる高強度パネルの連結構造を示す断面図である。連結する２枚の高強度パネル（１、１’）の端部（連結箇所）には、連結部材（２０、２０’）がそれぞれ設けられている。連結部材（２０、２０’）は互いに同じ構造を有しているが、高強度パネル（１、１’）に対して表裏面が逆向きに取り付けられている。以後、連結部材２０を例に取って説明を続け、連結部材２０’の説明は省略する。 FIG. 3 is a cross-sectional view illustrating a connection structure of a high-strength panel according to the second embodiment. Connection members (20, 20 ') are provided at the ends (connection portions) of the two high strength panels (1, 1') to be connected. The connecting members (20, 20 ') have the same structure as each other, but are attached to the high-strength panel (1, 1') in opposite directions. Hereinafter, the description will be continued by taking the connecting member 20 as an example, and the description of the connecting member 20 'will be omitted.

連結部材２０（ジョイント用アルミ型材）は、高強度パネル１の側面（連結箇所）から突出する第１突出部２０ａ及び第２突出部２０ｂを有する。第１突出部２０ａは高強度パネル１の裏面へ向かって細くなるように傾斜した凸部を有する。高強度パネル（１、１’）の裏面側の第１金属層（１７、１７’）は、高強度パネル（１、１’）の端部から凸部の側面まで、連結部材２０に沿って延出している。第２突出部２０ｂは、ナット２２を内包している。第１突出部２０ａ及び第２突出部２０ｂの各々には、高強度パネル１の表裏面の法線方向（つまり、積層方向）に貫通する穴が形成されている。 The connecting member 20 (aluminum-shaped member for joint) has a first protruding portion 20a and a second protruding portion 20b protruding from the side surface (the connecting portion) of the high-strength panel 1. The first protruding portion 20 a has a protruding portion that is inclined so as to become thinner toward the back surface of the high-strength panel 1. The first metal layer (17, 17 ') on the back surface side of the high-strength panel (1, 1') extends along the connecting member 20 from the end of the high-strength panel (1, 1 ') to the side surface of the projection.
