Due to the warping phenomenon of the rectangular metal plate of the shearing force, it is difficult to ensure that the shear strength of the shearing force is generally determined by the reinforcing material (reinforcing strip) being latticed with f' to ensure the strength of the f force. . Even if the shear-reducing endurance is ensured, it is difficult to maintain a stable load characteristic (recovery force characteristic) for the (4) progressing overshoot after the (4) progress and the alternating load of the positive and negative. Therefore, it is necessary to reduce the aspect ratio. It is necessary to configure the majority of the reinforcing strips to be the weight of the shearing load of the 2 sheets relative to the shearing shear load relative to the shear strength of the borrowed ribs.

The present invention has been made in view of the above problems, and its object is to improve the shear strength of an anisotropic reinforcing metal plate. Means for Solving the Problem In order to solve the above problems, the anisotropic reinforcing metal sheet of the present invention has a high shear strength in a specific direction, and has a rectangular metal plate; the first frame member is along the aforementioned The first direction and the second direction of the outer edge of the metal plate are arranged in 201043757, and are fixed to the metal plate so as to face the metal plate in a direction along the width direction; and the reinforcing member is along the first direction or the aforementioned Configuration in the 2nd direction. In the anisotropic reinforcing metal plate, the reinforcing member may be fixed to the metal plate so as to face the metal plate in a wide direction. The anisotropic reinforcing metal plate may have a gap between the first frame member and the reinforcing member. In the anisotropic reinforcing metal plate, the dimension of the first direction of the metal plate may be larger than the dimension of the second direction, and further may be disposed at a central portion of the first direction of the metal plate along the second direction. The second frame member may be disposed between the first frame member and the second frame member disposed along the second direction.

[Embodiment] Embodiments for carrying out the invention Hereinafter, a third embodiment of the present invention will be described with reference to Figs. 1 to 3 . The anisotropic reinforcing metal sheet of the present embodiment has a high shear strength in a specific direction and stably maintains the shearing shear strength until reaching a large deformation region. That is, the anisotropic reinforcing metal plate of the present embodiment has a reinforcing structure in which the shear warp load of the rectangular metal plate which is mainly subjected to the shearing force can be extracted, and the shearing load required for the blade is secured. Fig. 1 is a view showing an anisotropic reinforcing metal plate according to the first embodiment, (a) is a front view, (b) is a cross-sectional view, and (C) is a longitudinal sectional view. As shown in Fig. 1, the anisotropic reinforcing metal plate 100 is mainly composed of a rectangular metal plate 1, a frame-like frame portion (peripheral frame material) 2, and a plate-shaped reinforcing member 3. The metal plate 1 is formed of a metal such as steel or a light metal, and has a square metal plate having a width of about 〇〇mm, a south degree hi of about 900 mm, and a thickness t of about 3.2 mm. In the present embodiment, 'as a material of the metal plate 1, The use of the soft point sS4 frame portion 2 of the stress point ay=30kN/cm2, Young's coefficient E=20, 500kN/cm2 is arranged along the first direction along the outer edge of the metal plate 1 The first frame member 2a and one of the first frame members 2b are arranged in a frame shape along one of the second direction along the outer edge of the metal plate 1. The frame portion 2 is used to improve the bending rigidity of the metal plate [201043757 plane]. In order to resist the shear stress and then act on the oblique principal stress of the metal plate, and the 'frame 2 is designed to have a cross-sectional area amount which shows elasticity when the metal plate 1 is sheared and lowered, the shear of the metal plate 1 can be prevented. The first frame members 2a and 2b are, for example, strip-shaped plates having a width b2 of about 65 mm. The first frame members 2a and 2b have a rectangular cross-sectional shape having a width b2 larger than the thickness t2. The first frame members 2a, 2b are arranged along the outer edge of the metal plate 1, and are wide in the direction of the face (wide) The web is disposed opposite to the metal plate 1. Generally, in the cross-sectional shape having a long cross direction and a short cross direction, such as a rectangular cross section, the long direction is wide and the short direction is thickness. Therefore, in the present embodiment, the width direction is In the case of having a short-and a long-direction cross-sectional shape, it means a surface along the longitudinal direction of the cross-section. The first frame members 2a, 2b are fixed to the metal plate 1, for example, in a dot shape, a line shape or a planar shape. The first frame members 2a and 2b and the metal plate 1 are joined by, for example, welding or an adhesive. The i-frame members 2a and 2b are disposed on both sides of the metal plate, and the outer edge portion of the metal plate 1 is The reinforcing member 3 is sandwiched between the second frame member 2a and the pair of second frame member holes. The reinforcing member 3 is, for example, an f-shaped plate having a width b3 of about 50 mm and a thickness t3 of about 丨2 mm. The reinforcing members 3 are arranged perpendicular to each other. One of the first frame members 2a and 2b in the direction of the ground is disposed. In the present embodiment, the reinforcing member 3 is disposed substantially parallel to the m-th member 2b along the first frame member 2b. It is arranged along the second direction along the outer edge of the metal plate i. Furthermore, the metal plate 1 is positive (four), supplementing The strong member 3 may also be disposed in the first direction of the outer edge of the plate 1. 'The reinforcing member 3 has a shape in which the width b3 is larger than the thickness of the rectangular carrier surface, and 7 201043757 is disposed opposite to the metal plate 1 in the width b3 direction. The reinforcing member 3 is connected to the pair of reinforcing members 3 by a connecting member 9 such as a bolt or a nut, for example, by joining the reinforcing members 3 to the metal plate 1 and fixing the metal to the metal plate 1 . The reinforcing member 3 is fixed to the metal plate 1 by a plurality of connecting members 9 disposed at substantially equal intervals in the width bl direction of the metal plate 1. The both end portions of the reinforcing member 3 and the frame portion 2 are separated from each other. There is a gap formed between them. Further, the both end portions of the reinforcing member 3 and the frame portion 2 do not necessarily have to be separated from each other, and may be in contact with each other. At this time, the reinforcing member 3 and the frame portion 2 are not joined to each other. The reinforcing member 3 is attached to the inner region of the frame portion 2 of the metal plate 1, and two or more of them are arranged in parallel in substantially parallel. The four reinforcing members 3 are shown in Fig. 1, but more reinforcing members 3 are actually used. The number of the reinforcing members 3 is divided by, for example, the width b of the short side direction of the rectangular region la of the metal plate 1 partitioned by the first frame members 2a, 2b and the reinforcing member 3 by the thickness to thickness ratio of the thickness t1 of the metal plate 1. b/tl and decided. Here, in order to increase the load of the shear strength as the metal plate 1, in the case where the metal plate 1 is steel, the width to thickness ratio b/tl is preferably 100 or less. Further, in the case where the metal plate 1 is a light metal, the width to thickness ratio b/tl is preferably 60 or less. Further, in order to stabilize the history of the metal plate 1 after the shear is lowered, when the metal plate 1 is steel, the width to thickness ratio b/tl is preferably 50 or less. Further, in the case where the metal plate 1 is a light metal, the width to thickness ratio b/tl is preferably 30 or less. Due to the difference in the Young's modulus of the mild steel material and the light metal material, the width-thickness ratio b/tl of the light metal material is about 60% of the width-thickness ratio b/tl of the mild steel material.
如第1圖所示，異向性補強金屬板100受到剪切應力Q 201043757 時，金屬板1藉由框部2及補強構件3在與金屬板1之面垂直 方向之變形受到限制之狀態下變形。藉此，金屬板1之長方 形區域la以作用於長方形區域la長邊方向之剪切力剪切降 伏。接著，對於金屬板1之長方形區域la短邊方向之剪切 力，補強構件3有助於附加耐力，至達大變形區域之前。 下述數學式1係承受剪切力之正交異向性體平板之平 衡微分方程式。 〔數學式1〕As shown in Fig. 1, when the anisotropic reinforcing metal plate 100 is subjected to the shear stress Q 201043757, the deformation of the metal plate 1 by the frame portion 2 and the reinforcing member 3 in the direction perpendicular to the surface of the metal plate 1 is restricted. Deformation. Thereby, the rectangular area la of the metal plate 1 is sheared and sheared by the shearing force acting in the longitudinal direction of the rectangular area la. Next, with respect to the shearing force in the short-side direction of the rectangular region la of the metal plate 1, the reinforcing member 3 contributes to additional endurance until the large deformation region is reached. The following mathematical formula 1 is a balanced differential equation of an orthogonal anisotropic plate which is subjected to shear force. [Math 1]

The middle term on the left is the sum of the bending stiffness of the Passon's ratio component and the torsional stiffness Dxy. The shear rigidity with respect to the shear force applied to the flat plate is centered on the above-mentioned torsional rigidity. If the Passon's ratio is 0.3, the above-mentioned torsional rigidity accounts for about 70% of the shear rigidity, which is directly related to the shear strength.
如第1圖所示，本實施形態之異向性補強金屬板100， 係以大致平行之狀態等間隔地並列配置複數之補強構件 3。然後，藉由框部2與補強構件3將金屬板1分割成層狀之 複數之長方形區域la。藉此，可提高對於扭轉力矩之金屬 板1之扭轉剛性，即剪切剛性。 即，首先藉由長方形區域la之長邊方向之剪切應力 r，於框部2及補強構件3所包圍之長條狀之長方形區域la

shown in Fig. 1, in the anisotropic reinforcing metal plate 100 of the present embodiment, a plurality of reinforcing members 3 are arranged in parallel at equal intervals in a substantially parallel state. Then, the metal plate 1 is divided into a plurality of rectangular regions la of a layer shape by the frame portion 2 and the reinforcing member 3. Thereby, the torsional rigidity, i.e., shear rigidity, of the metal plate 1 for the torsional moment can be improved. In other words, first, the metal plate 1 is lowered by the long rectangular region la surrounded by the frame portion 2 and the reinforcing member 3 by the shear stress r in the longitudinal direction of the rectangular region la. After that, the shearing of the short side direction of the rectangular area la 9 201043757 Stress: '(4) The member 3 contributes to the intermixing force before the reading of the shaped area. The anisotropic reinforcing metal plate 100, which is an orthogonal anisotropic body, is temporarily limited to the rectangular region la after the shear reduction. At this time, the reinforcing member 3 in parallel or its vicinity is in an elastic state. Therefore, the history of the alternating positive and negative alternating plates can stabilize the history of the anisotropic reinforcing metal plate 100. Therefore, for the increase of the deformation after the shear reduction of the anisotropic reinforcing metal plate, the shear strength can be stably maintained without greatly increasing or decreasing the shearing load. Therefore, according to the anisotropic reinforcing metal plate 100 of the present embodiment, the mechanical stability of the metal plate 1 after shear reduction can be ensured. Fig. 2 is a stress-strain diagram showing the shear stress Q (kN/cm2) on the vertical axis and the strain ε on the horizontal axis. In Fig. 2, the solid line SL1 is a stress-strain diagram of the anisotropic reinforcing metal plate 100 of the present embodiment. The solid line SL2 is a stress-strain diagram in the case where the reinforcing member 3 is not fixed to the surface of the reinforcing metal plate 1 of the metal plate 1. The stress strain line diagram of the case where the dot line DL1 type metal plate 1 only has the frame portion 2. The dotted line DL2 is a strain strain diagram in which only the metal frame portion 2 is provided, and the width b2 of the first frame members 2a and 2b is changed to about 32 mm and the thickness t2 is changed to about 25 mm. As shown by the solid line SL1 in Fig. 2, in the anisotropic reinforcing metal plate 100 of the present embodiment, the shear strength is relatively increased after the shear is lowered. Further, in the case where the anisotropic reinforcing metal plate 100 of the present embodiment is not fixed to the surface of the reinforcing metal plate 1 of the metal plate 1 as shown by the solid line SL2, the endurance starts to decrease earlier. On the other hand, as shown by the dotted line DL1, only the metal plate 1 is reinforced by the frame portion 2, and the frame portion 2 and the anisotropic reinforcing metal plate 100 of the present embodiment have the same size 10 201043757, and a certain degree of endurance can be prevented. reduce. However, if the dotted line dl2k does not, the metal plate 补 is reinforced only by the frame portion 2, and the width of the frame portion 2 is narrower than that of the anisotropic reinforcing metal plate 1 of the present embodiment, so that the corner of the frame portion 2 is 隅The portion is lowered near the center of the metal plate 1, and then the endurance is lowered. Figure 3 shows the metal plate! Stress contour map of the shear force distribution. Figure 3(4) shows the applied shear force. Fig. 3(8) shows a metal plate in the anisotropic reinforcing metal plate of the joint frame portion 2 and the reinforcing member 3, unlike the anisotropic reinforcing metal plate 1 本 本 of the present embodiment! Shear force distribution. The third (4) diagram shows the shear force distribution of the metal plate 丨 of the anisotropic reinforcing metal plate 100 of the present embodiment having the gap between the frame portion 2 and the reinforcing member 3. As shown in Fig. 3(c), there is a gap between the frame portion 2 and the reinforcing member 3, and the shearing force is the same as in the case of Fig. 3(b). Since the shearing force is also generated, the rigidity is high and the plastic deformation starts together, the lodging endurance of the anisotropic reinforcing metal plate 100 is also improved. Therefore, according to the anisotropic reinforcing metal plate of the present embodiment, the rectangular metal plate 1' which is mainly subjected to the shearing force by the frame portion 2 and the reinforcing member 3 can increase the torsional rigidity of the metal plate 1 and cause the metal plate to be twisted. The shear warp load increases. In addition, it can be used to plot the shearing and reversing of the anisotropic _ strong metal plate to endurance stability and 'for thin metal plates can also provide improved plastic deformation ability and for the positive and negative load of the load also has a history of 履 履The shearing plate is sheared. As described above, according to the present embodiment, the shear strength of the anisotropic reinforcing metal plate 100 can be increased as compared with the prior art, and the history of the anisotropic reinforcing metal plate can be made. It is stable. 11 201043757 Further, by making the surface of the reinforcing member 3 in the width b3 direction and the metal plate! facing the width of the contact surface between the metal plate 1 and the reinforcing member 3, the shear rigidity can be increased. 4 and 6 illustrate the second and third embodiments of the present invention.

因此’對於反覆正負交替之剪切力’在使履歷性狀(復 原力特性）成為穩定之紡錘形履歷性狀上，認為如以實線 SL4表示之異向性補強金屬板12〇般，即補強構件23具有第2 部分232之效果較大。 下述數學式2係顯示於剪切翹曲應力度< cr，以寬b、 高度h之矩形平板作為周邊條件單純地支撐、固定支撐之各 關係式。 〔數學式2〕Therefore, it is considered that the shearing force of the alternating positive and negative shearing force is such that the anisotropic reinforcing metal plate 12 is represented by a solid line SL4, that is, the reinforcing member 23 The effect with the second part 232 is greater. The following mathematical expression 2 is shown in the relationship of the shear warpage stress degree < cr, and the rectangular flat plate having the width b and the height h is simply supported and fixedly supported as peripheral conditions.

(5) +5.34 (Expression 2) The wave bracket (the middle bracket) on the right side of the number 2 is the value of the bending rigidity, that is, the bending torsion rigidity accompanying the soft bending of the surface and the torsional rigidity of the flat plate. In the rectangular metal plate, the torsional rigidity is considered to be dominant. Further, after the metal plate is lowered, (4) the deformation is expanded and the bending endurance is aged. Therefore, in the rectangular metal plate, by sufficiently confirming the rigidity of the rotation, it is possible to obtain a stable mechanical property regardless of the ratio of the length of the long side (the length of the side of the long side). Here, the rectangular metal of the second embodiment In the plate u, not only the reinforcing members 13 of the number of 2010 2010 757 are arranged side by side, but the metal plate 11 is divided into the rectangular regions 11 a in the form of a layer, and the second frame members 12 a and 12 b and the second frame member 12 c are provided as the second. In the rectangular metal plate 21 of the third embodiment, not only the plurality of reinforcing members 23 but also a plurality of reinforcing members 23 are arranged side by side, and the metal plates are arranged, and the second and second portions of the rectangular metal plate 21 of the third embodiment are arranged in parallel. 21 is divided into layered rectangular regions 21a, and second portions 22a2 and 22b2 of the first frame members 22a and 22b and second portion 232 of the reinforcing member 23 are provided as orthogonal to the first portion 231 of the reinforcing member 23, as necessary. The second reinforcing member can thereby reinforce the metal plates 11 and 21 to ensure the torsional rigidity, and can form a balance between the oblique tension that expands and expands after the large shear deformation and the force of the truss. In other words, the conspiracy Li Zhiping The anisotropic reinforcing metal plates 110 and 120 are made to have stable mechanical properties in the large deformation region after the slashing and undulating. That is, the reinforcing members 3 and 23 can be changed without depending on the anisotropic reinforcing metal plates 110 and 120. In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. For example, in the second embodiment and the third embodiment. In the embodiment, the first frame member and the second frame member may have the first portion and the second portion. However, the first frame member and the second frame member may not have the second portion. In the third embodiment, the first frame member and the second frame member may not have a flat steel having a rectangular cross-sectional shape in the second portion. Similarly, in the third embodiment, the reinforcing member may not have the first member. The cross-sectional shape of the two parts is a rectangular flat steel. In the second and third embodiments, it is explained that the metal plates are sandwiched between the two faces by the reinforcing members of 2010, 2010, and the reinforcing members are connected by the connecting members. This will make up The case where the strong member is fixed to the metal plate. However, the method of fixing the reinforcing member to the metal plate is not limited thereto, and for example, the reinforcing member may be welded in a dot shape, a line shape or a surface shape or bonded to the metal plate with an adhesive agent. One side or both sides, thereby integrating the reinforcing member with the metal plate.

In particular, when the metal plate surface becomes large like a shear plate of a column type or a shear plate of a wall type, there is a disadvantage that the number of members is increased in the reinforcing structure in which the square metal plate is previously reinforced into a lattice shape. On the other hand, by forming the anisotropic reinforcing structure of the present invention, the entire structure can be simplified, and various metal materials can be easily used as the metal plate subjected to the shearing force. Further, as described in the above embodiment, the metal plate is held by the reinforcing member and fixed by the connecting member, and a thinner metal plate can be used, and the weight and the low cost of the shearing plate can be increased. The possibility of transformation. Further, in the above-described embodiment, the spot joint is, for example, spot welded or bolted. The so-called linear joint side is, for example, fillet welding or butt joint, and the surface joint is joined by, for example, an adhesive. In all of the above embodiments, the non-adhesive material U may be applied or attached between the stencil 1 and the reinforcing member 3. There is a non-adhesive material between the components, and the shear stress of the metal plate 1 is the same as that of the mandrel, and the shoulders are sturdy, and the low-cycle fatigue strength is also improved.
