Description
本發明是關於疊層橡膠體用接合構件及使用該接合構件之疊層橡膠體以及構造體，是使用於建築構造體的免震構造。The present invention relates to a joint member for a laminated rubber body, a laminated rubber body and a structure using the joint member, and is a vibration-proof structure used for a building structure.
建築構造體及土木構造體的支承安裝構造，尤其是使用於建築構造體的免震構造的疊層橡膠體、使用於土木構造體的免震構造及水平力分散構造的疊層橡膠體，在該疊層橡膠體的構造上，在壓縮方向具有很大的耐力，能支撐上部構造體的荷重，可是拉伸方向的耐力是較差於壓縮方向的耐力。The supporting structure of the building structure and the civil structure, in particular, the laminated rubber body used for the seismic isolation structure of the building structure, the vibration-proof structure used for the civil structure, and the laminated rubber body of the horizontal force dispersion structure, The laminated rubber body has a large resistance in the compression direction and can support the load of the upper structure, but the endurance in the tensile direction is inferior to the compression direction.
因此，作為免震裝置的疊層橡膠體的開發初期階段，為了不使拉伸力作用於疊層橡膠體，防止藉由該拉伸力導致疊層橡膠體的損傷或斷裂，而利用定縫銷釘(dowelpin)的連結來進行疊層橡膠體與上部及下部構造體的安裝，讓設計者解決上下方向的拉伸力的課題。Therefore, in the initial stage of development of the laminated rubber body as the vibration-proof device, in order to prevent the tensile rubber from acting on the laminated rubber body, it is possible to prevent the damage or breakage of the laminated rubber body by the tensile force, and to use the slit. The connection of the dowel pins to attach the laminated rubber body to the upper and lower structures allows the designer to solve the problem of the tensile force in the vertical direction.
該安裝構造，如12圖所示，將疊層橡膠體64的凸緣板66、67，使用安裝螺栓62與空心螺母63固定在：在構造體61的地基等的下部構造體69處所固定的錨板65、及在上部構造體70處固定的上部板68，當有大幅度的水平變形作用於疊層橡膠體64時，藉由疊層橡膠體64的上面64a與下面64b的水平方向的相對偏移，在疊層橡膠體64產生旋轉力矩，在疊層橡膠體64的安裝構造部分產生鉛直方向的拉拔力。可是，藉由疊層橡膠體64、與突出設置於凸緣板66、67的定縫銷釘71分離，則可將拉拔力解放，即使是很大地震所引起的大幅度水平變形，也不會有過大的拉伸力作用在疊層橡膠體64的鉛直方向。因此，可防止疊層橡膠體64的損傷或破損，並且，不會有過大的力量作用在上部構造體70與疊層橡膠體64安裝的部分，所以有能防止上部構造體70損傷的效果。In the mounting structure, as shown in Fig. 12, the flange plates 66 and 67 of the laminated rubber body 64 are fixed to the lower structure 69 such as the foundation of the structure 61 by using the mounting bolt 62 and the hollow nut 63. The anchor plate 65 and the upper plate 68 fixed at the upper structure 70 are horizontally oriented by the upper surface 64a and the lower surface 64b of the laminated rubber body 64 when a large horizontal deformation acts on the laminated rubber body 64. With respect to the relative offset, a rotational moment is generated in the laminated rubber body 64, and a pulling force in the vertical direction is generated in the mounting structure portion of the laminated rubber body 64. However, since the laminated rubber body 64 is separated from the fixed pin 71 projecting from the flange plates 66 and 67, the pulling force can be released, even if it is a large horizontal deformation caused by a large earthquake, Excessive tensile force acts on the vertical direction of the laminated rubber body 64. Therefore, damage or breakage of the laminated rubber body 64 can be prevented, and an excessive force is not applied to the portion where the upper structure body 70 and the laminated rubber body 64 are attached. Therefore, the upper structure 70 can be prevented from being damaged.
可是，如果利用上述定縫銷釘式的接合方法，雖然在大幅度水平變形時，定縫銷釘部分分離，鉛直方向的拉伸力不會作用於支承安裝構造部分，而如果分離的程度變得更大的話，則可能定縫銷釘會脫離，疊層橡膠體本身產生變形。如果變成這種狀態，則疊層橡膠體的水平阻力會降低，疊層橡膠體也有翻轉的危險性，在採用定縫銷釘的安裝構造的情況，將產生水平力降低的變形量作為翻轉極限(滾出移位)，而必須界定疊層橡膠體的使用界限(例如，參考非專利文獻1)。However, if the above-mentioned fixed-pin type joining method is used, although the fixed-pin pin is partially separated at a large horizontal deformation, the tensile force in the vertical direction does not act on the support mounting structure portion, and if the degree of separation becomes more If it is large, it may be that the dowel pin will be detached, and the laminated rubber body itself is deformed. If this state is reached, the horizontal resistance of the laminated rubber body is lowered, and the laminated rubber body is also likely to be reversed. In the case of the mounting structure of the fixed pin, the amount of deformation in which the horizontal force is reduced is taken as the inversion limit ( It is necessary to define the use limit of the laminated rubber body (for example, refer to Non-Patent Document 1).
因此，在疊層橡膠體與上部及下部構造體的連結，一般來說，是廣泛使用：可不考慮之前的翻轉極限的利用安裝螺栓的緊固手段，疊層橡膠體的設計者，非常了解疊層橡膠體的拉伸方向的耐力較低，除了藉由很多實驗驗證來掌握其特性之外，且在疊層橡膠體不會產生拉伸力，或即使產生也有考慮拉伸方向的承受度，在確保高安全率的狀態下進行設計。Therefore, the connection between the laminated rubber body and the upper and lower structures is generally widely used: the fastening means using the mounting bolts can be used regardless of the previous inversion limit, and the designer of the laminated rubber body is well aware of the stack. The tensile strength of the layer rubber body is low, except that the characteristics are grasped by many experimental tests, and the tensile rubber force is not generated in the laminated rubber body, or the tensile direction is considered even if it is generated. Designed while ensuring a high safety rate.
可是，近年來，建築構造體的免震設計，進展到對高層建築物的適用、或對高寬比較大的建築構造體的適用，伴隨著，進行具有高拉伸能力的疊層橡膠體的開發、或為了使鉛直方向的超過承受度的拉伸力不傳達到疊層橡膠體，而在上部構造體與地盤之間設置有浮起防止裝置的設計。However, in recent years, the seismic design of building structures has progressed to the application to high-rise buildings, or to the construction of taller and wider building structures, accompanied by the lamination of rubber bodies with high tensile strength. The development or the stretching force exceeding the tolerance in the vertical direction is not transmitted to the laminated rubber body, and a floating prevention device is provided between the upper structure and the ground.
並且，除了配置在上部構造體與地盤之間的浮起防止裝置的設計以外，為了使較大的拉伸力不傳達到疊層橡膠體，而針對疊層橡膠體與上部及下部構造體的連結方法進行各種研究。Further, in addition to the design of the floating prevention device disposed between the upper structure and the ground, in order to prevent a large tensile force from being transmitted to the laminated rubber body, the laminated rubber body and the upper and lower structures are The connection method is used for various studies.
如果採用藉由螺栓將疊層橡膠體緊固於上部構造體或下部構造體的連結構造的話，則在有大幅度水平變形產生於疊層橡膠體的情況，旋轉力矩導致鉛直方向的拉伸力作用於疊層橡膠體，會有讓疊層橡膠體損傷或破損、朝上部構造體或下部構造體的過大的力量導致構造體受損的可能性，並且，在高寬比較大的建築構造體，會有因為地震時的震盪導致過大的拉伸力作用於疊層橡膠體的可能性。另一方面，如果為了避免鉛直方向的拉伸力而採用定縫銷釘式的連結構造的話，則會有翻轉極限的限制，不管是螺栓的連結構造或定縫銷釘式的連結構造，在選擇疊層橡膠體的連結方法上都不是令人滿意的構造。When the connection structure in which the laminated rubber body is fastened to the upper structure or the lower structure by bolts is used, when a large amount of horizontal deformation occurs in the laminated rubber body, the rotational moment causes a tensile force in the vertical direction. When the laminated rubber body is applied, the laminated rubber body may be damaged or damaged, and the structure may be damaged by excessive force toward the upper structure or the lower structure, and the building structure having a relatively high width and width may be used. There is a possibility that an excessive tensile force acts on the laminated rubber body due to the shock during the earthquake. On the other hand, if a fixed-pin type connection structure is used in order to avoid the tensile force in the vertical direction, there is a limit of the inversion limit, regardless of the bolt connection structure or the fixed-pin type connection structure. The joining method of the layer rubber body is not a satisfactory structure.
因此，例如，在專利文獻1的技術揭示有：具備有：在疊層橡膠免震支承裝置的其中一方的端面處固定的其中一方的安裝板(凸緣板)、以及在較疊層橡膠免震支承裝置的其中一方的端面的外緣更外側與其中一方的安裝板固定，並且在較固定於該其中一方的安裝板的部分更內側，在與疊層橡膠免震裝置的其中一方的端面相面對的地基或構造體的安裝面處固定的另一方的安裝板：在上部構造體與下部構造體之間產生浮起時，能讓兩安裝板的相互的固定部位朝上方移動，能利用安裝板的彎曲剛性，所以較大的鉛直方向的拉伸力不會朝疊層橡膠免震支承裝置作用。Therefore, for example, the technique of Patent Document 1 discloses that one of the mounting plates (flange plates) which is fixed at one of the end faces of the laminated rubber vibration-isolating support device, and the laminated rubber are provided. The outer edge of one end surface of the shock supporting device is fixed to the outer side of one of the mounting plates, and is further inside the portion of the mounting plate that is fixed to the one side, and is at one end of the laminated rubber vibration isolating device. The other mounting plate fixed at the mounting surface of the facing surface or the structural body: when the floating between the upper structural body and the lower structural body occurs, the mutual fixing portions of the two mounting plates can be moved upward, and With the bending rigidity of the mounting plate, the large vertical tensile force does not act toward the laminated rubber vibration-isolating support device.
在專利文獻2的技術揭示有：在疊層橡膠部的外周與對構造構件的固定部之間的部分，形成有：用來使凸緣構件的彎曲剛性降低的薄片部或開口部，即使拉拔力作用於疊層橡膠體，也能防止疊層橡膠體損傷。The technique of Patent Document 2 discloses that a portion between the outer circumference of the laminated rubber portion and the fixing portion of the structural member is formed with a sheet portion or an opening portion for reducing the bending rigidity of the flange member, even if the sheet is opened. The pulling force acts on the laminated rubber body to prevent damage to the laminated rubber body.
在專利文獻3的技術揭示有：將隔離器與構造體的緊固，經由緩衝座例如經由盤簧以螺栓緊固，對於水平動作則緊緊地旋緊，對於上下動作則經由緩衝座彈性地旋緊。The technique of Patent Document 3 discloses that the fastening of the separator and the structure is fastened by bolts via a buffer holder, for example, via a coil spring, and is tightly tightened for a horizontal operation, and elastically for a vertical movement via a cushion seat. Tighten tightly.
在專利文獻4的技術揭示有：在疊層橡膠的凸緣部、與將主體緊固的螺栓的頭部之間，中介著橡膠薄片等的緩衝材的免震裝置的拉拔對應機構，作為緩衝材是由環狀的鋼板與橡膠薄片等所構成，緩衝材可朝厚度方向變形，即使在地震時施加瞬間的浮起力，藉由緩衝材的變形或破壞來吸收力量，讓拉伸力不會施加在疊層橡膠。The technique of the patent document 4 discloses a drawing-removing mechanism of a vibration-damping device in which a cushioning material such as a rubber sheet is interposed between a flange portion of a laminated rubber and a head of a bolt that fastens the main body. The cushioning material is composed of a ring-shaped steel plate, a rubber sheet, or the like, and the cushioning material can be deformed in the thickness direction, and even if an instantaneous floating force is applied during an earthquake, the force is absorbed by the deformation or destruction of the cushioning material, and the tensile force is applied. Will not be applied to the laminated rubber.
在專利文獻5的技術揭示有上下動作免震體，其將疊層橡膠體配置成相對於上下方向的震動，於疊層橡膠體的剪力方向朝鉛直方向作用，雖然欲解決的課題不同，而在次要性地在上部構造體朝上方向浮起時，上下方向的拉伸力不會作用於：在水平方向剪斷的水平動作免震體的安裝螺栓、及構成水平動作免震體的疊層橡膠體的疊層橡膠部分。According to the technique of the patent document 5, the up-and-down motion vibration-dissipating body is disposed, and the laminated rubber body is disposed in a vertical direction in the shear direction of the laminated rubber body with respect to the vibration in the vertical direction, and the problem to be solved is different. When the upper structure is floated upward in a secondary manner, the tensile force in the vertical direction does not act on the mounting bolts of the horizontally movable vibration-damping body that is sheared in the horizontal direction, and the horizontal motion-free vibration-damping body. The laminated rubber portion of the laminated rubber body.

可是，如專利文獻1藉由將疊層橡膠體的安裝板作成雙重構造，或如專利文獻2藉由對凸緣加工以使疊層橡膠體的凸緣構件的彎曲剛性降低，來減低對疊層橡膠體的拉伸力的手段，是伴隨著疊層橡膠體的構造本體的設計變更，而耗費費用與時間，也必須重新設計安裝空間，並不能簡單地適用。However, as in Patent Document 1, the mounting plate of the laminated rubber body is double-structured, or as in Patent Document 2, the flange is machined to reduce the bending rigidity of the flange member of the laminated rubber body, thereby reducing the folding. The means for drawing the tensile force of the rubber body is a design change of the structural body of the laminated rubber body, which is costly and time consuming, and the installation space must be redesigned, and cannot be simply applied.
在該方面，專利文獻3、專利文獻4這樣的在疊層橡膠體的安裝部分隔介著緩衝材的技術，雖然可減低浮起造成朝疊層橡膠的拉伸力，並且也能對應於藉由疊層橡膠體的大幅度水平變形所產生的拉拔力的緩和，而如專利文獻3將由鋼材所構成的盤簧組合時，鋼材的接觸部或產生彈性變形的部分會有防鏽的問題，在如專利文獻4使用由環狀的鋼板與橡膠薄片等所構成的作為緩衝材的筒狀的橡膠墊片的情況，是利用橡膠材料的壓縮特性的只是圓筒狀的型態，所以在壓縮時橡膠材料朝筒狀內徑方向膨脹，產生與安裝螺栓的緩衝，而可能會讓由筒狀橡膠墊片所構成的緩衝材破損。In this respect, in the technique of interposing the cushioning material in the mounting portion of the laminated rubber body as disclosed in Patent Document 3 and Patent Document 4, the tensile force against the laminated rubber can be reduced, and the corresponding force can be borrowed. When the pull-out force generated by the large-scale horizontal deformation of the laminated rubber body is alleviated, when the coil spring composed of the steel material is combined in Patent Document 3, the contact portion of the steel material or the portion which is elastically deformed may have a problem of rust prevention. In the case of using a cylindrical rubber gasket as a cushioning material composed of a ring-shaped steel sheet and a rubber sheet, as in Patent Document 4, the compression property of the rubber material is only a cylindrical shape, so The rubber material expands toward the inner diameter of the cylinder during compression, causing cushioning with the mounting bolts, which may damage the cushioning material composed of the cylindrical rubber gasket.
本發明，鑑於這種情形，其目的要提供一種接合構件、具備該接合構件的疊層橡膠體、及藉由該疊層橡膠體所支撐的構造體，不用隨著變更體積大的疊層橡膠體的安裝部分的形狀，即使高寬比較大的免震建築構造體等其上部構造體產生浮起的情況，也能吸收該浮起量，並且使對於疊層橡膠體的彈性層或黏接層的鉛直方向的拉伸力減低，且能防止疊層橡膠體的破損或損傷。The present invention has been made in view of such circumstances, and an object thereof is to provide a joining member, a laminated rubber body including the joining member, and a structure supported by the laminated rubber body, and it is not necessary to change the bulk rubber with a large volume. The shape of the mounting portion of the body can absorb the floating amount even if the upper structure of the shock-free building structure having a relatively large width and a large width is lifted, and the elastic layer or the bonding layer for the laminated rubber body is adhered. The tensile strength of the layer in the vertical direction is reduced, and the damage or damage of the laminated rubber body can be prevented.
為了達成上述目的，本發明，是疊層橡膠體用接合構件，疊層橡膠體形成為：在交互疊層著由橡膠材料構成的彈性層與補強板的疊層橡膠部的各上下端面，接合著凸緣板；將該疊層橡膠體，以允許該疊層橡膠體與上述構造體的鉛直方向的分離也就是所謂的浮起的方式，隔介著該凸緣板接合於上部構造體或/及下部構造體，其特徵為：是由彈性構件所構成，該彈性構件，其中一側，是以藉由剪力變形來追隨上述上側凸緣板或/及下側凸緣板的鉛直方向的分離的方式，與該凸緣板接合，另一側，不移動地固定在：於上述上部構造體或/及下部構造體處固定的上側錨板或/及下側錨板側。In order to achieve the above object, the present invention is a joint member for a laminated rubber body, and the laminated rubber body is formed by laminating the upper and lower end faces of the laminated rubber portion in which the elastic layer made of a rubber material and the reinforcing plate are alternately laminated. a flanged plate; the laminated rubber body is joined to the upper structure by means of the flange plate so as to allow separation of the laminated rubber body from the vertical direction of the structure, that is, a so-called floating manner And a lower structure, which is characterized in that it is composed of an elastic member, wherein one side of the elastic member follows the vertical direction of the upper flange plate or/and the lower flange plate by shear deformation. The separation means is joined to the flange plate, and the other side is fixed to the upper anchor plate or/and the lower anchor plate side fixed to the upper structure or/and the lower structure.
藉由本發明，在高寬比較大的免震建築構造體等，因為震盪而上部構造體產生浮起，拉伸力朝鉛直方向作用於疊層橡膠體安裝部，在疊層橡膠體的凸緣板與作為下部構造體的錨板等之間，朝鉛直方向產生浮起時，由於該接合構件可在鉛直方向產生剪力變形，所以除了可吸收在鉛直方向產生的移位之外，不會有過大的應力作用於疊層橡膠體，而能防止疊層橡膠體的破損或損傷。According to the present invention, in the seismic isolation building structure having a relatively large height and a large width, the upper structure body is floated due to the oscillation, and the tensile force acts on the laminated rubber body mounting portion in the vertical direction, and the flange of the laminated rubber body is applied. When the plate is floated in the vertical direction between the plate and the anchor plate or the like as the lower structure, since the joint member can be shear-deformed in the vertical direction, it does not absorb the displacement in the vertical direction. Excessive stress acts on the laminated rubber body to prevent breakage or damage of the laminated rubber body.
在上述疊層橡膠體用接合構件，將上述彈性構件作為剪力型筒狀橡膠體，插入於：在上述上側或/及下側凸緣板處穿設的安裝螺栓孔，將該剪力型筒狀橡膠體的其中一側也就是外周面側接合於上述凸緣板，將該剪力型筒狀橡膠體的另一側也就是內周面側，隔介著插通於該剪力型筒狀橡膠體的安裝用螺栓，不移動地固定於上述上側或/及下側錨板側。藉此，例如當下側凸緣板浮起時，筒狀橡膠體的外周面側朝上方移動，內周面藉由安裝螺栓而不移動地被固定在作為下部構造體的下側錨板等，所以筒狀橡膠產生剪力變形，吸收朝上方的浮起力，且能防止較大的拉伸力作用於疊層橡膠體的彈性層、黏接層。In the above-described laminated rubber body joining member, the elastic member is inserted as a shear-type tubular rubber body into a mounting bolt hole that is bored in the upper side or/and the lower flange plate, and the shearing type is used. One side of the tubular rubber body, that is, the outer peripheral surface side, is joined to the flange plate, and the other side of the shear-type tubular rubber body is the inner peripheral surface side, and is inserted through the shear force type. The bolt for mounting the tubular rubber body is fixed to the upper side or/and the lower anchor plate side without being moved. With this, for example, when the lower flange plate is floated, the outer peripheral surface side of the tubular rubber body moves upward, and the inner peripheral surface is fixed to the lower anchor plate or the like as the lower structure by the mounting bolt without being moved. Therefore, the tubular rubber generates shear deformation, absorbs the upward floating force, and prevents a large tensile force from acting on the elastic layer and the adhesive layer of the laminated rubber body.
在上述疊層橡膠體用接合構件，可將上述剪力型筒狀橡膠體作成：內周面及外周面由筒狀鋼材所構成，並且在內周面與外周面之間配置至少一個筒狀鋼材，在各筒狀鋼材之間配置圓筒狀橡膠，鄰接的筒狀鋼材及圓筒狀橡膠各互相硫化黏接而作成剖面觀察為同心圓狀的疊層橡膠形狀。In the above-described laminated rubber body joining member, the shearing-type tubular rubber body can be formed such that the inner peripheral surface and the outer peripheral surface are formed of a cylindrical steel material, and at least one cylindrical shape is disposed between the inner peripheral surface and the outer peripheral surface. In the steel material, a cylindrical rubber is placed between the respective tubular steel materials, and the adjacent cylindrical steel materials and the cylindrical rubber are vulcanized and bonded to each other to form a laminated rubber shape which is concentrically observed in cross section.

將上述剪力型筒狀橡膠體的內周面側的筒狀鋼材，朝上述上側或/及下側凸緣板從上述上側或/及下側錨板分離的方向，延伸設置有確保上述疊層橡膠體的預定的浮起量的長度；將上述剪力型筒狀橡膠體的外周面側筒狀鋼材的從上述上側或/及下側錨板分離的方向的端部，朝外周側擴徑成與上述上側或/及下側凸緣板卡合，而設置凸緣部。The cylindrical steel material on the inner circumferential surface side of the shear-type cylindrical rubber body is extended in a direction separating the upper side or/and the lower side flange plate from the upper side or/and the lower side anchor plate to secure the stack. The length of the predetermined amount of floating of the layer rubber body; the end portion of the outer peripheral surface side tubular steel material of the shearing type cylindrical rubber body separated from the upper side or the lower side anchor plate is expanded toward the outer peripheral side The flange is engaged with the upper side or/and the lower flange plate, and a flange portion is provided.
在上述剪力型筒狀橡膠體的內周面側的筒狀鋼材與上述安裝螺栓的膨脹部之間，配置有：具有用來確保上述疊層橡膠體的預定的浮起量的高度量的圓筒狀構件，將上述剪力型筒狀橡膠體的外周面側筒狀鋼材的從上述上側或/及下側錨板分離的方向的端部，朝外周側擴徑成與上述上側或/及下側凸緣板卡合，而設置凸緣部。Between the cylindrical steel material on the inner circumferential surface side of the shear-type cylindrical rubber body and the expansion portion of the mounting bolt, a height amount for ensuring a predetermined floating amount of the laminated rubber body is disposed. In the cylindrical member, the end portion of the outer peripheral surface side tubular steel material of the shear-type cylindrical rubber body in the direction separating from the upper side or the lower side anchor plate is expanded toward the outer peripheral side to the upper side or The lower flange plate is engaged with the flange portion.
在上述疊層橡膠體用接合構件，在上述剪力型筒狀橡膠體與上述安裝螺栓之間，能配置有用來限制該剪力型筒狀橡膠體的變形的擋塊。藉此，當在接合構件產生超過預定設定量的大浮起量時，可以將接合構件的圓筒狀橡膠的剪力變形量控制在安全的範圍，而能防止筒狀橡膠破損。In the above-described laminated rubber body joining member, a stopper for restricting deformation of the shear-type tubular rubber body can be disposed between the shear-type tubular rubber body and the mounting bolt. Thereby, when a large floating amount exceeding a predetermined set amount is generated in the joint member, the amount of shear deformation of the cylindrical rubber of the joint member can be controlled to a safe range, and the tubular rubber can be prevented from being damaged.
本發明，是疊層橡膠體，具備有上述任一種疊層橡膠體用接合構件。藉此，如上述，不會使過大的拉伸力作用於疊層橡膠體，過大的拉伸力也不會作用於疊層橡膠體與構造體的固定部分，所以可以使疊層橡膠體及免震構造體的安全性提升。The present invention is a laminated rubber body comprising the above-described joining member for a laminated rubber body. Therefore, as described above, the excessive stretching force is not applied to the laminated rubber body, and the excessive tensile force does not act on the fixed portion of the laminated rubber body and the structure, so that the laminated rubber body can be prevented. The safety of the seismic structure is improved.

The partial shape can absorb the floating amount even if the building structure or the like having a relatively large width or the like is lifted, and the damage or damage of the laminated rubber body can be prevented.
接著，針對用來實施本發明的方式，參考圖面來詳細說明。Next, the manner in which the present invention is implemented will be described in detail with reference to the drawings.

疊層橡膠體7是形成為：在交互疊層著橡膠層6a與補強板6b的疊層橡膠部6的上下端面各接合著凸緣板3(3A、3B)，橡膠層6a與補強板6b及橡膠層6a與凸緣板3的接觸面，是藉由硫化黏接而形成為一體。在疊層橡膠部6的貫穿孔，封入著圓柱狀的鉛插銷6c，以兩枚蓋板6d封住。The laminated rubber body 7 is formed by joining flange plates 3 (3A, 3B) to the upper and lower end faces of the laminated rubber portion 6 on which the rubber layer 6a and the reinforcing plate 6b are alternately laminated, and the rubber layer 6a and the reinforcing plate 6b. The contact surface of the rubber layer 6a and the flange plate 3 is integrally formed by vulcanization bonding. A cylindrical lead pin 6c is sealed in the through hole of the laminated rubber portion 6, and is sealed by two cover plates 6d.
在上部構造體8的下面，隔介著附頭柱狀螺栓11B而固定著上側錨板4B，在下部構造體9的上面，隔介著附頭柱狀螺栓11A而固定著下側錨板4A，在疊層橡膠體7的凸緣板3的延伸部安裝著接合構件1(1A、1B)。On the lower surface of the upper structure 8, the upper anchor plate 4B is fixed via the attachment stud bolt 11B, and the lower anchor plate 4A is fixed to the upper surface of the lower structure body 9 via the attachment stud bolt 11A. The joining member 1 (1A, 1B) is attached to the extending portion of the flange plate 3 of the laminated rubber body 7.
如第1圖及第2圖所示，接合構件1，是以：形成為剪力型筒形橡膠體，具有插通孔1a'的內周面側圓筒狀鋼材1a、具有凸緣部1e'的外周面側圓筒狀鋼材1e、中間圓筒狀鋼材1c、以及各中介安裝在該圓筒狀鋼材1a、1c、1e之間的圓筒狀橡膠1b、1d所構成，鄰接的圓筒狀鋼材與圓筒狀橡膠是互相藉由黏接劑堅固地黏接著，作成使用於疊層橡膠部6等的硫化黏接較佳。藉此，將接合構件1形成為從剖面方向觀察為同心圓狀的疊層橡膠形狀。 As shown in Fig. 1 and Fig. 2, the joint member 1 is formed of a shear-type cylindrical rubber body, and has an inner peripheral surface side cylindrical steel material 1a having an insertion hole 1a' and a flange portion 1e. The outer peripheral surface side cylindrical steel material 1e, the intermediate cylindrical steel material 1c, and the cylindrical rubbers 1b and 1d each interposed between the cylindrical steel materials 1a, 1c, and 1e, and adjacent cylinders The steel material and the cylindrical rubber are firmly adhered to each other by an adhesive, and it is preferable to use the vulcanization bonding for the laminated rubber portion 6 or the like. Thereby, the joining member 1 is formed in a laminated rubber shape which is concentrically viewed from the cross-sectional direction.
上述圓筒狀鋼材1a、1c、1e，是通常使用在疊層橡膠體的一般構造用軋製鋼板，也可使用將熱軋軟鋼板或冷軋鋼板以預定直徑的大小彎曲成形為圓筒狀的圓筒狀鋼板，也可使用預先成形為碳鋼鋼板等的圓筒狀的圓筒狀鋼板。並且，也可取代這些由鋼構成的材料，只要是由剪力型筒狀橡膠所構成的接合構件所需要，只要是合乎：朝圓筒狀的軸方向的剪力變形功能以及圓筒狀外周面方向的壓縮變形功能的範圍，則也可使用合成樹脂、鋁等的非金屬材料。 The cylindrical steel materials 1a, 1c, and 1e are generally used for a rolled steel sheet for a general structure of a laminated rubber body, and a hot rolled soft steel sheet or a cold rolled steel sheet may be bent into a cylindrical shape with a predetermined diameter. As the cylindrical steel sheet, a cylindrical cylindrical steel sheet which has been previously formed into a carbon steel sheet or the like can be used. Further, in place of these materials made of steel, as long as it is required for a joint member made of a shear-type tubular rubber, it is suitable for a shear deformation function in a cylindrical axial direction and a cylindrical outer circumference. For the range of the compression deformation function in the plane direction, a non-metallic material such as synthetic resin or aluminum may be used.
使用於圓筒狀橡膠1b、1d的橡膠的材料，除了機械特性優異之外，隨時間變化較小，且耐水性、耐臭氧性等的環境特性較佳的材料較好，可以是天然橡膠或合成橡膠的材料，也可是將天然橡膠與合成橡膠混合成的橡膠材料。 The material of the rubber used for the cylindrical rubbers 1b and 1d is excellent in mechanical properties except for being excellent in mechanical properties, and is preferably a natural rubber or a material having better environmental characteristics such as water resistance and ozone resistance.

The hollow nut 5 has a large diameter portion 5a and a small diameter portion 5b, and has a female screw portion 5c that is open to the upper surface of the small diameter portion 5b.
接合構件1的安裝，如第2圖所示，在錨板4的貫穿孔4a收容著空心螺母5的小徑部5b，在凸緣板3的貫穿孔3a收容著接合構件1，如第1圖所示，使接合構件1的外周面側圓筒狀鋼材1e的凸緣部1e'抵接於凸緣板3的上 面，將凸緣板3與錨板4重疊，將安裝螺栓2插通於接合構件1的插通孔1a'，然後將安裝螺栓2的公螺紋部2b與空心螺母5的母螺紋部5c螺合。藉此，則接合構件1的內周面側圓筒狀鋼材1a，會被安裝螺栓2的膨脹部2a與空心螺母5的小徑部5b堅固地夾持住，不移動地固定在錨板4。另一方面，將接合構件1的外周面側圓筒狀鋼材1e的凸緣部1e'接合於凸緣板3的上面。 As shown in Fig. 2, the small-diameter portion 5b of the hollow nut 5 is housed in the through hole 4a of the anchor plate 4, and the joint member 1 is housed in the through hole 3a of the flange plate 3 as shown in Fig. 2, as shown in Fig. 2 As shown in the figure, the flange portion 1e' of the outer peripheral surface side cylindrical steel material 1e of the joint member 1 abuts on the flange plate 3 The flange plate 3 is overlapped with the anchor plate 4, the mounting bolt 2 is inserted into the insertion hole 1a' of the joint member 1, and then the male screw portion 2b of the mounting bolt 2 and the female screw portion 5c of the hollow nut 5 are screwed. Hehe. As a result, the inner circumferential surface side cylindrical steel material 1a of the joint member 1 is firmly held by the expansion portion 2a of the mounting bolt 2 and the small diameter portion 5b of the hollow nut 5, and is fixed to the anchor plate 4 without being moved. . On the other hand, the flange portion 1e' of the outer peripheral surface side cylindrical steel material 1e of the joining member 1 is joined to the upper surface of the flange plate 3.
上述接合構件1，如第3圖所示，在下側凸緣板3A與下側錨板4A之間，各中介安裝於疊層橡膠體7的複數安裝螺栓2A，並且在上側凸緣板3B與上側錨板4B之間，以與上述同樣的方式各中介安裝於疊層橡膠體7的複數安裝螺栓2B。 As shown in Fig. 3, the joint member 1 is interposed between the lower flange plate 3A and the lower anchor plate 4A, and is interposed between the plurality of mounting bolts 2A of the laminated rubber body 7, and the upper flange plate 3B. Between the upper anchor plates 4B, the plurality of mounting bolts 2B of the laminated rubber body 7 are interposed in the same manner as described above.
接著，針對具有上述構造的接合構件1的動作，主要參考第3圖及第4圖來說明。 Next, the operation of the joint member 1 having the above-described structure will be mainly described with reference to FIGS. 3 and 4 .
當地震時等，在構造體13的上部構造體8藉由震盪等產生浮起，拉伸力朝鉛直方向作用於疊層橡膠體7的安裝部時，具體來說，如第4圖所示，即使在疊層橡膠體7的凸緣板3、與固定在下部構造體9的錨板4之間產生鉛直方向的浮起，形成為疊層橡膠形狀的接合構件1的內周面側圓筒狀鋼材1a仍是不移動地固定於錨板4，並且外周面側圓筒狀鋼材1e的凸緣部1e'是接合於凸緣板3的上面，所以接合構件1能朝鉛直方向產生剪力變形，而將疊層橡膠體7朝上方的浮起予以吸收，可防止較大的拉伸力產生於疊層橡膠體7的彈性層、黏接層等，而可防止疊層橡膠體7的損傷或斷裂。When an earthquake or the like occurs, the upper structure 8 of the structure 13 is lifted by vibration or the like, and the tensile force acts on the mounting portion of the laminated rubber body 7 in the vertical direction, specifically, as shown in FIG. Even if the flange plate 3 of the laminated rubber body 7 and the anchor plate 4 fixed to the lower structure body 9 are floated in the vertical direction, the inner peripheral surface side of the joint member 1 formed in a laminated rubber shape is rounded. The tubular steel material 1a is fixed to the anchor plate 4 without being moved, and the flange portion 1e' of the outer peripheral surface side cylindrical steel material 1e is joined to the upper surface of the flange plate 3, so that the joint member 1 can be sheared in the vertical direction. The force is deformed, and the laminated rubber body 7 is absorbed upward to prevent the large tensile force from being generated in the elastic layer, the adhesive layer, and the like of the laminated rubber body 7, and the laminated rubber body 7 can be prevented. Damage or breakage.
藉由使用具有上述從剖面方向觀察為同心圓狀的筒狀疊層橡膠構造的接合構件1，則朝剪力方向，換言之，朝凸緣板3的浮起方向的變形容易進行，而在與接合構件1的剪力方向正交的方向，也就是從疊層為同心圓狀的構件的外周面朝中心軸方向的變形(所謂的壓縮變形)，換言之，在用來支承構造體13的疊層橡膠體7的水平方向的力的傳達，是具有很大的剛性，所以雖然產生些許壓縮變形，可是與習知的安裝螺栓所造成的力量傳達狀況比較起來，可以不用特別考慮地加以使用。By using the joint member 1 having the tubular laminated rubber structure which is concentrically viewed from the cross-sectional direction, the deformation in the direction of the shear force, in other words, the direction of the flange plate 3 in the floating direction is facilitated, and The direction in which the shearing direction of the joining member 1 is orthogonal, that is, the deformation from the outer peripheral surface of the member which is concentrically joined toward the central axis (so-called compression deformation), in other words, the stack for supporting the structural body 13 The horizontal force of the layer rubber body 7 is transmitted with great rigidity. Therefore, although a slight compression deformation occurs, it can be used without special consideration as compared with the force transmission state by a conventional mounting bolt.
並且藉由將由剪力型筒狀橡膠所構成的接合構件1，各配置於疊層橡膠體7的安裝螺栓，則藉由作用於疊層橡膠體7的水平力，從接合構件1的同心圓狀的筒狀疊層橡膠的外周面朝中心方向作用時所產生的些微的變形，可以防止集中在特定的安裝螺栓，也可避免在習知方式的各個安裝螺栓的分別壞掉的可能性。Further, by arranging the joint members 1 made of the shear-type tubular rubber in the mounting bolts of the laminated rubber body 7, the horizontal force acting on the laminated rubber body 7 is from the concentric circles of the joint members 1. The slight deformation caused when the outer peripheral surface of the cylindrical laminated rubber acts in the center direction can be prevented from being concentrated on a specific mounting bolt, and the possibility that the respective mounting bolts of the conventional method are broken can be avoided.
凸緣板3的浮起現象，即使藉由配置於上部構造體8與下部構造體9之間的疊層橡膠體7的水平剪力變形所伴隨的翻轉現象(滾出現象)、或藉由上部構造體8的震盪現象導致的浮起，而不是垂直於安裝螺栓2的軸線而與軸線具有角度的情況，在接合構件1的圓筒狀橡膠1b、1d產生彎曲變形，對於凸緣板3的浮起，不會產生成為很大阻力的嚙合或摩擦。The floating phenomenon of the flange plate 3 is caused by the inversion phenomenon (rolling appearance) accompanying the horizontal shear deformation of the laminated rubber body 7 disposed between the upper structure body 8 and the lower structure body 9, or by The floating of the upper structure 8 caused by the oscillating phenomenon, rather than the angle perpendicular to the axis of the mounting bolt 2, is caused by bending deformation of the cylindrical rubbers 1b, 1d of the joint member 1, for the flange plate 3 The lifting does not produce meshing or friction that becomes a great resistance.
在有很大水平剪力變形產生於疊層橡膠體7的情況所產生的彎曲力矩導致疊層橡膠體7的端部浮起的現象，可以使朝向產生浮起的範圍的橡膠材料及黏接層的鉛直方向的過大拉伸力減低，結果可以確保疊層橡膠體7的健全性，並且疊層橡膠體7產生較大水平剪力變形時的硬化現象導致的水平力的顯著上升也能被抑制，所以可防止在較大水平剪力變形下的免震週期縮短，可在廣闊範圍獲得較長週期，而具有在大地震時能確保安全性的效果。The bending moment generated in the case where a large amount of shear deformation is generated in the laminated rubber body 7 causes the end portion of the laminated rubber body 7 to float, and the rubber material and the bonding range in the range in which the floating is generated can be made. The excessively large tensile force in the vertical direction of the layer is reduced, and as a result, the soundness of the laminated rubber body 7 can be ensured, and the significant increase in the horizontal force due to the hardening phenomenon when the laminated rubber body 7 is subjected to a large horizontal shear deformation can be It suppresses, so it can prevent the shortening of the earthquake-free period under a large level of shear deformation, and can obtain a long period in a wide range, and has the effect of ensuring safety in a large earthquake.
在上述實施方式，雖然是將接合構件1的外周面側圓筒狀鋼材1e的凸緣部1e'接合於凸緣板3的上面，而也可不設置凸緣部1e'，使外周面側圓筒狀鋼材1e的外周面與凸緣板3的貫穿孔3a的內周面嵌合，將外周面側圓筒狀鋼材1e固定於凸緣板3。而在上側凸緣板3B上升之後，為了防止，下降時接合構件1產生脫落，而外周面側圓筒狀鋼材1e的凸緣部1e'不復原到初期位置，以固定用螺栓將凸緣部1e'機械性地固定到凸緣板3也可以。In the above-described embodiment, the flange portion 1e' of the outer peripheral surface side cylindrical steel material 1e of the joint member 1 is joined to the upper surface of the flange plate 3, and the flange portion 1e' may not be provided, and the outer peripheral surface side may be rounded. The outer circumferential surface of the tubular steel material 1e is fitted to the inner circumferential surface of the through hole 3a of the flange plate 3, and the outer circumferential surface side cylindrical steel material 1e is fixed to the flange plate 3. After the upper flange plate 3B is raised, in order to prevent the joint member 1 from falling off during the lowering, the flange portion 1e' of the outer peripheral surface side cylindrical steel material 1e is not restored to the initial position, and the flange portion is fixed by the bolt. It is also possible to mechanically fix 1e' to the flange plate 3.
接著，針對本發明的疊層橡膠體用接合構件的第二實施方式，參考第5圖來加以說明。Next, a second embodiment of the joined member for a laminated rubber body of the present invention will be described with reference to FIG.
該接合構件21，其不同之處只有在，具有：於第1圖所示的接合構件1的內周面側圓筒狀鋼材1a從接合構件1的上面朝上方延伸設置的內周面側圓筒狀鋼材21a，其他構造與接合構件1相同。作為安裝螺栓22，取代第1圖的作為安裝螺栓2的具有六角孔的螺栓而使用六角螺栓。其他，凸緣板3、錨板4及空心螺母5，使用與第一實施方式相同的構件，雖然省略圖示，而將接合構件21取代接合構件1，將安裝螺栓22取代安裝螺栓2，而使用於第3圖所示的構造體13。 The joint member 21 is different from the inner peripheral surface side round extending from the upper surface of the joint member 1 on the inner peripheral surface side of the joint member 1 shown in Fig. 1 . The tubular steel material 21a has the same structure as the joint member 1. As the mounting bolt 22, a hexagon bolt is used instead of the bolt having a hexagonal hole as the mounting bolt 2 in Fig. 1 . In the other, the flange member 3, the anchor plate 4, and the hollow nut 5 are the same members as those of the first embodiment. Instead of the illustration, the joint member 21 is replaced with the joint member 1 and the mounting bolt 22 is used instead of the mounting bolt 2. The structure 13 shown in Fig. 3 is used.
之所以在接合構件21設置內周面側圓筒狀鋼材21a，是為了即使在如第4圖所示，在地震時等，在疊層橡膠體7的凸緣板3、固定於下部構造體9的錨板4之間，朝鉛直方向產生浮起的情形，要讓安裝螺栓22的頭部22a、與接合構件21的內周面側圓筒狀鋼材21a以外的部分不會接觸。藉此，藉由接合構件21，確保疊層橡膠體7的預定的浮起量，且能將疊層橡膠體7接合在第3圖所示的上部構造體8及下部構造體9。而針對接合構件21的安裝方法及動作，除上述要點之外，是與第1圖~第4圖所示的接合構件1相同，所以省略該說明。 The inner circumferential surface side cylindrical steel material 21a is provided in the joint member 21 in order to fix the flange plate 3 of the rubber body 7 to the lower structure body even during earthquakes, as shown in Fig. 4 . When the anchor plates 4 of 9 are floated in the vertical direction, the head portion 22a of the mounting bolt 22 does not come into contact with a portion other than the inner circumferential surface side cylindrical steel material 21a of the joint member 21. Thereby, the predetermined amount of floating of the laminated rubber body 7 is ensured by the joint member 21, and the laminated rubber body 7 can be joined to the upper structure 8 and the lower structure 9 shown in Fig. 3 . The attachment method and operation of the joint member 21 are the same as those of the joint member 1 shown in FIGS. 1 to 4 except for the above points, and thus the description thereof is omitted.
接著，針對本發明的疊層橡膠體用接合構件的第三實施方式，參考第6圖來說明。 Next, a third embodiment of the joined member for a laminated rubber body of the present invention will be described with reference to FIG.
在本實施方式，使用第1圖所示的接合構件1，使用作為安裝螺栓22的六角螺栓，在安裝螺栓22的頭部22a與接合構件1的內周面側圓筒狀鋼材1a之間中介安裝有套環24。其他凸緣板3、錨板4、及空心螺母5，是用與第一實施方式相同的構件，省略圖示，而也能將接合構件1、安裝螺栓22及套環24使用在第3圖所示的構造體13。 In the present embodiment, the joint member 1 shown in Fig. 1 is used, and the hexagonal bolt as the mounting bolt 22 is used to intervene between the head portion 22a of the mounting bolt 22 and the inner peripheral surface side cylindrical steel material 1a of the joint member 1. A collar 24 is installed. The other flange plate 3, the anchor plate 4, and the hollow nut 5 are the same members as those of the first embodiment, and the joint member 1, the mounting bolt 22, and the collar 24 can also be used in the third figure. The structure 13 shown.
之所以設置套環24，與上述第二實施方式同樣地，是為了即使在如第4圖所示，在地震時等，在疊層橡膠體7的凸緣板3、固定於下部構造體9的錨板4之間，朝鉛直 方向產生浮起的情形，要讓安裝螺栓22的頭部22a、與接合構件1的內周面側圓筒狀鋼材1a以外的部分不會接觸。藉此，藉由接合構件1，確保疊層橡膠體7的預定的浮起量，且能將疊層橡膠體7接合在第3圖所示的上部構造體8及下部構造體9。而針對接合構件1的安裝方法及動作，除上述要點之外，是與第1圖~第4圖所示的接合構件1相同，所以省略該說明。 In the same manner as in the second embodiment, the flanges 3 of the laminated rubber body 7 are fixed to the lower structure 9 in the event of an earthquake or the like as shown in Fig. 4, as in the fourth embodiment. Between the anchor plates 4, straight When the direction is raised, the head portion 22a of the mounting bolt 22 does not come into contact with a portion other than the cylindrical material 1a on the inner circumferential surface side of the joint member 1. Thereby, the predetermined amount of floating of the laminated rubber body 7 is ensured by the joining member 1, and the laminated rubber body 7 can be joined to the upper structure 8 and the lower structure 9 shown in Fig. 3 . The attachment method and operation of the joint member 1 are the same as those of the joint member 1 shown in FIGS. 1 to 4 except for the above points, and thus the description thereof is omitted.
接著，針對本發明的疊層橡膠體用接合構件的第四實施方式，參考第7圖來說明。 Next, a fourth embodiment of the joined member for a laminated rubber body of the present invention will be described with reference to FIG.
該接合構件31，只有在內周面側圓筒狀鋼材31a的內面螺設有母螺紋部31f之處，與第1圖所示的接合構件1不同，其他構造與接合構件1相同。作為安裝螺栓32，取代第1圖的作為安裝螺栓2的具有六角孔的螺栓而使用具有六角孔的固定螺栓。其他，凸緣板3、錨板4及空心螺母5，使用與第一實施方式相同的構件，雖然省略圖示，而將接合構件31取代接合構件1，將安裝螺栓32取代安裝螺栓2，而使用於第3圖所示的構造體13。 In the joint member 31, only the female screw portion 31f is screwed to the inner surface of the cylindrical material 31a on the inner circumferential surface side, and unlike the joint member 1 shown in Fig. 1, the other structure is the same as that of the joint member 1. As the mounting bolt 32, a fixing bolt having a hexagonal hole is used instead of the bolt having a hexagonal hole as the mounting bolt 2 in Fig. 1 . In the other case, the flange member 3, the anchor plate 4, and the hollow nut 5 are the same members as those of the first embodiment. Instead of the illustration, the joint member 31 is replaced with the joint member 31, and the mounting bolt 32 is used instead of the mounting bolt 2. The structure 13 shown in Fig. 3 is used.
在本實施方式，使在凸緣板3的貫穿孔3a處收容的接合構件31的母螺紋部31f與安裝螺栓32的公螺紋部32a螺合，並且使安裝螺栓32與空心螺母5螺合，將接合構件31的內周面側圓筒狀鋼材31a不移動地固定在錨板4。藉此，如第4圖所示，在地震時等，在疊層橡膠體7的凸緣板3與固定在下部構造體9的錨板4之間，即使朝鉛直方向產生浮起，接合構件1能在鉛直方向產生剪力變形，將疊層橡膠體7的朝上方的浮起情形吸收，防止在疊層橡膠體7的彈性層、黏接層等產生較大拉伸力，而能防止疊層橡膠體7損傷或斷裂。In the present embodiment, the female screw portion 31f of the joint member 31 accommodated in the through hole 3a of the flange plate 3 is screwed to the male screw portion 32a of the mounting bolt 32, and the mounting bolt 32 is screwed to the hollow nut 5, The inner circumferential surface side cylindrical steel material 31a of the joint member 31 is fixed to the anchor plate 4 without moving. As a result, as shown in FIG. 4, in the event of an earthquake or the like, the flange member 3 of the laminated rubber body 7 and the anchor plate 4 fixed to the lower structure body 9 are floated in the vertical direction, and the joint member is formed. 1 can generate shear deformation in the vertical direction, and absorb the upwardly floating state of the laminated rubber body 7 to prevent a large tensile force from being generated in the elastic layer, the adhesive layer, and the like of the laminated rubber body 7, and can be prevented. The laminated rubber body 7 is damaged or broken.
接著，針對本發明的疊層橡膠體用接合構件的第五實施方式，參考第8圖來說明。Next, a fifth embodiment of the joined member for a laminated rubber body of the present invention will be described with reference to FIG.
在本實施方式，使用第1圖所示的接合構件1，作為安裝螺栓42，是使用頭下長度較第1圖所示的安裝螺栓2更長的具有六角孔的螺栓，在安裝螺栓42的頭部42a與接合構件1的內周面側圓筒狀鋼材1a之間中介安裝有防止浮起用擋塊43。該防止浮起用擋塊43，由鋼材等所構成而在圓筒狀的主體43a的上端部具備有凸緣部43b。其他，凸緣板3、錨板4及空心螺母5，使用與第一實施方式相同的構件，雖然省略圖示，而能將接合構件1、安裝螺栓42及防止浮起用擋塊43使用於第3圖所示的構造體13。In the present embodiment, the joint member 1 shown in Fig. 1 is used as the mounting bolt 42 as a bolt having a hexagonal hole longer than the mounting bolt 2 shown in Fig. 1 and the bolt 42 is attached to the bolt 42. The floating prevention stopper 43 is interposed between the head portion 42a and the inner peripheral surface side cylindrical steel material 1a of the joint member 1. The floating prevention stopper 43 is made of a steel material or the like, and is provided with a flange portion 43b at an upper end portion of the cylindrical main body 43a. In the flange member 3, the anchor plate 4, and the hollow nut 5, the same members as those of the first embodiment are used, and the joint member 1, the mounting bolt 42, and the floating prevention stopper 43 can be used for the first embodiment. 3 is the structure 13 shown in the figure.
之所以設置防止浮起用擋塊43，如第4圖所示，即使在地震時等，疊層橡膠體7的凸緣板3與固定在下部構造體9的錨板4之間，朝鉛直方向產生浮起時，在第8圖，要讓安裝螺栓42的頭部42a、與接合構件1的內周面側圓筒狀鋼材1a以外的部分不會接觸，並且當藉由上述鉛直方向的浮起而讓接合構件1的外周面側圓筒狀鋼材1e朝上方移動時，外周面側圓筒狀鋼材1e會抵接於防止浮起用擋塊43的凸緣部43b的下面，防止其朝更上方移動。The reason why the floating prevention stopper 43 is provided is as shown in Fig. 4, even in the event of an earthquake or the like, the flange plate 3 of the laminated rubber body 7 and the anchor plate 4 fixed to the lower structure body 9 are oriented in the vertical direction. When the float is generated, in the eighth drawing, the head 42a of the mounting bolt 42 is not in contact with the portion other than the cylindrical material 1a on the inner peripheral surface side of the joint member 1, and is floated by the above vertical direction. When the outer peripheral surface side cylindrical steel material 1e of the joining member 1 is moved upward, the outer peripheral surface side cylindrical steel material 1e abuts against the lower surface of the flange portion 43b of the floating preventing stopper 43, and prevents it from facing further. Move above.
藉由上述構造，與第1圖所示的接合構件1同樣的，確保疊層橡膠體7的預定的浮起量，且能將疊層橡膠體7接合於第3圖所示的上部構造體8及下部構造體9，並且在接合構件1產生過大的剪力變形，換言之產生超過預定的設定量以上的大小的浮起量時，外周面側圓筒狀鋼材1e會抵接於防止浮起用擋塊43的凸緣部43b的下面，而能將接合構件1的圓筒狀橡膠1b、1d的剪力變形量控制在安全範圍，所以能防止疊層橡膠體7損壞。According to the above configuration, the predetermined amount of floating of the laminated rubber body 7 is ensured similarly to the joining member 1 shown in Fig. 1, and the laminated rubber body 7 can be joined to the upper structure shown in Fig. 3 . 8 and the lower structure body 9, when the joint member 1 is excessively deformed by shear force, in other words, when the amount of floating exceeds a predetermined amount or more, the outer peripheral surface side cylindrical steel material 1e abuts against the floating prevention. The lower surface of the flange portion 43b of the stopper 43 can control the amount of shear deformation of the cylindrical rubbers 1b and 1d of the joint member 1 within a safe range, so that the laminated rubber body 7 can be prevented from being damaged.
在使用該接合構件1的情況，在凸緣板3的浮起沒有垂直於安裝螺栓42的軸線，與軸線具有角度的情況，在接合構件1的圓筒狀橡膠1b、1d產生彎曲變形，而具有對於凸緣板3的浮起不會產生成為很大阻力的嚙合或摩擦的效果。In the case where the joint member 1 is used, in the case where the floating of the flange plate 3 is not perpendicular to the axis of the mounting bolt 42 and has an angle with the axis, the cylindrical rubbers 1b, 1d of the joint member 1 are bent and deformed. There is an effect that the floating of the flange plate 3 does not cause meshing or friction which becomes a large resistance.
接著，針對本發明的疊層橡膠體用接合構件的第六實施方式，參考第9圖來說明。Next, a sixth embodiment of the joined member for a laminated rubber body of the present invention will be described with reference to FIG.
在本實施方式，在第5圖所示的接合構造，更將作為防止浮起用擋塊的墊片23，中介安裝在安裝螺栓22的頭部22a與接合構件21的內周面側圓筒狀鋼材21a之間。藉由使用該墊片23，如第4圖所示，當地震時等，在疊層橡膠體7的凸緣板3與固定在下部構造體9的錨板4之間，即使朝鉛直方向產生浮起，在第9圖，要讓安裝螺栓22的頭部22a、與接合構件21的內周面側圓筒狀鋼材21a以外的部分不會接觸，並且當藉由上述鉛直方向的浮起而讓接合構件21的外周面側圓筒狀鋼材21e朝上方移動時，外周面側圓筒狀鋼材21e會抵接於墊片23的下面，防止其朝更上方移動。In the joint structure shown in FIG. 5, the gasket 23 as the stopper for preventing the floating is further attached to the head portion 22a of the mounting bolt 22 and the inner peripheral surface side of the joint member 21 in a cylindrical shape. Between steel 21a. By using the spacer 23, as shown in Fig. 4, even when the earthquake occurs, the flange plate 3 of the laminated rubber body 7 and the anchor plate 4 fixed to the lower structure 9 are generated in the vertical direction. In the ninth figure, the head portion 22a of the mounting bolt 22 is not in contact with a portion other than the inner peripheral surface side cylindrical steel material 21a of the joint member 21, and is floated by the above-mentioned vertical direction. When the outer peripheral surface side cylindrical steel material 21e of the joining member 21 is moved upward, the outer peripheral surface side cylindrical steel material 21e abuts on the lower surface of the shim 23, and prevents it from moving upward.
藉由上述構造，與第8圖所示的接合構造同樣的，確保疊層橡膠體7的預定的浮起量，且能將疊層橡膠體7接合於第3圖所示的上部構造體8及下部構造體9，並且在接合構件21產生過大的剪力變形，換言之產生超過預定的設定量以上的大小的浮起量時，外周面側圓筒狀鋼材21e會抵接於墊片23的下面，而能將接合構件21的圓筒狀橡膠21b、21d的剪力變形量控制在安全範圍，所以能防止疊層橡膠體7損壞。With the above-described structure, the predetermined amount of floating of the laminated rubber body 7 is ensured in the same manner as the joint structure shown in Fig. 8, and the laminated rubber body 7 can be joined to the upper structure 8 shown in Fig. 3 . In the lower structure 9 and the excessive shear deformation of the joint member 21, in other words, a floating amount exceeding a predetermined amount or more, the outer peripheral surface side cylindrical steel material 21e abuts against the gasket 23. Next, the amount of shear deformation of the cylindrical rubbers 21b and 21d of the joint member 21 can be controlled to a safe range, so that the laminated rubber body 7 can be prevented from being damaged.
接著，針對本發明的的疊層橡膠體用接合構件的第七實施方式，參考第10圖來說明。Next, a seventh embodiment of the joined member for a laminated rubber body of the present invention will be described with reference to FIG.
在本實施方式，在第6圖所示的接合構造，更將作為防止浮起用擋塊的墊片23，中介安裝在安裝螺栓22的頭部22a與套環24的上面之間。藉由該構造，與上述第8圖及第9圖所示的接合構造同樣的，確保第4圖所示的疊層橡膠體7的預定的浮起量，且能將疊層橡膠體7接合於第3圖所示的上部構造體8及下部構造體9，並且在接合構件1產生超過預定的設定量以上的大小的浮起量時，外周面側圓筒狀鋼材1e會抵接於墊片23的下面，而能將接合構件1的圓筒狀橡膠1b、1d的剪力變形量控制在安全範圍，所以能防止橡膠材料損壞。In the present embodiment, the joint 23 shown in Fig. 6 is further interposed between the head portion 22a of the mounting bolt 22 and the upper surface of the collar 24 as a spacer 23 for preventing the floating stopper. With this configuration, similarly to the joint structure shown in Figs. 8 and 9, the predetermined amount of floating of the laminated rubber body 7 shown in Fig. 4 can be secured, and the laminated rubber body 7 can be joined. In the case of the upper structure 8 and the lower structure 9 shown in Fig. 3, when the joint member 1 has a floating amount exceeding a predetermined amount or more, the outer peripheral surface side cylindrical steel material 1e abuts against the mat. On the lower surface of the sheet 23, the amount of shear deformation of the cylindrical rubbers 1b and 1d of the joint member 1 can be controlled within a safe range, so that the rubber material can be prevented from being damaged.
接著，針對本發明的的疊層橡膠體用接合構件的第八實施方式，參考第11圖來說明。Next, an eighth embodiment of the joined member for a laminated rubber body of the present invention will be described with reference to FIG.

The portion 35a is screwed to the female screw portion 36a of the floating prevention stopper 36. With this configuration, as in the joint structure shown in FIGS. 8 to 10, the predetermined amount of floating of the laminated rubber body 7 shown in FIG. 4 is secured, and the laminated rubber body 7 can be joined. In the case of the upper structure 8 and the lower structure 9 shown in FIG. 3, when the joint member 31 has a floating amount exceeding a predetermined amount or more, the outer peripheral surface side cylindrical steel material 31e abuts against the prevention. The lower surface of the floating stopper 36 can control the amount of shear deformation of the cylindrical rubbers 31b and 31d of the joint member 31 within a safe range, so that the rubber material can be prevented from being damaged.
在上述實施方式，將接合構件1等作成剪力型筒狀橡膠體，具備有：三個圓筒狀鋼材1a、1c、1e、與中介安裝在各圓筒狀鋼材的圓筒狀橡膠1b、1d，而也可以不設置中間圓筒狀鋼材1c，以兩個圓筒狀鋼材1a、1e構成，而也可相反地，設置複數的中間圓筒狀鋼材1c。在設置有防止浮起用擋塊的方式，能在該擋塊與接合構件之配置緩衝用薄片，而能減低接觸時的衝擊。In the above-described embodiment, the joint member 1 or the like is formed as a shear-type tubular rubber body, and includes three cylindrical steel materials 1a, 1c, and 1e, and a cylindrical rubber 1b that is interposed between each cylindrical steel material. In the case of 1d, the intermediate cylindrical steel material 1c may be omitted, and the two cylindrical steel materials 1a and 1e may be used. Alternatively, a plurality of intermediate cylindrical steel materials 1c may be provided.
