Abstract

A composite metal core 30 incorporated in a laminated rubber bearing for damper having two different kinds of metal material. An outer metal 31 includes a material having a high rigidity and an excellent plastic deformability. An inner metal 32 includes a material having low rigidity and an excellent plastic deformability. By making a rising rate of a bending rigidity of the composite metal core higher than a rising rate of a shear rigidity of the composite core, the composite metal core enters a deformation mode in which a superior shear deformability is created. In that deformation mode, the performance of absorbing energy generated in a process of plastic deformation is stabilized. And at the same time, an average horizontal shear yield stress degree of the composite metal core can be set at an arbitral level between the horizontal shear yield stress degrees of the two kinds of metal.

Description

隔震裝置及其製造方法 Isolation device and method of manufacturing same

本發明係關於一種可以從地震中安全地保護構造物的隔震裝置當中、尤其是具備有內置能量吸收用阻尼器(damper)之積層橡膠體的隔震裝置。 The present invention relates to a vibration isolation device that can safely protect a structure from an earthquake, and particularly to a vibration isolation device including a laminated rubber body having a built-in damper for energy absorption.

由於隔震裝置，係可以對大地震時較強之地震運動降低構造物的搖動，所以可以與建築物之構造體骨架一起提高包含家具或設備備品等內部容納物的建築物整體之耐震安全性。 Because the seismic isolation device can reduce the shaking of the structure during the earthquake movement that is strong during a major earthquake, it is possible to improve the overall seismic safety of the building containing the internal contents such as furniture or equipment together with the structural skeleton of the building. .

在用以實現隔震構造物的隔震裝置中，係需要具有以下兩個功能：一邊支撐構造物之重量一邊可以進行較大之水平變形的隔震器(isolator)功能；以及吸收因地震而被投入於構造物之振動能量的阻尼器功能。作為至今已實用化的隔震系統，有1)天然橡膠系積層橡膠+分開設置式阻尼器、2)高衰減積層橡膠、3)含鉛芯積層橡膠等的積層橡膠系隔震系統，其他也已實用化的有4)滑動支承系隔震裝置、5)滾動系支承系隔震裝置等。 In the vibration isolating device for realizing the seismic isolation structure, it is required to have the following two functions: an isolator function capable of performing a large horizontal deformation while supporting the weight of the structure; and absorption due to an earthquake. A damper function that is applied to the vibration energy of the structure. As a vibration isolation system that has been put into practical use, there are 1) natural rubber-based laminated rubber + split-type damper, 2) high-attenuation laminated rubber, and 3) laminated rubber-based vibration isolation system including lead-core laminated rubber. There are 4) sliding support system isolation devices, 5) rolling system support system isolation devices, and the like.

在此等的隔震裝置中，受到世界較高評價、且具有較多實績的有在紐西蘭已被發明、開發出的「含鉛芯積層橡膠隔震裝置」(參照專利文獻1及專利文獻2)。此裝置，係在作為隔震器之積層橡膠支承的平面中央部一處或平面內複數處，封入發揮作為阻尼器(能量吸收機構)之功能的鉛芯，且就連日本及海外(紐西蘭、美國、義大利、台灣、土耳其、中國、南美等)也包含在內而在世界上獲較高評價之代表性的隔震裝置。 In the seismic isolation devices, the "lead-core laminated rubber isolation device" that has been invented and developed in New Zealand has been evaluated by the world. (Refer to Patent Document 1 and Patent. Literature 2). This device is installed in a plurality of planes at the center of the plane of the laminated rubber supported by the isolator, and is sealed with a function as a damper (energy absorbing mechanism), and even Japan and overseas (New Zealand) Lan, the United States, Italy, Taiwan, Turkey, China, South America, etc.) are also included in the world and are highly representative of the isolation device in the world.

該隔震裝置，係具有以下的特徵：以一個裝置兼備隔震構造所需的隔震器功能和阻尼器功能之兩者；以及藉由發揮阻尼器功能的鉛芯和發揮隔震器功能的積層橡膠之組合而可以相當自由地調整作為隔震構造之性能、即隔震裝置之復原力特性。 The vibration isolation device has the following features: a vibration isolation function and a damper function required for the isolation structure of one device; and a lead core that functions as a damper and functions as a vibration isolator. The combination of the laminated rubbers can relatively easily adjust the performance as the seismic isolation structure, that is, the restoring force characteristics of the vibration isolating device.

另一方面，由於近年來社會對環境問題之認識已開始高漲，所以承蒙社會討厭作為材料之含鉛毒性的潮流高漲，而進行了將與鉛同樣具有塑性變形性能優越的超塑性金屬作為內置芯材料來利用的提案。作為具體的材料，也有開發或提案一種使用具有作為與鉛相同之結晶構造之面心立方晶格的錫及錫-鉍合金等的「含錫栓塞積層橡膠」(專利文獻3)、利用鋅-鋁系合金者(專利文獻4)等。 On the other hand, in recent years, society's understanding of environmental issues has begun to rise, so the society has hated the trend of lead poisoning as a material, and superplastic metal with the same plastic deformation property as lead has been built as a core. The proposal to use the material. As a specific material, a "tin-containing plug-laminated rubber" using a tin and tin-bismuth alloy having a face-centered cubic lattice which is the same crystal structure as lead (Patent Document 3), and zinc- Aluminum alloys (Patent Document 4) and the like.

其他作為能量吸收用之芯材料，也有提案一種利用衰減性能較高之高衰減橡膠等的高分子材料者、將不同硬度之兩種塑膠樹脂材料予以混合成形者(專利文獻 5、6)、使用將橡膠等高分子材料和鐵粉或玻璃珠(glass beads)等之粒狀物予以混合成型的人造阻尼器材料(專利文獻7)等。 As a core material for energy absorption, there is also proposed a polymer material using a high-attenuation rubber having a high attenuation property, and a mixture of two plastic resin materials having different hardnesses (Patent Document) 5, 6) A synthetic damper material (patent document 7) obtained by mixing a polymer material such as rubber and a granular material such as iron powder or glass beads (Patent Document 7).

第1圖係顯示本發明作為對象的習知阻尼器(金屬芯)內置型之隔震裝置的基本構成，其中(1)為縱向剖視圖；(2)為水平剖視圖。在積層橡膠體1之中心部內置金屬芯3，在其上下端部附近具有厚度較厚之端部鋼板25，在其外側具有凸緣鋼板4。在本例中，係在圓形平面的積層橡膠體1之平面中央具有內置金屬芯3，而該金屬芯3之平面形狀為圓形。 Fig. 1 is a view showing a basic configuration of a conventional damper (metal core) built-in type of vibration isolation device to which the present invention is applied, wherein (1) is a longitudinal sectional view; (2) is a horizontal sectional view. The metal core 3 is built in the center portion of the laminated rubber body 1, and has an end steel plate 25 having a thick thickness in the vicinity of the upper and lower end portions thereof, and a flange steel plate 4 on the outer side. In this example, a metal core 3 is built in the center of the plane of the laminated rubber body 1 in a circular plane, and the metal core 3 has a circular shape in plan view.

如第1圖所示，通常被稱為「LRB」之含鉛栓塞積層 橡膠或被稱為「SnRB」之含錫栓塞積層橡膠等的金屬芯內置型隔震裝置、或是內置藉由橡膠和鐵粉之混合所得之人造材料芯等的隔震裝置，係形成為以下的構造：在將薄的平板形狀之彈性材料11(通常為橡膠層)和剛性材料2(通常為鋼板)交替地積層於上下方向的積層橡膠體1之內部，內置有伴隨至少一個以上之塑性變形而發揮能量吸收功能的芯材料3。雖然能量吸收用的芯材料3(內置芯)，也有分散配置有複數個，但是在其為積層橡膠體之平面非常大的大型裝置之情況下，基本上通常是在積層橡膠體1之平面中央部配置有一個。 As shown in Figure 1, the lead plug embedding layer, commonly referred to as "LRB" A metal core built-in type vibration isolating device such as rubber or a tin-containing plug laminated rubber called "SnRB" or a vibration-insulating device including a synthetic material core obtained by mixing rubber and iron powder is formed as follows. The structure is such that a thin flat plate-shaped elastic material 11 (usually a rubber layer) and a rigid material 2 (usually a steel plate) are alternately laminated in the up-and-down direction of the laminated rubber body 1, and at least one plasticity is built in. The core material 3 which is deformed to exhibit an energy absorbing function. Although the core material 3 (internal core) for energy absorption is also dispersed in a plurality of places, in the case of a large device having a very large plane of the laminated rubber body, it is basically in the center of the plane of the laminated rubber body 1. There is one configuration.

雖然為了提高隔震裝置之衰減性能，而只要加大發揮能量吸收性能的內置芯即可，但是當內置芯之直徑(平面尺寸)比積層橡膠直徑過於大一定比率以上時，由於積層橡膠體之水平變形模式就會崩壞，或是會在已進行水平變形之情況的積層橡膠體之安全性或鉛直荷重支撐能力上發生問題，所以一般而言需要將芯直徑抑制在積層橡膠直徑之20%左右乃至20%以下。 In order to improve the attenuation performance of the isolation device, it is only necessary to increase the energy-absorbing performance of the built-in core. However, when the diameter (planar size) of the built-in core is too large or more than the laminated rubber diameter, the laminated rubber body The horizontal deformation mode will collapse, or there will be problems in the safety of the laminated rubber body or the vertical load supporting ability in the case of horizontal deformation, so it is generally necessary to suppress the core diameter to 20% of the laminated rubber diameter. Left and right or even 20% or less.

於是，從藉由芯材料之選擇來調整衰減性能的觀點來看，雖然作為內置於積層橡膠的阻尼器材料至今也有提案如上述的各種材料，但是利用上述專利文獻5至7所例示的樹脂材料或粒狀物者，因其阻力較小(每一單位截面積之剪切阻力(應力強度水準)較低)，故而當以大重量之大型構造物用的隔震裝置作為前提時，就必須將芯直徑形成得非常大，而作為現實的尺寸就無法成立。作 為能夠使用的對象物，不得不限定於獨建住宅等之較輕量且小規模的構造物。 Then, from the viewpoint of adjusting the damping performance by the selection of the core material, although various materials such as those described above have been proposed as the damper material built in the laminated rubber, the resin materials exemplified in the above Patent Documents 5 to 7 are used. Or the granular material, because the resistance is small (the shear resistance (stress intensity level) per unit cross-sectional area is low), so when it is premised on the isolation device for large structures with large weight, it is necessary The core diameter is formed to be very large, and the actual size cannot be established. Make The object to be used has to be limited to a relatively lightweight and small-scale structure such as a house.

因而，當以大重量之大型構造物用的隔震裝置作為對象時，作為內置芯用的阻尼器材料，從阻力之應力強度水準的觀點來看還是金屬材料較為適合。 Therefore, when a vibration isolating device for a large-sized structure having a large weight is used, the damper material for the built-in core is preferably a metal material from the viewpoint of the stress intensity level of the resistance.

金屬材料當中，雖然在專利文獻3中已有提案錫-鉍、錫-銦等的低熔點合金材料，但是其熔點係如同表1所示要極低溫至117℃至138℃才會熔解。 Among the metal materials, although a low-melting alloy material such as tin-bismuth, tin-indium or the like has been proposed in Patent Document 3, the melting point thereof is as shown in Table 1 to be extremely low temperature to 117 ° C to 138 ° C to be melted.

由於發揮隔震裝置之阻尼器功能的內置芯，係以藉由伴隨隔震層之層間位移而致使的自身之塑性變形來吸收對構造物之地震輸入能量為目的，所以在地震時會因該吸收能量而發熱。該上升溫度，依至今的多數實驗已知對嚴峻的地震運動而言容易超過100℃。 Since the built-in core that functions as the damper function of the vibration isolating device absorbs the seismic input energy to the structure by the plastic deformation caused by the interlayer displacement of the isolation layer, it is necessary for the earthquake. Absorbs energy and heats up. This rising temperature, according to most experiments to date, is known to easily exceed 100 °C for severe seismic motion.

因而，此等的低熔點合金材料，在嚴酷的地震運動起作用的情況下到達熔點並熔解的可能性很高，且在該熔解前之高溫時阻力會降低，而使能量吸收性能顯著降低。因此，雖然此等的低熔點合金材料，為塑性金屬材料，但是不得不說將其作為以伴隨大地震時之塑性變形而 致使的能量吸收為目的的隔震裝置之內置芯用材料是不適當的。 Therefore, these low melting point alloy materials have a high possibility of reaching a melting point and melting under the action of severe earthquake motion, and the resistance is lowered at the high temperature before the melting, and the energy absorption performance is remarkably lowered. Therefore, although these low-melting alloy materials are plastic metal materials, they have to be said to be plastic deformation accompanying large earthquakes. The material for the core of the isolation device for the purpose of energy absorption is not suitable.

作為考量至今受注目、受檢討之塑性變形性能優異的金屬材料，係考慮鉛、錫、鋁、鋅、銅以及其等的合金材料之利用。 The use of lead, tin, aluminum, zinc, copper, and alloy materials thereof is considered as a metal material that has been inspected so far and has excellent plastic deformation properties.

將作為此等代表性的超塑性金屬之縱向彈性係數E、剪切彈性係數G、體積彈性係數K、蒲松比(Poisson’s ratio)v、熔點、室溫及熔點下之密度等物質的基本特性(機械性質)顯示於表2。 The basic properties of the materials such as the longitudinal elastic modulus E, the shear elastic modulus G, the bulk modulus K, the Poisson's ratio v, the melting point, the density at room temperature and the melting point of such representative superplastic metals ( Mechanical properties) are shown in Table 2.

如同週知般，此等材料當中至今採用實績最多的隔震裝置用內置芯之金屬材料，乃為純度99.99%以上的純鉛。雖然鉛，係具有所謂作為超塑性金屬具有非常大之塑性變形能力之優異的機械性質，但是因對人體具有毒性，故而根據環境衛生問題嚴峻的近來情勢來看有躲避該使用的傾向。又，就連其阻力在作為阻尼器用而言仍是稍微低些之點，尚有改良之餘地。 As is well known, the metal materials of the built-in core for the isolation device with the highest performance in these materials have been pure lead with a purity of 99.99% or more. Although lead has an excellent mechanical property as a superplastic metal having a very large plastic deformation ability, it is toxic to the human body, and therefore has a tendency to avoid this use in view of the recent serious environmental health problems. Moreover, even its resistance is still slightly lower as a damper, and there is still room for improvement.

另一方面，從避開鉛之毒性的觀點來看，以不具毒性之超塑性金屬受人注目的是錫。雖然採用錫作為內置金屬芯材料的含錫栓塞積層橡膠已被實用化，且該採用實績也著實進展中，但是當錫栓塞與鉛做比較時，因其阻力就會高至約二倍左右，故而採用於各個積層橡膠時會有阻力稍微過強的傾向。又，該強度係與作為金屬的硬度連動，且顯示因該硬度之故而缺乏如鉛能使塑性區域中的阻力以固定變形的均一性，且會與變形一起增大阻力的蝶型之履歷形狀。亦即，作為塑性變形特性而言，係以鉛較為優異。 On the other hand, from the viewpoint of avoiding the toxicity of lead, tin which is attracting attention as a non-toxic superplastic metal. Although tin-containing plug-laminated rubber using tin as a built-in metal core material has been put into practical use, and the actual performance is progressing, when the tin plug is compared with lead, the resistance is as high as about two times. Therefore, when used in each laminated rubber, there is a tendency that the resistance is slightly too strong. Further, the strength is in conjunction with the hardness as a metal, and the lack of uniformity such as lead which causes the resistance in the plastic region to be fixedly deformed due to the hardness, and the butterfly shape which increases the resistance together with the deformation . That is, as the plastic deformation property, lead is excellent.

又，錫栓塞，係在熱特性之觀點中具有以下所示的致命缺點。 Further, the tin plug has the fatal disadvantage shown below from the viewpoint of thermal characteristics.

表3係主要顯示鉛和錫的熱特性與機械性質之比較。亦即，錫的阻力(剪切降伏應力強度)是強於鉛二倍左右，另一方面，具有熔點比鉛更低近100℃的顯著特性。 Table 3 shows mainly the comparison of the thermal and mechanical properties of lead and tin. That is, the resistance (shear stress) of tin is twice as strong as that of lead, and on the other hand, it has a remarkable characteristic that the melting point is lower by 100 ° C than lead.

如今，作為最一般的(標準的)建築物用積層橡膠，係假定直徑1000mm 之積層橡膠(芯尺寸：直徑200mm ×高度H400mm)，且假定有±300mm之強制變形作為大地震時之水平變形而作用於此的情況，當算定從地震前之假定溫度20℃至該金屬栓塞到達熔點之激盪週期數時，就如同表3(下半部)所示，就會在鉛栓塞時約為18週期，相對於此，在錫栓塞時以其1/3左右之7.6週期到達熔點。 Today, as the most common (standard) building rubber, it is assumed to have a diameter of 1000mm. Laminated rubber (core size: diameter 200mm × height H400mm), and assuming that forced deformation of ±300mm acts as a horizontal deformation during a large earthquake, when calculating the number of exciting cycles from the assumed temperature of 20 ° C before the earthquake to the melting point of the metal plug As shown in Table 3 (lower half), it is about 18 cycles at the time of lead plugging, whereas the melting point is reached at 7.6 cycles of about 1/3 of the tin plug.

此差異係起因於以下的特性作為錫栓塞的特徵：因錫栓塞之阻力高近鉛的約二倍，故而每1週期的吸收能量、即發熱量高近二倍，反之，熔點也比鉛更低100℃。雖然可預想因阻力會依伴隨能量吸收所引起之溫度上升而降低，故而到達熔點的實際之激盪週期數會變得更多，但是可明白無論是哪一種能量吸收性能都會因阻力之降低而顯著地早期降低。 This difference is due to the following characteristics as a characteristic of tin plug: since the resistance of tin plug is about twice as high as that of lead, the energy absorbed per cycle, that is, the calorific value is nearly twice as high, and conversely, the melting point is more than lead. Low 100 ° C. Although it is expected that the resistance will decrease according to the temperature rise caused by the energy absorption, the actual number of exciting cycles reaching the melting point will become more, but it can be understood that any energy absorption performance will be significantly reduced by the resistance. Early reduction in the ground.

尤其是，在比2011年東北地方太平洋海岸地震更接近發生之可能性較高的地震規模M9級之超巨大地震，已沿著南海海槽發生的情況下，由於以超過該假定之較大振幅長時間承受多次之反覆激盪的可能性較高，所以對較強之長週期、長時間持續地震運動而言，不得不說含栓塞積層橡膠具有嚴重的問題。 In particular, the M9-class super-large earthquake, which is more likely to occur than the 2011 Northeast Pacific Coast earthquake, has occurred along the South China Sea Trough, due to the large amplitude exceeding this assumption. It is highly probable that it will withstand repeated surges for a long time, so for a long period of long-term, long-term continuous earthquake movement, it has to be said that the rubber containing the plug layer has serious problems.

當歸納有關以上之隔震裝置(積層橡膠)用內置芯的爭論、問題點時就成為如下。首先，利用高分子 材料作為芯材料，因阻力水準較低故而作為阻尼器功能的性能較低，當將芯尺寸形成非常大時，就與裝置本身的不穩定化息息相關，且作為芯材料的性能方面不佳。又，金屬芯當中的低熔點合金材料(表1)，由於熔點過低，容易藉由吸收能量而到達熔點，所以此仍不適合作為芯材料。 When the arguments and problems concerning the built-in core for the above-mentioned isolation device (layered rubber) are summarized, the following is the case. First, use polymer As a core material, the material has a low performance as a damper function because of a low level of resistance. When the core size is formed to be very large, it is closely related to the instability of the device itself, and the performance as a core material is not good. Further, the low melting point alloy material (Table 1) among the metal cores is not suitable as a core material because the melting point is too low and it is easy to absorb the energy to reach the melting point.

雖然現實上作為內置芯材料的金屬材料，還是以至今實績較多的鉛和錫較有希望，但是如同表2所示，最柔軟的鉛和第二柔軟的錫，其等的彈性係數有三倍以上、剪切降伏強度約有近二倍之差異，其他材料則有更大的差異。亦即，雖然作為金屬芯的鉛，在變形性能方面優異，但是在強度上則稍微柔軟，反之，錫則過硬，就連變形特性也與鉛做比較時就存在有缺點。其他的鋁、鋅、銅等的金屬，因剛性高於錫以上，故而具有過強於錫栓塞以上的傾向。又，對鉛而言，也存在具有毒性的問題點。 Although metal materials which are actually built-in core materials are more promising than lead and tin which have been produced so far, as shown in Table 2, the softest lead and the second soft tin have three times the modulus of elasticity. The above, shear reduction strength is approximately twice as large, and other materials have larger differences. That is, although lead as a metal core is excellent in deformation performance, it is slightly soft in strength, whereas tin is too hard, and even when deformation characteristics are compared with lead, there are disadvantages. Other metals such as aluminum, zinc, and copper tend to be stronger than tin plugs because the rigidity is higher than that of tin. Moreover, for lead, there are also problems with toxicity.

如同以上所述，作為隔震裝置之內置芯材料，從強度位準的觀點來看，雖然不得不利用金屬芯，但是在最適當的強度、變形特性或機械性質、環境衛生上、處理上之安全性(毒性的存在程度)等的諸觀點中，就成為所謂「已完備所有要求條件的理想金屬芯材料是不存在的」。 As described above, as the built-in core material of the vibration isolation device, from the viewpoint of the strength level, although the metal core has to be utilized, it is the most suitable strength, deformation property or mechanical property, environmental sanitation, and treatment. Among the viewpoints of safety (degree of toxicity), etc., it is called "the ideal metal core material that has completed all the required conditions does not exist."

<構成7> <Structure 7>

一種隔震裝置的製造方法，係內置構成1至5中任一項所述的複合金屬芯之隔震裝置的製造方法，其特徵為：事先將前述內側金屬整形成既定之尺寸、形狀，且浸漬於已將前述外側金屬熔融的槽內，並在前述內側金屬之外表面形成前述外側金屬之表面鍍敷層，藉此製造前述複合金屬芯，或是，在已事先整形成既定之尺寸、形狀的前述內側金屬之至少側面表面上藉由熔射而噴吹前述外側金屬以形成前述外側金屬之薄膜，藉此製造前述複合金屬芯。 A method of manufacturing a vibration isolating device according to any one of the first to fifth aspect, wherein the inner metal is formed into a predetermined size and shape in advance, and Immersing in a groove in which the outer metal has been melted, and forming a surface plating layer of the outer metal on the outer surface of the inner metal, thereby manufacturing the composite metal core, or forming a predetermined size in advance, A surface of at least one side surface of the inner metal of the shape is blown by spraying the outer metal to form a film of the outer metal, whereby the composite metal core is manufactured.

本發明之功效的第1點，係在於可以任意設定金屬芯之水平剪切阻力。 The first point of the effect of the present invention is that the horizontal shear resistance of the metal core can be arbitrarily set.

因本發明，係將內置於積層橡膠的金屬芯構成作為將兩種金屬材料予以複合化所得的混合芯(hybrid core)，故而可以將金屬芯之水平剪切阻力，在以兩種金屬芯單獨 所構成的情況之兩個水平剪切阻力之中間的範圍內，自由地設定於任意的水平剪切阻力。 According to the present invention, the metal core built in the laminated rubber is formed as a hybrid core obtained by combining two kinds of metal materials, so that the horizontal shear resistance of the metal core can be separated by two metal cores. In the range between the two horizontal shear resistances in the case of the configuration, it is freely set to an arbitrary horizontal shear resistance.

亦即，在以同一截面積來比較塑性金屬芯之水平剪切阻力的情況下，相對於以外側金屬來單獨構成全剖面所得的金屬芯A之水平剪切阻力QA、和以內側金屬來單獨構成全剖面所得的金屬芯B之水平剪切阻力QB(QB<QA)，能夠將複合金屬芯C之水平剪切阻力QC，設為金屬芯A之水平剪切阻力QA與金屬芯B之水平剪切阻力QB之間的任意強度之水平剪切阻力，且設定為QB≦QC<QA。 That is, in the case of comparing the horizontal shear resistance of the plastic metal core with the same cross-sectional area, the horizontal shear resistance QA of the metal core A obtained by separately forming the full cross section with the outer metal, and the inner metal alone The horizontal shear resistance QB (QB<QA) of the metal core B obtained in the full profile can be used to set the horizontal shear resistance QC of the composite metal core C to the horizontal shear resistance QA of the metal core A and the level of the metal core B. The horizontal shear resistance of any intensity between the shear resistance QB is set to QB ≦ QC < QA.

另外，在上述中已包含QC=QB的是，在構成7中將外側金屬A藉由鍍敷或熔射來構成作為薄膜的情況下，其阻力QC係意指大概接近QB的(QC≒QB)情況。 In addition, in the case where QC=QB is included in the above, in the case where the outer metal A is formed into a thin film by plating or spraying in the configuration 7, the resistance QC means that it is approximately close to QB (QC≒QB). )Happening.

本發明之功效的第2點，雖然是與第1點同樣的功效，但是可以自如地調整金屬芯之強度(每一單位面積之水平剪切阻力)。 The second point of the effect of the present invention is the same as that of the first point, but the strength of the metal core (horizontal shear resistance per unit area) can be freely adjusted.

當以每一單位面積之平均剪切應力強度來表現金屬芯之水平剪切阻力時，就將外側金屬之降伏剪切應力強度設為T1、將內側金屬之降伏剪切應力強度設為T2(T2<T1)，而當將外側金屬之截面積A1對金屬芯之總截面積A0的比例設為RA1(=A1/A0)時，複合金屬芯之每一單位面積的平均降伏剪切應力強度T3，就成為T3=T1×RA1+T2(1-RA1)，且能夠藉由所複合的兩種金屬之面積比，設定在T1與T2之間的任意強度之平均剪切降伏應力 強度T3(T2≦T3<T1)。 When the horizontal shear resistance of the metal core is expressed by the average shear stress intensity per unit area, the shear stress intensity of the outer metal is set to T1, and the shear stress intensity of the inner metal is set to T2 ( T2<T1), and when the ratio of the cross-sectional area A1 of the outer metal to the total cross-sectional area A0 of the metal core is set to RA1 (=A1/A0), the average shear stress intensity per unit area of the composite metal core T3, which is T3=T1×RA1+T2(1-RA1), and can set the average shear stress of any strength between T1 and T2 by the area ratio of the two metals compounded. Strength T3 (T2 ≦ T3 < T1).

其次，作為本發明之功效的第3點，係在將對外側金屬採用彈性係數比內側金屬更高之材料的複合金屬芯之彎曲剛性EI3及剪切剛性GA3，與內側金屬芯單獨之彎曲剛性EI2及剪切剛性GA2做比較的情況下，由於決定金屬芯之彎曲剛性的剖面二次力矩I之貢獻率係越靠近芯剖面之外側就越高(對剖面內之各部微小面積的剖面二次力矩之貢獻，係與從芯中心至其存在位置之距離的二次方成正比)，所以當比較前者(複合金屬芯之剖面性能)對後者(內側金屬芯單獨之剖面性能)的上升率CEI=EI3/EI2、CGA=GA3/GA2時，一般而言就成為CEI>CGA。因而，在本發明之複合金屬芯中，由於彎曲剛性之上升率會變得比剪切剛性之上升率更高，所以作為使水平力作用於複合金屬芯的情況之變形模式，不易發生彎曲變形。亦即，因本發明之複合金屬芯，係不易發生彎曲變形，故而會成為剪切變形卓越型的變形模式，且產生更穩定的剪切變形，顯示穩定的能量吸收特性。 Next, as the third point of the effect of the present invention, the bending rigidity EI3 and the shear rigidity GA3 of the composite metal core having a material having a higher elastic modulus than the inner metal for the outer metal, and the bending rigidity of the inner metal core alone. When EI2 and shear-rigidity GA2 are compared, the contribution rate of the secondary moment I of the section which determines the bending rigidity of the metal core is higher as it is closer to the outer side of the core section (two times of the minor area of each section in the section) The contribution of the moment is proportional to the square of the distance from the center of the core to its position of existence), so when comparing the rise rate of the former (the cross-sectional performance of the composite metal core) to the latter (the profile performance of the inner metal core alone) CEI When =EI3/EI2, CGA=GA3/GA2, it is generally CEI>CGA. Therefore, in the composite metal core of the present invention, since the rate of increase in bending rigidity becomes higher than the rate of increase in shear rigidity, bending deformation is less likely to occur as a deformation mode in which a horizontal force acts on the composite metal core. . That is, since the composite metal core of the present invention is less likely to be bent and deformed, it is a deformation mode excellent in shear deformation, and produces more stable shear deformation and exhibits stable energy absorption characteristics.

作為本發明之功效的第4點，係在將鉛使用於複合金屬芯之內側金屬鉛，將錫等之鉛以外的材料複合於外側金屬的情況下，可使對人體有毒性的鉛由不具毒性之外側金屬所被覆，而可改善製造過程中的處理上之安全性、對作業者之安全、衛生上的課題。 The fourth point of the present invention is that when lead is used for the metal lead inside the composite metal core, and a material other than lead such as tin is compounded on the outer metal, lead which is toxic to the human body can be used. The metal on the outside of the toxicity is coated, and the safety in handling during the manufacturing process, the safety of the operator, and the hygiene problem can be improved.

作為本發明之複合金屬芯的組合方法，係在將鉛使用於內側金屬，且將外側金屬之厚度藉由鍍敷或熔 射而形成為薄膜的情況下，複合金屬芯之機械性質就可以與內部金屬(鉛)之特性幾乎一致，且處理上表面可以實現不具毒性的金屬芯。 As a method of combining the composite metal core of the present invention, lead is used for the inner metal, and the thickness of the outer metal is plated or melted. In the case of being formed into a film, the mechanical properties of the composite metal core can be almost identical to those of the internal metal (lead), and the upper surface can be treated to achieve a non-toxic metal core.

作為本發明之功效的第5點，為含錫栓塞積層橡膠之缺點消除功效。 As the fifth point of the efficacy of the present invention, it is a disadvantage of eliminating the disadvantage of the tin-containing plug laminated rubber.

作為內置有鉛以外之金屬芯的積層橡膠隔震裝置，係有含錫栓塞積層橡膠，雖然近年來其採用實績正在伸展，但是該裝置具有如本案說明書段落[0018]至[0021]中所指稱之熱的缺點。相對於此，在將錫複合於外側金屬、將鉛複合於內側金屬的本發明之裝置中，由於可以將在錫部分所產生的熱，傳遞至熱容量較大且發熱量較低的鉛部分，所以可以抑制錫部分之溫度上升，且提高芯整體之熱容量，由於熔融溫度較高的鉛會補償錫之熱的劣化，所以當與含錫栓塞積層橡膠做比較時，就能大幅地改善因發熱而致使的裝置整體之熱的缺點，且可以消除含錫栓塞積層橡膠所具有的熱問題。 A laminated rubber vibration isolating device incorporating a metal core other than lead is a tin-containing plug-stacked rubber, and although it has been stretched in recent years, the device has a designation as described in paragraphs [0018] to [0021] of the present specification. The shortcomings of the heat. On the other hand, in the apparatus of the present invention in which tin is composited on the outer metal and the lead is composited on the inner metal, the heat generated in the tin portion can be transmitted to the lead portion having a large heat capacity and a low heat generation amount. Therefore, it is possible to suppress the temperature rise of the tin portion and increase the heat capacity of the entire core. Since the lead having a higher melting temperature compensates for the deterioration of the heat of the tin, when compared with the rubber containing the tin-containing plug, the heat generation can be greatly improved. The resulting heat of the device as a whole is disadvantageous, and the thermal problems of the tin-containing plug-laminated rubber can be eliminated.

更且，作為第6功效，在本發明中也有對複合金屬芯之平面形狀下工夫。亦即，雖然平面為正方形等之多角形的情況下可不具肋條，但是在將複合金屬芯之平面形狀形成為圓形的情況下，就要在金屬芯之外側側面及外部金屬與內部金屬之境界面設置二個以上的縱向肋條。藉此，在隔震裝置同時在水平二個方向被強制變形的情況下，尤其是在裝置上面相對於裝置底面而承受平面旋轉之激盪的情況下，也不可能在積層橡膠內部，使金屬芯發生 繞著鉛直軸之旋轉，且即便是對任何的激盪模式、尤其是圓形激盪仍可以藉由穩定的塑性變形而發揮能量吸收性能。 Further, as the sixth effect, in the present invention, there is also a work for the planar shape of the composite metal core. That is, although the plane is a polygonal shape such as a square or the like, the rib may be omitted, but in the case where the planar shape of the composite metal core is formed into a circular shape, the outer side surface of the metal core and the outer metal and the inner metal are required. The interface is provided with more than two longitudinal ribs. Thereby, in the case where the vibration isolating device is forcibly deformed in both horizontal directions, especially in the case where the device is subjected to the rotation of the plane rotation with respect to the bottom surface of the device, it is impossible to make the metal core inside the laminated rubber. occur Rotation around the vertical axis, and even for any excitation mode, especially circular oscillation, energy absorption performance can be achieved by stable plastic deformation.

又，在採用正方形(邊長D)作為金屬芯之平面形狀的情況下、採用與習知之圓形剖面(直徑d )相較為相同的平面尺寸(D=d)之情況下，由於芯的截面積成為1.27倍(=4/π)，所以謹以此也有成為衰減性能(能量吸收性能)較高之裝置的功效。 Further, in the case where a square (side length D) is used as the planar shape of the metal core, a circular cross section (diameter d) is used. In the case of the same plane size (D=d), since the cross-sectional area of the core is 1.27 times (=4/π), it is also effective as a device with high attenuation performance (energy absorption performance). .

更且，也具有經濟觀點上的功效。在現在時間點中的含錫栓塞積層橡膠的課題之一中有存在成本的問題。亦即，因用於芯中的錫之材料費用極為高價，故而含錫栓塞積層橡膠的價格變得極為高。作為本發明之複合金屬芯，係在內側金屬採用鉛、在外側金屬採用錫，且適度地限制外側金屬之錫的厚度，藉此就能夠一邊謀求毒性消除、強度改善，一邊將成本抑制在適合的水準。 Moreover, it also has an economic point of view. There is a problem of cost in one of the problems of the tin-containing plug laminated rubber in the current time point. That is, since the cost of the material used for the tin in the core is extremely high, the price of the tin-containing plug laminated rubber becomes extremely high. In the composite metal core of the present invention, lead is used for the inner metal, and tin is used for the outer metal, and the thickness of the outer metal tin is appropriately limited, whereby the elimination of the toxicity and the improvement of the strength can be achieved while suppressing the cost. The standard.

〔實施例1〕 [Example 1]

第2圖係顯示本發明之構成1及構成2的實施例1。第2圖(1)為縱向剖視圖；第2圖(2)為水平剖視圖。 Fig. 2 shows Example 1 of the configuration 1 and the configuration 2 of the present invention. Fig. 2 (1) is a longitudinal sectional view; and Fig. 2 (2) is a horizontal sectional view.

實施例1之隔震裝置，為阻尼器內置型之積層橡膠隔震裝置，其係在將薄的平板形狀之橡膠層11(彈性材料)和內部鋼板2(剛性材料)交替地積層於上下方向所得的積層橡膠體1之內部，內置有作為伴隨至少一個以上之塑性變形而發揮能量吸收功能的阻尼器機構之塑性金屬芯30所成。 The vibration isolating device of the first embodiment is a laminated rubber isolation device of a damper type, which is formed by alternately stacking a thin flat rubber layer 11 (elastic material) and an inner steel plate 2 (rigid material) in the vertical direction. The inside of the laminated rubber body 1 obtained is formed of a plastic metal core 30 as a damper mechanism that exhibits an energy absorbing function with at least one or more plastic deformations.

塑性金屬芯30，係將分別具備有降伏強度及彈性係數有所不同之兩種塑性變形能力的內側金屬32和外側金屬31在水平剖面中複合配置成同心狀所構成。且作為兩者之組合條件，係在內側金屬32之外側配置彈性係數及降伏強度比內側金屬32更高的外側金屬31並使兩者密接而一體化，藉此獲得複合金屬芯30。複合金屬芯30，係如第2圖(2)所示地使平面形狀形成為大致正方形。 The plastic metal core 30 is composed of an inner metal 32 and an outer metal 31 which are respectively provided with two kinds of plastic deformation capacities having different lodging strength and elastic modulus, and are arranged in a concentric manner in a horizontal cross section. Further, as a combination of the two, the outer metal 31 having a higher elastic modulus and a lowering strength than the inner metal 32 is disposed on the outer side of the inner metal 32, and the outer metal 31 is bonded to each other to be integrated, thereby obtaining the composite metal core 30. The composite metal core 30 is formed into a substantially square shape as shown in Fig. 2 (2).

在外側金屬31配置縱向彈性係數比內側金屬32更高、且降伏強度較高的材質，藉此可以相對於以同一平剖面尺寸之內側金屬32單獨所構成的金屬芯，比複合金屬芯之剪切剛性上升率更大幅地提高彎曲剛性上升率。結果，金屬芯之彎曲變形會變小，作為變形模式能夠使剪切變形卓越，且使剪切塑性變形穩定，使取決於塑性變形的能量吸收性能更穩定化。 The outer metal 31 is provided with a material having a higher longitudinal elastic modulus than the inner metal 32 and a higher tensile strength, whereby the metal core formed by the inner metal 32 having the same flat cross-sectional dimension can be separated from the composite metal core. The rate of increase in the rigidity of the cut increases the rate of increase in bending rigidity more significantly. As a result, the bending deformation of the metal core becomes small, and the deformation mode can make the shear deformation excellent, and the shear plastic deformation is stabilized, and the energy absorption performance depending on the plastic deformation is further stabilized.

在複合金屬芯30之上下端部附近具有厚度較厚的端部鋼板25，且在其外側具有凸緣鋼板4。 An end steel plate 25 having a relatively thick thickness is provided in the vicinity of the lower end portion of the composite metal core 30, and a flange steel plate 4 is provided on the outer side thereof.

That is, the combination 1 series sets the outer metal 31 For tin, the inner metal 32 is made of lead. In the combination 2, the outer metal 31 is made of aluminum, and the inner metal 32 is made of lead or tin. In the combination 3, the outer metal 31 is made of zinc, and the inner metal 32 is made of any of lead, tin, and aluminum. In the combination 4, the outer metal 31 is made of copper, and the inner metal 32 is made of any one of lead, tin, aluminum, and zinc.

雖然可以採用此等組合中的任一組合(其中，各材料係包含各自的合金)，但是作為代表例，則是將外側金屬31設為錫，將內側金屬32設為鉛(也包含各自的合金)的組合。 Although any combination of these combinations (each of which includes a respective alloy) may be employed, as a representative example, the outer metal 31 is made of tin and the inner metal 32 is made of lead (including each of them). A combination of alloys).

藉由以上的構成，在本發明中，係在以同一截面積來比較塑性金屬芯(複合金屬芯)30之水平剪切阻力的情況下，相對於以外側金屬31來單獨構成全剖面所得的金屬芯A之水平剪切阻力QA、和以內側金屬32來單獨構成全剖面所得的金屬芯B之水平剪切阻力QB(QB<QA)，複合金屬芯C之水平剪切阻力QC，係能夠設為金屬芯A之水平剪切阻力QA與金屬芯B之水平剪切阻力QB之間的任意強度之水平剪切阻力，且設定為QB≦QC<QA。 According to the above configuration, in the present invention, when the horizontal shear resistance of the plastic metal core (composite metal core) 30 is compared with the same cross-sectional area, the full cross section is formed separately from the outer metal 31. The horizontal shear resistance QA of the metal core A and the horizontal shear resistance QB (QB<QA) of the metal core B obtained by forming the full cross section by the inner metal 32, and the horizontal shear resistance QC of the composite metal core C are capable of The horizontal shear resistance of any intensity between the horizontal shear resistance QA of the metal core A and the horizontal shear resistance QB of the metal core B is set, and is set to QB ≦ QC < QA.

〔實施例2〕 [Example 2]

第3圖係顯示本發明之構成3的實施例，且顯示所內置的複合金屬芯之具體形狀。第3圖(1A)至(3A)是將複合金屬芯之平面形狀形成為圓形的情況；第3圖(1A)為複合金屬芯30之水平剖視圖。第3圖 (2A)為複合金屬芯30之立視圖，可看見位在外周部的縱向肋條33。第3圖(3A)為複合金屬芯30之縱向剖視圖。 Fig. 3 is a view showing an embodiment of the constitution 3 of the present invention, and shows the specific shape of the built-in composite metal core. 3 (1A) to (3A) show a case where the planar shape of the composite metal core is formed into a circular shape, and Fig. 3 (1A) is a horizontal sectional view of the composite metal core 30. Figure 3 (2A) is an elevational view of the composite metal core 30, and the longitudinal ribs 33 located at the outer peripheral portion are visible. Fig. 3 (3A) is a longitudinal sectional view of the composite metal core 30.

複合金屬芯30之縱剖面形狀，為從上端部至下端部之平面尺寸是大致相同、或些微不同的帶推拔柱狀體。將外側金屬31及內側金屬32之水平剖面形狀，設為圓形、大致正方形或八角形以下的大致正多角形之其中任一種。更且，在平面形狀為圓形的情況下，係在外側金屬31之外側面設置有四個(二個以上)的縱向肋條33，且在外側金屬31與內側金屬32之境界部嵌合並一體地設置有四個縱向槽(縱向凹凸形狀)34。 The longitudinal cross-sectional shape of the composite metal core 30 is a belt-pushing columnar body having substantially the same or slightly different planar dimensions from the upper end portion to the lower end portion. The horizontal cross-sectional shape of the outer metal 31 and the inner metal 32 is set to any one of a circular, substantially square or octagonal substantially regular polygonal shape. Further, in the case where the planar shape is circular, four (two or more) longitudinal ribs 33 are provided on the outer side surface of the outer metal 31, and the outer metal 31 and the inner metal 32 are fitted and integrated at the boundary portion of the outer metal 31. Four longitudinal grooves (longitudinal concave and convex shapes) 34 are provided.

又，第3圖(3A)係在芯之上下端部顯示用於製造積層橡膠時之懸吊作業等的芯固定用蓋構件36。該蓋構件36，係具有伴隨芯金屬於地震時變形而封鎖芯金屬朝向上部流出的「封閉功能」，並且具有：以銅或銅合金來構成該蓋構件，藉此利用發生殘留變形之後的通電來加熱、升溫芯金屬，以容易解除殘留變形的「殘留變形解除功能」，又利用該升溫、冷卻來促進伴隨塑性變形而發生的金屬結晶之再結晶化，藉此來消除塑性畸變以使金屬芯之組織恢復的「金屬組織再生功能」等。 In addition, in the third figure (3A), the core fixing cover member 36 for suspending work or the like for producing a laminated rubber is shown at the lower end portion of the core. The cover member 36 has a "closing function" in which the core metal is blocked from flowing toward the upper portion when the core metal is deformed during an earthquake, and has a cover member formed of copper or a copper alloy, thereby utilizing the energization after residual deformation occurs. By heating and heating the core metal, the "residual deformation releasing function" for easily releasing the residual deformation is utilized, and the temperature rise and cooling are used to promote recrystallization of the metal crystals accompanying the plastic deformation, thereby eliminating the plastic distortion to the metal. "Metal tissue regeneration function" restored by the core structure.

第3圖(1B)至(3B)為將複合金屬芯之平面形狀形成為大致正方形的情況；其中第3圖(1B)為複合金屬芯30之水平剖視圖；第3圖(2B)為立視圖；第3圖(3B)為縱向剖視圖。在平面形狀為正方形或多角形 的情況下，由於凸緣鋼板4會因積層橡膠之內部鋼板2、端部鋼板25的復原形狀與金屬芯外形彼此嚙合而沒有繞著鉛直軸發生旋轉偏移之虞，所以不需要外周部的縱向肋條。又，由於外側金屬31和內側金屬32也彼此嚙合，而沒有發生繞著鉛直軸之旋轉偏移之虞，所以也不需要兩個金屬境界部之縱向凹凸形狀槽。 3 (1B) to (3B) are cases in which the planar shape of the composite metal core is formed into a substantially square shape; wherein FIG. 3 (1B) is a horizontal sectional view of the composite metal core 30; and FIG. 3 (2B) is an elevational view. Fig. 3 (3B) is a longitudinal sectional view. In the shape of a plane is a square or a polygon In the case of the flange steel plate 4, since the restored shape of the inner steel plate 2 and the end steel plate 25 of the laminated rubber and the outer shape of the metal core are meshed with each other, and there is no rotational deviation around the vertical axis, the outer peripheral portion is not required. Longitudinal ribs. Further, since the outer metal 31 and the inner metal 32 are also meshed with each other without causing a rotational deviation around the vertical axis, the longitudinal uneven shape grooves of the two metal boundary portions are not required.

位在第3圖(3B)的芯之上下端部的芯固定用蓋構件之任務，係如同第3圖(3A)之說明中所記載者。 The task of the core fixing cover member located at the lower end portion of the core of Fig. 3 (3B) is as described in the description of Fig. 3 (3A).

又，第3圖(3A)及第3圖(3B)係在外側金屬31與內側金屬32之境界部顯示環槽(水平方向之凹凸形狀)35。此為在複合金屬芯被強制水平方向之變形時，用以防止在兩個金屬間發生縱向之滑動的兩個金屬之鉛直方向偏移止動件。構成為：兩種金屬複合所得的金屬芯會因形成為一體而發生畸變，藉此可使塑性變形成為均一，且可以發揮穩定的能量吸收性能。 Further, in FIGS. 3(3A) and 3(3B), a ring groove (concave-convex shape in the horizontal direction) 35 is displayed at a boundary portion between the outer metal 31 and the inner metal 32. This is a vertical offset biasing member for preventing the vertical sliding of the two metals when the composite metal core is deformed in the horizontal direction. The metal core obtained by the combination of the two metals is distorted by being integrally formed, whereby the plastic deformation is uniform and stable energy absorption performance can be exhibited.

構成6，係規定利用在外側金屬31及內側金屬32中所使用的金屬材料之熔點差異來製造第3圖所示之複合金屬芯30的方法。亦即，在外側金屬31之熔點比內側金屬32之熔點還高的情況下，可以對已事先整形成既定之尺寸、形狀的外側金屬31之內部空洞，注入在外側金屬31之熔點以下的溫度下已呈熔融狀態的內側金屬32，藉此製造複合金屬芯30。 In the configuration 6, a method of manufacturing the composite metal core 30 shown in Fig. 3 by using the difference in melting point of the metal material used in the outer metal 31 and the inner metal 32 is defined. That is, when the melting point of the outer metal 31 is higher than the melting point of the inner metal 32, the inner cavity of the outer metal 31 which has been previously formed into a predetermined size and shape can be injected at a temperature lower than the melting point of the outer metal 31. The inner metal 32, which has been in a molten state, is used to manufacture the composite metal core 30.

又反之，在外側金屬31之熔點比內側金屬32之熔點 還低的情況下，可以製作具有與外側金屬31之外面形狀相等之內面形狀的模具，且在其內部配置已事先整形的內側金屬32，並在兩者之間隙注入在內側金屬32之熔點以下的溫度下已呈熔融狀態的外側金屬31，藉此製造複合金屬芯30。 On the contrary, the melting point of the outer metal 31 is higher than the melting point of the inner metal 32. In the case where the temperature is still low, a mold having an inner surface shape equal to the outer surface shape of the outer metal 31 can be formed, and the inner metal 32 which has been previously shaped is disposed inside, and the melting point of the inner metal 32 is injected in the gap between the two. The outer metal 31 which has been in a molten state at the following temperature is used to manufacture the composite metal core 30.

〔實施例3〕 [Example 3]

第4圖係顯示本發明之實施例；其中第4圖(1A)至(2A)係將複合金屬芯之平面形狀形成為圓形的情況；第4圖(1B)至(2B)係顯示將複合金屬芯之平面形狀形成為大致正方形的情況。 Fig. 4 is a view showing an embodiment of the present invention; wherein Fig. 4 (1A) to (2A) show a case where the planar shape of the composite metal core is formed into a circular shape; and Figs. 4 (1B) to (2B) show that The planar shape of the composite metal core is formed to be substantially square.

第4圖(1A)、(1B)為複合金屬芯30之水平剖視圖；第4圖(2A)、(2B)為複合金屬芯30之立視圖。 4(1A) and (1B) are horizontal cross-sectional views of the composite metal core 30; and Figs. 4(2A) and (2B) are elevational views of the composite metal core 30.

在本實施例之隔震裝置中，係事先將內側金屬32整形成既定之尺寸、形狀，且將外側金屬浸漬於已熔融的槽內，以在內側金屬32之外表面形成外側金屬31之表面鍍敷層，藉此製造複合金屬芯30，或是，在已事先整形成既定之尺寸、形狀的內側金屬32之至少側面表面上藉由熔射噴吹外側金屬31以形成外側金屬之薄膜，藉此製造複合金屬芯30。 In the vibration isolating device of the present embodiment, the inner metal 32 is previously formed into a predetermined size and shape, and the outer metal is immersed in the molten groove to form the surface of the outer metal 31 on the outer surface of the inner metal 32. The plating layer is used to fabricate the composite metal core 30, or the outer metal 31 is sprayed by at least one side surface of the inner metal 32 which has been previously formed into a predetermined size and shape to form a film of the outer metal. Thereby, the composite metal core 30 is manufactured.

因將外側金屬31藉由鍍敷或熔射而構成作為薄膜，故而圖式上僅以外形線311來顯示，芯的大部分由內側金屬32所佔據。此時，以鉛來構成內側金屬32，以錫、或鋁及其他不具毒性之金屬來構成外側金屬31(311)且進 行被覆、塗敷，金屬芯之機械性能係能藉此一邊使其發揮鉛之特性，一邊在處理上也能實現沒有衛生、環境等問題的隔震裝置。藉此本實施例，可消除、解決含鉛栓塞積層橡膠的毒性問題。 Since the outer metal 31 is formed as a thin film by plating or spraying, it is only shown by the outline 311 in the drawing, and most of the core is occupied by the inner metal 32. At this time, the inner metal 32 is formed of lead, and the outer metal 31 (311) is formed of tin, aluminum, or other non-toxic metal. The coating and coating are applied, and the mechanical properties of the metal core can be used to achieve the characteristics of lead, and the vibration isolation device without problems such as hygiene and the environment can be realized in the treatment. By this embodiment, the toxicity problem of the lead-containing plug laminated rubber can be eliminated and solved.

在本實施例中，由於外側金屬係構成作為薄膜，所以藉由外層金屬而致使的阻力變得極為小，而複合金屬芯C之阻力QC會變成大概接近內側金屬B之阻力QB的值(QC≒QB)。 In the present embodiment, since the outer metal is configured as a film, the resistance caused by the outer metal is extremely small, and the resistance QC of the composite metal core C becomes a value close to the resistance QB of the inner metal B (QC). ≒QB).

〔實施例4〕 [Example 4]

第5圖係具體顯示藉由本發明之構成1及構成2所構成的兩種金屬之複合功效。將複合金屬芯30之外側金屬31設為錫、將內側金屬32設為鉛而組合在一起所得之情況下的複合金屬芯30之平均剪切降伏應力強度T，是顯示如何按照複合金屬芯30之直徑dp與外側金屬31之厚度t1之比率2t1/dp而變化。 Fig. 5 specifically shows the composite effect of the two metals composed of the composition 1 and the composition 2 of the present invention. The average shear stress stress T of the composite metal core 30 in the case where the outer metal 31 of the composite metal core 30 is made of tin and the inner metal 32 is made of lead is a function of how to follow the composite metal core 30. The ratio of the diameter dp to the thickness t1 of the outer metal 31 varies by 2t1/dp.

亦即，橫軸2t1/dp=0的情況下之水平剪切阻力(平均剪切應力強度)T係與內側金屬32之鉛的剪切降伏應力強度T=8(N/mm2)一致。在將實施例3之外側金屬31藉由鍍敷或熔射而構成作為薄膜的情況下，係大致對應此狀態。 That is, the horizontal shear resistance (average shear stress intensity) T in the case where the horizontal axis 2t1/dp=0 is consistent with the shear stress strength T=8 (N/mm 2 ) of the lead of the inner metal 32. When the outer metal 31 of the third embodiment is formed into a thin film by plating or spraying, it substantially corresponds to this state.

如同第5圖所示，隨著外側金屬31之厚度變厚，複合金屬芯30之水平剪切阻力就會上升，當橫軸變成2t1/dp=1時，複合金屬芯30之水平剪切阻力(平均剪切 應力強度)T，就會與外側金屬31、即以錫構成全剖面的情況之剪切降伏應力強度T≒15(N/mm2)一致。如同本圖所示，在本發明中，藉由兩種金屬之組合方法，只要在兩個金屬之水平剪切阻力之間，則可以將平均剪切應力強度調整在任意的強度。另外，該栓塞，在錫與鉛之組合中，即便複合金屬芯30之平面形狀為圓形或正方形仍為相同的曲線，更且即便是在多角形的情況下，外側金屬31和內側金屬32仍為同形狀且只要外側金屬31之厚度t1為均一則與該曲線一致。 As shown in Fig. 5, as the thickness of the outer metal 31 becomes thicker, the horizontal shear resistance of the composite metal core 30 rises, and when the horizontal axis becomes 2t1/dp = 1, the horizontal shear resistance of the composite metal core 30 The (average shear stress intensity) T is in agreement with the shear stress strength T ≒ 15 (N/mm 2 ) of the outer metal 31, that is, the case where the whole cross section is made of tin. As shown in the figure, in the present invention, by combining the two metals, the average shear stress intensity can be adjusted to an arbitrary strength as long as the shear resistance is between the two metals. In addition, the plug, in the combination of tin and lead, even if the planar shape of the composite metal core 30 is circular or square, the same curve, and even in the case of a polygon, the outer metal 31 and the inner metal 32 It is still the same shape and conforms to the curve as long as the thickness t1 of the outer metal 31 is uniform.

〔實施例5〕 [Example 5]

第6圖係顯示將外側金屬31設為錫、將內側金屬32設為鉛之情況下的複合金屬芯30之實際尺寸(複合金屬芯(栓塞)直徑dp)與水平剪切阻力Qd之關係。金屬芯之平面形狀為圓形的情況。 Fig. 6 is a view showing the relationship between the actual size (composite metal core (plug) diameter dp) of the composite metal core 30 and the horizontal shear resistance Qd when the outer metal 31 is made of tin and the inner metal 32 is made of lead. The case where the planar shape of the metal core is circular.

栓塞直徑dp，係設為 100mm至 300mm之範圍，且為複數個曲線當中的最下段之線是以鉛構成全剖面的情況、而最上段之線是以錫構成全剖面的情況之水平剪切阻力。可明白即便是在直徑300mm 的情況下，仍可以藉由僅將外層金屬31之錫的厚度設為t1=10mm至50mm左右，而極有效率地使水平剪切阻力Qd上升。 Embolization diameter dp, set to 100mm to The range of 300 mm is the case where the lowermost line among the plurality of curves is a case where the full profile is formed by lead, and the line of the uppermost segment is the horizontal shear resistance in the case where the whole profile is made of tin. Can understand even in the diameter of 300mm In the case of the outer layer metal 31, it is possible to increase the horizontal shear resistance Qd extremely efficiently by setting only the thickness of the tin of the outer layer metal 31 to about t1 = 10 mm to 50 mm.

〔實施例6〕 [Example 6]

第7圖係與第6圖同樣地顯示將外側金屬31 設為錫、將內側金屬32設為鉛所組合之複合金屬芯30，並將該複合金屬芯30設成正方形之情形下，複合金屬芯30(栓塞)之邊長dp與水平剪切阻力Qd之關係。 Fig. 7 shows the outer metal 31 as in the sixth drawing. When the composite metal core 30 is made of tin and the inner metal 32 is made of lead, and the composite metal core 30 is square, the side length dp of the composite metal core 30 (plug) and the horizontal shear resistance Qd are set. Relationship.

正方形栓塞之尺寸係將邊長dp設為100mm至300mm之範圍，且為最下段之線是以鉛構成全剖面的情況、而最上段之線是以錫構成全剖面的情況之水平剪切阻力。與第6圖同樣地顯示可以藉由僅將外層金屬31之錫的厚度設為t1=10mm至50mm，而極有效率地使水平剪切阻力Qd上升，又即便是相同的外形尺寸仍可以藉由形成為正方形，來使水平剪切阻力Qd變得比圓形平面更相當大。 The size of the square plug is set to a range of 100 mm to 300 mm, and the line of the lowermost line is a full profile of lead, and the line of the uppermost stage is a horizontal shear resistance of a full profile of tin. . As shown in Fig. 6, it can be shown that the horizontal shear resistance Qd can be extremely efficiently increased by merely setting the thickness of the tin of the outer layer metal 31 to t1 = 10 mm to 50 mm, and even the same outer shape can be borrowed. By forming into a square, the horizontal shear resistance Qd becomes considerably larger than the circular plane.

〔實施例7〕 [Example 7]

第8圖係顯示藉由將金屬芯複合化而使金屬芯之彎曲剛性EI和剪切剛性GA上升的程度。所複合的金屬，係與前例同樣地顯示將外側金屬31設為錫、將內側金屬32設為鉛並組合在一起所得的情況，且顯示與以鉛構成全剖面的情況相對的剛性之比率。 Fig. 8 shows the degree of increase in the bending rigidity EI and the shear rigidity GA of the metal core by combining the metal cores. In the same manner as in the previous example, the metal to be composited is obtained by combining the outer metal 31 with tin and the inner metal 32 with lead, and exhibiting a ratio of rigidity to a case where the full cross section is formed of lead.

雖然複合金屬芯30之平面形狀係形成為圓形，且將複合金屬芯30(栓塞)之直徑dp設為 100mm至 300mm之範圍，但是該栓塞並不依存於芯尺寸，而是無論在哪一個尺寸都是相同的。 Although the planar shape of the composite metal core 30 is formed into a circular shape, the diameter dp of the composite metal core 30 (plug) is set to 100mm to The range of 300 mm, but the plug does not depend on the core size, but the size is the same regardless of the size.

在複數條線當中的最下段之線(A1/A0=0)是以鉛構成全剖面的情況下，將該剛性設為基準值=1。最上段之線(A1/A0=1)是以錫構成全剖面的情況之剛性，彎曲剛性 EI的上升率係一致於錫與鉛之縱向彈性係數之比率，而剪切剛性GA之上升率係一致於錫與鉛之剪切彈性係數之比率。中間的複數條線，係將外側金屬31(錫)之面積A1對芯之總截面積A0的比率A1/A0之值顯示作為參數。 When the lowermost line (A1/A0 = 0) among the plurality of lines is a full cross section of lead, the rigidity is set to a reference value of 1. The uppermost line (A1/A0=1) is the rigidity of the case where the whole cross section of tin is formed, and the bending rigidity The rate of increase of EI is consistent with the ratio of the longitudinal elastic modulus of tin to lead, while the rate of increase of shear stiffness GA is consistent with the ratio of the shear modulus of tin to lead. The plurality of lines in the middle are shown as the parameters of the ratio A1/A0 of the area A1 of the outer metal 31 (tin) to the total cross-sectional area A0 of the core.

如同根據兩個圖式之比較可明白般，在外側金屬31之面積為相同的情況下，非常明白彎曲剛性之上升率變得比剪切剛性之上升率更大。本發明的重點之一係在於該彎曲剛性之上升率變得比剪切剛性之上升率更高。 As can be understood from the comparison of the two drawings, in the case where the area of the outer metal 31 is the same, it is understood that the rate of increase of the bending rigidity becomes larger than the rate of increase of the shear rigidity. One of the gist of the present invention is that the rate of increase of the bending rigidity becomes higher than the rate of increase of the shear rigidity.

〔實施例8〕 [Example 8]

第9圖係將複合金屬芯30中的彎曲剛性EI與剪切剛性GA之上升率，於橫軸顯示作為外側金屬31之厚度t1對圓形芯之直徑dp的比率2t1/dp。所複合的金屬，係與前例同樣地在將外側金屬31設為錫、將內側金屬32設為鉛並組合在一起所得的情況下，顯示作為與以鉛構成全剖面的情況之剛性(基準值=1)相對的剛性之上升率。 In the ninth graph, the rate of increase of the bending rigidity EI and the shear rigidity GA in the composite metal core 30 is shown on the horizontal axis as the ratio 2t1/dp of the thickness t1 of the outer metal 31 to the diameter dp of the circular core. In the case where the outer metal 31 is made of tin and the inner metal 32 is made of lead and is combined, the rigidity of the metal is shown as a reference value. =1) Relative stiffness rise rate.

如同根據該栓塞可明白般，複合金屬芯30之剛性上升率係在2t1/dp=0~0.7之範圍內，彎曲剛性之上升率會超過剪切剛性之上升率，而在2t1/dp≒0.7時則會逆轉。亦即，在將複合金屬芯30之外側金屬31設為錫、將內側金屬32設為鉛所構成的情況下，外側金屬31(錫)之厚度應設為t1/dp=0~0.35之範圍。 As can be understood from the plug, the rigidity rise rate of the composite metal core 30 is in the range of 2t1/dp=0~0.7, and the rate of increase of the bending rigidity exceeds the rate of increase of the shear rigidity, and at 2t1/dp≒0.7. It will be reversed. In other words, when the outer metal 31 of the composite metal core 30 is made of tin and the inner metal 32 is made of lead, the thickness of the outer metal 31 (tin) should be set to a range of t1/dp=0 to 0.35. .

在此條件之範圍內，本發明之複合金屬芯30係成為容易使剪切變形卓越的變形模式之金屬芯，且可以期待發揮穩定的能量吸收性能。 Within the scope of the above-described conditions, the composite metal core 30 of the present invention is a metal core which is a deformation mode which is excellent in shear deformation, and is expected to exhibit stable energy absorption performance.

另外，該栓塞，係在錫與鉛之組合中，即便複合金屬芯30之平面形狀為圓形或正方形仍為相同的曲線，更且即便是在多角形的情況下，外側金屬31和內側金屬32仍為同形狀且外側金屬31之厚度t1仍為均一，只要對剖面中心軸(中立軸)為對稱形狀則與該曲線一致。 In addition, the plug is in a combination of tin and lead, even if the planar shape of the composite metal core 30 is circular or square, the same curve, and even in the case of a polygon, the outer metal 31 and the inner metal 32 is still of the same shape and the thickness t1 of the outer metal 31 is still uniform, as long as the central axis of the section (the neutral axis) is symmetrical and conforms to the curve.

〔實施例9〕 [Example 9]

當同時考慮以上之第6圖、第7圖、第9圖時，就明白本發明係具有以下優異的功效。亦即，當以將外側金屬31設為錫、將內側金屬32設為鉛來構成複合金屬芯30的情況加以說明時，只要將外側金屬31之錫的厚度設為10mm至20mm左右，就可以使芯之水平剪切阻力相當地上升，同時可以使芯之彎曲剛性大幅上升(相對於平均的芯尺寸dp=200mm，成為2t1/dp≒0.1~0.2)，並成為剪切變形卓越型的變形模式，且發揮穩定的能量吸收特性。 When considering Fig. 6, Fig. 7, and Fig. 9 above, it is understood that the present invention has the following excellent effects. In other words, when the outer metal 31 is made of tin and the inner metal 32 is made of lead to form the composite metal core 30, the thickness of the tin of the outer metal 31 can be set to about 10 mm to 20 mm. The horizontal shear resistance of the core is increased considerably, and the bending rigidity of the core can be greatly increased (2t1/dp ≒ 0.1 to 0.2 with respect to the average core size dp=200 mm), and the deformation is excellent in shear deformation. Mode and exert stable energy absorption characteristics.

此時，由於芯整體可以利用內側金屬32之鉛(鉛之面積為整體的90%至81%)的功效來確保較大的熱容量，所以在錫部分所上升的溫度可快速地傳遞至鉛部分，且可抑制芯整體的溫度上升。結果，在芯整體由錫所構成的含錫栓塞積層橡膠中，雖然在反覆多次較大之變形 的嚴酷之地震輸入的情況下，水平剪切阻力會因錫栓塞之溫度上升而急劇地降低，且在最差的情況有熔融的可能性，但是在本發明之複合金屬芯30中可大幅地改善、消除因該溫度上升而致使的水平剪切阻力之降低或芯本身之熔融的危險性。 At this time, since the core as a whole can utilize the effect of the lead of the inner metal 32 (the area of lead is 90% to 81% of the whole) to ensure a large heat capacity, the temperature rising in the tin portion can be quickly transmitted to the lead portion. Moreover, the temperature rise of the entire core can be suppressed. As a result, in the tin-containing plug-laminated rubber composed of tin as a whole, although a large deformation is repeated many times In the case of severe earthquake input, the horizontal shear resistance is drastically lowered due to the temperature rise of the tin plug, and there is a possibility of melting in the worst case, but it can be greatly improved in the composite metal core 30 of the present invention. The risk of a decrease in the horizontal shear resistance caused by the temperature rise or the melting of the core itself is improved or eliminated.

〔實施例10〕 [Example 10]

第10圖係顯示內置本發明之複合金屬芯30的積層橡膠隔震裝置所具有的功效之一的實施例。 Fig. 10 is a view showing one of the effects of the laminated rubber vibration isolating device incorporating the composite metal core 30 of the present invention.

第10圖(1)係顯示積層橡膠體1在箭頭5之方向接受水平剪切變形之狀態(變形1)的縱向剖視圖。內置芯3係按照積層橡膠體1之水平變形而如圖所示地變形，且相對於芯之下端部37，芯之上端部38係只要平面位置與積層橡膠之水平變形量相同就會成為已水平偏移的位置。 Fig. 10 (1) is a longitudinal cross-sectional view showing a state (deformation 1) in which the laminated rubber body 1 is subjected to horizontal shear deformation in the direction of the arrow 5. The built-in core 3 is deformed as shown in the figure according to the horizontal deformation of the laminated rubber body 1, and the upper end 38 of the core is the same as the horizontal deformation of the laminated rubber as long as the horizontal position of the laminated rubber is the same as the lower end portion 37 of the core. The position of the horizontal offset.

在此狀態之後，當積層橡膠上端38之變形前進至與箭頭5之方向(變形1)相差90°的正交方向6時，作用於第10圖(2)之箭頭6之方向的力(圖中央之箭頭)就會成為使芯3對芯之下端部37旋轉的力矩(扭力)，而芯3則繞著鉛直軸如箭頭8所示地旋轉。當芯3以繞著鉛直軸之旋轉變形來追蹤積層橡膠體之水平變形時，就不會在芯本身發生塑性剪切變形，結果，無法發揮芯之能量吸收性能。 After this state, when the deformation of the upper end 38 of the laminated rubber advances to the orthogonal direction 6 which is 90° out of the direction of the arrow 5 (deformation 1), the force acting in the direction of the arrow 6 of Fig. 10 (2) (Fig. The central arrow) becomes the moment (torque) that causes the core 3 to rotate against the lower end portion 37 of the core, and the core 3 rotates about the vertical axis as indicated by the arrow 8. When the core 3 is subjected to the rotational deformation around the vertical axis to track the horizontal deformation of the laminated rubber body, plastic shear deformation does not occur in the core itself, and as a result, the energy absorption performance of the core cannot be exhibited.

在本發明中，在將複合金屬芯30之平面形狀形成為正方形等之多角形、或圓形的情況下，係在金屬芯 之外側側面及外部金屬與內部金屬之境界面設置二個以上的縱向肋條。藉此，在隔震裝置同時在水平二方向被強制變形的情況下，尤其即便是在接受如裝置上面相對於裝置底面而俯視旋轉之箭頭7之激盪的情況下，金屬芯30也不可能在積層橡膠內部，發生繞著鉛直軸之旋轉，且具備無論是對任何的激盪、尤其是圓形激盪都可以藉由穩定的塑性變形而發揮能量吸收性能的優異功效。 In the present invention, in the case where the planar shape of the composite metal core 30 is formed into a polygonal shape such as a square or the like, or a circular shape, it is attached to the metal core. Two or more longitudinal ribs are disposed on the outer side surface and the interface between the outer metal and the inner metal. Thereby, in the case where the vibration isolating device is forcibly deformed in the horizontal direction at the same time, in particular, even in the case of receiving the oscillation of the arrow 7 which is rotated in a plan view with respect to the bottom surface of the device, the metal core 30 is impossible. The inside of the laminated rubber is rotated around the vertical axis, and has an excellent effect of exhibiting energy absorption performance by stable plastic deformation regardless of any vibration, especially circular vibration.

如同以上所述，在內置本發明之複合金屬芯30的積層橡膠中，係可以將單一金屬所無法達成的芯之水平剪切阻力設定在適當的水準，同時可以發揮穩定的能量吸收性能，且能夠大幅地改善至今的阻尼器內置型之積層橡膠的性能、可靠度。 As described above, in the laminated rubber in which the composite metal core 30 of the present invention is incorporated, the horizontal shear resistance of the core which cannot be achieved by a single metal can be set to an appropriate level, and stable energy absorption performance can be exerted, and It is possible to greatly improve the performance and reliability of the laminated rubber of the damper built-in type to date.

尤其是經歷過2011年東北地方太平洋海岸地震(M9.0)，至今已認識到M9級的超巨大地震即便是在日本也是具有現實性的，在假定長周期、長時間持續的嚴酷地震運動或水平二方向之嚴酷的輸入地震運動的情況下，本發明之隔震裝置可期待帶來較大的貢獻功能。 In particular, after experiencing the 2011 Northeast Pacific Coastal Earthquake (M9.0), it has been recognized that the M9-class super-large earthquake is realistic even in Japan, assuming a long-period, long-lasting severe earthquake or In the case of severe input seismic motion in the horizontal direction, the vibration isolating device of the present invention can be expected to bring a large contribution function.
