Description
本發明係一種滑動隔震裝置;特別關於一種一般建築物構造之防止振動或震動之裝置及機械工程元件之減震器,可以使用支撐之方式,或是以懸吊之方式來承受所需保護結構物之重量,並可同時隔離震動能量之導入,防止結構物受到破壞,達到保護結構物之功效。 The invention relates to a sliding isolation device; in particular to a device for preventing vibration or vibration of a general building structure and a shock absorber for mechanical engineering components, which can be supported by means of suspension or suspended. The weight of the structure can simultaneously isolate the introduction of vibration energy, prevent the structure from being damaged, and achieve the effect of protecting the structure.
如第1圖所示為習知之摩擦單擺隔震支承(10),摩擦單擺隔震支承(10)使用球面滑動之方式達到隔離震動之功效,但其機構皆為接觸之方式而非連結方式組裝,因此必須使用臨時固定裝置加以固定,於安裝完成後才可拆除,以避免零件脫離散落,機構之穩定性與安全性欠佳。 As shown in Figure 1, the conventional friction single pendulum isolation support (10), the friction single pendulum isolation support (10) uses the spherical sliding method to achieve the effect of isolation vibration, but the mechanism is the way of contact rather than the link The method is assembled, so it must be fixed by temporary fixing device, and can be removed after the installation is completed to avoid the parts from falling off, and the stability and safety of the mechanism are not good.
摩擦單擺隔震支承(10)如受到垂直震動之作用時,組件易產生跳脫,一旦發生零件脫離之情形,不但無法發揮隔震之功效,更可能瞬間造成基礎支撐高度不均而使結構傾斜產生破壞倒塌,反而比非隔震建築更加危險,大大降低隔震支承之實用性與安全性。 When the friction single pendulum isolation bearing (10) is subjected to vertical vibration, the component is prone to tripping. Once the part is detached, the function of the isolation can not be exerted, and the height of the basic support is uneven. Tilting causes damage and collapse, but it is more dangerous than non-isolated buildings, greatly reducing the practicality and safety of the isolation support.
另外裝設摩擦單擺隔震支承(10)之隔震結構如受較大之側向力作用時,若無抗拉之裝置承受拉力,隔震結構則易產生傾倒翻覆之危險。 In addition, if the vibration isolation structure of the friction single pendulum isolation bearing (10) is subjected to a large lateral force, if the tension-free device is subjected to the tensile force, the isolation structure is liable to cause the risk of dumping and overturning.
第2圖所示之隔震裝置,使用滑動子或滾動子於板材上軌道之作動方式達到隔震之功效。 The isolation device shown in Fig. 2 uses the action of the slider or the roller on the track on the plate to achieve the effect of vibration isolation.
圓弧線軌道之隔震裝置使用滑動方式或滾動方式作動時,使用單一圓弧單一接觸之方式,也就是靜止時,接觸點位於圓弧之最低點,此為穩定之位置,但在圓弧之最低點時,反作用力為垂直向,無水平向之分量,尤其使用滾動方式,靜止時受到輕微之水平力時就可能作動,對於建築結構或置放物品之隔震平台將產生使用上之困擾,例如建築結構如受到風力時就可能產生搖晃,對於居民可能產生暈眩的感覺。 When the vibration isolation device of the circular arc track is operated by sliding mode or rolling mode, a single arc single contact method is used, that is, when the vehicle is stationary, the contact point is located at the lowest point of the arc, which is a stable position, but in the arc At the lowest point, the reaction force is vertical, and there is no horizontal component. Especially when using the rolling method, it may be activated when it is subjected to a slight horizontal force at rest. The isolation structure for the building structure or the placed items will be used. Troubles, such as building structures that may be shaken when subjected to wind, may cause dizziness to residents.
本發明在於使隔震裝置上單一軌道上有兩點之接觸位置,兩點接觸位置之重力之反作用力之水平向分量可達平衡,對於平衡位置產生較佳之約束力,可較快速與精準回歸定位,並可將載重分散至兩處,而不會集中於一處,因而較容易產生應力集中之情形。 The invention is to make the contact position of the two points on the single track on the seismic isolation device, and the horizontal component of the reaction force of the gravity of the two contact positions can reach equilibrium, and the better binding force for the equilibrium position can be returned quickly and accurately. The positioning and the load can be dispersed to two places without being concentrated in one place, so that stress concentration is more likely to occur.
如第3圖所示之滑動隔震裝置(20)中,活動子(50)為滑動方式作動之滑動子;連結器(60)兩端部位以鉸接方式連結活動子(50);鉸接基座(40)以鉸接方式連結連結器(60)之中心;軌道基座(30)設有圓弧線軌道(31);將2組活動子(50)以鉸接方式連結於連結器(60)兩端部位上,活動子(50)可相對於連結器(60)轉動;將連結器(60)之中心以鉸接方式連結於鉸接基座(40)上,連結器(60)可相對於鉸接基座(40)擺動;將2組活動子(50)設置於軌道基座(30)之同一圓弧線軌道(31)上,鉸接基座(40)與軌道基座(30)之間產生單向水平平行之相對移動時,連結器(60)會相對於鉸接基座(40)擺動,使軌道基座(30)之同一圓弧線軌道(31)上之2組活動子(50)可同時產生滾動,或滑動。 In the sliding isolation device (20) shown in Fig. 3, the movable member (50) is a slide-operated slider; the two ends of the connector (60) are hingedly coupled to the movable member (50); (40) articulating the center of the connector (60); the track base (30) is provided with a circular arc track (31); and the two sets of movable members (50) are hingedly coupled to the connector (60) At the end portion, the movable member (50) is rotatable relative to the connector (60); the center of the connector (60) is hingedly coupled to the hinge base (40), and the connector (60) is relative to the hinge base The seat (40) swings; two sets of movable members (50) are disposed on the same circular arc track (31) of the track base (30), and a single is generated between the hinge base (40) and the track base (30). When moving horizontally in parallel, the connector (60) will swing relative to the hinge base (40) so that the two sets of movable members (50) on the same circular arc track (31) of the track base (30) can At the same time produce scrolling, or sliding.
