關鍵詞:設備物、矽力康固定、黏著力、強度。
本研究探討一個對於靠牆設備物的固定方式:「以矽力康黏著設備物之固定機制」。其基本原理為:將流體狀態的矽力康施打於設備物邊緣與牆壁接觸的交界地方,待其固化後,利用矽力康和外牆表面材質的黏著力及矽力康本身的強度,將設備物固定於建築物室內牆壁表面,達到抗震的效果。相較於其他傳統固定方式之優點為:矽力康容易施打與清除、不需破壞牆體或設備物本身,且價格便宜。
本研究實驗探討將矽力康應用在水平方向與垂直方向的設備物固定上,並藉全尺寸實驗裝置對其做橫向和縱向兩方向的耐震性能測試,綜合結果得到以下特性:
一、利用矽力康來固定,不增加設備物重量,故無慣性力與樓板承載力之問題;被固定的設備物與牆壁表面沒有接觸,故亦無彎矩與背擋摩擦力之問題。
二、設備物以矽力康固定後,可抵抗較大的地表加速度,降低設備物產生初始的位移以及傾倒的機率。
三、設備物以矽力康固定於牆面上,矽力康黏著設備物所能提供之強度與膠道長度成正比,所能抵抗的橫向地震力與縱向地震力間之比值,亦趨於簡單的比例常數;再配合安全系數的修正,可將有關的矽力康膠道強度設計計算方法整理成一簡便之線性公式。
四、可藉改變矽力康膠道長度和斷面大小,來控制設備物於建築物的不同樓層上,被固定後所能承受的地震力大小,以確保設備物的耐震安全。
由實驗結果可知,此種利用矽力康來固定設備物的方式,不僅簡易操作,預算低廉,也能達到固定設備物的功能。
Keywords: cabinets, silicone glazing, adhesion force, strength
This study suggests a new seismic resistant measure on Operational and Functional Components (OFC) such as cabinets: 「To strengthen the seismic capacity of cabinets by silicone glazing」. A new fixture technique is developed by adhering cabinets to a neighboring wall with liquid silicone. When solidified by current, the silicone glazing produce sufficient adhesion force which helps to attach the cabinets to the backing wall, thus the cabinets is anchored. The advantage of silicone glazing is easy to apply, easy to remove, no damage on the wall, and low expense. Besides, problems caused by traditional approach can be avoided.
This research developed a simplified equation for silicone strengthening based on the welding design concept for fillet welds. Experimental study to calibrate the calculated strength and investigate the macroscopic behavior of silicon gluing lines is also performed.
After the tests, several properties of cabinets fixed by silicone glazing were found:
1.Adhesion force won’t produce inertia force to the cabinets nor extra bearing weight on the wall.
2.To prevent cabinets from overturning or sliding, the stronger the adhesion force is used, the more seismic capacity the cabinets have.
3.Simple equations derived from the fillet weld design are proposed for the silicon application since both of them have similar geometric layout. The practical value of parameters can be adjusted to correct the variation from proposed equations.
4.Different leg sizes and different lengths of the silicon run were chosen in order to verify the strength of different silicon sizes. The ultimate strength increased in most of the tests by increasing the leg size and the length of the glue.
In conclusion, silicon connection is convenient glue for seismic protection for light-weight OFC placed next to a wall. The strength of silicon is demonstrated with test results and simple equations are derived for application.
