本文研究对象当户外使用聚硫与硅酮密封材料时,活动的接缝装置中封缝接缝的行为。试验器制成能产生与实际建筑物中相同的接缝活动。同时,研究了用于测量接缝活动与密封材料应力的装置。这些试验器与装置露天安放于横滨的一座七层建筑物屋顶之上,分别以五个方向置放,垂直朝向东、南、西、北,以及平行朝天。对此测量在户外进行了两年。本文描述观测到的封缝接缝的行为,即移动的幅度与速度,以及密封材料的应力;探讨朝向或角度、季度与密封材料性能对封缝接缝行为的效应。
This article examines the behavior of sealed seams in active joint devices when using polysulfide and silicone sealing materials outdoors. Testers are made to produce the same seam activities as in actual buildings. At the same time, a device for measuring the joint movement and the stress of the sealing material was studied. These testers and devices are placed on the roof of a seven-story building in Yokohama and placed in five directions, facing east, south, west, and north, and in parallel. This measurement was performed outdoors for two years. This article describes the behavior of the seams observed, namely the magnitude and speed of the movement, and the stress of the sealing material; and the effect of the orientation or angle, quarter, and the performance of the sealing material on the sealing seams.
