    • PROBLEM TO BE SOLVED: To provide a heat-insulation and vibration-proof suspension tool capable of suppressing vibrations from an upper fastening object, preventing dew condensation by heat insulating the upper fastening object and a lower fastening part, facilitating construction work and lowering a manufacturing cost.SOLUTION: The heat insulation and vibration-proof suspension tool includes: a nut 2 and/or a bolt 5 connected to upper and lower fastening objects; a vibration-proof elastic member 3 which incorporates the nut 2 and/or a head part 51 of the bolt 5 and has elasticity; and a frame-like reinforcing member 4 which surrounds and reinforces the vibration-proof elastic member 3 in a frame shape. The vibration-proof elastic member 3 includes: an upper side housing groove 33 and a lower side housing groove 34 for housing the nut 2 or the head part 51 of the bolt 5; an upper side bolt hole 37 communicated with the upper side housing groove 33 from an upper end face 35; a lower side bolt hole 38 communicated with the lower side housing groove 34 from a lower end face 36; and a contact prevention part 39 for preventing the contact of the bolts that pass through the upper side bolt hole 37 and the lower side bolt hole 38 and face each other.
    • 要解决的问题:提供一种能够抑制来自上部紧固件的振动的隔热和防振悬挂工具,通过将上部紧固物体和下部紧固部件进行绝热来防止结露,促进施工作业并降低制造 成本。解决方案:隔热和防振悬挂工具包括:连接到上下固定物体的螺母2和/或螺栓5; 结合螺栓5的螺母2和/或头部51并具有弹性的防振弹性构件3; 以及框架状的加强构件4,其围绕并加强框架形状的防振弹性构件3。 防振弹性构件3包括:用于容纳螺栓5的螺母2或头部51的上侧容纳槽33和下侧容纳槽34; 从上端面35与上侧容纳槽33连通的上侧螺栓孔37; 与下侧容纳槽34从下端面36连通的下侧螺栓孔38; 以及用于防止通过上侧螺栓孔37和下侧螺栓孔38的螺栓彼此面对的接触的防止接触部39。
