。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is used as a flexible pipe joint for dark piping between the foundation of a seismically isolated building and the building, and is capable of following any large displacement. This invention relates to a new flexible pipe joint for seismic isolation.

（１） できまる。Conventional bellows-shaped flexible pipe joints maintain their flexibility through the balance of the bellows, so they buckle when internal pressure is applied, and it is also possible to simply bend a rod-shaped pipe joint and use it as a flexible pipe joint. In use, it buckles due to large bending with respect to the required space, so a long joint is required for the space to be fixed, and furthermore, installation requires a lot of manpower.In view of the above, the present invention is exempt. The purpose of this invention is to provide a flexible pipe joint for seismic isolation that can be used in earthquake buildings, etc. and is flexible enough to follow any large displacement and is easy to construct. Generally, the center of displacement required for a flexible pipe joint for seismic isolation is shown in Figure 3. If the length of the attachment part is υ, the required length C1) of the flexible pipe joint is t, e.・・・・・・・・・

継手に関するものである。The present invention provides a flexible pipe joint molded product in which a rubber layer is provided as the innermost layer and an outermost layer, and a reinforcing layer is provided in the middle layer, and a laminated product is finished into a flexible linear pipe joint of a predetermined length. The flexible straight pipe joint is then semi-vulcanized, then curved until the straight length of the flexible straight pipe joint becomes the installation length (L) of the flexible pipe joint, and then additional vulcanization is applied to fix the curve. This invention relates to a flexible pipe joint for seismic isolation.

Furthermore, a reinforcing layer preferably made of synthetic fiber is provided inside the outermost layer and the innermost layer.

果的である。(See Figure 1) The minimum required length (12) of the flexible pipe joint for seismic isolation shown in the +1+ formula above is the known length when L is designed as the space in the foundation of the building. Therefore, the size of g is determined once r is determined, but the size of g depends on the size of the earthquake (' is not necessarily constant, but usually the value of O is aOO ~ 4
Approximately 0 rm is required. Therefore, according to this criterion, 1. is decided, and l as /, 'At't is not used from the final ceremony, l! The larger the value, the better and more effective.
