Title:
FLEXIBLE JOINT
Document Type and Number:
Japanese Patent JP3527964
Kind Code:
B2
Abstract:
PURPOSE: To obtain a spring characteristic and a water stop performance corresponding to drawing force at the time of pressure contact in a flexible joint used for the joint part of a concrete case or the like by forming the center part in the width direction of cross section of a body part into a laminated part with laminated material bonded in the laminated state to elastic material, and forming both side parts into elastic body parts.
CONSTITUTION: In the body part 5 of a flexible joint, the center part leaving out both side parts in the width direction of cross section is formed into a laminated part 6 laminated into a laminated body, and elastic body parts 7 made of rubber or the like are formed on both side parts. The laminated part 6 is of such structure that the laminated body 8 of natural fiber, synthetic fiber, metal mesh, or the like is adhesively embedded in elastic material and that high spring force can be displayed in order to correspond to pressure contact force. The body part 5 is also provided with a soft noze 9 lower in height at the center part than the outer part and lower in Young's modulus than the body part 5. A fastening part 10 with a bolt locking hole and with reinforcing material 11 such as an iron plate embedded therein is formed at the bottom part of the body part 5. The joint is bolt-fixed to the end face of a connected case body at this fastening part 10.
