Description

  The present invention relates to a joining device, and more specifically, for example, in a displacement amplification type vibration damping device incorporated in a frame of a building or a structure, for connecting a brace member to a corner joining member so as to be rotatable within a predetermined angle range The present invention relates to a joining apparatus.

  As one of the vibration damping technologies, a displacement amplification type vibration damping device is known which is incorporated into a building or structure frame and amplifies the displacement generated between layers in the event of an earthquake and the like and transmits it to a damper (for example, a patent Reference 1).

  In such a displacement amplification type vibration damping device, the brace member is rotatably connected to the corner portion of the frame. Specifically, a bracket for connecting a metal fitting of the brace member is attached in advance to the corner portion, and the bracket is connected to the bracket via a pin.

However, construction errors occur in the construction of new buildings and structures. When such a construction error occurs, it may become impossible to assemble, for example, it becomes impossible to insert a pin into the connecting portion between the metal joint and the bracket. For this reason, conventionally, the position of the pin has been forcibly adjusted by inserting a liner or the like between the joint hardware. However, adjustment is difficult, and an excessive force may be applied to the member, and further, there is a problem that costs are also increased.

  1 is an axial sectional view showing an embodiment of the present invention, FIG. 2 is an exploded perspective view, and FIG. 3 is a sectional view taken along line AA in FIG. This embodiment is an example in which the present invention is applied to the joining of the brace member 1 and the corner fitting 2 in the displacement amplification type vibration damping device. The brace member 1 corresponds to a movable side member, and the corner joint hardware 2 is disposed at a corner portion of the frame and corresponds to a fixed side member.

  The joining apparatus includes a hammer type joint member 3, a spherical member 4, a spherical seat 5, and a fixed hardware 6. The hammer type joint member 3 has a shaft portion 7, and a cylindrical hammer portion 8 is formed at the tip of the shaft portion 7 so as to be T-shaped. The shaft portion 7 is fitted to the inner periphery of the brace member 1 by a screw portion 9 formed on the outer periphery of the rear portion, and both are relatively movable in the axial direction. A member 10 screwed to the outer periphery of the shaft portion 7 at the front end of the brace member 1 is a clasp. The hammer-type joint member 3 is fixed to a predetermined position with respect to the brace member 1 by fixing the metal fitting 10 to the shaft portion 7 with a set screw 25.

  The spherical member 4 is composed of two divided spherical members 4a and 4a which are divided into two by a plane including the diameter. Each divided spherical member 4a is provided with a fitting hole 11 that opens to the divided surface and the outer peripheral spherical surface, and a fitting groove 12 is provided on the divided surface. Each divided spherical member 4 a is fitted through the fitting hole 11 and the fitting groove 12 so as to wrap the tip of the shaft portion 7 including the hammer portion 8. Both end surfaces of the hammer portion 8 are formed as convex spherical surfaces that coincide with the outer peripheral spherical surface of the spherical member 4.

  A gap is formed between the inner peripheral surface of the fitting groove 12 and the shaft portion 7 in a state where the spherical member 4 is fitted to the tip of the shaft portion 7. Thereby, the hammer-type joint member 3 is rotatable with respect to the spherical member 4 within a predetermined angle range around the axis of the hammer portion 8.

  The spherical seat 5 is a cylindrical member, and a concave spherical surface 13 for receiving the spherical member 4 is formed at the end. The spherical seat 5 is fitted in a fitting hole 14 formed in the corner fitting 2 and fixed by a hexagon socket head bolt 15.
