The lower transmission member 16 includes a structural plate 16A, a left batten bracket 16B, a right batten bracket 16C, and a damper bracket 16D. The lower transmission member 16 vibrates horizontally (horizontally) together with the lower beam 3 through the left batten 12 , right batten 13 , left pillar 4 and right pillar 5 . A piston rod 17B of the damper 17 is attached to the damper bracket 16D.

A damper 17 is provided between the upper transmission member 15 and the lower transmission member 16 . The damper 17 damps relative displacement due to vibration between the upper transmission member 15 and the lower transmission member 16 . The damper 17 includes a cylinder 17A filled with hydraulic oil and a piston rod 17B that is coupled to a piston (not shown) that slides within the cylinder 17A and protrudes from the cylinder 17A.

The damper 17 is arranged to extend in the horizontal direction (left-right direction), one end of the cylinder 17A is rotatably attached to the damper bracket 15D of the upper transmission member 15, and the other end of the piston rod 17B is It is attached to the damper bracket 16D of the transmission member 16 so as to be rotatable. As a result, the damper 17 attenuates relative displacement due to vibration between the upper transmission member 15 and the lower transmission member 16 by means of a damping valve (not shown) provided on the piston. In addition, the damper 17 is good also as a structure which provides two or more.

Two sets of upper anti-vibration members 18 are provided between the left brace 12 and the right brace 13 with an interval in the vertical direction. The two sets of upper anti-vibration members 18 suppress vibration in a direction (thickness direction of the structural plate 15A) different from the direction in which the upper transmission member 15 is relatively displaced (horizontal direction). As shown in FIGS. 5, 7 and 8, the upper anti-vibration member 18 is positioned between the wall plate 6 and the structural plate 15A of the upper transmission member 15 and extends in the left-right direction. 19 and a front side guide 20 provided to face the back side guide 19 with the structural plate 15A interposed therebetween.

The far side guide 19 has, for example, its ends attached to the facing surfaces 12C and 13C of the battens 12 and 13, respectively. The rear-side guide 19 abuts on the structural plate 15A that is about to move toward the wall plate 6, thereby suppressing the swinging of the structural plate 15A toward the wall plate 6. As shown in FIG.

Two sets of front side guides 20 are provided at positions facing the surface (front surface) of the structural plate 15A, extending in the left-right direction. At both ends of the front guide 20, screw insertion holes 20A are formed at positions corresponding to the screw holes 12E positioned above the battens 12 and 13. As shown in FIG. Further, screw holes 20B are formed on both sides of the surface of the front side guide 20 for fixing the upper box furniture 24, which will be described later.

The front side guide 20 is arranged so as to be placed on the surface of the structural plate 15A, and the screw members 14 inserted through the screw insertion holes 20A are screwed into the screw holes 12E and 13E of the battens 12 and 13, respectively. As a result, the front guide 20 abuts on the structural plate 15A that is about to move to the side opposite to the wall plate 6, thereby suppressing the swinging of the structural plate 15A to the side opposite to the wall plate 6.例文帳に追加

Therefore, the upper anti-vibration member 18 has a configuration in which the structural plate 15A is sandwiched between the back side guide 19 and the front side guide 20 in the thickness direction. With this configuration, the upper anti-vibration member 18 can guide the upper transmission member 15 so that it does not swing in a direction different from the direction in which it is relatively displaced. Thereby, the displacement due to vibration can be efficiently (directly) acted on the damper 17 . In addition, the upper anti-vibration member 18 can also be arranged such that the rear side guide 19 and the front side guide 20 are shifted in the vertical direction.

Similar to the upper anti-vibration member 18, the lower anti-vibration member 21 suppresses vibration in a direction (thickness direction of the structural plate 16A) different from the direction in which the lower transmission member 16 is relatively displaced (horizontal direction). The two sets of lower anti-vibration members 21 are composed of a back side guide 22 and a front side guide 23 (screw insertion hole 23A, screw hole 23B). With this configuration, the lower anti-vibration member 21 can guide the lower transmission member 16 so as not to swing in a direction different from the direction in which the lower transmission member 16 is relatively displaced.

Thereby, the upper box furniture 24 is fixed at a position covering the upper transmission member 15 . At this time, each screw insertion hole 24C formed as an elongated hole extending in the left-right direction can allow displacement of the upper transmission member 15, and can prevent deformation of the upper box furniture 24.

The lower box furniture 25 is obtained by vertically inverting the upper box furniture 24 at the position of the damper 17 , and constitutes a cover member that covers the lower transmission member 16 . The lower box furniture 25 has a frame plate 25A, a back plate 25B, and screw insertion holes 25C.

Here, a space is formed between the upper box furniture 24 and the lower box furniture 25, and the damper 17 can be seen through this space. In this case, the damper 17 can be used as part of the interior.

Next, an example of a work procedure for attaching the vibration damping device 11 to the structure 1 after construction will be described.

First, as a preparatory work for attaching the vibration damping device 11 to the structure 1 after construction, the left pillar 4 and the right pillar 5 are searched on the back side (back) of the wall plate 6 using design drawings and inspection equipment.

Subsequently, the batting brackets 15B, 15C of the upper transmission member 15 are fixed to the facing surfaces 12C, 13C of the battings 12, 13 using screw members. A structural plate 15A is attached to each of the batting brackets 15B and 15C, and a damper bracket 15D is attached to the structural plate 15A. Similarly, the batting brackets 16B, 16C of the lower transmission member 16 are fixed to the facing surfaces 12C, 13C of the battings 12, 13 using screw members. A structural plate 16A is attached to each batting bracket 16B, 16C, and a damper bracket 16D is attached to the structural plate 16A. Furthermore, between the damper bracket 15D of the upper transmission member 15 and the damper bracket 16D of the lower transmission member 16, a damper 17 is attached so as to extend in the horizontal direction.

Next, as shown in FIG. 7, the front side guide 20 of each upper anti-vibration member 18 is arranged so as to cover the surface of the structural plate 15A, and the screw member 14 inserted through each screw insertion hole 20A is attached to each contact. It is screwed into screw holes 12E and 13E of trees 12 and 13. As a result, each of the front guides 20 abuts against the structural plate 15</b>A that is about to move to the side opposite to the wall plate 6 , thereby suppressing the swinging of the upper transmission member 15 to the side opposite to the wall plate 6 .

By the work so far, as shown in FIGS. 4 and 6, the vibration damping device 11 has a structure for absorbing the vibration of the structure 1 .

Next, after installing each anti-vibration member 18, 21, the back plate 24B of the upper box furniture 24 is arranged so as to be attached to the front side guide 20 of each upper anti-vibration member 18, and each screw insertion hole of the back plate 24B The threaded member 26 inserted through 24C is screwed into the threaded hole 20B of each front side guide 20.

At this time, the left batten 12 and the right batten 13 are also displaced together with the left pillar 4 and the right pillar 5.例文帳に追加Displacements of the left brace 12 and the right brace 13 are input to the damper 17 through the upper transmission member 15 and the lower transmission member 16 . As a result, the damper 17 generates a damping force as the piston slides in the cylinder 17A, absorbs the vibrational energy acting on the structure 1, and suppresses the vibration.
