(1) JP-A-2000-120778 and JP-A-2000-
Conventional techniques described in JP-A-110400, JP-A-2000-110399, and JP-A-10-299284 are known.

[0003] These are all related to a damper damping device, in which an elastic body is interposed and fixed between flat bar-shaped plates with an adhesive, and a pair of flat plates having the elastic body interposed therebetween is used as a structure. It is used in connection with the skeleton.

[0004] Japanese Patent Laid-Open No. 2000-1 in the prior art described above.
More specifically, taking the example of Japanese Patent Publication No. 20778 as an example, as shown in FIG. 11, an elastic sheet B is fixed to each of the inner surfaces at the distal ends of two first flat bar-shaped plates A, and A second flat bar-shaped plate C is fixedly interposed between the inner side surfaces B1 and B1 of the elastic sheet B to constitute a damper damping device.

A method of fixing the elastic sheet B to the first flat plate-shaped plate A and the second flat plate-shaped plate C is described in page 3, paragraph [0015] of the publication. It is proposed that the adhesive be adhered to the elastic sheet B by using a viscoelastic body and self-adhesive without the use of an adhesive by utilizing the surface adhesive force of the viscoelastic body itself. Have been.

(2) In addition to the damper damping device using such an elastic body, for example, Japanese Patent No. 254107
As disclosed in Japanese Patent Publication No. 3 (1993), hydraulic chambers are formed on both sides of a piston movably provided in a cylinder body, and a pressure regulating valve and a relief valve are provided in a flow path connecting the two hydraulic chambers, 2. Description of the Related Art There is known a damper damping device as an oil damper capable of adjusting a damping characteristic by controlling a set value of an opening / closing operation pressure by hydraulic pressure of these valves.

[0007]

However, the above (1)
Although the damper damping device of (1) has an advantage that the structure is simpler and the size can be easily reduced as compared with the damper damping device of (2), any of the damper damping devices of (1) and (2) However, since mounting accuracy is required, there is a problem that it is difficult for a person who is unfamiliar with the mounting operation to perform accurate mounting.

In other words, when the damper damping device of (1) shown in FIG. 11 is mounted at a position facing the structural frame, the damper damping device is formed on the rear end side of the first flat bar-shaped plates A, A. Mounting holes A2, A2, A2,
A2 'and the holes A1 with the mounting holes C1 and C1 of the fastening member formed on the rear end side of the second flat plate C.
2, A2, A2, A2, C1, and C1 are attached to the opposing positions of a structural frame such as a general house to be reinforced as described above by connecting them with fastening members such as bolts.

Therefore, if the mounting holes A2, A2 of one flat plate are fixed to one of the opposing positions of the structural frame to be mounted, the mounting position of the other hole C1 is unambiguously determined. If the mounting positions of the mounting holes A2, A2 or C1 to be fixed first are not carefully noted, the mounting holes A2, A2
There is a possibility that the alignment between 2 or C1 and a mounting hole (not shown) of the structure skeleton of the other party may not be performed well, and a problem that mounting may fail may occur.

It is considered that one of the causes of such a problem is that the elastic sheet B is bonded and fixed to both the first flat plate-shaped plate A and the second flat plate C in advance. The inventor paid attention. That is, as shown in FIG. 11, the positional relationship between the first and second flat plate-like plates A and C in the X direction and the Y direction cannot be changed at all by fixing with an adhesive. This limits the degree of freedom when attaching to the structural frame.

That is, a first object of the present invention is to provide a damper device which can be easily attached and has a simple structure with a small number of parts by not adhering the elastic body B.

A second object of the present invention is to provide a damper device using an elastic body that also takes into account a reduction in vibration damping force predicted by not using an adhesive.

[0013]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a damper using an elastic body in which a pair of plate-shaped plates are joined and arranged at opposing positions of a structural frame. In the apparatus, the elastic body interposed between the two plate-shaped plates may be configured by pressing and fixing the elastic body between the two plate-shaped plates by pressing and fixing means without bonding using an adhesive or the like. I have to.

Therefore, the two plate-shaped plates obtain a vibration-damping effect by the frictional force between the elastic body and the plate-shaped plate due to the pressing force of the pressing and fixing means, and the mutual position of the plate-shaped plates due to disturbance factors. It is possible to provide a damper device using an elastic body that absorbs even if displacement occurs due to an instantaneous large stress and that can be easily assembled to a structural framework.

More specifically, the invention having the following configuration is provided.

(1) There is a first plate-like plate that can be joined to one of the opposing positions of the structural frame, and a second plate-like plate that can be joined to the other of the opposing positions. 1
A damper device using an elastic body formed by connecting the plate-shaped plate and the second plate-shaped plate by a frictional force with an elastic body, wherein the first plate-shaped plate and the second plate-shaped The elastic body that connects the plates by its frictional force,

In the present invention, without the intervention of an adhesive,
Since the elastic body is configured to connect the first and second plate-shaped plates only by the frictional force of the elastic body,
When attaching the first and second plate-shaped plates to the structural frame, even if the problem of displacement in the X direction or the Y direction as described in the above “Problems to be Solved by the Invention” occurs. Since the elastic body is merely held by the pressing force of the pressing and fixing means, if an excessive force is applied, the first and second plate-like plates may be moved in the X or Y direction (including the θ direction). As a result, it is possible to adjust the relative position of the tumbler device.

(2) The pressing and fixing means is capable of adjusting the pressing and fixing force of the elastic body on the first plate-shaped plate and the second plate-shaped plate by the pressing and fixing means. A damper device using the elastic body according to the above (1).

In the present invention, since the pressing and fixing force of the elastic body can be adjusted by the pressing and fixing means, as described above, when the first and second plate-like plates are attached to the structural frame, When the problem of displacement in the X direction, the Y direction, or the θ direction occurs, the pressing and fixing force of the pressing and fixing means is loosened so that the relative position between the first and second plate-like plates can be easily attached. After adjusting the position,
The mounting can be easily performed by increasing the pressing and fixing force. As the pressing and fixing means capable of adjusting the pressing force, a fastening means such as a bolt and a nut may be employed, but not limited thereto, a similar pressing force can be obtained, and the pressing force can be reduced. Any suitable pressing and fixing means can be adopted as appropriate.

(3) Each of the first plate-shaped plate and the second plate-shaped plate is made of a long rod-shaped rigid plate, and one end of the first plate-shaped plate in the long side direction. The elastic body is disposed so as to be in surface contact with a side of the second plate-shaped plate and one end of the second plate-shaped plate in the long side direction, while the length of the first plate-shaped plate and the second plate-shaped plate is increased. At the other end in the side direction, a joining hole for joining to the structure skeleton is formed, and the pressing and fixing means are disposed in parallel and opposed to each other and a through hole is formed at an outer peripheral end thereof. The pair of third plate-shaped plates formed, and the first plate-shaped plate, the second plate-shaped plate, and the elastic body located between the third plate-shaped plates are paired with the third plate-shaped plate. And a fastening member for pinching and fixing with a plate-shaped plate of A damper device using the elastic body according to the above (1) or (2).

According to the present invention, in a state where the first and second plate-shaped plates are joined to the opposing positions of the structural frame, tensile or compressive stress in the long side direction of the first and second plate-like plates is absorbed by the elastic body. Thus, it is possible to exhibit a vibration damping action.

(4) The first plate-like plate, the elastic body, and the second plate-like plate are each provided with the first plate-like plate.
A through-hole penetrating coaxially in a state where the plate-shaped plate, the elastic body, and the second plate-shaped plate are laminated, and a shaft as the pressing and fixing means is rotatably fitted into the through-hole. The elastic member according to the above (1) or (2), wherein the elastic body is inserted between the first plate-shaped plate and the second plate-shaped plate and pressed and fixed by the shaft portion. Damper device using body.

According to the present invention, vibration suppression in the rotational (θ) direction about the through hole can be suppressed by the frictional force between the elastic body and the plate-like plate.

(5) A groove is formed in at least a part of a pressing surface of the plate-like plate on which the elastic body is pressed, in a direction orthogonal to a direction in which the elastic body is to be joined to the structural frame and reinforced. A damper device using the elastic body according to any one of the above (1) to (4).

According to the present invention, at least a part of the pressing surfaces of the first and second plate-like plates is orthogonal to the direction in which the plate-like plate is to be joined to the structural frame and reinforced. Since the groove is formed in the direction in which the groove is formed, stress is applied more than necessary due to disturbance factors such as earthquakes and winds in the direction to be joined and reinforced with the structural frame, and the pressing force and the elastic body by the pressing and fixing means are applied. As a result, it is possible to reduce the possibility that the first and second plate-like plates are separated from each other by exceeding the frictional force by the above-described method, thereby improving the reinforcing force of the structural frame.

(6) A pressing surface for pressing the elastic body with the first plate-shaped plate or the second plate-shaped plate and the third plate-shaped plate formed of the long rod-shaped rigid plate. The elastic body according to (3), wherein a groove is formed in at least a part of the first plate-shaped plate and the second plate-shaped plate at a position orthogonal to a long side direction of the plate. Damper device using

The reason that the groove is formed in a direction perpendicular to the direction in which the elastic body is to be joined to the structural frame and to be reinforced is that the elastic body is formed by a pair of elastic members as will be described later with reference to the drawings. A first plate-shaped plate is interposed between the second plate-shaped plates, and the elastic body is disposed between the first plate-shaped plate and the second plate-shaped plate, and the pressing is performed by the pressing and fixing means. By pressure, the first and second plate-like plates are joined, and an elastic body is cut into the groove so as to be joined to the structure skeleton to improve a holding force in a direction to be reinforced. For this reason, if the above-described effect of improving the holding force by biting can be obtained, it is not necessary to form the groove in the “perpendicular direction”, and it is sufficient that a vertical component exists.

(7) The first plate pressing the elastic body with the first plate plate and the second plate plate.
(4) wherein at least a part of the pressing surfaces of the plate-shaped plate and the second plate-shaped plate are formed with a plurality of grooves radially about the through hole.
A damper device using the elastic body according to 1.

According to the present invention, the frictional force between the elastic body for fixing the first and second plate-like plates and the plate-like plate is improved by the action of the above-mentioned groove, so that the plate-like plate and the plate-like plate can be used together. By making the elastic body non-adhered, it is possible to suppress a decrease in the vibration damping force in the long side direction, which may be a new problem.

According to the present invention, the vibration damping force in the θ direction centering on the through hole is obtained by the same effect as the invention of the above (7) can be expected to improve the vibration damping effect in the tension or compression direction. Can be improved by the action of the groove.

The first, second and third plate-like plates are preferably formed of a rigid plate made of metal or synthetic resin such as reinforced plastic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings, with reference to the drawings, to a damper device using an elastic body having a vibration damping function to which the present invention is applied. However, the present invention is not limited to this.

Although not specifically described in the following description, the damper device described in each of the embodiments is, for example, a joint between an upper end of a column and a beam and a lower end of a column constituting a building frame. A member that can be used by being joined to one end of a brace as a reinforcing member H that is installed obliquely between the base and the joint of the base, or that is used by joining to a gusset plate H provided at both joints. It is possible.
Of course, a damper device that can be used by directly joining to the building frame H may be used.

(First Embodiment) FIGS. 1 to 4 show a first embodiment of a damper device to which the present invention is applied. FIG. 1 is a plan view of the damper device, and FIG. FIG. 3 is a front view of the damper device, FIG. 3 is a right side view of the damper device, and FIG. 4 is a partially enlarged view showing a portion P in FIG. The left side view of the damper device appears symmetrically with the right side view shown in FIG.

In the drawings, reference numeral 1 denotes a damper device according to the first embodiment, and the damper device 1 is a first damper device which can be joined to one of the opposing positions of the structural frame as described above.
And a second plate-like plate 3 that can be joined to the other of the opposing positions, and one end of the first plate-like plate 2 and the second plate-like plate 3 Surface 2
A, 3A and back surfaces 2B, 3B
Are arranged so as to make surface contact without interposing an adhesive.

The elastic body 5 is provided with pressing and fixing means 6.
The first plate 2 and the second plate 3
Are pressed against the front surfaces 2A, 3A and the back surfaces 2B, 3B of the first and second plates 2 and 3 by the frictional force.

More specifically, each of the first and second plate-like plates 2 and 3 is made of a long rod-shaped rigid plate material, and the first plate-like plate 2 has a long side direction X. The elastic body 5 is disposed so as to make surface contact with one end side of the second plate-shaped plate 3 and one end side in the long side direction X of the second plate-shaped plate 3.
The other end of the second plate-shaped plates 2 and 3 in the long side direction X is provided with a joint hole 2 for joining to the structural frame.
C and 3C are formed.

The pressing and fixing means 6 are disposed in parallel with each other at intervals and have a pair of third plate-like plates 6B, which are rectangular in plan view and have through holes 6A,. 6B and the through holes 6 of the third plate-shaped plates 6B, 6B opposed to each other in parallel with each other.
A and 6A, which are bolts and nuts as fastening means 6C that can be tightened in the direction to narrow the gap. From the pair of side end portions of the third plate-shaped plates 6, 6 where the through holes 6A are not formed, the one end sides of the first and second plate-shaped plates 2, 3 are respectively While being inserted between the third plate-shaped plates 6 and 6 so as to have a certain gap L so as not to overlap with each other, the third plate-shaped plates 6 and 6 are sandwiched and fixed by the fastening force of the fastening means 6C via the elastic body 5. The stronger the tightening force of the fastening means 6C, the greater the resistance in the direction X to pull out the first and second plate-like plates 2, 3 inserted between the third plate-like plates 6, 6. Elastic body 5
It goes without saying that the frictional force between the plate and the plate-like plates 2, 3, 6 increases. The damper device 1 absorbs the vibration in the X direction affected by the disturbance acting on the structural framework by damping the frictional force against the pulling-out force, thereby damping the vibration.

Further, as described above, the elastic body 5 and the plate-like plates 2, 3, and 6 are formed in a non-adhesive structure without using an adhesive. In a state where the plate-shaped plates 2, 3, and 6 are stacked and fastened and fixed in the thickness direction of the layer, the degree of freedom of attachment to the structural skeleton is improved, but the damping force is further increased. For this reason, in this embodiment, the surfaces 2A, 3 of the plate-shaped plates 2, 3 that come into surface contact with the elastic body 5
A and the back surfaces 2B and 3B, and the back surface of the plate-like plate 6,
A plurality of grooves 2D, 3D, 6D are formed in a direction orthogonal to the X direction. Of course, even if the grooves 2D, 3D, and 6D are not formed, the damping device as a damping device for vibration damping is provided by the frictional force between the elastic body 5 and the plate-shaped plates 2, 3, and 6 due to the clamping force of the pressing and fixing means. Since the effect can be obtained, the grooves 2D, 3D, and 6D are not essential components.

The reason why the holding force of the first and second plate-shaped plates 2 and 3 in the X direction is improved by the action of the grooves 3D and 6D will be described with reference to FIG.

That is, when the grooves 2D, 3D, 6D are not provided in the plates 2, 3, 6B, the holding force of the first and second plate-like plates 2, 3 in the X direction is limited by the pressing force. In the case where the grooves 2D, 3D, and 6D are provided, it depends only on the frictional force between the plate-shaped plates 2, 3, and 6B and the elastic body 5 according to the tightening force of the fixing means 6 by the fastening means 6C.
The elastic body 5 is deformed and bites into the grooves 2D, 3D, 6D according to the tightening force of the pressing means 6 by the fastening means 6C. The biting due to the deformation of the elastic body 5 improves the holding force of the first and second plate-like plates 2 and 3 in the X direction.

(Second Embodiment) Next, referring to FIGS. 5 and 6, a second embodiment which is a modification of the above-described first embodiment will be described.
An embodiment will be described. The damper device 1 according to the second embodiment employs a structure in which the second plate-shaped plate 3 is integrally formed so as to also play the role of the above-described third plate-shaped plate 6B. Are similar.
