Description

  The present invention relates to a vibration control structure that reduces and reduces the vibration of a building when a large external force such as an earthquake or a strong wind is applied to the building, and in particular, surrounds a column and a beam. The present invention relates to a vibration control structure disposed in a wall space.

  Conventionally, in buildings, condominiums and other buildings, when a large external force such as an earthquake or strong wind is applied, the external force is reduced to reduce and attenuate the vibration of the building. There is known a vibration damping structure in which a vibration damping device is disposed in an enclosed wall space.

  For example, as shown in FIG. 7, both upper ends of the V-shaped support member 106 are fixed to both ends of the upper beam 104, and the lower ends thereof are positioned in the vicinity of the middle portion of the lower beam 105. A shear link type vibration damping structure 101 in which an oil damper 107 is installed between the lower end of the support member 106 and the lower end of the support member 106 is well known (see Patent Document 1).

In this shear link type vibration control structure 101, when a large external force such as an earthquake or a strong wind is applied, the left and right columns 102 and 103 swing in the horizontal direction as shown in FIG. A horizontal displacement δ occurs between the lower beam 104 and the lower beam 105 (interlayer deformation).
The rod of the oil damper 107 extends by the amount of the deviation δ. At this time, the external force is reduced and the vibration is attenuated by the resistance by the oil.

  As another form, as shown in FIG. 9 (A), a brace 206 (a brace) is bridged between the right end portion of the upper beam 204 and the left end portion of the lower beam 205, and an oil damper is provided at an intermediate portion of the brace 206. Bracing L-shaped damping structure 201 (see Patent Document 2) provided with 207, as shown in FIG. 9 (B), on the left end portion of the upper beam 304 and the middle portion of the lower beam 305, and on the upper beam Bracing 306, 307 (bar crossing) is bridged between the right end of 304 and the middle of lower beam 305, and oil dampers 308, 309 are installed in the middle of these braces 306, 307. Is also known.

  Also in these vibration control structures, a large external force is applied, the left and right columns 202, 203 (302, 303) swing in the horizontal direction, and the upper beam 204 (304) and the lower beam 205 (305) move in the horizontal direction. When the displacement occurs, the rod of the oil damper 207 (308, 309) extends or contracts to reduce the external force and attenuate the vibration.

  Further, as shown in FIG. 10 (A), a stud column type in which studs 406 and 407 are disposed between the upper and lower beams 404 and 405 and a steel plate member 408 is installed in the middle of the studs 406 and 407. As shown in FIG. 10 (B), a wall-type damping structure 501 in which a plate member 506 made of steel is installed between upper and lower beams 504 and 505 is also known.

  In these vibration control structures, a large external force is applied, the left and right columns 402 and 403 (502 and 503) swing in the horizontal direction, and the upper beam 404 (504) and the lower beam 405 (505) move in the horizontal direction. When the deviation occurs, the steel plate-like member 408 (506) undergoes shear deformation, and the shear stress reduces external force and attenuates vibration.

  However, in the conventional damping structure, the amount of extension or contraction of the rod of the oil damper is small compared to the amount of horizontal displacement between the upper beam and the lower beam, and The amount of shear deformation of the plate-like member is small, the external force is reduced, the vibration is damped, and the vibration damping effect is not sufficient.

The present invention has been made in view of such conventional problems, and the amount of extension of the rod of the oil damper is larger than the amount of horizontal displacement between the upper beam and the lower beam. An object of the present invention is to provide a vibration damping structure that is sufficiently large and thus reduces external force, damps vibrations, and greatly improves the vibration damping effect.

  In order to achieve the above object, the vibration damping structure of the present invention has a vibration damping frame disposed in a wall space surrounded by left and right columns and upper and lower beams, and a highly rigid holding frame is provided on the vibration damping frame. The vibration control frame and the holding frame are rotatably connected to each other via a pivot, and the vibration control frame includes the left and right columns and the upper and lower columns. It is not installed on the same plane as the beam.

Here, the holding frame may be disposed on both sides of the vibration control frame.

The holding frame may be disposed only on one side of the vibration control frame.

The vibration control frame preferably includes a V-shaped support member and an oil damper.

The holding frame is composed of a vertical rod, an upper rod, and a lower rod, and a brace is disposed across the distal end portion of the upper rod and the base end portion of the lower rod. It is preferable to do this.

  Furthermore, it is possible to configure a vibration damping structure in which the vibration damping structure, which is the basic form, is arranged over a plurality of floors using the vibration damping structure as a basic form.

  According to the vibration damping structure of the present invention, the amount of extension of the rod of the oil damper can be made sufficiently larger than the amount of displacement in the horizontal direction between the upper beam and the lower beam. The vibration control effect can be greatly improved by reducing and damping the vibration.

It is arranged in the direction.
The difference between the vibration damping structure of the present invention and the conventional vibration damping structure is that a highly rigid holding frame is disposed on both sides of a vibration damping frame composed of a support member and an oil damper via a pivot.

As shown in FIG. 1, the vibration control frame 10 includes an upper rod 11, a lower rod 12, a V-shaped support member 13, and an oil damper 14.

  The upper collar 11 has connecting pieces 15 and 15 protruding at both ends thereof, and the lower hook 12 also has connecting pieces 16 and 16 protruding at both ends thereof.

  Both upper ends of the support member 13 are fixed to both ends of the upper ridge 11, and lower ends thereof are positioned in the vicinity of an intermediate portion of the lower ridge 32.

  The oil damper 14 is disposed in parallel with the upper and lower flanges 11 and 12, and one end thereof is fixed to the lower end of the support member 13.

  As shown in FIG. 1, the holding frame 20 is composed of a vertical rod 21, an upper rod 22, a lower rod 23, and braces 24.

The upper end of the upper rod 22 is fixed to the upper end of the vertical rod 21, and the lower end of the lower rod 23 is fixed to the lower end of the vertical rod 21.
Further, a connecting piece 25 protrudes from the upper end of the vertical rod 21, and a connecting piece 26 protrudes from the lower end.

  Then, the base end of the upper rod 22 is fixed to the upper end of the left column 2, and the base end of the lower rod 23 is fixed to the lower end of the left column 2.

  Further, one end of a brace (stiffener) 24 is fixed to the connecting portion between the vertical scissors 21 and the upper scissors 22, and the other end of the brace 24 is connected to the pillar 2 and the lower scissors 23. It is fixed to the connecting part.

Since the holding frame 20 is configured as described above, a highly rigid frame is configured by the left column 2, the vertical rod 21, the upper rod 22, and the braces (struts) 24 arranged obliquely. Will be.
Therefore, even when a large external force is applied, the holding frame 20 has a rigid structure that hardly deforms.

  As shown in FIG. 1, the holding frame 30 is composed of a vertical rod 31, an upper rod 32, a lower rod 33, and braces 34.

The upper end of the upper rod 32 is fixed to the upper end of the vertical rod 31, and the lower end of the lower rod 33 is fixed to the lower end of the vertical rod 31.
A connecting piece 35 protrudes from the upper end portion of the vertical rod 31 and a connecting piece 36 protrudes from the lower end portion.

  The base end portion of the upper side rod 32 is fixed to the upper end portion of the right column 3, and the base end portion of the lower side rod 33 is fixed to the lower end portion of the right column 3.

  Further, one end of a brace 34 is fixed to a connecting portion between the vertical rod 31 and the upper rod 32, and the other end of the brace 34 is connected to the column 3 and the lower rod 33. It is fixed to the connecting part.

Since the holding frame 30 is configured as described above, a high-rigidity frame is configured by the right column 3, the vertical rod 31, the upper rod 32, and the braces 34 that are disposed obliquely. Will be.
Therefore, even when a large external force is applied, the holding frame 30 has a rigid structure that hardly deforms.

The connecting pieces 15, 15 projecting from the upper rod 11 and the connecting pieces 25, 35 projecting from the vertical rods 21, 31 are pivotally connected via pivots 41, 41.
Further, the connecting pieces 16 and 16 protruding from the lower rod 12 and the connecting pieces 26 and 36 protruding from the vertical rods 21 and 31 are rotatably connected via pivots 42 and 42.

Furthermore, the vibration damper 10 and the holding frames 20 and 30 on both sides are connected by fixing the other end of the oil damper 14 to an intermediate portion near the lower end of the vertical rod 21.

  As described above, the vibration control frame 10 connects the upper and lower rods 11 and 12 to the upper and lower ends of the vertical rods 21 and 31 via the pivots 41 and 41 and the pivots 42 and 42, respectively. When the upper rod 22 and 32 and the lower rod 23 and 33 are swung, the upper rod 11 and the lower rod 12 are appropriately rotated around the pivots 41 and 41 and the pivots 42 and 42. It is supposed to be.

  On the other hand, the rod of the oil damper 14 expands or contracts as the upper rod 11 and the lower rod 12 are appropriately rotated and the angle between the vertical rod 21 and the upper rod 11 and the lower rod 12 is displaced. It is like that.

  The vibration damping structure 1 of the present invention has the above-described structure. Next, the functions and effects produced by the structure will be described.

  FIG. 2 is an explanatory diagram showing the behavior of each structural member when a large external force is applied and interlayer deformation occurs in the vibration damping structure 1 of the present invention.

  When a large external force such as an earthquake or a strong wind is applied to the vibration damping structure 1 of the present invention, the left and right columns 2 and 3 swing in the horizontal direction as shown in FIG. When a horizontal deviation δ occurs with the lower beam 5, the vertical rods 21 and 31 also swing and displace at a predetermined angle with the vertical direction in response to this.

Further, when the vertical rods 21 and 31 are displaced at a predetermined angle with respect to the vertical direction, the upper rod 11 and the lower rod 12 are rotated by a predetermined angle around the pivots 41 and 41 and the pivots 42 and 42, The quadrangle formed by the vertical rods 21 and 31, the upper rod 11 and the lower rod 12 is deformed,
As shown in FIG. 2B, the shape is transformed from a rectangle to a parallelogram.

  On the other hand, the support member 13 is also displaced in response to the behavior of the upper rod 11, but the lower end of the support member 13 is only fixed to one end of the oil damper 34. Is increased so that the rod of the oil damper 34 is extended.

In the vibration damping structure 1 of the present invention, the vibration damping frame 10 and the holding frames 20 and 30 having high rigidity on both sides are rotatably connected to each other via pivots 41 and 41 and pivots 42 and 42. Since the frame 10 is freely displaced without being directly affected by the behavior of the upper and lower beams 4, 5, the extension amount βδ of the rod of the oil damper 34 becomes extremely large as compared with the conventional vibration damping structure.
Therefore, according to the vibration damping structure 1 of the present invention, the external force can be greatly reduced and the vibration can be greatly attenuated, so that the vibration damping effect can be significantly improved.

As shown in FIG. 2A, in the normal state, the upper ridge 11 (or the lower ridge 12) of the vibration control frame 10, the upper ridge 22 (or the lower ridge 22) of the holding frame 20, and the upper side of the holding frame 30. The total length of the hooks 32 (or lower hooks 32) is L, and the lengths of the upper hooks 22 (or lower hooks 22) of the holding frame 20 and the upper hooks 32 (or lower hooks 32) of the holding frame 30 are set. Let each be a.

Then, a large external force such as an earthquake or a strong wind is applied, and as shown in FIG. 2B, the left and right pillars 2 and 3 swing horizontally, and between the upper beam 4 and the lower beam 5. Assuming that a horizontal displacement δ occurs, the extension amount of the rod of the oil damper 14 becomes βδ.

here,

β = 1 + (2a / L-2a)

Therefore, if the ratio of a to L is appropriately changed and the value of β is calculated,

a / L = 0.05: β = 1.11
a / L = 0.10: β = 1.25
a / L = 0.15: β = 1.43
a / L = 0.20: β = 1.67
a / L = 0.25: β = 2.00

It becomes.

In any case, in the conventional vibration damping structure 101 shown in FIG. 8, when a horizontal displacement δ occurs between the upper beam 104 and the lower beam 105, as shown in FIG. Since the extension amount of the rod of the oil damper 107 is δ, it is understood that the extension amount of the rod of the oil damper 34 is greatly increased to βδ in the vibration damping structure 1 of the present invention.
Therefore, according to the vibration damping structure 1 of the present invention, the external force can be greatly reduced, the vibration can be greatly attenuated, and the vibration damping effect can be greatly improved.

  In the case of this embodiment, the displacement amount per unit of the oil damper 14 can be further increased.

  However, in the case of constituting the vibration damping structure 81, it is necessary to arrange in a space that blows through a plurality of floors, so that it is preferable to use an elevator installation space or the like.

Can also be configured.

  However, when the vibration damping structure 91 is configured, the rigidity and proof strength of the portion constituting the vibration damping structure 91 are greatly reduced. Therefore, the surroundings are surrounded by the pillars 2a and the beams 4a on both sides of the portion constituting the vibration damping structure 91.

As shown in FIG. 11B, the vibration damping frame 610 and the holding frame 620 are provided. It is arranged outside the plane defined by the left and right columns 2 and 3 and the upper and lower beams 4 and 5.

The structures of the vibration control frame 610 and the holding frame 620 are the same as those of the vibration control structure 1 shown in FIG. 1, but the holding frame on one side is omitted, and therefore, the connecting piece 615 protruding from the upper side flange 611 of the vibration control frame 610 and A connecting piece 631 projecting from the column 3 is rotatably connected via a pivot 641.
Further, a connecting piece 616 protruding from the lower shaft 612 of the vibration control frame 610 and a connecting piece 632 protruding from the column 3 are connected via a pivot 642 so as to be rotatable.

  The vibration damping structure 601 of the present invention has the above-described structure, and the operation and effect thereof will be described below.

  FIG. 12 is an explanatory diagram showing the behavior of each structural member when a large external force is applied and interlayer deformation occurs in the vibration damping structure 601 of the present invention.

  When a large external force such as an earthquake or a strong wind is applied to the vibration damping structure 601 of the present invention, the left and right columns 2 and 3 swing in the horizontal direction as shown in FIG. When a horizontal deviation δ occurs between the lower beam 5 and the vertical beam 621, the vertical rod 621 swings and displaces at a predetermined angle with respect to the vertical direction.

Therefore, according to the vibration damping structure 601 of the present invention, the external force can be greatly reduced and the vibration can be greatly attenuated, so that the vibration damping effect can be significantly improved.

As shown in FIG. 12 (A), the total length of the upper ridge 611 (or the lower ridge 612) of the vibration control frame 610 and the upper ridge 622 (or the lower ridge 622) of the holding frame 620 is set as normal. L, the length of the upper ridge 622 (or the lower ridge 622) of the holding frame 620 is a.

Then, when a large external force such as an earthquake or strong wind is applied, the left and right columns 2 and 3 swing in the horizontal direction as shown in FIG. 12 (B), and between the upper beam 4 and the lower beam 5. Assuming that a horizontal displacement δ occurs, the extension amount of the rod of the oil damper 614 is γδ.

γ = 1 + (b / L−b)

Therefore, if the ratio of b to L is appropriately changed and the value of γ is calculated,

b / 2L = 0.05: γ = 1.11.
b / 2L = 0.10: γ = 1.25
b / 2L = 0.15: γ = 1.43
b / 2L = 0.20: γ = 1.67
b / 2L = 0.25: γ = 2.00

It becomes.

In any case, in the conventional vibration damping structure 101 shown in FIG. 8, when a horizontal displacement δ occurs between the upper beam 104 and the lower beam 105, as shown in FIG. Since the extension amount of the rod of the oil damper 107 is δ, it is understood that the extension amount of the rod of the oil damper 614 is greatly increased to γδ in the vibration damping structure 601 of the present invention.
Therefore, according to the vibration damping structure 601 of the present invention, the external force can be greatly reduced, the vibration can be greatly attenuated, and the vibration damping effect can be greatly improved.
