Description

  The present invention belongs to the technical field of vibration control studs installed between upper and lower beams in a pillar / beam frame of a building structure, and more specifically, viscoelastic dampers or lead dampers control small amplitudes such as wind fluctuations. The present invention relates to a damping stud that exhibits a vibration function, with steel dampers exhibiting a damping function for medium and large amplitudes during an earthquake, and exhibiting a damping function in a wide amplitude range.

  Conventionally, a vibration damping device that employs a steel material damper such as a low yield point steel is known, and variously devised. For example,

(I) The vibration damping devices of Patent Documents 1 and 2 are configured such that a small-amplitude damper is connected in series to a steel damper, and a medium-large amplitude region in which the steel damper exhibits a damping function well. In addition, it has been devised so that it can exhibit a good damping function even in a small amplitude region such as wind fluctuation.

(Ii) The vibration damping devices of Patent Documents 3 and 4 are configured such that a vertical load is not transmitted to the steel damper, and are devised so as to prevent the vibration damping function from being lowered.

(Iii) The vibration damping devices of Patent Documents 5 and 6 are configured to follow horizontal deformation in the out-of-plane direction, and are devised to prevent damage to the vibration damping device.

  Although the vibration damping devices of Patent Documents 1 to 6 solve individual problems, they cannot satisfy all the problems at the same time.

Therefore, the present applicant has developed a vibration damping device that can solve all the above problems and has filed a patent application.
(Iv) The vibration damping device of Patent Document 7 includes a steel material damper, a wall-type viscous material damper, and an out-of-plane deformation follow-up member. A predetermined clearance is provided between the resistance plate immersed in the viscous body in the viscous body container and the viscous body container, and the resistance plate is within the clearance for small amplitudes such as wind fluctuations. By moving, the viscous damper exhibits a damping function. On the other hand, with respect to a large amplitude during an earthquake, the resistance plate collides with the viscous material container and transmits a horizontal force to the steel material damper, and the steel material damper exhibits a damping function. And the steel material damper is made into the shape curved in the in-plane direction in the shape of a letter, and is set as the structure which absorbs a vertical load and prevents the damping function from falling. Further, the horizontal deformation in the out-of-plane direction can be followed by the action of the out-of-plane deformation following member.

  Embodiments of the vibration damping stud according to the invention described in claim 1 and claims 4 and 6 will be described with reference to FIGS.

  The vibration control pillar 1 is installed between the upper and lower beams 4 and 4 in the frame 5 formed by the pillar 3 and the beam 4 of the building structure 2 in substantially the same manner as a conventional vibration control pillar. A steel damper 8 is a viscoelastic damper 9 between a rigid upper column member 6 suspended from 4 and a rigid lower column member 7 raised from the lower beam 4 so as to face the upper column member 6. It is set as the structure installed via (refer FIG.1 and FIG.2).

It is reinforced to prevent bending (see FIGS. 2 and 3).

  The viscoelastic damper 9 has a configuration in which a viscoelastic body 15 of a usual silicon type (however, the material is not limited) is installed between the connecting member 13 on the stud member side and the connecting member 14 on the steel material damper side. Has been. Specifically, the connecting member 13 on the stud member side is made of a steel plate, and the surface 13a on the steel material damper side is an convex convex lens-shaped R convex surface (hereinafter referred to as the surface on the steel material damper side). 13a is used). The connecting member 14 on the steel material damper side is also made of a steel plate, and the surface 14a on the stud member side is concave lens-shaped R toward the out-of-plane direction so as to correspond to the convex lens-shaped R convex surface 13a of the connecting member 13. It is formed in a concave surface (hereinafter, the same reference numeral 14a as the surface on the side of the stud member is used) (see FIG. 3B). Between the R-convex surface 13a and the R-concave surface 14a, which are relatively bent, exhibit a good damping function when deformed, and absorb vertical loads originating from the creep phenomenon of the building structure 2 and the like. The viscoelastic body 15 having a sufficient thickness is installed, and is configured as a pin mechanism that can be rotated by deformation of the viscoelastic body 15 (see FIGS. 2 and 3, inventions according to claims 4 and 6). ).

  Viscoelastic dampers 9 and 9 are respectively disposed at the upper and lower ends of the steel damper 8, and the upper and lower sides of the steel frame 11 of the steel damper 8 and the connecting member 14 of the viscoelastic damper 9 are connected and integrated. ing.

  The vibration damping stud 1 having the above configuration exhibits a good vibration damping function in a wide amplitude region from a small amplitude such as wind shaking to a middle / large amplitude during an earthquake. In addition, since the viscoelastic damper 9 exhibits an out-of-plane tracking function, a vibration control function against small amplitudes such as wind fluctuations, and a vertical load absorbing function, the number of members is small and the structure is simple. Therefore, workability is good and can contribute to cost reduction.

  The damping pillar 1 of the first embodiment is configured to have viscoelastic dampers 9 and 9 at the upper and lower ends of the steel damper 8 but only one end is shown in FIGS. 7 and 8. The configuration of the above can be implemented in substantially the same manner.

In this case, as shown in FIG. 11, the male part 18a may be fitted with a female part 19a having a side view formed in a keyhole shape and a side view formed in a C-shape (the invention according to claim 8).

And the viscoelastic body 15 is installed between the inner peripheral surface of the cylindrical part 21a and the outer peripheral surface of the rotating shaft 22 (invention of Claim 9).

  Although the viscoelastic dampers 9 (17, 20) of the first to third embodiments are configured to directly collide with the stopper member 16, the viscoelasticity is used as a buffer material between the stopper member 16 and the stopper member 16 as illustrated in FIG. If the body 23 is installed, it will not be damaged when it collides (invention of claim 10).

Although the said Examples 1-4 are implemented using the viscoelastic damper 9 (17, 20), even if it uses a lead damper, it can implement substantially similarly (illustration is abbreviate | omitted).
That is, the steel damper 8 is vertically moved through a lead damper having a structure in which lead is installed instead of the viscoelastic body 15 of the viscoelastic damper 9 (17, 20) of the first to fourth embodiments. It is installed between the stud members 6 and 7 (Invention of Claim 1 and Claims 5-9).
In this case as well, it is advantageous to install lead as a buffer material between the lead damper and the stopper member 16 in substantially the same manner as in the fourth embodiment (the invention according to claim 10).

In the damping damping column 24 of the present embodiment, wall type viscoelastic dampers 25 are provided at both upper and lower ends of the steel damper 8 (see FIG. 14).
The wall-type viscoelastic damper 25 includes a viscoelastic body container 29 in which a resistance plate 27 formed on the upper connection member 26 has an inner circumference that is slightly larger than the outer periphery of the resistance plate 27 formed on the lower connection member 28. The viscoelastic body 15 is installed between the outer peripheral surface of the resistance plate 27 and the inner peripheral surface of the viscoelastic container 29 (the invention according to claim 2).

  With respect to horizontal deformation in the out-of-plane direction, the viscoelastic body 15 installed between the resistance plate 27 and the viscoelastic body container 29 is deformed, so that the damping pillar 24 can follow the out-of-plane direction. It has a structure and exhibits a vibration control function.

  For horizontal deformation in the in-plane direction, when a small amplitude is generated due to wind fluctuation or the like, the viscoelastic body 15 installed between the resistance plate 27 and the viscoelastic body container 29 is deformed to have a damping function. Demonstrate. On the other hand, when a medium or large amplitude occurs due to an earthquake, the resistance plate 27 strongly pushes the viscoelastic body container 29 via the viscoelastic body 15 and transmits a horizontal force to the steel damper 8. And the steel material damper 8 to which the horizontal force was transmitted deform | transforms and yields, and exhibits a damping function. That is, the distance L between the resistance plate 27 and the viscoelastic body container 29 in the in-plane direction is such that almost all horizontal force is applied to the steel damper 8 when a medium or large amplitude exceeding a small amplitude such as wind fluctuation occurs. It is supposed to be transmitted.

  A vertical load originating from a creep phenomenon or the like is absorbed by contracting the viscoelastic body 15 disposed between the lower surface of the resistance plate 27 and the bottom surface of the viscoelastic body container 29.

  The vibration damping pillars 24 of the sixth embodiment are configured to have wall-type viscoelastic dampers 25 and 25 at the upper and lower ends of the steel damper 8, but may be configured only at the lower ends as shown in FIG. 15. Although not shown, a configuration having only the upper end may be used. Moreover, as shown in FIG. 16, even if the wall-type viscoelastic damper 25 is upside down, it can be implemented in substantially the same manner.

Although the above Example 6 was implemented using the wall type viscoelastic damper 25, it can be implemented in substantially the same manner using a wall type lead damper.
That is, in the damping damping column 30 of FIG. 17, the steel damper 8 is installed between the upper and lower beams 4 and 4 via the wall-type lead damper 31. The wall-type lead damper 31 has substantially the same configuration as the wall-type viscoelastic damper 25 of the sixth embodiment, and a lead container in which a resistance plate 27 formed on the upper connecting member 26 is formed on the lower connecting member 28. The lead 33 is inserted between the surface parallel to the in-plane direction of the resistor plate 27 and the inner peripheral surface of the lead container 32, and the surface parallel to the out-of-plane direction of the resistor plate 27 and lead. A predetermined clearance T < _b > ₂ is opened between the inner peripheral surface of the container 32. The predetermined clearance T ₂ referred here, when a large amplitude and in more than small amplitude such as wind shaking occurs, the resistance plate 27 is sized to impinge on the bomb 32 (according to claim 3, wherein invention).
