Abstract
Description
[Technical field]
[0001] The present invention relates to a vibration-damping structure, and more particularly to a vibration-damping structure in which earthquake energy absorbing elements are added to studs or mullion walls in the longitudinal or inter-beam direction of an architectural structure. [Background technology]
[0002] A typical structural form for architectural structures is the pure rigid frame structure, which is made up of a framework of columns and beams. Pure rigid frame structures do not have braces or earthquake-resistant walls, and are structured to resist earthquake loads using the bending shear strength of the columns and beams. To ensure habitability, studs, mullioned walls, and floors are installed as appropriate to form rooms or partitions.
[0003] On the other hand, in recent years, in order to provide higher earthquake resistance to the pure rigid frame structure, vibration control structures that add various dampers, which are elements that absorb earthquake energy, have been developed and put into practical use. Specific examples of vibration control structures include the direct joint type (bracing type) and the indirect joint type (stud type).
[0004] The direct joint type (bracing type) adds vibration control to the wall by installing a damper in the middle of the bracing. However, because the direct joint type (bracing type) structure uses bracing to control vibration, it has problems such as blocking the room even in places where walls are not needed to ensure habitability, or making it difficult to install windows, which impedes lighting, making it difficult to popularize this type in new buildings from the standpoint of design and functionality.
[0005] In contrast, the indirect joint type (stud type) is superior in design and functionality because it does not impede lighting. As an example of such an indirect joint type seismic control structure, a seismic control structure using a shear type panel damper made of low yield point steel has been proposed (see Patent Document 1). According to this proposal, by using a shear type panel damper made of yield point steel, the axial force (earthquake energy) caused by an earthquake is smoothly transmitted from the building structure to the shear type panel damper, and the earthquake energy can be sufficiently attenuated by the plastic deformation of the shear type panel damper.

[0006] [Patent Document 1] JP 2019-27195 A Summary of the Invention [Problem to be solved by the invention]
[0007] However, the seismic control structure using shear type panel dampers proposed in the above-mentioned Patent Document 1 uses shear type panel dampers made of steel, so there is still room for improvement in terms of energy absorption performance for repeated earthquake motion and vertical loads. Also, because the shear type panel dampers are embedded and fixed into the partitions, there is room for improvement in terms of retrofitting workability and maintainability after installation.
[0008] The present invention has been made in consideration of the above circumstances, and has as its objective the provision of a seismic control structure which fully retains the functionality of partition posts and upright walls, maintains the interior design and livability, has excellent seismic control properties against repeated earthquake motion, and is easy to install, replace, and maintain after the fact. [Means for solving the problem]

Secondly, in the seismic control structure of the first invention above, brackets are arranged on both ends of the rod, and the brackets are fixed to either the upper or lower end of the upper beam or lower beam, the partition wall or the upper or lower end of the middle part of the partition wall, and it is preferable that a die fixing member is provided on the die, and the die fixing member is fixed to either the lower or upper end of the lower beam or upper beam, the partition wall or the lower or upper end of the middle part of the partition wall. Thirdly, in the vibration damping structure of the first or second invention, it is preferable that a width adjustment member is provided at an end of the rod. Fourthly, in the vibration damping structure of the first to third inventions, it is preferable that the bracket is fixed to an end of the rod. Fifth, in the vibration control structure of the first to fourth inventions, it is preferable that the building is any one of a reinforced concrete building, a steel frame building, and a steel framed reinforced concrete building. Sixth, in the seismic control structure of the fifth invention above, if the building is a steel-framed building, it is preferable that the partitions or mullion walls are made of steel, and if the building is a reinforced concrete building or a steel-reinforced concrete building, it is preferable that the partitions or mullion walls are made of steel, reinforced concrete, or reinforced steel concrete.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] The vibration-damping structure of the present invention will be described in detail below with reference to the drawings, showing the embodiment for carrying out the invention. Figure 1 is a schematic diagram of a vibration-damping structure according to an embodiment in which friction dampers are installed on studs, and Figure 5 is a schematic diagram of a vibration-damping structure according to an embodiment in which friction dampers are installed on mullion walls.
[0014] The vibration control structure 1 of the present invention comprises a friction damper 5 having a rod 51 and a die 52 arranged parallel and horizontally to a wall surface 6 at least at the upper end, middle part, or lower end of a partition 2 or a vertical wall 3 provided between an upper beam 41 and a lower beam 42 of a building.
[0015] The studs 2 and mullion walls 3 of a building are auxiliary small pillars or walls provided between pillars and between the upper beam 41 and the lower beam 42, and are usually provided as base materials for building walls. They are used particularly in structures where the pillars are far apart and wall partitions or wall base materials cannot be laid, and are covered with solid wall, gypsum board, plywood, veneer, etc. on the surface, making them invisible from the outside.
[0016] The seismic control structure 1 of the present invention can be applied without any particular restriction to any building in which studs 2 or mullion walls 3 are used, but it is particularly preferable for the building to be one of reinforced concrete (RC) buildings, steel frame (S) buildings, or steel reinforced concrete (SRC) buildings. Furthermore, if the building is a steel-framed (S-framed) building, it is preferable that the partition 2 or the vertical wall 3 is made of steel, and if the building is a reinforced concrete (RC) building or a steel-reinforced concrete (SRC) building, it is preferable that the partition 2 or the vertical wall 3 is made of steel, reinforced concrete, or reinforced steel concrete.
[0017] 1 and 5, the friction damper 5 used in the vibration control structure 1 of this embodiment is disposed at least at one of the upper end, lower end, and middle part of the partition 2 or the mullion wall 3 provided between the upper beam 41 and the lower beam 42. The friction damper 5 is a damper having a damping mechanism that utilizes the friction force acting as a resisting force in the opposite direction to the moving direction, and more specifically, as shown in Fig. 2, has a rod 51 (rod-shaped member) and a die 52 (annular member), and has a mechanism in which the outer surface of the rod 51 and the inner surface of the die 52 slide against each other to displace in the axial direction while maintaining a constant friction load, and the friction between the outer surface of the rod 51 and the inner surface of the die 52 converts energy such as earthquake motion into thermal energy and absorbs it.
[0018] The cross-sectional shape of the rod 51 used in the friction damper 5 in the direction perpendicular to the longitudinal direction may be circular, square, or the like, but is particularly preferably circular. There are no particular limitations on the materials of the components of the friction damper 5 as long as they have strength and wear resistance, but it is preferable that the rod 51 is made of a copper alloy and the die 52 is made of alloy tool steel, and it is preferable that the friction surfaces of the rod 51 and the die 52 are coated with a coating lubricant to obtain a more stable friction load. In another embodiment, the rod 51 and the die 52 are made of carbon steel pipes, and it is preferable that the inner surface of the die 52 is coated with a polytetrafluoroethylene friction material to obtain a more stable friction force between the rod 51 and the die 52.
[0019] The above-mentioned friction damper 5 has a relatively simple structure, and is therefore economical, has excellent maintainability, is highly durable against repeated operations, and is excellent in that it can provide high reliability as an energy absorbing device. Furthermore, since the friction damper 5 having the above-mentioned structure can adequately support the weight from above, when it is used in the seismic control structure 1 of the present invention, the earthquake energy absorbing performance is less affected by vertical loads.
[0020] FIG. 1 shows a seismic control structure 1 in which a friction damper 5 is installed on a partition 2. FIG. 1(A) shows an embodiment in which a friction damper 5 is installed in the middle part of the partition 2. FIG. 1(B) shows an embodiment in which a friction damper 5 is installed on the upper end part of the partition 2. FIG. 1(C) shows an embodiment in which a friction damper 5 is installed on the lower end part of the partition 2.
[0021] 1(A), the intermediate portion of the stud 2 is cut horizontally at its intermediate position to divide it into an upper stud 21 and a lower stud 22, and a space into which the rod 51 can be introduced is provided. The friction damper 5 is disposed in the space so that the longitudinal direction of the rod 51 is parallel and horizontal to the wall surface 6 on which the stud 2 is provided. Specifically, a bracket 510 and a rod base member 511 are fixed to the lower end of the upper stud 21 with bolts 53, and the rod 51 is fixed via the rod base member 511. A base plate 520 is fixed to the upper end of the lower stud 22 with bolts 53, and a die 52 is fixed to the base plate 520.
[0022] Although the rod 51 and the bracket 510 may be directly connected by welding or the like, it is preferable to connect flange-shaped rod base members 511 to both ends of the rod 51 and connect the rod 51 and the bracket 510 via the rod base members 511 as shown in Fig. 2. It is more preferable to connect the rod base member 511 and the rod 51 by providing a male thread at the end of the rod 51 and a female thread in the rod base member 511, so that a width adjustment function is imparted by screwing the male thread at the end of the rod 51 and the female thread in the rod base member 511 together, and the rod base member 511 can function as a width adjustment member.
[0023] Furthermore, the die 52 may be fixed to the upper end of the upper stud 21 by directly connecting the die 52, but it is preferable to interpose a base plate 520 between the die 52 and the upper end and connect with bolts 53. Furthermore, when connecting the die 52 and the base plate 520, it is preferable to provide a height adjustment function to the die 52 or the base plate 520 in consideration of fine adjustments to the installation position, etc.
[0024] Here, with regard to the fixing of the bracket 510 and the rod base member 511 with the bolts 53, and the fixing of the die 52 and the base plate 520 with the bolts 53, it is preferable to provide a countersunk hole 54 in the rod base member 511 or the base plate 520 and use a hexagon socket head bolt or the like as the bolt 53 so that the bolt head is hidden, as shown in Fig. 3. This prevents the bolt head from protruding, ensuring a wide operating stroke of the damper.
[0025] Furthermore, when the bracket 510 and the rod base member 511 are fixed by the bolts 53, the shape and interval of the bolt holes for attaching the bolts 53 can be appropriately set to adjust to absorb installation errors of the bolts 53. Specifically, for example, it is preferable to arrange more bolt holes at 45 degree intervals as shown in Fig. 4(A), or to provide play by forming the bolt holes in elongated holes as shown in Fig. 4(B). This makes it possible to improve the ease of installation of the friction damper 5.
[0026] The position of the middle part of the stud 2 where the friction damper 5 is to be installed can be appropriately determined taking into consideration the structure of the building, the position of the stud 2 itself, and the strength design, etc.; for example, it can be located at an evenly spaced midway between the top and bottom of the stud 2, a position toward the top from the middle, or a position toward the bottom from the middle, etc.
[0027] In the embodiment shown in FIG. 1(B) in which the friction damper 5 is disposed at the upper end of the stud 2, a space into which the friction damper 5 can be introduced is provided between the upper beam 41 and the upper end of the stud 2, and the friction damper 5 is disposed in the space. The fixing of the friction damper 5 is basically the same as in the embodiment shown in FIG. 1(A) in which the friction damper 5 is disposed at the middle part of the stud 2, but in this embodiment, a bracket 510 and a rod base member 511 are fixed to the upper beam 41 with bolts 53, and the rod 51 is fixed via the rod base member 511. In addition, a base plate 520 is fixed to the upper end of the stud 2 with bolts 53, and a die 52 is fixed to the base plate 520. Here, the size and width of the bracket 510 fixed to the upper beam 41 can be appropriately determined so as not to be damaged by earthquake motion.
[0028] Furthermore, in the embodiment shown in Fig. 1(C) in which the friction damper 5 is disposed at the lower end of the stud 2, a space into which the friction damper 5 can be introduced is provided between the lower beam 42 and the lower end of the stud 2, and the friction damper 5 is disposed in the space. Specifically, a bracket 510 and a rod base member 511 are fixed to the lower end of the stud 2 with a bolt 53, and a rod 51 is fixed via the rod base member 511. A base plate 520 is fixed to the lower beam 42 with the bolt 53, and a die 52 is fixed to the base plate 520. Note that the elimination of the protrusion of the bolt head in the fixation by the bolt 53 can be achieved by a configuration similar to that described in Fig. 1(a).
[0029] Next, an embodiment in which a friction damper 5 is provided on the mullion wall 3 will be described in detail. Fig. 5 shows a seismic control structure 1 in an embodiment in which a friction damper 5 is provided on the mullion wall 3, Fig. 5(A) shows an embodiment in which a friction damper 5 is provided in the middle of the mullion wall 3, Fig. 5(B) shows an embodiment in which a friction damper 5 is provided on the upper end of the mullion wall 3, and Fig. 5(C) shows an embodiment in which a friction damper 5 is provided on the lower end of the mullion wall 3.
[0030] In the embodiment shown in Fig. 5(A) in which the friction damper 5 is disposed in the middle of the mullion wall 3, the middle part of the mullion wall 3 is cut horizontally at the position where the wall is to be disposed, dividing the wall into an upper vertical wall 31 and a lower vertical wall 32, and a space into which the friction damper 5 can be introduced is provided, and the friction damper 5 is disposed in the space. Specifically, a bracket 510 is fixed to the lower end of the upper vertical wall 31 with a bolt 53, and a rod 51 is fixed to the bracket 510 via a rod base member 511. A base plate 520 is fixed to the upper end of the lower vertical wall 32 with a bolt 53, and a die 52 is fixed to the base plate 520.
[0031] The position of the middle part of the upright wall 3 where the friction damper 5 is arranged can be appropriately determined taking into consideration the building structure, the position of the upright wall 3, and strength design, etc., and can be, for example, the middle part of the upright wall 3, a position upward from the middle part, or a position downward from the middle part.
[0032] 5(B), in which the friction damper 5 is disposed at the upper end of the mullion wall 3, is basically the same as the case of disposing it at the middle part of the mullion wall 3 in FIG. 5(A), but in this embodiment, a bracket 510 is fixed to the upper beam 41 with a bolt 53, and a rod 51 is fixed to the bracket 510 via a rod base member 511. A base plate 520 is fixed to the upper end of the mullion wall 3 with a bolt 53, and a die 52 is fixed to the base plate 520. The size and width of the bracket 510 fixed to the upper beam 41 can be appropriately determined so as not to be damaged by earthquake motion.
[0033] 5(C), a space into which the friction damper 5 can be introduced is provided between the lower beam 42 and the lower end of the stud 2, and the friction damper 5 is disposed in the space. Specifically, a bracket 510 is fixed to the lower end of the stud 2 with a bolt 53, and a rod 51 is fixed to the bracket 510 via a rod base member 511. A base plate 520 is fixed to the lower beam 42 with the bolt 53, and a die 52 is fixed to the base plate 520.
[0034] The method for fixing the rod 51 and the die 52 to the upright wall 3 in the above embodiment shown in Figures 5(A) to (C) is the same as the method for fixing the rod 51 and the die 52 to the stud 2 in the above embodiment 1 shown in Figures 1(A) to (C).
[0035] In the seismic control structure 1 of the present invention, when the friction damper 5 is installed at any one of the upper end, middle part, or lower end part of the stud 2 or mullion wall 3, it is preferable that the distance between the upper beam 41 and the upper end part of the stud 2 or mullion wall 3, the distance between the lower end part and the upper end part of the middle part of the stud 2 or mullion wall 3, and the distance between the lower end part of the stud 2 or mullion wall 3 and the lower beam 42 are set to 0 to 50 mm.
[0036] Specifically, for example, in an embodiment of a vibration control structure 1 in which a friction damper 5 is disposed in the middle of a stud 2 as shown in FIG. 1(A), the distance between the divided lower stud 22 and the lower part of a bracket 510 fixed to an upper stud 21 is set to 0 to 50 mm.
[0037] In the embodiment of the vibration control structure 1 shown in Fig. 1(B) in which the friction damper 5 is disposed on the upper end of the upper beam 41 and the stud 2, the distance between the upper end of the stud 2 and the lower part of the bracket 510 fixed to the upper beam 41 is set to the above-mentioned predetermined distance. Furthermore, in the embodiment of the vibration control structure 1 shown in Fig. 5(C) in which the friction damper 5 is disposed on the lower end of the lower beam 42 and the stud 2, the distance between the lower beam 42 and the lower part of the bracket 510 fixed to the lower end of the stud 2 is set to the above-mentioned predetermined distance.
[0038] 5(A) to 5(C) also apply to the embodiments of the mullion wall 3. By setting the distance between the upper beam 41 and the upper end of the stud 2 or mullion wall 3, the distance between the upper and lower sides of the middle part of the stud 2 or mullion wall 3, and the distance between the lower end of the stud 2 or mullion wall 3 and the lower beam 42 to the above-mentioned predetermined distances, it is possible to achieve both the function of a stable stud 2 or mullion wall 3 and the function as a seismic control structure 1.
[0039] 6, when the distance between the upper beam 41 and the upper end of the mullion wall 3, the distance between the lower end and the upper end of the middle part of the mullion wall 3, and the distance between the lower end of the mullion wall 3 and the lower beam 42 are set to 0 mm, the lower surface of the upper beam 41, the upper surface of the lower beam 42, or the upper end, middle part, and lower end of the mullion wall 3 can be cut with a residual formwork made of steel plate, and a low-friction material can be interposed on the contact surface. Examples of the low-friction material in this case include graphite, molybdenum disulfide, polytetrafluoroethylene, and steel plate.
[0040] By setting the distance between the upper beam 41 and the upper end of the mullion wall 3, the distance between the lower end and the upper end of the middle part of the mullion wall 3, and the distance between the lower end of the mullion wall 3 and the lower beam 42 to 0 mm, there are no gaps and heat insulation performance can be ensured. Also, since the vertical load (self-weight, loaded weight) can be transmitted by the mullion wall 3, bending (flexural) deformation does not occur in the rod.
[0041] In addition, in the present invention, when the mullion wall 3 is a reinforced concrete (RC) building or a steel-reinforced concrete (SRC) building, a rectangular space may be provided in advance in the upper beam 41 or part of the mullion wall 3, or in the lower beam 42 or part of the mullion wall 3, and a friction damper 5 may be installed within the space.
[0042] The operation of the vibration control structure 1 of the present invention when an earthquake motion acts on it will be described in detail below. For example, in the case of the vibration control structure 1 of the embodiment shown in Fig. 1(B), when an earthquake motion acts on the upper beam 41 in the right direction (arrow direction) as shown in Fig. 7, a force that moves the rod 51 of the friction damper 5 to the right also acts, but the die 52 suppresses this movement and a force that moves the rod 51 to the left relatively acts from the center of the rod 51. At that time, the friction between the rod 51 and the die 52 converts the earthquake energy into thermal energy, thereby exerting a vibration control effect.
[0043] The vibration control effect provided by the friction damper 5 can be obtained in both the vibration control structure 1 made of partition 2 shown in Figures 1(A) and (C) and the vibration control structure 1 made of vertical walls 3 shown in Figures 5(A) to (C).
[0044] The above describes the vibration-damping structure 1 of the present invention based on an embodiment, but the vibration-damping structure 1 of the present invention is not limited to the above embodiment, and various modifications are possible within the scope that does not deviate from the gist of the structure.
[0045] For example, in the embodiment shown in Figs. 1 and 5 above, the friction damper 5 is arranged such that the rod 51 is fixed to the upper side and the die 52 is fixed to the lower side, but as shown in Fig. 8, it is also possible to reverse this and arrange the die 52 to be fixed to the upper side and the rod 51 to be fixed to the lower side.
[0046] In addition, in the case of a vibration control structure 1 in which friction dampers 5 are provided on a mullion wall 3 as in the embodiment shown in Fig. 5, for example, it is possible to provide multiple friction dampers 5 by dividing the structure into sections in the horizontal direction (in series) as shown in Fig. 9, or to directly connect multiple friction dampers 5 as shown in Fig. 10. This makes it possible to improve the vibration control performance of the vibration control structure 1 by more than two times while saving space.
[0047] According to the vibration control structure 1 of the present invention configured as described above, by using a compact friction damper 5 that fits within the wall thickness of a building, it is possible to provide a vibration control structure 1 that fully retains the functions of the studs 2 and mullion walls 3 and has excellent design that is not noticeable from the outside. In addition, since the friction damper 5 can be easily accessed from inside the room, it is easy to perform retrofit installation, replacement, and maintenance. [Explanation of symbols]
