Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rigidity adjusting wall panel having rigidity and damping property only for a minute level of vibration such as a vibration generated by a vehicle passing through a road or a vibration generated by walking indoors. The present invention relates to a method for mounting the wall panel.

[0002]

2. Description of the Related Art Generally, in a building having a steel frame structure, structural calculation is performed based on preset design criteria. The design criteria mainly focus on the horizontal force acting on the structure due to the assumed earthquake, and target vibrations having a relatively large amplitude. Further, in a high-rise building or a super-high-rise building, it is common to provide a structure having a vibration damping function and a damping function in order to secure habitability against a disturbance such as wind.

For example, the technique disclosed in Japanese Patent Laid-Open No. 64-1877 relates to a bearing wall mounting device applied to a seismic resistant wind control device for a reinforced concrete structure, and particularly, when a strong wind or a small or medium earthquake occurs. The purpose is to maintain habitability.

Further, the technique disclosed in Japanese Patent Laid-Open No. 64-66379 relates to an earthquake-resistant wall having a built-in vibration damping function used in a steel-framed high-rise building. Is intended to be reduced.

On the other hand, a small vibration such as a vibration generated by a vehicle passing through a road or a vibration generated by walking indoors may act on the middle and low-rise buildings. And buildings at the vibration level (especially, middle and low-rise steel-framed buildings such as residential buildings)
In reality, not only the skeleton but also the secondary members such as the book wall and the partition wall greatly contribute to the rigidity of.

[0006]

When minute vibrations act on a building, depending on the arrangement and amount of secondary members, a twist may be generated in the building, regardless of the result of the structural calculation performed properly. There is a possibility that the wall will be adversely affected. In other words, if the secondary members are placed without limitation on the frame constructed according to the result of the structural calculation, the eccentric distance between the center of gravity and the rigid center becomes large, and even if a slight external force (microvibration) acts, it will be twisted. There is a problem of causing vibration.

Further, when the length in the frontage direction of a building is smaller than the length in the column direction, the amount of secondary members in the frontage direction is insufficient, so that there is a problem that the rigidity against minute vibrations in this direction is insufficient. is there.

If the number of walls is extremely small, the rigidity and damping at the minute vibration level may be insufficient. Therefore, it may be reinforced with a high-rigidity member for the purpose of increasing the rigidity of the building, but depending on the method of mounting the member, stress may concentrate when a large earthquake occurs and adversely affect the entire building. Occurs.

In addition, as a reinforcing method against microvibration in a building with a steel frame structure, a brace is arranged between the upper and lower beams to increase the rigidity. However, if a small external force acts unless the cross-sectional area of the brace is considerably increased. There is a problem that the burden capacity is small.

Further, the technique disclosed in Japanese Patent Laid-Open No. 64-1877 and the technique disclosed in Japanese Patent Laid-Open No. 64-66379 are intended for high-rise buildings or super high-rise buildings, and require a large amount of equipment and structure. Therefore, there is a problem that it is not suitable for middle- and low-rise buildings such as residential buildings.

An object of the present invention is to have rigidity and damping properties only for minute vibrations such as traffic vibrations and vibrations caused by walking indoors, and to adjust the rigidity of the entire building on which the minute vibrations act to improve comfortability. An object of the present invention is to provide a structure of a rigidity adjusting wall panel that can be maintained.

[0012]

In order to solve the above problems, a typical structure of a rigidity adjusting wall panel according to the present invention is to directly mount a plurality of panel units between upper and lower beams in a steel structure. Alternatively, the panel units are indirectly connected to the upper and lower beams, and the adjacent panel units are tightly connected via a plurality of damper units having a viscoelastic body.

The method for mounting the rigidity adjusting wall panel is such that a plurality of panel units are arranged between the upper and lower beams in the steel frame structure and the upper and lower beams are installed directly or through two studs installed at a predetermined interval. Connected to the beam, the upper and lower ends of the panel unit are tightly connected by a joint material, and a plurality of damper units having a viscoelastic body are arranged between adjacent panel units with a predetermined gap and the damper units are interposed. It is characterized by tightly connecting the panel unit.

[0014]

With the above structure of the rigidity adjusting wall panel (hereinafter referred to as "wall panel structure"), it is possible to construct a wall surface having rigidity and damping between the upper and lower beams with a simple structure. That is,
By arranging a plurality of panel units between the upper and lower beams and directly or indirectly connecting them to the upper and lower beams, and adhering adjacent panel units via a plurality of damper units having a viscoelastic body, the rigidity and A wall surface having a damping property can be formed.

In the above wall panel structure, the panel units are directly or indirectly connected to each other between the upper and lower beams. When the microvibration acting on the skeleton is transmitted to the panel unit, the force corresponding to the microvibration is borne by the shear deformation, so that high initial rigidity can be exhibited. Further, since the panel unit is tightly connected via the damper unit, it is possible to absorb the shear deformation generated in the panel unit and quickly damp the minute vibration acting on the building.

Further, by adopting the above wall panel structure corresponding to the arrangement position of the secondary member in the building, the eccentric distance between the center of gravity and the rigid center can be adjusted to adjust the rigidity of the building. Therefore, it is possible to prevent a twist that may occur in the frame when a minute vibration acts on the building.

Further, in the above-mentioned method of mounting the rigidity adjusting wall panel, a plurality of panel units are arranged between the upper and lower beams and are directly connected to each other, or are connected to the upper and lower beams through studs installed at a predetermined interval, and adjacent to each other. By tightly connecting the panel units via a plurality of damper units arranged between the panel units, a wall panel structure can be formed between the upper and lower beams.

The rigidity adjusting wall panel A includes two studs 3 provided between an upper beam 1 and a lower beam 2 in a steel frame structure, two panel units 4 arranged between the studs 3, and a panel. A damper unit 5 is arranged between the units 4 with a predetermined interval, and the stud 3 on one side and the panel unit 4 adjacent to the stud 3 are tightly connected to each other, and the stud 3 on the other side and the stud 3 are connected to each other. Adjacent panel units 4 are tightly connected, and further panel units 4 and 4 are tightly connected by a damper unit 5.

The studs 3, panel unit 4, and damper unit 5 are supplied to the construction site in the form of finished products produced in advance in a factory. Then, the wall panel structure A can be configured by tightly connecting the above-mentioned members to each other with the upper and lower beams 1 and 2 or tightly with each other by a tightening member such as a bolt and a nut.

The stud 3 is formed to have a length equal to the distance between the upper and lower beams 1 and 2 (inter-beam distance), and both ends in the longitudinal direction are fixed to the beams 1 and 2. Therefore, the minute vibrations acting on the beams 1 and 2 are transmitted to the studs 3. Further, on one side surface of the stud, as shown in a second embodiment described later, means for tightly connecting the panel unit 4 is formed.

As shown in (b), plates 5b, 5c formed in a predetermined shape are attached to the front and back surfaces of a viscoelastic body 5a made of plastic rubber or elastic rubber and having damping properties. The viscoelastic body 5a has a function of attenuating minute vibrations acting on 5c. Further, the damper unit 5 is arranged between the panel units 4 and tightly connects these panel units 4. Therefore, the plates 5b,

Then, the minute vibrations generated in the upper and lower beams 1 and 2 are transmitted from the beams 1 and 2 to the stud 3, and are transmitted to the plates 5b and 5c of the damper unit 5 through the stud 3 and the panel unit 4.

Damper unit 5 to which minute vibration is transmitted
Then, the microvibration acting on the plates 5b and 5c is transmitted to the viscoelastic body 5a, and the viscoelastic body 5a is deformed according to the microvibration. Therefore, the minute vibration is absorbed or damped by the elastic body 5a.

Next, the wall panel structure B according to the second embodiment will be described with reference to FIGS. In the figure, the same parts and parts having the same functions as those of the first embodiment described above are designated by the same reference numerals and the description thereof will be omitted.

The wall panel structure B according to the present embodiment is constructed so as to be able to cope with a variation in the distance between the upper and lower beams 1 and 2 due to a machining tolerance or a construction tolerance, and It is configured so that the panel structure B is prevented from being deformed in the out-of-plane direction and the force is properly transmitted in the damper unit 5, whereby the damping property can be maintained.

In particular, the wall panel structure B according to this embodiment is
For example, if a complaint about vibration occurs after the building is completed, the members should be divided and the weight should be reduced so that the complaint can be dealt with by installing the wall panel structure B inside the partition wall or on the back surface of the book wall. It is constructed so that it can be scaled and the workability in installation work can be improved.

As shown in FIGS. 3 and 5, the stud 3 is a stud member 3 having a length which is approximately ½ of the distance between the upper and lower beams 1, 2.
a and 3b, and each stud member 3a and 3b is connected to the adjusting joint 6
The length can be adjusted by connecting by.

One stud member 3a is formed so that it can be fixed to the upper beam 1, and the other stud member 3b is formed so that it can be fixed to the lower beam 2, and the upper end side of the stud member 3a and the stud member 3b can be formed. A fixing member 3c is provided on the lower end side and fixed in surface contact with the corresponding beams 1 and 2, respectively. In addition, bolt holes 3e are formed at opposite ends of the stud members 3a and 3b.
The connection plate 3d formed with is fixed.

The adjusting joint 6 is composed of a strip plate and has a bolt hole 6a and a long hole 6b. Therefore, the length of the stud 3 including the stud members 3a and 3b can be adjusted within the range of the long hole 6b, and even when the distance between the upper and lower beams 1 and 2 changes, the stud member 3a, It is possible to install the stud 3 in a state in which the fixing member 3c provided on the portion 3b is surely brought into contact with the beams 1 and 2.

By constructing the studs 3 as described above, there is no possibility that a gap will be formed between the beams 1 and 2 and the studs 3, and the minute vibrations generated in the beams 1 and 2 will surely be transmitted to the studs 3. It is possible to communicate.

A bracket 7 serving as a means for tightly connecting the panel unit 4 in the longitudinal direction is fixed to one side surface of the stud members 3a and 3b. The bracket 7 is provided at a position corresponding to the mounting direction and thickness of the panel unit 4 to be tightly bound. That is, in this embodiment, the panel units 4 are not arranged in the same plane, but are arranged at positions symmetrical with respect to the line connecting the centers of the studs 3, as shown in FIG. . Therefore, the bracket 7 is provided at a position separated from the center of the stud 3 by a predetermined distance.

In this embodiment, steel is used as the material of the panel unit 4. This panel unit 4 is
A plate 4b is fixed to a frame member 4a formed by combining L-shaped members, and a reinforcing member 4c and a stiffener 4d are arranged at positions where the damper unit 5 is tightly connected. Then, by arranging the two panel units 4 in the vertical direction and tightly connecting them to each other with bolts, nuts, etc., they are treated as one panel unit as in the first embodiment.

A plurality of tightening plates 8 serving as tightening means are fixed at predetermined intervals on the side surface of the frame member 4a where the damper unit 5 is tightened. The binding plate 8 is formed in an L shape, and one piece is fixed to the frame member 4a of the panel unit 4, and the other piece is projected and tightly connected to the plates 5b and 5c of the damper unit 5.
Further, the protruding piece of the binding plate 8 is arranged so as to be located on a line connecting the centers of the two studs 3 when the panel unit 4 is tightly bound to the stud 3.

The binding plates 8 are evenly provided in the up-down direction about the vertical center of the connected panel unit 4, and a reinforcing member 4c is provided at a position corresponding to the binding plate 8 of the panel unit 4. It is arranged.
Therefore, it is possible to reliably transmit the minute vibrations transmitted to the panel unit 4 via the studs 3 from the binding plate 8 to the damper unit 5.

A panel unit 4 arranged between the studs 3
Has upper and lower ends connected by a joint material 9. The joint material 9 is formed by a flat bar and is used for the panel unit 4
Are fastened to the frame members 4a corresponding to the upper and lower ends by bolts and nuts.

The joint material 9 restrains the panel unit 4 tightly connected via the damper unit 5 to prevent the unit 4 from being deformed in the out-of-plane direction in response to a force acting from the outside. It is a thing. That is, when the panel unit 4 is deformed in the out-of-plane direction in response to the minute vibration transmitted through the stud 3, the damper unit 5 is separated from the line connecting the studs 3, and the linearity of the damper unit 5 is obstructed, which is effective. It is intended to prevent that it becomes impossible to maintain a good damping property.

In this embodiment, the thickness of the studs 3 and the thickness of the panel unit 4 are smaller than the outer dimensions of the main pillars constituting the frame of the building. Therefore, when the wall panel structure B is installed between the upper and lower beams 1 and 2, it can be housed inside the partition wall or on the back surface of the book wall.

Next, the wall panel structure B is provided between the upper and lower beams 1 and 2.
The procedure for attaching the will be described. First, the upper and lower beams 1,
Install stud 3 between 2 That is, the stud members 3a and 3b
Connection plates 3d are arranged to face each other and the adjustment joint 6 is temporarily fixed, and in this state the fixing member 3c is fixed to each of the beams 1 and 2, and then the stud members 3a, 3 are inserted via the adjustment joint 6.
By tightly connecting b, even if the distance between the upper and lower beams 1 and 2 changes, it is possible to install them without forming a gap between these beams 1 and 2 and the stud 3. .

Next, the panel unit 4 is tightly connected to the bracket 7 of each stud 3. At this time, when the length of the stud 3 is adjusted when the stud 3 is fixed to the upper and lower beams 1 and 2, a gap may be generated between the panel units 4 arranged in the up and down direction. In this case, a liner (not shown) is provided between the panel units 4 for tight connection. Further, the damper unit 5 is tightly connected to the previously designated tightly connecting plate 8 to tightly connect the panel units 4 together. After that, the wall panel structure B can be formed by tightly connecting the joint members 9 to the upper and lower ends of the panel unit 4.

As described above, the stud members 3a, 3b, the adjustment joint 6, the panel unit 4, the damper unit 5, and the joint material 9 which are manufactured in advance in the factory are sequentially tightened by the tightening members such as bolts and nuts, so that the wall It is possible to construct the panel structure B. For this reason, it is possible to standardize the work and shorten the construction period, and it is economically advantageous to eliminate the work for site matching at the construction site.

In the wall panel structure B, there is no possibility that a gap will be created between the upper and lower beams 1 and 2 and the stud 3. Therefore, the small vibrations acting on the beams 1 and 2 are surely transmitted to the stud 3,
And it is transmitted from the stud 3 to the panel unit 4. The microvibration transmitted to the panel unit 4 is transmitted to the binding plate 8 via the frame member 4a and the reinforcing member 4c, and further,
It is transmitted to the damper unit 5 tightly bound to the tight binding plate 8. And the plates 5b, 5 of the damper unit 5
The minute vibration transmitted to c is absorbed or attenuated by the viscoelastic body 5a.

Wall panel structures A and B constructed as described above
In this case, the number of damper units 5 arranged between the panel units 4 is set based on the damping characteristics of the damper units 5 and conditions such as a presumed minute vibration level. That is, by appropriately setting the number of arranged damper units 5, it is possible to extremely easily adjust the rigidity and damping properties of the wall panel structures A and B according to desired conditions.

Therefore, in designing a building with a steel frame structure, when the condition of the minute vibration level acting on the building is set, the layout of the damper unit 5 is arranged without making any design change to the panel unit 4 and the damper unit 5. By only setting the number, it becomes possible to construct the wall panel structures A and B having rigidity and damping properties that can correspond to the setting conditions.

[0047]

As described above in detail, the wall panel structure according to the present invention can be constructed by tightly connecting the stud, the panel unit, and the damper unit with tightening members such as bolts and nuts. Further, each of the above-mentioned members can be factory-produced in advance, and a wall panel structure can be constructed by performing a work of binding the carried-in members in a predetermined order at a construction site. Therefore, the construction period can be shortened, and unnecessary members can be reduced to reduce the cost.

As described above, since the panel unit and the damper unit constituting the wall panel structure are supplied in the completed state, the mounting work and the carrying work for the upper and lower beams are easy, and even after the building is completed. Can be installed easily. In particular, when the studs are divided into two parts, the members forming the studs become light in weight, which facilitates the installation work and the transportation work, especially the work when installing the wall panel structure after the building is completed. Can be done.

Further, when constructing the wall panel structure, it is possible to appropriately set the number of damper units to be arranged between the panel units, and it is possible to easily attach the set damper units. For this reason, it is possible to easily design and configure a wall panel structure that can appropriately meet the design conditions of a unique building.

Further, by constructing the studs by dividing the studs in the vicinity of the center, it is possible to reliably transmit the microvibration generated in each beam to the wall panel structure without creating a gap between each beam and the studs. It can exhibit rigidity and damping properties.

By connecting the upper and lower ends of the panel unit with a joint material, it is possible to prevent the wall panel structure from being deformed in the out-of-plane direction, and to properly transmit the force in the damper unit. You can do it.

Further, in the wall panel structure according to the present invention, when the microvibration acting on the skeleton is transmitted to the panel unit, a force corresponding to the microvibration is borne by the shear deformation to exhibit a high initial rigidity. Moreover, since the panel unit is tightly connected via the damper unit, it is possible to absorb the shear deformation generated in the panel unit and quickly damp the minute vibration acting on the building.

Further, by adopting the wall panel structure corresponding to the position where the secondary member is arranged in the building, the eccentric distance between the center of gravity and the rigid center can be adjusted to adjust the rigidity of the building. Therefore, it is possible to prevent a twist that may occur in the frame when a minute vibration acts on the building.

The wall panel structure according to the present invention can be installed in the partition wall or on the back surface of the book wall. For this reason,
It has the feature that the rigidity of the building can be adjusted without changing the plan.
