Description

  The present invention relates to a vibration isolating structure for a building.

Conventionally, various anti-vibration structures for buildings are known to protect the buildings against ground shaking such as earthquakes.
For example, Patent Documents 1 to 3 describe and describe a structure that protects a building from vibrations such as an earthquake by using a foundation of the building as a damping structure.

  The structures described in Patent Documents 1 to 3 include a ground side foundation having a flat upper surface formed on the ground and a housing side foundation having a flat lower surface formed on the lower surface of the building body. It is a vibration-proof structure in which the building main body is installed on the housing-side foundation, with the housing-side foundation being slidable or rolling in a horizontally movable state.

  In Patent Document 4 and Patent Document 5, diagonal members such as a cane (Patent Document 4) and a brace (Patent Document 5) passed diagonally from a pillar of a building to a ceiling beam or an upper floor beam, A structure that reinforces a pillar and that uses this diagonal as a vibration-damping structure to protect the building is described.

  However, in the structures described in Patent Documents 1 to 3, when the ground shakes due to an earthquake or the like, the ground side foundation shakes. Then, in order to keep the position of the building body as it is, the house-side foundation moves horizontally with the building body on the shaking ground-side foundation to reduce the shaking of the building body. That is, the ground body foundation formed on the ground and the position of the building body move relatively horizontally to protect the building body from vibrations such as earthquakes.

This will be described with reference to FIG.
In FIG. 10, reference numeral 100 denotes a ground, and the ground 100 is provided with a ground-side foundation 200 having a substantially flat upper surface.
Reference numeral 300 denotes a building body, and a substantially flat housing-side foundation 400 is provided on the lower surface of the building body 300.
Then, as shown by the solid line in FIG. 10, the building main body 300 is installed on the ground 100 with the housing-side foundation 400 placed on the ground-side foundation 200 so as to be movable in the horizontal direction.

When the ground 100 shakes due to an earthquake or the like, the position of the building body 300 moves relative to the ground 100 as shown by the dotted line in FIG. 10 and vibrates as shown by the arrow.
At this time, if there is a fixed object 450 such as a building or a tree that vibrates with an earthquake next to it, there is a risk that the building body 300 may collide with the fixed object 450 such as an adjacent building or tree.
Therefore, in order to prevent the building main body 300 from colliding with a fixed object 450 such as an adjacent building or tree by horizontally moving, the distance between the building main body 300 and the adjacent fixed object 450 such as a building or tree is increased. It is inconvenient to do.

  Further, a member that connects the ground 100 and the building main body 300, such as a pipe that connects to the equipment installed in the building main body 300, is destroyed by the relative horizontal movement of the building main body 300 and the ground 100. Therefore, it is necessary to make this member follow the relative movement of the building main body 300 and the ground 100, and there is a problem that the cost of piping and the like increases.

  In addition, the structure described in Patent Document 4 and Patent Document 5 is a structure in which a cane (Patent Document 4) or a brace (Patent Document 5) is passed from a building column to a ceiling beam or an upper floor beam. At the same time as reinforcing the beam, this brace or brace is used as a damping structure to protect the building body from vibrations such as earthquakes. This structure, action and problems will be described with reference to FIG.

In FIG. 11, 500 is the ground. A foundation 600 is provided on the ground 500, and a two-story building 700 is installed on the foundation.
In this building 700, the pillars 710 and the cross members 720 are reinforced with a cane 800 that is obliquely passed from a pillar 710 to a cross member 720 such as a ceiling beam, a floor beam on the upper floor, and a roof beam of a roof.
As shown in FIG. 11 (b), the connecting structure of this cane 800 and the column 710 or the cross member 720 is provided in the round hole 750 provided in the column 710 or the cross member 720 and the cross stick 800. The bolt 900 passed through the long hole 850 is connected to the nut 910 screwed into the bolt 900.

  Because of this structure, when the ground 500 vibrates due to a large force such as an earthquake, the column 710 vibrates in a tilted manner, and the angle of the cross member 720 changes in the column 710, and this change causes the change of the wand 800. Although the length changes, the bolt 900 moves through the long hole 850 to absorb the force changing the length, and the shaking of the ceiling beam and the upper floor beam 720 indicated by the arrow is reduced.

Because of this structure, the vibration of the upper floor above the ceiling beam and the upper floor beam 730 is small and extremely convenient. However, the floor beam on the first floor vibrates together with the ground 500, so The vibration of the first floor where people live is not reduced.
In addition, if the vibration such as an earthquake stops while the bolt 900 is moved along the long hole 850 due to the vibration of the earthquake or the like, the original state is not restored and the building remains in a deformed state and the building is distorted. Remain.

Further, in the structure described in Patent Document 6, the amount of oil contained in the hydraulic chamber is controlled by a computer to absorb vibration, so that a large-scale control device is required and the equipment cost is high. There is a problem of becoming higher.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an inexpensive anti-vibration structure for a building that can reduce the vibration of the entire building including the building on the first floor without the horizontal movement of the building body on the ground side foundation.

The foundation in the present invention is provided on the ground, and the building body is built thereon, and may be a cloth-type foundation or a bundle-type foundation.
And although many conventional foundation parts are made of concrete, the foundation part of the present invention is significantly different from the conventional foundation part in that it is made of steel.
There are two types of diagonal materials in the present invention: the basic diagonal material provided in the foundation and the diagonal material in the building provided in the building.

The diagonal member of the foundation is a beam member that passes from the vertical member to the horizontal member or the adjacent vertical member in an oblique direction, and is preferably a diagonal member such as a cane or a brace.
In addition, the diagonal members in the building are beam members that pass diagonally from a column to a horizontal member that is one of a ceiling beam, a floor beam on the upper floor, or a roof beam on a roof, or to an adjacent column. Diagonal materials such as braces and braces are suitable.

The building in the invention described in claim 1 includes all of various types of buildings. For example, the building may be a building that is built on-site, or a building that is manufactured as a unit building or an assembly house that assembles the building unit at the site. Also, this unit building may be a steel-based unit building or a wooden unit building.
In particular, a building in which building units as claimed in claim 2 and claim 3 are assembled is suitable.

A vibration damping structure in which a damper is sandwiched between them is preferable.

  According to the third aspect of the present invention, the ceiling beam, the upper floor beam, and the cross-beam that is the roof beam of the roof are a building in which the ceiling beam, the floor beam, and the roof beam are separate beams. In a building called a ceiling beam, the ceiling beam is the same as the ceiling beam, and the ceiling beam on the top floor is the same as the roof beam. However, in buildings called roof beams, they are called roof beams.

(Function)
The invention according to claim 1 is a building vibration-proof structure in which a building body is built on a foundation portion, and the foundation portion is provided with a substantially vertical vertical member made of steel frame. On the upper side, there is provided a cross beam projecting in a substantially horizontal direction from the front end of the vertical member or a floor beam on the first floor of the building main body, and the vertical member is from the vertical member to the cross member or the adjacent vertical member. As shown below, the floor beams on the first floor are less likely to sway, and as a result, the entire building is less likely to sway. .

  That is, when the ground is shaken, in the conventional concrete foundation, this foundation is hardly deformed, so this vibration is directly transmitted to the building body, and the building body shakes in the same way as an earthquake. In the first aspect of the invention, since the longitudinal member of the base portion is made of flexible steel, the longitudinal member made of steel vibrates in the direction of bending in the transverse direction, and the angle between the longitudinal member and the transverse member is changed. However, the length of the diagonal member passed in an oblique direction from the vertical member to the horizontal member or the adjacent vertical member changes, but this diagonal member has a vibration suppression structure. The material absorbs vibration and the vibration of the cross member is reduced.

  In this way, even if the ground shakes, the diagonal material with a vibration-damping structure absorbs the shaking of the ground, and the horizontal beam or the horizontal beam that is the first-floor floor of the building body is reduced. Or the shaking of the whole building main body including the part of the building main body above the floor beam of the first floor of a building, ie, the first floor, becomes small.

The invention according to claim 2 relates to the invention according to claim 1, and since the building main body is a unit building main body in which a plurality of building units are assembled, diagonal members are attached to the foundation and assembled at the factory. By simply installing the unit building, or by installing the diagonal after installing the unit building on the foundation, it can be made a vibration-proof structure and is extremely easy to construct.
In particular, in the case where the building unit is a steel-based building unit that is generally said to be easily shaken, the shake is reduced and a preferable building is obtained.

A cross member, which is one of beams, is provided, and the column is reinforced with a diagonal member having a vibration control structure that is obliquely passed from the column to the cross member or an adjacent column. As in the invention of the present invention, the vibration of the building unit on the first floor is small, and even if the building unit on the first floor is shaken, the vibration control structure provided between the column on the first floor and the ceiling beam or the floor beam on the upper floor The diagonal materials in the building absorb the shaking of the building unit on the first floor, and the shaking of the building unit on the upper floor becomes smaller than before.

In this way, the entire unit building including the building unit on the first floor is difficult to shake, and is a building with good habitability.
The invention according to claim 4 relates to the vibration-proof structure of the unit building according to any one of claims 1 to 3, wherein the diagonal member of the vibration control structure includes a first diagonal member, a damper, and a second diagonal member. It is a rod-like body connected in a straight line in this order, and this damper is a vibration control device that combines the elasticity of an elastic body and the viscosity of a viscous liquid. Even if a force to change the length of the material is applied, the vibration is greatly absorbed by the vibration control effect of the elastic body of the vibration isolator that is the damper and the viscosity of the viscous liquid, and the building is difficult to vibrate When the vibration ends, the building unit returns to a predetermined position due to the elasticity of the elastic body, and the building after the earthquake is not distorted.

  The invention according to claim 1 is a vibration-proof structure of a building in which a building body is built on a foundation portion, and the foundation portion is provided with a substantially vertical vertical member made of steel frame. On the upper side, there is provided a cross beam projecting in a substantially horizontal direction from the front end of the vertical member or a floor beam on the first floor of the building main body, and the vertical member is from the vertical member to the cross member or the adjacent vertical member. Because it is reinforced with a diagonal material with a vibration control structure that absorbs vibrations passed in an oblique direction, even if the ground shakes due to an earthquake, the diagonal material with the vibration suppression structure absorbs the vibration of the ground As a result, the shaking of the first floor beam of the horizontal beam or the building body is reduced, and the building body above the horizontal foundation or the first floor beam of the building, that is, the whole building body including the first floor part is shaken. Becomes smaller.

  The invention according to claim 2 relates to the invention according to claim 1, and since the building body is a unit building body in which a plurality of building units are assembled, diagonal members are attached to the foundation and assembled at the factory. By simply installing the unit building or installing the diagonal building after installing the unit building on the foundation, it can be made a vibration-proof structure and is extremely easy to install.

The invention according to claim 3 relates to the invention according to claim 2, wherein the building unit is provided with a substantially vertical column, a ceiling beam, an upper floor beam, and a roof roof above the column. 2.

In this way, the entire unit building including the building unit on the first floor is difficult to shake, and is a building with good habitability.

  The invention according to claim 4 relates to the vibration isolating structure for a building according to any one of claims 1 to 3, wherein the diagonal member of the damping structure includes a first diagonal member, a damper, and a second diagonal member. It is a rod-like body that is connected in a straight line in order, and this damper is a vibration control device that combines the elasticity of an elastic body and the viscosity of a viscous liquid. The vibration is greatly absorbed by the vibration control action of the elastic body of the vibration isolator which is the damper and the viscosity of the viscous liquid even if the force to change the length of the vibration is applied, and the building is difficult to vibrate. When the vibration is finished, the building unit is returned to a predetermined position by the elasticity of the elastic body, and the building after the earthquake is not distorted.

Next, embodiments of the present invention will be described with reference to examples.
(Example 1)
1 to 4 show an embodiment of the present invention, FIG. 1 is a perspective view of a building, FIG. 2 is a perspective view showing a main part of a foundation on which a building unit on the first floor is installed, and FIG. FIG. 4 is a sectional view showing a main part of the diagonal member.

  1 to 4, U is a building. As shown in FIG. 1, nine building units 2 are installed on a base portion 1 to form a first floor. Nine building units 2 are installed on a building unit 2 on the floor to form a second floor, and a roof panel 3 is attached on the building unit 2 on the second floor.

  As shown in FIG. 3, the building unit 2 constituting the building U has four steel square cylindrical columns 21 erected at four rectangular corners, and a rectangular lower end portion of the four columns 21. 4 steel cross-section floor beams 22 connected along the sides of the steel, and four steel cross-section U-shapes connecting the upper ends of the four columns 21 along the rectangular sides. The elongate ceiling beam 23, the column 21, and the ceiling beam 23 have a skeleton composed of diagonal members 4 in a building that are crossed and connected in an oblique direction.

In the building unit 2, a steel square tubular floor beam 24 is passed to the opposite floor beam 22 of the skeleton, and a wooden floor joist 25 is attached on the floor beam 24. A particle board floor material 26 is attached on the joist 25 to form a floor, and a wooden ceiling edge 27 is attached to the opposite ceiling beam 23, and is attached to the lower surface of the ceiling edge 27. The ceiling surface material 28 of the gypsum board is attached to form a ceiling.
Further, in the place where the outer wall is provided, an intermediate column 29 is passed between the floor beam 22 and the ceiling beam 23, and an outer wall panel and an inner wall panel (not shown) are attached to the intermediate column 29, and between the outer wall panel and the inner wall panel. Glass wool insulation is attached to form the outer wall.

As shown in FIG. 2, the base portion 1 is a bundle type, and as shown in FIG. 2, a concrete base 11 embedded in the ground 9, and a longitudinal member of a steel cross section U-shaped long body standing on the base 11. 12, a cross member 13 which is a transverse beam of a U-shaped cross section made of steel and attached substantially horizontally to the upper end of the vertical member 12, and the vertical member 12 and the cross member 13 are passed in an oblique direction. It consists of a basic diagonal material 5 which is a cane.
In this case, the ground 9 may be a solid foundation.
The building unit 2 is installed on the cross member 13 of the foundation 1.

Since the diagonal member 4 and the basic diagonal member 5 in the building have substantially the same structure, when both are shown, it is simply referred to as the diagonal member H.
As shown in FIG. 4, the diagonal material H includes a first diagonal material H <b> 1, a damping device 6 that is a damper, and a second diagonal material H <b> 2 connected in a substantially straight line.
The vibration damping device 6 includes a cylindrical cylinder 61 having lids attached to both sides thereof, a piston 62 that is reciprocally attached in the cylinder 61, and a spring provided between the piston 62 and the lids on both sides. It consists of a spring 63 and a viscous liquid 64 sealed in a cylinder 61, and a small gap 65 is provided between the cylinder 61 and the piston 62.

The piston rod 65 attached to the piston 62 is connected to the first diagonal material H1, and one lid of the cylinder 61 is connected to the second diagonal material H2.
As shown in FIGS. 2 and 3, the diagonal member H is passed diagonally from the vertical member 12 to the horizontal member 13 or from the column 21 to the ceiling beam 23, and the first diagonal member H <b> 1 and the second diagonal member H <b> 1. One of the diagonal members H2 is connected to the vertical member 12 and the column 21, and the other is connected to the cross member 13 and the ceiling beam 23.

The vibration damping action of the diagonal material H will be described.
When the ground 9 vibrates due to an earthquake or the like, the vertical member 12 or the column 21 vibrates, resulting in vibration in which the angle between the vertical member 12 or the column 21 and the cross member 13 changes. As a result, the length of the diagonal member H changes. Vibration.
When this vibration is observed in detail, first, when the ground 9 moves to one side due to an earthquake or the like, the vertical member 12 and the column 21 are bent and inclined, and due to this inclination, the first diagonal member H1 and the second diagonal member of the diagonal member H. The distance of H2 changes, and the piston 62 moves in the cylinder 61. A viscous liquid 64 is sealed in the cylinder 61, and this viscous liquid 64 is provided between the cylinder 61 and the piston 62. It moves only through the small gap 65 formed.

At this time, the greatest force is required when the viscous liquid 64 starts to move, and the speed becomes gradually higher when the viscous liquid 64 starts to move.
However, the spring springs 63 provided on both sides of the piston 62 move even with a relatively small force when the piston 62 starts to move. However, as the piston 62 moves, the spring spring 63 is restored to the original state with a force proportional to the moved distance. Trying to return. There is a time difference between the viscous resistance force of the viscous liquid 64 and the elastic resistance force of the spring spring 63.

Although it moves in this way, before the movement is sufficiently completed, the longitudinal member 12 and the column 21 are moved in the opposite direction by the vibration such as an earthquake, and the piston 62 is moved in the opposite direction.
Thus, the vibration is remarkably reduced by the viscous force of the viscous liquid 64 and the resistance force having a time difference caused by the elasticity of the spring spring 63. In other words, the diagonal material H absorbs the vibration of the ground 9 such as an earthquake. When the vibration ends, the piston 62 returns to the original position by the elasticity of the spring spring 63.
Since the roof panel 3 is substantially the same as a conventional folded roof, the description thereof is omitted.

Next, the construction method of this building U and the effect | action of the building U are demonstrated.
The vertical member 12 and the horizontal member 13 to which the base diagonal member 5 is attached are manufactured in advance, and a hole is formed in the ground at the construction site. The tip of the vertical member 13 is inserted into this hole, and concrete is driven into the foundation 11. And if the vertical member 13 is fixed with this foundation 11, the foundation part 1 will be completed.
The building unit 2 and the roof panel 3 are manufactured at the factory.
And this building unit 2 and the roof panel 3 are conveyed to a construction site.

At the construction site, the building unit 2 is installed in advance on the cross member 13 and the vertical member 12 of the foundation 1 provided in advance to form the first floor, and the building unit 2 is formed on the building unit 2 on the first floor. Is installed to form the second floor, and the roof panel 3 is mounted on the building unit 2 on the second floor.
In addition, when various finishing is performed, the building U is completed.

  In the building U thus completed, the base portion 1 is provided with a substantially vertical vertical member 12 made of steel, and a substantially horizontal cross member 13 is provided above the vertical member 12. 12 is reinforced with a base diagonal member 5 which is a wand that is passed from the vertical member 12 to the horizontal member 13 in an oblique direction. Therefore, when the ground 9 shakes due to an earthquake or the like, it has a damping structure. The base diagonal member 5 absorbs the shaking of the ground, and the shaking of the cross member 13 which is a cross beam is reduced.

  In general, the building unit 2 on the second floor is more likely to swing than the building unit 2 on the first floor, but the building unit 2 of the first embodiment is provided with a substantially vertical column 21, and this column 21 is a column. 21 is reinforced with diagonal members 4 in the building that are passed diagonally from the ceiling beam 23, and the diagonal members 4 in the building have a vibration-damping structure, so even if the building unit 2 on the first floor is shaken The diagonal member 4 in the vibration-damping structure building provided between the first-floor column 21 and the ceiling beam 23 absorbs the shaking of the first-floor building unit 2, and as a result, the second-floor building unit 2 is conventional. The vibration becomes smaller.

Since it is in this way, the entire building U including the building unit 2 on the first floor is difficult to shake, and is a building with good habitability.
When the vibration such as an earthquake ends, the building unit 2 returns to a predetermined position due to the elasticity of the elastic body, and the building U is not distorted.

Further, the base diagonal member 5a is inserted and attached to the vertical member 12a and the floor beam 22a of the first floor building unit 2a to complete the foundation portion 1, or the pillar 21a of the first floor building unit 2a and the floor beam 22a of the second floor The diagonal member 4a in the building is passed over and attached, or the diagonal member 4a in the building is passed over and attached to the pillar 21a of the building unit 2a on the second floor and the roof beam (not shown) of the roof unit 3a.
Since the operation of the diagonal members 4a and 5a is substantially the same as that of the first embodiment, the description thereof is omitted.
In addition, when various finishing is performed, the building Ua is completed.

  In the building Ua thus completed, the base portion 1 is provided with a vertical vertical member 12a made of steel, and the floor beam 22a of the first floor building unit 2a is provided above the vertical member 12a. Further, since it is reinforced by the foundation diagonal material 5a passed diagonally from the vertical member 12a to the floor beam 22a, when the ground 9a shakes due to an earthquake or the like, the foundation diagonal material 5a having a vibration-damping structure is provided. Absorbs the shaking of the ground 9a, and the shaking of the floor beam 22a of the building unit 2a on the first floor is reduced.

In addition, the building unit 2a on the second floor is more likely to shake than the building unit 2a on the first floor. However, in the second embodiment, the building unit 2a is provided with a plurality of substantially vertical columns 21a. 21a is reinforced with diagonal members 4a in the building that are obliquely passed from the column 21a to the ceiling beam 22a. The diagonal material 4a in the interior absorbs the shaking of the building unit 2a on the first floor, and the building unit 2a on the second floor has less vibration than the conventional second floor.
Therefore, the entire building Ua including the building unit 2 on the first floor has a small shaking and is a comfortable building.
When the vibration such as an earthquake ends, the building unit 2a returns to a predetermined position due to the elasticity of the elastic body, and the building Ua after the vibration such as an earthquake does not distort.
