Description

本発明は、建物の防振構造に関する。   The present invention relates to a vibration isolating structure for a building.

従来、地震等の地面の揺れに対して建物を護るための種々な建物の防振構造が知られている。
例えば、特許文献1〜特許文献3には、建物の基礎部を制振構造にして建物を地震等の振動から護る構造が記載され知られている。
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.

この特許文献1〜3に記載されている構造は、地盤に形成された上面が平坦な地盤側基礎と、建物本体の下面に形成された下面が平坦な住宅側基礎とからなり、地盤側基礎の上で住宅側基礎を摺動自在又は転がる水平移動可能な状態にして、建物本体が住宅側基礎の上に据え付けられた防振構造である。   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.

又、特許文献4や特許文献5には、建物の柱から天井梁又は上階の床梁に斜め方向に差し渡した方杖(特許文献4)やブレース(特許文献5)等の斜材で、柱を補強する構造であって、この斜材を制振構造にして建物を護る防振構造が記載されている。尚、この制振構造は、柱や梁と、方杖やブレースのいずれか一方に設けられた長孔と他方に設けられた丸孔とに通されたボルトと、このボルトに螺入されたナットで、方杖やブレースを柱や梁に取り付けた構造をしている。   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. In addition, this vibration control structure was screwed into a bolt passed through a pillar or a beam, a long hole provided in one of the cane or brace, and a round hole provided in the other. It has a structure in which a cane or brace is attached to a pillar or beam with a nut.

又、特許文献6には、柱や梁等の架構本体とブレースや壁等の可変剛性要素との間、又は、可変剛性要素同士を、シリンダーと、このシリンダー内を往復するピストンと、このピストンの両側の油圧室とからなるピストン構造で連結し、この油圧室内に入っている油の量をコンピュータで制御して地震等による振動を吸収しようとする防振構造が記載されている。   Patent Document 6 discloses that a cylinder, a piston that reciprocates in the cylinder, a piston that reciprocates between the variable rigidity elements such as a column or a beam and a variable rigidity element such as a brace or a wall, and the piston. There is described a vibration isolation structure that is connected by a piston structure composed of hydraulic chambers on both sides of the cylinder and that controls the amount of oil contained in the hydraulic chamber by a computer to absorb vibrations caused by earthquakes and the like.

しかし、上記特許文献1〜3に記載されている構造では、地震等で地盤が揺れると、地盤側基礎が揺れる。すると、建物本体がそのままの位置を保つように、この揺れる地盤側基礎の上を住宅側基礎が建物本体と共に、左右に水平移動して、建物本体の揺れを小さくするものである。即ち、この地盤に形成された地盤側基礎と建物本体の位置が相対的に水平移動することによって建物本体を地震等の振動から護る構造になっているのである。   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.

このことを図10を参照しながら説明する。
図10において、100は地盤であり、この地盤100には上面が略平坦な地盤側基礎200が設けられている。
300は建物本体であり、この建物本体300の下面には略平坦な住宅側基礎400が設けられている。
そして、図10の実線で示すように、この地盤側基礎200の上に住宅側基礎400を水平方向に移動可能に載せて、地盤100の上に建物本体300が据え付けられている。
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.

地震等で地盤100が揺れると、建物本体300の位置が地盤100に対して、図10の点線で示すように、相対的に水平移動し、矢印で示すように振動する。
この際、隣に地震と共に振動する建物や木等の固定物450があると、建物本体300が隣の建物や木等の固定物450にぶつかる危険がある。
従って、この建物本体300の水平移動で隣接する建物や木等の固定物450にぶつからないようにするためには、建物本体300と隣接する建物や木等の固定物450と間の距離を大きくする必要があり不便である。
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.

又、建物本体300の中に設置された設備に連結する配管のように、地盤100と建物本体300とを連結する部材は、建物本体300と地盤100の相対的な水平移動によって破壊されることがあるので、この部材を建物本体300と地盤100の相対的な移動に追随できる構造にする必要があり、配管等の費用が高くなるという問題がある。   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.

又、特許文献4や特許文献5に記載されている構造は、建物の柱から天井梁又は上階の床梁に、方杖(特許文献4)やブレース(特許文献5)を差し渡して柱や梁を補強すると同時に、この方杖やブレースを制振構造にして地震等の振動から建物本体を護る構造にしているが、この構造と作用と問題点について、図11を参照しながら説明する。   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.

図11において、500は地盤である。そして、この地盤500の上に基礎600を設け、この基礎の上に2階建ての建物700が据え付けられている。
この建物700には柱710から天井梁、上階の床梁、屋根の屋根梁等の横材720に斜め方向に差し渡した方杖800で、柱710や横材720を補強している。
そして、図11(ロ)に示すように、この方杖800と、柱710や横材720の連結構造は、柱710や横材720に設けられた丸孔750と、方杖800に設けられた長孔850に通されたボルト900とこのボルト900に螺入されたナット910で連結している。
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.

このような構造になっているので、地震等の大きな力によって地盤500が振動すると、柱710が傾くように振動し、柱710は横材720の角度が変化し、この変化によって方杖800の長さが変わるが、ボルト900が長孔850の中を移動して、この長さを変化させる力を吸収し、矢印に示す天井梁や上階の床梁720の揺れが小さくなる。   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.

このような構造になっているので、この天井梁や上階の床梁730より上の上階の振動は小さくなり極めて便利であるが、1階の床梁は地盤500と共に振動するので、主に人が生活している1階の振動は小さくならない。
又、地震等の振動でボルト900が長孔850に沿って移動した状態で地震等の振動が停止すると、元の状態に戻らず、建物が変形した状態になったままになり建物に歪みが残る。
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.

又、特許文献6に記載されている構造では、油圧室内に入れられている油の量をコンピュータで制御して振動を吸収しようとするので、大規模な制御装置が必要であり、設備費が高くなるという問題がある。
そこで、本発明の目的は、地盤側基礎上を建物本体が水平移動しなくとも、1階の建物を含めた建物全体の振動を小さくすることのできる安価な建物の防振構造を提供することである。
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.

本発明における基礎部とは、地盤に設けられ、この上に建物本体が建てられるものであって、布型の基礎であってもよいし束型の基礎であってもよい。
そして、従来の多くの基礎部がコンクリート製であるが、本発明の基礎部は鉄骨製であることが従来の基礎部と大きく異なる。
本発明における斜材には、基礎部に設けられている基礎の斜材と建物の中に設けられている建物内の斜材の2種類ある。
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.

そして、基礎の斜材は、縦材から横材又は隣の縦材に斜め方向に差し渡す梁材であって、方杖やブレース等が好適な斜材である。
又、建物内の斜材は、柱から、天井梁、上階の床梁、屋根の屋根梁のいずれかである横材又は隣の柱に斜め方向に差し渡す梁材であって、方杖やブレース等が好適な斜材である。

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.

請求項1記載の発明における建物とは、種々な形式の建物のすべてを含む。例えば、現場で建てる現場施工の建物であってもよいし、工場で建物ユニットを製造し、現場では、この建物ユニットを組み立てるユニット建物とか組立住宅とかいわれている建物であってもよい。又、このユニット建物でも、鉄骨系のユニット建物であってもよいし、木造系のユニット建物であってもよい。
特に、請求項2記載及び請求項3記載のような建物ユニットを組み立てた建物が好適である。
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.

請求項1記載の発明や請求項3記載の発明における制振構造とは、振動を吸収する構造をいい、前記特許文献2に記載されている制振構造であってもよいし、斜材を第一斜材と第二斜材とに分割し、この間にゴム板や積層ゴム等の弾性体を取り付けたものでもよいが、請求項4記載のように、第一斜材と第二斜め材の間にダンパーを挟んだ制振構造が好ましい。   The damping structure in the invention described in claim 1 or the invention described in claim 3 refers to a structure that absorbs vibration, may be the damping structure described in Patent Document 2, or The first diagonal member and the second diagonal member may be divided into a first diagonal member and a second diagonal member, and an elastic body such as a rubber plate or laminated rubber may be attached between them. A vibration damping structure in which a damper is sandwiched between them is preferable.

請求項3記載の発明に記載されている天井梁、上階の床梁、屋根の屋根梁である横材とは、天井梁と床梁や屋根梁とが別の梁となっている建物では天井梁をいい、天井梁と上階の床梁とが同じものであって、床梁と称している建物では、この上階の床梁をいい、最上階の天井梁と屋根梁とが同じであって屋根梁と称している建物では屋根梁をいう。   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.

(作用)
請求項1記載の発明では、建物本体が基礎部の上に建てられた建物の防振構造であって、前記基礎部には、鉄骨製の略垂直な縦材が設けられ、この縦材の上方には、縦材の先端から略水平方向に突設された横梁又は建物本体の1階の床梁である横材が設けられ、前記縦材は、縦材から横材又は隣の縦材に斜め方向に差し渡された振動を吸収する制振構造の斜材で補強されているので、次に示すように、1階の床梁が揺れ難く、その結果、建物全体が揺れ難いのである。
(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. .

即ち、地盤が揺れたときに、従来のコンクリート製の基礎部では、この基礎部が殆ど変形しないので、この振動が直接建物本体に伝わり、建物本体が地震と同じように揺れるが、この請求項1記載の発明では、基礎部の縦材が可撓性を有する鉄骨製であるので、この鉄骨製の縦材が横方向に撓む方向に振動し、縦材と横材の角度を変化させ、縦材から横材又は隣の縦材に斜め方向に差し渡された斜材の長さが変える振動となるが、この斜材は制振構造になっているので、この制振構造の斜材が振動を吸収して、横材の振動が小さくなる。   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.

このように、地盤が揺れても、制振構造になっている斜材が地盤の揺れを吸収して横梁又は建物本体の1階の床梁である横材の揺れが小さくなり、この横材又は建物の1階の床梁より上方にある建物本体、即ち、1階の部分を含めた建物本体全体の揺れが小さくなる。   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.

請求項2記載の発明では、請求項1記載の発明に係り、前記建物本体が複数個の建物ユニットを組み立てたユニット建物本体であるので、基礎部に斜材を取り付け、この上に工場で組み立てたユニット建物を据え付けるだけや、基礎部の上にユニット建物を据え付けた後に斜材を取り付けるだけで防振構造の建物とすることができ、極めて施工し易い。
特に、この建物ユニットが一般に揺れ易いといわれている鉄骨系の建物ユニットである場合には、揺れが小さくなり、好ましい建物となる。
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.

請求項3記載の発明では、請求項2記載の発明に係り、前記建物ユニットには、略垂直な柱が設けられ、この柱の上方には、天井梁、上階の床梁、屋根の屋根梁のいずれかである横材が設けられ、前記柱は、柱から横材又は隣の柱に斜め方向に差し渡された制振構造の斜材で補強されているので、前記請求項1記載の発明と同様に、1階の建物ユニットの揺れが小さいし、1階の建物ユニットが揺れても、1階の柱と天井梁又は上階の床梁との間に設けられた制振構造の建物内の斜材が1階の建物ユニットの揺れを吸収し、上階の建物ユニットの揺れが、従来より小さくなる。   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. 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.

このように、1階の建物ユニットを含めたユニット建物全体が揺れ難く、居住性のよい建物である。
請求項4記載の発明では、請求項1〜3のいずれかに記載のユニット建物の防振構造に係り、前記制振構造の斜材が、第一斜材とダンパーと第二斜材とをこの順に略一直線状に連結した棒状体であり、このダンパーは弾性体の弾性と粘稠な液体の粘性とを組み合わせた制振装置であるので、地震等の振動で縦材が振動し、斜材の長さが変化しようとする力が加わってもダンパーである防振装置の弾性体の弾性と粘稠な液体の粘性の組み合わせによる制振作用によって振動が大きく吸収され、建物が振動し難いし、振動が終了すると、弾性体の弾性により建物ユニットが所定位置に戻り、地震後の建物に歪みが発生しない。
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.

Glass wool insulation is attached to form the outer wall.

基礎部1は束型であって、図2に示すように、地盤9に埋め込まれたコンクリート製の基礎11と、この基礎11に立設された鉄骨製の断面コ字形長尺体の縦材12と、この縦材12の上端に略水平に取り付けられた鋼製の断面コ字形長尺体の横梁である横材13と、この縦材12と横材13とに斜め方向に差し渡された方杖である基礎の斜材5とからなる。
尚、この際の地盤9はベタ基礎であってもよい。
そして、この基礎部1の横材13の上に建物ユニット2が据え付けられている。
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.

建物内の斜材4と基礎の斜材5は略同じ構造であるので、この両方を示すときには、単に斜材Hと称する。
この斜材Hは、図4に示すように、第一斜材H1とダンパーである制振装置6と第二斜材H2とが略一直線状に連結されものである。
制振装置6は、円筒状で両側に蓋が取り付けられたシリンダー61と、このシリンダー61内を往復自在に取り付けられたピストン62と、このピストン62と両側の蓋との間に設けられたスプリングバネ63と、シリンダー61の中に封入された粘稠な液体64とからなり、シリンダー61とピストン62との間には小さな隙間65が設けられている。
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.

そして、このピストン62に取り付けられているピストンロッド65が第一斜材H1に連結され、シリンダー61の一方の蓋が第二斜材H2に連結されている。
そして、図2と図3に示すように、斜材Hが縦材12から横材13に、又は、柱21から天井梁23に、斜め方向に差し渡され、第一斜材H1と第二斜材H2の一方が縦材12や柱21に、又、他方が横材13や天井梁23に連結されている。
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.

この斜材Hの制振作用について説明する。
地震等で地盤9が振動すると、縦材12又は柱21が振動し、縦材12又は柱21と、横材13との角度が変化する振動となり、その結果、斜材Hの長さが変化する振動となる。
この振動を詳細に観察すると、先ず、地震等で地盤9が一方に移動すると、縦材12や柱21が撓んで傾き、この傾きによって、斜材Hの第一斜材H1と第二斜材H2の距離が変化し、ピストン62がシリンダー61内を移動するが、シリンダー61内には粘稠な液体64が封入されていて、この粘稠な液体64がシリンダー61とピストン62の間に設けられた小さな隙間65を通るだけしか移動しない。
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.

この際、粘稠な液体64が移動し始めるときに最も大きな力が必要で、移動し始めると段々速くなる。
しかし、このピストン62の両側に設けられているこのスプリングバネ63は、ピストン62が移動し始めるときには比較的小さい力でも移動するが、移動するに従って、この移動した距離に比例する力で元の状態に戻ろうとする。このように粘稠な液体64の粘性の抵抗力と、スプリングバネ63の弾性の抵抗力には時間差がある。
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.

このように移動するが、十分に移動が完了する前に、地震等の振動によって、縦材12や柱21が反対方向に移動し、ピストン62は反対方向に移動する。
このように粘稠な液体64の粘性と、スプリングバネ63の弾性によって生ずる時間差のある抵抗力によって振動が著しく小さくなる。換言すると、地震等の地盤9の振動を斜材Hが吸収する。そして、振動が終了すると、スプリングバネ63の弾性によりピストン62は元の位置に戻る。
屋根パネル3は従来の折版屋根と略同じであるので説明を省略する。
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.

次に、この建物Uの施工方法及び建物Uの作用について説明する。
予め、基礎の斜材5を取り付けた縦材12と横材13を製造し、施工現場で、地盤に穴を設け、この穴の中に縦材13の先端を差し込み、コンクリートを打ち込んで基礎11とし、この基礎11で縦材13を固定すると基礎部1が完成する。
工場で、建物ユニット2、屋根パネル3を製造する。
そして、この建物ユニット2、屋根パネル3を施工現場に運搬する。
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.

施工現場では、予め、設けられている基礎部1の横材13や縦材12の上に、建物ユニット2を据え付けて1階を形成し、この1階の建物ユニット2の上に建物ユニット2を据え付けて2階を形成し、この2階の建物ユニット2の上に屋根パネル3を取り付ける。
その他、種々な仕上げを行うと、建物Uが完成する。
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.

このようにして完成した建物Uでは、基礎部1には、鉄骨製の略垂直な縦材12が設けられ、この縦材12の上方には略水平な横材13が設けられ、この縦材12は、縦材12から横材13に斜め方向に差し渡された方杖である基礎の斜材5で補強されているので、地震等で地盤9が揺れると、制振構造になっている基礎の斜材5が地盤の揺れを吸収して横梁である横材13の揺れが少なくなる。   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.

又、通常、1階の建物ユニット2より2階の建物ユニット2の方が揺れ易いが、この実施例1の建物ユニット2には、略垂直な柱21が設けられ、この柱21は、柱21から天井梁23に斜め方向に差し渡された建物内の斜材4で補強され、この建物内の斜材4が制振構造になされているので、1階の建物ユニット2が揺れても、1階の柱21と天井梁23の間に設けられた制振構造の建物内の斜材4が1階の建物ユニット2の揺れを吸収し、その結果、2階の建物ユニット2が従来より振動が小さくなる。   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.

このようになっているので、1階の建物ユニット2を含めた建物U全体が揺れ難く、居住性のよい建物である。
又、地震等の振動が終了すると、弾性体の弾性により建物ユニット2が所定位置に戻り、建物Uに歪みが発生しない。
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.

The roof unit 3a is attached on the building unit 2a on the second floor.

又、縦材12aと1階建物ユニット2aの床梁22aに基礎の斜材5aを差し渡して取り付けて基礎部1を完成させたり、1階建物ユニット2aの柱21aと2階の床梁22aとに建物内の斜材4aを差し渡して取り付けたり、2階の建物ユニット2aの柱21aと屋根ユニット3aの図示しない屋根梁に建物内の斜材4aを差し渡して取り付ける。
尚、この斜材4a、5aの作用については、実施例1と略同じであるので、説明を省略する。
その他、種々な仕上げを行うと、建物Uaが完成する。
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.

このようにして完成した建物Uaでは、基礎部1には、鉄骨製の略垂直な縦材12aが設けられ、この縦材12aの上方には1階の建物ユニット2aの床梁22aが設けられ、この縦材12aから床梁22aに斜め方向に差し渡された基礎の斜材5aで補強されているので、地震等で地盤9aが揺れると、制振構造になっている基礎の斜材5aが地盤9aの揺れを吸収して1階の建物ユニット2aの床梁22aの揺れが小さくなる。   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.

又、通常、1階の建物ユニット2aより2階の建物ユニット2aの方が揺れ易いが、この実施例2では、建物ユニット2aは、略垂直な複数の柱21aが設けられ、この複数の柱21aは、柱21aから天井梁22aに斜め方向に差し渡された建物内の斜材4aで補強されているので、1階の柱21aと天井梁23aの間に設けられた制振構造の建物内の斜材4aによって1階の建物ユニット2aの揺れを吸収し、2階の建物ユニット2aが従来の2階より振動が小さい。
従って、1階の建物ユニット2を含めた建物Ua全体の揺れが小さく、居住性のよい建物である。
又、地震等の振動が終了すると、弾性体の弾性により建物ユニット2aが所定位置に戻り、地震等の振動が終了後の建物Uaに歪みが発生しない。
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.
