On the foundation are pillars 8a l -8a r , 8b l -8b r , 8c l -
8c r (on Figure 1, the left side base in Figure 1a is represented by suffix l, and the right side base is represented by suffix r). And beams 6a, 6b, 6 that cross the upper side of the existing building 2
c is rigidly connected between columns 8a l -8a r , 8b l -8b r , 8c l -8c r , and building 4 is placed on beams 6a, 6b, 6c.
was building. Therefore, the beams 6a, 6b, 6c are
The span becomes longer, a large bending moment acts on the column 8a l −, which is rigidly connected to the beams 6a, 6b, and 6c.
A large bending moment also acts on columns 8a r , 8b l -8b r , 8c l -8c r , and columns 8a l -8a r , 8b l -8b r , 8c l
-8c r leg 9a l -9a r ,9b l -9b r ,9c l -9c r
and basic 12a l −12a r , 12b l −12b r , 12c l −
At 12c r , the building 4 rotates within the vertical plane in the direction of straddling the existing building 2 and moves horizontally within that plane, causing distortion and cracks in the building.

Legs 9a l -9a r , 9b l -9b r , 9c l -9c r or foundations 12a l -12a r , 12b l -12b r , 12c l -12
In some cases, underground beams 14a, 14b, and 14c were provided to connect the columns 8 to each other to prevent the legs 9 of the columns 8 and the foundations 12 from rotating or moving in the horizontal direction.
また、柱８al−８ar，８bl−８br，８cl−８crや
梁６ａ，６ｂ，６ｃの断面積を大きくし剛性を高
めてこれらに対処する場合もあつた。 In addition, there were cases in which the cross-sectional areas of the columns 8a l -8a r , 8b l -8b r , 8c l -8c r and the beams 6a, 6b, 6c were increased to increase their rigidity to cope with these problems.
しかしこれらはいずれも構造コストを大幅に高

礎部分が、アースアンカー方向に拘束される。<<Effect>> Because the earth anchor was driven diagonally downward into the ground from the column base or the foundation built under the column base, the column base or the foundation built under the column base was damaged. , constrained in the direction of the earth anchor.
《実施例》
以下、本考案の好適な一実施例を第１図に基づ

地中３には、既設建築物２の両側の、建物４が
既設建築物２を跨ぐ方向の鉛直面内、所定位置に
杭１０al−１０ar，１０bl−１０br，１０cl−１０
crが鉛直に所定深さまで計６本打込まれている。 Piles 10a l -10a r , 10b l -10b r , 10c l -10 are installed in the underground 3 at predetermined positions on both sides of the existing building 2 in the vertical plane in the direction in which the building 4 straddles the existing building 2 .
A total of six crs are driven vertically to the specified depth.

アースアンカーが打込まれている。なお、第１図
ｂは、手前側に打込まれたアースアンカーのみを
示している。 And the piles 10a l -10a r , 10b l -10b r ,
Foundation 12a l -12a r , 12b l on top of 10c l -10c r
-12b r , 12c l -12c r are constructed, but in this example, the bases 12a l -12a r , 12b l -12b r ,
From the top end of 12c l -12c r , place the earth anchor 16 diagonally downward in the ground on the opposite side of the end.
a l -16a r , 16b l -16b r , 16c l -16c r are installed by driving. The driving direction is the direction in which the building 4 straddles the existing building 2, and driving can be done in any direction (see Figure 1,
In Figure A, the earth anchor driven diagonally downward to the left is represented by suffix...1, and the earth anchor driven diagonally downward to the right is represented by suffix 2). Three earth anchors are driven in one direction from one foundation. Note that FIG. 1b only shows the earth anchor driven into the front side.
アースアンカー１６は、例えば、高杭張力鋼１
８と固結性薬剤等の注入によりその先端に形成し
た塊状物２０とにより形成され、高杭張力鋼１８
の上端は、例えば、打込み角度に応じて製作され
た台座およびボルト等を介して基礎１２に緊締固
定される。 The earth anchor 16 is made of, for example, high pile tensile strength steel 1
8 and a lump 20 formed at the tip by injecting a caking agent or the like, and the high pile tensile strength steel 18
The upper end of is tightened and fixed to the base 12 via, for example, a pedestal and bolts manufactured according to the driving angle.
アースアンカー１６の打込み角度は、基礎１２
に生じる回転や水平方向の移動を最も効率よく防
ぎ得る角度に適宜、設計される。 The driving angle of the earth anchor 16 is the foundation 12.
The angle is appropriately designed to most efficiently prevent rotation and horizontal movement that may occur.
基礎１２の上には柱８が建てられ、柱８には既
設建築物２の上側を横断する梁６が渡設され、梁
６の上に建物４が構築される。 A pillar 8 is built on the foundation 12, a beam 6 that crosses the upper side of the existing building 2 is installed on the pillar 8, and a building 4 is built on the beam 6.
基礎１２の上面の建物４が既設建築物２を跨ぐ
方向の端部から端部側とは反対側の地中の斜め下
方に向けて打込まれたアースアンカー１６によ
り、基礎１２がアースアンカー１６方向に拘束さ

束されているため、従来のように地中梁を設けた
り柱や梁の断面積を大きくすることなく、柱８の
脚部や基礎１２は拘束面内における回転や水平方
向の移動が防止される。 The foundation 12 is connected to the earth anchor 16 by the earth anchor 16 driven diagonally downward into the ground on the opposite side of the end from the end in the direction in which the building 4 straddles the existing building 2 on the upper surface of the foundation 12. On the other hand, since the foundation 12 is restrained in the vertical upward direction by the piles 10, the legs of the columns 8 and the The foundation 12 is prevented from rotating or moving in the horizontal direction within the constraint plane.
従つて、既設建築物を跨ぐ建物を構築する際に
地中梁を設ける場合は、建物の近傍に縦穴を掘
り、この縦穴内から横穴を掘るといつた極めて面
倒な作業を行う必要があつたものを省略すること
ができる。 Therefore, when installing underground beams when constructing a building that straddles an existing building, it was necessary to perform extremely troublesome work such as digging a vertical hole near the building and then digging a horizontal hole from within this vertical hole. You can omit things.
本考案では、基礎１２にアースアンカー１６を
配設したが、アースアンカー１６は柱８の脚部に
配設してもよく、また杭１０の上部に配設しても
よい。 In the present invention, the earth anchor 16 is provided on the foundation 12, but the earth anchor 16 may be provided on the leg of the column 8 or on the top of the pile 10.
また本実施例では杭１０の上に基礎１２を設け
たが、地盤が強固である場合等に、杭を設けず直
接基礎を設けその上に柱を建てる場合、杭や基礎
を設けず直接柱脚がピン状に形成された柱を設け
る場合等にも、本考案は適用される。 Furthermore, in this embodiment, the foundation 12 was provided on the piles 10, but in cases where the ground is strong, etc., if a foundation is directly installed without providing piles and a pillar is erected on top of the foundation, it is possible to directly support the foundation without providing piles or foundations. The present invention is also applicable to cases where a column having pin-shaped legs is provided.
また本実施例では１つの基礎から１つの向きに
３本のアースアンカーを打込んだが、打込個数は
何ら制約されるものではなく、また各基礎ごとに
打込個数を変えても差し支えない。 Further, in this embodiment, three earth anchors were driven in one direction from one foundation, but the number of anchors to be driven is not restricted in any way, and the number of anchors to be driven may be changed for each foundation.

分な建物の基部構造を得ることができる。《Effect of the idea》 From the pillar base of the building that stands on both sides of the existing building, or the foundation built under the pillar base, diagonally downward into the ground in the direction in which the building straddles the existing building. The ground anchor driven in by the ground anchor prevents the column base or the foundation built under the column base from rotating or moving, and prevents distortion and cracks in the building. By inexpensive means it is possible to obtain a building base structure sufficient to support a building that straddles an existing building.
