【発明の属する技術分野】
本発明は、これから住宅を建設しようとする人が、自分の敷地の地盤について、充分な認識を持つことができ、不安定な地盤に対して充分の地盤安定化措置を講じることが出来るようにする模型により構成した住宅地盤の影響体験装置に関する。
【0002】
【従来の技術】
従来は、住宅を建設する場合において、地盤の状況や、不安定な地盤に対する補強措置等については、建築会社が独自に検討し、建設予定者に伝えて了解を得た上で、地盤の補強工事をするという手順が取られていた。
【0003】
【発明が解決しようとする課題】
従来の方法では、建設予定者にとっては自分の敷地の地盤の状態がどうであるのかを充分に知ることが出来ず、何の為にこのような補強作業が必要なのか理解出来ず、充分な地盤の補強措置を取ることを拒んだり、地盤の補強に要する費用に対して不信感を懐く結果となっていたのである。
本発明は、このような従来の不具合を解消する為に、支持地盤と表層地盤の状況の相違により、地盤を補強しない場合には、将来どのような不具合が発生するかを目で確かめることが出来るようにしたものである。
【0004】
【課題を解決するための手段】
本発明が解決しようとする課題は以上の如くであり、次に該課題を解決するための手段を説明する。
請求項1においては、剛性材により構成した支持地盤Bの上に表層地盤Aを載置し、該表層地盤Aは、住宅模型Hを載置した後に時間の経過と共に、徐々に表面が押されて変形沈下していく多孔性材料により構成し、前記支持地盤Bは、表層面から浅い位置にある支持地盤B1と、表層面に対して傾斜した支持地盤B2と、表層面から深い位置にある支持地盤B3により構成し、前記表層地盤Aの表面に、重錘により構成した住宅模型Hを載置すべく構成したものである。
【0005】
請求項1においては、請求項1記載の住宅地盤の影響体験装置において、表層面から浅い位置にある支持地盤B1と表層面に対して傾斜した支持地盤B2の部分に基礎杭Cを打ち込み可能な構成としたものである。
【0006】
請求項3においては、請求項1記載の住宅地盤の影響体験装置において、表層地盤Aの部分の一部を、表層地盤Aを固形化して地盤の支持力を向上させた表層改良地盤Dに変更して配置可能としたものである。
【0007】
【発明の実施の形態】
次に本発明の実施の形態を説明する。
図1は本発明の住宅地盤の影響体験装置の表層地盤Aと支持地盤Bの部分を示す斜視図、図2は該住宅地盤の影響体験装置に載置する重錘により構成した住宅模型Hの斜視図、図3は同じく住宅地盤の影響体験装置に載置する基礎模型Kの斜視図、図4は基礎杭Cを打ち込んだ状態の住宅地盤の影響体験装置の正面図、図5は基礎杭Cの上に住宅模型Hを載置した状態の前方斜視図、図6は同じく後方斜視図、図7は傾斜した支持地盤B2と深い支持地盤B3の構成の異なる住宅地盤の影響体験装置の斜視図、図8は同じく斜視図、図9は支持地盤Bの相違により基礎模型Kが変化する状態を示す図面、図10は支持地盤Bの相違による住宅模型Hの状態の変化を示す図面である。
【0008】
本発明の住宅地盤の影響体験装置は、住宅建設会社の展示場や商談場所等に配置するものである。そして、住宅を建設しようとする施工主から、所有する敷地に関する情報を入手して、この敷地の住所や番地等を聞き取ることにより、各地方自治体毎に保有している都市計画地図や、アボイドマップと呼ばれる、過去の被害区域地図や、崖崩れ発生箇所表示地図や、急傾斜地崩壊危険区域地図や、法指定危険区域地図等から、その敷地の地盤状況を推定し、本発明の住宅地盤の影響体験装置により、適切な地盤の補強工事を行う必要があることを知らせるのである。
【0009】
図1と図2と図3において、住宅地盤の影響体験装置の全体的な構成を説明する。
支持地盤Bは剛性の材料により構成している。そして、該支持地盤B自体は変形をしないのである。該支持地盤Bは、浅い支持地盤B1と傾斜した支持地盤B2と深い支持地盤B3の三つにより構成している。そして、該支持地盤Bの上に、変形可能な合成樹脂材料により形成した表層地盤Aを載置するように構成している。該表層地盤Aは、やや固めのスポンジ材料等により形成しており、傾斜地用軟質地盤A1、平地用軟質地盤A2及び平地用硬質地盤A3により構成している。前記表層地盤Aを形成するやや固めのスポンジ材料は、通常のスポンジ材料の如く、住宅模型Hを載置すると直ぐにそのまま押し込まれるような多孔性材料ではなくて、住宅模型Hを載置した後に、時間の経過と共に徐々に表面が押されて変形沈下していく独特の多孔性材料により構成し、地盤状況を表現可能なものとしている。
【0010】
このように、多孔性材料により形成した表層地盤Aの変形が徐々に進むことにより、住宅の建設後に年数の経過と共に、徐々に地盤の変化が発生して、住宅が傾いて行く様を観察できるように構成しているのである。また、前記支持地盤Bの上には、表層改良地盤Dの部分と、なにも改良を施していない表層地盤Aの部分を表現できるように構成しているのである。
前記表層改良地盤Dの部分は、土壌改良材等を注入して、表層地盤Aを固形化して地盤の支持力を向上させたことを表現可能としたものであり、何の改良も施さない場合よりも、支持力が大であり、地盤の沈下や、住宅の傾斜の発生が少ないことがわかるように構成しているのである。
【0011】
図2に示した住宅模型Hは、鉛等の重錘により構成しており、表層地盤Aの変形が発生しやすく、これを観察し易いように構成している。また、住宅模型Hの底面は平面ではなくて、基礎に該当する突起が四隅に突出されており、該突起の部分により住宅模型Hの重量を受けるので、この突起の下部に該当する表層地盤Aには面積当たりの支持重量が大きくなり、変形が発生しやすい構造となっている。また、四本の突起とすることにより、図10に示す如く、それぞれの該当する部分の地盤支持力の相違によって、住宅模型Hの傾斜状態が異なって発生することがわかりやすいように構成している。
【0012】
また、図3に示す如く、住宅の基礎部分の基礎模型Kも用意しており、この基礎模型Kを表層地盤Aの上に載置することによっても、地盤の支持力の相違が理解できるように構成している。
【0013】
図4においては、住宅地盤の影響体験装置の傾斜した支持地盤B2の部分に基礎杭Cを打ち込んで状態を示している。該傾斜した支持地盤B2の部分に地盤補強工事をしない場合には、支持地盤Bの影響がそのまま出てくるので、住宅模型Hは徐々に斜めに傾斜した状態となるのであるが、基礎杭Cを基礎の下から、支持地盤Bに至る長さに打ち込むことにより、住宅模型Hの重量は基礎杭Cにより支持地盤Bに伝達支持されるので、地盤沈下が発生しないのである。この地盤沈下の発生しない状態が、図5と図6に図示されている。
【0014】
図7と図8においては、支持地盤Bの構成の相違する住宅地盤の影響体験装置の他の実施例が図示されている。
この場合には、傾斜した支持地盤B2の部分が2か所に構成されており、深い支持地盤B3が谷のように構成されている。この深い支持地盤B3の部分に向かって、住宅が傾斜する溺れ谷の状況の発生を表現可能としているのである。該溺れ谷の部分の地盤を補強する為に、基礎杭Cを打ち込んでおり、また表層改良地盤Dの部分が深い支持地盤B3の上方に配置されており、これらによって、住宅模型Hの傾斜や沈下を阻止することがわかる構成としている。
【0015】
図9においては、支持地盤Bの相違により、基礎模型Kがどのように沈下・傾斜するかが図示されている。また図10においては、支持地盤Bの相違により、住宅模型Hがどのように沈下・傾斜するかが図示されている。表層改良地盤Dの場合には、地盤沈下は発生しない。表層改良を施していない場合において、浅い支持地盤B1の場合には、等沈下が発生する。また支持地盤Bが傾斜した支持地盤B2の場合には、不同沈下状態が発生し、これは非常に危険な状況である。このように不同沈下が発生する傾斜した支持地盤B2においては、基礎杭Cの打ち込みが必要であることがわかる。
【0016】
【発明の効果】
本発明は以上の如く構成したので、次のような効果を奏するのである。
請求項1の如く、剛性材により構成した支持地盤Bの模型の上に、表層地盤Aの模型を載置し、該表層地盤Aの模型は、住宅模型Hを載置した後に時間の経過と共に、徐々に表面が押されて変形沈下していく多孔性材料により構成し、前記支持地盤Bの模型は、表層面から浅い位置にある支持地盤B1と、表層面に対して傾斜した支持地盤B2と、表層面から深い位置にある支持地盤B3により構成し、前記表層地盤Aの模型の表面に、重錘により構成した住宅模型Hを載置すべく構成したので、支持地盤Bの状態の相違により、表層地盤Aの上に建設した住宅が将来どのような影響を受けるかを、目で見て知ることが出来るとともに、将来において不具合が発生しないように、どのような地盤の補強工事をする必要があるのかを知ることが可能となるのである。
【0017】
請求項2の如く、表層面から浅い位置にある支持地盤B1と表層面に対して傾斜した支持地盤B2の部分に模型の基礎杭Cを打ち込み可能な構成としたので、基礎杭Cによる補強の効果を、明白に知ることが可能となり、住宅を建設するにあたり施工主と建設会社との同意の下で基礎杭の打ち込みが出来、充分な地盤の補強効果を得ることが出来るのである。
【0018】
請求項3の如く、表層地盤Aの模型の一部を、表層地盤Aの模型を固形化して地盤の支持力を向上させた表層改良地盤Dの模型に変更して配置可能としたので、表層改良地盤Dの効果を知ることができ、基礎杭Cによる補強ほどではないが、住宅を建設するにあたり表層改良地盤D程度の補強をすれば、充分な地盤支持力を得られる地域では、基礎杭に替えて表層改良地盤とすることが可能となったのである。

It is related with the influence experience apparatus of the residential ground comprised by the model to do.
[0002]
[Prior art]
Conventionally, when constructing a house, the construction company independently examines the ground conditions and measures to reinforce unstable ground. The procedure of construction was taken.
[0003]
[Problems to be solved by the invention]
In the conventional method, it is not enough for the prospective construction person to know how the ground condition of his / her site is, and it is not enough to understand why such reinforcement work is necessary. The result was that they refused to take ground reinforcement measures and were distrusted by the cost of ground reinforcement.
In order to eliminate such a conventional problem, the present invention can visually confirm what kind of problem will occur in the future if the ground is not reinforced due to the difference in the situation of the support ground and the surface ground. It is something that can be done.

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described.

[0008]
The residential ground influence experience apparatus of the present invention is arranged in an exhibition hall or a business meeting place of a housing construction company. And by obtaining information about the site you own from the contractor who wants to build a house and listening to the address, address, etc. of this site, you can obtain city planning maps and void maps that are owned by each local government. Estimate the ground condition of the site from past damage area map, landslide occurrence map, steep slope collapse risk area map, legally specified risk area map, etc. The experience device informs you that it is necessary to perform appropriate ground reinforcement work.
[0009]
The overall configuration of the residential ground influence experience apparatus will be described with reference to FIGS.
The supporting ground B is made of a rigid material. And this support ground B itself does not deform | transform. The support ground B is composed of a shallow support ground B1, an inclined support ground B2, and a deep support ground B3. And it is comprised so that the surface layer ground A formed with the synthetic resin material which can deform | transform on this support ground B is mounted. The surface layer ground A is formed of a slightly hard sponge material or the like, and is composed of a sloping ground soft ground A1, a flat ground soft ground A2, and a flat ground hard ground A3. The slightly hard sponge material that forms the surface ground A is not a porous material that is pushed in as it is when the house model H is placed, like a normal sponge material, but after the house model H is placed, It is made of a unique porous material that gradually deforms and sinks as the surface is gradually pushed over time, making it possible to express the ground conditions.
[0010]
In this way, the deformation of the surface layer ground A formed of the porous material gradually progresses, so that it can be observed that the ground gradually changes with the passage of years after the construction of the house and the house is tilted. It is configured as follows. Moreover, on the said support ground B, it has comprised so that the part of the surface layer improved ground D and the part of the surface layer ground A which has not performed any improvement can be expressed.
The surface improvement ground D part is a case where it is possible to express that a soil improvement material or the like is injected to solidify the surface ground A to improve the supporting capacity of the ground, and no improvement is made. It is constructed so that it can be seen that the bearing capacity is greater and the occurrence of ground subsidence and housing inclination is less.
[0011]
The housing model H shown in FIG. 2 is composed of a weight such as lead, and the surface layer ground A is easily deformed and is easily observed. In addition, the bottom surface of the housing model H is not a flat surface, and protrusions corresponding to the foundation protrude from the four corners, and the portion of the protrusion receives the weight of the housing model H. Therefore, the surface ground A corresponding to the lower part of the protrusions The structure has a structure in which the supporting weight per area increases and deformation is likely to occur. Further, by using four protrusions, as shown in FIG. 10, it is easy to understand that the inclined state of the house model H is generated differently due to the difference in ground supporting force of each corresponding part. .
[0012]
In addition, as shown in FIG. 3, a basic model K for the foundation portion of the house is also prepared. By placing this basic model K on the surface ground A, the difference in the supporting force of the ground can be understood. It is configured.
[0013]
FIG. 4 shows a state in which the foundation pile C is driven into the inclined support ground B2 portion of the residential ground influence experience device. When ground reinforcement work is not performed on the inclined support ground B2, the influence of the support ground B comes out as it is, so the house model H is gradually inclined obliquely, but the foundation pile C Since the weight of the house model H is transmitted and supported by the foundation pile C to the support ground B by driving it into the length from the bottom of the foundation to the support ground B, ground subsidence does not occur. The state where the ground subsidence does not occur is shown in FIGS. 5 and 6.
[0014]
FIGS. 7 and 8 show another embodiment of the residential ground influence experience apparatus in which the structure of the supporting ground B is different.
In this case, the inclined support ground B2 is configured in two places, and the deep support ground B3 is configured like a valley. It is possible to express the occurrence of the situation of the drowning valley where the house is inclined toward the deep support ground B3. In order to reinforce the ground in the drenched valley, the foundation pile C is driven in, and the surface improved ground D is located above the deep support ground B3. It is configured to prevent this.
[0015]
FIG. 9 shows how the basic model K sinks and tilts due to the difference in the supporting ground B. Further, FIG. 10 illustrates how the house model H sinks and tilts due to the difference in the supporting ground B. In the case of the surface improvement ground D, ground subsidence does not occur. In the case where the surface layer is not improved, the subsidence occurs in the case of the shallow support ground B1. Further, in the case of the support ground B2 in which the support ground B is inclined, a non-uniform subsidence state occurs, which is a very dangerous situation. Thus, it can be seen that the foundation pile C must be driven in the inclined support ground B2 where the uneven settlement occurs.
[0016]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
The model of the surface layer ground A is placed on the model of the support ground B made of a rigid material as in claim 1, and the model of the surface layer ground A is placed over time after the housing model H is placed. The model of the support ground B includes a support ground B1 that is shallow from the surface and a support ground B2 that is inclined with respect to the surface. And the support ground B3 located deep from the surface, and the housing model H composed of weights is placed on the surface of the surface ground A model. As a result, it will be possible to see visually how the house built on the surface layer A will be affected in the future, and what kind of ground reinforcement work will be done so that no problems will occur in the future. Knowing what you need It is become Noh.
[0017]
As in claim 2, since the model foundation pile C can be driven into the support ground B1 that is shallow from the surface and the support ground B2 that is inclined with respect to the surface, the reinforcement by the foundation pile C It becomes possible to know the effect clearly, and in constructing a house, the foundation pile can be driven in with the agreement of the construction company and the construction company, and a sufficient ground reinforcement effect can be obtained.
[0018]
Since a part of the model of the surface layer ground A is changed to the model of the surface layer improved ground D in which the surface layer ground A model is solidified to improve the supporting force of the ground as in claim 3, the surface layer In the area where you can know the effect of the improved ground D, and not as much as the reinforcement by the foundation pile C, but you can obtain sufficient ground bearing capacity if you reinforce the surface improved ground D when constructing a house, It became possible to make the surface improved ground instead of.
