［発明の効果］
以上の説明から明らかなように、第１の発明に係る建築
物の基礎構造は、
■ 束と基板とが一体的に形成されているから、従来の
束石方式の基礎構造よりも、束下部の剛性が大である。[Effects of the Invention] As is clear from the above explanation, the foundation structure of the building according to the first invention is: ■ Since the bundle and the substrate are integrally formed, the foundation structure of the conventional bundle stone method is The lower part of the bundle has greater rigidity.
■ また、束下部の基板底面が凸になって、地盤の掘削
部分に入り込んでいるから基礎ずれかない。■ Also, the bottom of the board at the bottom of the bundle is convex and extends into the excavated area of the ground, so the foundation will not shift.
また、束下部の断面積が大になり、束より受ける垂直荷
重が分散して地盤へ伝達されるため、地盤の弱い所でも
基板が沈下するようなことがない。In addition, the cross-sectional area of the lower part of the bundle is large, and the vertical load received from the bundle is distributed and transmitted to the ground, so the board will not sink even in areas where the ground is weak.
■ また、基板の大きさを自由に選択できるから、基板
を大型にすることにより、束の垂直荷重の応力低下や転
倒に対する曲げモーメントの応力を低下させることがで
きる。(2) Furthermore, since the size of the board can be freely selected, by increasing the size of the board, it is possible to reduce the stress of the vertical load of the bundle and the stress of the bending moment against overturning.
また、第２の発明に係る建築物の基礎構造は、
■ 束下部の基板底面の凸部周囲の板状基板面を相互に
連続させて一体化しているから、束は大きな基板面から
立設した形になっているので、東同士が一体化した構造
になるから、独立束形の基礎よりも基板が大きくなり、
基板の剛性がより大になる。また、横方向からの力に対
しても独立形束基礎よりも安定である。In addition, the basic structure of the building according to the second invention is as follows: (1) Since the plate-shaped substrate surfaces around the convex portion of the bottom of the substrate at the bottom of the bundle are interconnected and integrated, the bundle can be erected from the large substrate surface. Since it has a structure in which the east sides are integrated, the base plate is larger than an independent bundle type foundation.
The rigidity of the board becomes greater. It is also more stable against lateral forces than independent bundle foundations.
さらにまた、束の垂直荷重の応力低下および転倒に対す
る曲げモーメントの応力が低下が図れる。Furthermore, the stress of the vertical load on the bundle and the stress of bending moment against overturning can be reduced.
■ また、束下部の基板底面にそれぞれ凸部が形成され
ているから、第１の発明同様基板がずれ難く安定である
。(2) Furthermore, since convex portions are formed on the bottom surfaces of the substrates at the bottom of the bundle, the substrates are stable and difficult to shift, similar to the first invention.
■ さらに、型枠を組んで基板を作る作業は、個々の独
立形束基礎を複数作る作業よりも効率的で容易である。■Furthermore, the work of assembling formwork to create a board is more efficient and easier than the work of creating multiple independent formwork foundations.
また、第３の発明に係る建築物の基礎構造は、０ 布基
礎の断面をＬ字形に形成し、かつこの布基礎の内側の基
板と束の基板とを一体化しているから、基礎が安定化し
、しかも従来の逆子字形布基礎の底部と異なり、建物の
外側へ突出している底板が省略できる。Further, in the foundation structure of the building according to the third invention, the cross section of the cloth foundation is formed into an L-shape, and the substrate inside the cloth foundation and the bundle of substrates are integrated, so that the foundation is stable. Moreover, unlike the bottom of conventional inverted-shape cloth foundations, the bottom plate protruding to the outside of the building can be omitted.
従って、型枠工事が容易になる。Therefore, formwork work becomes easier.
■ 建物の下部周囲の布基礎と、布基礎の内側の束基礎
とが連続しているから、横力が作用しても、布基礎のみ
に負担が係ることがなく、束下部の凸部へも横方が分散
して伝達される。■ Since the cloth foundation around the bottom of the building and the bundle foundation inside the cloth foundation are continuous, even if lateral force acts, the load does not apply only to the cloth foundation, and the load is applied to the convex part at the bottom of the bundle. It is also transmitted laterally in a dispersed manner.
○ さらに、基礎全体を布基礎というフレーム（ｆｒａ
ｍｅ ）の内側を平板状の基板で埋めた構造になってい
るから、横力による不拘な捩れや動きが少なくなり、上
部の軸組の構造体に及ぼす影響を低減させることができ
る。○ In addition, the entire foundation is constructed using a frame called a cloth foundation.
Since the inner side of the upper frame (me) is filled with a flat plate-like substrate, unrestrained twisting and movement due to lateral force is reduced, and the influence on the upper frame structure can be reduced.
■ また、布基礎の内側の地盤全面をコンクリート又は
鉄筋コンクリートで覆っているから、床下地面から上昇
する湿気を押えることができる。■ Also, since the entire ground inside the cloth foundation is covered with concrete or reinforced concrete, moisture rising from the ground beneath the floor can be suppressed.
また、床下を清潔に保ち、使い方によっては、床下の蓄
冷熱作用に利用することができる。It also keeps the area under the floor clean, and depending on how it is used, it can be used to store cold heat under the floor.
■ また、第３の発明の実施例に示すように、各束下部
の基板底面の凸部を布基礎の縦方向（または横、縦又は
斜め方向あるいはこれらの組み合わせ方向）に連続させ
、かつ布基礎下部と一体化させることにより、より強度
の大きい基礎構造にすることができる。■ In addition, as shown in the embodiment of the third invention, the convex portion on the bottom surface of the substrate at the bottom of each bundle is continuous in the vertical direction of the fabric foundation (or in the horizontal, vertical, or diagonal directions, or in a combination thereof), and By integrating it with the lower part of the foundation, it is possible to create a stronger foundation structure.
そして、布基礎が側梁、束が柱、基板底面の凸部が束間

えられるから、周辺に制弧をもつフラット・スラブ構造
と解することができ、連続した凸部にラーメンを構成す
る配筋を行うことにより、構造強度を極めて大にするこ
とができる。Since the cloth foundation is considered to be a side beam, the bundle is a column, and the convex part on the bottom of the board is a continuous column head (punch) that constitutes a rigid frame between the bundles, it can be interpreted as a flat slab structure with arc restraints around the periphery. The structural strength can be extremely increased by arranging reinforcement to form a rigid frame in continuous convex portions.
○ また、束間の間隔が大きく、束の受ける垂直荷重が
大きい場合は、ラーメンの効果により荷重を曲げモーメ
ントにより分散可能である。○ Also, if the distance between the bundles is large and the vertical load that the bundles receive is large, the load can be dispersed by bending moment due to the effect of the rigid frame.
■ 基板の板状部分の厚みを大にし配筋すると、剛性の
強いスラブ形式の建築とすることができ、建築全体の受
ける垂直荷重を分散させることができる。■ By increasing the thickness of the plate-shaped portion of the board and arranging reinforcement, it is possible to create a highly rigid slab-type building, and the vertical load that the entire building receives can be distributed.
■ 各東の受ける垂直荷重が小さい場合は、ラーメン効
果により単一に束が荷重を受ける場合よりも小さな断面
又は少ない鉄筋で対処できる。■ If the vertical load received by each east is small, it can be handled with a smaller cross section or fewer reinforcing bars than if a single bundle is loaded due to the rigid frame effect.
Ｏさらに、横力に対して束の下端部および布基礎下部の
曲げ剛性が大きくなる。Furthermore, the bending rigidity of the lower end of the bundle and the lower part of the fabric foundation increases with respect to lateral forces.
また、連続した基板底面の凸部と束基礎とが連続し、一
体止しているから、基板、布基礎全体のずれ移動に対す
る抵抗力が大であるなどの利点がある。Further, since the convex portion of the continuous substrate bottom surface and the bundle foundation are continuous and integrally fixed, there is an advantage that the resistance against displacement of the entire substrate and the cloth foundation is large.
