Description
【考案の詳細な説明】 本考案は基礎構造に関する。[Detailed explanation of the idea] The present invention relates to basic structures.
従来、構造物の基礎として採用されているべた
基礎ａやフーチングｂ（第１図参照）の施工にお
いては、型枠を用いコンクリートを流し込むだけ
で、特に表面処理を行なうことはしない。これら
の基礎の地耐力は主に基礎底面から上部構造物ｃ
の荷重を地盤ｄに伝達することにより得られてい
る。基礎側面は比較的滑らかであり、そのため荷
重が基礎側面から地盤に伝達されることはほとん
ど無いといつて良い。従つて基礎の地耐力を増す
ためには基礎の底面積を増す必要があり、コスト
がかかる欠点がある。 Conventionally, in the construction of flat foundations a and footings b (see Figure 1), which have been adopted as the foundations of structures, concrete is simply poured using formwork, without any particular surface treatment. The soil bearing capacity of these foundations is mainly determined from the bottom of the foundation to the upper structure c.
It is obtained by transmitting the load of 1 to the ground d. The sides of the foundation are relatively smooth, so it can be said that almost no load is transferred from the sides of the foundation to the ground. Therefore, in order to increase the bearing capacity of the foundation, it is necessary to increase the bottom area of the foundation, which has the disadvantage of being costly.
そこで本考案は、前記欠点を除去し、基礎のコ
ンクリート容積を大幅に増やすことなく、簡便か
つ低コストの施工で地耐力を大巾に増加すること
ができる基礎構造を提供することを目的としたも
のである。 Therefore, the present invention aims to eliminate the above-mentioned drawbacks and provide a foundation structure that can greatly increase the bearing capacity of the soil through simple and low-cost construction without significantly increasing the concrete volume of the foundation. It is something.
本考案の実施例を以下第２図に従つて詳細に説
明する。 An embodiment of the present invention will be described in detail below with reference to FIG.
本考案による基礎は次の要領で施工される。 The foundation according to this invention will be constructed in the following manner.
(1) 地中に埋まる基礎の周囲を第２図ａのように
Ｖ字型に掘削し、砕石１をつめておく。（２は
鉄筋である）
(2) 地表面上の基礎に対しては周囲に型枠３を設
置し、コンクリート４を打設する。基礎本体Ａ
が形成される。（第２図ｂ参照）
(3) 基礎本体Ａの周囲に対してもコンクリートを
打設する。基礎底面より上方に向けて拡がつた
傾斜面B′を有する、砕石１混りの張出し部基礎
Ｂを形成される。（第２図ｃ参照）
(4) 養生後、型枠をとり外し、基礎は完成する。
（第２図ｄ参照）
本実施例の基礎は従来の基礎Ａの側方に非常に
粗い仕上り面をもつ砕石１混りのコンクリート４
を結合させた、張出部Ｂ構造となつており、次の
効果を有する。(1) Excavate the area around the foundation to be buried in the ground in a V-shape as shown in Figure 2 a, and fill it with crushed stone 1. (2 is reinforcing steel) (2) For the foundation on the ground surface, formwork 3 is installed around it, and concrete 4 is poured. Basic body A
is formed. (See Figure 2b) (3) Concrete is also poured around the foundation body A. An overhanging foundation B made of crushed stone is formed, having a slope B' extending upward from the bottom of the foundation. (See Figure 2c) (4) After curing, remove the formwork and complete the foundation.
(See Figure 2 d) The foundation of this example is concrete 4 mixed with 1 crushed stone, which has a very rough finished surface on the side of the conventional foundation A.
The projecting part B structure has the following effects.
基礎Ａの側面と地盤とが緊密に接触することに
なるので、上部構造物による荷重が基礎底面のみ
ならず、側面B′からも地盤に伝達されることにな
る。従つて支持力を増加させ、かつ基礎の沈下も
押さえることができることになるので、地耐力が
増すことになる。 Since the side surface of the foundation A is in close contact with the ground, the load from the upper structure is transmitted to the ground not only from the bottom surface of the foundation but also from the side surface B'. Therefore, it is possible to increase the bearing capacity and prevent the foundation from sinking, resulting in an increase in the bearing capacity of the ground.
要するに本考案によれば、鉄筋入り基礎の外周
と周囲の地盤との間に前記基礎の外周と一体に構
成すべく、砕石を主とし、その上端を地面と同一
レベルとする張出し部を設けて成ることを特徴と
することにより、基礎の側面を粗く仕上げて荷重
を基礎の側面からも地盤に伝達することになり、
支持力を増し、沈下を押えて地耐力を増す。 In short, according to the present invention, an overhang is provided between the outer periphery of the reinforced foundation and the surrounding ground, which is mainly made of crushed stone and whose upper end is at the same level as the ground, in order to be integrated with the outer periphery of the foundation. This feature allows the sides of the foundation to be roughened and the load to be transmitted from the sides of the foundation to the ground.
It increases the bearing capacity, suppresses subsidence, and increases the bearing capacity of the ground.
