A container is originally a structure for freight transportation, but since it has a robust structure and a large space can be secured inside, it may be used as a building for warehouses, stores, residences, and the like.
When constructing a new container as a building, it is necessary to apply for building confirmation before the start of construction, receive the building confirmation, and obtain a confirmation certificate. In order to receive building confirmation, in addition to the structural strength of the container itself, a secure connection between the container and the foundation is required, and when the containers are stacked one above the other, the upper and lower containers must be securely connected.

従来技術には以下のような問題点がある。
<1>特許文献1、2のコンテナは、支柱が断面L字形状を呈するため、曲げや座屈に対する断面性能が低く、支柱として十分な剛性を確保できない。またベースプレート(平板)が支柱に対し片持ちの構造となるため、地震や風による水平力を受けて変形しやすい。更に、ボルトとナットが外部に露出するため、隙間に雨水が溜まって腐食しやすく、外観上も美観を欠く。
<2>特許文献3のコンテナのように、支柱に角形鋼管を採用すれば、支柱自体の剛性は確保できる。しかし、このコンテナは支柱とコーナーキャスティングが別部材であり、この接合部が弱部となるため、コンテナ構造全体としての剛性を確保することができない。
<3>特許文献4のコンテナは、支柱が角形鋼管の一本物からなるが、支柱の直下ではなく、支柱の外側に延出したベースプレートの耳部を介して基礎と連結するため、連結強度が低く、結局のところ支柱の性能がコンテナ構造全体の剛性に貢献していない。
<4>特許文献2〜4のコンテナは、円形のボルト孔にボルトを挿通して連結する。しかし実際には、コンテナの製造誤差や施工誤差によって、ボルトとボルト孔との位置にずれが生じるのが通常であり、この位置ずれを現場で調整できないため、著しく施工性に劣る。
<5>特許文献1のコンテナは、ボルト孔を長孔にすることによって、ボルト位置のずれを吸収することができるが、ボルト孔の内壁とボルトの外周との間に空間が生じるため、地震や台風などによってコンテナが水平に移動したり、ボルトの周囲に応力が集中してベースプレートが変形し、連結が損なわれるおそれがある。
The prior art has the following problems.
<1> In the containers of Patent Documents 1 and 2, since the columns have an L-shaped cross section, the cross-sectional performance against bending and buckling is low, and sufficient rigidity cannot be secured as the columns. In addition, since the base plate (flat plate) has a cantilevered structure with respect to the columns, it is easily deformed by the horizontal force caused by an earthquake or wind. Furthermore, since the bolts and nuts are exposed to the outside, rainwater collects in the gaps and is easily corroded, which makes the appearance unattractive.
<2> If a square steel pipe is used for the support column as in the container of Patent Document 3, the rigidity of the support column itself can be ensured. However, in this container, the column and the corner casting are separate members, and this joint is a weak part, so that the rigidity of the container structure as a whole cannot be ensured.
<3> In the container of Patent Document 4, the strut is made of a single square steel pipe, but the strut is connected to the foundation not directly under the strut but through the ear portion of the base plate extending to the outside of the strut, so that the connection strength is high. It is low, and after all, the performance of the columns does not contribute to the rigidity of the entire container structure.
<4> The containers of Patent Documents 2 to 4 are connected by inserting bolts into circular bolt holes. However, in reality, the position of the bolt and the bolt hole usually shifts due to a manufacturing error or a construction error of the container, and since this position shift cannot be adjusted on site, the workability is significantly inferior.
<5> The container of Patent Document 1 can absorb the deviation of the bolt position by making the bolt hole elongated, but since a space is created between the inner wall of the bolt hole and the outer circumference of the bolt, an earthquake occurs. There is a risk that the container will move horizontally due to a typhoon or the like, or that stress will be concentrated around the bolts and the base plate will be deformed, resulting in impaired connection.

The partition plate 14 is an inner diaphragm that reinforces the support column A1.
The partition plate 14 is provided in the connecting space 15 at a position facing the connecting plate 13, and partitions the upper portion of the connecting space 15.
In this example, as the partition plate 14, a steel plate made of rolled steel for general structure, which is welded to the inside of the joint portion between the support column A1 and the beam member A2, is adopted.
The partition plate 14 prevents the side surface of the support column A1 from being deformed by the horizontal force acting on the beam member A2. The partition plate 14 is not an essential component.

<4.4>連結空間。
連結空間15は、支圧板20や嵌合スペーサ30等の連結部材を収容する空間である。
連結空間15は、支柱A1の内壁によって周囲四面を区画され、仕切板14と連結板13によって上下を区画される。
連結空間15は、少なくとも第一開口11aと連結開口13aによって外部と連通する。なお、本例ではさらに第二開口12aを有する。
本発明の連結構造1は、支圧板20等を外部に露出させず、連結空間15内に収容することによって、アンカーボルト41や支圧板20等の隙間に雨水が浸入して腐食することを防ぐことができる。
<4.4> Connected space.
The connecting space 15 is a space for accommodating connecting members such as the bearing plate 20 and the fitting spacer 30.
The connecting space 15 is divided into four peripheral surfaces by the inner wall of the support column A1, and is partitioned above and below by the partition plate 14 and the connecting plate 13.
The connected space 15 communicates with the outside by at least the first opening 11a and the connecting opening 13a. In this example, the second opening 12a is further provided.
The connecting structure 1 of the present invention prevents rainwater from entering the gaps between the anchor bolts 41 and the bearing plate 20 and corroding by accommodating the bearing plate 20 and the like in the connecting space 15 without exposing them to the outside. be able to.

<5>支圧板。
支圧板20は、連結板13を支圧する板材である。
本例では支圧板20として、一般構造用圧延鋼材(SS400)からなる円形プレートを採用する。
支圧板20は、両面を連通する2つのボルト孔20aを有する。ただしボルト孔20aの数はこれに限らず、1つ又は3つ以上としてもよい。
支圧板20は、連結空間15において、ボルト孔20a内にアンカーボルト41が連通し、底面が連結板13に接面し、上面がボルト孔20a付近でワッシャ60と接面する。
支圧板20の直径は、支柱A1の連結空間15における対向する内壁間の距離より小さく、かつ連結開口13aの長径より大きく構成する。
これによって、連結開口13aの上部を完全に覆い、連結板13を確実に支圧することが可能となる。
<5> Support plate.
The bearing plate 20 is a plate material that supports the connecting plate 13.
In this example, as the bearing plate 20, a circular plate made of rolled steel for general structure (SS400) is adopted.
The bearing plate 20 has two bolt holes 20a that communicate with each other on both sides. However, the number of bolt holes 20a is not limited to this, and may be one or three or more.
In the connecting space 15, the anchor bolt 41 communicates with the bolt hole 20a, the bottom surface of the bearing plate 20 contacts the connecting plate 13, and the upper surface of the bearing plate 20 contacts the washer 60 in the vicinity of the bolt hole 20a.
The diameter of the bearing plate 20 is smaller than the distance between the opposing inner walls in the connecting space 15 of the support column A1 and larger than the major axis of the connecting opening 13a.
As a result, the upper part of the connecting opening 13a can be completely covered, and the connecting plate 13 can be reliably supported.

<6>嵌合スペーサ。
嵌合スペーサ30は、連結開口13aの隙間を塞ぐスペーサである。
本例では嵌合スペーサ30として、一般構造用圧延鋼材の鋼板を採用する。
嵌合スペーサ30は、両面を連通する2つのボルト孔30aを有する。ただしボルト孔30aの数はこれに限らず、1つ又は3つ以上としてもよい。
嵌合スペーサ30は、ボルト孔30a内にアンカーボルト41が連通し、連結開口13a内に嵌め込まれる。嵌合スペーサ30の底面は基礎Bの上面に接面し、嵌合スペーサ30の上面は支圧板20の底面と接面する。
嵌合スペーサ30の外形は、連結開口13aの形状と相似する。ここで「連結開口の形状と相似する」とは、連結板13の平面視において嵌合スペーサ30の外周の形状が連結開口13aの内周の形状と略一致し、嵌合スペーサ30を連結開口13a内にほぼ隙間なく嵌め込めることを意味する。
嵌合スペーサ30の厚みは、連結開口13aの深さとほぼ同一とする。
本発明の連結構造1は、連結開口13aの周壁とアンカーボルト41の間に嵌合スペーサ30を嵌め込んで固定することで、地震や台風などの外部応力による、コンテナAの水平移動を規制するとともに、アンカーボルト41の引張応力による、支圧板20の撓み変形を防ぐことができる。
<6> Fitting spacer.
The fitting spacer 30 is a spacer that closes the gap of the connecting opening 13a.
In this example, a steel plate made of rolled steel for general structure is used as the fitting spacer 30.
The fitting spacer 30 has two bolt holes 30a that communicate with each other on both sides. However, the number of bolt holes 30a is not limited to this, and may be one or three or more.
In the fitting spacer 30, the anchor bolt 41 communicates with the bolt hole 30a and is fitted into the connecting opening 13a. The bottom surface of the fitting spacer 30 is in contact with the upper surface of the foundation B, and the upper surface of the fitting spacer 30 is in contact with the bottom surface of the bearing plate 20.
The outer shape of the fitting spacer 30 is similar to the shape of the connecting opening 13a. Here, "similar to the shape of the connecting opening" means that the shape of the outer circumference of the fitting spacer 30 substantially matches the shape of the inner circumference of the connecting opening 13a in the plan view of the connecting plate 13, and the fitting spacer 30 is connected to the connecting opening. It means that it can be fitted in 13a with almost no gap.
The thickness of the fitting spacer 30 is substantially the same as the depth of the connecting opening 13a.
The connecting structure 1 of the present invention regulates the horizontal movement of the container A due to external stress such as an earthquake or a typhoon by fitting and fixing the fitting spacer 30 between the peripheral wall of the connecting opening 13a and the anchor bolt 41. At the same time, it is possible to prevent the bearing plate 20 from bending and deforming due to the tensile stress of the anchor bolt 41.

<7>支圧板と嵌合スペーサの寸法。
支圧板20及び嵌合スペーサ30の直径と厚みは、第一開口11a又は第二開口12aを通過可能な寸法の組み合わせとする。
例えば、支圧板20の直径を第一開口11aの長径より小さくし、支圧板20や嵌合スペーサの厚みを第一開口11aの短径より小さくする。
これによって、コンテナAを設置面上に吊り下ろした後に、隅角部10の外側から連結空間15内に支圧板20及び嵌合スペーサ30を差し入れて施工することが可能となる。
<7> Dimensions of bearing plate and fitting spacer.
The diameter and thickness of the bearing plate 20 and the fitting spacer 30 are a combination of dimensions that allow the first opening 11a or the second opening 12a to pass through.
For example, the diameter of the bearing plate 20 is made smaller than the major diameter of the first opening 11a, and the thickness of the bearing plate 20 and the fitting spacer is made smaller than the minor diameter of the first opening 11a.
As a result, after the container A is hung on the installation surface, the bearing plate 20 and the fitting spacer 30 can be inserted into the connecting space 15 from the outside of the corner portion 10 for construction.

<8>アンカーボルト、ナット、ワッシャ。
アンカーボルト41、ナット50、及びワッシャ60は、支圧板20を連結板13に支圧する締結部材である。
本例ではアンカーボルト41として、基端が基礎B内で水平方向に曲折し、先端が基礎Bの上面から上方に突出する、L字形状のアンカーボルトを採用する。
本例では、基礎B内に2本のアンカーボルト41を配置し、各アンカーボルト41の先端は、それぞれ、嵌合スペーサ30のボルト孔30aと支圧板20のボルト孔20aを連通し、支圧板20上に突出したネジ部に1枚のワッシャ60を環設して2つのナット50を螺着している。
なお、ナット50の数やワッシャ60の配置はこれに限られない。
<8> Anchor bolts, nuts, washers.
The anchor bolt 41, the nut 50, and the washer 60 are fastening members that support the bearing plate 20 to the connecting plate 13.
In this example, as the anchor bolt 41, an L-shaped anchor bolt whose base end is bent horizontally in the foundation B and whose tip protrudes upward from the upper surface of the foundation B is adopted.
In this example, two anchor bolts 41 are arranged in the foundation B, and the tip of each anchor bolt 41 communicates with the bolt hole 30a of the fitting spacer 30 and the bolt hole 20a of the support plate 20, respectively, and supports the support plate. One washer 60 is ringed on the screw portion protruding above 20 and two nuts 50 are screwed together.
The number of nuts 50 and the arrangement of washers 60 are not limited to this.

<9>連結方法(図3)。
本発明のコンテナの連結構造1は、例えば以下の手順で施工する。なお図3では、説明の便宜のため、第一側板11の一部と第二側板12の一部を透過して表示し、支柱A1のうち仕切板14より上部を省略している。
<9> Connection method (Fig. 3).
The container connection structure 1 of the present invention is constructed by, for example, the following procedure. In FIG. 3, for convenience of explanation, a part of the first side plate 11 and a part of the second side plate 12 are transparently displayed, and the upper part of the support column A1 above the partition plate 14 is omitted.

<9.1>基礎の設置。
コンテナ設置面における、支柱A1の設置位置を所定の深さ掘削する。
掘削面に砕石を敷設して敷き均し、砕石上に所定厚さの捨てコンクリートを打設する。
捨てコンクリートの硬化後、捨てコンクリートの上部に型枠を組んで、型枠内に鉄筋を組み立てる。型枠内に2本のアンカーボルト41を据え付けた後、地盤の高さまでコンクリートを打設する。
コンクリートの硬化後に型枠を脱型することによって、設置面内に、上部からアンカーボルト41が突出した基礎Bが構築される。基礎Bの周囲は必要に応じて埋め戻す。
なお、基礎Bの設置方法は上記に限らず、例えば基礎Bは無筋コンクリートであってもよい。また、現場打設によらず、二次製品の基礎ブロックを設置面内に埋設する方法であってもよい。
<9.1> Installation of foundation.
The installation position of the support column A1 on the container installation surface is excavated to a predetermined depth.
Crushed stone is laid on the excavated surface and leveled, and a predetermined thickness of discarded concrete is placed on the crushed stone.
After the waste concrete is hardened, the formwork is assembled on the top of the waste concrete, and the reinforcing bars are assembled in the formwork. After installing the two anchor bolts 41 in the formwork, concrete is poured to the height of the ground.
By removing the formwork after the concrete has hardened, a foundation B in which the anchor bolts 41 protrude from the upper part is constructed in the installation surface. The area around the foundation B is backfilled as needed.
The method of installing the foundation B is not limited to the above, and for example, the foundation B may be unreinforced concrete. Further, a method of burying the foundation block of the secondary product in the installation surface may be used regardless of the method of placing in the field.

<9.2>コンテナの配置。
コンテナAを設置面上に吊り下ろす(図3(a))。この際、コンテナA四隅の隅角部10を基礎Bの直上に位置合わせし、連結開口13aを通して、アンカーボルト41の先端を連結空間15内に挿入する(図3(b))。
ここで、隅角部10底部の連結開口13aは長孔であるため、仮にコンテナAの製造誤差と基礎Bの施工誤差等によって、隅角部10とアンカーボルト41の相対位置にずれが生じた場合であっても、誤差を連結開口13a内に吸収することができる。
なお、コンテナAの吊り下ろし前に、基礎Bの上に無収縮モルタルを盛って、基礎Bと連結板13の隙間を埋めてもよい。
<9.2> Placement of containers.
Container A is hung on the installation surface (Fig. 3 (a)). At this time, the corner portions 10 at the four corners of the container A are aligned directly above the foundation B, and the tip of the anchor bolt 41 is inserted into the connected space 15 through the connecting opening 13a (FIG. 3B).
Here, since the connecting opening 13a at the bottom of the corner portion 10 is a long hole, the relative positions of the corner portion 10 and the anchor bolt 41 are displaced due to a manufacturing error of the container A and a construction error of the foundation B. Even in this case, the error can be absorbed in the connecting opening 13a.
Before hanging the container A, a non-shrink mortar may be placed on the foundation B to fill the gap between the foundation B and the connecting plate 13.

<9.3>嵌合スペーサの配置。
第一開口11a又は第二開口12aを通して、嵌合スペーサ30を連結空間15内に差し入れる。
連結空間15内で、アンカーボルト41の先端に嵌合スペーサ30のボルト孔30aを通して(図3(c))、嵌合スペーサ30を連結開口13a内に嵌め込む。
仮に隅角部10とアンカーボルト41の位置にずれがあり、嵌合スペーサ30を連結開口13a内に嵌め込めない場合には、嵌合スペーサ30にボルト孔30aを開け直すことで、現場で微調整することができる。
このように、アンカーボルト41の位置の誤差調整をコンテナAの吊り下ろし作業に影響させず、吊り下ろし後に調整できることで、コンテナAの設置を容易にすることができる。
<9.3> Arrangement of fitting spacers.
The fitting spacer 30 is inserted into the connected space 15 through the first opening 11a or the second opening 12a.
In the connecting space 15, the bolt hole 30a of the fitting spacer 30 is passed through the tip of the anchor bolt 41 (FIG. 3C), and the fitting spacer 30 is fitted into the connecting opening 13a.
If the corners 10 and the anchor bolts 41 are misaligned and the fitting spacer 30 cannot be fitted into the connecting opening 13a, the bolt holes 30a can be re-drilled in the fitting spacer 30 to make fine on-site. Can be adjusted.
As described above, the error adjustment of the position of the anchor bolt 41 does not affect the hanging work of the container A and can be adjusted after the hanging, so that the installation of the container A can be facilitated.

<9.4>支圧板の配置。
第一開口11a又は第二開口12aを通して、支圧板20を連結空間15内に差し入れる。
連結空間15内で、アンカーボルト41の先端に支圧板20のボルト孔20aを通して嵌合スペーサ30の上に下ろし(図3(d))、支圧板20の下面を連結板13の上面に接面させる。
隅角部10とアンカーボルト41の位置にずれがある場合には、嵌合スペーサ30と同様に、支圧板20にボルト孔を開け直して微調整する。
<9.4> Arrangement of bearing plates.
The bearing plate 20 is inserted into the connected space 15 through the first opening 11a or the second opening 12a.
In the connecting space 15, the bolt hole 20a of the bearing plate 20 is passed through the tip of the anchor bolt 41 and lowered onto the fitting spacer 30 (FIG. 3D), and the lower surface of the bearing plate 20 is in contact with the upper surface of the connecting plate 13. Let me.
If the positions of the corner portion 10 and the anchor bolt 41 are misaligned, the bolt holes are re-drilled in the bearing plate 20 and fine adjustment is made in the same manner as in the fitting spacer 30.

<9.5>ナットの螺着。
アンカーボルト41の先端にワッシャ60を通し、ナット50を螺着する(図3(e))。
ナット50は、例えば、第一開口11aから連結空間15内に指を入れてアンカーボルト41の先端に仮留めし、電動締結具Cで螺着して締結する。
本例では、電動締結具Cとして、回転部C1に角度調整アタッチメントを付設したインパクトレンチを採用する。角度調整アタッチメントによって、回転部C1先端の回転軸を、回転部C1基端の回転軸から屈折させ、回転部C1を隅角部10の外側から第一開口11a内に差し込んで、ナット50をアンカーボルト41に螺着することができる(図4)。
なお、ナット50の螺着は電動工具Cによるものに限らず、第一開口11aから連結空間15内にラチェットレンチ等の手動工具を差し入れて、手動で螺着することも可能である。
<9.5> Screwing of nuts.
A washer 60 is passed through the tip of the anchor bolt 41, and a nut 50 is screwed (FIG. 3 (e)).
For example, the nut 50 is fastened by inserting a finger into the connecting space 15 from the first opening 11a, temporarily fixing the nut 50 to the tip of the anchor bolt 41, and screwing it with the electric fastener C.
In this example, an impact wrench with an angle adjusting attachment attached to the rotating portion C1 is used as the electric fastener C. By the angle adjustment attachment, the rotating shaft at the tip of the rotating portion C1 is bent from the rotating shaft at the base end of the rotating portion C1, the rotating portion C1 is inserted into the first opening 11a from the outside of the corner portion 10, and the nut 50 is anchored. It can be screwed onto the bolt 41 (FIG. 4).
The nut 50 is not only screwed by the electric tool C, but it is also possible to insert a manual tool such as a ratchet wrench into the connecting space 15 from the first opening 11a and manually screw the nut 50.

<9.6>連結方法の特徴。
本発明のコンテナ連結方法は、支圧板20と嵌合スペーサ30が薄板状の別部材からなるため、第一開口11aが比較的小さくても、隙間から差し入れて連結空間15内に配置することができる。
また、回転部C1を屈折させた電動締結具Cを用いることで、回転部C1の先端を第一開口11aに差し入れて、ナット50を螺着することができる。
以上より、第一開口11aを小さく構成し、支柱A1の断面欠損量を低減して十分な有効断面積を確保することで、支柱A1の剛性を高め、コンテナAに建築物としての十分な構造強度を発揮させることが可能となる。
<9.6> Features of the connection method.
In the container connecting method of the present invention, since the bearing plate 20 and the fitting spacer 30 are made of separate thin plate-shaped members, even if the first opening 11a is relatively small, it can be inserted through a gap and arranged in the connecting space 15. can.
Further, by using the electric fastener C in which the rotating portion C1 is refracted, the tip of the rotating portion C1 can be inserted into the first opening 11a and the nut 50 can be screwed.
Based on the above, the rigidity of the support column A1 is increased by making the first opening 11a small, reducing the amount of cross-sectional loss of the support column A1 and ensuring a sufficient effective cross-sectional area, and the container A has a sufficient structure as a building. It is possible to exert strength.
