以下、図１乃至図３に沿って、本発明の実施の形態について説明する。     Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.

本発明に係るコンクリート構造物は、支柱状の構造体（以下、“支柱構造体”とする）を着脱可能に支持できるように構成されている。なお、本明細書におけるコンクリート構造物とは、コンクリート製の床版や壁や梁や柱等を含む概念であり、工場で製造する物（いわゆるプレキャスト製品）だけでなく、現場で製造する物（いわゆる現場打ち品）も含む概念である。また、本明細書における支柱構造体とは、
・ 建物を構築する際に床版に一時的に立設される仮設用手摺りや、
・ 建物を構築する際に床版や壁や柱に一時的に取り付けられる支柱
などを含む概念である。 The concrete structure according to the present invention is configured to be able to detachably support a columnar structure (hereinafter referred to as a “column structure”). In addition, the concrete structure in this specification is a concept including a concrete floor slab, a wall, a beam, a pillar, etc., and not only a thing manufactured at a factory (so-called precast product) but also a thing manufactured on the spot ( This is a concept including so-called on-site products. Moreover, with the support | pillar structure in this specification,
-Temporary handrails that are temporarily set up on the floor slab when building a building,
・ This concept includes floor slabs and columns that are temporarily attached to walls and pillars when building a building.

本発明に係るコンクリート構造物は、図１(a) (b) に符号１で例示するものであって、
・ 該コンクリート構造物１の略全体の外形を形成する構造物本体２（例えば、コンクリートや鉄筋で構成された複合体）と、
・ 支柱構造体３の基端部３ａを装入できるように構成された被装入手段４と、
を備えている。そして、この被装入手段４は、前記支柱構造体３の装脱方向Ａに沿って、
・ 前記支柱構造体３が挿入される挿入部４ａ１と、
・ 該支柱構造体３が螺入される螺入部４ａ２と、
を有している。図１(a) (b) に示す被装入手段４は、前記支柱構造体３を装入できる、鋼製の筒状部材であって、前記支柱構造体３を装入することのできる装入穴４ｂを形成した状態で前記構造物本体内に埋設されている。なお、コンクリート構造物がプレキャスト製品の場合には、該構造物をクレーンで吊り上げるための吊り上げ用部材（例えば、吊り上げ用のアイボルトを螺合するためのナット部材。図２(a)
の符号１１参照）が構造物本体中に埋設されているのが一般的であるが、その吊り上げ用部材１１（つまり、吊り上げ作業が終了してアイボルトが外された状態の吊り上げ用部材）に被装入手段１４（例えば、前記支柱構造体３を装入できる、鋼製の筒状部材）を取り付けるようにしても良い。この場合の被装入手段は、図２(b)
に詳示するように、
・ 吊り上げ用部材１１に螺合されるボルト部１４ａと、
・ 鋼製の筒状部材１４ｂと、
により構成すると良い。そして、該筒状部材１４ｂには、上述の挿入部や螺入部を設けておくと良い。 The concrete structure according to the present invention is exemplified by reference numeral 1 in FIGS. 1 (a) and 1 (b).
A structure main body 2 (for example, a composite composed of concrete or reinforcing bar) that forms the outer shape of substantially the entire concrete structure 1;
A loading means 4 configured to be able to load the base end portion 3a of the column structure 3;
It has. And this loading means 4 is along the loading / unloading direction A of the said column structure 3,
An insertion portion 4a 1 into which the support structure 3 is inserted;
A screw-in part 4a 2 into which the column structure 3 is screwed;
have. The loading means 4 shown in FIGS. 1 (a) and 1 (b) is a steel tubular member that can be loaded with the column structure 3, and can be loaded with the column structure 3. It is embedded in the structure body in a state where the entry hole 4b is formed. When the concrete structure is a precast product, a lifting member for lifting the structure with a crane (for example, a nut member for screwing a lifting eyebolt. FIG. 2 (a).
Is generally embedded in the main body of the structure, but the lifting member 11 (that is, the lifting member after the lifting operation is finished and the eyebolt is removed) is covered. You may make it attach the insertion means 14 (For example, the cylindrical member made from steel which can insert the said support | pillar structure 3). The loading means in this case is shown in FIG.
As detailed in
A bolt part 14a screwed to the lifting member 11,
A steel tubular member 14b;
It is good to comprise. And it is good to provide the above-mentioned insertion part and screwing part in this cylindrical member 14b.

ところで、上述の螺入部４ａ２は、支柱構造体３の基端部に形成されたネジ部３ａ２に螺合されるようなネジ部にしても良いが、図１(b) に符号４ｃで示すような突起部としても良い。そのような突起部４ｃはポンチ加工により簡単に形成できるので、被装入手段４の製造が簡単になるという効果を奏する。 Meanwhile, screw-join the club 4a 2 of the above may be the threaded portion, such as screwed into the screw portion 3a 2 formed at the base end portion of the bearing structure 3, but reference numeral 4c in FIG. 1 (b) It is good also as a projection part as shown. Since such a protrusion 4c can be easily formed by punching, there is an effect that the manufacture of the loading means 4 is simplified.

図１(a) (b) や図２(a) (b) に示すコンクリート構造物１，１０では、被装入手段４，１４の内部に支柱構造体３を装入するように構成されているが、その逆の構成（被装入手段の側にではなく支柱構造体の側に装入穴を形成しておいて、被装入手段を支柱構造体の装入穴に装入する構成）にしても良い。したがって、本明細書における“装入”とは、その両者、つまり、
・ 図１(a) (b) 及び図２(a) に示すように、被装入手段４，１４に支柱構造体３を入れることによって該支柱構造体３を装着する態様と、
・ その逆の態様（つまり、支柱構造体に被装入手段を入れることによって該支柱構造体を装着する態様）
の両方を含む概念である。また、本明細書における“挿入”とは、
・ 図１(a) (b) 及び図２(a) に示すように、被装入手段４，１４に支柱構造体３を挿し込むことによって入れる態様と、
・ その逆の態様（つまり、支柱構造体に被装入手段を挿し込むことによって入れる態様）
の両方を含む概念であって、挿入部にて被装入手段と支柱構造体とが接触しているか否かは問わない。さらに、本明細書における“螺入”とは、
・ 図１(a) (b) 及び図２(a) に示すように、支柱構造体３を被装入手段４，１４にねじ入れる態様と、
・ その逆の態様（つまり、被装入手段を支柱構造体にねじ入れる態様）
の両方を含む概念である。 The concrete structures 1 and 10 shown in FIGS. 1 (a) and 1 (b) and FIGS. 2 (a) and 2 (b) are configured to insert the column structure 3 into the loading means 4 and 14. However, the opposite configuration (a configuration in which a loading hole is formed not on the loading means side but on the column structure side, and the loading means is loaded into the loading hole of the column structure body. ). Therefore, “charging” in this specification means both of them, that is,
As shown in FIGS. 1 (a), 1 (b) and 2 (a), a mode in which the support structure 3 is mounted by inserting the support structure 3 into the loading means 4 and 14;
-The reverse mode (that is, the mode in which the column structure is mounted by inserting the loading means into the column structure)
It is a concept that includes both. In addition, “insertion” in this specification means
As shown in FIGS. 1 (a), (b) and 2 (a), a mode in which the support structure 3 is inserted into the loading means 4 and 14, and
・ The reverse mode (that is, the mode of inserting by inserting the loading means into the column structure)
It is a concept including both of the above, and it does not matter whether the loading means and the support structure are in contact with each other at the insertion portion. Furthermore, “screwing” in this specification means
As shown in FIGS. 1 (a), 1 (b) and 2 (a), the column structure 3 is screwed into the loading means 4 and 14, and
・ The reverse mode (that is, the mode in which the loading means is screwed into the column structure)
It is a concept that includes both.

なお、上述のような被装入手段４，１４に装入する支柱構造体３の基端部には、
・ 該被装入手段４，１４の挿入部（図１(b) の符号４ａ１参照）に挿入される被挿入部（同図の符号３ａ１参照）と、
・ 該被装入手段４，１４の螺入部（図１(b) の符号４ａ２参照）に螺合されるネジ部（同図の符号３ａ２参照）と、
を形成しておくと良い。この場合、被装入手段側の螺入部の長さ寸法（符号４ａ２で示す寸法）と、支柱構造体側のネジ部の長さ寸法（符号３ａ２で示す寸法）とを短くしておけば（つまり、ピッチ数を少なくしておけば）、支柱構造体３を装脱着する際に回す回数を少なくでき、その作業を容易にすることができる。この支柱構造体は、単一の部材（例えば、１本のパイプ部材）で構成しても良いが、複数の部材（例えば、複数のパイプ部材）を連結して構成しても良い。図１(a) に示す支柱構造体は複数の部材で構成されており、符号３０は、両端にネジが切られた連結パイプを示し、符号３１は、いわゆる単管パイプを示す。このような連結パイプ３０を使用すれば、色々な長さの単管パイプを接続し、支柱構造体の長さを自由に変更できる。 In addition, in the base end part of the column structure 3 to be loaded into the loading means 4 and 14 as described above,
An inserted portion (see reference numeral 3a 1 in the figure) to be inserted into the insertion part of the loading means 4 and 14 (see reference numeral 4a 1 in FIG. 1B);
· Threaded join the club of該被charging means 4, 14 (see reference numeral 3a 2 of the drawing) screw portion to be screwed in (numeral 4a see 2 in FIG. 1 (b)),
It is good to form. In this case, the length of the threaded join the club of HiSoIri means side (dimension indicated by reference numeral 4a 2), if a shorter and length of the threaded portion of the pillar structure side (dimension indicated by reference numeral 3a 2) (That is, if the number of pitches is reduced), the number of rotations when attaching and detaching the support structure 3 can be reduced, and the work can be facilitated. Although this support | pillar structure may be comprised with a single member (for example, one pipe member), you may comprise it by connecting a some member (for example, several pipe member). The strut structure shown in FIG. 1 (a) is composed of a plurality of members. Reference numeral 30 indicates a connecting pipe with screws at both ends, and reference numeral 31 indicates a so-called single pipe. If such a connection pipe 30 is used, single pipe pipes of various lengths can be connected, and the length of the column structure can be freely changed.

ところで、支柱構造体側のネジ部３ａ２は、当然ながら、被装入手段４に装入する際に螺入部４ａ２に螺合される位置に形成されている必要がある。例えば、ネジ部３ａ２が、図３(a) に示すように支柱構造体３の先端（図では下端）に形成されている場合には、螺入部４ａ２は被装入手段４の奥側（図では下側）に形成しておく必要があり、ネジ部３ａ２が図３(b)
に示す位置（つまり、先端よりも少し離れた位置）に形成されている場合には、螺入部４ａ２は、それに対応した位置に形成しておく必要がある。さらには、図３(c)
に示すように、前記支柱構造体３が前記被装入手段４に装入された状態で、該支柱構造体側のネジ部３ａ２が前記被装入手段側の螺入部４ａ２よりも、該被装入手段４の奥側に配置されるように構成しても良い。以下、このような構成の効果について説明する。 Incidentally, the screw portion 3a 2 on the column structure side needs to be formed at a position where the screw portion 3a 2 is screwed to the screw portion 4a 2 when the screw portion 3a 2 is inserted into the loading means 4. For example, the screw portion 3a 2 is, if (in the figure the lower end) distal end of the bearing structure 3, as shown in FIG. 3 (a) is formed on the inner side of the threaded join the club 4a 2 is HiSoIri means 4 (The lower side in the figure) needs to be formed, and the screw portion 3a 2 is formed in FIG.
Position shown in (i.e., a position slightly away from the tip) when it is formed, the threaded join the club 4a 2, it is necessary to form at positions corresponding thereto. Furthermore, FIG. 3 (c)
As shown in FIG. 4, in the state in which the column structure 3 is inserted into the loading means 4, the screw portion 3a 2 on the column structure side is more than the screw portion 4a 2 on the loading means side. You may comprise so that it may arrange | position to the back side of the to-be-inserted means 4. FIG. Hereinafter, the effect of such a configuration will be described.

いま、図３(a) や(b) に示す構造のものでは、支柱構造体３がコンクリート構造物１に装着されている時は支柱構造体３のネジ部３ａ２は被装入手段４の螺入部４ａ２に螺合されることとなる。この場合、ネジ部３ａ２が螺入部４ａ２に ほんの少しだけ係止されてさえいれば、支柱構造体３は被装入手段４から抜けることは無いが、該支柱構造体３が僅かに回転されただけでネジ部３ａ２と螺入部４ａ２との係合が外れてしまうおそれもある。そして、ネジ部３ａ２と螺入部４ａ２とが確実に係合状態にあるかどうかを確かめるには、支柱構造体３を掴んで“閉じ方向”に強く回転させる必要があり、その作業が煩雑であるという問題がある。これに対し、図３(c)
に示すような構成にすれば、支柱構造体３がコンクリート構造物１に装着されている時は支柱構造体３のネジ部３ａ２は被装入手段４の螺入部４ａ２に螺合されてはおらず、該支柱構造体３は 矢印Ａに示す方向に 上下に僅かながらも“遊び”がある状態となる（当然ながら、支柱構造体３における、ネジ部３ａ２以外の部分と螺入部４ａ２との間に隙間が形成されている必要がある）。つまり、矢印Ａで示す方向に支柱構造体３を上下動させれば 該支柱構造体３は動くものの、被装入手段４から抜け出ることは無いという状態になる。したがって、支柱構造体３を抜こうとして抜けなければ、該支柱構造体３は被装入手段４に確実に支持されていることとなり、その確認作業を容易に行えるという効果がある。なお、その場合、支柱構造体３は、被装入手段４に支持されている状態でも軸方向Ａには多少移動することとなるが、そのような遊びが問題にならない場合も多い。例えば、図１(a)
に示すように、コンクリート構造物としてのコンクリート床版１の端縁部に被装入手段４を設け、該被装入手段４に支柱構造体３を立設させて仮設の手摺りと利用するような場合は、該支柱構造体３には、水平方向の力や下方向の力は作用するものの、上方向の力は作用しないのが普通である。したがって、このような使用態様の場合には、図３(c)
に示すような構造は適している。 Now, in the structure shown in FIGS. 3 (a) and 3 (b), when the support structure 3 is attached to the concrete structure 1, the threaded portion 3 a 2 of the support structure 3 is attached to the loading means 4. so that the screwed into threaded join the club 4a 2. In this case, as long as the screw part 3a 2 is only slightly locked to the screw part 4a 2 , the support structure 3 will not come out of the loading means 4, but the support structure 3 will rotate slightly. There is a possibility that the engagement between the screw portion 3a 2 and the screw-in portion 4a 2 is disengaged only by being done. Then, check if the screw portion 3a 2 and the threaded join the club 4a 2 is securely in the engaged state, it is necessary to rotate strongly to "closing direction" grabbed bearing structure 3, complicated the work There is a problem that. In contrast, Fig. 3 (c)
If the configuration as shown in, when the bearing structure 3 is attached to the concrete structure 1 is screw part 3a 2 of the bearing structure 3 is screwed into threaded join the club 4a 2 of HiSoIri means 4 The support structure 3 is in a state where there is a slight “play” in the direction shown by the arrow A (naturally, the support structure 3 is not provided with the screw portion 3a 2 and the screw-in portion 4a 2. Need to have a gap between them). That is, if the column structure 3 is moved up and down in the direction indicated by the arrow A, the column structure 3 moves, but does not come out of the loading means 4. Therefore, if the column structure 3 is not pulled out without being pulled out, the column structure 3 is surely supported by the loading means 4, and the confirmation work can be easily performed. In this case, the column structure 3 moves somewhat in the axial direction A even when it is supported by the loading means 4, but such play often does not become a problem. For example, Fig. 1 (a)
As shown in FIG. 4, the loading means 4 is provided at the edge of the concrete floor slab 1 as a concrete structure, and the column structure 3 is erected on the loading means 4 to be used as a temporary handrail. In such a case, although a horizontal force and a downward force are applied to the support structure 3, an upward force is generally not applied. Therefore, in the case of such a usage mode, FIG.
A structure as shown in FIG.
