Description

本発明は、建築現場に設置されたコンクリート部材の上に安全柵を固定するために使用される土台に関する。 The present invention relates to a base used for fixing a safety fence on a concrete member installed at a construction site.

プレキャストのコンクリート部材を用いて建築物を造るときに、建築現場に設置されたコンクリート部材の上で作業を行う際に作業者が転落して怪我等を負わないために、コンクリート上に安全柵が仮設される。この場合、コンクリート部材の上に所定の間隔を開けて複数の支柱をコンクリート部材に立設して、それらの隣接する支柱を渡すように手摺等が横架される。 When building a building using precast concrete members, there is a safety fence on the concrete so that workers do not fall and injure when working on the concrete members installed at the construction site. Temporary. In this case, a plurality of columns are erected on the concrete member with a predetermined interval on the concrete member, and a handrail or the like is horizontally placed so as to pass the adjacent columns.

そして、プレキャストのコンクリート部材は、予めコンクリート工場などで製造されてから建築現場に輸送されて、設置される。一般に建築現場で使用されるコンクリート部材の重量が大きいために、クレーンなどの機械により移動させられるところ、クレーンなどにより移動させやすいように、コンクリート部材には表面から連結部の一種であるアンカーが突出して設けられている。 Then, the precast concrete member is manufactured in advance in a concrete factory or the like and then transported to the construction site and installed. In general, the weight of a concrete member used at a construction site is large, and when it is moved by a crane or other machine, an anchor, which is a kind of connecting portion, protrudes from the surface so that the concrete member can be easily moved by a crane or the like. Is provided.

このコンクリート部材の表面から突出したアンカーを利用して、上述した仮設の安全柵を設ける試みが種々行われている。 Various attempts have been made to provide the above-described temporary safety fence using an anchor protruding from the surface of the concrete member.

例えば、特許文献１には、デーハーアンカー２の頭部２ａにその横方向から固定ボルト３底部のＣ型金具３ａを嵌合させる第一工程、取付台４を凹部１を囲んで取り付け、その際固定ボルト３を取付台４より突出させる第二工程、固定ボルト３を安全柵７の柱５をねじ込むとともに締め付ける第三工程、コンクリート製品６上に安全柵７を構築する第四工程からなる安全柵の柱の固定工法が開示されている。なお、当該符号は、特許文献１に記載されている符号である。 For example, in Patent Document 1, the first step of fitting the C-shaped metal fitting 3a at the bottom of the fixing bolt 3 from the lateral direction to the head 2a of the dayher anchor 2, the mounting base 4 is attached surrounding the recess 1, Safety fence consisting of the second step of projecting the fixing bolt 3 from the mounting base 4, the third step of screwing and fastening the fixing bolt 3 to the pillar 5 of the safety fence 7, and the fourth step of constructing the safety fence 7 on the concrete product 6 A method for fixing the column is disclosed. In addition, the said code | symbol is a code | symbol described in patent document 1. FIG.

特開２００２−１４７０２７号公報JP 2002-147027 A

しかしながら、特許文献１に記載の安全柵の柱の固定工法では、コンクリート部材のアンカーに固定ボルトなどを固定するなどしてから、安全柵の柱を固定ボルトに螺設して安全柵を完成させるために、一度構築した安全柵を別のコンクリート部材に移設するときには、安全柵の手摺や柱を分解してから、別のコンクリート部材で改めて安全柵を構築する必要があり手間が掛かり過ぎていた。 However, in the method of fixing the pillar of the safety fence described in Patent Document 1, after fixing the fixing bolt or the like to the anchor of the concrete member, the pillar of the safety fence is screwed to the fixing bolt to complete the safety fence. Therefore, when moving the safety fence once constructed to another concrete member, it was necessary to disassemble the safety fence handrails and pillars and then build the safety fence again with another concrete member, which was too much work .

また、コンクリート部材のアンカーを利用して安全柵を構築し、その安全柵を分解せずに他のコンクリート部材に移設しようとしても、個々のコンクリート部材によってアンカーの取り付け間隔に多少の差異があるため、安全柵の柱の間隔の寸法調整する必要がありスムーズに構築した安全柵をそのまま移設することが困難であった。 In addition, even if a safety fence is constructed using concrete anchors and the safety fences are moved to other concrete parts without disassembling, there is a slight difference in anchor mounting intervals depending on the individual concrete parts. Therefore, it was necessary to adjust the distance between the pillars of the safety fence, and it was difficult to relocate the smoothly constructed safety fence as it was.

そこで、本発明は、一旦柱に手摺を横架して安全柵を構築してからでも、コンクリート部材の表面に設けられたアンカーなどの連結部材に構築された安全柵を固設することができ、さらに、個々のコンクリート部材における連結部材の間隔に誤差があっても構築された安全柵を任意の連結部材に固設することができる安全柵土台を提供することを課題とする。 Therefore, the present invention can fix a safety fence constructed on a connecting member such as an anchor provided on the surface of a concrete member even after a safety fence is constructed by horizontally placing a handrail on a pillar. Furthermore, it is an object to provide a safety fence base in which a constructed safety fence can be fixed to an arbitrary connection member even if there is an error in the interval between the connection members in the individual concrete members.

以下、本発明に係る安全柵土台に関する実施形態について詳しく説明する。 Hereinafter, the embodiment regarding the safety fence base which concerns on this invention is described in detail.

〔第一実施形態〕
図１に示すように、安全柵土台は、大きくコンクリートＣの連結部であるアンカーＡ１に固定する部材である固定具１と、安全柵３の支柱３１を止着する土台部２から構成される。そして、固定具１と土台部２は別個独立した部材となっている。 [First embodiment]
As shown in FIG. 1, the safety fence base is composed of a fixture 1 that is a member that is largely fixed to an anchor A <b> 1 that is a connecting part of concrete C, and a base part 2 that fixes a support 31 of the safety fence 3. . And the fixing tool 1 and the base part 2 are separate and independent members.

図１などに示すように、コンクリート部材Ｃは、予めコンクリート工場などで製造されてから種々の建築現場に輸送されてその建築現場で使用される固化されたコンクリートからなる部材である。そして、そのコンクリート部材Ｃの上部などの表面には、内側に向かって略半球状に窪んだ凹部を有し、その凹部の略半球状からなる面から、端部に鍔部を有するアンカーＡ１が突設されている。通常重量が大きいコンクリート部材Ｃをクレーンなどの機械で移動させるときに、このアンカーＡ１の鍔部にワイヤーなどを掛けてコンクリート部材Ｃを吊り上げて移動させる。 As shown in FIG. 1 and the like, the concrete member C is a member made of solidified concrete that is manufactured in advance in a concrete factory or the like and then transported to various construction sites and used at the construction site. And, on the surface such as the upper part of the concrete member C, an anchor A1 having a concave portion recessed in a substantially hemispherical shape toward the inside and having a flange portion at the end from the surface formed of the substantially hemispherical shape of the concave portion. Projected. When the concrete member C having a large weight is moved by a machine such as a crane, the concrete member C is lifted and moved by hanging a wire or the like on the collar portion of the anchor A1.

一般に、所定の建築物を製造するときには、同様の形状を有するコンクリート部材Ｃを複数組み合わせて製造するところ、一のコンクリート部材Ｃには、同一の表面に所定の間隔を開けて二つ以上のアンカーＡ１を有しているが、他のコンクリート部材ＣにおけるアンカーＡ１の間隔とはおおよそ同じであるが、コンクリート部材Ｃごとに多少の差異があり完全に同じでないことが多い。 Generally, when a predetermined building is manufactured, a plurality of concrete members C having the same shape are manufactured in combination, and one concrete member C has two or more anchors with a predetermined interval on the same surface. Although it has A1, although the distance of the anchor A1 in the other concrete member C is about the same, there are some differences for each concrete member C, and it is often not completely the same.

固定具１は、コンクリート部材ＣのアンカーＡ１に係止して固定される部材である。固定部１は、固定部１の基礎をなす基部１１と、基部１１の一端側に設けられアンカーＡ１の端部である鍔部と係止する係止部１２と、基部１１の他端側に設けられた螺子部１３を備えている。固定具１は土台部２と別体であるために、アンカーＡ１の大きさや形状に応じて、適切に取り付けることができるように種々の形状の係止部１２を有する多品種の固定具１を用意しておくことができる。このため、一の現場においてコンクリート部材ＣのアンカーＡ１の大きさや形状が異なる場合であっても、また、他の現場で使用しようとするきに先の現場とアンカーＡ１の大きさや形状が異なる場合であっても、土台部２の形状や大きさを変える必要がなく、固定具１のみを変更することにより簡便に作業することができる。 The fixing tool 1 is a member that is locked and fixed to the anchor A1 of the concrete member C. The fixing portion 1 includes a base portion 11 that forms the basis of the fixing portion 1, a locking portion 12 that is provided on one end side of the base portion 11 and that locks a collar portion that is an end portion of the anchor A <b> 1, and the other end side of the base portion 11. The provided screw part 13 is provided. Since the fixture 1 is separate from the base portion 2, the various types of fixtures 1 having variously shaped locking portions 12 so that they can be appropriately attached according to the size and shape of the anchor A1. Can be prepared. For this reason, even if the size and shape of the anchor A1 of the concrete member C are different at one site, or when the size and shape of the anchor A1 are different from the previous site when trying to use at another site Even so, it is not necessary to change the shape and size of the base portion 2, and it is possible to work simply by changing only the fixture 1.

本実施形態において、基部１１の外形は矩形状であるが、他の実施形態において、基部１１において、螺子部１３の軸方向に垂直な面で切断したときの最も長い差渡しの長さが、穿孔部２２の最も短い差渡しの長さよりも長い限りにおいて、五角形、六角形などの多角形、楕円形、略楕円形など種々の形状とすることができる。これにより、基部１１が穿孔部２２に緩嵌している状態で螺子部１３を締めたり緩めたりするときに、基部１１が螺子部１３の軸周りに回動したとしても、穿孔部２２の内周面にすぐに当接し、それ以上基部１１が回動することができず、基部１１が穿孔部２２に対して空回りしないため、螺子部１３を締めたり緩めたりする作業を容易に行うことができる。例えば、本実施形態において、矩形状の基部１１における最も長い差渡しの長さである基部１１の対角線の長さが、土台部２に穿設された矩形状の穿孔部２２の最も短い差渡しである穿孔部２２の短手方向の長さよりも長いため、基部１１が穿孔部２２に緩嵌している状態で螺子部１３を締めたり緩めたりするときに、基部１１の外周が穿孔部２２の内周に当接するので、螺子部１３を締めたり緩めたりする作業を容易に行うことができる。 In the present embodiment, the outer shape of the base portion 11 is rectangular, but in other embodiments, the length of the longest difference when the base portion 11 is cut by a plane perpendicular to the axial direction of the screw portion 13 is: As long as it is longer than the shortest passing length of the perforated portion 22, various shapes such as a polygon such as a pentagon and a hexagon, an ellipse, and a substantially ellipse can be used. Thereby, even when the base portion 11 is rotated around the axis of the screw portion 13 when the screw portion 13 is tightened or loosened while the base portion 11 is loosely fitted to the perforated portion 22, Since the base portion 11 cannot be rotated any further, and the base portion 11 does not rotate freely with respect to the perforated portion 22, the work of tightening or loosening the screw portion 13 can be easily performed. it can. For example, in the present embodiment, the length of the diagonal line of the base portion 11, which is the longest passing length in the rectangular base portion 11, is the shortest passing length of the rectangular perforated portion 22 drilled in the base portion 2. Therefore, when the screw portion 13 is tightened or loosened while the base portion 11 is loosely fitted to the perforated portion 22, the outer periphery of the base portion 11 is the perforated portion 22. Therefore, the work of tightening or loosening the screw portion 13 can be easily performed.

係止部１２は、基部１１の一端側である下方側に設けられており、コンクリート部材ＣのアンカーＡ１の端部と着脱可能に係止する部材である。図１及び図２に示すように、本実施形態において、係止部１２は、アンカーＡ１の端部に位置する鍔部に嵌合して係止する部材であり、アンカーＡ１の鍔部と嵌合して係止し、互いに対向する二本の爪部１２１を有している。これにより、アンカーＡ１に対して固定具１を取り付けて固定することができるとともに、固定具１を水平方向に移動させることにより二本の爪部１２１がアンカーＡ１の鍔部から外れることでアンカーＡ１から取り外すこともできる。なお、本実施形態において、係止部１２は、二本の爪部１２１を有するアンカーＡ１と着脱可能な部材であるが、他の実施例において、螺子を切られたアンカーの端部と螺着可能である螺子を有する部材とすることもできる。 The latching | locking part 12 is a member provided in the downward side which is the one end side of the base 11, and latches with the edge part of the anchor A1 of the concrete member C so that attachment or detachment is possible. As shown in FIG.1 and FIG.2, in this embodiment, the latching | locking part 12 is a member fitted and latched to the collar part located in the edge part of anchor A1, and it fits with the collar part of anchor A1. It has two claw portions 121 that are locked together and face each other. Thereby, the fixing tool 1 can be attached and fixed to the anchor A1, and the two claws 121 are disengaged from the collar part of the anchor A1 by moving the fixing tool 1 in the horizontal direction. It can also be removed from. In this embodiment, the locking portion 12 is a member that is detachable from the anchor A1 having the two claw portions 121. However, in another embodiment, the locking portion 12 is screwed to the end portion of the anchor that is threaded. It can also be a member having a screw that is possible.

螺子部１３は、基部１１の他端側、すなわち、係止部１２が存在する側とは反対側に位置しており、雌螺子部１３１と雄螺子部１３２から構成される部材である。螺子部１３により、アンカーＡ１に取り付けた固定具１を土台部２に対して動かないようにすることができ、ひいては土台部２の受け部２３に取り付けた安全柵３がコンクリー部材Ｃに固定することができる。 The screw portion 13 is located on the other end side of the base portion 11, that is, on the side opposite to the side where the locking portion 12 exists, and is a member composed of a female screw portion 131 and a male screw portion 132.

Since the base part 2 is a separate body from the fixture 1, even if the size and shape of the anchor A1 of the concrete member C are different at one site, they are also intended to be used at another site. Even if the size and shape of the anchor A1 are different from the previous site, the same thing can be used for the base part 2 only by changing only the fixture 1 attached to the anchor A1, so the shape can be changed depending on the site. The cost can be reduced without having to change

基礎２１は、固定具１とは別体であり、土台部２のベースとなる部材である。図１から図３などに示すように、本実施形態において、基礎２１は、矩形状の平板である。他の実施形態において、基礎２１は、多角形状、円形状、楕円形状などの板部材とすることができる。基礎２１は、土台部２の大きさや重量などの点から、板状の部材であることが好ましい。 The foundation 21 is a member that is a separate body from the fixture 1 and serves as a base of the base portion 2. As shown in FIGS. 1 to 3 and the like, in the present embodiment, the foundation 21 is a rectangular flat plate. In another embodiment, the foundation 21 can be a plate member having a polygonal shape, a circular shape, an elliptical shape, or the like. The base 21 is preferably a plate-like member from the viewpoint of the size and weight of the base portion 2.

穿孔部２２は、基礎２１の一部に基礎２１を貫通するように穿設された孔であり、この部分が、固定具１の基部１１との間に遊びがあり緩やかに嵌るよう、内周が基部１１の外周よりも大きく設けられている。穿孔部２２が基部１１と緩嵌することにより、図１０に示すように、固定具１と土台部２を固定したうえで、支柱３１に手摺３２を取り付けた安全柵３を土台部２に設けている状態において、図９に示すように、固定具１の係止部１２をコンクリート部材ＣのアンカーＡ１から取り外して、他のコンクリート部材ＣのアンカーＡ１に取り付けるときに、先の複数のアンカーＡ１の間隔と後の複数のアンカーＡ１の間隔が多少異なったとしても、適宜穿孔部２２における基部１１の位置を調節することにより、安全柵３を移設するたびに分解しなくともよいので速やかに作業を行うことができる。 The perforated part 22 is a hole formed so as to penetrate the base 21 in a part of the base 21, and this part has an inner periphery so that there is play between the base 11 of the fixture 1 and a loose fit. Is larger than the outer periphery of the base 11. When the perforated part 22 is loosely fitted to the base part 11, as shown in FIG. 10, the fixing tool 1 and the base part 2 are fixed, and a safety fence 3 with a handrail 32 attached to the support 31 is provided on the base part 2. 9, when the locking portion 12 of the fixture 1 is detached from the anchor A1 of the concrete member C and attached to the anchor A1 of the other concrete member C, as shown in FIG. Even if the interval of the anchors A1 and the interval of the plurality of anchors A1 are slightly different, it is not necessary to disassemble the safety fence 3 every time the safety fence 3 is moved by adjusting the position of the base 11 in the perforated part 22 as appropriate. It can be performed.

受け部２３は、基礎２１上に、穿孔部２２とは離れた位置に隣接して設けられ安全柵３の支柱３１を止着する部材である。受け部２３が、穿孔部２２と隣接して設けられていることにより、コンクリート部材ＣのアンカーＡ１上に支柱３１が位置しないように、すなわち、支柱３１の位置をアンカーＡ１の位置とずらすことができ、図１に示すように、よりコンクリート部材Ｃの淵に支柱３１を位置させられるようになるので、作業者がコンクリート部材Ｃ上で作業できるスペースをより広く確保することができる。本実施形態において、受け部２３は、中空の円筒状を有しており、円柱状の支柱３１の外周よりも大きく支柱３１を挿入して固定できる部材である。 The receiving portion 23 is a member that is provided adjacent to a position away from the perforated portion 22 on the foundation 21 and fastens the column 31 of the safety fence 3. Since the receiving portion 23 is provided adjacent to the perforated portion 22, the support 31 is not positioned on the anchor A1 of the concrete member C, that is, the position of the support 31 can be shifted from the position of the anchor A1. As shown in FIG. 1, the column 31 can be positioned more on the side of the concrete member C, so that a wider space for the operator to work on the concrete member C can be secured. In the present embodiment, the receiving portion 23 has a hollow cylindrical shape, and is a member that can be inserted and fixed larger than the outer periphery of the columnar column 31.

本実施形態において、受け部２３に対して支柱３１を挿入して固定するために、受け部２３の側面を貫通する固定螺子２４が設けられている。図１から図３などに示すように、固定螺子２４が受け部２３の側面に設けられた孔と螺合しながら受け部２３内に入り、固定螺子２４の先端が支柱３１に当接することにより、支柱３１を受け部３２に対して固定することができる。 In the present embodiment, a fixing screw 24 penetrating the side surface of the receiving portion 23 is provided in order to insert and fix the column 31 to the receiving portion 23. As shown in FIGS. 1 to 3 and the like, the fixing screw 24 enters the receiving portion 23 while being screwed into a hole provided on the side surface of the receiving portion 23, and the tip of the fixing screw 24 comes into contact with the column 31. The column 31 can be fixed to the receiving portion 32.

次に、本実施形態の安全柵土台の取り付け手順について説明する。 Next, the installation procedure of the safety fence base of this embodiment is demonstrated.

In the second embodiment, as shown in FIG. 11, the base portion 11 is an elongated columnar member that forms the basis of the fixed portion 1, and the locking portion 12 is threaded on the outer periphery at least at one end side of the base portion 11. It is the part that was made. And the latching | locking part 12 engages with the part of the internal thread of the edge part of the anchor A2 which is a connection part of the concrete member C, and latches so that attachment or detachment is possible. When the locking portion 12 has such a shape, it can be locked to the anchor according to the shape of the anchor. And the latching | locking part 12 is provided with the column-shaped overhang | projection part 123 larger than the diameter of the latching | locking part 12, and the latching | locking part 12 is screwed together with the part of the internal thread of the edge part of anchor A2. Since the overhang | projection part 123 will contact | abut with the collar part of the anchor A2, it can prevent that the latching | locking part 12 is screwed more than necessary. The head 14 has a rectangular parallelepiped shape.

そして、本実施形態の場合、図１０に示すような複数のアンカーに渡るように安全柵３を取り付けた場合、一度組み立てられた安全柵３を分解しなくとも、支柱３１を土台部２の受け部２３に取り付けたまま、固定具１を分解して土台部２から取り外すことにより、対応するアンカーから安全柵３を取り外すことにより移設することが可能となるので、安全柵３を都度分解することに比べれば簡便に他に移設することができる。 In the case of the present embodiment, when the safety fence 3 is attached so as to cross over a plurality of anchors as shown in FIG. 10, the support 31 is received by the base portion 2 without disassembling the safety fence 3 once assembled. Since it is possible to relocate by removing the safety fence 3 from the corresponding anchor by disassembling the fixing tool 1 and removing it from the base part 2 while being attached to the part 23, disassemble the safety fence 3 each time. Compared to, it can be easily relocated to others.

〔第三実施形態〕
図１３、図１４に示すように、安全柵土台の第三実施形態は、土台部２を第一実施形態と共通する。第一実施形態との相違は、固定具１における基部１１、係止部１２などの形状である。第三実施形態において、図１３に示すように、基部１１は、固定部１の基礎をなす細長い円柱状の部材であり、係止部１２は、基部１１の一端側に設けられ、内側に螺子が設けられた雌螺子を有する部分である。そして、係止部１２は、コンクリート部材Ｃの連結部であるアンカーＡ３の端部の雄螺子の部分と螺合して着脱可能に係止する。係止部１２がこのような形状を有することにより、アンカーの形状に応じてアンカーに対して係止することができる。また、頭部１４は、直方体形状を有している。 [Third embodiment]
As shown to FIG. 13, FIG. 14, 3rd embodiment of a safety fence base shares the base part 2 with 1st embodiment. The difference from the first embodiment is the shapes of the base portion 11 and the locking portion 12 in the fixture 1. In the third embodiment, as shown in FIG. 13, the base portion 11 is an elongated columnar member that forms the basis of the fixed portion 1, and the locking portion 12 is provided on one end side of the base portion 11, and has a screw on the inside. It is a part which has the female screw provided. And the latching | locking part 12 engages with the male screw part of the edge part of the anchor A3 which is a connection part of the concrete member C, and latches so that attachment or detachment is possible. When the locking portion 12 has such a shape, it can be locked to the anchor according to the shape of the anchor. The head 14 has a rectangular parallelepiped shape.

そして、第二実施形態と同様に、本実施形態の場合、図１０に示すような複数のアンカーに渡るように安全柵３を取り付けた場合、一度組み立てられた安全柵３を分解しなくとも、支柱３１を土台部２の受け部２３に取り付けたまま、固定具１を分解して土台部２から取り外すことにより、対応するアンカーから安全柵３を取り外すことにより移設することが可能となるので、安全柵３を都度分解することに比べれば簡便に他に移設することができる。 And similarly to the second embodiment, in the case of this embodiment, when the safety fence 3 is attached so as to cross over a plurality of anchors as shown in FIG. 10, even if the safety fence 3 once assembled is not disassembled, Since the support 31 is attached to the receiving portion 23 of the base portion 2, it is possible to relocate by removing the safety fence 3 from the corresponding anchor by disassembling and removing the fixture 1 from the base portion 2. Compared to disassembling the safety fence 3 each time, it can be easily moved to another location.

〔第四実施形態〕
図１５、図１６に示すように、安全柵土台の第四実施形態は、土台部２を第一実施形態と共通する。第一実施形態との相違は、固定具１における係止部１２などの形状である。第四実施形態において、係止部１２は、図１５に示すように、外形が矩形状の基部１１の一端側に設けられ外周に螺子を有する部材である。そして、係止部１２は、コンクリート部材Ｃに埋設され螺子を有する連結部である雌螺子穴Ａ４の端部側の雌螺子の部分と螺合して着脱可能に係止する。係止部１２がこのような形状を有することにより、雌螺子穴の形状に応じて雌螺子穴に対して係止することができる。そして、外形が矩形状の基部１１は、第一実施形態と同様に、基部１１が螺子部１３の軸周りに回動したとしても、穿孔部２２の内周面にすぐに当接し、それ以上基部１１が回動することができず、基部１１が穿孔部２２に対して空回りしないため、螺子部１３を締めたり緩めたりする作業を容易に行うことができるという効果を奏するとともに、第二実施形態の張出部１２３と同様に、形態係止部１２の径よりも大きいために、係止部１２を雌螺子穴Ａ４に螺合していくと基部１１が雌螺子穴Ａ４の端部と当接するので、必要以上に係止部１２を螺着させることを防止することができるという効果も奏する。また、頭部１４は、直方体形状を有している。 [Fourth embodiment]
As shown to FIG. 15, FIG. 16, 4th embodiment of a safety fence base shares the base part 2 with 1st embodiment. The difference from the first embodiment is the shape of the locking portion 12 and the like in the fixture 1. In 4th embodiment, the latching | locking part 12 is a member which is provided in the one end side of the base 11 with a rectangular external shape, and has a screw on the outer periphery, as shown in FIG. And the latching | locking part 12 engages with the part of the female screw of the end part side of female screw hole A4 which is a connection part which is embed | buried under the concrete member C, and has a screw | thread, and detachably latches. When the locking portion 12 has such a shape, it can be locked to the female screw hole according to the shape of the female screw hole. The base 11 having a rectangular outer shape immediately contacts the inner peripheral surface of the perforated portion 22 even when the base 11 rotates around the axis of the screw portion 13 as in the first embodiment. Since the base 11 cannot be rotated and the base 11 does not idle with respect to the perforated part 22, it is possible to easily perform the work of tightening or loosening the screw part 13, and the second embodiment. Similarly to the overhanging portion 123 of the form, since the diameter of the form locking portion 12 is larger, when the locking portion 12 is screwed into the female screw hole A4, the base 11 is connected to the end of the female screw hole A4. Since it contacts, there also exists an effect that it can prevent screwing the latching | locking part 12 more than necessary. The head 14 has a rectangular parallelepiped shape.

そして、第二実施形態及び第三実施形態と同様に、本実施形態の場合、図１０に示すような複数のアンカーに渡るように安全柵３を取り付けた場合、一度組み立てられた安全柵３を分解しなくとも、支柱３１を土台部２の受け部２３に取り付けたまま、固定具１を分解して土台部２から取り外すことにより、対応する雌螺子穴から安全柵３を取り外すことにより移設することが可能となるので、安全柵３を都度分解することに比べれば簡便に他に移設することができる。 And like 2nd embodiment and 3rd embodiment, in the case of this embodiment, when safety fence 3 is attached so that it may cross over a plurality of anchors as shown in Drawing 10, safety fence 3 once assembled Even if it is not disassembled, it is moved by removing the safety fence 3 from the corresponding female screw hole by disassembling the fixture 1 and removing it from the base portion 2 with the support column 31 attached to the receiving portion 23 of the base portion 2. Therefore, compared with disassembling the safety fence 3 each time, it can be easily relocated.
