In order to install the cubicle 94 on a ground surface, a basement, etc., a metal box 95 is installed on a concrete foundation 93. That is, as shown in FIG. 16, a large number of anchor bolts (hereinafter simply referred to as “bolts”) B are embedded in the concrete foundation 93 corresponding to the outer peripheral shape of the box. The box 95 is fixedly installed on the concrete foundation 93 by inserting each projecting end Ba into the substrate 91 of the box 95 and screwing a nut N to the projecting end Ba of the bolt B. .

キュービクル94を構成するボックス95を上記のようにして地上面等に据え付ける構造において、多数本のボルトBが当該ボックス95の外周縁の外側に配置されるのを防止するために、当該ボックス95の下端部である基板91の外周部には、アンダーカット状空間96が形成されていて、当該空間96に各ボルトBの突出端部Baが露出しない構造になっている。   In the structure in which the box 95 constituting the cubicle 94 is installed on the ground surface or the like as described above, in order to prevent the large number of bolts B from being arranged outside the outer peripheral edge of the box 95, An undercut space 96 is formed on the outer peripheral portion of the substrate 91 which is the lower end portion, and the protruding end portion Ba of each bolt B is not exposed in the space 96.

一方、ナットNが螺着された各ボルトBの突出端部Baは、腐食防止のために、その全体をカバー体で覆っている。このカバー体の一つとして、特許文献1に開示のものが知られているが、当該カバー体の全体形状は、上端面が閉塞された一体筒状であって、ボルトBの突出端部Baの直上から、当該ボルトBの軸方向にカバー体を移動させて、当該ボルトBの突出端部Ba及びナットNを覆う構成であるため、上記したアンダーカット状空間96に配置されたボルトBの突出端部Baを直上から覆うことは、できなかった。   On the other hand, the projecting end Ba of each bolt B to which the nut N is screwed is entirely covered with a cover body to prevent corrosion. Although one disclosed in Patent Document 1 is known as one of the cover bodies, the overall shape of the cover body is an integral cylindrical shape whose upper end face is closed, and the projecting end portion Ba of the bolt B is Since the cover is moved in the axial direction of the bolt B from immediately above to cover the projecting end Ba of the bolt B and the nut N, the bolt B disposed in the above-described undercut-like space 96 is It was not possible to cover the projecting end Ba from directly above.

That is, as shown in FIGS. 5 and 6, the female screw piece E has a plurality of types having different outer diameters in the flat surfaces 32, 33a (33b) which are back to back of the rectangular block shaped piece main body 31. Recesses 34 and 35 having semicircular cross-sections different in size corresponding to the bolt B are formed along the cylinder axial direction Q in a state of being incorporated into the split cover bodies C 11 and C 12 , First and second partial female threads F 1 and F 2 having a central angle of approximately 180 ° corresponding to a plurality of types of bolts B having different outer diameters are formed on the inner peripheral surfaces of the concave portions 34 and 35 respectively. There is. Internally threaded piece body E is partially threaded onto the projecting end portion Ba of the bolt B, and the state covering the projecting end Ba with the cover member C 1, the cover member C 1 is the projecting end portion Ba Since it is sufficient if it is possible to prevent it from coming off from each other, each partial female thread F 1 and F 2 formed in each recess 34 and 35 of the piece main body 31 is screwed to all threads of the projecting end Ba of the bolt B. As it does not need to be worn, it is a partial internal thread. Further, as described later, since the female screw piece E may be used by being turned upside down, each of the first and second end portions along the cylinder axial direction Q in each of the concave portions 34 and 35 may be used. The partial female threads F 1 and F 2 are formed, and one of them is screwed to the projecting end Ba of the bolt B in a partially locked state. In FIG. 6 (b), F 1 a and F 2 a indicate thread portions of the first and second partial female screw portions F 1 and F 2 , respectively.

駒体本体31の前記各凹部34,35が形成された平面32,33a(33b)に対して直交して背中合わせとなる各平面36,37には、前記各分割カバー体C11,C12の内面に対向して形成された各嵌入組付け溝23a,23bに嵌入されて、当該駒体本体31を前記各分割カバー体C11,C12の内部に一体に組み付けるための複数の嵌入突部38が、当該各分割カバー体C11,C12に対する駒体本体31の嵌入方向Rと直交する方向に沿って一定ピッチSeをおいて当該嵌入方向Rに沿って形成されている。各嵌入突部38の嵌入方向Rに沿った上下面は、当該嵌入方向Rに沿った両端から中央に向けて僅かに漸次厚肉となるように形成されることで、分割カバー体C11,C12に対して圧入状態で嵌入され、背中合わせとなった各平面36,37にそれぞれ形成されている複数(実施例では3個)の嵌入突部38の前記筒軸方向Qに沿った配置位置は、同一である。なお、前記嵌入突部38の嵌入方向Rに沿って両端の肉厚Teは、相上下する嵌入突部38の間に形成される嵌入溝39の嵌入方向に沿った基端の内幅Weに等しく、各嵌入溝39のピッチ(間隔)は、嵌入突部38及び嵌入溝39のピッチSeの半分と同一である。この結果、(Te=We=Se/2)の関係が成立する。なお、駒体本体31の残りの背中合わせに対向する2面は、一対の雌ねじ駒体Eの対面保持姿勢の変更に、いずれか一方が上面となって、他方が下面となるので、2面を上下面41と総称する。 The respective planes 36 and 37 to be back to back perpendicular to the plane the recesses 34 and 35 are formed 32,33a (33b) of the frame body 31, the respective divided cover body C 11, C 12 A plurality of fitting projections which are fitted into the fitting assembly grooves 23a and 23b formed to face the inner surface and integrally assemble the piece main body 31 into the interiors of the respective divided cover bodies C 11 and C 12 38 are formed along the insertion direction R at a constant pitch Se along the direction orthogonal to the insertion direction R of the piece main body 31 with respect to the divided cover bodies C 11 and C 12 . The upper and lower surfaces along the insertion direction R of each insertion projection 38 are formed so as to become gradually thicker from the both ends along the insertion direction R toward the center, thereby the split cover body C 11 , The arrangement position along the cylinder axial direction Q of the plurality (three in the embodiment) of the insertion projections 38 formed on the flat surfaces 36 and 37 that are inserted in a press-fit state with respect to C 12 and are back to back. Are identical. The thickness Te of both ends along the insertion direction R of the insertion projection 38 is the inner width We of the base end along the insertion direction of the insertion groove 39 formed between the insertion projections 38 moving up and down. Equally, the pitch (distance) of each insertion groove 39 is equal to half of the pitch Se of the insertion projection 38 and the insertion groove 39. As a result, the relationship of (Te = We = Se / 2) is established. The other two surfaces facing the back-to-back of the piece main body 31 have two surfaces, one of which is the upper surface and the other is the lower surface for changing the facing holding posture of the pair of female screw pieces E. Collectively referred to as upper and lower surfaces 41.

また、図21の表に、複数のメートルねじ及びウイットねじのピッチ、外径、有効径及び谷径が示されている。第1部分雌ねじ部F1 は、M10(外径10mmメートルねじ)のボルトB1 と、M12(外径12mmメートルねじ)のボルトB2 と、W3/8 (1インチに16のねじ山を有するウイットねじ)のボルトB4 と、W1/2 (1インチに12のねじ山を有するウイットねじ)のボルトB5 とに適用され、第2部分雌ねじ部F2 は、M16(外径16mmメートルねじ)のボルトB3 と、W5/8 (1インチに11のねじ山を有するウイットねじ)のボルトB6 に適用される。なお、第1及び第2の各部分雌ねじ部F1 ,F2 の螺着の対象として、一般使用されるメートルねじのみならず、ウイットねじも含めたのは、ウイットねじは、JISのねじ規格では廃止されているが、特に建築業界で使用され続け、その建築物又は建造物が現在でも使用されている結果、ウイットねじが残存していることによる。 Also, in the table of FIG. 21, the pitch, outer diameter, effective diameter and valley diameter of a plurality of metric screws and Whitscrews are shown. The first part the internal thread portion F 1 includes a bolt B 1 of M10 (outer diameter 10mm metric threads), the bolt B 2 of M12 (outer diameter 12mm metric threads), a 16 threads of the W3 / 8 (1 inches the bolt B 4 of Whitworth screw), is applied to the bolt B 5 of Whitworth screw) having 12 threads of the W1 / 2 (1 inch second portion internally threaded portion F 2 are, M16 (outer diameter 16mm metric thread the bolt B 3 of), is applied to the bolt B 6 of Whitworth screw) with a screw thread 11 to W5 / 8 (1 inch. In addition, not only the metric screw generally used as a target for screwing of the first and second partial female screw parts F 1 and F 2 , but also the whit screw is included, the whit screw is a JIS screw standard In particular, it continues to be used in the construction industry, and as a result of the use of the building or structure, the Whitscrew remains as a result.

このように、第1部分雌ねじ部F1 は、第2部分雌ねじ部F2 に比較して、部分螺着対象のボルトの外径差が大きい。換言すると、一種類の第1部分雌ねじ部F1 により、外径差の大きな複数種類のボルトに対して部分螺着させる必要がある。これを解決するために、第1部分雌ねじ部F1 が対向配置される一対の雌ねじ駒体Eの対向間隔を広くすることで、M12のボルトB2 とW1/2 のボルトB5 に部分螺着可能となり、その実現手段として、駒体本体31の上下面41を反転させた状態において、各駒体本体31の対向方向に沿って配置位置を変更可能な構成を採用した。具体的には、第2部分雌ねじ部F2 が形成されることで、その幅方向の両端部に残存する各平面33a,33bを、前記嵌入方向Rに沿って段差43を設けることで、当該嵌入方向Rに沿って突出した平面33bの部分に、前記各分割カバー体C11,C12にぞれぞれ形成された嵌合溝24a,24bに嵌合される嵌合突部44を設けることで、一対の雌ねじ駒体Eの対向方向に沿った間隔を広くできるようにしてある。 Thus, the first partial female screw portion F 1, compared to the second portion internally threaded portion F 2, a large outer diameter difference portion screwing subject of the bolt. In other words, the first part the internal thread portion F 1 of one kind, it is necessary to partially screwed for large plurality of types of bolts outer diameter difference. To solve this, since the first partial female screw portion F 1 is wider opposing gap between the pair of internally threaded piece body E is opposed, part threaded on the bolt B 5 of the bolt B 2 and W1 / 2 of M12 As the realization means, a configuration is adopted in which the arrangement position can be changed along the opposing direction of each piece main body 31 in a state where the upper and lower surfaces 41 of the piece main body 31 are reversed. Specifically, by forming the second partial female screw portion F 2 , the flat surfaces 33 a and 33 b remaining at both end portions in the width direction thereof are provided with the step 43 along the insertion direction R, In the portion of the flat surface 33b which protrudes along the insertion direction R, the fitting protrusion 44 fitted in the fitting grooves 24a and 24b respectively formed on the divided cover bodies C 11 and C 12 is provided. Thus, the distance along the opposing direction of the pair of female screw pieces E can be increased.

カバー体C1 を構成する各分割カバー体C11,C12に、上記した一対の雌ねじ駒体Eを、第1及び第2の各部分雌ねじ部F1 ,F2 のいずれか一方を対向状態で組付け可能とするために、各分割カバー体C11,C12の内周面には、筒軸方向Qに沿って前記駒体本体31の背中合わせの各平面36,37にそれぞれ形成された各嵌入突部38を嵌入するための複数の嵌入組付け溝23a,23bが、当該嵌入突部38の形成ピッチSeと同一のピッチScをおいて、分割カバー体C11,C12の直径方向に対向してそれぞれ形成されている。即ち、図1〜図3、特に、図3に詳細に図示されているように、複数の嵌入組付け溝23a,23bを形成するために、複数の側板体25a,25bが前記ピッチScでもって、各分割カバー体C11,C12の内周面に対向して配置され、相上下する各側板体25a,25bの間に前記嵌入組付け溝23a,23bが形成される。各分割カバー体C11,C12に形成される各嵌入組付け溝23a,23bの内幅Wcは、各側板体25a,25bの肉厚(板厚)Tcと同一であって、前記ピッチScの半分である。よって、(Tc=Wc=Sc/2)の関係が成立し、雌ねじ駒体Eとの関係では、(Tc=Te,Wc=We,Sc=Se)となる。 Each of the divided cover bodies C 11 and C 12 constituting the cover body C 1 is in a state in which the above-mentioned pair of female screw pieces E are opposed to one of the first and second partial female screw parts F 1 and F 2 In order to enable assembly at the same time, the inner peripheral surfaces of the divided cover bodies C 11 and C 12 are formed on the back-to-back flat surfaces 36 and 37 of the block body main body 31 along the cylinder axis direction Q, respectively.

そして、上記したカバー体C1 と一対一組の雌ねじ駒体Eを使用して、ボルトBの突出端部Baを、当該突出端部Baに対してカバー体C1 が軸方向にずれない状態で覆うには、以下のようにして行う。なお、図10は、一対の雌ねじ駒体Eの保持姿勢を模式的に説明するための図であるため、各分割カバー体C11,C12の側板体25a,25b及び奥板体26a,26bは、簡略表示してある。一対一組の雌ねじ駒体Eは、配置により、ボルトBの大きさに応じた計3種類の対向保持姿勢を選択できる。即ち、図10(a)のように、各駒体本体31の第1部分雌ねじ部F1 を対向させ、しかも背面側の平面33bの部分に形成された嵌合突部44が、各分割カバー体C11,C12の嵌合溝24a,24bに嵌合されるように配置すると、外径12mmのメートルねじのボルトB2 (M12)及び1インチに12のねじ山を有するウイットねじのボルトB5 (W1/2 )の双方に対して部分螺着可能となる。また、上記した第1姿勢から、第1部分雌ねじ部F1 が対面した状態を維持して、各雌ねじ駒体Eの上下面41を反転させると、図10(b)に示されるように、駒体本体31の背面側の平面33bが、分割カバー体C11,C12の奥板体26a,26bの前端面26a1,26b1に当接して、前記第1姿勢に対して各駒体本体31が近接することで、外径10mmのメートルねじのボルトB1 (M10)及び1インチに16のねじ山を有するウイットねじのボルトB4 (W3/8 )の双方に対して部分螺着可能な第2姿勢となる。更に、第1及び第2の各姿勢から、各駒体本体31の対面を反転させると、図10(c)に示されるように、駒体本体31の平面32が、各分割カバー体C11,C12の奥板体26a,26bの前端面26a1,26b1に当接することで、各第2部分雌ねじ部F2 が対面して、外径16mmのメートルねじのボルトB3 (M16)及び1インチに11のねじ山を有するウイットねじのボルトB6 (W5/8 )の双方に対して部分螺着可能な第3姿勢となる。 Then, using the above-described cover member C 1 and the pairs of internally threaded piece body E, the projecting end portion Ba of the bolt B, the cover body C 1 with respect to the projecting end portion Ba is not displaced in the axial direction state To cover with, do as follows. 10 is a view for schematically explaining the holding posture of the pair of female screw pieces E, the side plates 25a and 25b and the rear plates 26a and 26b of the divided cover members C 11 and C 12 are illustrated. Is simplified. Depending on the arrangement, a total of three types of opposing holding postures can be selected according to the size of the bolt B depending on the arrangement. That is, as shown in FIG. 10 (a), the first partial female screw portion F 1 are opposed to the fitting projection 44 which moreover is formed in a portion of the back side of the plane 33b, of each frame body 31, the split covers body C 11, C 12 of the fitting groove 24a, when disposed as fitted to 24b, the Whitworth screw with a bolt B 2 (M12) and 12 threads of one inch metric thread outer diameter 12mm bolt Partial screwing is possible to both of B 5 (W1 / 2). Further, from the first posture described above, while maintaining the state in which the first partial female screw portion F 1 is facing, when reversing the upper and lower surfaces 41 of each internal thread piece body E, as shown in FIG. 10 (b), rear side of the plane 33b of the frame body 31, the back plate member 26a of the split cover body C 11, C 12, abuts against the front end face 26a 1, 26b 1 of 26b, each frame member to the first position The proximity of the main body 31 results in partial screw attachment to both metric screw bolt B 1 (M10) with an outer diameter of 10 mm and to bolt screw B 4 (W3 / 8) with 16 threads per inch. It becomes a possible second attitude. Furthermore, when the facing of each piece main body 31 is reversed from the first and second postures, as shown in FIG. 10C, the flat surface 32 of the piece main body 31 is divided into each divided cover C 11 , C 12 abuts on the front end faces 26a 1 , 26b 1 of the back plates 26a, 26b so that the respective second part female screw parts F 2 face each other and a bolt B 3 (M16) of a metric screw having an outer diameter of 16 mm And a third position in which partial screwing is possible to both of the bolts B 6 (W5 / 8) of the Whitscrew having 11 threads per inch.

このため、カバー体C1 で覆う対象のボルトBの大きさ及び当該ボルトBの突出端部Baの突出長に対応して、上記した第1〜第3の保持姿勢のいずれかを選択して、一対一組の各雌ねじ駒体Eを各分割カバー体C11,C12の内部に組み付けて収容する。即ち、第1〜第3の保持姿勢からボルトBの突出端部Baに対応した保持姿勢を選択して、当該保持姿勢となるように、ヒンジ連結された各分割カバー体C11,C12の内部に一体に組み付ける。図7〜図12に示される例は、M12のメートルねじのボルトB2 (M12)であって、当該ボルトB2 の突出端部B2aにナットNが二重に螺着され、雌ねじ駒体Eの下端が上段のナットNに最も近接するような位置に、各分割カバー体C11,C12に対して各雌ねじ駒体Eが組み付けられる。このため、各雌ねじ駒体Eの駒体本体31の両側面の各平面36,37に設けられた計3段(3個)の嵌入突部38のうち、上段から起算して2個の嵌入突部38が、各分割カバー体C11,C12に設けられた嵌入組付け溝23a,23bに嵌入されることで、各分割カバー体C11,C12の内部に、それぞれ雌ねじ駒体Eが組み付けられている。 Therefore, in accordance with the size of the bolt B to be covered by the cover C 1 and the projection length of the projection end Ba of the bolt B, one of the first to third holding postures is selected. A pair of female screw pieces E are assembled and housed inside the divided cover bodies C 11 and C 12 . That is, the holding posture corresponding to the projecting end Ba of the bolt B is selected from the first to third holding postures, and the divided cover bodies C 11 and C 12 are hinged so as to be the holding posture. Assemble integrally inside. Example shown in FIGS. 7 to 12, a bolt B 2 metric screws M12 (M12), a nut N is screwed to double the projecting end B 2 a of the bolt B 2, the internal thread piece Each female screw piece E is assembled to each of the divided cover bodies C 11 and C 12 at a position where the lower end of the body E is closest to the nut N on the upper stage. For this reason, of the total of three stages (three pieces) of the fitting projections 38 provided on the flat surfaces 36 and 37 of the both side surfaces of the piece main body 31 of each female screw piece E, two from the upper stage projections 38, fitting assembly grooves 23a provided in each of the divided cover body C 11, C 12, by being fitted into 23b, inside each divided cover body C 11, C 12, respectively internally threaded piece body E Is assembled.

そして、基板面91aから突出したボルトBの突出端部Ba及び当該突出端部Baに螺着されたナットNをカバー体C1 で覆うには、以下のようにして行う。即ち、図11(a)に示されるように、基板面91aの上面において、ヒンジ連結された各分割カバー体C11,C12を最大に開いておき、この状態で、ヒンジ連結された各分割カバー体C11,C12の下端面21,22を基板面91aの上面を摺動させて、図11(b)に示されるように、一方の分割カバー体C12の収容開口10から内部に、前記ボルトBの突出端部Baが雌ねじ駒体Eの第1部分雌ねじ部F1 が形成された凹部34に収容されるようにして、前記ボルトBの突出端部Ba及びナットNを、当該分割カバー体C11の内部に収容させる。この状態で、図11(c)に示されるように、ボルトBの突出端部Ba及びナットの軸方向に沿った半分を収容している一方の分割カバー体C12に対して他方の分割カバー体C11をヒンジ回動させると、分割カバー体C12の分割周壁部1bにおける収容開口10に臨んだ部分に形成された上下一対の各係止突起11と、他方の分割カバー体C11の各被係止孔15とが互いに係止されて、各分割カバー体C11,C12が一体に組み付けられる。この状態では、図11(d)及び図12に示されるように、各分割カバー体C11,C12の分割周壁部1a,1bの第1開口端面3,4どうし、第2開口端面7,8どうし、及び分割天壁部2a,2bの第3開口端面16,17どうしが、それぞれ互いに重合壁(二重壁)構造で密着することで、周壁部1及び天壁部2の各切割り開口状の部分がシール状態で密着される。なお、図11(d)において、45,46は、それぞれカバー体C1 の周壁部1及び天壁部2の切割り線を示す。なお、図12において、91は、コンクリート基礎93の上面に配置された基板を示す。 The protruding end Ba of the bolt B protruding from the substrate surface 91 a and the nut N screwed to the protruding end Ba are covered with the cover C 1 as follows. That is, as shown in FIG. 11A, on the upper surface of the substrate surface 91a, the hinged connected split cover bodies C 11 and C 12 are maximally opened, and in this state, each hinged connected splits The lower end faces 21 and 22 of the cover members C 11 and C 12 are slid on the upper surface of the substrate surface 91 a, and as shown in FIG. 11 (b), from the accommodation opening 10 of one split cover member C 12 to the inside The protruding end Ba of the bolt B and the nut N are accommodated such that the protruding end Ba of the bolt B is accommodated in the recess 34 in which the first partial female thread F 1 of the female screw piece E is formed. It is accommodated in the split cover body C 11. In this state, as shown in FIG. 11 (c), the other split cover for one split cover body C 12 accommodating the projecting end Ba of the bolt B and the half along the axial direction of the nut. When the body C 11 to hinge pivot, and the engaging projections 11 of the upper and lower formed facing it part housing opening 10 in the dividing wall portion 1b of the split cover body C 12, the other split cover body C 11 The respective locking holes 15 are locked to each other, and the divided cover bodies C 11 and C 12 are assembled integrally. In this state, as shown in FIG. 11D and FIG. 12, the first opening end faces 3 and 4 of the divided peripheral wall portions 1a and 1b of the divided cover bodies C 11 and C 12 and the second opening end face 7, The respective splits of the peripheral wall portion 1 and the top wall portion 2 are brought into close contact with each other by bringing the third opening end faces 16 and 17 of the divided top wall portions 2a and 2b into close contact with each other with a double wall structure. The open part is in close contact in a sealed manner. Incidentally, in FIG. 11 (d), 45, 46, respectively show a cut-split line of the peripheral wall 1 and a top wall 2 of the cover body C 1. In FIG. 12, reference numeral 91 denotes a substrate disposed on the upper surface of the concrete foundation 93.

また、各駒体本体31の凹部34に形成された上下の各部分雌ねじ部F1 のうち下方の部分雌ねじ部F1 が、ボルトBの突出端部Baの雄ねじ部に部分螺着されるため、当該ボルトBの突出端部Baに対してカバー体C1 が外れることはない。更に、分割カバー体C12の分割周壁部1bに形成された閉塞板部28を除去して形成される充填開口27から、カバー体C1 の下半部に形成される内部空間に充填材92を充填すると、ボルトBの突出端部Ba及び当該突出端部Baに螺着されたナットNの腐食を一層確実に防止できる。なお、充填材92の充填の必要がない場合には、充填開口27は,閉塞板部28で閉塞されたままにしておけばよい。 Further, since the partial female screw portion F 1 of the lower of the respective partial female screw portion F 1 of the top and bottom formed in the recess 34 of each frame body 31 is partially screwed to the male screw portion of the projecting end portion Ba of the bolt B , it will not come off the cover body C 1 with respect to the projecting end portion Ba of the bolt B. Furthermore, the filling opening 27 formed the closing plate part 28 formed in the dividing wall portion 1b of the split cover body C 12 is removed, filled in an inner space formed in the lower half of the cover body C 1 material 92 The corrosion of the projecting end Ba of the bolt B and the nut N screwed to the projecting end Ba can be more reliably prevented. When the filling material 92 does not need to be filled, the filling opening 27 may be kept closed by the closing plate portion 28.

このため、図16及び図17に示されるようなキュービクル94を構成する金属製ボックス95の下端部の周縁には、アンダーカット状空間96が形成され、コンクリート基礎93に埋設されたボルトBの上端部は、前記アンダーカット状空間96に突出するように施工される。しかし、本発明に係るカバー体C1 によれば、前記ボルトBの突出端部Baは、その側方から分割カバー体C11,C12の内部に収容できるため、ボルトBの突出端部Baの直上に近い部分に、アンダーカット状空間96の天面が存在していて、当該ボルトBの突出端部Baの直上からは、カバー体を覆い被せることが不能な場合でも、当該突出端部Baを覆うことができる。 For this reason, an undercut-like space 96 is formed on the periphery of the lower end portion of the metal box 95 constituting the cubicle 94 as shown in FIGS. 16 and 17, and the upper end of the bolt B embedded in the concrete foundation 93. The portion is constructed to project into the undercut space 96.

また、特許請求の範囲の各請求項で使用されている用語との関係は、請求項1に使用の「開口」及び「開口閉塞部」は、実施例1においては、ヒンジ連結された一対の分割カバー体C11,C12の二分割された各分割周壁部1a,1bの開閉によりそれぞれ形成されるので、当該各分割周壁部1a,1bが対応する機能を果たしている。請求項3の「切割り開口」に関しても、ヒンジ連結構造になっている各分割周壁部1a,1bが開くことで収容開口10が形成されるので、当該収容開口10は、請求項3の「切割り開口」に相当する。 Also, in relation to terms used in each claim in the claims, “opening” and “opening closure” used in claim 1 are, in Example 1, a pair of hinged members. Since the split cover bodies C 11 and C 12 are respectively formed by opening and closing the split peripheral wall portions 1 a and 1 b divided into two, the respective split peripheral wall portions 1 a and 1 b fulfill the corresponding functions. Also with regard to the "split opening" of claim 3, the accommodation opening 10 is formed by opening the divided peripheral wall portions 1a and 1b having the hinge connection structure. It corresponds to "split opening".

また、上記した各カバー体C1 ,C2 は、アンダーカット状空間96に突出されたボルトBの突出端部Baのように、当該突出端部Baの直上からカバー体を覆い被せられない場合に、特に有効であるが、各カバー体C1 ,C2 は、当該突出端部Baが全方向に開放された空間部に突出しているような場面での使用も可能であり、各カバー体C1 ,C2 の内部に収容配置した雌ねじ駒体Eが当該突出端部Baに部分螺着されている場合には、ボルトBの突出端部Baに対して各カバー体C1 ,C2 が外れない利点もある。 Further, as in the case of the projecting end Ba of the bolt B projected into the undercut-like space 96, each of the cover bodies C 1 and C 2 described above can not cover the cover body from directly above the projecting end Ba. In particular, each cover body C 1 and C 2 can also be used in a situation where the projecting end portion Ba protrudes into a space opened in all directions, and each cover body is particularly effective. When the female screw piece E housed and arranged inside C 1 and C 2 is partially screwed to the projecting end Ba, the cover body C 1 and C 2 with respect to the projecting end Ba of the bolt B There is also an advantage that

また、ボルトBの突出端部Baの突出長が短い場合には、雌ねじ駒体Eの最上段の嵌入突部38を、各分割カバー体C11,C12(C21,C22 )の下段の嵌入組付け溝23a,23bに嵌入させて、各分割カバー体C11,C12(C21,C22 )に対する雌ねじ駒体Eの配置位置を下げることで、対応できる。 When the projection length of the projection end Ba of the bolt B is short, the insertion projection 38 of the uppermost step of the female screw piece E is used as the lower end of each of the divided cover bodies C 11 and C 12 (C 21 and C 22 ). This can be coped with by inserting the female screw piece body E with respect to the divided cover bodies C 11 and C 12 (C 21 and C 22 ) by inserting them into the fitting assembling grooves 23 a and 23 b.
