また、吊治具を物品に係合する作業及び物品から取り外す作業がきわめて簡単であるので、物品を吊り上げて移動する作業が容易となる。
本発明の舗装板ブロックの敷設方法は、吊上孔が吊治具とブロックを係合する役割と、ブロックをアンカーで地面に固定する役割を兼ねるので、ブロックにインサートを埋め込むための手間と費用が不要となり、きわめて合理的である。さらに、吊治具をブロックに係合する作業及びブロックから取り外す作業がきわめて簡単であるので、物品を吊り上げて敷設する作業が容易となる。 Since the lifting jig and the method for lifting an article of the present invention do not need to embed a lifting insert in the article in advance, the labor and cost for embedding the insert are not required.
In addition, since the operation of engaging the lifting jig with the article and the operation of removing it from the article are very simple, the operation of lifting and moving the article becomes easy.
In the method for laying a paving board block according to the present invention, the lifting hole serves both to engage the lifting jig and the block and to fix the block to the ground with an anchor. Is no longer necessary and is extremely reasonable. Furthermore, since the work of engaging the lifting jig with the block and the work of removing it from the block are very simple, the work of lifting and laying the article becomes easy.

図１〜３に示す実施例の吊治具Ａは、２本の棒状部材１、２を有する。棒状部材１、２は断面が四辺形（円形などでもよい）の金属棒で、それぞれ上部に開口１３、２３が形成された円環部１２、２２を有し、中間部に軸受孔１６、２６が形成された軸受部１５、２５を有し、下部が折り曲げ部１４、２４となっている。
円環部１２、２２は棒状部材の上部を円環状に曲げて形成され、軸受部１５、２５はＵ字形の金属部材を溶接固定して形成され、開口１３、２３と軸受孔１６、２６の向きは、それぞれ直角となっている。
棒状部材１、２は、軸受部１５、２５において所定間隔（ボルト３０の軸径よりやや大きい間隔）を隔てて対向して配置され（図２）、それぞれの軸受孔１６、２６に軸であるボルト３０を挿通し、ナット３１で締め付け一体化している（図１）。符号３２はワッシャーである。棒状部材１、２は、ボルト３０を軸として回動自在となっているので、棒状部材１、２は、その上端部又は下端部が相互に接触するまでの範囲で回動自在である（図２）。 1-3 has two rod-shaped members 1 and 2 in the embodiment shown in FIGS. The rod-shaped members 1 and 2 are metal bars having a quadrilateral cross section (may be circular or the like), and have annular portions 12 and 22 having openings 13 and 23 formed in the upper portions thereof, respectively, and bearing holes 16 and 26 in the intermediate portions. Are formed, and the lower portions are bent portions 14 and 24.
The annular portions 12 and 22 are formed by bending the upper portion of the rod-like member into an annular shape, and the bearing portions 15 and 25 are formed by welding and fixing a U-shaped metal member, and the openings 13 and 23 and the bearing holes 16 and 26 are formed. Each direction is a right angle.
The rod-shaped members 1 and 2 are arranged to face each other at a predetermined interval (slightly larger than the shaft diameter of the bolt 30) in the bearing portions 15 and 25 (FIG. 2), and are shafts in the respective bearing holes 16 and 26. Bolts 30 are inserted and tightened and integrated with nuts 31 (FIG. 1). Reference numeral 32 denotes a washer. Since the rod-shaped members 1 and 2 are rotatable about the bolt 30, the rod-shaped members 1 and 2 are rotatable within a range until the upper end portions or the lower end portions thereof contact each other (see FIG. 2).

棒状部材１、２の折曲部１４、２４は、開口１３、２３の向いている方向（矢印Ｘ方向）で、かつ吊治具Ａの外側方向に折り曲げられている。折り曲げ角度は、図７に示す物品を吊り上げた状態において、吊上孔４３に密着する角度（約１０°）となっている。
なお、折曲部は必ずしも必要ではなく、吊上孔の径が大きく、棒状部材１、２の軸受部における間隔を広くした場合は、折曲部を設けなくとも棒状部材の下部を吊上孔に密着できる。 The bent portions 14 and 24 of the rod-like members 1 and 2 are bent in the direction (the arrow X direction) in which the openings 13 and 23 are directed and in the outward direction of the hanging jig A. The bending angle is an angle (about 10 °) in close contact with the lifting hole 43 when the article shown in FIG. 7 is lifted.
It should be noted that the bent portion is not necessarily required. When the diameter of the lifting hole is large and the interval between the bearing portions of the rod-shaped members 1 and 2 is widened, the lower portion of the rod-shaped member is not formed in the lifting hole without providing the bent portion. It can adhere to.

次に、吊治具Ａを用いた物品の吊り上げ方法を、舗装板ブロックを敷設する場合を例にして説明する。
舗装板４は、図１１に示すように、３枚の鉄筋コンクリート製の舗装板ブロック４１、４２、４２からなる。各舗装板ブロックの大きさは４５ｃｍ×１２８ｃｍ、厚さは５ｃｍで、舗装板ブロック４１は、一端に鉄板を埋め込んだ乗上部４１ａが設けられている点で舗装板ブロック４２と異なる。各舗装板ブロックには４個所の吊上孔４３が形成されている。吊上孔は上部の直径が３ｃｍ、下部の直径が５ｃｍで、下方の径が上方よりも拡がるテーパ状となっている。 Next, a method for lifting an article using the lifting jig A will be described by way of an example in which a paving board block is laid.
As shown in FIG. 11, the pavement plate 4 includes three reinforced concrete pavement plate blocks 41, 42 and 42. Each paving board block has a size of 45 cm × 128 cm and a thickness of 5 cm, and the paving board block 41 is different from the paving board block 42 in that a riding portion 41 a in which an iron plate is embedded at one end is provided. Each pavement block is formed with four lifting holes 43. The lifting hole has a tapered shape in which the upper diameter is 3 cm, the lower diameter is 5 cm, and the lower diameter is wider than the upper diameter.

この舗装板は、図１２に例示するように既存の駐車場の緑化に使用されるものである。この駐車場は、全面がアスファルト舗装となっていたものを、中央の通路４９にアスファルト舗装を残し、両側の駐車スペースに厚さ５ｃｍの植生ブロック４６をアスファルト舗装の上に敷き詰めるが、自動車のタイヤが走行する部分のみ、アスファルト舗装の上に舗装板ブロック４を敷設する。植生ブロック４６には、例えばイワダレソウのような背の低い植物が繁茂する。 This pavement board is used for the greening of an existing parking lot as illustrated in FIG. This parking lot has an asphalt pavement on the entire surface, leaving the asphalt pavement in the central passage 49, and laying vegetation blocks 46 of thickness 5 cm on the asphalt pavement in the parking spaces on both sides. The paving board block 4 is laid on the asphalt pavement only in the portion where the vehicle runs. In the vegetation block 46, for example, a short plant such as Iwadareso grows.

舗装板を敷設するにあたり、まず、揚重機（例えばトラックに装備されている小型揚重機）の吊ワイヤーを吊治具Ａの開口１３、２３に挿通して、吊治具Ａを揚重機で吊り上げ可能にしておく。次にトラックの荷台に積まれている、又は地面に荷下ろしされている舗装板ブロック４１、４２を１枚ずつ吊り上げ、敷設場所に移動して吊り降ろす。吊り上げるときは、図６に示すように、吊治具Ａを吊上孔４３の上に吊り降ろすと、吊ワイヤー３３が緩んで棒状部材１、２の円環部１２、２２の間隔が広がり（又は手で広げ）、棒状部材１、２の下部（折曲部１４、２４）の間隔が狭まり、吊上孔の中に棒状部の下部を挿入することができる。次に、図７に示すように、棒状部材１、２の円環部１２、２２の間隔を狭めた状態で（折曲部１４、２４が吊上孔４３に密着する）吊治具Ａを上昇させると、吊ワイヤー３３にブロックの重さが作用し、棒状部材１、２の円環部１２、２２の間隔が狭まる方向の力（矢印ａ）が作用し、棒状部材の下部の間隔が広がる方向の力（矢印ｂ）が作用するので、吊治具Ａ下部とブロックの吊上孔４３とが強く係合し、安全に吊り上げることができる。 In laying the pavement board, first, the lifting wire of a lifting machine (for example, a small lifting machine installed in a truck) is inserted into the openings 13 and 23 of the lifting jig A, and the lifting jig A is lifted by the lifting machine. Keep it possible. Next, the paving board blocks 41 and 42 loaded on the truck bed or unloaded on the ground are lifted one by one, moved to the laying place and suspended. When lifting, as shown in FIG. 6, when the lifting jig A is hung down on the lifting hole 43, the hanging wire 33 is loosened and the space between the annular portions 12 and 22 of the rod-shaped members 1 and 2 is increased ( Alternatively, the space between the lower portions (folded portions 14, 24) of the rod-shaped members 1, 2 is narrowed, and the lower portion of the rod-shaped portion can be inserted into the lifting hole. Next, as shown in FIG. 7, the hanging jig A is mounted with the space between the annular portions 12 and 22 of the rod-shaped members 1 and 2 narrowed (the bent portions 14 and 24 are in close contact with the lifting hole 43). When raised, the weight of the block acts on the suspension wire 33, a force (arrow a) in the direction in which the distance between the annular portions 12 and 22 of the rod-like members 1 and 2 is reduced, and the gap between the lower portions of the rod-like members is reduced. Since the force in the spreading direction (arrow b) acts, the lower part of the hanging jig A and the lifting hole 43 of the block are strongly engaged and can be lifted safely.

図９は、舗装板ブロック４２を吊り上げた状態である。この場合は、吊治具Ａを取り付けた吊ワイヤー２本を揚重機の吊フック３４に掛けて使用している。吊治具Ａは舗装板ブロック４２の対角の２つの吊上孔に係合させている。舗装板ブロックを吊り上げた状態で敷設する場所に移動し、吊り降ろすと、図６に示すように、吊ワイヤー３３にブロックの重量が作用しなくなるので、円環部１２、２２の間隔が広がり（又は容易に広げることができ）、棒状部材１、２の下部の間隔が狭まるので、吊治具Ａを吊上孔４３から容易に抜き取ることができる。
舗装板ブロック４１も、舗装板ブロック４２と全く同様に吊り上げ、敷設することができる。 FIG. 9 shows a state in which the paving board block 42 is lifted. In this case, two hanging wires attached with the hanging jig A are hung on the hanging hook 34 of the lifting machine. The hanging jig A is engaged with two diagonal lifting holes of the paving board block 42. When the pavement block is moved to the place where it is laid and suspended, the weight of the block does not act on the suspension wire 33 as shown in FIG. Alternatively, the gap between the lower portions of the rod-like members 1 and 2 is narrowed, so that the lifting jig A can be easily removed from the lifting hole 43.
The paving board block 41 can also be lifted and laid just like the paving board block 42.

舗装板ブロック４１、４２を所定位置に吊り降ろした後、図１０に示すように、４個所の吊上孔４３から地中（アスファルト４７、地盤４８）にアンカー４５を、その頭部を吊上孔４３内に露出させた状態で打ち込む。アンカーは鉄筋や鉄杭などである。次に、吊上孔４３内にモルタルなどの充填硬化材４４を充填して硬化させ、舗装板ブロックをアスファルト舗装の上に固定する。 After the pavement block 41, 42 is suspended at a predetermined position, as shown in FIG. 10, the anchor 45 is suspended from the four lifting holes 43 into the ground (asphalt 47, ground 48) and its head is suspended. Driving in the state of being exposed in the hole 43. The anchor is a reinforcing bar or a steel pile. Next, a filling hardening material 44 such as mortar is filled in the lifting holes 43 and hardened, and the paving board block is fixed on the asphalt pavement.

図８は、棒状部材１’、２’の下端部に鈎状部１７、２７を設けた吊治具Ａ’の例である。吊治具Ａ’は、鈎状部を有する以外は前記の吊治具Ａと同じである。鈎状部１７、２７は、開口１３、２３の向いている方向（図２、３の矢印Ｘ方向）で、かつ吊治具Ａの外側方向に突出ように設けられている。この場合、吊り上げる物品（舗装板ブロック）に形成する吊上孔４３’は、下方の径が上方よりも拡がっている段部４３ａが形成されている。さらに段部４３から上方は下方の径が上方よりも拡がるテーパ状となっており、棒状部材１’、２’の下部が吊上孔４３’上部内面に密着している。 FIG. 8 shows an example of a hanging jig A ′ in which hook-shaped portions 17 and 27 are provided at the lower ends of the rod-shaped members 1 ′ and 2 ′. The hanging jig A 'is the same as the hanging jig A except that it has a hook-shaped portion. The hook-shaped portions 17 and 27 are provided so as to protrude in the direction in which the openings 13 and 23 are directed (the direction of the arrow X in FIGS. 2 and 3) and outward of the hanging jig A.
