Abstract
Description
本発明は、ＡＬＣ等のコンクリート製のパネルの積み下ろし作業を行う際に用いるパネル浮かし治具及びパネルの移動方法に関するものである。 The present invention relates to a panel floating jig used when loading and unloading a concrete panel such as ALC and a panel moving method.
従来より、建物の外壁として使用されるＡＬＣ（軽量気泡コンクリート）等のコンクリート製のパネルには、意匠性を向上させるための化粧目地（溝）が形成されことが多い。 Conventionally, decorative joints (grooves) for improving design are often formed on concrete panels such as ALC (lightweight cellular concrete) used as the outer wall of a building.
一方、ＡＬＣ等のコンクリート製のパネルの積み下ろし作業を行う際には、枕木の上にパネルを積み重ねられたパネルに、枕木によって形成された空間を利用してナイロン等の化学繊維からなるスリング（両端部がリング状に加工された帯状の吊り上げ用治具）を巻きつけ、揚重機等で吊り上げる、あるいはパレットの上にパネルを積み重ねてパレットごと吊り上げるという方法が主流であった。 On the other hand, when a concrete panel such as ALC is loaded and unloaded, a sling made of chemical fibers such as nylon (both ends) is formed on the panel stacked on the sleeper using the space formed by the sleeper. The mainstream method is to wrap a belt-shaped lifting jig whose portion is processed into a ring shape and lift it with a lifting machine or the like, or stack panels on a pallet and lift the whole pallet.
このような方法の場合、パネルの吊り上げ枚数は枕木あるはパレットの上に積み重ねられたパネルの数に限定されてしまい、任意の枚数を吊り上げることが困難であった。 In such a method, the number of panels to be lifted is limited to the number of sleepers or panels stacked on a pallet, and it is difficult to lift an arbitrary number of panels.
特許文献１には、ＰＣ床版の中空孔に充填されたモルタルによって固着された係止具を利用してＰＣ床版を揚重する技術が開示されている。この技術によれば、積み重ねられた複数枚のパネルうち任意の枚数のパネルを吊り上げることが可能である。 Patent Document 1 discloses a technique for lifting a PC floor slab using a locking tool fixed by a mortar filled in a hollow hole of the PC floor slab. According to this technique, it is possible to lift an arbitrary number of panels among a plurality of stacked panels.
しかし、ＡＬＣパネルはＰＣパネルと比較して脆弱であり、上記特許文献１に記載されたような加工を施して複数のパネルを吊り上げた場合、その重量によって中空孔付近が破損する虞がある。また、中空孔の加工、モルタルの充填、モルタルの養生、モルタルで固着された係止具の取り外し等が必要となり手間や時間を要するという問題もあった。 However, the ALC panel is more fragile than the PC panel, and when a plurality of panels are lifted by processing as described in Patent Document 1, the vicinity of the hollow hole may be damaged by the weight. In addition, processing of the hollow hole, filling of the mortar, curing of the mortar, removal of the locking tool fixed with the mortar, etc. are required, and there is a problem that it takes time and effort.
本発明は、このような従来技術の有する課題を解決し、主としてＡＬＣからなり化粧目地等の溝が形成されたパネルの移動作業において、簡易かつ安全な方法で任意の枚数のパネルにスリングを巻き付けて吊り上げ、移動させることができるパネル浮かし治具及びパネルの移動方法を提供することを目的とするものである。 The present invention solves such problems of the prior art, and wraps a sling around an arbitrary number of panels in a simple and safe manner during the movement of a panel mainly made of ALC and formed with grooves such as decorative joints. It is an object of the present invention to provide a panel floating jig that can be lifted and moved and a method for moving the panel.
上記課題を解決する為に、本発明に係るパネル浮かし治具の構成は、一方の端面から対向する他方の端面にかけて直線状の複数の溝が形成された面を下向きにして積み重ねられたパネルに対し吊り上げ用のスリングを巻きつけるために、該パネルを浮かすパネル浮かし治具であって、フック等を引っ掛けるための環状の引っ掛け片を中心部に備えた水平アームと、下端に略水平方向の挿通孔を備え、水平アームから垂下する一対の垂下アームと、
パネルの溝形状に対応した形状を有し、垂下アームの挿通孔に挿通されるとともにパネルの端面から溝に挿し込まれるパネル支持棒と、からなることを特徴としている。
In order to solve the above problems, the configuration of the panel floating jig according to the present invention is a panel stacked with a plurality of straight grooves formed downward from one end face to the other facing end face. A panel floating jig for floating the sling for lifting the panel, a horizontal arm having an annular hook piece for hooking a hook or the like at the center, and a substantially horizontal insertion at the lower end A pair of hanging arms with holes and hanging from a horizontal arm;
It has a shape corresponding to the groove shape of the panel, and is characterized by comprising a panel support rod that is inserted into the insertion hole of the hanging arm and is inserted into the groove from the end face of the panel.
上記構成において、一対の垂下アームの間隔がパネルの幅寸法に対応して調整自在に装着されるのが好ましい。 In the above configuration, it is preferable that the interval between the pair of hanging arms is mounted so as to be adjustable in accordance with the width dimension of the panel.
また、本発明に係るパネルの移動方法は、下記工程を有することを特徴としている。
（１）一方の側端面から対向する他方の側端面にかけて直線状の複数の溝が形成された複数のパネルを、溝が形成された面が下向きになるように所定場所に積み重ねる工程。
（２）前記複数のパネルのうち上から所定枚数目のパネルの溝にパネル支持棒を挿し込み、該パネル支持棒を上昇させて、所定枚数のパネルからなるパネル群の長さ方向の一端側を浮かす工程。
（３）前記パネル群を浮かした状態で、前記パネル群下方の隙間を利用して前期パネル群にスリングを巻きつける工程。
（４）前記パネル支持棒を降下させ浮かした前記パネル群を前記スリングが巻きついた状態で当初の位置に戻す工程。
（５）前記パネル支持棒を抜き取る工程。
（６）前記スリングを揚重機のフックに引っ掛けて前記パネル群を吊り上げ、所定位置まで水平移動させたのち、前記パネル群を着地させる工程。
Moreover, the moving method of the panel which concerns on this invention has the following processes.
(1) A step of stacking a plurality of panels in which a plurality of linear grooves are formed from one side end surface to the opposite side end surface in a predetermined place so that the surface on which the grooves are formed faces downward.
(2) A panel support bar is inserted into a groove of a predetermined number of panels from the top of the plurality of panels, and the panel support bar is lifted to end one end side in the length direction of a panel group consisting of the predetermined number of panels The process of floating.
(3) A step of winding a sling around the panel group using the gap below the panel group with the panel group floating.
(4) A step of returning the panel group, which is floated by lowering the panel support bar, to the initial position in a state where the sling is wound.
(5) A step of extracting the panel support bar.
(6) A step of hanging the sling on a hook of a hoist to lift the panel group, horizontally moving it to a predetermined position, and then landing the panel group.
本発明に係るパネル浮かし治具及びパネルの移動方法によれば、パネルの表面の溝にパネル支持棒を挿し込み、パネル支持棒を上昇させることによってパネル群を浮かせるので、ＡＬＣ等の比較的脆弱な材質からなるパネルであっても、パネルの強度上の問題を有することなく、任意の枚数のパネル群を一時的に安全に浮かしてその下方に隙間をつくって、スリングを巻きつけ、該スリングを揚重機等で引き上げることによってパネル群を移動させることができる。特に、表面に化粧目地が形成された壁パネルの場合、化粧目地がそのまま利用できるので、余計な手間やコストが発生しない。 According to the panel floating jig and the panel moving method according to the present invention, the panel group is floated by inserting the panel support bar into the groove on the surface of the panel and raising the panel support bar. Even if the panel is made of a different material, any number of panel groups can be temporarily lifted safely to create a gap below the sling without having any problems with the strength of the panel. The panel group can be moved by pulling up with a lifting machine or the like. In particular, in the case of a wall panel having a makeup joint formed on the surface, the makeup joint can be used as it is, so that unnecessary labor and cost do not occur.
また、着脱が容易であり、積み下ろし作業に要する時間の短縮を図ることができる。 In addition, it is easy to attach and detach, and the time required for the loading and unloading work can be shortened.
以下に、図を参照しながら本発明の一実施形態について説明する。本実施例において対象となるパネル１は、３０５ｍｍの平面モジュールを有する鉄骨造工業化住宅の外壁として使用されるＡＬＣからなるものである。 An embodiment of the present invention will be described below with reference to the drawings. The target panel 1 in this embodiment is made of ALC used as an outer wall of a steel-frame industrial housing having a flat module of 305 mm.
図１に示すパネル１は、厚みが７５ｍｍであり、主として使用されるパネル１の幅寸法は６１０ｍｍと３０５ｍｍである。（図１では代表して６１０ｍｍのパネルを示している。）パネル１の表側の面には、一方の側端面から対向する他方の側端面に到達する直線状の複数の横化粧目地（溝）２、及び、上端面から下端面に達する縦化粧目地３が、所定のピッチでパネル表面を切削加工することにより形成されている。 The panel 1 shown in FIG. 1 has a thickness of 75 mm, and the width dimensions of the panel 1 mainly used are 610 mm and 305 mm. (In FIG. 1, a 610 mm panel is shown as a representative.) On the front side surface of the panel 1, a plurality of linear decorative joints (grooves) that reach from one side end surface to the other side end surface facing each other. 2 and a vertical decorative joint 3 reaching from the upper end surface to the lower end surface is formed by cutting the panel surface at a predetermined pitch.
図２に示すパネル浮かし治具Ｂは、水平アーム１０、水平アーム１０から垂下する一対の垂下アーム２０、水平アーム１０に垂下アーム２０を固定する固定具３０、及び水平アーム１０下端に装着されるパネル支持棒４０からなる。 The panel floating jig B shown in FIG. 2 is attached to the horizontal arm 10, a pair of hanging arms 20 that hang from the horizontal arm 10, a fixture 30 that fixes the hanging arm 20 to the horizontal arm 10, and a lower end of the horizontal arm 10. It consists of a panel support bar 40.
水平アーム１０は、本体１１がパイプ状の鋼材からなり、本体１０中心部の上面には揚重機のフック等を引っ掛けるための環状の引っ掛け片１２が溶接されている。また、水平アーム１０には、垂下アームを２０パネルの幅に対応させて固定する際の目安となる目盛１３が刻まれている。 In the horizontal arm 10, the main body 11 is made of a pipe-shaped steel material, and an annular hook piece 12 for hooking a hook or the like of a lifting machine is welded to the upper surface of the central portion of the main body 10. Further, the horizontal arm 10 is engraved with a scale 13 that serves as a guide for fixing the hanging arm in correspondence with the width of the 20 panel.
垂下アーム２０は、水平アーム１０から左右対称に垂下する一対の部材であり、本体２１は鋼材からなるフラットバーで構成され、その上端には水平アームを挿通するための水平アーム挿通孔２２が穿設され、下端にはパネル支持棒を挿通するための筒状のパネル支持棒挿通部２３を備えている。 The drooping arm 20 is a pair of members that hang symmetrically from the horizontal arm 10, the main body 21 is formed of a flat bar made of steel, and a horizontal arm insertion hole 22 for inserting the horizontal arm is formed at the upper end thereof. A cylindrical panel support bar insertion portion 23 for inserting the panel support bar is provided at the lower end.
垂下アーム２０は、水平アーム１０に対して２つのリング状の固定具３０で挟持され固定される。固定具３０にはネジ孔が穿設されており、該ネジ孔に蝶ネジ３１を捻じ込みその先端を水平アーム１０に押し付けることで固定具３０が所定位置に固定される。垂下アーム２０の長さはパネル１の厚みや同時に浮かせる（＝スリングで吊り上げる）パネル１の枚数（本実施例では５枚）に応じて適宜設定される。 The drooping arm 20 is clamped and fixed to the horizontal arm 10 by two ring-shaped fixtures 30. The fixing tool 30 has a screw hole, and the fixing tool 30 is fixed at a predetermined position by screwing a thumbscrew 31 into the screw hole and pressing the tip of the thumb screw 31 against the horizontal arm 10. The length of the hanging arm 20 is appropriately set according to the thickness of the panel 1 and the number of panels 1 that are simultaneously floated (= lifted by a sling) (5 in this embodiment).
パネル支持棒４０は、パネル１が平坦な面に載置された状態でパネル１の端面から横化粧目地２に差し込むことができる径を有する円形断面の鋼材からなる。なお、単純な形状であれば横化粧目地２の形状に合致する断面形状としてもよい。（この場合、横化粧目地２に接する面積が増えパネル１の損傷の可能性を軽減することができる。） The panel support bar 40 is made of a steel material having a circular cross section having a diameter that can be inserted into the horizontal decorative joint 2 from the end face of the panel 1 in a state where the panel 1 is placed on a flat surface. In addition, if it is a simple shape, it is good also as a cross-sectional shape which corresponds to the shape of the horizontal decorative joint 2. (In this case, the area in contact with the horizontal decorative joint 2 increases, and the possibility of damage to the panel 1 can be reduced.)
本実施例では、２本の垂下アーム２０のパネル支持棒挿通部２３の夫々に比較的短いパネル支持棒４０を挿通する構成であるが、1本のパネル支持棒４０を２本の垂下アーム２０のパネル支持棒挿通部２３に挿通する構成としてもよい。前者は作業性や携帯性に優れる。一方、後者はパネル１をより安定して保持することができ、縦化粧目地２に接する面積が増え損傷もより少なくすることができる。 In this embodiment, a relatively short panel support bar 40 is inserted into each of the panel support bar insertion portions 23 of the two hanging arms 20, but one panel support bar 40 is inserted into the two hanging arms 20. It is good also as a structure inserted in the panel support rod insertion part 23 of this. The former is excellent in workability and portability. On the other hand, the latter can hold the panel 1 more stably, and the area in contact with the vertical decorative joint 2 can be increased and the damage can be reduced.
パネル支持棒４０を２本で構成する場合、パネル支持棒挿通部２３とパネル支持棒４０との間の「遊び」やパネル支持棒挿通部２３の長さに応じて、パネル支持棒４０の先端が垂れ下がるので、この垂れ下がりを考慮してパネル支持棒挿通部２３の軸の方向を設定する（若干上向きの設計とする）のが好ましい。 When the panel support bar 40 is composed of two pieces, the tip of the panel support bar 40 depends on “play” between the panel support bar insertion part 23 and the panel support bar 40 or the length of the panel support bar insertion part 23. Therefore, it is preferable to set the direction of the axis of the panel support bar insertion portion 23 in consideration of the sag (with a slightly upward design).
次に、図３〜図６を参照して、パネル浮かし治具Ｂを用いたパネル１の移動方法について説明する。本実施例は、トラックの荷台５０に積み込まれた複数のパネル１を建築現場に搬送して、所定枚数のパネル１からなるパネル群Ａをトラックの荷台５０から建築現場の所定位置に揚重機を用いて降ろす場合を想定したものであり、以下の手順で行われる。 Next, a method of moving the panel 1 using the panel floating jig B will be described with reference to FIGS. In the present embodiment, a plurality of panels 1 loaded on a truck bed 50 are transported to a building site, and a panel group A consisting of a predetermined number of panels 1 is moved from the truck bed 50 to a predetermined position on the building site. It is assumed to be used and lowered, and is performed according to the following procedure.
（１）トラックの荷台５０に枕木５１を並べ、枕木の上にパネル１の表側（化粧目地の面）を下向きにして積み重ねる。 (1) The sleepers 51 are arranged on the truck bed 50 and stacked on the sleepers with the front side of the panel 1 (the face of the joint) facing downward.
（２）揚重機のフック５２を水平アーム１０の引っ掛け片１２に引っ掛けてパネル支持棒４０が未装着の状態のパネル浮かし治具Ｂを吊り上げ、パネル１の所定位置（長さ方向の一方の端部寄りの横化粧目地２の位置）付近まで水平移動させ、更にパネル浮かし治具Ｂを2本の垂下アーム２０でパネル１を挟み込むような状態で降下させる。 (2) The hook 52 of the lifting machine is hooked on the hooking piece 12 of the horizontal arm 10 to lift the panel floating jig B with the panel support bar 40 not attached, and a predetermined position (one end in the length direction) of the panel 1 is lifted. Next, the panel is moved horizontally to the vicinity of the side makeup joint 2 near the part), and the panel lifting jig B is lowered with the two hanging arms 20 sandwiching the panel 1.
（３）垂下アーム２０のパネル支持棒挿通部２３の位置を、上から所定枚数目（例えば５枚のパネルを吊り上げるのであれば上から５枚目）のパネル１の横化粧目地２の位置に合わせ、パネル支持棒４０をパネル支持棒挿通部２３に挿通するとともに、横化粧目地２に挿し込む（以上図３を参照）。 (3) The position of the panel support rod insertion portion 23 of the hanging arm 20 is set to the position of the horizontal decorative joint 2 of the panel 1 of a predetermined number from the top (for example, the fifth from the top if five panels are lifted). In addition, the panel support bar 40 is inserted into the panel support bar insertion portion 23 and also inserted into the side decorative joint 2 (see FIG. 3 above).
（４）パネル浮かし治具Ｂ（パネル支持棒４０）を揚重機で上昇させて、所定枚数のパネル１（パネル群Ａ）の長さ方向の一端をスリング５３が巻きつけられる程度に浮かす。 (4) The panel floating jig B (panel support bar 40) is lifted by a lifting machine, and one end in the length direction of a predetermined number of panels 1 (panel group A) is floated to the extent that the sling 53 is wound.
（５）パネル群Ａを浮かした状態で、パネル群Ａ下方の隙間を利用してパネル群Ａにスリング５３を巻きつけて、スリング５３の一方の端部を他方の端部の環の中に挿通しておく。なお、スリング５３はパネル群Ａを吊り上げた際に略水平となるように、パネル群Ａの両端部からほぼ等しい位置２箇所に巻きつける（以上図４を参照）。 (5) With the panel group A floating, the sling 53 is wound around the panel group A using the gap below the panel group A, and one end of the sling 53 is placed in the ring at the other end. Insert it. The sling 53 is wound around two substantially equal positions from both ends of the panel group A so as to be substantially horizontal when the panel group A is lifted (see FIG. 4 above).
（６）スリング５３が巻きついた状態でパネル浮かし治具Ｂ（パネル支持棒４０）を降下させ、パネル群Ａを再度荷台５０に残るパネル１の上に積み重ねる（以上図５を参照）。 (6) The panel floating jig B (panel support bar 40) is lowered while the sling 53 is wound, and the panel group A is stacked again on the panel 1 remaining on the loading platform 50 (see FIG. 5 above).
（７）パネル支持棒４０を抜き取り、パネル浮かし治具Ｂを上昇させて外す。 (7) Pull out the panel support bar 40 and lift the panel lifting jig B to remove it.
（８）スリング５３を揚重機のフック５２に引っ掛け、フック５２を上昇させてパネル群Ａを吊り上げ、予め枕木が並べられた建築現場の所定位置まで水平移動させる（以上図６を参照）。 (8) The sling 53 is hooked on the hook 52 of the hoist, the hook 52 is raised, the panel group A is lifted, and horizontally moved to a predetermined position on the construction site where sleepers are arranged in advance (see FIG. 6 above).
（９）パネル群Ａを枕木を介して所定位置に着地させる (9) Land the panel group A at a predetermined position through the sleepers.
（１０）スリング５３をフック５２から外し抜き取る。 (10) Remove the sling 53 from the hook 52 and remove it.
上記構成によれば、パネル１の意匠性を向上させるために形成された表面の横化粧目地（溝）２を利用してパネル支持棒４０を挿し込み、パネル支持棒４０を上昇させるパネル群Ａを浮かせることによって、比較的脆弱なＡＬＣからなるパネル１を強度上の問題を有することなく、また、余計な手間やコストを発生させることなく、任意の枚数のパネル群Ａを一時的に浮かせてその下方に隙間をつくってスリング５３を巻きつけ、スリング５３を揚重機で引き上げることによってパネル群Ａを移動させることができる。また、着脱が容易であり、積み下ろし作業に要する時間の短縮を図ることができる。 According to the said structure, the panel group A which inserts the panel support bar 40 using the horizontal decorative joint (groove) 2 of the surface formed in order to improve the designability of the panel 1, and raises the panel support bar 40 The panel 1 made of relatively fragile ALC can be floated temporarily without causing any problems in strength, without generating extra time and cost. The panel group A can be moved by winding the sling 53 with a gap below it and lifting the sling 53 with a lifting machine. In addition, it is easy to attach and detach, and the time required for the loading and unloading work can be shortened.
上記実施例では、スリング５３を用いているが、上記浮かし治具Ｂを２セット用いて、或いは、パネル群Ｂを所定の間隔を有して２点で支持し得るような治具を用いて、パネル群Ａにスリング５３を巻きつける過程を経ることなく、パネル群Ｂを直接吊り上げ移動させることも可能である。 In the above embodiment, the sling 53 is used. However, two sets of the floating jig B are used, or a jig that can support the panel group B at two points with a predetermined interval is used. The panel group B can be directly lifted and moved without going through the process of winding the sling 53 around the panel group A.
また、通常溝が形成されない床用パネルであっても、下面に溝を形成しておくことで、同様の手順で吊り上げ移動させることができる。 Moreover, even if it is a floor panel in which a groove | channel is not normally formed, it can be lifted and moved in the same procedure by forming a groove | channel in the lower surface.
本発明はＡＬＣパネルに好適であるが、PCパネル等の他のパネル状建築材料にも適用が可能である。 The present invention is suitable for ALC panels, but can also be applied to other panel-shaped building materials such as PC panels.
