Description
本発明は、特に巻付け式の耐火被覆材の施工に好適な高所作業車および部材の施工方法に関するものである。 The present invention relates to an aerial work vehicle and a member construction method particularly suitable for construction of a wrapping type fireproof coating material.
従来、巻付け式の耐火被覆材は、一般に昇降式の作業床を備える高所作業車（例えば、特許文献１を参照）を使用して施工されている。図６〜図８は、この高所作業車による従来の施工手順を示したものである。まず、図６のステップＳ１および図７に示すように、厚手の長方形シート状の耐火被覆材１（長さ２ｍ×幅１ｍ程度）を、高所作業車２の作業床３の手摺４に仮置きして鉄骨梁５（Ｈ形鋼）の片側６に配置する。そして、作業床３を上昇させた後、作業床３上の作業者（不図示）が耐火被覆材１の一方の端部を鉄骨梁５の片面上部にピン溶接などにより取付け、吊下げる。高所作業車２を動かさずに取付可能な枚数（図の例では２枚）の耐火被覆材１を隣り合わせに吊下げ施工したら、作業床３を一旦下げて高所作業車２を鉄骨梁５の延在方向に沿って若干移動させ、図８に示すように、作業床３を再び上昇させて次の２枚を鉄骨梁５の片面上部に取付け、吊下げる。以後、この取付け作業を鉄骨梁５の延在方向に繰り返す（図６のステップＳ２）。作業の途中、高所作業車２に積載した耐火被覆材１がなくなったら、その都度、作業床３を下降させて耐火被覆材１を積み込む作業を行う。 2. Description of the Related Art Conventionally, a wrapping-type fireproof covering material is generally constructed using an aerial work vehicle (see, for example, Patent Document 1) provided with an elevating work floor. 6 to 8 show a conventional construction procedure using this aerial work platform. First, as shown in step S1 of FIG. 6 and FIG. 7, a thick rectangular sheet of fireproof covering material 1 (length 2 m × width 1 m) is temporarily applied to the handrail 4 of the work floor 3 of the aerial work vehicle 2. Place it on one side 6 of the steel beam 5 (H-section steel). Then, after raising the work floor 3, an operator (not shown) on the work floor 3 attaches one end of the fireproof covering 1 to the upper part of one surface of the steel beam 5 by pin welding or the like and suspends it. After suspending the fire-resistant covering material 1 of the number that can be attached without moving the aerial work platform 2 (two in the example shown in the figure) next to each other, the work floor 3 is once lowered to attach the aerial work vehicle 2 to the steel beam 5 As shown in FIG. 8, the work floor 3 is raised again, and the next two pieces are attached to the upper part of one side of the steel beam 5 and suspended. Thereafter, this mounting operation is repeated in the extending direction of the steel beam 5 (step S2 in FIG. 6). During the work, when the fireproof covering material 1 loaded on the aerial work vehicle 2 runs out, the work floor 3 is lowered to load the fireproof covering material 1 each time.
こうして鉄骨梁５の片側６への耐火被覆材１の吊下げが完了したら、図６に示すように、鉄骨梁５のもう片側７であって、耐火被覆材１を最初に取付けた位置に対応する箇所に高所作業車２を移動させる（ステップＳ３）。そして、鉄骨梁５の片側６に吊下がった既設の耐火被覆材１の下端を持ち上げて、鉄骨梁５の下面ともう片側７に巻付けてその上部に取付ける。以後、この巻付け作業を、鉄骨梁５の延在方向に沿って高所作業車２を前進させながら行う（ステップＳ４）。ただし、高所作業車２を前進させる場合は、作業床３を必ず下降させて行う。 When the suspension of the fireproof covering material 1 on one side 6 of the steel beam 5 is thus completed, as shown in FIG. 6, it corresponds to the other side 7 of the steel beam 5 and the position where the fireproof covering material 1 is first attached. The aerial work vehicle 2 is moved to the place to be operated (step S3). Then, the lower end of the existing fireproof covering material 1 suspended from one side 6 of the steel beam 5 is lifted, wound around the lower surface of the steel beam 5 and the other side 7 and attached to the upper part thereof. Thereafter, this winding work is performed while the work platform 2 is advanced along the extending direction of the steel beam 5 (step S4). However, when the aerial work vehicle 2 is moved forward, the work floor 3 is always lowered.
しかしながら、上記の従来の施工方法では、次のような問題があった。 However, the conventional construction method described above has the following problems.
高所作業車２は機能的には作業床３を上昇させたまま走行可能であるが、走行中の転倒防止、鉄骨梁５等への挟まれ防止のため、建設業界では作業床３を下降させて走行させることが義務付けられている。そのため、走行前後に作業床３の上下作業が発生し、耐火被覆材取付け作業の効率低下につながっていた。また、そもそも作業床３が小さいため、耐火被覆材１を積載するための高所作業車２の移動回数が増え、耐火被覆材取付け作業の効率低下につながっていた。 The aerial work platform 2 is functionally capable of traveling with the work floor 3 raised, but in the construction industry, the work floor 3 is lowered in order to prevent the vehicle from falling over and being caught in the steel beam 5 or the like. It is obliged to let it run. Therefore, the work up and down of the work floor 3 occurred before and after traveling, which led to a reduction in the efficiency of the fireproof coating material installation work. In addition, since the work floor 3 is small in the first place, the number of times the aerial work vehicle 2 is moved to load the fireproof coating material 1 increases, and the efficiency of the work for attaching the fireproof coating material is reduced.
このため、高所作業車を動かす回数を減らし、耐火被覆材の取付け作業の効率を向上することのできる高所作業車の開発が求められていた。 For this reason, there has been a demand for the development of an aerial work vehicle that can reduce the number of times the aerial work vehicle is moved and improve the efficiency of the work of attaching the fireproof coating material.

以下に、本発明に係る高所作業車および部材の施工方法の実施の形態を図面に基づいて詳細に説明する。なお、以下の説明では、部材が巻付け式の耐火被覆材であり、被取付け部材が鉄骨梁である場合を例にとり説明するが、この実施の形態によりこの発明が限定されるものではない。 Embodiments of an aerial work vehicle and member construction method according to the present invention will be described below in detail with reference to the drawings. In the following description, the case where the member is a wrapping type fireproof covering material and the member to be attached is a steel beam will be described as an example, but the present invention is not limited to this embodiment.
図１および図２に示すように、本発明に係る高所作業車１０は、走行車体１２と、走行車体１２の上に設けられた昇降機構１４と、昇降機構１４の上端に設けられた作業台１６とを備えており、作業台１６に積載した巻付け式の耐火被覆材（部材）をＨ形鋼からなる高所の鉄骨梁５（被取付け部材）に対して取付け施工するために用いられる。なお、本実施の形態で使用する耐火被覆材としては、例えば長さ２ｍ、幅１ｍ、厚さ数１０ｍｍ程度の巻付け式の耐火被覆材を想定しているが、これ以外の寸法であっても構わない。 As shown in FIGS. 1 and 2, an aerial work vehicle 10 according to the present invention includes a traveling vehicle body 12, an elevating mechanism 14 provided on the traveling vehicle body 12, and an operation provided on the upper end of the elevating mechanism 14. And a wrapping-type fireproof covering material (member) loaded on the worktable 16 is used for mounting on a steel beam 5 (attached member) at a high place made of H-shaped steel. It is done. In addition, as a fireproof covering material used in the present embodiment, for example, a wrapping fireproof covering material having a length of about 2 m, a width of 1 m, and a thickness of several tens of millimeters is assumed. It doesn't matter.
作業台１６は、昇降機構１４の伸縮動作によって上下昇降可能となっている。図では昇降機構１４を伸張して作業台１６を上昇させた例を示しているが、昇降機構１４を収縮して作業台１６を床面近くに下降させることも可能である。作業台１６の周囲には、出入口１８を除いて柵体２０が設けられている。この柵体２０の上部は横棒状の手摺２２（積載部）となっており、この手摺２２には耐火被覆材を垂らして積載可能である。 The work table 16 can be moved up and down by the expansion and contraction operation of the lifting mechanism 14. Although the figure shows an example in which the lifting mechanism 14 is extended to raise the work table 16, the lifting mechanism 14 can be contracted to lower the work table 16 near the floor. A fence body 20 is provided around the work table 16 except for the entrance 18. The upper portion of the fence body 20 is a horizontal bar-shaped handrail 22 (loading portion), and a fireproof covering material can be hung on the handrail 22 for loading.
この高所作業車１０は、作業台１６の床寸法を増減調整可能なスライド式（伸縮機構）の寸法調整手段２４と、鉄骨梁５に対する作業台１６の位置を取付け施工に適する位置に合わせるためのレーザー照射手段２６（位置合わせ手段）をさらに備えている。 The aerial work platform 10 is configured to adjust the position of the work table 16 with respect to the steel beam 5 to the position suitable for the installation work by the slide type (extension mechanism) size adjusting means 24 that can increase or decrease the floor size of the work table 16. The laser irradiation means 26 (positioning means) is further provided.
ここで、作業台１６は、第１作業台１６Ａと、柵体２０を備える第２作業台１６Ｂとにより構成され、それぞれ長方形状の作業床を有している。第１作業台１６Ａは、昇降機構１４の上端に固定されている。第２作業台１６Ｂは、第１作業台１６Ａの上方の幅方向Ｘの両側においてスライド可能に固定され、寸法調整手段２４の動作により幅方向Ｘにスライド可能となっている。図１および図２に示すように、第２作業台１６Ｂの幅方向Ｘの内側端部２８が第１作業台１６Ａの外側端部３０と一致するように、第２作業台１６Ｂを幅方向Ｘ外方にスライドして使用することにより作業台１６の幅寸法を拡幅することができる。反対に、第２作業台１６Ｂを幅方向Ｘ内方にスライドして、その内側端部２８どうしを近接配置することにより作業台１６の幅寸法を縮小することができる。 Here, the workbench 16 includes a first workbench 16A and a second workbench 16B including a fence body 20, each having a rectangular work floor. The first work table 16A is fixed to the upper end of the lifting mechanism 14. The second work table 16B is slidably fixed on both sides in the width direction X above the first work table 16A, and is slidable in the width direction X by the operation of the dimension adjusting means 24. As shown in FIGS. 1 and 2, the second workbench 16B is moved in the width direction X so that the inner end 28 in the width direction X of the second workbench 16B coincides with the outer end 30 of the first workbench 16A. The width of the work table 16 can be widened by sliding it outward. On the contrary, the width dimension of the workbench 16 can be reduced by sliding the second workbench 16B inward in the width direction X and arranging the inner end portions 28 close to each other.
本実施の形態では、作業台１６の床面積を拡大することで高所作業車１０の移動回数を減らし、作業歩掛りを向上につなげる。作業台１６の長さＬを例えば２．７ｍと従来よりも大きくすれば、高所作業車１０を移動せず耐火被覆材３枚の取付けが可能となる。また、鉄骨梁５の横幅ｂが４０ｃｍ程度の場合、拡幅後の作業台１６の横幅Ｂを例えば２．０ｍとして従来よりも大きくすれば、高所作業車１０を移動せず鉄骨梁５の両面への耐火被覆材の取付けが可能となる。 In the present embodiment, the number of movements of the aerial work vehicle 10 is reduced by enlarging the floor area of the work table 16, thereby improving the work yield. If the length L of the work table 16 is increased to, for example, 2.7 m, for example, it is possible to attach the three fireproof coating materials without moving the aerial work vehicle 10. Further, when the width b of the steel beam 5 is about 40 cm, if the width B of the work table 16 after widening is set to 2.0 m, for example, to be larger than the conventional one, both the surfaces of the steel beam 5 are not moved without moving the aerial work vehicle 10. It is possible to attach a fireproof coating material to the surface.
なお、拡幅後の作業台１６の横幅Ｂが２．０ｍのままでは高所作業車１０は工事用エレベーター搬器に乗らないため、寸法調整手段２４のスライド動作により、作業時は横幅Ｂを２．０ｍに拡幅し、エレベーターによる上階または下階への盛り替え時は走行車体１２と同じ横幅（例えば１．３ｍ）に縮小できるようにすることが望ましい。 In addition, since the aerial work vehicle 10 does not get on the construction elevator carrier when the width B of the work table 16 after widening remains 2.0 m, the width B is set to 2. It is desirable that the width be increased to 0 m so that it can be reduced to the same lateral width (eg, 1.3 m) as that of the traveling vehicle body 12 when the elevator is changed to the upper floor or the lower floor.
レーザー照射手段２６は、図２に示すように、第１作業台１６Ａの長さ方向Ｙの両側端部であって幅方向Ｘ中央部に設けられ、第１作業台１６から鉛直上方にレーザー可視光３２を照射するものである。このレーザー可視光３２による照射点を目視確認することで、作業者は鉄骨梁５の下フランジと作業台１６の水平方向の相対的な位置関係を把握することができる。そして、例えば２つのレーザー照射手段２６からの照射点の位置が下フランジの中心線上に位置するように、高所作業車１０の位置を調整する。こうすることで、作業台１６を下降させた状態で鉄骨梁５と高所作業車１０の位置整合が可能である。これにより、作業台１６を上昇させても鉄骨梁５に対して作業に最適な位置に１回で容易に位置合わせができるようになるので、高所作業車１０を再度位置合わせする手間が減り、耐火被覆材取付け作業の効率を上げることができる。 As shown in FIG. 2, the laser irradiation means 26 is provided at both end portions in the longitudinal direction Y of the first work table 16 </ b> A and in the center portion in the width direction X, and laser visible from the first work table 16 vertically upward. The light 32 is irradiated. By visually confirming the irradiation point by the laser visible light 32, the operator can grasp the relative positional relationship between the lower flange of the steel beam 5 and the work table 16 in the horizontal direction. Then, for example, the position of the aerial work vehicle 10 is adjusted so that the positions of the irradiation points from the two laser irradiation means 26 are positioned on the center line of the lower flange. By doing so, the steel beam 5 and the aerial work vehicle 10 can be aligned with the work table 16 lowered. As a result, even if the work table 16 is raised, the steel beam 5 can be easily aligned at the optimum position for the work once, so that the labor for repositioning the aerial work vehicle 10 is reduced. In addition, the efficiency of the work for attaching the fireproof coating material can be increased.
このように、本実施の形態の高所作業車１０によれば、作業台１６の床寸法を増大することにより、耐火被覆材の積載容量を増やすことができ、耐火被覆材を作業台１６に積み込むための作業台１６の上下昇降作業数を減らせる。また、作業台１６の床寸法を増大した状態で取付け作業を行うことで、高所作業車１０を動かさずに取付ける耐火被覆材の数量が増えるとともに、作業性が向上する。また、レーザー照射手段２６によって鉄骨梁５に対する作業台１６の位置合わせ効率が向上し、高所作業車１０を必要以上に動かさずに済む。したがって、本実施の形態によれば、高所作業車１０を動かす回数が減り、耐火被覆材の取付け作業の効率を向上することができる。 Thus, according to the aerial work vehicle 10 of the present embodiment, by increasing the floor size of the work table 16, it is possible to increase the load capacity of the fire-resistant coating material, and to add the fire-resistant coating material to the work table 16. The number of up / down operations of the work table 16 for loading can be reduced. Further, by performing the attachment work in a state where the floor size of the work table 16 is increased, the number of fireproof covering materials to be attached without moving the aerial work vehicle 10 is increased and workability is improved. Further, the alignment efficiency of the work table 16 with respect to the steel beam 5 is improved by the laser irradiation means 26, and it is not necessary to move the aerial work vehicle 10 more than necessary. Therefore, according to this Embodiment, the frequency | count of moving the aerial work vehicle 10 reduces, and the efficiency of the installation work of a fireproof coating | covering material can be improved.
次に、本発明に係る部材の施工方法の実施の形態について説明する。 Next, an embodiment of a member construction method according to the present invention will be described.
この施工方法は、上記の高所作業車１０を用いて、作業台１６に積載した耐火被覆材を鉄骨梁５に対して取付け施工する方法である。この施工方法は、作業台１６の床寸法を増減調整する寸法調整ステップＳ１１と、鉄骨梁５に対する作業台１６の位置を取付け施工に適する位置に合わせる位置合わせステップＳ１２と、位置合わせステップＳ１２の後、必要に応じて作業台１６を昇降して停止し、耐火被覆材１を鉄骨梁５に対して取付け施工する施工ステップＳ１３とを備える。 This construction method is a method of attaching and constructing the fireproof covering material loaded on the work table 16 to the steel beam 5 using the above-mentioned work place 10 for aerial work. This construction method includes a dimension adjustment step S11 for increasing / decreasing the floor dimension of the work table 16, a position adjusting step S12 for adjusting the position of the work table 16 with respect to the steel beam 5 to a position suitable for installation work, and a position adjustment step S12. If necessary, the work table 16 is moved up and down to stop, and the fireproof covering material 1 is attached to the steel beam 5 and installed at step S13.
まず、図３に示すように、下降した状態の第２作業台１６Ｂを幅方向Ｘにスライドして作業台１６を拡幅する（ステップＳ１１）。次に、作業台１６の両側の手摺２２に、耐火被覆材１（不図示）を片側３枚ずつ合計６枚を並べて積載する。そして、レーザー照射手段２６および走行車体１２を利用して、鉄骨梁５に対する作業台１６の位置を取付け施工に適する位置に合わせ、例えば作業台１６を作業開始点の鉄骨梁５の真下に配置する（ステップＳ１２）。作業台１６に作業員が搭乗し、作業台１６を上昇させて停止した後、耐火被覆材１の一方の端部を鉄骨梁５の片側６の上部にピン溶接などにより取付け、吊下げる。さらに、この耐火被覆材１の下端を持ち上げて、鉄骨梁５の下フランジ面ともう片側７に巻付けてその上部に取付ける（ステップＳ１３）。なお、この作業は、鉄骨梁５の片側６の上部に対して３枚の耐火被覆材１を並べて取付けた後に、それぞれを下フランジ面ともう片側７に巻付けて取付けてもよいし、１枚づつ行ってもよい。 First, as shown in FIG. 3, the second work table 16B in the lowered state is slid in the width direction X to widen the work table 16 (step S11). Next, a total of six fireproof covering materials 1 (not shown) are arranged and stacked on the handrails 22 on both sides of the work table 16, three on each side. Then, by using the laser irradiation means 26 and the traveling vehicle body 12, the position of the work table 16 with respect to the steel beam 5 is adjusted to a position suitable for attachment work, and for example, the work table 16 is arranged directly below the steel beam 5 at the work start point. (Step S12). After an operator gets on the work table 16 and raises and stops the work table 16, one end of the fireproof covering material 1 is attached to the upper part of one side 6 of the steel beam 5 by pin welding or the like and suspended. Further, the lower end of the fireproof covering material 1 is lifted, wound around the lower flange surface of the steel beam 5 and the other side 7 and attached to the upper part (step S13). In this operation, after attaching the three fireproof covering materials 1 side by side to the upper portion of one side 6 of the steel beam 5, each may be wound around the lower flange surface and the other side 7 and attached. You may go one by one.
こうして、高所作業車１０を動かさずに３枚の耐火被覆材１を隣り合わせに吊下げ施工したら、作業台１６を一旦下げて高所作業車１０を鉄骨梁５の延在方向に沿って若干移動させ、耐火被覆材１を手摺２２に積み込んで、作業台１６を再び上昇させて次の３枚を鉄骨梁５の両側面および下面に巻付けて取付ける。以後、この取付け作業を鉄骨梁５の延在方向に繰り返す（図４のステップＳ１４）。 In this way, when the three fireproof covering materials 1 are hung side by side without moving the aerial work vehicle 10, the work table 16 is once lowered to slightly move the aerial work vehicle 10 along the extending direction of the steel beam 5. Then, the fireproof covering material 1 is loaded on the handrail 22, the work table 16 is raised again, and the next three pieces are wound around and attached to both side surfaces and the lower surface of the steel beam 5. Thereafter, this mounting operation is repeated in the extending direction of the steel beam 5 (step S14 in FIG. 4).
このように、本実施の形態によれば、高所作業車１０を動かす回数が減り、耐火被覆材１の取付け作業の効率を向上することができる。 Thus, according to this Embodiment, the frequency | count of moving the aerial work vehicle 10 reduces, and the efficiency of the attachment operation | work of the fireproof coating material 1 can be improved.
また、作業台１６の長さＬが長いため、高所作業車１０を動かさず取付ける耐火被覆材１の枚数が増える。また、作業台１６の横幅Ｂが大きいため、高所作業車１０を動かさず耐火被覆材１の吊下げと巻込みが同時に行える。さらに、耐火被覆材１の搭載枚数が増えるため、積み込みのための作業台１６の上下昇降作業および積み込み作業の回数を減らすことができる。 Further, since the length L of the work table 16 is long, the number of the fireproof covering materials 1 to be mounted without moving the work platform 10 at an elevated position increases. Moreover, since the horizontal width B of the work table 16 is large, the fireproof covering material 1 can be suspended and wound at the same time without moving the aerial work vehicle 10. Furthermore, since the number of fireproof covering materials 1 to be mounted is increased, the number of up / down operations and loading operations of the work table 16 for loading can be reduced.
上記の実施の形態において、作業台１６に対する耐火被覆材の積載可能数量を増大するために、手摺２２を水平方向に多重に設けてもよい。この場合、例えば、図５に示すように、手摺２２を幅方向Ｘに２重に設け、耐火被覆材１の積載可能枚数を増やしてもよい。このようにすることで、耐火被覆材１の積み込み作業による取付け作業の中断を減らし、耐火被覆材取付け作業の効率を上げることができる。 In the above-described embodiment, in order to increase the loadable quantity of the fireproof coating material on the workbench 16, the handrails 22 may be provided in multiple numbers in the horizontal direction. In this case, for example, as shown in FIG. 5, the handrails 22 may be provided in the width direction X to increase the number of stackable fireproof covering materials 1. By doing in this way, the interruption of the attachment operation by the loading operation | work of the fireproof coating material 1 can be reduced, and the efficiency of a fireproof coating material attachment operation can be raised.
また、上記の実施の形態においては、巻付け式の耐火被覆材を鉄骨梁に取付け施工する場合を例にとり説明したが、本発明はこれに限るものではなく、耐火被覆材以外の部材を被取付け部材に取付ける構成であってもよい。このようにしても、上記と同様の作用効果を奏することが可能である。 In the above embodiment, the case where the winding type fireproof coating material is attached to the steel beam has been described as an example. However, the present invention is not limited to this, and a member other than the fireproof coating material is covered. The structure attached to an attachment member may be sufficient. Even if it does in this way, it is possible to show the effect similar to the above.
