Description

本発明は、外壁材取付システムに関する。詳しくは、建築中の建物に外壁材を取り付ける外壁材取付システムに関する。   The present invention relates to an outer wall material mounting system. Specifically, the present invention relates to an outer wall material attachment system for attaching an outer wall material to a building under construction.

従来より、カーテンウォールやプレキャストコンクリート版などの外壁材は、以下の手順で取り付けられる。すなわち、現場敷地内の地上面の一部を区画して建方ヤードとし、搬入車両からこの建方ヤードに外壁材を荷下ろして集積しておく。そして、揚重クレーンにて、この建方ヤードから外壁材を揚重して所定位置に取り付けてゆく(特許文献1参照)。   Conventionally, outer wall materials such as curtain walls and precast concrete plates are attached by the following procedure. That is, a part of the ground surface in the site site is divided into a construction yard, and the outer wall material is unloaded from the carrying vehicle to the construction yard and accumulated. Then, the outer wall material is lifted from the building yard by a lifting crane and attached to a predetermined position (see Patent Document 1).

特開平7−76932号公報Japanese Patent Laid-Open No. 7-76932

しかしながら、現場敷地内の一部に建方ヤードを設けると、この建方ヤード部分の工事に着手するのが遅延するうえに、建方ヤードを迂回して搬出入の導線を設ける必要があるため、工程管理が難しくなる、という問題があった。   However, if a construction yard is provided in a part of the site site, it will be delayed to start the construction of the construction yard part, and it will be necessary to bypass the construction yard and provide lead-in / out leads. There was a problem that process management became difficult.

そこで、近年、建物の所定のフロアを建方ヤードとして利用することが提案されている。すなわち、外壁材を搬入して、建方ヤードに集積しておき、この集積した外壁材を床端部まで運搬し、揚重クレーンで吊り上げて、建物に取り付ける。   Therefore, in recent years, it has been proposed to use a predetermined floor of a building as a building yard. That is, the outer wall material is carried in and accumulated in the building yard, and the accumulated outer wall material is transported to the end of the floor, lifted by a lifting crane, and attached to the building.

ここで、建方ヤードとなるフロアの階高に対して外壁材の長さが長い場合、外壁材を吊り上げる手順は、以下のようになる。
まず、台車を2台用意し、一方の台車に外壁材の上側を載置するとともに、他方の台車に外壁材の下側を載置して、外壁材を略水平に寝かせた状態とする。ここで、外壁材の上側を支持する台車を上側支持台車とし、外壁材の下側を支持する台車を下側支持台車とする。具体的には、下側支持台車は、外壁材の下側でかつ中心寄りの位置を支持しており、外壁材の下に隠れている。
Here, when the length of the outer wall material is long with respect to the height of the floor serving as the building yard, the procedure for lifting the outer wall material is as follows.
First, two trolleys are prepared, and the upper side of the outer wall material is placed on one of the trolleys, and the lower side of the outer wall material is placed on the other trolley so that the outer wall material is laid substantially horizontally. Here, a cart that supports the upper side of the outer wall material is an upper support cart, and a cart that supports the lower side of the outer wall material is a lower support cart. Specifically, the lower support carriage supports a position below the outer wall material and closer to the center, and is hidden under the outer wall material.

次に、作業員が外壁材を押して床端部まで運搬し、外壁材の上側を床端部側に配置する。
次に、揚重クレーンの吊りフックを建物の外壁面沿いに下ろして、この揚重クレーンで外壁材の上側を支持した後、上側支持台車を取り外す。
Next, the worker pushes the outer wall material and carries it to the floor end, and arranges the upper side of the outer wall material on the floor end side.
Next, the lifting hook of the lifting crane is lowered along the outer wall surface of the building, the upper side of the outer wall material is supported by the lifting crane, and then the upper support carriage is removed.

次に、下側支持台車の後方の床面に端太角材を敷き、外壁材の下端縁がこの端太角材の上に載るように、揚重クレーンを巻上げて外壁材の上側を上方に吊り上げ、外壁材を建て起こす。
その後、さらに揚重クレーンを巻き上げて、外壁材を上方に吊り上げながら外部に向かって引き出す。このとき、外壁材が自重により上側を中心として回転し、この回転力により外壁材の下側が外部に向かって引っ張られる。そこで、外壁材の下端側に介助ロープを連結しておき、作業員がこの介助ロープを内側に引っ張って、外壁材の下端側の移動を調整する。
Next, lay an end thick square on the floor behind the lower support carriage, wind up the lifting crane so that the lower edge of the outer wall rests on the end thick square, and lift the upper side of the outer wall upward Build up the outer wall material.
Thereafter, the lifting crane is further wound up and pulled out while lifting the outer wall material upward. At this time, the outer wall material rotates around the upper side by its own weight, and the lower side of the outer wall material is pulled outward by this rotational force. Therefore, an assistance rope is connected to the lower end side of the outer wall material, and an operator pulls the assistance rope inward to adjust the movement of the outer wall material on the lower end side.

以上の手法では、外壁材を移動する際、下側支持台車が外壁材の下に隠れているため、作業員は、下側支持台車ではなく外壁材を押して移動する。また、外壁材を建て起こす際、作業員が介助ロープの力加減を微調整する必要があった。そのため、外壁材を精度良く制御するのが難しく、外壁材取付け作業の作業効率が低下していた。   In the above method, when the outer wall material is moved, the lower support cart is hidden under the outer wall material, so that the worker moves by pushing the outer wall material instead of the lower support cart. Also, when building up the outer wall material, it was necessary for the workers to fine-tune the force of the assistance rope. Therefore, it is difficult to control the outer wall material with high accuracy, and the work efficiency of the outer wall material mounting work has been reduced.

本発明は、建方ヤードとなるフロアの階高に対して外壁材の長さが長い場合でも、外壁材取付け作業の作業効率を向上できる外壁材取付システムを提供することを目的とする。   An object of this invention is to provide the outer wall material attachment system which can improve the work efficiency of an outer wall material attachment operation | work, even when the length of an outer wall material is long with respect to the height of the floor used as a building yard.

請求項1に記載の外壁材取付システムは、建築中の建物に外壁材を取り付ける外壁材取付システムであって、前記建物の所定フロアには、床が構築され、前記外壁材の下側を支持して当該外壁材を前記所定フロア内で運搬可能な台車を備え、当該台車は、前記外壁材の下端縁が載置されて前記床の上を走行可能な台車本体と、当該台車本体から後方かつ上方に延びる把持部と、を備えることを特徴とする。   The outer wall material mounting system according to claim 1 is an outer wall material mounting system for mounting an outer wall material to a building under construction, and a floor is constructed on a predetermined floor of the building and supports a lower side of the outer wall material. A carriage capable of transporting the outer wall material within the predetermined floor, and the carriage has a carriage main body on which a lower end edge of the outer wall material is placed and can travel on the floor, and a rear side from the carriage main body. And a grip portion extending upward.

外壁材としては、アルミカーテンウォールやプレキャストコンクリート版が挙げられる。   Examples of the outer wall material include an aluminum curtain wall and a precast concrete plate.

この発明によれば、外壁材の下端縁を台車の上に載せて、この台車で外壁材の下端縁を支持し、さらに台車本体から後方かつ上方に延びる把持部を設けた。
よって、台車を前進や停止させる際、作業員が把持部を把持することで、従来のようにかがんだ姿勢で操作する必要がなく、立った姿勢で台車を操作できるので、作業員の負担を軽減して、外壁材の移動を精度良く制御できる。
また、把持部が後方に延びているため、作業員が床の端部から離れることができ、作業の安全性が向上する。
According to this invention, the lower end edge of the outer wall material is placed on the carriage, the lower end edge of the outer wall material is supported by the carriage, and the grip portion extending rearward and upward from the carriage body is provided.
Therefore, when the carriage is moved forward or stopped, it is not necessary for the worker to operate in a leaning posture by gripping the gripping part, and the cart can be operated in a standing posture. The movement of the outer wall material can be controlled with high accuracy.
Moreover, since the holding | gripping part is extended back, an operator can leave | separate from the edge part of a floor, and the safety | security of work improves.

また、外壁材を建て起こす際、外壁材の下端縁を台車の上に載せた状態で建て起こす。よって、従来のように外壁材の下端縁を端太角材の上に載せて建て起こす場合に比べて、作業員の踏ん張りが効くから、台車を確実に操作できる。
また、外壁材を建て起こす際に外壁材の自重により台車が床の外側に向かって引っ張られても、作業員は、把持部により台車を直接的に操作できるので、従来のように介助ロープを引っ張って台車を間接的に操作する場合に比べて、外壁材を安全かつ精度良く制御できる。
Moreover, when building up the outer wall material, the lower wall edge of the outer wall material is built up in a state of being placed on the carriage. Therefore, compared with the conventional case where the lower end edge of the outer wall material is placed on the end thick square member and built up, the operator's struts are effective, so that the cart can be operated reliably.
Also, even when the trolley is pulled toward the outside of the floor due to the weight of the outer wall material when the outer wall material is erected, the operator can operate the trolley directly with the gripping part, so that the support rope can be Compared to the case where the carriage is indirectly operated by pulling, the outer wall material can be controlled safely and accurately.

以上より、建方ヤードとなるフロアの階高に対して外壁材の長さが長い場合でも、外壁材取付け作業の作業効率を向上できる。   As described above, even when the length of the outer wall material is long with respect to the height of the floor serving as the building yard, the work efficiency of the outer wall material mounting work can be improved.

以上の外壁材取付システムは、前記外壁材の上側を支持して当該外壁材を前記所定フロア内で運搬可能な第2の台車をさらに備えることが好ましい。   The above outer wall material mounting system preferably further includes a second carriage that supports the upper side of the outer wall material and can transport the outer wall material within the predetermined floor.

この発明によれば、上述の台車で外壁材の下側を支持するとともに、第2の台車で外壁材の上側を支持して、外壁材を寝かせて略水平状態とする。そして、これら2台の台車を押して床端部まで運搬する。よって、外壁材を略水平状態に維持しながら水平方向に確実に運搬できる。   According to this invention, while supporting the lower side of an outer wall material with the above-mentioned trolley | bogie, the upper side of an outer wall material is supported with a 2nd trolley, and an outer wall material is laid down and it is set as a substantially horizontal state. And these two trolley | bogies are pushed and conveyed to a floor edge part. Therefore, the outer wall material can be reliably transported in the horizontal direction while maintaining the substantially horizontal state.

請求項に記載の外壁材取付システムは、前記所定フロアの床に設けられて当該床の端部から外側に跳ね出した跳ね出し部をさらに備え、前記台車は、当該跳ね出し部の上面を走行可能であることを特徴とする。 The outer wall material mounting system according to claim 1 , further comprising a jumping portion provided on the floor of the predetermined floor and jumping outward from an end portion of the floor, and the carriage has an upper surface of the jumping portion. It is possible to run.

外壁材を建て起こして上方に吊り上げる際、外壁材の上側は、揚重クレーンに吊り下げられて、建物の外壁面沿いつまり床端部に位置しているが、外壁材の下側は、下側支持台車に支持されているため、建物の外壁面よりも内側つまり床端部よりも内側に位置している。よって、外壁材を上方に吊り上げるタイミングと下側支持台車を床端部に向かって移動するタイミングとを同期させないと、外壁材や揚重クレーンが建物に接触して損傷するおそれがあった。   When the outer wall material is erected and lifted upward, the upper side of the outer wall material is suspended by the lifting crane and is located along the outer wall surface of the building, that is, at the floor edge, but the lower side of the outer wall material is the lower side. Since it is supported by the side support carriage, it is located inside the outer wall surface of the building, that is, inside the floor edge. Therefore, if the timing for lifting the outer wall material upward and the timing for moving the lower support carriage toward the floor end are not synchronized, the outer wall material and the lifting crane may be in contact with the building and be damaged.

そこで、この発明によれば、床の端部から外側に跳ね出した跳ね出し部を設けた。よって、外壁材を建て起こして上方に吊り上げる際、この跳ね出し部の上面に台車を走行させて、床の外側まで台車を移動することで、外壁材をできる限り床の外側に位置させる。そして、この状態で揚重クレーンを巻上げて、外壁材を上方に吊り上げて建て起こす。よって、外壁材や揚重クレーンが建物に接触して損傷するのを確実に防止できる。また、このとき、把持部が後方に延びているため、作業員が跳ね出し部に接近せずに済み、作業の安全性がさらに向上する。   So, according to this invention, the protrusion part which protruded outside from the edge part of the floor was provided. Therefore, when the outer wall material is erected and lifted upward, the carriage is moved to the upper surface of the protruding portion and moved to the outside of the floor, thereby positioning the outer wall material as far as possible outside the floor. Then, in this state, the lifting crane is wound up, and the outer wall material is lifted upward and built up. Therefore, it can prevent reliably that an outer wall material and a lifting crane contact a building, and are damaged. At this time, since the grip portion extends rearward, the worker does not need to approach the spring-out portion, and the safety of the work is further improved.

また、揚重クレーンで外壁材の上側を支持する際、跳ね出し部の上面に第2の台車を走行させて、床の外側まで第2の台車を移動することで、外壁材をできる限り床の外側に位置させる。これにより、外壁材や揚重クレーンが建物に接触して損傷するのを確実に防止できる。   In addition, when supporting the upper side of the outer wall material with a lifting crane, the second carriage is moved to the outside of the floor by moving the second carriage on the upper surface of the protruding portion, so that the outer wall material can be moved to the floor as much as possible. It is located outside. Thereby, it can prevent reliably that an outer wall material and a lifting crane contact a building, and are damaged.

本発明の外壁材取付システムは、前記所定フロアには、前記床の端部を含む建方ヤードが区画され、前記外壁材は、当該建方ヤード内で仮置きされて、前記台車により運搬されることが好ましい In the outer wall material mounting system of the present invention, a building yard including an end of the floor is defined on the predetermined floor, and the outer wall material is temporarily placed in the building yard and is transported by the carriage. It is preferable .

この発明によれば、所定フロアに建方ヤードを区画した。よって、搬入した外壁材を一旦建方ヤードに集積しておき、その後、集積した外壁材を台車により建方ヤード内で運搬して吊り上げる。このように建方ヤード内で外壁材の取り扱いを行うので、外壁材取付け作業の安全性を確保できる。   According to this invention, the building yard is partitioned on the predetermined floor. Therefore, the loaded outer wall material is once accumulated in the building yard, and then the accumulated outer wall material is transported and lifted in the building yard by a carriage. Since the outer wall material is handled in the building yard in this way, the safety of the outer wall material mounting operation can be ensured.

請求項に記載の外壁材取付システムは、前記台車の車輪は、進行方向に沿って2列に配置され、前記跳ね出し部は、前記所定フロアの床に設けられて互いに略平行に延びる一対の平版状の延出部と、当該延出部の側端に立設された壁部と、を備え、前記一対の延出部のそれぞれの上面には、前記台車の各列の車輪が走行可能であり、前記壁部は、前記台車の各列の車輪を案内することを特徴とする。 The outer wall material mounting system according to claim 1 , wherein the wheels of the carriage are arranged in two rows along the traveling direction, and the jumping portions are provided on the floor of the predetermined floor and extend substantially parallel to each other. A plano-shaped extending portion and a wall portion standing on the side end of the extending portion, and wheels of each row of the carriage run on the upper surfaces of the pair of extending portions. The wall portion guides wheels of each row of the carriage.

この発明によれば、台車の車輪を2列とし、この2列の車輪に合わせて延出部を一対設けたので、台車の製作コストを低減できる。
壁部を設けて台車の車輪を案内させたので、台車が跳ね出し部から脱落するのを確実に防止できる。
According to this invention, since the wheels of the carriage are arranged in two rows and a pair of extending portions are provided in accordance with the two rows of wheels, the production cost of the carriage can be reduced.
Since the wall portion is provided to guide the wheels of the carriage, it is possible to reliably prevent the carriage from falling off the protruding portion.

以上の外壁材取付システムは、前記台車に設けられて当該台車の幅方向を回転軸として回転可能に吊り下げ支持されたストッパをさらに備えることが好ましい。   It is preferable that the outer wall material mounting system described above further includes a stopper that is provided on the carriage and supported so as to be rotatable around the width direction of the carriage.

この発明によれば、ストッパの下端を前方に振り上げた状態で、作業員が把持部を押して台車を前進させる。そして、外壁材の建て起こし作業を行う際には、ストッパを回転させて床面に立てておく。これにより、台車が移動するのを規制できるから、外壁材の建て起こし作業の安全性をより向上できる。   According to this invention, an operator pushes the grip portion and moves the carriage forward while the lower end of the stopper is swung forward. Then, when performing the work of erection of the outer wall material, the stopper is rotated to stand on the floor surface. Thereby, since a movement of a trolley | bogie can be controlled, the safety of the erection work of an outer wall material can be improved more.

本発明によれば、外壁材の下端縁を台車の上に載せて、この台車で外壁材の下端縁を支持し、さらに台車本体から後方かつ上方に延びる把持部を設けた。
よって、台車を前進や停止させる際、作業員が把持部を把持することで、従来のようにかがんだ姿勢で操作する必要がなく、立った姿勢で台車を操作できるので、作業員の負担を軽減して、外壁材の移動を精度良く制御できる。また、把持部が後方に延びているため、作業員が床の端部から離れることができ、作業の安全性が向上する。また、外壁材を建て起こす際、外壁材の下端縁を台車の上に載せた状態で建て起こす。よって、従来のように外壁材の下端縁を端太角材の上に載せて建て起こす場合に比べて、作業員の踏ん張りが効くから、台車を確実に操作できる。
また、外壁材を建て起こす際に外壁材の自重により台車が床の外側に向かって引っ張られても、作業員は、把持部により台車を直接的に操作できるので、従来のように介助ロープを引っ張って台車を間接的に操作する場合に比べて、外壁材を安全かつ精度良く制御できる。以上より、建方ヤードとなるフロアの階高に対して外壁材の長さが長い場合でも、外壁材取付け作業の作業効率を向上できる。
According to the present invention, the lower end edge of the outer wall member is placed on the carriage, the lower end edge of the outer wall member is supported by the carriage, and the grip portion extending rearward and upward from the carriage body is provided.
Therefore, when the carriage is moved forward or stopped, it is not necessary for the worker to operate in a leaning posture by gripping the gripping part, and the cart can be operated in a standing posture. The movement of the outer wall material can be controlled with high accuracy. Moreover, since the holding | gripping part is extended back, an operator can leave | separate from the edge part of a floor, and the safety | security of work improves. Moreover, when building up the outer wall material, the lower wall edge of the outer wall material is built up in a state of being placed on the carriage. Therefore, compared with the conventional case where the lower end edge of the outer wall material is placed on the end thick square member and built up, the operator's struts are effective, so that the cart can be operated reliably.
Also, even when the trolley is pulled toward the outside of the floor due to the weight of the outer wall material when the outer wall material is erected, the operator can operate the trolley directly with the gripping part, so that the support rope can be Compared to the case where the carriage is indirectly operated by pulling, the outer wall material can be controlled safely and accurately. As described above, even when the length of the outer wall material is long with respect to the height of the floor serving as the building yard, the work efficiency of the outer wall material mounting work can be improved.

以下、建方ヤード15において、外壁材20を床端部まで運搬して揚重クレーン60で吊り上げる手順について説明する。   Hereinafter, in the construction yard 15, a procedure for transporting the outer wall material 20 to the floor end and lifting it with the lifting crane 60 will be described.

まず、図1および図2に示すように、上側支持台車40に外壁材20の上側を支持させ、下側支持台車30に外壁材20の下側を支持させて、外壁材20を略水平に寝かせた状態とする。
次に、上側支持台車40に作業員71を割り当て、下側支持台車30に作業員70を割り当てて、これら2名の作業員70、71で台車30、40を押して跳ね出し部50の設けられた床端部まで外壁材20を運搬して、上側支持台車40を床端部に配置する。このとき、下側支持台車30の作業員70は、把持部32の把持フレーム322を把持して下側支持台車30を押す。
First, as shown in FIGS. 1 and 2, the upper support carriage 40 supports the upper side of the outer wall member 20, and the lower support carriage 30 supports the lower side of the outer wall member 20, so that the outer wall member 20 is substantially horizontal. Let it lie down.
Next, the worker 71 is assigned to the upper support carriage 40, the worker 70 is assigned to the lower support carriage 30, and the two workers 70 and 71 push the carriages 30 and 40 to provide the jumping portion 50. The outer wall material 20 is transported to the floor end, and the upper support carriage 40 is arranged at the floor end. At this time, the operator 70 of the lower support carriage 30 presses the lower support carriage 30 by holding the holding frame 322 of the holding portion 32.

次に、延長安全帯61を用いて上側支持台車40および下側支持台車30を操作する作業員70、71の安全を確保し、床端部近傍の垂直ネット17を捲り上げる。   Next, the safety of the workers 70 and 71 who operate the upper support cart 40 and the lower support cart 30 using the extended safety belt 61 is secured, and the vertical net 17 near the floor end is lifted up.

次に、揚重クレーン60の吊りフック62を跳ね出し部50の直上に位置させ、建物10の外壁面沿い下ろす。
そして、外壁材20の上側を支持している上側支持台車40を床端部の跳ね出し部50に向かって前進させる。そして、上側支持台車40を跳ね出し部50の上面に走行させて、床端部の外側まで上側支持台車40を移動して、外壁材20をできる限り床14の外側に位置させる。
その後、図3に示すように、揚重クレーン60の吊りフック62を、ワイヤ63を介して外壁材20の上側に連結し、揚重クレーン60で外壁材20を支持した後、外壁材20の上側を支持していた上側支持台車40を取り外す。
Next, the suspension hook 62 of the lifting crane 60 is positioned immediately above the jumping portion 50 and lowered along the outer wall surface of the building 10.
Then, the upper support carriage 40 supporting the upper side of the outer wall material 20 is advanced toward the protruding portion 50 at the floor end. Then, the upper support carriage 40 is caused to travel on the upper surface of the spring-out portion 50, and the upper support carriage 40 is moved to the outside of the floor end portion so that the outer wall member 20 is positioned as far as possible outside the floor 14.
After that, as shown in FIG. 3, the hanging hook 62 of the lifting crane 60 is connected to the upper side of the outer wall member 20 via the wire 63, and after supporting the outer wall member 20 with the lifting crane 60, The upper support carriage 40 that supported the upper side is removed.

次に、図4に示すように、揚重クレーン60を巻き上げて、外壁材20を上方に吊り上げるとともに、外壁材20の下側を支持している下側支持台車30を床端部の跳ね出し部50に向かって前進させる。そして、下側支持台車30を跳ね出し部50の上面に走行させて、床端部の外側まで下側支持台車30を移動して、外壁材20をできる限り床14の外側に位置させる。
その後、さらに揚重クレーン60を巻上げて、外壁材20を上方に吊り上げるとともに下側支持台車30を取り外して、外壁材20を鉛直状態とする。
Next, as shown in FIG. 4, the lifting crane 60 is wound up, the outer wall material 20 is lifted upward, and the lower support cart 30 supporting the lower side of the outer wall material 20 is ejected from the floor end. Advance toward part 50. Then, the lower support carriage 30 is caused to travel on the upper surface of the protruding portion 50, and the lower support carriage 30 is moved to the outside of the floor end portion so that the outer wall material 20 is positioned as far as possible outside the floor 14.
Thereafter, the lifting crane 60 is further wound up, the outer wall material 20 is lifted upward, and the lower support cart 30 is removed to bring the outer wall material 20 into a vertical state.

本実施形態によれば、以下のような効果がある。
(1)外壁材20の下端縁を下側支持台車30の上に載せて、この下側支持台車30で外壁材20の下端縁を支持し、さらに台車本体31から後方かつ上方に延びる把持部32を設けた。
よって、下側支持台車30を前進や停止させる際、作業員が把持部32を把持することで、従来のようにかがんだ姿勢で操作する必要がなく、立った姿勢で下側支持台車30を操作できるので、作業員70の負担を軽減して、外壁材20の移動を精度良く制御できる。
また、把持部32が後方に延びているため、作業員が床14の端部から離れることができ、作業の安全性が向上する。
According to this embodiment, there are the following effects.
(1) The lower end edge of the outer wall material 20 is placed on the lower support carriage 30, the lower support carriage 30 supports the lower end edge of the outer wall material 20, and the grip portion extends rearward and upward from the carriage body 31. 32 was provided.
Therefore, when the lower support cart 30 is moved forward or stopped, the operator does not need to operate in a bent posture as in the prior art by gripping the grip portion 32, and the lower support cart 30 can be operated in a standing posture. Since it can be operated, the burden on the worker 70 can be reduced and the movement of the outer wall material 20 can be accurately controlled.
Moreover, since the holding | gripping part 32 is extended back, a worker can leave | separate from the edge part of the floor 14, and the safety | security of work improves.

また、外壁材20を建て起こす際、外壁材20の下端縁を下側支持台車30の上に載せた状態で建て起こす。よって、従来のように外壁材の下端縁を端太角材の上に載せて建て起こす場合に比べて、作業員70の踏ん張りが効くから、下側支持台車30を確実に操作できる。
また、外壁材20を建て起こす際に外壁材20の自重により下側支持台車30が床14の外側に向かって引っ張られても、作業員70は、把持部32により下側支持台車30を直接的に操作できるので、従来のように介助ロープを引っ張って台車を間接的に操作する場合に比べて、外壁材20の建て起こしを安全かつ精度良く制御できる。
Further, when the outer wall material 20 is erected, the outer wall material 20 is erected in a state where the lower end edge of the outer wall material 20 is placed on the lower support carriage 30. Therefore, as compared with the conventional case where the lower end edge of the outer wall material is placed on the thick end square member and built up, the operator 70 is more strutable, so that the lower support carriage 30 can be operated reliably.
Further, even when the lower support cart 30 is pulled toward the outside of the floor 14 by the weight of the outer wall material 20 when the outer wall material 20 is erected, the worker 70 directly moves the lower support cart 30 by the grip portion 32. Therefore, the erection of the outer wall material 20 can be controlled safely and accurately as compared with the case where the cart is indirectly operated by pulling the assistance rope as in the prior art.

以上より、建方ヤード15となるフロア11Aの階高に対して外壁材20の長さが長い場合でも、外壁材取付け作業の作業効率を向上できる。   From the above, even when the length of the outer wall material 20 is longer than the height of the floor 11A serving as the building yard 15, the work efficiency of the outer wall material mounting work can be improved.

(2)下側支持台車30で外壁材20の下側を支持するとともに、上側支持台車40で外壁材20の上側を支持して、外壁材20を寝かせて略水平状態とする。そして、これら2台の台車30、40を押して床14の端部まで運搬する。よって、外壁材20を略水平状態に維持しながら水平方向に確実に運搬できる。   (2) The lower support cart 30 supports the lower side of the outer wall material 20 and the upper support cart 40 supports the upper side of the outer wall material 20 and lays the outer wall material 20 in a substantially horizontal state. Then, the two carriages 30 and 40 are pushed and transported to the end of the floor 14. Therefore, the outer wall material 20 can be reliably transported in the horizontal direction while maintaining the substantially horizontal state.

(3)床14の端部から外側に跳ね出した跳ね出し部50を設けた。よって、外壁材20を建て起こして上方に吊り上げる際、この跳ね出し部50の上面に下側支持台車30を走行させて、床14の外側まで下側支持台車30を移動することで、外壁材20をできる限り床14の外側に位置させる。そして、この状態で揚重クレーン60を巻上げて、外壁材20を上方に吊り上げて建て起こす。よって、外壁材20や揚重クレーン60が建物10に接触して損傷するのを確実に防止できる。また、このとき、把持部32が後方に延びているため、作業員70が跳ね出し部50に接近せずに済み、作業の安全性がさらに向上する。   (3) A protruding portion 50 that protrudes outward from the end of the floor 14 is provided. Therefore, when the outer wall material 20 is erected and lifted upward, the lower support cart 30 is moved to the outside of the floor 14 by running the lower support cart 30 on the upper surface of the protruding portion 50, so that the outer wall material is moved. 20 as far as possible outside the floor 14. In this state, the lifting crane 60 is wound up, and the outer wall material 20 is lifted upward and built up. Therefore, it can prevent reliably that the outer wall material 20 and the lifting crane 60 contact the building 10, and are damaged. At this time, since the grip portion 32 extends rearward, the worker 70 does not need to approach the spring-out portion 50, and the safety of work is further improved.

また、揚重クレーン60で外壁材20の上側を支持する際、跳ね出し部50の上面に上側支持台車40を走行させて、床の外側まで上側支持台車40を移動することで、外壁材20をできる限り床14の外側に位置させる。これにより、外壁材20や揚重クレーン60が建物10に接触して損傷するのを確実に防止できる。   Moreover, when supporting the upper side of the outer wall material 20 with the lifting crane 60, the upper wall 40 is moved to the outside of the floor by running the upper support vehicle 40 on the upper surface of the protruding portion 50, so that the outer wall material 20 is moved. As far as possible outside the floor 14. Thereby, it can prevent reliably that the outer wall material 20 and the lifting crane 60 contact the building 10, and are damaged.

(4)フロア11Aに建方ヤード15を区画した。よって、搬入した外壁材20を一旦建方ヤード15に集積しておき、その後、集積した外壁材20を台車30、40により建方ヤード15内の跳ね出し部50まで運搬して取り付ける。このように建方ヤード15内で外壁材20の取り扱いを行うので、外壁材取付け作業の安全性を確保できる。   (4) The building yard 15 was partitioned on the floor 11A. Therefore, the loaded outer wall material 20 is once accumulated in the building yard 15, and then the accumulated outer wall material 20 is transported and attached to the jumping portion 50 in the building yard 15 by the carriages 30 and 40. Thus, since the outer wall material 20 is handled in the building yard 15, the safety of the outer wall material mounting operation can be ensured.

(5)下側支持台車30の車輪312を2列とし、この2列の車輪312に合わせて延出部51を一対設けたので、下側支持台車30の製作コストを低減できる。
壁部52を設けて下側支持台車30の車輪312を案内させたので、下側支持台車30が跳ね出し部50から脱落するのを確実に防止できる。
(5) Since the wheels 312 of the lower support carriage 30 are arranged in two rows and a pair of extending portions 51 are provided in accordance with the two rows of wheels 312, the manufacturing cost of the lower support carriage 30 can be reduced.
Since the wall portion 52 is provided to guide the wheels 312 of the lower support carriage 30, it is possible to reliably prevent the lower support carriage 30 from falling off the protruding portion 50.

なお、本発明は前記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
例えば、図5(a)に示すように、さらにストッパ33を設けて下側支持台車30Aとしてもよい。具体的には、ストッパ33は、把持フレーム322に回転可能に吊り下げ支持されており、これにより、ストッパ33は下側支持台車30Aの幅方向を回転軸として回転可能である。
It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, as shown in FIG. 5A, a stopper 33 may be further provided as the lower support cart 30A. Specifically, the stopper 33 is rotatably supported by the gripping frame 322, so that the stopper 33 can rotate about the width direction of the lower support carriage 30A as a rotation axis.

このようにすれば、ストッパ33の下端を前方に振り上げた状態で、作業員が把持部32を押して下側支持台車30Aを前進させる。そして、外壁材20の建て起こし作業を行う際には、図5(b)に示すように、ストッパ33を回転させて床面に立てて、下側支持台車30Aの後輪を浮かせておく。これにより、下側支持台車30Aが移動するのを規制できるから、外壁材20の建て起こし作業の安全性をより向上できる。   If it does in this way, in the state where the lower end of stopper 33 was swung up ahead, an operator pushes grasping part 32 and advances lower support cart 30A. Then, when the erection work of the outer wall material 20 is performed, as shown in FIG. 5B, the stopper 33 is rotated and stood on the floor, and the rear wheel of the lower support cart 30A is allowed to float. Thereby, since it can control that lower side support cart 30A moves, the safety of erection work of outer wall material 20 can be improved more.
