Description

【０００１】
【発明の属する技術分野】
本発明は、鉄骨または鉄骨コンクリート造の建築、その他の構造物を構築する建設工事において、柱鉄骨を建込むために、垂直もしくはこれに近い状態で立ち上がらせる作業を行うのに使用する柱鉄骨の建方装置および方法に関するものである。
【０００２】
【従来の技術】
柱鉄骨を建込みのもっとも一般的に行われている方法を図７〜図９にて示すと、まず、図７に示すように、三角形の末広がり脚部１４ａを有する固定架台１４を適宜な間隔で配置し、その上に柱鉄骨１２を載置して水平状態に支承しておく。そして、柱鉄骨１２の両側にクレーン１７を配置してこのクレーン１７で柱鉄骨両端部に設けたワイヤーフック１３をそれぞれワイヤー１５を介して吊り上げ、水平状態で浮かして固定架台１４から外す。
【０００３】
次いで、図８に示すように柱鉄骨１２の一方のクレーン１７で吊支したワイヤーフック１３を高く吊り上げ、他方のワイヤーフック１３の部分と高低差をつける。こうすることにより柱鉄骨１２を地面に対して徐々に斜めに傾ける。柱鉄骨１２を垂直に近い状態まで吊り上げたら、下端側になったワイヤーフック１３からワイヤー１５をはずし、図９に示すように上端側のワイヤーフック１３のみをワイヤー１５にて吊り上げることで、柱鉄骨１２を完全に垂直に立ち上げる。
【０００４】
一方、柱を建方するための発明としてクレーンを設置出来ないような狭い場所に柱を建てるものも提案されている。例えば、特願平１１- ２０１０２９号（特開２００１−２７０４５号公報）では図１０に示すように、フォークリフトをベースマシンとした自走台車１８の前部に、建方すべき柱１９を起立させた状態で昇降自在に保持する保持機構２０を備えた柱建方装置を使用し、柱１９のワイヤーフック１３をワイヤー１５によりクレーンフック１６と接続し、クレーンにより柱１９を吊り上げることでほぼ垂直状態まで起立させてそれを保持機構２０により保持する。保持機構２０は前後方向への若干の起倒が可能であり、これにより柱１９を完全に垂直な状態にする。垂直状態となった柱１９を保持機構２０で持ち上げ、柱建設位置まで移動させる。
【０００５】
【発明が解決しようとする課題】
前記図７〜図９に示した従来最も多く行われている柱鉄骨の建方方法では、クレーンを２機使用することになり、このため、機材を多く必要とするだけでなく、クレーン２機が設置できるだけの広い場所の確保も必要となる。また、２機のクレーンを同時に操作する必要があるので、クレーン操作に熟練した手腕が問われ、危険も多い。
【０００６】
また、特開２００１−２７０４５号公報の柱建方装置および柱建方方法では、まず柱をほぼ垂直状態まで起立させる必要があり、それには従来のクレーンを２機使用する方法を必要とする。さらに複雑な機構の柱建方装置が必要であり、また柱を立て起してから柱の場所を移動させるため、作業手順数が増えてしまう。
【０００７】
本発明の目的は前記従来例の不都合を解消し、クレーンが１機でも、安全にかつ容易に柱鉄骨を垂直もしくはこれに近い状態で立ち上げることができる柱鉄骨の建方装置および方法を提供することにある。
【０００８】
【課題を解決するための手段】
本発明は前記目的を達成するため、回転架台として、接地用の枠組み基部に左右支柱を立設し、その先端の軸受けで柱鉄骨の受け梁材を回転自在に支承し、この受け梁材に、受け梁材に直交して取り付ける水平アーム材とこの水平アーム材の端に立ち上げる垂直支持部材としての枠体からなり、水平アーム材は垂直支持部材立上げ側端と反対側の端を支柱より外側に突出させた柱受部を取り付け、支柱と柱受部にピン挿通孔を設け、支柱に柱受部が水平になる位置で、ピン挿通孔同士にピンを差し入れるようにしたことを要旨とするものである。
【０００９】
請求項１記載の発明によれば、柱鉄骨は地上に水平状態で載置するが、その際上端側を固定架台で支持し、下端部側面を本発明装置の受け梁材で支承し、また柱受部に柱鉄骨下端面を当接しておく。柱鉄骨に下端にベースプレートが接合されている場合は柱受部に当接するのはこのベースプレート裏面になる。これら梁材および柱受部は軸受けにて回転自在であるため、柱鉄骨の角度に合わせて回転可能であるので、固定架台側の柱鉄骨端をワイヤーで吊り上げ、同時に回転架台の回転部で柱鉄骨端を支承する状態で、柱鉄骨を垂直もしくはこれに近い状態で立ち上がらせることができる。
【００１０】
また、前記作用に加えて、柱受部は、受け梁材に直交して取り付ける水平アーム材とこの水平アーム材の端に立ち上げる垂直支持部材としての枠体からなることで、受け梁材と垂直支持部材間に空所が確保できてベースプレートの出っ張り分を受け入れることができる。また、柱受部は枠体により構成されるため、簡潔かつ軽量であり、かつ確実に柱鉄骨下端面を受け止めることができる。
【００１１】
水平アーム材の垂直支持部材立上げ側端と反対側の端を支柱より外側に突出させたことでこの部分が水平アーム材部のバランサーとなり、水平アーム材部が急激に回転してしまうことを防止できる。
【００１２】
さらに、支柱と柱受部に設けたピン挿通孔同士にピンを差し入れることで支柱に対し柱受部が水平となる位置での固定が可能であり、梁材および柱受部が不用意に回転するのを防ぎ、安定性を確保できる。
【００１３】
【発明の実施の形態】
以下、図面について本発明の実施の形態を詳細に説明する。図１は本発明の柱鉄骨の建方装置の１実施形態を示す正面図、図２は同上側面図、図３は同上平面図で、図中１は接地用の土台部としての枠組み基部である。
【００１４】
この枠組み基部１は地面に柱鉄骨の建方装置を設置したとき、地面に接する部分で、本実施形態では同じ長さのＨ形鋼を長短２本ずつ２組を組んだ長方形の枠体である。図２および図３で示すように枠組み基部１は縦横に適度な長さを持ち、柱鉄骨の建方装置に柱鉄骨を載置しても、地面に対して安定しているようになっている。これにより、柱鉄骨の建方作業を行う際に、柱鉄骨の建方装置は地面に対して固置され、安全に作業ができる。
【００１５】
枠組み基部１の長手方向の部材の中央に支柱２を立ち上げ、その先端にベアリングを介在させた軸受け（ピローブロック）３を設け、この軸受け３で受け梁材５からの回転軸４を軸支した。支柱２は枠組み基部１の左右で立設され、受け梁材５は形鋼を利用したもので、枠組み基部１の短長方向に掛渡され、軸受け３を介して回転自在に支承されるものである。
【００１６】
受け梁材５の上面には、柱鉄骨の径に見合う間隔を存して垂直壁面６ａを対向させた受け止め６をボルト等で着脱自在に設ける。該受け止め６はブロック材として鋼材で形成する。
【００１７】
この受け梁材５に、端部に垂直支持部材２１を立ち上げた柱受部７を取り付ける。この柱受部７は前記受け梁材５に直交して下面側に取り付ける水平アーム材８とこの水平アーム材８の端に立ち上げる垂直支持部材２１としてのコの字形またはロの字形の枠体からなる。
【００１８】
前記水平アーム材８も形鋼材を使用し、受け梁材５の下面に溶接またはボルト止め等で固設するが、前記垂直支持部材２１を立上げた側の端と反対側の端を支柱２の位置より外側に突出させてバランサー部９とした。バランサー部９は支柱２に対してバランサー部９と反対側の水平アーム材８や柱受部７との重量バランスをとるためのものであり、バランサー部９を設けることで、柱鉄骨の建方装置を静置したときに、柱受部７は支柱２に対して前後のバランスがとれ、垂直支持部材２１側の荷重で急激に回転してしまうことを防止できる。
【００１９】
支柱２にはピン挿通孔１０を穿設し、図は省略するが、柱受部７の水平アーム材８にもピン挿通孔を設け、これらピン挿通孔は支柱２に対して柱受部７が水平状態になったときに位置が一致するようにした。
【００２０】
前記ピン挿通孔同士が一致した状態で支柱２のピン挿通孔１０から挿入するピン１１を準備するが、このピン１１は鎖２２で支柱２側に繋ぎ、遺失を防いでいる。
【００２１】
ピン挿通孔にピン１１を挿入することで、柱鉄骨置載部と土台部の相互位置を固定することができる。これは柱鉄骨の建方装置を輸送するときや、作業中に柱鉄骨置載部が不用意に土台部に対して回転することを防ぐものである。これにより安全に柱鉄骨の建方装置を使用することができる。ピン１１を抜けば、柱鉄骨置載部と土台部は再び回転自在となる。
【００２２】
次に前記柱鉄骨の建方装置を用いて行う柱鉄骨の建方方法について説明する。図４〜図６は本発明の柱鉄骨の建方方法の各工程を示す側面図で、まず図４に示すように、一方に固定架台１４を、他方に本発明の柱鉄骨の建方装置を配置し、柱鉄骨１２を水平に支承する。なお固定架台１４を配置する側が柱鉄骨１２の上端、柱鉄骨の建方装置を配置する側が下端となるようにする。
【００２３】
固定架台１４は柱鉄骨１２を水平になるように支承するものであり、特別な装置である必要はなく、前記従来例の図７に示したものと同じで三角形の末広がり脚部１４ａを有するものでよい。固定架台１４の高さは柱鉄骨の建方装置の受け梁材５の高さとほぼ同じであり、柱鉄骨１２を支承することが可能なものなら、材料等も特に限定するものではない。柱鉄骨の建方装置はピン１１により柱鉄骨置載部と土台部の相互位置を固定しておくものとする。
【００２４】
本発明の柱鉄骨の建方装置で柱鉄骨１２の一端を支承するにあたり、柱鉄骨１２を受け梁材５の受け止め６の間に収まるようにして、受け梁材５で柱鉄骨１２の下端部側面を支承し、また柱受部７の垂直支持部材２１に柱鉄骨１２の下端面を当接しておく。
【００２５】
図４に示すように、柱鉄骨１２の下端にはベースプレート１２ａが存在するが、このような場合にも、受け梁材５と水平アーム材８を段差をつけて接合することにより受け梁材５と垂直支持部材２１間に空所が確保できてここでベースプレート１２ａの出っ張り分を受け入れることができる。
【００２６】
次に図５に示すように、柱鉄骨１２に設けたワイヤーフック１３をワイヤー１５によりクレーンフック１６と接続する。クレーンによりクレーンフック１６を引き上げ、ワイヤーフック１３を吊り上げる。ワイヤーフック１３は柱鉄骨１２の上端部に存在するため、柱鉄骨１２の上端を吊り上げることとなる。その際、ピン１１は抜いておく。
【００２７】
上端を吊り上げるにつれ、柱鉄骨１２は地面に対しての傾きを増していく。それに従い、受け梁材５を中心に柱鉄骨の建方装置の柱鉄骨置載部は回転し、柱鉄骨１２の傾きに対応する。
【００２８】
図６に示されるように、柱鉄骨１２が垂直状態になるまでクレーンフック１６を吊り上げる。さらにクレーンフック１６を吊り上げることで、柱鉄骨１２の下端面は柱受部７から離れ、垂直状態で完全に浮上する。この状態でクレーンにより柱鉄骨１２を本来建込む位置に移動させる。
【００２９】
【発明の効果】
以上述べたように本発明の柱鉄骨の建方装置は、クレーンが１機でも、安全にかつ容易に柱鉄骨を垂直もしくはこれに近い状態で立ち上げることができるものである。

BACKGROUND OF THE INVENTION
The present invention relates to the construction of a column steel frame used for the work of standing up in a vertical or near state in order to build a column steel frame in a construction work for constructing a steel frame or a steel concrete structure or other structure. The present invention relates to a construction apparatus and method.
[0002]
[Prior art]
7 to 9 show the most commonly used method of erection of the column steel frame. First, as shown in FIG. 7, the fixed base 14 having the triangular divergent legs 14a is appropriately spaced. The column steel frame 12 is placed thereon and supported in a horizontal state. And the crane 17 is arrange | positioned on both sides of the column steel frame 12, and the wire hook 13 provided in the column steel frame both ends with this crane 17 is lifted via the wire 15, respectively, floats in a horizontal state, and removes from the fixed mount 14.
[0003]
Next, as shown in FIG. 8, the wire hook 13 suspended by one crane 17 of the pillar steel frame 12 is lifted high, and a height difference is made from the portion of the other wire hook 13. By doing so, the column steel frame 12 is gradually inclined with respect to the ground. When the column steel frame 12 is lifted to a nearly vertical state, the wire 15 is removed from the wire hook 13 on the lower end side, and only the wire hook 13 on the upper end side is lifted with the wire 15 as shown in FIG. Start up 12 completely vertically.
[0004]
On the other hand, as an invention for constructing a pillar, there is also proposed a construction in which a pillar is built in a narrow place where a crane cannot be installed. For example, in Japanese Patent Application No. 11-201029 (Japanese Patent Laid-Open No. 2001-27045), as shown in FIG. 10, a pillar 19 to be erected is raised at the front of a self-propelled carriage 18 using a forklift as a base machine. The column construction apparatus provided with the holding mechanism 20 that can be moved up and down in a tilted state is used, the wire hook 13 of the column 19 is connected to the crane hook 16 by the wire 15, and the column 19 is lifted by the crane to be almost vertical. And hold it by the holding mechanism 20. The holding mechanism 20 can be slightly raised and lowered in the front-rear direction, thereby bringing the column 19 into a completely vertical state. The column 19 in the vertical state is lifted by the holding mechanism 20 and moved to the column construction position.
[0005]
[Problems to be solved by the invention]
7 to 9, the most commonly used method for constructing pillar steel frames requires two cranes. Therefore, not only a lot of equipment is required, but two cranes are used. It is also necessary to secure a large space that can be installed. In addition, since it is necessary to operate two cranes at the same time, the skill of crane operation is required, and there are many dangers.
[0006]
Further, in the column building apparatus and column building method disclosed in Japanese Patent Laid-Open No. 2001-27045, it is necessary to first erect the column to a substantially vertical state, which requires a method of using two conventional cranes. Furthermore, a column construction apparatus having a complicated mechanism is required, and the number of work procedures increases because the location of the column is moved after raising the column.
[0007]
An object of the present invention is to provide a column steel frame construction apparatus and method that can eliminate the disadvantages of the conventional example and can safely and easily start up a column steel frame vertically or close to it even with a single crane. There is to do.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention, as a rotating mount, has left and right support columns upright on a grounding frame base, and rotatably supports a column steel receiving beam member with a bearing at its tip. The arm consists of a horizontal arm member that is mounted perpendicular to the receiving beam member and a frame as a vertical support member that rises at the end of the horizontal arm member. The horizontal arm member has a column on the opposite end to the vertical support member rising side end. A column receiving part that protrudes more outward is installed, and a pin insertion hole is provided in the column and the column receiving part, and the pin is inserted between the pin insertion holes at a position where the column receiving part is horizontal to the column. It is a summary.
[0009]
According to the first aspect of the present invention, the column steel frame is placed in a horizontal state on the ground. At this time, the upper end side is supported by the fixed base, the lower end side surface is supported by the receiving beam material of the device of the present invention, and The lower end surface of the column steel frame is brought into contact with the column receiving portion. When the base plate is joined to the lower end of the column steel frame, it is the back surface of the base plate that comes into contact with the column receiving portion. Since these beam members and column bearings can be rotated by bearings, they can be rotated according to the angle of the column steel frame, so the column steel end on the fixed frame side is lifted with a wire, and at the same time the column is rotated by the rotation unit of the rotation frame. The column steel frame can be made to stand upright or close to the state in which the steel frame end is supported.
[0010]
Further, in addition to the above action, the column receiving portion is composed of a horizontal arm material that is attached orthogonal to the receiving beam material and a frame as a vertical support member that rises at the end of the horizontal arm material. A space can be secured between the vertical support members, and the protruding portion of the base plate can be received. Moreover, since the column receiving portion is constituted by a frame, it is simple and lightweight, and can reliably receive the lower end surface of the column steel frame.
[0011]
By projecting the end of the horizontal arm material opposite the vertical support member rising side end to the outside of the column, this part becomes a balancer of the horizontal arm material part, and the horizontal arm material part suddenly rotates. Can be prevented.
[0012]
Furthermore, by inserting a pin between the pin insertion holes provided in the column and the column holder, it is possible to fix the column holder in a position where it is horizontal to the column, and the beam material and the column holder are inadvertent. Prevents rotation and secures stability.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of a pillar steel frame construction apparatus according to the present invention, FIG. 2 is a side view of the same, FIG. 3 is a plan view of the same, and 1 is a framework base as a grounding base part is there.
[0014]
This frame base 1 is a portion in contact with the ground when a column steel frame construction device is installed on the ground. In this embodiment, the frame base 1 is a rectangular frame made up of two pairs of long and short H-shaped steel. is there. As shown in FIG. 2 and FIG. 3, the frame base 1 has an appropriate length in the vertical and horizontal directions, and even when the column steel frame is placed on the column steel frame construction device, it is stable with respect to the ground. Yes. Thereby, when performing the construction work of the column steel frame, the column steel frame construction apparatus is fixed to the ground and can be safely operated.
[0015]
A support column 2 is set up at the center of the longitudinal member of the frame base 1 and a bearing (pillow block) 3 with a bearing interposed at its tip is provided. The bearing 3 supports the rotating shaft 4 from the receiving beam member 5. did. The support column 2 is erected on the left and right sides of the frame base 1, and the receiving beam material 5 is made of steel and is stretched in the short length direction of the frame base 1 and is rotatably supported via the bearing 3. It is.
[0016]
On the upper surface of the receiving beam member 5, a receiving member 6, which is opposed to the vertical wall surface 6 a with an interval corresponding to the diameter of the column steel frame, is detachably provided with a bolt or the like. The catch 6 is made of steel as a block material.
[0017]
A column receiving portion 7 having a vertical support member 21 raised at the end is attached to the receiving beam member 5. The column receiving portion 7 is a U-shaped or B-shaped frame body as a horizontal arm member 8 which is attached to the lower surface side orthogonal to the receiving beam member 5 and a vertical support member 21 which rises at the end of the horizontal arm member 8. Consists of.
[0018]
The horizontal arm member 8 is also made of steel and is fixed to the lower surface of the receiving beam member 5 by welding or bolting, but the end opposite to the side where the vertical support member 21 is raised is connected to the column 2. The balancer portion 9 was projected outward from the position. The balancer portion 9 is for balancing the weight of the horizontal arm member 8 and the column receiving portion 7 opposite to the balancer portion 9 with respect to the support column 2. By providing the balancer portion 9, how to build the column steel frame When the apparatus is left stationary, the column receiving portion 7 is balanced in the front-rear direction with respect to the column 2 and can be prevented from rotating suddenly due to the load on the vertical support member 21 side.
[0019]
Although the pin insertion hole 10 is drilled in the support column 2 and the illustration is omitted, the horizontal arm member 8 of the column receiving portion 7 is also provided with a pin insertion hole, and these pin insertion holes are formed in the column receiving portion 7 with respect to the support column 2. Aligned the position when the becomes horizontal.
[0020]
A pin 11 to be inserted from the pin insertion hole 10 of the support column 2 is prepared in a state where the pin insertion holes are aligned with each other. This pin 11 is connected to the support column 2 side by a chain 22 to prevent loss.
[0021]
By inserting the pin 11 into the pin insertion hole, the mutual position of the column steel frame mounting portion and the base portion can be fixed. This prevents the column steel frame mounting portion from rotating carelessly with respect to the base portion during transportation of the column steel frame construction device or during work. This makes it possible to safely use the column steel frame construction device. If the pin 11 is removed, the column steel frame mounting portion and the base portion become rotatable again.
[0022]
Next, a method for building a column steel using the column steel frame building apparatus will be described. 4 to 6 are side views showing the steps of the method for constructing a column steel frame according to the present invention. First, as shown in FIG. And the column steel frame 12 is supported horizontally. The side on which the fixed base 14 is arranged is the upper end of the column steel frame 12, and the side on which the column steel frame construction device is arranged is the lower end.
[0023]
The fixed base 14 supports the column steel frame 12 so as to be horizontal, and does not need to be a special device, and has the triangular end-spreading leg portion 14a similar to that shown in FIG. It's okay. The height of the fixed base 14 is substantially the same as the height of the receiving beam member 5 of the column steel frame construction device, and the material and the like are not particularly limited as long as the column steel frame 12 can be supported. It is assumed that the column steel frame construction apparatus fixes the position of the column steel frame mounting portion and the base portion with pins 11.
[0024]
In order to support one end of the column steel frame 12 with the column steel frame construction apparatus of the present invention, the lower end portion of the column steel frame 12 is received by the receiving beam material 5 so that the column steel frame 12 is received between the receiving members 6 of the beam material 5. The side surface is supported, and the lower end surface of the column steel frame 12 is brought into contact with the vertical support member 21 of the column receiving portion 7.
[0025]
As shown in FIG. 4, a base plate 12 a exists at the lower end of the column steel frame 12. Even in such a case, the receiving beam material 5 and the horizontal arm material 8 are joined to each other with a step difference. A space can be secured between the vertical support member 21 and the protruding portion of the base plate 12a can be received here.
[0026]
Next, as shown in FIG. 5, the wire hook 13 provided on the pillar steel frame 12 is connected to the crane hook 16 by the wire 15. The crane hook 16 is pulled up by the crane, and the wire hook 13 is lifted. Since the wire hook 13 exists at the upper end of the column steel frame 12, the upper end of the column steel frame 12 is lifted. At that time, the pin 11 is removed.
[0027]
As the upper end is lifted, the column steel frame 12 increases in inclination with respect to the ground. Accordingly, the column steel frame mounting portion of the column steel frame construction device rotates around the receiving beam member 5 to correspond to the inclination of the column steel frame 12.
[0028]
As shown in FIG. 6, the crane hook 16 is lifted until the pillar steel 12 is in a vertical state. Further, by lifting the crane hook 16, the lower end surface of the column steel frame 12 is separated from the column receiving portion 7 and completely floats in a vertical state. In this state, the column steel frame 12 is moved to a position where it is originally built by a crane.
[0029]
