Description

本発明は足場システムに係り、より詳しくは、所定の装備への取り付けに当たり、取り付け装置への異物の落下防止及び作業の便宜を図るために設けられる支持パネルを支える構造を改善して組立て及び撤去を容易に行うことのできる足場システムに関する。 The present invention relates to a scaffold system, and more particularly, in mounting to a predetermined equipment, assembling and removing by improving a structure for supporting a support panel provided to prevent foreign matter from falling on the mounting device and to facilitate work. It is related with the scaffold system which can perform easily.

通常、液化天然ガスは、メタンを主成分とする天然ガスを極低温の状態にしてその体積を圧縮したものであり、これを運搬するための輸送船は、液化天然ガスを貯蔵するタンクの断熱方式によって、独立型のものとメンブレン型のものとに大別できる。 Usually, liquefied natural gas is obtained by compressing the volume of natural gas mainly composed of methane at a very low temperature, and a transport ship for transporting this gas is a heat insulating tank for storing liquefied natural gas. Depending on the system, it can be broadly divided into independent type and membrane type.

前記輸送船における液化天然ガスの貯蔵タンクは、内部の断熱のためにその内壁に設けられるメンブレンが極めて薄く、その取付け高さが極めて大きくなっている。このため、前記貯蔵タンク及び周辺施設の取付け作業に際しては、前記貯蔵タンクへの異物の落下及び接触を防ぐ目的で、足場システムを構成してから作業を行っている。このような通常の足場システムは、図１に示してある。 The liquefied natural gas storage tank in the transport ship has a very thin membrane provided on its inner wall for heat insulation inside, and its mounting height is extremely large. For this reason, when attaching the storage tank and surrounding facilities, the scaffolding system is configured for the purpose of preventing the foreign matter from falling and contacting the storage tank. Such a typical scaffold system is shown in FIG.

図１は、通常の足場システムを示す斜視図である。 FIG. 1 is a perspective view showing a normal scaffold system.

図１を参照すると、液化天然ガスが貯えられる貯蔵タンク１に何らかの作業を行うための足場システムには、左右の両側部分と途中部分にそれぞれ足場支柱２が設けられる。これらの足場支柱２は、作業員の作業及び移動スペースに用いられる支持パネル５を取り付けるためのものであり、この支持パネル５は、前記足場支柱２に連ねるボードベア４により支えられる。また、前記足場支柱２には、作業員が移動または作業を行うときに空間をガイドして前記作業員を支えるためのガイドレール３が設けられる。前記ガイドレール３は、前記支持パネル５の上側に作業員をガイドまたは支持できる高さで、両端が隣り合う足場支柱２にそれぞれ固定される。 Referring to FIG. 1, a scaffold system for performing some work on a storage tank 1 in which liquefied natural gas is stored is provided with scaffolding struts 2 on both the left and right sides and in the middle. These scaffold struts 2 are for attaching a support panel 5 used for the work and movement space of the worker, and this support panel 5 is supported by a board bear 4 connected to the scaffold strut 2. The scaffolding strut 2 is provided with a guide rail 3 for guiding the space and supporting the worker when the worker moves or works. The guide rails 3 are fixed to the scaffolding struts 2 adjacent to each other at a height that can guide or support an operator on the upper side of the support panel 5.

図２(a)は、従来の技術による足場システムの支持パネルの底面図であり、図２(b)は、図２(a)におけるＩ−Ｉ線断面拡大図である。 FIG. 2A is a bottom view of a support panel of a conventional scaffold system, and FIG. 2B is an enlarged cross-sectional view taken along line II in FIG. 2A.

図２を参照すると、前記ボードベア４は、前記足場支柱２の一方の側と他方の側においてそれぞれ固定されて前記支持パネル５を支える。このために、前記一方の側と他方の側におけるボードベア（board bear）４の間には、上側に位置する支持パネル５を支えるための多数のフレーム６が挿置される。 Referring to FIG. 2, the board bear 4 is fixed on one side and the other side of the scaffold column 2 to support the support panel 5. For this purpose, a large number of frames 6 for supporting the support panel 5 located on the upper side are inserted between the board bears 4 on the one side and the other side.

このとき、前記フレーム６の先端には、前面と両側面が開口され、上面と下面にそれぞれ締結孔６ｂが形成されて全体としてコ字状を呈する締結部６ａが形成される。また、前記ボードベア４には、前記フレーム６が密接される一方の面に前記締結部６ａと結合する連結部４ａが形成される。この連結部４ａは、前面と両側面が端面を形成し、かつ、上面と下面が開口されたような形状を呈する。 At this time, the front surface and both side surfaces are opened at the front end of the frame 6, and fastening holes 6 b are formed on the upper surface and the lower surface, respectively, so that a fastening portion 6 a having a U-shape as a whole is formed. The board bear 4 is formed with a connecting portion 4a that is coupled to the fastening portion 6a on one surface to which the frame 6 is in close contact. The connecting portion 4a has a shape in which the front surface and both side surfaces form end surfaces, and the upper surface and the lower surface are opened.

このため、前記フレーム６における締結部６ａの開口された内側に前記連結部４ａが据付可能に、前記フレーム６を前記ボードベア４の一方の面に密接する。そして、前記締結部６ａの前面に形成されている締結孔にテーパーキー７ａを差し込み、このテーパーキー７ａを前記連結部４ａの開口面、すなわち、上下面に通させて前記締結部６ａの下面に突出させる。このように、前記テーパーキー７ａが前記連結部４ａと締結部６ａを固定することにより、前記フレーム６が前記ボードベア４に固定される。 For this reason, the frame 6 is brought into close contact with one surface of the board bear 4 so that the connecting portion 4a can be installed inside the opening of the fastening portion 6a in the frame 6. Then, a taper key 7a is inserted into a fastening hole formed in the front surface of the fastening portion 6a, and the taper key 7a is passed through the opening surface of the connecting portion 4a, that is, the upper and lower surfaces, and is placed on the lower surface of the fastening portion 6a. Make it protrude. In this manner, the frame 6 is fixed to the board bear 4 by the taper key 7a fixing the connecting portion 4a and the fastening portion 6a.

図３(a)及び図３(b)は、それぞれ図１におけるＡ部分及びＢ部分の拡大斜視図であり、従来の技術による足場システムの足場支柱連結装置にボードベア４またはガイドレール３が取り付けられている状態である。 3 (a) and 3 (b) are enlarged perspective views of part A and part B in FIG. 1, respectively, and the board bear 4 or the guide rail 3 is attached to the scaffold strut connecting device of the scaffold system according to the prior art. It is in a state.

図３を参照すると、従来の足場支柱連結装置には、前記足場支柱２の外周面に前記ガイドレール３またはボードベア４を取り付けるための連結金具２ａが溶接される。 Referring to FIG. 3, a connecting bracket 2 a for attaching the guide rail 3 or the board bear 4 to the outer peripheral surface of the scaffold column 2 is welded to the conventional scaffold column coupling device.

前記連結金具２ａは略コ字状に折り曲げられた部材であり、その両端部が前記足場支柱２に溶接される。これにより、前記連結金具２ａ及び前記足場支柱２により囲まれ、且つ、上側と下側が開口された貫通孔２ｂが形成される。 The connecting metal fitting 2a is a member bent in a substantially U shape, and both ends thereof are welded to the scaffold column 2. Thereby, the through-hole 2b surrounded by the connecting metal fitting 2a and the scaffolding column 2 and having an upper side and a lower side opened is formed.

このようにして形成される連結金具２ａは、図３(a)に示すように、前記足場支柱２の片側に設けられても良く、図３(b)に示すように、前記足場支柱２の前面と背面、そして両側にそれぞれ設けられても良い。 The connection fitting 2a formed in this way may be provided on one side of the scaffolding column 2 as shown in FIG. 3 (a), and the coupling bracket 2a of the scaffolding column 2 as shown in FIG. 3 (b). It may be provided on the front surface, the back surface, and both sides.

さらに、前記ガイドレール３または前記ボードベア４の両端にはそれぞれ、上側において平面を形成する上面プレート３ａ、４ａと、前記上面プレート３ａ、４ａと対向するような平面を形成する下面プレート３ｂ、４ｂとが形成され、前面は開口される。また、前記上面プレート３ａ、４ａ及び前記下面プレート３ｂ、４ｂには、それぞれの同一線上を貫通する挿入孔３ｃ、４ｃが形成される。 Further, at both ends of the guide rail 3 or the board bear 4 are upper surface plates 3a, 4a that form a plane on the upper side, and lower surface plates 3b, 4b that form a plane that faces the upper surface plates 3a, 4a, respectively. Is formed, and the front surface is opened. In addition, insertion holes 3c and 4c are formed in the upper surface plates 3a and 4a and the lower surface plates 3b and 4b so as to penetrate the same line.

一方、前記足場支柱の連結金具は、前記貫通孔２ｂの上、下側に前記ガイドレール３または前記ボードベア４の上面プレート３ａ、４ａと下面プレート３ｂ、４ｂの挿入孔３ｃ、４ｃがそれぞれ位置するように配設された状態で、前記貫通孔２ｂ及び前記挿入孔３ｃ、４ｃにテーパーキー７ｂ、７ｃが差し込まれる。 On the other hand, the connecting metal fittings for the scaffold struts are respectively provided with insertion holes 3c, 4c for the upper surface plates 3a, 4a and the lower surface plates 3b, 4b of the guide rail 3 or the board bear 4 above and below the through hole 2b. In such a state, the taper keys 7b and 7c are inserted into the through hole 2b and the insertion holes 3c and 4c.

前記テーパーキー７ｂ、７ｃは、先ず、その下側が前記前記プレート３ａ、４ａの挿入孔３ｃ、４ｃに挿入されて前記貫通孔２ｂを貫通した後、前記下プレート３ｂ、４ｂの挿入孔３ｃ、４ｃを通って突出され、これにより、前記足場支柱２と前記ガイドレール３または前記ボードベア４とが固定される。 The taper keys 7b and 7c are first inserted into the insertion holes 3c and 4c of the plates 3a and 4a through the through holes 2b, and then the insertion holes 3c and 4c of the lower plates 3b and 4b. The scaffolding strut 2 and the guide rail 3 or the board bear 4 are fixed.

このために、前記テーパーキー７ｂ、７ｃは、一方の側面が垂直端面を呈すると共に、他方の側面は下方に進むにつれて狭幅となる傾斜面を呈する。 For this reason, the taper keys 7b and 7c have one side surface having a vertical end surface and the other side surface having an inclined surface that becomes narrower as it goes downward.

しかしながら、上記の如き従来の足場システムは、前記フレームとボードベアをつなぐフレーム連結装置が別体のテーパーキーにより固定されるが故に、前記テーパーキーの紛失またはその数量の不足時には作業を行うことが困難になり、別途の管理が求められていた。また、従来の足場システムは、複数のガイドレールまたはボードベアの連結が容易ではなく、網などを別途に張る必要があるときには、別途の連結装置が必要とされていた。さらに、従来の足場システムは、前記ボードベアまたはガイドレールの連結のための連結金具が前記足場支柱に溶接されるが故に、取付け高さを変えることができず、しかも、他の足場支柱と同じ個所に連結金具を溶接する必要があるが故に、作業が決して容易ではなかった。なおかつ、溶接に起因して前記足場支柱と前記ボードベアまたはガイドレールとの連結部が熱的損傷を受けて変色が起こり、しかも、錆などが形成され、塗色を行う必要があるという不都合があった。加えて、従来の足場システムは、前記足場支柱とガイドレールまたはボードベアとの結合が堅固ではないため、振動または外力により前記テーパーキーが外されたり、締付力が弛まったりする恐れがあった。これにより、前記足場支柱からガイドレールまたはボードベアが離脱する可能性があり、これは、安全事故につながるという問題点があった。 However, in the conventional scaffold system as described above, the frame connecting device that connects the frame and the board bear is fixed by a separate taper key. As a result, separate management was required. Further, in the conventional scaffold system, it is not easy to connect a plurality of guide rails or board bears, and when a net or the like needs to be stretched separately, a separate connecting device is required. Further, the conventional scaffold system cannot change the mounting height because the connecting bracket for connecting the board bear or the guide rail is welded to the scaffold column, and the same place as the other scaffold columns. Since it was necessary to weld the connecting metal to the work, the work was never easy. In addition, due to welding, the connecting portion between the scaffold strut and the board bear or the guide rail is thermally damaged and discolored, and rust is formed, and it is necessary to perform coating. It was. In addition, in the conventional scaffold system, since the coupling between the scaffold column and the guide rail or the board bear is not firm, the taper key may be removed or the tightening force may be loosened due to vibration or external force. As a result, there is a possibility that the guide rail or the board bear may be detached from the scaffold column, which has a problem that it leads to a safety accident.

The installation work of the scaffold system becomes easy. Further, since the fastening portion of the guide rail is removed and the guide rail is fastened to the tip of the guide rail immediately before the start of work, separate welding is not necessary and further painting work is performed on the joint portion between the guide rail and the fastening portion. Is no longer necessary, leading to cost savings. Furthermore, since the plurality of fixing means for connecting the guide rail, the fastening portion, and the connecting portion are formed of a flexible material, storage is easy, and the convenience of the worker during use can be improved.

さらに、上部及び下部フランジの間に締結部が挿置されて連結部と締結部との接触及び支持が全体の面積に亘って行われ、外力または振動による揺れ及び離脱を生じることなく固定できることから、安全事故を未然に防ぐことができ、また、上部及び下部フランジが分岐状に足場支柱に取り付けられることから、ガイドレールの取付け後であっても、分岐状のフランジの結合手段を取り外して連結部を上下移動させることにより、ガイドレールの水平バランスを取ることができ、その結果作業が容易になり、しかも、時間を節減できる。 Furthermore, the fastening portion is inserted between the upper and lower flanges, and the contact and support between the connecting portion and the fastening portion are performed over the entire area, and can be fixed without causing shaking and detachment due to external force or vibration. Safety accidents can be prevented in advance, and the upper and lower flanges are attached to the scaffolding struts in a branched manner, so that even after the guide rail is installed, the connecting means of the branched flanges can be removed and connected By moving the part up and down, the guide rail can be balanced horizontally, and as a result, the work becomes easy and time can be saved.

加えて、足場支柱に取り付けられた連結部とガイドレールの締結部にそれぞれ形成される貫通孔と挿入孔を突き合わせ、上プレートの貫通孔と上面プレートの挿入孔による摩擦力によりテーパーキーを固定することから、従来に比べて前記テーパーキーの固定力が格段に強くなり、外力または振動が生じてもテーパーキーが離脱することなく、固定状態を保持することができる。また、連結部と締結部との接触面積が広くなり、外力または振動により左右回転が起きないように固定できることから、前記ガイドレールの安全度が高まって安全事故を予防することができる。 In addition, the through hole and the insertion hole formed in the connecting part attached to the scaffolding column and the fastening part of the guide rail are abutted, and the taper key is fixed by the frictional force generated by the through hole of the upper plate and the insertion hole of the upper plate. Therefore, the fixing force of the taper key is remarkably stronger than in the prior art, and the fixed state can be maintained without the taper key being detached even if an external force or vibration occurs. In addition, since the contact area between the connecting portion and the fastening portion is widened and can be fixed so as not to cause left-right rotation due to external force or vibration, the safety level of the guide rail is increased and a safety accident can be prevented.

図１２及び図１３を参照すると、連結部３２０は、前面と一方の面が開口される。また、前記連結部３２０の内側に形成された中空には締結部３５０が挿支される。また、前記締結部３５０は、ガイドレール３４０の両端にそれぞれ形成され、前記連結部３２０に挿入されて前記ガイドレール３４０を支持する。 Referring to FIGS. 12 and 13, the connection part 320 is open on the front surface and one surface. In addition, a fastening portion 350 is inserted and supported in the hollow formed inside the connecting portion 320. The fastening portions 350 are formed at both ends of the guide rail 340 and inserted into the connecting portion 320 to support the guide rail 340.

前記連結部３２０における上プレート３２１と下プレート３２２には、平面に貫通形成される貫通孔３２３がそれぞれ形成される。このとき、前記下プレート３２２の上面は、前記締結部３５０の下面と密接する。併せて、前記上プレート３２１の下面は、前記締結部３５０の上面と密接、あるいは近接するように配置されることが好ましい。また、前記連結部３２０の側面プレート３２４は、前記上プレート３２１と前記下プレート３２２のいずれかの一側面と連結される。これにより、前記側面プレート３２４の内側面は、前記締結部３５０の外側面と密接される。 The upper plate 321 and the lower plate 322 in the connecting part 320 are formed with through holes 323 penetrating in a plane. At this time, the upper surface of the lower plate 322 is in close contact with the lower surface of the fastening portion 350. In addition, the lower surface of the upper plate 321 is preferably disposed so as to be in close contact with or close to the upper surface of the fastening portion 350. In addition, the side plate 324 of the connection part 320 is connected to one side of either the upper plate 321 or the lower plate 322. Accordingly, the inner surface of the side plate 324 is brought into close contact with the outer surface of the fastening portion 350.

また、前記締結部３５０は、前面に垂直端面が形成され、前記垂直端面からそれぞれ折り曲げられて上面３５１と下面３５２を形成する。さらに、前記上面３５１と下面３５２にはそれぞれ挿入孔３５３が形成される。すなわち、前記締結部３５０は、前面と上面３５１、下面３５２は形成されるが、両側面が開口された四角形状に形成される。 In addition, the fastening portion 350 has a vertical end surface on the front surface, and is bent from the vertical end surface to form an upper surface 351 and a lower surface 352. Further, insertion holes 353 are formed in the upper surface 351 and the lower surface 352, respectively. That is, the fastening portion 350 is formed in a quadrangular shape in which a front surface, an upper surface 351, and a lower surface 352 are formed, but both side surfaces are opened.

そして、テーパーキー３６０は、一方の面が垂直端面を呈し、他方の端面が下方に進むにつれて狭幅となるように所定の傾斜角をもって形成される。このようにして形成された前記テーパーキー３６０は、前記貫通孔３２３及び挿入孔３５３に挿通され、これにより、前記連結部３２０と締結部３５０が固定される。 The taper key 360 is formed with a predetermined inclination angle such that one surface has a vertical end surface and the other end surface becomes narrower as it proceeds downward. The taper key 360 formed in this way is inserted through the through hole 323 and the insertion hole 353, whereby the connecting part 320 and the fastening part 350 are fixed.

以上のように構成された足場システムの組立て過程を説明すると、下記の通りである。 The assembly process of the scaffold system configured as described above will be described as follows.

一方、前記締結部３５０は、前記連結部３２０への挿通に際し、前記下プレート３２２により下方への移動が制限され、前記側面プレート３２４により一方の側方への移動が制限される。このため、前記締結部３５０の挿入に際し、前記下プレート３２２及び側面プレート３２４に密接すると、前記連結部３２０に形成された貫通孔３２３と前記締結部３５０に形成された挿入孔３５３が突き合わせられるように配置される。 Meanwhile, when the fastening portion 350 is inserted into the connecting portion 320, the lower plate 322 is restricted from moving downward, and the side plate 324 is restricted from moving to one side. For this reason, when the fastening portion 350 is inserted, when the lower plate 322 and the side plate 324 are in close contact, the through hole 323 formed in the connecting portion 320 and the insertion hole 353 formed in the fastening portion 350 are abutted. Placed in.

そして、このようにして貫通孔３２３及び挿入孔３５３が突き合わせられると、前記テーパーキー３６０を前記上プレート３２１の貫通孔３２３を通って前記締結部３５０の上面３５１と下面３５２にそれぞれ形成された挿入孔３５３を貫通し、前記下プレート３２２の貫通孔３２３を通って下側に突出される。 When the through hole 323 and the insertion hole 353 are brought into contact with each other in this way, the taper key 360 is inserted into the upper surface 351 and the lower surface 352 of the fastening portion 350 through the through hole 323 of the upper plate 321. It penetrates the hole 353 and protrudes downward through the through hole 323 of the lower plate 322.

これにより、前記連結部３２０と締結部３５０が固定され、その結果、前記足場支柱３１０にガイドレール３４０が固定される。 As a result, the connecting portion 320 and the fastening portion 350 are fixed, and as a result, the guide rail 340 is fixed to the scaffolding column 310.

すなわち、本発明は、前記連結部３２０の前面及び一方の面を開口し、前記締結部３５０を四角形状に形成して、前記締結部３５０を前記連結部３２０に嵌合しているため、前記連結部３２０と締結部３５０との接触面積が増大され、これにより、前記連結部３２０と締結部３５０との締付力が強くなる。 That is, the present invention opens the front surface and one surface of the connecting portion 320, forms the fastening portion 350 in a square shape, and fits the fastening portion 350 to the connecting portion 320. The contact area between the connection part 320 and the fastening part 350 is increased, and thereby the tightening force between the connection part 320 and the fastening part 350 is increased.

図１４は、本発明に係る足場システムの足場支柱連結装置の結合状態を示す斜視図であり、図１５(a)及び図１５(b)は、本発明に係る足場システムの足場支柱連結装置の結合関係を示す断面図及び斜視図である。 FIG. 14 is a perspective view showing a coupling state of the scaffolding column coupling device of the scaffold system according to the present invention, and FIGS. 15 (a) and 15 (b) are diagrams of the scaffolding column coupling device of the scaffolding system according to the present invention.

図１４及び図１５を参照すると、連結部４２０は、足場支柱４１０に固定されてガイドレール４４０を支持し、ガイドレール４４０は、前記足場支柱４１０に締め付けられて作業員の移動及び作業スペースをガイドする。また、前記連結部４２０において、上プレート４２１は、下部連結金具４２２の上面を覆うと共に、平面に貫通形成される貫通孔４２３を備える。そして、下部連結金具４２２は、四角形状またはその他の形状を有するように製作され、内側に中空が形成され、下面が開口される。 14 and 15, the connecting part 420 is fixed to the scaffolding column 410 to support the guide rail 440, and the guide rail 440 is fastened to the scaffolding column 410 to guide the movement of the worker and the working space. To do. In the connecting portion 420, the upper plate 421 includes a through hole 423 that covers the upper surface of the lower connecting fitting 422 and is formed through the plane. The lower connection fitting 422 is manufactured to have a quadrangular shape or other shapes, a hollow is formed inside, and a lower surface is opened.

また、前記締結部４５０は、前記ガイドレール４４０の両端にそれぞれ形成され、このうち下面プレート４５２は、前記下部連結金具４２２の下側に密着されて支持され、前記貫通孔４２３と突き合わせられる挿入孔４５３が形成される。また、上面プレート４５１は、前記連結部４２０の上プレート４２１の上面に密着あるいは近接することが好ましく、前記貫通孔４２３と突き合わせられる挿入孔４５３が形成される。さらに、前記上面プレート４５１と下面プレート４５２の一方の面には側面プレート４５４が形成される。 In addition, the fastening portions 450 are formed at both ends of the guide rail 440, respectively, and the lower surface plate 452 is supported in close contact with the lower side of the lower connection fitting 422 and is inserted into the through hole 423. 453 is formed. Further, the upper surface plate 451 is preferably in close contact with or close to the upper surface of the upper plate 421 of the connecting portion 420, and an insertion hole 453 that is abutted against the through hole 423 is formed. Further, a side plate 454 is formed on one surface of the upper plate 451 and the lower plate 452.

ここで、前記締結部４５０には、前記上面プレート４５１と下面プレート４５２、側面プレート４５４により囲まれた中空が形成され、この中空に前記連結部４２０が嵌合される。 Here, a hollow surrounded by the upper surface plate 451, the lower surface plate 452, and the side surface plate 454 is formed in the fastening portion 450, and the connecting portion 420 is fitted into the hollow.

そして、前記テーパーキー４６０は、一側が垂直端面を呈し、他側の端面は下方に進むにつれて側面が狭幅となるように所定の角度をもって形成され、前記上プレート４２１の貫通孔４２３と前記上面プレート４５１及び下面プレート４５２にそれぞれ形成される挿入孔４５３を挿通して前記締結部４５０を前記連結部４２０に固定する。 The taper key 460 is formed at a predetermined angle so that one side has a vertical end face and the other end face becomes narrower as it advances downward, and the through hole 423 of the upper plate 421 and the upper face are formed. The fastening portion 450 is fixed to the connecting portion 420 through insertion holes 453 formed in the plate 451 and the lower surface plate 452, respectively.

このようにして構成された足場システムの組立て過程を説明すると、下記の通りである。 The assembly process of the scaffold system configured as described above will be described as follows.

前記締結部４５０において、上面プレート４５１と、下面プレート４５２及び側面プレート４５４間の中空に前記連結部４２０が挿置される。 In the fastening portion 450, the connecting portion 420 is inserted into a space between the upper surface plate 451, the lower surface plate 452, and the side surface plate 454.

このとき、前記連結部４２０は、前記締結部４５０への嵌合に際し、前記下面プレート４５２により下方への移動が制限され、前記側面プレート４５４により側方への移動が制限される。これにより、前記連結部４２０が嵌合されて前記下面プレート４５２及び側面プレート４５４に密接されると、前記締結部４５０に形成された挿入孔４５３と前記連結部４２０に形成された貫通孔４２３が突き合わせられる。 At this time, when the connecting portion 420 is fitted to the fastening portion 450, the lower surface plate 452 restricts downward movement, and the side surface plate 454 restricts lateral movement. As a result, when the connecting part 420 is fitted and brought into close contact with the lower plate 452 and the side plate 454, the insertion hole 453 formed in the fastening part 450 and the through hole 423 formed in the connecting part 420 are formed. Matched.

このように、前記貫通孔４２３と挿入孔４５３が突き合わせられると、前記テーパーキー４６０を前記上面プレート４５１の挿入孔４５３に嵌合する。このとき、前記テーパーキー４６０は、前記上面プレート４５１の挿入孔４５３に嵌合された後、前記上プレート４２１と下部連結金具４２２の貫通孔４２３、前記下面プレート４５２の挿入孔４５３を順次に貫通して下側に突出される。 Thus, when the through hole 423 and the insertion hole 453 are abutted, the taper key 460 is fitted into the insertion hole 453 of the upper surface plate 451. At this time, after the taper key 460 is fitted into the insertion hole 453 of the upper surface plate 451, the upper plate 421, the through hole 423 of the lower connection fitting 422, and the insertion hole 453 of the lower surface plate 452 are sequentially penetrated. And protrudes downward.

これにより、前記テーパーキー４６０は、前記上面プレート４５１と下面プレート４５２の挿入孔４５３と前記上プレート４２１の貫通孔４２３の直径よりも大きな厚さを有する個所において挿入が止まり、このときに生じる摩擦力により前記締結部４５０と連結部４２０を固定する。 As a result, the taper key 460 stops being inserted at a location having a thickness larger than the diameters of the insertion holes 453 of the upper surface plate 451 and the lower surface plate 452 and the through holes 423 of the upper plate 421, and the friction generated at this time The fastening portion 450 and the connecting portion 420 are fixed by force.

すなわち、上面プレート４５１との摩擦力によりテーパーキー４６０を固定していた従来とは異なり、本発明においては、上プレート４２１を下部連結金具４２２の上面に固定させ、前記テーパーキー４６０と摩擦力を生じて固定可能な直径を有する貫通孔４２３を形成し、貫通孔と挿入孔による摩擦力を生じることから、従来に比べてテーパーキー４６０の固定力が強くなる。 That is, unlike the conventional case where the taper key 460 is fixed by the frictional force with the upper surface plate 451, in the present invention, the upper plate 421 is fixed to the upper surface of the lower connection fitting 422, and the taper key 460 and the frictional force are As a result, a through hole 423 having a fixable diameter is formed, and a frictional force is generated by the through hole and the insertion hole, so that the fixing force of the taper key 460 is stronger than the conventional one.
