Description

本発明は、種々のイベントその他の目的で床面を形成するために構築される仮設ステージに関する。 The present invention relates to a temporary stage constructed to form a floor surface for various events and other purposes.

公園や競技場等の屋外又は屋内において、種々のイベント等を開催する際、舞台その他の床面を形成するステージが構築されている。 When holding various events outdoors or indoors such as in a park or stadium, a stage or other stage that forms the floor is constructed.

このようなステージは、構築と解体が可能な仮設ステージとすることが好ましい。このため、従来、解体可能に構築された支持構造体に床パネルを縦横に敷設した仮設ステージが提案されている。 Such a stage is preferably a temporary stage that can be constructed and disassembled. For this reason, conventionally, a temporary stage in which floor panels are laid vertically and horizontally on a support structure constructed so as to be dismantled has been proposed.

前記支持構造体は、縦横方向に離間して支柱を立設すると共に、縦横方向に隣り合う支柱を梁装置により着脱自在に連結することにより構築されている。前記床パネルは、平面視を矩形に形成された側壁の長手方向に延びる底部を前記梁装置の軸方向に沿って搭載されている。 The support structure is constructed by erection of columns separated in the vertical and horizontal directions and detachably connecting columns adjacent to each other in the vertical and horizontal directions by a beam device. The floor panel has a bottom portion extending in the longitudinal direction of a side wall formed in a rectangular shape in a plan view along the axial direction of the beam device.

下記の特許文献１は、本出願人が提案した仮設ステージにおける梁装置を開示している。この梁装置は、該装置の両端部に支柱に着脱自在に固着される固着手段を設けると共に、上部に搭載部を形成した軸部材を備えており、前記軸部材の搭載部に床パネルの側壁底部を搭載するように構成している。 Patent Document 1 below discloses a beam device in a temporary stage proposed by the applicant. This beam device is provided with fixing means that are detachably fixed to columns at both ends of the device, and is provided with a shaft member having a mounting portion formed on the upper portion. The mounting portion of the shaft member is provided with a side wall of a floor panel. It is configured to mount the bottom.

特許第２９９９９５８号公報Japanese Patent No. 29999858

特許文献１により提案した従来の梁装置は、前記軸部材により、隣り合う支柱の間で軸方向に延びる搭載部を形成するので、床パネルの側壁底部を長手方向にわたり好適に支持することができる。 In the conventional beam device proposed in Patent Document 1, the shaft member forms a mounting portion extending in the axial direction between adjacent columns, so that the bottom side wall of the floor panel can be suitably supported in the longitudinal direction. ..

ところで、例えば、梁装置を支柱に着脱自在に固着する固着手段に関して、梁装置の顎部材を支柱のフランジに嵌合した状態で、該顎部材とフランジを貫通する楔孔に楔を打ち込むことにより緊結する楔式の緊結装置が構成されている場合、上方からハンマー等の工具で楔を打ち込むための開放空間が必要となる。因みに、楔式の緊結装置ではない別形式の固着手段が構成されている場合でも、梁装置の固着手段を支柱に固着する際、工具等を挿入するための開放空間が必要である。 By the way, for example, regarding the fixing means for detachably fixing the beam device to the support column, by driving a wedge into the wedge hole penetrating the jaw member and the flange in a state where the jaw member of the beam device is fitted to the flange of the support column. When a wedge-type binding device for binding is configured, an open space for driving the wedge with a tool such as a hammer from above is required. Incidentally, even when another type of fixing means other than the wedge type fastening device is configured, an open space for inserting a tool or the like is required when fixing the fixing means of the beam device to the support column.

このため、従来の梁装置においても、前記搭載部を形成する軸部材は、固着手段の上方位置まで延設されておらず、固着手段の上方空間を開放している。 Therefore, even in the conventional beam device, the shaft member forming the mounting portion is not extended to the position above the fixing means, and the space above the fixing means is opened.

しかしながら、縦横方向に隙間なく密に敷設された床パネルは、通常、隣り合う床パネルを支柱の上端の上方位置で接合させられており、従来の梁装置では、固着手段の上方に位置する床パネルの接合部を支持することができない。つまり、床パネルの側壁底部を全長にわたって搭載させ支持することができないという問題がある。 However, in floor panels laid densely in the vertical and horizontal directions without gaps, adjacent floor panels are usually joined at a position above the upper end of the column, and in a conventional beam device, the floor is located above the fixing means. Unable to support the joints of the panels. That is, there is a problem that the bottom of the side wall of the floor panel cannot be mounted and supported over the entire length.

本発明は、上記に鑑み、床パネルの側壁底部を支持する梁装置の搭載部に関して、該装置に固定された主搭載部と移動自在な補助搭載部により構成し、主搭載部と補助搭載部により床パネルの側壁底部を長手方向にわたり支持するように構成した梁装置を提供するものであり、上記楔式の緊結装置等の固着手段を支柱に固着する際は、該固着手段の上方空間を開放しているが、固着後に床パネルを搭載するときは、固着手段の上方位置においても床パネルの側壁底部を支持することができるようにした装置を構成することを課題としている。 In view of the above, in view of the above, the mounting portion of the beam device that supports the bottom of the side wall of the floor panel is composed of a main mounting portion fixed to the device and a movable auxiliary mounting portion, and the main mounting portion and the auxiliary mounting portion. The beam device is configured to support the bottom of the side wall of the floor panel in the longitudinal direction, and when the fixing means such as the wedge-type fastening device is fixed to the support column, the space above the fixing means is provided. Although it is open, when the floor panel is mounted after fixing, it is an object of the present invention to configure a device capable of supporting the bottom of the side wall of the floor panel even at an upper position of the fixing means.

そこで、本発明が手段として構成したところは、支持構造体に床パネルを縦横に敷設して成る仮設ステージに関して、前記支持構造体は、縦横方向に離間して立設した支柱のうち縦横方向に隣り合う支柱を梁装置により着脱自在に連結することにより構築されており、前記床パネルは、平面視を矩形に形成された側壁の底部を前記梁装置の軸方向に沿って搭載される構成において、前記梁装置は、両端部に前記支柱に着脱自在な固着手段を設けた梁軸部材と、該梁軸部材の上部に固設された支持軸部材と、該支持軸部材の両端部に位置して軸方向に移動自在な補助支持部材を備えており、前記支持軸部材の上部に形成された主搭載部と前記補助支持部材の上部に形成された補助搭載部により床パネルの側壁底部を支持するように構成すると共に、前記補助支持部材の移動を介して、前記補助搭載部を固着手段の上方空間に干渉しない位置から該固着手段の上方位置に移動させるように構成して成る点にある。 Therefore, what the present invention has constructed as a means is that with respect to a temporary stage in which floor panels are laid vertically and horizontally on the support structure, the support structure is arranged in the vertical and horizontal directions among the columns erected apart from each other in the vertical and horizontal directions. It is constructed by detachably connecting adjacent columns with a beam device, and the floor panel is configured such that the bottom of a side wall formed in a rectangular shape in a plan view is mounted along the axial direction of the beam device. The beam device is located at both ends of a beam shaft member provided with detachable fixing means to the support column at both ends, a support shaft member fixed to the upper portion of the beam shaft member, and both ends of the support shaft member. An auxiliary support member that is movable in the axial direction is provided, and the side wall bottom portion of the floor panel is formed by the main mounting portion formed on the upper portion of the support shaft member and the auxiliary mounting portion formed on the upper portion of the auxiliary support member. In addition to being configured to support, the auxiliary mounting portion is configured to be moved from a position that does not interfere with the space above the fixing means to an upper position of the fixing means through the movement of the auxiliary supporting member. is there.

本発明の好ましい実施形態において、前記補助支持部材は、前記支持軸部材の端部に伸縮自在に嵌入された伸縮管を構成し、前記支持軸部材の外側に位置する伸縮管の外側端部の上部に座部材を設けており、前記座部材により前記補助搭載部を形成している。 In a preferred embodiment of the present invention, the auxiliary support member constitutes a telescopic tube that is stretchably fitted into an end portion of the support shaft member, and is an outer end portion of the telescopic tube located outside the support shaft member. A seat member is provided on the upper portion, and the auxiliary mounting portion is formed by the seat member.

好ましくは、前記補助支持部材を構成する伸縮管に伸縮ロック装置を設けており、前記伸縮ロック装置は、伸縮管の側壁から出没自在かつ突出方向に付勢された係止片と、該係止片を挿通させるように前記支持軸部材の軸方向に間隔をあけて形成された複数の係止孔により構成されている。 Preferably, the telescopic lock device is provided on the telescopic tube constituting the auxiliary support member, and the telescopic lock device includes a locking piece that is bulging from the side wall of the telescopic tube and is urged in the protruding direction, and the locking. It is composed of a plurality of locking holes formed at intervals in the axial direction of the support shaft member so as to allow one piece to pass through.

本発明によれば、梁装置４は、補助支持部材１２を移動することにより補助搭載部１３ｂを固着手段１０の上方空間に干渉しないように位置させることにより、固着手段１０を支柱３に固着する作業を行い、このようにして梁軸部材７により支柱３、３を連結した後は、必要に応じて、補助支持部材１２を移動することにより補助搭載部１３ｂを所望の位置に定置させることにより、支持軸部材８に搭載される床パネル２の側壁底部を長手方向にわたり主搭載部１３ａと補助搭載部１３ｂの両者により好適に支持することができるという効果がある。 According to the present invention, the beam device 4 fixes the fixing means 10 to the support column 3 by moving the auxiliary support member 12 so as to position the auxiliary mounting portion 13b so as not to interfere with the space above the fixing means 10. After performing the work and connecting the columns 3 and 3 by the beam shaft member 7 in this way, the auxiliary mounting portion 13b is placed at a desired position by moving the auxiliary support member 12 as necessary. There is an effect that the bottom side wall portion of the floor panel 2 mounted on the support shaft member 8 can be suitably supported by both the main mounting portion 13a and the auxiliary mounting portion 13b in the longitudinal direction.

図３及び図４に示すように、前記補助支持部材１２は、支持軸部材８の端部に伸縮自在に嵌入された金属製の角パイプから成る伸縮管１５を構成し、支持軸部材８の端部よりも外側に位置する伸縮管１５の外側端部の上部に座部材１６を設け、該座部材１６により前記補助搭載部１２を形成している。図示実施形態の場合、前記伸縮管１５の外側端部の上面と両側面に門形の金属板から成る座部材１６を被冠すると共に溶接等で固着することにより、該座部材１６の上面により補助搭載部１３ｂを形成している。 As shown in FIGS. 3 and 4, the auxiliary support member 12 constitutes an expansion / contraction tube 15 made of a metal square pipe that is stretchably fitted at the end of the support shaft member 8. A seat member 16 is provided above the outer end portion of the telescopic tube 15 located outside the end portion, and the auxiliary mounting portion 12 is formed by the seat member 16. In the case of the illustrated embodiment, the seat member 16 made of a gate-shaped metal plate is crowned on the upper surface and both side surfaces of the outer end portion of the telescopic tube 15 and fixed by welding or the like to the upper surface of the seat member 16. The auxiliary mounting portion 13b is formed.

このような座部材１６を設けることにより、補助搭載部１３ｂの高さ位置が主搭載部１３ａとほぼ面一となるように形成され、床パネル２の側壁６の底部を長手方向にわたり同じ高さ位置で支持することができる。しかも、図３に示すように、伸縮管１５を支持軸部材８に最も収縮させたとき、前記座部材１６が支持軸部材８の端面に当接するストッパ１７を形成する。 By providing such a seat member 16, the height position of the auxiliary mounting portion 13b is formed so as to be substantially flush with the main mounting portion 13a, and the bottom portion of the side wall 6 of the floor panel 2 is formed to have the same height in the longitudinal direction. Can be supported in position. Moreover, as shown in FIG. 3, when the telescopic tube 15 is most contracted to the support shaft member 8, the seat member 16 forms a stopper 17 that comes into contact with the end surface of the support shaft member 8.

前記補助支持部材１２を構成する伸縮管１５は、伸縮ロック装置１８を設けており、図３に示すように伸縮管１５を収縮させた位置に移動したときや、図４に示すように伸縮管１５を伸長させた位置に移動したとき、伸縮移動を不能とするようにロックする。 The telescopic tube 15 constituting the auxiliary support member 12 is provided with a telescopic lock device 18, and when the telescopic tube 15 is moved to a contracted position as shown in FIG. 3, or as shown in FIG. 4, the telescopic tube 15 is stretched. When the 15 is moved to the extended position, it is locked so that the expansion / contraction movement is disabled.

前記伸縮ロック装置１８は、伸縮管１５の両側壁から出没自在かつ突出方向に付勢された係止片１９と、該係止片１９を挿通させるように支持軸部材８の両側壁に軸方向に間隔をあけて形成された複数の係止孔２０により構成されており、図例の場合、軸方向に間隔をあけて配置された第１係止孔２０ａと、第２係止孔２０ｂと、第３係止孔２０ｃが配置されている。 The telescopic lock device 18 has a locking piece 19 that can freely appear and disappear from both side walls of the telescopic tube 15 and is urged in a protruding direction, and an axial direction through both side walls of the support shaft member 8 so as to insert the locking piece 19. In the case of the figure, the first locking holes 20a and the second locking holes 20b are arranged at intervals in the axial direction. , The third locking hole 20c is arranged.

図示実施形態の場合、伸縮管１５の内部に装入したＵ字形ないしコ字形の板バネから成るスプリング２１の両端部に外向きのピンを設けると共に、該ピンを伸縮管１５の両側壁から挿通孔を介して突出させることにより係止片１９、１９を構成し、該係止片１９、１９を支持軸部材８の両側壁に対向して開設された係止孔２０、２０に挿通させている。従って、作業者が一対の指先等により両係止片１９、１９を摘まんで挟持することにより係止孔２０、２０から支持軸部材８の内部に没入させると、伸縮管１５を伸縮させることができ、伸縮移動により係止片１９、１９が何れかの係止孔２０、２０に臨むと、スプリング２１により係止片１９、１９が自動的に係止孔２０、２０に挿通されて係止し、伸縮移動不能とするようにロックする。 In the case of the illustrated embodiment, outward pins are provided at both ends of a spring 21 made of a U-shaped or U-shaped leaf spring charged inside the telescopic tube 15, and the pins are inserted from both side walls of the telescopic tube 15. The locking pieces 19 and 19 are formed by projecting through the holes, and the locking pieces 19 and 19 are inserted into the locking holes 20 and 20 formed so as to face the side walls of the support shaft member 8. There is. Therefore, when the operator picks and holds both the locking pieces 19 and 19 with a pair of fingertips or the like to immerse the locking pieces 20 and 20 into the inside of the support shaft member 8, the telescopic tube 15 can be expanded and contracted. When the locking pieces 19 and 19 face any of the locking holes 20 and 20 due to the expansion and contraction movement, the locking pieces 19 and 19 are automatically inserted into the locking holes 20 and 20 by the spring 21 and locked. And lock it so that it cannot be expanded or contracted.

係止孔２０の個数や間隔は、目的に応じて設計変更可能であるが、図示実施形態の場合、後述する目的により、係止片１９を第１係止孔２０ａに挿入係止したとき伸縮管１５が収縮位置に移動された状態で補助支持部材１２の補助搭載部１３ｂを第１位置Ｐ１に停止し、係止片１９を第２係止孔２０ｂに挿入係止したとき伸縮管１５が中間伸長位置に移動された状態で補助支持部材１２の補助搭載部１３ｂを第２位置Ｐ２に停止し、係止片１９を第３係止孔２０ｃに挿入係止したとき伸縮管１５が最大伸長位置に移動された状態で補助支持部材１２の補助搭載部１３ｂを第３位置Ｐ３に停止するように、３段階による伸縮位置が可能となるように構成されている。 The number and spacing of the locking holes 20 can be changed in design according to the purpose, but in the case of the illustrated embodiment, when the locking piece 19 is inserted into the first locking hole 20a and locked, it expands and contracts for the purpose described later. When the auxiliary mounting portion 13b of the auxiliary support member 12 is stopped at the first position P1 and the locking piece 19 is inserted and locked in the second locking hole 20b while the pipe 15 is moved to the contracted position, the telescopic pipe 15 is inserted. When the auxiliary mounting portion 13b of the auxiliary support member 12 is stopped at the second position P2 in the state of being moved to the intermediate extension position and the locking piece 19 is inserted and locked in the third locking hole 20c, the expansion tube 15 is maximally extended. It is configured so that the auxiliary mounting portion 13b of the auxiliary support member 12 can be extended and contracted in three stages so as to stop at the third position P3 while being moved to the position.

（梁装置の取付固着）
梁装置４は、伸縮ロック装置１８の係止片１９を第１係止孔２０ａに挿通係止させ、伸縮管１５を完全に収縮させることにより、補助支持部材１２の補助搭載部１３ｂを固着手段１０の上方空間に干渉しない第１位置Ｐ１に停止した状態で、梁軸部材７の固着手段１０を支柱３に固着される。 (Attachment and fixation of beam device)
The beam device 4 inserts and locks the locking piece 19 of the telescopic lock device 18 into the first locking hole 20a, and completely contracts the telescopic tube 15, thereby fixing the auxiliary mounting portion 13b of the auxiliary support member 12. The fixing means 10 of the beam shaft member 7 is fixed to the support column 3 in a state of being stopped at the first position P1 that does not interfere with the space above the 10.

補助搭載部１３ｂを第１位置Ｐ１に停止させることにより、固着手段１０の上方空間が開放されているので、工具等を使用することにより、該固着手段１０を支柱３に固着することができる。 Since the space above the fixing means 10 is opened by stopping the auxiliary mounting portion 13b at the first position P1, the fixing means 10 can be fixed to the support column 3 by using a tool or the like.

（梁装置の第１使用例）
図５は、梁装置４の第１使用例を示しており、支持軸部材８に搭載される床パネル２の側壁６は、底部を長手方向にわたり主搭載部１３ａに支持されると共に、底部の長手方向端部６ａを支柱３の上端部の上方に位置させる場合を示している。従来技術に関して上述したように、縦横方向に隙間なく密に敷設される床パネル２は、通常、隣り合う床パネル２、２を支柱３の上端の上方位置で接合させられるので、側壁底部の長手方向端部６ａが支柱３の直上に位置することになる。 (First use example of beam device)
FIG. 5 shows a first use example of the beam device 4, in which the side wall 6 of the floor panel 2 mounted on the support shaft member 8 is supported by the main mounting portion 13a in the longitudinal direction at the bottom and at the bottom. The case where the end portion 6a in the longitudinal direction is positioned above the upper end portion of the support column 3 is shown. As described above with respect to the prior art, in the floor panel 2 laid densely in the vertical and horizontal directions without gaps, the adjacent floor panels 2 and 2 are usually joined at a position above the upper end of the column 3, so that the length of the bottom of the side wall is long. The directional end 6a is located directly above the support column 3.

そこで、第１使用例の場合、梁装置４は、上述のように補助支持部材１２を収縮させた状態で、梁軸部材７の固着手段１０を支柱３に固着した後、図５に示すように、伸縮管１５を最大伸長位置まで伸長させると共に係止片１９を第３係止孔２０ｃに挿通係止することによりロックし、補助搭載部１３ｂを固着手段１０の上方空間が含まれる支柱３の上方位置とされた第３位置Ｐ３に位置させられる。 Therefore, in the case of the first use example, in the beam device 4 in the state where the auxiliary support member 12 is contracted as described above, the fixing means 10 of the beam shaft member 7 is fixed to the support column 3, and then as shown in FIG. The telescopic tube 15 is extended to the maximum extension position, and the locking piece 19 is inserted into and locked in the third locking hole 20c to lock the expansion tube 15, and the auxiliary mounting portion 13b is locked by the support column 3 including the space above the fixing means 10. It is located at the third position P3, which is the position above.

従って、この状態で床パネル２を梁装置４に搭載すると、床パネル２の側壁底部は、長手方向にわたり支持軸部材８の主搭載部１３ａにより支持されると共に、長手方向端部６ａを補助支持部材１２の補助搭載部１３ｂにより支持される。従って、主搭載部１３ａと補助搭載部１３ｂにより床パネル２の側壁底部を長手方向の全長にわたり好適に支持することができる。 Therefore, when the floor panel 2 is mounted on the beam device 4 in this state, the side wall bottom portion of the floor panel 2 is supported by the main mounting portion 13a of the support shaft member 8 in the longitudinal direction, and the end portion 6a in the longitudinal direction is assisted. It is supported by the auxiliary mounting portion 13b of the member 12. Therefore, the main mounting portion 13a and the auxiliary mounting portion 13b can suitably support the bottom side wall portion of the floor panel 2 over the entire length in the longitudinal direction.

（梁装置の第２使用例）
図６は、梁装置４の第２使用例を示しており、支柱３の上部には継手２２を介して延長支柱３ａが立設される。この場合、床パネル２の側壁６は、延長支柱３ａに臨む隅部に面取り壁６ｂが形成され、延長支柱３ａに干渉しないように構成されており、図示のように、側壁６の底部の長手方向端部６ａは、延長支柱３ａまで達しない。 (Second use example of beam device)
FIG. 6 shows a second usage example of the beam device 4, in which an extension column 3a is erected on the upper portion of the column 3 via a joint 22. In this case, the side wall 6 of the floor panel 2 has a chamfered wall 6b formed at a corner facing the extension column 3a so as not to interfere with the extension column 3a, and is configured so as not to interfere with the extension column 3a. The directional end 6a does not reach the extension column 3a.

そこで、第２使用例の場合、梁装置４は、上述のように補助支持部材１２を収縮させた状態で、梁軸部材７の固着手段１０を支柱３に固着した後、図６に示すように、伸縮管１５を中間伸長位置まで伸長させると共に係止片１９を第２係止孔２０ｂに挿通係止することによりロックし、補助搭載部１３ｂを固着手段１０の上方空間となる第２位置Ｐ２に位置させられる。 Therefore, in the case of the second use example, in the beam device 4 in the state where the auxiliary support member 12 is contracted as described above, the fixing means 10 of the beam shaft member 7 is fixed to the support column 3, and then as shown in FIG. In addition, the expansion tube 15 is extended to the intermediate extension position and the locking piece 19 is inserted and locked in the second locking hole 20b to lock the expansion tube 15, and the auxiliary mounting portion 13b is the second position which becomes the space above the fixing means 10. It is located at P2.

従って、この状態で床パネル２を梁装置４に搭載すると、床パネル２の側壁底部は、長手方向にわたり支持軸部材８の主搭載部１３ａにより支持されると共に、面取り壁６ｂの近傍で長手方向端部６ａを補助支持部材１２の補助搭載部１３ｂにより支持される。 Therefore, when the floor panel 2 is mounted on the beam device 4 in this state, the side wall bottom portion of the floor panel 2 is supported by the main mounting portion 13a of the support shaft member 8 in the longitudinal direction, and is supported in the longitudinal direction in the vicinity of the chamfered wall 6b. The end portion 6a is supported by the auxiliary mounting portion 13b of the auxiliary support member 12.

（梁装置の第３使用例）
図７は、梁装置４の第３使用例を示しており、支柱３の上部にはテーブル状の支持具２３が装着される。この場合、床パネル２は、縦横方向に隙間なく密に敷設され、隣り合う床パネル２、２の隅部を接合した状態で支持具２３の上に支持されると共に、該支持具２３に立設した挟持片２３ａにより、隅部の側壁６を接合状態で挟持される。従って、床パネル２の隅部に位置する側壁底部の長手方向端部６ａは、支持具２３により支持される。 (Third use example of beam device)
FIG. 7 shows a third use example of the beam device 4, in which a table-shaped support 23 is mounted on the upper portion of the support column 3. In this case, the floor panel 2 is densely laid in the vertical and horizontal directions without gaps, and is supported on the support 23 with the corners of the adjacent floor panels 2 and 2 joined, and stands on the support 23. The side wall 6 at the corner is sandwiched by the provided sandwiching piece 23a in a joined state. Therefore, the longitudinal end portion 6a of the side wall bottom portion located at the corner of the floor panel 2 is supported by the support tool 23.

そこで、第３使用例の場合、梁装置４は、上述のように補助支持部材１２を収縮させた状態で、梁軸部材７の固着手段１０を支柱３に固着した後、そのままの状態、即ち、伸縮管１５を収縮させ、係止片１９を第１係止孔２０ａに挿通係止することによりロックし、補助搭載部１３ｂを第１位置Ｐ１に位置させたままの状態で使用される。つまり、補助搭載部１３ｂは、支持具２３に干渉しない位置に停止させられた状態で使用される。 Therefore, in the case of the third use example, the beam device 4 has the auxiliary support member 12 contracted as described above, and after the fixing means 10 of the beam shaft member 7 is fixed to the support column 3, that is, the state as it is. The telescopic tube 15 is contracted, the locking piece 19 is inserted and locked in the first locking hole 20a, and the auxiliary mounting portion 13b is used in the state of being positioned at the first position P1. That is, the auxiliary mounting portion 13b is used in a state of being stopped at a position where it does not interfere with the support tool 23.

従って、この状態から、床パネル２を梁装置４に搭載すると、床パネル２の側壁底部は、長手方向にわたり支持軸部材８の主搭載部１３ａと補助支持部材１２の補助搭載部１３ｂにより支持され、長手方向端部６ａは、支持具２３により支持される。 Therefore, when the floor panel 2 is mounted on the beam device 4 from this state, the side wall bottom portion of the floor panel 2 is supported by the main mounting portion 13a of the support shaft member 8 and the auxiliary mounting portion 13b of the auxiliary support member 12 in the longitudinal direction. , The longitudinal end 6a is supported by the support 23.
