Description

  The present invention relates to a connection structure for a suspension scaffold panel temporarily provided for repairing or inspecting a bridge girder such as a road.

  Generally, in repairing and inspecting bridge girders such as bridges and highways, there are many rivers and roadways underneath them, so it is impossible to assemble a temporary scaffold from the ground. For this reason, there are many temporary installations of suspension scaffolds suspended from bridge girders.

  Conventionally, a “single tube scaffolding method” is known as this type of suspended scaffolding. This is because the suspension chain is suspended from the bridge girder in the axial direction of the bridge girder (the direction of travel of the car) at a predetermined interval, the parent pipe is bridged between the suspension chains in the axial direction of the bridge girder, and between the parallel parent pipes. Rolling pipes in a direction perpendicular to the bridge girder's axis, spanning multiple pipes at a predetermined interval, and then placing a plurality of scaffolding plates on these rolling pipes in parallel with the axial direction of the bridge girder, and the lower and both sides of the scaffolding board Constructed by placing a safety net on the surface.

  However, suspension scaffolds using a single-tube scaffolding system must be installed while connecting individual parts such as single pipes, scaffolding plates, chains, etc., with connecting fittings such as clamps. Not only was it bothersome and cumbersome, it was dangerous.

  For this reason, the panel material formed by fixing and integrating the flooring material above the roughly rectangular frame is suspended in a chain suspended from the bridge part of the bridge girder and connected vertically and horizontally to increase the scaffolding area in the horizontal direction. An expanding “panel method” has been proposed and put into practical use.

  FIG. 1 is a schematic view of a suspension scaffold by a panel method. (a) is a cross-sectional view of the bridge girder in the direction perpendicular to the axis, and (b) is a plan view taken along the line AA.

  The suspension scaffold 1 suspends a chain 5 by a chain clamp 4 from a flange 3a of a bridge portion 3 made of I-shaped steel provided at an appropriate interval below a floor slab portion 2 of a bridge girder. A plurality of suspension chains 5 are installed in the axial direction of the bridge girder, or both in the axial direction of the bridge girder and in the direction perpendicular to the axis of the bridge girder. The long sides 6a and the short sides 6b are connected to each other by a connecting tool.

  In Patent Document 1, in order to connect the long sides of the panels, a connector that protrudes from the long side of the panel is provided on one side of the long side of the panel, and on the other side of the long side of the panel There has been proposed a panel provided with a connection receiving portion having a hole into which the tip of the protruding connection tool can be inserted.

  FIG. 2 is an example (conventional example) of a panel that is put into practical use based on Patent Document 1. (a) is a plan view, and (b) is a CC arrow view.

  FIG. 3 is a diagram showing an operation of connecting the two panels shown in FIG. 2 at their long sides.

  Here, the operator puts his knee on the first panel, and the long side portion 6a of the second panel to be connected to the tip of the connector 11 protruding from the side surface of the long side portion 6a of the panel. After the hole of the connection receiving portion 12 provided on the side surface of the connecting portion 12 is extrapolated, the through-hole 13 formed in the connection receiving portion 12 and the locking hole 14 formed in the connecting device 11 are aligned, After inserting the penetration pin 15 into the hole, the adjustment bolt 16 is tightened to complete the connection in the long side direction of the panels. Here, a floor material 8 is stretched on the upper surface of the panel, and an operator can work on it.

  Both short sides of the panel are formed by round pipes, and the short sides of the panels are connected to each other by engaging two round pipes with a normal fixing clamp.

Japanese Examined Patent Publication No. 7-103679

  However, when connecting and removing the long sides of the panel, it was found that this panel has the following problems (i) to (iii).

  (i) At the time of panel connection work, the knee position of the worker holding the panel material to be connected next (facing) must be inside the chain where the installed panel material is suspended. The reason for this is that if the operator's knee position is outside the chain, the entire panel material is tilted by the balance effect with the chain position as the axis of rotation, and the center of gravity of the operator's chain is suspended from the installed panel material. This is because there is a risk of losing balance because it comes outside. There is a similar problem when removing panels.

  FIG. 4 is an example showing a change in the center of gravity of the worker during the connection work at this time. When the worker's knee position 21a comes to the outside (left side) of the chain 5 that hangs the installed panel 6, it can be seen that the worker loses balance.

  (ii) Even when the operator's knee position is moved to the inside of the chain during the panel material connection work, when grasping the panel material to be connected (confronted) next, the length of half of the panel short side Because it is necessary to project the panel by the length (approx. 33 cm) + the length of the connector (approx. 10 cm) + the length (approx. 50 cm) plus a certain amount of clearance and the allowance of the handle (approx. 7 cm) Therefore, since the center of gravity of the worker moves to the outside of the chain, there is still a risk that the worker loses balance. There is a similar problem when removing panels.

  FIG. 5 is another example showing a change in the center of gravity of the worker during the connection work at this time. Even if the position of the worker's knee 21a is inside (right side) of the chain 5 that hangs the installed panel 6, the position of the center of gravity of the worker is outside of the chain 5 that suspends the installed panel 6 (left side). ), You can see that the workers lose their balance.

  (iii) The operator extrapolates the hole of the connection receiving portion provided on the side of the long side of the panel to be connected (facing) next to the tip of the connector protruding from the side of the long side of the installed panel. However, it is difficult to align the holes, and if the tip of the connector and the hole of the connection receiving portion are even slightly displaced, the connection cannot be established. Moreover, since the position of the hole of a connection receiving part is far from an operator, there exists a problem that it is difficult to aim.

  The present invention has been made to solve the above problems all at once, and an object of the present invention is to provide a suspended scaffold panel connection structure capable of connecting and removing the suspended scaffold panel safely and easily. .

  The inventors of the present invention have made extensive studies in order to make the connecting operation of the suspension scaffold panel safe and easy. As a result, the following findings (a) to (i) were obtained.

  (a) At the time of panel connection work, the center of gravity (knee) position of the worker who has the panel material to be connected (confronted) next must be inside the chain where the installed panel material is suspended. Although it is not, when grabbing the next panel to be connected (opposite), the length of the half of the short side of the panel + the length of the connector + a certain gap and a margin for the handle etc. The danger caused by protruding the panel can be reduced by shortening the protruding length.

  (b) As a measure to shorten the protruding length, it is conceivable to shorten the length of the panel short side. However, although the protruding length can be reduced, the number of panels to be installed increases, which increases man-hours (labor) and is difficult to employ.

  (c) However, even if the length of the short side of the next panel to be connected (facing) is not shortened, the gripping position of the panel to be next connected (faced) by the operator is changed from the panel short side to the panel length. I came up with the idea that if you change to the side and project the gripping position toward you, you can shorten the protruding length.

  For example, in the panel described in Patent Document 1, the hole of the connection receiving portion provided on the side of the long side of the panel to be connected next to the tip of the connector protruding from the side of the long side of the installed panel is removed. It is connected by inserting, but if the position of this connection tool and the connection receiving part is reversed, the tip of the connection tool that protrudes from the side of the long side of the panel that the operator connects next (facing) You can grab it. However, in this case, since the worker will further step out in order to put the position of the hole of the connection receiving portion provided on the side of the long side of the installed panel into view, the length of the protrusion of the worker Will not be shortened.

  FIG. 6 is a diagram illustrating a connection operation when the positions of the connection tool and the connection receiving portion 12 of the panel 6 shown in FIG. 2 are reversed. In this case, it can be seen that the worker goes further in order to put the position of the hole of the connection receiving portion 12 provided on the side surface of the long side portion of the installed panel 6 into view.

  (d) For this reason, as a result of further examination, a panel having connection receiving portions on both side surfaces of the panel long side portion is provided, and a deposit metal fitting protruding at a right angle from the panel long side portion is provided in one of the connection receiving portions. And it was conceived that a receiving metal fitting protruding at a right angle from the long side part of the panel may be provided in the other connection receiving part.

  Here, the connection receiving part provided in the both side surfaces of the panel long side part is formed in, for example, a tube shape, provided on each of the side surfaces of the panel long side part, and the deposit metal fitting and the receiving metal fitting are provided in each connection receiving part. However, a square tube or a circular tube shape connecting between the long side panel portions on both sides may be used, and deposit metal fittings and receiving metal fittings may be provided in both ends of the connection receiving portion. The number of connection receiving portions around the long side of each panel is not particularly limited, but is preferably two in view of safety and work efficiency.

  FIG. 7 shows a panel in which a metal fitting that protrudes from a long side of the panel at a right angle in one of the connection receiving portions and a metal fitting that protrudes from the long side of the panel at a right angle in the other connection receiving portion. It is a figure which shows a connection operation | work using.

  FIG. 8 is an example of a specific structure of the panel 6 including the deposit metal 25 and the receiving metal 26. (a) is a front view, (b) is an FF arrow view and GG arrow view of each, (c) is a state where a deposit metal is placed on a receiving metal, and (d) is The state which slid a deposit metal and was accommodated in the connection receiving part is shown.

  And the receiving metal fitting 26 has a cross-sectional shape formed from the bottom surface web and the flanges on both sides thereof, and the deposit metal fitting 25 has a cross-sectional shape formed from the top surface web and the flanges on both side surfaces thereof. Here, both the flanges of the deposit metal 25 are shaped so as to be placed inside the both flanges of the metal fitting 26, but may be shaped so as to be placed outside the both flanges of the metal fitting 26. In the case of this combination, even when one flange of the depositing metal 25 is placed between both flanges of the receiving metal 26, the depositing metal 25 can be combined with the receiving metal 26. Therefore, both the flanges of the deposit metal 25 do not necessarily have to be placed inside or outside of the both flanges of the receiving metal.

  In short, the shape of the metal fitting and the metal fitting can be received on the upper surface of the metal fitting and the metal fitting does not come off the upper surface of the metal fitting even if the metal fitting moves slightly in the direction of the side of the metal fitting. Any combination may be used.

  Therefore, as long as the metal fitting can be received on the upper surface of the metal fitting, and the metal fitting is a combination in a shape that does not come off the upper surface of the metal fitting even if the metal fitting moves slightly in the side direction of the metal fitting (A) The receiving metal fitting may have a cross-sectional shape (a U-shaped cross-sectional shape, a U-shaped cross-section, a semicircular cross-sectional shape, etc.) that is open upward or downward, formed from a bottom surface or a top web and flanges on both side surfaces. However, a closed cross-sectional shape may be obtained by covering the open portion.The web and the flange may be flat or curved, and may be formed from a tube or bar. Use a closed cross-sectional shape with a circular cross-section or a square cross-section (a closed cross-sectional shape may be obtained by covering the open part of the shaped steel), or (B) And a cross-sectional shape formed from the flanges on both sides thereof (a U-shaped cross-section, a U-shaped cross-section, a semicircular cross-sectional shape, etc., may be open downward or upward, but the open portion is covered) (The web and flange may be flat or curved.), Or a circular or angular cross section formed from a tube or bar. What is necessary is just to employ | adopt the obstruction | occlusion cross-sectional shape (It is good also as a obstruction | occlusion cross-sectional shape by covering the open part of a shaped steel.). In addition, when the deposit metal fitting or the receiving metal fitting has a closed cross-sectional shape, the rigidity becomes high, and there is an advantage that even if the deposit metal fitting or the metal fitting is hit against the ground or the like during transportation of the suspension scaffold panel, it is difficult to bend.

  For example, when adopting an upward open cross-sectional shape formed from a bottom web and flanges on both sides thereof as a metal fitting, a downward or upward open cross-sectional shape is adopted as a deposit metal, or a closed cross-sectional shape is adopted. Can do. Further, when adopting a downward open cross-sectional shape or a closed cross-sectional shape formed from the upper surface web and the flanges on both side faces as the metal fitting, a downward open cross-sectional shape can be adopted as the deposit metal.

  However, as shown in FIG. 8, the receiving metal has a cross-sectional shape formed from the bottom web and the flanges on both sides thereof, and the deposit metal has a cross-sectional shape formed from the top web and the flanges on both sides thereof. In order to prevent the deposit metal from being removed from the upper surface of the metal fitting, even if the metal fitting is moved slightly in the direction of the side of the metal fitting, the metal fitting can be received on the upper surface of the metal fitting. Needs to have a cross-sectional shape in which the entire metal fitting is incorporated into the receiving metal fitting, or a cross-sectional shape in which the entire metal fitting is incorporated into the metal fitting.

To summarize the above, the combinations of deposit metal fittings and metal fittings are as follows (i) to (vii).
(i) The metal fitting has a cross-sectional shape formed from a bottom web and flanges on both side surfaces thereof, and the deposit metal has a cross-sectional shape formed from a top surface web and flanges on both side surfaces thereof.
(ii) The metal fitting has a cross-sectional shape formed from a bottom web and flanges on both sides thereof, and the deposit metal can be placed inside the flanges of the metal fitting.
(iii) The receiving bracket has a cross-sectional shape formed from the bottom surface or upper surface web and the flanges on both sides thereof, and both flanges of the deposit metal having a cross-sectional shape formed from the upper surface web and the flanges on both side surfaces thereof. Those that can be placed on the outside of both flanges of the bracket.
(iv) The receiving metal fitting has a closed cross-sectional shape and can be placed inside both flanges of the deposit metal fitting having a cross-sectional shape formed from the upper surface web and the flanges on both side surfaces thereof.
(v) The depositor has a cross-sectional shape formed from the upper surface web and the flanges on both sides thereof, and can be mounted on the outside of the bracket by receiving both flanges of the depositor.
(vi) The metal fitting has a cross-sectional shape formed from the top or bottom web and the flanges on both sides thereof, and the metal fitting has a cross-sectional shape formed from the bottom or top web and the flanges on both sides thereof. One that can be placed inside both flanges of the bracket.
(vii) The deposit metal fitting has a closed cross-sectional shape and can be placed inside both flanges of a receiving metal fitting having a cross-sectional shape formed from a bottom web and flanges on both side surfaces thereof.

  In addition, in the case of the combination of the metal fittings and the metal fittings of (i) above, when the panel metal fittings are placed on the panel metal fittings facing each other, they are moved horizontally on the metal web of the metal fittings. If a notch is provided in a part of the flange on the same side of the receiving metal fitting and the deposit metal so that the mounting position in the cross-sectional direction of the deposit metal can be finely adjusted, it may be easy.

  (e) Then, after the deposit metal fitting is placed on the metal fitting, the deposit metal fitting may be slid on the metal fitting in the connection receiving portion provided in the side surface of the long side of the panel.

  In this way, instead of grasping the panel material itself to be connected (facing) next, the worker grasps a receiving metal fitting or a depositing metal metal protruding at a right angle from the long side portion of the panel to be connected (facing). Can be extended, the length of the protrusion from the panel is greatly reduced. Therefore, the risk of the operator being out of balance is greatly reduced. In addition, since both the metal fittings and the metal fittings protrude from the long side portion of the panel, the worker protrudes from the long side portion of the panel to be connected (facing) next. In either case, as long as it is a combination of a receiving metal fitting and a deposit metal fitting, it can be easily grasped.

  And, when the panels are connected, the tip of one of the metal fittings and the tip of the other metal fitting are close to each other, so that the positioning is easy. Moreover, since the other deposit metal fitting can be mounted on one receiving metal fitting, after placing, the deposit metal fitting can be moved horizontally on the metal fitting to finely adjust the deposit metal fitting position. That is, since the two-stage alignment operation of sliding the deposit metal fitting on the metal fitting and temporarily placing it on the metal fitting is possible, the connection operation can be performed easily and safely.

  (f) As described above, the shape of the metal fitting and the metal fitting can be received by the metal fitting on the upper surface of the metal fitting, and the metal fitting can be received even if the metal fitting is moved slightly in the lateral direction of the metal fitting. Any combination of shapes that does not deviate from the upper surface of the substrate may be used. As a result of further studies on this point, the upper surface of the metal fitting or the receiving metal fitting is not limited to the cross-sectional shape formed from the upper surface or the bottom web and the flanges on both sides thereof. The idea was that the same shape should be used so that the cross-sectional shape of the lower surface of the deposit metal matches. For example, if both have a V-shaped cross section opened upward, the deposit metal can be easily received on the upper surface of the metal fitting, and the deposit metal is received even if the deposit metal moves slightly in the lateral direction of the metal fitting. I thought that it was hard to come off from the upper surface of the bracket. Here, the cross-sectional V shape can be easily formed by using angle steel. Instead of the cross-sectional V shape, a cross-sectional U shape or a cross-sectional arc shape may be used.

  The deposit metal may use a V-shaped cross section opened upward as it is. However, if the open part with the V-shaped cross-section opened upward is covered with a cover with a triangular closed cross-section, the rigidity will be high, and even if the deposit metal is hit against the ground etc. Since it becomes difficult to bend, it is preferable to have a closed cross-sectional shape. In addition, the closed cross-sectional shape of the triangle may be a closed cross-sectional shape of the triangle by welding a flat plate to the open portion of the angle iron, or a triangular tube having a triangular cross-section may be used. Of course, it is preferable to have a closed cross-sectional shape when using a cross-sectional U shape or a circular arc shape.

  And as a metal fitting combined with a deposit metal with a V-shaped cross section, an upwardly open cross-sectional shape using angle steel may be used as it is. However, by adopting a closed cross-sectional shape as in the case of the deposit metal fitting, the rigidity can be increased, so that it is difficult to bend even if the receiving metal fitting is hit against the ground or the like during transportation of the suspended scaffolding panel. In order to make the V-shaped cross-section bracket into a closed cross-sectional shape, for example, by supporting a chevron steel having a V-shaped cross section from below with a steel material 27 having a U-shaped cross-section opened upward, the closed cross-sectional shape is changed. Can be formed. The angle-shaped steel having a V-shaped cross section and the steel material having a U-shaped cross section can be joined by fillet welding. Even when a U-shaped cross section or a circular arc shape is used as the deposit metal, it is preferable to have a closed cross-sectional shape.

  (g) If the guide material for the metal fitting is provided at a right angle to the long side of the panel on the upper surface of the long side of the panel at the protruding position of the metal fitting, just push the edge of the metal fitting with your limbs or a tool. Since the metal fitting is guided onto the metal fitting along the guide material provided on the upper surface of the long side of the panel facing the metal fitting, it can be easily placed on the metal fitting where the metal fitting is pre-positioned. can do. At this time, the protruding length of the worker is drastically reduced to about 15 cm, so that the risk of the operator being out of balance is greatly reduced. As the guide material, a method of fixing a member different from the panel, a method of using an end surface of a checker plate used as a floor surface of the panel, or the like can be considered. Further, the guide material may be installed either on the inside or outside of the flange of the deposit metal.

  FIG. 9 shows an example of a structure in which a guide member for a deposit metal is provided at a right angle to the long side of the panel on the upper surface of the long side of the panel at the protruding position of the receiving metal. (a) shows before and after placing the deposit metal fitting on the metal fitting. (b) is a HH arrow figure of (a), and illustrates three types of guide materials.

  When the deposit metal 25 is pushed to the left, it is guided and placed on the receiving metal 26 along the guide material 30 provided on the upper surface of the long-side member 35 of the long side of the facing panel. I understand.

  (h) After the deposit metal fitting is placed on the receiving metal fitting, as a means for connecting in the connection receiving portion facing the deposit metal fitting, a connecting bolt may be tightened in the connection hole drilled in the upper surface of the connection receiving member. . At this time, a screw portion for connecting the connecting bolt is required on the upper surface of the deposit metal, but it is sufficient that the fixing bolt can be inserted into the connecting hole formed in the upper surface of the connection receiving member and tightened. For this purpose, a threaded nut may be used, or the deposit metal may be directly cut using the thickness of the deposit metal.

  (i) The deposit metal is fixed to the upper surface in the connection receiving portion as described above. At this time, if it is fixed with a fixing bolt and the shape of the fixing hole formed in the upper surface of the connection receiving member is an oval, the installation of the suspension scaffold panel can be curved on a plane, Even if the bridge girder axis is curved left and right, it can be handled.

  FIG. 34 shows the situation when the deposit metal is temporarily placed and after setting, and is a view taken along the line R-R of the deposit metal and the receiving metal in FIG. (a) shows the temporary placement, and (b) shows the situation after setting.

  The deposit metal 25 fixed in the connection receiving portion 12 so as to protrude at right angles from the connection receiving portion 12 of the opposing panel is fixed in a shape protruding at right angles into the connection receiving portion 12 of the installed panel. After alignment with the receiving metal fitting 26, the deposit metal fitting 25 is temporarily placed on the receiving metal fitting 26. The deposit metal 25 has a circular cross section, and the receiving metal 26 has a semicircular cross section opened upward. Therefore, the deposit metal 25 temporarily placed on the receiving metal 26 is naturally a receiving metal. Fits on 26. Then, the deposit metal 25 is accommodated in the installed connection receiving part 12. Then, a connecting bolt (not shown) is inserted from the connecting hole 50 on the upper surface of the long-side member 35 of the suspension scaffold panel where the installed connection receiving portion 12 is located, and below the upper surface of the deposit metal 25. The panels can be temporarily connected to each other by screwing into the connecting nut 52 attached in contact therewith. Here, since it is in a temporarily connected state, there is a slight difference in the height of both panels, and as a result, there is a certain level of difference between the upper surfaces of the long-side members 35 of the two panels.

  As shown in FIGS. 29 to 34, after placing the deposit metal 25 on the receiving metal fitting 26, both panels can be connected by sliding the deposit metal 25. However, since they are in a temporarily connected state, there is a slight difference in the heights of both panels, and as a result, there is a certain level of difference between the upper surfaces of the long-side members 35 of the two panels. This step is caused by a gap (backlash) between the upper surface of the receiving bracket 25 and the upper surface of the connecting receiving portion 12 that is formed when the opposing receiving bracket 25 is accommodated in the installed connecting receiving portion 12. . Even in this state, the connection between the panels is completed, and there is no problem in strength. However, since there is a slight level difference between the panel long side members in the vicinity of the panel connecting portion, it is difficult to walk.

  In order to eliminate this level difference, the connecting bolt may be further tightened when the opposing metal fitting is connected to the upper surface of the already installed connection receiving portion by the connecting bolt. That is, when the connecting bolt is further tightened, the tip of the connecting bolt is grounded to the bottom surface of the receiving metal, and when further tightened, the upper surface of the deposit metal is grounded to the connecting receiving part, so that the step is eliminated.

  FIG. 35 is an example showing a procedure for eliminating a step between the panel long-side members after temporary connection. (a) is a state in which the deposit metal fitting 25 is accommodated in the connection receiving portion 12, (b) is a state in which the panels are temporarily connected with the connection bolt 51, and (c) is a bolt in which the connection bolt 51 is further tightened. (D) shows a state when the connection bolt 51 is further tightened and the upper surface of the deposit metal 25 is grounded to the upper surface of the connection receiving portion 12. .

  After housing the facing metal fitting 25 in the installed connection receiving portion 12, the connection bolt 51 extends from the connection hole 50 on the upper surface of the long side member of the suspension scaffold panel where the installed connection receiving portion 12 is located. And the panels can be temporarily connected to each other by screwing them into a connecting nut 52 attached in contact with the lower surface of the deposit metal 25. Since this is a temporarily connected state, there is a step between the panel long side members, but the connection between the panels is completed.

  However, as the connecting bolt 51 is tightened further, the tip of the connecting bolt 51 reaches the bottom surface of the receiving metal fitting 26 provided in the installed connecting receiving portion 12 and is grounded. The gap between the upper surfaces of the connection receiving parts 12 starts to decrease. Therefore, the step between the long side members also starts to decrease.

  When the connecting bolt 51 is further tightened, the upper surface of the installed connection receiving portion 12 is brought close to the upper surface of the metal fitting 25 via the connection nut 52, and finally the upper surface of the metal fitting 25 is moved. Since the upper surface of the connection receiving portion 12 is grounded, the step between the long side members is eliminated. Here, the connection of both panels is completed.

  Here, the connecting bolt 51 provided with a thread on only the head side of the bolt is used, but this is for reducing the number of times of screwing (labor). If there is no hassle, you can use the whole thread.

  Lastly, a fixing hole for passing a fixing bolt for fixing the metal fitting is drilled on the upper surface of the connection receiving part. By making the shape oval, the suspension scaffold panel is installed. It will be described in detail that can be curved on a plane.

  The installation location of the suspension scaffold panel is not limited to a straight line in a plan view. If a road or the like is curved, it may be necessary to curve the installation of the suspension scaffold panel on a plane.

  FIG. 36 is a diagram showing a situation when a plurality of suspension scaffold panels 6 are installed curvedly on a plane. (a) is a schematic view thereof, (b) is a plan view when attention is paid to two suspended scaffolding panels, (c) is an SS arrow view of (b), and (d) is (b) It is a TT arrow line view of).

  In FIG. 36 (b), the upper surface of the deposit metal provided protruding from the connection receiving portion of the lower panel 6 is fixed to the upper surface of the connection receiving portion of the upper panel 6 by fixing bolts 51. At this time, if the fixing hole 41 on the upper surface of the connection receiving portion is formed in an oval shape, a triangular gap 60 can be formed between the two panels. That is, when the fixing position of the fixing bolt 51 in the SS arrow view is left at the normal upper position, the fixing position of the fixing bolt 51 in the TT arrow view is changed to the lower position. A triangular gap 60 is formed between the two panels 6. By stacking the triangular gaps 60, the suspension scaffold panel can be curved.

  The suspension scaffold panel connection structure according to the present invention can shorten the protruding length of the worker and can easily align the panel with the facing panel. Therefore, it is possible to connect and remove the suspension scaffold panel safely and easily.
