Bolts are passed so as to penetrate, and are fastened and fixed by bolts and nuts from both outer sides of the attachment pipe 31b. In addition, in the case of the 2nd clamping part 3b, such fixation is performed in any one of the two attachment holes 311b. At this time, any one of the three mounting holes 22 of the horizontal member 2 is selected and fixed. Depending on how the attachment holes 311b and the attachment holes 22 are selected, the attachment positions of the second clamping portion 3b in the longitudinal direction of the horizontal member 2 can be changed in six ways.

  The arm member 32b is made of H steel.

  As an example, the attachment tube 41 is formed of a tube member of STKM (carbon steel tube for mechanical structure) 13A 60.5 mmφ (outer diameter) × 5 mm (thickness), and has a longitudinal dimension of 120 mm. In addition, the attachment tube 41 is provided with two attachment holes 411 (as an example, the dimension is 11.5 mmφ (diameter)) for attachment to the horizontal member 2. Each of these mounting holes 411 is formed as a pair of holes at the same position on the side visible in FIG. 2D and the opposite side.

  At the time of mounting, the mounting pipe 41 and the horizontal member 2 are fitted (the horizontal member 2 is inserted into the mounting pipe 41), the positions of the mounting hole 23 and the mounting hole 411 are aligned at the positions shown in FIG. Bolts are passed through them, and tightened from both outsides of the mounting tube 41 with bolts and nuts and fixed. In addition, in the case of the suspended coupling part 4, such fixing is performed in any one of the two attachment holes 411. At this time, any one of the two attachment holes 23 of the horizontal member 2 provided for each of the suspended coupling portions 4A and 4 is selected and fixed. Depending on how the attachment holes 411 and the attachment holes 23 are selected, the attachment positions in the longitudinal direction of the horizontal member 2 of the suspended coupling portion 4 can be changed in three ways. In the example shown in FIGS. 1 and 2, the distance between the two attachment holes 23 and the distance between the two attachment holes 411 with respect to one suspended coupling portion 4 have the same dimensions.

  The attachment member 42 and the coupling member 43 are constituted by a tube member and a plate member, respectively.

  The structure on the suspended object side includes a coupling member 44 and a rail case 45. The coupling member 44 is fixed to the coupling member 43 with bolts and nuts. The coupling member 44 is configured by a plate member.

  The rail case 45 is a case for inserting a rail 201 for horizontally moving the suspended object, and is fixed to the coupling member 44. As shown in FIG. 2E, the rail case 45 is a rectangular tube having a rectangular hollow cross section with an open bottom, and its length is 250 mm as an example. Moreover, although not shown in figure, the rail case 45 is provided with the some attachment hole for fixing the rail 201 to the length direction side surface. The rail case 45 is made of a plate-shaped steel material.

  FIG. 1 shows a state in which a suspension mechanism 200 including a rail 201 is inserted into the rail case 45. The suspension mechanism 200 includes a rail 201, a single vehicle 202, and a hook 203. The rail 201 is laid for a predetermined length in the thickness direction of the paper surface of FIG. 1, and the single vehicle 202 and the hook 203 are horizontally movable along the rail 201. A desired suspended object is suspended from the hook 203. In addition, the hook 203 can be comprised with an eye nut.

  As suspended items, a fall prevention device 500 (safety rope (wire rope 501 etc.) of the worker who assembles the temporary scaffold 900, a fall prevention device 600 (net 601) to the outside such as the sidewalk side when the temporary scaffold 900 is assembled. Etc.) and a winch for unloading.

  Next, when using the support tool 1 as a tool for supporting the temporary scaffolding 900, the work floor coupling unit 5 is a worker when assembling the temporary scaffolding 900 of the lowermost layer (usually the second floor level or more of the building). It is a part for attaching the work floor used. As shown in FIG. 1 and FIG. 2C, the work floor coupling portion 5 is fixedly attached to the arm member 32b of the second sandwiching portion 3b. As an example, STK (general structural carbon steel pipe) It is composed of a tubular member of 500 48.6 mmφ (outer diameter) × 2.4 mm (thickness).

  As shown in FIG. 2C, the work floor coupling portion 5 is provided with a mounting hole 51 (for example, a dimension of 11.5 mmφ (diameter)). When attaching the work floor, a tubular frame member (support member 301) of the work floor is inserted into the work floor coupling portion 5, and bolts and attachment holes 51 are provided using the attachment holes and the attachment holes 51 provided in the frame member. Fix both with nuts. In addition, the support member 301 is comprised by the tubular member of 42.7 mmphi (outer diameter) x 1,000 mm (length) as an example. Further, a pin may be used for fixing the work floor coupling portion 5 and the support member 301, and the pin may be passed through the mounting hole.

  In addition, the tubular member used as the horizontal member 2 and the work floor coupling | bond part 5 is a member which has the diameter of the dimension matched with the tubular member used with the temporary scaffold 900 like the example mentioned above. Specifically, conventionally, as an example, the temporary scaffold itself has been a member having a diameter of 42.7 mmφ, and a member having a diameter of 48.6 mmφ has been used as a member to reinforce them. The floor joint 5 has the same diameter as the latter. As a result, when assembling the temporary scaffold 900, conventional joining parts and joining parts can be used as they are, and there is no need to manufacture new tools and parts.

  Next, the anti-slip member 6 is attached to the tip of the horizontal member 2 (the end opposite to the sandwiching portion 3) and prevents the suspended coupling portion 4 and the like from slipping out (sliding out) from the horizontal member 2. It is. As an example, the anti-slip member 6 is formed of a tube member of STKM (carbon steel pipe for machine structure) 13A 60.5 mmφ (outer diameter) × 5 mm (thickness), and has a longitudinal dimension of 25 mm. Further, the anti-slip member 6 is provided with an attachment hole 61 (as an example, the dimension is 11.5 mmφ (diameter)) for attachment to the horizontal member 2. These attachment holes 61 are formed as a pair of holes at the same position on the side visible in FIG. 2F and the opposite side.

  At the time of attachment, the anti-slip member 6 and the horizontal member 2 are fitted (the horizontal member 2 is inserted into the anti-slip member 6), the positions of the attachment hole 24 and the attachment hole 61 are aligned at the positions shown in FIG. Bolts are passed through the holes and fastened with bolts and nuts from both outer sides of the anti-slip member 6 to be fixed.

[Example of application when supporting temporary scaffold 900]
Next, an application example when the support tool 1 is used as a tool (structure) that supports the temporary scaffold 900 will be described. FIG. 3 is a diagram showing an example in which the temporary scaffold 900 is assembled on the support tool 1 as a support structure. In such an application example, the support 1 is attached to the outer wall (building wall 100) of a building such as an apartment at a predetermined interval P (for example, an interval of 1,800 mm) in a direction along the building wall 100 (X direction in FIG. 3). It attaches with the clamping part 3 in the direction (Y direction of FIG. 3) which protrudes outside a building.

  Thereafter, the frame member, floor member, and the like of the temporary scaffold 900 are sequentially assembled on the plurality of attached support tools 1 (horizontal members 2).

  In FIG. 3, only the range of the two support tools 1 is shown, and the temporary scaffold 900 can be similarly assembled in the direction of the arrow X1 and the direction of the arrow X2 in FIG. 3 shows a work floor 300 provided under the support 1 (below the Z direction in FIG. 3), and a reinforcing member 7 fixed to the tip of the support 1, which will be described later. To do.

  FIG. 4 is a diagram showing an application example in which a work floor 300 for workers who assemble the temporary scaffold 900 is attached. FIG. 4 shows an application example for the range of the two supports 1.

  In the assembly work of the temporary scaffold 900 described above, the work is performed from the lowest level (floor), but in the lowest layer (below in the Z direction in FIG. 4), when the support 1 is attached to the building wall 100. There is still no scaffolding, and there is no effective space where workers can stay and work. Therefore, first, the work floor 300 shown in FIG. 4 is made using the attached support 1.

  At that time, the support member 301 of the work floor 300 is attached and fixed to the work floor coupling portion 5 of each support 1 described above, and both the supports that are attached and project outside the building (in the Y direction in FIG. 4). The work floor 300 is completed by passing the floor plate 302 between the members 301.

  Thereby, an effective space for assembling the temporary scaffold 900 in the lowermost layer is secured. Further, the support of the work floor 300 can also be used as the support 1 and does not require a special support structure.

  In addition, when the temporary scaffold 900 is further assembled in the direction of the arrow X1 and the direction of the arrow X2 in FIG. 4, the work floor 300 can be similarly formed.

  FIG. 5 is a diagram showing an application example when the reinforcing member 7 is used. FIG. 5 shows an application example for the range of the two supports 1.

  When assembling the temporary scaffold 900 on the support 1, when the number of floors of the scaffold is large, for example, when assembling up to the tenth floor of the building, the load applied to the support 1 increases, and accordingly, the bending applied to the building wall 100 is increased. The moment increases. In particular, the moment concentrates on the upper end portion (the upper end portion in the Z direction in FIG. 5) of the building wall 100 to which the sandwiching portion 3 is attached.

  In such a case, the reinforcing member 7 is attached to each support tool 1 in order to reduce the moment depending on the situation of the building wall 100. For example, a pipe member having the same specifications as the horizontal member 2 of the support 1 can be used for the reinforcing member 7.

  As shown in FIG. 5, the reinforcing member 7 has one end of the reinforcing member 7 attached to the tip of the horizontal member 2 of the supporting tool 1 (the holding portion 3 in the Y direction in FIG. The other end of the reinforcing member 7 is attached to the wall side member 400 attached to the building wall 100 (the portion J2 in FIG. 5). Is done. For attachment of each part, a conventional coupler (for example, an orthogonal clamp, a universal clamp, etc.) used in the assembly of the temporary scaffold 900 can be used (a clamp as shown by J2 in FIG. Used).

  The wall side member 400 is fixed by hitting an anchor on the building wall 100. Moreover, you may make it attach the other end of the reinforcement member 7 directly to the building wall 100 with an anchor etc., without using the wall side member 400. FIG.

  As described above, since the support 1 further includes the reinforcing member 7, a bending moment applied to a part of the building wall 100 can be reduced, and a safe temporary scaffold 900 can be assembled.

  In addition, when the temporary scaffolding 900 is further assembled in the direction of the arrow X1 and the direction of the arrow X2 in FIG. 5, the reinforcing member 7 can be similarly attached.

[Application example when supporting suspended objects]
Next, an application example when the support 1 is used as a tool (support structure) for hanging a safety device or the like when assembling the temporary scaffold 900 will be described. FIG. 6 is a view showing an example in which the support 1 is applied as a support structure for a suspended object.

  When assembling the temporary scaffold 900, it is necessary to ensure the safety of workers, surrounding pedestrians, and the like, and when the apparatus for suspending the temporary scaffold 900 is used from above the temporary scaffold 900, the support 1 is attached to the temporary scaffold. It is attached to the roof of the building where 900 is assembled, etc., so as to support these devices.

  FIG. 6 shows an application example for the range of the two supports 1. Here, each support tool 1 is attached to each wall (parapet, building wall 100) on the roof outer edge of the building by each clamping unit 3. A plurality of support tools 1 are attached at a predetermined interval P (for example, an interval of 1,820 mm) in the direction of arrow X1 and the direction of arrow X2 in FIG.

  The above-described suspension mechanism 200 is attached to the two suspension coupling portions 4 (4A, 4B) of each support 1, and the above-described rail 201 is inserted into each suspension mechanism 200. Although not shown, the rail 201 is continuously laid to a predetermined position in the X direction of FIG.

  In the example shown in FIG. 6, the worker fall prevention device 500 is hung on the rail 201 supported by the suspended coupling portion 4A, and the rail 201 supported by the suspended coupling portion 4B includes an object to the surroundings. The fall prevention device 600 such as the like is suspended.

  Thus, when using the support tool 1 as a support structure for a suspended object, each support tool 1 is first attached to the building wall 100 such as a parapet by the sandwiching portion 3, and then the rail 201 is attached to the rail case 45. After that, the necessary single vehicle 201 and hook 203 are passed through the rail 201. Necessary hanging objects are hung (attached) to the attached hook 203.

  FIGS. 7 and 8 are views showing an embodiment when a safety device is attached using the support 1. FIG. 7 is a front view, and FIG. 8 is a side view. In the example shown in FIGS. 7 and 8, as in the case of FIG. 6 described above, the double rails 201 are provided using the suspension coupling portions 4 </ b> A and 4 </ b> B of the support 1, and the worker 201 falls on each rail 201. The prevention device 500 and the fall prevention device 600 are suspended.

  In this embodiment, as shown in FIG. 7, a plurality of supports 1 are arranged at a predetermined interval P (for example, an interval of 1,820 mm) in the X direction of FIG. 7, and as shown in FIG. Attached to. As shown in FIG. 8, the worker fall prevention device 500 is hung on the inner rail 201 (on the right side in the Y direction in FIG. 8) attached to each support tool 1 via a hook 203. A fall prevention device 600 is suspended from the rail 201 (on the left side in the Y direction in FIG. 8) via a hook 203.

  7 and 8, the worker fall prevention device 500 includes a wire rope 501 attached to the hook 203, a master rope 503 connected under the wire rope 501, a harness 502 attached to the worker 700, a parent A grip 504 that connects the rope 503 and the rope of the harness 502 and a swivel 505 that is a joint portion of the wire rope 501 and the parent rope 503 are provided.

  The worker fall prevention apparatus 500 can move horizontally in the X direction of FIG. 7 because the single vehicle 202 can move along the rail 201. Therefore, the worker fall prevention device 500 moves following the horizontal movement of the worker and does not disturb the movement of the worker. Further, the master rope 503 normally expands and contracts according to the position of the worker 700, but when the operator 700 crashes, the grip 504 does not extend with the master rope 503 interposed therebetween. It becomes like this. Further, the swivel 505 eliminates the rotation (twist) between the wire rope 501 and the master rope 503, thereby preventing so-called return.

  The fall prevention device 600 is a device for preventing an object such as a tool from dropping around the site where the temporary scaffolding 900 is assembled (such as a sidewalk). As shown in FIG. 7 and FIG. A net 601 is provided.

  The net 601 is attached to the hook 203 at a plurality of places like a curtain, and can be opened and closed by moving the hook 203 along the rail 201.

  Thus, although the support tool 1 can be installed above the temporary scaffold 900 and used to suspend the safety device, in this aspect, a lifting winch or the like may be suspended. When the lifting winch is suspended, the hook 201 and the unloading winch may be attached to the suspended coupling portion 4 without providing the rail 201. In this case, unloading can be performed at one place in the horizontal direction.

  Note that the support 1 includes the components described with reference to FIGS. 1 and 2, that is, the horizontal member 2, the first clamping unit 3 a, the second clamping unit 3 b, the suspended coupling unit 4, and the work floor coupling unit. 5 and the anti-slip member 6 are removable (can be disassembled), respectively. Therefore, they are removed during transportation.

  In addition, when the support tool 1 is used as a support structure for the temporary scaffold 900, the temporary scaffold 900 for ten or more stages of the temporary scaffold can be supported by the above-exemplified members and the above-described installation specifications. Proven in strength calculations and tests.

  As described above, since the support 1 according to the present embodiment can be attached to the building wall 100 to support the temporary scaffold 900, the temporary scaffold 900 can be easily temporarily installed even in a place where the temporary scaffold 900 cannot be assembled from the ground. A scaffold 900 can be constructed.

  Moreover, since the support tool 1 can be disassembled into parts that are relatively light and small in size, it has good transportability and is easy to handle on site.

  In addition, the support 1 is compatible with the specifications of the conventional members used in the temporary scaffolding 900, and there is no need to prepare special tools or parts for the connection. Also, handling is easy for the worker 700 who assembles the temporary scaffold 900.

  Moreover, the support tool 1 can be used for various purposes as described above, and it is not necessary to prepare each tool for each application, and is very efficient in terms of manufacturing, management, and handling.

  Specifically, first, the support tool 1 can also serve as a support tool for the work floor 300 when assembling the lowermost temporary scaffold 900.

  The support 1 can also include a reinforcing member 7 that reinforces the building wall 100.

  Further, the support 1 can be used as a support structure for a suspended object, and can support the worker fall prevention device 500, the object fall prevention device 600, and the like.

  The protection scope of the present invention is not limited to the above-described embodiment, but covers the invention described in the claims and equivalents thereof.
