Utility Model Registration No. 3070348

  However, when trying to fix the scaffolding board and the single pipe with a wire, the worker gets on the front side of the scaffolding board spanned over the single pipe and winds the wire around the scaffolding board while crossing the single pipe. There is a risk that the operator may fall from the scaffolding board, and the work of tightening the wire wound around the scaffolding board and the single pipe with the Shino is skillful and labor intensive. There is a problem that it takes time.

  Furthermore, when the scaffold is dismantled, cutting the wire leads to releasing the anchorage between the scaffold plate and the single pipe, so the cut wire cannot be reused at other sites and must be discarded. There is also a problem.

  Accordingly, an object of the present invention is to provide a scaffold plate fixture that can safely and easily fix a scaffold plate spanned over a single tube of a scaffold frame to a single tube and that can be used repeatedly. It is in.

  In order to solve the above-described problems, the invention according to claim 1 is a scaffold plate fixing tool for fixing two adjacent scaffold plates spanned on a single tube constituting a scaffold frame to the single tube. A horizontal U-shaped engagement member that can be engaged with a single pipe from the lateral direction, and at least an upper portion that is connected to the engagement member so as to rise from the upper surface of the horizontal U-shaped engagement member. A shaft member having a male screw portion formed on the outer peripheral surface, and a pressing plate into which the male screw portion of the shaft member is screwed, so that the pressing plate is adjacent to both side plates of adjacent scaffolding plates. In a state where the engaging member is engaged with the single pipe from the lateral direction between the scaffolding plates, the side plates of the two adjacent scaffolding plates are pressed against the single pipe by rotating and screwing the pressing plate. Thus, a fixing device for a scaffolding plate to be fixed is provided.

  The invention according to claim 2 is the scaffold plate fixture according to claim 1, characterized in that the pressing plate is provided with a locking portion for rotational operation on the upper surface thereof. .

  The invention according to claim 3 is an operation jig for rotating the pressing plate in the fixing device for the scaffolding plate according to claim 2, wherein the upper end of the shaft member protrudes from the pressing plate. A base plate placed on the pressing plate so as to be rotatable about a shaft member inserted through the insertion hole; and a lower surface of the base plate, An operation treatment comprising: a locked portion that engages with a locking portion of the pressing plate; and an operation portion that is provided on an upper surface side of the base plate and is used to rotate the base plate. It provides tools.

  In order to solve the above-mentioned problem, the invention according to claim 4 is a scaffold for fixing the outer edge portion of the scaffold plate at the extreme end position spanned on the single tube constituting the scaffold frame to the single tube. A plate-fixing tool, which is a U-shaped engaging member that can be engaged with a single tube from the side, and is connected to the engaging member so as to rise from the upper surface of the engaging member that is U-shaped. A cross section in which the shaft member is inserted into a portion corresponding to the upper surface of the scaffold plate, which is disposed at the upper surface corner portion of the outer peripheral edge of the scaffold plate, and the shaft member having a male screw portion formed on at least the upper outer peripheral surface An inverted L-shaped pressing member, and a nut screwed into a male screw portion of the shaft member in a state of being inserted through the pressing member, are arranged along the upper surface corner portion of the outer edge portion of the scaffold plate. In the state where the engaging member is engaged with the single pipe from the lateral direction, the nut is screwed It is one in which the pressing member to provide a fastener of the scaffold plate outer edge and be fixed by pressing the single pipe scaffold plate.

  Further, the invention according to claim 5 is the scaffold plate fixture according to claim 4, wherein the corner of the pressing member corresponds to the side end surface of the scaffold plate from the portion corresponding to the upper surface of the scaffold plate. A long hole through which the shaft member is inserted is formed over the portion.

  In the scaffold plate fixing device according to the first aspect of the present invention, when the engaging member is engaged with the single tube from the lateral direction, the pressing plate is positioned on the upper side of the scaffold plate and the side plate is moved along the side edge. Since it is only necessary to engage the engagement member with the single pipe by sliding the slide, the work is performed on the front side of the scaffold board that spans the single pipe, as in the case of fixing the scaffold board and the single pipe with a wire. There is no need for the operator to lean out, and the risk of the operator falling from the scaffolding plate is greatly reduced.

  Further, in order to fix the side edge portions of two adjacent scaffold plates to a single tube using the scaffold plate fixing tool, both the adjacent scaffolds are engaged with the engagement member engaged with the single tube. Since it is only necessary to rotate and screw the pressing plate protruding from the side edge of the plate, the operator does not need skill and labor, and can easily fix the scaffolding plate to the single tube in a short time.

  Also, when dismantling the scaffold, rotate the pressing plate in the reverse direction to release the pressing state of the scaffolding plate, then slide the engagement member in the direction away from the single tube to release the engagement with the single tube Since it can be removed simply, the fixing work of the scaffolding plate to the single pipe can be easily performed, and the removed fixture can be used repeatedly at other construction sites.

  Further, in a state where the scaffold plate is fixed to the single tube using the scaffold plate fixing tool, the pressing plate is placed on the scaffold plate, and the upper end portion of the shaft member protrudes from the central portion of the pressing plate. However, if the length of the shaft member is set so that the protruding amount is about 5 to 2 mm, it will not be an obstacle for the worker walking on the scaffolding board.

  In particular, like the fixing device for the scaffolding plate of the invention according to claim 2, if an engaging portion for rotational operation is provided on the upper surface of the pressing plate, the operating jig of the invention of claim 3 is attached to the pressing plate. The base plate is rotated by operating the operation portion of the operation jig after placing the engagement portion on the lower surface of the base plate of the operation jig and engaging the engagement portion of the pressing plate. Accordingly, the pressing plate rotates and the pressing plate can be easily tightened or loosened, so that workability is improved.

  Further, in the scaffold plate fixture of the invention according to claim 4, when the engagement member is engaged with the single tube from the lateral direction so that the pressing member is along the upper surface corner portion of the outer edge portion of the scaffold plate, Since it is only necessary to engage the single pipe by pushing the engaging member from the rear side of the single pipe to the front side, it is stretched over the single pipe as in the case where the scaffolding plate and the single pipe are fixed with a wire. There is no need for the operator to get on the front side of the scaffold board, and the risk of the operator falling from the scaffold board is greatly reduced.

  Also, in order to fix the outer edge of the scaffolding plate to the single tube using this scaffolding plate fixture, the operator only has to screw the nut after engaging the engagement member with the single tube. The scaffolding plate can be fixed to the single tube easily and in a short time without requiring skill and labor.

  Also, when disassembling the scaffold, after loosening the nut and releasing the pressed state of the scaffold plate, it is only necessary to slide the engagement member away from the single pipe to release the engagement with the single pipe. The anchor plate can be easily released from the single tube, and the removed fixture can be used repeatedly at other construction sites.

  Further, in a state where the scaffold plate is fixed to the single tube using the scaffold plate fixing tool, the shaft is pivoted to a portion corresponding to the upper surface of the scaffold plate in the pressing member disposed on the upper surface corner of the outer edge portion of the scaffold plate. The upper end of the member will protrude, but since the protruding position is the outer edge of the scaffolding plate at the extreme end position, the protruding part of the shaft member may be an obstacle for the worker walking on the scaffolding plate. Absent.

  In particular, the shaft member is inserted from the portion corresponding to the upper surface of the scaffold plate at the corner portion of the pressing member to the portion corresponding to the side end surface of the scaffold plate, as in the scaffold plate fixture according to the invention of claim 5. If the long hole to be formed is formed, the insertion position of the shaft member can be changed without removing the nut, and the portion corresponding to the upper surface of the scaffold plate is changed to the portion corresponding to the side end surface of the scaffold plate. The pressing member can be used in a state where the portion corresponding to the side end surface of the plate is replaced with the portion corresponding to the upper surface of the scaffold plate. Therefore, if the lengths of the protruding portions of the two portions are set to different lengths in accordance with the thickness of the scaffold plate to be used, it is possible to deal with scaffold plates having different thicknesses.

  First, as shown in FIGS. 5 (a) to 5 (c), after a new scaffold plate SP is placed over the single pipe P so that one side edge is brought into contact with the fixed scaffold plate SP, 6A to 6C, the pressing plate 13 of the fixture 1 is moved to the uppermost position of the shaft member 12, and the pressing plate 13 is positioned above the scaffolding plate SP. By sliding the fixtures 1 along the other side edge of the scaffolding plate SP, the respective engaging members 11 are respectively attached to the two single tubes P positioned at both ends in the longitudinal direction of the scaffolding plate SP. Engage.

  Subsequently, as shown in FIGS. 7 (a) to 7 (c), after the new scaffold plate SP is stretched over the single pipe P so that one side edge thereof is brought into contact with the fixture 1. 8 (a) to 8 (c), the operation jig 3 is inserted into the insertion hole 31a through the upper end portion (stopper member 12a) of the shaft member 12 of the fixture 1, and a pair of convex portions. 32 is placed on the pressing plate 13 with the fitting hole 13b of the pressing plate 13 of the fixture 1 being fitted, and a tool such as an electric screwdriver ED is placed on the operating portion 33 of the operating jig 3. When the pressing plate 13 of the fixture 1 is tightened by rotating using the two scaffold plates SP adjacent to each other by the pressing plate 13 of the fixture 1 as shown in FIGS. These side edges are pressed by the single pipe P, and two adjacent scaffolding plates SP are fixed to the single pipe P via the fixture 1. In addition, in the state which fixed the scaffold board SP to the single pipe P using the fixing tool 1, the length of the shaft member 12 including the stopper member 12a is set so that the protruding amount of the upper end portion of the shaft member 12 is about 5 to 2 mm. Is set.

Since the engagement member 11 may be engaged with the single pipe P by sliding along the pipe, the scaffold plate spanned over the single pipe as in the case where the scaffold board and the single pipe are fixed with a number wire. There is no need for the operator to lean forward and the risk of the operator falling from the scaffold plate is greatly reduced.

  In addition, in order to fix the side edge portions of the two adjacent scaffold plates SP to the single pipe P using the fixing tool 1, as described above, the engagement member 11 is engaged with the single pipe P. Therefore, since it is only necessary to rotate and screw the pressing plate 13 projecting to the side edges of both adjacent scaffolding plates SP, the operator does not need skill and labor and can easily remove the scaffolding plate in a short time. Can be fixed to the tube.

  Further, when dismantling the scaffold, the pressing plate 13 is rotated in the reverse direction to release the pressing state of the scaffolding plate SP, and then the engaging member 11 is slid in the direction away from the single tube P to be separated from the single tube P. Since it can be removed simply by releasing the engagement, the fixing work of the scaffold plate SP with respect to the single pipe P can be easily performed, and the removed fixture 1 can be repeatedly used at other construction sites. .

  In particular, in this fixture 1, as described above, the pressing plate 13 can be easily tightened or loosened using the operation jig 3, so that the workability is good. Since the suspension hole 34 is formed, the worker can carry the operation jig 3 in a state where it is hooked on a carabiner or the like hung on the waist, and the portability is also good.

  Further, since the pressing plate 13 of the fixture 1 and the base plate 31 of the operation jig 3 are circular and do not have corners on the periphery, a tool such as an electric screwdriver is used for tightening or loosening. Even when the pressing plate 13 is rotated, the operator is not easily damaged by hands, fingers, and the like, and the fixing work and the fixing releasing work of the scaffold board SP can be performed safely.

  Further, in a state where the scaffolding plate SP is fixed to the single tube P using the fixing tool 1, the pressing plate 13 is placed on the scaffolding plate SP, and the upper end portion of the shaft member 12 is at the center of the pressing plate 13. Although it protrudes, since the length of the shaft member 12 is set so that the protruding amount is about 5 to 2 mm, it does not become an obstacle for the worker walking on the scaffolding plate SP.

  10 (a) to 10 (d) show a scaffolding plate fixing tool 2 for fixing the outer edge portion of the scaffolding plate at the extreme end position spanned on the single tube P constituting the scaffolding frame to the single tube P. Is shown. As shown in the figure, the fixing member 2 is disposed at the upper corner portion of the outer edge of the scaffolding plate, and the engaging member 21 and the shaft member 22 similar to the engaging member 11 and the shaft member 12 of the fixing device 1. The shaft member 22 is inserted into a portion corresponding to the upper surface of the scaffold plate, and the cross-sectionally inverted L-shaped pressing member 23 is inserted into the male screw portion of the shaft member 22 while being inserted into the pressing member 23. It consists of a nut 24. A stopper member 22a having a larger diameter than the screw hole of the nut 24 is fixed to the upper end portion of the shaft member 22 so that the nut 24 screwed in the state of being inserted into the pressing member 23 is not dropped. The length of the member 22 is set to be about 8 mm longer than the length of the shaft member 12 of the fixture 1.

  As shown in FIGS. 11A and 11B, the pressing member 23 has a vertical plate 23a along the side end surface of the scaffolding plate, and a horizontal plate extending horizontally from the upper end of the vertical plate 23a and along the upper end surface of the scaffolding plate. The length (height) L1 of the vertical plate 23a is set to be slightly shorter than the thickness of the scaffold plate, and the overhang length L2 of the horizontal plate 23b is the thickness of the plate 23b. It is set slightly shorter than the thickness of other different scaffolding plates.

  In addition, a long hole 23c through which the shaft member 22 is inserted is formed at the corner portion of the pressing member 23 from the vertical plate 23a to the horizontal plate 23b, as shown in FIGS. 12 (a) and 12 (b). In this way, the insertion position of the shaft member 22 can be changed by rotating the pressing member 23 in the direction indicated by the arrow in FIG. , The pressing member 23 can be used in a state in which the vertical plate 23a is replaced with the portion corresponding to the upper surface of the scaffolding plate and the horizontal plate 23b is replaced with the portion corresponding to the side end surface of the scaffolding plate. ing.

  About the fixing method of the scaffold board which fixes the outer edge part of the scaffold board of the extreme end position spanned on the single pipe P using the fixing tool 2 comprised as mentioned above to the single pipe P. FIGS. This will be described with reference to FIG.

  First, as shown in FIGS. 13 (a) to 13 (c), after the last scaffold plate SP is stretched over the single tube P so that one side edge is brought into contact with the fixed scaffold plate SP, As shown in FIGS. 14A to 14C, the nut 24 of the fixture 2 is moved to the upper end side of the shaft member 22, and the horizontal plate 23b of the pressing member 23 is positioned above the scaffold plate SP. By sliding the two fixtures 2 along the other side edge of the scaffolding plate SP, the two single tubes P positioned at both ends in the longitudinal direction of the scaffolding plate SP. Are engaged with each other.

  Subsequently, as shown in FIGS. 15A to 15C, when the nut 24 is tightened by rotating the tool 24 using a tool such as an electric screwdriver ED, as shown in FIGS. 16A to 16C. Further, the outer edge portion of the endmost scaffold plate SP is pressed against the single tube P by the pressing member 23 (horizontal plate 23b) of the fixture 2, and the endmost scaffold plate SP is connected to the single tube via the fixture 2. Fixed to P.

  As described above, in the fixture 2, when the engaging member 21 is engaged with the single pipe P from the lateral direction, the pressing member 23 is disposed at the upper corner of the outer edge of the scaffolding plate SP, and the scaffold Since the engaging member 21 may be engaged with the single pipe P by sliding along the side edge of the plate SP, it is hung on the single pipe as in the case where the scaffolding plate and the single pipe are fixed with a wire. There is no need for the operator to get on the front side of the passed scaffold board, and the risk of the operator falling from the scaffold board is greatly reduced.

  Further, in order to fix the outer edge portion of the scaffold plate SP to the single pipe P using the fixing tool 2, it is only necessary to screw the nut 24 after engaging the engaging member 21 with the single pipe P. The operator does not require skill and labor, and can easily fix the scaffolding plate to the single pipe in a short time.

  Further, when the scaffold is disassembled, the nut 24 is loosened to release the pressing state of the scaffold plate SP by the pressing member 23, and then the engaging member 21 is slid in a direction away from the single pipe P to be connected to the single pipe P. Since it is only necessary to release the engagement, the work of releasing the fixation of the scaffold plate SP with respect to the single pipe P can be easily performed, and the removed fixture 2 can be repeatedly used at other construction sites.

  Further, in a state where the scaffolding plate SP is fixed to the single tube P using the fixture 2, the shaft member is placed on the horizontal plate 23b of the pressing member 23 disposed at the upper surface corner of the outer edge of the scaffolding plate SP. The upper end portion of 22 projects, but the projecting position is the outer edge portion of the scaffold plate SP at the extreme end position, so that the projecting portion of the shaft member 22 is an obstacle to the worker walking on the scaffold plate SP. It will never be.

  In particular, as described above, the fixing device 2 can change the insertion position of the shaft member 22 without removing the nut 24. When using another scaffolding plate having a different thickness, the vertical plate 23a is used. Since the pressing member 23 can be used in a state where the horizontal plate 23b is replaced with a portion corresponding to the side end surface of the scaffolding plate in a portion corresponding to the upper surface of the scaffolding plate, a plurality of types having different thicknesses It can correspond to a scaffold board.

  In addition, in the fixing tool 1 mentioned above, although the press plate 13 is tightened or loosened using the operation jig 3, it is not limited to this, A manual tool or an electric tool is used. Thus, the pressing plate 13 itself may be directly rotated.

  Moreover, in the fixing tool 1 mentioned above, although the engaging member 11 is provided with the linear parts 11b and 11b each protruding horizontally from the upper and lower ends of the semicircle part 11a engaged with the single pipe P, it is limited to this. However, the straight portion may be omitted. However, if the straight portions 11b and 11b are provided, it is possible to obtain an effect that the engaging member 11 engaged with the single pipe P is not easily dropped from the single pipe P.

  Moreover, in the fixing tools 1 and 2 described above, the engaging members 11 and 21 are formed of a metal material having a square cross section. However, the present invention is not limited to this, and the engaging members are formed of a metal material having a circular cross section. It is also possible to form However, if the engaging members 11 and 21 are formed of a metal material having a quadrangular cross section, when the engaging member 11 is engaged with the single pipe P, it is difficult for the single pipe P to fall off. There is an effect that the fixtures 1 and 2 are difficult to drop during work.

  Further, in the fixing device 2 described above, the long hole 23c through which the shaft member 22 is inserted is formed at the corner of the pressing member 23. However, the present invention is not limited to this, and the horizontal plate 23b or the horizontal plate 23b and It is also possible to form a circular hole through which the shaft member 22 can be inserted in both of the vertical plates 23a. However, when the circular holes are formed in both the horizontal plate 23b and the vertical plate 23a in order to correspond to the scaffold plates having different thicknesses, the shaft member 22 is provided in one of the two circular holes depending on the scaffold plate. Since it is necessary to insert again, it is necessary to abbreviate | omit a stopper member or to provide a detachable stopper member so that the nut 24 can be removed from the shaft member 22. FIG.

  Further, in the fixing device 2 described above, the length of the vertical plate 23a of the pressing member 23 (the horizontal plate 23b when the horizontal plate 23b is used vertically as shown in FIG. 12B) is used. The thickness is set to be slightly shorter than the thickness of the scaffold plate, but the length of the vertical plate 23a (or the horizontal plate 23b when the horizontal plate 23b is used vertically) is longer than the thickness of the scaffold plate. However, if the surplus length is about 5 mm, by tightening the nut 24, the horizontal plate 23b (or the vertical plate 23a when the horizontal plate 23b is used in a vertical position) is lowered toward the tip side and inclined. Since the pressing member 23 is inclined so that the tip of the horizontal plate 23b or the vertical plate 23a presses the upper surface of the scaffold plate SP, the scaffold plate can be fixed without any particular problem.

  The fixture and the operation jig of the present invention can be used when the scaffold plate is fixed to a single pipe.
