Description

  The present invention relates to a scaffold installation device that is attached to a liner plate and is useful for installing a scaffold on the side wall surface of the liner plate.

  In the electric power industry, when installing a high structure such as a steel tower on the slope of a mountain, for example, as shown in Patent Documents 1 to 4, a liner plate is used for foundation work such as earth retaining. When installing a structure on the slope of a steep mountain, level the slope of the mountain in advance and flatten it, and then excavate the shaft at the place where the structure is to be installed to place the liner plate. However, in recent years, from the standpoints of reducing the cost of installing the structure and protecting the natural environment, a shaft is directly excavated on a sloping slope to arrange the liner plate.

As for the structure of the scaffold for facilitating the work in the mine in which such a liner plate is arranged, a work table, a work scaffold, and a work scaffold as shown in Patent Documents 1 to 3 are known. .
Further, as shown in Patent Document 4, when installing a landing for trapping at the uppermost part of the liner plate, in addition to the scaffold placed in the mine of the liner plate, workers are also placed on the outside of the liner plate. A configuration in which steps for raising and lowering are arranged is also known.

  By the way, when a liner plate is placed on a shaft provided on a sloping slope, the liner plate is exposed greatly on the lower side of the slope, so that the liner plate can be used from the standpoint of ensuring the safety of measurement work and photography work. There is a demand to install a scaffold also on the outer wall surface of the exposed side. In this regard, in the structure of the work table, the work scaffold, and the work scaffold shown in the conventional Patent Documents 1 to 3, since the scaffold is installed on the inner wall surface of the liner plate, the structure is provided outside the liner plate. It is difficult to adopt as it is.

  Further, in the structure of the landing for trapping shown in Patent Document 4, the step is to support the support plate on the uppermost flange of the liner plate, and to superimpose a hinge on it and fix it with bolts and nuts. It cannot be used on the lower side of the slope where the exposed dimension of the liner plate from the shaft becomes large, and it cannot be used when a scaffold is to be arranged over a predetermined range of the outer periphery of the liner plate.

  Furthermore, if it is possible to combine a ladder for raising and lowering the scaffold with respect to the scaffolding and a handrail for raising and lowering as required, the installation time of various instruments for setting the scaffolding on the liner plate can be shortened overall. In addition, the cost can be reduced by sharing a plurality of instruments.

  The present invention has been made in view of such circumstances, and allows a scaffold to be installed on the side of the wall surface of the liner plate, and is optimal even if there is a difference in the exposed dimension from the top of the liner plate to the ground surface. Scaffolding can be installed at any position, and it can be used when installing the scaffolding regardless of whether the liner plate is inside or outside. The main problem is to provide a scaffold installation device for liner plate attachment that can be provided.

  To achieve the above object, a scaffolding apparatus for installing a liner plate according to the present invention is capable of adjusting the position of a first component member attached to an upper end portion of a standing liner plate and the first component member. A scaffold installation device configured to be fixed and capable of installing a scaffolding plate, wherein the first component is engaged and fixed to an upper end portion of the liner plate. Proximity fixing portion, a position adjustment portion that extends vertically and abuts against the wall surface of the liner plate and that allows the fixing position of the second component member to be adjusted in the vertical direction, and is close to the locking fixation portion The second component member is vertically extended along the wall surface of the liner plate, and is detachably fixed to the position adjustment unit. Base body A protruding portion provided on the base portion and protruding in a direction away from the liner plate so that the scaffolding plate can be placed thereon, and a pole mounting provided at a front end of the protruding portion in the protruding direction and capable of mounting a pole It is characterized by providing a part.

  Here, even if the overhanging portion is constituted by a main frame that protrudes substantially vertically from the base portion and a sub-frame that supports the main frame, it is constituted only by a frame material that protrudes substantially vertically from the base portion. You may do it.

  Therefore, according to such a scaffolding apparatus for installing a liner plate, if the second constituent member is fixed by adjusting the vertical position at the side of the wall surface of the liner plate by the first constituent member, the second constituent member Since the overhanging part protrudes in a direction away from the liner plate at a desired height and the scaffolding plate can be placed, by attaching a plurality of such scaffold setting devices, the overhanging part is provided on the side wall of the liner plate. It is possible to place the scaffolding plate between them and install the scaffolding in the circumferential direction of the liner plate.

  Here, a plurality of through holes are formed in the position adjusting portion of the first constituent member in the vertical direction, and the through holes formed in the base portion of the second constituent member and the arbitrary through holes of the position adjusting portion are provided. The base portion may be detachably fixed to the position adjusting portion by aligning and inserting a fixing tool into the aligned through holes.

  According to such a configuration, the height of the scaffold can be adjusted so that the scaffold plate does not hit the inclined surface when placing the scaffold plate on the overhanging portion of the second component member, In adjacent scaffold installation devices, the ends of the scaffolding plates overlap each other by shifting the height of the overhanging portion of one second component member up or down relative to the height of the overhanging portion of the other second component member. Even in such a case, it is avoided that the scaffolding plate is inclined.

  As a specific aspect of the above configuration, the locking and fixing portion of the first component member has an abutting portion that protrudes so as to be locked to the flange of the upper end portion of the liner plate at the upper portion of the position adjusting portion, and this The contact portion extends downward from the tip of the contact portion along the wall surface of the liner plate, and includes an insertion portion that sandwiches the liner plate together with the position adjustment portion, and the contact portion is fixed to the flange by a fixing means. Configuration is conceivable.

  In such a configuration, the position adjustment portion of the first component member can be formed in a long and flat shape extending vertically, and the base portion of the second component member can be superimposed on the position adjustment portion. It may be formed into a long and flat plate extending vertically.

  As another specific aspect, the locking fixing portion of the first component member is configured by an abutting portion that protrudes so as to be locked to the flange of the upper end portion of the liner plate at the upper portion of the position adjusting portion. The abutting portion may be fixed to the flange by a fixing means.

  In such a configuration, the position adjusting portion of the first component member is constituted by a pair of guide plates extending vertically, and the base portion of the second component member is vertically arranged between the guide plates. It is good to comprise with the square material accommodated so that sliding is possible.

  Furthermore, in the scaffold installation device for liner plate attachment according to the present invention, a plurality of first and second constituent members are attached to the liner plate, and a pair is attached to the pole attaching portion of two adjacent second constituent members. It is also possible to mount the pole of a ladder configured to have a pole formed and a scaffold for raising and lowering built between the poles, and a plurality of first and second constituent members are attached to the liner plate. You may make it mount | wear with the said pole mounting | wearing part of the two adjacent 1st structural members with which the said pole of the handrail for raising / lowering which makes a pair comprised by connecting a pole is mounted | worn. Here, the ladder and the pole of the raising and lowering handrail may be fixed in advance to the pole mounting portion of the second component member, or may be detachably mounted.

  With these configurations, a ladder provided with a lifting platform can be used when moving up and down with respect to the scaffolding installed on the side wall of the liner plate, and the ladder plate straddles the scaffolding plate from the side wall of the liner plate. When moving to the opposite side or moving in the opposite direction, it is possible to use lifting hand rub.

  As described above, according to the present invention, the scaffolding device for attaching a liner plate is fixed to the first component member attached to the upper end portion of the liner plate and the second component member so that the position can be adjusted. A locking fixing portion for locking and fixing the first component to the upper end portion of the liner plate, and a position adjusting portion that extends vertically and contacts the wall surface of the liner plate And a pole mounting portion provided in the vicinity of the locking and fixing portion, and the second component member is vertically extended along the wall surface of the liner plate, and is attached to and detached from the position adjusting portion. A base part that can be fixed, a projecting part that protrudes from the base part and on which the scaffolding plate can be placed, and a pole mounting part that is provided at the front end of the projecting direction of the projecting part. Because the first and second such Of the components, by installing two or more liner plates, it is possible to place the scaffold any height in the wall beside for any outer or inner liner plate.

Moreover, when mounting a scaffold with respect to the overhang | projection part of the 2nd component member which comprises a scaffold installation apparatus, the dimension from the uppermost part of a liner plate to a scaffold can be adjusted so that a scaffold board may not touch an inclined surface. In addition, since it is possible to relatively shift the overhanging portion between adjacent scaffold installation devices, the height of one overhanging portion is made lower than the height of the other overhanging portion. Since the edges of the scaffolds overlap each other, it is possible to prevent the scaffolds from being inclined and the working environment from becoming worse.
Furthermore, since the first component member and the second component member are each provided with a pole mounting portion, it is possible to install a handrail pole, and a person who works on the scaffold falls down. It becomes possible to avoid danger.

  In particular, the locking and fixing portion of the first component member has a contact portion protruding so as to be able to be locked to the flange at the upper end portion of the liner plate, and downward from the tip of the contact portion along the wall surface of the liner plate. If the fixing means is loose, the fixing means is fixed to the flange of the liner plate. Even if the fixing by the fixing means is forgotten, the fixing can be performed without fear of dropping off, and the position adjusting portion of the first component member is formed in a long and flat shape extending vertically, and the second By forming the base portion of the component member in a long and flat shape extending vertically so as to be superposed on the position adjusting portion, a simple structure can be obtained.

  Further, in particular, the locking and fixing portion of the first component member is configured by a contact portion projecting so as to be able to be locked to the flange at the upper end portion of the liner plate at the upper portion of the position adjusting portion, and the contact portion is a flange. If the fixing means is fixed to the flange, the structure for fixing to the flange can be simplified, and the position adjusting portion of the first component member is a pair of guides extending vertically. By configuring the base portion of the second component member with a square member that is slidably accommodated between the guide plates, the second component member is moved up and down with respect to the first component member. Since the first fixing member and the second fixing member can be fixed easily, the base portion of the second fixing member is fixed by a pair of guide plates. Therefore, it is possible to obtain a strong fixing structure.

  Further, a plurality of first and second component members are mounted on the liner plate, and a pair of poles and a lifting scaffold constructed between these poles are mounted on the pole mounting portions of two adjacent second component members. The ladder can be used when the elevator is raised and lowered with respect to the scaffolding beside the wall surface of the liner plate. A plurality of constituent members are mounted on the liner plate, and the poles of the handrails for raising and lowering which are formed by connecting the poles are mounted on the pole mounting portions of the two adjacent first constituent members. Then, when moving from the scaffolding on the wall side of the liner plate to the opposite side across the liner plate, or vice versa, it is possible to use the lifting handrail, and the ladder and the lifting handrail can be used. Establishment It is possible to utilize the components of the scaffold installation apparatus for installation time to the liner plate are generally shorter, it is possible to achieve the cost reduction by common use of the instrument.

  The locking and fixing portion 25 extends from the upper end of the position adjusting portion 22 in the thickness direction with respect to the liner plate 4, and comes into contact with a flange portion 4 a at the upper end portion of the liner plate 4 so as to be locked. The insertion portion 25b extends downward along the wall surface of the liner plate 4 from the tip of the contact portion 25a. It is preferable that the length of the contact portion 25a is substantially the same as the width of the flange 4a of the liner plate 4. The contact portion 25 a is formed with a through hole 26 that communicates with the connecting bolt hole 5 of the flange 4 a when the contact plate 25 is placed on the flange 4 a at the top of the liner plate 4. A locking piece 27 extending toward the liner plate 4 extends at the lower end portion of the insertion portion 25b and can be inserted into a recess formed on the wall surface of the liner plate 4. As shown in FIG. 1, the locking piece 27 is inserted into the locking piece 24 of the position adjusting unit 22 when the position adjusting unit 22 is installed in contact with the outer wall surface of the liner plate 4. It is inserted into the concave portion of the inner wall surface at a position shifted in the axial direction (upper side in this embodiment) of the liner plate 4 with respect to the concave portion of the outer wall surface.

  The pole mounting portion 28 is fixed to the upper end of the position adjusting portion 22, that is, the base 28a fixed to the surface of the position adjusting portion 22 opposite to the side on which the liner plate 4 abuts, and fixed to the upper portion of the base 28a. The pole mounting pipe 28b is constructed by inserting the pole 30 into the pole mounting pipe 28b and the base 28a from above and tightening the pole fixing bolt 29 provided on the side. Is fixed to the pole mounting portion 28 in a detachable manner.

  When the mounted pole 30 is a pole for attaching a safety rope or the like, a pole provided with a through hole 31 through which a string-like member 38 (shown in FIG. 3) such as a rope is inserted at the tip is used. Good. The pole 30 is preferably detachably attached to the pole mounting pipe 28b or the like, but may be fixed to the pole mounting pipe 28b or the like in advance.

  On the other hand, the component member 9 of the liner plate-attached scaffold installation device 1 includes a base portion 10, an overhang portion 13, and a pole mounting portion 16, as shown in FIG.

  The base portion 10 is a long and thin flat plate that extends vertically, and has a plurality of (six in this embodiment) through-holes 11 from the vicinity of the upper end in the longitudinal direction to the middle thereof. At the lower end in the longitudinal direction, an engaging portion 12 that can engage with the convex portion of the wall surface of the liner plate 4 is formed. In this example, the engaging portion 12 includes an extending piece 12 a that extends obliquely upward from the base portion 10 and an extending piece 12 b that extends obliquely downward from the base portion 10. The through holes 11 in the base portion have the same inner diameter as the through holes 23 in the position adjusting portion 22 and are formed at the same pitch.

  Further, the overhanging portion 13 protrudes from the portion located between the through hole 11 and the engaging portion 12 of the base body portion 10 in a direction substantially away from the liner plate, and has a main scaffold installation surface 14a on the upper side. A frame 14 and a subframe 15 projecting obliquely upward from the lower end of the base body 10 on the side opposite to the side on which the engaging portion 12 is provided. A scaffolding plate, which will be described later, is placed on the main frame 14. Has a role as a support for reinforcement. If the strength of the main frame 14 is sufficient, the sub frame 15 may not be provided.

  The pole mounting portion 16 includes a base 16a to which both ends of the main frame 14 and the sub frame 15 of the overhanging portion 13 are connected, and the extending direction of the base portion 10 from the base 16a, that is, the liner plate 4 And a pole mounting pipe 16b extending along the axial direction. By inserting a pole 18 into the pole mounting pipe 16b and the base 16a and tightening a pole fixing bolt 17 provided on the side. The pole 18 is fixed to the pole mounting portion 16.

  In addition, when the pole 18 to be mounted is a pole for attaching a safety rope, a pole provided with a through hole 19 through which a string-like member 37 (shown in FIG. 3) such as a rope is inserted at the tip is used. Good. The pole 18 is preferably detachably attached to the pole mounting pipe 16b or the like, but may be fixed to the pole mounting pipe 16b or the like in advance.

  When the scaffold is installed using the above-described component installation scaffold installation device 1 with the liner plate on the outer wall surface of the liner plate below the inclined surface of the temporary structure 3 as shown in FIG. The following work may be performed.

  First, the liner 21 is sandwiched from the opening side of the temporary structure 3 (above the liner plate 4) while the component member 21 is slightly opened between the locking piece 24 and the locking piece 27. In this way, the contact portion 25a is lowered until it abuts against the flange 4a at the top of the liner plate 4. As a result, the locking piece 24 and the locking piece 27 are inserted into the concave portion of the outer wall surface and the concave portion of the inner wall surface of the liner plate 4 by a restoring force or the like and reliably engaged, and the component member 21 is prevented from falling off. The

  Next, the component member 21 is moved along the circumferential direction of the liner plate 4, the through hole 26 of the contact portion 25 a is communicated with the connecting bolt hole 5 of the flange 4 a close to a desired position, and the bolt 7 is moved from the upper side. The nuts 8 are screwed into the holes 26 and 6 and tightened. This prevents the component member 21 from inadvertently moving along the circumferential direction of the liner plate 4. Moreover, since the bolt 7 and the nut 8 that fix the component member 21 and the liner plate 4 can use the bolt 7 and the nut 8 that fix the liner plates 4 to each other, it is possible to achieve common parts. Become.

  Further, the engaging portion 12 of the base portion 10 of the component member 9 is engaged with the convex portion on the outer wall surface of the liner plate 4, and the through hole 23 of the position adjusting portion 22 is further convex on the outer wall surface of the liner plate 4. The through hole 11 of the base body part 10 and the through hole 23 of the position adjustment part 22 are selected so as to satisfy the condition not to be blocked by the base part 10, and the through hole 11 of the selected base part 10 and the position adjustment part 22 are passed through. The base portion 10 of the constituent member 9 is overlaid on the position adjusting portion 22 of the constituent member 21 so that the hole 23 communicates with each other, and then a bolt 32 is inserted into both the through holes 11 and 23, and a nut 33 is inserted into this. Screw in and tighten.

  In this way, after one liner plate attachment scaffold installation device 1 is attached to the liner plate 4 using a pair of constituent members 21 and 9, another liner plate attachment scaffold is provided at a predetermined interval. When the installation device 1 (component members 21 and 9) is attached, the liner plate attached later is provided by the thickness of the scaffold plates 35 and 36 than the component member 9 of the liner plate attachment scaffold installation device 1 attached earlier. The structural member 9 of the scaffold installation device 1 is attached while being shifted in the axial direction of the liner plate 4. Then, the scaffold plates 35 and 36 are placed on the scaffold installation surface 14 a of the overhanging portion 13 of the adjacent component member 9. Accordingly, when the scaffolding plates 35 and 36 are placed on the scaffold installation surface 14a of the overhanging portion 13, the scaffolding plates 35 and 36 are prevented from being inclined even if the scaffolding plates overlap each other.

  And an outer handrail is formed by passing the string-like member 37 such as a rope through the through hole 19 of the pole 18 attached to the pole mounting portion 16 of each attached component member 9, and each attached component An inner handrail is formed by passing a string-like member 38 such as a rope through the through hole 31 of the pole 30 attached to the pole mounting portion 28 of the member 21.

  Therefore, according to the above configuration, the component member 9 is fixed to the liner plate 4 via the component member 21, and the scaffolding installation device 1 with the liner plate is attached to the side of the outer wall surface of the liner plate 4. The overhanging portion 13 on which 35 and 36 are placed is arranged in a state of protruding from the outer wall surface of the liner plate 4. For this reason, when the diameter dimension of the liner plate 4 is small, when the scaffold cannot be arranged inside the liner plate 4 or because it is arranged, it becomes difficult to go in and out of the liner plate 4 or work inside the liner plate 4. The inconvenience that makes it difficult to do is resolved. In addition, the mounting position of the liner plate-attached scaffold installation device can be adjusted as appropriate according to the topography of the site.

  In addition, on the outer side of the scaffold installation surface 14 a with respect to the liner plate 4, a pole mounting portion 16 on which an outer handrail pole 18 or the like can be mounted is disposed on the liner plate 4 on the inner side of the scaffold installation surface 14 a. In this case, since the pole mounting portion 28 that enables mounting of the inner handrail pole 30 and the like is disposed simultaneously with the installation of the overhanging portion 13, the work can be simplified and speeded up. Furthermore, when the dimension L1 (see FIG. 1) from the opening end of the liner plate 4 to the overhanging portion 13 is 75 cm or more, the liner plate 4 itself can be used as a handrail for the inside. In some cases, it is possible to remove the pole 30 from the pole mounting portion 28 so as not to hinder the work.

  By the way, the above-described scaffold installation device 1 with a liner plate can be used when climbing from the ground to the scaffolding plates 35 and 36, or descending from the scaffolding plates 35 and 36 to the ground. It is possible to make the configuration easier to use when going out from across the liner plate 4. A modification of such a scaffolding apparatus 1 with a liner plate will be described with reference to FIGS. 4 and 5. However, the same components as those of the previous embodiment are denoted by the same reference numerals, and the description thereof is omitted.

Among the plurality of scaffolding apparatus 1 for installing a liner plate fixed to the liner plate 4, regarding the adjacent scaffolding apparatus 1 for installing a liner plate, the constituent members 9 and 11 may have the following functions. Good.
That is, as shown in FIGS. 4 and 5, for the component member 9, the pole 18 attached to the pole attaching portion 16 is extended downward until its lower end is close to the inclined surface 2, and each pole 18 Adjacent two liners by joining one or more (three in this embodiment) lifting scaffolds 39 constructed between the pair of poles to the lower part of the pole mounting portion 16 by welding or the like. You may make it form the ladder 40 extended below from the overhang | projection part 13 in the structural member 9 of the scaffold installation apparatus 1 with a plate.

  In addition, in order to form the ladder 40 described above, the liner plate-attached scaffold installation device 1 is separated from the one liner plate-attached scaffold installation device 1 with a gap substantially equal to or slightly larger than the width of the worker. In addition, it is additionally arranged without depending on the position of the connecting bolt hole of the liner plate 4 (that is, the component member 21 of the added scaffolding installation device 1 with the liner plate is attached to the liner plate only by the locking fixing portion 25. 4), the lower portion 18a of the pole 18 mounted on the pole mounting portion 16 of each of the liner plate mounting scaffold installation devices 1 is extended until it is close to the inclined surface 2, and the extended pole 18 The ladder 40 may be configured by laying an elevating scaffold 39 by welding or the like at a portion below the pole mounting portion 16.

  Further, with respect to the inner handrail pole 30 mounted on the pole mounting portion 28 of the component member 21, a short pole 42 having a dimension extending in a substantially horizontal direction via a rectangular parallelepiped block 41 on the upper end side of the pole 30. And a pole 44 having a short dimension extending substantially vertically downward is attached to the tip of the pole 42 via a rectangular parallelepiped block 43. Thereby, a pair of raising and lowering handrails 45 are provided at a predetermined interval on the component member 21 of the two adjacent liner plate attachment scaffold installation devices 1.

  By attaching the ladder 40 and the raising and lowering handrail 45 to the constituent members 9 and 21 in advance in an integrated manner, the two liner plate-attached scaffold installation devices 1 are attached to the liner plate 4, so that the liner plate 4 A ladder 40 and an elevating handrail 45 are provided at the same time as the scaffolding at the side of the wall.

  In the above-described configuration, the example in which the component member 9 and the ladder 40, the component member 21 and the raising / lowering handrail 45 are integrally provided is shown. Ascending / descending hands forming a pair constituted by detachably attaching the pole of the ladder 40 having a scaffold to the pole attaching portion 16 of the constituent member 9 making a pair or connecting the poles You may make it attach to the pole mounting part 28 of the structural member 21 which makes the pole of the slide 45 detachably afterwards.

  Further, a screw hole 46 as shown in FIG. 4 is provided in the locking piece 27 of the locking and fixing portion 25 of the component member 21 of the scaffolding device 1 for installing the liner plate. As shown in FIG. A ready-made safety step 50 may be fixed to the stopper piece 27 with a bolt 48 and a nut 49 so as to be arranged inside the liner plate 4. Thereby, raising and lowering of a worker becomes safer.

  In the above configuration, the case of applying to an arc-shaped (C-shaped) liner plate has been described. However, it goes without saying that it can be applied to a linear (S-shaped), J-shaped, and L-shaped liner plates. In the above-described configuration, the example in which the scaffold is formed on the side of the outer wall surface of the liner plate has been described. However, in order to form the scaffold on the side of the inner wall surface of the liner plate, the scaffold plate installation device 1 with the liner plate is used. May be.

6 and 7 show a second embodiment of the scaffolding installation 1 with liner plate according to the present invention.
As shown in FIG. 7, the scaffolding installation 1 with the liner plate is also configured by combining the structural member 9 and the structural member 21.

  Among these components, the component member 21 includes a locking and fixing portion 25 that locks and fixes to the flange 4a at the upper end portion of the liner plate 4, and a component member 9 that extends vertically and contacts the wall surface of the liner plate 4 and that will be described later. The position adjustment part 22 which can adjust the fixed position to the up-down direction, and the pole mounting part 28 which is provided in the vicinity of the locking fixing part 25 and can mount the pole are configured.

  More specifically, the component member 21 has a long plate 51 that extends vertically, and the position adjusting unit 22 has a pair of guide plates 52 that extend vertically on the long plate 51 at predetermined intervals by welding or the like. It is configured to stand in parallel. The pair of guide plates 52 are fixed at intervals slightly larger than the width of the base portion 10 of the constituent member 9 described later. Each guide plate 52 has a large number of through holes 53 in the vertical direction at a predetermined interval. It is drilled at. In this example, the pitch of the through-holes 53 is formed in the vertical direction with 18 pitches according to the thickness (for example, 34 mm) of the scaffolding plates 35 and 36.

  Further, the locking and fixing portion 25 is configured by a contact portion 25a formed by bending the upper end portion of the long plate 51 substantially at a right angle to the side opposite to the side on which the guide plate 52 is provided. As shown in FIG. 8 (a), a bolting through hole 26 is formed at the center of the contact portion 25 a, and the through hole 26 is connected to the flange 4 a of the liner plate 4. The bolts 5 are aligned with the bolt holes 5, the bolts 7 are inserted into the through holes 26, 5, and the nuts 8 are screwed into the bolts 7 and tightened to fix the structural member 21 to the flange 4 a at the upper end of the liner plate 4. I can do it.

  The pole mounting portion 28 is provided on the same side as the side on which the guide plate 52 is provided in the upper end portion of the long plate 51. This pole mounting portion 28 is obtained by fixing a pole mounting pipe 56 to a holding plate 55 welded or bolted to the long plate 51 by welding or the like, and the pole mounting pipe 56 has a pole inserted therein. A bolt 57 for fixing the pole is attached so as to be able to advance and retract. In addition, the holding plate 55 is provided with two dedicated holes 55a for attaching a string at two upper portions.

  On the other hand, the component member 9 extends vertically along the wall surface of the liner plate 4 and is detachably fixed to the position adjustment unit 22 of the component member 21, and below the substrate unit 10. A protruding portion 13 that is fixed and protrudes in a direction away from the liner plate 4 so that 35 and 36 can be placed thereon, and a pole mounting portion that is provided at the tip of the protruding portion 13 in the protruding direction and that can mount the pole 18 16.

  More specifically, the base portion 10 and the overhang portion 13 are made of square material, and the base portion 10 is accommodated between the pair of guide plates 52 so as to be slidable up and down, and is bolted to the upper side surface. The through hole 11 is formed so that the through hole 53 of the guide plate 52 aligned with the through hole 11 can be selected by sliding up and down between the guide plates 52. In this example, the through holes 11 of the base body portion 10 are formed at two locations, upper and lower, and are formed at a pitch twice the pitch of the through holes 53 of the guide plate 52.

  Therefore, the component member 9 can be adjusted up and down as long as the fixing position with respect to the component member 21 can align the through hole 11 of the base portion 10 with the through hole 53 of the guide plate 52, as shown in FIG. Fine adjustment can be made in 16 steps up and down in the range from the uppermost state shown to the lowermost state shown in FIG. 9B.

  Further, the overhanging portion 13 is fixed by welding a single frame material 59 via a reinforcing plate 58 so as to protrude substantially vertically from the lower end portion of the base portion 10 and is flattened upward. A long hole 61 penetrating in the vertical direction through which a fastener 60 for fixing the scaffold plates 35 and 36 is inserted is formed at three positions in the axial direction on the upper and lower surfaces.

  The pole mounting portion 16 is configured to be fixed by welding a pole mounting pipe 63 to the tip of the overhanging portion 13 via a reinforcing plate 62, and the pole mounting pipe 63 includes: A pole fixing bolt 64 for fixing the inserted pole is attached so as to be able to advance and retract.

Further, an adjustment bolt 65 for adjusting the inclination of the base portion 10, that is, the inclination of the overhang portion 13, is provided in the vicinity of the lower end portion of the base portion 10 facing the liner plate 4. As shown in FIG. 8B, the adjustment bolt 61 adjusts the amount of protrusion of the bolt head that comes into contact with the uneven surface of the liner plate 4 by adjusting the screwing amount. By adjusting the distance from the liner plate 4, the inclination of the overhanging portion 13 is adjusted in parallel.
In the above-described configuration, the same components as those in the above embodiment are denoted by the same reference numerals and the description thereof is omitted.

In the above configuration, in order to attach the liner plate-attached scaffold installation device 1 to the liner plate 4, the contact portion 25 a of the locking fixing portion 25 of the component member 21 is locked to the flange 4 a at the upper end of the liner plate 4, The screw hole 26 of the contact portion 25a is connected to the connecting bolt hole 5 of the flange 4a close to a desired position, the bolt 7 is inserted into the holes 26, 5 from the upper side, and the nut 8 is screwed and tightened. This prevents the component member 21 from inadvertently moving along the circumferential direction of the liner plate 4.
Thereafter, the base portion 10 of the constituent member 9 is accommodated between the guide plates 52 of the position adjusting portion 22 and is slid up and down to bolt the guide plate 52 and the base portion 10 at a desired position. Is fixed to the component member 21. After that, the screwing amount of the adjusting bolt 61 is adjusted so that the overhanging portion 13 is horizontal.

Such an operation is performed at each place where the liner plate-attached scaffold installation device 1 (component members 21 and 9) is attached. After that, the scaffold plates 35 and 36 are placed on the overhanging portion 13 and the scaffold plates 35. 36 is fixed by a fastener 60 attached through the elongated hole 61 of the overhanging portion 13. Then, if the poles of attached members (handrail poles, ladders, lifting handrails, etc.) provided with poles are attached to the pole mounting portions 28 and 16 according to the application, the assembly of the scaffold device is completed.
When it is necessary to install a handrail for preventing the fall, the handrail string-like member 38 is attached using the dedicated hole 55a formed in the holding plate 55 according to the height of the scaffold. May be. If the string-like member 38 is attached using such a dedicated hole 55a, it is not necessary to attach the pole 30 to the pole mounting portion 28 and pass the string-like member 38 through the through hole 31. Installation is easy.

  Therefore, when such a scaffolding apparatus 1 with a liner plate is used, even when a scaffold is formed outside the liner plate 4 of the temporary structure 3 as shown in FIG. In the case where the scaffold is formed on the inner side of the liner plate 4, the component member 21 is bolted by locking the contact portion 25 a of the locking fixing portion 25 at an appropriate position of the flange 4 a at the upper end of the liner plate 4, Thereafter, the structural member 9 is fixed to the structural member 21 by adjusting the position in the vertical direction, and the same work is performed to secure the scaffold plates 35 and 36 to the scaffold installation surface 59a of the overhanging portion 13 of the adjacent structural member 9. For example, since a scaffold can be formed, the same member can be shared when the scaffold is installed inside and outside the liner plate 4.

  Further, according to the above-described scaffold installation device with liner plate 1, the through holes 53 are formed in the position adjusting unit 22 at a pitch equal to the thickness of the scaffold plate, so as shown in FIG. , 36 can be fixed by superimposing the height of the component 9 so that the scaffolding plates 35, 36 are horizontal.

  Furthermore, according to the above-described scaffold installation device 1 with a liner plate, the overhanging portion is configured only by the frame material 59 extending in the horizontal direction, and the subframe that holds the frame material 59 as in the first embodiment. Therefore, there is no inconvenience that the subframe interferes with a fixed object or the like at the installation location, and the scaffold installation device cannot be installed, and the restriction on the installation location can be relaxed. Further, since there is no subframe, the weight of the component member 9 can be reduced, and the scaffold installation device can be reduced in weight. Furthermore, since there is no sub-frame, it is possible to ensure a large adjustment range for the upper and lower components 9.

  Furthermore, since the adjustment bolt 65 for adjusting the inclination of the overhanging portion 13 is provided at the lower portion of the base portion 10, the pitch of the unevenness of the liner plate 4 and the pitch of the through holes 53 of the position adjusting portion 22 are different. However, the overhanging portion 13 can be adjusted horizontally.

  In this example as well, even if the poles 30 and 18 having the through holes 31 and 19 through which the string-like members are passed are attached to the pole mounting portions 28 and 16, the pair as shown in FIG. Even if the pole of the ladder 40 having the poles formed and the raising and lowering scaffolds erected between the poles is detachably mounted, the lifting and lowering that forms a pair constituted by connecting the poles is also possible. You may make it mount the pole of the handrail 45 so that attachment or detachment is possible.
