Description

The present invention relates to a support structure for scaffolding/curing units.

The scaffolding/protection unit described in Patent Document 1 comprises a frame (scaffolding) that can slide up and down, and a bracket for fixing this frame to a structure.
The bracket is provided with a guide portion that guides the guide rail of the frame so that it can slide up and down, and a clamp that fixes the guide rail, at separate locations.

Patent No. 4058383

In the scaffolding/protection unit of Patent Document 1, when sliding the frame up and down, it is first necessary to spread the clamps apart and then remove the clamps so that they do not interfere with the frame.
Furthermore, when the frame is slid up and down, the clamp must be moved to a position where it does not interfere with the guide rail.

As such, the scaffolding/covering unit of Patent Document 1 requires multiple, time-consuming steps to slide the fixed frame, leaving room for improvement in terms of workability.

In view of the above, the present invention aims to provide a support structure for scaffolding/covering units that improves workability during sliding.

The support structure for the scaffolding/curing unit described in claim 1 comprises a scaffolding/curing unit that is slidably arranged along the outer surface of a structure, a guide rail that is provided on the scaffolding/curing unit and extends in the vertical direction, and a holder portion that is attached to the structure and can select between a first state in which the guide rail is slidably guided and a second state in which the guide rail is fixed , wherein the holder portion is provided with an adjustment portion that adjusts the clearance with the guide rail when the guide rail slides, and is also provided with a pair of arms that form the clearance between the guide rails, and a support plate that is fixed to the structure and to which the arms are attached, and the adjustment portion comprises a long hole provided in the support plate or the arm, and a screw member that is provided in the arm or the support plate and can be slidably inserted into the long hole and fixed .

The holder section, which serves both the guiding and fixing functions for the guide rail provided on the scaffolding/curing unit, can select between a first state in which it slidably guides the guide rail, and a second state in which it fixes the guide rail. In the first state, the holder section slidably guides the guide rail, allowing the scaffolding/curing unit to slide up and down. In the second state, the holder section fixes the guide rail, allowing the scaffolding/curing unit to be fixed to the structure via the holder section.

According to the support structure for the scaffolding/curing unit described in claim 1, the guide function and fixing function of the guide rail are integrated, thereby improving the ease of construction of the scaffolding/curing unit and the workability when sliding the scaffolding/curing unit compared to when the component for fixing the guide rail and the component for guiding the guide rail are provided in separate locations.
The adjustment section adjusts the clearance between the holder section and the guide rail, maintains the adjusted clearance, and sets an optimal clearance, allowing the guide rail to slide smoothly while being guided.
In addition, the clearance between the holder part and the guide rail is adjusted to zero. By bringing the holder part into contact with the guide rail and applying pressure, the guide rail can be securely fixed.
In addition, in the support structure for the scaffolding/curing unit described in claim 1, the clearance can be adjusted by sliding the screw member inside the long hole.

The invention described in claim 2 is a support structure for scaffolding/curing units described in claim 1 , in which a plurality of the scaffolding/curing units whose surfaces are covered with curing sheets are arranged along the width direction of the outer surface of the structure, and curing net holding members which expand and contract horizontally toward adjacent scaffolding/curing units are provided on the upper and lower sides of the width direction of the scaffolding/curing units, and a locking portion for locking the curing sheet is provided at the tip of the curing net holding member in the expansion and contraction direction.

When multiple scaffolding/curing units with their surfaces covered in curing sheets are arranged along the width of the outer surface of a structure, gaps may be formed between the scaffolding/curing units that are not covered by the curing sheet.
When covering this gap with a curing sheet, the scaffolding/curing unit is covered with a curing sheet whose width dimension is greater than the width of the scaffolding/curing unit, and a part of the curing sheet in the width direction is made to protrude so as to cover the gap between the scaffolding/curing unit and the adjacent scaffolding/curing unit. Then, the curing net holding member is extended to reach the other adjacent scaffolding/curing unit, and the end of the protruding curing sheet is engaged with the engagement part at the tip. In this way, the gap between the scaffolding/curing unit and the scaffolding/curing unit can be covered with the curing sheet protruding from the scaffolding/curing unit, and the protruding curing sheet can be fixed in place. Therefore, the outer surface of the structure can be covered with the curing sheet so that there are no gaps.

As described above, the present invention has the excellent effect of providing a support structure for scaffolding/curing units that improves workability during sliding.

FIG.

[First embodiment]
A first embodiment of a support structure for a scaffolding/curing unit according to the present invention will be described with reference to Figures 1 to 15. In the figures, the arrow Z direction indicates the up-down direction, the arrow X direction indicates the width direction (horizontal direction) of the scaffolding/curing unit, and the arrow Y direction indicates the direction perpendicular to the up-down direction and the width direction of the scaffolding/curing unit (the front-back direction of the scaffolding/curing unit; horizontal direction).
1 and 4, the support structure for the scaffolding/curing unit of this embodiment is roughly divided into a scaffolding/curing unit 10 that slides in the vertical direction, and a scaffolding/curing unit fixing device 12 as a holder part that is attached to a structure such as a building and can be selected (switched) between a first state in which the scaffolding/curing unit 10 is guided to be slidable up and down, and a second state in which the scaffolding/curing unit 10 is fixed so that it cannot slide. Details of the first and second states will be described later.

As shown in Figures 1(B) and 2(B), the scaffolding/curing unit 10 of this embodiment includes a frame 14 that is rectangular in front view. The frame 14 of this embodiment is composed of two small frames 14A that are narrow and elongated in the vertical direction, and two small frames 14B that are connected in the width direction. In the frame 14, the small frames 14B are arranged on both sides in the width direction, and the small frame 14A is arranged inside the small frames 14B on both sides.
As an example, the small frame 14A is composed of a pair of vertical members 16a made of square steel pipes with a rectangular cross section extending in the vertical direction and spaced apart in the horizontal direction, inner baseboards 18 made of a plurality of steel pipes extending in the horizontal direction and spaced apart in the vertical direction and suspended between the vertical members 16a, handrails 20 made of steel pipes arranged between the inner baseboards 18, and braces 22 made of steel material arranged diagonally.
On the other hand, the small frame 14B, as an example, is composed of vertical members 16a and 16b made of square steel pipes with a rectangular cross section extending in the vertical direction and spaced apart in the horizontal direction, inner baseboards 18 made of a plurality of steel pipes extending in the horizontal direction and spaced apart in the vertical direction and spanning between the vertical members 16a and 16b, handrails 20 made of steel pipes arranged between the inner baseboards 18, and braces 22 made of steel material arranged diagonally.

In addition, the frame 14 used in the scaffolding/curing unit 10 of this embodiment is not limited to the above-mentioned structure in which multiple small frames 14A and small frames 14B are connected together, but may have a generally known structure.
3, a similarly structured frame 14 may be placed outside the frame 14 of the scaffolding/curing unit 10 with a gap therebetween, the frame 14 on the building side and the outer frame 14 may be connected with joists 15, and floorboards 17 that enable workers to walk and work may be mounted on the joists 15. This allows workers to easily move laterally and work on the scaffolding/curing unit 10.

The frame 14 is supported by the scaffolding/curing unit fixing device 12 and can be positioned along the exterior of the building 8 (see Figure 15) and along an extension of the exterior of the building (above the top of the building).

1, 4 and 5, a guide rail 24 is disposed along the vertical members 16a and 16b on the building side of the frame 14. The guide rail 24 in this embodiment is formed of a round steel pipe, for example.
Next, the connection structure of the guide rail 24 will be described.
Fig. 5 shows a connection between one small frame 14A (left side in Fig. 1) and the other small frame 14A adjacent thereto (right side in Fig. 1). As shown in Fig. 5, one vertical member 16a of one small frame 14A and the guide rail 24 are connected by a connecting member 28 made of a steel plate. The connecting members 28 are provided at intervals in the longitudinal direction of the vertical member 16a (see Fig. 1(A)), and are fixed to the vertical member 16a and the guide rail 24 by welding or the like.
A connecting member 26 made of a steel plate arranged parallel to a connecting member 28 is joined by welding to the vertical member 16a of the other small frame 14A.

The connecting members 28 of one small frame 14A and the connecting members 26 of the other small frame 14A are fixed to each other using connecting bolts 30 and nuts 32 that pass through them while overlapping each other, thereby connecting one small frame 14A to the other small frame 14A. Although not shown in the figure, the small frames 14B on both sides and the inner small frame 14A are also fixed to each other in the same manner. The width of the frame 14 can be changed by increasing or decreasing the number of small frames 14A.

Although not shown in the figure, guide rails 24 are attached to the vertical members 16b of the small frames 14B on both sides via connecting members 28.

As shown in FIG. 1, a sling plate 34 is fixed to the top of each of the two vertical members 16a of the frame 14. The sling plate 34 has a hole (not shown) for inserting a sling wire rope (not shown) or the like.

(Scaffolding/Curbing unit fixing device)
As shown in Figures 4 and 7, the scaffolding/covering unit fixing device 12 broadly comprises an L-shaped bracket A36 that is attached to the rising portion 42 of the balcony of the building, and an L-shaped bracket B38 that is supported by the L-shaped bracket A36.

(L-shaped bracket A)
As shown in FIG. 7, the L-shaped bracket A36 includes an L-shaped plate 40 made of a steel plate or the like and having an L-shape in side view.

As shown in Figures 4 and 7, the L-shaped plate 40 has a horizontal portion 40A that is placed on the upper part of the rising portion 42 of a structure, for example, a balcony of a building, and a vertical portion 40B that is placed along the outer surface of the rising portion 42, and is formed into a roughly L-shape when viewed from the side.

A rectangular mounting plate 44 that comes into surface contact with the upper part of the rising part 42 is fixed to the lower end of the horizontal part 40A by welding or the like. A rubber sheet 45 is attached to the lower surface of the mounting plate 44 in the area that comes into contact with the upper part of the rising part 42.

As shown in Figures 6 and 7, a rectangular holding plate 46 that is in surface contact with the outer surface of the rising portion 42 is fixed to the end of the vertical portion 40B on the rising portion 42 side by welding or the like. A rubber sheet 48 is attached to the holding plate 46 at the portion that comes into contact with the outer surface of the rising portion 42.

As shown in Figures 4 and 7, the L-shaped bracket A36 is fixed to the balcony rising part 42 when in use. As an example, the L-shaped bracket A36 can be fixed to the balcony rising part 42 by screwing the threaded part of the anchor bolt 52, which is inserted through the long hole 50 formed in the mounting plate 44, into the top of the balcony rising part 42.

The long holes 50 formed in the mounting plate 44 are formed long in the longitudinal direction of the balcony riser 42 (horizontal direction of the building), and by loosening the anchor bolts 52, the L-shaped bracket A36 can fine-tune the longitudinal position of the balcony riser 42.

In this embodiment, the L-shaped bracket A36 is fixed to the balcony rising portion 42 using an anchor bolt 52, but the L-shaped bracket A36 may be fixed to the balcony rising portion 42 using other methods.

As shown in Figures 4 and 7, the L-shaped bracket A36 has multiple long holes 54 formed in the horizontal portion 40A of the L-shaped plate 40. The long holes 54 are formed long in the horizontal direction, and a fixing bolt 60 (described later) is inserted through them.

(L-shaped bracket B)
The L-shaped bracket B38 includes an L-shaped plate 56 made of a steel plate or the like and having an L-shape in side view.

As shown in FIG. 7, the L-shaped plate 56 has a horizontal portion 56A that is arranged along the horizontal portion 40A of the L-shaped plate 40 in the L-shaped bracket A36, and a vertical portion 56B that is arranged above the vertical portion 40B of the L-shaped bracket A36 and extends upward, and is formed in a roughly L-shape when viewed from the side.

As shown in FIG. 4, a round hole 58 is formed in the horizontal portion 56A of the L-shaped plate 56 at a position opposite the long hole 54 formed in the horizontal portion 40A of the L-shaped bracket A36. The male thread of a bolt 60 is inserted into the long hole 54 and the round hole 58, and the horizontal portion 40A of the L-shaped bracket A36 and the horizontal portion 56A of the L-shaped bracket B38 are clamped between the head 60A of the bolt 60 and a nut 62 screwed onto the male thread, thereby attaching the L-shaped bracket B38 to the L-shaped bracket A36.

As shown in Figures 4 and 7, the male thread of the bolt 60 that has been inserted through the round hole 58 is inserted into the long hole 54, so that the L-shaped bracket B38 can slide horizontally relative to the L-shaped bracket A36 in the direction toward and away from the exterior surface of the building (the balcony rising portion 42) (the direction of arrow A in Figures 4 and 7).

A fixed/guide member mounting plate 64, which is made of a rectangular steel plate or the like and acts as a support plate arranged vertically and in the up-down direction relative to the vertical portion 56B, is fixed to the L-shaped plate 56 by welding or the like at the side end of the vertical portion 56B facing the frame.

(Scaffolding/Curbing unit fixing device)
6 and 7, the fixed/guide member attachment plate 64 is provided with a fixed/guide portion 66 as a holder portion on the frame side. The fixed/guide portion 66 is configured to include a fixed/guide member B 68 and a fixed/guide member A 70.

(Fixed/Guide Member B)
4, 6, 7 and 8, the fixed/guide member B68 has a rectangular base plate 72 made of a steel plate or the like and arranged along the fixed/guide member mounting plate 64. A vertical member 74 made of a steel plate or the like, curved in side view and erected perpendicular to the base plate 72 is fixed by welding or the like to the center of the longitudinal direction of the base plate 72. On both sides in the thickness direction of the vertical member 74, fan-shaped reinforcing plates 76 are arranged which are fixed to the base plate 72 and the vertical member 74 by welding or the like.

As shown in FIG. 8, a pair of bearing plates 78 made of steel plates or the like are fixed by welding or the like to the upper portion of the vertical member 74 (the portion opposite the base plate 72) so as to sandwich the vertical member 74 from both sides.

The base 82 of the bolt 80 for fixing the scaffolding/curing unit is placed between the pair of bearing plates 78. The base 82 is formed in a cylindrical shape, and a shaft 84 that is arranged to span between one bearing plate 78 and the other bearing plate 78 is inserted into a hole in the base 82.

A steel male screw 86 extending perpendicular to the shaft 84 is fixed to the outer periphery of the base 82 by welding or the like. The shaft 84 is fixed to the bearing plate 78, and the base 82 is rotatable relative to the shaft 84. Therefore, the scaffolding/curing unit fixing bolt 80 is rotatable around the shaft 84. A nut 88 is screwed onto the male screw 86.

The base plate 72 has round holes 90 formed on both sides of the vertical member 74, through which the male threads of the fixing/guide member mounting bolts 106, which serve as screw members described below, are inserted.

(Fixed/Guide Member A)
9, the fixed/guide member A70 includes a rectangular base plate 92 made of a steel plate or the like and disposed along the fixed/guide member mounting plate 64. A vertical member 94 made of a steel plate or the like and curved in side view and erected perpendicular to the base plate 92 is fixed by welding or the like to the center of the longitudinal direction of the base plate 92. Note that on both sides in the thickness direction of the vertical member 94, fan-shaped reinforcing plates 96 are disposed which are fixed to the base plate 92 and the vertical member 94 by welding or the like.

A nut support part 98 made of a steel plate or the like and formed into a semi-box shape is fixed by welding or the like to the upper part of the vertical member 94 (the part opposite the base plate 92). A groove 100 is formed in the vertical wall 98A of the nut support part 98 into which the male screw 86 of the scaffolding/curing unit fixing bolt 80 can be inserted.

As shown in Figures 6 and 9, the base plate 92 of the L-shaped bracket B38 has round holes 102 formed on both sides of the vertical member 94, through which the male threads of the fixing/guide member mounting bolts 106, which serve as screw members described below, are inserted.

As shown in FIG. 6, the fixing/guide member mounting plate 64 of the L-shaped bracket B38 has multiple long holes 104 that are long in the horizontal direction and spaced at regular intervals in the vertical direction on both sides of the L-shaped plate 56.

As shown in FIG. 6, in this embodiment, the fixed/guide member B68 is disposed on the right side of the plate 64 for mounting the fixed/guide member, and the fixed/guide member A70 is disposed on the left side of the plate 64 for mounting the fixed/guide member, but the fixed/guide member B68 may be disposed on the left side of the plate 64 for mounting the fixed/guide member, and the fixed/guide member A70 may be disposed on the right side of the plate 64 for mounting the fixed/guide member.

(Method of Sliding and Fixing the Fixing/Guide Member B)
As shown in Figures 4 and 6, the male threaded portion of a fixing/guide member mounting bolt 106 serving as a screw member is inserted into the long hole 104 of the fixing/guide member mounting plate 64, and the male threaded portion is passed through the long hole 104 and the round hole 90 formed in the base plate 72 of the fixing/guide member B68. The fixed/guide member B68 can be fixed to the fixed/guide member mounting plate 64 by sandwiching the base plate 72 and the fixed/guide member mounting plate 64 between a nut 108 screwed into the male threaded portion and a head 106A of the fixing/guide member mounting bolt 106.

In addition, by loosening the nut 108 screwed into the male thread of the fixing/guide member mounting bolt 106, the fixing/guide member B68 can be slid along the longitudinal direction of the long hole 104 (the direction in which it moves toward and away from the guide rail 24).

(Method of Sliding and Fixing the Fixing/Guide Member A)
The male threaded portion of the fixing/guide member mounting bolt 106 is inserted into the long hole 104 of the fixing/guide member mounting plate 64, and passed through the long hole 104 and the round hole 102 formed in the base plate 92 of the fixing/guide member A70. The fixed/guide member A70 can be fixed to the fixed/guide member mounting plate 64 by sandwiching the base plate 92 and the fixed/guide member mounting plate 64 between the nut 108 screwed into the male threaded portion and the head 106A of the fixing/guide member mounting bolt 106.

In addition, by loosening the nut 108 screwed into the male screw portion, the fixing/guide member A70 can be slid along the longitudinal direction of the long hole 104 (the direction in which it approaches and moves away from the guide rail).

As shown in FIG. 4, the fixed/guide section 66 is configured so that the aforementioned guide rail 24 can be positioned between the curved recess 74A of the vertical member 74 of the fixed/guide member B 68 and the curved recess 94A of the vertical member 94 of the fixed/guide member A 70.

When the fixed/guide member B68 and the fixed/guide member A70 are brought close to each other and the guide rail 24 is clamped between the recess 74A of the fixed/guide member B68 and the curved recess 94A of the fixed/guide member A70, the guide rail 24 is surrounded by the recess 74A of the fixed/guide member B68, the curved recess 94A of the fixed/guide member A70, and the flat fixed/guide member mounting plate 64, thereby fixing the guide rail 24.

(Installation structure of protective net)
1(B) and 2(B), the scaffolding/cure unit 10 has a protective net 110 stretched around the outside of the frame 14 to prevent falls or tripping. The protective net 110 is large enough to cover at least the entire front of the frame 14. The protective net 110 in this embodiment is formed so that its width is wider than the width of the frame 14, and in this embodiment, the protective net 110 is attached so that a portion of the left side of the frame 14 when viewed from the front protrudes outward in a strip shape beyond the left end of the frame 14.

(Curing net holding member)
As shown in FIG. 1B , protective net holding members 112 for holding the ends of protective nets 110 are provided at the upper and lower ends of the frame 14 on the left side of the drawing.

Figure 10 shows a protective net holding member 112 provided on the underside of the frame 14. As shown in Figure 10, the protective net holding member 112 is configured with a guide plate 114 and a slide arm 116 that is slidably arranged inside the guide plate 114.

The guide plate 114 is arranged horizontally and fixed to the vertical member 16b by welding, screwing, etc.

The guide plate 114 is provided with a slide arm support 118 having a generally U-shaped cross section as shown in Figures 11(A) and 11(B). One side wall 118A of the slide arm support 118 has a hole (not shown) that penetrates from the inside to the outside, and a nut 120 is fixed by welding or the like to the portion of the side wall 118A where the hole is formed.

The male thread of the bolt 122 is screwed into the nut 120 from the outside. The male thread of the bolt 122 passes through the nut 120 and a hole formed in the side wall 118A and can protrude to the inside of the slide arm support 118.

As shown in Figure 10, one longitudinal end of the slide arm support 118 is covered with a box-shaped end lid 124 as shown in Figures 11(C) and (D). A hole (not shown) that penetrates from the inside to the outside is formed in the side of the end lid 124, and a nut 126 is fixed to the part where the hole is formed by welding or the like.

The end cover 124 is fixed to the slide arm support 118 by screwing and tightening a screw portion (not shown) that passes through a hole 127 formed in the slide arm support 118 into a nut 126 of the end cover 124 that is placed on one longitudinal end of the slide arm support 118.

As shown in Figures 12(A) and (B), the slide arm 116 is constructed by connecting a pair of steel materials (such as flat steel bars, for example) 128 arranged parallel to each other with width-determining plates 132, 134. A fixed gap is provided between one steel material 128 of the slide arm 116 and the other steel material 128.

At one end of the slide arm 116, between one steel material 128 and the other steel material 128, there is a hook plate 138 with a hole 138A formed therein for attaching a rope 136 (see FIG. 10) that is attached to the end of the protective net 110.

A shaft 140 that passes through the pair of steel members 128 and the hook plate 138 is fixed to the pair of steel members 128, and the hook plate 138 can rotate around the shaft 140 (in the direction of arrow B in Figure 12 (A)).

In addition, bearings 142, 144 are arranged between one steel material 128 and the other steel material 128 on the other end side of the slide arm 116. The bearings 142, 144 are rotatably supported by a shaft 146 that passes through the pair of steel materials 128 and is fixed to the pair of steel materials 128.

One bearing 142 rotates in contact with the inner surface of side wall 118A of guide plate 114, and the other bearing 144 rotates in contact with the inner surface of side wall 118B opposite side wall 118A of guide plate 114, allowing slide arm 116 to slide smoothly along the longitudinal direction inside guide plate 114.

A rectangular stopper plate 148 is fixed to the outer surface of one of the steel members 128 of the slide arm 116, near the bearing 142. On the other hand, a stopper stopper 150 that abuts against the stopper plate 148 is attached to the end of the guide plate 114 opposite the end to which the end cover 124 is attached.

In the protective net holding member 112 of this embodiment, the stopper plate 148 of the slide arm 116 abuts against the stopper stopper 150 of the guide plate 114, preventing the slide arm 116 arranged inside the guide plate 114 from slipping out of the guide plate 114.

In addition, by tightening the bolt 122 screwed into the nut 120 of the guide plate 114 and abutting the tip of the bolt 122 against the side end surface of the slide arm 116 (steel material 128), the slide arm 116 can be fixed to the slide arm 116 so that the slide arm 116 does not slide.

Figure 13 shows a protective net holding member 112 provided on the upper side of the frame 14. As shown in Figure 13, the protective net holding member 112 provided on the upper side of the frame 14 has a vertically symmetrical shape with respect to the protective net holding member 112 provided on the lower side shown in Figure 10.

(Action, Effect)
Next, the procedures for fixing the scaffolding/curing unit 10 of this embodiment and sliding it upward will be described below.

(1) First, the scaffolding/curing unit fixing device 12, to which the scaffolding/curing unit 10 has already been attached, is fixed to the rising part 42 of the balcony of the building using anchor bolts 52 (see Figure 7). It is also possible to first fix the scaffolding/curing unit fixing device 12 to the rising part 42 of the balcony, and then attach the scaffolding/curing unit 10 to the scaffolding/curing unit fixing device 12. Here, as shown in Figure 14 (A), the guide rail 24 is fixed by being clamped between the fixing/guide member B 68 and the fixing/guide member A 70.

(2) As shown in FIG. 14(B), loosen the nut 88 that is screwed onto the scaffolding/curing unit fixing bolt 80 of the fixing/guide member A70, and move the nut 88 away from the vertical wall 98A of the nut support portion 98 of the fixing/guide member A68.

(3) As shown in Figure 14 (C), rotate the scaffolding/curing unit fixing bolt 80 in the direction of arrow C, and move the scaffolding/curing unit fixing bolt 80 away from the fixing/guide member B68 as shown in Figure 14 (D).

(4) Loosen the nut 108 screwed onto the fixed/guide member mounting bolt 106, and slide the fixed/guide member B68 and the fixed/guide member A70 in the direction away from each other (in the direction of arrow D) as shown in FIG. 14(E), to move the fixed/guide member B68 and the fixed/guide member A70 away from the guide rail 24.

At this time, the fixed/guide member B68 and the fixed/guide member A70 are slid so that the distance T between the tip of the fixed/guide member B68 and the tip of the fixed/guide member A70 is not larger than the diameter D of the guide rail 24, and a slight gap is provided between the fixed/guide member B68 and the guide rail 24, and between the fixed/guide member A70 and the guide rail 24. The slight gap referred to here is a gap that allows the guide rail 24 to slide smoothly between the fixed/guide member B68 and the fixed/guide member A70, and there is no particular restriction on the actual dimensions.

(5) Next, the nuts 108 that are threaded onto the fixing/guide member mounting bolts 106 are tightened to fix the fixing/guide member B 68 and the fixing/guide member A 70 to the fixing/guide member mounting plate 64 .
As described above, fixed/guide member B 68 and fixed/guide member A 70 are fixed to the fixed/guide member mounting plate 64 while spaced away from the guide rail 24, and as shown in Figure 14 (E), the scaffolding/curing unit fixing bolt 80 is rotated so that it is not positioned in the vertical direction of the guide rail side connecting member 28 that supports the guide rail 24, and is moved away from the sliding path (vertical direction) of the vertical member side connecting member 26 and the guide rail side connecting member 28, and the scaffolding/curing unit 10 is prepared for sliding (the first state of the present invention).

(6) After the scaffolding/curing unit 10 has been prepared for sliding in the manner described above, the scaffolding/curing unit 10 can be hoisted using a crane or the like and slid upwards.
When the scaffolding/curing unit 10 slides, the guide rail 24 is surrounded by the fixed/guide member B 68, the fixed/guide member A 70, and the fixed/guide member mounting plate 64 and is held in a freely slidable manner, so that the guide rail 24 can slide smoothly while being guided by the scaffolding/curing unit fixing device 12 without coming off the scaffolding/curing unit fixing device 12.

(7) The scaffolding/curing unit 10 can be slid upward by engaging a slinging wire rope (not shown) with the slinging plate 34 of the scaffolding/curing unit 10 and hoisting the slinging wire rope by hooking it onto a hook of a crane or the like.

(Fixing scaffolding/curing units)
Next, the procedure for fixing the scaffolding/curing unit 10 will be described.
(8) Loosen the nuts 108 that are threaded onto the fixed/guide member mounting bolts 106 that secure the fixed/guide member B 68 and the fixed/guide member A 70, and bring the fixed/guide member B 68 and the fixed/guide member A 70 closer to each other and into contact with the guide rail 24.

(9) The scaffolding/curing unit fixing bolt 80 is rotated and inserted into the groove 100 provided in the nut support part 98, and the nut 88 is rotated and pressed against the vertical wall 98A of the nut support part 98. This causes the guide rail 24 to be tightly clamped between the fixed/guide member B 68 and the fixed/guide member A 70.

(10) After the guide rail 24 is clamped between the fixed/guide member B 68 and the fixed/guide member A 70, the nuts 108 threaded onto the fixed/guide member mounting bolts 106 are tightened to fix the fixed/guide member B 68 and the fixed/guide member A 70 to the fixed/guide member mounting plate 64.
This ensures that the scaffolding/covering unit 10 after sliding is fixed with the guide rail 24 at the fixing/guide section 66.

Thus, according to the support structure for the scaffolding/curing unit of this embodiment, the scaffolding/curing unit fixing device 12 has both a guide function for slidably guiding the guide rail 24 of the scaffolding/curing unit 10, and a fixing function. Therefore, the scaffolding/curing unit fixing device 12 can easily switch between a first state in which the guide rail 24 of the scaffolding/curing unit fixing device 12 is slidably guided, and a second state in which the guide rail 24 is fixed (clamped).

In addition, since one scaffolding/curing unit fixing device 12 has both a guide function for slidably guiding the guide rail 24 of the scaffolding/curing unit 10 and a fixing function, the number of parts can be reduced and the configuration simplified compared to when the guide section with the guide function and the fixing section with the fixing function are provided in separate locations.

As described above, when sliding the guide rail 24, the fixed/guide section 66 having a clamping function, which is composed of the fixed/guide member B68 and the fixed/guide member A70, does not need to be removed from the fixed/guide member mounting plate 64, and it is sufficient to simply slide the fixed/guide member B68 and the fixed/guide member A70 on the fixed/guide member mounting plate 64. This improves workability compared to when the fixed/guide section 66 is removed, and also improves workability when constructing the scaffolding/curing unit 10.

The above describes the upward sliding of the scaffolding/curing unit 10, but the same procedure can also be followed to slide the scaffolding/curing unit 10 downward with ease.

(How to install the protective net)
Next, the installation of the protective net 110 will be described.
After the scaffolding/cure unit 10 is installed, a protective net 110 is stretched so as to cover the outer surface of the frame 14. The protective net 110 may be fixed to the frame 14 at appropriate locations using ropes or the like (not shown) as in the conventional manner.

According to the support structure of the scaffolding/curing unit of this embodiment, when multiple scaffolding/curing units 10 are arranged on the outside of a building with horizontal gaps S therebetween, as shown in FIG. 10, for example, a curing net 110 can be stretched to hide the gaps S between the scaffolding/curing units 10. Note that in FIG. 10, the curing net 110 of the scaffolding/curing unit 10 on the right side of the drawing is shown by a two-dot chain line, and the curing net 110 of the scaffolding/curing unit 10 on the left side of the drawing is shown by a one-dot chain line.

The frame 14 of the scaffolding/curing unit 10 is entirely covered with a curing net 110 that is wider than the frame 14, and the strip-shaped portion that extends beyond the side of the frame 14 (here, the left side) is placed in the gap S between the two scaffolding/curing units 10.

Then, as shown in FIG. 3, the slide arm 116 is pulled out from the protective net holding members 112 provided on the upper and lower parts of the frame 14 so as to cross the gap S, and as shown in FIG. 10, the tip of the slide arm 116 is placed on the front side of the vertical member 16b of the adjacent scaffolding/protection unit 10, and the bolt 122 of the guide plate 114 is tightened to fix the slide arm 116 to the guide plate 114.

Then, the hook plate 138 at the tip of the slide arm 116 is connected to the rope 136 attached to the end of the protective net 110, and the protective net 110 that has filled the gap S is fixed in place.

As shown in FIG. 10, it is preferable that the protective net 110 of the scaffolding/curing unit 10 on the right side of the drawing and the protective net 110 of the scaffolding/curing unit 10 on the left side of the drawing are partially overlapped.

In addition, after connecting the hook plate 138 to the rope 136 attached to the protective net 110, the slide arm 116 may be pulled out to close the gap S between the units.

This allows the outer surface of each scaffolding/curing unit 10 and the gaps S between adjacent scaffolding/curing units 10 in the horizontal direction to be covered and sealed with the curing net 110.

Figure 15 shows an outline of an example of a building 8 under construction with a scaffolding/curing unit 10 in a perspective view. The dashed two-dot line shows the scaffolding/curing unit 10 before sliding, and the solid line shows the scaffolding/curing unit 10 after sliding.

The scaffolding/curing unit 10 can be installed not only when constructing a building, but also when demolishing a building. For example, when demolishing a building from above, the scaffolding/curing unit 10 can be fixed to the top of the building, and the scaffolding/curing unit 10 can be slid downward as the demolition of the building progresses. The scaffolding/curing unit 10 can also be installed, for example, when renovating the exterior of a building, and can be used for a variety of purposes related to buildings.

[Other embodiments]
Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and it goes without saying that the present invention can be implemented in various modified forms without departing from the spirit and scope of the present invention.

In the above embodiment, an example was described in which the scaffolding/curing unit 10 was slid up and down, but if the exterior surface of the building is inclined relative to the vertical direction, the scaffolding/curing unit 10 may be slid along the inclined exterior surface of the building.

The scaffolding/covering unit 10 is set up to face the exterior of the building, but may also be slid into position so that a portion of it protrudes above the top of the building.

In the above embodiment, the L-shaped bracket A36 is attached to the rising part 42 of the balcony of the building, but the L-shaped bracket A36 may be attached to a part of the balcony other than the rising part 42. In this case, the shape of the L-shaped bracket A36 can be appropriately changed to match the shape of the part to which it is attached.

In the above embodiment, the fixed/guide member B68 and the fixed/guide member A70 are slid along the longitudinal direction of the long hole 104 by inserting the fixed/guide member mounting bolt 106 into the long hole 104 provided in the fixed/guide member mounting plate 64, but the present invention is not limited to this. It is also possible to provide a long hole 104 on the side of the fixed/guide member B68 and the fixed/guide member A70 and insert the fixed/guide member mounting bolt 106 into the long hole 104, thereby allowing the fixed/guide member B68 and the fixed/guide member A70 to slide along the longitudinal direction of the long hole 104.

The shape of the long hole 104 is not limited to the shape shown in FIG. 5, and may be the shape shown in FIG. 16, for example. The long hole 104 shown in FIG. 16 has a protrusion 104A formed in the middle of the long hole 104 in the longitudinal direction, into which the male screw of the fixing/guide member mounting bolt 106 fits. The distance L between the protrusion 104A of one long hole 104 and the protrusion 104A of the other long hole 104 is set to an optimal dimension for fastening the guide rail 24 between the fixing/guide member B68 and the fixing/guide member A70. Therefore, when fastening the guide rail 24 between the fixing/guide member B68 and the fixing/guide member A70, the guide rail 24 can be reliably fastened by fastening the male screw of the fixing/guide member mounting bolt 106 with the protrusion 104A fitted in.
