  Hereinafter, the best mode of the present invention will be described based on examples.

A first embodiment of the present invention will be described with reference to FIGS. 2 is a perspective view showing a use state of the unloading assisting tool embodying the unloading method according to the present invention, FIG. 3 is an external perspective view of the unloading assisting tool in FIG. 2, and FIG. 4 is a retainer in FIG. FIG. 5 is an explanatory diagram of a method for vertically connecting building frame members, FIG. 6 is an explanatory diagram of the moment exerted by the unloading aid on the building frame member, and FIG. 7 is a diagram. It is a perspective view which shows the use condition of the retaining metal fitting in 2. FIG. In these drawings, the same components as those in FIG. 1 are denoted by the same reference numerals.
In FIG. 2, reference numeral 1 denotes a bite-type temporary scaffold in the middle of dismantling. A building frame member 2 is erected on the uppermost stage, and the entire steel frame is placed on the front vertical frame 8 of the building frame member 2. A product unloading assisting tool 40 is detachably mounted. The worker A on the uppermost stage hangs the unloading rope 3 on a pulley (in this embodiment, a hook-and-roller pulley) 90 suspended on the unloading assisting tool 40, and the building to be unloaded is built. The frame member 6 is unloaded onto the ground. The unloading rope 3 is a natural fiber rope such as a hemp rope or cotton rope, a polypropylene rope, a vinylon rope (Cremona rope), a blended rope such as vinylon and polyethylene, or vinylon and ester.

  The unloading assisting tool 40 has a base column 41 made of a square pipe extending in the vertical direction, as shown in the external perspective views of FIGS. 3 (1) and 3 (2). By the clamp 42 and the pair of left and right engaging claws 43 and 44 that are attached to the front frame member 2, it can be detachably attached to the front vertical frame 8 of the building frame member 2. The engaging claws 43 and 44 are stepped up and down. After the base column 41 is inclined and the vertical frame 8 is inserted between the engaging claws 43 and 44, the base column 41 is set up and down vertically. The frame 8 can be engaged with one touch. An arm portion 45 made of a square pipe fixed to the upper end of the base column 41 extends obliquely upward and forward (see FIG. 6), and a U-shaped pulley mounting portion 46 is provided at the front end portion of the arm portion 45. It is installed. A pulley 90 can be detachably suspended from the pulley mounting portion 46. A reinforcing member 47 is fixed in an oblique direction between the middle of the arm portion 45 and the front side of the lower end portion of the base column 41. A hook 48 is secured on the reinforcing member 47 to hang the ring portion 5 or 7 at the end of the unloading rope 3.

  On the front side of the upper end portion of the base column 41 (on the side opposite to the clamp 42), a winding type brake unit 49 is mounted. The brake portion 49 is used to apply a brake by friction by winding the unloading rope 3 by about 3/4 or 7/4. Of the brake portion 49, 50 is a steel cylindrical body as a brake drum, and is an object to be unloaded from the unloading rope 3 that is suspended on one end of the unloading rope 3 suspended from a member to be unloaded. The rising side opposite to the member is wound. Reference numerals 51 and 52 denote annular stoppers attached to both ends of the trunk portion 50 so that the unloading rope 3 does not come off the trunk portion 50. Reference numerals 53 and 54 denote fixing plates for fixing the axial center of the body 50 to the base column 41. The shaft of the trunk portion 50 is horizontally arranged.

The body part 50 is supported by the fixing plates 53 and 54 at the center part on the back side, so that the left and right outer peripheral surfaces around which the unloading rope 3 is wound are exposed to the outside, and the body part from the outside of the body part 50 is exposed. The unloading rope 3 to 50 can be freely wound and removed. Further, since the trunk portion 50 is fixed by the fixing plates 53 and 54 so as not to rotate, when the unloading rope 3 is brought into contact with the outer peripheral surface of the trunk portion 50, a frictional force is generated, and the unloading rope 3 is moved. The brake is applied. In addition, when the contact length with which the unloading rope 3 comes into contact with the trunk portion 50 is increased, or when the force with which the unloading rope 3 in contact with the trunk portion 50 presses the trunk portion 50 is increased, the frictional force is increased, and the contact length is increased. The frictional force decreases as the length decreases or the pressing force decreases.
A hook 55 as a turning prevention portion is fixed to the upper end portion of the base column 41 toward the rear. The hook 55 has a rear end curved downward in a U-shape, and even when the unloading assisting tool 40 tries to turn left and right by fitting with the horizontal frame 4 at the top of the building frame member 2, the hook 55 is horizontal. Abutting on the frame 4 prevents the turning.

  On the upper surface of the arm portion 45, a cylindrical retaining bracket mounting portion 56 is mounted with a fixing plate 57, 58 with an opening between the upper surface of the arm portion 45 and attached to the retaining bracket mounting portion 56. A retaining bracket 59 is detachably attached. The retaining bracket 59 includes a hook 60 and a clamp 61 attached to the proximal end side of the hook 60, and is detachably attached to the retaining bracket mounting portion 56 by the clamp 61 (see FIG. 4). The retaining bracket 59 is for preventing the vertical frame 9 on the rear side of the building frame member 2 on which the unloading assisting tool 40 is installed from being pulled upward due to a load moment during unloading. That is, as shown in FIG. 5, the building frame member 2 has a pair of connecting pins 13 in which the lower ends of the vertical frames 8 and 9 are detachably fitted to the upper ends of the vertical frames 11 and 12 of the lower building frame member 10. , 14 is detachably fitted so as to be erected. Engagement projections 15 and 16, 17 and 18 are provided on the upper and lower sides of the connecting pins 13 and 14 so as to protrude laterally by springs. The engagement projections 15, 16, 17, and 18 are fitted into the drilled engagement holes 19, 20, 21, and 22, and are prevented from coming off.

  However, the engagement protrusions 15 to 18 may be broken or lost due to long-term use, and as shown in FIG. 6, the load F applied to the front end portion of the unloading assisting tool 40 is lowered by the load F applied to the building frame member 2. If a counterclockwise moment M is applied to the lower end of the vertical frame 9 with the lower end of the front vertical frame 8 as a fulcrum, the vertical frame 9 may come off from the connecting pin 14. As a countermeasure against this, as shown in FIG. 7, the retaining bracket 59 is removed from the retaining bracket mounting portion 56, the hook 60 is engaged with the rear end portion of the horizontal frame 23 of the building frame member 10, and the building frame member 2 is clamped 61. The upper and lower vertical frames 9 and 12 are fixed by detachably fastening to the lower part of the rear vertical frame 9.

FIGS. 2 and 8 are explanatory views of the unloading method by the unloading assisting tool 40 described above, and FIGS. 9 and 10 are explanatory views of a method of replacing the unloading assisting tool 40. Hereinafter, referring to these drawings, FIG. The operation of the above embodiment will be described.
As shown in FIG. 2, it is assumed that an unloading assisting tool 40 has been mounted in the vicinity of the upper end of the vertical frame 8 on the front side of the building frame member 2, one of which is erected on the uppermost stage of the bite-type temporary scaffold 1 in advance. Specifically, the engaging claws 43 and 44 on the lower back side of the base column 41 are engaged with the vertical frame 8, the hook 55 is fitted to the horizontal frame 4, and then the clamp mounted on the upper side of the base column 41. 42 is detachably fastened to the vertical frame 8. A pulley 90 for unloading is suspended from the pulley mounting portion 46. The retaining bracket 59 is removed from the retaining bracket mounting portion 56 of the unloading assisting tool 40, and the hook 60 is fitted to the horizontal frame 23 of the lower building frame member 10 on the rear side of the building frame member 2. The clamp 61 attached to the base end of the hook 60 is detachably fastened to the lower part of the vertical frame 9 on the rear side of the building frame member 2 (see FIG. 7).

  The worker A arranged on the uppermost stage hangs the unloading rope 3 on the pulley 90 and the hand side of the unloading rope 3 (the unloading rope 3 wound around the pulley 90 is a member to be unloaded. The opposite side is wound around the trunk portion 50 of the brake portion 49 by about 3/4 round (see FIG. 8). Then, the building frame member 6 to be unloaded is hung on the ring portion 5 at the lower end of the descending rope 3 a that hangs down from the pulley 90. At this time, since the arm portion 45 is directed obliquely upward and the position of the pulley 90 is high, the lower end of the building frame member 6 hung on the wheel portion 5 is placed on the scaffold stages 24 and 25 arranged by the worker A. It becomes difficult to collide, and handling of the building frame member 6 becomes easy.

The building frame member 6 is dropped to the ground while supporting the ascending rope 3b hanging from the brake portion 49 with a hand wearing leather gloves so as not to restrain the ascending movement. When the descent speed of the building frame member 6 increases, the unloading rope 3 wound around the trunk portion 50 draws a large arc (or circle) that swells radially outward of the trunk portion 50 by centrifugal force, while expanding the diameter. Since it moves, it hardly touches the surface of the body part 50, or only makes a light contact with the surface of the body part 50 with a relatively small pressing force, and little or no frictional force is generated. The building frame member 6 falls smoothly.
Since the pulley 90 is farther forward than the front surface of the bitty temporary scaffold 1, there is a distance between the building frame member 6 being unloaded and the front surface of the bitty temporary scaffold 1, and the building frame member 6 has a rising rope 3 b. There is less possibility that the lower ring portion 7 will be caught. In addition, the worker A does not need to push the lowering rope 3a forward so that the building frame member 6 being unloaded does not collide with the front surface of the temporary temporary scaffold 1, and the lower end of the lower end is controlled by hand. It is only necessary to take care that the ring portion 7 is not caught by the building frame member 6 being unloaded, and workability is improved.

When the building frame member 6 approaches the ground, the lower side rope 3b on the lower side of the body part 50 is grasped with both hands or one hand wearing leather gloves, and when the upward movement is restricted a little, the fixed body part 50 of the brake part 49 is fixed. The wound unloading rope 3 is tightened and reduced in diameter, and a large frictional force is generated by contacting the surface of the body portion 50 with a large pressing force, and a brake is applied to the movement of the unloading rope 3. Thereby, the building frame member 6 can be slowly lowered to the ground without strongly grasping the ascending rope 3b.
In addition, when applying a brake, the force which restrains the lifting movement of the unloading rope 3 by hand is moderated, and the force by which the unloading rope 3 contacting the trunk portion 50 presses the surface of the trunk portion 50 is moderated. It is possible to control the effectiveness of the brake by adjusting the frictional force caused by the contact between the body 50 and the unloading rope 3.
The worker B on the ground removes the building frame member 6 from the unloading rope 3 and piles it up in an empty space. The worker A removes the ascending rope 3b of the unloading rope 3 from the brake part 49, rotates the pulley 90 180 degrees around the hook neck, and then swaps the ascending side and the descending side of the unloading rope 3. The above work is repeated to unload other scaffold members (building frame members, scaffold stages, etc.).

When the worker A wants to change the installation location of the unloading assisting tool 40 to one level below the bite-type temporary scaffold 1, as shown in FIG. 9, the ring portion 7 on one end side of the unloading rope 3 is hung on the hook 48. The clamp 42 is removed from the vertical frame 8 of the building frame member 2 and the base column 41 is moved slightly upward to remove the hook 55 from the horizontal frame 4. Further, the base column 41 is inclined obliquely forward. The unloading assisting tool 40 is removed from the building frame member 2 by removing the pair of locking claws 43 and 44 from the vertical frame 8 while moving to the right. As shown in FIG. 10, the engaging claws 43 and 44 of the base column 41 are engaged with the front vertical frame 11 with respect to the vertical frame member 10 one step below, and the hook 55 is connected to the horizontal frame of the building frame member 10. 23 (see FIG. 7), and then fastened to the vertical frame 11 by a clamp 42 attached to the base column 41 and then replaced. The retaining bracket 59 removes the clamp 61 from the vertical frame 9 of the building frame member 2 and moves it slightly downward to remove the hook 60 from the horizontal frame 23 (see FIG. 7) of the building frame member 10, so The hook 60 may be fitted to the horizontal frame of the frame member, and the clamp 61 may be fastened to the lower portion of the vertical frame 12 of the building frame member 10 and replaced.
After that, leaving the building frame member 10, remove the scaffolding stages 24, 25 and other building frame members of the stage previously placed by the building frame member 2 and the worker A and place them on the stage one stage below the stage where the last unloading was performed. In the same manner as described above, the scaffold member removed this time is lowered to the ground.

According to this embodiment, of the building frame member 2 standing on the uppermost stage of the bite-type temporary scaffold 1, the scaffold is used by using the unloading assisting tool 40 detachably installed at the upper end of the front vertical frame 8. The member can be unloaded. Specifically, the worker A arranged on the uppermost stage of the bitty-type temporary scaffold 1 hangs the unloading rope 3 on the pulley 90 suspended from the pulley mounting portion 46 at the front end of the unloading assisting tool 40, The body 50 of the brake unit 49 is also wound about 3/4 round. Then, the building frame member 6 to be unloaded is hung on the ring portion 5 on one end side of the descending rope 3a hanging from the pulley 90. At this time, since the arm portion 45 is directed obliquely upward and the position of the pulley 90 is high, the building frame member 6 can be easily hung on the ring portion 5.
Next, the building frame member 6 is dropped on the ground while supporting the ascending rope 3b hanging from the trunk portion 50 of the brake portion 49 with a hand wearing leather gloves so as not to restrain the ascending movement. When the descent speed of the building frame member 6 increases, the unloading rope 3 wound around the trunk portion 50 moves while drawing a large arc (or circle) swelled radially outward by centrifugal force, so the surface of the trunk portion 50 The building frame member 6 can be smoothly dropped with little frictional force or little frictional force. To do. Since the pulley 90 is farther forward than the front surface of the bitty temporary scaffold 1, there is a distance between the building frame member 6 being unloaded and the front surface of the bitty temporary scaffold 1, and the building frame member 6 has a rising side rope. The possibility that the ring portion 7 at the lower end of 3b is caught is reduced. In addition, the worker A does not need to push the lowering rope 3a forward so that the building frame member 6 being unloaded does not collide with the front surface of the temporary temporary scaffold 1, and the lower end of the lower end is controlled by hand. It is only necessary to take care that the ring portion 7 is not caught by the building frame member 6 being unloaded, and workability is improved.

When the building frame member 6 comes close to the ground, the lower side rope 3b on the lower side of the trunk portion 50 is grasped with both hands or one hand wearing leather gloves, and the upward movement is restrained a little. Then, the unloading rope 3 wound around the fixed barrel portion 50 of the brake portion 49 is tightened and reduced in diameter, and a large frictional force is generated by contacting the surface of the barrel portion 50 with a large pressing force, and the brake is applied. Thereby, the building frame member 6 can be slowly lowered to the ground without strongly grasping the ascending rope 3b.
Accordingly, the physical burden on the worker A is reduced, the frictional heat between the leather gloves and the ascending rope 3a is small, there is no risk of burns, and work interruptions and delays are unlikely to occur and workability is improved. Moreover, the leather gloves are less damaged and economical. Moreover, since only a leather glove should just fit in a hand, it does not become thick but this also improves workability | operativity. Further, since it is not necessary to hold both the descending rope 3a and the ascending rope 3b together when the brake is applied, the risk of the ascending rope 3b being caught by the building frame member 6 to be unloaded is reduced.
In addition, when applying a brake, the force which restrains the lifting movement of the unloading rope 3 by hand is moderated, and the force by which the unloading rope 3 contacting the trunk portion 50 presses the surface of the trunk portion 50 is moderated. It is possible to control the effectiveness of the brake by adjusting the frictional force caused by the contact between the body 50 and the unloading rope 3.
In addition, the trunk portion 50 is supported by the fixing plate 53, 54 at the central portion on the back side, so that the left and right outer peripheral surfaces around which the unloading rope 3 is wound are exposed to the outside. The unloading rope 3 can be freely wound around and removed from the trunk portion 50.
Also, the unloading assisting tool 40 is installed on the building frame member 2 by engaging the engaging claws 43 and 44 of the base column 41 with the front vertical frame 8 and fitting the hook 55 with the horizontal frame 4. It is only necessary to fasten to the vertical frame 8 by the clamp 42 attached to the support column 41, and a simple operation is sufficient.
Further, by fitting the hook 55 fixed to the upper end of the base column 41 to the horizontal frame 4, even if the unloading assisting tool 40 tries to turn left and right, the hook 55 abuts against the horizontal frame 4 to prevent the turning. The direction can be fixed with a simple structure so that the unloading aid 40 does not turn carelessly.
Further, the retaining bracket 59 can fix the lower portion of the vertical frame 9 on the rear side of the building frame member 2 and the rear end portion of the horizontal frame 23 of the next lower building frame member 10, Even if a downward load is applied to the front end portion of the portion 45, there is no possibility that the vertical frame 9 comes off from the vertical frame 12 of the building frame member 10.

In the above-described embodiment, an example is shown in which the arm portion extends obliquely upward in the forward direction. However, the present invention is not limited to this, and the arm portion may be extended horizontally in the forward direction.
Further, in the above-described embodiment, an example in which a pair of engaging claws having a step is fixed to the lower part on the back side of the base support column, but the pair of engaging claws may be replaced with the same clamp as the upper part on the back side. good.
Moreover, although the above-mentioned Example demonstrated the case where it was set as the type which installs an unloading auxiliary tool in the building frame member of a bitty type temporary scaffold, it is good also as a type installed in the building strut of a wedge-tight temporary scaffold. Specifically, like the unloading assisting tool 40A shown in FIGS. 11 and 12, the unloading assisting tool 40 of the first embodiment shown in FIG. The wedge portion 62 is fixed, and the hook 55, the retaining bracket attaching portion 56, and the retaining bracket 59 are omitted. At the time of use, as shown in FIG. 11, after engaging the engaging claws 43, 44 of the base column 41 with the building column 26, which is standing on the top of the wedge-tight temporary scaffold, the base column 41 is engaged. The wedge portion 62 fixed to the housing is hammered into the pocket 27 of the building strut 26 with a hammer, and can be attached in a non-turnable and detachable manner simply by tightening, so that a simple mounting operation is sufficient.

Further, in the above-described embodiment, the brake is applied by the friction force generated by the contact between the surface of the steel body portion of the brake portion and the unloading rope, but the friction member is applied to all or part of the surface of the body portion. And a larger frictional force than that of the steel body surface may be generated.
Specifically, as in the unloading assisting tool 40B shown in FIG. 13 (1), the rope through holes 63 and 64 are drilled in the annular stoppers 51 and 52 fixed to both sides of the body part 50 of the brake part 49B. At the same time, rope through-holes 65 and 66 are formed in the middle portion 50 between the stopper 51 and the fixing plate 53 and between the fixing plate 54 and the stopper 52. 13 (2), a friction rope 67 as a friction member made of the same material as that of the unloading rope 3 is wound around the entire surface of the trunk portion 50, and both ends are passed through the rope through holes 63 and 64 and the stopper 51 , 52, make knots 68 and 69 so that they cannot be unwound. When the brake is applied, a large frictional force can be generated by the contact between the unloading rope 3 and the friction rope 67.
Alternatively, as shown in FIG. 13 (3), the friction rope 70 is passed through the rope passage hole 65 of the trunk portion 50, and the tip is pulled out from the hole 71 of the trunk portion 50 to form a knot (not shown). Pull the part that goes out from 65 to hit the knot against the back side of the rope through hole 65, wind up to the stopper 51 around the surface of the trunk 50, pass through the rope through hole 63, and make the knot 72 outside the stopper 51 Do not. Similarly, the friction rope 73 is passed through the rope passage hole 66 of the trunk portion 50, and the tip is pulled out from the hole 71 of the trunk portion 50 to form a knot (not shown). The knot is pulled and applied to the back side of the rope passage hole 66, wound up to the stopper 52 around the surface of the trunk portion 50, passed through the rope passage hole 64, and a knot 74 is formed outside the stopper 52 so as not to be unwound. When the unloading rope 3 is wound around the brake part 49B in the preparation work of the unloading assisting tool 40B, a large friction is obtained by using a portion of the surface of the body part 50 where the friction ropes 70 and 73 are not wound. The unloading rope 3 can be arranged smoothly without receiving resistance (see FIG. 14 (1)). On the other hand, when the brake is applied during unloading, a large frictional force can be generated by shifting the ascending rope 3b by hand and applying it to the portion around which the friction rope 70 or 73 is wound (FIG. 14 ( 2)).

  In the case of FIG. 13 (3), as in the unloading assisting tool 40C shown in FIG. 15 (1), the cut portions 75 and 76 are formed by hanging from the front to the bottom of the stoppers 51C and 52C, and the cut portions Between the stoppers 51C and 52C other than 75 and 76 and the peripheral surface of the body portion 50, the inclined guides 77 and 78 are inclined so as to cover the upper and lower sides of the friction rope 70, and the upper and lower sides of the friction rope 73 are inclined. A brake portion 49C fitted with guides 79 and 80 may be used (see FIG. 15 (2)). The inclined guides 77 and 78 and 79 and 80 are used to guide the unloading rope 3 to the surface near the center of the trunk 50 even if the unloading rope 3 is to be wound on the friction rope 70 or 73. When the unloading rope 3 is wound around the brake portion 49C in the preparation work of the unloading assisting tool 40C, the friction rope 70, of the surface of the trunk portion 50 is guided by the inclined guides 77 and 78, or 79 and 80. 73 can be easily disposed on the unrolled portion (see FIG. 15 (2)). On the other hand, when the brake is applied during unloading, the lower rope 3b on the lower side of the brake part 49C is obliquely shifted outward from the cut part 75 or 76 by hand, thereby reliably winding the friction rope 70 or 73. It can be applied to the portion (see FIG. 15 (3)).

Next, a second embodiment of the present invention will be described with reference to FIGS. 16 is a perspective view showing a usage state of the unloading assisting tool embodying the unloading method according to the present invention, and FIG. 17 is an external perspective view of the unloading assisting tool in FIG. In these drawings, the same components as those in FIG. 2 are denoted by the same reference numerals.
In FIG. 16, reference numeral 1 denotes a bite-type temporary scaffold in the middle of dismantling, and a building frame member 2 is erected on the uppermost stage, and the entire steel frame is placed above the vertical frame 8 on the front side of the building frame member 2. A product unloading assisting tool 140 is detachably mounted. The worker A on the uppermost stage hangs the unloading rope 3 on a pulley (in this embodiment, a hook-and-neck pulley) 90 suspended on the unloading assisting tool 140, and the building to be unloaded is built. The frame member 6 is unloaded onto the ground. The unloading rope 3 is a natural fiber rope such as a hemp rope or cotton rope, a polypropylene rope, a vinylon rope (Cremona rope), a blended rope such as vinylon and polyethylene, or vinylon and ester.

  The unloading assisting tool 140 has a base column 41 made of a steel square pipe extending in the vertical direction, as shown in the external perspective views of FIGS. 17 (1) and (2). The clamp 42 and the engaging claw 143 attached to the upper part and the lower part can be detachably attached to the front vertical frame 8 of the building frame member 2. An arm portion 45 made of a steel square pipe fixed to the upper end of the base column 41 extends obliquely upward and forward (see FIG. 18), and a U-shaped pulley is attached to the front end portion of the arm portion 45. Part 46 is mounted. A pulley 90 can be detachably suspended from the pulley mounting portion 46. A steel reinforcing member 47 is fixed obliquely between the middle of the lower surface of the arm portion 45 and the front side of the lower end portion of the base column 41. A bracket is formed by the base column 41, the clamp 42, the engaging claw 143, the arm portion 45, and the reinforcing member 47. The base column 41 forms the base of the bracket, and the front end of the arm portion 45 is the front end of the bracket.

  On the front side of the upper end portion of the base column 41 (on the side opposite to the clamp 42), a steel-wound brake portion 49 is mounted. The brake portion 49 is used to wrap the unloading rope 3 and apply a brake by friction. Among the brake parts 49, 50 is a cylindrical body part as a brake drum around which the unloading rope 3 is wound, and the central axis is disposed horizontally in the left-right direction. Reference numerals 51 and 52 denote annular stoppers attached to both ends of the trunk portion 50 so that the unloading rope 3 wound around the outer peripheral surface of the trunk portion 50 does not come off from the trunk portion 50. Reference numerals 53 and 54 denote fixing plates for fixing the axial center of the body portion 50 near the upper end on the front side of the base column 41. The trunk portion 50 is extended on both the left and right sides when viewed from the back side of the base column 41, and the operator can unload the unloading rope 3 around the left side portion or the right side portion of the trunk portion 50.

  A hook 55 as a turning prevention portion is fixed to the upper end portion of the base column 41 toward the rear. The hook 55 has a rear end curved downward in a U-shape, and even if the bracket constituting the unloading assisting tool 140 is swung left and right by fitting it into the horizontal frame 4 at the top of the building frame member 2, The hook 55 comes into contact with the horizontal frame 4 to prevent the turning.

  A pair of upper and lower L-shaped rope hooks (rope hooks) 156 and 157, 158 and 159 are fixed to the left and right side surfaces of the lower portion of the base column 41. A pair of upper and lower rope hooks 156 and 157 or 158 and 159 is a rope hook that temporarily restrains the movement of the unloading rope 3 by hanging the unloading rope 3 around a figure 8 or the like. As a function. By holding the unloading rope 3 on the rope hanging portions 156 and 157 or 158 and 159, the unloading rope 3 does not move even if both hands are released from the unloading rope 3, and both hands are used when preparing for unloading. The unloading target building frame member 6 is hung on the ring part 5 or the ring part 7 of the unloading rope 3, or the unloading target building frame member 6 hung on the ring part 5 or the ring part 7 from the scaffolding stage. You can drop it forward.

FIGS. 16 and 18 to 20 are explanatory diagrams of the unloading method by the unloading assisting tool 140 described above, and FIGS. 21 and 22 are explanatory diagrams of the replacement method of the unloading assisting tool 40, which will be described below. The operation of the above embodiment will be described with reference to FIG.
As shown in FIGS. 16 and 18, the unloading assisting tool 140 has been mounted in the vicinity of the upper end of the vertical frame 8 on the front side of the building frame member 2 that is preliminarily placed on the uppermost stage of the bitty temporary scaffold 1. And Specifically, the engaging claw 143 on the lower back side of the base column 41 is engaged with the vertical frame 8, and the hook 55 is fitted to the horizontal frame 4, and then the clamp 42 mounted on the upper back side of the base column 41. It is fastened to the vertical frame 8 so as to be detachable. A pulley 90 for unloading is suspended from the pulley mounting portion 46.

  The worker A placed on the uppermost stage hangs the unloading rope 3 on the pulley 90 with leather gloves fitted on both hands, and the hand side of the unloading rope 3 is the outer peripheral surface of the trunk portion 50 of the brake portion 49. (The amount of wrapping around the body 50 is adjusted by the weight of the suspended load, the distance from the ground to the pulley 90, etc.). Further, the ascending rope 3b on the lower side of the trunk 50 is wrapped around the rope hooks 156 and 157 (or the rope hooks 158 and 159) in the shape of figure 8 to temporarily restrain the rising movement. (See FIG. 19). Then, on the uppermost stage, the worker A uses both hands to hang the building frame member 6 to be unloaded on the ring portion 5 at the lower end of the descending rope 3a hanging from the pulley 90. Then, the unloading target building frame member 6 hung on the ring portion 5 is dropped forward from the scaffold stage. At this time, since the arm portion 45 is directed obliquely upward and the position of the pulley 90 is high, the lower end of the building frame member 6 hung on the wheel portion 5 is placed on the scaffold stages 24 and 25 arranged by the worker A. It becomes difficult to collide, and handling of the building frame member 6 becomes easy. Since the movement of the unloading rope 3 is restricted, the dropped building frame member 6 is suspended by the pulley 90 via the unloading rope 3 and has not yet been lowered.

Next, the ascending rope 3b is removed from the rope hooks 156 and 157 (or the rope hooks 158 and 159) (see FIG. 20), and the ascending rope 3b hanging from the brake 49 is not restrained from being lifted. The building frame member 6 is dropped to the ground while being supported by a gloved hand. When the descent speed of the building frame member 6 increases, the unloading rope 3 wound around the trunk portion 50 draws a large arc (or circle) that swells radially outward of the trunk portion 50 by centrifugal force, while expanding the diameter. Since it moves, it hardly touches the surface of the body part 50, or only makes a light contact with the surface of the body part 50 with a relatively small pressing force, and little or no frictional force is generated. The building frame member 6 falls smoothly.
Since the pulley 90 is farther forward than the front surface of the bitty temporary scaffold 1, there is a distance between the building frame member 6 being unloaded and the front surface of the bitty temporary scaffold 1, and the building frame member 6 has a rising side rope. The possibility that the ring portion 7 at the lower end of 3b is caught is reduced. In addition, the worker A does not need to push the lowering rope 3a forward so that the building frame member 6 being unloaded does not collide with the front surface of the temporary temporary scaffold 1, and the lower end of the lower end is controlled by hand. It is only necessary to be careful that the ring portion 7 is not caught by the building frame member 6 being unloaded, and workability is improved (see FIG. 16).

When the building frame member 6 approaches the ground, when the worker A grasps the ascending rope 3b with both hands or one hand wearing leather gloves and restrains the upward movement a little, the worker A is wound around the fixed body portion 50 of the brake portion 49. The unloading rope 3 is tightened to reduce the diameter, and is brought into contact with the surface of the body portion 50 with a large pressing force, so that a large frictional force is generated and a brake is applied. Thereby, the building frame member 6 can be slowly lowered to the ground without strongly grasping the ascending rope 3b. The worker B on the ground may remove the building frame member 6 from the unloading rope 3 and stack it in an empty space.
After one unloading, the worker A removes the ascending rope 3b of the unloading rope 3 from the brake portion 49, rotates the pulley 90 180 degrees around the hook neck, and descends with the ascending side of the unloading rope 3. After replacing the sides, the same work is repeated to unload other scaffold members (building frame members, scaffold stages, etc.).

When the worker A wants to change the installation location of the unloading assisting tool 140 to one level below the temporary temporary scaffold 1, as shown in FIG. 21, the ring portion 7 (or the ring portion 5) on one end side of the unloading rope 3. Is hung on the rope hook 159 so that it does not fall off, the clamp 42 is removed from the vertical frame 8 of the building frame member 2 and the base column 41 is moved slightly upward to remove the hook 55 from the horizontal frame 4, The unloading assisting tool 140 is removed from the building frame member 2. Then, as shown in FIG. 22, the engaging claw 143 of the base column 41 is engaged with the front vertical frame 11 and the hook 55 is attached to the horizontal frame 23 of the building frame member 10. After fitting, the clamp 42 attached to the base column 41 may be fastened to the vertical frame 11 and replaced.
After that, leaving the building frame member 10, remove the scaffolding stages 24, 25 and other building frame members of the stage previously placed by the building frame member 2 and the worker A and place them on the stage one stage below the stage where the last unloading was performed. In the same manner as described above, the scaffold member removed this time is lowered to the ground.

According to the second embodiment, the unloading assisting tool 140 detachably installed at the upper end of the front vertical frame 8 out of the building frame member 2 standing on the uppermost stage of the bitty temporary scaffold 1 is used. Can unload the scaffolding member. Specifically, the worker A placed on the uppermost stage of the temporary temporary scaffold 1 unloads the pulley 90 suspended on the pulley mounting portion 46 at the front end of the unloading assisting tool 140 with leather gloves on both hands. The rope 3 is hung, and the trunk portion 50 of the brake portion 49 is also wound about a quarter or several times. Further, the unloading rope 3 below the trunk portion 50 is wound around the rope hooking portions 156 and 157 (or 158 and 159) to temporarily restrain the movement. Then, both hands are separated from the unloading rope 3, and the building frame member 6 to be unloaded is hung on the ring part 5 on one end side of the descending rope 3 a hanging down from the pulley 90 on the uppermost stage. The building frame member 6 to be unloaded is dropped forward. At this time, since the arm portion 45 is directed obliquely upward and the position of the pulley 90 is high, the lower end of the building frame member 6 hung on the wheel portion 5 is placed on the scaffold stages 24 and 25 arranged by the worker A. It becomes difficult to collide, and handling of the building frame member 6 becomes easy.
Next, the ascending rope 3b is removed from the rope hooks 156 and 157 (or the rope hooks 158 and 159) (see FIG. 20), and the ascending rope 3b hanging from the brake 49 is not restrained from being lifted. The building frame member 6 is dropped to the ground while being supported by a gloved hand. When the descent speed of the building frame member 6 increases, the unloading rope 3 wound around the trunk portion 50 draws a large arc (or circle) swelled radially outward by centrifugal force, and moves while expanding in diameter. The frame 50 is hardly in contact with the surface of the portion 50 or only lightly contacts the surface of the body portion 50 with a relatively small pressing force. The member 6 falls.
Since the pulley 90 is farther forward than the front surface of the bitty temporary scaffold 1, there is a distance between the building frame member 6 being unloaded and the front surface of the bitty temporary scaffold 1, and the building frame member 6 has a rising side rope. The possibility that the ring portion 7 at the lower end of 3b is caught is reduced. Further, the worker A does not need to push the lowering rope 3a forward so that the building frame member 6 being unloaded does not collide with the front of the temporary temporary scaffolding 1, and controls the ascending rope 3b by hand. It is only necessary to be careful not to catch the ring portion 7 on the building frame member 6 being unloaded, and workability is improved.

When the building frame member 6 approaches the ground, the ascending rope 3b is grasped with both hands or one hand wearing leather gloves, and the upward movement is restrained a little. Then, the unloading rope 3 wound around the brake part 49 is tightened to reduce the diameter, and a large frictional force is generated by contacting the surface of the body part 50 with a large pressing force, and the brake is applied. Thereby, the building frame member 6 can be slowly lowered to the ground without strongly grasping the ascending rope 3b.
Accordingly, the physical burden on the worker A is reduced, the frictional heat between the leather gloves and the ascending rope 3a is small, there is no risk of burns, and work interruptions and delays are unlikely to occur and workability is improved. Moreover, the leather gloves are less damaged and economical. Moreover, since only a leather glove should just fit in a hand, it does not become thick but this also improves workability | operativity. Further, since it is not necessary to hold both the descending rope 3a and the ascending rope 3b together when the brake is applied, the risk of the ascending rope 3b being caught by the building frame member 6 to be unloaded is reduced.
Further, the unloading assisting tool 140 is installed on the building frame member 2 by engaging the engaging claw 143 of the base column 41 with the front vertical frame 8 and fitting the hook 55 with the horizontal frame 4. It is only necessary to fasten it to the vertical frame 8 by the clamp 42 attached to the, so that a simple operation is sufficient.
Further, by fitting the hook 55 fixed to the upper end of the base column 41 to the horizontal frame 4, even if the unloading assisting tool 140 tries to turn left and right, the hook 55 abuts against the horizontal frame 4 to prevent the turning. The direction can be fixed with a simple structure so that the unloading assisting tool 140 does not turn carelessly.

In the above-described second embodiment, an example is shown in which the arm portion extends obliquely upward in the forward direction. However, the present invention is not limited to this, and the arm portion may be extended horizontally in the forward direction. good.
Moreover, although the example which fixed the engaging claw to the lower part of the back side of a base support | pillar was given, you may replace an engaging claw with the same clamp as the upper part of a base support | pillar back side.
Moreover, you may make it provide a pair of rope hook part in the right-and-left both sides of a reinforcement member instead of providing in the right-and-left both sides of a base support | pillar.
Also, the upper rope hanging portion (reference numerals 156 and 158 in FIG. 17) is omitted, and only the lower rope hanging portion (reference numerals 157 and 159 in FIG. 17) is left, and among the unloading ropes wound around the trunk portion, The ascending movement may be temporarily constrained by winding the ascending rope on the lower side of the trunk part around the lower rope hook part and then winding it again on the trunk part.
Further, the hook for preventing turning may be omitted.

  Further, in the second embodiment described above, the case where the unloading assisting tool is set to the type installed on the building frame member of the bite-type temporary scaffold has been described, but the type to be installed on the building strut of the wedge-type temporary scaffold can also be used. good. Specifically, like the unloading aid 140A shown in FIGS. 23 and 24, the clamp 42 on the upper back side of the base column 41 in the unloading aid 140 of the second embodiment shown in FIGS. 16 and 17. Instead of this, the wedge part 62 is fixed. The wedge part 62 can be removably fitted into the pocket 27 of the building strut 26 of the wedge-tight temporary scaffold. In use, as shown in FIG. 23, the engaging claw 143 of the base column 41 is engaged with the building column 26 with respect to the building column 26 standing on the top of the wedge-tightened temporary scaffold, By simply fitting the fixed wedge portion 62 into the pocket 27 of the building strut 26, the wedge portion 62 can be mounted in a non-turnable and detachable manner. In addition, in the unloading assisting tool 140 </ b> A of FIGS. 23 and 24, the building strut 26 and a detachable clamp may be provided between the wedge portion 62 on the back side of the base strut 41 and the engaging claw 143.

  Further, in the second embodiment described above, the example in which the winding type brake portion is provided on the upper end portion on the front side of the base column is shown, but it may be provided on the lower end portion on the front side of the base column. Or you may make it equip | install in the location near a base support | pillar among arm parts, or equip in the location near a base support | pillar among the reinforcement members fixed between the arm part and the base support | pillar. Specifically, like the unloading assisting tool 140B shown in FIG. 25 (1), a cylindrical trunk portion 150B extending left and right so as to intersect a portion of the arm portion 45 close to the base column 41. May be fixed, and annular stoppers 51 and 52 may be fixed to both ends of the body portion 150B to form a wrapping brake portion 149B. Alternatively, as in the unloading assisting tool 140C shown in FIG. 25 (2), the cylindrical body portion 150C extending to the left and right is fixed so as to intersect a portion of the reinforcing member 47 close to the base column 41. Alternatively, the annular stoppers 51 and 52 may be fixed to both ends of the body portion 150C to constitute the winding type brake portion 149C.

Further, in the second embodiment described above, the brake is applied by the frictional force generated by the contact between the outer peripheral surface of the steel barrel portion of the brake portion and the unloading rope. A friction member such as a rope, a leather sheet, a rubber sheet, or a cloth sheet is attached to the surface of the body part 50 so as to cover the part so that a larger frictional force is generated as compared with the steel body surface. Also good.
Specifically, for example, as in the unloading assisting tool 140D shown in FIG. 26 (1), the rope through holes 63 and 64 are drilled in the annular stoppers 51 and 52 fixed to both sides of the trunk portion 150D of the brake portion 149D. In addition, rope through holes 65 and 66 are formed in the middle of the barrel portion 150D between the stopper 51 and the fixing plate 53 and between the fixing plate 54 and the stopper 52. Then, as shown in FIG. 26 (2), a friction rope 67 as an example of a friction member is wound once around the entire outer peripheral surface of the trunk portion 150D, and both ends are passed through the rope through holes 63 and 64 and outside the stoppers 51 and 52. By making the knots 68 and 69 so as not to be broken, the entire surface of the trunk portion 150D is covered. For the friction rope 67, the same hemp rope as the unloading rope, natural fiber rope such as cotton rope, polypropylene rope, vinylon rope (Cremona rope), vinylon and polyethylene, mixed twisted rope such as vinylon and ester, etc. Can do. When the brake is applied, a large frictional force can be generated by the contact between the unloading rope 3 and the friction rope 67.

Alternatively, as shown in FIG. 26 (3), the friction rope 70 is passed through the rope passage hole 65 of the trunk portion 150D, and the tip is pulled out from the hole 71 of the trunk portion 150D to form a knot (not shown). Pull the portion that has come out of 65 to hit the knot against the back side of the rope passage hole 65, wind up to the stopper 51 around the outer peripheral surface of the trunk portion 150 </ b> D, pass it through the rope passage hole 63, and make a knot 72 outside the stopper 51. By making it not unraveled, it covers one end portion of the outer peripheral surface of the body portion 150D. Similarly, the friction rope 73 is passed through the rope passage hole 66 of the trunk portion 150D, and the tip is pulled out from the hole 71 of the trunk portion 150D to form a knot (not shown). By pulling and applying the knot to the back side of the rope passage hole 66, winding the stopper 52 around the outer peripheral surface of the trunk portion 150 </ b> D through the rope passage hole 64, and making a knot 74 on the outside of the stopper 52 so that it cannot be unwound. Cover the other end of the outer peripheral surface of the body 150D.
When the unloading rope 3 is wound around the brake part 149D in the preparation work of the unloading assisting tool 140D, it is large by using a part of the outer peripheral surface of the body part 150D where the friction ropes 70 and 73 are not wound. The unloading rope 3 can be arranged smoothly without receiving frictional resistance (see FIG. 27 (1)). On the other hand, when the brake is applied during unloading, a large frictional force can be generated by shifting the ascending rope 3b by hand and applying it to the portion around which the friction ropes 70 and 73 are wound (FIG. 27 ( 2)).

  In the case of FIG. 26 (3), like the unloading assisting tool 140E shown in FIG. 28 (1), the stoppers 51E and 52E fixed to both sides of the body portion 150D are hung from the front to the bottom and from below. In the rear, cut portions 175 and 176 are formed, and four inclined guide bars 177 are formed between the stoppers 51E and 52E and the outer peripheral surface of the trunk portion 150D so as to cover the top and bottom and the front and rear of the friction rope 70. A brake portion 149E may be used in which four inclined guide bars 178 are mounted so as to cover the top and bottom and front and rear of the friction rope 73 (see FIG. 28 (2)). The inclined guide bars 177 and 178 are for guiding the unloading rope 3 to the surface near the center of the trunk portion 150D even if the unloading rope 3 is to be wound on the friction rope 70 or 73. When the unloading rope 3 is wound around the brake part 149E in the preparation work of the unloading assisting tool 140E, it is guided by the inclined guide bar 177 or 178, and the friction ropes 70 and 73 of the outer peripheral surface of the trunk part 150D. It can be easily disposed in a portion that is not wound (see FIG. 28 (2)). On the other hand, when the brake is applied during unloading, the lower rope 3b on the lower side of the brake part 149E is obliquely shifted outward from the cut part 175 or 176 by the hand, thereby reliably winding the friction rope 70 or 73. The ascending rope 3b can be applied to the portion (see FIG. 28 (3)).

In the second embodiment described above, the pulley is suspended from the pulley mounting portion attached to the front end portion of the arm portion, and the unloading rope is wound around the pulley and then wound around the trunk portion of the brake portion. However, instead of the pulley mounting portion, a sheave around which the unloading rope is wound may be attached to the front end portion of the arm portion.
In addition, instead of the pulley mounting part at the front end of the arm, a rope hanging part for slidably hanging the unloading rope is provided, and after the unloading rope is wrapped around the rope hanging part, it is wound around the body of the brake part. Anyway.

Stoppers 181 and 182 are attached. Of the arm portion 45F, a rope hanging portion for slidably suspending the unloading rope is configured by the portion on the front side from the rope hanging member 180, the rope hanging member 180, and the stoppers 181 and 182.
During use, as shown in FIG. 30 (1), the unloading rope 3 is hung on the upper side of the arm portion 45F on the front side of the rope hooking member 180, and further wound around the rope hooking member 180 and then wound around the brake portion 149F. Alternatively, as shown in FIG. 30 (2), when the unloading rope 3 is hung on the front side of the rope hooking member 180 in the arm portion 45F and is wound around the brake portion 149F through the lower side of the arm portion 45F, the lowering is performed. The side rope 3a can be suspended from the front end portion of the arm portion 45F. Since the arm portion 45F and the rope hanging member 180 are made of a round pipe, the unloading rope 3 can smoothly slide and move with respect to the front end portion of the arm portion 45F and the rope hanging member 180 during unloading.

  In the modification shown in FIG. 29, the brake portion is provided near the base column in the arm portion.

(See FIG. 37 (2)).

Next, a third embodiment of the present invention will be described with reference to FIGS. 38 is a perspective view showing a use state of the unloading assisting tool embodying the unloading method according to the present invention, and FIG. 39 is an external perspective view of the unloading assisting tool in FIG. In these drawings, the same components as those in FIG. 2 are denoted by the same reference numerals.
In FIG. 38, reference numeral 200 denotes a building such as a building or a condominium, 201 denotes a temporary temporary scaffolding in the middle of dismantling installed on the front side of the building. A vertical frame is temporarily fixed to the front surface of the building 200 by anchor bolts 202. A building frame member 2 is erected on the uppermost stage of the temporary temporary scaffold 201, and a whole steel unloading auxiliary tool 240 is detachably attached to the upper part of the vertical frame 8 on the front side of the building frame member 2. It is attached to. The worker A on the uppermost stage hangs the unloading rope 3 on a pulley (in this embodiment, a hook-and-neck pulley) 90 suspended on an unloading assisting tool 240, and the building to be unloaded is built. The frame member 6 is unloaded onto the ground. The unloading rope 3 is a natural fiber rope such as a hemp rope or cotton rope, a polypropylene rope, a vinylon rope (Cremona rope), a blended rope such as vinylon and polyethylene, or vinylon and ester.

The unloading assisting tool 240 has a base column 41 made of a steel square pipe extending in the vertical direction as shown in the external perspective views of FIGS. 39 (1) and (2). The clamp 42 and the engaging claw 143 attached to the upper part and the lower part can be detachably attached to the front vertical frame 8 of the building frame member 2. An arm portion 245 made of a steel square pipe fixed to the upper end of the base column 41 extends obliquely upward and forward (see FIG. 41), and has a U-shape near the front end of the arm portion 245 and at the front end. A pulley attachment portion 46 and a guide rope attachment portion 210 are attached. A pulley 90 can be detachably suspended from the pulley mounting portion 46. A hook 212 to which one end side of the guide rope 211 is attached is detachably suspended from the guide rope attaching portion 210. The guide rope 211 is used to prevent a building frame member or the like being unloaded from colliding with the front surface of the bite-type temporary scaffold 1. A semi-circular suspension rope stopper 213 near the pulley mounting portion 46 on the upper surface of the arm portion 245, and a pair of front and rear L-shaped suspension rope hooks (near the base of the upper surface of the arm portion 245) Suspension rope hooks 214, 215 are fixed. After the suspension rope 216 having one end fixed on the roof of the building 200 is inserted into the carabiner 217 fitted to the suspension rope stopper 213 and is hooked, the suspension rope hooks 214 and 215 are shaped like eight characters. The building frame member 2 to which the unloading assisting tool 240 is attached is prevented from being inclined forward by the weight of the unloading member by being wrapped around the shape or the like. The suspension rope stopper 213 and the suspension rope hooks 214 and 215 form an example of a suspension rope mounting portion.
A steel reinforcing member 47 is fixed obliquely between the middle of the lower surface of the arm portion 245 and the front side of the lower end portion of the base column 41. A bracket is formed by the base column 41, the clamp 42, the engaging claw 143, the arm portion 245, and the reinforcing member 47. The base column 41 forms the base of the bracket, and the front end of the arm portion 245 is the front end of the bracket.

  On the front side of the upper end portion of the base column 41 (on the side opposite to the clamp 42), a steel-wound brake portion 49 is mounted. The brake portion 49 is used to wrap the unloading rope 3 and apply a brake by friction. Among the brake parts 49, 50 is a cylindrical body part as a brake drum around which the unloading rope 3 is wound, and the central axis is disposed horizontally in the left-right direction. Reference numerals 51 and 52 denote annular stoppers attached to both ends of the trunk portion 50 so that the unloading rope 3 wound around the outer peripheral surface of the trunk portion 50 does not come off from the trunk portion 50. Reference numerals 53 and 54 denote fixing plates for fixing the axial center of the body portion 50 near the upper end on the front side of the base column 41. The trunk portion 50 is extended on both the left and right sides when viewed from the back side of the base column 41, and an operator can hang the unloading rope 3 on the left side portion or the right side portion of the trunk portion 50.

  A hook 55 as a turning prevention portion is fixed to the upper end portion of the base column 41 toward the rear. The hook 55 has a rear end curved downward in a U-shape, and even when the bracket constituting the unloading assisting tool 240 is turned to the left and right by fitting into the horizontal frame 4 at the top of the building frame member 2, The hook 55 comes into contact with the horizontal frame 4 to prevent the turning.

  A pair of upper and lower L-shaped rope hooks (rope hooks) 156 and 157, 158 and 159 are fixed to the left and right side surfaces of the lower portion of the base column 41. The rope hanging portions 156 and 157 or 158 and 159 function as a rope hanging portion that temporarily restrains the movement of the unloading rope 3 by hanging the unloading rope 3 around the shape of figure 8, etc. Have By holding the unloading rope 3 on the rope hanging portions 156 and 157 or 158 and 159, the unloading rope 3 does not move even if both hands are released from the unloading rope 3, and both hands are used when preparing for unloading. The unloading target building frame member 6 is hung on the ring part 5 or the ring part 7 of the unloading rope 3, or the unloading target building frame member 6 hung on the ring part 5 or the ring part 7 from the scaffolding stage. You can drop it forward.

FIGS. 38 and 40 to 43 are explanatory diagrams of the unloading method by the unloading assisting tool 240 described above, and FIGS. 44 to 48 are explanatory diagrams of the replacement method of the unloading assisting tool 240, which will be described below. The operation of the above embodiment will be described with reference to FIG.
As shown in FIG. 40, it is assumed that the unloading assisting tool 240 has been mounted in the vicinity of the upper end of the vertical frame 8 on the front side of the building frame member 2 that is preliminarily placed on the uppermost stage of the bitty-type temporary scaffold 201. Specifically, the engaging claw 143 on the lower back side of the base column 41 is engaged with the vertical frame 8, and the hook 55 is fitted to the horizontal frame 4, and then the clamp 42 mounted on the upper back side of the base column 41. It is fastened to the vertical frame 8 so as to be detachable. A pulley 90 for unloading is suspended from the pulley mounting portion 46. Further, a suspension rope 216 having one end fixed to the roof of the building 200 is passed through a carabiner 217 fitted in a hole of the semi-circular suspension rope stopper 213, and the suspension rope 216 is suspended in a stretched state. The arm portion 245 of the unloading assisting tool 240 is suspended by being wound around the rope hanging portions 214 and 215 and temporarily fixed. The other end side of the suspension rope 216 is hung down after being hung on the upper end of the vertical frame 9 on the rear side (building side) of the building frame member 2. When disassembling the bite-type temporary scaffold 201, the worker C first removes the anchor bolt (reference numeral 202A in FIG. 40) near the uppermost stage of the undisassembled portion, and completes the bolt hole filling work. For this reason, when a load of the unloading target member is applied to the unloading assisting tool 240, the building frame member 2 is easily inclined forward, but the arm portion 245 of the unloading assisting tool 240 is suspended by the suspension rope 216. By doing so, forward tilt is suppressed. A hook 212 is suspended from the guide rope attaching portion 210, and the lower side of the guide rope 211 having the upper end attached to the hook 212 is hung down to the ground. It is fixed to a heavy object 218 installed on the ground in a stretched state. The heavy object 218 is placed slightly forward from directly below the guide rope attachment part 210.

  The worker A placed on the uppermost stage hangs the unloading rope 3 on the pulley 90 with leather gloves fitted on both hands, and the hand side of the unloading rope 3 is the outer peripheral surface of the trunk portion 50 of the brake portion 49. (The amount of wrapping around the body 50 is adjusted by the weight of the suspended load, the distance from the ground to the pulley 90, etc.). Further, the lower side rope 3b on the lower side of the body part 50 is wrapped around the rope hooks 158 and 159 (or the rope hooks 156 and 157) in the shape of figure 8 to temporarily restrain the upward movement. deep. Next, the load is applied to one of the two carabiners 219 and 220 fitted to the ring portion 5 as the load side end portion of the lower end rope 3a hanging from the pulley 90 via the sling rope 221. The building frame member 6 to be lowered is suspended. Then, the building frame member 6 to be unloaded with both hands is dropped forward from the scaffold stage. At this time, since the arm portion 245 is directed obliquely upward and the position of the pulley 90 is high, the lower end of the building frame member 6 suspended from the wheel portion 5 is placed on the scaffold stages 24 and 25 arranged by the worker A. It becomes difficult to collide, and handling of the building frame member 6 becomes easy. Since the movement of the unloading rope 3 is restricted, the dropped building frame member 6 is suspended by the pulley 90 via the unloading rope 3 and has not yet been lowered. Next, the guide rope 211 is inserted and suspended in the other carabiner 219 fitted to the ring portion 5 of the descending rope 3a (see FIG. 41).

  Next, remove the ascending rope 3b from the rope hooks 158 and 159 (or the rope hooks 156 and 157) and put on leather gloves so as not to restrain the ascending movement of the ascending rope 3b hanging from the brake part 49. The building frame member 6 is dropped to the ground while being supported. When the descent speed of the building frame member 6 increases, the unloading rope 3 wound around the trunk portion 50 draws a large arc (or circle) that swells radially outward of the trunk portion 50 by centrifugal force, while expanding the diameter. Since it moves, it hardly touches the surface of the body part 50, or only makes a light contact with the surface of the body part 50 with a relatively small pressing force, and little or no frictional force is generated. The building frame member 6 falls smoothly. Since the pulley 90 is farther forward than the front surface of the bitty temporary scaffold 201 and the ring portion 5 of the descending rope 3a is pulled forward by the guide rope 211 via the carabiner 219, the building frame member being unloaded 6 and the front surface of the bite-type temporary scaffold 201, there is no risk of the building frame member 6 colliding with the front surface of the bity temporary scaffold 201, and there is less risk of being caught by the ring portion 7 of the ascending rope 3b. Become. Therefore, the worker A does not need to push the lowering rope 3a forward so that the building frame member 6 being unloaded does not collide with the front surface of the temporary temporary scaffold 201. It is only necessary to be careful not to catch the ring portion 7 on the building frame member 6 being unloaded, and workability is extremely good (see FIG. 42).

When the building frame member 6 approaches the ground, when the worker A grasps the ascending rope 3b with both hands or one hand wearing leather gloves and restrains the upward movement a little, the worker A is wound around the fixed body portion 50 of the brake portion 49. The unloading rope 3 is tightened to reduce the diameter, and is brought into contact with the surface of the body portion 50 with a large pressing force, so that a large frictional force is generated and a brake is applied. Thereby, the building frame member 6 can be slowly lowered to the ground without strongly grasping the ascending rope 3b.
The worker B on the ground removes the guide rope 211 from the carabiner 219 fitted to the ring portion 5 of the unloading rope 3, further removes the sling rope 221 from the carabiner 220, unloads the building frame member 6 from the unloading rope 3, and is free. What is necessary is just to pile up in a space (refer FIG. 43).
After one unloading, the worker A removes the ascending rope 3b of the unloading rope 3 from the brake portion 49, rotates the pulley 90 180 degrees around the hook neck, and descends with the ascending side of the unloading rope 3. After the sides are replaced (carabiners 223 and 224 are also fitted to the ring portion 7 and the slinging wire 225 is suspended on the carabiner 224), the same operation is repeated and another scaffold member (building) Unload frame members, scaffolding stage, etc.

When it is desired to change the installation location of the unloading assisting tool 240 to one level below the bitty-type temporary scaffold 201, the worker B on the ground removes the fixing of the heavy object 218 and the guide rope 211. The worker A on the uppermost stage of the bite-type temporary scaffold 201 hangs the ring part 5 (or ring part 7) on one end side of the unloading rope 3 on the rope hook part 159 (or 157) so as not to fall. The holding rope 216 is removed from the hanging rope hooks 214 and 215 (see FIG. 44). Then, the unloading aid 240 is removed from the building frame member 2 by removing the clamp 42 from the vertical frame 8 of the building frame member 2 and moving the base column 41 slightly upward to remove the hook 55 from the horizontal frame 4 ( (See FIG. 45). 46, the engaging claw 143 of the base column 41 is engaged with the front vertical frame 11 and the hook 55 is attached to the horizontal frame 23 of the building frame member 10 with respect to the building frame member 10 one step below. After fitting, the clamp 42 attached to the base column 41 may be fastened to the vertical frame 11 and replaced.
After that, leaving the building frame member 10, remove the scaffolding stages 24, 25 and other building frame members of the stage previously placed by the building frame member 2 and the worker A, and place them on the stage one stage below the stage unloaded last time. (See FIG. 47). Next, the unloading auxiliary tool 240 is suspended by suspending the suspension rope 216 passed through the carabiner 217 and temporarily fixing the suspension rope hooks 214 and 215 by winding them (see FIG. 48). In the same manner as described above, the scaffold member removed this time is lowered to the ground.

According to the third embodiment, the unloading assisting tool 240 detachably installed at the upper end of the front vertical frame 8 out of the building frame member 2 standing on the uppermost stage of the bite-type temporary scaffold 201 is used. Thus, the scaffold member can be unloaded smoothly without colliding with the front surface of the bitty temporary scaffold 201. Specifically, the operator B on the ground pulls the guide rope 211 hung from the front end of the unloading assisting tool 240 to near the ground, and fixes it to the heavy object 218 in a diagonally forward and downward direction. The worker A placed on the uppermost stage of the bitty temporary scaffold 201 puts unloading rope 3 on the pulley 90 suspended on the pulley mounting portion 46 near the front end of the unloading assisting tool 240 by putting leather gloves on both hands. Wind around the trunk portion 50 of the brake portion 49 for about ¼ to several turns. Further, the unloading rope 3 below the trunk portion 50 is wound around the rope hooks 158 and 159 (or 156 and 157) to temporarily restrain the movement. Then, both hands are separated from the unloading rope 3 and are unloaded via the sling wires 221 on the carabiner 220 fitted to the ring portion 5 on one end side of the descending rope 3a hanging from the pulley 90 on the uppermost stage. The building frame member 6 is suspended, and the building frame member 6 to be unloaded, which is suspended by the ring portion 5, is dropped forward. At this time, since the arm portion 245 is directed obliquely upward and the position of the pulley 90 is high, the scaffold stages 24 and 25 in which the lower end of the building frame member 6 suspended on the wheel portion 5 is arranged by the worker A are disposed. It becomes difficult to hit, and handling of the building frame member 6 becomes easy. Since the movement of the unloading rope 3 is restricted, the dropped building frame member 6 is suspended by the pulley 90 via the unloading rope 3 and has not yet been lowered. Next, the guide rope 211 is inserted and suspended in the other carabiner 219 fitted to the ring portion 5 of the descending rope 3a.
Next, remove the ascending rope 3b from the rope hooks 158 and 159 (or 156 and 157) and support it with hands wearing leather gloves so as not to restrain the ascending movement of the ascending rope 3b hanging from the brake part 49. The building frame member 6 is dropped on the ground. When the descent speed of the building frame member 6 increases, the unloading rope 3 wound around the trunk portion 50 draws a large arc (or circle) swelled radially outward by centrifugal force, and moves while expanding in diameter. The frame 50 is hardly in contact with the surface of the portion 50 or only lightly contacts the surface of the body portion 50 with a relatively small pressing force. The member 6 falls. Since the pulley 90 is separated forward from the front surface of the bite-type temporary scaffold 201 and the ring portion 5 of the descending rope 3a on which the building frame member 6 is suspended is pulled forward by the guide rope 211, the unloading is being performed. There is a large distance between the building frame member 6 and the front surface of the bite-type temporary scaffold 201, so that the building frame member 6 does not collide with the front surface of the bity-type temporary scaffold 201 and is less likely to be caught by the ring portion 7. Become. Therefore, the worker A does not need to push the lowering rope 3a forward so that the building frame member 6 being unloaded does not collide with the front surface of the bitty temporary scaffold 201, and the lower end of the lower end is controlled by hand. It is only necessary to take care that the ring portion 7 is not caught by the building frame member 6 being unloaded, and workability is extremely good.

When the building frame member 6 comes close to the ground, the lower side rope 3b on the lower side of the trunk portion 50 is grasped with both hands or one hand wearing leather gloves, and the upward movement is restrained a little. Then, the unloading rope 3 wound around the brake part 49 is tightened to reduce the diameter, and a large frictional force is generated by contacting the surface of the body part 50 with a large pressing force, and the brake is applied. Thereby, the building frame member 6 can be slowly lowered to the ground without strongly grasping the ascending rope 3b.
Accordingly, the physical burden on the worker A is reduced, the frictional heat between the leather gloves and the ascending rope 3a is small, there is no risk of burns, and work interruptions and delays are unlikely to occur and workability is improved. Moreover, the leather gloves are less damaged and economical. Moreover, since only a leather glove should just fit in a hand, it does not become thick but this also improves workability | operativity. Further, since it is not necessary to hold both the descending rope 3a and the ascending rope 3b together when the brake is applied, the risk of the ascending rope 3b being caught by the building frame member 6 to be unloaded is reduced.
The unloading assisting tool 240 is installed on the building frame member 2 by engaging the engaging claws 143 of the base column 41 with the front vertical frame 8 and fitting the hook 55 with the horizontal frame 4. It is only necessary to fasten it to the vertical frame 8 by the clamp 42 attached to the, so that a simple operation is sufficient.
Further, by fitting the hook 55 fixed to the upper end of the base column 41 to the horizontal frame 4, even if the unloading assisting tool 240 tries to turn left and right, the hook 55 abuts against the horizontal frame 4 to prevent the turning. The direction can be fixed with a simple structure so that the unloading aid 240 does not turn carelessly.
Further, when a load of the unloading target member is applied to the unloading assisting tool 240, the building frame member 2 is easily inclined forward, but the arm portion 245 of the unloading assisting tool 240 is suspended by the suspension rope 216. Therefore, the building frame member 2 is prevented from being tilted forward and detached from the bite-type temporary scaffold 201.

In the third embodiment described above, an example is shown in which the arm portion extends obliquely upward in the forward direction. However, the present invention is not limited to this, and the arm portion may be extended horizontally in the forward direction. good.
Moreover, although the example which fixed the engaging claw to the lower part of the back side of a base support | pillar was given, you may replace an engaging claw with the same clamp as the upper part of a base support | pillar back side.
Moreover, you may make it provide a pair of rope hook part in the right-and-left both sides of a reinforcement member instead of providing in the right-and-left both sides of a base support | pillar.
Also, the upper rope hanging portion (reference numerals 156 and 158 in FIG. 39) is omitted, and only the lower rope hanging portion (reference numerals 157 and 159 in FIG. 39) is left, and among the unloading ropes wound around the trunk portion, The ascending movement may be temporarily constrained by winding the ascending rope on the lower side of the trunk part around the lower rope hook part and then winding it again on the trunk part.
Further, the hook for preventing turning may be omitted.
