As shown in FIG. 6, the bolt member 15 includes a shaft portion 15a provided with a thread groove and a bolt head 15b provided at the upper end of the shaft portion 15a in the drawing. Further, a pin hole 15c that penetrates the shaft portion 15a in the radial direction is provided at the lower end of the shaft portion 15a in the drawing. Here, the shaft portion 15a is formed to have a diameter smaller than the diameter of the insertion hole 14c provided in the bottom portion 14b of the outer cylinder 14, and the bolt head 15b is formed to have a diameter larger than the diameter of the insertion hole 14c.

As shown in FIG. 7, the inner cylinder 16 includes a tubular portion 16a having a square cross section and a nut portion 16b integrally connected to the upper end of the tubular portion 16a. Further, a stopper hole 16c into which a stopper 17 described later can be inserted is provided at the lower end of the tubular portion 16a. Further, near the upper end of the tubular portion 16a, a hole 16d that penetrates the tubular portion 16a in the radial direction is provided.

As shown in FIG. 8, the stopper 17 has a plate shape, and a retaining portion 17a larger than the stopper hole 16c is formed at the end thereof. Further, on the tip end side of the stopper 17, a receiving portion 17b that curves along the curvature of the outer circumference of the cross member 9b of the extension portion 9 and a rivet hole 17c that penetrates the receiving portion 17b are provided.

Then, as shown in FIG. 4A, the stopper 17 is inserted into the stopper hole 16c, and then the rivet 18 is inserted into the rivet hole 17c to plastically deform the rivet 18, so that the stopper 17 becomes the rivet 18. The retaining portion 17a and the retaining portion 17a are prevented from coming out of the stopper hole 16c. That is, in this example, the stopper 17 is slidably held in the stopper hole 16c of the inner cylinder 16.

Next, a method of assembling the column member 13 as the fixing mechanism will be described. First, the bolt member 15 is inserted from above into the insertion hole 14c provided in the bottom portion 14b of the outer cylinder 14. At this time, since the bolt head 15b of the bolt member 15 is formed larger than the insertion hole 14c, the bolt head 15b is caught by the bottom portion 14b of the outer cylinder 14 and is held by the outer cylinder 14.

After that, the inner cylinder 16 is inserted into the outer cylinder 14 from the lower side, which is the opposite bottom side of the outer cylinder 14, and the nut portion 16b of the inner cylinder 16 is inserted into the screw groove provided in the shaft portion 15a of the bolt member 15. By screwing, the inner cylinder 16 is screwed to the bolt member 15.

Further, as shown in FIG. 4A, the pin holes 15c provided at the lower end of the shaft portion 15a are provided with holes 14g in the cylinder portion 14a of the outer cylinder 14 and the cylinder portion 16a of the inner cylinder 16, respectively. , 16d, a pin 19 is inserted so that the inner cylinder 16 does not fall off from the bolt member 15.

Next, a method of attaching the fixed width bar 11 to the scaffolding body SB by the pillar member 13 as the fixing mechanism will be described. First, the hooks 14e of each fixing mechanism are hooked on the cross members 9b and 9b of the extension portion 9, and the fixing width bar 11 is temporarily fixed to the cross members 9b and 9b of the extension portion 9.

Here, the inner cylinder 16 is prevented from rotating with respect to the outer cylinder 14 by forming the tubular portion 16a of the inner cylinder 16 in a square cross section. Therefore, the bolt member 15 and the inner cylinder 16 form a feed screw mechanism, and when the bolt member 15 is rotated in the tightening direction, the inner cylinder 16 is shown in FIG. 4 (A) via the nut portion 16b. When the bolt member 15 is rotated in the upward direction and the bolt member 15 is rotated in the loosening direction, the inner cylinder 16 moves in the downward direction in FIG. 4A via the nut portion 16b. In this example, the cylinder portion 16a is formed into a square columnar cross section to prevent the inner cylinder 16 from rotating with respect to the outer cylinder 14, but the cylinder portion 16a may be prevented from rotating by other means.

Therefore, by sliding the stopper 17 held at the lower end of the inner cylinder 16, the bolt member 15 is tightened in the tightening direction with the receiving portion 17b facing the hook 14e as shown by the solid line in FIG. 4 (A). When rotated to, the stopper 17 is lifted by the feed screw mechanism, and the cross member 9b of the extension portion 9 can be sandwiched between the hook 14e and the stopper 17, so that the fixed width bar 11 can be firmly attached to the scaffolding body SB.

At this time, since the hook 14e and the receiving portion 17b of the stopper 17 are curved along the curvature of the cross member 9b, there is no concern that the fixed width bar 11 will move laterally and come off.

In this example, the fixed width bar 11 is attached to the extension portion 9 of the scaffolding main body SB, but when the extension portion 9 is omitted, the cross member 5b of the main body portion 7 is hooked 14e and a stopper. The fixed scaffold 11 may be attached to the main body 7 by being sandwiched between the 17 and the main body 7.

Next, a structure for attaching the width bar 3 between the plurality of scaffolding units S1 and S2 will be described in detail. As shown in FIG. 9, the skirting board 3 includes a rectangular skirting board main body 20 and mounting brackets 21 provided at both left and right ends of the skirting board main body 20 in the longitudinal direction.

Further, in this example, the width bar main body 20 is composed of two members, a large width tree 22 and a small width tree 23 formed to be one size smaller than the large width tree 22.

Specifically, the large timber 22 is rectangular and has bent portions 22a and 22b having an L-shaped cross section formed by being bent inward along the longitudinal direction at the upper end portion and the lower end portion. It is formed in a shape. Further, the small width tree 23 has the same shape as the large width tree 22 except that it is formed to be one size smaller than the large width tree 22, and the upper end portion and the lower end portion are inward along the longitudinal direction. The bent portions 23a and 23b having an L-shaped cross section formed by being bent are provided, and the bent portions 23a and 23b are formed in a U-shaped cross section.

Then, as shown in FIGS. 9 and 10, the small lumber 23 is slidably inserted into the large lumber 22, so that the lumber body 20 has a telescopic structure that can be expanded and contracted.

Further, in this example, as shown in FIGS. 9 and 10, a retaining metal fitting 30 is attached to the upper end side bent portion 22a of the large timber 22.

As shown in FIG. 11, the retaining metal fitting 30 connects the short plate portion 30a, the long plate portion 30b longer in the height direction than the short plate portion 30a, and one end of the short plate portion 30a and the long plate portion 30b. It is a member having a J-shaped cross section provided with a connecting plate 30c, and the short plate portion 30a is connected to the tip end portion of the upper end side bending portion 22a of the large width tree 22 by a rivet 31.

At this time, since the upper end side bending portion 22a of the large width tree 22 is formed longer than the upper end side bending portion 23a of the small width tree 23, the rivet 31 of the upper end side bending portion 22a of the large width tree 22 is inserted. There is no bent portion 23a on the upper end side of the small width timber 23 at the position where the rivet 31 is bent so as not to interfere with the small width tree 23.

Further, in this example, the plate 32 is attached to the left end of the small width tree 23, and even if the small width tree 23 moves significantly in the pull-out direction, which is the right direction in FIGS. Since the long plate portion 30b of the stopper 30 comes into contact with the plate 32, it is possible to prevent the narrow bar 23 from coming off.

Returning, as shown in FIG. 10, the mounting bracket 21 includes a swing bracket 24 having a U-shaped cross section composed of a vertical plate portion 24a and a pair of horizontal plate portions 24b extending horizontally from the upper and lower ends of the vertical plate portion 24a. The vertical plate portion 24a of the rocking metal fitting 24 is provided with a lock metal fitting 25 attached from the skirting board main body 20 side.

As shown in FIGS. 12A and 12B, bolt holes 24c and 24c are provided at the tips of the horizontal plate portions 24b and 24b of the rocking metal fitting 24, respectively, and the bolt holes 24c and 24c are shown in FIGS. 9. As shown in FIG. 10, the bolt 28 is inserted through the bent portion 22a, 22b (23a, 23b) with the nut 29 in a state of facing the holes (not shown) provided on the upper surface and the lower surface, respectively. By tightening from the opposite side, the rocking metal fitting 24 is connected to the widthpiece main body 20.

In this way, if the nut 29 is loosened, the rocking metal fitting 24 can swing back and forth with respect to the wallet body 20 with respect to the bolt 28, so that the mounting metal fitting 21 can swing back and forth with respect to the wallet body 20. Can be oscillated back and forth.

Further, as shown in FIGS. 12A and 12B, vertically long elongated holes 24d and two hook insertion holes 24e and 24f are arranged in series in the vertical plate portion 24a of the rocking metal fitting 24 in order from the top. It is provided.

As shown in FIGS. 13 (A) and 13 (B), the lock metal fitting 25 includes a plate-shaped main body portion 25a and a pair of protruding plates 25b provided at the upper left and right ends of the main body portion 25a in FIG. 13 (A). 25b is provided. Further, in the main body 25a, in order from the top, a round hole 25c having a length about half of the elongated hole 24d and a communication hole 25d having the same size as the hook insertion hole 24e are provided side by side in series.

Then, in this example, the lock metal fitting 25 is brought into contact with the surface of the vertical plate portion 24a of the rocking metal fitting 24 on the skirting body 20 side, and the bolt 26 is inserted with the elongated hole 24d and the round hole 25c facing each other. Then, by tightening with the nut 27 from the opposite side, the lock metal fitting 25 is connected to the rocking metal fitting 24 as shown in FIG.

At this time, the round hole 25c provided in the lock metal fitting 25 is formed to be shorter in the vertical direction than the elongated hole 24d provided in the rocking metal fitting 24. Therefore, if the nut 27 is loosened, the bolt 26 can be removed. It can move up and down along the elongated hole 24d. Therefore, the lock metal fitting 25 is connected to the rocking metal fitting 24 so as to be vertically movable.

However, instead of tightening the lock fitting 25 with the nut 27, simply prevent it from coming off, lift it manually when moving it upward, and release it when moving it downward by its own weight. You may let it fall.

Further, in this example, the width of the main body portion 25a of the lock fitting 25 is equal to the width of the vertical plate portion 24a of the swing fitting 24. Therefore, since the vertical plate portion 24a can be held between the protruding plates 25b and 25b provided at the left and right ends of the main body portion 25a, lateral positioning when fixing the lock metal fitting 25 to the rocking metal fitting 24 can be easily performed.

Next, a method of mounting the width bar 3 between the scaffolding units S1 and S2 via the mounting bracket 21 will be described. First, the lock metal fitting 25 is placed at a position where the upper and lower ends of the communication holes 25d provided in the lock metal fitting 25 connected to the rocking metal fitting 24 are aligned with the hook insertion hole 24e on the upper side of the rocking metal fitting 24. Fix to. In this state, the upwardly curved hook pieces 14f and 14f provided on the fixed width bars 11 of the scaffolding units S1 and S2 are connected in series with the swinging metal fitting 24 of the mounting metal fitting 21 as shown in FIG. 14 (A). It is inserted into the hook insertion holes 24e and 24f formed side by side, respectively.

After that, when the nut 27 is loosened and the lock fitting 25 is moved downward along the elongated hole 24d, as shown in FIG. 14B, the lock fitting 25 closes a part of the hook insertion hole 24e, so that the hook piece Even if the 14f moves to the left side in the drawing and tries to come off, the tip of the hook piece 14f curved upward is caught by the lock metal fitting 25, and the lock state is set so that the hook piece 14f is prevented from coming off.

By performing the same work on both the left and right sides of the scaffolding 3, the timber 3 according to the present embodiment is attached between the scaffolding units S1 and S2.

In this example, the upper hook piece 14f inserted into the upper hook insertion hole 24f is locked by the lock metal fitting 25, but the lower hook piece 14f inserted into the lower hook insertion hole 24f is locked. It may be locked by the lock metal fitting 25.

Hereinafter, the action and effect of the width bar 3 and the scaffolding device 1 according to the present embodiment will be described.

In the present embodiment, the skirting board 3 includes a rectangular skirting board body 20 and mounting brackets 21 provided at both ends of the skirting board body 20 in the longitudinal direction, and the mounting bracket 21 is attached to the skirting board body 20. On the other hand, it is oscillatingly connected back and forth.

In the scaffolding device 1 composed of a plurality of scaffolding units S1 and S2, when the outer surface of the structure A is a curved surface, the scaffolding units S1 and S2 are separated from each other according to the curvature of the outer surface. Since the mounting bracket 21 for attaching 3 to the scaffolding units S1 and S2 is swingable, the same width strip 3 can be used even when the curvature of the outer surface of the structure A is different.

In this example, the bolt-nut connection is adopted as a means for swingably connecting the mounting bracket 21 to the hinge body 20 in the front-rear direction, but the mounting bracket 21 may be swingably connected. For example, the means is not particularly limited, and for example, a hinge may be used.

Further, in the present embodiment, the bracelet main body 20 is formed in a telescopic structure and can be expanded and contracted.

According to this configuration, in addition to the mounting bracket 21 being swingable back and forth, the skirting body 20 can be expanded and contracted, so that the skirting tool 3 can follow the curvature of the outer surface of the structure A. In addition, the drawstring 3 can also be used for structures A of more various shapes.

In this example, the main body 20 is composed of a large width tree 22 having a U-shaped cross section and a small width tree 23 that is one size smaller than the large width tree 22, and the small width tree 23 is the large width tree 22. By sliding inside, the skirting board body 20 can be expanded and contracted, but if the skirting board body 20 has a telescopic structure, the shape is not particularly limited, for example, the large skirting board 22 and the small skirting tree. The 23 may be formed into a square cross section so that the small timber 23 slides in the large timber 22.

Further, in the scaffolding device 1 according to the present embodiment, the scaffolding units S1 and S2 include a scaffolding body SB and a fixed width bar 11 rising from the structure A side of the scaffolding body SB, and the fixed width tree 11 is rectangular. The fixed scaffold main body 12 and a pair of pillar members 13 fixed to both ends of the fixed scaffold main body 12 in the longitudinal direction are provided, and the scaffold 3 can be attached to the pillar member 13 via the mounting bracket 21. ing.

According to this configuration, since the width bar 3 is attached to the pillar member 13 of the fixed width bar 11, the structure for attaching the width bar 3 between the scaffolding units S1 and S2 is simplified.

Further, in the scaffolding device 1 according to the present embodiment, the pillar member 13 has an upwardly curved hook piece 14f protruding from the outer outer surface of the outer periphery, and the mounting bracket 21 is moved back and forth with respect to the skirting body 20. A rocking metal fitting 24 that is swingably connected and has a vertically long elongated hole 24d and a hook insertion hole 24e arranged side by side, and a round hole 25c that is shorter in the vertical direction than the elongated hole 24d. The communication holes 25d are provided side by side in series, and the round holes 25c and the elongated holes 24d of the swing metal fitting 24 are connected to the rocking metal fitting 24 so as to be vertically movable by a bolt 26 inserted in a state of facing each other. When the lock metal fitting 25 is provided and the hook piece 14f is inserted through the hook insertion hole 24e and the communication hole 25d and the lock metal fitting 25 is moved downward, the hook piece 14f is locked and the scaffold 3 is opened. It can be attached to the fixed width bar 11.

In this example, the vertical length of the round hole 25c is about half the length of the long hole 24d, but if it is shorter than the long hole 24d, the lock metal fitting 25 can be moved up and down, so that the long hole is long. The vertical lengths of the 24d and the round hole 25c may be appropriately set according to the distance to which the lock metal fitting 25 is moved.

Further, in the scaffolding device 1 according to the present embodiment, the pillar member 13 has a fixing mechanism for fixing the fixed width bar 11 to the scaffolding body SB, and the fixing mechanism has a hook 14e curved downward on the outer circumference of the lower end. The inner cylinder is provided with the formed outer cylinder 14, the bolt member 15 inserted into the outer cylinder 14 from above, and the inner cylinder 16 which is screwed into the thread groove of the bolt member 15 and can be moved in the axial direction. The 16 is prevented from rotating with respect to the outer cylinder 14, and a stopper 17 facing the hook 14e is provided at the lower end of the inner cylinder 16.

According to this configuration, by rotating the bolt member 15, the inner cylinder 16 having the stopper 17 moves in the axial direction. Therefore, if the inner cylinder 16 is moved upward, it is sandwiched between the stopper 17 and the hook 14e. Can be done. Therefore, the fixed timber 11 can be fixed more firmly than simply hooking the fixed timber with only the hook 14e and fixing it to the scaffolding body SB. Further, in this example, since the width bar 3 is attached to the fixed width bar 11, if the fixed width tree 11 is firmly fixed, it is also advantageous in that the width tree 3 is hard to come off.

Further, in this example, since the stopper 17 is slidably held at the lower end of the inner cylinder 16, when fixing the fixed width bar 11 to the scaffolding body SB, it is only necessary to slide the stopper 17 for work. Sex improves. However, the stopper 17 may be inserted later without being held at the lower end of the inner cylinder 16.

Although the preferred embodiments of the present invention have been described in detail above, it is natural that modifications, modifications and changes can be made without departing from the scope of claims.
