Description

  The present invention relates to a scaffold structure installed on a side part of a building such as a house or a building or a structure such as a ship, and particularly relates to a scaffold auxiliary member for improving safety.

  FIG. 6 is a partial perspective view for explaining a conventional scaffold structure installed on a side of a structure such as a building or a ship.

  As shown in the figure, a large number of inner struts 1a and outer struts 1b are erected at predetermined intervals on the outer periphery of a structure (not shown), and each inner strut 1a and outer strut 1b A pipe-shaped handrail 2a is installed between them. And between the handrail 2a and the handrail 2a, the scaffold board 4 which attached the hooks 3 and 3 integrally to both ends is constructed. A pipe-shaped handrail 2b is also installed between the outer support column 1b and the outer support column 1b.

  An operator stands on the scaffold plate 4 of the scaffold structure assembled in this way and performs a predetermined operation or moves on the scaffold plate 4.

  However, in the scaffold structure shown in FIG. 6, no safety measures are taken between the inner support column 1a and the inner support column 1a, or between the outer support column 1b and the outer support column 1b. The foot is slid to drop downward from between the outer support column 1b and the outer support column 1b, or a building member placed on the scaffolding plate 4 is applied with some external force from between the outer support column 1b and the outer support column 1b. There was an accident that dropped down.

  In order to prevent such an accident, the structure of a scaffold structure as shown in FIG. 7 can be considered. As shown in the figure, this scaffold structure has a configuration in which a plate-like skirting board 5 similar to the scaffold plate 4 is applied between the outer support column 1b and the outer support column 1b and fixed by a wire. The hooks 3 and 3 are integrally attached to both ends of the skirting board 5, and the skirting board 5 is positioned between the outer support column 1b and the outer support column 1b by the hooks 3 and 3, and the outer support column 1b is not shown. The ends of the skirting board 5 are fastened by a wire or the like.

  Thus, by installing the skirting board 5 between the outer support column 1b and the outer support column 1b, it is possible to prevent a fall accident from between the outer support column 1b and the outer support column 1b to some extent, but there is no problem. .

  That is, in the structure in which the baseboard 5 is inserted and attached between the outer support column 1b and the outer support column 1b as in this scaffold structure, the lateral width of the scaffold plate 4 is the same as that of the inner support column 1a and the outer support column 1b as shown in FIG. If it is narrower than the interval, a gap 6 having the same length as the interval between the outer column 1b and the outer column 1b is formed between the scaffold plate 4 and the skirting board 5. Then, there is a risk that a building member or the like falls downward from the gap 6 or a worker plunges into the gap 6 to cause an unexpected accident, which is still insufficient in terms of safety. .

  Further, since the upper and lower ends of the baseboard 5 are fixed to the outer support column 1b by a number line or the like, when the scaffold structure is disassembled, the number line becomes a waste material and cannot be reused. In addition, there is a problem that a large amount of wire scraps are produced and the processing is complicated.

  An object of the present invention is to provide a scaffolding auxiliary member that eliminates the disadvantages of the prior art, has higher safety, and is convenient for handling such as storage and transportation, and a scaffold structure using the same. .

In order to achieve the above object, the first means of the present invention is a scaffolding auxiliary member,
A standing plate member that is erected between adjacent struts and fixed to the struts;
A blocking member placed on the scaffolding plate and closing a gap formed between the scaffolding plate and the column;
The closing member is foldably connected to the standing plate member.

According to a second means of the present invention, in the first means,
The closing member is rotatably connected to the standing plate member, and restricts the rotation angle of the closing member so that the closing member does not rotate about 270 degrees or more with respect to the standing plate member. The rotation angle restricting means is provided.

A third means of the present invention is the first or second means,
A fastening member that holds the folded state of the standing plate member and the closing member is attached to the standing plate member or the closing member.

The fourth means of the present invention is:
The inner support column and the outer support column are paired, and a large number of the support column pairs are set up at a predetermined interval. In the scaffold structure in which the scaffold plate is built,
A scaffolding auxiliary member of any one of the first to third means is installed from the support column to the scaffolding plate.

According to a fifth means of the present invention, in the fourth means,
A bolt insertion hole is formed in the standing plate member of the scaffolding auxiliary member, a clamp with a bolt is fixed to the support column, and a bolt of the clamp with bolt is inserted into the bolt insertion hole to fix the standing plate member to the support column. It is characterized by doing.

  In the present invention, as described above, the space between the adjacent struts and the struts is blocked by the standing plate member, and the gap formed between the struts and the scaffolding plate is blocked by the blocking member. It is possible to prevent accidents of dropping workers and members in the vicinity of the machine and to ensure high safety.

  Further, since the closing member and the standing plate member are connected so as to be foldable, they become compact without being bulky during handling such as storage and transportation, and thus a scaffolding auxiliary member convenient for storage and handling can be provided.

The side part fall prevention member 7 according to the embodiment of the present invention is installed from the outer support column 1b to the one side end part 4a of the scaffold plate 4 as shown in FIGS.
As shown in FIGS. 1 to 3, the side fall prevention member 7 includes a standing plate member 8 erected between the outer column 1b and the outer column 1b, and the outer column 1b and the scaffold shown in FIGS. And a closing member 9 that closes the gap 6 formed between the one end portions 4a of the plate 4. The upright plate member 8 and the closing member 9 are connected by a hinge 10 and can be folded as shown in FIG. 1, and the closing member 9 is about 270 degrees (about 3 / 4 rotations).

  A stopper 11 having substantially the same length as that of the closing member 9 is integrally provided at an end portion adjacent to the hinge 10 of the closing member 9 by welding or the like. As shown in FIG. 2, when the closing member 9 is rotated about 270 degrees (about 3/4 round) with respect to the standing plate member 8, the end surface 12 of the stopper 11 comes into contact with the side surface of the standing plate member 8, The closing member 9 is prevented from rotating further.

  As shown in FIG. 3, the horizontal length L1 of the upright plate member 8 is designed to be slightly longer than the distance L2 between the outer support column 1b and the outer support column 1b (L1> L2). The parts are superposed and attached to one outer support 1b.

  A bolted clamp 13 is used to attach the upright plate member 8 to the outer support column 1b. As shown in FIGS. 2 and 3, the bolted clamp 13 is fixed to a predetermined position of the outer support 1b, and the bolt of the bolted clamp 13 is inserted into a bolt insertion hole (not shown) formed in the standing plate member 8. By inserting 14 and fastening with the nut 15, the side portion fall prevention member 7 (standing plate member 8) is attached to the outer column 1 b.

  As shown in FIG. 1, the height H of the standing plate member 8 and the closing member 9 is designed to be substantially the same size, and the actual height H is set to 15 cm or more in consideration of safety. Fastening members 16 made of an elastic metal plate or the like are provided on both sides of the upper end portion of the upright plate member 8.

  As shown in FIG. 5, an end portion fall prevention member 17 is attached to the end portion of the scaffold structure from the inner support column 1a to the outer support column 1b. The end drop prevention member 17 has a U-shaped planar shape, and is provided so that the end plate portion 18 extending from the inner support column 1a to the outer support column 1b and both end portions of the end plate portion 18 face each other inward. Mounting plate portions 19, 19. The mounting plate portion 19 is connected to the end plate portion 18 via a hinge 21 so as to be foldable.

  As shown in FIG. 4, bolt insertion holes 20 are respectively formed at predetermined positions of the mounting plate portions 19 and 19. As shown in FIG. 5, one of the end drop prevention members 17 is directly attached to the inner support 1a by the bolted clamp 13 via the mounting plate 19, and the other end drop prevention member 17 is attached The plate portion 19 is superimposed on the end portion of the upright plate member 8 of the side portion fall prevention member 7 and attached to the outer support column 1b by a single bolted clamp 13.

  As shown in FIG. 5, normally, since a very large gap is not formed between the handrail 2 and the scaffolding plate 4, the end portion fall prevention member 17 does not need a closed portion to close the gap, but the gap is not In the case of being large, it is also possible to integrally provide a closed portion at the lower end of the end plate portion 18 by bending and close the gap with the closed portion.

  When the side fall prevention member 7 is stored or transported, as shown in FIG. 1, the standing plate member 8 and the closing member 9 are folded and overlapped, and the state is held by the fastening member 16. Thus, since the side part fall prevention member 7 is foldable, it is not bulky and is convenient for storage and transportation of the side part fall prevention member 7.

  When the side fall prevention member 7 is attached to the scaffold structure, the closing member 9 is removed from the fastening member 16 from the state shown in FIG. 1 and rotated by about 270 degrees as indicated by the arrow so that the closing member 9 is in a horizontal state. To. In this state, as shown in FIG. 2, the closing member 9 is placed on one side end 4a of the scaffolding plate 4 to close the gap 6, and the standing plate member is clamped with the bolted clamp 13 fixed in advance to the outer column 1b. By fastening 8 to the outer support column 1b, the attachment of the side drop prevention member 7 is completed.

  Since the end surface 12 of the stopper 11 of the closing member 9 is in contact with the side surface of the standing plate member 8 with the side fall prevention member 7 attached in this way, the free end 9a of the closing member 9 is in the direction indicated by the arrow X. The blocking member 9 is securely placed on the scaffold plate 4. Since the floating of the blocking member 9 is prevented in this way, it is not necessary to fix the blocking member 9 to the scaffold plate 4 with a wire or the like, the installation of the side fall prevention member 7 is simple, and the scaffold structure is disassembled. Sometimes the amount of wire scrap generated can be reduced.

  When there is almost no gap 6 between the outer support 1b and the scaffolding plate 4, the side fall prevention member 7 is folded without opening the closing member 9 as shown in FIG. Attaching to the outer wall 1b helps to prevent the outer column 1b from falling.

  The side fall prevention member 7 and the end fall prevention member 17 must have a predetermined rigidity, and are a metal plate, a mesh-like member such as the scaffold plate 4, or a punching metal or an expanded plate having a large number of small holes. It can be composed of metal or the like. By configuring the side part fall prevention member 7 and the end part fall prevention member 17 with a mesh member, a punching metal, an expanded metal, or the like, the weight can be reduced.

In the above-described embodiment, the separate stopper 11 is attached to the closing member 9, but a part of the closing member 9 may be cut and raised, and the cut-and-raised portion may be a stopper that contacts the side surface of the standing plate member 8. It is also possible to use a hinge with a stopper function that restricts the rotation angle of the closing member 9 within the aforementioned range.
It is also possible to attach a slip prevention member to the surface of the closing member 9.

  In the above embodiment, the side fall prevention member 7 is provided between the outer support column 1 b and the scaffold plate 4, but the side fall prevention member 7 may be provided between the inner support column 1 a and the scaffold plate 4.

The effects according to the claims are as follows.
According to the first aspect of the present invention, the space between the adjacent column and the column is blocked by the standing plate member, and the gap formed between the column and the scaffolding plate is blocked by the blocking member. In addition, it is possible to prevent an operator or member from dropping accidents around the scaffolding board, and to ensure high safety.

  Further, since the closing member and the standing plate member are connected so as to be foldable, they become compact without being bulky during handling such as storage and transportation, and thus a scaffolding auxiliary member convenient for storage and handling can be provided.

  According to the second aspect of the present invention, the rotation angle restricting means such as a stopper is provided for restricting the rotation angle of the closing member so that the closing member does not rotate about 270 degrees or more with respect to the standing plate member.

  Therefore, the free end side of the closing member is prevented from floating, and the closing member is reliably placed on the scaffold plate. Since the lifting of the blocking member is prevented in this way, it is not necessary to fix the blocking member to the scaffolding plate with a wire or the like, the installation of the scaffolding auxiliary member is simple, and the amount of wire scrap generated when the scaffold structure is disassembled Can be reduced.

  According to the third aspect of the present invention, since the fastening member that holds the folded state of the standing plate member and the closing member is attached, there is no gap having a safety problem between the support column and the scaffold plate. In the case of the scaffold structure, the standing plate member and the closing member can be folded and fixed to the support column, and the scaffold auxiliary member does not get in the way.

  According to invention of Claim 4, a highly safe scaffold structure can be provided.

  According to the fifth aspect of the present invention, since the scaffolding auxiliary member can be fixed to the support pillar without using the number wire by using the clamp, the amount of the number of wire number waste generated when the scaffold structure is disassembled is reduced. In addition, the running cost can be reduced.

  In addition, it is conceivable to integrate the scaffolding auxiliary member and the clamp, but since the useful life is different between the scaffolding auxiliary member and the clamp, for example, the clamp part has reached the useful life, while the scaffolding auxiliary part is durable. Even when the lifetime has not been reached, a situation occurs in which the integrated scaffold auxiliary member and clamp must be discarded. On the other hand, by using the scaffolding assisting member and the clamp separately, the scaffolding assisting member and the clamp can be fully used up to their useful life, and as a result, the running cost can be reduced.
