Description

  The present invention relates to a scaffold lid member for closing a passage opening formed through a hierarchy in a scaffold device constructed in a hierarchy in the vertical direction.

  2. Description of the Related Art Conventionally, a scaffold device constructed when building a high-rise building or the like is constructed in a hierarchy with scaffold plates arranged in a horizontal direction spaced vertically.

  Therefore, the worker can perform a predetermined work on the scaffolding plate corresponding to the hierarchy, but the scaffold device has a passage opening formed through the hierarchy by removing the scaffolding plates corresponding to the upper and lower parts of the hierarchy. Yes. Such a passage opening is used as a space for arranging a desired pipe or the like in the building after the building frame is built, and facilitates the piping work. Moreover, before performing piping, a passage opening is utilized for an operator to go up and down the upper and lower levels. However, if the passage opening is left open, there is a risk that the operator may fall, so that the passage opening is normally covered with a lid member so as to be freely opened and closed.

  The lid member that covers the passage opening can be appropriately prepared by cutting the scaffold plate into a predetermined size, but in that case, the lid member and the scaffold plate are similar in appearance to each other in the lid state. Therefore, it is difficult for the operator to recognize where the lid member is, which is extremely inconvenient. If the lid member is not installed correctly and is installed in a state where a part of the passage opening is opened, there is a risk that the operator may step on the foot, which is extremely dangerous.

  In this regard, the present inventors, if the lid member is formed of a mesh plate having a number of eye holes, when the worker walks on the scaffold plate, the lower space is visually recognized through the eye holes, Since it was easy to recognize that a passage opening was formed in the part, it was noticed that it was safe. Moreover, with such a mesh plate, it is possible to illuminate through the upper and lower levels with a lighting device such as a projector even at night or in a dark place, so that the work is safe and the entry of suspicious persons and the like is prevented. There is an advantage that you can.

  By the way, as the mesh plate forming the lid member, for example, a punching metal plate can be used according to the above-mentioned purpose. However, in order to maximize the translucency, the mesh plate is used. It is preferable to use an expanded metal plate formed into a shape. The expanded metal plate is a metal plate that has been stretched so as to widen the slit in a state in which a large number of slits are formed. Since the lattice portion forming the mesh forms a rib with the edges directed to the surface, the operator's foot is difficult to slip and is optimal as a scaffolding lid member that requires safety.

  However, since the expanded metal plate is formed by extending so as to widen the slit, the end portions of the ribs described above are arranged in a protruding manner on at least a pair of opposing edges. For this reason, there is a risk of injury if the edges where the ends of the ribs are arranged are gripped with bare hands. In particular, in the case of a lid member for a scaffold, such a risk is particularly worrisome because it is necessary to open and close the lid member every time an operator goes back and forth through a passage opening.

  The present invention provides a lid member for a scaffold that solves the above-mentioned problems, and as a first means, a scaffold plate arranged in a horizontal direction is arranged in a layered manner with a space in the vertical direction. In the constructed scaffold device, a scaffold lid member for closing a passage opening formed through a hierarchy by removing the scaffold plates corresponding to the upper and lower sides, and the lid member is a substantially rectangular metal having a plurality of eye holes. A belt-shaped protective material is provided along at least a pair of opposing edges of the mesh plate, and the belt-shaped protective material has a decorative sheet and an adhesive layer on the front and back surfaces of the thick elastic sheet, respectively. Are laminated and integrated, and the edge of the mesh plate is formed by a front sheet portion and a back sheet portion formed in a substantially U-shaped cross-section by half-folding the band-shaped protective material at an approximately central portion in the width direction with the adhesive layer inside. Cover the part Together lies in that formed by adhesive fixing through the needle eye to each other adhesive layer of the front sheet section and the back sheet portion.

  In addition, the present invention is configured as a second means in a scaffold device constructed in a hierarchical manner with scaffold plates arranged in a horizontal direction spaced apart in the vertical direction, excluding the scaffold plates corresponding to the top and bottom. Expanded metal plate formed by stretching a metal plate provided with a large number of slits so that the slits are widened. The lattice ribs constituting a number of eye holes are formed by mesh plates having protrusions arranged on a pair of opposite edges of the plate, and at least the pair of edges of the mesh plate. A band-shaped protective material is provided along the surface of the thick elastic sheet, and a decorative sheet and an adhesive material layer are laminated and integrated on the front and back surfaces of the thick elastic sheet, respectively. Adhesive layer Cover the edges of the mesh plate with the front sheet part and the back sheet part formed in a U-shaped cross-section by half-folding inward and open the adhesive material layers of the front sheet part and the back sheet part to each other It is in the point which adheres and adheres through.

  According to the present invention, the lid member 5 is formed by a mesh plate 7 having a large number of eye holes 6. Therefore, when the worker walks on the scaffolding board, the user can visually recognize the lower space through the eye hole 6 and easily recognize that the passage opening 4 is formed in that portion. Work safety can be guaranteed. In addition, the eye opening 6 of the lid member 5 enables illumination through the upper and lower layers S by a lighting device such as a projector even at night or in a dark place, so that work safety and prevention of intrusion of suspicious persons and the like can be achieved. Also useful.

  And according to this invention which formed the cover member 5 with the expanded metal board 8, not only can improve the said effect by making translucency best, but it is suitable for the cover member for scaffolding because it is high in strength. In addition, since the ribs 9 constituting the lattice portion have the edges directed to the surface, the operator's feet are difficult to slip and work safety can be guaranteed.

  And this invention has provided the strip | belt-shaped protection material 10 along at least a pair of edge part of the mesh board 7. As shown in FIG. Therefore, when the lid member 5 is formed of the expanded metal plate 8, the end portions 9a of the ribs 9 forming the lattice portion are arranged in a protruding manner on at least a pair of opposing edges of the plate and are gripped with bare hands. Then, since there is a risk of injury, these projecting rib ends 9a are covered with the band-shaped protective material 10, which is safe.

  In particular, according to the present invention, the band-shaped protective material 10 is configured such that the decorative sheet 12 and the adhesive layer 13 are laminated and integrated on the front and back surfaces of the thick elastic sheet 11, respectively. The edge portion of the mesh plate 7 is covered with the front sheet portion 10a and the back sheet portion 10b formed in a substantially U-shaped cross-section by half-folding with the adhesive material layer 13 inside in the substantially central direction, and the front sheet portion The adhesive material layers 10 a and the back sheet portion 10 b are adhered and fixed to each other through the eye holes 6. Accordingly, the band-shaped protective material 10 abuts against the opening edge of the passage opening 4 in a state where the passage opening 4 is covered with the lid member 5, and the metal mesh plate 7 is elastically supported by the thick elastic sheet 10. When the person steps on the lid member 5, the lid member 5 does not sway but rather fits elastically so as not to move, and the edges of the mesh plate 7 generate noise such as rattling noise. There is nothing. Moreover, even when the operator grips the lid member 5 to open and close the passage opening 4, the rib end covered with the elastic sheet 11 is comfortable because it has elasticity, even if it is strongly gripped. 9a does not pierce the band-shaped protective material 10 and penetrates, and safety is high.

  Furthermore, since the decorative sheet 12 is integrated on the surface, for example, a warning display consisting of yellow and black stripes is given to the decorative sheet 12, and the position of the passage opening 4 due to the presence of the lid member 5 is conspicuous. By doing so, it is possible to ensure work safety and improve work efficiency to move up and down.

  And the strip | belt-shaped protection material 10 can be easily attached with respect to the cover member 5 by the adhesive material layer 13, Especially, the adhesive material layer 13 of the front sheet | seat part 10a and the back sheet | seat part 10b is mutually connected to the opening 6. Therefore, the adhesive strength is high and there is no fear of dropping off, and it can withstand long-term use.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows one layer portion of a scaffold device constructed in a hierarchy, and a number of scaffold plates 2 are arranged in a row in a beam 1 installed on a support column (not shown), thereby forming a layer S. Such a hierarchy S is constructed with an interval in the vertical direction. Therefore, the opening 4 of the passage 3 is formed through the upper and lower layers S by the space in which the scaffold plate 2 corresponding to the upper and lower sides is not provided. Such a passage 3 is a passage space for arranging a desired pipe or the like in the building after a building frame is built, and facilitates piping work. Further, before piping, the passage opening 4 is used by the worker to ascend and descend the upper and lower levels S. Therefore, the passage opening 4 is normally covered with a lid member 5 so as to be opened and closed. Therefore, an operator goes back and forth on the scaffolding plate 2 and the lid member 5.

  As shown in FIGS. 2 and 3, the lid member 5 is constituted by a substantially rectangular metal mesh plate 7 having a large number of eye holes 6, and the mesh plate 7 is preferably provided with a large number of slits. The expanded metal plate 8 is formed in a mesh shape by stretching the metal plate so that the slits are expanded. Such an expanded metal plate 8 is excellent in translucency and high in strength, and the lattice portion forming the mesh forms ribs 9 with the edges facing the surface. The person's feet are difficult to slip.

The lid member 5 is formed in a substantially rectangular shape by an expanded metal plate 8 so as to cover the passage opening 4 so as to be freely opened and closed. At this time, the end portions 9a of the lattice-like ribs 9 constituting a number of eye holes 6 are formed on the plate. Although a pair of edge portions facing each other are arranged in a protruding shape, a band-shaped protective material 10 is provided along at least the pair of edge portions.

  As shown in FIG. 4 (A), the band-shaped protective material 10 is obtained by laminating and integrating a decorative sheet 12 and an adhesive material layer 13 on the front and back surfaces of a thick elastic sheet 11, respectively. Used by cutting to length. In addition, the decorative sheet 12 of the belt-shaped protective material 10 has, for example, a yellow and black stripe pattern, or, in the case of a single color, a vermilion or yellow with a conspicuous color tone, so that a visual warning notice is displayed. Constitute.

  When attaching the band-shaped protective material 10 to the edge of the mesh plate 7 such as the expanded metal plate 8, as shown in FIG. 4 (B), the band-shaped protective material 10 is provided with the adhesive layer 13 at the substantially central portion in the width direction. The edge portion of the mesh plate 7 is covered with the front sheet portion 10a and the back sheet portion 10b formed in a substantially U-shaped cross-section by half-folding inward, and the adhesive layer of the front sheet portion 10a and the back sheet portion 10b 13 are adhered and fixed to each other through the eye holes.

  If the passage opening 4 of the scaffold device is covered with the lid member 5 of the present invention, there is no danger of the operator falling from the passage opening 4, and the work can be performed safely. At this time, since the lid member 5 is formed by a mesh plate 7 such as an expanded metal plate 8 having a large number of eye holes 6, when the worker walks on the scaffolding plate, the lid member 5 moves downward through the eye holes 6. Visualize the space. Moreover, the decorative sheet 12 of the band-shaped protective material 10 attached to the lid member 5 is provided with a warning display such as a yellow and black stripe pattern. Accordingly, the position of the passage opening 4 due to the presence of the lid member 5 is conspicuous, and the operator is alerted to recognize that the passage opening 4 is formed in that portion. Further, the eye hole 6 enables illumination through the upper and lower layers S by a lighting device such as a projector even at night or in a dark place.

  And if the lid member 5 is formed of the expanded metal plate 8, it is light in weight but high in strength, can withstand the load of the operator, and the rib 9 has the edge facing the surface, The person's feet are difficult to slip, and work safety is guaranteed.

  At this time, the cover member 5 is provided with the band-shaped protective material 10 provided with the thick elastic sheet 11, so that the band-shaped protective material 10 is opened to the passage opening 4 in the state where the passage opening 4 is covered by the cover member 5. The mesh plate 7 is elastically supported by the thick elastic sheet 10 in contact with the edge. Therefore, when the operator steps on the lid member 5, the lid member 5 does not sway but rather adheres elastically so as not to move, and the edge of the mesh plate 7 has a noise such as rattling noise. Will not occur.

  By the way, when an operator goes back and forth between the upper and lower levels S, it is necessary to open the passage opening 4 by removing the lid member 5. At this time, the operator holds the belt-shaped protective material 10 as a handle. Therefore, the lid member 5 may be lifted. As described above, when the lid member 5 is formed of the expanded metal plate 8, when the end portions 9a of the rib 9 are arranged in a protruding manner on at least a pair of opposite edges of the plate, Although there is a risk of injury, since these protruding rib ends 9a are covered with the band-shaped protective material 10, there is no such risk. In addition, since the band-shaped protective material 10 has elasticity, the feel at the time of gripping is good. Even if the band-shaped protective material 10 is strongly gripped, the rib end 9a covered with the elastic sheet 11 pierces the band-shaped protective material 10. It is safe because it never penetrates.

   Even when the lid member 5 is frequently lifted, the band-shaped protective material 10 directly adheres and adheres the adhesive material layers 13 of the front sheet portion 10a and the back sheet portion 10b to each other through the eye holes 6. As a result, it has a high adhesive strength and is not likely to fall off, and can withstand long-term use.
