Description

Technical Field

[0001] The present invention relates to the structure of the scaffold board of a scaffold used in construction work such as the construction, renovation, and demolition of buildings, and particularly relates to the scaffold board structure of a scaffold that can improve the efficiency of loading into the site, unloading from the site, installation at the site, and demolition.

Background Art

[0002] When performing construction work such as the construction, renovation, and demolition of buildings such as houses and buildings, in order to ensure the safety of workers working at heights and prevent accidents such as the falling of materials and tools, various scaffolds are installed around the building.

[0003] An example of this type of scaffold is described in Patent Document 1. This scaffold arranges a pair of columns at a predetermined interval in the direction between beams (building direction), and arranges a plurality of sets of this pair of columns at a predetermined interval in the direction of the girder row (direction along the building). Each pair of columns in each set is supported on the ground by a jack, a cross member is installed in the direction between beams of each pair of columns in each set, vertical members are installed between the outer columns and the inner columns adjacent in the direction of the girder row, respectively, and tread boards are installed between the cross members adjacent in the direction of the girder row. Width timbers facing the direction of the girder row are respectively attached to both ends in the direction between beams of each tread board.

[0004] In a scaffold with such a structure, the width timber is composed of a width timber body having a rectangular shape with a large slenderness ratio and locking fittings respectively attached to both longitudinal ends of the width timber body. By locking the locking portions of the pair of fitting pieces of this locking fitting to a pair of cross members in the direction of the girder row, width timbers are respectively attached to both ends in the direction between beams of the tread board. Further, both ends in the width direction of the width timber are bent in the same direction to form flange portions, and the bending strength of the width timber is increased by these flange portions.

[0005] Patent Document 2 describes another example of scaffolding. This scaffolding is constructed by bending both ends of the scaffolding board body in the width direction toward the downward side in a U shape, thereby forming a U-shaped left side plate and a U-shaped right side plate at both ends in the width direction, consisting of an outer upright plate, a downward curved side plate, and an inner upright plate, respectively. Furthermore, a cover with a U-shaped cross-section is attached to both ends of the scaffolding board body in the longitudinal direction, and a plurality of stiffening members are attached to the back side of the scaffolding body at predetermined intervals in the longitudinal direction.

[0006] By using scaffolding planks with this configuration, the rigidity of the planks can be increased, and workers can be prevented from being injured by the ends of the planks during the transportation of scaffolding components to and from the site, installation, and dismantling, thereby ensuring worker safety. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2017-201097 [Patent Document 2] Utility Model Registration No. 3220072 Publication [Overview of the project] [Problems that the invention aims to solve]

[0008] By the way, in the scaffolding described in Patent Document 1, since the treads and baseboards are formed separately, when transporting the scaffolding components from a material storage area to the construction site or from the site by truck, the treads and baseboards must be packaged separately and loaded onto the truck bed. This increases the bulk on the truck bed, making transportation and loading by truck inefficient and increasing transportation costs.

[0009] Furthermore, when assembling scaffolding on-site, after installing the treads between adjacent horizontal members, baseboards must be attached to both ends of the treads in the width direction. This increases the labor time required to assemble and dismantle the scaffolding on-site, resulting in reduced efficiency in scaffolding assembly and dismantling.

[0010] Furthermore, while the scaffolding described in Patent Document 2 can increase the rigidity of the scaffolding boards and ensure the safety of workers during work, if toe boards are used, the toe boards must be attached to both ends of the scaffolding boards after they have been erected between the horizontal members. As a result, similar to the invention described in Patent Document 1, the efficiency of transportation and removal by truck becomes poor, and transportation costs increase. In addition, the number of man-hours required to assemble the scaffolding on site and to remove it from the site increases, thus reducing the efficiency of scaffolding assembly and removal.

[0011] This invention has been made in view of the above-mentioned conventional problems, and aims to provide a scaffolding board structure that can improve the efficiency of transporting scaffolding to and from the site, as well as the work efficiency when assembling it on site and when removing it from the site. [Means for solving the problem]

[0012] To solve the above-mentioned problems, this invention employs the following means. In other words, the first invention is a scaffolding plank structure for scaffolding used in construction work such as new construction, renovation, and demolition of buildings, characterized in that the scaffolding comprises a group of support columns formed by providing a pair of support columns at predetermined intervals in the beam direction of the building, and providing multiple sets of such pairs of support columns at predetermined intervals in the girder direction of the building, brackets erected between each pair of support columns of the support column group so as to face the beam direction, handrails erected between adjacent support columns of the support column group so as to face the girder direction, scaffolding planks erected between adjacent brackets in the girder direction, and toeboards provided at both ends of each scaffolding plank in the width direction so as to follow the length direction of each scaffolding plank, wherein the scaffolding planks and the toeboards are integrated.

[0013] According to the scaffolding plank structure of this invention, since the scaffolding planks and baseboards are integrated, when installing scaffolding on site, the scaffolding planks can be installed between the brackets, allowing the scaffolding planks and baseboards to be attached as a single unit between the brackets. Similarly, when removing scaffolding, the scaffolding planks can be removed from between the brackets, allowing the scaffolding planks and baseboards to be removed as a single unit. Furthermore, when transporting scaffolding components to or from a site, the scaffolding planks and baseboards can be loaded onto a truck bed as a single component, preventing them from taking up too much space on the truck bed. In addition, by integrating the scaffolding planks and splints, there is no risk of splints being left out during installation.

[0014] Furthermore, the second invention is a scaffolding board structure for scaffolding as described in claim 1, wherein the scaffolding board comprises a reinforcing frame formed by framing rectangular board-shaped members on all four sides, a rectangular board-shaped scaffolding board body integrally provided inside the reinforcing frame, and a pair of hooks integrally provided at both ends of the reinforcing frame in the longitudinal direction and attached to the bracket, and the baseboard is integrally provided at both ends of the scaffolding board body in the width direction, or at the portion of the reinforcing frame along both ends of the scaffolding board body in the width direction.

[0015] According to the scaffolding plank structure of the present invention, since toe boards are integrally provided at both ends in the width direction of the scaffolding plank body, or at the portion of the reinforcing frame that runs along both ends in the width direction of the scaffolding plank body, the toe boards can be positioned along both ends in the width direction of the scaffolding plank by installing the scaffolding plank between the brackets.

[0016] Furthermore, the third invention is a scaffolding board structure for scaffolding as described in claim 2, wherein the scaffolding board body is formed by bending both ends in the width direction and both ends in the length direction of a rectangular board material toward the back surface, thereby forming a beam-intersection side edge of a predetermined width at both ends in the width direction and a girder-line side edge at both ends in the length direction, wherein the beam-intersection side edge and the girder-line side edge are integrally connected to the reinforcing frame side, and the baseboard is integrally provided on the portion of the beam-intersection side edge at both ends in the width direction of the scaffolding board body along the beam-intersection side edge.

[0017] According to the scaffold board structure of the scaffold of the present invention, since the width timbers are integrally provided at the portions along the beam-side edges at both ends in the width direction of the scaffold board body, by installing the scaffold board between the side rails, the width timbers can be arranged at the portions along both ends in the width direction of the scaffold board.

[0018] Moreover, a fourth invention is the scaffold board structure of the scaffold according to claim 3, wherein the scaffold board body is made of a mesh-shaped plate material.

[0019] According to the scaffold board structure of the scaffold of the present invention, width timbers are integrally provided at both ends in the width direction of the scaffold board body made of a mesh-shaped plate material.

[0020] Moreover, a fifth invention is the scaffold board structure of the scaffold according to any one of claims 2 to 4, wherein the width timber is formed from an L-shaped plate material, the base end portion is integrally connected to the upper portion of the scaffold board body by means such as welding or screwing, and the standing portion protrudes upward from the upper surface of the scaffold board body.

[0021] According to the scaffold board structure of the scaffold of the present invention, by connecting the base end portions of the width timbers made of L-shaped plate materials to both ends in the width direction of the scaffold board body by means such as welding or screwing, the width timbers can be arranged at both ends in the width direction of the scaffold board.

[0022] Moreover, a sixth invention is the scaffold board structure of the scaffold according to any one of claims 2 to 4, wherein the width timber is formed from an I-shaped plate material, and the base end portion is integrally connected to the upper portion of the reinforcing frame or the upper portion of the scaffold board body by means such as welding or screwing.

[0023] According to the scaffold board structure of the scaffold of the present invention, by connecting the base end portions of the width timbers made of I-shaped plate materials to the upper portion of the reinforcing frame or the upper portion of the scaffold board, the width timbers can be arranged at both ends in the width direction of the scaffold board.

Effects of the Invention

[0024] As described above, according to the scaffold board structure of the scaffold of the present invention, since the scaffold board and the side timber are integrally formed, by installing the scaffold board between the brackets adjacent in the bay direction, the side timbers can be arranged at both ends in the width direction of the scaffold board. Therefore, the number of man-hours required for installing the scaffold at the site can be reduced, and the number of man-hours required for removing the scaffold from the site can also be reduced, and the time and labor required for installing the scaffold at the site or removing the scaffold from the site can be reduced.

[0025] In addition, the number of components of the scaffold can be reduced. When loading the components of the scaffold from a material storage area or the like onto the truck bed and transporting them to the site or unloading them from the site, the scaffold board and the side timber can be packaged together and loaded onto the truck bed, so that it is possible to prevent bulkiness on the truck bed. As a result, the number of trucks required for transporting the scaffold components to and from the site can be reduced, and the costs required for transportation can be significantly reduced.

[Modes for carrying out the invention]

[0027] The scaffolding plank structure of this invention is applicable to various types of scaffolding used in construction, renovation, and demolition work on buildings such as houses and office buildings, in order to ensure the safety of workers working at heights and to prevent accidents caused by falling materials, tools, etc. In this embodiment, it is applied to wedge-type scaffolding (hereinafter referred to as "scaffolding") used in construction work on low-rise to medium-rise buildings.

[0028] The scaffolding board structure 2 of the scaffolding 1 in this embodiment, as shown in Figures 1 to 3, comprises a scaffolding 1 composed of members such as a jack 10, a base 3, support columns 6, brackets 15, handrails 17, scaffolding boards 20, toe boards 30, and braces 35, and the scaffolding boards 20 and toe boards 30 of this scaffolding 1 are integrated into one structure.

[0029] As shown in Figures 1 to 3 and Figure 15, the jack 10 consists of a metal rectangular plate-shaped base plate 11, a metal rod-shaped screw shaft 12 integrally erected in the center of the base plate 11, a metal annular movable screw 13 that is screwed onto the screw shaft 12 so as to be movable in the axial direction, and a handle 14 integrally provided on the movable screw 13.

[0030] As shown in Figures 1 to 3 and Figures 7 to 8, the base 3 is gate-shaped and consists of a pair of vertical pipes 4, 4 made of single-pipe (carbon steel pipe with zinc plating on the surface) provided at a predetermined interval, and a horizontal pipe 5 made of the same single-pipe material as the vertical pipes 4 that connects the upper ends of both vertical pipes 4, 4. The two vertical pipes 4, 4 and the horizontal pipe 5 are integrally connected by means of welding, screwing, etc.

[0031] A slot 4a is integrally provided on the longitudinal side of the vertical pipe 4 of the base 3, and by fitting the wedge 18 of the handrail 17 (described later) into this slot 4a, the handrail 17 is erected between the vertical pipes 4, 4 of adjacent bases 3, 3 in the longitudinal direction of the building. Note that the base is not limited to a gate shape, but may also be formed in an H shape as shown in Figures 9 and 10. Depending on the required strength of the scaffolding 1 at the site, a gate-shaped or H-shaped base 3 may be selected and used.

[0032] As shown in Figures 1 to 3 and Figure 15, a jack 10 is interposed between each vertical pipe 4 of the base 3 and the ground, and the upper end of the screw shaft 12 of the jack 10 is inserted into the lower end of each vertical pipe 4. By moving the movable screw 13 along the screw shaft 12 via the handle 14 of the jack 10 in the vertical direction, the vertical position of the base 3 and the vertical position of the support column 6 supported by the base 3 can be adjusted.

[0033] As shown in Figures 1 to 3, multiple foundations 3 are installed around the building at predetermined intervals in the longitudinal direction. Each foundation 3 is provided with a pair of vertical pipes 4, 4 positioned at the front and rear in the beam direction of the building, and each vertical pipe 4 of each foundation 3 is supported by jacks 10 in the ground. Note that the beam direction refers to the direction of the building, and the girder direction refers to the direction along the building.

[0034] As shown in Figure 11, the support column 6 is formed from a single pipe of the same material as the vertical pipe 4 and horizontal pipe 5 of the base 3, and multiple fastening parts 7 are provided at predetermined intervals along its longitudinal direction. Each fastening part 7 has a slot 8 provided at four locations around the support column 6 (two in the left-right direction and two in the depth direction in Figure 11). The slots 8 in the left-right direction function as slots 8 into which the wedges 16 of the bracket 15 are fitted, and the slots 8 in the depth direction function as slots 8 into which the wedges 18 of the handrail 17 are fitted.

[0035] As shown in Figure 2, the lower end of the first support column 6 is inserted into the upper end of each vertical pipe 4 of each base 3, and the lower end of the second support column 6 is inserted into the upper end of each first support column 6. By repeating this process, a group of support columns 9 consisting of multiple support columns 6 of a predetermined height can be constructed around the building, as shown in Figures 2 and 3.

[0036] As shown in Figure 12, the bracket 15 is formed from a single pipe of the same material as the support column 6, and tapered wedges 16, 16 are integrally provided at both ends. The bracket 15 is installed integrally between the pair of support columns 6, 6 in the beam direction by inserting the wedges 16, 16 at both ends into the gaps 8, 8 of the pair of support columns 6, 6 which are supported by the respective bases 3, hammering the heads of the wedges 16, 16 into the gaps 8, 8, and locking the lock pins (not shown) on the wedge 16, 16 side to the gaps 8, 8.

[0037] As shown in Figure 13, the handrail 17 is formed from a single pipe of the same material as the support column 6, and tapered wedges 18, 18 are integrally provided at both ends. The handrail 17 is installed integrally between the support columns 6, 6 of the adjacent support columns 6, 6, which are supported by adjacent bases 3, 3 in the longitudinal direction, by inserting the wedges 18, 18 at both ends into the grooves 8, 8 in the longitudinal direction of the adjacent support columns 6, 6, respectively, by hammering the heads of the wedges 18, 18 into the grooves 8, 8, and locking the lock pins (not shown) on the wedge side of the wedges 18, 18 into the grooves 8, 8, thereby installing the handrail 17 integrally between the support columns 6, 6 of the adjacent bases 3, 3 in the longitudinal direction.

[0038] As shown in Figures 4 to 6, the scaffolding board 20 comprises a rectangular board-shaped scaffolding board body 21, a square frame-shaped reinforcing frame 25 integrally provided around the scaffolding board body 21, a pair of roughly C-shaped plate-shaped hooks 28, 28 integrally provided at intervals in the width direction of the scaffolding board body 21 at both ends in the longitudinal direction of the reinforcing frame 25, and plate-shaped reinforcing bars 22 provided at multiple locations on the lower surface side of the scaffolding board body 21, and a baseboard 30 integrally provided at both ends in the width direction of the scaffolding board body 21 so as to extend along the entire length of the scaffolding board body 21.

[0039] The scaffolding board body 21, reinforcing frame 25, hooks 28, reinforcing crossbars 22, and baseboard 30 are made of steel or aluminum, and the scaffolding board body 21 and the reinforcing frame 25 are integrally connected by means of welding, screwing, etc., the reinforcing frame 25 and the hooks 28 are integrally connected by means of welding, screwing, etc., and the scaffolding board body 21 and the reinforcing crossbars 22 are integrally connected by means of welding, screwing, etc.

[0040] The scaffolding board body 21 is formed by bending both ends in the length direction and both ends in the width direction of a rectangular board material at right angles toward the back side, thereby creating a beam-side edge 23 and a girder-side edge 24 perpendicular to the front and back surfaces of the board material, and is integrally connected to the reinforcing frame 25 via these edges 23 and 24.

[0041] The reinforcing frame 25 is formed by framing a pair of rectangular plate-shaped beam-side reinforcing plates 26 that are provided at both ends in the longitudinal direction of the scaffolding board body 21 so as to extend across the entire width of the scaffolding board body 21, and a pair of girder-side reinforcing plates 27 that are provided at both ends in the width direction of the scaffolding board body 21 so as to extend across the entire length of the scaffolding board body 21, and then integrally connecting adjacent beam-side reinforcing plates 26 and girder-side reinforcing plates 27 by means of welding, screwing, etc., to form a rectangular frame shape.

[0042] The scaffolding board body 21 is placed inside the reinforcing frame 25, and the reinforcing plate 26 on the beam side of the reinforcing frame 25 and the beam side edge 23 of the scaffolding board body 21, and the reinforcing plate 27 on the girder side of the reinforcing frame 25 and the girder side edge 24 of the scaffolding board body 21 are connected by means of welding, screwing, etc., thereby integrating the reinforcing frame 25 and the scaffolding board body 21.

[0043] The scaffolding board body 21 is not limited to the plate-like structure described above, but may also be constructed from a mesh plate such as expanded metal. When using a mesh plate, the mesh plate can be integrally connected to the inner surface of the reinforcing frame 25 by welding, screwing, or other means.

[0044] The baseboard 30 is formed from an L-shaped plate made of steel or aluminum, and as shown in Figures 4 to 6, it is integrally provided at both ends in the width direction of the scaffolding board 20 so as to extend along the entire length direction, with the upright portion 31 protruding upward from the upper surface of the scaffolding board 20 by a predetermined length (a length specified in the Industrial Safety and Health Regulations).

[0045] In this case, the baseboard 30 is integrally provided at both ends in the width direction of the scaffolding board 20 by welding, screwing, or other means to multiple points on the base end 32 to the upper surface side of the scaffolding board body 21, thereby configuring the upright portion 31 of the baseboard 30 to protrude upward by a predetermined length from the upper surface of the scaffolding board body 21.

[0046] Furthermore, the baseboard 30 is not limited to an L-shaped plate; an I-shaped plate may also be used. In that case, the baseboard 30 should be integrally connected to the upper part of the girder-side reinforcing plate 27 of the reinforcing frame 25 of the scaffolding board 20 by means of welding, screwing, or other means.

[0047] As shown in Figure 14, the brace 35 has wedges 36, 36 integrally attached to both ends of a steel pipe, and as shown in Figure 3, it is installed diagonally between adjacent support columns 6, 6 in the longitudinal direction. The wedge 36 at one end of the brace 35 is fitted into the slot 8 of one adjacent support column 6 in the longitudinal direction, and the wedge 36 at the other end is fitted into the slot 8 of the other adjacent support column 6, thereby being installed diagonally between adjacent support columns 6, 6 in the longitudinal direction.

[0048] The scaffolding 1, which consists of multiple components as described above, is prepared for installation by packaging each component at a materials storage area, loading them onto a truck, transporting them to the site by truck, and then using a crane or similar equipment to unload each component from the truck.

[0049] Then, at the construction site, as shown in Figure 1, workers place multiple foundations 3 at predetermined intervals in the longitudinal direction of the building, and place jacks 10 at the parts corresponding to each vertical pipe 4 of each foundation 3. At this time, if necessary, base plates 40 are laid between the jacks 10 and the ground to adjust for unevenness in the ground.

[0050] Next, the upper end of the screw shaft 12 of each jack 10 is inserted into the lower end of each vertical pipe 4 of each base 3, and each base 3 is supported on the ground by a pair of jacks 10, 10 (see Figure 15). At this time, the orientation of each base 3 is adjusted so that the pair of vertical pipes 4, 4 of each base 3 are positioned front to back in the direction of the building's beams.

[0051] Next, a handrail 17 is placed between the vertical pipes 4, 4 of adjacent foundations 3 in the longitudinal direction, and the wedges 18, 18 at both ends of the handrail 17 are fitted into the slots 4a of the vertical pipes 4, thereby installing the handrail 17 between the vertical pipes 4, 4 of adjacent foundations 3 in the longitudinal direction.

[0052] Next, as shown in Figure 2, the scaffolding board 20 is placed between adjacent foundations 3, 3 in the longitudinal direction, and the hooks 28, 28 at both ends in the longitudinal direction are attached to adjacent brackets 15, 15 in the longitudinal direction, thereby erecting the scaffolding board 20 between adjacent foundations 3, 3 in the longitudinal direction.

[0053] Next, the lower ends of the support columns 6 are inserted into the upper ends of the vertical pipes 4 of each base 3, and a bracket 15 is placed between the pair of support columns 6, 6 supported by each base 3. The wedges 16, 16 at both ends of the bracket 15 are inserted into the slots 8, 8 of each support column 6, and the heads of the wedges 16, 16 are struck with a hammer or the like to fit them into the slots 8, 8, and the lock pins (not shown) on the wedge 8, 8 side are locked to the slots 8, 8 side. In this way, the bracket 15 is erected between the pair of support columns 6, 6 of each base 3.

[0054] Next, a handrail 17 is placed between the support columns 6, 6 which are supported by adjacent foundations 3, 3 in the longitudinal direction. The wedges 18, 18 at both ends of the handrail 17 are inserted into the slots 8, 8 of each support column 6, 6. The heads of the wedges 18, 18 are struck with a hammer or the like to fit them into the slots 8, 8, and the lock pins (not shown) on the wedge 8, 8 side are locked into the slots 8, 8. In this way, the handrail 17 is installed between the support columns 6, 6 of adjacent foundations 3, 3.

[0055] Next, the scaffolding board 20 is placed between adjacent brackets 15, 15 in the longitudinal direction, and the hooks 28, 28 at both ends of the scaffolding board 20 in the longitudinal direction are attached to the brackets 15, thereby erecting the scaffolding board 20 between adjacent brackets 15, 15 in the longitudinal direction. As a result, the scaffolding board 20 is placed between adjacent brackets 15, 15, and the baseboard 30, which is integrally formed with the scaffolding board 20, is positioned between adjacent support columns 6, 6 in the longitudinal direction, protruding upward from the top surface of the scaffolding board 20 by a predetermined length. This prevents tools and other items from falling from the top of the scaffolding board 20.

[0056] Next, as shown in Figure 3, a diagonal brace 35 is placed between adjacent support columns 6, 6 in the girder direction, and the wedges 36, 36 at both ends of the brace 35 are fitted into the slots 8 of one adjacent support column 6 and the slots 8 of the other support column 6, thereby installing the diagonal brace 35 between adjacent support columns 6, 6 in the girder direction.

[0057] This allows for the construction of the first layer of scaffolding 1. By repeating this process, a multi-layered scaffolding 1 can be constructed around the building. Note that Figure 3 shows only the first layer of scaffolding 1.

[0058] In the scaffolding board structure 2 of this embodiment configured as described above, the scaffolding board 20 and the baseboard 30 are integrally formed. Therefore, when installing the scaffolding 1 on site, the scaffolding board 20 can be installed between the brackets 15, 15, thereby attaching the scaffolding board 20 and the baseboard 30 as a single unit between the brackets 15, 15. Consequently, in addition to the work of attaching the scaffolding board 20 between the brackets 15, 15, the work of attaching the baseboard 30 to the top of the scaffolding board 20 is eliminated, reducing the overall number of work hours, the time and effort required to install the scaffolding 1, and enabling the scaffolding 1 to be installed efficiently on site.

[0059] Furthermore, when removing scaffolding 1 from the site, the scaffolding boards 20 can be removed from the space between the brackets 15, 15, allowing the scaffolding boards 20 and the baseboards 30 to be removed as a single unit. This reduces the time and effort required to remove scaffolding 1, enabling efficient removal of scaffolding 1 from the site.

[0060] Furthermore, since the scaffolding board 20 and the baseboard 30 are integrally formed, the bulk on the truck bed can be reduced when transporting the components of the scaffolding 1 to or from the site. This reduces the number of trucks required for transport, thereby reducing the time and effort required for transport and significantly lowering the costs associated with transport.

[0061] In the above description, we have explained an example in which the scaffolding board structure 2 of the present invention is applied to a wedge-type scaffolding. However, the present invention may also be applied to various other types of scaffolding (such as frame scaffolding), and the same effects and advantages will be achieved in that case as well.

[0062] Furthermore, although the scaffolding board structure 2 of this invention was applied to a scaffolding board 20 having a scaffolding board body 21 made of a rectangular board-shaped member, or a scaffolding board 20 having a scaffolding board body 21 made of a mesh board, this invention may also be applied to various other types of scaffolding boards 20, and the same effects and advantages will be obtained in that case as well.
