Description

Technical Field

[0001] Embodiments of the present invention relate to a detachable support fitting for a falsework gap filling plate and a method of using the same.

Background Art

[0002] Generally, at a construction site, in order to prevent industrial accidents at the scaffold, rules regarding the gaps in the scaffold are defined by the Industrial Safety and Health Regulations. When gaps occur in the scaffold, it is necessary to ensure the safety of parts from falling and workers by closing the gaps.

[0003] For example, in a conventional framed scaffold, a scaffold board with a hook is used, and the scaffold board is installed by hanging the hook of the scaffold board between horizontal members (horizontal pipes) of a pair of portal-shaped building frames standing opposite each other.

[0004] At this time, the scaffold board is installed one piece or a plurality of pieces are installed in parallel according to the width between the legs of the building frame (corresponding to the length of the horizontal member).

[0005] The width between the legs of the building frame (the length of the horizontal member) and the width of the scaffold board have a margin in their dimensions in consideration of the ease of assembly and disassembly of the scaffold at the site. Therefore, when a plurality of scaffold boards are installed in parallel, a greater or lesser gap occurs between two adjacent scaffold boards.

[0006] In the case of a single-pipe scaffold, a pair of portal-shaped single pipes are formed by two building sites that serve as legs in the building frame and braces that serve as horizontal members in the building frame horizontally combined between the two building sites. The scaffold board can be installed in the same way as in the case of a framed scaffold by hanging the hook of the scaffold board between the braces of the pair of portal-shaped single pipes standing opposite each other.

[0007] Conventionally, several techniques have been considered for closing the gaps that occur around the scaffold board installed on the scaffold.

[0008] For example, there are scaffolding board gap plates with hooks that are attached to the rectangular gap between the side ends of two scaffolding boards with hooks that are installed in parallel, by hooking the hooks onto a horizontal member (horizontal pipe) (see, for example, Patent Documents 1 to 3), and scaffolding board gap plates equipped with means for engaging with the side ends of the scaffolding boards that are attached by engaging with the side ends of the scaffolding boards (see, for example, Patent Document 4). In addition, there are gap-closing members that protrude from both ends of the scaffolding board, between the hooks at each end, to close the gap between both ends of the scaffolding board and the horizontal member (horizontal pipe) (see, for example, Patent Document 5). [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] Japanese Patent Application Publication No. 11-270128 [Patent Document 2] Japanese Patent Publication No. 2012-097534 [Patent Document 3] Japanese Patent Publication No. 2017-031635 [Patent Document 4] Japanese Patent Application Publication No. 11-264239 [Patent Document 5] Japanese Patent Publication No. 2022-030008 [Overview of the Initiative] [Problems that the invention aims to solve]

[0010] The construction methods for scaffolding vary depending on the site requirements. For example, in the case of frame scaffolding, a set of scaffolding consisting of a pair of opposing frames and scaffolding boards with hooks installed between the horizontal members of the pair of frames can be arranged in parallel and adjacent to each other to construct a wider scaffolding in the width direction of the scaffolding boards.

[0011] In this case, between the two sets of scaffolding placed adjacent to each other, there will be a gap of at least two support posts (or two uprights in the case of single-pipe scaffolding) between the side ends of the scaffolding planks of one set and the other set.

[0012] However, since there are no horizontal members (braces in the case of single-pipe scaffolding) between the columns of two adjacent sets of scaffolding that create such gaps (between the uprights in the case of single-pipe scaffolding), the conventional techniques for filling gaps around scaffolding boards mentioned above cannot adequately fill the gaps between two adjacent sets of scaffolding.

[0013] The problem that this invention aims to solve is to provide a detachable support fitting for a scaffolding gap-filling plate and a method for using the same, which can appropriately fill the gap that occurs between two sets of scaffolding placed adjacent to each other. [Means for solving the problem]

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments of the detachable support bracket for scaffolding gap-filling plates and the method of using the present invention will be described with reference to the drawings.

[0018] (Configuration and operation of the embodiment) Figure 1 is an external perspective view showing an example of scaffolding 1 constructed using the detachable support fitting 10 for scaffolding gap-filling plates according to the embodiment.

[0019] Figure 1 shows a scaffolding 1 constructed by placing two sets of scaffolding adjacent to each other in parallel, each set consisting of a pair of gate-shaped scaffolding frames 2,2 erected opposite each other, and two scaffolding boards 3,3 with hooks installed in parallel between the horizontal members 2b,2b (horizontal members) of the pair of scaffolding frames 2,2.

[0020] In this example, both sets of scaffolding are shown with the frame 2 connected in two tiers, and the hooks 3a at both ends of the scaffolding board 3 attached between the horizontal members 2b, 2b of the opposing lower frame 2, 2.

[0021] Note that illustrations of the reinforcing steel members provided in the frame 2, the cross braces combined with the frame 2, and the connecting pins that connect the leg columns 2a of the frame 2 are omitted.

[0022] In Figure 1, we assume that the direction corresponding to the depth shown is the width direction or left-right direction of the scaffolding, and the direction corresponding to the left-right direction shown is the length direction or front-back direction of the scaffolding.

[0023] As shown in Figure 1, in the scaffolding 1 of this embodiment, two detachable support brackets 10 for scaffolding gap-filling plates are used in pairs to horizontally surround the space between the vertical upper ends of one leg column 2a (support column) and the other leg column 2a (support column) of two adjacent scaffolding sets that are placed parallel to each other in the width direction. By attaching a rectangular scaffolding gap-filling plate 20 of a size (size) corresponding to the width and length of the gap between the side ends of one scaffolding board 3 and the other scaffolding board 3 of two adjacent scaffolding sets in the width direction, the gap can be filled.

[0024] The scaffolding gap filler plate 20 can be used by removing the hooks from a general-purpose scaffolding gap filler plate, or multiple sizes of scaffolding gap filler plates can be prepared in advance and used.

[0025] Figure 2 is a partially transparent external perspective view showing the configuration of the detachable support bracket 10 for the scaffolding gap-filling plate.

[0026] The detachable support fitting 10 for the scaffolding gap-filling plate is made of the same steel material as various components for constructing scaffolding (frame 2, scaffolding board 3, single pipe, etc.), and has a rectangular, annular fitting body 11 with vertically communicating space to horizontally enclose two vertically adjacent leg columns 2a, 2a (support columns) between two adjacent sets of scaffolding.

[0027] The metal fitting body 11 has long sides 11a and 11b that are parallel to each other along the direction in which the two leg columns 2a, 2a are adjacent, that is, along the width direction of the two sets of scaffolding that are adjacent in parallel, and short sides 11c and 11d that are parallel to each other and connect the long sides 11a and 11b at one end (left side) and the other end (right side), respectively.

[0028] The corner of the metal fitting body 11, where the long side portion 11a on one side (rear) connects to the short side portion 11d on the other end (right side), is rotatably connected via a hinge 12. Furthermore, as shown by arrow A, the opening and closing operation of the long side portion 11a is locked or unlocked by engaging or disengaging a lock lever 13a (rotating lock mechanism), which is rotatably mounted along the front surface of the short side portion 11c with the tip of the long side portion 11a as a pivot point, with a lever engaging portion 13b (rotating lock mechanism), which is erected on the front surface of the short side portion 11c.

[0029] Furthermore, the tip of the long side portion 11a of the metal fitting body 11, which opens and closes, and the tip of the short side portion 11c, which abuts against it when locked in the open and closed position to form a corner, are formed so that the upper part of the long side portion 11a has a convex portion 11a1 and the lower part has a concave portion 11a2, while the upper part of the short side portion 11c has a concave portion 11c1 and the lower part has a convex portion 11c2, and they are arranged in an alternating manner, so that the load applied to the tip of the long side portion 11a is applied to the short side portion 11c.

[0030] Furthermore, the load applied to the other end (the pivot point) of the long side 11a is applied to the short side 11d via the hinge 12.

[0031] Similarly, the load applied to the other (front) long side portion 11b of the metal fitting body portion 11 is distributed and applied to the short side portion 11c on one end (left side) and the short side portion 11d on the other end (right side).

[0032] At the lower end of the short side portion 11c on one end (left side) of the metal fitting body portion 11 and at the lower end of the short side portion 11d on the other end (right side) of the metal fitting body portion 11, two symmetrical main support arms 14, 14 of a fixed length are provided integrally with the short side portions 11c, 11d, respectively, along the horizontal member 2b (horizontal member) that extends horizontally to the left from one of the leg columns 2a enclosed by the metal fitting body portion 11 and the horizontal member 2b (horizontal member) that extends horizontally to the right from the other leg column 2a enclosed by the metal fitting body portion 11.

[0033] At the tip of each main support arm 14, 14, there is an arc-shaped hook portion 14a, 14a that grips the horizontal members 2b, 2b located along the bottom of each support arm 14, 14 from above, without any displacement, and transmits the load applied to the main body of the fitting 11.

[0034] At the lower end of one (rear) long side portion 11a and the lower end of the other (front) long side portion 11b of the metal fitting body 11, L-shaped plate support portions 15a and L-shaped plate support portions 15b are provided symmetrically front to back. These extend horizontally from a position vertically lowered at a height corresponding to, for example, the diameter of the horizontal member 2b, to the rear and to the front, respectively, with a length equal to the combined width of the two leg columns 2a, 2a enclosed by the metal fitting body 11. L-shaped plate support portions 15a support the front (one end) of the scaffolding gap filling plate 20 positioned behind the metal fitting body 11, and L-shaped plate support portions 15b support the rear (other end) of the scaffolding gap filling plate 20 positioned in front of the metal fitting body 11.

[0035] On the upper surface of the plate support portion 15a on one side (rear) of the metal fitting body portion 11, a pair of plate fixing portions 16a, 16a facing each other in the width direction are provided to engage and fix both ends of the front portion (one end side) of the scaffolding gap filling plate 20 from both sides.

[0036] Both plate fixing parts 16a, 16a are slidably mounted on the upper surface of the plate support part 15a via a lockable slide rail 17a that has a widthwise sliding function, as shown by arrow B, and can be switched between a slidable state and a non-slidable state (locked state) according to the switching operation of the lock lever 17a1.

[0037] Similarly, on the upper surface of the other (front) plate support portion 15b of the metal fitting body portion 11, a pair of plate fixing portions 16b, 16b facing each other in the width direction are provided to engage and fix both ends of the rear (other end) of the scaffolding gap filling plate 20 from both sides.

[0038] Similarly, the plate fixing parts 16b, 16b are slidably mounted on the upper surface of the plate support part 15b via a lockable slide rail 17b that has a widthwise sliding function, as shown by arrow B, and can be switched between a slidable state and a non-slidable state (locked state) according to the switching operation of the lock lever 17b1.

[0039] (Instructions for using the detachable support bracket 10) Here, as shown in Figure 1, we will explain the procedure for filling the gap between two sets of scaffolding that are arranged parallel to each other in the width direction of the scaffolding 1, by using two sets of detachable support brackets 10 for scaffolding gap-filling plates as a pair.

[0040] Figure 3 is an external perspective view illustrating the first step in the procedure for using the detachable support bracket 10.

[0041] Using the detachable support bracket 10, rotate the lock lever 13a (rotation lock mechanism) of the bracket body 11 to release the lock from the lever engagement portion 13b (rotation lock mechanism), and rotate one of the long sides 11a to open the bracket body 11, as shown by arrow C.

[0042] Figure 4 is an external perspective view illustrating the procedure for using the detachable support bracket 10 (part 2).

[0043] Figure 5 is an external perspective view illustrating the procedure (part 3) for using the detachable support bracket 10.

[0044] With the metal fitting body 11 open, the metal fitting body 11 is attached to the scaffolding 1 so as to horizontally surround the space between the upper ends of one leg column 2a (support column) and the other leg column 2a (support column) between two sets of scaffolding that are placed adjacent to each other in parallel.

[0045] Then, the lock lever 13a is engaged with the lever engagement portion 13b, locking the metal fitting body portion 11 in the closed position.

[0046] In this case, the detachable support bracket 10, due to its own weight, lowers to a position where the symmetrical main support arms 14, 14 and the hook portions 14a, 14a provided at their tips rest on the horizontal members 2b, 2b of the left and right scaffolding frames 2, 2, which are located below the detachable support bracket 10. This allows the load applied to the main body of the bracket 11 to be transmitted to the left and right horizontal members 2b, 2b. At the same time, the main body of the bracket 11 connects two sets of scaffolding that are adjacent to each other in parallel, and positions the plate support portions 15a, 15b, which are provided symmetrically in the front and back of the main body of the bracket 11, between the side ends of the scaffolding boards 3, 3 attached to each of the two sets of scaffolding.

[0047] Furthermore, even if the detachable support bracket 10 does not have the main support arms 14, 14 and the hook portions 14a, 14a at their tips, the left and right short sides 11c, 11d of the bracket body 11 will descend to a position where they rest directly on the horizontal members 2b, 2b of the left and right frame 2, 2 located below them, thereby transmitting the load applied to the bracket body 11 to the left and right horizontal members 2b, 2b.

[0048] Figure 6 is an external perspective view illustrating the procedure (part 4) for using the detachable support bracket 10.

[0049] As shown in Figures 3 to 5, the first detachable support bracket 10 is attached to the adjacent leg columns 2a, 2a of the adjacent scaffolding frames 2, 2 of two parallel sets of scaffolding. The second detachable support bracket 10 to be combined with it is attached in the same manner as described above, in front of or behind (in this case, behind) the first detachable support bracket 10, between the tips of the adjacent leg columns 2a, 2a (support columns) of the adjacent scaffolding frames 2, 2, as shown in Figure 6.

[0050] Here, in two sets of scaffolding adjacent to each other in the width direction, two detachable support brackets 10 are similarly attached between the upper ends of adjacent leg columns 2a, 2a (support columns) on the front side and between the upper ends of adjacent leg columns 2a, 2a (support columns) on the rear side, with the rear L-shaped plate support portion 15a of the front detachable support bracket 10 and the front L-shaped plate support portion 15b of the rear detachable support bracket 10 facing each other.

[0051] Figure 7 is an external perspective view illustrating the procedure (5) for using the detachable support bracket 10.

[0052] In the detachable support bracket 10 attached to the front side and the detachable support bracket 10 attached to the rear side between the two sets of scaffolding on the left and right, the pair of plate fixing parts 16a and 16b of the opposing plate support parts 15a and 15b are slid in the width direction as shown by arrow B to widen the gap between them.

[0053] Figure 8 is an external perspective view illustrating the procedure (6) for using the detachable support bracket 10.

[0054] A rectangular scaffolding gap-filling plate 20 is prepared, sized to match the width and length of the gap between the side ends of one scaffolding board 3 and the other scaffolding board 3 between two sets of scaffolding. The front (one end) and rear (the other end) of the scaffolding gap-filling plate 20 are then placed on the board support portion 15a of the opposing front detachable support bracket 10 and the board support portion 15b of the rear detachable support bracket 10.

[0055] Then, as shown by arrow X in Figure 8, the pair of plate fixing parts 16a of the front detachable support bracket 10 and the pair of plate fixing parts 16b of the rear detachable support bracket 10 are slid to narrow the distance between them, so that both ends of the front of the scaffolding gap filling plate 20 are clamped and fixed by the plate fixing parts 16a of the front detachable support bracket 10, and both ends of the rear of the scaffolding gap filling plate 20 are clamped and fixed by the plate fixing parts 16b of the rear detachable support bracket 10.

[0056] This allows the rectangular gap that occurs between the side ends of one scaffolding board 3 and the other scaffolding board 3 between two sets of scaffolding that are adjacent to each other in the scaffolding 1 to be filled with a scaffolding gap filler board 20 that corresponds to the width and length of the gap.

[0057] In this case, by using a scaffolding gap filler plate 20 such that the gap d remaining between both ends of the scaffolding gap filler plate 20 and the adjacent scaffolding boards 3, 3 is, for example, 3 cm or less, a predetermined gap d can be made, thereby constructing a scaffolding 1 that satisfies the provisions of the Industrial Safety and Health Act.

[0058] It goes without saying that, in the same way as described above, the gap between two sets of scaffolding adjacent to each other can be similarly filled at any point on scaffolding 1 by attaching the detachable support brackets 10 to the two sets of scaffolding constructed continuously on the front side and the two sets of scaffolding constructed continuously on the rear side of the two sets of scaffolding adjacent to each other as shown in the diagram, and by installing the scaffolding gap-filling plates 20.

[0059] (Summary of the embodiments) According to the detachable support fitting 10 for scaffolding gap-filling plates of this embodiment, the fitting comprises a rectangular, annular fitting body 11 that is detachably attached so as to horizontally surround the upper ends of adjacent leg columns 2a, 2a (support columns) of two sets of scaffolding adjacent to each other in parallel, one plate support portion 15a provided on one long side 11a and the other long side 11b of the fitting body 11 that are parallel to each other in the width direction where the leg columns 2a, 2a are adjacent, and which support one end of the scaffolding gap-filling plate 20 that is placed on one side of the fitting body 11, the other plate support portion 15b provided on the other side of the fitting body 11 to support the other end of the scaffolding gap-filling plate 20 that is placed on the other side of the fitting body 11, and a pair of plate fixing portions 16a, 16b provided on the plate support portions 15a, 15b respectively, which clamp and fix the scaffolding gap-filling plate 20 supported by the plate support portions 15a, 15b from the width direction.

[0060] Then, the two detachable support brackets 10, 10 are attached to the upper ends of the adjacent leg columns 2a, 2a (support columns) on the front side and the adjacent leg columns 2a, 2a (support columns) on the rear side of the two adjacent sets of scaffolding, respectively. The opposing plate support parts 15a (plate fixing part 16a) and plate support parts 15b (plate fixing part 16b) of the front detachable support bracket 10 and the rear detachable support bracket 10 are used to install and fix a scaffolding gap filler plate 20 that corresponds to the width and length of the rectangular gap between the two adjacent sets of scaffolding.

[0061] Therefore, the detachable support bracket 10 for the scaffolding gap-filling plate of this embodiment makes it possible to properly fill the gap between two sets of scaffolding placed adjacent to each other.

[0062] In the embodiments described above, the case where the target scaffolding 1 is mainly frame scaffolding was explained, but it is not limited to this. Even with single-pipe scaffolding or other types of scaffolding, if a pair of gate-shaped frames, each constructed in a gate shape with two cylindrical steel columns and one horizontal member, are placed facing each other, and one or more scaffolding boards 3 with hooks are hung and attached between the horizontal members of the opposing gate-shaped frames, and at least two sets of scaffolding are constructed in parallel adjacent to each other in the width direction of the scaffolding boards 3, then the same effect can be obtained by using the detachable support fitting 10 for the scaffolding gap-filling plate of the embodiment in the same way.

[0063] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of Symbols]
