Description

[Technical Field]

[0001] The present invention relates to a scaffolding bracket for supporting scaffolding used at construction sites. [Background technology]

[0002] When setting up scaffolding, horizontally protruding scaffolding brackets are attached to iron pipes that are erected approximately vertically, and scaffolding boards are placed on top of the multiple scaffolding brackets. However, there are times when the scaffolding is temporarily unnecessary due to the construction process, and in such cases, it is time-consuming to remove the scaffolding brackets and then reinstall them when they are needed again.

[0003] Patent Document 1 describes a method for flipping up unnecessary scaffolding brackets so that they do not get in the way. [Prior art documents] [Patent documents]

[0004] Patent Document 1: Japanese Patent Application Laid-Open No. 2000-17834 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the scaffolding bracket described in Patent Document 1 requires a mechanism to prevent the bracket from falling downward under its own weight when it is lifted upward, which increases costs and complicates the assembly of the scaffolding bracket.

[0006] The present invention aims to solve the above problems and realize a low-cost, simple, foldable scaffolding telescopic bracket. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a foldable scaffolding telescopic bracket, a scaffolding support bracket for supporting a scaffolding board; A vertical support member whose one end is provided in a direction substantially perpendicular to the scaffolding support fitting at a first position near one end of the scaffolding support fitting and is rotatable; and an inclined support member, one end of which is inclined relative to the scaffolding support fitting and is rotatable, at a second position near the other end of the scaffolding support fitting, The inclined support member is composed of a first inclined portion having one end rotatably attached to the second position of the scaffolding support fitting, and a second inclined portion attached to the other end of the vertical support member, and The inclined support member A foldable scaffolding telescopic bracket is provided, characterized in that the other end of the first inclined portion and one end of the second inclined portion are screwed together in a separable manner at the middle portion.

[0008] With this configuration, the first inclined section and the second inclined section can be separated, and the scaffolding support bracket can be folded downward using one end of the vertical support member as a fulcrum, eliminating the need for a mechanism to prevent it from falling downward under its own weight when flipped upward, making it possible to realize a low-cost, simple foldable scaffolding telescopic bracket.

[0009] A folding scaffolding telescopic bracket, the first position having a first support piece having a substantially plate shape with one end attached to the scaffolding support bracket, The first support piece and the vertical support member are fastened together with a first bolt, and the first bolt is unscrewed to make the scaffolding support fitting rotatable. The second position has a second support piece having a substantially plate shape with one end attached to the scaffolding support fitting, The second support piece and the inclined support member may be fixed by screwing a second bolt together, and the inclined support member may be made rotatable by loosening the second bolt.

[0010] This configuration allows the vertical support members and inclined support members to be easily attached to the scaffolding support fittings.

[0011] A foldable scaffolding telescopic bracket may be configured such that when the first support piece and the vertical support member are screwed together with a first bolt, a first anti-rotation protrusion is provided near the end of the vertical support member so as to be positioned outside the first support piece in the opposite direction to the inclined support member, to prevent the scaffolding support bracket from rotating toward the vertical support member with the first bolt as a fulcrum.

[0012] With this configuration, when the scaffolding is set up using the folding scaffolding telescopic bracket, the scaffolding support bracket can be supported so that it does not fall downward due to the load from the scaffolding.

[0013] A folding scaffolding telescopic bracket, having a third bolt hole at the other end of the first inclined portion of the inclined support member, The configuration may also include a second anti-rotation protrusion located near one end of the second inclined portion so as to be positioned outside the first inclined portion in the opposite direction to the vertical support member when the other end of the first inclined portion and one end of the second inclined portion are screwed together with a third bolt through the third bolt hole, to prevent the first inclined portion from rotating in the opposite direction to the vertical support member with the third bolt as a fulcrum.

[0014] This configuration makes it possible to prevent the first and second inclined portions of the inclined member from unexpectedly separating due to the load from the scaffolding when the scaffolding is set up using the folding scaffolding telescopic bracket.

[0015] A folding scaffolding telescopic bracket may be configured such that the third bolt hole at the other end of the first inclined portion has a center on the opposite side of the vertical support member from a center line that runs vertically through the first inclined portion, and opens on the opposite side of the vertical support member.

[0016] With this configuration, by having a center on the opposite side of the vertical support member from the center line that runs through the first inclined portion, it is possible to further support the load from the scaffolding when the scaffolding is set up using the folding scaffolding extendable bracket. Also, by having the third bolt hole of the first inclined portion open on the opposite side of the vertical support member, it is possible to easily separate the first inclined portion and the second inclined portion.

[0017] In order to solve the above problem, the present invention provides a method for using a folding scaffolding extension bracket that can be folded downward, a scaffolding support bracket for supporting a scaffolding board; At a first position near one end of the scaffolding support fitting, one end is positioned in a direction substantially perpendicular to the scaffolding support fitting. Screw in the first bolt a vertical support member provided and rotatable; and an inclined support member, one end of which is inclined relative to the scaffolding support fitting and is rotatable, at a second position near the other end of the scaffolding support fitting, The inclined support member has one end rotatably positioned at the second position on the scaffolding support fitting. Screw in the second bolt a first inclined portion attached to the other end of the vertical support member, and a second inclined portion attached near one end to the other end of the vertical support member; The inclined support member The other end of the first inclined portion and one end of the second inclined portion are separably connected at a middle portion. With the third bolt a folding scaffolding telescopic bracket that is screwed to the scaffolding; The first bolt, the second bolt, and the third bolt are screwed together to fix the vertical support member, the first inclined portion, and the second inclined portion so that the scaffolding support fitting is in a substantially horizontal direction and the vertical support member is substantially vertical downward from the scaffolding support fitting, and a scaffolding board is placed on the scaffolding support fitting to form a scaffold; When no scaffolding is to be formed, the method of using the foldable scaffolding telescopic bracket is characterized in that the first bolt, the second bolt, and the third bolt are loosened to separate the first inclined portion and the second inclined portion, and the scaffolding support bracket is folded downward.

[0018] With this configuration, a low-cost, simple foldable scaffolding telescopic bracket can be created by loosening the first bolt, second bolt, and third bolt to separate the first inclined portion and the second inclined portion, and folding the scaffolding support bracket downward using the first bolt as a fulcrum. [Effects of the Invention]

[0019] The folding scaffolding telescopic bracket and method of using the folding scaffolding telescopic bracket of the present invention allow a low-cost, simple folding scaffolding telescopic bracket to be realized by separating the first inclined section and the second inclined section and folding the scaffolding support bracket downward using the first bolt as a fulcrum.

[0022] The foldable scaffolding extendable bracket 100 in Example 1 includes a scaffolding support fitting 10 that is substantially cylindrical and made primarily of iron, a vertical support member 20 that is substantially flat, plate-like, and made primarily of iron, and an inclined support member 30 that is substantially flat, plate-like, and made primarily of iron. The ends of the scaffolding support fitting 10 are cut into a substantially arc shape so that it can be attached to an iron pipe P in a substantially horizontal position. The scaffolding support fitting 10 is used to support a scaffolding board, horizontal fall protection net, or fall protection shelf (not shown) that is attached substantially horizontally to the iron pipe P. To attach the foldable scaffolding extendable bracket 100 to an existing iron pipe P, the scaffolding support fitting 10 is aligned perpendicular to the iron pipe P, which is installed substantially vertically (i.e., the scaffolding support fitting 10 is aligned horizontally), and then fastened to the iron pipe P using fasteners B attached to the vertical support member 20. At this time, the other end (on the iron pipe P side) of the inclined support member 30 abuts against the iron pipe P to support the foldable scaffolding extendable bracket 100. For this reason, the other end of the inclined support member 30 is formed in a substantially arc shape.

[0023] Furthermore, the scaffolding support bracket 10 is extendable to fit the size of the scaffolding board. In other words, by loosening the fastener 18, the tip of the scaffolding support bracket 10 can be pulled out to lengthen it, or pushed in to shorten it, as shown by the two-dot chain line in Figure 1. If the fastener 18 is tightly screwed in, the tip of the scaffolding support bracket 10 cannot be pulled out or pushed in, and the same length can be maintained.

[0024] In Example 1, the scaffolding support bracket 10 is substantially cylindrical and made primarily of iron, but this is not necessarily limited to this and can be modified as appropriate. For example, it may be a cylindrical member with a substantially polygonal cross-section, or a linear member with any cross-sectional shape can be used. Furthermore, the vertical support member 20 and the inclined support member 30 are substantially flat, plate-shaped members made primarily of iron, but this is not necessarily limited to this and can be modified as appropriate. For example, members with a cylindrical cross-section may be used. Furthermore, the scaffolding support bracket 10, the vertical support member 20, and the inclined support member 30 are made primarily of iron, but this is not necessarily limited to this and can be modified as appropriate. For example, they may be made of a material other than iron.

[0025] The scaffolding support fitting 10 has a first support piece 11 attached at a first position 16 near one end thereof and a second support piece 12 attached at a second position 17 near the other end thereof. The first support piece 11 and the second support piece 12 are both made of a material primarily made of iron and have approximately flat surfaces, and the approximately flat surfaces are attached by welding facing downward (in the -y direction) parallel to the extension direction of the scaffolding support fitting 10. The first support piece 11 is disposed perpendicular to the scaffolding support fitting 10, while the second support piece 12 is disposed at an angle toward the first support piece 11. Furthermore, through holes for bolt screwing are provided at approximately the centers of the approximately flat surfaces of the first support piece 11 and the second support piece 12.

[0026] In Example 1, the first support piece 11 and the second support piece 12 are attached to the scaffolding support fitting 10 by welding, but this is not necessarily limited to this and can be modified as appropriate. For example, they may be attached by any method such as bolting.

[0027] One end of the vertical support member 20 is screwed into the through-hole of the first support piece 11 with a first bolt 14. This allows the scaffolding support bracket 10 to be attached and fixed in a substantially vertical direction. Furthermore, by loosening the first bolt 14, the scaffolding support bracket 10 can be folded toward the vertical support member 20 (i.e., downward). When constructing scaffolding by placing scaffolding boards on the folding scaffolding extendable bracket 100, the vertical support member 20 is screwed into the first support piece 11. At this time, a first rotation prevention protrusion 131 is provided near the end of the vertical support member 20 to prevent the scaffolding support bracket 10 from falling toward the vertical support member 20 due to the load from the scaffold and rotating toward the vertical support member 20 around the first bolt 14 as a fulcrum.

[0028] The first rotation-preventing protrusion 131 in Example 1 is formed by cutting iron into a substantially rectangular parallelepiped shape and is provided so as to protrude from a flat surface 133 of the substantially plate-shaped first rotation-preventing member 13. An end of the first rotation-preventing member 13 is welded to the back surface side (z-direction side) of the vertical support member 20 so as to extend from the end of the vertical support member 20. This flat surface 133 has a through-hole 132 through which the first bolt 14 passes, allowing it to be screwed to the first support piece 11. Here, when the vertical support member 20 is screwed to the first support piece 11, the first rotation-preventing protrusion 131 is located on the outer side (-x-direction side) of the first support piece 11, in the direction opposite to the inclined support member 30. This prevents the scaffolding support bracket 10 from tipping toward the vertical support member 20 due to the load from the scaffold, and prevents the scaffolding support bracket 10 from rotating around the first bolt 14 in the direction of the vertical support member 20.

[0029] The inclined support member 30 is attached at an angle to the scaffolding support fitting 10 by screwing one end of it to the second support piece 12 with a second bolt 15. More specifically, the inclined support member 30 is composed of a first inclined portion 31 and a second inclined portion 32 connected together, and one end of the first inclined portion 31 is screwed and fixed to the second support piece 12, and the first inclined portion 31 can be made rotatable by loosening the screw. In addition, the second inclined portion 32 is welded to the other end of the vertical support member 20 at its intermediate position.

[0030] In the middle of the inclined support member 30, the first inclined portion 31 and the second inclined portion 32 are separably connected by a third bolt 34 threaded through a third bolt hole provided on the other end of the first inclined portion 31 and one end of the second inclined portion 32. In this case, when the first inclined portion 31 is screwed to the second support piece 12, a second rotation prevention protrusion 331 is provided near one end of the second inclined portion to prevent the first inclined portion 31 from rotating in the opposite direction to the vertical support member 20 with the third bolt 34 as a fulcrum.

[0031] The second rotation-preventing protrusion 331 in the first embodiment is formed by cutting iron into a substantially rectangular parallelepiped shape so as to protrude from the flat surface 333, and is provided at the end of the substantially plate-shaped second rotation-preventing member 33. The end of the second rotation-preventing member 33 is welded to the back surface (z-direction side) of the second inclined portion 32 so as to extend from the end of the second inclined portion 32. The flat surface 333 has a through-hole 332 through which the third bolt 34 passes. When the other end of the first inclined portion 31 and one end of the second inclined portion 32 are screwed together, the second rotation-preventing protrusion 331 is positioned outside the first inclined portion 31 (x-direction) in the opposite direction from the vertical support member 20. This prevents the first inclined portion 31 from tipping in the opposite direction from the vertical support member 20 due to a load from the scaffolding, and prevents the first inclined portion 31 from rotating around the third bolt 34 as a fulcrum in the opposite direction from the vertical support member 20.

[0032] Furthermore, in order to prevent the first inclined portion 31 and the second inclined portion 32 from rotating in the opposite direction to the vertical support member 20 with the third bolt 34 as a fulcrum due to the load from the scaffolding, the third bolt hole has its center at a position that is a distance 1 away from the vertical support member 20 from the center line that runs vertically through the first inclined portion 31 (see FIG. 6). This prevents interference between the part of the other end of the first inclined portion 31 opposite to the vertical support member 20 and the part of one end of the second inclined portion 32 opposite to the vertical support member 20, and prevents the first inclined portion 31 and the second inclined portion 32 from rotating in the opposite direction to the vertical support member 20 with the third bolt 34 as a fulcrum.

[0033] The third bolt hole at the other end of the first inclined portion 31 extends to the end opposite the vertical support member 20 side, forming an opening 35 as shown in Figure 2. This allows the first inclined portion 31 and the second inclined portion 32 to be easily separated by unscrewing the third bolt 34, and the folding scaffolding telescopic bracket 100 can be folded as described below.

[0034] In Example 1, the vertical support member 20 is screwed to the first support piece 11 welded to a first position on the scaffolding support fitting 10, and the inclined support member 30 is screwed to the second support piece 12 welded to a second position on the scaffolding support fitting 10, but this is not necessarily limited to this and modifications are possible as appropriate. For example, the first support piece 11 and the second support piece 12 may not be welded to the scaffolding support fitting 10, and the vertical support member 20 may be screwed directly to the first position on the scaffolding support fitting 10, and the inclined support member 30 may be screwed directly to the second position on the scaffolding support fitting 10. In this case, if the scaffolding support fitting is made of a flat, plate-shaped member, the first support piece 11 and the second support piece 12 can be easily screwed to them.

[0035] Furthermore, the first support piece 11 or the second support piece 12, or both, may be attached to the scaffolding support fitting 10 by a method such as screwing instead of welding.

[0036] Furthermore, while the first rotation prevention protrusion 131 and the second rotation prevention protrusion 331 are both substantially rectangular parallelepiped in shape, this is not necessarily limited to this and can be modified as appropriate. For example, they may be substantially cylindrical, substantially cubic, or any other shape. They may also be formed as multiple protrusions.

[0037] Furthermore, in the first embodiment, the first rotation-preventing protrusion 131 is provided on the first rotation-preventing member 13, and the first rotation-preventing member 13 is welded and fixed to the vertical support member 20, but this is not necessarily limited to this and suitable modifications are possible. For example, the first rotation-preventing protrusion 131 may be provided directly near the end of the vertical support member 20.

[0038] In addition, in the first embodiment, the second rotation-preventing protrusion 331 is provided on the second rotation-preventing member 33, and the second rotation-preventing member 33 is welded and fixed to the second inclined portion 32, but this is not necessarily limited to this and appropriate modifications are possible. For example, the second rotation-preventing protrusion 331 may be provided directly near the end of the first inclined portion 32.

[0039] (How to use the folding scaffolding telescopic bracket) As shown in Figure 1, the folding scaffolding extendable bracket 100 is attached to an iron pipe P that is set up almost vertically by fastening fixtures B attached to vertical support members 20 with the scaffolding support fittings 10 held almost horizontally. In this state, scaffolding can be constructed by placing scaffolding boards, horizontal fall protection nets, or fall protection shelves (not shown) on the scaffolding support fittings 10 of multiple folding scaffolding extendable brackets 100.

[0040] To fold the folding scaffolding telescopic bracket 100, first, as shown in Figure 2, loosen the second bolt 15 and the third bolt 34 to separate the first inclined portion 31 and the second inclined portion 32. Next, loosen the first bolt 14, and as shown in Figure 3, fold the scaffolding support bracket 10 downward (so that it is approximately parallel to the iron pipe P) using the first bolt 14 as a fulcrum.

[0041] The folding scaffolding extendable bracket 100 in the first embodiment of the present invention can be folded downward quickly and easily by simply loosening three bolts. Furthermore, unlike when folding a scaffolding support bracket upward, no mechanism is required to prevent it from falling downward under its own weight, making it possible to realize a low-cost and simple folding scaffolding extendable bracket 100.

[0042] Thus, in Example 1, a foldable folding scaffolding telescopic bracket is provided, a scaffolding support bracket for supporting a scaffolding board; A vertical support member whose one end is provided in a direction substantially perpendicular to the scaffolding support fitting at a first position near one end of the scaffolding support fitting and is rotatable; and an inclined support member, one end of which is inclined relative to the scaffolding support fitting and is rotatable, at a second position near the other end of the scaffolding support fitting, The inclined support member is composed of a first inclined portion having one end rotatably attached to the second position of the scaffolding support bracket, and a second inclined portion attached to the other end of the vertical support member, and the other end of the first inclined portion and one end of the second inclined portion are screwed together in a separable manner at an intermediate portion, thereby making it possible to realize a low-cost, simple foldable scaffolding telescopic bracket.

[0043] In addition, in Example 1, a method for using a folding scaffolding telescopic bracket that can be folded downward, a scaffolding support bracket for supporting a scaffolding board; A vertical support member whose one end is provided in a direction substantially perpendicular to the scaffolding support fitting at a first position near one end of the scaffolding support fitting and is rotatable; An inclined support member is provided at a second position near the other end of the scaffolding support fitting, and one end of the inclined support member is inclined relative to the scaffolding support fitting and is rotatable; and an inclined support member provided at an angle relative to the scaffolding support fitting so that one end of the inclined support member is rotatable at a second position near the other end of the scaffolding support fitting, a folding scaffolding telescopic bracket, wherein the inclined support member is composed of a first inclined portion having one end rotatably attached to the second position of the scaffolding support fitting, and a second inclined portion having one end near the other end attached to the other end of the vertical support member, and the other end of the first inclined portion and one end of the second inclined portion are screwed together in a separable manner at an intermediate portion; The first bolt, the second bolt, and the third bolt are screwed together to fix the vertical support member, the first inclined portion, and the second inclined portion so that the scaffolding support fitting is in a substantially horizontal direction and the vertical support member is substantially vertical downward from the scaffolding support fitting, and a scaffolding board is placed on the scaffolding support fitting to form a scaffold; When no scaffolding is to be formed, the first bolt, the second bolt, and the third bolt are loosened to separate the first inclined portion and the second inclined portion, and the scaffolding support bracket is folded downward, thereby realizing a low-cost, simple folding scaffolding telescopic bracket. [Industrial Applicability]

[0044] The folding scaffolding telescopic bracket and the method for using the folding scaffolding telescopic bracket of the present invention can be widely used in the field of forming scaffolds at construction sites. [Explanation of symbols]
