Description

[Technical field]

[0001] The present invention relates to a mounting bracket to be provided on a frame scaffolding. [Background technology]

[0002] Frame scaffolding is commonly used as temporary scaffolding at construction sites where high-altitude work is required, such as the construction of high-rise structures. Frame scaffolding is constructed by combining and stacking members such as cloth boards and braces on a structure formed by welding and bending steel pipes into a specified gate shape (see, for example, Patent Document 1). When setting up temporary scaffolding and working on it, specified safety measures such as measures to prevent falls and falling objects are taken in accordance with relevant laws and regulations, since work is done at high altitudes. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2003-239530 A Summary of the Invention [Problem to be solved by the invention]

[0004] Regarding the above fall prevention measures, the revised Industrial Safety and Health Regulations (enforced in 2015) added a new rule that the gap between flooring and the building site (vertical members of the building site) must be less than 12 cm on the work floor of the scaffolding, in addition to the previous rule that the gap between flooring materials must be less than 3 cm. Therefore, when the scaffolding is assembled or in use, it takes time for the user to check the above regulations every day. In addition, if the scaffolding is not in the correct position and there is distortion due to the above gap, it becomes difficult to install braces, etc., which can affect the construction period due to reduced work efficiency.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a mounting bracket that has a simple configuration and can maintain gaps between floor materials and between floor materials and building vertical members within specified ranges, thereby improving the management of gaps in temporary scaffolding and the workability of installation work. [Means for solving the problem]

[0006] A mounting bracket to be attached to a framework scaffolding including a building vertical member and a building horizontal member connected to the building vertical member, the mounting bracket comprising: a covering member hooked to the building vertical member and fitted to a covering portion formed on the building horizontal member between a connection portion between the building vertical member and the building horizontal member and a fixed portion of a work floor, the covering member having a covering space capable of covering the covering portion; and a bead connected to the covering member and hooked to the building vertical member, the covering member having a length substantially equal to the covering portion in the material length direction of the building horizontal member, the building horizontal member being insertable therethrough, and formed to be capable of being fitted to the building horizontal member from a downward direction in the installation direction of the building vertical member and capable of being fitted to and removed from the building horizontal member from an upward direction in the installation direction of the building vertical member, the covering member having a length substantially equal to the covering portion in the material length direction of the building horizontal ... The lengths of the covering member and the horizontal member in the longitudinal direction of the building site are approximately the same, and the whisker rib has a connecting piece joined to the covering member, an extension piece continuing from the connecting piece and formed extending in the height direction of the covering member, a first upper piece continuing from the extension piece and formed extending in a direction away from the covering member while close to the building site vertical member, a second upper piece continuing from the first upper piece and formed extending in the external dimension direction of the building site vertical member while close to the building site vertical member, and a third upper piece continuing from the second upper piece, facing the first upper piece across the building site vertical member, and formed extending in a direction close to the covering member while close to the building site vertical member.

[0007] With the above-mentioned configuration, by hooking the tendons of the mounting bracket onto the vertical members and fitting the covering member into the covering part, it becomes possible to cover the horizontal members without gaps in the material length direction of the horizontal members. Therefore, the gaps between the floor members of the scaffolding and between the floor members and the vertical members can be kept within the specified range.

[0008] Furthermore, in the mounting bracket of the present invention, the first upper piece, at the continuation with the extension piece, is bent by approximately 90° in a direction approaching the building vertical member and away from the covering member, the second upper piece, at the continuation with the first upper piece, is bent by approximately 90° in the direction of the external dimensions of the building vertical member approaching the building vertical member, and the third upper piece, at the continuation with the second upper piece, is bent by approximately 90° in a direction approaching the building vertical member and approaching the covering member, and the length of the connection piece in the height direction of the covering member, the length of the extension piece in the height direction of the covering member, the length of the first upper piece in the direction away from the covering member, the length of the second upper piece in the external dimensions direction of the building vertical member, the length of the third upper piece in the direction approaching the covering member, and the external dimensions of the building vertical member may be approximately consistent.

[0009] With the above-mentioned configuration, the mounting bracket can be arranged at a predetermined position on the building vertical member and rotated in a predetermined direction and angle to engage the spine with the building vertical member, thereby making it easy to fit the mounting bracket to the desired position on the covering portion.

[0010] In addition, in the mounting bracket of the present invention, the covering member may have an upper portion formed with a length in the depth direction of the building horizontal member that is approximately the same as the outer dimensions of the covering portion, and one side portion and another side portion extending downward in the installation direction of the building vertical member from both end portions in the depth direction of the building horizontal member of the upper portion, with respect to the material length direction of the building horizontal member of the upper portion, and formed with a length that is approximately the same as the outer dimensions of the building horizontal member.

[0011] With the above-mentioned configuration, the mounting bracket can be fitted to the covering part without any extra gaps in the depth direction of the horizontal member and in the installation direction of the vertical member, which prevents the mounting bracket from falling off due to external forces in those directions and enables the covering part to be firmly covered. Effect of the Invention

[0012] According to the present invention, it is possible to provide mounting brackets which have a simple configuration and can maintain gaps between floor materials and between floor materials and building vertical members within specified ranges, thereby improving the management of gaps in temporary scaffolding and the workability of installation work.

[Figure 7] 4 is a view taken along the arrow A in FIG. 3, showing a mounting state of a modified mounting bracket according to an embodiment of the present invention. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] A mounting bracket 1 according to an embodiment of the present invention will now be described with reference to Figs. First, as shown in FIG. 1, a mounting bracket 1 according to this embodiment is composed of a covering member 10 having a covering space 11 and a strand 12 joined to the covering member 10. In FIG. 1, the width direction in the mounting direction of mounting bracket 1 is defined as the X direction, the depth direction as the Y direction, and the height direction as the Z direction.

[0015] The covering member 10 is composed of a plate-shaped upper portion 10a formed extending in the X and Y directions, and a plate-shaped one-side side portion 10b (hereinafter, side portion 10b) and other-side side portion 10c (hereinafter, side portion 10c) provided at both ends of the upper portion 10a in the Y direction and formed extending from the lower surface of the two surfaces of the upper portion 10a facing the Z direction. The side portion 10b is formed extending downward in the Z direction from the end portion in front of the upper portion 10a in the Y direction in FIG. 1(a), and the side portion 10c is formed extending downward in the Z direction from the end portion on the other side in the Y direction relative to the one end portion of the upper portion 10a where the side portion 10b is formed. With the above configuration, the covering member 10 is formed with an inverted U-shaped cross section that opens downward in the Z direction in the X direction.

[0016] The upper portion 10a is formed to be longer in the X direction and shorter in the Z direction, and the side portions 10b, 10c are formed to be longer in the X direction and shorter in the Y direction. The length in the Z direction of the upper portion 10a, which corresponds to each thickness, and the length in the Y direction of the side portions 10b, 10c are approximately the same, and the lengths in the X direction of the upper portion 10a and the side portions 10b, 10c, which correspond to each width, are approximately the same. Of the two faces of the upper portion 10a facing in the Z direction in FIG. 1, the face disposed at the top is referred to as the top face 10d.

[0017] The covering member 10 has sufficient strength against external forces in the compression direction (X direction) in the mounting orientation of the mounting bracket 1. For example, steel is used as the material. In this embodiment, the covering member 10 is formed from a single member, but the configuration is not limited to this embodiment as long as the covering member 10 has the desired performance and predetermined durability. For example, the upper portion 10a and the side portions 10b and 10c may be formed from different members, and the covering member 10 may be formed by joining these members.

[0018] The whisker 12 is joined to one outer surface 10e (hereinafter, joint surface 10e) facing the X direction of the side portion 10b of the covering member 10. The whisker 12 is made of a single steel material, and is formed by bending it at a predetermined position at a predetermined angle and direction. The whisker 12 is formed from a connection piece (welded piece) 13, an extension piece 14, and a first upper piece 16, a second upper piece 17, and a third upper piece 18 as a fitting portion 15, which are continuous from the joint with the side portion 10b.

[0019] Furthermore, the whisker 12 has a predetermined bending strength such that the bent portions between the pieces do not easily change in response to an external force. The outer dimensions of the whisker 12 are constant and approximately equal to the length (thickness) of the side portion 10b in the Y direction. Note that as long as each piece has a predetermined bending strength, the configuration is not limited to that of this embodiment. For example, the outer dimensions may be changed for each bent portion of the whisker 12.

[0020] The connection piece 13 is formed by being joined to the joining surface 10e. The side portion 10b and the connection piece 13 are joined by welding the portions where they are to be attached to each other. Note that this embodiment is not limited to this embodiment as long as a predetermined durability is obtained at the joint. For example, the joint may be made by a screw, a metal adhesive, or other joining method, and the covering member 10 and the strands 12 may be formed from a single member as long as the mounting bracket 1 can obtain the desired performance.

[0021] Furthermore, since the connection piece 13 is joined to the joining surface 10e, it has sufficient strength in the compression direction (X direction) like the covering member 10. Note that the configuration of this embodiment is not limited to cases where a compressive force is not applied to the connection piece 13 when the compressive force is applied to the covering member 10. For example, there is a case where the connection piece 13 is joined to one outer surface of the side portion 10b facing the Y direction.

[0022] The extension piece 14 is provided so as to extend continuously from the upper end in the Z direction of the connection piece 13. In addition, the extension piece 14 is provided perpendicular to the surface of the upper portion 10a facing in the Z direction. The first upper piece 16 extends continuously from the upper end of the extension piece 14 in the Z direction, and is bent at approximately 90° in the opposite direction to the covering member 10 in the X direction. The second upper piece 17 extends continuously from one of the two X-direction ends of the first upper piece 16 that is not continuous with the extension piece 14, and is bent approximately 90° toward the side portion 10c in the Y direction. The third upper piece 18 extends continuously from one of the Y-direction ends of the second upper piece 17 that is not continuous with the first upper piece 16, and is bent approximately 90° in a direction approaching the covering member 10 in the X-direction.

[0023] 1(a) and 1(b), the Z-direction length of the connecting piece 13, the Z-direction length of the extension piece 14, the X-direction length of the first upper piece 16, the Y-direction length of the second upper piece 17, and the X-direction length of the third upper piece 18 are approximately the same. Also, as shown in Figs. 1(a) and 1(b), the X-direction position of the end of the third upper piece 18 that is not continuous with the second upper piece 17 and the joint between the covering member 10 and the connecting piece 13 are approximately the same in the X-direction when viewed from the front.

[0024] The first upper piece 16, the second upper piece 17, and the third upper piece 18, which are provided successively, form a U-shaped fitting portion 15 that opens in a direction approaching the covering member 10 in the X direction. The fitting portion 15 also forms an enclosure portion 19 that has an opening and is surrounded.

[0025] In addition, as long as the desired performance is obtained, the configuration of each bent portion of the whisker 12 is not limited to that of this embodiment. For example, the connection piece 13 may be joined to the side portion 10b, or the connection piece 13 may be joined to the side portion 10c, and the whisker 12 may be appropriately bent to form each piece continuing from the connection piece 13.

[0026] Next, a method for attaching the above-described mounting bracket 1 will be described with reference to FIGS. As shown in Fig. 2, the framework scaffolding 2 in this embodiment is formed by combining a site 20 consisting of site vertical members (handrail posts) 21 and site horizontal members (scaffolding site) 22, and stacking them in sequence in the Z direction. In the formed site 20, a plurality of cloth boards 24 constituting a work floor 23 are sequentially fixed to the site horizontal members 22 by engaging fixing parts 25 provided at both ends of the cloth boards 24 in the installation direction with the site horizontal members 22, thereby forming the framework scaffolding 2. The area between the fixing portion 25 of the horizontal member 22 adjacent to the vertical member 21 and the connection portion 26 between the vertical member 21 and the horizontal member 22 is configured as a covering portion 27 that is covered by the mounting bracket 1. Based on the installation direction of the mounting bracket 1 described later and the directions defined in Figure 1, the direction in which the horizontal member 22 extends from the connection portion 26 is defined as the X direction, the installation extension direction of the cloth board 24 is defined as the Y direction, and the direction in which the vertical member 21 extends is defined as the Z direction. The site 20 (site vertical members 21 and site horizontal members 22) and the work floor 23 that constitute the framework scaffolding 2 are made of steel materials having a desired strength, and the cross-sectional shapes of the site vertical members 21 in the X direction and the site horizontal members 22 in the Z direction form circular shapes. In addition, the length of the covering portion 27 in the X direction and the length of the covering member 10 in the X direction are approximately the same.

[0027] The Z-direction length of the connection piece 13 and the extension piece 14, the X-direction length of the first upper piece 16 and the third upper piece 18, and the Y-direction length of the second upper piece 17 in Fig. 1 are approximately equal to the diameter of the building site vertical member 21 in Figs. 2 to 5, and are formed so that the building site vertical member 21 can be stored in the enclosure part 19. The length of each part of the ridges 12 is not limited to the configuration of this embodiment as long as the mounting bracket 1 can be easily attached to the covering part 27. For example, the Y-direction length of the second upper piece 17 that sandwiches the building site vertical member 21 may be formed slightly larger than the X-direction diameter of the building site vertical member 21.

[0028] 1 and the diameter of the covering portion 27 in Figures 2 to 5. The lengths of the covered space 11 in the Y and Z directions are not limited to the configuration of this embodiment as long as the mounting bracket 1 can be easily attached to the covering portion 27. For example, the lengths of the covered space 11 in the Y and Z directions, or both, may be formed slightly larger than the diameter of the covering portion 27. Furthermore, the covering member 10 is not limited to the configuration of this embodiment as long as it can cover the covering portion 27. For example, the cross-sectional shape of the surface of the upper portion 10a facing the X direction in FIG.

[0029] A method of attaching the mounting bracket 1 in this embodiment to the covering portion 27 will be described. First, as shown in Fig. 2, the upper surface 10d of the upper portion 10a of the covering member 10 is opposed to the surface of the building vertical member 21 on which the connection portion 26 is provided. In addition, with the above-mentioned configuration, the extension piece 14 and the second upper piece 17 are close to the outer surface of the building vertical member 21. As shown in FIG. 2, the second upper piece 17 is disposed upward in the Z direction from the upper end of the covering portion 27 in the Z direction at a distance corresponding to the length of the first upper piece 16 and the third upper piece 18 .

[0030] In the above configuration, the mounting bracket 1 arranged on the site vertical member 21 is rotated about the second upper piece 17 in the X direction, from the direction in which the site horizontal member 22 extends, downward in the Z direction by approximately 90°. This rotation causes the covering member 10 to move so as to cover the covering portion 27 from above, and the covering portion 27 is covered by storing it in the covered space 11. With the above configuration, as shown in Figures 3 to 5, the tendons 12 are hooked onto the site vertical member 21 and disposed on the site vertical member 21, and the covering member 10 is covered by the covering portion 27 to attach the mounting bracket 1 to the frame scaffolding 2.

[0031] 5, the building site vertical members 21, 21 are disposed via the building site horizontal members 22 to which the fixing parts 25 are engaged at both ends of the X direction of the working floor 23, and the covering parts 27, 27 are provided at both ends of the X direction of the working floor 23. Therefore, the mounting brackets 1, 1 are attached to both ends of the X direction of the working floor 23 by the above-mentioned mounting method.

[0032] In this embodiment, the mounting bracket 1 is attached to the scaffolding frame 2 with the extension piece 14, the first upper piece 16, the second upper piece 17, and the third upper piece 18 of the ridges 12 being appropriately close to the vertical members 21. The shape of the ridges 12 is not limited to this embodiment as long as the mounting bracket 1 can exhibit the desired performance. For example, the bent portion between the first upper piece 16 and the second upper piece 17 and the bent portion between the second upper piece 17 and the third upper piece 18 may be formed to substantially match the cross-sectional shape of the vertical members 21.

[0033] Next, the operation and effect of the mounting bracket according to the embodiment of the present invention described above will be described with reference to FIGS. 2 and 3, in this embodiment, the upper surface 10d of the mounting bracket 1 is opposed to the surface of the building vertical member 21 on which the connection portion 26 is provided, and the second upper piece 17 is arranged from the Z-direction upper end of the covering portion 27 upward in the Z direction at a distance corresponding to the length of the first upper piece 16 and the third upper piece 18. In the above configuration, the mounting bracket 1 arranged on the building vertical member 21 is rotated approximately 90° in the X direction around the second upper piece 17 downward in the Z direction from the direction in which the building horizontal member 22 extends. With the above mechanism, the mounting bracket 1 can be easily fitted to a predetermined position of the covering portion 27 as shown in FIG.

[0034] As shown in Fig. 5, the covering parts 27, 27 provided at both ends of the work floor 23 in the X direction have a length in the X direction that is approximately equal to the length in the X direction of the covering member 10 that covers the covering part 27, and the mounting brackets 1, 1 are attached to both ends of the work floor 23 in the X direction. With the above configuration, the mounting brackets 1, 1 can be fitted to the horizontal member 22 in the X direction without any extra gaps. Therefore, the gaps between the work floors 23 and between the fixing parts 25 adjacent to the vertical members 21 and the vertical members 21 can be kept within the specified range, and the gaps of the temporary scaffolding can be managed and the workability of the installation work can be improved.

[0035] 3 to 5, the lengths of the covered space 11 in the Y and Z directions are substantially equal to the diameter of the covering portion 27, so that the mounting bracket 1 can be fitted into the covering portion 27 without any extra gaps in the Y and Z directions. This prevents the mounting bracket 1 from falling off due to an external force in those directions, and enables the covering portion 27 to be tightly covered.

[0036] 3 and 5, the mounting bracket 1 has a U-shaped fitting portion 15 that opens in a direction approaching the covering member 10 in the X direction, and the fitting portion 15 is disposed adjacent to the building site vertical member 21. With the above-mentioned configuration, the mounting bracket 1 can prevent the mounting bracket 1 from falling off due to an external force in the Y direction, and can firmly cover the covering portion 27.

[0037] Although an embodiment of the mounting bracket 1 according to the present invention has been described above, the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit of the invention. For example, in the case where baseboards 28 are provided at both ends of the work floor 23 in the X direction as a falling object prevention mechanism as shown in Fig. 6 and Fig. 7, the covering member 10 is provided at the bottom of the girder side portion 28a. The ridges 12 are attached to the building site vertical members 21 located on the outside of the gable side portion 28b. The fitting portion 15 and the baseboard fixing portions 29, 29 are provided at different positions in the Z direction of the building site vertical members 21. With the above configuration, the mounting bracket 1 can be attached to the frame scaffolding 2 without interfering with the installation of the baseboard 28, so that it is possible to easily achieve both falling object prevention measures and gap countermeasures (fall prevention measures) between the work floors 23 and between the work floor 23 and the building site vertical members 21.

[0038] Also, in the above embodiment, the third upper piece 18 is configured as the tip of the ribs 12, but the ribs 12 can be extended continuously downward in the Z direction from the tip of the third upper piece 18 that is not connected to the second upper piece 17 and joined to the side portion 10c to form a configuration similar to that of the connecting piece 13. With this configuration, a mounting bracket 1 can be formed in which the covering member 10 and the ribs 12 are integrated via the sides 10b, 10c. [Explanation of symbols]
