Abstract

The present disclosure aims to provide scaffolding that can be attached even to lightweight pillars. [Solution] The present disclosure relates to a scaffolding device comprising a rod body that penetrates a columnar object in the circumferential direction, a locking body that is locked to the rod body and restricts the longitudinal movement of the rod body, and a scaffolding body that is fixed to the side of the columnar object using the rod body or the locking body.

Description

[Technical Field]

[0001] The present disclosure relates to scaffolding for workers climbing utility poles. [Background technology]

[0002] A first prior art technique is a scaffold bolt for attaching scaffolding to the side of a columnar object (see, for example, Non-Patent Document 1). When using a scaffold bolt, a scaffold socket is provided in the column during the column manufacturing process. The scaffold socket is a threaded hole into which the scaffold bolt can be fixed, and in the case of a steel pipe column, it is attached by welding. At the site, the scaffolding can be constructed by attaching the scaffold bolt to the scaffold socket.

[0003] The second type of prior art is band scaffolding (see, for example, Non-Patent Document 1). Band scaffolding is constructed by wrapping a flexible band around a pillar. Band scaffolding can be constructed at the height at which the flexible band is wrapped, so it can be applied to pillars that do not have scaffolding sockets. Scaffolding hardware and flexible bands are generally made of metal materials. [Prior art documents] [Non-patent literature]

[0005] Lighter columns have been proposed, such as by using thinner plates or materials other than metal, such as resin. However, reducing the weight of columns makes them weaker against loads. In the first conventional technology, all of the load on the scaffolding is concentrated at the scaffolding socket, so it is desirable to reduce this concentration.

[0006] The second conventional technology requires checking, marking, and fine-tuning the position during installation, which makes the installation process time-consuming, taking approximately eight times longer than the first conventional technology.

[0007] The present disclosure aims to provide scaffolding that can be attached even to lightweight pillars. [Means for solving the problem]

[0008] In order to achieve the above-mentioned objective, the scaffolding device of the present disclosure comprises a rod body that penetrates the circumferential direction of a columnar object, a locking body that is locked to the rod body and restricts the longitudinal movement of the rod body, and a scaffolding body that is fixed to the rod body or the locking body.

[0009] A columnar object equipped with the scaffolding device of the present disclosure has through holes at equidistant positions in the longitudinal direction, through which the rod body can pass.

[0010] The method of installing the scaffolding device of the present disclosure comprises the steps of passing the rod body of the scaffolding device of the present disclosure through a columnar object having through holes at equidistant positions in the longitudinal direction, and fixing the scaffolding body to the columnar object by fixing the locking body to the rod body.

[0011] The rod body and the scaffolding body may be a single long scaffolding bolt having a bolt portion formed at the tip, and the locking body may include a nut that engages with the bolt portion.

[0012] The scaffold may be one side of an L-shaped rigid body. In this embodiment, the other side of the L-shape may be fixed to the side surface of the columnar object using the rod.

[0013] The scaffolding body may be a scaffolding bolt. In this embodiment, the scaffolding bolt may be connected to a rigid body that fixes the rod body to the columnar object.

[0014] The above disclosures can be combined as much as possible. [Effects of the Invention]

[0015] According to the present disclosure, it is possible to provide scaffolding that can be attached even to lightweight pillars. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below. These implementation examples are merely illustrative, and the present disclosure can be implemented in various forms with various modifications and improvements based on the knowledge of those skilled in the art. Note that components with the same reference numerals in this specification and drawings indicate the same components.

[0018] (Scaffolding bolts) An example of how a scaffold bolt is attached is shown in Figure 1. The scaffold bolt 31 described in the first prior art supports the load on the scaffold at a single point, the scaffold socket 84. This makes it easy for a moment load to be applied to the columnar object 81. This creates a strength bottleneck when trying to reduce the weight of the column by using thinner plates or lighter materials.

[0019] (Summary of the Invention) 2 shows an example configuration of a scaffolding device according to the present disclosure. A columnar object 81 is provided in advance with through holes 82 and 83 through which a rod 11 can pass. The through holes 82 and 83 are provided at positions equidistant in the longitudinal direction. When the columnar object 81 is a steel pipe column, the through holes 82 and 83 are provided in the steel pipe column. The columnar object 81 is not limited to a steel pipe column, and may be made of resin, concrete, or wood.

[0020] The scaffolding device of the present disclosure comprises a rod body 11, a pair of locking bodies 12 and 13, and a scaffolding body 14. The rod body 11 penetrates the circumferential direction of a columnar object 81. In this embodiment, an example is shown in which the longitudinal direction of the columnar object 81 coincides with the y-axis direction, and the longitudinal direction of the rod body 11 is arranged in the x-axis direction of the circumferential direction of the columnar object 81.

[0021] The pair of locking bodies 12 and 13 are locked to the rod body 11 and restrict movement of the rod body 11 in the x-axis direction, which is the longitudinal direction of the rod body 11. For example, the rod body 11 can be a bolt, and the locking bodies 12 and 13 can be nuts. The locking bodies 12 and 13 may have the same mechanism, or different mechanisms may be used.

[0022] The scaffolding body 14 is a member that is fixed to or can be fixed to the rod body 11 or the locking body 12. In this embodiment, an example is shown in which the scaffolding body 14 is used as a scaffolding, but the use is arbitrary, and any shape suitable for the use can be adopted.

[0023] The method for attaching the scaffolding device of this embodiment includes the steps of inserting the rod 11 provided in the scaffolding device of the present disclosure into a columnar object 81 having through-holes 82 and 83 formed therein, and fixing the locking members 12 and 13 to the rod 11, thereby fixing the scaffolding device 14 to the columnar object 81. In this way, the scaffolding device 14 can be attached to the columnar object 81.

[0024] When a load W1 is applied to the scaffolding 14, a load W2 is applied to the through-hole 82 in the same direction as the load W1. At this time, in the present disclosure, a load W3 is applied to the through-hole 83 by the rod 11 in the opposite direction to the load W2. In this manner, in the present disclosure, the load W1 acting on the scaffolding 14 is supported at two points, the through-holes 82 and 83. As a result, the present disclosure significantly reduces the load due to the moment, making it possible to attach the scaffolding 14 to even a lightweight columnar object 81.

[0025] In the first conventional technology, in addition to the step of drilling holes in the columnar object 81, a step of joining the scaffolding receptacle 84 to the columnar object 81 was required. In this regard, in the present disclosure, the step of joining the scaffolding receptacle 84 is not required, and only the step of drilling the through holes 82 and 83 in the columnar object 81 is required, thereby reducing the cost of the columnar object 81.

[0026] Furthermore, in the present disclosure, since the rod 11 is attached to the through-holes 82 and 83 provided in advance in the columnar object 81, there is no need to check, mark, or fine-tune the position during attachment. Therefore, attachment can be completed simply by passing the rod 11 through the columnar object 81 and engaging the engaging bodies 12 and 13 with the columnar object 81, which saves time for the attachment work and improves convenience.

[0027] (First embodiment) 3 shows an embodiment of the scaffolding device of the present disclosure. In the scaffolding device of this embodiment, the rod body 11 and the scaffolding body 14 are a single long scaffolding bolt 91. The long scaffolding bolt 91 is provided with a flange 92 that functions as the locking body 12 at the boundary between the rod body 11 and the scaffolding body 14. In this embodiment, a nut 93 functions as the locking body 13.

[0028] The flange 92 makes the outer diameter of the long scaffolding bolt 91 larger than the inner diameter of the through hole 82 to prevent the long scaffolding bolt 91 from entering the through hole 82. The flange 92 is any member that can be fixed to the position of the long scaffolding bolt 91 in the through hole 82, and a nut can be used, for example. The flange 92 may be a modified long scaffolding bolt 91. As shown in the figure, the flange 92 may be provided around the entire circumference of the long scaffolding bolt 91, or may be provided around a portion of the circumference of the long scaffolding bolt 91. The long scaffolding bolt 91 has a bolt portion 91T at its tip that engages with a nut 93.

[0029] As shown in Fig. 4, the tip of the long scaffolding bolt 91 is passed through the through-holes 82 and 83, and the tip of the long scaffolding bolt 91 is fastened with a nut 93. This fixes the long scaffolding bolt 91 to the columnar object 81. Washers 94 and 95 may be provided here to relieve surface pressure and prevent subsidence or damage to the components. The washer 94 is placed between the flange 92 and the columnar object 81. The washer 95 is placed between the nut 93 and the columnar object 81.

[0030] In this embodiment, installation is easy because the scaffolding can be constructed simply by passing the long scaffolding bolts 91 through the through holes 82 and 83 and fastening them with nuts 93. In addition, the number of parts required to construct the scaffolding is small, so it can be realized at low cost.

[0031] (Second embodiment) Figure 5 shows an embodiment of the scaffolding device of the present disclosure. In this embodiment, the scaffolding body 14 is a scaffolding hardware 22. The scaffolding hardware 22 is a rigid body having an L-shape. One side of the L-shape of the scaffolding hardware 22 functions as the scaffolding body 14. The square-root round head bolt 21 has a bolt portion 21T at its tip that engages with a nut 93, and the external shape of the base of the head side is square.

[0032] As shown in FIG. 6 , the scaffolding hardware 22 is arranged so that the other side of its L-shape is along the side surface of the columnar object 81. The scaffolding hardware 22 has a through hole 23 on the other side of its L-shape, through which the square-neck round head bolt 21 is passed. The square-neck round head bolt 21 is passed through the through hole 23 and further through the through holes 82 and 83 of the columnar object 81. Then, the bolt portion 21T of the square-neck round head bolt 21 is tightened with a nut 93. As a result, the other side of the L-shape of the scaffolding hardware 22 is fixed to the side surface of the columnar object 81 using the square-neck round head bolt 21.

[0033] This embodiment may also be provided with washers 94 and 95 that relieve surface pressure and prevent components from sinking or being damaged. Washer 94 is placed between the head of square root round head bolt 21 and columnar object 81. Washer 95 is placed between nut 93 and columnar object 81. Furthermore, providing washer 94 can prevent interference between the square root portion of square root round head bolt 21 and columnar object 81.

[0034] (Third embodiment) An embodiment of the scaffolding device of the present disclosure is shown in Figure 7. In the scaffolding device of this embodiment, the rod body 11 is a square root round head bolt 21, and the scaffolding body 14 is a scaffolding bolt 31, which are connected by a scaffolding bolt mounting hardware 32. The scaffolding bolt mounting hardware 32 is a rigid body that connects the rod body 11 and the scaffolding body 14, and in this embodiment, it has a through hole 36 for mounting the scaffolding bolt 31 and a through hole 37 for passing the square root round head bolt 21 through.

[0035] As shown in Fig. 8, the scaffolding bolt 31 has a bolt portion at its tip that engages with a nut 33, and can be fixed to the scaffolding bolt mounting hardware 32 by the nut 33. The scaffolding bolt 31 may have a flange 35 similar to the flange 92 described in the first embodiment.

[0036] The scaffolding bolt 31 is passed through the through hole 36, and the scaffolding bolt 31 is fixed to the scaffolding bolt mounting hardware 32 with a nut 33. Then, the square root round head bolt 21 is passed through the through hole 37, and further through the through holes 82 and 83 of the columnar object 81. Then, the bolt portion 21T of the square root round head bolt 21 is fastened with a nut 93. As a result, the scaffolding bolt mounting hardware 32 to which the scaffolding bolt 31 is connected is fixed to the columnar object 81.

[0037] This embodiment may also include a washer 95. The washer 95 is disposed between the nut 93 and the columnar object 81 and has a round hole. In addition, a washer 34 may be disposed between the nut 33 and the scaffolding bolt mounting hardware 32.

[0038] (Other embodiments) The scaffolding 14 is not limited to use as a scaffolding. By changing the shape of the scaffolding 14 to a structure for attaching equipment, it can also be used to attach other equipment (such as a radio antenna). [Explanation of symbols]
