  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, scaffold safety band attachments and advance handrail support members according to embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

(First embodiment)
<Configuration of safety band attachment for scaffold>
The structure of the scaffold safety band attachment 1 according to the first embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 4.

  The scaffold safety band attachment 1 is used to attach a safety band to a scaffold. The scaffold safety band attachment 1 includes an attachment member 2 and a metal fitting 3.

  The attachment member 2 is attached to the member which comprises a scaffold. A member constituting a scaffold to which the attachment member 2 is attached is typically a building site. The attachment member 2 includes a tubular portion 21 and an attachment plate portion 22.

  The tubular portion 21 is tubular, and includes an open groove 211 that is formed along the circumferential direction while opening the inside to the outside at the bottom. The tubular portion 21 is attached to the end of the scaffolding pipe coaxially with the scaffolding pipe. The scaffold pipe attached to the tubular portion 21 is typically used as a handrail.

  The mounting plate part 22 includes a side wall part 222 standing upward from the tubular part 21, an upper wall part 223 extending laterally from the upper end of the side wall part 222, and a distal end of the upper wall part 223 in the extending direction. And a side wall 224 extending downward from the side wall.

  The side wall part 222 is provided integrally with the tubular part 21 along the front-rear direction that is the axial direction of the tubular part 21, and faces the side wall part 224. The side wall 222 is provided with a rectangular window hole 225 penetrating in the thickness direction above the open groove 211. An abutting portion 226 is formed below the window hole 225 of the side wall portion 222 so as to abut an engaging portion 31 of the metal fitting 3 to be described later.

  The metal fitting 3 is U-shaped, is detachably suspended from the tubular portion 21, and is movable in the axial direction of the tubular portion 21 and the circumferential direction of the tubular portion 21. The metal fitting 3 includes a locking part 31 and an engaging part 32.

  The locking portion 31 includes a protruding portion 311 that protrudes inward and makes point contact with the tubular portion 21. The locking portion 31 can be locked to the tubular portion 21 so as to be movable along the axial direction of the tubular portion 21 and the circumferential direction of the tubular portion 21 by the protrusion portion 311 coming into contact with the tubular portion 21. It is formed in a size that can be inserted into the hole 225. The interval between the opposing locking portions 31 is smaller than the outer diameter of the tubular portion 21. When the locking portion 31 moves on the tubular portion 21 along the circumferential direction of the tubular portion 21, the locking portion 31 abuts on the abutting portion 226 and is further defined to rotate in the circumferential direction. The locking part 31 penetrates the window hole 225 when it moves along the circumferential direction of the tubular part 21 in a state of floating by a predetermined distance from the tubular part 21.

  When the engaging portion 31 is engaged with the tubular portion 21, the engaging portion 32 is opposed to the tubular portion 21 with a predetermined interval so that a hook of a safety belt (not shown) can be engaged.

<Mounting method of safety band attachment for scaffold>
The attachment method of the safety band attachment 1 for scaffolds concerning the 1st Embodiment of this invention is demonstrated in detail below, referring FIGS. 5-8.

  First, as shown in FIG. 5, the side wall portion 224 of the attachment member 2 of the scaffold safety band attachment 1 is attached to each of the building sites 4. The side wall part 224 is attached to the building site 4 using an attachment member 8 (see FIG. 8) such as a clamp. The building place 4 is erected on the ground with a predetermined interval.

Next, as shown in FIG. 5, the scaffolding pipe 6 serving as a handrail is attached to the tubular portion 21 of the attachment member 2 attached to the adjacent building 4 via the joint 5. The tubular portion 21 is
Since it has the same diameter as the scaffolding pipe 6, when it is connected to the scaffolding pipe 6 via the joint 5, the scaffolding pipe 6 and the tubular portion 21 can form a handrail without unevenness.

  Next, one locking part 31 of the metal fitting 3 is caused to enter the inside of the tubular part 21 through the open groove 211, and the other locking part 31 is passed through the window hole 225.

  Next, when the metal fitting 3 is rotated clockwise as viewed from the rear, as shown in FIG. 6, the locking portion 31 that has penetrated the window hole 225 is pulled out from the window hole 225.

  Next, the metal fitting 3 is rotated clockwise until both the locking portions 31 of the metal fitting 3 are positioned above the open groove 211, and then external loads such as rotational force applied to the metal fitting 3 are removed. As shown in FIG. 7, the locking portion 31 is locked to the tubular portion 21. In this state, the engaging portion 32 has a predetermined distance R and faces the tubular portion 21.

  In the state shown in FIG. 7, the metal fitting 3 can move upward by a predetermined distance R because the hook 71 of the safety belt 7 is not engaged with the engaging portion 32. Accordingly, in the state shown in FIG. 7, by moving the metal fitting 3 upward and rotating it in the circumferential direction of the tubular portion 21, the locking portion 31 can be inserted into the window hole 225 and the locking portion 31 is moved to the window. The hole 225 can be extracted to the outside.

  Next, as shown in FIG. 8, the safety belt 7 is attached to the metal fitting 3 by engaging the hook 71 of the safety belt 7 with the engaging portion 32. Thereby, the safety belt | band | zone 7 can be attached to a handrail via the safety band attachment tool 1 for scaffolds.

  When the worker of the scaffold with the safety belt 7 attached walks and moves on the scaffolding plate, the metal fitting 3 attached with the safety belt 7 moves on the handrail following the movement of the worker. At this time, since the scaffold pipe 6 and the tubular portion 21 can form a handrail without unevenness, the metal fitting 3 can move smoothly on the handrail.

Therefore, when the metal fitting 3 is rotated in the circumferential direction of the tubular portion 21 in the state shown in FIG. 8, the locking portion 31 moves on the tubular portion 21 while rotating in the circumferential direction of the tubular portion 21. In this case, the metal fitting 3 is restricted from moving further in the rotational direction because the locking portion 31 comes into contact with the contact portion 226. Further, the locking portion 31 is not inserted into the window hole 225. Thus, in a state where the safety belt 7 is attached to the metal fitting 3, the metal fitting 3 cannot be removed from the attachment member 2, so that the safety of the operator can be ensured.

And moving without contacting the tubular portion 21. Even when the contact portion 226 rotates in the circumferential direction with the locking portion 31 slightly lifted from the tubular portion 21, the locking portion 31 contacts when the hook 71 is engaged with the metal fitting 3. It is formed at a height.

When it is desired to remove the metal fitting 3 from the mounting member 2, the safety band 7 is removed from the metal fitting 3, the metal fitting 3 is moved upward and rotated in the circumferential direction of the tubular portion 21, and one locking portion 31 is moved. The metal fitting 3 may be pulled away from the mounting member 2 while being inserted into the window hole 225 and with the other locking portion 31 inserted into the inside of the tubular portion 21 from the open groove 211. Thereby, the metal fitting 3 can be freely removed from the attachment member 2, and the metal fitting 3 which is not used can be prevented from being left on the scaffold.

  In addition, the metal fitting 3 is suspended from the tubular portion 21 after the scaffold pipe 6 is attached to the tubular portion 21, but the scaffold pipe 6 may be attached to the tubular portion 21 after the metal fitting 3 is suspended from the tubular portion 21. .

  Thus, according to this embodiment, the tubular tubular portion 21 attached to the tip of the scaffolding pipe 6 coaxially with the scaffolding pipe 6, and the attachment provided on the tubular portion 21 and attached to the member constituting the scaffolding The mounting member 2 including the plate portion 22, the locking portion 31 that can be locked to the tubular portion 21 movably along the axial direction of the tubular portion 21, and the locking portion 31 locked to the tubular portion 21. And an engagement portion 32 that is opposed to the tubular portion 21 with a gap and that can be engaged with the safety belt 7, and has a fitting 3 that is detachably suspended from the tubular portion 21. As a result, an increase in transportation cost can be suppressed, and it can be easily installed and manufactured at low cost.

  Moreover, according to this embodiment, the tubular part 21 is provided with the open groove 211 that opens the inside formed along the circumferential direction in the lower part to the outside, and the locking part 31 moves along the circumferential direction of the tubular part 21. The mounting plate portion 22 is provided above the tubular portion 21 with the side wall portion 222 standing above the open groove 211 of the side wall portion 222 and penetrates in the plate thickness direction to insert the locking portion 31. The side wall 222 is provided below the window hole 225 and has a contact portion 226 with which the locking portion 31 that moves on the tubular portion 21 along the circumferential direction contacts. Thus, in a state where the scaffold is assembled, the metal fitting 3 can be easily attached to or removed from the tubular portion 21, and when the safety band 7 is connected to the metal fitting 3, the metal fitting 3 is removed from the tubular portion 21. Does not fall off It is possible to ensure the safety of the workers in.
