Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting device for a pillar for mounting a safety rope, which is used when a safety rope is stretched on structural members such as beams, purlins and scaffolds at a construction site.

[0002]

[Prior Art]

 When working in high places, the safety of workers is ensured by laying safety ropes along the walking paths of workers. In the roof construction work of the building shown in FIG. 5, etc., columns 2 are erected at appropriate places of the structural member 1 which is an I-shaped steel as a main material, and ropes such as ropes 3 are attached to these columns 2 ,. When an operator moves on the structural member 1, the rope 3 is used as a handrail to prevent a fall accident or the like.

[0003] Conventionally, as the mounting device A for erecting the pillar 2 on the structural member 1, the one shown in Fig. 6 has been used. This mounting device A has a structure in which a columnar fastener 5 having a split shape is fixed to the U-shaped metal fitting 4, and a fastening bolt 6 is provided on the U-shaped metal fitting 4. When mounting the mounting device A to the structural member 1 made of I-shaped steel, the U-shaped metal fitting 4 is fitted into the flange 1a of the structural member and the tightening bolt 6 is tightened. Further, when fixing the column 2 to the attachment device A, the column fastener 5 into which the column 2 is fitted is tightened with bolts and nuts 7.

[0004]

[Problems to be solved by the device]

 However, in the conventional mounting device A, not only is there a risk that the column 2 will slide down if the column fastener 5 becomes loose or the clamping force is insufficient for some reason, and the column 2 must be fixed when the column 2 is fixed. You will be forced to carry out the difficult and dangerous work of supporting your hand and tightening the bolts and nuts 7. Further, in order to mount the column 2 without wobbling, it is necessary to fix the two columns of the column 2 with the attachment devices A and A attached to the upper and lower flanges 1a and 1b of the I-shaped steel as shown in FIG. Moreover, since it is necessary to perform the work from above the structural member 1 at a high place, the mounting device A is mounted on the flange 1b on the lower side of the structural member 1 or the support column 2 is fixed to the mounting device A. At the same time, it was extremely dangerous for the worker to lean over the structural member 1 and tighten the tightening bolts 6 and bolts / nuts 7 below the upper surface of the structural member 1, which was extremely dangerous. In addition, there was the annoyance that many bolts had to be tightened.

The present invention has been made in view of the above circumstances, and there is no risk of the pillars sliding down, and it is possible to easily and safely perform the mounting work to the structural members and the fixing work of the pillars. It is an object of the present invention to provide a support device for a safety rope that can be used.

【Example】

 FIG. 1 shows a mounting device A according to an embodiment of the present invention in use. This mounting device A is made by subjecting a single rectangular steel plate to necessary processing such as predetermined bending and drilling, and the pair of mounting portions 11 and 12 and the respective mounting portions 11 and 12 are formed. , A pair of leg portions 13 and 14 which are individually raised from the upper and lower portions, an upper plate portion 15 extending between upper end portions of the pair of leg portions 13 and 14, and a hole portion 16 formed in the upper plate portion 15. , A support fitting B having bolt insertion holes 17 and 18 (see FIG. 2) formed in the legs 13 and 14, a tightening bolt 19 inserted into the bolt insertion holes 17 and 18, and a tightening bolt 19. And a nut 20 screwed to the attached bolt 19. The pair of mounting portions 11 and 12 are formed in a U-shaped symmetrical shape, and the lower end portions of the pair of mounting portions 11 and 12 are integrally provided with inwardly extending intake guide pieces 21 and 22. Further, when the mounting portions 11 and 12 are attached to a structural member described later, the upper plate portion 15 is positioned so as to be spaced apart from the upper surface of the structural member 1. Furthermore, the hole portion 16 has a diameter dimension that is not smaller than the outer diameter dimension of the support column 2, but the preferable diameter dimension is as small as possible within a range in which the support column 2 can be easily inserted.

In FIG. 1, B is a support metal fitting, and the pair of mounting portions 11 and 12 are fitted into both edge portions of the upper flange 1a of the structural member 1 made of, for example, I type steel. In this state, the upper plate portion 15 is located on the upper surface of the structural member 1 with a space. The lower end of the column 2 is inserted through the hole 16 of the upper plate 15, and the column 2 is received on the upper surface of the structural member 1. Further, the tightening bolt 19 is inserted through the bolt insertion holes 17 and 18 of the pair of legs 13 and 14 and the bolt insertion hole 23 formed in the column 2, and the nut 20 is screwed into the tightening bolt 23. And both are tightened.

With this mounting structure, the pair of mounting portions 11, 12 strongly clamp the flange 1a of the structural member 1 by the tightening force of the tightening bolt 19 and the nut 20, and the mounting portions 11, 12 are Since 12 is engaged with the flange 1a, a strong attachment state is achieved. Further, since the column 2 is prevented from being pulled out upward from the hole 16 by the tightening bolt 19, it is securely prevented from being pulled out, and at the same time, is supported by the tightening bolt 19 and the hole edge of the hole 16. It does not cause a large wobble.

FIG. 2 shows an example of a procedure for fitting the pair of mounting portions 11 and 12 into both edge portions of the flange 1 a of the structural member 1. That is, in this example, one of the mounting portions 11 is first fitted into the edge portion of one side of the flange 1a, and from that state, the invoking guide piece 22 of the other mounting portion 12 is indicated by the phantom line in the figure. The flange 1a is abutted against the other edge, and then the other mounting portion 12 is strongly pushed in the direction of the arrow X, and the elasticity of the legs 13, 14 is used to attach the mounting portion 12 to the other side of the flange 1a. It is designed to fit into the side edge. When this method is adopted, it is only necessary to provide the invoking guide piece 22 only on one of the mounting portions 12 (the other mounting portion 12 in the drawing). Although the guide pieces 21 and 22 are not essential, the presence of the guide pieces 21 and 22 facilitates the work of fitting the mounting portions 11 and 12 into the flange 1a. Further, even if an external force such as wind pressure acts upward, the mounting portion is less likely to be deformed, and the mounting portion is firmly held by the structural member.

In this embodiment, the upper flange 1a of the structural member 1 made of I-shaped steel is pinched by the pair of mounting portions 11 and 12, but this point is that the entire structural member 1 is clamped from both sides. You may be able to hold it. An example of that case is shown in FIG. 3 in the case where the structural member 1 is C-type steel. Further, since the work of tightening the tightening bolt 19 is performed higher than the upper surface of the structural member 1, it is safe, and the work can be completed in a short time because the tightening work only needs to be performed on one bolt. When the mounting device A is removed from the structural member 1, the tightening bolt 19 may be loosened to detach the mounting parts 11 and 12 from the flange 1a.

FIG. 4 shows a usage state of another embodiment. In the mounting device A of this embodiment, a screw hole 32 is formed in a U-shaped mounting portion 31, a pressing bolt 33 is screwed into the screw hole 32, and an upper plate portion 35 is bent at the upper end portion of the leg portion 34. The upper plate portion 35 is formed with a hole portion 36 through which the support column 2 is inserted, and the leg portion 34 is formed with a bolt insertion hole. In this mounting apparatus A as well, when the mounting portion 31 is mounted on the structural member 1, the upper plate portion 35 is positioned so as to be spaced apart from the upper surface of the structural member 1. The tightening bolts 33 may be plural in number. Other matters are the same as those of the mounting device A in FIG.

In this embodiment, the mounting portion 31 is fitted to the edge portion of the flange 1 a of the structural member 1 and the pressing bolt 33 is tightened to mount the mounting portion 31 to the structural member 1. Further, the column 2 is inserted into the hole 36, the lower end thereof is placed on the upper surface of the structural member 1, and the tightening bolt 19 is inserted into the bolt insertion hole of the leg 34 and the bolt insertion hole 23 of the column 2. The column 2 is fixed to the attachment device A by screwing and tightening the nut 20. When removing the attachment device A from the structural member 1, the pressing bolt 33 may be loosened to detach the attachment portion 31 from the flange 1a.

Also in this embodiment, since the work of tightening the tightening bolt 19 and the pressing bolt 33 is performed above the upper surface of the structural member 1, it is safe and the work can be easily performed.

In the two embodiments described above, the tightening bolt 19 and the nut 20 are examples of the retaining means for preventing the column 2 from coming out of the holes 16 and 36. The shape of the column 2 and the shapes of the holes 16 and 36 may be other than circular.
