Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold for driving a sloped anchor bolt suitable for driving an anchor bolt on a sloped surface.

[0002]

2. Description of the Related Art As a method of stabilizing and strengthening slopes, steel anchor bolts having a length of about 1.5 to 2.5 m are placed at a predetermined interval in the vertical and horizontal directions on the slopes substantially perpendicularly to the slope. However, at this time, conventionally, it has been common to drive anchor bolts using a scaffold 55 as shown in FIG. 10, for example.

That is, in this scaffold 55, a round steel pipe 56 is framed along a slope of a slope 57 via a clamp or the like (not shown), and a plurality of scaffold plates 59 are provided between horizontal beams 58 located at a predetermined height. Is installed to form the working floor 60, and the anchor bolt 61 is driven by fixing the anchor bolt 61 driving machine 62 at a predetermined position on the working floor 60.

[0004]

SUMMARY OF THE INVENTION In the above conventional technique,
Since the placing machine 62 is simply placed and fixed on the work floor 60 of the scaffold 55, it is difficult to finely adjust the placing height,
Moreover, it is more difficult to match the driving angles at the same time even if the driving heights are adjusted, and it takes a great deal of time to accurately set the anchor bolt 61 to the predetermined height and the predetermined angle.

Further, in the conventional scaffold 55, the setting work is performed from the work floor 60 at the lower stage, but the work floor 60 at the upper stage is performed.
When moving the placing machine 62 to, it is necessary to lift the work with a raker vehicle or the like, and further, when the predetermined placing work in the longitudinal direction of the slope 57 is completed and the next span is constructed, The scaffold 55 itself had to be disassembled and reassembled, which caused an increase in construction period and construction cost. Further, in the case of the slope 55 whose inclination angle changes sequentially in the longitudinal direction, it requires a great deal of skill and time to assemble the scaffold 55.

In view of the above points, the present invention provides a scaffold for driving a sloped anchor bolt, which can drive an anchor bolt at a predetermined height and angle by a simple operation and can minimize the construction period and construction cost. The purpose is to provide.

Always adjust the angle of 8 and always use the anchor bolt 7 for slope 2
It can be placed almost perpendicular to the. At this time, in order to prevent the operation console 21 and the angle adjusting mechanism 40 from interfering with each other, the retractable cylinders are respectively provided at the front center of the substrate 31.
43 and the relief hole 44 and the relief recess for the first bracket 26
45 is formed (see FIG. 7).

In FIGS. 8 and 9, an upper carriage 46 is provided with a pair of support arms 47 extending from the slope 2 side of the upper part of the elevating rail 5. A support shaft 48 is erected between the tips of both support arms 47.
Traveling rollers 49 that are rotatable around the support shaft 48 are attached to both ends of the roller. The traveling roller 49 is substantially parallel to the longitudinal direction of the slope 2 on the ground 50 above the slope 2.
Therefore, the rail 51 is fitted to the rail 51 laid parallel to the rail 10 for the traveling carriage 4. Therefore, the lifting rail
The lower end 5 is supported by the traveling carriage 4 at the lower end and the upper carriage 46 at the upper part, and keeps a constant distance along the rails 10,51 on the upper base plates 3,50 and with respect to the slope 2. However, it is possible to run in the longitudinal direction of slope 2.

The supporting arm 47 is adjustable in its withdrawal length so that the lifting rail 5 can be supported in a proper position even if the vertical length of the slope 2 changes. The mounting position in the vertical direction with respect to 5 is changeable. Further, in FIG. 1, 52 and 53 are anchors and ropes, respectively, which are provided after the elevating rail 5 is set at a predetermined position in the longitudinal direction of the slope 2 and the elevating rail 5 falls due to the reaction force of the anchor bolt 7 driving. Is to prevent.

When performing the placing work using the scaffolding 1 for placing the sloped anchor bolts having the above structure, first, the rails 10 and 51 are laid on the upper and lower grounds 3 and 50, and then each rail 10 is laid. ,Five
Set traveling carriage 4 and upper carriage 46 to 1 respectively,
The lifting rail 5 is attached to the slope 2 at substantially the same inclination as the slope 2 by adjusting the support arm 47 of the upper carriage 46 to move back and forth. next,
After setting the elevating rail 5 at a predetermined position in the longitudinal direction 2 of the slope 2 through traveling and traveling of the upper carriage 4,46, the anchor 52
And prevent the inversion by the rope 53 and fix the lifting rail 5 in that position. Then, after the horizontal state of the operation console 21 is obtained by the horizontal holding mechanism 33, the driving angle of the driving machine 8 is set to be substantially perpendicular to the slope 2 by the angle adjusting mechanism 40. After that, by moving the work carriage 6 up and down along the lifting rails 5, the anchor bolts 7 can be continuously driven at an arbitrary height position on the slope 2 and at an arbitrary pitch.

Further, as shown by the phantom line in FIG. 1, when the inclination angle of the slope 2 changes, the lifting rail 5 is rotated with respect to the traveling carriage 4 and a new set is made so as to follow the inclination angle. The horizontal holding mechanism 33 and the angle adjusting mechanism 40 may adjust the angles of the operation console 21 and the setting machine 8 with respect to the elevating rail 5 accordingly. Therefore, the scaffolding for placing 1 according to the present embodiment can be applied to one scaffolding 1 even for the slope 2 in which the inclination angle changes sequentially along the longitudinal direction.

The present invention is not limited to the above embodiment. That is, for example, the traveling carriage 4 is not limited to traveling on the rails 10, but may be one having a self-propelled means such as a crawler. Further, instead of providing the upper carriage 46, a roller may be provided at the end of the support jack 19 on the slope 2 ground contact side. Further, it goes without saying that the configurations of the horizontal holding mechanism 33 and the angle adjusting mechanism 40 are not limited to those in the above embodiment.
