Abstract

PURPOSE:To facilitate a concreting work and reduce a construction cost to a value as low as possible when an anchor bolt 7 is driven in a slope 2. CONSTITUTION:A working truck 6 at the interior of which a driving machine 8 for an anchor bolt 7 is mounted is installed on an elevating rail 5 installed on a slope 2 along the vertical direction of the slope 2. An angle regulating mechanism 40 to regulate the driving direction of the anchor bolt 7 based on the slope 2 is arranged between the working truck 6 and the driving machine 8. The lower end part of the elevating rail 5 is locked rotatably in the inclination direction of the slope 2 to the running truck 4 runnable longitudinally of the slope 2 on a ground 3 under the slope 2. This constitution simply and reliably drives the anchor bolt 7 in a given height position on the slope 2 and at a given angle. When the slope 2 having a new span is constructed, the running truck 4 is run longitudinally of the slope 2, and coping with a situation is practicable without re-erecting a scaffolding 1 itself by resetting the elevating rail 5.

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope anchor bolt driving scaffold suitable for driving anchor bolts onto a slope.

0002

[Prior Art] As a method for stably strengthening slopes, steel anchor bolts approximately 1.5 to 2.5 m in length are driven approximately perpendicular to the slope at predetermined intervals in the length and width of the slope. However, in this case, it has conventionally been common to use a scaffold 55 as shown in FIG. 10, for example, to drive the anchor bolt.

That is, this scaffolding 55 is constructed by framing round steel pipes 56 via clamps (not shown) so as to follow the slope of a slope 57, and a plurality of scaffolding boards 59 are placed between cross beams 58 located at a predetermined height. An anchor bolt 61 is driven by a driving machine 62 for anchor bolts 61 fixed at a predetermined position on the work floor 60.

0004

[Problem to be solved by the invention] In the above conventional technology,
Since the pouring machine 62 is simply placed and fixed on the work floor 60 of the scaffolding 55, it is difficult to finely adjust the pouring height, and even if the pouring height is adjusted, the pouring angle cannot be adjusted. It is more difficult to align the anchor bolts 61 at the same time, and it takes a lot of effort to accurately set the anchor bolts 61 at a predetermined height and angle.

[0005] Furthermore, with the conventional scaffolding 55, the pouring work is performed from the lower working floor 60, but when moving the pouring machine 62 to the upper working floor 60, lifting work using a raker or the like is necessary. Moreover, when the specified pouring work in the longitudinal direction of the slope 57 is completed and the construction of the next span is started, the scaffolding 55 itself must be dismantled and reassembled, which reduces the construction period and time. This caused an increase in construction costs. Furthermore, in the case of a slope 55 whose inclination angle changes successively in the longitudinal direction, it requires great skill and effort to assemble the scaffold 55.

[0006] In view of these points, the present invention provides a scaffold for driving anchor bolts on slopes, which allows anchor bolts to be driven at a predetermined height and angle with simple work, and which can minimize the construction period and construction cost. The purpose is to provide.

[0007]

[Means for solving the problem] In order to achieve the above purpose,
The present invention has taken the following technical measures. That is, in the invention according to claim 1, a work cart 6 equipped with a driving machine 8 for anchor bolts 7 is lifted and lowered on a lifting rail 5 attached to the slope 2 along the vertical direction of the slope 2. It is characterized in that it is freely provided and is equipped with an angle adjustment mechanism 40 between the work cart 6 and the driving machine 8 for adjusting the driving direction of the anchor bolt 7 with respect to the slope 2.

[0008] Further, in the invention according to claim 2, the lower end portion of the lifting rail 5 is arranged so that the lower end portion of the lifting rail 5
It is characterized in that it is rotatably supported in the direction of inclination of the slope 2 by a traveling carriage 4 that can travel in the longitudinal direction.

[0009]

[Operation] The angle adjustment mechanism 40 sets the driving direction of the anchor bolt 7 on the slope 2 of the driving machine 8 to a predetermined direction (for example, perpendicular to the slope 2). The work trolley 6 is equipped with a pouring machine 8 that can adjust the pouring direction using the angle adjustment mechanism 40, and is equipped with the pouring machine 8 and a worker (not shown) inside to move the concrete in the vertical direction of the slope 2. The driving machine 8 is moved up and down along the attached lifting rail 5 to transport the driving machine 8 to a predetermined driving position.

The elevating rail 5 is pivotally supported by the traveling carriage 4, and even if the inclination angle of the slope 2 changes, it rotates according to the inclination angle and is attached to the slope 2. The traveling trolley 4 is
It travels along the longitudinal direction of the slope 2 above the ground 3 below the slope 2, and the lifting rail 5 is placed at a predetermined position in the longitudinal direction of the slope 2.

The lower end of each frame structure 13 is pivotally connected to the traveling carriage 4 via support brackets 17 protruding from the carriage 4 at positions sandwiching the electric winch 11 from the front and back. The elevating rail 5 is configured to be rotatable in the direction of inclination of the slope 2 with respect to the traveling trolley 4 (see imaginary line in FIG. 1). In addition, 18
is an inclined jack, which is provided in a bulge-like manner between the upper surface of the traveling truck 4 and the lower end of each frame structure 13. Also,
Reference numeral 19 denotes a support jack, which protrudes from each frame structure 13 toward the slope 2 side, and connects the lifting rail 5 to the slope 2 side.
This is to hold it approximately parallel to the slope 2 according to the slope of the slope.

As shown in FIGS. 4 and 5, the work cart 6
includes a slider 20 slidably interposed between each frame structure 13, and an operation table 21 supported by the slider 20. A pair of grooved rollers 22 are pivotally supported in the width direction on both the upper and lower left and right sides of the slider 20, and as shown in FIG. It is fitted between 14. A wire 23 extending from the electric winch 11
The vertical rail 5 passes through the slope 2 side of the vertical rail 5.
It reaches this slider 20 via a pulley 24 provided at the top, and is connected to a hanging metal fitting 25 projecting from the upper end of the slider 20. Also, the upper surface of the slider 20 in the thickness direction
A first bracket 26, a second bracket 27, a third bracket 28, and a fourth bracket 29 are respectively protruded from the upper side in the lifting direction (the surface on the opposite side of the slope 2).

The operation table 21 includes a base plate 31 whose upper surface is treated with a non-slip 30, and a handrail 32 projecting upward from the side of the base plate 31. In this embodiment, the operation table 21 and A horizontal holding mechanism 33 for the operating table 21 is configured between the sliders 20. That is, the substrate 31 has its lower front side
Pivot bracket 3 installed on the bottom side of Figure 7, right side of Figure 4
The cylinder bracket 35 is pivotally supported by the second bracket 27 of the slider 20 via the cylinder bracket 35 and the fourth bracket 29 of the slider 20, which is provided on the rear side of the lower surface of the board 31.

The driving machine 8 includes a driving motor 37 that applies rotational force to the anchor bolt 7, and a driving motor 37 that rotates the motor 37 on the slope 2.
It consists of a slide guide 38 that slides to the side, and a support stand 39 that supports this slide guide 38 from below, and is mounted within the operation stand 21. In this example,
Separately from the horizontal holding mechanism 33 of the operating table 21, an angle adjustment mechanism 40 is provided between the driving machine 8 and the slider 20 of the work cart 6 to adjust the driving direction of the anchor bolt 7 relative to the slope 2 of the driving machine 8. is equipped with. That is, the support stand 39 is pivotally supported by the first bracket 26 of the slider 20 via a pivot bracket 41 provided on the front part of the lower surface thereof, and is further supported by a cylinder bracket 42 provided on the rear side of the lower face of the support stand 39. By interposing the retractable cylinder 43 between the third bracket 28 of the slider 20 and the third bracket 28 of the slider 20,
Even if the inclination angle of the slope 2 changes as shown in the imaginary line in FIG. 1, the anchor bolt 7 can always be driven approximately perpendicular to the slope 2 by adjusting only the angle of the driving machine 8. It looks like this. At this time, in order to prevent the operating table 21 and the angle adjustment mechanism 40 from interfering with each other, an escape hole 44 and an escape recess 45 are formed at the center of the front part of the board 31 for the evacuation cylinder 43 and the first bracket 26, respectively. (See Figure 7).

In FIGS. 8 and 9, reference numeral 46 denotes an upper carriage, which is provided with a pair of support arms 47 extending from the slope 2 side of the upper part of the lifting rail 5. Both support arms 4
A support shaft 48 is installed between the ends of the support shaft 7, and running rollers 49 rotatable around the support shaft 48 are attached to both ends of the support shaft 48. The running roller 49 runs on the slope 2 on the ground 50 above the slope 2.
substantially parallel to the longitudinal direction (therefore, the traveling carriage 4
It is fitted to a rail 51 laid parallel to the rail 10 for use. Therefore, the lifting rail 5 is supported by the traveling truck 4 at the lower end and by the upper truck 46 at the upper end, and is supported by the rail 10 on the upper and lower ground 3, 50.
51 and in the longitudinal direction of the slope 2 while maintaining a constant distance from the slope 2 .

Furthermore, in order to be able to support the lifting rail 5 at a proper position even if the vertical length of the slope 2 changes, the support arm 4 is
7 is adjustable in its protruding and retracting length, and its mounting position relative to the elevating rail 5 in the elevating direction can be changed. In addition, in FIG. 1, 52 and 53 are anchors and ropes, respectively, which are installed after the lifting rail 5 is set at a predetermined position in the longitudinal direction of the slope 2, and the lifting rail 5 falls due to the reaction force of the anchor bolt 7. This is to prevent

When performing driving work using the slope anchor bolt driving scaffold 1 having the above configuration, first, after laying the rails 10, 51 on the upper and lower ground 3, 50,
The traveling truck 4 and the upper truck 46 are set on each rail 10, 51, respectively, and the support arm 47 of the upper truck 46 is set on each rail 10, 51.
The lifting rail 5 is attached to the slope 2 at approximately the same slope as the slope 2 by adjusting the opening and retracting of the rail. Next, after the lifting rail 5 is set at a predetermined position in the longitudinal direction of the slope 2 through traveling and the traveling of the upper carts 4 and 46, the lifting rail 5 is prevented from being reversed by the anchors 52 and ropes 53, and the lifting rail 5 is held at that position. Fix it. After the operating table 21 is brought into a horizontal state by the horizontal holding mechanism 33, the angle adjusting mechanism 40 sets the driving angle of the driving machine 8 to be approximately perpendicular to the slope 2. Thereafter, by raising and lowering the work cart 6 along the lifting rail 5, the anchor bolts 7 can be continuously driven at any height position on the slope 2 at any desired pitch.

Furthermore, as shown in the imaginary line in FIG. 1, when the slope angle of the slope 2 changes, the lifting rail 5 is rotated relative to the traveling trolley 4 and newly set to follow the slope angle. The horizontal holding mechanism 33
The angle of the operating table 21 and the driving machine 8 with respect to the lifting rail 5 can also be readjusted using the angle adjustment mechanism 40. Therefore, the pouring scaffold 1 according to this embodiment can be applied to a slope 2 whose inclination angle changes successively along the longitudinal direction.

It should be noted that the present invention is not limited to the above embodiments. That is, for example, the traveling trolley 4 is not limited to one that runs on the rails 10, but may be one that has self-propelled means such as a crawler. Further, instead of providing the upper truck 46, a roller may be provided at the end of the support jack 19 on the grounding side of the slope 2. Furthermore, it goes without saying that the configurations of the horizontal holding mechanism 33 and the angle adjustment mechanism 40 are not limited to those of the above embodiment.

Effects of the Invention According to the invention described in claim 1, the casting machine 8
is mounted on a work cart 6 that can be raised and lowered along the lifting rail 5, and is provided with an angle adjustment mechanism 40 between the work cart 6 and the pouring machine 8, so that it can be placed at any predetermined height position on the slope 2. In addition, the anchor bolt 7 can be driven at a predetermined angle more easily and reliably than before, making the work easier and safer.

Further, according to the invention as set forth in claim 2, the lifting rail 5 is pivotally supported by the traveling carriage 4 and can be set in accordance with the inclination angle of the slope 2 .
Since it can run in the longitudinal direction, there is no need to reassemble the scaffolding 1 itself from the beginning even when driving anchor bolts 7 in a new span, and it can be used when the inclination angle of the slope 2 changes in the longitudinal direction. However, it can be handled with just one scaffolding 1, which in turn can contribute to a significant reduction in construction period and construction costs.
