DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the construction of slope protection works such as slopes facing highways and various facilities constructed by the open-cut method or steep slopes that may collapse. The present invention relates to a reinforcing bar support used.

[0002]

2. Description of the Related Art Conventionally, in order to arrange a main reinforcing bar at a predetermined height with respect to a ground slope, as shown in Japanese Patent Application Laid-Open No. 3-81419, a pair of anchor bars is provided on the ground slope. After that, the horizontal rod of the lower stirrup is fixed to the anchored bar through the wire.

Next, the main bars dropped into the lower stirrup are arranged on the horizontal rod of the lower stirrup.

The upper main bar is dropped into the lower stirrup, and then the vertical bar of the upper stirrup is fixed to both vertical bars of the lower stirrup by wire. The upper main bar is arranged via a wire.

[0005] Further, when reinforcing bars in the vertical and horizontal directions are arranged at a predetermined height with respect to the ground, an anchor reinforcing bar is driven into the slope of the ground, and a wire is passed through the driven anchor. Stop the intersection of the rebar in the vertical and horizontal directions.

[0006]

When the above-mentioned prior art is adopted, the lower stirrup for receiving the main bar is anchored to the anchor reinforcing bar through a wire, and the intersection of the reinforcing bar is stopped to the anchor reinforcing bar through the wire. However, there is a problem that it takes a lot of trouble.

In particular, since the lower stirrup and the reinforcing bar must be arranged at a certain height with respect to the ground slope, the fixing position of the stirrup and the reinforcing bar is determined using a gauge or the like.
Then, since the stirrup or the reinforcing bar is fixed to the anchor reinforcing bar by using a wire, the work efficiency is remarkably reduced and the construction cost is increased.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a slope reinforcing bar support in which the arrangement of the main reinforcing bars and the reinforcing bars is facilitated and the heights of the main reinforcing bars and the reinforcing bars relative to the ground slope are set to the set dimensions. I do.

[0009]

To solve the above problems BRIEF SUMMARY OF THE INVENTION This invention includes a driving rod, and a stop portion implantation provided in the lower outer periphery of the rod, located above the stop portion above A rebar support having a sloped surface is provided, which protrudes from the outer peripheral surface of the bar in two directions with a step at an angle of 90 degrees in a plane and has a horizontal receiving portion having an upwardly engaging portion at the protruding end. .

[0010] Further, a driving rod and a lower part of the lower part of the rod are provided.
The driving stop provided on the circumference and above this stop
At an angle of 180 degrees from the outer peripheral surface of the bar
Projecting in two directions with an upward engagement
And a two-stage receiving part at the same position
Use rebar supports .

[0011]

With the above construction, the bar is driven while hitting at predetermined intervals on the reinforcing bars on the ground slope.

When the stop reaches the slope, the driving of the bar is stopped, and the height from the slope to the receiving portion is set to the set height.

A reinforcing bar (main bar) to be arranged is received by a receiving portion.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a driving stop portion 2 is provided on the outer periphery of the lower portion of the driving rod 1.

For the above-mentioned bar 1, a reinforcing bar cut to a predetermined size is used, and the lower end is sharpened as shown in the figure.
Resistance at the time of driving can be reduced.

In the case of the drawing, the stop portion 2 has a metal annular plate 3 fitted on the outside of the bar 1 and fixes the annular plate 3 to the bar 1 by welding or the like, and the hammer uses a hammer. The bar 1 was driven from the slope to the ground while hitting, and the further driving was stopped when the annular plate 3 came into contact with the slope. Alternatively, a horizontal protruding rod (not shown) may be used as the stop portion.

The outer peripheral surface of the bar 1 is provided with a receiving portion 5 which protrudes horizontally from an upper position with respect to the stop portion 2 and has an upwardly engaging portion 4 at the end in the protruding direction.

As shown in FIG. 1, the receiving portion 5 projects in two directions at an angle of 90 degrees on a plane, and is provided with a step so as to receive intersecting reinforcing bars.

Then, as shown in FIG. 2, the driving rod 1 is driven into the intersection of the reinforcing bar B in the longitudinal direction and the reinforcing bar B in the horizontal direction. The intersecting portions of the reinforcing bars B arranged in the vertical and horizontal directions can be dropped into each of the receiving portions 5 having steps so that they can be received. At this time,
In order to prevent the reinforcing bar B from falling off the receiving portion 5 due to the lifting, it may be stopped by using a thin wire.

As shown in FIG. 2 , for example, as shown in FIG. 2 , a side plate 21 such as a wire mesh disposed on both sides of the reinforcing bar B has a hook portion 23 of a hook rod 22 rotatably attached to an appropriate position on the side plate 21. What is necessary is just to engage with the reinforcing bar B and attach it.

The receiving portion 5 with the engaging portion 4 is formed by bending a metal piece into a side surface L shape, and the end of the metal piece is fixed to the bar 1 by welding.

Further , as shown in FIG.
It is projected in two directions at an angle of 180 degrees,
It is provided in two positions at the position.

Then, as shown in FIG. 4 , after the bar 1 is driven into the slope A, the lower main bar B 'and the upper main bar B' which are arranged by the lower and upper receiving portions 5 are supported. Then, the lower stirrup C inserted below the lower receiving portion 5 is raised and raised, and the lower stirrup C is
The lower stirrup C is lifted so that the corners of the lower stirrup C are circumscribed, and the lower stirrup C is stopped through the wire D to the lower main streaks B ′.
And the upper stirrup C
And the upper stirrup C is stopped by the wire D at the upper main bar B ′.

The side plate 21 is locked to the main bar B 'via the hook of the hook rod 22.

[0026]

As described above, the reinforcing steel support for a slope according to the present invention is configured as described above, so that the stop position of the driving rod material is fixed by the stop portion, and Height becomes constant.

[0027] Co this reason, you are possible to height relative slope of the rebar arrangement muscle by受架the受架unit is equalized
And project in two directions with a step at an angle of 90 degrees on a plane
The support section connects the vertical and horizontal reinforcing bars with one support.
It can be mounted with a holding tool.

Further, the upper main reinforcement and the upper main reinforcement are provided by two upper and lower receiving parts.
And the lower main bar can be supported by one support
And arrange the main rebar in a state of rising to the slope.
So that the lower stirrup can be inserted and assembled
Work becomes easier.
