Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slope stabilization method for slopes such as a slope such as a highway created by an open cut method or various facilities, or a steep slope having a possibility of collapse (for greening, etc.). The present invention relates to an inspection frame for forming a legal frame that regulates external dimensions when forming a legal frame beam of the in-situ construction method.
[0002]
[Prior art and its problems]
A conventional inspection frame for the formation of a legal frame that regulates the external dimensions for arranging reinforcing bars in a grid on the slope and spraying mortar or concrete on this reinforcing bar to form a grid-shaped frame beam on the slope As a technique, as shown in Japanese Patent Application Laid-Open No. Hei 8-74261, the first members arranged in parallel are connected via a second member, and a reinforcing member holding member is erected (laterally) on the left and right second members. ing.
[0003]
The rebar arranged on the slope is lifted and brought into contact with the upper rebar holding member, while binding the rebar to the rebar holding member via a wire.
[0004]
According to such a method, the rebar is tied to the rebar holding member via a wire, so that the work of holding the rebar takes a considerable amount of time, resulting in a significant increase in cost and a danger of binding the steep terrain. There were also problems.
[0005]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make it possible to extremely easily perform a work of supporting a reinforcing bar with respect to a measurement frame and to greatly improve work efficiency.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a reinforcing bar in a grid pattern on a slope, and mortar or concrete is sprayed on the reinforcing bar to form an outer dimension for forming a grid-shaped frame beam on the slope. The inspection frame for the formation of a legal frame that regulates the above, the inspection frame for the formation of the legal frame, an external member whose both ends face down along the external shape of the legal frame beam, at the top of this external member An inspection frame composed of a rebar holding member having a holding recessed portion for holding the rebar by dropping in the middle while attaching and suspending the upper end is adopted.
[0007]
In addition, a configuration is adopted in which at least two exterior members are attached to a connecting member that connects upper ends of the reinforcing bar holding members, and at least two exterior reinforcing members are vertically suspended from the top of the exterior member. Sometimes.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the accompanying drawings.
[0009]
In the first embodiment of the present invention, as shown in FIGS. 1 to 4, an external member 1 having both ends (grounding ends) facing downward along the external shape of a normal frame beam B to be formed on a side surface A. And a rebar holding member 3 having a holding recess 2 for holding the rebar C by dropping in the middle while fixing and attaching the upper end to the top of the exterior member 1 by, for example, spot welding or the like, and vertically hanging the rebar C in the middle. An inspection frame D for forming a legal frame is formed.
[0010]
The external appearance member 1 is bent in a substantially semi-arc shape along the outer peripheral surface of the substantially semi-arc shaped frame beam B in the illustrated case, but if the shape of the normal frame beam B, for example, in the case of a trapezoid, is bent in a trapezoidal shape, Good.
[0011]
In the illustrated example, the external member 1 is formed by bending a metal wire rod. However, for example, a metal strip may be used by bending.
[0012]
Further, as shown in the drawing, the holding recessed portion 2 has a U-shaped bend in the middle of the reinforcing bar holding member 3 and an opening formed by the U-shaped bend is positioned diagonally upward and the bottom is positioned diagonally downward. The escape of the dropped reinforcing bar C is prevented by vibration or other causes.
[0013]
In the illustrated case, the reinforcing rod holding member 3 is formed by bending a metal wire in the same manner as the appearance member 1, but is formed by bending a metal strip or punching out the holding recess 2 by pressing. And the like.
[0014]
In addition, although the recessed part 2 was arrange | positioned above and below one rebar holding member 3 as shown in FIG. 1, 2, it is not limited, As shown in FIG. In the middle of each of the members 3, in addition to the two reinforcing bars C being provided so as to be arranged vertically, as shown in FIG. A total of four reinforcing bars C may be arranged at the locations.
[0015]
Next, a method of using the inspection frame D will be described.
[0016]
First, after the reinforcing bar C is placed on the construction line of the sloping beam on the slope, both ends of the outer member 1 are grounded while the outer member 1 of the inspection frame D straddles the reinforcing bar C.
[0017]
Then, the lifted rebar C is dropped into the recess 2 of the rebar holding member 3 as shown in FIG.
[0018]
By repeating the above operation, the reinforcing bars C are dropped into the recessed portions 2 while the inspection frames D are arranged at predetermined intervals of the reinforcing bars C, and the reinforcing bars C are floated on the slope A.
[0019]
A wire mesh (not shown) may be laid on the slope A in advance.
[0020]
Thereafter, a mortar or concrete blasting material 5 is sprayed from the nozzle at the tip of the hose toward the reinforcing bar C by pump-up, and a grid-shaped normal frame beam B is constructed as shown in FIG.
[0021]
At this time, the standard of the width and height of the mortar or concrete spraying material 5 to be sprayed can be detected by the inspection frame D.
[0022]
Naturally, the inspection frame D is buried in the normal frame beam B.
[0023]
In the second embodiment of the present invention, as shown in FIGS. 7 to 9, at least two exterior members 1 constituting the inspection frame D of the first embodiment are arranged side by side.
[0024]
At least two side-by-side parallel appearance members 1 and 1 are fixed by spot welding to a connecting member 11 that connects the upper ends of the parallel reinforcing bar holding members 3 and 3 having the concave portions 2.
[0025]
In addition, in the case shown in FIG. 7, the auxiliary leg members 12 are provided on the side-by-side appearance members 1 and 1, but are not necessarily required as shown in FIG. 9.
[0026]
Naturally, the rebar holding members 3 can be provided side by side (as shown in FIG. 6) at both ends of the external appearance member 1, and are not limited to one location of the concave portion 2.
[0027]
The method of using the parallel inspection frame D of the exterior member 1 is the same as in the first embodiment, and a description thereof will be omitted.
[0028]
Then, the inspection frame D can be stably stood upright with respect to the slope by the parallel appearance member 1.
[0029]
As shown in FIGS. 2, 5, 6, 7 and 9, when the lower end of the reinforcing bar holding member 3 is aligned with a line connecting both ends of the external appearance member 1, the lower end of the reinforcing bar holding member 3 is attached to the slope A. Is grounded, so that deformation of the appearance member 1 due to the weight of the holding reinforcing bar C can be eliminated.
[0030]
【The invention's effect】
As described above, according to the inspection frame of the present invention, since the reinforcing steel is dropped into the recessed portion and the reinforcing steel is held by the reinforcing steel holding member, the reinforcing steel is attached to the reinforcing steel holding member via a wire (to be held). ) No work is required.
[0031]
For this reason, the work of holding the reinforcing bar with respect to the inspection frame can be performed extremely efficiently.
[0032]
In addition, the inspection frame set up by the juxtaposition of the exterior members can be stably stood up, and the workability can be remarkably improved.
