Description

[0001]
BACKGROUND OF THE INVENTION
This invention is a slope stabilization work (such as for greening) on slopes such as highways and slopes facing various facilities created by an open cut method or steep slopes that may collapse. The present invention relates to a measurement frame for forming a frame that regulates the external dimensions when forming a frame frame for the on-site method.
[0002]
[Prior art and problems]
Conventional measurement frame for forming a frame that regulates the external dimensions to form a grid-like frame beam on the slope by laying reinforcing bars in a grid on the slope and spraying mortar or concrete on the reinforcement As a technique, as shown in Japanese Patent Application Laid-Open No. 8-74261, the first members arranged in parallel are connected via the second member, and the reinforcing bar holding members are installed (horizontally mounted) on the left and right second members. ing.
[0003]
The reinforcing bar arranged on the slope is bound to the reinforcing bar holding member and the wire while being lifted and brought into contact with the upper reinforcing bar holding member.
[0004]
According to such a method, since the reinforcing bars are bound to the reinforcing bar holding member via the wire, the holding work of the reinforcing bars is remarkably troublesome and the cost is greatly increased, and the binding work of steep slopes is dangerous. There was also a problem.
[0005]
SUMMARY OF THE INVENTION Accordingly, the present invention is to enable a rebar support operation with respect to a measurement frame to be extremely simple and to greatly improve work efficiency.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides an external dimension for arranging a reinforcing bar in a grid shape on a slope and spraying mortar or concrete on the reinforcing bar to form a grid-like frame frame on the slope. An inspection frame for forming a legal frame that regulates the above-mentioned measurement frame for the above-mentioned legal frame, and an outer appearance member whose both ends are directed downward along the outer shape of the normal frame beam, and a top of the outer appearance member. An inspection frame is used which is vertically installed with an upper end, and a reinforcing bar holding member having a U-shaped holding recessed portion in which two upper and lower openings that hold the reinforcing bar by dropping in the middle are inclined upward .
[0007]
The front Symbol rebar holding member, also possible to adopt a configuration in which two vertically from the top of the exterior member.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments 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, the appearance member 1 whose both ends (grounding ends) are directed downward along the appearance shape of the frame frame beam B to be formed on the slope A. And a reinforcing bar holding member 3 having a holding recess 2 for holding the reinforcing bar C by dropping and fixing the upper end to the top of the external member 1 by, for example, spot welding. An inspection frame D for forming a normal frame is formed.
[0010]
In the illustrated case, the outer appearance member 1 is bent in a substantially semi-arc shape along the outer peripheral surface of the substantially half-arc shaped frame beam B. Good.
[0011]
In the illustrated example, the outer appearance member 1 is formed by bending a metal wire. However, for example, a metal strip may be bent and used.
[0012]
In addition, as shown in the drawing, the holding recessed portion 2 is bent in the middle of the reinforcing bar holding member 3 in a U-shape, and the opening due to the U-shaped bending is located obliquely upward and the bottom is located obliquely downward. The escape is prevented by the vibration of the dropped rebar C and other causes.
[0013]
Further, in the illustrated case, the reinforcing bar holding member 3 is also used by bending a metal wire material in the same manner as the appearance member 1, but a metal band plate is bent, or the holding recessed portion 2 is punched by a press. It may be a plate material.
[0014]
In addition, although the recessed part 2 was arrange | positioned at the upper and lower sides of the one reinforcing bar holding member 3 as shown in FIGS. 1 and 2, it is not limited, and as shown in FIG. In addition to providing the two reinforcing bars C so as to be arranged vertically in the middle of each of the members 3, as shown in FIG. A total of four reinforcing bars C may be arranged at a location.
[0015]
Next, a method for using the inspection frame D will be described.
[0016]
First, the reinforcing bar C is placed on the construction line of the normal frame beam on the slope, and then both ends of the external member 1 are grounded while the external member 1 of the inspection frame D straddles the reinforcing bar C.
[0017]
Then, the lifted reinforcing bar C is dropped into the recessed portion 2 of the reinforcing bar holding member 3 as shown in FIG.
[0018]
By repeating the above operation, the reinforcing bars C are dropped into the respective 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 with respect to the slope A.
[0019]
In addition, a wire mesh (not shown) may be laid on the slope A in advance.
[0020]
Thereafter, a mortar or concrete spray material 5 is blown from the tip nozzle of the hose toward the reinforcing bar C by pumping up, thereby constructing a grid-like frame frame B as shown in FIG.
[0021]
In that case, the standard of the width and height of the sprayed material 5 of the mortar or concrete sprayed can be detected by the measurement frame D.
[0022]
Naturally, the inspection frame D is embedded in the normal frame beam B.
[0023]
As shown in FIGS. 7 to 9, at least two external members 1 constituting the inspection frame D of the first embodiment are arranged side by side.
[0024]
At least two parallel appearance members 1 and 1 arranged in parallel are fixed to a connecting member 11 that connects the upper ends of parallel reinforcing bar holding members 3 and 3 having recessed portions 2 by spot welding.
[0025]
In the case shown in FIG. 7, the auxiliary leg members 12 are provided on the parallel appearance members 1, 1, but are not necessarily required as shown in FIG. 9.
[0026]
Naturally, the reinforcing bar holding member 3 can be arranged in parallel at both ends of the appearance member 1 (as shown in FIG. 6), and is not limited to one place of the recessed portion 2.
[0027]
The method of using the parallel inspection frame D of the external 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 erected with respect to the slope by the parallel appearance member 1.
[0029]
2, 5, 6, 7, and 9, when the lower end of the reinforcing bar holding member 3 is aligned with the line connecting both ends of the appearance member 1, the lower end of the reinforcing bar holding member 3 is set to the slope A. Can be grounded, and the deformation of the appearance member 1 due to the weight of the holding rebar C can be eliminated.
[0030]
【The invention's effect】
As described above, according to the inspection frame of the present invention, the reinforcing bar is dropped into the recessed portion and the reinforcing bar holding member is held by the reinforcing bar holding member, so that the reinforcing bar is attached to the reinforcing bar holding member via the wire. ) No need for work.
[0031]
For this reason, the rebar holding work with respect to the measurement frame can be performed very efficiently.
