Description of the Related Art When greening a slope, a mesh such as a wire mesh is laid on the slope, and reinforcing bars are arranged in a grid on the mesh, and mortar or concrete (hereinafter, referred to as "metal") is buried in the reinforcing bar. Mortar, etc.) to form a grid-like legal frame, and spray a vegetation material containing various seeds and fertilizers into the lattice of this legal frame, or vegetation loaded with the vegetation material described above. A method of arranging a bag and germinating and growing various seeds contained in the vegetation material in the framing frame while protecting the vegetation material from flowing out by the above-mentioned lattice-shaped method frame (for example, Japanese Patent Publication No. 58-20338). See).

れていることは周知の通りである。By the way, according to the current civil engineering standards, the thickness of a mortar or the like that covers the above-mentioned reinforcing steel (this is referred to as “covering thickness”) must be 5 cm or more from any surface of the reinforcing steel. It is well known that it is required as a quality control standard to obtain.

バラツキが生じることを避けることができなかった。However, since the spraying of mortar and the like is performed at an unstable place on the slope,
The thickness and width of the mortar sprayed on the rebar are likely to be non-uniform, requiring considerable skill to form a grid-shaped frame with predetermined dimensions, and causing variations in the dimensions and strength of the grid-shaped frame. I couldn't avoid it.

When performing spraying work or other work on mortar, etc., the height position of the reinforcing bar is inevitably caused by stepping on the mesh, or by unexpected bending of the reinforcing bar or knocking down the anchor pin. Can not be determined as prescribed, and furthermore, it is not possible to check from the outside whether or not a layer of mortar or the like is formed with a predetermined thickness around the reinforcing bar, so that a lattice-shaped method frame that does not meet the standard Was occasionally formed.

A frame that serves as a measure of the spray width and spray height of mortar or concrete, and has a shape that bends downward when viewed from the front, and raises a reinforcing bar to a predetermined height position at the bending position. Let me hold
And an intermediate portion where a reinforcing bar erection portion for determining the erection position of the reinforcing bar by its own weight is formed, and a plurality of horizontal wires having a pair of legs extending downward from corner portions on both sides of the intermediate portion. It is characterized in that it comprises vertical wires arranged in a plurality of upper and lower stages so as to connect the legs of the horizontal wire to each other, and the corner portion is arranged at a position higher than the reinforcing bar erection portion.

It may be a concave polygon having one convex part and two concave parts that project upward at the middle part and serve as a measure of the spraying height of mortar or the like.

を提供する。The present invention also relates to a method for constructing a frame using the above-mentioned frame, wherein the frame, which is a measure of the spray width and spray height of mortar or concrete, is installed in a grid on the slope. A reinforcing bar is erected on the reinforcing bar erection portion of the horizontal wire, and then mortar or concrete is sprayed so as to embed the frame body including the reinforcing bar to form a grid-shaped legal frame. I will provide a.

ば、枠体の外形は正面視で門型の形状となる。It is needless to say that the shape of the frame in a front view is determined by the shape of the horizontal wire. And although the shape of the horizontal wire is not limited, for example, as the horizontal wire, a pair of legs is extended obliquely downward from both side corners of the intermediate portion having a shape bent downward. If it is assumed, the frame body becomes a substantially M-shape diverging in a front view,
If the leg extends vertically downward from both corners of the intermediate portion having a shape that is bent downward, the outer shape of the frame has a portal shape in a front view.

とで、法面上に所定の格子状法枠が形成される。According to the above-mentioned characteristic structure, the frame is installed in a grid pattern on the slope at a predetermined pitch, and each of the horizontal wires constituting the frame has a shape bent downward in a front view. Reinforcing bars are erected on the reinforcing bar erection portion formed at the bending position provided in the intermediate portion, and a mortar or the like is sprayed so as to embed them, whereby a predetermined grid-like method frame is formed on the slope.

If it is set in advance based on the above, the mortar or the like, including the reinforcing bar, is simply sprayed so as to embed the vertical and horizontal frames, and the grid has a predetermined size and strength with the reinforcing bar buried with the predetermined thickness. The legal framework can be easily formed by anyone without skill.

The third locking portion 13b is locked and connected to the vertical wire 12 welded to the other leg 11b of the horizontal wire 11 from above. At this time, at the bending position at the center in the width direction of the reinforcing bar installation material 13, the reinforcing bar 3 is connected to the reinforcing bar installation portion 11 c of the horizontal wire 11 and the slope A.
Is mounted so as to be located in the middle of the above, whereby the installation position of the reinforcing bar 3 can be easily held at a predetermined position by its own weight.

If it is set in advance based on the above, a grid having a predetermined size and strength in a state in which the reinforcing bar is buried with a covering thickness of a predetermined size by simply spraying mortar or the like so as to embed the vertical and horizontal frames including the reinforcing bar. The shape frame can be easily formed by anyone without skill.

きる。Moreover, since the frame body can be used as a guide for spraying mortar or the like, a grid-like method frame having the strength as specified dimensions can be formed. That is, if the height and width dimensions of the frame are set in advance based on quality control standards for obtaining a grid-like frame with the required strength, it is possible to simply embed the vertical and horizontal frames, including the reinforcing bars. Just by spraying mortar, etc., a grid-shaped method frame with a predetermined size and strength in a state where the rebar is buried with a cover thickness of a predetermined size,
It can be easily formed by anyone without skill.
