DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame for forming a legal frame used for greening of slopes such as roads and land for construction, and a legal frame construction method using this frame.

[0002]

2. Description of the Related Art When greening a slope, a mesh such as a wire mesh is laid on the slope, a reinforcing bar is arranged on the mesh, and concrete or mortar (hereinafter, referred to as "mortar") 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).

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.

[0004]

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.

[0005] Further, since it is necessary to separate the rebar from the slope by 5 cm or more, the rebar is floated on the slope by floating the net or using an anchor pin. 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.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and allows a grid-shaped method frame having a standard size to be easily formed without requiring skill, and furthermore, the positioning of a reinforcing bar at that time can be performed. It is an object of the present invention to provide a frame for forming a legal frame and a legal method for constructing the legal frame using the frame, in addition to being reliably and easily achieved.

[0007]

A shape that bends downward when viewed from the front in the direction over the legs of
Hold and lift the reinforcing bar to a predetermined height position in its bending position
Providing a rebar erection material where the rebar erection part to be held is formed
It is characterized in that Oh Ru.

[0008] Then, two rebar reinforcing parts of the horizontal wire are installed.
Alternatively, two reinforcing bar installation parts of the reinforcing bar installation material may be provided.

[0009] The present onset Ming, established in a grid pattern on the slopes of the frame body as described above, rebar erection of the reinforcing bar bridging member
Parts and rebar bridged the reinforcing bars erection of the horizontal lines material, then modulo frame construction method, characterized in that spraying concrete or mortar to embed these reinforcing bars to form a grid-like law frame To provide .

It is needless to say that the shape of the frame in a front view is determined by the shape of the horizontal wire. Then, although not the shape of the horizontal member is limited, extending for example as a horizontal member, a pair of legs, towards both sides of the corner portion of the intermediate portion having a shape you bent downward obliquely downward If it is made, the frame body becomes a substantially M shape that widens toward the end in front view,
It said leg, from both sides of the corner portion of the intermediate portion having a shape you bent downward and that is extended toward the vertically downward, the outer shape of the frame becomes a gate-shape in front view .

[0011]

SUMMARY OF] According to the above characteristic structure, set up a frame in a grid pattern on a slope at a predetermined pitch, and, for each horizontal line material constituting the frame, shape you bent downward in front view Reinforcing bars are erected on the reinforcing bar erected portion formed at the bending position provided in the intermediate portion having, and by spraying mortar or the like so as to bury them, a predetermined lattice-shaped frame is formed on the slope.

At this time, since the reinforcing steel erected on the reinforcing bar erection portion is formed by a horizontal wire or a reinforcing bar erection member whose bent portion is bent downward, the erection position can be determined by the own weight of the reinforcing bar, and Can be performed very easily.

Further, since the frame serves as a measure of the spray width and the spray height of the mortar or the like, the height and width of the frame are defined as quality control standards for obtaining a grid-like method frame having a required strength. 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.

As described above, when the frame is formed in a substantially M-shape that is widened in a front view, the frame itself has an excellent function in terms of stable installation on a slope, and furthermore, Needless to say, such a configuration is suitable for transporting the frames in an overlapping manner.
