Description

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 method of constructing a legal frame using the frame.

[0002]

2. 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 concrete or mortar (hereinafter Mortar, etc.) is sprayed to form a lattice-shaped legal frame, and the vegetation material mixed with various seeds and fertilizers is sprayed into the lattice of this legal frame, or the above-mentioned vegetation material is loaded. A method of sprouting and cultivating various seeds contained in the vegetation material within the legal frame by arranging a bag and protecting the vegetation material from running away by the above-mentioned lattice-shaped legal frame (for example, Japanese Patent Publication No. 58-20338). (See) is being taken.

By the way, according to the current civil engineering standards, the thickness of the mortar or the like covering the above-mentioned reinforcing bar (which is called the covering thickness) is 5 cm or more from any surface of the reinforcing bar. As is well known, it is obligatory as a quality control standard for obtaining.

[0004]

However, since spraying of mortar or the like is performed in an unstable place on the slope,
The thickness and width of the mortar sprayed on the reinforcing bars are likely to be non-uniform, and it requires considerable skill to form a grid-like method frame of a predetermined size, and the size and strength of the grid-like method frame may vary. I couldn't avoid it.

Further, since it is necessary to separate the reinforcing bar from the slope by 5 cm or more, the above-mentioned reinforcing bar is floated on the slope by floating the net or by using an anchor pin. When performing spraying work such as mortar, or other work, the height of the reinforcing bar should be adjusted because the mesh body should be stepped on, or by accidentally bending the reinforcing bar or tilting the anchor pin. Cannot be confirmed as prescribed, and further, it cannot be confirmed from the outside whether or not a layer of mortar or the like is formed around the reinforcing bar with a prescribed thickness. Was rarely formed.

The present invention has been made in view of such circumstances, and it is possible to easily form a grid-shaped method frame according to standard dimensions without requiring skill, and at the same time, the positioning of the reinforcing bar at that time can be performed. It is an object of the present invention to provide a frame body for forming a legal frame and a method for constructing a legal frame using the frame body, in addition to being surely achieved, capable of significantly increasing the legal frame strength.

[0007]

A frame for forming a legal frame according to the present invention, which has achieved the above object, is installed on a slope in a grid pattern and is sprayed with concrete or mortar to form a legal frame. And a plurality of horizontal wire rods having a pair of legs on both sides in the longitudinal direction, and a plurality of vertical wire rods connecting the legs of the horizontal wire rods to each other, and the height of the horizontal wire rods. It is characterized in that the reinforcing bar erection material is provided in the direction intermediate portion and in the direction across the pair of legs of the horizontal wire in the front view.

The above-mentioned reinforcing bar construction material is fixed, for example, over one leg body and the other leg body in the width direction of the frame body, or over one leg body in the width direction of the frame body and the other vertical wire member. Alternatively, the frame body is fixed to one vertical wire member in the width direction and the other vertical wire member in the width direction.

Alternatively, one end of the reinforcing bar erection material is movably held by one leg of the horizontal wire, and the reinforcing bar erection material is allowed to float, and a locking portion formed on the other end side of the horizontal wire is provided. Locking to the other leg or vertical wire, or, while holding one end side of the rebar erection material movably on one vertical wire in the lengthwise direction of the horizontal wire, the rebar erection material is allowed to float, The locking portion formed on the other end side is provided by locking the other vertical wire in the lengthwise direction of the horizontal wire.

Needless to say, the front view shape of the frame body is determined by the shape of the horizontal wire rod, that is, the shape of the horizontal wire rod is not limited, but as the horizontal wire rod, for example, a pair of legs is used. If it is assumed that it is extended diagonally downward from both sides in the length direction of the linear ceiling, the frame will be trapezoidal in front view, and the horizontal wire will be arcuate or semicircular and its length If the arcuate portions on both sides in the vertical direction are legs, the frame will have a semi-cylindrical shape when viewed from the front, or as a horizontal wire, a pair of legs will extend vertically downward from both sides in the lengthwise direction of the linear ceiling. If it is provided, the frame body has a U-shape in a horizontal shape and has a gate-like shape in a front view.

Further, the method frame construction method in the present invention is a method method frame construction method using the frame body, wherein the frame body is installed in a lattice pattern on the slope and the reinforcing bars are erected on the reinforcing bar installation material,
After that, concrete or mortar is sprayed so as to embed the reinforcing bars to form a lattice-shaped frame.

[0012]

According to the above characteristic structure, the frame bodies are installed in a grid pattern on the slope at a predetermined pitch, and the reinforcing bars are erected on the reinforcing bar installation members provided in the middle portion in the height direction of the horizontal wire. By spraying a mortar or the like so as to embed them, a predetermined lattice-shaped frame is formed on the slope.

At this time, in addition to the position of the reinforcing bar being determined by the reinforcing bar erection material, since the frame serves as a guide for the spraying width and spraying height of the mortar etc., the height and width dimensions of the frame are If the installation position of the rebar erection material is set in advance based on the quality control standard for obtaining the grid-like method frame of the required strength, the mortar can be simply embedded in the vertical and horizontal frames including the rebar. It is possible to easily form a lattice-shaped method frame having a predetermined size and strength in a state where the reinforcing bar is embedded with a covering thickness of a predetermined size, without requiring any skill, simply by spraying the above.

The above-mentioned reinforcing bar erection material not only serves for the erection of the reinforcing bar, but also functions as a strength member for preventing the spread of the frame body in the width direction, so that the frame body can be stably installed on the slope. It will be excellent in terms of aspects, which in turn leads to an increase in the strength of the legal framework itself.

As described above, when the frame body has a trapezoidal shape or a semi-cylindrical shape when viewed from the front, the frame body itself has an excellent function in terms of installation stability on the slope, and further, It goes without saying that the above configuration is suitable for stacking and transporting the frame bodies, and at this time, if the reinforcing bar construction material is provided so as to be movable, and if it is folded to the leg side of the horizontal wire. Needless to say, it will be even better in terms of transportation.

[0016]

When spraying the mortar 8 and the like,
It is important that the sheet 9 is laid in the lattice-shaped portion surrounded by the vertical and horizontal frames 4 and 5 to cure the non-sprayed portion such as the mortar 8. Then, after spraying the mortar 8 and the like, the sheet 9 is removed, and in the curing portion from which the sheet 9 is removed, various seeds and fertilizers such as turf grass, wild grass, and shrubs, soil, organic materials, and water retention materials (soil). The vegetation material 1 containing the improved material) is sprayed to produce the vegetation material 1
While protecting the runoff of 0 with the grid-shaped method frame 1,
The various seeds contained in (1) are germinated and grown within the legal frame 1. In addition, a greening form may be adopted in which a vegetation bag loaded with a vegetation material is arranged on the curing portion.

Next, the structure of the vertical and horizontal frame bodies 4 and 5 used in the above-mentioned method frame construction method will be described with reference to FIGS. 2 to 4. To be stable in the installation posture and to be carried by stacking,
Both are formed in a trapezoidal shape as viewed from the front, that is, a trapezoidal horizontal wire rod 11 in which a pair of legs 11b extend obliquely downward from both sides in the length direction of a linear ceiling portion 11a, and A plurality of wire rods 11 are made up of a plurality of vertical wire rods 12 that connect the leg bodies 11b to each other, and one leg body 11b of a predetermined horizontal wire rod 11 has a pair of leg bodies 11b, 11b.
A reinforcing bar erection member 13 having a length of b is provided movably in the middle of the horizontal wire 11 in the height direction.

Specifically, the ceiling portion 11a of the horizontal wire 11 has a length of about 18 cm, the dimension between the lower ends of the pair of legs 11b, 11b is about 30 cm, and the height thereof is 10 cm.
The horizontal wire 11 is welded in the longitudinal direction of the vertical wire 12 at a pitch of, for example, about 20 cm. The length of the vertical wire 12 (that is, the length of the vertical and horizontal frames 4, 5 alone) is about 140 to 240 cm, and is lower than the upper end of the leg 11b. Four are welded at a pitch of about 3 cm.

The reinforcing bar installation material 13 is, for example, one of the frame bodies 4 and 5.
When the length of the span is 150 cm, two pieces are provided at a pitch of about 50 cm in the middle part in the length direction,
One leg 11b of the predetermined horizontal wire 11 is movably attached around the loop 13a at one end thereof in the direction of the arrow, and the other leg 11b of the horizontal wire 11 is attached at the other end. On the other hand, a locking portion 13b that is locked and coupled from above is formed on the vertical wire 12 near it.

The horizontal wire member 11, the vertical wire member 12, and the reinforcing bar installation member 13 are made of, for example, a wire having a diameter of about 4 mm and subjected to anticorrosion treatment, and the reinforcing bar installation member 13 is provided with vertical and horizontal frames. Vertical wire 1 is usually made with a numbered wire so that it does not get in the way when stacking and transporting 4, 5
It is held in a folded position along the line 2.

As is apparent from FIG. 3, the vertical frame body (hereinafter, referred to as vertical frame body) 4 has a rectangular shape in a side view, but the horizontal frame body (hereinafter, horizontal frame body). The side view shape of No. 5 has the following special structure. That is, as shown in FIGS. 2 and 4, the vertical frame member 4 which is located on one side in the lengthwise direction of the horizontal frame member 5 in the installation state on the slope A is relatively opposed.
Slanted end portion 5 with a slanting angle approximately the same as the leg body 11b of
a is formed, and a plurality of vertical wire rods 12 forming the horizontal frame body 5 are made to extend outward from the outermost horizontal wire rod 11 on the other side in the lengthwise direction of the horizontal frame body 5. Then, each vertical wire 1
2 has a shape in which an extending portion 5b that projects into the leg 11b of the horizontal wire 11 that constitutes the vertical frame 4 is formed on the tip side of 2.

When forming the inclined end portion 5a on the horizontal frame body 5, for example, the horizontal wire 11 at one end in the longitudinal direction of the horizontal frame body 5 is connected to the leg body 11b of the trapezoidal vertical frame body 4. The horizontal wire 11 can be easily formed by combining and integrating the horizontal wire 11 and the vertical wire 12 so that they have the same inclination angle.

When forming the lattice-shaped method frame 1 on the slope A, as shown in FIG. 1, first, the pre-shaped slope A is formed.
A mesh body 2 such as a rhombic wire mesh having a mesh size of about 5 to 6 cm is laid on this, and the mesh body 2 is appropriately fixed by an anchor (not shown), and the span length and frame width of the vertical and horizontal frame bodies 4 and 5 are fixed. The water threads 14 are stretched in a grid pattern at a pitch based on the total size of the water threads 14, and the reinforcing bars 3 are arranged on the mesh body 2 along the water threads 14, and a plurality of water threads 14 are placed at the center. The vertical frame body 4 is installed, the horizontal frame body 5 is installed between the vertical frame bodies 4 and 4, and the lattice frame body 6 is formed by the vertical and horizontal frame bodies 4 and 5.

As described above, the horizontal frame body 5 is inclined at one side in the longitudinal direction of the horizontal frame body 5 at an inclination angle substantially the same as that of the leg body 11b of the vertical frame body 4 which is relatively opposed to the horizontal frame body 5. The end portion 5a is formed, and on the other side in the length direction of the horizontal frame body 5, an extension portion 5b is formed by extending each of the vertical wire rods 12 forming the horizontal frame body 5 to the outside. Therefore, as shown in FIG. 5, the entire horizontal frame body 5 is lifted up, and as shown in FIG. The part 5b is thrust into the leg 11b of the one vertical frame body 4.

Thereafter, the entire lateral frame body 5 is rotated downward about the part where the extending portion 5b projects into the leg body 11b, and the lateral frame body 5 is moved to one side in the longitudinal direction. Provided slanted end 5
a is made to face the leg 11b of the other vertical frame body 4, and
As shown in, the horizontal frame body 5 is installed between the vertical frame bodies 4 and 4. As described above, after the horizontal frame body 5 is installed between the vertical frame bodies 4 and 4, as shown in FIG. 2, the inclined end portion 5a of the horizontal frame body 5 and the leg body 11b of the other vertical frame body 4 are provided. And a portion of the horizontal frame 5 extending from the horizontal frame body 5 is bound by a wire rod 15 or the like.
Then, the leg 11b of the one vertical frame body 4 is bound by a wire rod 16 or the like, and the vertical frame bodies 4, 4 and the horizontal frame body 5 are combined and integrated.

Next, the reinforcing bar 3 previously placed on the mesh body 2 is lifted up, and the reinforcing bar erection member 13 is allowed to float (see FIGS. 3 and 4) at the lower part thereof, as shown in FIGS. To
The engaging portion 13b of the rebar erection material 13 is engaged and connected to the other leg 11b of the horizontal wire 11 to the vertical wire 12 near the leg 11b from above, and is connected to the center of the width of the rebar erection material 13. Reinforcing bar 3 is mounted, and reinforcing bar erection material 13 and reinforcing bar 3 are connected and integrated by wire rod 17 or the like, and this reinforcing bar 3 is fixed to slope A by anchor pin 18, and another reinforcing bar 7 is vertically and horizontally arranged. The frame members 4 and 5 are placed on the center of the width of the ceiling portion 11a, and the reinforcing bars 7 are joined and integrated with the ceiling portion 11a by a wire rod 19 or the like.

Then, a measuring pin 20 which serves as a pointer for spraying the mortar 8 and the like with a predetermined covering thickness is placed on the upper reinforcing bar 7, and then the vertical and horizontal frame bodies including the reinforcing bars 3 and 7 are mounted. The lattice-shaped method frame 1 is formed by spraying a low-slump mortar 8 having a water content of about 7 to 8% by a mortar gun machine or the like so as to embed 4,5.

At this time, in addition to the positions of the reinforcing bars 3 and 7 being determined by the vertical and horizontal frames 4 and 5, the vertical and horizontal frames 4 and 5 serve as a guide for the spray width of the mortar 8 and the like. Since the spraying height of the mortar 8 and the like is determined by the inspection pin 20, by simply spraying the mortar 8 and the like including the reinforcing bars 3 and 7 so that the vertical and horizontal frames 4 and 5 are embedded, Thus, it is possible to form the lattice-shaped method frame 1 having a predetermined size and strength in a state where the reinforcing bars 3 and 7 are embedded in the covering thickness.

That is, in this embodiment, the height dimension of the reinforcing bar 3 floated by the reinforcing bar installation material 13 from the slope A is 5c.
m, and the height dimension from the slope A of the reinforcing bar 7 floated by the ceiling portion 11a of the horizontal wire 11 is 10 cm so that the dimension between the upper and lower reinforcing bars 3, 7 is 5 cm or more,
Then, the lower end width is about 30 to 40 cm and the height is 15 so that the periphery of these reinforcing bars 3 and 7 is surrounded by the mortar 8 and the like with a predetermined thickness and a predetermined width (each 5 cm or more).
The lattice-shaped method frame 1 having a size of about 18 cm is formed.

In the embodiment described above, the inclined end portion 5a is formed on one side in the lengthwise direction of the horizontal frame body 5, and the extension portion 5b is formed on the other side in the lengthwise direction of the horizontal frame body 5. However, both sides in the length direction of the horizontal frame body 5 are formed into inclined end portions 5a, 5a together, and the horizontal frame body 5 is inserted from above between the vertical frame bodies 4, 4.
A means for binding the horizontal frame body 5 and the vertical frame body 4 with a wire rod or the like may be adopted.

The end portions of the horizontal frame body 5 are machined in this manner because the vertical frame body 4 with which the end portions of the horizontal frame body 5 face each other has a trapezoidal shape in a front view. When the horizontal wire rods 11 forming the frame bodies 4 and 5 are, for example, arcuate or semicircular and the arc portions on both sides in the length direction thereof are the leg bodies 11b and 11b, the frame bodies 4 and 5 are front surfaces. Needless to say, it is desirable to process at least one end of the horizontal frame body 5 so as to match the arcuate leg body 11b, since it is a semi-cylindrical shape as viewed.

Alternatively, a pair of legs 11 may be used as the horizontal wire 11.
If b and 11b are extended vertically downward from both sides in the length direction of the linear ceiling portion 11a, the frame members 4 and 5 are
Is a gate shape in a front view with the U-shape lying sideways,
Alternatively, if the ceiling portion 11a in this configuration is curved upward, the frames 4 and 5 have an arch-gate shape in a front view, and therefore, the vertical and horizontal frames 4 and 5 have a side view. It may be formed in a simple rectangular shape.

Further, one end side of the reinforcing bar installation material 13 is movably attached to one leg 11b of the horizontal wire 11, and one end side of this reinforcing bar installation material 13 is attached to the horizontal wire 11. The vertical wire 12 on one side in the length direction is movably held, and at the other end of the reinforcing bar installation member 13, the reinforcing bar installation member 13 is attached.
It is also possible to have a structure in which the locking portion 13b that causes the horizontal wire rod 11 to move and is locked to the other vertical wire rod 12 in the lengthwise direction of the horizontal wire rod 11 is formed.

As described above, when the reinforcing bar installation material 13 is movably engaged, the reinforcing bar installation material 13 of the horizontal wire 11 can be used when the frames 4 and 5 have a trapezoidal shape or a semi-cylindrical shape in front view. As described above, it is suitable for stacking and carrying surfaces of the frames 4 and 5 if folded to the side of the legs 11b, but whatever the shape of the frames 4 and 5, that is, the frames 4 and 5. 5
Is a trapezoidal shape or a semi-cylindrical shape in a front view, or a gate shape or an arch gate shape in a front view in which the U-shape is laid down sideways, the reinforcing bar installation material 13 is used for the frame members 4, 5 and 5. In the width direction on one leg 11b and the other leg 11b, or on the one side in the width direction of the frames 4 and 5 and the other vertical wire 12 or in the frame 4 , 5 in the width direction on one side of the vertical wire 12 and the other vertical wire 12 may be fixed.

As the above-mentioned fixing means, for example, a method of binding or welding with a wire rod can be selected, but as shown in FIG. 10, for example, the inverted U-shaped locking portions 13 are provided on both sides of the reinforcing bar construction material 13.
c and 13c are formed by bending, for example, and the locking portion 13
A fixing means for fitting the c and 13c onto the vertical wires 12 and 12 from above can be adopted, and in this case, the attachment and detachment is easy.

Further, in the above-mentioned embodiment, the mesh body 2 is laid so as to crawl on the slope A, but as shown in FIG. 11, the mesh body 2 is lifted and the binding wire 17 or The wire rod 21 is separately connected to the reinforcing bar 3 and the reinforcing bar erection member 13 to float the net body 2, or FIG.
As shown in FIG. 5, it is possible to make changes such as floating the mesh body 2 using an appropriate spacer 22. Examples of the spacers 22 include “Slope protection lath spacer” of the applicant's design registration application No. 4418 of 1988, and “Spacer pin” of Japanese Utility Model Publication No. 5-42118 disclosed by the present applicant. It can be suitably implemented.

In the above embodiment, the reinforcing bars 3 and 7 are bound to the reinforcing bar installation material 13 and the ceiling portion 11a by the wire rods 17 and 19, but as shown in FIG.
3 and a central portion of the ceiling portion 11a can be formed by forming a recessed portion a for fitting a reinforcing bar, and the reinforcing bars 3 and 7 can be fitted and held in the recessed portion a. Therefore, the reinforcing bars 3 and 7 may be bound together.

Further, in the above embodiment, the two reinforcing bars 3 and 7 are provided on the upper and lower sides, but as shown in FIG. 14, the means for holding the reinforcing bars is optional, but the reinforcing bar installation material 13 and the ceiling part It is also possible to adopt a mode in which two reinforcing bars 3, 3, 7 and 7 are provided at a predetermined interval on each of 11a.

Although not shown, when the height of the method frame 1 is made low, the reinforcing bar 7 on the ceiling 11a side is omitted and the reinforcing bar 3 is provided only on the reinforcing bar erection material 13.
Even if the legal framework 1 is formed in any of these forms, based on the quality control standards obliged by the current civil engineering standards, the covering thickness of the reinforcing bar by mortar 8 etc. is 5 cm or more from any surface of the reinforcing bar. It goes without saying that the dimensions are set so that

In each of the above embodiments, the shape of the horizontal wire in front view may be changed to various shapes as shown in FIG.

Further, the shape of the reinforcing bar installation material is not limited to the above-mentioned one, and various shapes such as those shown in FIG. 16 can be adopted.

Further, one end or both ends of the reinforcing bar installation material may be positioned at or near the base of the leg of the horizontal wire (see FIG. 17). In some cases, one end or both ends of the reinforcing bar installation material may be connected to the horizontal wire. It may be located at the end of the ceiling (see FIG. 18).

Further, as shown in FIG. 19, an outward or inward sinking prevention piece 30 may be provided at the lower end of the leg of the horizontal wire.
