2. Description of the Related Art Conventionally, when a slope is formed on a slope formed by a steep slope or a civil engineering work, in order to green the slope, a seed soil is put in the slope to make the slope green. Various greening methods have been devised, such as spraying or planting through holes formed in the slopes. Also, if the slope of the ground or slope is steep or the ground is hard, it is difficult to fix the soil, and it is difficult to maintain the planting layer permanently. At this time, a construction method is known in which a pocket-shaped formwork is assembled and shotcrete such as mortar is sprayed from the surroundings or concrete is poured to form a planting shelf to plant. The present invention relates to an improvement of a planting method for greening by forming a shelf in the latter frame.

[0003]

However, in the conventional shelf planting method, a space for planting is formed by spraying mortar or the like or casting concrete using a formwork. Enormous effort in the work,
It has disadvantages such as time and cost. The present invention has been made in order to solve such disadvantages of the prior art, and has been made to a law frame which is simple and low-cost with respect to the law frame, and in which a large number of planting shelves can be continuously attached. It is an object of the present invention to provide a planting shelf facility construction method and a planting shelf.

[0004]

According to the present invention, in order to solve the above-mentioned problems, left and right retaining plates formed around a vertical beam of a vertical frame are joined to each other at an intermediate portion between the vertical beams. is formed on the side portion, and with at least one of connected by fixing means through the insertion hole for formed a long hole for adjusting connection, to secure the lower portion of each of the earth retaining plates,
In addition, a technical means of forming a space for planting between the slope plate and the slope by connecting an appropriate portion of the earth retaining plate to the vertical beam via a connecting rod and supporting the same at a predetermined angle is employed. It is characterized by the following.

[0005]

As described above, the present invention uses left and right earth retaining plates formed around the vertical beams of the formwork instead of the conventional shotcrete and concrete construction methods using the formwork, Since the technical means of connecting at the middle part between the vertical beams and forming a space for planting with the slope is adopted, the construction work is greatly simplified, and labor, work time and cost are reduced. Reduction can be achieved. In addition, as a method of connecting the earth retaining plates, in the intermediate portion between the vertical beams of the legal frame, they are connected by fixing means via adjustable connecting insertion holes formed in the side portions of the left and right earth retaining plates. Because the method adopted, even if there is a deviation in the pitch between the vertical beams of the frame, it can be adjusted through the insertion hole for the adjustment, and if the left and right earth retaining plates are connected alternately, it will be used for planting The length of the shelves can be freely extended to an appropriate length.

The second-stage holes from above 6a and 6b also function as insertion holes for connection with the vertical beams 1 described later. Similarly, the insertion hole 5
The lowermost holes a and 6a also function as insertion holes for fixing to the cross beam 2. In the drawing, reference numerals 9 and 10 denote through holes for connection to the vertical beam 1 provided in the middle, and reference numerals 11 and 12 denote through holes for fixing to the cross beam 2.

However, when forming the planting shelf of the present embodiment , first, the cutout portions 7, 8 of the left and right earth retaining plates 3, 4 are formed.
Are fitted to the longitudinal beams 1 and the lower sides of the retaining plates 3 and 4 are
Fixed to. The lower side is fixed by inserting the concrete anchor 13 into the insertion hole 12. Next, the lateral connection of each of the left and right earth retaining plates 3 and 4 is made by matching the insertion holes 5a and 6a and 5b and 6b formed in the side portions thereof, and using fixing means such as bolts and nuts. Then, they are inserted and tightened. In this case, each insertion hole 5
Since a, 5b, 6a, and 6b are formed in long holes, it goes without saying that deviations such as the pitch between the vertical beams 1 can be adjusted by the long holes when the bolt is inserted. Before and after the connection of the retaining plates 3 and 4 in the lateral direction, the retaining plates 3 and 4 are supported at a predetermined angle with respect to the slope. In the vertical beam 1 portion, the vertical beam 1 is supported via a connecting rod by using the vertical beam 1 itself. In addition, vertical beam 1
As shown in FIGS. 1 and 2, the support at the intermediate portion between the two bolts 14 is a full screw bolt 14 horizontally mounted between the longitudinal beams 1.
And a connecting rod 16 which is mounted orthogonally to the full screw bolt 14 via the orthogonal nut member 15 and also includes a full screw bolt. That is, after the orthogonal nut member 15 is moved to a predetermined position on the full screw bolt 14, the connecting rod 16 is screwed into the orthogonal nut member 15, and the other end of the connecting rod 16 is inserted into the insertion holes 9, 10. The earth retaining plates 3 and 4 are supported at a predetermined angle by being inserted and tightened by front and rear nuts 17 and 18. Needless to say, it is desirable that these connecting members are made of a material having high strength and durability. In the figure,

In this way, when the left and right retaining plates 3, 4 are alternately arranged and the required length of the retaining plates 3, 4 are fixed to the frame, the retaining plates 3, 4 are fixed. On both sides and at an appropriate intermediate portion, a secondary product made of FRP or the like or a lateral soil retaining means (not shown) made of reinforced concrete or the like is applied, and the planting between the slope formed by this and the soil retaining plates 3 and 4 is performed. The space for planting is filled with soil, fertilizer, and the like, and appropriate plants are planted to achieve greening of the slope. In the above description, the shape of the earth retaining plate, the location and number of the insertion holes, the specific fixing means, and the like are merely examples, and it goes without saying that they can be appropriately modified as needed. The description of the procedure for forming the main planting shelf is also an example, and can be changed as appropriate. Also, regarding the long hole for adjustment,
As in the above-described embodiment, both the insertion holes of the connection portion are formed in the long holes for adjustment, or only one of the insertion holes is formed in the long hole for the adjustment, and furthermore, The length is a matter of design choice.
