Description

[Detailed explanation of the invention] (Industrial application field) This invention is a method of constructing terrace pockets for vegetation in the slopes, which is a facility for slopes to prevent and stabilize the collapse of mountains and slopes. This invention relates to a formwork device.

(Prior Art) Conventionally, in order to prevent collapse and stabilize slopes formed by steeply sloping ground or civil engineering work, a slope has been constructed on a slope of a ground. Also,
In order to plant vegetation and green the slopes, various greening methods are being implemented, such as adding soil to the slopes and spraying seeds on them.

(Problem that the invention aims to solve) However, in places where the ground or slope is steep or hard, it is difficult for the soil to settle.
A problem arises in that the vegetation layer cannot be permanently fibrous. For this reason, on steep slopes or on hard ground, vegetation work is almost never done using only legal framework facilities.

This invention is related to the facilities of the legal framework on the ground and slopes where conventional vegetation and greening are difficult.
The purpose of this project is to provide a formwork device that can easily and firmly construct terrace pockets suitable for permanent vegetation.The terrace pocket facilities allow soil to settle well and create a permanent vegetation layer. The aim is to create a

(Effects of the invention) As explained above, the formwork device of the invention has a U-shaped outer frame in which triangular side plates are bendably connected on both sides of a rectangular front plate, and a rectangular front plate. A U-shaped inner formwork is formed by bendably connecting inverted ladder-shaped side plates on both sides, and the outer formwork and the inner formwork are mutually mounted on the horizontal frame members of the legal frame structure. At the same time as facing the front plates, the side plates of the outer formwork are placed on the vertical frame members of the slope structure, the side plates of the inner formwork are placed oppositely on the slope, and the outer formwork and the inner formwork are placed oppositely. Since the structure is such that the molds and the formwork are connected to each other, the following excellent effects can be achieved.

(1) The formwork consists of an outer formwork with triangular side plates on both sides of a rectangular front plate that can be bent freely into a U-shape, and an inverted ladder-shaped side plate on both sides of the rectangular front plate. Since the inner formwork is installed in series and can be bent into a U-shape, the formwork can be erected by simply placing and fixing them on the horizontal and vertical frame members or on the slope. It can be performed easily, reliably, and with high precision, and the complicated labor such as fitting can be omitted at present, making the construction more efficient.

(2) Since both the outer and inner formwork are bendable, the formwork can be transported in a flat form and then bent and used on site, greatly reducing the labor and cost of transport. It can be reduced.

(3) Since both the outer formwork and the inner formwork are formed in a series in a U-shape, the assembly strength of the formwork is high, and therefore, inexpensive lightweight materials can be used for the formwork, and The amount of reinforcing support materials such as separators and butter materials can also be reduced.
