Abstract

PURPOSE:To permit the application of slope frames even to overly uneven ground by a method in which four L-shaped plates are assembled into a square frame and pins are provided on both ends of the plates in such a way as to enable the plates to move rotationally. CONSTITUTION:Each of plates 1 of a belt form having parallel two sides is shaped into an L form by bending the central part of them to a right angle. Four plates 1 are assembled into a square frame, and the adjacent plates 1 are rotatably attached through pins 2 to both ends of the plates 1 to make up a frame 3. Since each plate 1 can freely turn at the pins as fulcrums, the frame 3 can be set securely even on uneven-surfaced grounds.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a slope that does not require leveling of the slope of the earth, and a slope that does not require leveling of the slope and allows easy installation of formwork. It is something.

(Prior Art) In general, in construction work for roads, railways, embankments, etc., various legal frameworks are used to prevent the collapse of slopes due to ground surface, cutting or embankment, and to preserve the aesthetic appearance.

Normally, when constructing a slope, whether cutting or filling, the surface of the ground is leveled first to prevent fillers such as concrete from flowing out from the gap between the form and the ground.

Leveling work is generally considered easy, but depending on the location, it can be difficult and require a lot of effort.

However, with conventional legal frameworks (those made of precast concrete members, cast-in-place concrete, turf work, etc.), the quality of the leveling work is directly related to the quality of the construction, so it is not possible to easily complete the leveling work. Can not.

Therefore, in places where leveling work is difficult, such as on steep slopes, there are many problems in terms of workability and safety.

(Object of the invention) This invention was devised in view of the above-mentioned conventional problems.
To provide a legal framework that requires almost no leveling work and can be directly constructed even on uneven ground, and a legal framework that facilitates the installation of a plurality of formworks (frame bodies) in addition to the above.

(Structure of the Invention) One of the legal frames according to the present invention is made up of a plurality of strip-shaped plates and a plurality of pins, and other plates are rotatably added to the left and right ends of each plate. The method is characterized in that the formed rectangular frames are installed vertically and horizontally at predetermined intervals along the ground surface, and a hardening material is filled between the frames and hardened.

Further, the other legal frame according to the present invention is made up of a plurality of belt-shaped plates and a plurality of pins like the above-mentioned legal frame, but the other component includes a substantially inverted U-shaped connector and a connector that fits into the connector. It has a locking part. That is, a locking portion is provided on the outside of the frame, and the locking portion of one frame and the locking portion of the other frame are connected by the connecting tool while being separated by a predetermined distance, and are brought into contact with the ground. It is characterized by

EXAMPLES Below, these inventions will be explained based on examples shown in the drawings.

Drawings 1 to 4 show a frame used for construction of a legal frame according to the present invention.

In the figure, symbols 1 and 1' are plate materials, and 2 is pins 13 and 3'.
indicates the frame.

FIG. 1 shows one embodiment of the frame 3.

The plate material 1 has a band shape with two parallel sides, and is bent at a right angle near the center to form an L shape. The frame body 3 is constructed by arranging four of these plates 1 and forming a rectangular frame, and rotatably attaching adjacent plates 1.1 to both left and right ends of the plates via pins. Since each plate l is rotatable around the pin 2, the frame 3 can be installed in a manner that fully corresponds to the ground surface, even if the ground surface is level or uneven to some extent. .

Further, when assembling the frame 3, the frame 3 can be easily folded by providing a long hole along the longitudinal direction of the plate at both left and right ends of at least one of the adjacent plates 1. In other words, as shown in Fig. 2, the plate is counter-rotated at two opposing fulcrums (pins) to form a U-shape, and as shown in Fig. 3, the inner plate interposed between the outer plate and the By inserting two sheets, it can be folded into an L-shape, which is the shape of one board that makes up the frame.

Therefore, it is very convenient for transportation, etc., and does not take up much space when preparing and arranging it before construction.

Further, the plate material 1 is formed of a thin steel plate, a net frame material, etc., but it is also possible to use a special waterproof paper material.

In the above embodiments, four L-shaped bent plates 1 are used, and four pins are connected to each of the left and right ends of each plate, but the structure is not limited to this, and many more nodes may be used. may be provided.

FIG. 4 shows one embodiment thereof.

Drawings 5 to 9 show frames, connectors, etc. used in other legal frames according to the present invention.

This invention is characterized in that it has a locking part 4 (5) and a connecting tool 5 (6) compared to the above-mentioned legal frame. That is, locking portions 4 (5) are provided on the four outer sides of the frame 3, and both locking portions 4. , 4 (5, 5) has an approximately inverted U-shaped connector 6
(7) is inserted to connect adjacent frames 3 with a predetermined distance between them.

The shape of the locking part may be fixed to the plate material 1 by welding or riveting a plate or the like having a semicircular bent part as shown in FIG. 5, or a substantially cylindrical shape as shown in FIG. The formed structure may be supported by the pin 2. In addition, for example, a ring-shaped member (not shown) may also be used. Note that the locking portion can be formed into various shapes if it is made of synthetic resin or the like.

The connector may also be used as an anchor as shown in FIG. 9.

A plurality of rectangular frames configured as described above are placed on the ground surface and isolated for a predetermined distance, and concrete is placed between these frames.
A hardening material such as mortar is poured in to construct a legal framework as shown in Figure 5.

Note that after filling the hardening material, the frame body etc. may be removed, or the hardening material may be sprayed onto the side surface of the frame body to bury it. When removing the frame after construction, the work will be made easier if the pin is made of synthetic resin or the like so that the frame and the locking part can be easily removed by 4 degrees.

(Effects of the Invention) The frame used for construction of the legal frame is composed of a plate rotatably attached via a bin, and can be installed along the unevenness of the ground. Therefore, there is no need for leveling work, and for example, the work of constructing a slope on a steep slope is not only simplified and easier, but also safety is significantly improved. Furthermore, since the frame is foldable, it is very convenient for transportation, etc., and does not take up much space when preparing and arranging it.

In addition, the other frame according to the present invention has locking portions formed on the outside of each frame body constituting the formwork, and connecting tools are fitted into these locking portions to connect adjacent frame bodies. ing. Therefore, even when the slope area is large and a large number of frames are required, or when constructing a site with a steep slope, a plurality of frames can be reliably installed.

In addition, since the connector allows the predetermined distance between adjacent frames to be maintained uniformly, the overall aesthetic appearance is not compromised.
