Description

[Detailed Description of the Invention] (Industrial Application Field) This invention provides a method for constructing a slope frame that does not require leveling of the slope surface, and a method for constructing a slope frame that does not require leveling the slope surface and allows easy installation of formwork. It concerns the method of constructing the legal framework.

(Prior art) In general, in construction work for roads, railways, embankments, etc., various methods of constructing slopes have been implemented with the aim of preserving the aesthetic appearance and preventing collapse of slopes due to ground surface, cutting, or embankment. ing.

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 using 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. I can't.

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, and provides a method for constructing a slope frame that requires almost no leveling work and can be directly constructed even on uneven ground, and in addition to the above-mentioned methods. The purpose of the present invention is to provide a construction method for a legal framework that facilitates the installation of multiple formworks (frame bodies).

(Structure of the Invention) One method of constructing a legal frame according to the present invention consists of a plurality of strip-shaped plates and a plurality of pins, and each strip-shaped plate is arranged near the center so as to constitute a corner of a rectangular frame. The plates are bent at right angles to form an L-shape, and other plates are rotatably attached to the left and right ends of each plate via pins to form a rectangular frame. It is characterized in that the frames are installed vertically and horizontally at predetermined intervals along the surface, and a hardening material is filled between the frames and solidified.

The other method of constructing a legal frame according to the present invention is composed of a plurality of strip plates and a plurality of pins, similar to the method of constructing a legal frame described above, but other components include a substantially inverted U-shaped connector and a plurality of pins. It has a locking part that fits into the connector. That is, a locking part is provided on the outside of the frame, and the locking part of one frame and the locking part 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. shall be.

(Examples) Hereinafter, these inventions will be explained based on examples shown in the drawings.

Drawings 1 to 4 show a frame body used in the construction method of a legal frame according to the present invention. In the figure, symbols 1 and 1' are plate materials, 2 is a pin,
3 and 3' indicate frames.

FIG. 1 shows one embodiment of the frame 3.

The plate material 1 has a band shape with two parallel sides,
Bend the area near the center at a right angle 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 board 1 is rotatable around the pin 2, even if the ground surface has some degree of unevenness, the frame 3 can be installed in a manner that corresponds sufficiently to the ground surface. can.

Furthermore, when assembling the frame 3, the frame 3 can be easily folded by drilling 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 plate 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 addition, in the above embodiment, the plate material 1 is bent in an L shape.
Although four pins are used at both the left and right ends of each plate, the present invention is not limited to this, and more nodes may be provided.
FIG. 4 shows one embodiment thereof.

Drawings 5 to 9 show frames, connectors, etc. used in another method of constructing a legal frame according to the present invention.

This invention is characterized in that it has locking parts 4 and 5 and connectors 5 and 6 compared to the above-mentioned method of constructing a legal frame. That is, locking portions 4 and 5 are provided on four sides of the outer side of the frame 3, and both locking portions 4, 4, 5, 5
Approximately inverted U-shaped connectors 6 and 7 are inserted into the frame bodies 3 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 installed at predetermined intervals along the ground surface, and a hardening material such as concrete or mortar is poured between these frames.
A legal frame as shown in FIG. 10 is constructed.

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 facilitated if the pins are made of synthetic resin or the like so that the frame and the locking portion can be easily removed.

(Effect of the invention) The frame used in one method of constructing a legal frame according to the present invention is composed of plates rotatably attached via pins, and the frame is installed along the unevenness of the ground. be able to. 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 facilitated, 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 method of constructing a legal framework according to the present invention is to form locking portions on the outside of each frame body constituting the formwork, and to fit connectors into these locking portions to connect adjacent frame bodies. are connected. 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. Furthermore, since the connector allows a predetermined distance between adjacent frames to be maintained uniformly, the overall aesthetic appearance is not spoiled.
