Abstract

PURPOSE:To improve the durability of a basket frame and an upper cover frame, by a method wherein they are connected by rotatably fitting a spiral metal fitting to a beam reinforcing bar for the upper part of the basket frame and a side edge reinforcing bar for the upper cover frame, which bar is parallel to the beam reinforcing bar. CONSTITUTION:At each of four corners, while a spiral metal fitting 4 is being turned so as to wrap a beam reinforcing bar for the upper part of a basket frame 1 and a side edge reinforcing bar for the upper cover frame 3, which bar is parallel to the beam reinforcing bar, the top end of the spiral metal fitting 4 is driven forward through meshes 5. When the basket frame 1 and the upper cover frame 3 are disconnected with each other, the spiral metal fitting U is reversely turned and is removed from them. The basket frame 1 and the upper cover frame 3 are carried to a site, and cobble stones are filled in the basket frame 1 at a dry riverbed or the like, following which the upper cover frame 3 is placed on the basket frame 1, and the four corners each are bound with the spiral metal fittings 4. These units are stacked one by one on a waterway revetment, and a revetment wall is constructed extending over required distance.

Description

Detailed Description of the Invention

[0001]

[Industrial field of use] In the watercourse revetment, etc., the stones in the basket frame are washed out at the place where the running water is inundated, and the stones do not serve as the watercourse revetment. In order to prevent this, the upper frame is fixed to the basket frame to prevent the outflow of the scouring stones from the scouring.

[0002]

2. Description of the Related Art The basket frame method has no upper frame because it is used for a retaining wall and a slope. If there is no upper frame at the place where the running water is inundated, such as a waterway or a seawall, the inner stone will be washed out and will not serve as a waterway seawall. Therefore, an upper frame has come to be attached to a basket frame for water channel protection.

[0003]

The attachment of the upper frame to the basket frame has generally been carried out by using a tool such as pliers to bind the upper frame with a wire or string. It is an object of the present invention to eliminate this troublesome and troublesome work.

[0004]

[Means for Solving the Problems] By attaching a spiral metal fitting to the connection between the basket frame and the upper frame by rotationally fitting a spiral metal fitting to the beam reinforcing bar on the upper part of the basket frame and the edge reinforcing bar of the upper frame parallel thereto. Made it possible to easily assemble and construct on site without using.

[0005]

[Operation] The upper frame is placed on the basket frame, and the spiral metal fittings are rotationally fitted at the four corners of the upper frame over the beam rebars of the basket frame and the edge rebars of the upper frame. For fitting, the spiral metal fittings are simply rotated by hand by winding the beam reinforcing bars and the edge reinforcing bars at the tip of the metal fittings.

When the spiral metal fittings are fitted in the four corners, the upper frame is completely attached to the basket frame, the scouring of the filling stones is prevented, and when the spiral metal fittings are attached to one side, the upper frame is hinged. It can be opened and closed, and the choice is arbitrary, and the number of spiral metal fittings to be attached is not limited, but it is usually four corners.

[0007]

EXAMPLE A front view of FIG. 1 shows a mode in which the basket frame / upper frame of the present invention is used for water channel protection. Even when used for such a waterway revetment, the filling stone (2) is thrown into the basket frame (1), the upper face frame (3) is covered, and the filling is performed by the spiral metal fittings (4) to join the filling stone. Since the outflow of scouring in (2) is prevented, the basket frame can be used for waterway protection. An embodiment of the present invention in which the upper frame (3) is attached to the basket frame with the spiral metal fittings (4) simply without using tools will be described below.

An embodiment in which the top frame (3) is placed on the basket frame (1) and the spiral metal fittings (4) are fitted at the four corners of the top frame to connect the two is shown in the perspective view of FIG. A filling stone is packed inside, but it is omitted in the figure. As the center filling stone, a 10 cm-sized ground stone that is commonly found in Kawara is used.

A state in which the spiral metal fitting (4) is rotationally fitted into the beam rebar 1'above the basket frame and the edge rebar 3'of the upper frame is shown in a partial side view of FIG. 3 and a front view of FIG.

At the tip of the spiral metal fitting (4), both the beam reinforcement 1'above the basket frame and the edge reinforcement 3'of the upper surface frame parallel to this are wound, and the mesh (5) is rotated while the spiral metal fitting 4 is rotated. ) Is sewn and pushed forward, the metal fittings can be easily fitted.

Generally, the spiral metal fitting (4) is preferably made of steel bar having a diameter of about 6 mm, and a spiral length of about 5 cm to 10 cm is sufficient. The inner diameter of the spiral must be such that the cage frame beam rebar 1'and the upper frame rim rebar 3'can be wound together, and if the diameter is too large, it will rattle after mounting and must be appropriately determined. The tip of the spiral metal fitting (4) should be sharpened.

Needless to say, the connection between the cage frame (1) and the top frame (3) can be released by rotating the spiral metal fitting (4) in the opposite direction to the connection.

The basket frame / top frame (1) / (3) of the present invention having the above-mentioned structure is carried to the site, and the top frame (3) is packed by burying the ground stone in the basket frame at the site such as a river. Place it on a caged cage frame (1) and bind the four corners with spiral metal fittings (4).
As shown in Fig. 5, the revetment wall is built up over the required distance to construct a revetment wall. Since the upper frame (3) is connected to the basket frame (1) by the spiral metal fittings (4), even if it is flooded with running water, the filling stones are washed out and do not serve as a revetment. There is no such thing.

It should be noted that the spiral metal fitting (4) is removed and the upper frame (3) is removed, so that the cage frame (1) can be easily used as a retaining wall or a slope.

[0015]

As already understood, the method of using the spiral metal fitting (4) for connecting and disconnecting the cage frame (1) to the upper frame (3) is extremely rational, and it is possible to use a cord or a rope. It is less troublesome than binding and does not require any tools. Also, it is simpler and cheaper than using a hinge, a clasp, etc. The appearance is not bad, and above all, the effect of being highly durable and the like is extremely great in the environment for revetment of waterways.
