Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cage frame which is filled with filling stones and is used for seawalls, breaking waves, fishing reefs, piercing, retaining walls, and the like. Related to the basket frame.

[0002]

2. Description of the Related Art A cage frame used for a retaining wall or the like by filling a filling stone is roughly classified into a welding type and a non-welding type depending on the type of a wire mesh used. The welding type uses a rectangular welded wire mesh formed by combining vertical straight bars and horizontal straight bars in a grid pattern and welding. As a welding type cage frame, there is a two-part type assembled cage frame combining two L-shaped frames. The structure of the basket frame will be described with reference to FIG.

[0003] The two L-shaped frames 1A and 1B are formed by welding L-shaped welded wire meshes with three L-shaped column bars 2A, 2A, 2A and 2A provided on both sides and a center in the width direction thereof.
B, 2B, and 2B are reinforced and used by abutting and connecting the respective horizontal parts.

In order to connect the butted portions of the L-shaped frames 1A, 1B, one of the L-shaped frames 1A has column bars 2A, 2A, 2A.
The tip of the horizontal part is bent into a hook shape,
In the other L-shaped frame 1B, connecting plates 4, 4, and 4 with which the hook portions 3, 3, and 3 are engaged are welded to the distal end portions of the horizontal portions of the column bars 2B, 2B, and 2B. Each connecting plate 4 is provided with a through hole for inserting the hook 3.

A plurality of connected L-shaped frames 1A and 1B are connected in the width direction, and the inside thereof is filled with a filling stone. Side frames are attached to the outer side surfaces of the L-shaped frames 1A, 1B on both sides in order to prevent the outflow of the filling stone.

In contrast to such a welding type, a non-welding type cage frame uses a diamond-shaped wire mesh shown in FIG. The reason why the diamond-shaped wire mesh is used in the non-welded type is that the wires are fixed to each other even without welding, and the edges are easily cleaned. By the way,
In the case of a rectangular wire mesh in which straight streaks are combined vertically and horizontally, the straight and horizontal straight streaks are not fixed without welding, and the edges are difficult to dismantle.

[0007]

The two-piece type assembled basket frame shown in FIG. 5 is a welding type using a welded wire mesh, and has essentially no high strength because the wire mesh does not extend vertically and horizontally. is there. In addition, since the L-shaped frames 1A and 1B can be stored in a small size by disassembling the L-shaped frames 1A and 1B, the storage efficiency and the transportation efficiency are high. However, on the other hand, there are the following problems.

First, although it is high in strength, it is impossible to hang it while filling it with filling stones, so that its installation range is limited to the land represented by retaining walls.

That is, in applications such as seawall protection, wave breaking, and fishing reefs, it is necessary to assemble a basket frame on land and fill the filling stones, and then suspend the basket frame with a crane and drop it into water. When suspending the conventional assembled basket frame combining the L-shaped frames 1A and 1B, the L-shaped frames 1A and 1B are connected, the side frames are attached on both sides, and then the filling stone is filled.
This will be suspended, but since the butted portions of the L-shaped frames 1A and 1B are connected only by the hook portions 3, 3, and 3 on both sides and the central portion, when suspended, the filling stone is The butting portion opens due to the load of the above, the bottom surface is broken, and the filling stone flows downward, so that the cage frame is broken. For this reason, it is impossible to hang the state where the filling stone is filled.

[0010] If it is impossible to hang a basket filled with filling stones, it is necessary to install the cage frame directly at the construction site, and the installation range is limited to the land represented by the retaining wall. It is. Also, although it can be installed on land,
If suspension by a crane is not possible, it is difficult to apply the method to retaining wall construction at high places.

Further, even if the underwater installation is possible, the connection by the hooks 3, 3, 3 may cause the basket frame to be broken due to the side resistance due to the water flow, or the L-shaped frame 1A,
Due to the gap generated at the butting portion of 1B, there is a problem that when the earth and sand below the cage frame flows out, the filling stone flows out from the gap. In any case, it is difficult to apply to applications that require suspension, such as seawalls, breaking waves, and fishing reefs.

A second problem is that a plated wire cannot be used for a welding wire mesh. For this reason, it is impossible to cope with the case where a plated product is required.

The third problem is that although the L-shaped frames 1A and 1B are relatively bulky, the L-shaped frames 1A and 1B are relatively large, so that the front and rear frames are independently connected before and after the bottom frame. The storage capacity may be inferior to that of the folding basket frame.

On the other hand, a non-welded cage frame using a diamond-shaped wire mesh has extremely low strength as compared with a welded wire because the diamond-shaped wire mesh extends in the vertical and horizontal directions. Impossible. However, it is possible to use a plated wire, and a foldable type in which the front frame and the rear frame can be flatly folded on the bottom frame is excellent also in terms of storability. For these reasons, despite its low strength, non-welded cage frames are still frequently used.

An object of the present invention is to provide a non-weld type
It is an object of the present invention to provide a folding cage frame which is as high in strength as a welding type, can be suspended even in a state of being filled with filling stones, and has a very excellent storability.

[0016]

In order to achieve the above object, a folding basket frame according to the present invention comprises a rectangular crimp formed by combining vertical streaks of waveform and horizontal streaks of waveform alternately in a grid pattern. A bottom frame made of a wire mesh, and a front frame and a rear frame that are arranged before and after the bottom frame, each of which is made of the above-described rectangular crimped wire mesh. A first connecting rod that hinges the front frame and the bottom frame so that the front frame and the bottom frame can be pivotally connected to each other, and the rear frame and the bottom frame are wound between the rear frame and the bottom frame by being wound from both sides. And a second connecting rod rotatably hinged.

[0017] If necessary, a pair of side frames which are disposed on both sides of the bottom frame and are each formed of the above-mentioned rectangular crimped wire mesh, and an end of a vertical streak of the side frame between each side frame and the bottom frame. By wrapping the ends of the horizontal streaks of the bottom frame from both sides, it is possible to provide a pair of third connecting rods that rotatably hinge connect the side frames and the bottom frame.

In the folding basket frame of the present invention, first,
A rectangular crimped wire mesh formed by combining vertical streaks and horizontal streaks alternately in a grid pattern is used as the wire mesh. Since this wire mesh is a square wire mesh, it has little vertical and horizontal elongation and high strength. Further, in spite of non-welding that can be plated, vertical and horizontal corrugated lines are fixed to each other and do not disperse. Therefore, the disposition of the edge is also simplified.

Second, the front frame and the rear frame are hinged to the front edge and the rear edge of the bottom frame, respectively, and are folded flat on the bottom frame around the lower edge. Therefore, the storability is good.

Third, the bottom frame is not divided, and the front frame and the rear frame are firmly connected to each other using the respective vertical stripes. For this reason, there is no danger of a bottom crack even if the suspension is performed in a state where the filling stone is filled, and the suspension is possible. Furthermore, the cage frame is prevented from being broken due to side resistance when the underwater installation is performed, and the outflow of the filling stone when the earth and sand below the cage frame flows out is also prevented. Therefore, it can be installed underwater, and also can be installed at a high place.

・ It is wrapped around the top tier. Also, horizontal line 4
The two ends of 2, 42... Are wound around the vertical streaks 41, 41 on both sides for their disposal.

Next, a method of using the folding basket frame according to the embodiment of the present invention will be described.

In the folding basket frame according to the embodiment of the present invention, the lower ends of the vertical streaks of the front frame 20, the rear frame 30, and the side frames 40, 40 are connected by connecting rods attached to four sides of the bottom frame 10. 50, 60, 70, 70.
For this reason, the front frame 20, the rear frame 30, and the side frames 40, 4
Each of the zeros can rotate around the respective lower edge.

When used alone, as in the case of hanging use, as shown in FIG. 1, the front frame 20, the rear frame 30, and the side frames 40, 40 are set up vertically, and coiled wires or the like are formed at four corners. By joining the adjacent vertical streaks, the assembly of the cage frame is completed. Filling stone 8 in the basket frame after assembly
After filling with 0 and attaching an upper frame as required, for example, the cage frame is suspended in a crane and put into water.

The bottom frame 10 is made of a crimped wire mesh and is not divided. Front frame 20, rear frame 30, and side frame 4
Nos. 0 and 40 are firmly connected to the four sides of the bottom frame 10 because all the vertical streaks of the crimped wire mesh are wound around the connecting rods. Further, the crimped wire mesh is essentially a high-strength rectangular wire mesh and is not welded, but the vertical and horizontal streaks are fixed to each other, and there is no danger of the mesh expanding. For this reason, even if the basket frame filled with the filling stones 80 is suspended, there is no danger of a bottom crack or the like, and the cage frame can be suspended by the crane. As a result, the cage frame can be installed underwater.

Further, in a cage frame installed underwater,
Even if the earth and sand below the cage frame flows out, the filling stone 80 in the cage frame
Does not flow down. In addition, no destruction of the cage frame due to side resistance occurs.

For these reasons, the present invention can be applied not only to retaining walls, but also to seawalls, wave breaking, fishing reefs, and the like, and can also be applied to work for retaining walls at high places.

In the case of on-site land assembling of a retaining wall or the like that is not used for suspension, that is, when a plurality of car frames are used by connecting them in the width direction at their installation locations, as shown in FIG. On the front, front frames 20, 20 and side frames 40, 4
0 are connected to each other, and on the rear surface, the vertical lines of the rear frames 30, 30 and the side frames 40, 40 are connected. Connecting member 9
As 0, for example, a coiled wire can be used. After the on-site assembling of the cage frame is completed, filling is performed on the spot.

When storing the basket frame, the front frame 20, the rear frame 30, and the side frames 40, 40 are folded flat on the bottom frame 10. Thereby, the basket frame is stored compactly.

In the above embodiment, the side frames 40, 40 are attached to the side surfaces of the cage frame in consideration of the single use of the cage frame.
When such consideration is not necessary, that is, when mainly assembling and connecting on site, the side frames 40, 40 can be omitted. In this case, the connecting portion is reinforced by a brace structure or the like using a diagonal material. Separate side frames will be attached to the outer sides of the cage frames at both ends. Even when the cage frame in which the side frames 40, 40 are omitted is used alone, the side frames are separately attached to both side surfaces.

Regarding the specifications of the vertical streak and the horizontal streak constituting the crimp wire net, the wire diameter is suitably 4 to 6 mm.
An appropriate wave pitch is 10 to 30 mm. The distance between the lines may be the same as the mesh of the conventional cage frame, and is 50 to 150 m.
m is appropriate.

[0039]

As is apparent from the above description, since the folding cage frame of the present invention is a non-weld type, it can meet the demand for plating finish. Also, despite the non-welded type, the use of crimped wire netting results in essentially high strength. In addition, since the bottom frame is not divided and the front frame and the rear frame are firmly connected to each other using the vertical streaks, it is possible to suspend even the state where the filling stone is filled. Therefore, not only can it be installed on land including at high altitudes, but it can also be applied to applications that require underwater installation such as seawalls, wave breaking, fishing reefs, etc.
Its application range can be greatly expanded. Moreover,
Since the front frame and the rear frame can be flatly folded on the bottom frame, the storage efficiency is extremely excellent.
