Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to seawalls, wave breaking, fishing reefs,
More particularly, the present invention relates to a two-part type assembled basket frame combining two L-shaped frames. 2. Description of the Related Art As one of cage frames used for a retaining wall or the like by filling a metal cage with a filling stone, a two-part type assembling type basket combining two L-shaped frames. There is a frame. A conventional structure of this type of cage frame will be described with reference to FIG. [0003] The two L-shaped frames 1A, 1B are formed by welding L-shaped welded wire meshes with three L-shaped column bars 2A, 2A, 2A, 2A provided on both sides and the center in the width direction.
B, 2B, and 2B are reinforced and used by abutting and connecting respective horizontal parts. In order to connect butted portions of the L-shaped frames 1A and 1B, column bars 2A and 2B provided on one of the L-shaped frames 1A are provided.
The ends of the horizontal portions of A and 2A are bent in a hook shape, and the column bars 2B and 2 provided on the other L-shaped frame 1B are provided.
At the tip of the horizontal part of B, 2B, the hook part 3,
The connecting plates 4, 4, 4 with which the 3, 3 are engaged are welded.
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. [0006] Such a two-piece type assembling basket frame can be stored small by stacking the L-shaped frames 1A and 1B in a disassembled state. It has the advantage of high transport efficiency. However, on the other hand, on the other hand, there is a disadvantage that the installation range is limited to the land represented by the retaining wall because it is impossible to hang it with the filling of the filling stone. 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 assembling basket frame combining the L-shaped frames 1A and 1B, after connecting the L-shaped frames 1A and 1B, attaching the side frames on both sides, filling the filling stone,
This will be suspended, but since the butted portions of the L-shaped frames 1A, 1B are connected only by the hook portions 3, 3, 3 on both sides and the central portion, when suspended, the filling stones 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. [0008] If it is impossible to suspend the basket with the filling stones, it is necessary to install the basket 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 hanging by a crane is not possible, it is difficult to apply 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 cage 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, wave breaking, and fishing reefs. [0010] An object of the present invention is to make it possible to hang a seawall, a wave-breaking wave, and a seawall while being filled with a filling stone in spite of being a two-split type combining two L-shaped frames. An object of the present invention is to provide an assembled basket frame that can be applied to uses such as fishing reefs. [0011] In order to achieve the above object, an assembling cage frame according to the present invention comprises three or more wire nets bent in an L-shape with a gap in the width direction thereof. L
It is constructed by reinforcing with column-shaped column bars, butting each horizontal part against each other and connecting it, and side frames on both sides
And two L-shaped frames to be used by filling the inside with the filling stones, and three or more column bars provided on one of the two L-shaped frames at the top end of the horizontal portion. The three or more screw rods attached to the L-shaped frame are continuous over substantially the entire width of the other L-shaped frame. A connecting plate that is attached to the vehicle and is provided with through-holes into which the screw rods are inserted at positions corresponding to the three or more screw rods. Are inserted into the through holes of the connection plate, and nuts are screwed into the respective screw rods, so that the butted portions are screwed at three or more places. That is, in the assembled basket frame of the present invention, the first
In addition, two L-shaped frames are reinforced by three or more L-shaped column bars arranged in parallel with a gap in each width direction.
Secondly, three or more screw rods are attached to the upper ends of the horizontal portions of the three or more column bars provided on one L-shaped frame. Third, a connecting plate that is continuous over substantially the entire width of the L-shaped frame is attached to the horizontal portion distal end portions of the three or more column bars provided on the other L-shaped frame so as to straddle the horizontal portion. . Then, the horizontal portions of the two L-shaped frames are butted together, and three or more screw rods are inserted into the through holes of the connecting plate, and nuts are screwed into the respective screw rods. With the above, it is screwed. According to such a configuration, the butted portion of the two L-shaped frames is firmly connected without any backlash over the entire width by screwing at three or more places using a connecting plate continuous in the width direction of the L-shaped frame. Is done. Connecting plate continuous in width direction and 3
Since the entire cage frame is effectively reinforced in both the vertical and horizontal directions by the column reinforcements, the strength of the entire cage frame is also high. For these reasons, the butt portion does not open even if the slab is hung with the filling stones filled, and the bottom surface is not broken. Further, 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 under the cage frame flows out is prevented. Therefore, it can be installed underwater, and also can be installed at a high place. Embodiments of the present invention will be described below with reference to the drawings.
