TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting member of a cage frame for earth retaining, which is filled with split stone or the like and arranged in a required number of rows and columns to form a retaining wall or a bank.
[0002]
[Prior art]
The cage cage frame is a box-shaped container made of welded wire mesh, etc., and is filled with a filling material such as split stone, and the necessary number of retaining walls are arranged in the horizontal and vertical directions. It is to be built on or on a bank.
[0003]
By the way, when the car cage frames are arranged in the horizontal direction or the vertical direction, it is necessary to connect adjacent car frames to prevent displacement of each other. For this reason, conventionally, the frame portions of adjacent car frames are directly connected by iron wire coils or the like, or, as shown in FIG. A grid-shaped reinforcing bar 10 meshing with the filling material 5 is arranged, and hooks 11 provided at the ends of the vertical reinforcing bars are hooked to each other and connected (Japanese Patent Laid-Open No. Hei 10-280421).
[0004]
[Problems to be solved by the invention]
However, the means for connecting the frame portions of the adjacent car frames with the iron wire coil is weak in strength, and it is not possible to prevent displacement or the like occurring between the car frames. Also, in the means for connecting the adjacent car frames 4a, 4b using the lattice reinforcing bar 10, for example, the meshing of the lattice reinforcing bar 10 with the filling material in the one cage frame 4a is weak, and the fixing is insufficient. If there is, the one lattice-shaped reinforcing bar 10 is pulled out to the other car frame 4b side and pulled out, so that there is a possibility that a displacement may occur between the adjacent car frames 4a and 4b.
[0005]
The present invention has been made in order to solve such a conventional problem, and adjacent cage cage frames are firmly connected to each other, and are connected to each other in a stable and hardly displaced cage cage frame connection. The purpose is to provide members.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the retaining cage frame connecting member of the present invention is provided in the vicinity of both ends of a bar disposed so as to straddle between the retaining cage frames adjacent to each other, and inside each of the two cage frames. A fixing portion having a shape that meshes with the filling material to be filled is provided, and connecting portions with other identical connecting members are provided at both ends of the bar.
[0007]
In addition, as a connecting member of the present invention, one end side of a bar member laid across the two adjacent retaining cage frames meshes with the filling material filled in one of the cage frames. In some cases, one or a plurality of shaped fixing portions are provided, and connecting portions with other identical connecting members are provided at both ends of the bar.
[0008]
Similarly, as another connecting member of the present invention, both ends of a rod material laid across the two adjacent retaining cage frames are formed in a hook shape, and these hooks are There is a type that has both a function as a fixing unit that meshes with a filling material filled in the inside of a car frame and a function as a connection unit with another same connection member.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is an example of an earth retaining cage frame connecting member according to the present invention. As shown in the drawing, the connecting member 1 has fixing portions 3a and 3b formed near both ends of a bar 2 of a required length, and both ends of the bar are formed as connecting portions 7a and 7b. Things.
[0010]
That is, the bar 2 is formed of a reinforcing bar having a diameter of about 13 mm and a length of about 1000 mm. The fixing portions 3a and 3b provided near the both ends of the bar 2 are provided inside the adjacent cage frames 4a and 4b, respectively. This is to be engaged with the filling material 5 such as split stone to be filled and fixed. In the illustrated example, these fixing portions 3a and 3b are formed of a steel plate into a square having a side of about 150 mm, and a through hole 3 'provided in the center portion is inserted into the bar 2 so as to be in the vicinity of the end of the bar. It is provided by welding. The shape of the fixing portions 3a and 3b is not limited to the illustrated example, but may be a flat plate such as a rectangle or a circle, or a plurality of columns 6 such as a column as shown in FIG. It may have a structure radially arranged in the vicinity of the portion.
[0011]
Both ends of the bar 2 are connecting portions 7a and 7b with the other connecting member 1, and are formed in a hook shape in the illustrated example. That is, these connecting portions (hooks) 7a and 7b are connected to each other with other similar connecting members 1 installed across the adjacent car frames 4a and 4b, as shown in FIG. The plurality of car frames 4 arranged in parallel in the left-right direction are all integrally connected. By performing such integral connection, even if some of the connecting members 1 are not sufficiently fixed to the car frame, a sufficient fixing effect can be obtained as the entire connected car frame 4. Can be. Therefore, it is unlikely that a displacement occurs between all of the connected car frames 4... Even when a local load is applied, the load is transmitted to all of the connected car frames 4 and dispersed. Deformation and displacement of the car frame are less likely to occur.
[0012]
As the shape of the connecting portions 7a and 7b, in addition to the above-described hook shape, as shown in FIG. Is also good.
[0013]
FIG. 5 shows another embodiment of the cage frame connecting member for earth retaining according to the present invention. In other words, one end of the bar 2, which is disposed between the two adjacent retaining cage frames 4 a, 4 b, has a shape that meshes with the filling material 5 filled in one of the cage frames 4 a. One or more (two in the illustrated example) fixing portions 3a are provided, and connecting portions 7a and 7b (in the illustrated example, long nuts 9) with the other same connecting members 1 are provided at both ends of the bar 2 respectively. Is adopted). As shown in FIG. 6, this connecting member 1 is disposed so as to straddle all adjacent car frames 4 arranged in parallel in the left-right direction, and is connected to each other by a long nut 9.
[0014]
FIG. 7 shows another embodiment of the cage frame connecting member for retaining the earth according to the present invention. That is, both ends of the bar 2, which is arranged so as to straddle between both adjacent retaining cage frames 4 a, 4 b, are formed in a hook shape, and these hooks are provided inside the cage frames 4 a, 4 b. The combination of the function as the fixing portions 3a and 3b that mesh with the filling material 5 to be filled and the function as the connection portions 7a and 7b with other same connecting members. As shown in FIG. 8, the connecting member 1 is provided so as to straddle all adjacent car frames 4 arranged in parallel in the left-right direction, and is connected by hooking each other's hooks.
[0015]
Each of the illustrated examples described above shows an example in which car frames installed in parallel in the left-right direction are connected by the connecting member according to the present invention. However, as shown in FIG. The plurality of car frames 4 are also stacked and installed, and the connecting member 1 of the present invention is provided so as to straddle the upper and lower adjacent car frames, and is connected, so that these car frames 4 are installed in a stacked manner. It is possible to integrally connect the car frames.
[0016]
【The invention's effect】
As described above, according to the connecting member of the present invention, in order to construct a retaining wall or a bank weir, a plurality of retaining cage frames installed in parallel in the left-right direction, or a plurality of stacked car frames in the vertical direction. The individual retaining cage frames can be integrally connected in any case.
[0017]
Therefore, a high fixing effect can be obtained as a whole of the plurality of car frames connected to each other, and the displacement between the car frames does not easily occur. Further, even when a local load is applied, the load is transmitted to all the connected car frames and is dispersed, so that the car frame is unlikely to be deformed or displaced.
