Description

  The present invention relates to a gabion, and more particularly to a gabion structure that can improve work efficiency when laying on a slope (inclined ground).

  As shown in FIG. 14, the gabion 1 may be used when performing civil engineering work for the purpose of reinforcing the slope (inclined surface) Q or greening. A gabion (drain porcelain) 1 is formed by combining a bottom material, a side material, and an upper cover material in which a metal net is arranged on a frame material formed using a thick metal wire. The top cover material is arranged by filling the stone material, and this is laid on the slope Q.

  Conventionally, when installing the gabion 1 on the slope Q, first bring the parts of the gabions before assembly to the flat field P without inclination, prepare the required number by assembling the bottom and side surfaces on the site (flat field), then the crane The gabion 1 was moved to the slope Q by a car or the like, and the gabion 1 was fixed by an operator.

  Next, an operation of filling the laid gabion 1 with a stone is performed. Also in this case, the stone is moved and filled by a crane truck or the like.

  Next, the filled gravel is leveled, rolled, and the upper cover material is covered on the upper surface, and then the upper cover material is bound and fixed to the side material by an appropriate means (for example, Patent Document 1).

  The gabion 1 has advantages such as excellent water permeability, high flexibility, and adaptability to ground changes. When installed on the slope (slope) Q, civil engineering work such as effective discharge of spring water and seepage water, prevention of erosion of the ground surface, good calming of soil spraying, and greening Indications suitable for Recently, the spread of highly corrosion-resistant wire has expanded the application scenes other than slopes.

  The problem is the construction cost and safety when laying a gabion on the slope.

  Conventional gabions are assembled on a flat ground, moved to the slope, laid, and then filled with stones on the slopes. Filling stones, rolling, and fixing the top lid on slopes. The work is slower in processing speed than work on a flat field. The only way to shorten the work period is to increase the number of personnel. However, if the work is carried out by the same number of people, the work period cannot be shortened, so it is difficult to reduce the construction cost.

  Further, it has been difficult to ensure safety on the slope of the conventional gabion. A lot of workers are placed on the slopes, and installation of gabions, filling of stones, leveling of stones, rolling, and closing of the top cover are carried out for a long time. Although it may be necessary for the number of people, it takes time to prepare for the work, such as driving anchors in places where there are few trees to moor the rope. Because.

  Therefore, an object of the present invention is to enable efficient and safe laying work of gabions arranged on a slope.

  In order to achieve the above object, the gabion according to the present invention has two or more lifting metal fittings disposed on a gabion body formed by a bottom material, a side material, and an upper lid material in which a wire mesh is disposed on a bone line. The lifting bracket includes a lower surface support portion that supports the bottom of the bottom surface material, a vertical portion raised from an end portion of the lower surface support portion, and a lifting hook on an upper end portion of the vertical portion. The locking portion is positioned above the upper lid member, and the lifting metal fitting is disposed at least near both left and right end portions of the bottom surface material. 1).

  Since the gabion according to the present invention is provided with a lifting metal fitting, it can be lifted and moved via a heavy machinery vehicle (such as a crane truck) after being filled with stone.

  The lifting metal fittings are arranged in the vicinity of the left and right ends of the bottom member of the gabion, but when the gabion is large, it can be arranged in an appropriate number in the center. Since this lifting metal fitting is provided with a lower surface support portion, even when the gabion is filled with stones and then lifted, the lower surface support portion supports the bottom material of the gabion from below to minimize deformation of the gabion. Since the latching portion of the lifting metal fitting is positioned above the upper lid member, the lifting by the heavy machinery can be performed after closing the upper lid member of the gabion.

  The lifting metal fitting is formed by bending a single iron wire, welding the butted portions of both ends of the iron wire via a metal holding material, and the holding material, In some cases, it is provided on the lower surface support portion of the lifting metal fitting.

  The lifting bracket needs to have the strength to lift a gabion filled with stone, but it can be bent by forming a single iron wire with a certain thickness (outer diameter). Can be molded.

  In this case, the lower surface support part that supports the bottom of the bottom material and the vertical part that rises from the end of the lower surface support part are formed, for example, by forming the wire material in parallel, and the locking part provided at the upper end part of the vertical part. A lifting metal fitting can be formed by curve-forming in an inverted U shape.

  When a single iron wire (metal wire) is bent and formed, it is necessary to join the butted portion at the end of the iron wire. The lifting metal fitting according to the present invention has a structure in which an abutment portion is provided on the lower surface support portion, and the abutment portion is welded via a metal holding member, so that external force in the pulling direction is not easily applied to the portion. Strength assurance when lifting a gabion can be increased.

  In some cases, a flat reinforcing material that suppresses the bending of the iron wire is provided in the vicinity of both ends of the lower surface support portion of the lifting metal fitting (claim 3).

  When the gabion is lifted after the stone is filled, it is easy to bend right under the hook of the lifting heavy machine, particularly in the vicinity of both ends of the lower surface support portion of the lifting bracket. There is no problem when the lower surface support portion has sufficient strength, but when forming the lifting bracket with a single iron wire, by reinforcing the vicinity of both end portions of the lower surface support portion through a flat reinforcing material, It is possible to prevent the lower surface support portion from being deformed and to allow the gabion to be safely lifted and moved. It is advantageous to reduce the manufacturing cost of gabion.

  According to the gabion according to the present invention, the stone can be lifted and moved to the slope after being filled with stones in a flat place, so that the gabion laying operation can be performed efficiently and safely.

  As shown in FIG. 1, a gabion 10 according to the present invention has two or more hoisting brackets 20 disposed on a gabion main body 11. The case where a metal fitting is arranged is illustrated.

  As shown in FIG. 2, for example, as shown in FIG. 2, three lifting brackets 20 are installed at substantially equal intervals, and the lifting bracket 20 is passed through the wire mesh of the bottom material 12 of the gabion body 11 and shown in FIG. As described above, the lower surface of the bottom member 12 is supported by the lower surface support portion 21 of the lifting bracket 20.

  Next, as shown in FIG. 4, the side members 14 and 15 are arranged in the longitudinal direction and the short direction of the bottom member 12. After that, after filling the stone material (blanking material; not shown), leveling and rolling the stone material, as shown in FIG. 5, the upper lid material 16 is covered and suspended from the wire mesh of the upper lid material 16. The upper end portion of the upper metal fitting 20 is protruded to make the gabion 10 shown in FIG. Note that the side members 14 and 15 are preferably integrated with the bottom member 12 in advance through appropriate connecting means such as a hinge. This is to facilitate the assembly work.

  More specifically, for example, as shown in FIG. 6, the lifting bracket 20 is raised from a lower surface support portion 21 that supports the bottom of the bottom surface material 12 of the gabion body 11 and an end portion of the lower surface support portion 21. The vertical portion 22 and a locking portion 23 for locking the lifting hook at the upper end of the vertical portion 22 are provided. The locking portion 23 is provided so as to protrude above the upper lid member 16 of the gabion main body 11.

  For example, the lifting bracket 20 can be formed by bending a single iron wire. In this case, the lower surface support portion 21 and the vertical portion 22 are formed so that the iron wires are in parallel, and the locking portion 23 is formed to have, for example, an inverted U shape. The lateral width of the locking portion 23 and the vertical portion 22 is set to be smaller than the maximum gap size of the wire mesh of the gabion main body 11 so that the mesh can be passed.

  Moreover, it is preferable to weld the butt | matching site | part of the both ends of an iron wire via the metal holding material 26, as shown, for example in FIG. Reference numeral 27 denotes a welded portion.

  For example, the holding member 26 is welded with the iron wire F sandwiched between two metal plate members 26-1 and 26-2. Alternatively, a hole may be formed in a metal plate material, and the end of the iron wire F may be fitted and abutted to perform welding. Reference E is a slight gap that may occur at the butted portion of the iron wire F. In order to facilitate understanding, the gap E is drawn with emphasis on the drawing.

  Returning to FIG. 6, it is desirable that the lifting bracket 20 is provided with a flat reinforcing member 28 in the vicinity of both end portions of the lower surface support portion 21 to suppress the curvature of the iron wire (F) during lifting.

  For example, as shown in FIG. 8, the reinforcing member 28 is welded after a metal flat plate (welding flat bar) is brought into contact with the iron wire F, and the metal flat plate (welding flat). Bar) is fixed to iron wire F. Reference numeral 29 denotes a welded portion.

  By providing such a reinforcing member 28, bending deformation in the vicinity of both end portions of the lower surface support portion 21 can be minimized. For this reason, even if the bottom member 12 of the gabion body 11 is bent due to the stone weight when the gabion 10 is lifted, the lifting bracket 20 is not easily deformed, and the lower surface support 21 firmly holds the bottom member 12 of the gabion body 11. Therefore, the bending deformation of the bottom surface member 12 of the gabion main body 11 can be suppressed to a minimum, and the deformation of the gabion main body 11 during lifting can be minimized.

  9 to 11 illustrate a state in which the lifting metal fitting 20 is arranged on the gabion main body 11. As shown in FIGS. 9 and 10, the lower surface support portions 21 of the lifting hardware 20 are arranged in parallel along the short direction of the gabion body 11. At least two suspension metal fittings 20 are arranged. This is because the bottom surface portion 12 of the gabion body 11 is supported by the lower surface support portion 21 in the vicinity of both left and right ends. In this embodiment, the lifting bracket 20 is also arranged at the center of the bottom surface member 12 of the gabion body 11, but the number of lifting brackets 20 is increased to three or more according to the size of the gabion body 11. May be.

  Further, as shown in FIG. 11, the end portion of the lower surface support portion 21 of the lifting bracket 20 is positioned in the vicinity of the inside of the bone line N of the bottom surface material 12 of the gabion main body 11. In this way, the bone line N and the reinforcing material 28 of the lower surface support portion 21 close to the bone line N are combined, and the bending of the bottom surface material 12 can be minimized.

  According to such a configuration, as shown in FIG. 12, the gabion 10 filled with assembly stones in the flat field P can be lifted via the heavy machine W such as a crane and moved to the slope Q. R is a rope, and S is a relay material that balances when lifting. When the rope R is locked to the lifting bracket 20, for example, a locking material (such as a hook) (not shown) is used.

  Note that when the gabion 10 is lifted, the gabion 10 has substantially the same slope as the slope Q by adjusting the length of the rope R connecting the relay material S and the gabion 10, as shown in FIG. It is desirable to lift it up. This is because, when the gabion 10 is tilted and lifted, the position adjustment when installing on the slope Q is easy and safe, and the working efficiency can be increased.

  Thus, unlike the conventional gabion laying operation, if the gabion 10 that has been packed with stones in the flat field P is moved to the slope Q by the heavy equipment W, the number of work steps on the slope Q is reduced. As a result, the efficiency of laying work is increased and the number of workers can be reduced. It is also easy to ensure safety.

  Since the lifting bracket 20 according to the present invention includes the lower surface support portion 21 that supports the bottom surface material 12 of the gabion body 11, the deformation of the gabion 10 during lifting is minimized, and the gabion 10 is filled with stone. Withstand heavy lifting with heavy equipment W The gabion 10 moved to the slope Q may be laid as it is after the lock of the rope R is released, and it is not necessary to remove the lifting bracket 20.

  The gabion according to the present invention is not limited to the above embodiment. For example, the number of the lifting metal fittings 20 may be two or more. The outer diameter of the iron wire F constituting the lifting metal fitting 20 can be adjusted as appropriate according to the number of the lifting metal fittings 20 provided. In addition, the outer diameter of the iron wire F of the lifting metal fitting 20 can be, for example, about 4 to 10 mm, and in a normal case, a wire of about 6 mm can be used.

  The lifting metal fitting 20 is not limited to one formed by a single iron wire F. Instead of the iron wire F, a wire material of another metal material may be used, and the lower surface support portion 21 and the vertical portion 22 may be formed using iron or another metal plate material instead of the iron wire F.

  The locking portion 23 of the lifting bracket 20 need not necessarily be formed in an inverted U shape. A shape that can be engaged with the locking hook, for example, an annular shape or an inverted V shape may be used, or a linear shape may be used if the width is set so as to maintain a balance when lifting.

  The gabion is not limited to a rectangular parallelepiped. The present invention can also be applied to a cube, a cylinder, or a polygon having a planar pentagon or higher.

  When a rectangular parallelepiped gabion is used, the bone line of the side member in the longitudinal direction may be fixed to the bone line of the bottom member via a hinge. Moreover, both can also be fastened and fixed via the coil material for a connection. Both may be fastened and fixed via other fixing materials.
