Description

  The present invention relates to a futon to be used for ground reinforcement, earth retaining, etc. in various civil engineering works such as residential land preparation work and slope protection work.

  This kind of futon is generally formed in a rectangular box shape with a rhombus metal wire or a welded wire mesh, and is filled with chestnut stone, earth and sand, or small-diameter stone gravel, etc., and installed on the site. In the case of filling earth and sand, stone gravel, etc., since the particle size thereof is smaller than that of the wire mesh, in order to prevent the outflow to the outside, for example, as shown in Patent Document 1, an auxiliary mesh having a small mesh is provided on the side surface. It is designed to overlap inside.

However, in the past, the above-mentioned auxiliary mesh was applied to the inside of the side of the futon jar on the site, and in that state, the earth and sand were filled using a construction machine such as a power shovel. The tilting or tilting of the auxiliary net may cause the filling operation to be hindered. In order to prevent the tilting of the auxiliary net, a plurality of parts of the auxiliary net are connected to the futon with a wire, but the work requires time and effort, and the efficiency is poor.

By attaching bone lines at the upper and lower edges of the side nets to these rings, they are attached to the heel body.

  Further, in the present invention, the heel body is formed of a rhombus wire mesh composed of a plurality of flat spiral lines, and the mounting bracket also serves as a supporting bone for reinforcement, and one clamping arm is By being inserted into the mesh of the wire mesh, it is locked to the row line, abuts against the auxiliary mesh through the row line, and the other holding arm is arranged in a non-inserted state on the mesh to It is desirable to be in direct contact with the net.

  According to the present invention, a mounting bracket having a pair of holding arms is attached to a futon bag, and the auxiliary net is interposed between the holding arms of the mounting bracket so that the auxiliary net can be easily and reliably attached to the futon bag. Can be fixed to.

  FIG. 1 shows one typical embodiment of a futon 1 according to the present invention. This futon bag 1 includes a bag main body 2 formed in a rectangular box shape by a metal net, a rectangular auxiliary net 3 having a small mesh attached along the inner surface of the side net 2b in the main bag body 2, and the auxiliary net 3 and a mounting bracket 4 for fixing the main body 2 to the main body 2. As shown in FIG. 6, the inside is filled with a filler 5 having a particle size smaller than the mesh of the wire mesh such as earth and sand or gravel. A plurality of futons 1 are arranged side by side in the front-rear and left-right directions, or stacked one above the other. In this case, the auxiliary net 3 is usually attached to the side net 2b exposed to the slope or the road among the side nets of each futon 1 in order to prevent the filler 5 from leaking out.

  The saddle body 2 includes a rectangular bottom mesh 2a, a pair of front and rear rectangular side meshes 2b and 2c, a pair of left and right rectangular side meshes 2d and 2e, and a top mesh 2f attached as necessary. The auxiliary net 3 is overlapped on the inner surface of the front side net 2b. The bottom mesh 2a, the side meshes 2b, 2c, 2d, 2e, and the top mesh 2f can be formed of a rhombus metal mesh, a welded metal mesh, a turtle shell metal mesh, or the like. In the illustrated embodiment, a rhombus metal mesh is used. . As shown in FIGS. 2 and 3, this rhombus wire mesh is formed by sequentially connecting row lines 7 formed by bending metal wires into a flat spiral shape at a bent portion 7a. Has a mesh.

  The bottom mesh 2a and the side meshes 2b, 2c, 2d, 2e and the top mesh 2f are all formed individually and connected to each other in a state where a bone line made of a wire is interposed at the boundary between them. However, in the illustrated embodiment, the bottom mesh 2a and the front and rear side meshes 2b, 2c are integrally formed by a series of metal meshes, and the left and right side meshes 2d, 2e are individually formed, and they are mutually connected. It is linked to. In this case, the bone line 8 is inserted through the boundary portion between the bottom surface network 2a and the front and rear side surface networks 2b and 2c.

  As shown in FIG. 5, the auxiliary net 3 uses a wide filament 10 formed by applying a fin-like synthetic resin coating 12 to a wire 11, and this filament 10 is arranged in the background to interweave. It is a crimped net. However, the configuration of the auxiliary net 3 is not limited to this, and ordinary wires, synthetic resin filaments, etc. can be used as long as the mesh is fine enough to prevent leakage of fillers such as earth and sand and gravel. Any structure may be used such as a wire net formed by combining them in a vertical and horizontal grid, a net made of synthetic resin, or a perforated plate.

  As shown in FIG. 4, the mounting bracket 4 has a pair of opposing linear clamping arms 4a and 4b, and is formed by bending one wire into two. Rings 4c are respectively formed at the base end where the arms 4a and 4b are connected and at the tip of each sandwiching arm 4a and 4b. The lengths of the sandwiching arms 4a and 4b are substantially the same as the height of the side net 2b of the bag main body 2. Then, the mounting bracket 4 is disposed so that the side face net 2b is vertically cut at one or a plurality of places of the side face net 2b with the base end facing downward, and the ring 4c at the lower end is provided. After inserting the bone line 8 at the lower edge of the side net 2b, the auxiliary net 3 is interposed between the sandwiching arms 4a and 4b, and the ring 4c at the tip of the sandwiching arms 4a and 4b is inserted. , 4c is inserted through the bone line 8 at the upper edge of the side net 2b so that the mounting bracket 4 is attached to the heel body 2, and the auxiliary net 3 is attached along the inner surface of the side net 2b by the mounting bracket 4. It is held and fixed in an overlaid state.

  In this case, as shown in FIGS. 2 and 3, the first holding arm 4 a of the two holding arms 4 a and 4 b of the mounting bracket 4 is inserted into the mesh of the wire mesh to pass through the row line 7. The other second holding arm 4b is preferably positioned outside the wire mesh (column line) in a state where it is not inserted through the mesh inside the collar body 2, so that the collar of the mounting bracket 4 is Attachment to the main body 2 becomes more reliable and strong. At this time, the first holding arm 4a contacts the auxiliary net 3 via the row line 7 and the other second holding arm 4b directly contacts the auxiliary net 3, so that the auxiliary net 3 It will be clamped between both clamping arms 4a and 4b together with a part.

However, both the sandwiching arms 4a and 4b are attached to the inner surface side of the side net 2b by the ring 4c and the bone line 8 in a state in which both the meshes are not inserted, and the auxiliary mesh 3 is directly connected between the sandwiching arms 4a and 4b. It may be pinched.
Further, the mounting bracket 4 is formed by using a wire having a thickness or strength equal to or greater than that of the row wire 7, thereby having a function as a reinforcing support bone for supporting an intermediate portion of the side surface network 2b. It is desirable.

  In the figure, reference numeral 14 denotes a reinforcing support bone attached to an intermediate position of the rear side net 2c. The support bone 14 is similar to the first clamping arm 4a of the mounting bracket 4 in the row line 7. It is inserted into the mesh and attached to the side net 2c by allowing the upper and lower rings 14a to pass through the upper and lower bone lines 8 of the side net 2c.

  Thus, by attaching the mounting bracket 4 having the pair of clamping arms 4a and 4b to the futon 1 and interposing the auxiliary net 3 between the clamping arms 4a and 4b of the mounting bracket 4 in a clamping state, the auxiliary net 3 Can be easily and reliably fixed to the futon 1.

  The fitting 4 and the auxiliary net 3 are attached to the side net 2b when the bone wires 8 and 8 are inserted into the upper and lower edges of the side net 2b when the futon 1 is assembled or when the side net 2b is formed. However, as another attachment method, the bone wires 8 and 8 are inserted into only the ring 4c at the base end portion of the mounting bracket 4 and the ring 4c at the distal end portion of the first holding arm 4a. The metal fitting 4 is attached to the main body 2 in a semi-attached state in which the second holding arm 4b is openable and closable, and assists between the holding arms 4a and 4b when filling with earth and sand or stones at the installation site. After the mesh 3 is interposed, the ring 4c at the tip of the second holding arm 4b may be coupled to the ring 4c at the tip of the first holding arm 4a or the bone line 8 directly or using a wire or the like.

  In the above embodiment, the mounting bracket 4 is formed by bending one wire into two, and the pair of sandwiching arms 4a and 4b are integrally connected, but these sandwiching arms 4a and 4b May be separated from each other. In this case, the rings 4c are formed at the upper and lower ends of the holding arms 4a and 4b, respectively. In addition, the mounting bracket can be formed using an appropriate wire other than the wire.

  Moreover, in the said Example, although the auxiliary | assistant net | network 3 is overlapped by the side net | network 2b of the front part of the bag main body 2, this auxiliary | assistant net | network 3 is the front-and-rear both-sides net | network 2b, It can also be attached to 2c. Alternatively, instead of the front and rear side nets 2b and 2c, they can be attached to one or both of the left and right side nets 2d and 2e, or can be attached to the front and rear and left and right side nets, respectively.
