Description

In particular, the present invention relates to a sloped embankment slope, that is, to a wall-wall-retaining retaining wall connecting member that reinforces a retaining wall . The present invention relates to a connector for wall reinforcing retaining wall material .

Conventionally, sandbags, concrete frames, and the like have been used to reinforce wall surfaces in embankments and the like, but in recent years, wire meshes have been placed on slopes to be reinforced and vegetated on the wire mesh to become green.
For example, Patent Literature 1 discloses a wall surface reinforcing member that is installed on the surface layer portion of a wall surface to reinforce the ground. The wall reinforcing member is composed of a net member and a frame member that borders the periphery thereof, the side view is U-shaped, and at least the frame member constituting the upper side of the U-shape is rotatably connected. .

In Patent Document 1, the frame members of the left and right wall reinforcing members adjacent to each other are connected to each other by a coiled connecting member, and the winding pitch of the coiled connecting member attached to the U-shaped upper side of the wall reinforcing member is a mesh-like ground. By fitting the two together by setting the mesh pitch of the reinforcing member to be a fixed multiple, and connecting to the bottom of the upper wall reinforcing member, and inserting the rod-like member into the coiled connecting member, A ground reinforcing member and an upper wall reinforcing member are connected to each other, and on the inner surface of the U-shaped vertical side portion of the wall reinforcing member, a mesh sheet and a vegetation sheet finer than the net member constituting the vertical side portion are provided. It has a retaining wall structure.
JP 2000-273868

 However, in the coil-shaped connecting member of Patent Document 1, the mesh member that constitutes the upper side of the bottom wall reinforcing member and the mesh member that constitutes the bottom overlap, and the reinforcement from the middle to the upper side is the same as that of the lower wall reinforcing member. It is described that the upper side and the bottom side of the wall reinforcing member on the upper side are connected by a coiled connecting member, a mesh-like ground reinforcing material is fitted into the coiled connecting member, and a rod-like member is inserted to prevent it from coming off. In the figure of Patent Document 1, the coil-shaped connecting member is conceptually shown.

As described above, it is presumed that the coiled connecting member of Patent Document 1 is also used for the connection between the left and right wall reinforcing members.
However, since the coil-shaped connecting member is to house the mesh beam between the left and right wall reinforcing members in the coil-shaped circle, it is necessary to rotate the coil-shaped connecting member with tens of rotations during assembly. The work efficiency was not good. In addition, since the nets can move freely in the coil circle, there was a backlash, and repeated fine adjustments were necessary to achieve linearity during construction.

Therefore, in recent years, as shown in FIG. 10, a wire clip using a U-shaped bolt C is used to tighten the mesh beam A and the mesh beam B between the left and right wall reinforcing members.
10A and 10B are explanatory views for explaining the connection state of the conventional wall reinforcing material. FIG. 10A shows the attachment state of the U-shaped bolt, FIG. 10B shows the attachment state of the washer and the nut, and FIG. (C) is an expanded perspective view which shows the attachment state of a U-shaped volt | bolt, a washer, and a nut.
First, when the U-shaped bolt C is used to fasten the left and right wall reinforcing members between the mesh beam A and the mesh beam B, the mesh beam A and the mesh beam B are inserted into the opening of the U-shaped bolt C. A and the crosspiece B are sandwiched between the opening of the U-shaped bolt C and the washer D inserted into the opening, and nuts E are screwed to both ends of the U-shaped bolt C so that the two nuts E By tightening, the U-shaped bolt C and the washer D firmly connect the left and right wall reinforcing members A and B to each other.

 However, in order to tighten the two nuts E of the U-shaped bolt C of the wire clip, it is necessary to rotate one nut E from 5 rotations to 10 rotations and, as a result, to rotate the nuts on both sides by 10 rotations or more. Tightening work efficiency was not good. In particular, tightening nuts on site in winter required two to three times as much work time as in summer. Further, if the mounting interval of the wire clip is made narrow, due to the poor mounting workability, there has been a problem that the balance with other workability cannot be maintained unless human care is taken.

Accordingly, the present invention has been made to solve such problems, and provides a connecting device for a wall reinforcing retaining wall material that improves workability and work efficiency and that is easy to produce linearity during construction. Is an issue.

Here, the lower surface mesh portion is a surface that receives the embankment on which the embankment is loaded in a plurality of layers, and is formed of a mesh surface. As the mesh, it is possible to use a wire mesh such as an expanded metal, a welded wire mesh, a plain weave wire mesh, a rhombus wire mesh, or a turtle shell wire mesh.
Further, the rising net portion is formed as an acute angle surface between the lower surface net portion and the net surface for preventing the embankment from spilling out, that is, a net surface forming a retaining wall surface. For example, the lower surface net part and the rising net part may be formed by bending one formed integrally, or may be formed separately and connected. Usually, the angle at which the lower surface net part and the rising net part are joined is about 90 degrees or less, which is an acute angle.
And the above-mentioned connecting tool is constructed by raising the surface on which the embankment is stacked in a plurality of layers as an acute angle surface between the ends of the lower surface net part formed with the net surface and between the lower surface net part. It connects between the ends of the rising net part that forms a mesh surface to prevent spillage, and more specifically, it engages with the winding holding part formed entirely of an elastic body. And the winding holding portion is an end portion in which a winding state of one turn or more is maintained in a state where the end portions of the lower surface net portion and the end portions of the rising net portion are overlapped with each other.

Between the ends of the rising net portions formed by forming a mesh surface that prevents the embankment from spilling out, between the ends of the lower surface mesh portions and / or the rising net portions In a state where the ends are overlapped with each other, the winding holding portion of the connector restrains the ends of the bottom mesh portion and / or the ends of the rising mesh portion in a winding state of one turn or more. Further, the locking portion is elastically engaged with the mesh bar on the mesh surface so that the winding holding portion does not move.
Therefore, between the ends of the lower surface net part and / or between the end parts of the rising net part between the winding state pitches of one turn or more by the winding holding part of the connector, By rotating, the locking portion can be elastically engaged with the mesh bar on the mesh surface. And when releasing the said connecting tool, the elastic engagement of the said latching | locking part is cancelled | released, it is rotated, between the edge parts of the said lower surface net | network part from between the pitches of a winding holding | maintenance part, and / or the said The end portions of the rising net portion can be separated from each other. Further, the backlash between the ends of the lower surface net part and / or between the end parts of the rising net part is limited to within a winding diameter of one turn of the winding holding part, and the lower surface net part and / or or linearity of the start-up network part is easy to put out.
Therefore, the workability and work efficiency of the connection between the end portions of the bottom mesh portion and / or the end portions of the rising mesh portion are improved, and the bottom mesh portion and / or This makes it easy to obtain the straightness of the rising net portion.

In addition, the winding holding part formed at one end where the winding state of one turn or more is maintained has a pitch between the ends of the lower surface net part and / or between the ends of the rising net part. And having a front end bent into a substantially crank shape or a substantially U-shape, the pitch between the ends is substantially α-shaped. It has a structure that can be easily fitted and restrained by the difference in angle, and when the tip is bent into a substantially crank shape or a substantially U shape and is elastically contacted with the mesh bar of the mesh surface, an external force Therefore, even if it is moved after assembly at the construction site, the connected portion does not easily come off.
In addition, since the locking portion is bent in a substantially crank shape or a substantially U shape, when it is elastically contacted with the mesh bar of the mesh surface, it is elastically contacted so as not to move easily by an external force. Even if it is moved after assembly at the construction site, the connected part will not easily come off.
And since the substantially (alpha) -shaped winding holding | maintenance part formed in the one end part by which the winding state of 1 turn or more is maintained is made into 1 turn or more and 2 turns or less, the number of winding of a winding holding part As the number increases, the coupling between them can be strengthened, and the mounting stability can be improved.

 In the figure, the lower surface mesh portion 10 is a portion where a surface on which embankments are stacked in a plurality of layers is formed as a mesh surface. Further, the rising net portion 20 is formed as a surface having an angle between the lower surface net portion 10 and an acute angle θ smaller than 90 degrees, and a net surface that prevents the embankment from spilling out. It is formed by bending a net formed continuously with the lower surface net part 10. The angle θ between the lower surface mesh portion 10 and the rising mesh portion 20 is an angle determined by the angle θ of the slope to be constructed, and a range of about 80 degrees to 60 degrees that is 90 degrees or less is usually selected. However, depending on the situation of the reinforcing part, even the reinforcing part on the same slope may be 80 degrees or 60 degrees depending on the position, and in particular, the rising net 20 may be partially curved. Therefore, the angle between the bottom mesh portion 10 and the rising mesh portion 20 is usually θ = 90 degrees or less and is used as a form of θ = 30 degrees or more, and their width is also used within a range of 50 cm to 200 cm. Usually, it is set based on the standard of the metal net. Note that a mesh ground reinforcing member 70 formed of synthetic resin or the like is connected to the lower surface mesh portion 10 and used for the lower surface mesh portion 10.

In the present embodiment, the angle between the bottom mesh portion 10 and the rising mesh portion 20 is formed by bending a single net. However, when the present invention is carried out, It is also possible to use the rising net portion 20 as a cut net. Also in this case, the connector 40 of the present embodiment can be used. Of course, other connection means can be used, and since it is usually formed by bending a single net, its description is omitted.
As the mesh, a welded wire mesh, plain woven wire mesh, rhombus wire mesh, turtle shell wire mesh or the like can be used, and the expanded metal 1 shown in FIG. 3 has high mechanical strength and can easily maintain a stable form. When the rhombus wire mesh 2 and the turtle shell wire mesh 3 are used, the flexibility is high, and it can be appropriately selected depending on the shape of the slope.

Incidentally, the cross-section of the expanded metal 1 shown in FIG. 3A has a cross section of about 5 mm □ (square), and the rhombus opening has a vertical direction Ly of about 150 mm and a horizontal direction Lx of about 50 mm. The rhombus metal mesh 2 shown in FIG. 3B has a wire diameter of about 4 mm, and the rhombus opening has a vertical direction Ly of about 80 mm and a horizontal direction Lx of about 160 mm. 3C has a wire diameter of about 4 mm, and its opening has a vertical direction Ly of about 80 mm and a horizontal direction Lx of about 40 mm.
Here, the wire diameter forming the mesh and the opening of the mesh can be arbitrarily changed according to the product standard of the mesh according to the required strength and the like. Moreover, the length of the opening in the vertical direction and the horizontal direction can be arbitrarily set.

 Further, the cross section of the mesh cross forming the mesh opening as a mesh is usually about 8 mm square or about 8 mm or less in diameter, preferably about 5 mm square or less, preferably about 1.5 mm square or more from the viewpoint of flexibility and economy. The mesh is preferably about 120 mm or less from the aspect of durability, spillage of earth and sand, and planting. Materials include vinyl chloride coated iron wire, galvanized iron wire, colored painted galvanized iron wire, molten aluminum plated iron wire, zinc aluminum alloy plated iron wire, and high strength PVC coated special iron wire, which are selected as necessary. In the present embodiment, an expanded metal 1 made of molten aluminum plating is used. Although spillage of earth and sand is omitted in the figure, a vegetation sheet containing seeds such as turf is used, and the mesh does not directly prevent spillage of earth and sand.

 Thus, as the mesh, expanded metal 1, rhombus wire mesh 2, turtle shell wire mesh 3, welded wire mesh, plain weave wire mesh, etc. can be used, and in particular, as diamond wire mesh 2 and tortoise shell wire mesh 3 in which the intersecting portions of the wire rods are twisted several times. Also good. However, the rhombus wire mesh 2 and the turtle shell wire mesh 3 are connected in a twisted manner so that the intersecting portions of the wire rods can be easily deformed and flexible, so when implementing the present invention, The structure should be as flexible as possible.

The maintenance of the angle between the lower surface net 10 and the rising net 20 as the present embodiment is left to the hook metal fitting 30 as shown in FIG. Both ends of the hook metal fitting 30 are formed in a U (J) shape, and the U (J) shape end portions are connected to the lower surface net portion 10 and the net of the rising net portion 20. As shown in FIG. 9, when the earth and sand 50 is inserted into the hook metal fitting 30 within the angle between the lower surface mesh portion 10 and the rising net portion 20, the angle of the rising net portion 20 tends to rotate in a right angle direction. . Therefore, both ends of the hook metal fitting 30 are curved in a U (J) shape, and the angle can be prevented from spreading at both ends.
One hook metal fitting 30 is arranged at intervals of 50 to 200 cm with respect to the lateral direction of the lower surface net 10 and the rising net 20.

The angle between the bottom mesh portion 10 and the rising mesh portion 20 is maintained by the hook fitting 30. When viewed from the side, the triangle shape is formed, so that a shape with high mechanical strength can be maintained. As described above, the metal wall reinforcing retaining wall material formed by the lower surface mesh portion 10, the rising mesh portion 20, and the hook metal fitting 30, whose shape is maintained, is in the lateral direction of the lower surface mesh portion 10 and the rising mesh portion 20. By connecting and extending, the slope of a predetermined width of the height of the rising net portion 20 can be formed.
Further, in the height direction of the rising net portion 20, an end portion of the rising net portion 20 and a bent portion of the lower net portion 10 and the rising net portion 20 are connected to each other to have a predetermined height. can do.

Next, the horizontal connection of the rising net 20, the horizontal connection of the bottom net 10, and the vertical connection of the rising net 20 will be described with reference to FIGS. 4 to 7.
The coupling tool 40, which is formed entirely of an elastic wire, has a linear main body 41 and a winding holding portion formed at one end where a winding state of one turn or more wound in a substantially α shape is maintained. 43, and a locking portion 42 formed continuously from the winding holding portion 43 and having the other end elastically engaged with a mesh surface, for example, a mesh cross d of the expanded metal 1.

In the present embodiment, the connecting tool 40 formed entirely of an elastic wire uses a round wire having a substantially circular cross section. However, when the present invention is implemented, a square wire having a substantially square cross section, a cross section is used. It can also be a substantially rectangular flat wire. Depending on the method of forming the winding holding part 43 and the locking part 42, the square wire and the flat wire may have better mounting stability.
As shown in FIG. 4, the winding holding portion 43 has a diameter between the ends of the bottom mesh portion 10 and / or between the ends of the rising mesh portion 20. The diameter R is set such that there is a slight backlash in the state where the two are overlaid. That is, the diagonal lines of the cross-sectional areas of the crosspieces a and b between the ends of the lower face net 10 and between the ends of the rising net 20 are set to be equal to or less than the inner diameter thereof.

 Further, the pitch P of the winding holding portion 43 wound in a substantially α shape is set to be slightly narrower than the width between the end portions of the lower surface net portion 10 and / or between the end portions of the rising net portion 20. Is done. Therefore, when an external force is applied between the ends of the lower surface mesh portion 10 and / or between the ends of the raised mesh portion 20 and an external force is applied, the rising mesh portions It will be inserted between the 20 ends.

 And the latching | locking part 42 is continuously formed through the linear main-body part 41 from the winding holding | maintenance part 43, and the other edge part is formed so that it may elastically engage with the mesh | crosspiece C of a mesh surface. That is, if the locking portion 42 is a straight line, it moves when it is vibrated while in contact with the net. Therefore, in the present embodiment, it is bent into a crank shape and functions as a detent. In the present embodiment, the locking portion 42 is bent in a crank shape. However, when the present invention is implemented, the locking portion 42 is formed in a U shape, and the mesh bar on the mesh surface is interposed therebetween. It can be made to enter, and can also be formed as an L-shape. In any case, the locking portion 42 may be formed so as to be elastically engaged with the mesh bar on the mesh surface.

Next, the usage method of the connection tool 40 of a wall surface reinforcement retaining wall material is demonstrated.
As shown in FIG. 6, the outermost mesh nets b on the opposite side to the outermost mesh nets a between the ends of the lower surface mesh part 10 and between the ends of the rising net part 20. A pitch P is applied between the ends of the outermost mesh nets b and the outermost mesh nets b opposite to each other, and an external force is applied to the outermost mesh nets a. Between the ends of the outermost mesh nets b on the opposite side of the mesh nets a, between the ends of the outermost mesh nets b on the rising net 20, It will be inserted between the end parts which consist of.

The winding holding part 43 holds between the ends of the nets b of the outermost mesh on the opposite side of the nets a, and is a straight line that stands substantially 90 degrees with respect to the held plane. The main body 41 is tilted in the plane direction, and is rotated against the elasticity of the pitch P by 90 degrees or more along the plane. The connector 40 rotates in the three-dimensional space. That is, between the ends of the outermost mesh nets b on the opposite side of the outermost mesh nets a is wound into the winding state of the winding holding part 43 for one turn or more, and in this state, the straight line is further straightened. In the elastic region of the main body 41, and the straight main body 41 is curved and curved in a state where the main body 41 is in contact with another mesh bar and an adjacent net c of the same mesh. Thus, the engaging portion 42 is elastically engaged with the mesh bar d on the adjacent mesh surface.

 In this state, the main body 41 is located between the ends of the outermost mesh nets b on the opposite side of the outermost mesh nets a of the lower surface net 10 and the outermost nets of the rising nets 20.

If the ends of the outermost mesh nets b on the opposite side of the outer mesh nets a are connected to each other, the outermost nets on the opposite side of the outermost nets of the lower surface net part 10 are connected. Due to the connection with the mesh pier b of the net, the connection between the outermost mesh pedestal b on the opposite side and the outermost mesh pedestal b on the opposite side of the rising net 20 is planar. In addition, the rising net portions 20 are connected in a planar manner, and the lateral connection of the lower surface net portion 10 and the rising net portion 20 is completed.

 Further, between the upper rising net portion 20 ′ and the lower rising net portion 20, as shown in FIG. 2 and FIG. 7, for example, the upper loading net portion 20 is loaded inside the lower rising net portion 20. The rising net portion 20 'is disposed, and the upper rising net portion 20' and the lower rising net portion 20 are brought into contact with each other so that the four side nets of the mesh coincide with each other. The nets of the net of the rising net 20 and the nets of the upper net 20 'are brought into contact with each other, and the opening of the winding holding portion 43 with a pitch P is assigned between the nets of the net. Then, an external force is applied, and the upper rising net portion 20 ′ and the lower rising net portion 20 are inserted between the nets.

 Here, the lower surface net | network part 10 is a surface which receives the embankment which loads embankment in several layers, and is formed in the mesh surface. As the net, it is possible to use expanded metal 1, rhombus metal net 2, turtle shell metal net 3, welded metal net, plain weave metal net, or the like. In addition, the rising net portion 20 is formed as a sharp surface between the lower surface net portion 10 and prevents the embankment from spilling out, that is, a net surface forming a retaining wall surface. The bottom mesh portion 10 and the rising mesh portion 20 may be formed by bending what is integrally formed, or may be formed separately and connected. Usually, the angle θ at which the lower surface net 10 and the rising net 20 are joined is 90 degrees or less, which is an acute angle.

 In particular, the connecting tool 40 has a surface on which the embankment is stacked in a plurality of layers, is raised between the ends of the lower surface mesh portion 10 formed with a mesh surface, and between the lower surface mesh portion 10 as an acute angle θ surface, It connects between the ends of the rising net part 20 formed by forming a net surface to prevent the embankment from spilling out, and more specifically, a winding holding part formed entirely of an elastic body. 43 and a locking portion 42, and the winding holding portion 43 is in a winding state of one turn or more in a state where the end portions of the lower surface net portion 10 and the end portions of the rising net portion 20 are overlapped. The locking portion 42 is formed continuously from the winding holding portion 43, and the other end portion is formed so as to be elastically engaged with the mesh bar on the mesh surface.

The wall reinforcing retaining wall member or the wall reinforcing retaining wall connector 40 of the present embodiment has a winding holding portion 43 formed at one end where the winding state of the connector 40 is maintained for one turn or more. Is formed so as to be elastically engaged with the mesh bars on the mesh surface, with the pitch P being approximately α-shaped as the distance between the ends of the bottom mesh portion 10 or between the ends of the raised mesh portion 20. The engaging portion 42 may be an embodiment that is bent into a substantially crank shape or a substantially U shape.
Accordingly, it is possible to easily fit between the α-shaped pitches P with respect to the overlap between the end portions, and to constrain by the difference in the angle, and to elastically engage the mesh bars on the mesh surface. The engaging portion 42 formed in such a manner is bent in a substantially crank shape or a substantially U shape so as to be elastically contacted by an external force when it is elastically contacted with the net of the mesh surface. Even if it is moved after assembly at the construction site, the connected part will not easily come off.

Furthermore, the substantially α-shaped winding holding portion 43 formed at one end where the winding state of the coupling tool 40 of the present embodiment is maintained for one turn or more is set to be 1 turn or more and 2 turns or less. Therefore, as the number of turns of the winding holding portion 43 increases, the coupling between them can be strengthened, and the attachment stability can be improved.
In particular, if it is 1 turn or more and 2 turns or less, it is easy to mesh without being affected by the number of windings of the winding holding part 43, and it cannot be easily detached from the net. However, in winding more than two turns, the net must be rotated around the shaft, and work efficiency is reduced.

 The connection position of the substantially α-shaped winding holding portion 43 is not limited to the position shown in the above embodiment, and may be disposed at any position on the net. As a result, what is necessary is just to be able to maintain a stable connection state.
