[First Embodiment]
In describing the first embodiment, first, a conventional honeycomb three-dimensional reinforcing material and a honeycomb structure will be described as comparison objects.
FIG. 1 is a perspective view of a conventional honeycomb three-dimensional reinforcing material (3 cells) before expansion. The honeycomb-shaped three-dimensional reinforcing material 1 includes a plurality of strip-shaped resin or fiber sheet strips 2 arranged side by side in the thickness direction and repeatedly in a staggered manner at predetermined intervals to be partially joined at regular intervals. Are joined together. The honeycomb-shaped three-dimensional reinforcing material 1 is expanded in the extending direction a to form a honeycomb-shaped cell structure. Resin is preferable as the material used for the honeycomb-shaped three-dimensional reinforcing material, and among the resins, high-density polyethylene is preferable.

  In some cases, the strip material 2 is provided with holes 3 for discharging water accumulated in the cells. The hole may have any size or shape. The number of holes is preferably large, but if it is too large, the strength of the strip material is lowered, so that the number should not exceed 40% of the area of the strip material. Further, the holes may be arranged in series or in a staggered manner. However, the outermost strip material constituting the slope portion should look better when no holes are provided. FIG. 1 shows an example in which no hole is provided in the outermost strip material.

  FIG. 2 is a perspective view when the conventional honeycomb three-dimensional reinforcing material (3 cells) shown in FIG. 1 is stretched. When the honeycomb-shaped three-dimensional reinforcing material 1 is stretched, honeycomb-shaped cells 5 are formed. As a general method of using the honeycomb-shaped three-dimensional reinforcing material 1, the honeycomb-shaped three-dimensional reinforcing material cell 5 is filled with a filler to the height of the cell and compacted to form a rigid honeycomb structure 6. Let

  As a filler for filling the cells 5 of the expanded honeycomb three-dimensional reinforcing material, any soil material such as sand, earth and sand, and crushed stone can be used. As the filler, a solidified material such as concrete or mortar can be used.

  FIG. 3 is a perspective view of a honeycomb retaining wall (3 cells) constructed by stacking conventional honeycomb structures 6. A honeycomb retaining wall can be formed by stacking and constructing the honeycomb structures approximately horizontally. When the honeycomb structures 6 are stacked, if a step is not provided, a straight honeycomb retaining wall can be constructed. Further, when the honeycomb structure 6 is stacked, the slopes having slopes can be formed by retreating the layers to the natural ground side for each layer. Depending on the receding width of the honeycomb structure 6, various slopes of the slope can be formed.

Although the conventional example has been described so far, the first embodiment will be described below.
In FIG. 4, the perspective view before the expansion | deployment of the honeycomb-shaped solid reinforcement material (3 cells) of this invention was shown. The difference between the conventional honeycomb three-dimensional reinforcing material shown in FIG. 1 and the honeycomb three-dimensional reinforcing material of the present invention is that a portion of the strip material 2 constituting the honeycomb three-dimensional reinforcing material to be a linear design ( The dividing portion 7 is attached to the strip material (the straight portion strip material 2A) of the wall surface portion when the honeycomb retaining wall is used. The dividing portion 7 must be provided between each portion of the straight portion strip material joint portion 4A, which is a joint portion between the straight portion strip material 2A and the adjacent strip material 2. The dividing portion 7 completely separates the straight portion strip material 2A.

  The position of the dividing portion 7 may be any position between the respective straight portion strip material joint portions 4A, but it is preferable to determine the position in consideration of the convenience of connecting the dividing portions to be performed later. That is, when connecting the parting part 7, it considers so that a connection member can be installed successfully.

  The production of the dividing portion 7 of the straight strip material 2A may be performed at the timing when the honeycomb-shaped solid reinforcing material is produced at the factory, or the honeycomb-shaped three-dimensional reinforcing material having no dividing portion is brought into the construction site and the dividing portion is simultaneously formed. 7 may be produced. As a method for producing the divided portion 7, a honeycomb-shaped three-dimensional reinforcing material including a straight portion strip material that does not have the divided portion 7 may be produced, and then the straight portion strip material may be cut to produce a divided portion. Alternatively, a method may be used in which a honeycomb-shaped three-dimensional reinforcing material having no straight part strip material is manufactured, and then a piece of the straight part strip material that has been divided in advance is joined to the joining portion.

  FIG. 5 is a perspective view when the honeycomb-shaped three-dimensional reinforcing material (3 cells) of the present invention shown in FIG. 4 is stretched. The difference between the conventional honeycomb three-dimensional reinforcing material shown in FIG. 2 and the honeycomb three-dimensional reinforcing material of the present invention is that a portion of the strip material 2 constituting the honeycomb three-dimensional reinforcing material to be a linear design ( This is the point that the dividing portion 7 is attached to the strip material (the straight portion strip material 2A) of the wall surface portion or the like when the honeycomb retaining wall is formed, which is shown in the figure. In FIG. 5, the example which has a parting part in the middle between each linear part strip material junction part 4A was shown.

  FIG. 6 is a perspective view when a straight portion is manufactured with the honeycomb-shaped three-dimensional reinforcing material of the present invention (strip material folding step). The straight portion of the honeycomb-shaped three-dimensional reinforcing material is produced by folding the left strip material (straight portion left piece) 2B and the right strip material (straight portion right piece) 2C to the cell side with the dividing portion 7 as a boundary ( Folding direction B), the strip material (straight portion left piece) 2B and the right strip material (straight portion right piece) 2C are overlapped. At this time, either the strip material (straight portion left piece) 2B or the right strip material (straight portion right piece) 2C may be on the cell side.

  FIG. 7 is a perspective view when a straight portion is produced with the honeycomb-shaped three-dimensional reinforcing material of the present invention (when strip materials are overlapped). FIG. 7 shows an example in which the strip material (straight portion left piece) 2B is overlapped with the cell side, and the strip material (straight portion right piece) 2C is on the outside. In order to obtain straightness of the straight portion, it is preferable that the left piece 2B and the right piece 2C are firmly pulled toward the center of the cell so as not to loosen. The two overlapped strip materials are connected in the next step.

  FIG. 8 is a perspective view when a straight portion is manufactured by the honeycomb-shaped three-dimensional reinforcing material of the present invention (connection by screwing of strip material pieces). FIG. 8 shows a completed view in which the strip material (straight portion left piece) 2B and the strip material (straight portion right piece) 2C are fastened with two screws 8. FIG. The number of screws illustrated is two, but any number is possible, and the greater the number, the greater the connection strength. On the other hand, the greater the number, the more labor is required for construction.

FIG. 9 is a cross-sectional view showing a screwing procedure when a straight portion is manufactured with the honeycomb-shaped three-dimensional reinforcing material of the present invention.
Procedure 1 is a cross-sectional view before the screw is passed through the strip material. As shown in Step 1, on the part where the strip material (straight portion left piece) 2B and the strip material (straight portion right piece) 2C are overlapped, the screw 8 is attached from the strip material (straight portion right piece) 2C side (outside). Pass through. It is preferable to provide a hole with a drill or the like in the part through which the screw 8 is passed. A cap 9 for securing the tip end of the screw 8 is prepared in advance on the strip material (straight portion left piece) 2B side (cell side).
The procedure 2 illustrates the moment when the screw 8 is passed through a portion where the strip material (straight line portion left piece) 2B and the strip material (straight line portion right piece) 2C are overlapped.
In step 3, the screw 8 penetrates the portion where the strip material (straight portion left piece) 2B and the strip material (straight portion right piece) 2C are overlapped, and then the tip portion of the biz 8 is fastened with the cap 9 from the opposite side. FIG.

  The screw 8 may be any screw as long as the strength is sufficient, and may be made of metal or resin. To firmly fix the strip material (straight-line left piece) 2B and strip material (straight-line right piece) 2C overlapped at the connecting part, strip material (straight-line left piece) 2B and strip material (straight-line right piece) The screw must be longer than the thickness of 2C. Further, since the head portion of the screw 8 falls off if it is not larger than the hole formed in the strip material (straight portion left piece) 2B and the strip material (straight portion right piece) 2C, it is made larger than the hole diameter.

  The cap 9 is a member necessary for fixing the screw, and preferably has a cap shape that fits into the screw 8 firmly. Any screw may be used as long as the material has sufficient strength, and it may be made of metal or resin. It may also be a nut. However, the minimum necessary condition is that the hole is larger than the hole formed in the strip material (straight portion left piece) 2B and the strip material (straight portion right piece) 2C.

  When a material such as a rivet is used for the screw 8, the cap 9 is not necessarily required. That is, in the case of rivets, the screw material is passed through the holes made in the strip material (straight portion left piece) 2B and the strip material (straight portion right piece) 2C, and then the opposite protruding portion is crushed with a hammer or the like. It is because it is possible to fix by.

  FIG. 9 is a perspective view of the honeycomb retaining wall (3 cells) of the present invention. FIG. 9 shows a honeycomb retaining wall when the honeycomb structure of the present invention is laminated stepwise. As is clear from the comparison with FIG. 3, the honeycomb retaining wall of the present invention does not show a wavy curved structure on the wall surface portion unlike the conventional honeycomb retaining wall. Moreover, when the honeycomb structure of the present invention is laminated without a step, a straight wall having a straight wall surface can be constructed.

In this embodiment, the procedures from FIG. 4 to FIG. 7 are common. That is, since it is the same as the procedure described in paragraphs 0030 to 0035, it is omitted.

  FIG. 11 is a perspective view in which strip material pieces are connected by a binding string when a straight portion is manufactured with the honeycomb-shaped three-dimensional reinforcing material of the present invention. FIG. 11 shows a completed view in which the strip material (straight line portion left piece) 2B and the strip material (straight line portion right piece) 2C are fastened with binding straps. The number of binding straps illustrated is one, but any number is possible, and the greater the number, the greater the connection strength.

  The binding string 10 may be any string as long as the strength is sufficient, and may be a resin molded product or a pair string. In particular, a binding band that can fix one end of the resin molded product at the other end is preferable. Examples of such a binding band include Insulok ties (“Insulok” is a registered trademark of Heraman Tighton) and Tie Wrap (registered trademark of Thomas and Bets).

  FIG. 12 is a perspective view illustrating an example of a binding string. In particular, the illustration is shown for Insulok ties (“Insulok” is a registered trademark of Heraman Tighton Co.).
