Description

  The present invention provides a design by fixing a flat material made of a flexible material using a locking means so as to cover the outer surface of a sheet constituting the side surface of the honeycomb-shaped three-dimensional three-dimensional cell structure. The present invention relates to a method for laying the structure with improved properties.

Conventionally, in the field of civil engineering and construction, the following patent documents are used to support heavy loads and prevent erosion as ground reinforcement materials for road roadbed materials, sidewalk foundation materials, temporary roads and retaining walls, etc. A honeycomb-like three-dimensional three-dimensional cell structure as disclosed in No. 1 is generally used.
For example, as shown in FIG. 1, such a cell structure is formed by repeatedly joining a plurality of long pieces of resin or fiber sheets arranged in parallel in the width direction in a staggered manner at predetermined intervals. When stretched in a direction orthogonal to the direction, a large number of honeycomb-shaped cells surrounded by the sheet are formed.

  Such a honeycomb-shaped three-dimensional three-dimensional cell structure is characterized by being light in weight and excellent in strength due to the cell structure described above. Such a honeycomb-shaped three-dimensional cell structure is usually transported to a laying site in a folded state as a block having a certain size, and is used after being expanded on the site. For example, a honeycomb-shaped three-dimensional three-dimensional cell structure is formed by laminating and laying a plurality of blocks as a plurality of blocks on a substantially flat ground surface, for example, a slope or slope of a river bank, and connecting the blocks to each other. Each cell is filled with a filler such as sand, crushed stone, concrete, or locally generated soil, and rolled to exert its function as a ground reinforcement.

Conventionally, a plurality of blocks to be laid are connected such that, for example, the outermost strips of adjacent blocks that are extended on the ground surface and laid in the same direction are sandwiched from above with a U-shaped nail, stapler, etc. It has been performed by various methods such as connecting. For example, in Patent Document 1 below, as shown in FIG. 1, an opening slot (groove hole) 36 provided in the convex region of the outermost strip of the adjacent honeycomb-shaped three-dimensional three-dimensional cell structure block, A method of connecting adjacent blocks by inserting a block connecting jig 24 having an insertion member 44 and a handle member 70 and rotating the block connecting jig 24 by about 90 degrees and the connecting jig are disclosed (FIG. 2). reference).
The side surface of the block of the honeycomb-shaped three-dimensional cell structure disclosed in Patent Document 1 has a wave shape corresponding to the shape of each cell (see FIG. 9). For this reason, there existed a subject that it cannot cope when it is preferable on a landscape to make this side surface into a substantially plane.

  On the other hand, the following Patent Document 2 is provided to fix the position of the side surface of the end portion of the honeycomb structure when the honeycomb structure in which the honeycomb-shaped three-dimensional reinforcing material is filled with earth and sand, crushed stone or the like is constructed. A support tool, comprising a rectangular plate in contact with the end surface of the honeycomb structure and a rectangular plate in contact with the ground surface. A vertically bonded honeycomb structure building support 8 is disclosed (see claims 1 and 2). As can be seen from FIGS. 3 to 5 attached to the present specification, since the support described in Patent Document 2 is L-shaped, it cannot follow the curved side surface of the cell structure, and the support Since the structure is complicated and it is described that the material is preferably a corrosion-resistant metal such as stainless steel (paragraph 0026), the cost is generally high.

  Further, the following Patent Document 3 is a mouthpiece formwork installed at the edge of a honeycomb retaining wall constructed by horizontally stacking a honeycomb structure filled with a filler in a honeycomb-shaped three-dimensional reinforcing material, There is described an L-shaped fore-edge mold comprising a wall surface and a bottom surface (see claim 1). As can be seen from FIGS. 6 to 8 attached to the present specification, since it is literally L-shaped, it cannot follow the curved side surface of the cell structure, and zinc is 80 to 95% by weight for improving corrosion resistance. And a steel wire (paragraph 0028) or expanded metal (paragraph 0026) plated with an alloy of aluminum 5 to 20 wt.

  By the way, when laminating honeycomb-shaped three-dimensional cell structures, the outer wall surface of the laminated cell structure constructed using a linear mold is straight, but constructed without using a linear mold. If the outer wall of the laminated structure to be constructed is assumed to be not straight but curved in the first place, there is naturally no linear outer wall. Therefore, when it is desired to give design to the outer wall of the laminated cell structure, when marking or makeup is desired, or when the unevenness of each cell is made linear and the effective area is simplified, Patent Document 2 or The L-shaped form as described in No. 3 cannot be used. That is, at present, it has not been practiced to enhance the design and aesthetics by locking the flat material to the curved outermost sheet or strip of the cell structure.

The design can be enhanced by fixing to the sheet using a stopping means. Since the flat material according to the present invention is flexible, the tangent line of the convex portion of the sheet or strip located on the side surface of the cell structure is not linear and can be fixed to the sheet or strip even if it is curved. it can. Further, if the material of the flat material is resin or recycled resin, the cost is low. Further, for example, a conventional block connecting jig 24 can be used as the locking means (see FIGS. 1, 2, and 11). In the cell structure laying method according to the present invention, the flat member can be fixed to the cell structure by a locking means before and after the expansion. Alternatively, a stretched state is maintained by driving the pile into the ground in the outermost cell, and the flat material is attached to the pile via the sheet constituting the side surface of the cell structure, for example, a bolt and a nut. And can be fixed. In the case of fixing to a pile instead of a sheet, the verticality of the flat material becomes high and beautiful construction is possible. If the material of the pile is a resin or a recycled resin like the flat material, the cost is further reduced. A design or an appearance of the wall surface of the laminated cell structure can be enhanced by attaching a label or the like to the flat material.

[Honeycomb three-dimensional solid cell structure]
A plurality of long pieces of resin or fiber sheets arranged side by side in the width direction are partially joined in a staggered manner at predetermined intervals, and this is stretched in a direction perpendicular to the width direction to form a honeycomb-like shape. The honeycomb-shaped three-dimensional cell structure forming cells is generally used in civil engineering and other fields, such as roadbed materials, foundation materials for sidewalks, temporary roads and retaining walls, and protection of slopes on river dikes. As a ground reinforcement material, it can be used for supporting heavy loads, preventing erosion, etc., for example, as disclosed in Patent Document 1, a honeycomb-like three-dimensional three-dimensional cell structure, It is not limited. The material of the resin or fiber sheet is not particularly limited, but polyethylene is preferable from the viewpoint of weather resistance. The bonding interval (pitch) of the resin or fiber sheet is preferably 200 to 800 mm. The joining is performed by means such as heat fusion. Each block of the honeycomb-shaped three-dimensional three-dimensional cell structure preferably has 3 to 40 vertical cells and 5 to 10 horizontal cells. The size of the cell structure after expansion is preferably 700 to 6000 mm in length, 2000 to 3500 mm in width, and 100 to 400 mm in height of the long-sided resin or fiber sheet.

  Such a cell structure is generally folded into each block, carried to the site, spread on the surface of the construction site, connected to each other, sand, crushed stone, concrete, locally generated soil, etc. in each formed cell. For example, it is laid on the dike slope of a river. However, the blocks of the cell structure can also be used to build a bank wall or the like by being stacked.

  As shown in FIG. 1, an opening slot (groove hole) 36 is provided in the outermost convex region of the long piece-like resin or sheet 26 in the adjacent cell structure first block 20 and cell structure second block 22. It has been. Such an open slot (groove hole) 36 may be large enough to allow the block connecting jig 24 to penetrate therethrough. In this invention, as shown in FIG. 11, this block connection jig | tool 24 can be used also as the latching means which fixes a flat material.

[Locking means]
As described above, the locking means can be the block connecting jig 24 as shown in FIG. As other locking means, as shown in FIG. 10, a pile is driven into the ground in the outermost cell to maintain a stretched state, and a flat member is used as the sheet constituting the side surface of the cell structure. For example, the pile can be fixed using, for example, a bolt and a nut. If the flat material is not fixed to the sheet with the block connecting jig 24, but fixed to the pile, if the verticality of the pile is ensured, the perpendicularity of the flat material fixed to this will also be high. Beautiful construction is possible. If the material of the pile is a resin or a recycled resin like the flat material, the cost is further reduced. The locking means between the pile and the flat member can be, for example, a bolt and a nut, but is not limited thereto.

[Planar material made of flexible material]
As shown in FIGS. 10 and 11, a flat member made of a flexible material has a length in the vertical direction that is substantially the same as the vertical width of the sheet or strip of the cell structure and a certain horizontal direction (the width of the sheet). It can be a rectangular shape with a (direction) length. For example, it can be a rectangle of about 10-30 cm in length and 100-300 cm in width. Although it depends on the material of the flat material, the thickness of the flat material is, for example, about 0.5 mm to be flexible enough to allow the operator to perform construction easily and maintain the shape for a long time after construction. 5 mm is preferable. The material or material of the flat member is not particularly limited, but may be metal, plastic, woven fabric, nonwoven fabric, or the like as the flexible material. A weather-resistant resin or a recycled resin is preferable from the viewpoint of cost or environment. If necessary, a sign may be attached to the outer surface of the flat member, or an illustration may be drawn with paint. Since the flat material is used to enhance the design and aesthetics of the cell structure, it needs to be a material or material suitable for such use. From the viewpoint of workability, the weight of the flat member is preferably light.

  The flat material fixing method and the like according to the present invention will be apparent to those skilled in the art from FIGS.
